The Impact of Multiple Dimensions of Ethnic Identity on Discrimination and Adolescents' Self-Estees

JOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 11 2003
Andrea J. Romero
The rejection-identification model is investigated with multiple dimensions of ethnic identity in a sample of Mexican American youth. It is hypothesized that more perceived discrimination will be associated with higher ethnic identity in general, but that the multiple dimensions of ethnic identity will be associated differentially with discrimination. Higher perceived discrimination will be associated with more ethnic exploration and less ethnic affirmation. Self-report questionnaires were completed by middle school students of Mexican descent (N= 881). Based on structural equation modeling, the data were found to fit the rejection-identification model (p < .05). Higher discrimination was associated with lower ethnic affirmation (p < .05) and lower ethnic exploration (p < .05). Post hoc analyses indicated a significant interaction between discrimination and ethnic affirmation (p < .01) such that youth with high ethnic affirmation who experienced high discrimination still reported high self-esteem. The findings are discussed in the context of understanding methods of coping with prejudice and discrimination that will enhance the mental well-being of minority youth. [source]

The Measurement of Daily Surge and Its Relevance to Disaster Preparedness

ACADEMIC EMERGENCY MEDICINE, Issue 11 2006
Melissa L. McCarthy MS
This article reviews what is known about daily emergency department (ED) surge and ED surge capacity and illustrates its potential relevance during a catastrophic event. Daily ED surge is a sudden increase in the demand for ED services. There is no well-accepted, objective measure of daily ED surge. The authors propose that daily and catastrophic ED surge can be measured by the magnitude of the surge, as well as by the nature and severity of the illnesses and injuries that patients present with during the surge. The magnitude of an ED surge can be measured by the patient arrival rate per hour. The nature and severity of the surge can be measured by the type (e.g., trauma vs. infection vs. biohazard) and acuity (e.g., triage level) of the surge. Surge capacity is defined as the extent to which a system can respond to a rapid and sizeable increase in the demand for resources. ED surge capacity includes multiple dimensions, such as systems, space, staffing, and supplies. A multidimensional measure is needed that reflects both the core components and their relative contribution to ED surge capacity. Although many types of factors may influence ED surge capacity, relatively little formal research has been conducted in this area. A better understanding of daily ED surge capacity and influencing factors will improve our ability to simulate the potential impact that different types of catastrophic events may have on the surge capacity of hospital EDs nationwide.

Consequences of Satisfaction with Pay Systems: Two Field Studies

INDUSTRIAL RELATIONS, Issue 1 2000
Marcia P. Miceli
Research on pay satisfaction has been criticized for inattention to determining whether its multiple dimensions have different consequences and for overreliance on cross-sectional designs. Structural equation analyses of data from two field studies showed that satisfaction with pay systems, but not pay levels, led to greater perceived organizational support, which in turn affected employer commitment and organizational citizenship. Union commitment was a positive function of pay system satisfaction and a negative function of pay level satisfaction. [source]

What Is Ecological Validity?

INFANCY, Issue 4 2001
A Dimensional Analysis
Ecological validity has typically been taken to refer to whether or not one can generalize from observed behavior in the laboratory to natural behavior in the world. Although common in current discussions of research, the idea of ecological validity has a long history in psychological thought. A brief historical examination of this idea reveals that concerns with ecological validity are evident in multiple dimensions of experimental work, including the nature of the experimental setting, the stimuli under investigation, and the observer's response employed as the measure. One problem with this multidimensionality, however, is that no explicit criteria have been offered for applying this concept to an evaluation of research. One consequence of this problem is that concerns with ecological validity can be raised in most experimental situations. This article includes a discussion of some demands of ecological validity and the nature of these different dimensions, as well as a critical evaluation of research on the development of mobility with respect to these constraints.

The Concept of Social Exclusion in the European Union: Context, Development and Possibilities

JCMS: JOURNAL OF COMMON MARKET STUDIES, Issue 3 2000
Rob Atkinson
In recent years the term ,social exclusion' has come to occupy a central place in the discussion of social policy and inequality in Europe. While the notion has acquired important strategic connotations, by stressing structural and cultural/social processes, the precise meaning of the term remains somewhat elusive. This article focuses on the reason for and the manner in which the notion of social exclusion has developed within the EU social policy discourse, aiming to provide a clearer understanding of its origins, functions and multiple dimensions. Whilst adopting a critical approach to the notion of social exclusion, the article suggests that the concept has played a positive role in keeping issues such as inequality and poverty on the policy agenda. The article also suggests possible ways in which social exclusion might be developed in a climate which has become less conducive, if not hostile, to an autonomous, activist EU social policy.

Concept clarification of neonatal neurobehavioural organization

JOURNAL OF ADVANCED NURSING, Issue 5 2008
Aleeca F. Bell
Abstract Title.,Concept clarification of neonatal neurobehavioural organization Aim., This paper is a report of a concept analysis of neonatal neurobehavioural organization for healthy full-term infants. Background., The neonatal period is an opportune time for researchers and clinicians to assess and intervene for optimal neurobehavioural organization. Yet there is inconsistency and lack of clarity in a scientifically grounded definition of neonatal neurobehavioural organization. Clarification of the concept will strengthen research findings that influence practice for optimal infant development. Method., A concept analysis of the literature between 1939 and 2007 (n = 57) was conducted using Penrod and Hupcey's principle-based concept analysis and Morse's concept clarification. Findings., The concept analysis within and across multiple disciplines revealed: (1) a view of the concept as a holistic phenomenon with multiple dimensions; (2) no agreement on the ideal instrument to operationally define the concept; and (3) consistency in implied meaning, but great variability in terminology. Neonatal neurobehavioural organization was defined as the ability of the neonate to use goal-directed states of consciousness, in reciprocal interaction with the caregiving environment, to facilitate the emergence of differentiating, hierarchical, and coordinated neurobehavioural systems, with ever-increasing resiliency and capacity to learn from complex stimuli. Conclusion., A clear conceptual definition will help the international community to communicate effectively within and between disciplines and to apply evidence-based research findings. It will encourage the development of valid and reliable instruments to capture the concept's multiple dimensions and direct attention to the infant's experience, which sculpts early neurobehavioural organization.

Analysis of scattering from polydisperse structure using Mellin convolution

JOURNAL OF APPLIED CRYSTALLOGRAPHY, Issue 2 2006
Norbert Stribeck
This study extends a mathematical concept for the description of heterogeneity and polydispersity in the structure of materials to multiple dimensions. In one dimension, the description of heterogeneity by means of Mellin convolution is well known. In several papers by the author, the method has been applied to the analysis of data from materials with one-dimensional structure (layer stacks or fibrils along their principal axis). According to this concept, heterogeneous structures built from polydisperse ensembles of structural units are advantageously described by the Mellin convolution of a representative template structure with the size distribution of the templates. Hence, the polydisperse ensemble of similar structural units is generated by superposition of dilated templates. This approach is particularly attractive considering the advantageous mathematical properties enjoyed by the Mellin convolution. Thus, average particle size, and width and skewness of the particle size distribution can be determined from scattering data without the need to model the size distributions themselves. The present theoretical treatment demonstrates that the concept is generally extensible to dilation in multiple dimensions. Moreover, in an analogous manner, a representative cluster of correlated particles (e.g. layer stacks or microfibrils) can be considered as a template on a higher level. Polydispersity of such clusters is, again, described by subjecting the template structure to the generalized Mellin convolution. The proposed theory leads to a simple pathway for the quantitative determination of polydispersity and heterogeneity parameters. Consistency with the established theoretical approach of polydispersity in scattering theory is demonstrated. The method is applied to the best advantage in the field of soft condensed matter when anisotropic nanostructured materials are to be characterized by means of small-angle scattering (SAXS, USAXS, SANS).

The Impact of Multiple Dimensions of Ethnic Identity on Discrimination and Adolescents' Self-Estees

Partial least squares path modelling for relations between baseline factors and treatment outcomes in periodontal regeneration

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 11 2009
Yu-Kang Tu
Abstract Background: Some clinical outcome variables in periodontal research are mathematically coupled, and it is not feasible to include all the mathematically coupled variables in an ordinary least squares (OLS) regression analysis. The simplest solution to this problem is to drop at least one of the mathematically coupled variables. However, this solution is not satisfactory when the mathematically coupled variables have distinctive clinical implications. Material and Methods: Partial least squares (PLS) methods were used to analyse data from a study on guided tissue regeneration. Relationships between characteristics of baseline lesions and treatment outcomes after 1 year were analysed using PLS, and the results were compared with those from OLS regression. Results: PLS analysis suggested that there were multiple dimensions in the characteristics of baseline lesion: vertical dimension was positively associated with probing pocket depth (PPD) reduction and clinical attachment level (CAL) gain, whilst horizontal dimension was negatively associated with the outcome. Baseline gingival recession had a negative association with PPD reduction but a small positive one with CAL gain. Conclusion: PLS analysis provides new insights into the relationships between baseline characteristics of infrabony defects and periodontal treatment outcomes. The hypothesis of multiple dimensions in baseline lesions needs to be validated by further analysis of different datasets. [source]

Network financial support and conflict as predictors of depressive symptoms among a highly disadvantaged population

JOURNAL OF COMMUNITY PSYCHOLOGY, Issue 1 2007
Amy R. Knowlton
The study examined multiple dimensions of social support as predictors of depressive symptoms among a highly vulnerable population. Social network analysis was used to assess perceived and enacted dimensions of support (emotional, financial, instrumental), network conflict, closeness, and composition. Participants were 393 current and former injection drug users who were 72% , poverty level, 96% African American, 39% HIV seropositive. At baseline, 37% had high depression scores (CES-D , 16). Adjusted logistic regression indicated that for every additional network member providing financial support, the odds of probable depression 1 year later decreased by 23%, and for every additional conflictive network tie the odds of depression increased by 57%. Findings suggest the greater importance to this population's psychological well-being of received support specific to environmental demands, rather than support perceived potentially available. The findings suggest potential directions for intervention. © 2007 Wiley Periodicals, Inc. [source]

Connective Ethnography for the Exploration of e-Science

JOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 2 2007
Christine Hine
E-science comprises diverse sites, connected in complex and heterogeneous ways. While ethnography is well established as a way of exploring the detail of the knowledge production process, some strategic adaptations are prompted by this spatial complexity of e-science. This article describes a study that focused on the biological discipline of systematics, exploring the ways in which use of a variety of information and communication technologies has become a routine part of disciplinary practice. The ethnography combined observation and interviews within systematics institutions with mailing list participation, exploration of web landscapes, and analysis of expectations around information and communications technologies as portrayed in policy documents. Exploring connections among these different activities offers a means of understanding multiple dimensions of e-science as a focus of practice and policy. It is important when studying e-science to engage critically with claims about the transformative capacity of new technologies and to adopt methodologies that remain agnostic in the face of such claims: A connective approach to ethnography offers considerable promise in this regard.

Evidence-based medicine: the need for a new definition

JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 2 2000
S. Buetow MA PhD
Abstract Evidence is defined by its ability to establish or support conclusions. Evidence-based medicine (EBM) equates evidence with scientific evidence and views factors such as clinical expertise as important in moving from evidence to action. In contrast, we suggest that EBM should acknowledge multiple dimensions of evidence including scientific evidence, theoretic evidence, practical evidence, expert evidence, judicial evidence and ethics-based evidence. What EBM loses by not acknowledging these dimensions as evidence is the ability, among other things, to make and defend judgements based on understandings that complement science and are no less important than those science can offer. We argue for a new definition of EBM that, without forced accommodation or unacceptable compromise, acknowledges dimensions of evidence produced within and outside science. [source]

Solidarity and Conflict Between Adult Children and Parents: A Latent Class Analysis

JOURNAL OF MARRIAGE AND FAMILY, Issue 4 2006
Ruben I. Van Gaalen
Using multiple dimensions of solidarity and conflict in a latent class analysis, we develop a typology of adult child,parent relationships. The data (N= 4,990) are from the first wave of the Netherlands Kinship Panel Study. In descending order of relationship quality, the 5 types are harmonious (akin to relationships with friends), ambivalent (intensive exchange of material support accompanied by strain), obligatory (just keeping in touch), affective (emotionally supportive with few other meaningful exchanges), and discordant (predominantly negative engagement). The types are differentiated by gender, age, family size, geographic distance, and parental marital history, indicating that they are not fixed but are shaped by social-structural conditions.

Continuity and Change in Marital Quality Between 1980 and 2000

JOURNAL OF MARRIAGE AND FAMILY, Issue 1 2003
Paul R. Amato
We use data from two national surveys of married individuals,one from 1980 and the other from 2000,to understand how three dimensions of marital quality changed during this period. Marital happiness and divorce proneness changed little between 1980 and 2000, but marital interaction declined significantly. A decomposition analysis suggested that offsetting trends affected marital quality. Increases in marital heterogamy, premarital cohabitation, wives' extended hours of employment, and wives' job demands were associated with declines in multiple dimensions of marital quality. In contrast, increases in economic resources, decision-making equality, nontraditional attitudes toward gender, and support for the norm of lifelong marriage were associated with improvements in multiple dimensions of marital quality. Increases in husbands' share of housework appeared to depress marital quality among husbands but to improve marital quality among wives. [source]

A study of the criteria used by healthcare professionals, managers and patients to represent and evaluate quality care

JOURNAL OF NURSING MANAGEMENT, Issue 2 2001
M. Attree msc, bnurs
Aim,To explore the perceptions of and criteria used by healthcare professionals, managers, patients and relatives to represent and evaluate their concept of quality care. Methods A qualitative approach using grounded theory was adopted in thisexploratory descriptive study. Data collected by semi-structured interviews from a purposive sample of nurses, doctors, managers (n = 36), patients (n = 34) and relatives (n = 7) from one acute medical ward, were subjected to content, question and thematic analysis, using an inductive categorizing scheme. Findings Three categories of criteria relating to Care Resources, Processes and Outcomes were identified by healthcare professionals, managers, patients and relatives. Resource criteria included Human Resources: staff numbers, ratio to patients, skill mix; as well as Environmental/Physical and Financial Resources. Process criteria included Care Functions, Practices and Standards as well as Interpersonal Processes. Outcome criteria were either patient-focused: feeling comfort, happy, informed and satisfied; or health-related: maintenance or progress with health problems and goals. Conclusions The criteria used by healthcare stakeholders in this study were notunusual; virtually all were supported by the literature, a proportion of which was evidence-based. The criteria identified in this study are however consensual, agreed upon by healthcare professionals, managers, patients and relatives as representing their view of quality care. These consensual criteria could be used as unifying constructs for the development and testing of more comprehensive, reliable and valid methods of evaluating quality care which represent its multiple dimensions and perspectives.

symptom Experience in Women After Hysterectomy

JOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 5 2001
Kimberly H. Kim RN
Objective: To review the literature addressing the symptom experience of women after hysterectomy. Data Sources: Computerized searches in MEDLINE and CINAHL, as well as texts and references cited in articles. Key concepts in the searches included hysterectomy, sleep disturbance and pain, hysterectomy and fatigue, hysterectomy, depression, and depressed mood. Study Selection: Articles and comprehensive works relevant to key concepts and published after 1970, with an emphasis on new findings from 1990 to 2000. Sixty-four citations were identified as useful to this review. Data Extraction: Data were organized under the following headings: women and hysterectomy, biopsychosocial perspectives, common symptoms after hysterectomy (pain, disturbed sleep, fatigue, depressed mood, anxiety), and significance of review (implications). Data Synthesis: Literature suggests that after a hysterectomy, women experience complications during the postoperative recovery period that may vary with the type of surgical procedure. During this period, the quantity and quality of sleep as well as other symptoms (pain, fatigue, anxiety, and depression) are influenced by various physiologic, psychologic, and social factors. Despite limited evidence that sleep problems may occur frequently during the recovery period, only a few researchers have systematically examined sleep patterns in women after hysterectomy. None of these studies, however, used objective sleep measures or examined multiple dimensions of these women's lives. Conclusions: This review conceptualized the women's symptom experience as the experience of specific symptoms (pain, sleep disturbance, fatigue, depressed mood, and anxiety) that were influenced by biopsychosocial factors.

Procedural justice's relationship with turnover: explaining past inconsistent findings

JOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 4 2007
Richard A. Posthuma
Despite arguments for a significant negative relationship, there have been ambiguous findings on the empirical relationship between procedural justice and turnover behavior. This study attempts to clarify these past findings by examining the effects of multiple dimensions of procedural justice on the voluntary turnover behavior of nurses in a work-scheduling context (N,=,190). The advance notice and consistency dimensions were significantly and negatively correlated with turnover behavior. Two dimensions of procedural justice had divergent effects on actual turnover behaviors in a logistic regression model. Advance notice was negatively related to turnover, while representativeness of views was positively related to turnover. Copyright © 2006 John Wiley & Sons, Ltd. [source]

Packaging Support for Low-Income Families: Policy Variation across the United States

JOURNAL OF POLICY ANALYSIS AND MANAGEMENT, Issue 3 2001
Marcia K. Meyers
This paper addresses a gap in state-level comparative social policy research by analyzing policies that support low-income families with children. Variation in state policy "packages" is measured by considering three characteristics of 11 social programs. Individual measures of policy are found to be weakly and inconsistently inter-correlated at the state level, but when cluster analysis is used to analyze multiple dimensions simultaneously, five clusters or regime types are identified that have distinctive policy approaches. These range from the most minimal provisions, to conservative approaches emphasizing private responsibility, to integrated approaches that combine generous direct assistance with employment support and policies that enforce family responsibility. A comparison of a subset of programs at two points in time (1994 and 1998) suggests that states made substantial changes in cash assistance and taxation policies after the 1996 federal welfare reforms. The magnitude and direction of these changes remained consistent with the state clusters identified in 1994. © 2001 by the Association for Public Policy Analysis and Management. [source]

Live imaging of fluorescent proteins in chordate embryos: From ascidians to mice

MICROSCOPY RESEARCH AND TECHNIQUE, Issue 3 2006
Yale J. Passamaneck
Abstract Although we have advanced in our understanding of the molecular mechanisms intrinsic to the morphogenesis of chordate embryos, the question of how individual developmental events are integrated to generate the final morphological form is still unresolved. Microscopic observation is a pivotal tool in developmental biology, both for determining the normal course of events and for contrasting this with the results of experimental and pathological perturbations. Since embryonic development takes place in three dimensions over time, to fully understand the events required to build an embryo we must investigate embryo morphogenesis in multiple dimensions in situ. Recent advances in the isolation of naturally fluorescent proteins, and the refinement of techniques for in vivo microscopy offer unprecedented opportunities to study the cellular and molecular events within living, intact embryos using optical imaging. These technologies allow direct visual access to complex events as they happen in their native environment, and thus provide greater insights into cell behaviors operating during embryonic development. Since most fluorescent protein probes and modes of data acquisition are common across species, we have chosen the mouse and the ascidian, two model organisms at opposite ends of the chordate clade, to review the use of some of the current genetically-encoded fluorescent proteins and their visualization in vivo in living embryos for the generation of high-resolution imaging data.

Research demonstrates that most college faculty lack a substantive concept of critical thinking, though they mistakenly think otherwise. This chapter spells out the implications of such a robust concept and emphasizes that success in bringing a substantive concept of critical thinking to college faculty requires well-planned, long-term professional development based explicitly on the multiple dimensions of a substantive concept of critical thinking.

A Qualitative Case Study Review of Role Transition in Community Nursing

NURSING FORUM, Issue 4 2007
Joyce Zurmehly PhD
PURPOSE.,This paper aims to describe existing community nursing practices and to explore factors that are associated with the transition of clinical practice from acute care settings to community care settings. METHOD.,This qualitative case study assessment described existing community nurse practices and explored factors that were associated with the transition to community practice from acute care settings. The 48 participants in this case study were registered nurses who were working in community care nursing during the interview process. CONCLUSIONS.,The results of this investigation revealed themes derived from data collection, including autonomy, client and family, education, and community as nursing work. This study indicated that making the transition to community-based nursing includes conceptual as well as emotional adjustments. Community nursing practice was seen by the participants as nursing that captures a holistic approach incorporating multiple dimensions from psychological, sociological, economic, and physical to spiritual aspects that provides services in interaction between the community nurse, the client, and the family. The findings indicate a need for additional supportive preparation strategies incorporated into nursing orientation and continuing education programs. Future research investigating agency culture and socialization would provide a more definitive survey of perceptions and competencies needed for role. [source]

Clinical and psychological characteristics of TMD patients with trauma history

ORAL DISEASES, Issue 2 2010
H-II Kim
Oral Diseases (2010) 16, 188,192 Objective:, The purpose of this study was to investigate clinical and psychological characteristics of temporomandibular disorders (TMD) patients with trauma history. Materials and methods:, The clinical and psychological characteristics of 34 TMD patients with trauma history were compared with those of 340 TMD patients without trauma history. Craniomandibular index (CMI) was used for clinical characteristics of TMD patients. Symptom severity index (SSI) was used to assess the multiple dimensions of pain. Symptom checklist-90-revision (SCL-90-R) was used for psychological evaluation. Results:, Temporomandibular disorders patients with trauma history displayed significantly higher CMI and palpation index. TMD patients with trauma history also exhibited higher values in duration, sensory intensity, affective intensity, tolerability, scope of symptom, and total SSI score. In addition, these patients showed significantly higher values in symptom dimensions of somatization, depression, anxiety, phobic anxiety, and paranoid ideation. Among the symptom dimensions of SCL-90-R, somatization showed the most significant correlations with CMI and SSI. Conclusions:, Temporomandibular disorders patients with trauma history displayed more severe subjective, objective, and psychological dysfunction than those without trauma history. Pain of myogenous origin, history of physical trauma, and psychosocial dysfunction were all closely related. [source]

Why forgiveness may protect against depression: Hopelessness as an explanatory mechanism

PERSONALITY AND MENTAL HEALTH, Issue 2 2008
Loren L. Toussaint
This study examined associations between multiple dimensions of forgiveness with hopelessness and depression. Further, this study investigated the extent to which hopelessness mediated associations between forgiveness and depression. We used an adapted model and drew on beginning work showing associations between forgiveness, hope/hopelessness and depression. We predicted that forgiveness would be significantly inversely correlated with hopelessness and depression, and that hopelessness would mediate the associations between forgiveness and depression. We controlled for religiousness/spirituality and demographic factors in our analyses, and used data from a nationally representative probability sample of 1,423 adults, ages 18 years and older. Results showed that forgiveness of oneself and others was negatively correlated, and seeking forgiveness was positively correlated with depression. Forgiveness of oneself and others was associated with hopelessness. Mediation analyses revealed that hopelessness partially mediated the associations between forgiveness of oneself and others with depression. The present findings provide support for theoretical and conceptual work connecting forgiveness, hope and mental health, and add to a scant empirical literature on these topics.

Compassion Fatigue and Psychological Distress Among Social Workers: A Validation Study

AMERICAN JOURNAL OF ORTHOPSYCHIATRY, Issue 1 2006
Richard E. Adams PhD
Few studies have focused on caring professionals and their emotional exhaustion from working with traumatized clients, referred to as compassion fatigue (CF). The present study had 2 goals: (a) to assess the psychometric properties of a CF scale, and (b) to examine the scale's predictive validity in a multivariate model. The data came from a survey of social workers living in New York City following the September 11, 2001, terrorist attacks on the World Trade Center. Factor analyses indicated that the CF scale measured multiple dimensions. After overlapping items were eliminated, the scale measured 2 key underlying dimensions,secondary trauma and job burnout. In a multivariate model, these dimensions were related to psychological distress, even after other risk factors were controlled. The authors discuss the results in light of increasing the ability of professional caregivers to meet the emotional needs of their clients within a stressful environment without experiencing CF.

Managing uncertain, complex product development in high-tech firms: in search of controlled flexibility

R & D MANAGEMENT, Issue 4 2010
Daniel Olausson
This paper investigates ways of managing complexity and uncertainty in R&D simultaneously. Previous research on the subject indicates that these dimensions require different approaches, but these studies tend to provide suggestions either on managing complexity in stable industries or on handling uncertainty in less complex projects. In this paper, the two dimensions are studied simultaneously in three commercial product development projects at a firm that may be viewed as an extreme case of complexity and with multiple dimensions of uncertainty. The paper illustrates that a critical issue in this kind of high-tech development is the search for and development of approaches that integrate and balance needs for formal organizational control with high levels of project flexibility. Four key elements of such integrated approaches are identified: hybrid formal systems, structured interaction in public arenas, transparent visual communication tools, and a system of participative reflection.

The Effects of Strategic and Economic Interdependence on International Conflict Across Levels of Analysis

AMERICAN JOURNAL OF POLITICAL SCIENCE, Issue 1 2009
Zeev Maoz
This study develops a Social Network Analytic approach to conceptualize and measure interdependence across levels of analysis. This framework contains several innovations. First, it integrates "sensitivity interdependence",the effects of changes in one state on other states,with "vulnerability interdependence",the opportunity costs of breaking a relationship. Second, it measures interdependence at different levels of analysis and across multiple relationships. Third, it integrates multiple dimensions of interdependence into a single measure. I derive hypotheses from the realist and liberal paradigms regarding the effects of strategic and economic interdependence on monadic, dyadic, and systemic conflict. These hypotheses are tested via data on alliances, military capability, and trade. The findings provide robust support to the expectations of the liberal paradigm regarding the effects of strategic and economic interdependence on conflict. On the other hand, the expectations of the realist paradigm are not supported. I discuss the theoretical and empirical implications of this approach. [source]

STRATEGY AND STRUCTURE OF MARKET COMPETITION: THE TAIWANESE CABLE TV INDUSTRY IN THE 1990s

THE DEVELOPING ECONOMIES, Issue 3 2002
Lu-Lin CHENG
Cable TV plays a dominant role in the media environment of Taiwanese society. Before the passage of the Cable TV Law in 1993, the industry was a vibrant informal sector; it was highly differentiated, and acted as a democratic alternative to the formal media. The 1993 Cable TV Law, which designed a competitive market with five licenses issued in each area, was touted as a victory for democracy by the opposition parties. In less than a decade, however, drastic merger movements led to a monopolistic structure. The abuse of monopolistic power has become pervasive. This article studies this unexpected historical twist by examining the industry's market dynamics during the country's democratization in the 1990s. To show the path-dependent mechanisms in the nonlinear development trajectory of the market, a sociological approach is applied that emphasizes firms' competitive strategies in controlling the multiple dimensions of uncertainties and rules that induce this competition.

Assessing and Documenting General Competencies in Otolaryngology Resident Training Programs,

THE LARYNGOSCOPE, Issue 5 2006
Rick M. Roark PhD
Abstract Objectives: The objectives of this study were to: 1) implement web-based instruments for assessing and documenting the general competencies of otolaryngology resident education, as outlined by the Accreditation Council of Graduate Medical Education (ACGME); and 2) examine the benefit and validity of this online system for measuring educational outcomes and for identifying insufficiencies in the training program as they occur. Methods: We developed an online assessment system for a surgical postgraduate education program and examined its feasibility, usability, and validity. Evaluations of behaviors, skills, and attitudes of 26 residents were completed online by faculty, peers, and nonphysician professionals during a 3-year period. Analyses included calculation and evaluation of total average performance scores of each resident by different evaluators. Evaluations were also compared with American Board of Otolaryngology-administered in-service examination (ISE) scores for each resident. Convergent validity was examined statistically by comparing ratings among the different evaluator types. Results: Questionnaires and software were found to be simple to use and efficient in collecting essential information. From July 2002 to June 2005, 1,336 evaluation forms were available for analysis. The average score assigned by faculty was 4.31, significantly lower than that by nonphysician professionals (4.66) and residents evaluating peers (4.63) (P < .001), whereas scores were similar between nonphysician professionals and resident peers. Average scores between faculty and nonphysician groups showed correlation in constructs of communication and relationship with patients, but not in those of professionalism and documentation. Correlation was observed in respect for patients but not in medical knowledge between faculty and resident peer groups. Resident ISE scores improved in the third year of the study and demonstrated high correlation with faculty perceptions of medical knowledge (r = 0.65, P = .007). Conclusions: Compliance for completion of forms was 97%. The system facilitated the educational management of our training program along multiple dimensions. The small perceptual differences among a highly selected group of residents have made the unambiguous validation of the system challenging. The instruments and approach warrant further study. Improvements are likely best achieved in broad consultation among other otolaryngology programs. [source]

Religious and Non-Religious Pathways to Stress-Related Growth in Cancer Survivors

APPLIED PSYCHOLOGY: HEALTH AND WELL-BEING, Issue 3 2009
Crystal L. Park
While religiousness and spirituality are important to many cancer survivors, relations of religiousness and spirituality with the stress-related growth commonly reported by survivors have not been well documented. In the present study, we examined the linkages between personal religiousness, religious control appraisals for the cancer, and religious coping with subsequent stress-related growth, and compared them with a parallel secular pathway, hope, self-control appraisals, and active coping. In all, 172 young to middle-aged adult survivors (113 women, 59 men, mean age = 45 years) of a variety of types of cancer who had been diagnosed approximately 2.5 years prior were assessed twice across a 1-year period. A structural equation model indicated that while both pathways predicted stress-related growth, the religious pathway was a much stronger predictor of subsequent stress-related growth than was the secular pathway. We suggest that more attention should be given to the influence of multiple dimensions of religiousness and spirituality on growth to better understand the transformative processes reported by many survivors.
