Frequency characteristics of flexibly vibration discrete-continuous mechatronic system

PROCEEDINGS IN APPLIED MATHEMATICS & MECHANICS, Issue 1 2008
A. BuchaczArticle first published online: 26 FEB 200
The purpose of this paper is formulating of problem of flexibly vibrating mechatronic system. The main approach of the subject was to formulate the problem in the form of set of differential equation of motion and state equation of considered mechatronic model of object. The considered flexibly vibrating mechanical system is a continuous beam, clamped at one of its end. Integral part of mechatronic system is a transducer, extorted by harmonic voltage. In the paper the linear mechanical subsystem and linear electric subsystem of mechatronic system has been considered. The methods of analysis and obtained results can be base on design and investigation for this type of mechatronic systems. The mechatronic system formed from mechanical and electric subsystems with electromechanical bondage has been considered. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source]


Cell death in normal and abnormal development

CONGENITAL ANOMALIES, Issue 1 2008
Philip E. Mirkes
ABSTRACT Research over the past 50 years has consistently documented that cell death is an integral part of both normal development and the etiology of birth defects; however, the significance of this cell death has been, until recently, unclear. Research published during the past 15 years has now shown that programmed cell death (PCD) and teratogen-induced cell death are genetically controlled processes (apoptosis) that play important roles in both normal and abnormal development. Therefore, the purpose of this review is to highlight what is known about PCD and teratogen-induced cell death and their relationships to the mechanisms of apoptosis and abnormal development.

Corporate Governance of Banks in Developing Economies: concepts and issues

CORPORATE GOVERNANCE, Issue 3 2004
T. G. Arun
This paper discusses the corporate governance of banking institutions in developing economies. This is an important issue given the essential role that banks play in the financial systems of developing economies and the widespread banking reforms that these economies have implemented. Based on a theoretical discussion of the corporate governance of banks, we suggest that banking reforms can only be fully implemented once a prudential regulatory system is in place. An integral part of banking reforms in developing economies is the privatisation of banks. We suggest that corporate governance reforms may be a prerequisite for the successful divestiture of government ownership. Furthermore, we also suggest that the increased competition resulting from the entrance of foreign banks may improve the corporate governance of developing-economy banks. [source]


Physiological functions of glucose-inhibited neurones

ACTA PHYSIOLOGICA, Issue 1 2009
D. Burdakov
Abstract Glucose-inhibited neurones are an integral part of neurocircuits regulating cognitive arousal, body weight and vital adaptive behaviours. Their firing is directly suppressed by extracellular glucose through poorly understood signalling cascades culminating in opening of post-synaptic K+ or possibly Cl, channels. In mammalian brains, two groups of glucose-inhibited neurones are best understood at present: neurones of the hypothalamic arcuate nucleus (ARC) that express peptide transmitters NPY and agouti-related peptide (AgRP) and neurones of the lateral hypothalamus (LH) that express peptide transmitters orexins/hypocretins. The activity of ARC NPY/AgRP neurones promotes food intake and suppresses energy expenditure, and their destruction causes a severe reduction in food intake and body weight. The physiological actions of ARC NPY/AgRP cells are mediated by projections to numerous hypothalamic areas, as well as extrahypothalamic sites such as the thalamus and ventral tegmental area. Orexin/hypocretin neurones of the LH are critical for normal wakefulness, energy expenditure and reward-seeking, and their destruction causes narcolepsy. Orexin actions are mediated by highly widespread central projections to virtually all brain areas except the cerebellum, including monosynaptic innervation of the cerebral cortex and autonomic pre-ganglionic neurones. There, orexins act on two specific G-protein-coupled receptors generally linked to neuronal excitation. In addition to sensing physiological changes in sugar levels, the firing of both NPY/AgRP and orexin neurones is inhibited by the ,satiety' hormone leptin and stimulated by the ,hunger' hormone ghrelin. Glucose-inhibited neurones are thus well placed to coordinate diverse brain states and behaviours based on energy levels. [source]


Moral Education Between Hope and Hopelessness: The Legacy of Janusz Korczak

CURRICULUM INQUIRY, Issue 1 2008
SARA EFRAT EFRON
ABSTRACT The responsibility for addressing morality and moral education in the current moral climate is a daunting task for conscientious educators. What educational response can extricate us from the debilitating feelings of hopelessness and helplessness as we are confronted by horrific terrorist actions, controversial use of military might, displays of corruption and greed and a growing general tension and anxiety? At this demoralizing juncture of uncertainty and doubt, the figure of Janusz Korczak (1878,1942), a Jewish-Polish educator, looms large. For more than 30 years, Korczak devoted his life to educating orphaned Jewish and non-Jewish children. He stayed with the Jewish children to the end as they all perished in a concentration camp. At a time when the surrounding society surrendered to fascism, anti-Semitism, and self-destruction, Korczak encouraged individual autonomy and caring relationships within the context of a community where a vision of justice and trust was an integral part of life. The orphanages he directed were democratic, self-ruled communities, where the children had their own parliament, court, and newspaper. This article describes the principles and the actualization of Korczak's moral education and explores how Korczak reconciled the differences between the ethical world he created in his institutions and the surrounding immoral society. The example set by Korczak's educational praxis serves as an inspiring model of school life across the boundaries of time and place and touches our need to believe in education's responsibility to strive and struggle for a better world, even when it seems an unattainable goal. And the hour shall come when a man will know himself, respect, and love. And the hour shall come in history's clock when man shall know the place of good, the place of evil, the place of pleasure, and the place of pain. (Korczak, 1978, p. 237) [source]


The art and science of oral examination

DERMATOLOGIC THERAPY, Issue 3 2010
Rania Agha
ABSTRACT Performing an accurate oral examination is an integral part of a complete dermatological evaluation. As dermatologists, we are frequently asked to assess and treat numerous oral pathologies, which include, but are not limited to, normal variants, infections, ulcers, granulomas, lymphomas, as well as primary and metastatic tumors of the mouth and lips. The oral mucosa can be the window through which one can see and make numerous systemic diagnoses. Some clinicians are apprehensive about performing this evaluation, or feel that this examination is outside of their realm of expertise. These concerns may reflect limited exposure and education during training. Therefore, this article aimed to educate the readers on how to complete an oral examination, demonstrate normal variants, and highlight potential pitfalls and limitations of performing oral biopsies.

The neurocognitive performance of drug-free and medicated euthymic bipolar patients do not differ

ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009
U. Goswami
Objective:, Although it is established that euthymic bipolar patients have neurocognitive deficits, the influence of medication on their cognitive performance is uncertain and requires investigation. Method:, Neuropsychological tests of executive function, memory and attention were performed on 44 prospectively verified, euthymic bipolar I patients, 22 of whom were drug-free. Residual mood symptom effects were controlled statistically using ancova. Results:, Drug-free and medicated patients differed only in delayed verbal recall (Rey AVLT list A7, drug-free > medicated), and perseverations during the five-point test (drug-free > medicated). When residual mood symptoms were controlled statistically, differences between drug-free and medicated subjects became insignificant. Medication effect sizes were modest. Significant correlations were found between residual depression scores and measures of verbal learning. Conclusion:, Medications did not have any significant influence on neurocognitive performance, suggesting that neurocognitive deficits are an integral part of bipolar disorder. [source]


The Construction of the Myth of Survival

DEVELOPMENT AND CHANGE, Issue 1 2007
Mercedes González de la Rocha
ABSTRACT A myth has come into being that the poor household/family is able to survive in spite of a lack of resources and the presence of macroeconomic policies that foster unemployment and poverty. It has an accompanying fable that tells of how the poor manage to implement survival strategies that are based on their endless capacity to work, to consume less and to be part of mutual help networks. This myth has become a useful tool for policy makers as they design more aggressive neoliberal economic adjustment policies. This contribution examines anthropological and sociological insights regarding the life of the poor and the organization of their households, in which women's paid and unpaid work is an integral part. Through the lens of a researcher in the field of urban poverty and household organization, the article re-examines the fable of the good survivor. Evidence debunks the myth, showing that the optimistic message of this fable does not match with the realities of the impact of economic change on women's lives. But the myth is sustained, as this more negative story is not one that supra-national policy actors want to hear. [source]


Decentralization and Democracy in Indonesia: A Critique of Neo-Institutionalist Perspectives

DEVELOPMENT AND CHANGE, Issue 4 2004
Vedi R. Hadiz
This article assesses some of the major premises of neo-institutionalist explanations of decentralization policy and practices, but focuses especially on the relationship between decentralization and democracy, in the context of the recent and ongoing Indonesian experience with decentralization. In the last two decades ,decentralization' has become, along with ,civil society', ,social capital' and ,good governance', an integral part of the contemporary neo-institutionalist lexicon, especially that part which is intended to draw greater attention to ,social' development. The concern of this article is to demystify how, as a policy objective, decentralization has come to embody a barely acknowledged political, not just theoretical, agenda. It also suggests alternative ways of understanding why decentralization has often failed to achieve its stated aims in terms of promoting democracy, ,good governance', and the like. What is offered is an understanding of decentralization processes that more fully incorporates the factors of power, struggle and interests, which tend to be overlooked by neo-institutionalist perspectives. The current Indonesian experience clearly illustrates the way in which institutions can be hijacked by a wide range of interests that may sideline those that champion the worldview of ,technocratic rationality'.

Psychosocial problems and seizure-related factors in children with epilepsy

DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 3 2006
B Hřie
In this study we describe psychosocial functions and seizurerelated factors in a population-based sample of children with epilepsy. Psychosocial problems (Achenbach scales), cognitive function, and socioeconomic status were studied in 117 children with epilepsy aged between 6 and 13 years (mean age 11y [SD 2y 1mo] and 10y 8mo [SD 2y]; 71 males, 46 females) and in randomly selected controls matched with 117 children for sex and age (mean age 11y 2mo [SD 2y 1mo] and 10y 5mo [SD 2y 4mo]; 69 males, 48 females). The children had partial (n=67), generalized (n=43), or undetermined (n=7) epilepsy syndromes, and partial (n=68), generalized (n=47), or other (n=2) main seizure types. Psychosocial problems were more common among children with epilepsy than controls (odds ratio 5,9) and significantly related to epilepsy syndrome, main seizure type, age at onset, and seizure frequency. Mothers and teachers reported males with epilepsy as having more problems than females. Females self-reported psychosocial problems, males did not. Psychosocial problems were common in childhood epilepsy. Females appreciated the problems more realistically than males. Psychosocial problems should be considered an integral part of epilepsy management. [source]


Drosophila neuropeptide F mediates integration of chemosensory stimulation and conditioning of the nervous system by food

DEVELOPMENTAL NEUROBIOLOGY, Issue 1 2001
Ping Shen
Abstract The conserved neuropeptide Y (NPY) signaling pathway has been strongly implicated in the stimulation of food uptake in vertebrates as well as in the regulation of food conditioned foraging behaviors of Caenorhabditis elegans. Using in situ RNA hybridization and immunocytochemistry, we report the neuronal network of Drosophila neuropeptide F (dNPF), a human NPY homologue, in the larval central nervous system and its food-dependent modifications. We provide indications that gustatory stimulation by sugar, but not its ingestion or metabolism, is sufficient to trigger long-term, dose-dependent alterations of the dNPF neuronal circuit through both dnpf activation and increased synaptic transmission. Our results strongly suggest that the dNPF neuronal circuit is an integral part of the sensory system that mediates food signaling, providing the neural basis for understanding how invertebrate NPY regulates food response. © 2001 John Wiley & Sons, Inc.

How can structured self-management patient education improve outcomes in people with type 2 diabetes?

DIABETES OBESITY & METABOLISM, Issue 1 2010
J. Jarvis
Type 2 diabetes (T2DM) is a long-term chronic condition that is complex to manage, with the majority of management being done by the person with diabetes outside of the clinical setting. Because of its complexities, effective self-management requires skills, confidence and the ability to make decisions and choices about treatments and lifestyle on a day-to-day basis. Equipping a person with these self-management skills is in itself challenging and it is now widely accepted that structured education is an integral part of the management of T2DM. This paper explores whether structured self-management education can improve outcomes in people with diabetes. The authors explore what self-management education is, why it is needed and then go on to examine the recent evidence from clinical trials from 2006 onwards. [source]


Intraoperative cytology,Role in bone lesions

DIAGNOSTIC CYTOPATHOLOGY, Issue 9 2010
Khaliqur Rahman M.D.
Abstract In spite of becoming an integral part of surgical pathology, very few reports are available regarding the utility of intraoperative cytology (IOC) exclusively for bone lesions. This study was undertaken in a view to fill this lacuna. Sixty bone lesions were evaluated intraoperatively with the help of cytology smears prepared by touch, scrape, or crush technique. The diagnosis made on cytological preparation was compared with histopathological diagnosis taking the latter as gold standard. Different parameters like reasons for Intraoperative consultation, best technique for preparation of smear, average time taken to render a diagnosis, and finally the accuracy of IOC was evaluated. Common reasons for the intraoperative consultation were to make or confirm a diagnosis for proper surgical intervention and to evaluate the surgical resection margin. Scrape was found to be the best method for cytological smear preparation. Average time taken to render a diagnosis was 20 minutes. Sensitivity, specificity, and overall diagnostic accuracy was 96.7, 96.6, and 96.6%, respectively. Cytology can play a valuable role in the intraoperative diagnosis of bone lesions. The method is simple, cheap, quick, and has no complication. It should be undertaken routinely, as a rapid intraoperative diagnosis will expedite timely and proper management of the patients, along with early post operative treatment and thus avoid the aggravating delays.

Vaccines, Viagra, and Vioxx: medicines, markets, and money,when life-saving meets life-style,

DRUG DEVELOPMENT RESEARCH, Issue 2 2005
David J. Triggle
Abstract In this Commentary, life-style drugs will be termed as "those drugs for which there is a definable and real, but limited, therapeutic need, but a need that has been significantly stimulated by the cycle of pharmaceutical company advertising and pressure and public demand." The key to the continuing expansion of the life-style drug market is a progressive narrowing of the definition of "normal" coupled with campaigns launched by the pharmaceutical industry that persuade both patients and clinicians that a major and treatable disease does exist and that drug treatment, rather than acceptance of hair loss or occasional lack of sexual interest, and so on, is both necessary and appropriate. The expansion of the market for prescription drugs in this manner is now an integral part of the business model of the pharmaceutical industry. For society, the expanding role of these drugs, particularly those directed at "desires rather than diseases," raises ethical issues of our increasing obsession with a medically directed quest for perfection, and financial issues of the cost of this quest on the health care system and its priorities. For the pharmaceutical industry, there are questions of whether its role is life-saving or life-styling for a Huxleyan "Brave New World." Drug Dev Res 64:90,98, 2005. © 2005 Wiley-Liss, Inc.

PLANNING THROUGH INCLUSIVE DIALOGUE: NO ESCAPE FROM SOCIAL CHOICE DILEMMAS

ECONOMIC AFFAIRS, Issue 4 2005
Tore Sager
The thrust of the theory of preference aggregation is that it is impossible to design institutions guaranteeing collective decisions that are both consistent and fair. Proponents of deliberative democracy have used this as an argument for decision-making based on dialogue rather than voting. Communicative public planning - producing plans through public participation exercises - is seen as an integral part of deliberative democracy. It is argued here, however, that the inclusive dialogue of this style of planning cannot promise escape from arbitrariness and does not necessarily deliver improved local decision-making. [source]


Nanowires for surface enlargement of narrow-bore fused-silica tubing

ELECTROPHORESIS, Issue 21-22 2004
Andreas Woldegiorgis
Abstract A method for preparation of silica nanowires with dimensions of d = 10,100 nm, l = 5,500 nm, is described. The nanostructured material is an integral part of the inner surface of narrow bore fused-silica capillary tubing. The wire preparation method is based on a decomposition of 2-chloro-1,1,2-trifluoroethyl methyl ether at elevated temperature and pressure. The silica bulk material is rearranged via a sustained silica-hydrogen fluoride chemistry, and reaction mechanisms for this process are proposed. The method is suitable for preparing long lengths of tubing with the modified surface. It is our belief that the texture of the capillary wall with its increased surface area is useful for applications such as microreactions, catalysis, and high-resolution pressure and/or electrodriven open-tubular liquid chromatography.

Customer Satisfaction in a Large Urban Fire Department Emergency Medical Services System

ACADEMIC EMERGENCY MEDICINE, Issue 1 2004
David E. Persse MD
Objectives: The purpose of this study was to determine if emergency medical services (EMS) customer satisfaction could be assessed using telephone-survey methods. The process by which customer satisfaction with the EMS service in a large, fire department,based EMS system is reported, and five month results are presented. Methods: Ten percent of all patients transported during the period of October 15, 2001, through March 15, 2002, were selected for study. In addition, during the same period, all EMS incidents in which a patient was not transported were identified for contact. Customer-service representatives contacted patients via telephone and surveyed them from prepared scripts. Results: A total of 88,528 EMS incidents occurred during the study period. Of these, 53,649 resulted in patient transports and 34,879 did not. Ten percent of patients transported (5,098) were selected for study participation, of which 2,498 were successfully contacted; of these, 2,368 (94.8%) reported overall satisfaction with the service provided. Of the 34,879 incidents without transport, only 5,859 involved patients who were seen but not transported. All of these patients were selected for study. Of these, 2,975 were successfully contacted, with 2,865 (96.3%) reporting overall satisfaction. The most common reason given for nonsatisfaction in both groups was the perception of a long response time. Conclusions: It is possible to conduct a survey of EMS customer satisfaction using telephone-survey methods. Although difficulties exist in contacting patients, useful information is made available with this method. Such surveys should be an integral part of any EMS system's quality-improvement efforts. In this survey, the overwhelming majority of patients, both transported and not transported, were satisfied with their encounter with EMS. [source]


Social control and coercion in addiction treatment: towards evidence-based policy and practice

ADDICTION, Issue 1 2006
T. Cameron Wild
ABSTRACT Background Social pressures are often an integral part of the process of seeking addiction treatment. However, scientists have not developed conclusive evidence on the processes, benefits and limitations of using legal, formal and informal social control tactics to inform policy makers, service providers and the public. This paper characterizes barriers to a robust interdisciplinary analysis of social control and coercion in addiction treatment and provides directions for future research. Approach Conceptual analysis and review of key studies and trends in the area are used to describe eight implicit assumptions underlying policy, practice and scholarship on this topic. Findings Many policies, programmes and researchers are guided by a simplistic behaviourist and health-service perspective on social controls that (a) overemphasizes the use of criminal justice systems to compel individuals into treatment and (b) fails to take into account provider, patient and public views. Conclusions Policies and programmes that expand addiction treatment options deserve support. However, drawing a firm distinction between social controls (objective use of social pressure) and coercion (client perceptions and decision-making processes) supports a parallel position that rejects treatment policies, programmes, and associated practices that create client perceptions of coercion.

Teaching forensic odontology: an opinion on its content and format,

EUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 3 2006
A. B. Acharya
Abstract, Forensic odontology involves dentists' participation in assisting legal and criminal issues. Formal teaching in forensic odontology has existed for over a 100 years. Over the last century, forensic odontology has evolved and, today, it is an integral part of undergraduate dental training in many countries. Dentists have been trained in the specialty, and dedicated departments established in institutes and universities around the world. A survey undertaken at five universities revealed that these centres have developed detailed curricula in forensic odontology, and a general standard exists in teaching forensic odontology, however, coverage of recent advances in forensic science may be lacking. While recognising that these programmes are not representative of teaching in forensic odontology worldwide, suggestions are made for an alternative approach to teaching the subject. Moreover, it is stressed that teaching be undertaken by qualified forensic odontologists. [source]


America's Health Care Safety Net Intact or Unraveling?

ACADEMIC EMERGENCY MEDICINE, Issue 11 2001
Lynne D. Richardson MD
Abstract In virtually every community in this nation, the emergency department (ED) is an integral part of the health care safety net, often serving as the only available point of access to the health care system for many vulnerable and disenfranchised individuals. The authors present a brief overview of the March 2000 report released by the Institute of Medicine that described and assessed the current status of the nation's health care safety net. The authors discuss the role of the ED as a safety net provider and as a window onto the status of the rest of the health care system. The authors describe the Andersen behavioral model of health services use and suggest it as a useful theoretical framework for emergency medicine researchers who are interested in studying these issues.

Application of stereology to dermatological research

EXPERIMENTAL DERMATOLOGY, Issue 12 2009
Sřren Kamp
Abstract:, Stereology is a set of mathematical and statistical tools to estimate three-dimensional (3-D) characteristics of objects from regular two-dimensional (2-D) sections. In medicine and biology, it can be used to estimate features such as cell volume, cell membrane surface area, total length of blood vessels per volume tissue and total number of cells. The unbiased quantification of these 3-D features allows for a better understanding of morphology in vivo compared with 2-D methods. This review provides an introduction to the field of stereology with specific emphasis on the application of stereology to dermatological research by supplying a short insight into the theoretical basis behind the technique and presenting previous dermatological studies in which stereology was an integral part. Both the theory supporting stereology and a practical approach in a dermatological setting are reviewed with the aim to provide the reader with the capability to better assess papers employing stereological estimators and to design stereological studies independently.

Isocitrate dehydrogenase of Plasmodium falciparum

FEBS JOURNAL, Issue 8 2003
Energy metabolism or redox control?
Erythrocytic stages of the malaria parasite Plasmodium falciparum rely on glycolysis for their energy supply and it is unclear whether they obtain energy via mitochondrial respiration albeit enzymes of the tricarboxylic acid (TCA) cycle appear to be expressed in these parasite stages. Isocitrate dehydrogenase (ICDH) is either an integral part of the mitochondrial TCA cycle or is involved in providing NADPH for reductive reactions in the cell. The gene encoding P. falciparum ICDH was cloned and analysis of the deduced amino-acid sequence revealed that it possesses a putative mitochondrial targeting sequence. The protein is very similar to NADP+ -dependent mitochondrial counterparts of higher eukaryotes but not Escherichia coli. Expression of full-length ICDH generated recombinant protein exclusively expressed in inclusion bodies but the removal of 27 N-terminal amino acids yielded appreciable amounts of soluble ICDH consistent with the prediction that these residues confer targeting of the native protein to the parasites' mitochondrion. Recombinant ICDH forms homodimers of 90 kDa and its activity is dependent on the bivalent metal ions Mg2+ or Mn2+ with apparent Km values of 13 µm and 22 µm, respectively. Plasmodium ICDH requires NADP+ as cofactor and no activity with NAD+ was detectable; the for NADP+ was found to be 90 µm and that of d -isocitrate was determined to be 40 µm. Incubation of P. falciparum under exogenous oxidative stress resulted in an up-regulation of ICDH mRNA and protein levels indicating that the enzyme is involved in mitochondrial redox control rather than energy metabolism of the parasites.

Realism, Prediction, and Foreign Policy

FOREIGN POLICY ANALYSIS, Issue 3 2009
Samuel Barkin
Attempts by some contemporary realists to both claim that international politics are objectively predictable and at the same time prescribe particular foreign policies cannot hold together logically, because they are internally contradictory. The core argument of this article is that these attempts not only fail to fulfill their goal, but that the attempt to be scientific, to see the world as predictable, is ontologically incompatible with the core insight of classical realism, that we must see the world as it is, rather than as we want it to be. There are two ramifications of this observation for a realism that is not internally contradictory. The first is that a prescriptive realism must be a theory of foreign policy, not a theory of systems structure. And the second is that a realism that works as a theory of foreign policy prediction needs to be reflexive, needs to examine its own assumptions and biases as an integral part of the process of studying international politics.

Functional interaction of intestinal CYP3A4 and P-glycoprotein

FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 6 2004
Kari T. Kivistö
Abstract Intestinal CYP3A4-mediated biotransformation and active efflux of absorbed drug by P-glycoprotein are major determinants of bioavailability of orally administered drugs. The hypothesis that CYP3A4 and P-glycoprotein may act in concert to limit oral drug bioavailability is attractive from a theoretical point of view. Evidence in support of such an interplay between CYP3A4 and P-glycoprotein comes mainly from a limited number of in vitro and animal studies. Obviously, it is a challenging task to demonstrate in vivo in humans that the function of CYP3A4 and P-glycoprotein in enterocytes is complementary, and results to directly support this concept remain elusive. However, CYP3A4 and P-glycoprotein are clearly an integral part of an intestinal defence system to protect the body against harmful xenobiotics, and drugs that are substrates of both proteins often have a low bioavailability after oral administration. The functional interaction of intestinal CYP3A4 and P-glycoprotein warrants additional study. Further understanding this interplay would be potentially useful during drug development to solve bioavailability problems of new drug entities. [source]


Does Gender Still Matter?

GENDER, WORK & ORGANISATION, Issue 4 2007
A Study of the Views of Women in the ICT Industry in New Zealand
Using data from in-depth interviews with female information and communication technology (ICT) professionals from New Zealand's four main cities, this article uses a social constructivist framework to investigate the women's perceptions of their ICT work place. The results show that there are regional differences in organization type, job category and salaries, as well as in the perceptions of the women towards their environment. Most women did not actively seek to be employed in ICT , rather their entry was serendipitous. While they enjoyed working in the environment, there was an obvious gendering of the workforce with most technical positions being held by men and women working mainly in the softer side of ICT. The women perceived their gendered roles to be a highly important and an integral part of ICT and believed their salaries were equitable with their male colleagues. Having a greater understanding of how women view their ICT work place will contribute to attracting and retaining them in an industry where a shortage of skills is envisaged in the near future.

,It's a public, I reckon': Publicness and a Suburban Shopping Mall in Sydney's Southwest

GEOGRAPHICAL RESEARCH, Issue 2 2010
ADAM TYNDALL
Abstract Traditionally, public space has been perceived as an integral part of fully functioning liberal democracy. Yet much research argues that public space is in decline due to regimes of neoliberal governance paralleled with a growth in quasi-public spaces such as shopping malls, casinos and gated communities. It is argued that these new spatial forms posit a commercialised, sanitised and ultimately exclusionary urban form in place of more egalitarian, engaging and ultimately democratic public spaces. Increasingly, however, urban research has questioned the veracity of the claims made about the nature of traditional public space as well as investigating the marginal and contingent nature of publicness as constituted by and enacted in a variety of places. Drawing on Foucault's concept of heterotopic space, this paper reports on a qualitative study based on focus group interviews conducted with users of a suburban shopping mall in Sydney's southwest. The research uncovers both a more complex and less overtly deterministic publicness than has previously been identified in such spaces. From these findings the paper argues for a conception of publicity which moves beyond the zero-sum game approach endemic in much work in this area to one which analyses the qualitative effect quasi-public spaces are having on the nature of publicness in the Australian context. The paper concludes by arguing that a rethinking of publicness allows room for the emergence of a more progressive public ethic. [source]


Optimal Policy for Financial Market Liberalizations: Decentralization and Capital Flow Reversals

GERMAN ECONOMIC REVIEW, Issue 1 2000
Theo S. Eicher
Financial market liberalizations are an integral part of economic development. While initial booms in investment and output are commonly seen as signs of successful deregulation, they often reverse at a later stage as international capital flows turn negative and economic growth slows markedly. Such reversals of fortunes have commonly been attributed to incorrect policies that supposedly followed the initial, appropriate measures. It is unclear, however, if capital flow reversals are actually the result of policy reversals, or if they occur as part of the normal transition when financial liberalization is accompanied by a single suboptimal policy. The later hypothesis has not been explored in the theoretical literature We construct a general equilibrium growth model of a small open economy, in which capital flow reversals are the result of a single, suboptimal policy imposed at the beginning of the financial liberalization. We show how improper taxation of foreign borrowing initially leads to strong growth fuelled by an investment boom and foreign borrowing. Still along the transition, however, the model predicts that capital flows must reverse endogenously at a later stage, as the debt burden rises and the country-specific risk premium increases. Our data on the Latin American and East Asian countries provide strong support for our hypothesis. [source]


Extramammary Paget's disease,a proliferation of adnexal origin?

HISTOPATHOLOGY, Issue 6 2006
S Regauer
Aim :,To investigate a possible follicular origin of extramammary Paget's disease (EPD). EPD is a predominantly intraepidermal tumour with extensive involvement of adnexal structures and high recurrence rates suggesting a follicular stem cell origin. Cytokeratin (CK) 15 and CK19 are considered markers for follicular stem cells located in the hair follicle bulge region. Methods and results :,Formalin-fixed paraffin-embedded tissues of 12 cases of primary EPD (three anal, nine vulvar) were studied immunohistochemically with antibodies to CK15 and CK19. All cases of EPD showed polygonal Paget cells in the interfollicular epidermis, hair follicles, sebaceous and apocrine glands distributed individually, in nests and in gland-like areas. The polygonal Paget cells were intimately associated with small, flat, mitotically active, ,compressed' keratinocytes. The large Paget cells uniformly expressed CK19 in 12/12 EPD. The small ,compressed' keratinocytes showed strong cytoplasmic CK15 staining in 9/12 EPD with focal accentuation, while the polygonal Paget cells were negative. Conclusions :,These histological and immunohistochemical observations allow the following conclusions: (i) the small, flat, ,compressed' keratinocytes are an integral part of EPD; (ii) the dual cell population is reminiscent of sebaceous glands with mature sebocytes and germinative keratinocytes; (iii) since both cell types express cytokeratins typical for follicular differentiation, EPD may be a proliferation of adnexal stem cells residing in the infundibulo-sebaceous unit of hair follicles and adnexal structures.

The evolving classification of soft tissue tumours: an update based on the new WHO classification

HISTOPATHOLOGY, Issue 1 2006

Tumour classifications have become an integral part of modern oncology and, for pathologists, they provide guidelines which facilitate diagnostic and prognostic reproducibility. In many organ systems and most especially over the past decade or so, the World Health Organization (WHO) classifications have become pre-eminent, partly enabled by the timely publication of new ,blue books' which now incorporate detailed text and copious illustrations. The new WHO classification of soft tissue tumours was introduced in late 2002 and, because it represents a broad consensus view, it has gained widespread acceptance. This review summarizes the changes, both major and minor, which were introduced and briefly describes the significant number of tumour types which have been first recognized or properly characterized during the past decade. Arguably the four most significant conceptual advances have been: (i) the formal recognition that morphologically benign lesions (such as cutaneous fibrous histiocytoma) may very rarely metastasize; (ii) the general acceptance that most pleomorphic sarcomas can be meaningfully subclassified and that so-called malignant fibrous histiocytoma is not a definable entity, but instead represents a wastebasket of undifferentiated pleomorphic sarcomas, accounting for no more than 5% of adult soft tissue sarcomas; (iii) the acknowledgement that most lesions formerly known as haemangiopericytoma show no evidence of pericytic differentiation and, instead, are fibroblastic in nature and form a morphological continuum with solitary fibrous tumour; and (iv) the increasing appreciation that not only do we not know from which cell type(s) most soft tissue tumours originate (histogenesis) but, for many, we do not recognize their line of differentiation or lineage,hence an increasing number of tumours ar placed in the ,uncertain differentiation' category.
