Kinds of Make-up Selected AbstractsProtein-Losing Enteropathy after Fontan OperationCONGENITAL HEART DISEASE, Issue 5 2007Jack Rychik MD ABSTRACT Protein-losing enteropathy (PLE) is a poorly understood and enigmatic disease process affecting patients with single ventricle after Fontan operation. In those afflicted, PLE after Fontan operation results in significant morbidity and mortality. The pathophysiology of the disease is unknown; however, a proposed mechanism incorporates a combination of phenomena including: (1) altered hemodynamics, specifically low cardiac output; (2) increased mesenteric vascular resistance; (3) systemic inflammation; and (4) altered enterocyte basal membrane glycosaminoglycan make-up. A paradigm for the clinical management of PLE after Fontan operation is proposed. [source] Structuring the Classroom for Performance: Cooperative Learning with Instructor-Assigned Teams*DECISION SCIENCES JOURNAL OF INNOVATIVE EDUCATION, Issue 1 2003Gary D. Koppenhaver ABSTRACT The main concern is a longstanding one in classroom instruction,the determinants of effective team performance. The paper explicitly examines the effect of teacher-controlled factors on the use and functioning of student teams. From a sample of 500 undergraduate students, data are obtained on aptitude, diversity, instability, motivation, personality style, size, and performance. The regression results suggest that team motivation and instability, which are both partly controlled by the instructor, are particularly important in determining a team's performance. An implication is that instructor decisions about team make-up and incentives can have a significant impact on student achievement. [source] The Explainability of IntuitionsDIALECTICA, Issue 1 2004Nenad Mi Explaining intuitions in terms of "facts of our natural history" is compatible with rationally trusting them. This compatibilist view is defended in the present paper, focusing upon nomic and essentialist modal intuitions. The opposite, incompatibilist view alleges the following: If basic modal intuitions are due to our cognitive make-up or "imaginative habits" then the epistemologists are left with a mere non-rational feeling of compulsion on the side of the thinker. Intuitions then cannot inform us about modal reality. In contrast, the paper argues that there are several independent sources of justification which make the feeling of compulsion rational: the prima-facie and a priori ones come from the obviousness of our basic modal intuitions and our not being able to imagine things otherwise, others, a posteriori, from the epistemic success of these intuitions. Further, the general scheme of evolutionary learning is reliable, reliability is preserved in the resulting individual's cognitive make-up, and we can come to know this a posteriori. The a posteriori appeal to evolution thus plays a subsidiary role in justification, filling the remaining gap and removing the residual doubt. Explaining modal intuitions is compatible with moderate realism about modality itself. [source] Faunal make-up, host range and infestation rate of weevils and tephritid flies associated with flower heads of the thistle Cirsium (Cardueae: Astaraceae) in JapanENTOMOLOGICAL SCIENCE, Issue 4 2004Akinori NAKAMURA Abstract From 1988 to 1998, we collected flower heads of 39 thistle taxa (35 taxa of Cirsium, one species each of Breea, Synurus, Saussurea and Arctium; Cardueae; Astaraceae) in Japan, mainly from Hokuriku and other parts of central Honshu, and kept them in the laboratory to breed weevils and tephritid flies, the core fauna. We report the faunal make-up, host plants, geographic distribution and the attack levels of the insects. Results indicated that (i) three Larinus species (Curculionidae) and three species of tephritid flies (Tephritis, Urophora and Xyphosia) comprised the core fauna; (ii) two insect species belonging to the same taxonomic group (either Curculionidae (Larinus) or Tephritidae) tended to use different host plant species; (iii) two sympatric Larinus species (L. latissimus and L. meleagris) segregated the host plants seasonally in central Honshu (Cirsium blooming in spring and autumn, respectively); and (iv) two tephritid fly species, Xyphosia punctigera and Urophora sachalinensis, segregated geographically (the former on the Japan Sea side and the latter on the Pacific Ocean side). In comparison with their European counterparts, the weevils and tephritids of the Japanese Cirsium are characterized by a lower species richness and a lower degree of specialization in usage of the thistle flower heads, with gall-formers being distinctly under-represented, and callus tissue-feeders being absent. This reflects the fact that Japanese thistles are so closely related that hybridization frequently occurs, and also that the thistles have had a short history of interaction with the insects since the thistles' arrival in Japan. [source] Corruption and Entrepreneurship: How Formal and Informal Institutions Shape Small Firm Behavior in Transition and Mature Market EconomiesENTREPRENEURSHIP THEORY AND PRACTICE, Issue 5 2010Vartuhí Tonoyan This article explores the determinants of corruption in transition economies of the post-Soviet Union, Central-Eastern Europe, and Western industrialized states. We look in-depth at the East,West gap in corruption, and why entrepreneurs and small business owners become engaged in corrupt deals. Part of the answers lie in the country-specific formal and informal institutional make-up. The likelihood of engaging in corruption is influenced by the lower efficiency of financial and legal institutions and the lack of their enforcements. Also, viewing illegal business activities as a widespread business practice provides the rationale for entrepreneurs to justify their own corrupt activities. Moreover, closed social networks with family, friends, and national bureaucrats reduce the opportunism of the contracting party of the corrupt deal, thus providing breeding grounds for corruption. [source] Inflammatory airway disease, nasal discharge and respiratory infections in young British racehorsesEQUINE VETERINARY JOURNAL, Issue 3 2005J. L. N. WOOD Summary Reasons for performing study: Respiratory disease is important in young Thoroughbred racehorses, but the variation in the rates of occurrence between different ages and training groups has not been characterised. Objectives: To determine the rates of respiratory disease, particularly inflammatory airway disease (IAD), as well as evidence of infection, and their variation between age and group. Methods: Horses were examined monthly in 7 British flat training yards over a 3 year period. IAD was defined as increased mucus in the trachea with increased proportions of neutrophils in tracheal wash samples. Frequencies of disease outcomes were estimated from the data. Results: The prevalence of IAD was 13.8% and the incidence was 8.9 cases/100 horses/month. Rates varied with training and age groups, decreasing in older animals. The prevalence of nasal discharge (ND) was 4.1%. Rates of bacterial isolation were more common than viral infections. The incidence and prevalence of several bacterial species decreased with age. Conclusions: IAD and ND were common in young racehorses, varying significantly between training groups and decreasing with age, consistent with infection playing a role in aetiology. Potential relevance: The high prevalence of IAD in 2-year-old horses in Britain suggests that routine endoscopic examination may be helpful in providing early diagnosis and appropriate therapy. The transmission of bacteria and viruses within and between groups of young animals and the role of infection, stable environment and factors inherent to each horse, including their genetic make-up, in the multifactorial aetiology of the disease all merit further study. [source] On the Background and Motivation of Students in a Beginning Spanish ProgramFOREIGN LANGUAGE ANNALS, Issue 5 2002Article first published online: 9 SEP 2010, Paul B. Mandell ABSTRACT: A number of recent articles have examined the motivation, purpose of study, and demographics of first- and second-year language learners of French or Spanish (see, e.g., Ossipov, 2000; Rava, 2000; Voght, 2000; Wen, 1997) This study surveyed the make-up of a sample of first-and second-year university-level Spanish learners at a major postsecondary institution in a city with a substantial, growing population of monolingual and bilingual Spanish speakers. The results of the survey were used to address questions about learner preparation prior to entering a four-year university course of study, preferred and desired activities in the current curriculum, and motivations for the study of Spanish. Generalizations about the nature of the typical learner in this context and the implications of the appreciation of and desire for grammar-related and communicative activities , as expressed by the respondents , in the contemporary liberal arts curriculum are discussed. [source] COMMUNITY, OBLIGATION, AND FOOD: LESSONS FROM THE MORAL GEOGRAPHY OF INUITGEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 3 2010Nicole Gombay ABSTRACT. Using Inuit as an illustration, this article discusses what it means to live in community, and argues that by taking people's moral geographies into account one may understand more fully the make-up of community. The article maintains that their moral geography creates a feeling among Inuit of obligation for the other. It is this obligation that serves as the basis for community. The article theorizes about the implications of internalized mores based on obligation, and discusses how, in contrast to the concept of rights, such mores contribute to the formation and maintenance of community. The article concludes that developing a situated understanding of people's moral geographies may help to expand our comprehension of community construction and maintenance. [source] Determinants of HMO Formulary Adoption DecisionsHEALTH SERVICES RESEARCH, Issue 1p1 2003David Dranove Objective. To identify economic and organizational characteristics that affect the likelihood that health maintenance organizations (HMOs) include new drugs on their formularies. Data Sources. We administered an original survey to directors of pharmacy at 75 HMOs, of which 41 returned usable responses. We obtained drug-specific data from an industry trade journal. Study Design. We performed multivariate logistic regression analysis, adjusting for fixed-drug effects and random-HMO effects. We used factor analysis to limit the number of predictors. Data Collection Methods. We held initial focus groups to help with survey design. We administered the survey in two waves. We asked respondents to report on seven popular new drugs, and to describe a variety of HMO organizational characteristics. Principal Findings. Several HMO organizational characteristics, including nonprofit status, the incentives facing the director of the pharmacy, size and make-up of the pharmacy and therapeutics committee, and relationships with drugs makers, all affect formulary adoption. Conclusions. There are many organizational factors that may cause HMOs to make different formulary adoption decisions for certain prescription drugs. [source] Cover Picture: Biomineralized Polysaccharide Capsules for Encapsulation, Organization, and Delivery of Human Cell Types and Growth Factors (Adv. Funct.ADVANCED FUNCTIONAL MATERIALS, Issue 6 2005Mater. Abstract The cover shows biomineralized polysaccharide capsules with specifiable make-up, which can provide microenvironments for stabilization, growth, and differentiation of human cell types, as reported by Oreffo and co-workers on p.,917. The capsules are amenable to complexation with a range of bioactive molecules and cells, offering tremendous potential as multifunctional scaffolds and delivery vehicles in tissue regeneration of hard and soft tissues. The construction of biomimetic microenvironments with specific chemical and physical cues for the organization and modulation of a variety of cell populations is of key importance in tissue engineering. We show that a range of human cell types, including promyoblasts, chondrocytes, adipocytes, adenovirally transduced osteoprogenitors, immunoselected mesenchymal stem cells, and the osteogenic factor, rhBMP-2 (BMP: bone morphogenic protein), can be successfully encapsulated within mineralized polysaccharide capsules without loss of function in vivo. By controlling the extent of mineralization within the alginate/chitosan shell membrane, degradation of the shell wall and release of cells or rhBMP-2 into the surrounding medium can be regulated. In addition, we describe for the first time the ability to generate bead-in-bead capsules consisting of spatially separated cell populations and temporally separated biomolecule release, entrapped within alginate/chitosan shells of variable thickness, mineralization, and stability. Such materials offer significant potential as multifunctional scaffolds and delivery vehicles in tissue regeneration of hard and soft tissues. [source] The Battle of Chester and Warfare in Post-Roman BritainHISTORY, Issue 318 2010SEAN DAVIES Archaeological work at Heronbridge near Chester has recently uncovered the earliest identifiable site of a major British battlefield and investigated a related seventh-century fortification on the site. This article uses the new evidence to help interpret the battle of Chester's political background, the make-up of the forces on the day, their motivations, the equipment used and the course of the conflict, suggesting that the construction of the remarkable fortification was a key factor in the decision to engage in a battle that contravened the usual tactical principles of the age. The clash is set in the wider context of warfare in post-Roman Europe, providing insights into the development of both the Anglo-Saxon and British kingdoms that had emerged in the former imperial province of Britannia. [source] The extensive polymorphism of KIR genesIMMUNOLOGY, Issue 1 2010Derek Middleton Summary The functions of human natural killer (NK) cells are controlled by diverse families of antigen receptors. Prominent among these are the killer cell immunoglobulin-like receptors (KIR), a family of genes clustered in one of the most variable regions of the human genome. Within this review we discuss the vast polymorphism of the KIR gene complex which rivals that of the human leucocyte antigen (HLA) complex. There are several aspects to this polymorphism. Initially there is presence/absence of individual KIR genes, with four of these genes, termed framework genes, being present in all individuals tested to date, except on those very occasional instances when the gene has been deleted. Within each gene, alleles are present at different frequencies. We provide details of a new website that enables convenient searching for data on KIR gene, allele and genotype frequencies in different populations and show how these frequencies vary in different worldwide populations and the high probability of individuals differing in their KIR repertoire when both gene and allele polymorphism is considered. The KIR genes present in an individual may be classified into A and/or B haplotypes, which respectively have a more inhibitory role or a more activating role on the function of the NK cell. Family studies have been used to ascertain the make-up of these haplotypes, inclusion of allele typing enabling determination of whether one or two copies of a particular gene is present. In addition to genetic diversification the KIR gene complex shows differences at the functional level with different alleles having different protein expression levels and different avidity with their HLA ligand. [source] Automated loop identification on DSL linesINTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 12 2009Article first published online: 8 JUN 200, Kenneth J. Kerpez Abstract Regular ADSL and new FTTN VDSL2 deployments are strongly affected by the telephone loop, or channel, that they transmit over. Telephone companies keep records of the loop make-up,all cable sections, gauges, lengths and bridged taps between the DSLAM and customer, and these records are vital for loop qualification and maintenance. However, loop records are often incomplete or inaccurate due to re-work. New ADSL2, ADSL2 + and VDSL2 equipment can automatically report loop response estimates, and this paper shows how this response can be used to identify an estimate of the loop make-up. The algorithm for loop identification here is shown to be more accurate than previous, simple, techniques. Copyright © 2009 John Wiley & Sons, Ltd. [source] Quantifying the influence of sociality on population structure in bottlenose dolphinsJOURNAL OF ANIMAL ECOLOGY, Issue 1 2006DAVID LUSSEAU Summary 1The social structure of a population plays a key role in many aspects of its ecology and biology. It influences its genetic make-up, the way diseases spread through it and the way animals exploit their environment. However, the description of social structure in nonprimate animals is receiving little attention because of the difficulty in abstracting social structure from the description of association patterns between individuals. 2Here we focus on recently developed analytical techniques that facilitate inference about social structure from association patterns. We apply them to the population of bottlenose dolphins residing along the Scottish east coast, to detect the presence of communities within this population and infer its social structure from the temporal variation in association patterns between individuals. 3Using network analytical techniques, we show that the population is composed of two social units with restricted interactions. These two units seem to be related to known differences in the ranging pattern of individuals. By examining social structuring at different spatial scales, we confirm that the identification of these two units is the result of genuine social affiliation and is not an artefact of their spatial distribution. 4We also show that the structure of this fission-fusion society relies principally on short-term casual acquaintances lasting a few days with a smaller proportion of associations lasting several years. These findings highlight how network analyses can be used to detect and understand the forces driving social organization of bottlenose dolphins and other social species. [source] A novel direct aerodynamically assisted threading methodology for generating biologically viable microthreads encapsulating living primary cellsJOURNAL OF APPLIED POLYMER SCIENCE, Issue 2 2008Sumathy Arumuganathar Abstract In a recent discovery, coaxial electrospinning was explored to encapsulate living organisms within a continuous bio-polymeric microthread from which active biological scaffolds were fabricated (Townsend-Nicholson and Jayasinghe, Biomacromolecules 2006, 7, 3364). The cells were demonstrated to have gone through all expected cellular activity without their viability being compromised. These biologically active threads and scaffolds have direct and tremendous applicability from regenerative to therapeutic medicine. Currently these post-processed cells as composite threads and scaffolds are being investigated in-depth at a cellular level to establish if the processing methodology has any affect on the cellular make-up. We now demonstrate a competing non-electric field driven approach for fabricating composite threads and scaffolds influenced only by a differential pressure. We refer to this novel composite thread to scaffold fabrication methodology as coaxial aerodynamically assisted bio-threading (CAABT). Our investigations firstly, demonstrate that this technique can process handle living organisms without biologically perturbing them in anyway. Secondly the process is elucidated as possessing the ability to form composite active threads from which biologically viable scaffolds are formed. Finally our study employs florescent activated cell sorting (FACScan), a method by which the cellular dynamics and viability are quantified on control and threaded cellular samples at two prescribed time points. In parallel with FACScan, optical comparison of cellular morphology at three time points within a period of three weeks is carried out to photographically observe any changes in the post-processed cellular phenotype. Our developmental investigations into this novel aerodynamically assisted threading methodology has unearthed a unique biomicrofabrication approach, which joins cell electrospinning in the cell threading to scaffold fabrication endeavor. © 2007 Wiley Periodicals, Inc.

We aim to assess phytogeographical patterns in the bryophyte floras of oak forests and páramo of the Cordillera de Talamanca, Costa Rica. Location, Tropical America, in particular the montane area of Cordillera de Talamanca, Costa Rica. Methods, The analysis is based on a new critical inventory of the montane bryophyte flora of Cordillera de Talamanca. All species were assigned to phytogeographical elements on the basis of their currently known distribution. Absolute and percentage similarities were employed to evaluate floristic affinities. Results, A total of 401 species [191 hepatics (liverworts), one hornwort, 209 mosses] are recorded; of these, 251 species (128 hepatics, one hornwort, 122 mosses) occur in oak forests. Ninety-three per cent of all oak forest species are tropical in distribution, the remaining 7% are temperate (4%) and cosmopolitan (3%) species. The neotropical element includes almost 74% of the species, the wide tropical element (pantropical, amphi-atlantic, amphi-pacific) only 19%. A significant part of the neotropical species from oak forests are species with tropical Andean-centred ranges (27%). As compared with bryophyte species, vascular plant genera in the study region are represented by fewer neotropical, more temperate and more amphi-pacific taxa. Bryophyte floras of different microhabitats within the oak forest and epiphytic bryophyte floras on Quercus copeyensis in primary, early secondary and late secondary oak forest show a similar phytogeographical make-up to the total oak forest bryophyte flora. Comparison of oak forest and páramo reveals a greater affinity of the páramo bryophyte flora to temperate regions and the great importance of the páramo element in páramo. Surprisingly, oak forests have more Central American endemics than páramo. Main conclusions, (1) Providing first insights into the phytogeographical patterns of the bryophyte flora of oak forests and páramo, we are able to confirm general phytogeographical trends recorded from vascular plant genera of the study area although the latter were more rich in temperate taxa. (2) Andean-centred species are a conspicuous element in the bryophyte flora of Cordillera de Talamanca, reflecting the close historical connection between the montane bryophyte floras of Costa Rica and South America. (3) High percentages of Central American endemics in the bryophyte flora of the oak forests suggest the importance of climatic changes associated with Pleistocene glaciations for allopatric speciation. [source] Temporal and spatial genetic variation in a metapopulation of the annual Erysimum cheiranthoides on stony river banksJOURNAL OF ECOLOGY, Issue 1 2009Olivier Honnay Summary 1Metapopulation dynamics , the recurrent extinction and colonization in spatially discrete habitats , is expected to strongly affect within and between population genetic diversity. So far, however, accounts of true plant metapopulations are extremely scarce. 2We monitored the colonization and extinction dynamics of an assemblage of populations of the annual Erysimum cheiranthoides on stony river banks during three consecutive years. Each year, winter flooding drives some populations to extinction, while vacant banks may become colonized. We describe the dynamics of these ephemeral populations using amplified fragment length polymorphism (AFLP) markers to quantify changes in the metapopulation genetic structure over time, and assessing the direction and relative amount of migration and colonization events. 3Average extinction and colonization rates were high (0.39 and 0.34, respectively). While population genetic differentiation (FST) tripled from 0.06 in 2005 to 0.17 in 2007, total metapopulation genetic diversity remained fairly constant through the years. Genetic assignment analyses allowed assigning more than 50% of the genotyped individuals to populations extant the year before. Colonizing individuals originated from different source populations (, << 1) and there was considerable evidence of upstream seed dispersal. 4The degree and pattern of spatial genetic structure varied between years and was related to variation in the flooding intensity of the Meuse River through the years. Possibly, activation of the soil seed bank also played a role in structuring the genetic make-up of the populations. 5Because migration and colonization events were qualitatively equal, and colonizing individuals originated from different sources, the increase in FST was in agreement with previous theoretical work. Very high migration and colonization rates, and the short monitoring period, may explain why there was no loss of genetic diversity from the metapopulation through recurrent extinction and colonization events. 6Synthesis. This study gives one of the first accounts of the dynamics of a true plant metapopulation. Temporal monitoring of genetic variation gave evidence of extensive and bidirectional seed dispersal, highly variable and increasing genetic differentiation, and rather constant within population genetic diversity. An important suggestion from this research is to include a dormant seed stage in further theoretical work on (meta) population genetics. [source] Hegel, Human Rights, and ParticularismJOURNAL OF LAW AND SOCIETY, Issue 4 2003Richard Mullender Hegel's political philosophy gives prominence to the theme that human beings have a need for recognition of those qualities, characteristics, and attributes that make them distinctive. Hegel thus speaks to the question whether human rights law should recognize and accommodate the nuances of individual make-up. Likewise, he speaks to the question whether human rights law should be applied in ways that are sensitive to the cultural contexts in which it operates. But Hegel's political philosophy evaluates norms and practices within particular cultures by reference to the higher-order and universal criterion of abstract right. In light of this point and the inadequacies of political philosophy that privileges local norms and practices, a third approach to the protection of human rights is canvassed. This approach prioritizes neither universal nor local norms. Its aim is to ensure that both human rights and the cultures in which they are applied are taken seriously. [source] Organometallic Polymers of the Transition MetalsMACROMOLECULAR RAPID COMMUNICATIONS, Issue 17 2002Alaa S. Abd-El-Aziz Abstract This article provides a comprehensive review of the synthesis, properties and applications of organometallic polymers of the transition metals. The different classes of organometallic polymers are described according to their structural make-up, as well as by their methods of synthesis. A number of examples of each class are given to emphasize the richness and diversity in these areas of research. In addition to linear polymers, hyperbranched, crosslinked, star and dendritic polymers are also described. The properties that transition metal-containing organometallic polymers possess, as well as the applications that these materials have found in various domains are highlighted. [source] Cryptic behaviours, inverse genetic landscapes, and spatial avoidance of inbreeding in the Pacific jumping mouseMOLECULAR ECOLOGY, Issue 4 2007SACHA N. VIGNIERI Abstract Although the behaviour of individuals is known to impact the genetic make-up of a population, observed behavioural patterns do not always correspond to patterns of genetic structure. In particular, philopatric or dispersal-limited species often display lower-than-expected values of relatedness or inbreeding suggestive of the presence of cryptic migration, dispersal, or mating behaviours. I used a combination of microsatellite and mark,recapture data to test for the influence of such behaviours in a dispersal-limited species, the Pacific jumping mouse, within a semi-isolated population over three seasons. Despite short dispersal distances and a low rate of first generation migrants, heterozygosities were high and inbreeding values were low. Dispersal was male-biased; interestingly however, this pattern was only present when dispersal was considered to include movement away from paternal home range. Not unexpectedly, males were polygynous; notably, some females were also found to be polyandrous, selecting multiple neighbouring mates for their single annual litter. Patterns of genetic structure were consistent with these more inconspicuous behavioural patterns. Females were more closely related than males and isolation by distance was present only in females. Furthermore, detailed genetic landscapes revealed the existence of strong, significant negative correlations, with areas of low genetic distance among females overlapping spatially with areas of high genetic distance among males. These results support the hypothesis that the detected cryptic components of dispersal and mating behaviour are reducing the likelihood of inbreeding in this population through paternally driven spatial mixing of male genotypes and polyandry of females. [source] An extensive study of dynamical friction in dwarf galaxies: the role of stars, dark matter, halo profiles and MONDMONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, Issue 4 2006F. J. Sánchez-Salcedo ABSTRACT We investigate the in-spiralling time-scales of globular clusters (GCs) in dwarf spheroidal (dSph) and dwarf elliptical (dE) galaxies, due to dynamical friction (DF). We address the problem of these time-scales having been variously estimated in the literature as much shorter than a Hubble time. Using self-consistent two-component (dark matter and stars) models, we explore mechanisms which may yield extended DF time-scales in such systems in order to explain why dwarf galaxies often show GC systems. As a general rule, dark matter and stars both give a comparable contribution to the dynamical drag. By exploring various possibilities for their gravitational make-up, it is shown that these studies help to constrain the parameters of the dark matter haloes in these galaxies, as well as to test alternatives to dark matter. Under the assumption of a dark halo having a central density core with a typical King core radius somewhat larger than the observed stellar core radius, DF time-scales are naturally extended upwards of a Hubble time. Cuspy dark haloes yield time-scales ,4.5 Gyr, for any dark halo parameters in accordance with observations of stellar line-of-sight velocity dispersion in dSph galaxies. We confirm, after a detailed formulation of the DF problem under the alternative hypothesis of modified Newtonian dynamics (MOND) and in the lack of any dark matter, that due to the enhanced dynamical drag of the stars, the DF time-scales in MOND would be extremely short. Taking the well-measured structural parameters of the Fornax dSph and its GC system as a case study, we conclude that requiring DF time-scales comparable to the Hubble time strongly favours dark haloes with a central core. [source] Gene-environment interaction and obesityNUTRITION REVIEWS, Issue 12 2008Lu Qi The epidemic of obesity has become a major public health problem. Common-form obesity is underpinned by both environmental and genetic factors. Epidemiological studies have documented that increased intakes of energy and reduced consumption of high-fiber foods, as well as sedentary lifestyle, were among the major driving forces for the epidemic of obesity. Recent genome-wide association studies have identified several genes convincingly related to obesity risk, including the fat mass and obesity associated gene and the melanocortin-4 receptor gene. Testing gene-environment interaction is a relatively new field. This article reviews recent advances in identifying the genetic and environmental risk factors (lifestyle and diet) for obesity. The evidence for gene-environment interaction, especially from observational studies and randomized intervention trials, is examined specifically. Knowledge about the interplay between genetic and environmental components may facilitate the choice of more effective and specific measures for obesity prevention based on the personalized genetic make-up. [source] Predictors of Cardiac Arrest Occurring in the Context of Acute Myocardial InfarctionPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 10 2007HAITHAM HREYBE M.D. Background:Cardiac arrest (CA) concurrent with acute myocardial infarction (AMI) claims the life of many patients with coronary artery disease (CAD). In this study, we investigated the predictors of CA during AMI. Method:Patients admitted with CA concurrent with AMI (n = 31) were matched by age, gender, race, and left ventricular ejection fraction (LVEF) to patients with AMI but no CA (n = 70). All patients underwent coronary angiography. Binary logistic regression was used to identify independent predictors of CA during AMI. Results:A total of 101 patients (age = 61 ± 13 years, men 76%, Caucasians 98%, LVEF 33 ± 12%) admitted to the University of Pittsburgh Medical Center with AMI were included in this analysis. Patients with CA concurrent with the AMI were more likely to have proximal rather than distal coronary artery culprit lesions (odds ratio (OR) = 7.2, P = 0.019). Other predictors of CA in the context of AMI included negative family history of CAD (OR = 8.0, P = 0.026) and absence of sinus rhythm upon hospital admission (OR = 5.1, P = 0.030). Conclusion:Proximity of culprit coronary lesion and presence of rhythm other than sinus rhythm at hospital admission are two strong predictors of CA in the context of AMI. The implication is that the mechanism of CA is primarily that of a large area of myocardial ischemia leading to lethal ventricular arrhythmia. Other predispositions such as genetic make-up cannot be ruled out. [source] Civic Knowledge of High School Students in Israel: Personal and Contextual DeterminantsPOLITICAL PSYCHOLOGY, Issue 4 2007Professor Orit Ichilov Past research on civic education suggests that students' performance is largely influenced by individual socioeconomic background and motivational factors. There has been little attention to the effects of school and classroom ideological and social attributes, such as the socioeconomic make-up of the school or classroom, or how interested in politics are a student's classmates. The results of the present study support the contention that contextual effects play a vital role in determining students' civic knowledge scores. Analysis of Israeli 11th graders' performance on the International Association for the Evaluation of Educational Achievement (IEA) civic knowledge test shows that while individual backgrounds and motivations play a significant role, school and classroom contexts greatly contribute to civic knowledge acquisition. [source] Proceedings of the 20th Annual Conference of the Japanese Association for Adolescent Psychotherapy, 16 November 2002, Tokyo, JapanPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 5 2003Article first published online: 28 AUG 200 Inpatient treatment of obsessive,compulsive disorder in a child and adolescent psychiatry ward M. USAMI National Center of Neurology and Psychiatry, Kohnodai Hospital, Chiba, Japan This is a case report of a 13-year-old-boy (2nd grade in junior high school). His father had poor communication; his mother was a very fragile woman. The boy had been overprotected by his parents, as long as he responded to their expectations. He did not have any other siblings. He played well with his friends since he was young, and did not have problems until the 1st term (from April to July) of 1st grade in junior high school. However, in September he started to have difficulties going well with his friends, and going to school. He spent most of his time in his room, and began to repeat checking and hand-washing frequently. Even at midnight, he forced his mother to touch the shutter from outside of the house for many times. He also ritually repeated to touch his mother's body, after he licked his hands, for over an hour. He became violent, when his parents tried to stop him. In April, year X, his parents visited our hospital for the first time. From then, his mother could not tolerate her son's coerciveness any longer. His father explained to the boy that ,your mother has been hospitalized', and she started to live in the next room to the boy's without making any noise. After 3 months he noticed that his mother was not hospitalized, and he got very excited. He was admitted to our hospital with his family and relatives, in October, year X. At the initial stage of hospitalization he showed distrust and doubt towards the therapist and hospital. He had little communication with other boys and did not express his feelings. Therefore, there was a period of time where he seemed to wonder whether he could trust the treatment staff or not. During his interviews with his therapist he repeated only ,I'm okay' and did not show much emotional communication. For the boy, exposing himself was equivalent to showing his vulnerability and incompleteness. Therefore, the therapist considered that he was trying to denying his feelings to avoid this. The therapist set goals for considering his own feelings positively and expressing them appropriately. Also, the therapist carried out behavioral restrictions towards him. He hardly had any emotional communication with the staff, and his peer relationship in the ward was superficial. Therefore, he gradually had difficulty spending his time at the end of December On the following day in which he and the therapist decided to return to his house for the first time, he went out of the ward a few days before without permission. From thereon it was possible for him to share feelings such as hostility and aggression, dependence and kindness with the therapist. The therapist changed his role from an invasive one to a more protective one. Then, his unsociability gradually faded. He also developed good peer relationships with other boys in the ward and began to express himself feeling appropriately. He was also able to establish appropriate relations with his parents at home, and friends of his neighborhood began to have normal peer relationships again. During childhood and adolescence, boys with obsessive,compulsive disorder are known to have features such as poor insight and often involving their mothers. We would like to present this case, through our understanding of dynamic psychiatry throughout his hospitalization, and also on the other therapies that were performed. Psychotherapy with a graduate student that discontinued after only three sessions: Was it enough for this client? N. KATSUKI Sophia University, Tokyo, Japan Introduction: Before and after the psychotherapy, SWT was administrated in this case. Comparing these two drawings, the therapist was provided with some ideas of what kind of internal change had taken place inside this client. Referring to the changes observed, we would like to review the purposes and the ways of the psychotherapy, as well as the adequacy of the limited number of the sessions (vis-a-vis result attained.) Also we will discuss later if any other effective ways could be available within the capacities of the consulting system/the clinic in the university. Case: Ms. S Age 24 years. Problems/appeal: (i) awkwardness in the relationship with the laboratory colleagues; (ii) symptoms of sweating, vomiting and quivering; and (iii) anxiety regarding continuing study and job hunting. Diagnosis: > c/o PTSD. Psychotherapeutic setting: At the therapy room in the clinic, placed at the university, 50 min-session; once a week; paralleled with the medical treatment. Process: (1) Since she was expelled from the study team in the previous year, it has become extremely difficult for her to attend the laboratory (lab) due to the aforementioned symptoms. She had a feeling of being neglected by the others. When the therapist suggested that she compose her mental confusions in the past by attending the therapy room, she seemed to be looking forward to it, although she said that she could remember only a few. (2) She reported that she overdosed on sedatives, as she could not stop irritating. She was getting tough with her family, also she slashed the mattress of her bed with a knife for many times. She complained that people neither understood nor appreciated her properly. and she said that she wanted revenge on the leader of the lab by punishing him one way or other. (3) Looking back the previous session, she said ,I had been mentally mixed up at that time, but I feel that now I can handle myself, as I stopped the medication after consulting the psychiatrist. According to what she said, when she disclosed the occurrences in the lab to her mother, she felt to be understood properly by her mother and felt so relieved. and she also reported that she had been sewing up the mattress which she slashed before, without any reason. She added, " although I don't even know what it means, I feel that this work is so meaningful to me, somehow". Finally, she told that she had already made her mind to cope with the situation by herself from now on, although it might result in a flinch from the real solution. Situations being the above, the session was closed. Swt: By the remarkable changes observed between the two drawings, the meanings of this psychotherapy and its closure to the client would be contemplated. Question of how school counselors should deal with separation attendant on students' graduation: On a case in which the separation was not worked through C. ASAHARA Sophia University, Tokyo, Japan Although time limited relationship is one of the important characteristics in school counseling, the question of separation attendant on it has not been much discussed based on specific cases. This study focuses on the question of separation through looking at a particular case, in which the separation was not worked through, and halfway relationship continued even after the student's graduation and the counselor's resignation. I was a part time school counselor at a junior high school in Tokyo. The client was a 14-year-old female student, who could not go to her classroom, and spent a few hours in a sick bay when she came to school. She was in the final grade and there was only half a year left before graduation when we first met, and we started to see each other within a very loose structure. As her personality was hyper-vigilant and defensive, it took almost 2 months before I could feel that she was nearer. Her graduation was the first occasion of separation. On that occasion, I found that there had been a discrepancy between our expectations; while I took it for granted that our relationship would end with the graduation, she expected to see me even after she graduated, and she actually came up to see me once in a while during the next year. A year later, we faced another occasion of separation, that was my resignation. Although I worried about her, all I have done for her was to hand a leaflet of a counseling office, where I work as a part time counselor. Again I could not refer to her feelings or show any concrete directions such as making a fixed arrangement. After an occasional correspondence for the next 10 months (about 2 years after her graduation), she contacted me at the counseling office asking for a constant counseling. Why could I not deal with both occasions? and how did that affect the client thereafter? There were two occasions of separation. At the time of the client's graduation, I seemed to be enmeshed in the way of separation that is peculiar to the school setting. In general in therapeutic relationship, mourning work between counselor and client is regarded as being quite important. At school, however, separation attendant on graduation is usually taken for granted and mourning work for any personal relationship tends to be neglected. Graduation ceremony is a big event but it is not about mourning over one's personal relationships but separation from school. That may be why I did not appreciate how the client counted on our relationship. At the time of my resignation I was too worried about working through a change from very loose structure which is peculiar to the school setting to a usual therapeutic structure (fees are charged, and time, place are fixed). That is why I did nothing but give her a leaflet. In this way, we never talked about her complex feelings such as sadness or loneliness, which she was supposed to experience on separation. Looking at the aforementioned process from the client's viewpoint, it can be easily imagined that she could not accept the fact of separation just because she graduated. and later, she was forced to be in double-bind situation, in which she was accepted superficially (handed a leaflet), while no concrete possibility was proposed concerning our relationship (she could never see me unless she tries to contact me.) As a result, she was left alone and at a loss whether she could count on me or not. The halfway situation or her suspense was reflected in her letter, in which she appeared to be just chatting at first sight, but between the lines there was something more implying her sufferings. Above discussion suggests that in some case, we should not neglect the mourning work even in a school setting. To whom or how it is done is the next theme we should explore and discuss in the future. For now, we should at least be conscious about the question of separation in school setting. Study of the process of psychotherapy with intervals for months M. TERASHIMA Bunkyo Gakuin University, Tokyo, Japan This is a report on the process of psychotherapy of an adolescent girl who showed manic and depressive state. At the time of a depressed state, she could not go to a college and withdrew into home, and the severe regressive situation was shown. Her therapy began at the age of 20 and she wanted to know what her problem was. The process of treatment went on for 4 years but she stopped coming to sessions for several months because of failure of the therapist. She repeated the same thing twice. After going through these intervals the client began to remember and started to talk about her childhood , suffering abusive force from her father, with vivid impressions. They once were hard for her to accept, but she began to establish the consistent figure of herself from past to present. In this case, it could be thought that the intervals of the sessions had a certain role, with which the client controlled the structure of treatment, instead of an attack against the therapist. Her object relation, which is going to control an object offensively, was reflected in these phenomena. That is, it can be said that the ambivalence about dependency , difficult to depend but desirous of the object , was expressed. Discontinuation of the sessions was the product of the compromise formation brought about the ambivalence of the client, and while continuing to receive this ambivalence in the treatment, the client started to realize discontinuance of her memories and then advanced integration of her self-image. For the young client with conflict to dependence such as her, an interval does not destroy the process of treatment but in some cases it could be considered as a therapeutic element. In the intervals the client could assimilate the matter by herself, that acquired by the sessions. Psychotherapy for a schizoid woman who presented eccentric speech and behaviour M. OGASAWARA Osaka University Graduate School of Medicine, Osaka, Japan Case presentation: A case of a 27-year-old woman at the beginning of therapy. Life history: She had been having a wish for death since she was in kindergarten and she had been feeling strong resistance to do the same as others after school attendance. She had a history of ablutomania from the age of 10,15, but the symptom disappeared naturally. and she said that she had been eliminated from groups that she tried to enter. After graduating a junior college, she changed jobs several times without getting a full-time position. Present history: Scolded by her boy friend for her coming home too late one day, she showed confusion such as excitement, self-injury or terror. She consulted a psychiatrist in a certain general hospital, but she presented there eccentric behaviours such as tense facial expression, stiffness of her whole body, or involuntary movement of limbs. and because she felt on bad terms with the psychiatrist and she had come to cause convulsion attacks in the examination room, she was introduced to our hospital. Every session of this psychotherapy was held once a week and for approximately 60 min at a time. Treatment process: She sometimes presented various eccentric attitudes, for example overturning to the floor with screaming (1), going down on her knees when entrance at the door (5), entering with a knife in her mouth and hitting the wall suddenly (7), stiffening herself just outside the door without entering the examination room (9), taking out a knife abruptly and putting it on her neck (40), exclaiming with convulsion responding to every talk from the therapist (41), or stiffening her face and biting herself in the right forearm suddenly (52). She also repeated self-injuries or convulsion attacks outside of the examination room in the early period of the therapy. Throughout the therapy she showed hypersensitivity for interpersonal relations, anxiety about dependence, terror for self-assertion, and avoidance for confrontation to her emotional problems. Two years and 6 months have passed since the beginning of this therapy. She ceased self-injury approximately 1 year and 6 months before and her sense of obscure terror has been gradually reduced to some extent. Discussion: Her non-verbal wariness and aggression to the therapist made the sessions full of tension and the therapist felt a sense of heaviness every time. In contrast, she could not express aggression verbally to the therapist, and when the therapist tried to identify her aggression she denied it. Her anxiety, that she will be thoroughly counterattacked to self-disintegration if she shows aggression to other persons, seems to be so immeasurably strong that she is compelled to deny her own aggression. Interpretations and confrontations by the therapist make her protective, and occasionally she shows stronger resistance in the shape of denial of her problems or conversion symptoms (astasia, aphonia, or involuntary movements) but she never expresses verbal aggression to the therapist. and the therapist feels much difficulty to share sympathy with her, and she expresses distrust against sympathetic approach of the therapist. However, her obvious disturbance that she expresses when she feels the therapist is not sympathetic shows her desire for sympathy. Thus, because she has both strong distrust and desire for sympathy, she is in a porcupine dilemma, which is characteristic of schizoid patients as to whether to lengthen or to shorten the distance between herself and the therapist. This attitude seems to have been derived from experience she might have had during her babyhood and childhood that she felt terror to be counterattacked and deserted when she showed irritation to her mother. In fact, existence of severe problems of the relationship between herself and her mother in her babyhood and childhood can be guessed from her statement. Although she has been repeating experiences to be excluded from other people, she shows no attitude to construct interpersonal relationship actively. On the contrary, by regarding herself to be a victim or devaluating other persons she externalizes responsibility that she herself should assume essentially. The reason must be that her disintegration anxiety is evoked if she recognizes that she herself has problems; that is, that negative things exist inside of her. Therefore, she seems to be inhibited to get depressive position and obliged to remain mainly in a paranoid,schizoid position. As for the pathological level, she seems to have borderline personality organization because of frequent use of mechanisms to externalize fantastically her inner responsibility. For her high ability to avoid confronting her emotional problems making the most of her verbal ability, every intervention of the therapist is invalidated. So, it seems very difficult for her to recognize her own problems through verbal interpretations or confrontation by the therapist, for the present. In general, it is impossible to confront self problems without containing negative emotions inside of the self, but her ability seemed to be insufficient. So, to point out her problems is considered to be very likely to result in her confusion caused by persecution anxiety. Although the therapy may attain the stage on which verbal interpretation and confrontation work better some day, the therapist is compelled to aim at promoting her ability to hold negative emotion inside of herself for the time being. For the purpose, the therapist is required to endure the situation in which she brings emotion that makes the therapist feel negative counter-transference and her process to experience that the therapeutic relation itself would not collapse by holding negative emotion. On supportive psychotherapy with a male adolescent Y. TERASHIMA Kitasato University Health Care Center, Kanagawa, Japan Adolescent cases sometimes show dramatic improvements as a consequence of psychotherapy. The author describes how psychotherapy can support an adolescent and how theraputic achievements can be made. Two and a half years of treatment sessions with a male adolescent patient are presented. The patient was a 19-year-old man, living with his family. He had 5 years of experience living abroad with his family and he was a preparatory school student when he came to a mental clinic for help. He was suffering from not being able to sleep well, from difficulties concerning keeping his attention on one thing, and from fear of going to distant places. He could barely leave his room, and imagined the consequence of overdosing or jumping out of a window. He claimed that his life was doomed because his family moved from a town that was familiar to him. At the first phase of psychotherapy that lasted for approximately 1 year, the patient seldom responded to the therapist. The patient was basically silent. He told the therapist that the town he lives in now feels cold or that he wants to become a writer. However, these comments were made without any kind of explanation and the therapist felt it very difficult to understand what the patient was trying to say. The sessions continued on a regular basis. However, the therapist felt very useless and fatigued. Problems with the patient and his family were also present at this phase of psychotherapy. He felt unpleasant at home and felt it was useless to expect anything from his parents. These feelings were naturally transferred to the therapist and were interpreted. However, interpretation seemed to make no changes in the forms of the patient's transference. The second phase of psychotherapy began suddenly. The patient kept saying that he did not know what to talk about. However, after a brief comment made by the therapist on the author of the book he was reading, the patient told the therapist that it was unexpected that the therapist knew anything of his favorite writer. After this almost first interaction between the patient and the therapist, the patient started to show dramatic changes. The patient started to bring his favorite rock CDs to sessions where they were played and the patient and the therapist both made comments on how they felt about the music. He also started asking questions concerning the therapist. It seemed that the patient finally started to want to know the therapist. He started communicating. The patient was sometimes silent but that did not last long. The therapist no longer felt so useless and emotional interaction, which never took place in the first phase, now became dominant. The third phase happened rapidly and lasted for approximately 10 months. Conversations on music, art, literature and movies were made possible and the therapist seldom felt difficulties on following the patient's line of thought. He started to go to schools and it was difficult at first but he started adjusting to the environment of his new part-time jobs. By the end of the school year, he was qualified for the entrance to a prestigious university. The patient's problems had vanished except for some sleeping difficulties, and he did not wish to continue the psychotherapy sessions. The therapist's departure from the clinic added to this and the therapy was terminated. The patient at first reminded the therapist of severe psychological disturbances but the patient showed remarkable progress. Three points can be considered to have played important roles in the therapy presented. The first and the most important is the interpretation by behavior. The patient showed strong parental transference to the therapist and this led the therapist to feel useless and to feel fatigue. Content analysis and here-and-now analysis seemed to have played only a small part in the therapy. However, the therapist tried to keep in contact with the patient, although not so elegant, but tried to show that the therapist may not be useless. This was done by maintaining the framework of the therapy and by consulting the parents when it was considered necessary. Second point is the role that the therapist intentionally took as a model or target of introjection. With the help of behavioral interpretation that showed the therapist and others that it may not be useless, the patient started to introject what seemed to be useful to his well being. It can be considered that this role took some part in the patient going out and to adjust to the new environment. Last, fortune of mach must be considered. The patient and the therapist had much in common. It was very fortunate that the therapist knew anything about the patient's favorite writer. The therapist had some experience abroad when he was young. Although it is a matter of luck that the two had things in common, it can be said that the congeniality between the patient and the therapist played an important role in the successful termination of the therapy. From the physical complaint to the verbal appeal of A's recovery process to regain her self-confidence C. ITOKAWA and S. KAZUKAWA Toyama Mental Health Center, Toyama, Japan This is one of the cases at Toyama Mental Health Center about a client here, we will henceforth refer to her simply as ,A'. A was a second grade high school student. We worked with her until her high school graduation using our center's full functions; counseling, medical examination and the course for autogenic training (AT). She started her counseling by telling us that the reason for her frequent absences from school began because of stomach pains when she was under a lot of stress for 2 years of junior high school, from 2nd grade to 3rd grade. Due to a lack of self confidence and a constant fear of the people around her, she was unable to use the transportation. She would spend a large amount of time at the school infirmary because she suffered from self-diagnosed hypochondriac symptoms such as nausea, diarrhea and a palpitation. She continued that she might not be able to have the self-confidence to sit still to consult me on her feelings in one of our sessions. A therapist advised her to take the psychiatric examination and the use of AT and she actually saw the medical doctor. In counseling (sessions), she eventually started to talk about the abuse that started just after her entering of junior high school; she approached the school nurse but was unable to tell her own parents because she did not trust them. In doing so, she lost the rest of her confidence, affecting the way she looked at herself and thought of how others did. At school she behaved cheerfully and teachers often accused her of idleness as they regarded this girl's absences along with her brightly dyed hair and heavy make-up as her negligent laziness. I, as her therapist, contacted some of the school's staff and let them know of her situation in detail. As the scolding from the teachers decreased, we recognized the improvement of her situation. In order to recover from the missed academic exposure due to her long absence, she started to study by herself. In a couple of months her physical condition improved gradually, saying ,These days I have been doing well by myself, haven't I?' and one year later, her improved mental condition enabled her to go up to Tokyo for a concert and furthermore even to enjoy a short part-time job. She continued the session and the medical examination dually (in tangent) including the consultation about disbelief to the teachers, grade promotion, relationships between friends and physical conditions. Her story concentrated on the fact that she had not grown up with sufficiently warm and compassionate treatment and she could not gain any mental refuge in neither her family nor her school, or even her friends. Her prospects for the future had changed from the short-ranged one with no difficulty to the ambitious challenge: she aimed to try for her favorite major and hoped to go out of her prefecture. But she almost had to give up her own plan because the school forced her to change her course as they recommended. (because of the school's opposition with her own choice). So without the trust of the teachers combined with her low self-esteem she almost gave up her hopes and with them her forward momentum. In this situation as the therapist, I showed her great compassion and discussed the anger towards the school authorities, while encouraging this girl by persuading her that she should have enough self-confidence by herself. Through such sessions, she was sure that if she continued studying to improve her own academic ability by herself she could recognize the true meaning of striving forward. and eventually, she received her parents' support who had seemed to be indifferent to her. At last she could pass the university's entrance exams for the school that she had yearned to attend. That girl ,A' visited our center 1 month later to show us her vivid face. I saw a bright smile on her face. It was shining so brightly. [source] LOOKING DIFFERENT, ACTING DIFFERENT: STRUGGLES FOR EQUALITY WITHIN THE SOUTH AFRICAN POLICE SERVICEPUBLIC ADMINISTRATION, Issue 3 2008MONIQUE MARKS This descriptive paper tells the story of the daily difficulties that members of the Public Order Police (POP) unit in South Africa experienced in their attempts to create a more diverse (in terms of race and gender) and representative police organization. This story is told through recordings of observations and conversations that span a 4-year ethnographic journal. The paper demonstrates that despite affirmative action and equity legislation and programmes, Durban POP by the year 2001, six years after the transformation process within the unit began, was still plagued by deep racial and gender divisions. These divisions were reinforced by the structural make-up of the unit and the inability of middle management to challenge entrenched practices, as well as deep-seated assumptions, schemas and values associated with race, ethnicity and gender. By means of a ethnographic journal I was able to discover some of the daily dilemmas of the police in their change efforts and also the difficulties of getting police practice to meet new policy agendas. [source] Clothing and a Florentine style, 1550,1620RENAISSANCE STUDIES, Issue 1 2009Elizabeth Currie This article addresses the links between Renaissance clothing and identity, focusing on the reigns of the first Medici grand dukes, a period when the political and social make-up of the Florentine elite underwent profound changes. Drawing on a wide range of sources, from sumptuary legislation, court correspondence and family account books to tailors' patterns, it examines different ways of thinking about and analysing dress styles. Taking the under-explored subject of male dress, it concentrates on two specific clothing types: the traditional full-length cloak, known as the lucco, worn by government office holders, and the liveries of the Medici courtiers. It concludes with the role played by local textile production, a vital aspect of Florentine culture as well as its economy. Although the Medici family's efforts to shape the dress of its subjects were partially successful, certain fundamental elements of the city's sartorial ethos resisted change. [source] Lung cancer: Progress in diagnosis, staging and therapyRESPIROLOGY, Issue 1 2010Stephen G. SPIRO ABSTRACT Lung cancer remains one of the greatest medical challenges with nearly 1.5 million new cases worldwide each year and a growing tobacco epidemic in the developing world. This review summarizes briefly the current status in growing areas of clinical research. The value of screening for early disease is not yet established and trials to see if mortality can be improved as a result are in progress. Better and more accurate staging will both streamline investigation and prove cost-effective once ultrasound-guided biopsy and aspiration of mediastinal nodes become universally accepted. This, allied to the new staging classification, will improve selection of cases for surgery, intensive multimodality therapy and for adjuvant treatment postoperatively. Much still needs to be done to refine staging as within a particular stage group, the outcome shows great variation. More information is needed on the genetic make-up in some groups of tumours and not just their size; that is, more biological data on tumour growth patterns are likely to be at least as discriminating. The place of the stem cell theory of tumorigenesis is also explored in this paper. Finally, targeted therapy for advanced non-small-cell lung cancer is highlighted as a development with early promise, but still much clarification is required, before it can be considered as a universal approach in late disease. [source] A 19 Year Old with Complete Androgen Insensitivity Syndrome and Juvenile Fibroadenoma of the BreastTHE BREAST JOURNAL, Issue 6 2001Steven E. Davis MD We report a case of a 19-year-old female with complete androgen insensitivity syndrome (CAIS) who was diagnosed with a juvenile fibdroadenoma of the breast. The patient presented at age 18 with primary amenorrhea. She had been raised as a female and went through thelarche at age 13 and adrenarche at age 14. She had two sisters and three maternal aunts with androgen insensitivity syndrome. Physical exam revealed that the patient had no cervix, and a pelvic sonogram confirmed that the uterus was absent. Genetic analysis revealed a 46 XY karyotype. Bilateral intra-abdominal testes were noted on ultrasound and subsequently removed. She was placed on synthetic estrogen replacement therapy. Roughly 1 year following orchiectomy, the patient noticed an enlarging mass in her right breast. Physical exam revealed a roughly 5 cm mobile mass in the upper portion of the nipple-areolar complex. Ultrasound showed a solid mass consistent with a fibroadenoma. Because of the size of the lesion and the patient's hormonal make-up, a fine needle aspirate was obtained. Cytopathology showed large cohesive sheets of ductal epithelial cells, scattered histiocytes, numerous bare nuclei, fragments of fibrous tissue and metachromatic stroma. Some of the stroma was noted to be cellular. The tumor was subsequently excised. Microscopically, the lesion had epithelial and stromal hyperplasia consistent with a fibroadenoma. Phyllodes-like qualities of large size, increased stromal cellularity, and intracanalicular growth ("leaf-like projections") were noted; however, the pathologist found that the florid epithelial hyperplasia and the patient's young age were more compatible with a juvenile fibroadenoma. We describe what we believe to be the first report of a patient with CAIS and a fibroadenoma of the breast. The hormonal imbalance typically found in these patients, combined with the fact that most individuals with CAIS receive exogenous estrogen therapy, suggests that there may be a relatively high incidence of fibroadenoma in these patients. [source] Canadian economic geography at the millenniumTHE CANADIAN GEOGRAPHER/LE GEOGRAPHE CANADIEN, Issue 1 2000TREVOR J. BARNES Over the last quarter of a century the Canadian economy experienced a series of profound changes which have affected every level of society. They include new forms of flexible production, fundamental changes in regulation at all spatial scales, structural shifts away from manufacturing towards service sector activities, the rise of information technology (IT) and computerization at the workplace, the feminization of the labour market, and, what has become the leitmotif of the age, globalization. Such changes are intimately connected with geography. By that we mean not merely that they take on a geographical form, but that geography is pan of their very constitution. In this sense Canadian economic geographers are exactly in the right time and the right place to make use of their skills. Indeed, over the last five years there has been an explosion of literature by Canadian economic geographers on precisely these kinds of changes that are simultaneously both economic and geographical. In reviewing that literature the paper begins by situating Canada within its wider global setting, which we then follow by surveying the diverse writing around the three broad sectors that make-up the Canadian economy: the resource sector, the manufacturing sector, and the service sector. We conclude by highlighting two particular research themes within Canadian economic geography that have become especially germane over the late 1990s. The first is on new labour markets and forms of work both of which have been transformed during the last decade; and the second is on new forms of industrial innovation, which are clearly pivotal to the future well-being of the country for the next millennium. Au cours des vingt-cinq dernières années, l'économie canadienne a connu une série, de changements profonds qui ont affecté toutes les couches de la société. Ces changements comprennent les nouvelles formes de production flexible, les changements fondamentaux dans la réglementation à toutes les échelles spatiales, la mutation structurelle du secteur industriel au secteur tertiaire, la montée de la technologie de l'information (Tl) et l'informatisation sur le lieu de travail, la présence plus importante des femmes sur le marché du travail, et, ce qui est devenu le leitmotiv de notre époque, la mondialisation. De tels changements sont intimement liés à la geographie. Par la, nous ne disons pas simplement qu'ils prennent une forme géographique, mais que la géographie fait partie intégrante de leur constitution. Dans ce sens, les géographes-économistes canadiens arrivent, si l'on peut dire, au bon endroit au bon moment pour mettre leurs connaissances à profit. En effet, on assiste depuis les cinq dernières années à une recrudescence impressionnante des travaux de géographes-économistes canadiens portant, précisément, sur ces types de changements qui sont à la fois économiques et géographiques. En faisant le compte-rendu de cette littérature scientifique, cet article situe d'abord le Canada dans son contexte mondial plus large, passe ensuite en revue ce qui a étéécrit au sujet des trois grands secteurs qui forment l'économie canadienne: les secteurs primaire, secondaire et tertiaire. Nous concluons en mettant en relief deux thèmes de recherches de la géographie économique canadienne qui sont devenus particulièrement pertinents depuis la fin des années 1990. Le premier traite des nouveaux marchés du travail et des nouvelles formes de travail, qui ont tous deux subi des transformations au cours de la dernière décennie. Le second traite des nouvelles formes d'innovation industrielle, qui sont cruciales pour le bien-être futur du pays à l'aube du nouveau millénaire. [source] |
