Selected AbstractsManagement Strategies and Improvement of Performance of Sewer NetworksCOMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING, Issue 7 2007Denys Breysse Even when they are conscious about the needs of maintenance to keep the system in a good condition, they lack efficient methods and tools that may help them in taking appropriate decisions. One can say that no really satisfactory and efficient tool exists, enabling the optimization of Inspection, Maintenance, or Rehabilitation (IMR) strategies on such systems. Sewer managers and researchers have been involved for many years in the French National Research Project for Renewal of Non Man Entry Sewer System (RERAU,Réhabilitation des Réseaux d'Assainissement Urbains, in French) to improve their knowledge of these systems and the management policies. During the RERAU project, a specific action has been dedicated to the modeling of asset ageing and maintenance. A special attention has been dedicated to the description of defects and dysfunctions, to the evaluation of performances and its modeling, accounting for its various dimensions (from the point of view of the manager, of the user, of the environment,). After having defined an Index of Technical Performance (ITp), we will introduce the Index of Technical and Economic Performance (ITEp) that is a combined measure of performance (including social costs) and technical costs. This index provides an objective standard tool for managers to compare different alternatives. It is used in the article to compare some simple IMR strategies. It sets the basis of a new method for no-man entry sewer system management, enabling us to analyze the profitableness of investment in terms of both technical and economic performance. [source] Bridging the theory-and-practice gap: Mediator power in practiceCONFLICT RESOLUTION QUARTERLY, Issue 4 2009Arghavan Gerami Although mediators are assumed to be neutral third parties, effective fulfillment of their role involves exercising a significant amount of authority and power. Mediators employ a range of approaches, orientations, and strategies. This article reviews some of the scholarship in this area. It then examines the various dimensions of mediator power, looking specifically at (1) the nature of mediator power and (2) its exercise of power through knowledge and expertise, through designing and controlling the process through reframing, and through imposing pressure to settle. Finally, the article discusses "ethical mediation" in light of mediator power. [source] GUARDIANSHIP IN CONTEXT: IMPLICATIONS FOR BURGLARY VICTIMIZATION RISK AND PREVENTION,CRIMINOLOGY, Issue 4 2007PAMELA WILCOX Survey data from 4,227 Seattle residents nested within 100 "neighborhoods" (census tracts) were analyzed to discern interrelationships between various dimensions of individual-level and neighborhood-level guardianship. We focused on four dimensions of guardianship,physical (target hardening), personal (home occupancy), social (informal control), and natural (surveillance through environmental design),at both individual and neighborhood levels. A multilevel opportunity, theoretical framework guided hypotheses, which suggests that each of the four dimensions of individual guardianship would be related more negatively to burglary as each of the four dimensions of aggregate guardianship increased. Multilevel logistic regression analysis revealed support for many of such hypothesized moderating effects of aggregate guardianship. More specifically, 6 of the 16 possible interaction effects were statistically significant at the .05 level and an additional 3 interaction effects were significant at the .10 level. In particular, individuallevel target hardening, place management, and natural surveillancewere related more negatively to burglary as neighborhood-level target hardening increased, as neighborhood-level informal social control increased, and as neighborhood-level natural surveillance increased. [source] Changes in perfectionism following cognitive-behavioral treatment for social phobia,DEPRESSION AND ANXIETY, Issue 3 2007Andrea Ashbaugh M.A. Abstract Previous studies have found that social phobia (social anxiety disorder) is associated with elevated levels of perfectionism, particularly concerns over making mistakes (CM) and doubts about actions (DA). This study investigated the extent to which various dimensions of perfectionism change as a result of participating in a 12-session cognitive-behavioral group treatment for social phobia. One hundred seven individuals completed the Frost Multidimensional Perfectionism Scale before and after treatment. Participants improved on several measures of social anxiety, generalized anxiety, and depression. With respect to perfectionism, significant reductions were seen on total perfectionism scores and scores on particular dimensions (CM, DA, organization), but not on other dimensions (personal standards, parental expectations, parental criticism). Furthermore, changes in DA and to some extent CM predicted posttreatment levels of social anxiety after controlling for pretreatment levels of social anxiety and changes in anxiety and depression. Implications of these findings are discussed. Depression and Anxiety 24:169,177, 2007. © 2006 Wiley-Liss, Inc. [source] Predicting life-time and regular cannabis use during adolescence; the roles of temperament and peer substance use: the TRAILS studyADDICTION, Issue 4 2010Hanneke E. Creemers ABSTRACT Aims The aim of the present study was to determine the mediating role of affiliation with cannabis-using peers in the pathways from various dimensions of temperament to life-time cannabis use, and to determine if these associations also contributed to the development of regular cannabis use. Methods Objectives were studied using data from 1300 participants of the Tracking Adolescents' Individual Lives Survey (TRAILS), a large, general population study of Dutch adolescents. We used parent-reports on the Early Adolescent Temperament Questionnaire to assess the dimensions of high-intensity pleasure, shyness, fearfulness, frustration and effortful control at age 10,12 years. By means of self-reports, life-time and regular cannabis use were determined at age 15,18 years, and proportion of substance-using peers was determined at ages 12,15 and 15,18 years. Models were adjusted for age, sex, intelligence and parental cannabis use. Results High-intensity pleasure [odds ratio (OR) = 1.09, 95% confidence interval (CI) = 1.05,1.13] and effortful control (OR = 0.92, 95% CI = 0.89,0.96) affected the risk for life-time cannabis use through their influence on affiliation with cannabis-using peers. Shyness affected this risk independently from peer cannabis use. Only the pathway from effortful control was associated additionally with the development of regular cannabis use (OR = 0.93, 95% CI = 0.89,0.98). Conclusions Peer cannabis use and, to a lesser extent, certain temperamental characteristics affect an adolescent's risk of cannabis use, and should be considered in prevention programmes. We recommend future research to focus upon factors that potentially modify the association between temperament, affiliation with cannabis-using peers and cannabis use. [source] The dark triad: Facilitating a short-term mating strategy in menEUROPEAN JOURNAL OF PERSONALITY, Issue 1 2009Peter K. Jonason Abstract This survey (N,=,224) found that characteristics collectively known as the Dark Triad (i.e. narcissism, psychopathy and Machiavellianism) were correlated with various dimensions of short-term mating but not long-term mating. The link between the Dark Triad and short-term mating was stronger for men than for women. The Dark Triad partially mediated the sex difference in short-term mating behaviour. Findings are consistent with a view that the Dark Triad facilitates an exploitative, short-term mating strategy in men. Possible implications, including that Dark Triad traits represent a bundle of individual differences that promote a reproductively adaptive strategy are discussed. Findings are discussed in the broad context of how an evolutionary approach to personality psychology can enhance our understanding of individual differences. Copyright © 2008 John Wiley & Sons, Ltd. [source] Problems of Democratic Accountability in Network and Multilevel GovernanceEUROPEAN LAW JOURNAL, Issue 4 2007Yannis Papadopoulos Such processes are usually analysed under the angle of their efficiency, while their impact on the quality of democracy is neglected. This article first defines the concepts of multilevel governance and accountability, and then identifies the various dimensions of the latter. It further argues that MLG generates novel forms of accountability, but undermines its democratic dimension mainly for the following reasons: the weak visibility of MLG networks, their selective composition and the prevalence of peer over public forms of accountability. [source] Assessing horizontal equity in medication treatment among elderly Mexicans: which socioeconomic determinants matter most?HEALTH ECONOMICS, Issue 10 2008Jürgen Maurer Abstract Many low- and middle-income countries are currently undergoing a dramatic epidemiological transition, with an increasing disease burden due to degenerative noncommunicable diseases. Inexpensive medication treatment often represents a cost-effective means to prevent, control or cure many of these health conditions. Using micro-data from the 2001 Mexican Health and Aging Study, we assess horizontal inequity in medication treatment among older Mexicans before the introduction of Popular Health Insurance in Mexico. In doing so, we investigate the role of various dimensions of socioeconomic status for obtaining indicated medication treatment within a comparatively fragmented health-care system that features relatively high out-of-pocket expenditures. Our empirical analysis suggests health insurance coverage as a key socioeconomic determinant of indicated medication use with large and statistically significant positive effects on take-up. The effects of insurance status thereby clearly dominate any other possible effects of socioeconomic status on medication treatment. Our results thus highlight the importance of access to reliable health care and comprehensive coverage for rational medication use in the management of degenerative diseases. In light of this evidence, we expect that recent Mexican health-care reforms, which expand health insurance coverage to the previously uninsured population, will alleviate socioeconomic gradients in medication treatment among older people in need.

[source] ,By papers and pens, you can only do so much': views about accountability and human resource management from Indian government health administrators and workersINTERNATIONAL JOURNAL OF HEALTH PLANNING AND MANAGEMENT, Issue 3 2009Asha George Abstract Although accountability drives in the Indian health sector sporadically highlight egregious behaviour of individual health providers, accountability needs to be understood more broadly. From a managerial perspective, while accountability functions as a control mechanism that involves reviews and sanctions, it also has a constructive side that encourages learning from errors and discretion to support innovation. This points to social relationships: how formal rules and hierarchies combine with informal norms and processes and more fundamentally how power relations are negotiated. Drawing from this conceptual background and based on qualitative research, this article analyses the views of government primary health care administrators and workers from Koppal district, northern Karnataka, India. In particular, the article details how these actors view two management functions concerned with internal accountability: supervision and disciplinary action. A number of disjunctures are revealed. Although extensive information systems exist, they do not guide responsiveness or planning. While supportive supervision efforts are acknowledged and practiced, implicit quid-pro-quo bargains that justify poor service delivery performance are more prevalent. Despite the enactment of numerous disciplinary measures, little discipline is observed. These disjunctures reflect nuanced and layered relationships between health administrators and workers, as well as how power is negotiated through corruption and elected representatives within the broader political economy context of health systems in northern Karnataka, India. These various dimensions of accountability need to be addressed if it is to be used more equitably and effectively. Copyright © 2009 John Wiley & Sons, Ltd. [source] Motion picture performance: A review and research agendaINTERNATIONAL JOURNAL OF MANAGEMENT REVIEWS, Issue 3 2009Allègre L. Hadida This paper provides a comprehensive literature review of empirical studies of motion picture performance published from 1977 to 2006 inclusive in the following five disciplines of the social sciences: strategy, organization theory, marketing, cultural economics and sociology. It introduces a novel framework which organizes the various dimensions and explanatory factors of movie performance into five distinct categories and underscores their relationships. The paper, which uses this model as a roadmap for discussions of film success, serves two complementary purposes. First, it clarifies the current state of the literature, stresses core contributions and exposes limitations in existing research by emphasizing hitherto neglected independent explanatory factors, dependent dimensions and correlations between them. Second, it introduces five conceptual, methodological and empirical suggestions for further cinema performance research aimed at addressing these limitations and, accordingly, at providing better accounts of motion picture performance in view of the fast-changing conditions of cinema production, marketing and consumption. [source] Simulations of Xe@C60 collisions with graphitic filmsINTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY, Issue 15 2008Victor V. Albert Abstract Collisions between Xe@C60 and sheets of graphite of various dimensions were simulated. A Tersoff many-body potential modeled the interactions between carbon atoms and a Lennard-Jones potential simulated the xenon-carbon interactions. The simulations were compared to experiment and with simulations which implemented other potentials. The results indicate that a relatively small graphite film can be an accurate approximation for a nearly infinite sheet of graphite. © 2008 Wiley Periodicals, Inc.

Ditto Abstract Aim, Evolutionary theory predicts that levels of genetic variation in island populations will be positively correlated with island area and negatively correlated with island isolation. These patterns have been empirically established for oceanic islands, but little is known about the determinants of variation on habitat islands. The goals of this study were twofold. Our first aim was to test whether published patterns of genetic variation in mammals occurring on montane habitat islands in the American Southwest conformed to expectations based on evolutionary theory. The second aim of this research was to develop simple heuristic models to predict changes in genetic variation that may occur in these populations as a result of reductions in available mountaintop habitat in response to global warming. Location, Habitat islands of conifer forest on mountaintops in the American Southwest. Methods, Relationships between island area and isolation with measures of allozyme variation in four species of small mammal, namely the least chipmunk (Tamias minimus), Colorado chipmunk (Tamias quadrivittatus), red squirrel (Tamiasciurus hudsonicus), and Mexican woodrat (Neotoma mexicana), were determined using correlation and regression techniques. Significant relationships between island area and genetic variation were used to develop three distinct statistical models with which to predict changes in genetic variation following reduction in insular habitat area arising from global warming. Results, Patterns of genetic variation in each species conformed to evolutionary predictions. In general, island area was the most important determinant of heterozygosity, while island isolation was the most important determinant of polymorphism and allelic diversity. The heuristic models predicted widespread reductions in genetic variation, the extent of which depended on the population and model considered. Main conclusions, The results support a generalized pattern of genetic variation for any species with an insular distribution, with reduced variation in smaller, more isolated populations. We predict widespread reductions in genetic variation in isolated populations of montane small mammals in the American Southwest as a result of global warming. We conclude that climate-induced reductions in the various dimensions of genetic variation may increase the probability of population extinction in both the short and long term. [source] Family quality of life among families with a member who has an intellectual disability: an exploratory examination of key domains and dimensions of the revised FQOL SurveyJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 6 2009S. Werner Abstract Background The Family Quality of Life Survey (FQOLS-2006) was developed as the result of increased interest in family quality of life (FQOL) among families with a member who has an intellectual disability (ID). The instrument includes nine life domains and six dimensions reflecting the main areas and characteristics of FQOL. The aim of the current study was to provide a descriptive analysis of the domains and dimensions of the survey and to explore their relationship to one another and to global satisfaction. Method A convenience sample of 35 participants with a family member who had ID completed the FQOLS-2006 in a large urban centre in Canada. The data were analysed using descriptive analyses. Results The findings showed that although participants differentiated between different domains and dimensions, as reflected in their variability, stability was also found. For example, support from others was rated lowest across most dimensions, while family relationships and health of the family were generally rated higher. Conclusions The findings strengthen the importance of examining both the overall perception of FQOL as well as the perceptions in individual life domains. Moreover, they highlight the need to examine each life domain according to its various dimensions. In sum, the results call for further examination of the FQOLS-2006 as a useful tool for assessing FQOL and for implementing services based on it. [source] Uncounted or illusory blessings?JOURNAL OF INTERNATIONAL DEVELOPMENT, Issue 4 2007Competing responses to the Easterlin, Easterbrook, Schwartz paradoxes of well-being Abstract The Easterlin paradox concerns slight or negligible increases in personal satisfaction reported as income rises beyond high middle income levels. Sister paradoxes highlighted by Easterbrook and Schwartz concern the frequent low or negligible impact on personal satisfaction of improvements in various dimensions of life. The paper identifies a range of responses to the paradoxes, shows how these responses reflect a series of different conceptions of the meaning of well-being, and assesses their cogency. It indicates areas where follow-on research is required. Copyright © 2007 John Wiley & Sons, Ltd. [source] Fluoride ion diffusion from a glass,ionomer cementJOURNAL OF ORAL REHABILITATION, Issue 7 2000S.-Y. Lee The aims of this study were to observe the release of fluoride ions (F,) from GC-Fuji Lining-LC® glass,ionomer cement, to assess the diffusion process, and to measure fluoride diffusivity (D) in the set cement. Specimens of various dimensions and shapes, ranging from discs to cylindrical rods, were fabricated for both open and embedded modes of testing. In the open mode studies, specimens with different surface to volume ratios were selected and immersed in 37 °C distilled water. In the embedded mode studies, only one diametral surface of the rod-shaped specimens of different lengths and diameters was exposed. F, concentration was measured using a fluoride electrode. The storage solution was analysed at predetermined intervals hourly, daily, and weekly (up to 10 weeks). Immediately after each sampling, the old storage solution was discarded and replaced with new distilled water. F, release from the set cements was detectable (0·4,3·8 ppm, varied with sample geometry), even after a 10-week sampling interval. F, release was greater in ground set cements (0.37 ppm/mg powder) than in control samples of unmixed powder (0.01 ppm/mg powder) immersed for 1 h. Two mechanisms for F, release were proposed. One was short-term and involved rapid dissolution from the cement surface. The other was more gradual and resulted in the sustained diffusion of ions through the bulk cement, which can be modelled by applying a mathematical technique known as separation of variables to Fick's Second Law of Diffusion. The mean D of F, in embedded set cements of glass,ionomer was (1·4±0·5)×10,11 cm2/s, with higher apparent D observed in open mode samples [(7·6±1·4)×10,11 cm2/s]. [source] Behavioral and Biological Indicators of Impulsivity in the Development of Alcohol Use, Problems, and DisordersALCOHOLISM, Issue 8 2010C.W. Lejuez Alcohol use disorders (AUDs) are a devastating public health problem. The construct of impulsivity is biologically based and heritable, and its various dimensions are relevant for understanding alcohol use. The goal of the current manuscript is to review recent behavioral and biological research examining various dimensions of impulsivity and their relation to AUDs from risk for initial use through dependence and relapse. Moreover, we also highlight key psychological variables including affective processes as they relate to current use and early indications of alcohol problems, as well as psychopathology, violence, and aggression in relation to AUDs. Each section includes a critical summary and we conclude the review with future directions focused on issues relevant to measurement, causality, and intervention. Throughout the review, we attempt to be as specific as possible about the dimensions of impulsivity being referenced, while attempting to draw parallels and highlighting differences as the existing literature allows. [source] Environment,Flexibility Coalignment and Performance: An Analysis in Large versus Small FirmsJOURNAL OF SMALL BUSINESS MANAGEMENT, Issue 3 2006Antonio J. Verdú-Jover This paper takes a wide-ranging transnational look, within the frame of he European Union, at the differences between large and small firms based on practices of flexibility. More specifically, the research aims to evaluate whether small firms form a homogeneous body in applying flexible practices as opposed to large firms, as well as observing the differential effects on performance when there are discrepancies in the coalignment levels between a firm's actual flexibility and that required by the environment. The hypotheses are tested using data from 417 European firms. The results reveal that (1) good coalignments between actual and required flexibility (flexibility fit) have a greater influence on business performance in the case of small firms; (2) there are significant differences between small and large firms as regards operative flexibility, strategic flexibility, financial flexibility (organizational slack), and performance. The large firms analyzed coalign their flexibility fit better in their various dimensions (structural, operative, and strategic); (3) the degree of metaflexibility can be greater among small firms, which represents a greater information processing capacity, thus enabling the flexibility fit to be constantly coaligned to changes in the environment. However, a greater metaflexibility is not immediately reflected in the flexibility fit; and (4) this greater flexibility fit among large firms can be favored by their greater financial flexibility. [source] Nerve conduits and growth factor delivery in peripheral nerve repairJOURNAL OF THE PERIPHERAL NERVOUS SYSTEM, Issue 2 2007Lukas A. Pfister Abstract Peripheral nerves possess the capacity of self-regeneration after traumatic injury. Transected peripheral nerves can be bridged by direct surgical coaptation of the two nerve stumps or by interposing autografts or biological (veins) or synthetic nerve conduits (NC). NC are tubular structures that guide the regenerating axons to the distal nerve stump. Early synthetic NC have primarily been made of silicone because of the relative flexibility and biocompatibility of this material and because medical-grade silicone tubes were readily available in various dimensions. Nowadays, NC are preferably made of biodegradable materials such as collagen, aliphatic polyesters, or polyurethanes. Although NC assist in guiding regenerating nerves, satisfactory functional restoration of severed nerves may further require exogenous growth factors. Therefore, authors have proposed NC with integrated delivery systems for growth factors or growth factor,producing cells. This article reviews the most important designs of NC with integrated delivery systems for localized release of growth factors. The various systems discussed comprise NC with growth factors being released from various types of matrices, from transplanted cells (Schwann cells or mesenchymal stem cells), or through genetic modification of cells naturally present at the site of injured tissue. Acellular delivery systems for growth factors include the NC wall itself, biodegradable microspheres seeded onto the internal surface of the NC wall, or matrices that are filled into the lumen of the NC and immobilize the growth factors through physical-chemical interactions or specific ligand-receptor interactions. A very promising and elegant system appears to be longitudinally aligned fibers inserted in the lumen of a NC that deliver the growth factors and provide additional guidance for Schwann cells and axons. This review also attempts to appreciate the most promising approaches and emphasize the importance of growth factor delivery kinetics. [source] National Culture and Industrial Relations and Pay StructuresLABOUR, Issue 2 2001Boyd Black The paper develops an explanatory model of comparative industrial relations and labour market structures based on national culture. The four cultural variables derived by Hofstede (Culture's Consequences, Beverly Hills: Sage, 1984) are used to investigate the relationship between national culture and various dimensions of industrial relations and pay structures. The paper finds national culture to be associated with the centralization of bargaining, the extent of corporatism, the degree of co-ordination in bargaining, the coverage of collective bargaining, trade union density, the extent of worker participation in decision making, and most dimensions of the pay structure. Hofstede's MAS variable, measuring cultural values representing gender social structuring, is associated with both industrial relations institutions and the pay structure. The results provide support for our cultural model. [source] Earth Impact Effects Program: A Web-based computer program for calculating the regional environmental consequences of a meteoroid impact on EarthMETEORITICS & PLANETARY SCIENCE, Issue 6 2005Gareth S. COLLINS This paper details the observations, assumptions and equations upon which the program is based. It describes our approach to quantifying the principal impact processes that might affect the people, buildings, and landscape in the vicinity of an impact event and discusses the uncertainty in our predictions. The program requires six inputs: impactor diameter, impactor density, impact velocity before atmospheric entry, impact angle, the distance from the impact at which the environmental effects are to be calculated, and the target type (sedimentary rock, crystalline rock, or a water layer above rock). The program includes novel algorithms for estimating the fate of the impactor during atmospheric traverse, the thermal radiation emitted by the impact-generated vapor plume (fireball), and the intensity of seismic shaking. The program also approximates various dimensions of the impact crater and ejecta deposit, as well as estimating the severity of the air blast in both crater-forming and airburst impacts. We illustrate the utility of our program by examining the predicted environmental consequences across the United States of hypothetical impact scenarios occurring in Los Angeles. We find that the most wide-reaching environmental consequence is seismic shaking: both ejecta deposit thickness and air-blast pressure decay much more rapidly with distance than with seismic ground motion. Close to the impact site the most devastating effect is from thermal radiation; however, the curvature of the Earth implies that distant localities are shielded from direct thermal radiation because the fireball is below the horizon. [source] The development of the School Function Assessment , Chinese version for cross-cultural use in TaiwanOCCUPATIONAL THERAPY INTERNATIONAL, Issue 1 2004Jeng-Liang Hwang Abstract The primary purpose of this research project was to translate and adapt the School Function Assessment (SFA), a standardized criterion-referenced instrument that measures school-related functional skills, for its cross-cultural use in Taiwan. The project consisted of four study phases: translation, cultural adaptation, pilot testing, and field testing for standardization. A series of rigorous procedures including the method of translation and back-translation, team consensus for cultural adaptation, and Rasch modelling techniques were used to address various dimensions of cross-cultural equivalence and psychometric properties of the translated SFA. The protocols that were developed as well as technical issues that were addressed in this project provide useful guidelines for international occupational therapists who are interested in translating and adapting instruments for cross-cultural use.

[source] Brightness enhancement of ITO/GaN LEDs by self-aligned micro-net structuresPHYSICA STATUS SOLIDI (C) - CURRENT TOPICS IN SOLID STATE PHYSICS, Issue 7 2005Kow-Ming Chang Abstract Arrays of square and hexagonal holes of various dimensions were patterned on indium-tin-oxide (ITO)/GaN light-emitting diodes (LEDs) using the self-aligned method to increase the light extraction area and shorten the optical paths. The hole region was etched to give the sidewall of the active layer a sloped profile, and it was passivated by SiOxNy films to extract more light. The self-aligned micro-net LED is at least 10% brighter than the conventional structure in the normal direction without loss of operating voltage or leakage current. The ratio of luminescence to total output power is increased by 25% at a current density of 100 A/cm2. Moreover, varying the hole dimensions and the designed density increased the peak external quantum efficiency by 5% at a current of 3 mA. The greater axial luminescence and the higher external quantum efficiency make LEDs self-aligned micro-net structures quite useful in surface-mounting and low-power-consuming devices, such as cellular phones.

KGaA, Weinheim) [source] The End of the Fertility Transition in the Developed WorldPOPULATION AND DEVELOPMENT REVIEW, Issue 3 2002John Bongaarts By the late 1990s the average period total fertility rate in the developed world had declined to 1.6, a level substantially lower than projected in the 1970s and 1980s. This article examines recent trends and patterns in fertility in the developed world with particular emphasis on the effects and implications of changes in the timing of childbearing. The main objective is to demonstrate that while fertility in these countries is indeed low, women's childbearing levels are not as low as period measures such as the total fertility rate suggest. To obtain a full understanding of the various dimensions of fertility change. several indicators are examined, including period and cohort fertility by birth order and childbearing preferences. An analysis of these indicators demonstrates that period fertility measures in many developed countries are temporarily depressed by a rise in the mean age at childbearing. The distortion of the TFR is as great as 0.4 births per woman in Italy and Spain. These effects have been present in many developed countries since the 1970s and could continue for years into the future. But tempo effects are temporary, and once the postponement of childbearing ends,as it eventually must,the corresponding fertility-depressing effect stops, thus putting upward pressure on period fertility. Countries with very low fertility and substantial tempo effects may well experience rises in fertility in the near future if the timing of childbearing stabilizes. Even if this happens, however, it seems unlikely that fertility will rebound to the replacement level. [source] THE IMPACT OF PUBLIC SERVICE MOTIVES ON WORK OUTCOMES IN AUSTRALIA: A COMPARATIVE MULTI-DIMENSIONAL ANALYSISPUBLIC ADMINISTRATION, Issue 4 2007JEANNETTE TAYLORArticle first published online: 12 OCT 200 There is a general consensus that individuals who are driven to serve the public interest can possess a mix of public service motives for engaging in altruistic actions. This article proposes that when analysed simultaneously, some public service motives may play a more important role than others in influencing work outcomes. The pressing questions are which ones and how? Through a survey of a group of Australian public sector employees, this article explores the relationship between the various dimensions of public service motivation (PSM) and the common work outcomes: organizational commitment, job satisfaction and job motivation. The combinations of PSM dimensions that had a greater impact on these work outcomes are also found to vary with different outcomes. [source] Determinants of quality of life in patients with cancerCANCER, Issue 5 2005A South American study Abstract BACKGROUND Because health-related quality of life (QOL) is an important outcome in cancer management, the authors sought to better understand its determinants. To address this subject, they analyzed QOL, as measured with the Functional Assessment of Cancer Therapy-General questionnaire (FACT-G), Spanish Version 4, and depicted the complex relations among physical, psychological, social, and cultural factors, including spirituality. METHODS A cross-sectional study design was used with a sample of 309 patients with cancer. The influence of several possible determinants was first studied by univariate regression analysis. Variables showing an association were included in a forward stepwise multivariate regression model. RESULTS Five regression models were studied, for the FACT-G total score and its four subscales. Five variables explained 32.1% of the variance of the FACT-G total score: tumor stage, spiritual well-being, income, mood disorders, and mode of questionnaire administration. The type and relevance of the explanatory variables differed among the various dimensions of QOL. CONCLUSIONS The authors underlined the entwining of biologic, psychosocial, and spiritual factors as determinants of the QOL of patients with cancer, thus supporting the multidimensional definition and modeling of the construct.
