Selected AbstractsESCAPING CRIME: THE EFFECTS OF DIRECT AND INDIRECT VICTIMIZATION ON MOVING,CRIMINOLOGY, Issue 4 2008MIN XIE This article investigates the impact of criminal victimization on household residential mobility. Existing research finds that direct experiences with crime influence mobility decisions, such that persons who suffer offenses near their homes are more likely to move. The current study extends this line of inquiry to consider whether indirect victimization that involves neighbors also stimulates moving. The analysis uses the National Crime Survey to estimate multilevel models that incorporate data from individual households and their spatially proximate neighbors. The results show that the link between direct victimization and moving continues to hold after controlling for neighborhood context. Indirect property victimization also leads to moving, with effects about equal in size to those of direct victimization. In contrast, no evidence is found that violent victimization that occurs in neighboring homes influences mobility, probably because most of these events are nonstranger violence that provokes less anxiety for neighbors. [source] The Business of Caring: Women's Self-Employment and the Marketization of CareGENDER, WORK & ORGANISATION, Issue 4 2010Nickela Anderson Our goal in this article is to contribute to a differentiated analysis of paid caring work by considering whether and how women's experiences of such work is shaped by their employment status (for example, self-employed versus employee) and the nature of care provided (direct or indirect). Self-employed care workers have not been widely studied compared with other types of care workers, such as employees providing domestic or childcare in private firms or private homes. Yet their experiences may be quite distinct. Existing research suggests that self-employed workers earn less than employees and are often excluded from employment protection. Nonetheless, they often report greater autonomy and job satisfaction in their day-to-day work. Understanding more about the experiences of self-employed caregivers is thus important for enriching existing theory, research and policy on the marketization of care. Addressing this gap, our article explores the working conditions, pay and levels of satisfaction of care workers who are self-employed. We draw on interviews from a small-scale study of Canadian women engaged in providing direct care (for example, childcare) and indirect care (for example, cleaning). [source] Moonlighting in a High Growth Economy: Evidence from U.S. State-Level DataGROWTH AND CHANGE, Issue 4 2002Mark Partridge Despite the prevalence of multiple jobholding, there is relatively little research into its causes. Existing research has tested the predictions of standard labor models with micro data. Yet, there has been virtually no research into the relationship between moonlighting and structural differences in regional labor markets such as wages and employment growth. In this manner, this study examines the large differences in multiple jobholding rates across U.S. states. The findings indicate that multiple jobholding acts as a short-term shock absorber to cyclical changes. However, in the long-term, these effects dissipate, indicating that moonlighting plays a similar role as do changes in unemployment and labor-force participation to regional labor market shocks. Conversely, multiple jobholding rates are inversely related to average weekly earnings. Thus, job growth accompanied by real wage (and productivity) growth may result in a decline in multiple jobholding, further exacerbating potential labor shortages. Other key factors found to influence multiple jobholding include occupational structure and education. [source] Do Analysts and Auditors Use Information in Accruals?JOURNAL OF ACCOUNTING RESEARCH, Issue 1 2001Mark T. Bradshaw Existing research indicates that firms with high accruals are more likely to experience future earnings problems, but that investors' expectations, as reflected in stock prices, do not appear to anticipate these problems. In this paper, we directly examine the published opinions of two types of professional investor intermediaries to see if they provide investors with information concerning the future earnings problems experienced by firms with high accruals. First, we examine the earnings forecasts of sell-side analysts. We show that analysts' earnings forecasts do not incorporate the predictable future earnings declines associated with high accruals. Second, we examine the behavior of independent auditors. We find no evidence that auditors signal the future earnings problems associated with high accruals through either their audit opinions or through auditor changes. Overall, our evidence indicates that analysts and auditors do not alert investors to the future earnings problems associated with high accruals, thus corroborating previous findings that investors do not appear to anticipate these problems. [source] The role and design of screen images in software documentationJOURNAL OF COMPUTER ASSISTED LEARNING, Issue 4 2000H. Van der Meij Abstract, Software documentation for the novice user typically must try to achieve at least three goals: to support basic knowledge and skills development; to prevent or support the handling of mistakes, and to support the joint handling of manual, input device and screen. This paper concentrates on the latter goal. Novice users often experience split-attention problem due to the need to (almost) simultaneously attend to different media. Existing research indicates that split-attention problems can be prevented or reduced by the presence of screen images in the manual. Research is yet unclear about the optimal design of these pictures. This study examines three design styles. Forty-eight novice users received one of the three manual based on these styles. The manuals were an introduction to Windows 95. The users of the most successful manual needed 25% less training time and had a 60% better retention. The most important characteristics of the design style of this manual were its use of full screen images (instead of partial ones) and a two-column lay-out in which the instructions and screen images were presented side-by-side in a left-to-right reading order. The discussion focuses on the tension that exists between theory and practice. Special attention is given to the contributions of a taxonomy of screen images and cognitive load theory. [source] Parasites and deleterious mutations: interactions influencing the evolutionary maintenance of sexJOURNAL OF EVOLUTIONARY BIOLOGY, Issue 5 2010A. W. PARK Abstract The restrictive assumptions associated with purely genetic and purely ecological mechanisms suggest that neither of the two forces, in isolation, can offer a general explanation for the evolutionary maintenance of sex. Consequently, attention has turned to pluralistic models (i.e. models that apply both ecological and genetic mechanisms). Existing research has shown that combining mutation accumulation and parasitism allows restrictive assumptions about genetic and parasite parameter values to be relaxed while still predicting the maintenance of sex. However, several empirical studies have shown that deleterious mutations and parasitism can reduce fitness to a greater extent than would be expected if the two acted independently. We show how interactions between these genetic and ecological forces can completely reverse predictions about the evolution of reproductive modes. Moreover, we demonstrate that synergistic interactions between infection and deleterious mutations can render sex evolutionarily stable even when there is antagonistic epistasis among deleterious mutations, thereby widening the conditions for the evolutionary maintenance of sex. [source] Long-term illness and patterns of medicine taking: are people with schizophrenia a unique group?JOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 3 2001G. R. Marland rmn dipn bed (hons) mn pgcrm rnt Patients with schizophrenia relapse because of inadequate levels of medicine taking. Therefore, it seems logical to learn about the factors underpinning their medicine-taking decisions. Further research is urgently needed to explore this area and thereby to refine models of practice, to promote therapeutic interactions with medicine. Existing research tends to share three common deficits. ,It is grounded in the worldview of the psychiatrist not the patient. ,It studies the influence of symptoms on compliance behaviour in isolation from other potential variables. ,It overlooks the potential influence of the chronicity experience in general by examining schizophrenia outwith the context of other enduring illnesses. Overall these deficits may combine to distort the influence of schizophrenic symptoms on medicine decision making and justify a coercive rather than an empowering approach. A pernicious self-fulfilling spiral may be contributing to the problem of relapse in schizophrenia. Potentially the mental health nurse has a role in addressing this problem. [source] Research Note: The Influence of the Press in Shaping Public Opinion towards the European Union in BritainPOLITICAL STUDIES, Issue 3 2004Sean Carey Existing research finds that European citizens evaluate the EU according to the perceived costs and benefits of integration. Instead of assuming that cue-givers provide an informational role in this process, we investigate the direct effects of positive and negative EU messages from prominent cue-givers, including political parties and the media. Using the 2001 British Election Study, we examine the impact of the main political parties and newspapers on public attitudes towards membership of the EU and the prospect of joining the single European currency. During the 2001 British General Election campaign, the media and the main political parties had small independent effects on attitudes towards EU membership and the potential adoption of the single European currency. When voters receive the same messages from both their party and their newspaper, these effects are considerable. [source] Parent-Adolescent Violence and Later Behavioral Health Problems Among Homeless and Housed YouthAMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 3 2009Mason G. Haber PhD Parent-adolescent violence (i.e., violence between parents and adolescents) is an important pathway to homelessness and predicts poor behavioral health outcomes among youth. However, few studies have examined links between parent violence and outcomes among youth who are homeless. Existing research has also tended to ignore adolescent violence toward parents, despite evidence that mutual violence is common. The current study examines prospective links of parent-adolescent violence to outcomes among youth who were homeless and demographically matched youth, through two complementary substudies: (a) an exploratory factor analysis (EFA) of items measuring parent and adolescent violence combined in the same analysis; and (b) an examination of predictive relationships between the factors identified in the EFA and behavioral health problems, including mental health and alcohol abuse problems. Predictive relationships were examined in the overall sample and by gender, ethnic, and housing status subgroups. Results of the EFA suggested that parent-adolescent violence includes intraindividual (i.e., separate parent and adolescent) physical components and a shared psychological component. Each of these components contributed uniquely to predicting later youth behavioral health. Implications for research and practice with youth who are homeless are discussed. [source] A Framework for Determining the Influence of the Corporate Board of Directors in Accounting StudiesCORPORATE GOVERNANCE, Issue 1 2001Karen Cravens Accounting, auditing, and tax professionals constantly evaluate the integrity, competence, and financial performance of clients as factors in practice that influence both client acceptance decisions and the manner in which professional services are rendered. Yet, from an accounting perspective, previous research investigating the corporate board of directors as a governance mechanism has focused only on the representational role of board members. Moreover, many of these studies resulted in conflicting findings according to these attributes. Other disciplines address the particular influence of the board with respect to overall corporate performance, but arrive at little agreement on either the effect of or the most critical of board attributes. This literature review synthesizes the existing research to provide a framework in which to evaluate the effect of the board of directors in accounting settings and, in particular, when conducting future research that employs elements of corporate governance as dependent or independent variables in accounting studies. [source] Phylogenetic beta diversity: linking ecological and evolutionary processes across space in timeECOLOGY LETTERS, Issue 12 2008Catherine H. Graham Abstract A key challenge in ecological research is to integrate data from different scales to evaluate the ecological and evolutionary mechanisms that influence current patterns of biological diversity. We build on recent attempts to incorporate phylogenetic information into traditional diversity analyses and on existing research on beta diversity and phylogenetic community ecology. Phylogenetic beta diversity (phylobetadiversity) measures the phylogenetic distance among communities and as such allows us to connect local processes, such as biotic interactions and environmental filtering, with more regional processes including trait evolution and speciation. When combined with traditional measures of beta diversity, environmental gradient analyses or ecological niche modelling, phylobetadiversity can provide significant and novel insights into the mechanisms underlying current patterns of biological diversity. [source] How Opportunities Develop in Social EntrepreneurshipENTREPRENEURSHIP THEORY AND PRACTICE, Issue 4 2010Patricia Doyle Corner The purpose of this article was to extend existing research on opportunity identification in the social entrepreneurship literature through empirically examining this phenomenon. We used an inductive, theory-building design that surfaced patterns in social value creation across multiple case studies. The patterns showed actors seeing a social need and prospecting ideas that could address it. Data also revealed multiple, not individual, actors, dynamically engaged in interactions that nudged an opportunity into manifestation. Also, data suggested complementarities to effectuation and rational/economic processes that are divergent theoretical approaches to the study of entrepreneurship to date. [source] Policy implications of the widespread practice of ,pre-drinking' or ,pre-gaming' before going to public drinking establishments,are current prevention strategies backfiring?ADDICTION, Issue 1 2009Samantha Wells ABSTRACT Aim To describe the research, policy and prevention implications of pre-drinking or pre-gaming; that is, planned heavy drinking prior to going to a public drinking establishment. Methods The authors describe the phenomenon of pre-drinking, motivations for pre-drinking and its associated risks using available research literature, media and popular internet vehicles. Results Heavy drinking prior to going out has emerged as a common and celebrated practice among young adults around the world. Apparent motivations are: (i) to avoid paying for high priced drinks at commercial drinking establishments; (ii) to achieve drunkenness and enhance and extend the night out; and (iii) to socialize with friends, reduce social anxiety or enhance male group bonding before going out. Limited existing research on pre-drinking suggests that it is associated with heavy drinking and harmful consequences. We argue that policies focused upon reducing drinking in licensed premises may have the unintended consequence of displacing drinking to pre-drinking environments, possibly resulting in greater harms. Conclusions Effective policy and prevention for drinking in licensed premises requires a comprehensive approach that takes into account the entire drinking occasion (not just drinking that occurs in the licensed environment), as well as the ,determined drunkenness' goal of some young people. [source] Differential impact of state tobacco control policies among race and ethnic groupsADDICTION, Issue 2007John A. Tauras ABSTRACT Aims This paper describes patterns of racial and ethnic cigarette use in the United States and discusses changes in state-level tobacco control policies. Moreover, this paper reviews the existing econometric literature on racial and ethnic smoking and discusses the limitations of that research. Finally, this paper outlines an agenda for future research. Methods Patterns of racial and ethnic smoking and changes in state-level tobacco control policies in the United States were obtained from a variety of sources, including surveys and government and private documents and databases. After an extensive literature search was completed, the existing research was scrutinized and recommendations for much-needed future research were put forth. Findings Despite the fact that certain racial and ethnic minorities bear a disproportionate share of the overall health burden of tobacco, less than a handful of econometric studies have examined the effects of state-level public policies on racial and ethnic smoking. The existing literature finds Hispanics and African Americans to be more responsive to changes in cigarette prices than whites. Only one study examined other state-level tobacco policies. The findings from that study implied that adolescent white male smoking was responsive to changes in smoke-free air laws, while adolescent black smoking was responsive to changes in youth access laws. Conclusions While much has been learned from prior econometric studies on racial and ethnic smoking in the United States, the existing literature suffers from numerous limitations that should be addressed in future research. Additional research that focuses on races and ethnicities other than white, black and Hispanic is warranted. Furthermore, future studies should use more recent data, hold sentiment toward tobacco constant and control for a comprehensive set of tobacco policies that take into account not only the presence of the laws, but also the level of restrictiveness of each policy. [source] Foster Family Characteristics and Behavioral and Emotional Problems of Foster Children: A Narrative Review,FAMILY RELATIONS, Issue 1 2001John G. Orme The purpose of this article is to review the literature on the foster family characteristics that are thought to contribute to the behavioral and emotional problems of foster children. The review is shaped by an understanding of the personal and familial factors associated with children's problem behaviors in the general population. These factors include parenting, the family home environment, family functioning, marital functioning, family demography, child temperament, parents' mental health, and social support. Limitations within the existing research on these foster family characteristics are noted, and suggestions for future research are provided. [source] Experimental Evidence of the Knowledge Gap: Message Arousal, Motivation, and Time DelayHUMAN COMMUNICATION RESEARCH, Issue 4 2008Maria Elizabeth Grabe This study experimentally tested the knowledge gap from an information processing perspective. Specifically, knowledge acquisition was investigated under conditions of medium and low news message arousal, with time delay. Results show the persistence of a knowledge gap, particularly for low arousing messages. In fact, at low levels of message arousal, the gap is larger than at medium levels of arousal. Some existing research suggests that message salience explains the knowledge gap. Findings from this study show that information processing aptitude may also be a significant factor. Measures of several dimensions of participant motivation to cognitively engage with news messages were added as covariates to statistical analyses. These were found not to affect the knowledge gap outcomes in this data set. Résumé Des preuves expérimentales de l,écart des savoirs : intérêt des messages, motivation et décalage de temps Cette étude a testé expérimentalement l'écart des savoirs à partir d,une perspective du traitement de l'information. En particulier, l,acquisition des connaissances fut étudiée dans des conditions d'intérêt moyen et faible des messages d,information, avec un décalage de temps. Les résultats démontrent la persistance d'un écart des savoirs, particulièrement pour les messages à faible intérêt. En fait, l,écart est plus large à de faibles niveaux d'intérêt qu,à des niveaux moyens. Des recherches préalables suggèrent que la prépondérance des messages explique l'écart des savoirs. Les résultats de cette étude démontrent que les aptitudes de traitement de l,information peuvent aussi être un facteur important. Les mesures de plusieurs dimensions de la motivation des participants à s'impliquer cognitivement avec les messages informatifs furent ajoutées comme covariables aux analyses statistiques.

Insbesondere wurde die Wissensaneignung bei Nachrichten unter Bedingungen eines mittleren und niedrigen Botschaftserregungsniveaus mit Zeitverzögerung untersucht. Die Ergebnisse zeigen das Fortdauern einer Wissenskluft insbesondere bei wenig erregenden Botschaften. Tatsächlich ist die Kluft bei einem geringen Niveau der Botschaftserregung größer als bei mittleren Erregungsniveaus. Bestehende Forschung legt nahe, dass die Wissenskluft durch die Botschaftssalienz erklärt werden kann. Die Ergebnisse dieser Studie zeigen, dass die Informationsverarbeitungsfähigkeit ebenfalls ein signifikanter Faktor sein könnte. Messungen verschiedenen Dimensionen der Motivation der Teilnehmer, sich kognitiv mit den Nachrichtenbotschaften zu beschäftigen, wurden als Kovariate in die statistische Analyse einbezogen. Diese zeigten keine Auswirkungen auf die Wissenskluft in dieser Stichprobe. Resumen La Evidencia Experimental de la Brecha de Conocimiento: La Excitación del Mensaje, la Motivación, y la Demora de Tiempo Este estudio puso a prueba experimental la brecha de conocimiento desde la perspectiva del procesamiento de la información. Específicamente, la adquisición de conocimiento fue investigada bajo condiciones de excitación mediana y baja a los mensajes de noticias, con una demora de tiempo. Los resultados muestran la persistencia de la brecha de conocimiento, particularmente en los mensajes de excitación baja. De hecho, en los niveles de excitación de mensaje bajos la brecha fue mayor que en los niveles de excitación medianos. Algunas investigaciones existentes sugieren que la notabilidad del mensaje explica la brecha de conocimiento. Los hallazgos de este estudio muestran que la aptitud de procesamiento de información puede ser un factor significante también. Las medidas de varias dimensiones de la motivación del participante para involucrarse cognitivamente con los mensajes de noticias fueron agregadas como covarianzas a los análisis estadísticos. Se encontró que éstos no afectaron los resultados de la brecha de conocimiento en este grupo de datos.

ZhaiYao Yo yak [source] IT project managers' construction of successful project management practice: a repertory grid investigationINFORMATION SYSTEMS JOURNAL, Issue 3 2009Nannette P. Napier Abstract Although effective project management is critical to the success of information technology (IT) projects, little empirical research has investigated skill requirements for IT project managers (PMs). This study addressed this gap by asking 19 practicing IT PMs to describe the skills that successful IT PMs exhibit. A semi-structured interview method known as the repertory grid (RepGrid) technique was used to elicit these skills. Nine skill categories emerged: client management, communication, general management, leadership, personal integrity, planning and control, problem solving, systems development and team development. Our study complements existing research by providing a richer understanding of several skills that were narrowly defined (client management, planning and control, and problem solving) and by introducing two new skill categories that had not been previously discussed (personal integrity and team development). Analysis of the individual RepGrids revealed four distinct ways in which study participants combined skill categories to form archetypes of effective IT PMs. We describe these four IT PM archetypes , General Manager, Problem Solver, Client Representative and Balanced Manager , and discuss how this knowledge can be useful for practitioners, researchers and educators. The paper concludes with suggestions for future research. [source] Consumer evaluation of net utility: Effects of competition on consumer brand selection processesJAPANESE PSYCHOLOGICAL RESEARCH, Issue 4 2001Michel Laroche This study explores how brand-related information is integrated within a competitive environment. Specifically, we develop a structural equation model of competition between two brands, which includes each brand's price-quality characteristics (i.e., net utility). The model simultaneously tests how the net utility of the focal and competing brands affects consumers' attitudes, intentions, and choice regarding the focal brand. This study extends existing research with the findings that price-quality evaluations of a focal brand and net utility perceptions of competing brands influence consumers' attitudes, intentions, and choice regarding the focal brand. Thus, in order to attract consumers to their brands, marketers should focus not only on improving the performance and net utility of their own brands, but also on studying competing brands in the marketplace. [source] State-of-the-Art in Longitudinal Studies on Aging: An Overview of the SupplementJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 2010Ruth M. Tappen RN The articles in this supplement are based on a conference held in January 2008 sponsored by a grant from the Robert Wood Johnson Foundation. The purpose of the conference was to summarize major findings and methodological issues in previous and ongoing longitudinal studies on aging and to identify potentially fruitful areas for future research. This article is a review and synthesis of the articles in this supplement. Each of the articles makes important contributions to summarizing existing research, identifying challenging methodological issues, or proposing areas that should be explored in future research. Three themes were identified: general improvement in the health status of the population aged 65 and older in the United States, a shift in longitudinal research on aging from a focus on the endpoints of disease to a focus on the preclinical stage and underlying mechanisms of these diseases, and contemporary developments in longitudinal research methodology. A number of practical suggestions were also drawn from the articles reviewed. [source] Aggression towards health care staff in a UK general hospital: variation among professions and departmentsJOURNAL OF CLINICAL NURSING, Issue 1 2004Sue Winstanley BSc Background., Aggression towards health care staff is an increasing problem and although many studies have examined psychiatric settings, few have considered general hospitals and in particular, variation among professions and locations. In addition, studies often fail to include all forms of aggression such as threatening behaviour and verbal aggression. Methods., This study extends existing research by evaluating physical assault, threatening behaviour and verbal aggression from patients/visitors towards general hospital staff in the context of different professions and departments. Results and conclusions., The survey of staff showed that aggression is widespread. Within the preceding year, 27% of the respondents were assaulted, 23% experienced threatening behaviour from patients and 15.5% experienced threatening behaviour from visitors. Over 68% reported verbal aggression, 25.7% experiencing it more regularly than monthly. By departments, over 42% of the medical department staff, 36% of the surgical staff and over 30% of the Accident and Emergency staff were assaulted. By profession, staff nurses and enrolled nurses reported the most assaults (43.4%) and doctors, the fewest (13.8%). Other nursing grades and health care professions all reported levels of physical assault in excess of 20%. Correspondingly high levels of threatening behaviour and verbal aggression were also reported although the patterns of victimization differed according to the various professions and departments. Independently, significant levels of assault, threatening behaviour and verbal aggression were reported. When aggregated they demonstrate the higher levels of victimization that general hospital staff experienced on a regular basis. Relevance to clinical practice., Institutional averages actually obscure the much higher levels of aggression experienced by the particular professions in particular departments. This study helps to localize the problem and identify those at most risk, but more research is needed into the aetiology of the aggression and of vulnerability factors associated with victimization. [source] Helpseeking behavior among Filipino Americans: A cultural analysis of face and languageJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 5 2003Fang Gong In this study we explore the existing research on Asian Americans and helpseeking behavior, focusing primarily on Filipino Americans and the cultural variables of face and language. Although some important and specific cultural factors have been hypothesized to affect the helpseeking behaviors of ethnic minorities, very few empirical studies have been conducted to specifically test these hypotheses. To fill the gaps in previous research, we examined the influence of concern with face and of language abilities on helpseeking behavior for mental health problems among Filipino Americans. In addition, to obtain a more comprehensive understanding of helpseeking behavior, we divided the mental health care systems into four categories: lay, mental health specialty, general practitioner, and folk systems. Data are from the Filipino American Epidemiological Study (FACES) survey. The main statistical method we employed was logistic regression. Results from the descriptive analyses reveal that the lay system is the most frequently used source of care compared with the other systems of professional and folk systems for Filipino Americans. Furthermore, findings from the main effects models suggest that face and language are important cultural factors that contribute to the helpseeking behavior of Filipino Americans, but they have different influences on the four types of mental health care systems. The interaction analyses indicate that concern with face interacts with language abilities when predicting use of the lay system and the general medical sector. Despite these findings, to fully understand the dynamics of helpseeking, other cultural factors and longitudinal studies are needed. © 2003 Wiley Periodicals, Inc. J Comm Psychol 31: 469,488, 2003. [source] The Role of Feelings in Investor Decision-MakingJOURNAL OF ECONOMIC SURVEYS, Issue 2 2005Brian M. Lucey Abstract., This paper surveys the research on the influence of investor feelings on equity pricing and also develops a theoretical basis with which to understand the emerging findings of this area. The theoretical basis is developed with reference to research in the fields of economic psychology and decision-making. Recent advancements in understanding how feelings affect the general decision-making of individuals, especially under conditions of risk and uncertainty [e.g. Loewenstein et al. (2001). Psychological Bulletin 127: 267,286], are covered by the review. The theoretical basis is applied to analyze the existing research on investor feelings [e.g. Kamstra et al. (2000). American Economic Review (forthcoming); Hirshleifer and Shumway (2003). Journal of Finance 58 (3): 1009,1032]. This research can be broadly described as investigating whether variations in feelings that are widely experienced by people influence investor decision-making and, consequently, lead to predictable patterns in equity pricing. The paper concludes by suggesting a number of directions for future empirical and theoretical research. [source] Social goals and conflict strategies of individuals with mild to moderate intellectual disabilities who present problems of aggressionJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 5 2008C. Pert Abstract Background A few recent studies have adopted a social cognitive perspective to explore how individuals with intellectual disabilities (IDs), who present problems of aggression, view their social world. The focus has mainly been on participants' perceptions of others' behaviour within conflict situations. The present exploratory study aims to compliment existing research by exploring social cognitive factors that may influence how individuals respond to conflict. Methods Study was carried out with 20 aggressive and 20 non-aggressive men and women who have a mild to moderate ID. The ,Social Goals and Strategies for Conflict' (SGASC) assessment was devised to explore whether group or gender differences could be found in participants' expected outcomes of aggressive strategies, their expected outcomes of submissive strategies and their emotional reaction to these outcomes. Participants' social goals within hypothetical situations of conflict were also explored. Results It was found that aggressive and non-aggressive participants have different social goals. There were no significant differences for expected outcomes of aggression or submissiveness. Nevertheless, a number of trends suggest that more aggressive participants expect negative outcomes for submissiveness compared with their non-aggressive peers. Conclusions While the findings of this study are tentative, investigating the social outcomes that are valued by individuals with ID who present problems of aggression appears to be a promising area for further research, with possible implications for clinical assessment and treatment. [source] Finding the Person in Personal RelationshipsJOURNAL OF PERSONALITY, Issue 6 2002Harry T. Reis ABSTRACT The search for dispositional factors that influence the course and conduct of close relationships has long and popular roots. No cogent theory of interpersonal processes would deny that dispositional factors matter, and, furthermore, both scholarly and lay analyses often emphasize them. Although existing research has made progress in understanding how dispositions affect behavior in ongoing relationships, when all is said and done, this progress has been modest. In this paper, we discuss several interlocking theoretical and methodological principles that may facilitate movement to the next (and more sophisticated) generation of theory and research. We draw particularly on interdependence theory to discuss the concepts of relationship and persons-in-relationship. Central to our analysis is the principle that interaction in relationships is an inherently dynamic, temporal, and thoroughly interdependent process that cannot be properly understood from examination of the static, global dispositions of one of its members. To provide grounding for our analysis, we also discuss several specific implications of these concepts for the conduct of research seeking to understand personality in relationships. [source] TRENDS IN NEIGHBORHOOD INCOME INEQUALITY IN THE U.S.: 1980,2000,JOURNAL OF REGIONAL SCIENCE, Issue 5 2008Christopher H. Wheeler ABSTRACT This paper reports evidence on the geographic pattern of income inequality, both within and between neighborhoods, across a sample of 359 U.S. metropolitan areas between 1980 and 2000. The results indicate that overall income inequality within a metro area tends to be driven by variation within neighborhoods, not between them, although we find that between-neighborhood differences rose dramatically during the 1980s and subsided somewhat during the 1990s. While this trend is similar to what existing research has found, our findings reveal potentially important differences in the magnitudes of the changes depending on whether neighborhoods are defined by block groups or tracts. [source] Housing and Mental Health: A Review of the Evidence and a Methodological and Conceptual CritiqueJOURNAL OF SOCIAL ISSUES, Issue 3 2003Gary W. Evans Despite the fact that people invest more financial, temporal, and psychological resources in their homes than in any other material entity, research on housing and mental health is remarkably underdeveloped. We critically review existing research on housing and mental health, considering housing type (e.g., single-family detached versus multiple dwelling), floor level, and housing quality (e.g., structural damage). We then discuss methodological and conceptual shortcomings of this literature and provide a theoretical framework for future research on housing quality and mental health. [source] Consistent database sampling as a database prototyping approachJOURNAL OF SOFTWARE MAINTENANCE AND EVOLUTION: RESEARCH AND PRACTICE, Issue 6 2002Jesús Bisbal Abstract Requirements elicitation has been reported to be the stage of software development when errors have the most expensive consequences. Users usually find it difficult to articulate a consistent and complete set of requirements at the beginning of a development project. Prototyping is considered a powerful technique to ease this problem by exposing a partial implementation of the software system to the user, who can then identify required modifications. When prototyping data-intensive applications a so-called prototype database is needed. This paper investigates how a prototype database can be built. Two different approaches are analysed, namely test databases and sample databases; the former populates the resulting database with synthetic values, while the latter uses data values from an existing database. The application areas that require prototype databases, in addition to requirements analysis, are also identified. The paper reports on existing research into the construction of both types of prototype databases, and indicates to which type of application area each is best suited. This paper advocates for the use of sample databases when an operational database is available, as is commonly the case in software maintenance and evolution. Domain-relevant data values and integrity constraints will produce a prototype database which will support the information system development process better than synthetic data. The process of extracting a sample database is also investigated. Copyright © 2002 John Wiley & Sons, Ltd. [source] Progress in corrosion protection as a requirement for technical progress,MATERIALS AND CORROSION/WERKSTOFFE UND KORROSION, Issue 7 2009W. Fürbeth Abstract In many of the more recent technologies, corrosion plays a crucial role in determining their successful application. The present paper identifies such important corrosion issues in a number of technologies, which are currently under development or have been recently discussed. In this sense, CO2 sequestration, fuel cells, offshore wind energy and other offshore technologies, geothermal energy, advanced coal conversion technologies, nuclear energy, light weight construction in transport, ionic liquids as well as medical technologies are discussed with respect to corrosion problems and existing research needs. In this way, this paper intends to show the complexity and the variety of corrosion topics of today and at the same time, point at the economic aspects and the impact on daily life. In the end, this leads to an introduction of the World Corrosion Organization and its study on future needs for research and development in materials degradation and corrosion control. [source] Factors Affecting How Second Language Spanish Students Derive Meaning from ContextMODERN LANGUAGE JOURNAL, Issue 2 2003Diana Frantzen Although first language (L1) and second language (L2) research has indicated that the meanings of unknown words can be derived from the contexts in which they occur, research has also found limitations to the value of context. Using data gathered in a classroom experiment on L2 vocabulary acquisition (Frantzen, 1998), the present study sought to determine some of the reasons why the context in which a word appears does not always lead a language learner to an accurate interpretation of its meaning. It expands the existing research by using a natural, intact, unmanipulated text as the context (an aspect underrepresented in current L2 word inferencing literature). Analysis of the students' answers, their self,reported guessing strategies, the contexts in which the words appeared, and the text's glossing revealed that the "blame" for the incorrect answers may be placed on: (a) the context itself, (b) the students' behavior, and in a minor way (c) the story's glossing. Numerous patterns are presented and discussed in light of other L1 and L2 research and new patterns are reported.
