Kinds of Support Terms modified by Support Selected AbstractsADAPTATION KNOWLEDGE ACQUISITION: A CASE STUDY FOR CASE-BASED DECISION SUPPORT IN ONCOLOGYCOMPUTATIONAL INTELLIGENCE, Issue 3-4 2006Mathieu D'Aquin Kasimir is a case-based decision support system in the domain of breast cancer treatment. For this system, a problem is given by the description of a patient and a solution is a set of therapeutic decisions. Given a target problem, Kasimir provides several suggestions of solutions, based on several justified adaptations of source cases. Such adaptation processes are based on adaptation knowledge. The acquisition of this kind of knowledge from experts is presented in this paper. It is shown how the decomposition of adaptation processes by introduction of intermediate problems can highlight simple and generalizable adaptation steps. Moreover, some adaptation knowledge units that are generalized from those acquired for Kasimir are presented. This knowledge can be instantiated in other case-based decision support systems, in particular in medicine. [source] IMAGES OF GOD AND PUBLIC SUPPORT FOR CAPITAL PUNISHMENT: DOES A CLOSE RELATIONSHIP WITH A LOVING GOD MATTER?,CRIMINOLOGY, Issue 4 2006JAMES D. UNNEVER This study argues that the nature and intensity of a person's relationship with God creates a transposable cognitive schema that shapes people's views toward public policies such as executing convicted murderers. In this context, we investigate whether Americans who report having a close personal relationship with a loving God are less likely to support the death penalty. We hypothesize that such a relationship tempers the tendency to see punitiveness as an appropriate response to human failings. Individuals who hold a loving God image are more likely to believe that God responds to those who have "failed" or "sinned" by demonstrating unconditional love, forgiveness, and mercy. Accordingly, support for capital punishment is problematic because it contradicts the image of a merciful, forgiving deity; God's purpose,and admonition to believers,is to demonstrate compassion toward those who have trespassed against others. We test these possibilities using the 2004 General Social Survey (GSS). Controlling for a range of religious factors and other known predictors of death penalty attitudes, the results show that Americans with a personal relationship with a loving God are less likely to support capital punishment for convicted murderers. [source] SOCIAL SUPPORT, INEQUALITY, AND HOMICIDE: A CROSS-NATIONAL TEST OF AN INTEGRATED THEORETICAL MODEL,CRIMINOLOGY, Issue 3 2003TRAVIS C. PRATT Social support, institutional anomie, and macrolevel general strain perspectives have emerged as potentially important explanations of aggregate levels of crime. Drawing on insights from each of these perspectives in a cross-national context, the analyses show that 1) our measure of social support is inversely related to homicide rates, 2) economic inequality also maintains a direct relationship with homicide rates, and 3) social support significantly interacts with economic inequality to influence homicide rates. The implications of the analysis for ongoing discourse concerning the integration of these criminological theories and the implications for the development of effective crime control policies are discussed. [source] FEDERAL SUPPORT OF LOCAL CRIMINAL JUSTICE OPERATIONS*CRIMINOLOGY AND PUBLIC POLICY, Issue 3 2008ALFRED BLUMSTEIN First page of article [source] EXECUTING THE INNOCENT AND SUPPORT FOR CAPITAL PUNISHMENT: IMPLICATIONS FOR PUBLIC POLICYCRIMINOLOGY AND PUBLIC POLICY, Issue 1 2005JAMES D. UNNEVER Research Summary: The issue of whether innocent people have been executed is now at the center of the debate concerning the legitimacy of capital punishment. The purpose of this research was to use data collected by the Gallup Organization in 2003 to investigate whether Americans who believed that an innocent person had been executed were less likely to support capital punishment. We also explored whether the association varied by race, given that African Americans are disproportionately affected by the death penalty. Our results indicated that three-quarters of Americans believed that an innocent person had been executed for a crime they did not commit within the last five years and that this belief was associated with lower levels of support for capital punishment, especially among those who thought this sanction was applied unfairly. In addition, our analyses revealed that believing an innocent person had been executed had a stronger association with altering African American than white support for the death penalty. Policy Implications: A key claim of death penalty advocates is that a high proportion of the public supports capital punishment. In this context, scholars opposing this sanction have understood the importance of showing that the public's support for executing offenders is contingent and shallower than portrayed by typical opinion polls. The current research joins this effort by arguing that the prospect of executing innocents potentially impacts public support for the death penalty and, in the least, creates ideological space for a reconsideration of the legitimacy of capital punishment. [source] ON REDUCING WHITE SUPPORT FOR THE DEATH PENALTY: A PESSIMISTIC APPRAISALCRIMINOLOGY AND PUBLIC POLICY, Issue 1 2005STEVEN E. BARKAN [source] Four-Year Follow-up on Endovascular Radiofrequency Obliteration of Great Saphenous RefluxDERMATOLOGIC SURGERY, Issue 2 2005Robert F. Merchant MD Background Endovascular radiofrequency obliteration has been used since 1998 as an alternative to conventional vein stripping surgery for elimination of saphenous vein insufficiency. Objective To demonstrate the long-term efficacy of this treatment modality. Methods Data were prospectively collected in a multicenter ongoing registry. Only great saphenous vein above-knee treatments were included in this study. Eight hundred ninety patients (1,078 limbs) were treated prior to November 2003 at 32 centers. Clinical and duplex ultrasound follow-up was performed at 1 week, 6 months, and 1, 2, 3, and 4 years. Results Among 1,078 limbs treated, 858 were available for follow-up within 1 week, 446 at 6 months, 384 at 1 year, 210 at 2 years, 114 at 3 years, and 98 at 4 years. The vein occlusion rates were 91.0%, 88.8%, 86.2%, 84.2%, and 88.8%, respectively; the reflux-free rates were 91.0%, 89.3%, 86.2%, 86.0%, and 85.7%, respectively; and the varicose vein recurrence rates were 7.2%, 13.5%, 17.1%, 14.0%, and 21.4%, respectively, at each follow-up time point at 6 months, and 1, 2, 3, and 4 years. Patient symptom improvement persisted over 4 years. Conclusions Endovascular temperature-controlled radiofrequency obliteration of saphenous vein reflux exhibits an enduring treatment efficacy clinically, anatomically, and hemodynamically up to 4 years following treatment.

[source] Are Aggressive Treatment Strategies Less Cost-Effective for Older Patients?JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2001Aggressive Care for Patients with Acute Respiratory Failure, The Case of Ventilator Support OBJECTIVES: A common assumption is that life-sustaining treatments are much less cost-effective for older patients than for younger patients. We estimated the incremental cost-effectiveness of providing mechanical ventilation and intensive care for patients of various ages who had acute respiratory failure. DESIGN: Retrospective analysis of data on acute respiratory failure from Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT). SETTING: Acute hospital. PARTICIPANTS: 1,005 with acute respiratory failure; 963 received ventilator support and 42 had ventilator support withheld. MEASUREMENTS: We studied 1,005 patients enrolled in a five-center study of seriously ill patients (SUPPORT) with acute respiratory failure (pneumonia or acute respiratory distress syndrome and an Acute Physiology Score ,10) requiring ventilator support. For cost-effectiveness analyses, we estimated life expectancy based on long-term follow-up of SUPPORT patients and estimated utilities (quality-of-life weights) using time-tradeoff questions. We used hospital fiscal data and Medicare data to estimate healthcare costs. We divided patients into three age groups (<65, 65,74, and ,75 years); for each age group, we performed separate analyses for patients with a ,50% probability of surviving at least 2 months (high-risk group) and those with a> 50% probability of surviving at least 2 months (low-risk group). RESULTS: Of the 963 patients who received ventilator support, 44% were female; 48% survived 6 months; and the median (25th, 75th percentile) age was 63 (46, 75) years. For the 42 patients for whom ventilator support was withheld, the median survival was 3 days. For low-risk patients (>50% estimated 2-month survival), the incremental cost (1998 dollars) per quality-adjusted life-year (QALY) saved by providing ventilator support and aggressive care increased across the three age groups ($32,000 for patients age <65, $44,000 for those age 65,74, and $46,000 for those age ,75). For high-risk patients, the incremental cost-effectiveness was much less favorable and was least favorable for younger patients ($130,000 for patients age <65, $100,000 for those age 65,74, and $96,000 for those age ,75). When we varied our assumptions from 50% to 200% of our baseline estimates in sensitivity analyses, results were most sensitive to the costs of the index hospitalization. CONCLUSIONS: For patients with relatively good short-term prognoses, we found that ventilator support and aggressive care were economically worthwhile, even for patients 75 years and older. For patients with poor short-term prognoses, ventilator support and aggressive care were much less cost-effective for adults of all ages. [source] CAPITALIZATION OF GOVERNMENT SUPPORT IN AGRICULTURAL LAND PRICES: WHAT DO WE KNOW?JOURNAL OF ECONOMIC SURVEYS, Issue 4 2009Laure Latruffe Abstract The objective of this paper is to provide an overview of existing literature, both theoretically and empirically, on the extent to which agricultural subsidies do translate into higher land values and rents and finally benefit landowners instead of agricultural producers. Our review shows that agricultural support policy instruments contribute to increasing the rental price of farmland, and that the extent of this increase closely depends on the level of the supply price elasticity of farmland relative to those of other factors/inputs on the one hand, and on the range of the possibilities of factor/input substitution in agricultural production on the other hand. The empirical literature shows that land prices and rents have in general a significant positive and inelastic response to government support. Such inelastic response is thought to reflect the uncertain future of the farm programmes. And in general, studies have indicated that land prices are more responsive to government-based returns than to market-based returns.

[source] DO PLASTID-RELATED CHARACTERS SUPPORT THE CHROMALVEOLATE HYPOTHESIS?,JOURNAL OF PHYCOLOGY, Issue 3 2005Andrzej Body According to the idea of secondary endosymbiosis, plastids with three and four envelope membranes have evolved from either red or green algal endosymbionts engulfed by phagotrophic protozoans. Although this hypothesis is nowadays commonly accepted, the number of secondary endosymbioses still remains controversial. One of the models, known as the "chromalveolate" hypothesis, postulates that the 4 membrane-bound plastids of Chromista and the 3 or 4 membrane-bound plastids of Alveolata result from a single secondary endosymbiosis involving a rhodophyte as the endosymbiont. Although this model has found many followers, a variety of data clearly contradict it. The ideas that became the direct inspiration for formulation of the "chromalveolate" hypothesis are also now questionable. In this comment, I discuss all these problems in the light of the most recent phylogenetic, cytological, and genomic data. [source] DECISION SUPPORT FOR ALLOCATION OF WATERSHED POLLUTION LOAD USING GREY FUZZY MULTIOBJECTIVE PROGRAMMING,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 3 2006Ho-Wen Chen ABSTRACT: This paper uses the grey fuzzy multiobjective programming to aid in decision making for the allocation of waste load in a river system under versatile uncertainties and risks. It differs from previous studies by considering a multicriteria objective function with combined grey and fuzzy messages under a cost benefit analysis framework. Such analysis technically integrates the prior information of water quality models, water quality standards, wastewater treatment costs, and potential benefits gained via in-stream water quality improvement. While fuzzy sets are characterized based on semantic and cognitive vagueness in decision making, grey numbers can delineate measurement errors in data collection. By employing three distinct set theoretic fuzzy operators, the synergy of grey and fuzzy implications may smoothly characterize the prescribed management complexity. With the aid of genetic algorithm in the solution procedure, the modeling outputs contribute to the development of an effective waste load allocation and reduction scheme for tributaries in this subwatershed located in the lower Tseng-Wen River Basin, South Taiwan. Research findings indicate that the inclusion of three fuzzy set theoretic operators in decision analysis may delineate different tradeoffs in decision making due to varying changes, transformations, and movements of waste load in association with land use pattern within the watershed. [source] GENTRIFICATION AND THE GRASSROOTS: POPULAR SUPPORT IN THE REVANCHIST SUBURBJOURNAL OF URBAN AFFAIRS, Issue 2 2006Christopher Niedt Drawing from a year of fieldwork in Dundalk, MD, I argue that developers and the neoliberal state will probably find popular support for gentrification as they reinvest in the politically divided industrial suburbs of the United States. Local homeowners and community associations have emerged as gentrification supporters for three interrelated reasons. First, many of them have drawn from a resurgent national conservatism to explain decline as an effect of government subsidies and "people from the city;" their desire to reclaim suburban space,a "suburban revanchism",although avoiding accusations of racism makes gentrification-induced displacement appealing. Second, the rebirth of urban neighborhoods and other industrial suburbs provides visual evidence of gentrification's success. Third, the neoliberal state's retreat from social programs and its emphasis on private-sector redevelopment allay suspicion of government and enable collaboration between the local state, developers, and homeowners. The redevelopment efforts of two local organizations illustrate how residents have become indispensable partners in Dundalk's emergent pro-gentrification coalition. [source] TRIVARIATE SUPPORT OF FLAT-VOLATILITY FORWARD LIBOR RATESMATHEMATICAL FINANCE, Issue 2 2010Farshid Jamshidian This paper investigates the multivariate support of forward Libor rates in the one-factor, constant volatilities Libor market model. The comparatively simple bivariate case was solved in Jamshidian (2008) in connection to the recent finding by Davis and Mataix-Pastor (2007) of positive probability of negative Libor rates in the swap market model. The approach here builds on Jamshidian (2008) but becomes really effective only in the trivariate case, and there particularly for a special "flat-volatility" case, leading to an analytic solution. The main idea is a certain recursion in the Libor market model by means of which the calculation of the support is reduced to a calculus of variation problem (with bounds on the slope). [source] BIVARIATE SUPPORT OF FORWARD LIBOR AND SWAP RATESMATHEMATICAL FINANCE, Issue 3 2008Farshid Jamshidian Based on a certain notion of "prolific process," we find an explicit expression for the bivariate (topological) support of the solution to a particular class of 2 × 2 stochastic differential equations that includes those of the three-period "lognormal" Libor and swap market models. This yields that in the lognormal swap market model (SMM), the support of the 1 × 1 forward Libor L*t equals [l*t, ,) for some semi-explicit ,1 ,l*t, 0, sharpening a result of Davis and Mataix-Pastor (2007) that forward Libor rates (eventually) become negative with positive probability in the lognormal SMM. We classify the instances l*t < 0, and explicitly calculate the threshold time at or before which L*t remains positive a.s. [source] WORK VALUE CONGRUENCE AND INTRINSIC CAREER SUCCESS: THE COMPENSATORY ROLES OF LEADER-MEMBER EXCHANGE AND PERCEIVED ORGANIZATIONAL SUPPORTPERSONNEL PSYCHOLOGY, Issue 2 2004BERRIN ERDOGAN We hypothesized that leader-member exchange (LMX) and perceived organizational support (POS) would each interact with work value congruence in relation to intrinsic career success. In a sample of 520 teachers from 30 high schools in Turkey, we found that work value congruence was positively related to job and career satisfaction when POS was low but not related to job and career satisfaction when POS was high. Similarly, work value congruence was positively related to career satisfaction when LMX was low but not related when LMX was high. The results contribute to the POS, LMX, and person-organization fit literatures by demonstrating the compensatory nature of LMX and POS for low value congruence in its relation to job and career satisfaction. [source] SOURCES OF SUPPORT AND EXPATRIATE PERFORMANCE: THE MEDIATING ROLE OF EXPATRIATE ADJUSTMENTPERSONNEL PSYCHOLOGY, Issue 1 2001MARIA L. KRAIMER This study examined the role of 3 sources of support in facilitating expatriate adjustment and performance. A model was developed that examined the effects of perceived organizational support (POS), leader-member exchange (LMX), and spousal support on expatriates' adjustment to work, the country, and interacting with foreign nationals. In turn, it was expected that expatriate adjustment would influence expatriate task performance and contextual performance. The model was tested using a sample of 213 expatriate-supervisor dyads via structural equation modeling. The results indicated that POS had direct effects on expatriate adjustment, which in turn had direct effects on both dimensions of performance. Although LMX did not influence adjustment, it did have direct effects on expatriate task and contextual performance. Spousal support did not relate to adjustment or performance. Practical implications for facilitating expatriate adjustment and performance are discussed. [source] Visual Support for Interactive Post-Interventional Assessment of Radiofrequency Ablation TherapyCOMPUTER GRAPHICS FORUM, Issue 3 2010Christian Rieder Abstract Percutaneous radiofrequency (RF) ablation is a minimally invasive, image-guided therapy for the treatment of liver tumors. The assessment of the ablation area (coagulation) is performed to verify the treatment success as an essential part of the therapy. Traditionally, pre- and post-interventional CT images are used to visually compare the shape, size, and position of tumor and coagulation. In this work, we present a novel visualization as well as a navigation tool, the so-called tumor map. The tumor map is a pseudo-cylindrical mapping of the tumor surface onto a 2D image. It is used for a combined visualization of all ablation zones of the tumor to allow a reliable therapy assessment. Additionally, the tumor map serves as an interactive tool for intuitive navigation within the 3D volume rendering of the tumor vicinity as well as with familiar 2D viewers. [source] Implicit Surface Modelling with a Globally Regularised Basis of Compact SupportCOMPUTER GRAPHICS FORUM, Issue 3 2006C. Walder We consider the problem of constructing a globally smooth analytic function that represents a surface implicitly by way of its zero set, given sample points with surface normal vectors. The contributions of the paper include a novel means of regularising multi-scale compactly supported basis functions that leads to the desirable interpolation properties previously only associated with fully supported bases. We also provide a regularisation framework for simpler and more direct treatment of surface normals, along with a corresponding generalisation of the representer theorem lying at the core of kernel-based machine learning methods. We demonstrate the techniques on 3D problems of up to 14 million data points, as well as 4D time series data and four-dimensional interpolation between three-dimensional shapes.

The questionnaire asked about methods used for auditory examination, developmental surveillance and identification of disturbances in mother-child interaction. Activities for health promotion concerning breastfeeding, non-smoking and allergy prevention were also queried. Thirty-four CMOs representing 1731 CHCs and 645000 children answered the questionnaire. The reply rate was 81%. Various methods of auditory examination are offered all infants and children in Sweden. The national guidelines for health supervision are followed fairly closely by all. Screening for disturbances in attention, motor development and perception (DAMP) is performed by all but four districts, with various methods, resources and degrees of co-operation with school health services. Support in mother-child interaction is considered very important and new methods to identify and treat disturbances are gradually introduced. Breastfeeding is encouraged; breast milk is the main source of food for 67% of babies at 4 mo of age. Activities to stop or diminish use of tobacco are ongoing everywhere, as are programmes to identify children at risk of developing allergies and for allergy prevention. Thus, the Child Health Services maintain a high standard and are ambitious about introducing new methods and ideas. [source] GOLD infrastructure for virtual organizationsCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 11 2008P. Periorellis Abstract The paper discusses the GOLD project (Grid-based Information Models to Support the Rapid Innovation of New High Value-Added Chemicals) whose principal aim is to carry out research and development into enabling technologies to support the formation, operation and termination of virtual organizations. The paper discusses the outcome of this research, which is the GOLD Middleware infrastructure. The infrastructure has been implemented in the form of a set of Middleware components, which address issues such as trust, security, contract monitoring and enforcement, information management and coordination. We discuss all these issues in turn and more importantly we demonstrate how current WS standards can be used to implement these issues. In addition, the paper follows a top down approach starting with a brief outline on the architectural elements derived during the requirements engineering phase and demonstrates how these elements were mapped onto actual services that were implemented according to service-oriented architecture principles and related technologies.

[source] Extended Mechanical Circulatory Support With a Continuous-Flow Rotary Left Ventricular Assist DeviceCONGESTIVE HEART FAILURE, Issue 2 2010Scott Harris DO Background LVAD therapy is an established treatment modality for patients with advanced heart failure. Pulsatile LVADs have limitations in design precluding their use for extended support. Continuous-flow rotary LVADs represent an innovative design with potential for small size and greater reliability by simplification of the pumping mechanism. Methods In a prospective multicenter study, 281 patients urgently listed (United Network for Organ Sharing status 1A or 1B) for heart transplant underwent implant of a continuous-flow LVAD. Survival and transplant rates were assessed at 18 months. Patients were assessed for adverse events throughout the study and for quality of life, functional status, and organ function for 6 months. Results Of 281 patients, 222 (79%) underwent transplant or LVAD removal for cardiac recovery or had ongoing LVAD support at 18-month follow-up. Actuarial survival on support was 72% (95% confidence interval, 65%,79%) at 18 months. At 6 months, there were significant improvements in functional status and 6-minute walk test results (from 0% to 83% of patients in New York Heart Association functional class I or II and from 13% to 89% of patients completing a 6-minute walk test) and in quality of life (mean values improved 41% with Minnesota Living With Heart Failure and 75% with Kansas City Cardiomyopathy questionnaires). Major adverse events included bleeding, stroke, right heart failure, and percutaneous lead infection. Pump thrombosis occurred in 4 patients. Conclusions A continuous-flow LVAD provides effective hemodynamic support for at least 18 months in patients awaiting transplant, with improved functional status and quality of life.

The authors report their current VAD weaning protocol. Between 2003 and 2006, 38 patients received VAD implants. The authors performed 5 tests in 4 patients in whom echocardiography findings suggested myocardial recovery after implant. The protocol consists of assessing symptoms, electrocardiographic findings, hemodynamics, and cardiac function at baseline and as VAD support is weaned. As a result, 3 patients passed the weaning protocol and were explanted. There has been no recurrence of heart failure 667, 752, and 1007 days after explant, respectively. One patient failed the protocol after 151 days of support because of low cardiac index during the protocol. This patient was transplanted. This current experience of VAD weaning protocol is a novel tool to identify candidates for successful VAD explantation. [source] Improving Heart Failure Self-Management Support by Actively Engaging Out-of-Home Caregivers: Results of a Feasibility StudyCONGESTIVE HEART FAILURE, Issue 1 2008John D. Piette PhD The benefits of heart failure (HF) care management have been demonstrated, yet health systems are often unable to meet patients' needs for support between outpatient visits. Informal care provided by family or friends is a low-cost, and potentially effective, adjunct to care management services. The authors evaluated the feasibility of augmenting HF care management with weekly, automated assessment and behavior change calls to patients, feedback via the Internet to an out-of-home informal caregiver or CarePartner (CP), and faxes to the patient's health care team. The program included 52 HF patient-CP pairs participating for an average of 12 weeks. Patients completed 586 assessments (92% completion rate) and reported problems that might otherwise have gone unidentified. At follow-up, 75% had made changes in their self-care as a result of the intervention. The CP program may extend the impact of HF telemonitoring beyond what care management programs can realistically deliver. [source] Myocardial Perfusion As Assessed by Positron Emission Tomography During Long-Term Mechanical Circulatory SupportCONGESTIVE HEART FAILURE, Issue 2 2006George V. Letsou MD Although mechanical circulatory support (MCS) can improve myocardial function in patients with advanced heart failure, its effects on relative myocardial perfusion are unclear. Using positron emission tomographic imaging techniques, the authors assessed relative myocardial perfusion in patients with ischemic or idiopathic cardiomyopathy who were receiving chronic MCS with a left ventricular assist device (pulsatile HeartMate [n=2] [Thoratec Corporation, Pleasanton, CA] or nonpulsatile Jarvik 2000 [n=4] [Jarvik Heart, Inc., New York, NY]). Relative myocardial perfusion was compared at lower and higher levels of MCS (50 vs. 100,110 ejections/min for the HeartMate and 8000 vs. 12,000 rpm for the Jarvik 2000). The size and severity of perfusion defects at rest and after dipyridamole stress were measured objectively and subjectively by computer algorithms and visual inspection, respectively. Relative myocardial perfusion increased >5% from baseline in only one of six patients when MCS was increased. No change in relative myocardial perfusion of >5% was seen in any of the other five patients, even after subsequent dipyridamole stress positron emission tomographic imaging. These pilot study findings suggest that the decreased metabolic requirements induced by ventricular unloading correspondingly decreased blood flow requirements to physiologically inactive myocardium.

[source] Senior Management Support in the New Product Development ProcessCREATIVITY AND INNOVATION MANAGEMENT, Issue 4 2001Jorge Gomes This paper studies the relationship between senior management support to new product development activities by means of a quantitative and qualitative analysis of questionnaire and interview data collected in the United Kingdom and the Netherlands. The quantitative analysis showed that there is a small to medium association between senior management support to new product development and project performance in the dimensions of time, cost, and end product quality. The qualitative analysis suggests that these weak links could be explained by separating the influence of senior management support on new product development activities into direct and indirect effects. Direct effects include issues such as the use of multifunctional senior teams and process champions, whereas indirect effects include issues such as organization mission and goals, and learning and knowledge management systems. [source] Functional consistency across two behavioural modalities: fire-setting and self-harm in female special hospital patientsCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 1 2007Sarah Miller Background,Fire-setting and self-harm behaviours among women in high security special hospitals may be understood using Shye's Action System Theory (AST) in which four functional modes are recognized: ,adaptive', ,expressive', ,integrative', and ,conservative'. Aims,To test for relationships between different forms of fire-setting and self-harm behaviours and AST modes among women in special hospital, and for consistency within modes across the two behaviours. Method,Clinical case files evidencing both fire-setting and self-harm behaviours (n = 50) were analysed for content, focusing on incident characteristics. A total of 29 fire-setting and 22 self-harm variables were analysed using Smallest Space Analysis (SSA). Chi-square and Spearman's rho (,) analyses were used to determine functional consistency across behavioural modes. Results,Most women showed one predominant AST mode in fire-setting (n = 39) and self-harm (n = 35). Significant positive correlations were found between integrative and adaptive modes of functioning. The lack of correlation between conservative and expressive modes reflects the differing behaviours used in each activity. Despite this, significant cross-tabulations revealed that each woman had parallel fire-setting and self-harm styles. Discussion,Findings suggest that, for some women, setting fires and self harm fulfil a similar underlying function. Support is given to AST as a way of furthering understanding of damaging behaviours, whether self- or other-inflicted. Copyright © 2007 John Wiley & Sons, Ltd. [source] The Decision of the Supply Chain Executive to Support or Impede Supply Chain Integration: A Multidisciplinary Behavioral Agency Perspective,DECISION SCIENCES, Issue 4 2009Verónica H. Villena ABSTRACT Applying the behavioral agency model developed by Wiseman and Gomez-Mejia (1998), this article analyzes human resource factors that induce supply chain executives (SCEs) to make decisions that foster or hinder supply chain integration. We examine two internal sources (compensation and employment risk) and one external source (environmental volatility) of risk bearing that can make SCEs more reluctant to make the decision to promote supply chain integration. We argue and empirically confirm the notion that an employment and compensation system that increases SCE risk bearing reduces the SCE's willingness to make risky decisions and thus discourages supply chain integration. We also reveal that this negative relationship becomes stronger under conditions of high environmental volatility. In addressing the "so what?" question, we found empirical support for the hypothesis that supply chain integration positively influences operational performance. Even though this decision has a positive value for the firm, we showed that SCEs discourage supply chain integration when they face higher risk bearing. Hypotheses are tested using a combination of primary survey data and archival measures in a sample of 133 Spanish firms. [source] | ||||||||||||||||||||||||||||||||||
