  1. Trust in the context of management relationships: an empirical study.

    OpenAIRE

    Atkinson, Sally; Butcher, David

    2003-01-01

    This paper responds to calls for exploration of the dynamics of trust in the embedded context of interpersonal managerial relationships. Building on theoretical distinctions between different types of interpersonal relationships established in social psychology, the paper proposes a generic typology of interpersonal managerial relationships, along with associated hypotheses and implications for trust. The later part of the paper then reports the results from an initial explorat...

    Full Text Available The purpose of this exploratory research study is to examine the extent of recognition of the concept of intellectual capital in the Tunisian context and to identify the perceptions of managers concerning the accounting treatment and disclosure of this hidden concept. A survey questionnaire was conducted among 51 Tunisian managers. The results of this survey argue that the majority of respondents perceive the elements of intellectual capital as important value drivers for their business. This study shows that managers are aware of the shortcoming of the present accounting system and they approve previous studies that propose voluntary disclosure of information relating to intellectual capital as a solution to compensate for the loss of relevance of traditional accounting information. The present study presents a significant interest in the accounting literature and provides whether it would be appropriate for the Tunisian accounting standard setter to ask companies to disclose more intellectual capital information.

  5. Empirical ethics, context-sensitivity, and contextualism.

    Science.gov (United States)

    Musschenga, Albert W

    2005-10-01

    In medical ethics, business ethics, and some branches of political philosophy (multi-culturalism, issues of just allocation, and equitable distribution) the literature increasingly combines insights from ethics and the social sciences. Some authors in medical ethics even speak of a new phase in the history of ethics, hailing "empirical ethics" as a logical next step in the development of practical ethics after the turn to "applied ethics." The name empirical ethics is ill-chosen because of its associations with "descriptive ethics." Unlike descriptive ethics, however, empirical ethics aims to be both descriptive and normative. The first question on which I focus is what kind of empirical research is used by empirical ethics and for which purposes. I argue that the ultimate aim of all empirical ethics is to improve the context-sensitivity of ethics. The second question is whether empirical ethics is essentially connected with specific positions in meta-ethics. I show that in some kinds of meta-ethical theories, which I categorize as broad contextualist theories, there is an intrinsic need for connecting normative ethics with empirical social research. But context-sensitivity is a goal that can be aimed for from any meta-ethical position.

  8. An empirical study of rape in the context of multiple murder.

    Science.gov (United States)

    DeLisi, Matt

    2014-03-01

    In recent years, multiple homicide offending has received increased research attention from criminologists; however, there is mixed evidence about the role of rape toward the perpetration of multiple murder. Drawing on criminal career data from a nonprobability sample of 618 confined male homicide offenders selected from eight U.S. states, the current study examines the role of rape as a predictor of multiple homicide offending. Bivariate analyses indicated a significant association between rape and murder charges. Multivariate path regression models indicated that rape had a significant and robust association with multiple murder. This relationship withstood the confounding effects of kidnapping, prior prison confinement, and prior murder, rape, and kidnapping. These results provide evidence that rape potentially serves as a gateway to multiple murder for some serious offenders. Suggestions for future research are proffered.

    2006-01-01

    Full Text Available Abstract Background Economic valuations of health care programs often require using patients as subjects, implying that research methodology should conform to the surrounding social, cultural and ethical context. The significance of patients' opinions in health care decisions has been well defined but in Greece, and perhaps elsewhere, clinicians remain skeptical. The purpose of this study was to investigate, for the first time in Greece, the feasibility of measuring preference-based health-state utilities and willingness to pay and to determine the context-based adaptations required to overcome inherent elicitation problems. Methods A survey including a time trade-off (TTO, a standard gamble (SG, and two willingness-to-pay (WTP questions was self-administered to a homogenous group of 606 end stage renal disease patients in 24 dialysis facilities throughout Greece and the overall response rate was 78.5%. Typical elicitation methods were adapted to overcome methodological problems such as subjective life expectancy and question framing. Spearman's correlation coefficients were calculated between utilities and WTP and parametric tests (independent samples t-test and ANOVA examined score differences as a result of demographic and clinical factors. Results Mean health-state utilities were 72.56 (TTO and 91.06 (SG and these were statistically significantly different (P P P P P P P Conclusion This study demonstrated, to a fair extent, that adapting research methods to context-based particularities does not necessarily compromise results and should be considered in situations where standard methods cannot be applied. On the other hand, it is emphasized that the results from this study are preliminary and should be interpreted cautiously until further research demonstrates the practicality, reliability and validity of alternative measurement approaches.

  13. Capitalist contexts for Darwinian theory: land, finance, industry and empire.

    Science.gov (United States)

    Hodge, M J S

    2009-01-01

    When socio-economic contexts are sought for Darwin's science, it is customary to turn to the Industrial Revolution. However, important issues about the long run of England's capitalisms can only be recognised by taking a wider view than Industrial Revolution historiographies tend to engage. The role of land and finance capitalisms in the development of the empire is one such issue. If we historians of Darwin's science allow ourselves a distinction between land and finance capitalisms on the one hand and industrial capitalism on the other; and if we ask with which side of this divide were Darwin and his theory of branching descent by natural selection aligned, then reflection on leading features of that theory, including its Malthusian elements, suggests that the answer is often and largely, though not exclusively: on the land side. The case of Wallace, socialist opponent of land capitalism, may not be as anomalous for this suggestion as one might at first think. Social and economic historians have reached no settled consensuses on the long-run of England's capitalisms. We historians of Darwin's science would do well to import some of these unsettled states of discussion into our own work over the years to come.

    Full Text Available The general aim of the research was to theoretically and empirically study and evaluate job and family stressors amongst firefighters in the South African context. This also included an empirical evaluation of the stress symptoms of firefighters. The research was quantitative, consisting of a survey design. Three measuring instruments were used, namely the Experience of Work and Life Circumstances questionnaire, the Stress questionnaire as well as a biographical questionnaire. Task characteristics, organisational functioning, physical working conditions and job equipment, career and social matters, remuneration, fringe benefits and personnel policy were identified as causes of job stress originating within the work situation. Marital dysfunction and divorce, limited time with the family, problems with children, alcohol and drug abuse, lack of exercise, suicide, anger aimed at family members, physical and emotional exhaustion, lonely marital partners, unavailability to help the family when needed and depression were identified as causes of family stress arising outside the work situation.

    Science.gov (United States)

    Bresina, John L.; Khatib, Lina; McGann, Conor

    2006-01-01

    This paper presents an empirical study of some nonexhaustive approaches to optimizing preferences within the context of constraint-based, mixed-initiative planning for mission operations. This work is motivated by the experience of deploying and operating the MAPGEN (Mixed-initiative Activity Plan GENerator) system for the Mars Exploration Rover Mission. Responsiveness to the user is one of the important requirements for MAPGEN, hence, the additional computation time needed to optimize preferences must be kept within reasonabble bounds. This was the primary motivation for studying non-exhaustive optimization approaches. The specific goals of rhe empirical study are to assess the impact on solution quality of two greedy heuristics used in MAPGEN and to assess the improvement gained by applying a linear programming optimization technique to the final solution.

    As part of an ongoing study on mobile systems development (MSD), this paper presents preliminary findings of research-in-progress. The debate on mobility in research has so far been dominated by mobile HCI, technological innovations, and socio-technical issues related to new and emerging mobile...... work patterns. This paper is about the development of mobile systems.Based on an on-going empirical study I present four case studies of companies each with different products or services to offer and diverging ways of establishing and sustaining a successful business in the mobile industry. From...... the case studies I propose a five-layered framework for understanding the structure and segmentation of the industry. This leads to an analysis of the different modes of operation within the mobile industry, exemplified by the four case studies.The contribution of this paper is therefore two-fold: (1) I...

    To conduct a concept analysis of clinical practice contexts (work environments) that facilitate or militate against the uptake of research evidence by healthcare professionals in clinical practice. This will involve developing a clear definition of context by describing its features, domains and defining characteristics. The context where clinical care is delivered influences that care. While research shows that context is important to knowledge translation (implementation), we lack conceptual clarity on what is context, which contextual factors probably modify the effect of knowledge translation interventions (and hence should be considered when designing interventions) and which contextual factors themselves could be targeted as part of a knowledge translation intervention (context modification). Concept analysis. The Walker and Avant concept analysis method, comprised of eight systematic steps, will be used: (1) concept selection; (2) determination of aims; (3) identification of uses of context; (4) determination of defining attributes of context; (5) identification/construction of a model case of context; (6) identification/construction of additional cases of context; (7) identification/construction of antecedents and consequences of context; and (8) definition of empirical referents of context. This study is funded by the Canadian Institutes of Health Research (January 2014). This study will result in a much needed framework of context for knowledge translation, which identifies specific elements that, if assessed and used to tailor knowledge translation activities, will result in increased research use by nurses and other healthcare professionals in clinical practice, ultimately leading to better patient care. © 2014 John Wiley & Sons Ltd.

    2014-10-01

    Full Text Available The future is uncertain, but management needs to determine and also be informed about possible change trends. This research, however, reports on empirical results of the views of South African HRM practitioners to identify and prioritise business change trends for 2002 and 2010 in terms of the “hard” or “soft” HRM debate in the literature. All organisations employing HRM practitioners were include and a total of 1640 questionnaires were distributed resulting in 207 useable responses.   The results highlight trends such as increased international competition, globalisation and inadequate skills in different rankings for 2002 and 2010. It is concluded that HRM practitioners, are influenced by the “hard” or “soft” approach, when they participate in a strategic management context in organisations.

  11. Equifinality in empirical studies of cultural transmission.

    Science.gov (United States)

    Barrett, Brendan J

    2018-01-31

    Cultural systems exhibit equifinal behavior - a single final state may be arrived at via different mechanisms and/or from different initial states. Potential for equifinality exists in all empirical studies of cultural transmission including controlled experiments, observational field research, and computational simulations. Acknowledging and anticipating the existence of equifinality is important in empirical studies of social learning and cultural evolution; it helps us understand the limitations of analytical approaches and can improve our ability to predict the dynamics of cultural transmission. Here, I illustrate and discuss examples of equifinality in studies of social learning, and how certain experimental designs might be prone to it. I then review examples of equifinality discussed in the social learning literature, namely the use of s-shaped diffusion curves to discern individual from social learning and operational definitions and analytical approaches used in studies of conformist transmission. While equifinality exists to some extent in all studies of social learning, I make suggestions for how to address instances of it, with an emphasis on using data simulation and methodological verification alongside modern statistical approaches that emphasize prediction and model comparison. In cases where evaluated learning mechanisms are equifinal due to non-methodological factors, I suggest that this is not always a problem if it helps us predict cultural change. In some cases, equifinal learning mechanisms might offer insight into how both individual learning, social learning strategies and other endogenous social factors might by important in structuring cultural dynamics and within- and between-group heterogeneity.

  12. Empirical study of supervised gene screening

    Full Text Available Abstract Background Microarray studies provide a way of linking variations of phenotypes with their genetic causations. Constructing predictive models using high dimensional microarray measurements usually consists of three steps: (1 unsupervised gene screening; (2 supervised gene screening; and (3 statistical model building. Supervised gene screening based on marginal gene ranking is commonly used to reduce the number of genes in the model building. Various simple statistics, such as t-statistic or signal to noise ratio, have been used to rank genes in the supervised screening. Despite of its extensive usage, statistical study of supervised gene screening remains scarce. Our study is partly motivated by the differences in gene discovery results caused by using different supervised gene screening methods. Results We investigate concordance and reproducibility of supervised gene screening based on eight commonly used marginal statistics. Concordance is assessed by the relative fractions of overlaps between top ranked genes screened using different marginal statistics. We propose a Bootstrap Reproducibility Index, which measures reproducibility of individual genes under the supervised screening. Empirical studies are based on four public microarray data. We consider the cases where the top 20%, 40% and 60% genes are screened. Conclusion From a gene discovery point of view, the effect of supervised gene screening based on different marginal statistics cannot be ignored. Empirical studies show that (1 genes passed different supervised screenings may be considerably different; (2 concordance may vary, depending on the underlying data structure and percentage of selected genes; (3 evaluated with the Bootstrap Reproducibility Index, genes passed supervised screenings are only moderately reproducible; and (4 concordance cannot be improved by supervised screening based on reproducibility.

    MacEachren, A M; Roth, R E; O'Brien, J; Li, B; Swingley, D; Gahegan, M

    2012-12-01

    This paper presents two linked empirical studies focused on uncertainty visualization. The experiments are framed from two conceptual perspectives. First, a typology of uncertainty is used to delineate kinds of uncertainty matched with space, time, and attribute components of data. Second, concepts from visual semiotics are applied to characterize the kind of visual signification that is appropriate for representing those different categories of uncertainty. This framework guided the two experiments reported here. The first addresses representation intuitiveness, considering both visual variables and iconicity of representation. The second addresses relative performance of the most intuitive abstract and iconic representations of uncertainty on a map reading task. Combined results suggest initial guidelines for representing uncertainty and discussion focuses on practical applicability of results.

  14. Context, Experience, Expectation, and Action—Towards an Empirically Grounded, General Model for Analyzing Biographical Uncertainty

    Directory of Open Access Journals (Sweden)

    Herwig Reiter

    2010-01-01

    Full Text Available The article proposes a general, empirically grounded model for analyzing biographical uncertainty. The model is based on findings from a qualitative-explorative study of transforming meanings of unemployment among young people in post-Soviet Lithuania. In a first step, the particular features of the uncertainty puzzle in post-communist youth transitions are briefly discussed. A historical event like the collapse of state socialism in Europe, similar to the recent financial and economic crisis, is a generator of uncertainty par excellence: it undermines the foundations of societies and the taken-for-grantedness of related expectations. Against this background, the case of a young woman and how she responds to the novel threat of unemployment in the transition to the world of work is introduced. Her uncertainty management in the specific time perspective of certainty production is then conceptually rephrased by distinguishing three types or levels of biographical uncertainty: knowledge, outcome, and recognition uncertainty. Biographical uncertainty, it is argued, is empirically observable through the analysis of acting and projecting at the biographical level. The final part synthesizes the empirical findings and the conceptual discussion into a stratification model of biographical uncertainty as a general tool for the biographical analysis of uncertainty phenomena.

  15. Evolution of viral virulence: empirical studies

    Science.gov (United States)

    Kurath, Gael; Wargo, Andrew R.

    2016-01-01

    The concept of virulence as a pathogen trait that can evolve in response to selection has led to a large body of virulence evolution theory developed in the 1980-1990s. Various aspects of this theory predict increased or decreased virulence in response to a complex array of selection pressures including mode of transmission, changes in host, mixed infection, vector-borne transmission, environmental changes, host vaccination, host resistance, and co-evolution of virus and host. A fundamental concept is prediction of trade-offs between the costs and benefits associated with higher virulence, leading to selection of optimal virulence levels. Through a combination of observational and experimental studies, including experimental evolution of viruses during serial passage, many of these predictions have now been explored in systems ranging from bacteriophage to viruses of plants, invertebrates, and vertebrate hosts. This chapter summarizes empirical studies of viral virulence evolution in numerous diverse systems, including the classic models myxomavirus in rabbits, Marek's disease virus in chickens, and HIV in humans. Collectively these studies support some aspects of virulence evolution theory, suggest modifications for other aspects, and show that predictions may apply in some virus:host interactions but not in others. Finally, we consider how virulence evolution theory applies to disease management in the field.

    2012-04-01

    Full Text Available The personality of an entrepreneur is one of the most important characteristics of reaching success by creating jobs and opportunities. In this paper, we demonstrate an empirical study on personal characteristics of students who are supposed to act as entrepreneur to create jobs in seven fields of accounting, computer science, mechanical engineering, civil engineering, metallurgy engineering, electrical engineering and drawing. There are seven aspects of accepting reasonable risk, locus of control, the need for success, mental health conditions, being pragmatic, tolerating ambiguity, dreaming and the sense of challenging in our study to measure the level of entrepreneurship. We uniformly distribute 133 questionnaires among undergraduate students in all seven groups and analyze the results based on t-student test. Our investigation indicates that all students accept reasonable amount of risk, they preserve sufficient locus of control and they are eager for success. In addition, our tests indicate that students believe they maintain sufficient level of mental health care with strong sense of being pragmatic and they could handle ambiguity and challenges.

    Science.gov (United States)

    Sundell, Knut; Ferrer-Wreder, Laura; Fraser, Mark W

    2014-06-01

    The spread of evidence-based practice throughout the world has resulted in the wide adoption of empirically supported interventions (ESIs) and a growing number of controlled trials of imported and culturally adapted ESIs. This article is informed by outcome research on family-based interventions including programs listed in the American Blueprints Model and Promising Programs. Evidence from these controlled trials is mixed and, because it is comprised of both successful and unsuccessful replications of ESIs, it provides clues for the translation of promising programs in the future. At least four explanations appear plausible for the mixed results in replication trials. One has to do with methodological differences across trials. A second deals with ambiguities in the cultural adaptation process. A third explanation is that ESIs in failed replications have not been adequately implemented. A fourth source of variation derives from unanticipated contextual influences that might affect the effects of ESIs when transported to other cultures and countries. This article describes a model that allows for the differential examination of adaptations of interventions in new cultural contexts. © The Author(s) 2012.

  20. Successful intelligence and giftedness: an empirical study

    Full Text Available The aim of our research is to look into the diversity within gifted and talented students. This is important to better understand their complexity and thus offer a more appropriate educational programs. There are rather few empirical works which attempt to identify high abilities profiles (giftedness and talent that actually exist beyond the theoretical level. The present work intends to single out the different patterns or profiles resulting from the combination of the successful intelligence abilities (analytical, synthetic and practical, as defined by Stenberg. A total of 431 students from the Region of Murcia participated in this study. These students performed the Aurora Battery tasks (Chart, Grigorenko, & Sternberg, 2008, designed to measure the analytical, practical and creative intelligence. Analytically gifted students (n=27, practically gifted (n=33 and creatively gifted (n= 34 were identified, taking as criteria scores equal to or higher than 120 IQ on each intelligence. Different Q-factor analyses were carried out for the three groups of students, in such a way that students were grouped according to their similarities. A total of 10 profiles showing how successful intelligence abilities are combined were obtained, something that has made possible to support the theory put forward by Sternberg (2000: the analytical, practical and creative talent profiles, as well as the resulting combinations, the analytical-practical, analytical-creative, practical-creative profiles, along with the consummate balance talent (high performance in the three types of intelligence.

    Full Text Available The present study is focused on investigating the relationship between intentional governance mechanisms (Directors’ boards, Ownership structure and audit quality and financial communication transparency. For this purpose, a model is used and applied to Tunisian firms’ sample observed over the period 2006–2013. The achieved results reveal that intentional governance mechanisms are positively related to a higher transparency level noticeable in financial communication (voluntary disclosure and quality information. In addition, empirical tests indicate that financial communication transparency is highly dependent on the board size, ownership concentration, as well as on audit quality.

  2. A study on online monitoring system development using empirical models

    Maintenance technologies have been progressed from a time-based to a condition-based manner. The fundamental idea of condition-based maintenance (CBM) is built on the real-time diagnosis of impending failures and/or the prognosis of residual lifetime of equipment by monitoring health conditions using various sensors. The success of CBM, therefore, hinges on the capability to develop accurate diagnosis/prognosis models. Even though there may be an unlimited number of methods to implement models, the models can normally be classified into two categories in terms of their origins: using physical principles or historical observations. I have focused on the latter method (sometimes referred as the empirical model based on statistical learning) because of some practical benefits such as context-free applicability, configuration flexibility, and customization adaptability. While several pilot-scale systems using empirical models have been applied to work sites in Korea, it should be noticed that these do not seem to be generally competitive against conventional physical models. As a result of investigating the bottlenecks of previous attempts, I have recognized the need for a novel strategy for grouping correlated variables such that an empirical model can accept not only statistical correlation but also some extent of physical knowledge of a system. Detailed examples of problems are as follows: (1) missing of important signals in a group caused by the lack of observations, (2) problems of signals with the time delay, (3) problems of optimal kernel bandwidth. In this study an improved statistical learning framework including the proposed strategy and case studies illustrating the performance of the method are presented.

  3. Empirical Performance of Cross-Validation With Oracle Methods in a Genomics Context.

    When employing model selection methods with oracle properties such as the smoothly clipped absolute deviation (SCAD) and the Adaptive Lasso, it is typical to estimate the smoothing parameter by m-fold cross-validation, for example, m = 10. In problems where the true regression function is sparse and the signals large, such cross-validation typically works well. However, in regression modeling of genomic studies involving Single Nucleotide Polymorphisms (SNP), the true regression functions, while thought to be sparse, do not have large signals. We demonstrate empirically that in such problems, the number of selected variables using SCAD and the Adaptive Lasso, with 10-fold cross-validation, is a random variable that has considerable and surprising variation. Similar remarks apply to non-oracle methods such as the Lasso. Our study strongly questions the suitability of performing only a single run of m-fold cross-validation with any oracle method, and not just the SCAD and Adaptive Lasso.

    Full Text Available This paper looks at the topic of regulation of integrated reporting for listed companies, with the aim of contributing to the debate on the usefulness of introducing a mandatory regime, both from the perspective of integrated performance sustainability of companies and from that of relevance of information for providers of financial capital. The study is based on empirical research carried out on a sample composed of companies operating in territories where the adoption of integrated reporting is voluntary (Europe and those operating in a country where adoption is mandatory (South Africa. The research shows that (a in voluntary regimes, levels of integrated performance achieved by companies are higher; (b mandatory regulation produces positive effects on integrated performance levels in the medium term; (c integrated performance indicators are value-relevant, though having different levels of relevance under the two regimes examined.

  6. Empirical studies on changes in oil governance

    Science.gov (United States)

    Kemal, Mohammad

    Regulation of the oil and gas sector is consequential to the economies of oil-producing countries. In the literature, there are two types of regulation: indirect regulation through taxes and tariffs or direct regulation through the creation of a National Oil Company (NOC). In the 1970s, many oil-producing countries nationalized their oil and gas sectors by creating and giving ownership rights of oil and gas resources to NOCs. In light of the success of Norway in regulating its oil and gas resources, over the past two decades several countries have changed their oil governance by changing the rights given to NOC from ownership right to mere access rights like other oil companies. However, empirical literature on these changes in oil governance is quite thin. Thus, this dissertation will explore three research questions to investigate empirically these changes in oil governance. First, I investigate empirically the impact of the changes in oil governance on aggregate domestic income. By employing a difference-in-difference method, I will show that a country which changed its oil governance increases its GDP per-capita by 10%. However, the impact is different for different types of political institution. Second, by observing the changes in oil governance in Indonesia , I explore the impact of the changes on learning-by-doing and learning spillover effect in offshore exploration drilling. By employing an econometric model which includes interaction terms between various experience variables and changes in an oil governance dummy, I will show that the change in oil governance in Indonesia enhances learning-by-doing by the rigs and learning spillover in a basin. Lastly, the impact of the changes in oil governance on expropriation risk and extraction path will be explored. By employing a difference-in-difference method, this essay will show that the changes in oil governance reduce expropriation and the impact of it is different for different sizes of resource stock.

  7. Trade liberalization, social policies and health: an empirical case study.

    This study investigates the health impacts of a major liberalization episode in the textile and clothing (T&C) sector. This episode triggered substantial shifts in employment across a wide range of countries. It is the first study to empirically link trade liberalization to health via changes in employment and offers some of the first empirical insights on how trade liberalization interacts with social policies to influence health. Data from 32 T&C reliant countries were analysed in reference to the pre- and post-liberalization periods of 2000-2004 and 2005-2009. Fuzzy-set qualitative comparative analysis (fsQCA) was used to examine the association between countries' a) level of development b) labour market and welfare state protections c) T&C employment changes and d) changes in adult female and infant mortality rates. Process tracing was used to further investigate these associations through twelve in-depth country studies. Results from the fsQCA relate changes in employment after the phase-out to both changing adult female and infant mortality rates. Findings from the in-depth country studies suggest that the worsening of adult female mortality rates is related to workers' lack of social protection, both in the context of T&C employment growth and loss. Overall, it is found that social protection is often inaccessible to the type of workers who may be the most vulnerable to processes of liberalization and that many workers are particularly vulnerable due to the structure of social protection policies. Social policies are therefore found to both moderate pathways to health and influence the type of health-related pathways resulting from trade liberalizing policies.

  8. Assessing the empirical validity of alternative multi-attribute utility measures in the maternity context

    Full Text Available Abstract Background Multi-attribute utility measures are preference-based health-related quality of life measures that have been developed to inform economic evaluations of health care interventions. The objective of this study was to compare the empirical validity of two multi-attribute utility measures (EQ-5D and SF-6D based on hypothetical preferences in a large maternity population in England. Methods Women who participated in a randomised controlled trial of additional postnatal support provided by trained community support workers represented the study population for this investigation. The women were asked to complete the EQ-5D descriptive system (which defines health-related quality of life in terms of five dimensions: mobility, self care, usual activities, pain/discomfort and anxiety/depression and the SF-36 (which defines health-related quality of life, using 36 items, across eight dimensions: physical functioning, role limitations (physical, social functioning, bodily pain, general health, mental health, vitality and role limitations (emotional at six months postpartum. Their responses were converted into utility scores using the York A1 tariff set and the SF-6D utility algorithm, respectively. One-way analysis of variance was used to test the hypothetically-constructed preference rule that each set of utility scores differs significantly by self-reported health status (categorised as excellent, very good, good, fair or poor. The degree to which EQ-5D and SF-6D utility scores reflected alternative dichotomous configurations of self-reported health status and the Edinburgh Postnatal Depression Scale score was tested using the relative efficiency statistic and receiver operating characteristic (ROC curves. Results The mean utility score for the EQ-5D was 0.861 (95% CI: 0.844, 0.877, whilst the mean utility score for the SF-6D was 0.809 (95% CI: 0.796, 0.822, representing a mean difference in utility score of 0.052 (95% CI: 0.040, 0

    2016-12-01

    Full Text Available The article deals with the formation of students’ mathematical competence in higher humanitarian education. The scientific literature analysis and pedagogical experience has shown that in spite of the numerous studies conducted in this area, the idea of coupling mathematical education of the humanitarians with their cultural, methodological and professional training remains. In our opinion, the design of mathematical training of the humanitarians must rely on the theory of activity, which brings together the main statements of methodology, pedagogy, psychology, such as the principles and methods of teaching, the problems of the peculiarities of students’ thinking, the increase of the level of their cognitive activity, the person’s education as a whole.The article presents the components of mathematical competence, criteria indicators, stages and levels of its formation. For the formation of mathematical competence it is proposed to apply context- empirical approach and developed on the basis of its organizational and pedagogical model (the main elements of this model are described in the article. In conclusion the pedagogical conditions of effective formation of mathematical competence in students in the system profile of humanitarian education are highlighted and revealed.

  12. Empirical studies of regulatory restructuring and incentives

    Science.gov (United States)

    Knittel, Christopher Roland

    This dissertation examines the actions of firms when faced with regulatory restructuring. Chapter I examines the equilibrium pricing behavior of local exchange telephone companies under a variety of market structures. In particular, the pricing behavior of three services are analyzed: residential local service, business local service, and intraLATA toll service. Beginning in 1984, a variety of market structure changes have taken place in the local telecommunications industry. I analyze differences in the method of price-setting regulation and the restrictions on entry. Specifically, the relative pricing behavior under rate of return and price cap regulation is analyzed, as well as the impact of entry in the local exchange and intraLATA toll service markets. In doing so, I estimate an empirical model that accounts for the stickiness of rates in regulated industries that is based on firm and regulator decision processes in the presence of adjustment costs. I find that, faced with competitive pressures that reduce rates in one service, incumbent firm rates increase in other services, thereby reducing the benefits from competition. In addition, the findings suggest that price cap regulation leads to higher rates relative to rate-of-return regulation. Chapter 2 analyzes the pricing and investment behavior of electricity firms. Electricity and natural gas markets have traditionally been serviced by one of two market structures. In some markets, electricity and natural gas are sold by a dual-product regulated monopolist, while in other markets, electricity and natural gas are sold by separate single-product regulated monopolies. This paper analyzes the relative pricing and investment decisions of electricity firms operating in the two market structures. The unique relationship between these two products imply that the relative incentives of single and dual-product firms are likely to differ. Namely electricity and natural gas are substitutes in consumption while natural

    Full Text Available In a previous behavioural study, we reported that a particular context of stimulus congruency influenced audiovisual interactions. In particular, audiovisual interaction, measured in terms of congruency effect, was reduced when a high proportion of incongruent trials was presented. We argued that this modulation was due to changes in participants' control set as a function of the context of congruency, with greater control applied when most of the trials were incongruent. Since behavioural data do not allow to specify the level at which control was affecting audiovisual interaction, we conducted an event-related potentials (ERPs study to further investigate each context of audiovisual congruency. Participants performed an audiovisual congruency task, where the stimulus onset could be present on two different contexts mixed at random: a high proportion congruent context and a low proportion congruent context. The context manipulation was found to modulate brain ERPs related to perceptual and response selection processes, ie, the N2 and P3 components. The N2 amplitude was larger for the less common trials on both high and low congruent proportion contexts, while the P3 amplitude and latency were differentially modulated by incongruent trials on the two contexts.

    Full Text Available Purpose: Companies survive in saturated markets trying to be more productive and more efficient. In this context, it becomes critical for companies to manage the entire supply network to optimize overall performance.  Hence, the supply strategy plays an important role because it influences the way in which production and logistics network has to be configured and managed. This paper explores the benefits obtained configuring different supply strategies adapted to customer needs.Design/methodology/approach: For this purpose a case research from a Tier 2 point of view of the supply chain has been conducted. Findings and Originality/value: The case research demonstrates that a higher service level, less holding costs and increase turnovers can be obtained implementing the adequate supply strategy. Originality/value: There is a scarcity of research specifically focused on applied Supply Chain Principles within network configuration processes. Moreover, there are few empirical studies of global Tier 2 with multiple decoupling points into its supply chain network.

    Skinner, Erin I; Fernandes, Myra A

    2010-07-01

    We examined how visual context information provided during encoding, and unrelated to the target word, affected later recollection for words presented alone using a remember-know paradigm. Experiments 1A and 1B showed that participants had better overall memory-specifically, recollection-for words studied with pictures of intact faces than for words studied with pictures of scrambled or inverted faces. Experiment 2 replicated these results and showed that recollection was higher for words studied with pictures of faces than when no image accompanied the study word. In Experiment 3 participants showed equivalent memory for words studied with unique faces as for those studied with a repeatedly presented face. Results suggest that recollection benefits when visual context information high in meaningful content accompanies study words and that this benefit is not related to the uniqueness of the context. We suggest that participants use elaborative processes to integrate item and meaningful contexts into ensemble information, improving subsequent item recollection.

This record reveals a period of sustained aridity that began from AD 880, followed by increased warming from AD 1100 that lasted beyond the arrival of the Spanish in AD 1532. These increasingly warmer conditions would have allowed the Inca and their immediate predecessors the opportunity to exploit higher altitudes (post-AD 1150) by constructing agricultural terraces that employed glacial-fed irrigation, in combination with deliberate agroforestry techniques. There may be some important lessons to be learnt today from these strategies for sustainable rural development in the Andes in the light of future climate uncertainty.

    1978-06-01

    This paper investigates the effects of energy policy on households in Sweden and provides the material necessary for evaluation of current and proposed energy-conservation measures. Emphasis is placed on the impact of enery taxation or price changes on household demand for electricity, heating oil, and gasoline and the consequences of such measures for income distribution. The results of the Swedish studies of household demand for heating oil and gasoline indicate that price changes can have a considerable long run impact on fuel utilization. In the short run, price responsiveness is notably reduced, but it is nevertheless of consequence for energy demand.

    Full Text Available The present study aims to analyze the accounting professionals’ point of view as opposed to the students and master students’ one, regarding the creative accounting phenomenon existence and manifestation forms. In order to accomplish this objective, there has been used the poll/investigation, as a research method and the questionnaire, as a research instrument. Within the study, there is suggested the testing of more hypotheses that contribute to the clarifying of the aspects wished to be analyzed through the research. These hypotheses’ acceptance or rejection is based on the „chi-square“ (Karl Pearson statistical test and rank ordering method. Trying to elaborate a global conclusion of the questionnaire, there could be noticed the fact that over 50% from the questioned accounting students are not tempted to use the creative accounting practices and techniques in order to optimize the taxation without breaking the actual law regulations. At the opposite side, more than a half from the questioned accounting professionals would use these practices without breaking the law regulations that lead to the taxation’s optimization. The creative accounting has a negative connotation if the accurate image of the financial position and of the performance is not targeted because it represents the essential factor for elaborating and grounding the accounting policies. However, the positive side of the creative accounting is not excluded, given that one appeals to the „fair“ professional judgment of the accounting professionals and to the good faith of managers.

  13. Guidelines for using empirical studies in software engineering education

    Directory of Open Access Journals (Sweden)

    Fabian Fagerholm

    2017-09-01

    Full Text Available Software engineering education is under constant pressure to provide students with industry-relevant knowledge and skills. Educators must address issues beyond exercises and theories that can be directly rehearsed in small settings. Industry training has similar requirements of relevance as companies seek to keep their workforce up to date with technological advances. Real-life software development often deals with large, software-intensive systems and is influenced by the complex effects of teamwork and distributed software development, which are hard to demonstrate in an educational environment. A way to experience such effects and to increase the relevance of software engineering education is to apply empirical studies in teaching. In this paper, we show how different types of empirical studies can be used for educational purposes in software engineering. We give examples illustrating how to utilize empirical studies, discuss challenges, and derive an initial guideline that supports teachers to include empirical studies in software engineering courses. Furthermore, we give examples that show how empirical studies contribute to high-quality learning outcomes, to student motivation, and to the awareness of the advantages of applying software engineering principles. Having awareness, experience, and understanding of the actions required, students are more likely to apply such principles under real-life constraints in their working life.

    Recently, researchers have reported many models mimicking real network evolution growth, among which some are based on network aggregation growth. However, until now, relatively few experiments have been reported. Accordingly, in this paper, photomicrographs of real materials (the agglomeration in the filtrate of slurry formed by a GaP-nanoparticle conglomerate dispersed in water) are analyzed within the framework of complex network theory. By data mapping from photomicrographs we generate undirected networks and as a definition of degree we adopt the number of pixel's nearest neighbors while adjacent pixels define a connection or an edge. We study the topological structure of these networks including degree distribution, clustering coefficient and average path length. In addition, we discuss the self-similarity and synchronizability of the networks. We find that the synchronizability of high-concentration agglomeration is better than that of low-concentration agglomeration; we also find that agglomeration networks possess good self-similar features

    The social amplification of risk is a theoretical framework that addresses an important deficiency of formal risk assessment methods and procedures. Typically assessments of risk from technological mishaps have been based upon the expected number of people who could be killed or injured or the amount of property that might be damaged. The diverse and consequential impacts that followed in the aftermath of the Three Mile Island accident make it clear that risk assessments that exclude the role of public perceptions of risk will greatly underestimate the potential costs of certain types of hazards. The accident at Three Mile Island produced no direct fatalities and few, if any, expected deaths due to cancer, yet few other accidents in history have had such costly societal impacts. The experience of amplified impacts argues for the development of a broadened theoretical and methodological perspective capable of integrating technical assessment of risk with public perceptions. This report presents the results to date in an ongoing research effort to better understand the complex processes by which adverse events produce impacts. In particular this research attempts to construct a framework that can account for those events that have produced, or are capable of producing, greater societal impacts than would be forecast by traditional risk assessment methods. This study demonstrates that the social amplification of risk involves interactions between sophisticated technological hazards, public and private institutions, and subtle individual and public perceptions and behaviors. These factors, and the variables underlying the intricate processes of social amplification that occur in modern society, are not fully defined and clarified in this report. 19 refs., 9 figs., 10 tabs

    We have done an empirical investigation on automobile market in Taiwan including the development of the possession rate of the companies in the market from 1979 to 2003, the development of the largest possession rate, and so on. A dynamic model for describing the competition between the companies is suggested based on the empirical study. In the model each company is given a long-term competition factor (such as technology, capital and scale) and a short-term competition factor (such as management, service and advertisement). Then the companies play games in order to obtain more possession rate in the market under certain rules. Numerical simulation based on the model display a competition developing process, which qualitatively and quantitatively agree with our empirical investigation results.

  5. Invited commentary: boundless science--putting natural direct and indirect effects in a clearer empirical context.

    Science.gov (United States)

    Naimi, Ashley I

    2015-07-15

    Epidemiologists are increasingly using natural effects for applied mediation analyses, yet 1 key identifying assumption is unintuitive and subject to some controversy. In this issue of the Journal, Jiang and VanderWeele (Am J Epidemiol. 2015;182(2):105-108) formalize the conditions under which the difference method can be used to estimate natural indirect effects. In this commentary, I discuss implications of the controversial "cross-worlds" independence assumption needed to identify natural effects. I argue that with a binary mediator, a simple modification of the authors' approach will provide bounds for natural direct and indirect effect estimates that better reflect the capacity of the available data to support empirical statements on the presence of mediated effects. I discuss complications encountered when odds ratios are used to decompose effects, as well as the implications of incorrectly assuming the absence of exposure-induced mediator-outcome confounders. I note that the former problem can be entirely resolved using collapsible measures of effect, such as risk ratios. In the Appendix, I use previous derivations for natural direct effect bounds on the risk difference scale to provide bounds on the odds ratio scale that accommodate 1) uncertainty due to the cross-world independence assumption and 2) uncertainty due to the cross-world independence assumption and the presence of exposure-induced mediator-outcome confounders. © The Author 2015.

  17. Ergonomics, quality and continuous improvement--conceptual and empirical relationships in an industrial context.

    Eklund, J

    1997-10-01

    This paper reviews the literature comparing the fields of ergonomics and quality, mainly in an industrial context, including mutual influences, similarities and differences. Relationships between ergonomics and the factors: work conditions, product design, ISO 9000, continuous improvements and TQM are reviewed in relation to the consequence, application, and process domains. The definitions of ergonomics and quality overlap substantially. Quality deficiencies, human errors and ergonomics problems often have the same cause, which in many cases can be traced to the design of work, workplace and environment e.g. noise, light, postures, loads, pace and work content. In addition, the possibility of performing to a high standard at work is an important prerequisite for satisfaction and well-being. Contradictions between the two fields have been identified in the view of concepts such as standardization, reduction of variability and copying of best practice, requiring further research. The field of quality would gain by incorporating ergonomics knowledge, especially in the areas of work design and human capability, since these factors are decisive for human performance and also therefore the performance of the systems involved. The field of ergonomics, on the other hand, would benefit from developing a stronger emphasis on methodologies and structures for improvement processes, including a clearer link with leadership and company strategies. Just as important is a further development of practicable participative ergonomics methods and tools for use at workplaces by the workers themselves, in order to integrate the top-down and the bottom-up processes and achieve better impact. Using participative processes for problem-solving and continuous improvement, focusing ergonomics and quality jointly has a great potential for improving working conditions and quality results simultaneously, and satisfying most of the interested parties.

    2017-05-01

    We investigate adjacency matrices of bipartite graphs with a power-law degree distribution. Motivation for this study is twofold: first, vibrational states in granular matter and jammed sphere packings; second, graphs encoding social interaction, especially electronic commerce. We establish the position of the mobility edge and show that it strongly depends on the power in the degree distribution and on the ratio of the sizes of the two parts of the bipartite graph. At the jamming threshold, where the two parts have the same size, localization vanishes. We found that the multifractal spectrum is nontrivial in the delocalized phase, but still near the mobility edge. We also study an empirical bipartite graph, namely, the Amazon reviewer-item network. We found that in this specific graph the mobility edge disappears, and we draw a conclusion from this fact regarding earlier empirical studies of the Amazon network.

    2012-06-01

    Full Text Available The personal computers era made advanced programming tasks available to end users. Spreadsheet models are one of the most widely used applications that can produce valuable results with minimal training and effort. However, errors contained in most spreadsheets may be catastrophic and difficult to detect. This study attempts to investigate the influence of experience and spreadsheet presentation on the error finding performance by end users. To reach the target of the study, 216 business and finance students participated in a task of finding errors in a simple free cash flow model. The findings of the study reveal that presentation of the spreadsheet is of major importance as far as the error finding performance is concerned, while experience does not seem to affect students on their performance. Further research proposals and limitations of the study are, moreover, discussed.

    We present the study of a wreck, in a foreshore area, in the North of Brittany, France, using two different digitization methods, photogrammetry and laser scanning. The digitization process had to deal with the tide constraints. The 3D data produced using these technologies has been deployed in a large immersive infrastructure dedicated to virtual reality research, in order to propose new practises for archaeologists. The overall purpose of our research project is to define an innovative and efficient methodology for the study and preservation of cultural heritage in an inter-tidal context. In the inter-tidal context, heritage is really fragile and the risk of destruction is real (storms, erosion, coastal development...). The traditional methods are no longer efficient. This paper describes preliminary results, through the joint work of a research institute specialized in underwater archaeology, a research laboratory of archaeology and archaeosciences, and a research laboratory in computer science.

    2015-02-01

    Full Text Available Wen and Wang (2004 reviewed the empirical studies over the past two decades (from 1984 to 2003 on learning strategies that Chinese EFL learners used. This article, following their methodological framework, reviews about 45 empirical studies on Chinese EFL learners’ English vocabulary learning strategies, conducted by Mainland Chinese scholars over the past two decades. The review shows that more than half of the Chinese scholars are interested in questionnaire investigation of EFL learners’ preferences for vocabulary learning. The reports of the questionnaire investigations indicate that most Chinese EFL learners prefer rote learning of vocabulary to learning vocabulary in context or through language use. The experimental studies suggest that strategies-based instruction results in the learners’ vocabulary achievement. Cognitive and metacognitive strategies are the two groups of strategies that Chinese researchers show particular interest in.

    2013-10-16

    We test whether traditional ecological knowledge (TEK) about how to make an item predicts a person's skill at making it among the Tsimane' (Bolivia). The rationale for this research is that the failure to distinguish between knowledge and skill might account for some of the conflicting results about the relationships between TEK, human health, and economic development. We test the association between a commonly-used measure of individual knowledge (cultural consensus analysis) about how to make an arrow or a bag and a measure of individual skill at making these items, using ordinary least-squares regression. The study consists of 43 participants from 3 villages. We find no association between our measures of knowledge and skill (core model, p > 0.5, R2 = .132). While we cannot rule out the possibility of a real association between these phenomena, we interpret our findings as support for the claim that researchers should distinguish between methods to measure knowledge and skill when studying trends in TEK.

    2017-01-01

    Hospitals vary from one another in terms of their specialty, services offered, and resource availability. Their services are widely measured with scales that gauge patients' perspective. Therefore, there is a need for research to develop a scale that measures hospital service quality in Asian hospitals, regardless of their nature or ownership. To address this research need, this study adapted the SERVQUAL instrument to develop a service quality measurement scale. Data were collected from inpatients and outpatients at 9 different hospitals, and the scale was developed using structural equation modeling. The developed scale was then validated by identifying service quality gaps and ranking the areas that require managerial effort. The findings indicated that all 5 dimensions of SERVQUAL are valid in Asian countries such as Pakistan, with 13 items retained. Reliability, tangibility, responsiveness, empathy, and assurance were ranked first, second, third, fourth, and fifth, respectively, in terms of the size of the quality gap. The gaps were statistically significant, with values ≤.05; therefore, hospital administrators must focus on each of these areas. By focusing on the identified areas of improvement, health care authorities, managers, practitioners, and decision makers can bring substantial change within hospitals.

    The empirical studies team of MCC's Design Process Group conducted three studies in 1986-87 in order to gather data on professionals designing software systems in a range of situations. The first study (the Lift Experiment) used thinking aloud protocols in a controlled laboratory setting to study the cognitive processes of individual designers. The second study (the Object Server Project) involved the observation, videotaping, and data collection of a design team of a medium-sized development project over several months in order to study team dynamics. The third study (the Field Study) involved interviews with the personnel from 19 large development projects in the MCC shareholders in order to study how the process of design is affected by organizationl and project behavior. The focus of this report will be on key observations of design process (at several levels) and their implications for the design of environments.

    2017-01-01

    Full Text Available There is no doubt that strategic management tools and techniques are important parts of the strategic management process. Their use in organizations should be observed in a practice-based context. This paper analyzes the empirical studies on the usage of strategic management tools and techniques. Hence, the main aim of this study is to investigate and analyze which enterprises, according to their country development level, use more strategic management tools and techniques and which of these are used the most. Also, this paper investigates which strategic management tools and techniques are used globally according to the results of empirical studies. The study presents a summary of empirical studies for the period 1990–2015. The research results indicate that more strategic tools and techniques are used in developed countries, followed by developing countries and fewest in countries in transition. This study is likely to contribute to the field of strategic management because it summarizes the most used strategic tools and techniques at the global level according to varying stages of countries’ economic development. Also, the findings from this study may be utilized to maximize the full potential of enterprises and reduce the cases of entrepreneurship failures, through creating awareness of the importance of using strategic management tools and techniques.

    Koch, Stefan; Mitteregger, Kurt

    2016-01-01

    The amount of customisation to an enterprise resource planning (ERP) system has always been a major concern in the context of the implementation. This article focuses on the phase of maintenance and presents an empirical study about the relationship between the amount of customising and the resulting support effort. We establish a structural equation modelling model that explains support effort using customisation effort, organisational characteristics and scope of implementation. The findings using data from an ERP provider show that there is a statistically significant effect: with an increasing amount of customisation, the quantity of telephone calls to support increases, as well as the duration of each call.

    Full Text Available Economic development is one of the primary objectives of any government. Fiscal policy represents one of the most effective tools that government authorities could use in order to influence the economy. Having this in mind, this paper focuses on the connection between economic development and fiscal policy and proposes an empirical study based on a sample of 21 European countries. Using a simple pool data model, we tried to distinguish the relations between the evolution of GDP per capita, as a proxy for economic development, and the evolution of three fiscal policy variables, namely the tax burden, the public expenditure to GDP ratio and the budget deficit to GDP ratio.

    Full Text Available For many years, a trend for businesses has been to increase market segmentation and extend product and service-variety offerings in order to provid more choice for customers and gain a competitive advantags. However, there have been relatively few variety-related, empirical studies that have been undertaken. In this research, two empirical studies are presented that address the impact of product and service variety on business and business function performance. In the first (service-variety study, the focus concerns the relationship between service provision offered by UK-based, third-party logistics (3PL providers and the operational and financial performance of those providers. Here, the results of a large survey identify the  most important services offered by 3PLs and the most important aspects of 3PL operational performance. Also, the research suggests that the range of service variety offered by 3PLs does not directly influence the 3PLs’ financial performance. The second (product-variety study presents the findings from an analysis of data from 163 manufacturing plants where the impact of product variety on the performance of five business functions is examined. An increase in product variety was found to influence business functions differently depending on the combination of customisation and variety offered to customers

    Full Text Available To model and analyse stroke care and assistance provision in the Portuguese context from the network perspective. We used the network theory as a theoretical foundation for the study. The model proposed by Frey et al. (2006 was used to elicit and comprehend possible interactions and relations between organisations expected to be involved in the provision of care and assistance to stroke patients in their pathway to rehabilitation. Providers were identified and contacted to evaluate the nature and intensity of relationships. Network analysis was performed with the NodeXL software package. Analysis of 509 entities based on about 260 000 entries indicates that stroke care provision in the evaluated context is best captured in the coalition-collaboration setting, which appears to best demonstrate the character of the network. Information from analysis of the collaboration stage was not sufficient to determine the network dynamics. Application of the network theory to understand interorganisational dynamics of the complex health care context. Empirical validation of the model proposed by Frey et al. (2006 in terms of its operationalisation and the way it actually reflects the practical context. Examination and analysis of interorganisational relationships and its contribution to management of compound health care context involving actors from various sectors.

    2012-01-01

    In X-ray fluorescence, the earlier derived matrix effects from fundamental relations of intensities of analyte/matrix elements with basic atomic and experimental setup parameters and tested on synthetic known samples were found empirically related to analyte/matrix elemental amounts. The present study involves the application of these relations on potassium and calcium macronutrients of maize saplings treated with different fertilizers. The novelty of work involves a determination of an element in the presence of its secondary excitation rather than avoiding the secondary fluorescence. Therefore, the possible utility of this process is in studying the absorption for some intermediate samples in a lot of a category of samples with close Z interfering constituents (just like Ca and K). Once the absorption and enhancement terms are fitted to elemental amounts and fitted coefficients are determined, with the absorption terms from the fit and an enhancer element amount known from its selective excitation, the next iterative elemental amount can be directly evaluated from the relations. - Highlights: ► Empirical formulation for matrix corrections in terms of amounts of analyte and matrix element. ► The study applied on K and Ca nutrients of maize, rice and potato organic materials. ► The formulation provides matrix terms from amounts of analyte/matrix elements and vice versa.

    Phenomenological psychopathology, through theoretical and idiographic studies, conceptualizes major depressive disorder (MDD) as a disorder of time experience. Investigations on abnormal time experience (ATE) in MDD adopting methodologies requested by the standards of empirical sciences are still lacking. Our study aimed to provide a qualitative analysis, on an empirical ground and on a large scale, of narratives of temporal experiences of persons affected by MDD. We interviewed 550 consecutive patients affected by affective and schizophrenic disorders. Clinical files were analysed by means of consensual qualitative research. Out of 100 MDD patients, 96 reported at least 1 ATE. The principal categories of ATE are vital retardation - the experience of a stagnation of endogenous vital processes (37 patients), the experience of present and future dominated by the past (29 patients), and the experience of the slackening of the flow oftime (25 patients). A comparison with ATE in schizophrenia patients showed that in MDD, unlike in schizophrenia, there is no disarticulation of time experience (disorder of temporal synthesis) but rather a disorder of conation or inhibition of becoming. The interview style was not meant to make a quantitative assessment ("false negatives" cannot be excluded). Our findings confirm the relevance of distinctive features of ATE in MDD, support the hypothesis of an intrinsic disordered temporal structure in depressive symptoms, and may have direct implications in clinical practice, especially in relation to differential diagnosis, setting the boundaries between "true" and milder forms of depression, and neurobiological research. © 2016 S.

    Full Text Available The article presents the situation of youth in contemporary society. Neoliberal economy, ageing society, rapid globalisation, technological changes, increase of social risk have prompted specific, historically unfamiliar, and fairly difficult to forecast social change. Social adaptation and construction of own identity are becoming challenging to youth as a specific social group in this period of great uncertainty, risk, and opportunities. Youth studies are referred to as one of the means to help understand the youth phenomenon and form the respective policy. Aim of the article is to reveal the role of youth studies as a specific interdisciplinary genre of the empirical-analytic paradigm in social sciences. Research objectives: (1 To identify the traditions of youth studies and differences between them; (2. To reveal the specific character of youth studies as an empirical paradigm in the contemporary context. Analysis of scientific sources and document analysis are used for achievement of the goal and objectives. Since the 20th century, youth studies have been developing as an independent research discipline and tradition. Perception of the notion of a young person has been changing along with development of the paradigmatic and methodological research traditions. Modernity has doubtlessly contributed to a young person finding his/her place in other age groups and putting an emphasis on the importance of youth as a specific social group. Recently, youth has been viewed as both the risk and the opportunity group. Although qualitative research, in particular, where youth emancipation is aspired, prevails in the contemporary research tradition, the empirical-analytic paradigm has not lost its relevance. The research has demonstrated that empirical-analytic paradigm is a specific genre of the youth studies characterised by quantitative approach and strong link to politics and practical situation of the phenomenon.

    Full Text Available The importance of diversification and performance in then strategic management literature is widely accepted among academics and practitioners . However, the proxies for performance and diversification that have been employed in past strategy research has not been unanimously agreed upon. Given the current state of confusion that exists with regard to the impact of corporate diversification on firm performance in selected Nigerian companies. The reason for increased interest in diversification has always been on the possibility that diversification is related to corporate performance. However , while this topic is rich in studies, empirical evidence semerging from various studies about the effect of diversification on performance have so far yield mixed results that are inconclusive and contradictory. In addition , despite the existence of these studies, very litlle attention has been given to the companies in developing countries including Nigeria. This means that there is a major gap in the relevant literature on developing countries which has to be covered by research. This research attempts to fill this gap by studying the situation of the Nigeria companies and providing more empirical evidence on the effects of corporate diversification on firm performance based on individual company-level data. Survey research design was adopted in this study with the application of simple random sampling tehnique in selecting our case study companies as well as our respondents. Primary data were collected through questionnaire. Data were analysed through descriptive statistics and correlation and coefficient of determination were used to test our hypothese. It was discovered that diversification impacted performance of these companies posivitely and we recommend that these companies should engage in geographical diversification in addition to other forms of diversification they are currently involved in for maximum performance.

    Full Text Available Empowering workers play an essential role on increasing productivity in any organization. The service industries such as insurance companies or banks mostly rely on their own people to retain their customers and incomes. The recent increasing trend on the number of private banks in Iran has increased competition among existing banks. The banking industry strives to empower its employees as much as possible in an attempt to maintain market share by not losing its customers. In this paper, we present an empirical study to detect the most important factors empowering bank employees. The study is implemented for a recently established private bank with 228 people with 32 questions where 15 questions are focused on empowering employees. The results are analyzed using statistical tests and descriptive methods. The results indicate that leadership, academic qualification, appropriate policy and strategy, cooperation and processes play important role on empowering and enabling bank's employee.

    2016-06-01

    Full Text Available This article describes the methodology and the outcomes of an empirical study of conflict narratives. The narratological analysis deployed narratological catego­ries in the structuralist tradition based on Genette and was conducted with the help of the text annotation tool CATMA. The analysis aimed at covering as many narratological phenomena as possible by establishing 14 fields of narrato­logical phenomena that were annotated in a corpus of 39 factual narratives about situations at the workplace with and without conflicts. The evaluation of approximately 28,000 annotations brought to light a series of interrelations be­tween narratological phenomena and the presence or absence of conflicts in the narratives. Additionally, this approach led to the identification of some over­sights of narrative theory by detecting hitherto unnoticed interrelations among narratological concepts.

    2017-06-01

    Pedestrian crowds often include social groups, i.e. pedestrians that walk together because of social relationships. They show characteristic configurations and influence the dynamics of the entire crowd. In order to investigate the impact of social groups on evacuations we performed an empirical study with pupils. Several evacuation runs with groups of different sizes and different interactions were performed. New group parameters are introduced which allow to describe the dynamics of the groups and the configuration of the group members quantitatively. The analysis shows a possible decrease of evacuation times for large groups due to self-ordering effects. Social groups can be approximated as ellipses that orientate along their direction of motion. Furthermore, explicitly cooperative behaviour among group members leads to a stronger aggregation of group members and an intermittent way of evacuation.

    Full Text Available The study analyses managers’ behaviour from Romania when dealing with creative accounting. For this we realized an empirical study within the Arad county space, having as main objective the identification of the managers’ perception regarding the usefulness of accounting information and of other factors considered when making decisions. Another aspect was to interpret the managers’ tendency towards manipulation or strategic management of results. The empirical research was carried out between December 2013 and January 2014, and the research method used was the survey, and as an instrument of the research we used the questionnaire. The questionnaires were posted on a website but some of them were applied directly in the field to ensure a response rate of at least 30%. For the analysis and confirmation of the feasibility of the questionnaire and of the measurement scale, we used Cronbach Alpha method. The results obtained after statistically processing the answers received from respondents and after testing the research hypotheses show that there is an increased interest of the managers from the investigated Arad firms to improve the quality of the financial accounting information and to give the users as beautiful an image as possible of the company’s performances; it is noticed their inclination to the manipulation of the accounting figures. On the other hand the results obtained demonstrate that, despite the fact that most of the managers from the sample consider that using ethics is a priority in making decisions, this idea is not an obstacle for more than a half to change an accounting policy that would affect the true image but would be favorable to the image of the company The utility of such research contributes to the insurance of the premises for the development of future research, looking to test the reaction of the professional accountants in our country, regarding the phenomenon of creative accounting.

    2016-10-01

    Full Text Available As an effect of marketisation, the importance of workplace learning in Germany has increased. The article follows up on the long-standing discourse around the question of how economic and pedagogical ideals interact in this context. In order to develop a theoretical framework for empirical research, three major positions of the discipline of business ethics are introduced. Business ethics in more abstract ways deals with the very same question, namely how do ideas such as profit orientation interact with other norms and values? The new perspectives show that the discourse has been hitherto based on a specific understanding of economy. In order to derive an empirical answer to the research question, the question is re-formulated as follows: Which values are inherent in the decisions taken? Consequently, it suggests using the concept of "rationalities of justification" for empirical research. The article shows how this concept can be applied by conducting a test run.

    Full Text Available Purpose: This empirical study aims to determine the effects of a toxic workplace environment, which can negatively impact the job productivity of an employee. Methodology: Three hundred questionnaires were randomly distributed among the staff members of seven private universities in Pakistan with a final response rate of 89%. For analysis purposes, AMOS 22 was used to study the direct and indirect effects of the toxic workplace environment on job productivity. Confirmatory Factor Analysis (CFA was conducted to ensure the convergent and discriminant validity of the factors, while the Hayes mediation approach was used to verify the mediating role of job burnout between the four dimensions of toxic workplace environment and job productivity. A toxic workplace with multiple dimensions, such as workplace ostracism, workplace incivility, workplace harassment, and workplace bullying, was used in this study. Findings: By using the multiple statistical tools and techniques, it has been proven that ostracism, incivility, harassment, and bullying have direct negative significant effects on job productivity, while job burnout was shown to be a statistical significant mediator between the dimensions of a toxic workplace environment and job productivity. Finally, we concluded that organizations need to eradicate the factors of toxic workplace environments to ensure their prosperity and success. Practical Implications: This study encourages managers, leaders, and top management to adopt appropriate policies for enhancing employees’ productivity. Limitations: This study was conducted by using a cross-sectional research design. Future research aims to expand the study by using a longitudinal research design.

    Full Text Available No studies have been conducted to link three variables of work values, internal marketing, and job satisfaction in predicting employee loyalty. Therefore, this research aims to fulfill the gap by developing a model that include work values, internal marketing, and job satisfaction in assessing employee loyalty in educational context. This research applies a judgmental sampling with the sample size of 200 lecturers from private universities in Tangerang. Structural equation modeling was applied in testing the research hypotheses. The results showed that there is one out of three hypotheses that were not supported. That hypothesis is the relationship between internal marketing and job satisfaction.

  1. Data envelopment analysis in service quality evaluation: an empirical study

    Science.gov (United States)

    Najafi, Seyedvahid; Saati, Saber; Tavana, Madjid

    2015-09-01

    Service quality is often conceptualized as the comparison between service expectations and the actual performance perceptions. It enhances customer satisfaction, decreases customer defection, and promotes customer loyalty. Substantial literature has examined the concept of service quality, its dimensions, and measurement methods. We introduce the perceived service quality index (PSQI) as a single measure for evaluating the multiple-item service quality construct based on the SERVQUAL model. A slack-based measure (SBM) of efficiency with constant inputs is used to calculate the PSQI. In addition, a non-linear programming model based on the SBM is proposed to delineate an improvement guideline and improve service quality. An empirical study is conducted to assess the applicability of the method proposed in this study. A large number of studies have used DEA as a benchmarking tool to measure service quality. These models do not propose a coherent performance evaluation construct and consequently fail to deliver improvement guidelines for improving service quality. The DEA models proposed in this study are designed to evaluate and improve service quality within a comprehensive framework and without any dependency on external data.

    Full Text Available Climatic variations affect agriculture in a process with no known end means. Adaptations help to reduce the adverse impacts of climate change. Unfortunately, adaptation has never been considered as a process. Current study empirically identified the adaptation process and its different stages. Moreover, little is known about the farm level adaptation strategies and their determinants. The study in hand found farm level adaptation strategies and determinants of these strategies. The study identified three stages of adaptation i.e. perception, intention and adaptation. It was found that 71.4% farmers perceived about climate change, 58.5% intended to adapt while 40.2% actually adapted. The study further explored that farmers do adaptations through changing crop variety (56.3%, changing planting dates (44.6%, tree plantation (37.5%, increase/conserve irrigation (39.3% and crop diversification (49.2%. The adaptation strategies used by farmers were autonomous and mostly determined perception to climate change. It was also noted that the adaptation strategies move in a circular process and once they are adapted they remained adapted for a longer period of time. Some constraints slow the adaptation process so; we recommend farmers should be given price incentives to speed-up this process.

    Full Text Available Purpose: In a multitude of studies, it is verified that the generation of positive attitudes for employees such as job satisfaction or job involvement, have a positive influence on productivity levels of companies. The current investigation focus on the identification of employee-profile -who is emotionally involved with their work activity- through the use of a set of individual, job related and attitudinal factors.Design/methodology: A review of the literature about the main factors that affect the job involvement particularly on its emotional dimension has been completed. For its measurement at the empirical level, various items related to psychological well being of employees included in the IV European Working Conditions Survey-2010 are used. Moreover, those items are identified in Job Involvement Questionnaire (Lodahl & Kejner, 1965. Since then, an empirical and multidimensional study is carried out by applying a logistic regression model on the sample of 11,149 employees obtained with European survey cited previously.Findings: The logistic regression model identifies the factors, which are directly related to emotional involvement at the workplace. Ultimately, is raised a definitive model that define the European employee-profile -who is emotionally involved at the workplace-: a rather aged person who has been working at his/her present place of employment for several years in a medium-sized company where possibly there exist a good working relationship between workers and their superiors –social support-. These employees are “white-collar” workers, have career advancement opportunities in the organizational hierarchy. They perform variety, flexible and complex tasks, which leads to satisfaction in terms of pay and working conditions.Research limitations/implications: Emotional involvement has been measured through self-awareness and, therefore, the corresponding bias in the key variable must be assumed. In addition, the casual

    In written and spoken communications, figures of speech (e.g., metaphors and synecdoche) are often used as an aid to help convey abstract or less tangible concepts. However, the benefits of using rhetorical illustrations or embellishments in visualization have so far been inconclusive. In this work, we report an empirical study to evaluate hypotheses that visual embellishments may aid memorization, visual search and concept comprehension. One major departure from related experiments in the literature is that we make use of a dual-task methodology in our experiment. This design offers an abstraction of typical situations where viewers do not have their full attention focused on visualization (e.g., in meetings and lectures). The secondary task introduces "divided attention", and makes the effects of visual embellishments more observable. In addition, it also serves as additional masking in memory-based trials. The results of this study show that visual embellishments can help participants better remember the information depicted in visualization. On the other hand, visual embellishments can have a negative impact on the speed of visual search. The results show a complex pattern as to the benefits of visual embellishments in helping participants grasp key concepts from visualization.

    Priority setting research has focused on the macro (national) and micro (bedside) level, leaving the meso (institutional, hospital) level relatively neglected. This is surprising given the key role that hospitals play in the delivery of healthcare services and the large proportion of health systems resources that they absorb. To explore the factors that impact upon priority setting at the hospital level, we conducted a thematic review of empirical studies. A systematic search of PubMed, EBSCOHOST, Econlit databases and Google scholar was supplemented by a search of key websites and a manual search of relevant papers' reference lists. A total of 24 papers were identified from developed and developing countries. We applied a policy analysis framework to examine and synthesize the findings of the selected papers. Findings suggest that priority setting practice in hospitals was influenced by (1) contextual factors such as decision space, resource availability, financing arrangements, availability and use of information, organizational culture and leadership, (2) priority setting processes that depend on the type of priority setting activity, (3) content factors such as priority setting criteria and (4) actors, their interests and power relations. We observe that there is need for studies to examine these issues and the interplay between them in greater depth and propose a conceptual framework that might be useful in examining priority setting practices in hospitals.

    The Health Risk Reminders and Surveillance (HRRS) system was designed to deliver critical abnormal test results of severely ill patients from Laboratory, Radiology, and Pathology departments to physicians within 5 min using cell phone text messages. This paper explores the success of the HRRS system. This study employed an augmented version of the DeLone and McLean IS success model. Seven variables (system quality, information quality, system use, user satisfaction, mobile healthcare anxiety, impact on the individual and impact on the organization) were used to evaluate the success of the HRRS system. The interrelationships between the seven variables were hypothesized and the hypotheses were empirically tested. The results indicate that the information quality of the HRRS system is positively associated with both system use and user satisfaction. In addition, system use is positively associated with user satisfaction, which is also positively associated with mobile healthcare anxiety. Moreover, results indicate that impact on the individual is positively associated with both user satisfaction and mobile healthcare anxiety. Finally, the impact of the organization is positively associated with impact on the individual. The results of the study provide an expanded understanding of the factors that contribute to mobile patient safety information system (IS) success. Implications of the relationship between system use and physician mobile healthcare anxiety are discussed.

    Many safety-critical aircraft functions are software-enabled. Airborne software must be audited and approved by the aerospace certification authorities prior to deployment. The auditing process is time-consuming, and its outcome is unpredictable, due to the criticality and complex nature of airborne software. To ensure that the engineering of airborne software is systematically regulated and is auditable, certification authorities mandate compliance with safety standards that detail industrial best practice. This paper reviews existing practices in software safety certification. It also explores how software safety audits are performed in the civil aerospace domain. The paper then proposes a statistical method for supporting software safety audits by collecting and analysing data about the software throughout its lifecycle. This method is then empirically evaluated through an industrial case study based on data collected from 9 aerospace projects covering 58 software releases. The results of this case study show that our proposed method can help the certification authorities and the software and safety engineers to gain confidence in the certification readiness of airborne software and predict the likely outcome of the audits. The results also highlight some confidentiality issues concerning the management and retention of sensitive data generated from safety-critical projects.

    Full Text Available A low-carbon economy is an inevitable choice for achieving economic and ecological sustainable development. It is of significant importance to analyze a city’s low-carbon economy development level scientifically and reasonably. In order to achieve this goal, we propose an urban low-carbon economic development level evaluation model based on the matter-element extension method. First, we select some indicators from the existing indicator system based on past research and experience. Then, a matter-element model is established on the basis of weight to evaluate the level of a city’s low-carbon, the critical value of each index is determined through the classical domain and the section domain, calculating the correlation degree of a single index and a comprehensive index. Finally, we analyze the low-carbon economy development status and future development trends according to the analysis results. In this study, we select Shanghai as an empirical study—the results show that Shanghai is a city with a low-carbon level and there is a trend of further improvement in Shanghai’s low-carbon economy. But its low carbon construction and low carbon technology investment are relatively low. In summary, this method can provide another angle for evaluating a city’s low-carbon economy.

    The Next Generation Science Standards (NGSS) advocated by the National Research Council emphasize the connections among Science, Technology, Engineering, and Mathematics (STEM) disciplines. By design, NGSS is expected to replace the previous science education standards to enhance the quality of STEM education across the nation. To support this initiative, this investigation was conducted to fill a void in the research literature by developing an empirical indicator for the relationship of student performance across STEM subjects using a large-scale database from the Trends in Mathematics and Science Study (TIMSS). In particular, an innovative approach has been taken in this study to support the canonical correlation analysis of student plausible scores between physics and other STEM subjects at different grade levels and in a cross-country context. Results from this doctoral research revealed the need to strengthen the alignment between the intended, implemented, and attained curricula to support the integration of STEM disciplines in the United States.

    There is a constant search for ways to achieve a competitive advantage through new manufacturing techniques. Best performing manufacturing companies tend to use world-class manufacturing (WCM) practices. Although the last few years have witnessed phenomenal growth in the use of WCM techniques, their effectiveness is not well understood specifically in the context of less developed countries. This paper presents an empirical study to investigate the impact of company size on improving manufacturing performance in manufacturing organizations based in Trinidad and Tobago (T and T). Empirical data were collected via a questionnaire survey which was send to 218 manufacturing firms in T and T. Five different company sizes and seven different industry sectors were studied. The analysis of survey data was performed with the aid of Statistical Package for Social Sciences (SPSS) software. The study signified facilitating and impeding factors towards improving manufacturing performance. Their relative impact/importance is dependent on varying company size and industry sectors. Findings indicate that T and T manufacturers are still practicing traditional approaches, when compared with world class manufacturers. In the majority of organizations, these practices were not 100% implemented even though they started the implementation process more than 5 years ago. The findings provided some insights in formulating more optimal operational strategies, and later develop action plans towards more effective implementation of WCM in T and T manufacturers

    2017-04-01

    Full Text Available Orientation: A critical reading of the human resource management (HRM literature finds limited contributions to understanding the organisational determinants of social enterprises and how these may contribute to higher levels of social innovativeness. Although innovation is a key theme in organisational research it has been acknowledged that the field needs more theory-based examinations of different types of innovativeness. Research purpose: To determine how different organisational capabilities are related to social innovation. Motivation for the study: Many social enterprises in developing countries do not have the requisite capabilities to efficiently manage all their programmes, which presents a major threat to organisational sustainability. Research design, approach and method: The empirical analysis is a cross-sectional study based on primary survey data. Hypotheses are tested using correlational and regression analysis. Main findings: The results show that the organisational learning capabilities of knowledge conversion, risk management, organisational dialogue and participative decision-making all have a significant and positive relationship with social innovation. Practical/managerial implications: Managers and practitioners can leverage the different organisational learning capabilities to improve social innovations in their social enterprises. Contribution/value-add: The study is one of the first in an African market context to empirically investigate social enterprises in terms of social innovation and organisational learning perspectives.

    Imagine an agent that performs tasks according to different strategies. The goal of Behavioral Recognition (BR) is to identify which of the available strategies is the one being used by the agent, by simply observing the agent's actions and the environmental conditions during a certain period of time. The goal of Behavioral Cloning (BC) is more ambitious. In this last case, the learner must be able to build a model of the behavior of the agent. In both settings, the only assumption is that the learner has access to a training set that contains instances of observed behavioral traces for each available strategy. This paper studies a machine learning approach based on Probabilistic Finite Automata (PFAs), capable of achieving both the recognition and cloning tasks. We evaluate the performance of PFAs in the context of a simulated learning environment (in this case, a virtual Roomba vacuum cleaner robot), and compare it with a collection of other machine learning approaches.

    Full Text Available In order for the Open Access (OA to learning concept to a have wider impact in formal education, it is important that faculty members intent to adopt new educational innovations. However, little is known about which variables influence the intention of faculty members. Therefore, the purposes of this study are to empirically determine: 1 which of the characteristics of the educational innovation significantly influence the intention to adopt educational innovations, 2 which variables influence the readiness of faculty members intention to adopt educational innovations, and 3 how the characteristics of the innovations moderate the relationship between faculty readiness and intention to adopt the innovations. Participants of this study include 335 faculty members in ABET certified computer science and electrical engineering programs in the United States. The results show that ease of use is positively related to the intention of faculty members to adopt an educational innovation. We conclude that Open-CourseWare developers need to ensure that ease of use is emphasized in the CourseWare and they need to propagate these initially in institutions where faculty members have positive attitude to the CourseWare and care about student learning. In addition, a new method of identifying, building, and funding “open access grant” universities that develop easy-to-use educational innovations, make them available on an open access platform, and spread them widely by embedding agents in community colleges, schools, and other educational institutions is essential. Such an initiative may lead to wider adoption of MOOCS and other open access materials.

    We report the results of an extensive molecular-dynamics study of diffusion in liquid Si and Ge (l-Si and l-Ge) and of impurities in l-Ge, using empirical Stillinger-Weber (SW) potentials with several choices of parameters. We use a numerical algorithm in which the three-body part of the SW potential is decomposed into products of two-body potentials, thereby permitting the study of large systems. One choice of SW parameters agrees very well with the observed l-Ge structure factors. The diffusion coefficients D(T) at melting are found to be approximately 6.4×10-5 cm2/s for l-Si, in good agreement with previous calculations, and about 4.2×10-5 and 4.6×10-5 cm2/s for two models of l-Ge. In all cases, D(T) can be fitted to an activated temperature dependence, with activation energies Ed of about 0.42 eV for l-Si, and 0.32 or 0.26 eV for two models of l-Ge, as calculated from either the Einstein relation or from a Green-Kubo-type integration of the velocity autocorrelation function. D(T) for Si impurities in l-Ge is found to be very similar to the self-diffusion coefficient of l-Ge. We briefly discuss possible reasons why the SW potentials give D(T)'s substantially lower than ab initio predictions.

    Paaso, Ilkka

    Contingency theory and management control systems research offer avenues for investigating how contextual factors in organizations affect performance. This quantitative case study investigates how the context of CERN internal services influences the performance consciousness of functional service managers. A literature review recognized four contingency factors relevant for performance consciousness: interdependence, scope, standardization and variation. Data from these factors was measured empirically using a cross-sectional electronic survey and supplemented by data gathered from CERN internal documentation. A quantitative analysis of the data was performed using structural equation modelling. The main findings were congruent with existing literature indicating that a.) high interdependence between work units is associated with decreased variation, increased standardization and increased performance consciousness. b.) high scope is related to increased variation and decreased standardization. Overall, a bet...

    It has been questioned by researchers in robotics as well in the general public to what extent companion-type robots can support the elderly with the fulfillment of their psychological and social needs. Although these robots have already been used in care settings in Germany, research has referred little to this practical experience in order to analyze their impact and benefit. To start to close this gap, the current article reports on the current use of companion-type robots in care settings, on the effects reported by professional caregivers as well as on the role of psychosocial needs in the acceptance and use of companion-type robots by the elderly. In the first study, 30 professional caregivers with experience in the use of the robot seal Paro in care settings were interviewed regarding Paro's application and the observed effects on their clients. In the second study, three case examples are presented from an interaction study in which vulnerable elderly persons had the robot dinosaur Pleo at their disposal for a maximum period of 15 days. Paro is used very flexibly in a variety of settings and with a broad range of user groups (study 1). The reported psychosocial effects were mainly positive but short term. The case examples (study 2) show that psychosocial needs can both foster or hinder robot acceptance and use. They also emphasize the important role of caregivers in the interaction between the elderly and emotional robots in the context of eldercare. The beneficial and ethical use of companion-type robots in care settings demands a high commitment on the part of the caregivers. Given this prerequisite, emotional robots can be a valuable therapeutic tool.

    This paper presents framework of reverse logistics optimizing the stakeholders gain, social gain, economic gain and environmental gain. It identifies the roadblocks that prevail in recycling industry and describes various types of returns and wastes. Framework of the reverse logistics is evolved on the basis of actual happening of the items shown in table 1-4 disposed off from industries shown in table 6. The rejected items require environmental disposal passing through the different phases described in flow of operational framework. An operational framework of reverse logistics is developed studying fifty organizations.. In ad -dition three best practices of reverse logistics are proposed by consolidating the experiential information and rich hands on industrial experience in supply chain and reverse logistics area. The research has proposed the Social, Stakeholder, Economic and Environmental (SSEE) sustained gain model optimizing the benefits of stakeholders and highlights the variety of waste and its operational methodology in Pakistani industry. The proposed framework does not include the hospital waste, radioactive waste, hazardous materials waste, municipal waste, agricultural waste and cold chain waste like meat, milk, etc.The operational framework is existing way of doing that takes the waste materials from point of origin to the point of recycling. A better understanding of this framework may help researchers and front line managers to develop better, more ac -curate models for effective and sustainable utilization of waste materials, benefiting organizations and soci -ety by simultaneously enhancing the cost effectiveness and improving environmental awareness. The paper provides an operational framework of reverse logistics and 2S2E sustained gain model. Specific applications are examined through empirical research. (author)

    To examine the nature, scope and significance of virtues in the biographies of medical practitioners and to determine what kind of virtues are at play in their ethical behaviour and reflection. A case study involving 19 medical practitioners associated with the Sydney Medical School, using semi-structured narrative interviews. Narrative data were analysed using dialectical empiricism, constant comparison and iterative reformulation of research questions. Participants represented virtuous acts as centrally important in their moral assessments of both themselves and others. Acts appeared to be contextually virtuous, rather than expressions of stable character traits, and virtue was linked to acts that served to protect or enhance fundamental values attached to ontological security and human flourishing. Virtue ethics, in this sense, was the single most important ethical system for each of the participants. Virtue ethics, construed as the appraisal of acts in contexts of risk, danger or threat to foundational values, emerged as the 'natural' ethical approach for medical practitioners in this case study. Teaching medical ethics to students and graduates alike needs to accommodate the priority attached to virtuous acts. © 2011 Blackwell Publishing Ltd.

    2012-08-01

    The classification of building facade images is a challenging problem that receives a great deal of attention in the photogrammetry community. Image classification is critically dependent on the features. In this paper, we perform an empirical feature evaluation task for building facade images. Feature sets we choose are basic features, color features, histogram features, Peucker features, texture features, and SIFT features. We present an approach for region-wise labeling using an efficient randomized decision forest classifier and local features. We conduct our experiments with building facade image classification on the eTRIMS dataset, where our focus is the object classes building, car, door, pavement, road, sky, vegetation, and window.

Three hypotheses are tested using a sample of 164 large Spanish firms. The results show that organizational complexity and centralization exert a positive and a negative influence, respectively, on knowledge performance, which confirms the two hypotheses related to these variables. However, the analysis reveals no empirical evidence to confirm the hypothesis that formalization and knowledge performance are related positively.

    Directory of Open Access Journals (Sweden)

    J. De Keyser

    2005-06-01

    Full Text Available The magnetospheric boundary is always moving, making it difficult to establish its structure. This paper presents a novel method for tracking the motion of the boundary, based on in-situ observations of the plasma velocity and of one or more additional observables. This method allows the moving boundary to be followed for extended periods of time (up to several hours and aptly deals with limitations on the time resolution of the data, with measurement errors, and with occasional data gaps; it can exploit data from any number of spacecraft and any type of instrument. At the same time the method is an empirical reconstruction technique that determines the one-dimensional spatial structure of the boundary. The method is illustrated with single- and multi-spacecraft applications using data from Ampte/Irm and Cluster.

    2013-01-01

    Due to the non-storability of electricity and the resulting lack of arbitrage-based arguments to price electricity forward contracts, a significant time-varying risk premium is exhibited. Using EEX data during the introduction of emission certificates and the German “Atom Moratorium” we show that a significant part of the risk premium in electricity forwards is due to different information sets in spot and forward markets. In order to show the existence of the resulting information premium and to analyse its size we design an empirical method based on techniques relating to enlargement of filtrations and the structure of Hilbert spaces. - Highlights: ► Electricity is non-storable and the classical spot–forward-relationship is invalid. ► Future information will cause an information premium for forward contracts. ► We model this premium mathematically using enlargement of filtrations. ► We develop a statistical method testing for the information premium empirically. ► We apply the test to the 2nd phase of the EUETS and the German “Atom Moratorium”

    Full Text Available This essay on cultural studies and the African Diaspora argues for a rethinking of cultural studies in two critical ways: firstly, that cultural studies, from its founding institutional and conceptual moment, cannot but be thought diasporically; and, secondly, that cultural studies be thought ‘out of’, or, against, context—that is, cultural studies is most revealing in its political and literary articulation when it is not read, as many of its advocates claim, contextually. This essay offers a broad critique of cultural studies and the (African diaspora but derives its most cogent and creative argument from its ability to read together the work of two diasporic authors, deracinated South African and Australian writers, J. M. Coetzee and David Malouf.

    Full Text Available During this workshop scholars presented new, mainly empirical studies which explored different aspects of right-wing extremism in Germany. While a number of talks focused on political strategies and modern forms of organization of local neo-Nazi scenes, political elites and the music industry, others had chosen a biographical view on the personal development of young right-wing extremists. Studies on the local context of and conditions for right-wing extremist actions were complemented by representative survey data on political attitudes of German citizens. Apart from discussions about the phenomenon of right-wing extremism itself, participants had the opportunity to exchange their experience of doing empirical qualitative research in a dangerous field.

    Full Text Available Orientation: Past research recognises that human resources management practices may influence innovative behaviour, particularly as compensation systems can be used as a tool to increase intrapreneurial activity. Research purpose: The aim of this study is to determine the relationship between actual versus desired compensation practices and elevated intrapreneurial behaviour. This is in line with research that focuses on how to promote business innovation, rather than merely research whether innovation is desirable for businesses or not. Motivation for the study: Recognising that entrepreneurial actions are the bedrock of intrapreneurial behaviour and that these behaviours may be critical to the long-term vitality of a firm and economy, it is important to facilitate the empirical study of them in an underresearched, emerging market environment. Moreover, compensation such as reward preferences and variable pay schemes remain controversial in terms of their costs versus contributions, and these constructs deserve more empirical research. Research approach, design and method: The study employed a quantitative research design, using a cross-sectional and empirical approach with primary data sources. A structured webbased instrument rendered a sample of 209 respondents from a diverse set of businesses. Canonical correlational analysis was carried out to test the hypotheses. Main findings: The results reveal that a gap exists between an employee’s perception of desired compensation practices and the actual compensation practices. The results further highlight that non-outcome-based measures like pay risk, job risk and expectations of success play a role in determining whether employees decide to be intrapreneurial or not. Practical/managerial implications: Due to the potential impact rewards have on intrapreneurial behaviour, it is necessary to design relevant compensation systems as part of organisational architecture in order to foster

    2012-08-01

    Full Text Available The classification of building facade images is a challenging problem that receives a great deal of attention in the photogrammetry community. Image classification is critically dependent on the features. In this paper, we perform an empirical feature evaluation task for building facade images. Feature sets we choose are basic features, color features, histogram features, Peucker features, texture features, and SIFT features. We present an approach for region-wise labeling using an efficient randomized decision forest classifier and local features. We conduct our experiments with building facade image classification on the eTRIMS dataset, where our focus is the object classes building, car, door, pavement, road, sky, vegetation, and window.

  5. Empirical Study on Arbitrage Opportunities in China Copper Futures Market

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    No-arbitrage bound is established with no-arbitrage theory considering all kinds of trade costs, different deposit and loan interest rate, margin and tax in fuuaes markets. The empirical results find that there are many lower bound arbitrage opportunities in China copper futures market from August 8th, 2003 to August 16th, 2005. Concretely, no-arbitrage opportunity is dominant and lower bound arbitrage is narrow in normal market segment. Lower bound arbitrage almost always exists with huge magnitude in inverted market segment. There is basically no-arbitrage in normal market because spot volume is enough, so that upper or lower bound arbitrage can be realized. There is mostly lower bound arbitrage in inverted market because spot volume is lack.

  6. AN EMPIRICAL STUDY OF MARKETING COMMUNICATIONS EFFECTIVENESS IN SLOVENIAN MARKET

    2014-01-01

    Full Text Available This paper deals with the value or more specifically, the contribution of marketing communications strategy to effectiveness of marketing communications and hypothesizes that marketing communications strategy correlate with the effectiveness of marketing communications. The paper consists of two parts: the theoretical framework for the role of marketing communications strategy for the effectiveness of the marketing communications and the empirical analysis, based on the primary data collected. The concept of the marketing communication effectiveness assumes that there are variables that can have a positive influence on the effectiveness of marketing communications, which incorporates facets of the marketing communication strategy and bidirectional communications. The results suggest that Slovenian organisations which design and implement marketing communication strategy, also have more effective marketing communications. The development of marketing communications strategy was correlated with increased effectiveness of marketing communications in their organisation. Managerial implications are discussed along with directions for further research.

    Communication is a key competence for health care professionals. Analysis of registrar and GP communication performance in daily practice, however, suggests a suboptimal application of communication skills. The influence of context factors could reveal why communication performance levels, on average, do not appear adequate. The context of daily practice may require different skills or specific ways of handling these skills, whereas communication skills are mostly treated as generic. So far no empirical analysis of the context has been made. Our aim was to identify context factors that could be related to GP communication. A purposive sample of real-life videotaped GP consultations was analyzed (N = 17). As a frame of reference we chose the MAAS-Global, a widely used assessment instrument for medical communication. By inductive reasoning, we analyzed the GP behaviour in the consultation leading to poor item scores on the MAAS-Global. In these cases we looked for the presence of an intervening context factor, and how this might explain the actual GP communication behaviour. We reached saturation after having viewed 17 consultations. We identified 19 context factors that could potentially explain the deviation from generic recommendations on communication skills. These context factors can be categorized into doctor-related, patient-related, and consultation-related factors. Several context factors seem to influence doctor-patient communication, requiring the GP to apply communication skills differently from recommendations on communication. From this study we conclude that there is a need to explicitly account for context factors in the assessment of GP (and GP registrar) communication performance. The next step is to validate our findings.

    Heinzelmann, Nora; Ugazio, Giuseppe; Tobler, Philippe N.

    2012-01-01

    This paper considers the practical question of why people do not behave in the way they ought to behave. This question is a practical one, reaching both into the normative and descriptive domains of morality. That is, it concerns moral norms as well as empirical facts. We argue that two main problems usually keep us form acting and judging in a morally decent way: firstly, we make mistakes in moral reasoning. Secondly, even when we know how to act and judge, we still fail to meet the requirements due to personal weaknesses. This discussion naturally leads us to another question: can we narrow the gap between what people are morally required to do and what they actually do? We discuss findings from neuroscience, economics, and psychology, considering how we might bring our moral behavior better in line with moral theory. Potentially fruitful means include nudging, training, pharmacological enhancement, and brain stimulation. We conclude by raising the question of whether such methods could and should be implemented.

    Full Text Available The objective of this study was to investigate whether the investment in maize research was adequate and balanced in Nepalese context. Resource use in maize research was empirically studied with standard congruency analysis by using Full Time Equivalent (FTE of researchers as a proxy measure of investment. The number of researchers involved in maize was 61 but it was only 21.25 on FTE basis, indicating that full time researchers were very few as compared to the cultivated area of maize in the country. Statistical analysis revealed that the investment in maize research was higher in Tarai and lower in the Hills. Congruency index on actual production basis was found low across the eco-zones and even lower across the geographical regions indicating that the investment in maize research was a mismatch and not justified. While adjusted with the equity factor and the research progress factor in the analysis substantial difference was not found in congruency index. This study recommends that substantial increase in investment in maize research is needed with balanced and justified manner across the eco-zones and the geographical regions. Hills need special attention to increase the investment as maize output value is higher in this eco-zone. Eastern and western regions also need increased investment in maize according to their contribution in the output value.

    It is well known that the Information and Communication Technologies (ICT) are important to assist people with disability in the workplace. In this context, this paper sheds light on the state of ICT accessibility for Italian employees with disabilities in private sector companies by mapping and critically analyzing the assistive role of ICT. To do this, empirical evidence was drawn from a multi-methods research with middle and top managers from 97 medium and large Italian companies. Quantitative data was collected using a survey was directed at personnel identified as Human Resource (HR) and Information System (IS) managers, followed by a qualitative study with selected firms whose aim was to understand the inner workings of assistive technology and the decision making process related to assistive technology acquisition and use. The main results show the role and the integration level of people with disabilities, and the presence and effectiveness of specific assistive technologies. Ways to improve the inclusion of people with disability in the workplace, as well as the use of assistive technologies are discussed. ICT could be more disseminated within companies and best used with modifications to improve usability.

    Konsek, Marion B.; Reed, Daniel A.; Watcharawittayakul, Wittaya

    1987-01-01

    Although previous studies have shown that a large file of overlapping register windows can greatly reduce procedure call/return overhead, the effects of register windows in a multiprogramming environment are poorly understood. This paper investigates the performance of multiprogrammed, reduced instruction set computers (RISCs) as a function of window management strategy. Using an analytic model that reflects context switch and procedure call overheads, we analyze the performance of simple, linearly self-recursive programs. For more complex programs, we present the results of a simulation study. These studies show that a simple strategy that saves all windows prior to a context switch, but restores only a single window following a context switch, performs near optimally.

    2009-10-01

    The research reported in this article aims to demonstrate a method for the systematic study of the therapist/patient interaction in psychoanalytic psychotherapy, drawing upon the tradition and methods of 'pragmatics'--the study of language in interaction. A brief introduction to the discipline of pragmatics demonstrates its relevance to the contemporary focus of clinical theory on the here-and-now dynamics of the relationship between analyst and patient. This is followed by a detailed study of five segments from the transcript of a therapeutic dialogue, drawn from a brief psychoanalytic psychotherapy, in which therapist and patient negotiate the meaning of the patient's symptom: Is it psychosomatic? The research seeks to show how the therapeutic process can be observed and studied as an interactional achievement, grounded in general and well-studied procedures through which meaning is intersubjectively developed and shared. Implications of the analysis for clinical theory and practice, and further research, are discussed.

    2012-06-01

    Full Text Available In the current market where severe competition, rapid technological changes and developments take place in a global platform, companies must adapt to the developments and changes to be able to continue their being, not to fall behind time and to increase their profits. Companies which know their customers well, satisfy their expectations, needs and present the best products and services which best fit their wants, will gain competitive advantage. As well as having a need for products and services, also detecting what this need really means to the consumers are among important factors which generate consumers buying behaviour. The concept of “innovation” which is an important factor in consumers buying behaviour, is gradually increasing it’s importance. Companies aim at being innovative in their long term strategies, and being perceived like this by the consumers. Especially, perceived product based innovation by consumers is related with concepts as personal identity, social status, hedonic and utilitarian shopping. In this study, it is aimed to detect the interactions between; product based innovation, consumers personal innovation tendency, the meaning of purchase and consumption in means of identity, hedonic and utilitarian consumption behaviour. For this, a survey was applied to university students. The relations between the variables were defined by the analysis. In this concept, relations were detected between; product based innovation, hedonic and utilitarian consumption, social identity function of consumption and personal innovation tendencies.

    Full Text Available bsenteeism is a major challenge for any organization in the current competitive world. Curbing absenteeism helps organizations achieve their targets and increases productivity. This study highlights the major causes of absenteeism in the production division of a garment industry under various dimensions, which influence on absenteeism like work environment, organizational culture, relation and co-operation, compensation and rewards, facilities, job satisfactory and security, and general factors. The Study helps to identify reasons for employee absenteeism in production division. Sample of 180 employees responses were considered for the study from the universe and the data were analysed, statistically. The study shows that the major factors like wages, other source of income, and bad relationship with supervisors were contributing to the major absence of employees from work. This clearly indicates that work environment, relation and co-operation, facilities provided by the organization and job satisfaction were the main components which are causing the employee absenteeism.

Findings and implications – The study found that customers have favorable experiences when buying life insurance through the bancassurance channel. There are seven core factors that affect customer experience in bancassurance: ease of buying, whether maturity benefit is received, reliability of the channel, responsiveness of the channel, after-sale services, stock market-related information, and accuracy of the channel. Banks should devise a strategy to sustain favorable experiences of their customers, as this enables banks to retain their existing customers while also attracting new ones. Limitation – The study is restricted to customers buying life insurance policy from various branches of State Bank of India in Guwahati, India. Therefore, longitudinal and cross-sectional research is needed to generalize the findings. Originality – The study is first of its kind and hence original in nature.

    Lai, Ivan K. W.; Lai, Donny C. F.

    2014-06-01

    This study aims to examine the positive and negative factors that can significantly explain user acceptance of mobile commerce (m-commerce) in Macau. A technology acceptance model for m-commerce with five factors is constructed. The proposed model is tested using data collected from 219 respondents. Confirmatory factor analysis is performed to examine the reliability and validity of the model, and structural equation modelling is performed to access the relationship between behaviour intention and each factor. The acceptance of m-commerce is influenced by factors including performance expectancy, social influence, facilitating conditions and privacy concern; while effort expectancy is insignificant in this case. The results of the study are useful for m-commerce service providers to adjust their strategies for promoting m-commerce services. This study contributes to the practice by providing a user technology acceptance model for m-commerce that can be used as a foundation for future research.

  16. Website Service Quality in Ireland: An Empirical Study

    Connolly, Regina

    Despite the fact that service quality is a critical determinant of website success, studies show that consumers frequently view the service quality delivered through websites as unsatisfactory. This paper outlines a study that investigated the dimensions of website service excellence valued by Irish customers of a small-to-medium enterprise specialising in gifts. The E-S-QUAL measurement instrument was applied to the customers who purchase products online from this retailer, in order to determine their purchasing patterns and the dimensions of e-service quality that they value. The results of this study indicate the effectiveness of the instrument in determining gaps in e-service quality. The findings will be of benefit both to practitioners and researchers seeking to improve their understanding of the factors that contribute towards the creation and maintenance of consumer satisfaction in Irish online transactions.

    Full Text Available This study aims to suggest best practices for improving the effectiveness of entrepreneurship education programs in the European area, based on their impact on expected attitudes of undergraduate students towards business startup as a career choice. Particularly, the paper presents some results from a study carried out in two Spanish universities aimed at validating a structure of entrepreneurship education based on a double component of curricular teaching and extracurricular support, and to analyze their effect upon undergraduates’ entrepreneurial selfefficacy and outcome expectations as immediate antecedents of entrepreneurial intentions and behaviors. Sample was comprised of 800 university students, and statistical treatment of data was based on factorial and regression analyses. Findings underline the very limited involvement of Spanish universities in entrepreneurship education as perceived by students, together with the existence of different effects of curricular and extracurricular elements when fostering entrepreneurial careers among future graduates. Implications of these results and limitations of the study are discussed.

    2012-07-15

    This paper examines the determinants of recycling behaviour among 200 university students from the perspective of the theory of planned behaviour (TPB). Data was analysed using Structural Equation Modelling technique. Findings indicate that environmental awareness was significantly related to attitude towards recycling, whilst attitude and social norms had significant impact on recycling behaviour. However, convenience and cost of recycling were not significant reasons for recycling. The study has enhanced the understanding of the determinants of recycling behaviour and has implications for schools and governmental agencies in educating and encouraging positive recycling behaviour. It also confirms the appropriateness of the TPB in examining studies of this nature. Further suggestions for future research are offered. Copyright © 2012 Elsevier Ltd. All rights reserved.

  16. Portuguese validation of the Internet Addiction Test: An empirical study.

    Science.gov (United States)

    2014-06-01

    Research into Internet addiction (IA) has increased greatly over the last decade. Despite its various definitions and general lack of consensus regarding its conceptualisation amongst researchers, instruments for measuring this phenomenon have proliferated in a number of countries. There has been little research on IA in Portugal and this may be partly due to the absence of standardised measurement tools for assessing IA. This study attempted to address this issue by adapting a Portuguese version of the Internet Addiction Test (IAT) via a translation-back translation process and Confirmatory Factor Analysis in a sample of 593 Portuguese students that completed a Portuguese version of the IAT along with questions related to socio-demographic variables. The findings suggested that the IAT appears to be a valid and reliable instrument for measuring IA among Portuguese young adults as demonstrated by its satisfactory psychometric properties. However, the present findings also suggest the need to reword and update some of the IAT's items. Prevalence of IA found in the sample was 1.2% and is discussed alongside findings relating to socio-demographic correlates. Limitations and implications of the present study are also discussed. The present study calls for a reflection of the IAT while also contributing to a better understanding of the basic aspects of IA in the Portuguese community since many health practitioners are starting to realise that Internet use may pose a risk for some individuals.

  17. Efficient management of marine resources in conflict: an empirical study of marine sand mining, Korea.

    Science.gov (United States)

    Kim, Tae-Goun

    2009-10-01

    This article develops a dynamic model of efficient use of exhaustible marine sand resources in the context of marine mining externalities. The classical Hotelling extraction model is applied to sand mining in Ongjin, Korea and extended to include the estimated marginal external costs that mining imposes on marine fisheries. The socially efficient sand extraction plan is compared with the extraction paths suggested by scientific research. If marginal environmental costs are correctly estimated, the developed efficient extraction plan considering the resource rent may increase the social welfare and reduce the conflicts among the marine sand resource users. The empirical results are interpreted with an emphasis on guidelines for coastal resource management policy.

    Full Text Available The theory of capital structure has advanced remarkably. This development began as many firms had options to consider various external factors determining the composition of debt and equity. Not only the asymmetric information or the conflict among bondholders and shareholders initiated the Pecking Order Theory and the Static Trade-off Theory respectively but also the overvalued or undervalued of stock price had to be taken as a determinant factor for identifying the ideal debt-equity mix. The author maintains these factors as they were pioneers to this theory on Market Timing Theory (MTT introduced by Baker and Wurgler (2002. The essence of this theory is described when stock prices are overvalued, firms will finance projects through debts, otherwise the firms will be undervalued and be relied on equity financing. Using the methodology introduced by Baker and Wurgler (2002, the author selected only samples of IPOs of firms during 2008-2009 to limit the scope of this study.

This study concludes that the market-to-book ratio has a negative effect on the market leverage. The implication is that when firms achieve certain level of earnings growth, the stock price will be overvalued, so it would be the right timing for firms to proceed equity financing. Under the robustness test with GLS Random Effect, the hypothèses of MTT is supported.

  1. Empirical study on voting power in participatory forest planning.

    Vainikainen, N; Kangas, A; Kangas, J

    2008-07-01

    Multicriteria decision support systems are applied in natural resource management in order to clarify the planning process for the stakeholders, to make all available information usable and all objectives manageable. Especially when the public is involved in planning, the decision support system should be easy to comprehend, transparent and fair. Social choice theory has recently been applied to group decision-making in natural resources management to accomplish these objectives. Although voting forms the basis of democracy, and is usually taken as a fair method, the influence of voters over the outcome may vary. It is also possible to vote strategically to improve the results from each stakeholder's point of view. This study examines the use of social choice theory in revealing stakeholders' preferences in participatory forest planning, and the influence of different voters on the outcome. The positional voting rules examined were approval voting and Borda count, but both rules were slightly modified for the purposes of this study. The third rule examined, cumulative rule, resembles utilitarian voting rules. The voting rules were tested in a real participatory forest planning situation in eastern Lapland, Finland. All voting rules resulted in a different joint order of importance of the criteria. Yet, the preference orders produced had also a lot in common and the criteria could be divided into three quite distinct groups according to their importance. The influence of individual voters varied between the voting rules, and in each case different voter was the most influential.

It identifies the framework of corporate governance, which has here been set into two dimensions – institutionalisations and regulations – and describes the five major principles of corporate governance. The study was carried out by interviews with key employees and the review of related laws and selected annual reports. The study found (1 basic shareholder rights were honoured in decision-making, except for large decisions such as major asset sales; (2 shareholders were not treated equitably in practice, although controllers sometimes took action and prohibited insider trading; (3 the role and rights of stakeholders in corporate governance were respected, and stakeholders had a number of legal protections, which were largely covered in Jordan's Company Law; (4 disclosure and transparency were observed to a large extent, although limited to quantity rather than quality, because Jordan has fully adopted IFRS and ISA and (5 boards largely fulfilled their responsibilities, as these are extensively defined by law and regulation.

    1993-01-01

    Prevalence of mental disorders in 62 battered women receiving services from a Florida battered woman agency was identified by means of a structured interview, the Diagnostic Interview Schedule. Of the total sample of battered women, 30 were in a shelter operated by the agency and 32 were living in their own homes and receiving assistance from the agency. Resultant diagnoses met diagnostic criteria developed in the Diagnostic and Statistical Manual (3rd. ed.) of the American Psychiatric Association. The Diagnostic Interview Schedule is a 263 item structured interview used in the National Institute of Mental Health Epidemiological Catchment Area program carried out in the early 1980s. The Diagnostic Interview Schedule permits the use of 10,953 females in the epidemiological study as a comparison group of normal women. Scoring of the interviews was done by a computer diagnostic program with absolute decision rules. Extremely high prevalence was found for psychosexual dysfunction, major depression, post traumatic stress disorder, generalized anxiety disorder, and obsessive compulsive disorder. These diagnoses appear to reflect the major components of the battered woman syndrome developed by Lenore Walker and the study approximates Walker's request for improved methodology in the research into the psychology of the battered woman.

    2014-06-01

    Full Text Available Understanding how technology investments create business value is a research priority in today's technology-intensive world. Drawing on a literature review as well as a qualitative study, this research suggests that sales technology can support both: externally focused tasks towards managing customer relationships and internal administrative tasks. To unleash its real potential, sales technology should be designed to enable customer relationships rather than being perceived as a cost cutting tool. Today organisations are forced to constantly invent new ways of interacting with the customer to increase customer loyalty and to decrease the possibility of commoditization. This paper will focus on Sales Force Automation (SFA and its increasing importance. It will explore the purpose of SFA, its advantages and disadvantages, and its future impact on organisations through a qualitative research study: the authors investigated a small company operating in the business-to-business services sector to obtain practical feedback on the organisational and individual implications, the potential benefits and the problems related to adoption of an SFA system.

    Full Text Available Emotional intelligence is very critical to the managerial effectiveness. The present study intends to explore the relationships between emotional intelligence and the three roles such as, interpersonal, informational, and decision of managerial effectiveness. Emotional intelligence is measured by using the Emotional Quotient Index (Rahim et al., 2002 [Rahim, M., Psenicka, C., Polychroniou, P., Zhao, J., Yu, C., Chan, K., Susana, K., Alves, M., Lee, C., Rahman, M.S., Ferdausy, S., & Wyk, R. (2002. A model of emotional intelligence and conflict management strategies: a study in seven countries. International Journal of Organizational Analysis, 10(4, 302-326.] while managerial effectiveness is assessed by using Tsui’s (1984 scale [Tsui, A.S. (1984. A role set analysis of managerial reputation. Organizational Behavior and Human Performance, 34, 64-96.]. Data were collected by distributing self-administered questionnaires among the working MBA students using a convenience sampling technique. Respondents are asked to rate their emotional intelligence and managerial effectiveness scales. Finally 127 usable responses are received and, then, analyzed by using the descriptive statistics, bivariate correlation, and regression analysis. Analysis shows that emotional intelligence was positively related with interpersonal role, informational role, and decision role. The main implication is that emotional intelligence could enhance managerial effectiveness guiding the managers, academics, and professionals. The limitations are the sample size and the sampling technique which might limit the generalizability of the findings. Future directions are also discussed.

    2005-12-01

    The authors study the association between physician leadership styles and leadership effectiveness. Executive directors of community health centers were surveyed (269 respondents; response rate = 40.9 percent) for their perceptions of the medical director's leadership behaviors and effectiveness, using an adapted Multifactor Leadership Questionnaire (43 items on a 0-4 point Likert-type scale), with additional questions on demographics and the center's clinical goals and achievements. The authors hypothesize that transformational leadership would be more positively associated with executive directors' ratings of effectiveness, satisfaction with the leader, and subordinate extra effort, as well as the center's clinical goal achievement, than transactional or laissez-faire leadership. Separate ordinary least squares regressions were used to model each of the effectiveness measures, and general linear model regression was used to model clinical goal achievement. Results support the hypothesis and suggest that physician leadership development using the transformational leadership model may result in improved health care quality and cost control.

Union countries are trying to alleviate the short term effects of the crisis on policy implementation. Whether union countries will ride out the crisis with short term policies can be examined by investigating their financial sustainability. The aim of this study was to examine the European Monetary Union member countries’ financial viability. For this aim we use a balanced panel covering EMU 12 countries (Austria, Belgium, Finland, France, Germany, Luxemburg, Ireland, Portugal, Netherland, Italy, Greece, Spain over the period 1995-2011. We analyzed the relationship between debt/GDP and primary surplus for panel causality covering EMU 12 countries. The results of the panel co-integration tests revealed that the variables are co-integrated. In other words there is statistically significant long-run relationship among the variables.

    Consultation is essential to the daily practice of school psychologists (National Association of School Psychologist, 2010). Successful consultation requires fidelity at both the consultant (implementation) and consultee (intervention) levels. We applied a multidimensional, multilevel conception of fidelity (Dunst, Trivette, & Raab, 2013) to a consultative intervention called the Collaborative Model for Promoting Competence and Success (COMPASS) for students with autism. The study provided 3 main findings. First, multidimensional, multilevel fidelity is a stable construct and increases over time with consultation support. Second, mediation analyses revealed that implementation-level fidelity components had distant, indirect effects on student Individualized Education Program (IEP) outcomes. Third, 3 fidelity components correlated with IEP outcomes: teacher coaching responsiveness at the implementation level, and teacher quality of delivery and student responsiveness at the intervention levels. Implications and future directions are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Full Text Available Tourism and hospitality have become key global economic activities as expectations with regard to our use of leisure time have evolved, attributing greater meaning to our free time. While the growth in tourism has been impressive, India's share in total global tourism arrivals and earnings is quite insignificant. It is an accepted fact that India has tremendous potential for development of tourism. This anomaly and the various underlying factors responsible for it are the focus of our study. The objective being determination of customer preferences for multi attribute hybrid services like tourism, so as to enable the state tourism board to deliver a desired combination of intrinsic attributes, helping it to create a sustainable competitive advantage, leading to greater customer satisfaction and positive word of mouth. Conjoint analysis has been used for this purpose, which estimates the structure of a consumer’s preferences, given his/her overall evaluations of a set of alternatives that are pre-specified in terms of levels of different attributes.

    Full Text Available Most queries that applied on database management systems (DBMS depend heavily on the performance of the used sorting algorithm. In addition to have an efficient sorting algorithm, as a primary feature, stability of such algorithms is a major feature that is needed in performing DBMS queries. In this paper, we study a new Sorting Algorithm for Join Queries (SAJQ that has both advantages of being efficient and stable. The proposed algorithm takes the advantage of using the m-way-merge algorithm in enhancing its time complexity. SAJQ performs the sorting operation in a time complexity of O(nlogm, where n is the length of the input array and m is number of sub-arrays used in sorting. An unsorted input array of length n is arranged into m sorted sub-arrays. The m-way-merge algorithm merges the sorted m sub-arrays into the final output sorted array. The proposed algorithm keeps the stability of the keys intact. An analytical proof has been conducted to prove that, in the worst case, the proposed algorithm has a complexity of O(nlogm. Also, a set of experiments has been performed to investigate the performance of the proposed algorithm. The experimental results have shown that the proposed algorithm outperforms other Stable–Sorting algorithms that are designed for join-based queries.

    Full Text Available There is no doubt that conventional accounting does not provide actual value of a firm since they only take into account the tangible assets. Intellectual capital provides a new concept for considering actual value of the assets, which helps calculate intangible values of the firm. In this paper, we use value added intellectual coefficient (VAIC to measure the performance of a firm. The study investigates the relationship between intellectual capital and return on assets and value added for three consecutive years between 2008 and 2010. The results indicate that there is no meaningful relationship between intellectual capital and return on assets for fiscal years of 2008 and 2009 but there is a meaningful relationship between these two items for the fiscal year of 2010 when . Our findings also indicate that there is no meaningful relationship between intellectual capital and value added for the years of 2008 and 2010 but there is a meaningful relationship between the items for the fiscal year of 2009. The results somewhat confirm the recently published results in the literature, which argues the use of VAIC for assessing the direct impact of IC on other financial factors.

    Personality traits, namely neuroticism, have been suggested as vulnerability factors for the development and maintenance of sexual dysfunction in heterosexual samples. However, no evidence was found regarding homosexual samples. This study aimed to analyze the differences on personality traits between heterosexual and homosexual men and women with and without sexual problems. Participants were 285 individuals (142 men, 143 women) who completed a web-based survey. Participants answered the NEO Five-Factor Inventory, the Brief Symptomatology Inventory, and questions regarding sexual problems. The groups of men and women with and without sexual problems were matched for sociodemographic variables. A 2 (Group) × 2 (Sexual Orientation) multivariate analysis of covariance was conducted separately for each gender. Results indicated a significant main effect for group and for sexual orientation in male and female samples. Men with sexual problems scored higher on neuroticism, whereas women with sexual problems scored higher on neuroticism and lower on extraversion when compared with healthy controls, regardless of sexual orientation. In addition, gay men scored higher on neuroticism and lesbian women scored higher on conscientiousness compared with the heterosexual groups. The present findings emphasize the central role of neuroticism on sexual problems in both men and women regardless of sexual orientation.

    Studies of endurance running have typically involved elite athletes, small sample sizes and measures that require special expertise or equipment. We examined factors associated with race performance and explored methods for race time prediction using information routinely available to a recreational runner. An Internet survey was used to collect data from recreational endurance runners (N = 2303). The cohort was split 2:1 into a training set and validation set to create models to predict race time. Sex, age, BMI and race training were associated with mean race velocity for all race distances. The difference in velocity between males and females decreased with increasing distance. Tempo runs were more strongly associated with velocity for shorter distances, while typical weekly training mileage and interval training had similar associations with velocity for all race distances. The commonly used Riegel formula for race time prediction was well-calibrated for races up to a half-marathon, but dramatically underestimated marathon time, giving times at least 10 min too fast for half of runners. We built two models to predict marathon time. The mean squared error for Riegel was 381 compared to 228 (model based on one prior race) and 208 (model based on two prior races). Our findings can be used to inform race training and to provide more accurate race time predictions for better pacing.

    Full Text Available The purpose of this paper to identify factors which have a bearing on compliance with medical advice in various age groups. The survey was conducted, using the CAWI method, on a representative sample of 1000 respondents who declared having used healthcare services in the previous six months. Control of competences is one of the strongest factors which is common for the oldest and youngest groups. Interestingly, trust in the integrity and honesty of doctors is significant for the youngest patients, i.e., the higher is the level of trust, the lower is the tendency to non-comply. Another type of trust is related to the benevolence of doctors and is significant to patients of the middle age group. Satisfaction is a significant predictor in the two oldest groups of patients. High levels of satisfaction seem to deter people from non-adherence to recommended treatment regimens. The results of the present study provide knowledge about the nature and diversity of factors behind patient compliance in various age groups.

    2007-02-01

    Playing videogames is now a major leisure pursuit, yet research in the area is comparatively sparse. Previous correlational evidence suggests that subjective time loss occurs during playing videogames. This study examined experiences of time loss among a relatively large group of gamers (n = 280). Quantitative and qualitative data were collected through an online survey. Results showed that time loss occurred irrespective of gender, age, or frequency of play, but was associated with particular structural characteristics of games such as their complexity, the presence of multi-levels, missions and/or high scores, multiplayer interactions, and plot. Results also demonstrated that time loss could have both positive and negative outcomes for players. Positive aspects of time loss included helping players to relax and temporarily escape from reality. Negative aspects included the sacrificing of other things in their lives, guilty feelings about wasted time, and social conflict. It is concluded that for many gamers, losing track of time is a positive experience and is one of the main reasons for playing videogames.

    Our research on non-religion supports the proposed shift toward more interactive models of prejudice. Being nonreligious is easily hideable and, increasingly, of low salience, leading to experiences not easily understood via traditional or contemporary frameworks for studying prejudice and prejudice reduction. This context affords new opportunity to observe reverse forms of interactive prejudice, which can interfere with prejudice reduction.

    Aversano, Lerina; Tortorella, Maria

    Software systems mainly considered from enterprises for dealing with a business process automation belong to the following two categories: Workflow Management Systems (WfMS) and Enterprise Resource Planning (ERP) systems. The wider diffusion of ERP systems tends to favourite this solution, but there are several limitations of most ERP systems for automating business processes. This paper reports an empirical study aiming at comparing the ability of implementing business processes of ERP systems and WfMSs. Two different case studies have been considered in the empirical study. It evaluates and analyses the correctness and completeness of the process models implemented by using ERP and WfM systems.

    Directory of Open Access Journals (Sweden)

    Wing Yin Chan

    2016-01-01

    Full Text Available This study investigates tourist consumption responses toward tourism innovation. To measure tourist responses, this study posits three key consumption drivers, namely social esteem, desire for experiential travel, and avoidance against rituality of tourism settings (a subscale of need for uniqueness and models consumers’ affective response within the context of tourism innovation. It involves 295 respondents in an empirical survey. The findings affirm the three drivers toward tourist consumption behavior. Avoidance of rituality reflects tourist preference toward tourism product and service innovation. Desire for experiential travel and the pursuit of social esteem signify tourism management and marketing innovation. Social esteem, need for status and creative choice have significant influence on tourists’ affective responses. Acquiring unique tourist products, desire for experiential travel and seeking social esteem are important motivations for tourist consumption. The implications of the study enrich the existing literature of consumer behavior and tourist consumption in response to tourism innovation.

    2014-01-01

    Full Text Available Purpose: Many global organizations have aligned their strategy and operation via the ISO-based framework of integrated management system (IMS that allows them to merge quality, environment, health and safety management systems. In such context, having a robust electronic document management system (EDMS is essential, especially at global enterprises where a large amount of documents generated by processes flows through different work cultures. However, there is no "one-size-fits-all" design for EDMS because it depends on organizations' needs, size and resource allocation. This article discusses the interrelation between EDMS and IMS in order to suggest a best practice. Design/methodology/approach: This article methodologically based upon a qualitative, interpretivistic, longitudinal empirical study in a wind turbine factory. Findings and Originality/value: IMS improvement and effectiveness has been overlooking EDMS as a key factor in establishing appropriate technological support of the IMS processes. Rightful application of EDMS can further contribute to organizational learning, precision of documentation and cross-organisational collaboration. Research limitations/implications: Theorising on IMS needs a stronger perspective of the technological limitations and potentials of basing IMS on EDMS. Practical implications: IMS are complex systems involving a large number of administrative functions. EDMS provides a formal representation with automation potentials both heightening and securing document trustworthiness. Social implications: IMS has a tendency to stay with professionals, e.g. line managers and QA/QC/QMS professionals. The EDMS line of discussion suggests a broader inclusion. Originality/value: Researching IMS as a technological implementation is giving a better platform of aligning the IMS with other business processes and is bringing IMS closer to the operational activities within the enterprise.

  9. Making Strategic Planning Work in Local Government: An Empirical Study of Success And Failure

    2015-10-01

    Full Text Available Since the 1990s, local governments all over Europe have launched reforms to improve local democracy, public management and efficiency in the provision of local services. Some of these reforms are inspired by what previously has worked in private management and some of them have also a macro-level approach, whose main aim is to introduce institutional reforms and reorganizations to ensure contextual problem solving by strengthening governance within the local public sector. In this context, Strategic Planning in public organizations has attracted interest among academic researchers and practitioners as an instrument for dealing with a complex environment and for the achievement of higher performance and the attainment of greater democracy. But the decision on how to introduce Strategic Planning might follow a different rationale. The hypothesis maintained in this paper is that those that are based in an endogenous rationale are more likely to succeed. To test our hypothesis this paper draws on a comparative empirical analysis concerning the design and implementation of a Strategic Planning process within two Spanish city governments: one considered to have been a failure and the other a success. Focusing on the way in which the use of Strategic Planning has to face the trade-offs between urban and economic development and democracy, the paper explores how this formal mechanism of citizen´s and business’ participation serves to establish relational processes to reinvigorate local economic development, democracy and administrative modernization only when a strong political and administrative leadership is put into motion. Overall, the study yields evidence consistent with the notion that a successful Strategic Planning at the local level has to take into account not only institutional issues, but also the communal, social and political resources that frame the deliberations propelled by the Strategic Planning process.

    Full Text Available The current context of globalization, financial markets mondialisation, internationalization of production and intensification of international trade relations represents references that justify the need for an international project of reducing international accounting differences between the local accounting referential. Recent developments in the area of financial reports improvements interest devotes international accounting convergence solution as the way forward. Regardless of the approach chosen by each country in the process of international accounting convergence, the situation of conflict situation between state vs. accounting profession persists nowadays. This situation has led to the establishment of a dual financial reporting system at the national level, not at all beneficial to the users of financial information. The success of international accounting convergence process is reduced to the level of the consolidated financial statements of listed companies. The next step that needs to be done is also to provide solutions of accounting convergence to the rest of the companies, and also to extend the normalization process for the statutory financial statements too. Positive effects of international accounting referential, confirmed by recent studies, become a solid base for adopting IFRS for statutory financial statements too. The main impediment that needs to be eliminated is to convince the state that this step is appropriate for all players of accounting information market. Considering romanian current situation, where from now IFRS is used to report the statutory financial statements of listed companies too, we try, by an empirical approach at the level of BVB, to look for the impact of such a legislative change. The main objective is to check if the state budget is affected consistently, and also take a look on the economic effects of IFRS adoption gained by companies, especially on evolution of rate-of-equity and short

    Modification of empirical antimicrobials when warranted by culture results or clinical signs is recommended to control antimicrobial overuse and resistance. We aimed to assess the frequency with which patients were started on empirical antimicrobials, characteristics of the empirical regimen and the clinical characteristics of patients at the time of starting antimicrobials, patterns of changes to empirical therapy at different timepoints, and modifiable factors associated with changes to the initial empirical regimen in the first 5 days of therapy. We did a chart review of adult inpatients receiving one or more antimicrobials in six US hospitals on 4 days during 2009 and 2010. Our primary outcome was the modification of antimicrobial regimen on or before the 5th day of empirical therapy, analysed as a three-category variable. Bivariate analyses were used to establish demographic and clinical variables associated with the outcome. Variables with p values below 0·1 were included in a multivariable generalised linear latent and mixed model with multinomial logit link to adjust for clustering within hospitals and accommodate a non-binary outcome variable. Across the six study sites, 4119 (60%) of 6812 inpatients received antimicrobials. Of 1200 randomly selected patients with active antimicrobials, 730 (61%) met inclusion criteria. At the start of therapy, 220 (30%) patients were afebrile and had normal white blood cell counts. Appropriate cultures were collected from 432 (59%) patients, and 250 (58%) were negative. By the 5th day of therapy, 12·5% of empirical antimicrobials were escalated, 21·5% were narrowed or discontinued, and 66·4% were unchanged. Narrowing or discontinuation was more likely when cultures were collected at the start of therapy (adjusted OR 1·68, 95% CI 1·05-2·70) and no infection was noted on an initial radiological study (1·76, 1·11-2·79). Escalation was associated with multiple infection sites (2·54, 1·34-4·83) and a positive

Yet there are few empirical studies to inform our understanding of the vulnerabilities and resilience of complex infrastructure systems in disasters. This research takes a systems thinking approach to explore the dynamic behaviour of a network of essential services, in the presence and absence of volcanic ashfall hazards in Montserrat, West Indies. Adopting a case study methodology and qualitative methods to gather empirical data, we centre the study on the healthcare system and its interconnected network of essential services. We identify different types of relationship between sectors and develop a new interdependence classification system for analysis. Relationships are further categorised by hazard conditions, for use in extensive risk contexts. During heightened volcanic activity, relationships between systems transform in both number and type: connections increase across the network by 41%, and adapt to increase cooperation and information sharing. Interconnections add capacities to the network, increasing the resilience of prioritised sectors. This in-depth and context-specific approach provides a new methodology for studying the dynamics of infrastructure interdependence in an extensive risk context, and can be adapted for use in other hazard contexts.

    2016-09-01

    Full Text Available In this paper we address the issue of knowledge transfer between organizations in partnerships as well as the role of the knowledge exchange in building successful cooperation. Given its many positive effects on the business performance, such as creativity, innovativeness and flexibility needed in modern business environment, it was of the utmost importance to investigate different factors that either contribute or constrain learning in alliances. After the theoretical background on the aforementioned topic was given, an empirical research and its main conclusions were described in the paper. A study of the alliances in Croatian context revealed that organizational characteristics exhibit the most pronounced influence on the knowledge transfer success which was especially highlighted in domestic alliances. The level of integration, the primary area of cooperation and the previous experience in forming alliances between partners did not change the extent to which different factors influenced knowledge transfer.

    2016-05-01

    Full Text Available Today, it is common for software projects to collect measurement data through development processes. With these data, defect prediction software can try to estimate the defect proneness of a software module, with the objective of assisting and guiding software practitioners. With timely and accurate defect predictions, practitioners can focus their limited testing resources on higher risk areas. This paper reports the results of three empirical studies that uses an automated genetic defect prediction framework. This framework generates and compares different learning schemes (preprocessing + attribute selection + learning algorithms and selects the best one using a genetic algorithm, with the objective to estimate the defect proneness of a software module. The first empirical study is a performance comparison of our framework with the most important framework of the literature. The second empirical study is a performance and runtime comparison between our framework and an exhaustive framework. The third empirical study is a sensitivity analysis. The last empirical study, is our main contribution in this paper. Performance of the software development defect prediction models (using AUC, Area Under the Curve was validated using NASA-MDP and PROMISE data sets. Seventeen data sets from NASA-MDP (13 and PROMISE (4 projects were analyzed running a NxM-fold cross-validation. A genetic algorithm was used to select the components of the learning schemes automatically, and to assess and report the results. Our results reported similar performance between frameworks. Our framework reported better runtime than exhaustive framework. Finally, we reported the best configuration according to sensitivity analysis.

    Full Text Available Abstract Background The lack of standardized criteria for defining chronic fatigue syndrome (CFS has constrained research. The objective of this study was to apply the 1994 CFS criteria by standardized reproducible criteria. Methods This population-based case control study enrolled 227 adults identified from the population of Wichita with: (1 CFS (n = 58; (2 non-fatigued controls matched to CFS on sex, race, age and body mass index (n = 55; (3 persons with medically unexplained fatigue not CFS, which we term ISF (n = 59; (4 CFS accompanied by melancholic depression (n = 27; and (5 ISF plus melancholic depression (n = 28. Participants were admitted to a hospital for two days and underwent medical history and physical examination, the Diagnostic Interview Schedule, and laboratory testing to identify medical and psychiatric conditions exclusionary for CFS. Illness classification at the time of the clinical study utilized two algorithms: (1 the same criteria as in the surveillance study; (2 a standardized clinically empirical algorithm based on quantitative assessment of the major domains of CFS (impairment, fatigue, and accompanying symptoms. Results One hundred and sixty-four participants had no exclusionary conditions at the time of this study. Clinically empirical classification identified 43 subjects as CFS, 57 as ISF, and 64 as not ill. There was minimal association between the empirical classification and classification by the surveillance criteria. Subjects empirically classified as CFS had significantly worse impairment (evaluated by the SF-36, more severe fatigue (documented by the multidimensional fatigue inventory, more frequent and severe accompanying symptoms than those with ISF, who in turn had significantly worse scores than the not ill; this was not true for classification by the surveillance algorithm. Conclusion The empirical definition includes all aspects of CFS specified in the 1994 case definition and identifies persons with

  7. For a new dialogue between theoretical and empirical studies in evo-devo

    Directory of Open Access Journals (Sweden)

    Giuseppe eFusco

    2015-08-01

    Full Text Available Despite its potentially broad scope, current evo-devo research is largely dominated by empirical developmental studies, whereas comparably little role is played by theoretical research. I argue that this represents an obstacle to a wider appreciation of evo-devo and its integration within a more comprehensive evolutionary theory, and that this situation is causally linked to a limited exchange between theoretical and experimental studies in evo-devo. I discuss some features of current theoretical work in evo-devo, highlighting some possibly concurring impediments to an effective dialogue with experimental studies. Finally, I advance two suggestions for enhancing fruitful cross-fertilization between theoretical and empirical studies in evo-devo: i to broaden the scope of evo-devo beyond its current conceptualization, teaming up with other variational approaches to the study of evolution, and ii to develop more effective forms of scientific interaction and communication.

    2014-09-23

    The current financial crisis and the increasing burden of chronic diseases are challenging hospitals to enhance their innovation capacity to deliver new and more effective health services. However, the shortage of skills has been widely recognized as a key obstacle for innovation. Ensuring the presence of a skilled workforce has become a priority for the health system in Portugal and across Europe. The aim of this study was to examine the demand of new skills and their influence in both investments in innovation and development of skills. We used a mixed-methods approach combining statistical analysis of data survey and content analysis of semistructured interviews with the Administration Boards of hospitals, using a nominal group technique. The results illustrate an increasing demand of a broad range of skills for innovation development, including responsibility and quality consciousness (with a significant increase of 55%, 52/95), adaptation skills (with an increase of 44%, 42/95) and cooperation and communication skills (with an increase of 55%, 52/95). Investments in the development of skills for innovation are mainly focused on aligning professional training with an organizational strategy (69%, 66/95) as well as collaboration in taskforces (61%, 58/95) and cross-department teams (60%, 57/95). However, the dynamics between the supply and demand of skills for innovation are better explained through a broader perspective of organizational changes towards enhancing learning opportunities and engagement of health professionals to boost innovation. The results of this study illustrate that hospitals are unlikely to enhance their innovation capacity if they pursue strategies failing to match the skills needed. Within this context, hospitals with high investments in innovation tend to invest more in skills development. The demand of skills and investments in training are influenced by many other factors, including the hospital's strategies, as well as changes in the

  10. An Empirical Study of Atmospheric Correction Procedures for Regional Infrasound Amplitudes with Ground Truth.

    Science.gov (United States)

    Howard, J. E.

    2014-12-01

    This study focusses on improving methods of accounting for atmospheric effects on infrasound amplitudes observed on arrays at regional distances in the southwestern United States. Recordings at ranges of 150 to nearly 300 km from a repeating ground truth source of small HE explosions are used. The explosions range in actual weight from approximately 2000-4000 lbs. and are detonated year-round which provides signals for a wide range of atmospheric conditions. Three methods of correcting the observed amplitudes for atmospheric effects are investigated with the data set. The first corrects amplitudes for upper stratospheric wind as developed by Mutschlecner and Whitaker (1999) and uses the average wind speed between 45-55 km altitudes in the direction of propagation to derive an empirical correction formula. This approach was developed using large chemical and nuclear explosions and is tested with the smaller explosions for which shorter wavelengths cause the energy to be scattered by the smaller scale structure of the atmosphere. The second approach isa semi-empirical method using ray tracing to determine wind speed at ray turning heights where the wind estimates replace the wind values in the existing formula. Finally, parabolic equation (PE) modeling is used to predict the amplitudes at the arrays at 1 Hz. The PE amplitudes are compared to the observed amplitudes with a narrow band filter centered at 1 Hz. An analysis is performed of the conditions under which the empirical and semi-empirical methods fail and full wave methods must be used.

  11. An Exploratory Study of Presenteeism in Turkish Context

    2016-02-01

    Full Text Available Presenteeism has been an emerging research era, where many exploratory questions may be produced. Literature is not very definitive for the conceptualization of the construct in many aspects. There are few studies about the reasons, measurement approaches and positive outcomes of the concept. Studies conducted in Turkish context are even fewer. Paper combines two studies; first study aims to investigate different conceptualizations, possible reasons, negative and positive outcomes of presenteeism. The purpose of the second study is to find out how those concepts structure and relate to each other. Findings provide useful insights for reasons, outcomes and criteria of presenteeism. They also indicate different conceptualization of the concept and there are significant relationships between variables according to the research.

    2003-01-01

    Balancing the polarized notions of quality and quantity of service and care is a challenge for the 21st century health and social service system. The expectation of transparent decision making at both the policy and the practice level of case management has forced practitioners to seek guidance in ethical decision making. Case management, as a system, has potential to lead this new practice approach by incorporating the principles of ethical decision making in planning and coordinating care. A recent case study of ethical decision making within the bureaucratic context offers some insight and learning and may help inform future practice.

  1. Energy structure, marginal efficiency and substitution rate: An empirical study of China

    2007-01-01

    Energy efficiency is an important factor in developing energy policies as it represents the extent to which resources support economic output. In recent literature, relevant studies have mainly focused on aggregate energy efficiency, but rarely touched on the marginal efficiency of diverse energy resources and their comparative substitution rate. During 1978-2003, China's energy efficiency continually increased; and consequently became a hot topic in contemporary literature. However, there is no empirical study on the relationship between energy structure and energy efficiency. In order to close the gap, this paper reports the empirical study of the impact of China's energy structure on its energy efficiency from 1978 to 2003. The work covered primary estimation of the marginal efficiency of coal and petroleum in China, as well as the comparative substitution rate. Results indicate that the substitution rate between petroleum and coal is a factor of 5.38

  2. An integrated developmental model for studying identity content in context.

    Science.gov (United States)

    Galliher, Renee V; McLean, Kate C; Syed, Moin

    2017-11-01

    Historically, identity researchers have placed greater emphasis on processes of identity development (how people develop their identities) and less on the content of identity (what the identity is). The relative neglect of identity content may reflect the lack of a comprehensive framework to guide research. In this article, we provide such a comprehensive framework for the study of the content of identity, including 4 levels of analysis. At the broadest level, we situate individual identity within historical, cultural, and political contexts, elaborating on identity development within the context of shifting cultural norms, values, and attitudes. Histories of prejudice and discrimination are relevant in shaping intersections among historically marginalized identities. Second, we examine social roles as unique and central contexts for identity development, such that relationship labels become integrated into a larger identity constellation. Third, domains of individual or personal identity content intersect to yield a sense of self in which various aspects are subjectively experienced as an integrated whole. We explore the negotiation of culturally marginalized and dominant identity labels, as well as idiosyncratic aspects of identities based on unique characteristics or group memberships. Finally, we argue that the content of identity is enacted at the level of everyday interactions, the "micro-level" of identity. The concepts of identity conflict, coherence, and compartmentalization are presented as strategies used to navigate identity content across these 4 levels. This framework serves as an organizing tool for the current literature, as well as for designing future studies on the identity development.

    The classical symptom specificity hypothesis (Blatt, 1974) particularly associates obsessional symptoms to interpersonal behavior directed at autonomy and separation from others. Cross-sectional group research, however, has yielded inconsistent findings on this predicted association, and a previous empirical case study (Cornelis et al., in press; see Chapter 2) documented obsessional pathology to be rooted in profound ambivalences between autonomous and dependent interpersonal dynamics. Therefore, in the present empirical case study, concrete operationalizations of the classical symptom specificity hypothesis are contrasted to alternative hypotheses based on the observed complexities in Chapter 2. Dynamic associations between obsessional symptoms and interpersonal functioning is further explored, aiming at further contribution to theory building (i.e., through suggestions for potential hypothesis-refinement; Stiles, 2009). Similar to the first empirical case study (Chapter 1), Consensual Qualitative Research for Case studies is used to quantitatively and qualitatively describe the longitudinal, clinical interplay between obsessional symptoms and interpersonal dynamics throughout the process of supportive-expressive psychodynamic therapy. In line with findings from Chapter 1, findings reveal close associations between obsessions and interpersonal dynamics, and therapist interventions focusing on interpersonal conflicts are documented as related to interpersonal and symptomatic alterations. Observations predominantly accord to the ambivalence-hypothesis rather than to the classical symptom specificity hypothesis. Yet, meaningful differences are observed in concrete manifestations of interpersonal ambivalences within significant relationships. Findings are again discussed in light of conceptual and methodological considerations; and limitations and future research indications are addressed.

Similar to the first empirical case study (Chapter 1, Consensual Qualitative Research for Case studies is used to quantitatively and qualitatively describe the longitudinal, clinical interplay between obsessional symptoms and interpersonal dynamics throughout the process of supportive-expressive psychodynamic therapy. In line with findings from Chapter 1, findings reveal close associations between obsessions and interpersonal dynamics, and therapist interventions focusing on interpersonal conflicts are documented as related to interpersonal and symptomatic alterations. Observations predominantly accord to the ambivalence-hypothesis rather than to the classical symptom specificity hypothesis. Yet, meaningful differences are observed in concrete manifestations of interpersonal ambivalences within significant relationships. Findings are again discussed in light of conceptual and methodological considerations; and limitations and future research indications are addressed.

    2017-01-01

    Argumentation is considered crucial in numerous disciplines in schools and universities because it constitutes an important proficiency in peoples' daily and professional lives. However, it is unclear whether argumentation is understood and practiced in comparable ways across disciplines. This study consequently examined empirically how students perceive argumentation in science and (first) language lessons. Specifically, we investigated students' beliefs about the relevance of discourse and the role of facts. Data from 3,258 high school students from 85 German secondary schools were analyzed with multigroup multilevel structural equation modeling in order to disentangle whether or not differences in argumentation across disciplines exist and the extent to which variation in students' beliefs can be explained by gender and school track. Results showed that students perceived the role of facts as highly relevant for science lessons, whereas discursive characteristics were considered significantly less important. In turn, discourse played a central role in language lessons, which was believed to require less knowledge of facts. These differences were independent of students' gender. In contrast, school track predicted the differences in beliefs significantly. Our findings lend evidence on the existence of disciplinary school cultures in argumentation that may be the result of differences in teachers' school-track-specific classroom practice and education. Implications in terms of a teacher's role in establishing norms for scientific argumentation as well as the impact of students' beliefs on their learning outcomes are discussed. PMID:28642727

  19. A comparative study of semi-empirical interionic potentials for alkali halides - II

    Khwaja, F.A.; Naqvi, S.H.

    1985-08-01

    A comprehensive study of some semi-empirical interionic potentials is carried out through the calculation of the cohesive energy, relative stability and pressure induced solid-solid phase transformations in alkali halides. The theoretical values of these properties of the alkali halides are obtained using a new set of van der Waals coefficients and zero-point energy in the expression for interionic potential. From the comparison of the present calculations with some previous sophisticated ab-initio quantum-mechanical calculations and other semi-empirical approaches, it is concluded that the present calculations in the simplest central pairwise interaction description with the new values of the van der Waals coefficients and zero-point energy are in better agreement with the experimental data than the previous calculations. It is also concluded that in some cases the better choice of the interionic potential alone in the simplest semi-empirical picture of interaction gives an agreement of the theoretical predictions with the experimental data much superior to the ab-initio quantum mechanical approaches.

    2000-01-01

    As pharmaceutical companies began to advertise prescription drugs directly to consumers as well as to physicians, understanding the impact of benefit and risk information in drug advertising on physicians and consumers has become more critical. This paper reviews previous empirical studies that examined the content of benefit and risk information in drug advertising and its potential effects on physicians' subsequent prescribing behaviors. It also reviews studies that investigated how consumers process information on a drug's efficacy and side effects. Based on the findings of these studies, implications are discussed for effective marketing information development as well as for government regulation.

    2013-10-01

    Full Text Available Since the 1990s several research projects and empirical studies (process and outcome on Jungian Psychotherapy have been conducted mainly in Germany and Switzerland. Prospective, naturalistic outcome studies and retrospective studies using standardized instruments and health insurance data as well as several qualitative studies of aspects of the psychotherapeutic process will be summarized. The studies are diligently designed and the results are well applicable to the conditions of outpatient practice. All the studies show significant improvements not only on the level of symptoms and interpersonal problems, but also on the level of personality structure and in every day life conduct. These improvements remain stable after completion of therapy over a period of up to six years. Several studies show further improvements after the end of therapy, an effect which psychoanalysis has always claimed. Health insurance data show that, after Jungian therapy, patients reduce health care utilization to a level even below the average of the total population. Results of several studies show that Jungian treatment moves patients from a level of severe symptoms to a level where one can speak of psychological health. These significant changes are reached by Jungian therapy with an average of 90 sessions, which makes Jungian psychotherapy an effective and cost-effective method. Process studies support Jungian theories on psychodynamics and elements of change in the therapeutic process. So finally, Jungian psychotherapy has reached the point where it can be called an empirically proven, effective method.

    To analyze the factorial structure of a new instrument to assess the quality of the family context (Etxadi-Gangoiti Scale) in a sample from the Gipuzkoa cohort of the Environment and Childhood (Infancia y Medio Ambiente [INMA]) study. Families in a sample of 433 two-year-old children were assessed in a home visit with subsequent analysis of the factorial structure and psychometric properties of the data. An exploratory factorial analysis (principal axis factoring and varimax rotation) and a confirmatory factorial analysis were carried out; partial confirmation of the original factorial structure of the instrument was obtained, which revealed the following factorial structures. Subscale (1): promotion of cognitive and linguistic development, social skills, psychomotor skills, and pretend play and imitation; subscale (2): promotion of independence and self-esteem, provision of optimal frustration, social and emotional quality of the relationship, and absence of physical punishment; subscale (3): paternal involvement, low exposure to family conflict, low frequency of family conflict, relationship with the extended family, social support, diversity of experiences, low frequency of stressful events, and low parental perception of stress. The structure of the original instrument structure was partially confirmed, which was attributed to the characteristics of the sample. We stress the importance of the variability obtained in the evaluation of the families, as well as of adequate indicators of reliability in such evaluation. The new instrument could be used in public health to identify deficient family contexts and to design preventive interventions focused on parenting skills. Copyright © 2013 SESPAS.

    Maternal stress can prenatally influence offspring phenotypes and there are an increasing number of ecological studies that are bringing to bear biomedical findings to natural systems. This is resulting in a shift from the perspective that maternal stress is unanimously costly, to one in which maternal stress may be beneficial to offspring. However, this adaptive perspective is in its infancy with much progress to still be made in understanding the role of maternal stress in natural systems. Our aim is to emphasize the importance of the ecological and evolutionary context within which adaptive hypotheses of maternal stress can be evaluated. We present five primary research areas where we think future research can make substantial progress: (1) understanding maternal and offspring control mechanisms that modulate exposure between maternal stress and subsequent offspring phenotype response; (2) understanding the dynamic nature of the interaction between mothers and their environment; (3) integrating offspring phenotypic responses and measuring both maternal and offspring fitness outcomes under real-life (either free-living or semi-natural) conditions; (4) empirically testing these fitness outcomes across relevant spatial and temporal environmental contexts (both pre- and post-natal environments); (5) examining the role of maternal stress effects in human-altered environments-i.e., do they limit or enhance fitness. To make progress, it is critical to understand the role of maternal stress in an ecological context and to do that, we must integrate across physiology, behavior, genetics, and evolution. © The Author 2017.

    Displaying multiple levels of data visually has been proposed to address the challenge of limited screen space. Although many previous empirical studies have addressed different aspects of this question, the information visualization research community does not currently have a clearly articulated consensus on how, when, or even if displaying data at multiple levels is effective. To shed more light on this complex topic, we conducted a systematic review of 22 existing multi-level interface studies to extract high-level design guidelines. To facilitate discussion, we cast our analysis findings

    2012-01-01

    Loneliness is often assumed to be an occupational hazard for senior-ranked members of an organization. However, most of what researchers hear about being "lonely at the top" is anecdote. This article provides empirical evidence from three separate studies assessing loneliness in managers and nonmanagers. Across all three studies, loneliness did not differ by managerial status. Managers were no more or less lonely than their nonmanager counterparts. This suggests that factors beyond seniority may be contributing to loneliness in organizational settings. Ideas for future research are discussed.

  11. Empirical research in medical ethics: How conceptual accounts on normative-empirical collaboration may improve research practice

    Science.gov (United States)

    2012-01-01

    Background The methodology of medical ethics during the last few decades has shifted from a predominant use of normative-philosophical analyses to an increasing involvement of empirical methods. The articles which have been published in the course of this so-called 'empirical turn' can be divided into conceptual accounts of empirical-normative collaboration and studies which use socio-empirical methods to investigate ethically relevant issues in concrete social contexts. Discussion A considered reference to normative research questions can be expected from good quality empirical research in medical ethics. However, a significant proportion of empirical studies currently published in medical ethics lacks such linkage between the empirical research and the normative analysis. In the first part of this paper, we will outline two typical shortcomings of empirical studies in medical ethics with regard to a link between normative questions and empirical data: (1) The complete lack of normative analysis, and (2) cryptonormativity and a missing account with regard to the relationship between 'is' and 'ought' statements. Subsequently, two selected concepts of empirical-normative collaboration will be presented and how these concepts may contribute to improve the linkage between normative and empirical aspects of empirical research in medical ethics will be demonstrated. Based on our analysis, as well as our own practical experience with empirical research in medical ethics, we conclude with a sketch of concrete suggestions for the conduct of empirical research in medical ethics. Summary High quality empirical research in medical ethics is in need of a considered reference to normative analysis. In this paper, we demonstrate how conceptual approaches of empirical-normative collaboration can enhance empirical research in medical ethics with regard to the link between empirical research and normative analysis.

  12. A Structural Model of Business Performance: An Empirical Study on Tobacco Farmers

    Directory of Open Access Journals (Sweden)

    Sony Heru Priyanto

    2006-01-01

    The results of the analysis indicate that factors like personal aspects, together with physical, economic and institutional environments, affect farmers’ entrepreneurship. Personal aspects turn out to be the dominant factor that determines entrepreneurship and farm performance. This study also shows that farmers’ entrepreneurship is affected by their management capacity, which, in turn, affects the farmers’ farm performance. While there is no doubt in the adequacy of the model to estimate farm performance, this finding invites further investigation to validate it in other fields and scale of business, such as in small and medium enterprises and other companies. Furthermore, in order to evaluate the goodness of fit of the model in various contexts, further research both in a cross-cultural context and cross-national contexts using this model should be conducted.

    Aniszewski, Wojciech; Zaleski, Stephane; Popinet, Stephane

    2017-11-01

    In this work, we present a detailed example of numerical study of film formation in the context of metal coating. Liquid metal is drawn from a reservoir onto a retracting solid sheet, forming a coating film characterized by phenomena such as longitudinal thickness variation (in 3D) or waves akin to that predicted by Kapitza and Kapitza (visible in two dimensions as well). While the industry standard configuration for Zinc coating is marked by coexistence of medium Capillary number (Ca = 0.03) and film Reynolds number above 1000, we present also parametric studies in order to establish more clearly to what degree does the numerical method influence film regimes obtained in the target configuration. The simulations have been performed using Basilisk, a grid-adapting, strongly optimized code derived from Gerris . Mesh adaptation allows for arbitrary precision in relevant regions such as the contact line or the meniscus, while a coarse grid is applied elsewhere. This adaptation strategy, as the results indicate, is the only realistic approach for numerical method to cover the wide range of necessary scales from the predicted film thickness (hundreds of microns) to the domain size (meters).

  14. Empirical Hamiltonians

    Peggs, S.; Talman, R.

    1987-01-01

    As proton accelerators get larger, and include more magnets, the conventional tracking programs which simulate them run slower. The purpose of this paper is to describe a method, still under development, in which element-by-element tracking around one turn is replaced by a single man, which can be processed far faster. It is assumed for this method that a conventional program exists which can perform faithful tracking in the lattice under study for some hundreds of turns, with all lattice parameters held constant. An empirical map is then generated by comparison with the tracking program. A procedure has been outlined for determining an empirical Hamiltonian, which can represent motion through many nonlinear kicks, by taking data from a conventional tracking program. Though derived by an approximate method this Hamiltonian is analytic in form and can be subjected to further analysis of varying degrees of mathematical rigor. Even though the empirical procedure has only been described in one transverse dimension, there is good reason to hope that it can be extended to include two transverse dimensions, so that it can become a more practical tool in realistic cases

    2014-07-01

    Full Text Available In the context of the present economic crisis, entrepreneurship has re-emerged as a topic of interest both for policy makers worldwide as well as for academic research. A wide range of psychological, economic and sociological factors influencing entrepreneurial activity is presented by the existing literature. The aim of this paper is to identify the economic and institutional factors that influenced entrepreneurial activity both before and during the crisis. Data for 27 countries worldwide from Global Entrepreneurship Monitor, World Bank World Development Indicators and World Bank’s Worldwide Governance Indicators international databases were collected for the years 2007, 2009 and 2012. A three stage empirical research was conducted: a comparative analysis of the distribution of the selected variables for the three years, principal components analysis in order to provide an image of the intensity and direction of the relationship between the variables and to characterize the statistical units and econometric modelling to describe the variation of entrepreneurial activity in relation with its economic and institutional determinants. Contrary to expectations, the research findings show that before the crisis, the variation of entrepreneurial activity is explained by the negative influence of the perceived confidence in the rules of society and during the crisis it is negatively influenced by the perceived government effectiveness. The limitations of the research are also presented.

    Full Text Available In the context of a knowledge and innovative-based society and economy, smart and creative cities are attracting an increasing number of young people, most of them being gifted, very talented students and high-skilled workforce, with multiple competences. These young people are pro-active and they involve themselves on enhancing the progress of the community in which they are living. Many cities are facing a higher rate of brain drain, as a consequence of the quality of life and the low level of wages considering also a reduce level of acceptance and implementation of innovative solutions. In the last decades migration phenomenon had been amplified and there is an increased young people migration from emergent countries to the innovation driven countries, witch assure more financial stability and favourable conditions to contribute to both personal and professional development for its residents. Through an empiric research, we have identified the most important factors which contribute to the amplified migration among youths. We have also highlighted the motivational elements for returning to homeland, when the socio-economic situation is favourable. The paper includes also a set of recommendations that could create a proper framework to attract talented, skilled and creative youth, regardless their origin country.

    Full Text Available We describe an approach to empirically test the use of metaCASE environments to model methods. Both diagrams and matrices have been proposed as a means for presenting the methods. These different paradigms may have their own effects on how easily and well users can model methods. We extend Batra's classification of errors in data modelling to cover metamodelling, and use it to measure the performance of a group of metamodellers using either diagrams or matrices. The tentative results from this pilot study confirm the usefulness of the classification, and show some interesting differences between the paradigms.

    Single case studies are at the origin of both theory development and research in the field of psychoanalysis and psychotherapy. While clinical case studies are the hallmark of psychoanalytic theory and practice, their scientific value has been strongly criticized. To address problems with the subjective bias of retrospective therapist reports and uncontrollability of clinical case studies, systematic approaches to investigate psychotherapy process and outcome at the level of the single case have been developed. Such empirical case studies are also able to bridge the famous gap between academic research and clinical practice as they provide clinically relevant insights into how psychotherapy works. This study presents a review of psychoanalytic empirical case studies published in ISI-ranked journals and maps the characteristics of the study, therapist, patient en therapies that are investigated. Empirical case studies increased in quantity and quality (amount of information and systematization) over time. While future studies could pay more attention to providing contextual information on therapist characteristics and informed consent considerations, the available literature provides a basis to conduct meta-studies of single cases and as such contribute to knowledge aggregation.

    Bolchini, Davide; Garzotto, Franca; Sorce, Fabio

    Does usability of a web-based communication artifact affect brand, i.e., the set of beliefs, emotions, attitudes, or qualities that people mentally associate to the entity behind that artifact? Intuitively, the answer is “yes”: usability is a fundamental aspect of the quality of the experience with a website, and a “good” experience with a “product” or its reifications tends to translate into “good” brand perception. To date, however, the existence of a connection between web usability and brand perception is shown through anecdotic arguments, and is not supported by published systematic research. This paper discusses a study that empirically investigates this correlation in a more rigorous, analytical, and replicable way. Our main contribution is twofold: on the one hand, we provide empirical evidence to the heuristic principle that web usability influences branding, and we do that through four between subjects controlled experiments that involved 120 subjects. On the other hand, we inform the study with a systematic value-oriented approach to the user experience, and thus provide a conceptual framework that can be reused in other experimental settings, either for replicating our study, or for designing similar studies focusing on the correlation of web branding vs. design factors other than usability.

    Full Text Available Research on the interaction between plantation forestry and aquatic environments is essential to develop environmentally compatible and sustainable management further. Given, in Ireland, the generally low levels of atmospheric pollution, its geology and maritime climate, and the unique fauna and flora due to its island history, such studies are important not only in the regional context, but also internationally, as they provide an opportunity to examine the effect of forestry and forest management practices on aquatic systems per se, without the complications of acidification. Here, some of the major findings of forestry and water research in Ireland have been reviewed and compared with those from the UK and elsewhere. Plantation forests do not exacerbate acidification in the south of Ireland (Munster as a whole so that the influence of forestry on water chemistry is far less important than in other parts of the country (such as Wicklow and Mayo. The main forestry influence on streams in Munster is more likely through physical factors, but their nature is unclear. In a few catchments some negative effects are evident, but in many others apparently positive forest effects occur. In this context, smaller scale catchment-level effects appear to be more important in explaining the various relationships between plantation forests and stream ecology than larger scale regional factors. The management of riparian zones, particularly in forested catchments, is of major importance for the structure and functioning of aquatic communities and further work is needed on best management practices. It is suggested that it is unreasonable to base forest management on national Forest-Fisheries guidelines since regions vary too much and the signal from local conditions is too strong. The approach for environmentally benign, scientifically sound forestry management has to be at the catchment scale. Trees in the right places may be beneficial ecologically but

    With the rapid aging of the population and the increased availability of gambling facilities over the past three decades, older adults may gamble more and may be increasingly at risk for problem gambling (PG) or pathological gambling disorder (PGD). To facilitate a better understanding of gambling behavior among older adults that will inform preventive strategies, this article systematically examined empirical studies on issues related to older adults' gambling. This article reviewed 75 empirical studies including data on the distribution and determinants of PG and PGD and the outcomes of gambling. This review used the broad term of "disordered gambling" as a means to explain a continuum of problems caused by PG and PGD. The analyses covered seven topics concerning older adults' gambling behaviors: Participation rates for gambling, prevalence rates of disordered gambling, motivation for initially beginning to gamble, risk and protective factors for disordered gambling, and negative and positive health outcomes from gambling. Based on research gaps identified in the review, this article proposes six recommendations for future studies focusing on well-being of older adults who gamble, research method issues, and taking into account older adults' inspirations and adjustment to the aging process in the 21st century.

    China is one of the major energy-consuming countries, and is under great pressure to promote energy saving and reduce domestic energy consumption. Employees constitute an important target group for energy saving. However, only a few research efforts have been paid to study what drives employee energy saving behavior in organizations. To fill this gap, drawing on norm activation model (NAM), we built a research model to study antecedents of employee electricity saving behavior in organizations. The model was empirically tested using survey data collected from office workers in Beijing, China. Results show that personal norm positively influences employee electricity saving behavior. Organizational electricity saving climate negatively moderates the effect of personal norm on electricity saving behavior. Awareness of consequences, ascription of responsibility, and organizational electricity saving climate positively influence personal norm. Furthermore, awareness of consequences positively influences ascription of responsibility. This paper contributes to the energy saving behavior literature by building a theoretical model of employee electricity saving behavior which is understudied in the current literature. Based on the empirical results, implications on how to promote employee electricity saving are discussed. - Highlights: • We studied employee electricity saving behavior based on norm activation model. • The model was tested using survey data collected from office workers in China. • Personal norm positively influences employee′s electricity saving behavior. • Electricity saving climate negatively moderates personal norm′s effect. • This research enhances our understanding of employee electricity saving behavior

    The main purpose of microarray studies is screening of differentially expressed genes as candidates for further investigation. Because of limited resources in this stage, prioritizing genes are relevant statistical tasks in microarray studies. For effective gene selections, parametric empirical Bayes methods for ranking and selection of genes with largest effect sizes have been proposed (Noma et al., 2010; Biostatistics 11: 281-289). The hierarchical mixture model incorporates the differential and non-differential components and allows information borrowing across differential genes with separation from nuisance, non-differential genes. In this article, we develop empirical Bayes ranking methods via a semiparametric hierarchical mixture model. A nonparametric prior distribution, rather than parametric prior distributions, for effect sizes is specified and estimated using the "smoothing by roughening" approach of Laird and Louis (1991; Computational statistics and data analysis 12: 27-37). We present applications to childhood and infant leukemia clinical studies with microarrays for exploring genes related to prognosis or disease progression. Copyright © 2012 John Wiley & Sons, Ltd.

    In the context of social convoy theory, the purposes of the study were (a) to identify an empirical typology of the social networks evident in older Korean immigrants and (b) to examine its association with self-rated health and depressive symptoms. The sample consisted of 1,092 community-dwelling older Korean immigrants in Florida and New York. Latent class analyses were conducted to identify the optimal social network typology based on 8 indicators of interpersonal relationships and activities. Bivariate and multivariate analyses were conducted to examine how the identified social network typology was associated with self-rating of health and depressive symptoms. Results from the latent class analysis identified 6 clusters as being most optimal, and they were named diverse, unmarried/diverse, married/coresidence, family focused, unmarried/restricted, and restricted. Memberships in the clusters of diverse and married/coresidence were significantly associated with more favorable ratings of health and lower levels of depressive symptoms. Notably, no distinct network solely composed of friends was identified in the present sample of older immigrants; this may reflect the disruptions in social convoys caused by immigration. The findings of this study promote our understanding of the unique patterns of social connectedness in older immigrants. © The Author 2013.

    Full Text Available This study is a systematic review of the field research conducted in medical settings investigating collective learning behaviors. The review was driven by several research foci. Our main interest was in identifying antecedents and consequences of collective learning in hospitals. We also report results on the types of research questions addressed, research designs used, and types of medical teams investigated. Twelve studies met our inclusion criteria. Our findings revealed that highly contextualized studies that use different ways of measuring learning, different ways of conceptualizing medical teams, and different research methodologies, discuss similar antecedents. Variables like leadership behaviors, unit interpersonal climate, and hierarchical position were found to play a role in explaining organizational learning in hospitals across studies. We also found that despite an intense public discourse on the link between collective learning processes and patients’ safety and medical organizations’ performance, few studies actually report empirical data supporting this relationship.

    Full Text Available This article examines the self-reflexion of Slovenian entrepreneurs to their own business activity, with a focus on their core values and virtues, which would consequently affect the performance, growth and development of entrepreneurship in Slovenia. The article starts with a theoretical understanding of organizational values and moral virtues of entrepreneurs and review of the recent empirical studies as the basis on which it is possible to achieve the explanation of the attitude of Slovenian entrepreneurs towards entrepreneurship. We have conducted our own empirical quantitative study on the representative sample of Slovenian entrepreneurs (n =114. Using the obtained results, we tried to verify the six hypotheses. We were particularly interested in those hypotheses that presuppose the entrepreneur who highly appreciates and respects the values and virtues of an ethical businesspearson in practice, will be more economically successful. Based on the results of our research we indicated that the Slovenian entrepreneurs are largely aware of the relevant organizational values and moral virtues, although this is not always obvious in their actions in everyday business practices. The article concludes with an interpretation of the results and discussion of the prospects and challenges for further exploration of the topics covered.

    2015-11-01

    The capability of reproducing the open circuit voltages (V oc) of 15 representative C60 fullerene derivatives was tested using the selected quantum mechanical methods (B3LYP, PM6, and PM7) together with the two one-electron basis sets. Certain theoretical treatments (e.g. PM6) were found to be satisfactory for preliminary estimates of the open circuit voltages (V oc), whereas the use of the B3LYP/6-31G(d) approach has been proven to assure highly accurate results. We also examined the structural similarity of 19 fullerene derivatives by employing principle component analysis (PCA). In order to express the structural features of the studied compounds we used molecular descriptors calculated with semi-empirical (PM6 and PM7) and density functional (B3LYP/6-31G(d)) methods separately. In performing PCA, we noticed that semi-empirical methods (i.e. PM6 and PM7) seem satisfactory for molecules, in which one can distinguish the aromatic and the aliphatic parts in the cyclopropane ring of PCBM (phenyl-C61-buteric acid methyl ester) and they significantly overestimate the energy of the highest occupied molecular orbital (E HOMO). The use of the B3LYP functional, however, is recommended for studying methanofullerenes, which closely resemble the structure of PCBM, and for their modifications.

    The release of smartphones and tablets, which offer more advanced communication and computing capabilities, has led to the strong emergence of mHealth on the market. mHealth systems are being used to improve patients' lives and their health, in addition to facilitating communication between doctors and patients. Researchers are now proposing mHealth applications for many health conditions such as dementia, autism, dysarthria, Parkinson's disease, and so on. Usability becomes a key factor in the adoption of these applications, which are often used by people who have problems when using mobile devices and who have a limited experience of technology. The aim of this paper is to investigate the empirical usability evaluation processes described in a total of 22 selected studies related to mHealth applications by means of a Systematic Literature Review. Our results show that the empirical evaluation methods employed as regards usability could be improved by the adoption of automated mechanisms. The evaluation processes should also be revised to combine more than one method. This paper will help researchers and developers to create more usable applications. Our study demonstrates the importance of adapting health applications to users' need.

    Full Text Available Measuring organization performance plays an important role for developing better strategic plans. In today's competitive environment, organizations attempt for the product quality or offering the service, delivery, reliability capability and the customer satisfaction. These properties are not measurable only by traditional financial criteria and we need a method, which could consider non-financial factors as well. The present study of this paper proposed a hybrid of balanced score card (BSC and data envelopment analysis (DEA method for an empirical study of banking sector. The study proposes a model for assessing the Tose`eTa`avon bank performance, which is an example of governmental credit and financial services institutes. The study determines different important factors associated with each four components of BSC and uses analytical hierarchy process to rank the measures. In each part of BSC implementation, we use DEA for ranking different units of bank and efficient and inefficient units are determined.

    This study investigates the factors predicting positive self-disclosure on social networking sites (SNSs). There is a formidable body of empirical research relating to online self-disclosure, but very few studies have assessed the antecedents of positive self-disclosure. To address this literature gap, the current study tests the effects of self-esteem, life satisfaction, social anxiety, privacy concerns, public self-consciousness (SC), and perceived collectivism on positive self-disclosure on SNSs. Data were collected online via Qualtrics in April 2013. Respondents were undergraduate students from the University of Connecticut. Using ordinary least squares regression, the current study found that self-esteem and perceived collectivism increased positive self-disclosure, life satisfaction, and privacy concerns decreased positive self-disclosure, and the effects of social anxiety and public SC were not significant.

    2009-01-01

    Internationally the stroke unit is recognised as the evidence-based model for patient management, although clarity about the effective components of stroke units is lacking. Whilst skilled nursing care has been proposed as one component, the theoretical and empirical basis for stroke nursing is limited. We attempted to explore the organisational context of stroke unit nursing, to determine those features that staff perceived to be important in facilitating high quality care. A case study approach was used, that included interviews with nurses and members of the multidisciplinary teams in two Canadian acute stroke units. A total of 20 interviews were completed, transcribed and analysed thematically using the Framework Approach. Trustworthiness was established through the review of themes and their interpretation by members of the stroke units. Nine themes that comprised an organisational context that supported the delivery of high quality nursing care in acute stroke units were identified, and provide a framework for organisational development. The study highlighted the importance of an overarching service model to guide the organisation of care and the development of specialist and advanced nursing roles. Whilst multidisciplinary working appears to be a key component of stroke unit nursing, various organisational challenges to its successful implementation were highlighted. In particular the consequence of differences in the therapeutic approach of nurses and therapy staff needs to be explored in greater depth. Successful teamwork appears to depend on opportunities for the development of relationships between team members as much as the use of formal communication systems and structures. A co-ordinated approach to education and training, clinical leadership, a commitment to research, and opportunities for role and practice development also appear to be key organisational features of stroke unit nursing. Recommendations for the development of stroke nursing

    Elkordy, Angela

    The deficit in STEM skills is a matter of concern for national economies and a major focus for educational policy makers. The development of Information and Communications Technologies (ICT) has resulted in a rapidly changing workforce of global scale. In addition, ICT have fostered the growth of digital and mobile technologies which have been the learning context, formal and informal, for a generation of youth. The purpose of this study was to design an intervention based upon a competency-based, digitally-mediated, learning intervention: digital badges for learning STEM habits of mind and practices. Designed purposefully, digital badge learning trajectories and criteria can be flexible tools for scaffolding, measuring, and communicating the acquisition of knowledge, skills, or competencies. One of the most often discussed attributes of digital badges, is the ability of badges to motivate learners. However, the research base to support this claim is in its infancy; there is little empirical evidence. A skills-based digital badge intervention was designed to demonstrate mastery learning in key, age-appropriate, STEM competencies aligned with Next Generation Science Standards (NGSS) and other educational standards. A mixed methods approach was used to study the impact of a digital badge intervention in the sample middle and high school population. Among the findings were statistically significant measures which substantiate that in this student population, the digital badges increased perceived competence and motivated learners to persist at task.

    Full Text Available Cross-border e-commerce has been very successful in the last decade. Merchants and consumers have been encouraged to participate in e-commerce, including B2C or B2B. B2C is not limited to a domestic market anymore. Consumers across countries are interested in overseas direct purchases. They are willing to purchase products from major online shopping sites such as Amazon and eBay. We aim at gaining a better understanding of overseas direct purchases. Determinants of overseas direct purchases based on cross-national data are identified. Accordingly, we investigate logistics and regulatory determinants. Furthermore, external environments such as regulatory institutions and globalization are discussed in terms of overseas direct purchases. This study incorporates theoretical foundations into empirical findings. Specifically, the institutional theory and the resource-based view are applied to explain the internal and external determinants to increase overseas direct purchases. We conduct an empirical test using panel data for each country to identify the various determinants associated with overseas direct purchases.

    Full Text Available This study aims at empirically investigating the drivers of sustainable economic growth in EU-28 countries. By means of panel data regression models, in the form of fixed and random effects models, alongside system generalized method of moments, we examine several drivers of real gross domestic product (GDP growth rate, as follows: higher education, business environment, infrastructure, technology, communications, and media, population lifestyle, and demographic changes. As regards higher education, the empirical results show that expenditure per student in higher education and traditional 18–22 year-old students are positively linked with sustainable economic growth, whereas science and technology graduates negatively influence real GDP growth. In terms of business environment, total expenditure on research and development and employment rates of recent graduates contributes to sustainable development, but corruption perceptions index revealed a negative association with economic growth. As well, the results provide support for a negative influence of infrastructure abreast technological measures on economic growth. Besides, we found a negative connection between old-age dependency ratio and sustainable economic growth.

    Full Text Available Radical and Incremental Innovation Preferences in Information Technology: An Empirical Study in an Emerging Economy Abstract Innovation in information technology is a primary driver for growth in developed economies. Research indicates that countries go through three stages in the adoption of innovation strategies: buying innovation through global trade, incremental innovation from other countries by enhancing efficiency, and, at the most developed stage, radically innovating independently for competitive advantage. The first two stages of innovation maturity depend more on cross-border trade than the third stage. In this paper, we find that IT professionals in in an emerging economy such as India believe in radical innovation over incremental innovation (adaptation as a growth strategy, even though competitive advantage may rest in adaptation. The results of the study report the preference for innovation strategies among IT professionals in India and its implications for other rapidly growing emerging economies.

    Full Text Available This study is aimed at empirically exploring the pertinent factors, which customers and non-customer perceive as germane to their selection of Islamic bank in Aceh, Indonesia. A sample of 300 customers and non-customer of Bank Aceh Syariah were selected based on the convenience sampling technique. Using the logistic regression technique, the study documented that the customers’ selection of the banks were influenced by the factors of banks’ characteristic, services and trust, shari’ah compliance, and physical objects. Of these factors, banks’ characteristic and shari’ah compliance were found to be the most pertinent factors perceived by the customers and non-customer to their selection of Islamic bank in Aceh, Indonesia. These findings imply that to attract more customers, the Islamic bank should enhance their unique characteristics and products’ compliance.DOI:10.15408/aiq.v8i2.3139

    Full Text Available Chaos management is one of the most necessary efforts on managing business units. Many organizations fail to cope with undesirable circumstances, which may happen without any prior notice and as a result, they may face with significant financial losses. In this paper, we present an empirical study to determine critical success factors, which could help handle any possible chaos in organizations. The proposed study of this paper is implemented for a set of travel agencies located in Tehran, Iran. Chronbach alpha is calculated as 0.821, which is well above the minimum desirable level. In addition, we have also performed factor analysis, which yields a KMO value of 0.576 with the level of significance of 0.000. The results indicate that there are six important factors including effective management strategy, internal environmental factors, creative and innovative attitudes, external environmental factors and top level management thoughts.

The existing studies typically assume a distribution or simply build on analogies to communication network routing delay. Specifically, this study provides insight into the characterization of the communication delay of both unprocessed PMU data and synchrophasors sorted by a Phasor Data Concentrator (PDC). The results suggest that a bi-modal distribution containing two normal distributions offers the best fit of the delay of the unprocessed data, whereas the delay profile of the sorted synchrophasors resembles a normal distribution based on these results, the possibility of evaluating the reliability of a synchrophasor application with respect to a particular choice of PDC timeout is discussed.

    Full Text Available The article explores various approaches to the development of cognitive process dimensions in financial literacy. It is based on the empirical research of the financial literacy levels among 1,207 fifteen-year-old Czech students compared with 18 countries worldwide (OECD, 2014a. Applying the regression model, the study has examined the strength of the relationship between the actual financial competence of 284 Czech students aged 17-18, studying economic disciplines, and their school performance. The research has produced the following conclusions: (a a weak dependence of actual skills on school performance; (b inherently associated consequence of school performance is not corresponding to the actual financial skills; (c a low level of financial competence in the dimensions - Remember, Understand and Apply. Proceeding from the research results, it will be desirable to focus on the transfer of economic methods and foreign practice into the learning process, thereby contributing to the improvement of the current situation in Czech Republic.

    Full Text Available Distance education is expanding worldwide. Numbers of students enrolled in distance education are increasing at very high rates. Distance education is said to be the future of education because it addresses educational needs of the new millennium. This paper represents the findings of an empirical study on a sample of Jordanian distance education students into a requirement model that addresses the need of such education at the national level. The responses of the sample show that distance education is offering a viable and satisfactory alternative to those who cannot enroll in regular residential education. The study also shows that the shortcomings of the regular and the current form of distance education in Jordan can be overcome by the use of modern information technology.

    Full Text Available The present study empirically analyzes the factors that determine the adoption of cloud computing (SaaS model in firms where this strategy is considered strategic for executing their activity. A research model has been developed to evaluate the factors that influence the intention of using cloud computing that combines the variables found in the technology acceptance model (TAM with other external variables such as top management support, training, communication, organization size, and technological complexity. Data compiled from 150 companies in Andalusia (Spain are used to test the formulated hypotheses. The results of this study reflect what critical factors should be considered and how they are interrelated. They also show the organizational demands that must be considered by those companies wishing to implement a real management model adopted to the digital economy, especially those related to cloud computing.

    Full Text Available Memes, the replicator of culture and information, and basic unit of culture, are copied, spread, transmitted and finally survives through imitation among vectors. The replication and transmission of memes have some resemblance to the process of second language acquisition. This paper examines the influence of language memes on the development of Chinese college students’ English writing proficiency through an empirical study. The study reveals that students instructed by the framework of teaching writing with memetics obtain an obvious improvement in their overall writing proficiency, compared with those who are instructed by the traditional method, that students’ awareness of using memes is greatly enhanced, and that language memes are significantly correlated to the students’ performance in the post-test writing. Singular language memes can be easily transmitted; memetic genotype prevails in EFL learners’ essay writing.

    1993-01-01

    A study of the bidirectional reflectance distribution function (BRDF) in relation to surface roughness properties was conducted in arid land near Fowlers Gap Research Station, New South Wales, Australia. Such empirical study is necessary for investigating the possibility of determining terrain geomorphological parameters from bidirectional reflectance data. A new apparatus was developed to take accurate hemispherical directions radiance measurements (HDRM). A digitizer for three-dimensional in situ roughness measurements was also developed. More than 70 hemispherical data sets were collected for various illumination conditions and surface types of desert stony pavements and rocky terrain slopes. In general, it was found that most of the surfaces exhibited an anisotropic reflection, combining a major component of backscattering. The BRDF of different surface types in relation to their roughness properties as determined by the field digitizer were then examined. Results showed that sites that are considered to differ significantly from a geomorphological point of view would not necessarily form a different BRDF

    This study examined stabilities of informant and context (home vs. classroom) latent factors regarding anger and attention. Participants included children from the National Institute of Child Health and Development Study of Early Child Care and Youth Development who were measured at 54 months, first grade, and third grade. Latent factors of anger and attention span were structured using different indicators based on mothers', fathers', caregivers', teachers', and observers' reports. We used structural equation modeling to examine the autoregressive effects within a context (stability), the concurrent associations between home and classroom contexts, and informant effects. The results indicated that for both anger and attention (1) there were significant informant effects that influenced stability in a context, (2) there was higher stability in home context than nonhome context, and (3) stability within a context increased over time. The findings suggested that anger was more prone to context effects and informant effects than attention.

    There is a large amount of functional genetic data available, which can be used to inform fine-mapping association studies (in diseases with well-characterised disease pathways). Single nucleotide polymorphism (SNP) prioritization via Bayes factors is attractive because prior information can inform the effect size or the prior probability of causal association. This approach requires the specification of the effect size. If the information needed to estimate a priori the probability density for the effect sizes for causal SNPs in a genomic region isn't consistent or isn't available, then specifying a prior variance for the effect sizes is challenging. We propose both an empirical method to estimate this prior variance, and a coherent approach to using SNP-level functional data, to inform the prior probability of causal association. Through simulation we show that when ranking SNPs by our empirical Bayes factor in a fine-mapping study, the causal SNP rank is generally as high or higher than the rank using Bayes factors with other plausible values of the prior variance. Importantly, we also show that assigning SNP-specific prior probabilities of association based on expert prior functional knowledge of the disease mechanism can lead to improved causal SNPs ranks compared to ranking with identical prior probabilities of association. We demonstrate the use of our methods by applying the methods to the fine mapping of the CASP8 region of chromosome 2 using genotype data from the Collaborative Oncological Gene-Environment Study (COGS) Consortium. The data we analysed included approximately 46,000 breast cancer case and 43,000 healthy control samples. © 2016 The Authors. *Genetic Epidemiology published by Wiley Periodicals, Inc.

  16. The Impact of Job Involvement on Emotional Labor to Customer-Oriented Behavior: An Empirical Study of Hospital Nurses.

    Wang, Mei-Ling; Chang, Shu-Chen

    2016-06-01

    Healthcare is a profession that requires a high level of emotional labor (EL). Nurses provide frontline services in hospitals and thus typically experience high levels of EL. The quality of services that nurses provide impacts on how patients evaluate the service quality of hospitals. The aim of this study is to explore the relationships among EL, job involvement (JI), and customer-oriented behavior (COB) in the context of the nursing profession. The participants in this study were nurses at eight hospitals, all located in Taiwan. This study used a self-reporting questionnaire. Research data were gathered at two discrete periods (A and B). Questionnaire A collected data on EL and JI, and Questionnaire B collected data on COB. Five hundred questionnaires were sent out to qualified participants, and 472 valid questionnaires were returned. Hierarchical regression analysis was used to test the hypotheses. The expression of positive emotion (EPE) and the suppression of negative emotion (SNE) were found to positively affect the patient-oriented COB. Furthermore, the EPE was found to positively affect the task-oriented COB. In terms of the moderating effect of JI, JI was found to relate positively to the EPE, patient-oriented COB, and task-oriented COB. In addition, higher values of JI were found to weaken the relationship between the SNE and the task-oriented COB. It has become an increasingly popular practice for hospital organizations to work to promote the COB of their nursing staffs. The results of this study prove empirically that a relationship exists among EL, COB, and JI in nurses. This study contributes to the related literature, enhances the knowledge of hospital and nursing administrators with regard to EL and COB, and offers a reference for hospital managers who are responsible for designing and executing multidisciplinary programs and for managing hospital-based human resources.

    Full Text Available There are many cases, where we may wish to choose a good accounting system and would like to learn how they work and the advantages and disadvantages of each so we can choose the better one for a business. In this paper, we present an empirical survey to understand whether we can choose accrual or cash accounting system. The proposed study designs a questionnaire among 220 experts in area of accounting affairs. The survey considers four sub hypotheses and one main hypothesis to see whether there are reliable rules and regulations in accrual-based accounting compared with cash accounting or not. Similarly, the survey investigates whether accrual-based accounting is more informative, comprehensive and provides better comparative results compared with cash accounting. The results indicate that accrual-based account performs better in terms of all mentioned criteria and it is a better method for managing accounting affairs compared with cash accounting systems.

    Full Text Available We studied the relationship between investor protection, government behavior, and financial development using data covering six provinces (Guangdong, Jiangsu, Shandong, Zhejiang, Henan, and Sichuan and two provincial-level cities (Beijing and Shanghai in China for the period 2005–2014. Using panel data estimation techniques, we found that there is a positive relationship between investor protection and financial development; by contrast, highly-intense government intervention leads to more financial impediments. Moreover, government intervention in education could promote financial development through its contribution to having a higher amount of the fund supply. Our empirical findings have important implications for policy-makers in terms of reforming the capital market regulation.

    How is new knowledge produced in the natural sciences? This question has long been an issue of central relevance for philosophers, historians and sociologists of science, who have fiercely debated whether and how the emergence of new scientific knowledge can be described as following regular patterns, for example as far as the interplay of theory and experiment is concerned. To this aim, more or less recent historical examples have been used as empirical case studies, and widely diverging conclusions have at times been drawn from the same material. The interdisciplinary, DFG-funded project-cluster "Epistemology of the LHC" (University of Wuppertal, Germany) has in the past three years attempted to investigate knowledge production "in real time" by following the interplay of theory and experiment unfold during the first phase of LHC activity and how the knowledge landscape of high energy physics accordingly did (or did not) change. To try and reconstruct some aspects of this epistemic dynamics, the project ...

    2018-02-01

    Full Text Available Agriculture land use right transfer (ALURT is a new policy designed to meet the demand of the sustainable development of agriculture in China. In the Heihe river basin (HRB, ALURT has also recently been introduced to cope with the emerging challenges in agriculture. In this paper, we empirically study the long-term viability of this new policy in HRB using a sustainability assessment. We collect the documents of ALURT contracts, statistical data of ALURT performance, and conduct interviews with its users. The main finding is that the centralized institutional structure of ALURT in HRB compromises its long-term viability. In particular, the power imbalance under the regulation of the intermediate agency, which causes the dissatisfaction of the participants, is threatening the application of the ALURT policy in the long run. Therefore, we suggest that the role of the intermediate agency in ALURT needs to be redefined, to better serve the sustainable development of agriculture in HRB.

    2016-01-01

    Medicines are an important part of household health spending. A progressive system for financing drugs is thus essential for an equitable health system. Some authors have proposed that the determinants of equity in drug financing are socioeconomic, demographic, and associated with public interventions, but little progress has been made in the empirical evaluation and quantification of their relative importance. The current study estimated quantile regressions at the provincial level in Argentina and found that old age (> 65 years), unemployment, the existence of a public pharmaceutical laboratory, treatment transfers, and a health system orientated to primary care were important predictors of progressive payment schemes. Low income, weak institutions, and insufficient infrastructure and services were associated with the most regressive social responses to health needs, thereby aggravating living conditions and limiting development opportunities.

    A detailed understanding of technological change as an evolutionary process is currently not well understood. To increase our understanding, we build upon theory from organizational ecology to develop a model of endogenous technological growth and determine to what extent the pattern of technological growth can be attributed to the structural or systemic characteristics of the technology itself. Through an empirical investigation of patent data in the biotechnology industry from 1976 to 2003, we find that a technology’s internal (i.e., density and diversity) ecological characteristics have a positive effect on its growth rate. The niche’s external characteristics of crowding and status have a negative effect on its growth rate. Hence, applying theory from organizational ecology increases our understanding of technological change as an evolutionary process. We discuss the implications of our findings for the study of technological growth and evolution, and suggest avenues for further research. PMID:28081570

    Full Text Available The explosion of Internet usage has drawn the attention of researchers towards online Social Networks Marketing (SNM. Research has shown that a number of the Internet users are distrustful and indecisive, when it comes to the use of social networks marketing system. Therefore, there is a need for researchers to identify some of the factors that determine users’ acceptance of social networks marketing using Technology Acceptance Model (TAM. This study extended the Technology Acceptance Model theoretical framework to predict consumer acceptance of social networks marketing within Western Cape Province of South Africa. The research model was tested using data collected from 470 questionnaires and analysed using linear regression. The results showed that user intentions to use SNM are strongly and positively correlated with user acceptance of using SNM systems. Empirical results confirmed that perceived credibility and perceived usefulness are the strongest determinant in predicting user intentions to use SNM system.

    Full Text Available Intellectual capital (IC is normally used to create value for organizations and in today's business environment; the success of each organization depends on managing such assets. During the past few years, many organizations implement IC to increase their competitive advantages. Hospitals are among business units where IC plays an important role on the success of these units. People normally choose hospitals based not only based on their equipments but also based on the specialists and physicians they have. In this paper, we present an empirical study to measure the impact of IC in accounting parts of hospitals. The results of our regression analysis indicates that when there is a unit increase in either of human, customer, structural or intellectual capital individually, we can expect of an increase of 1.278, 1.210, 1.415 and 1.620 units increase in the performance of the university, respectively.

    Full Text Available The majority of research into full-sized helicopter overlapping propulsion systems involves co-axial setups (fully overlapped. Partially overlapping rotor setups (tandem, multirotor have received less attention, and empirical data produced over the years is limited. The increase in demand for compact small unmanned aircraft has exposed the need for empirical investigations of overlapping propulsion systems at a small scale (Reynolds Number < 250,000. Rotor-to-rotor interference at the static state in various overlapping propulsion system configurations was empirically measured using off the shelf T-Motor 16 inch × 5.4 inch rotors. A purpose-built test rig was manufactured allowing various overlapping rotor configurations to be tested. First, single rotor data was gathered, then performance measurements were taken at different thrust and tip speeds on a range of overlap configurations. The studies were conducted in a system torque balance mode. Overlapping rotor performance was compared to an isolated dual rotor propulsion system revealing interference factors which were compared to the momentum theory. Tests revealed that in the co-axial torque-balanced propulsion system the upper rotor outperforms the lower rotor at axial separation ratios between 0.05 and 0.85. Additionally, in the same region, thrust sharing between the two rotors changed by 21%; the upper rotor produced more thrust than the lower rotor at all times. Peak performance was recorded as a 22% efficiency loss when the axial separation ratio was greater than 0.25. The performance of a co-axial torque-balanced system reached a 27% efficiency loss when the axial separation ratio was equal to 0.05. The co-axial system swirl recovery effect was recorded to have a 4% efficiency gain in the axial separation ratio region between 0.05 and 0.85. The smallest efficiency loss (3% was recorded when the rotor separation ratio was between 0.95 and 1 (axial separation ratio was kept at 0

    A wide variety of peer worker roles is being introduced into mental health services internationally. Empirical insight into whether conditions supporting role introduction are common across organisational contexts is lacking. A qualitative, comparative case study compared the introduction of peer workers employed in the statutory sector, voluntary sector and in organisational partnerships. We found good practice across contexts in structural issues including recruitment and training, but differences in expectations of the peer worker role in different organisational cultures. Issues of professionalism and practice boundaries were important everywhere but could be understood very differently, sometimes eroding the distinctiveness of the role.

    Context: Several fracture prediction models that combine fractures at different sites into a composite outcome are in current use. However, to the extent individual fracture sites have differing risk factor profiles, model discrimination is impaired. Objective: The objective of the study was to improve model discrimination by developing a 5-year composite fracture prediction model for fracture sites that display similar risk profiles. Design: This was a prospective, observational cohort study. Setting: The study was conducted at primary care practices in 10 countries. Patients: Women aged 55 years or older participated in the study. Intervention: Self-administered questionnaires collected data on patient characteristics, fracture risk factors, and previous fractures. Main Outcome Measure: The main outcome is time to first clinical fracture of hip, pelvis, upper leg, clavicle, or spine, each of which exhibits a strong association with advanced age. Results: Of four composite fracture models considered, model discrimination (c index) is highest for an age-related fracture model (c index of 0.75, 47 066 women), and lowest for Fracture Risk Assessment Tool (FRAX) major fracture and a 10-site model (c indices of 0.67 and 0.65). The unadjusted increase in fracture risk for an additional 10 years of age ranges from 80% to 180% for the individual bones in the age-associated model. Five other fracture sites not considered for the age-associated model (upper arm/shoulder, rib, wrist, lower leg, and ankle) have age associations for an additional 10 years of age from a 10% decrease to a 60% increase. Conclusions: After examining results for 10 different bone fracture sites, advanced age appeared the single best possibility for uniting several different sites, resulting in an empirically based composite fracture risk model.

    The International Human Reliability Analysis (HRA) Empirical Study is a comparative benchmark of the prediction of HRA methods to the performance of nuclear power plant crews in a control room simulator. There are a number of unique aspects to the present study that distinguish it from previous HRA benchmarks, most notably the emphasis on a method-to-data comparison instead of a method-to-method comparison. This paper reviews seven lessons learned about HRA benchmarking from conducting the study: (1) the dual purposes of the study afforded by joining another HRA study; (2) the importance of comparing not only quantitative but also qualitative aspects of HRA; (3) consideration of both negative and positive drivers on crew performance; (4) a relatively large sample size of crews; (5) the use of multiple methods and scenarios to provide a well-rounded view of HRA performance; (6) the importance of clearly defined human failure events; and (7) the use of a common comparison language to 'translate' the results of different HRA methods. These seven lessons learned highlight how the present study can serve as a useful template for future benchmarking studies.

    Full Text Available Studies of nonhuman primates have reported face sensitive patches in the ventral anterior temporal lobes (ATL. In humans, ATL resection or damage causes an associative prosopagnosia in which face perception is intact but face memory is compromised. Some fMRI studies have extended these findings using famous and familiar faces. However, it is unclear whether these regions in the human ATL are in locations comparable to those reported in non-human primates, typically using unfamiliar faces. We present the results of two studies of person memory: a meta-analysis of existing fMRI studies and an empirical fMRI study using optimized imaging parameters. Both studies showed left-lateralized ATL activations to familiar individuals while novel faces activated the right ATL. Activations to famous faces were quite ventral, similar to what has been reported in monkeys. These findings suggest that face memory-sensitive patches in the human ATL are in the ventral/polar ATL.

    Full Text Available In accordance with the importance that the student stakeholder represents to universities, the objective of this research project was to identify and classify the leading expectations of students at public universities. In order to achieve this, the study adopted both the premises of Stakeholder Theory and the approaches of earlier studies on the management of university stakeholders. This empirical study began with an exploratory study of students, at one university, to identify their expectations this resulting in a list of a total of twenty-five confirmed expectations. This provided the basis for the subsequent quantitative study involving students attending eleven Portuguese public universities. Through recourse to an online questionnaire, we obtained 1,669 correctly completed surveys that provided the input for data analysis deploying descriptive statistical processes and multiple linear regressions. Our findings show that the most important student expectations are the academic level of demand, the university’s connections with the employment market, student personal self-fulfillment and the prevailing university environment. According to students, these expectations should gain priority attention by university managers, once they consider them the most relevant aspects to the relationship between the student and the university.

    This study investigated context-dependent episodic memory retrieval. An influential idea in the memory literature is that performance benefits when the retrieval context overlaps with the original encoding context. However, such memory facilitation may not be driven by the encoding-retrieval overlap per se but by the presence of diagnostic features in the reinstated context that discriminate the target episode from competing episodes. To test this prediction, the encoding-retrieval overlap and the diagnostic value of the context were manipulated in a novel associative recognition memory task. Participants were asked to memorize word pairs presented together with diagnostic (unique) and nondiagnostic (shared) background scenes. At test, participants recognized the word pairs in the presence and absence of the previously encoded contexts. Behavioral data show facilitated memory performance in the presence of the original context but, importantly, only when the context was diagnostic of the target episode. The electrophysiological data reveal an early anterior ERP encoding-retrieval overlap effect that tracks the cost associated with having nondiagnostic contexts present at retrieval, that is, shared by multiple previous episodes, and a later posterior encoding-retrieval overlap effect that reflects facilitated access to the target episode during retrieval in diagnostic contexts. Taken together, our results underscore the importance of the diagnostic value of the context and suggest that context-dependent episodic memory effects are multiple determined.

    2017-11-21

    A novel fuzzy-based approach which combines ELECTRE III along with the Importance-Performance Analysis (IPA) is proposed in the present work to comparatively evaluate the service quality in the public healthcare context. Specifically, ELECTRE III is firstly considered to compare the service performance of examined hospitals in a noncompensatory manner. Afterwards, IPA is employed to support the service quality management to point out improvement needs and their priorities. The proposed approach also incorporates features of the Fuzzy Set Theory so as to address the possible uncertainty, subjectivity and vagueness of involved experts in evaluating the service quality. The model is applied to five major Sicilian public hospitals, and strengths and criticalities of the delivered service are finally highlighted and discussed. Although several approaches combining multi-criteria methods have already been proposed in the literature to evaluate the service performance in the healthcare field, to the best of the authors' knowledge the present work represents the first attempt at comparing service performance of alternatives in a noncompensatory manner in the investigated context.

    Obtaining voluntary informed consent for research participation is an ethical imperative, yet there appears to be little consensus regarding what constitutes a voluntary consent decision. An instrument to assess influences on participants' consent decision and perceived voluntariness was developed and piloted in two South African HIV clinical trials. The pilot study found high levels of perceived voluntariness. The feeling of having no choice but to participate was significantly associated with lower perceived voluntariness. Overall the data suggest that it is possible to obtain voluntary and valid consent for research participants in ethically complex HIV clinical trials in a developing country context.

    Full Text Available To survive in the current competitive, unpredictable business environment, it is significant for firms to search and enforce capabilities that lead them to adapt and cope with dynamic changes of environment for their sustainability. We try to connect operation issues with sustainability in this paper. From the perspective of the dynamic capabilities of the firm, this study suggests a conceptual model that presents relationships among supply chain visibility, modular design, supply chain flexibility, and agility. We do not focus on the module buyer but on the small and middle-sized enterprises (SMEs. An empirical study is performed to verify the relationships proposed, using datasets collected from 232 manufacturing SMEs as module suppliers in South Korea. We used SPSS to analyze data and structural equation modeling to verify the hypotheses of the research model. The important contributions of this study are as follows. Firstly, we suggest relationships among supply chain visibilities and a modular design for supply chain flexibility and agility in sustainable performance. Secondly, we show that supply chain visibility directly leads firms to implement modular design in sustainable development. Thirdly, we verify the importance of supply chain visibility, not for module buyers, but for module suppliers by switching views in terms of SMEs’ sustainability. Lastly, this study shows that the suppliers’ modular design affects supply chain flexibility and agility, which is consistent with the findings presented in the literature.

    Full Text Available Previously, we proposed a model of student reasoning which combines the roles of representation, analogy, and layering of meaning—analogical scaffolding [Podolefsky and Finkelstein, Phys. Rev. ST Phys. Educ. Res. 3, 010109 (2007]. The present empirical studies build on this model to examine its utility and demonstrate the vital intertwining of representation, analogy, and conceptual learning in physics. In two studies of student reasoning using analogy, we show that representations couple to students’ existing prior knowledge and also lead to the dynamic formation of new knowledge. Students presented with abstract, concrete, or blended (both abstract and concrete representations produced markedly different response patterns. In the first study, using analogies to scaffold understanding of electromagnetic (EM waves, students in the blend group were more likely to reason productively about EM waves than students in the abstract group by as much as a factor of 3 (73% vs 24% correct, p=0.002. In the second study, examining representation use within one domain (sound waves, the blend group was more likely to reason productively about sound waves than the abstract group by as much as a factor of 2 (48% vs 23% correct, p=0.002. Using the analogical scaffolding model we examine when and why students succeed and fail to use analogies and interpret representations appropriately.

    Full Text Available Leadership plays an important role among five main components of management. These days, many organizations try to resolve any existing conflicts through adapting an appropriate leadership strategy. During the past few years, there are increasing interests in examining the relationship between management style and conflict management. The proposed study of this paper performs an empirical study to find the relationship between relationship-oriented leadership style and solution-oriented strategy as well as between leadership style and conflict management. The proposed study distributed a questionnaire among 43 managers who were in different industries in west part of Iran. Most of the people who participated in our survey were male and they were between 25 to 30 years old. The study considers relationship between leadership style and conflict management, which includes the relationship between relationship-oriented and task-oriented leaderships with avoiding conflict management strategy, solution and control based conflict managements. The results confirmed that there is only a meaningful relationship between relationship-oriented leadership with solution-based conflict management. In other words, our survey indicates that when there is a conflict, management can handle the problem using his/her relationship and find appropriate solution to resolve any possible conflict.

    2008-11-01

    Concepts of patient competence (PC) are being increasingly used, but seldom clearly defined in the context of shared medical treatment decision making and coping with cancer. The meaning of such concepts should therefore be clarified, and measures developed that permit the assessment of different facets of this patient characteristic. Consequently, this study attempted to contribute to the definition and measurement of PC. Employing literature reviews and qualitative interviews, we developed a working definition of PC in the context of cancer from which we designed a self-rating measure of this patient characteristic that was then tested for validity and reliability in a sample of N=536 patients with cancer. Using factor analyses, we developed five problem- and three emotion-focused subscales that measure distinct facets of PC with satisfactory reliability. Additional analyses provide preliminary evidence of the instruments' validity. This study represents an essential first step in developing a reliable self-rating measure of PC in the context of cancer. Although further refinement of this measure is clearly required, it provides a preliminary methodological basis for empirically investigating the determinants and potential health effects of PC.

    Context-based chemistry education aims at making connections between real life and the scientific content of chemistry courses. The purpose of this study was to evaluate context-based chemistry studies. In looking for the context-based chemistry studies, the authors entered the keywords `context-based', `contextual learning' and `chemistry education' in well-known databases (i.e. Academic Search Complete, Education Research Complete, ERIC, Springer LINK Contemporary). Further, in case the computer search by key words may have missed a rather substantial part of the important literature in the area, the authors also conducted a hand search of the related journals. To present a detailed thematic review of context-based chemistry studies, a matrix was used to summarize the findings by focusing on insights derived from the related studies. The matrix incorporates the following themes: needs, aims, methodologies, general knowledge claims, and implications for teaching and learning, implications for curriculum development and suggestions for future research. The general knowledge claims investigated in this paper were: (a) positive effects of the context-based chemistry studies; (b) caveats, both are examined in terms of students' attitudes and students' understanding/cognition. Implications were investigated for practice in context- based chemistry studies, for future research in context- based chemistry studies, and for curriculum developers in context- based chemistry studies. Teachers of context-based courses claimed that the application of the context-based learning approach in chemistry education improved students' motivation and interest in the subject. This seems to have generated an increase in the number of the students who wish to continue chemistry education at higher levels. However, despite the fact that the majority of the studies have reported advantages of context-based chemistry studies, some of them have also referred to pitfalls, i.e. dominant

    With economy’s continuous rapid growth, textile industry is required to search for new rules and adjust strategies in order to optimize industrial structure and rationalize social spending. The sustainable development of China’s textile industry is a comprehensive research subject. This study analyzed the status of China’s textile industry and constructed the evaluation model based on the economical, ecologic, and social benefits. Analytic Hierarchy Process (AHP) and Data Envelopment Analysis (DEA) were used for an empirical study of textile industry. The result of evaluation model suggested that the status of the textile industry has become the major problems in the sustainable development of China’s textile industry. It’s nearly impossible to integrate into the global economy if no measures are taken. The enterprises concerned with the textile industry status should be reformed in terms of product design, raw material selection, technological reform, technological progress, and management, in accordance with the ideas and requirements of sustainable development. The results of this study are benefit for 1) discover the main elements restricting the industry’s sustainable development; 2) seek for corresponding solutions for policy formulation and implementation of textile industry; 3) provide references for enterprises’ development transformation in strategic deployment, fund allocation, and personnel assignment.

    2014-10-01

    This study introduces a comprehensive model to explain patients' prosocial behavioral intentions to participate in clinical training. Using the helping decision model, the authors analyze the combined impact of factors that affect participation intentions. The model includes intrapersonal and interpersonal appraisals triggered by an awareness of the societal need for clinical training as a practical part of medical education. The results of our empirical study (N=317) show that personal costs and anxiety as negative appraisals and a warm glow as a positive appraisal affect participation intentions and fully mediate the effect of the patient's awareness of the societal need. The study results indicate that communication strategies should address patient beliefs about negative personal consequences of participation rather than highlighting the societal need for practical medical education related to clinical training. Based on the results, medical associations could develop guidelines and provide training for physicians on how to motivate patients to participate in clinical training, resulting in more patient-centered standardized consent discussions.

    The data overload has created a new set of challenges in finding meaningful and relevant information with minimal cognitive effort. However designing robust and scalable knowledge discovery systems remains a challenge. Recent innovations in the (biological) literature mining tools have opened new avenues to understand the confluence of various diseases, genes, risk factors as well as biological processes in bridging the gaps between the massive amounts of scientific data and harvesting useful knowledge. In this paper, we highlight some of the findings using a text analytics tool, called ARIANA--Adaptive Robust and Integrative Analysis for finding Novel Associations. Empirical study using ARIANA reveals knowledge discovery instances that illustrate the efficacy of such tool. For example, ARIANA can capture the connection between the drug hexamethonium and pulmonary inflammation and fibrosis that caused the tragic death of a healthy volunteer in a 2001 John Hopkins asthma study, even though the abstract of the study was not part of the semantic model. An integrated system, such as ARIANA, could assist the human expert in exploratory literature search by bringing forward hidden associations, promoting data reuse and knowledge discovery as well as stimulating interdisciplinary projects by connecting information across the disciplines.

    Full Text Available The retail store can be the key success factor, the competitive advantage of a retail company. An important element to the retail strategy is the store image; the total sum of customers’ perceptions about a store. The present paper compares the theoretical and empirical dimensions of retail store’s image in a Brazilian study. The type of research used was the quantitative study, and the data collected was analyzed by use of the factor analysis technique, in order to identify the underlying factors to retail store image. In conclusion, it was observed that the form by which the respondents evaluate the image of a specific supermarket in Brazil is simpler than what was foreseen by theory, with nine factors representing the following store image dimensions: quality,price, after sales service, advertising, clientele, assortment, convenience, atmosphere and services. An important practical contribution of the present study refers to the development of a simpler scale, that can be used by retailers in a viable form to obtain data on their perceived image.

    Reliably estimated source time functions (STFs) from high-frequency regional waveforms, such as Lg, Pn and Pg, provide important input for seismic source studies, explosion detection and discrimination, and minimization of parameter trade-off in attenuation studies. We have searched for candidate pairs of larger and small earthquakes in and around China that share the same focal mechanism but significantly differ in magnitudes, so that the empirical Green's function (EGF) method can be applied to study the STFs of the larger events. We conducted about a million deconvolutions using waveforms from 925 earthquakes, and screened the deconvolved traces to exclude those that are from event pairs that involved different mechanisms. Only 2,700 traces passed this screening and could be further analyzed using the EGF method. We have developed a series of codes for speeding up the final EGF analysis by implementing automations and user-graphic interface procedures. The codes have been fully tested with a subset of screened data and we are currently applying them to all the screened data. We will present a large number of deconvolved STFs retrieved using various phases (Lg, Pn, Sn and Pg and coda) with information on any directivities, any possible dependence of pulse durations on the wave types, on scaling relations for the pulse durations and event sizes, and on the estimated source static stress drops.

    Full Text Available Purpose: The performance management system (PMS is a metasystem over all business processes at the strategic and operational level. Effectiveness of the various management systems depends on many factors. One of them is the consistent definition of each system elements. The main purpose of this study is to explore if the performance management systems of the sample companies is consistent and how companies can create such a system. The consistency in this case is based on the homogenous definition of attributes relating to the performance indicator as a basic element of PMS.Methodology: At the beginning, we used an affinity diagram that helped us to clarify and to group various attributes of performance indicators. The main research results we achieved are through empirical study. The empirical study was carried out in a sample of Slovak companies. The criterion for selection was the existence of the certified management systems according to the ISO 9001. Representativeness of the sample companies was confirmed by application of Pearson´s chi-squared test (χ2 - test due to above standards. Findings: Coming from the review of various literature, we defined four groups of attributes relating to the performance indicator: formal attributes, attributes of target value, informational attributes and attributes of evaluation. The whole set contains 21 attributes. The consistency of PMS is based not on maximum or minimum number of attributes, but on the same type of attributes for each performance indicator used in PMS at both the operational and strategic level. The main findings are: companies use various financial and non-financial indicators at strategic or operational level; companies determine various attributes of performance indicator, but most of the performance indicators are otherwise determined; we identified the common attributes for the whole sample of companies. Practical implications: The research results have got an implication for

    The financial crisis has made the stock markets a very turbulent place. Investors have therefore begun searching for stable and profitable investments. Nordic real estate has for decades steadily increased in value and the stocks of real estate companies are said to be less risky than the market. This has led to a view of them being a safe haven for risk adverse investors. Very few empirical studies have been done on how these supposedly safe stocks actually behave in the Nordic countries.

    Strategic Environmental Assessment (SEA) has been seen as a preventive and participatory environmental management tool designed to integrate environmental protection into the decision-making process. However, the debate about SEA performance and effectiveness has increased in recent decades. Two main challenges exist in relation to this issue. The first is identifying the key influencing factors that affect SEA effectiveness, and the second is analyzing the relationship between SEA and these influencing factors. In this study, influencing factors were investigated through questionnaire surveys in the Chinese context, and then a Structural Equation Model (SEM) was developed and tested to identify potential links and causal relationships among factors. The associations between the independent factors were divided into direct and indirect causal associations. The results indicate that the decision-making process and policy context directly affect SEA implementation, while information and data sharing, public participation, expertise and SEA institutions are indirectly related with SEA. The results also suggest that a lack of cooperation between different sectors is an obstacle to the implementation of SEA. These findings could potentially contribute to the future management and implementation of SEA or enhance existing knowledge of SEA. The results show that the proposed model has a degree of feasibility and applicability. - Highlights: • Influencing factors were identified and investigated through questionnaire surveys. • Structural Equation Model (SEM) was developed and tested to identify potential links and causal relationships among factors. • Decision-making process and policy context directly affect SEA implementation. • Lack of cooperation among different sectors is an obstacle to the implementation of SEA. • The proposed model has a degree of feasibility and applicability.

    2013-05-01

    The suitable process parameters for a two-stage turbo air classifier are important for obtaining the ultrafine powder that has a narrow particle-size distribution, however little has been published internationally on the classification process for the two-stage turbo air classifier in series. The influence of the process parameters of a two-stage turbo air classifier in series on classification performance is empirically studied by using aluminum oxide powders as the experimental material. The experimental results show the following: 1) When the rotor cage rotary speed of the first-stage classifier is increased from 2 300 r/min to 2 500 r/min with a constant rotor cage rotary speed of the second-stage classifier, classification precision is increased from 0.64 to 0.67. However, in this case, the final ultrafine powder yield is decreased from 79% to 74%, which means the classification precision and the final ultrafine powder yield can be regulated through adjusting the rotor cage rotary speed of the first-stage classifier. 2) When the rotor cage rotary speed of the second-stage classifier is increased from 2 500 r/min to 3 100 r/min with a constant rotor cage rotary speed of the first-stage classifier, the cut size is decreased from 13.16 μm to 8.76 μm, which means the cut size of the ultrafine powder can be regulated through adjusting the rotor cage rotary speed of the second-stage classifier. 3) When the feeding speed is increased from 35 kg/h to 50 kg/h, the "fish-hook" effect is strengthened, which makes the ultrafine powder yield decrease. 4) To weaken the "fish-hook" effect, the equalization of the two-stage wind speeds or the combination of a high first-stage wind speed with a low second-stage wind speed should be selected. This empirical study provides a criterion of process parameter configurations for a two-stage or multi-stage classifier in series, which offers a theoretical basis for practical production.

    Turner, Rebecca M.; Higgins, Julian P. T.

    2015-01-01

    This paper investigates how inconsistency (as measured by the I2 statistic) among studies in a meta‐analysis may differ, according to the type of outcome data and effect measure. We used hierarchical models to analyse data from 3873 binary, 5132 continuous and 880 mixed outcome meta‐analyses within the Cochrane Database of Systematic Reviews. Predictive distributions for inconsistency expected in future meta‐analyses were obtained, which can inform priors for between‐study variance. Inconsistency estimates were highest on average for binary outcome meta‐analyses of risk differences and continuous outcome meta‐analyses. For a planned binary outcome meta‐analysis in a general research setting, the predictive distribution for inconsistency among log odds ratios had median 22% and 95% CI: 12% to 39%. For a continuous outcome meta‐analysis, the predictive distribution for inconsistency among standardized mean differences had median 40% and 95% CI: 15% to 73%. Levels of inconsistency were similar for binary data measured by log odds ratios and log relative risks. Fitted distributions for inconsistency expected in continuous outcome meta‐analyses using mean differences were almost identical to those using standardized mean differences. The empirical evidence on inconsistency gives guidance on which outcome measures are most likely to be consistent in particular circumstances and facilitates Bayesian meta‐analysis with an informative prior for heterogeneity. © 2015 The Authors.

    Hospital pharmacists need access to high-quality information in order to constantly update their knowledge and improve their skills. In their modern role, they are expected to address three types of challenges: scientific, organizational and administrative, thus having an increased need for adequate information and library services. This study investigates the information-seeking behaviour of public hospital pharmacists providing evidence from Greece that could be used to encourage the development of effective information hospital services and study the links between the information seeking behaviour of hospital pharmacists and their modern scientific and professional role. An empirical research was conducted between January and February 2010 with the development and distribution of a structured questionnaire. The questionnaire was filled in and returned by 88 public hospital pharmacists from a total of 286 working in all Greek public hospitals, providing a response rate of 31%. The hospital pharmacists in Greece are in search of scientific information and, more particularly, pharmaceutical information (e.g., drug indications, storage, dosage and prices). The Internet and the National Organization of Medicines are their main information sources, while the lack of time and organized information are the main obstacles they have to face when seeking information. The modern professional role of hospital pharmacists as invaluable contributors to efficient and safer healthcare services may be further supported through the development of specialized libraries and information services within Greek public hospitals. © 2011 The authors.

  14. Definitions of love in a sample of British women: an empirical study using Q methodology.

    Watts, Simon; Stenner, Paul

    2014-09-01

    Social psychological research has increasingly acknowledged that any pretensions to a singular theory of love should be replaced with a concern about its affirmation and what people actually say and do in love's name. Lee's (1977) love styles research and Sternberg's (1995) theory of love as a story are prime examples. Despite traditional definitions of love in western cultures being dominated by feminine images and tales of gender difference, however, the personal definitions and experiences of women have received comparatively little empirical attention, particularly in recent years and despite some well-documented changes in their cultural circumstances. This study remedies that situation through presentation of a Q methodological study in which a convenience sample of 59 British women were asked to Q sort 54 single-word descriptors of love to define love as they had experienced it. Factor analysis of the resulting Q sorts revealed six distinct definitions of love, interpreted as 'attraction, passion & romance', 'unconditional love', 'sex & fun', 'friendship & spirituality', 'a permanent commitment', and 'separate people, separate lives'. The six definitions are then discussed in terms of their allegiance to traditionally feminine and/or masculine values and as a means of highlighting the changing face of Britain's relational culture. © 2013 The British Psychological Society.

    This paper presents an empirical study that quantifies the effects of an ecological fiscal reform as recently rejected by the Swiss population. The measure aims to encourage employment and, at the same time, to dissuade from an excessive energy use and thereby decrease energy-induced external costs (CO 2 , etc.). The analysis is based on the model SCREEN, a general equilibrium model using the complementarity format for the hybrid description of economy-wide production possibilities where the electricity sector is represented by a bottom-up activity analysis and the other production sectors are characterised by top-down production functions. A dynamic formulation of the activity analysis of technologies allows for the reproduction of endogenous structural change (see Frei, C.W., Haldi, P.-A., Sarlos, G., 2003. Dynamic formulation of a top-down and bottom-up merging energy policy model. Energy Policy 31 (10), 1017-1031.). The labour market is formulated according to the microeconomically founded efficiency wages and calibrated for Switzerland. The study includes the development of a consistent set of top-down, bottom-up and labour data for Switzerland. The collection of bottom-up data on the electricity sector, just before liberalisation, was not easy. The electricity sector characterising data was prepared, based on original statistics about 140 Swiss electricity companies

    Full Text Available In deviated and horizontal drilling, hole-cleaning issues are a common and complex problem. This study explored the effect of various parameters in drilling operations and how they affect the flow rate required for effective cutting transport. Three models, developed following an empirical approach, were employed: Rudi-Shindu’s model, Hopkins’, and Tobenna’s model. Rudi-Shindu’s model needs iteration in the calculation. Firstly, the three models were compared using a sensitivity analysis of drilling parameters affecting cutting transport. The result shows that the models have similar trends but different values for minimum flow velocity. Analysis was conducted to examine the feasibility of using Rudi-Shindu’s, Hopkins’, and Tobenna’s models. The result showed that Hopkins’ model is limited by cutting size and revolution per minute (RPM. The minimum flow rate from Tobenna’s model is affected only by well inclination, drilling fluid weight and drilling fluid rheological property. Meanwhile, Rudi-Shindu’s model is limited by inclinations above 45°. The study showed that the investigated models are not suitable for horizontal wells because they do not include the effect of lateral section.

    Full Text Available Chocolate is one of popular gifts among people in many societies. Packaging of such product plays an important role on marketing this item and the primary question of this survey is to determine the impact of packaging on better introducing a product. The inference statistical tests show that packaging is an important item in selection of chocolate as a gift. Percentage of chocolate is the most important information on packaging and color of packaging is of paramount significance when customers purchase chocolate for individuals with official relationship. In this paper, we present an empirical study to measure the effects of chocolates' packaging on purchasing them. The proposed study of this paper designs a questionnaire and distributes them among different people. The results are analyzed using some non-parametric tests and they are discussed. The preliminary results indicate that the number of purchased packages within a year, cost of purchasing chocolate within a year, type of relationship of recipients of chocolate as gift, gender of recipient of chocolate as gift, age group of recipient of gift, type of store, nationality of chocolate, significance of packaging in various price ranges, type of packaging, insertion of information on package and color of packaging, are important factors influencing people to buy more.

    As global competition intensifies, research and development (R & D) organizations need to enhance their strategic management in order to become goal-directed communities for innovation and allocate their resources consistent with their overall R & D strategy. The world pharmaceutical market has undergone fast, unprecedented, tremendous and complex changes in the last several years. The pharmaceutical industry is today still one of the most inventive, innovative and lucrative of the so-called "high-tech" industries. This industry serves a dual role in modern society. On one hand, it is a growing industry, and its output makes a direct contribution to gross domestic product (GDP). On the other side, drugs, this industry's major output, are an input in the production of good health. The purpose of this study is to evaluate R & D activities of pharmaceutical companies, and also to highlight critical factors which have influential effect on results of these activities. To run this study a valid questionnaire based on literature review and experts' opinion was designed and delivered to 11 pharmaceutical companies. Empirical data show there is not acceptable situations considering of the factors that should be taken in to account by managers including; management commitment, human resource management, information technology and financial management. Furthermore, we concluded some interesting results related to different aspects of R & D management. In conclusion, managers must be aware about their performance in R & D activities, accordingly they will able to take a comprehensive policy in both national and within the company.

    Full Text Available Customer service is crucially important for online shopping platforms (OSPs such as eBay and Taobao. Based on the well-established service quality instruments and the scenario of the specific case on Taobao, this paper focuses on exploring the service quality of an OSP with an aim of revealing customer perceptions of the service quality associated with the provided functions and investigating their impacts on customer loyalty. By an empirical study, this paper finds that the “fulfillment and responsiveness” function is significantly related to the customer loyalty. Further analytical study is conducted to reveal that the optimal service level on the “fulfillment and responsiveness” function for the risk averse OSP uniquely exists. Moreover, the analytical results prove that (i if the customer loyalty is more positively correlated to the service level, it will lead to a larger optimal service level, and (ii the optimal service level is independent of the profit target, the source of uncertainty, and the risk preference of the OSP.

    To perform theory construction and empirical study of the competency model of rural general practitioners. Through literature study, job analysis, interviews, and expert team discussion, the questionnaire of rural general practitioners competency was constructed. A total of 1458 rural general practitioners were surveyed by the questionnaire in 6 central provinces. The common factors were constructed using the principal component method of exploratory factor analysis and confirmatory factor analysis. The influence of the competency characteristics on the working performance was analyzed using regression equation analysis. The Cronbach 's alpha coefficient of the questionnaire was 0.974. The model consisted of 9 dimensions and 59 items. The 9 competency dimensions included basic public health service ability, basic clinical skills, system analysis capability, information management capability, communication and cooperation ability, occupational moral ability, non-medical professional knowledge, personal traits and psychological adaptability. The rate of explained cumulative total variance was 76.855%. The model fitting index were Χ(2)/df 1.88, GFI=0.94, NFI=0.96, NNFI=0.98, PNFI=0.91, RMSEA=0.068, CFI=0.97, IFI=0.97, RFI=0.96, suggesting good model fitting. Regression analysis showed that the competency characteristics had a significant effect on job performance. The rural general practitioners competency model provides reference for rural doctor training, rural order directional cultivation of medical students, and competency performance management of the rural general practitioners.

    2013-01-01

    Direct-to-consumer genetic testing (DTC-GT) has sparked much controversy and undergone dramatic changes in its brief history. Debates over appropriate health policies regarding DTC-GT would benefit from empirical research on its benefits, harms, and limitations. We review the recent literature (2011-present) and summarize findings across (1) content analyses of DTC-GT websites, (2) studies of consumer perspectives and experiences, and (3) surveys of relevant health care providers. Findings suggest that neither the health benefits envisioned by DTC-GT proponents (e.g., significant improvements in positive health behaviors) nor the worst fears expressed by its critics (e.g., catastrophic psychological distress and misunderstanding of test results, undue burden on the health care system) have materialized to date. However, research in this area is in its early stages and possesses numerous key limitations. We note needs for future studies to illuminate the impact of DTC-GT and thereby guide practice and policy regarding this rapidly evolving approach to personal genomics. PMID:24058877

  2. Sustainable noise abatement along motorways in Germany – an empirical study in the municipality Frasdorf (Bavaria

    Directory of Open Access Journals (Sweden)

    Jürgen Breuste

    2014-09-01

    Full Text Available As part of the planned expansion work of the motorway A8 between Rosenheim and Salzburg and the associated legal opportunity to develop new traffic noise protection measures, this study investigated properties of sustainable noise abatement in a community next to the A8. A two-stage empirical survey was conducted integrating a citizen and an expert Delphi survey. The results show that the noise from the motorway heavily affects the quality of life in health, economic and ecological respects. Sustainable noise abatement should take into consideration ecological and social aspects like landscape integration and contribution to local development due to the unique location of the municipality. Enclosed motorway canopies are particularly beneficial to meet these criteria. The costs for sustainable noise abatement measures should be weighted as less important; however, financial costs are crucial for the federal government due to the requirements of the Federal Pollution Control Act. Hence, residents and experts assume that noise barriers as the cheaper noise abatement measures will be implemented. However, the results of the study and the latest developments in the expansion plans suggest that the implementation of enclosed motorway canopies, which go beyond the legal requirements, is feasible through extensive citizen participation and community-specific planning.

    Full Text Available Urban mobility is usually understood as something segmented and restricted to subjects related to traffic engineering and pricing policy, recently linked to environmental problems too. The goal of this article was to reach a systemic vision and understand how urban mobility relates also to social, cultural, historical, economical and healthy aspects. A methodology was used including bibliographic research, interviews with specialists and a cross-sectional analysis of these interviews, in order to analyze the context of urban mobility and present tendencies and paths for a more sustainable approach. The result was that the crisis observed nowadays, caused by the unbridled urban developmentism based on the car-based consumerist culture, and evidenced not only by the critical immobility observed on the cities but also by the protests of society, placing urban mobility on the heart of the discussions. Tendencies and sustainable paths were indicated so that urban mobility is a variable that contributes to the well-being of people, equating opportunities and wealth as well as preserving the planet’s ecosystem. The conclusion is that the scenario presents good perspectives to promote a wide discussion regarding the improvement of the quality of urban mobility, and consistent changes are possible according to the change in people´s awareness.

    To assess hospital differences in empirical antibiotic use, bacterial epidemiology, and antimicrobial susceptibility for common antibiotic regimens among young infants with urinary tract infection (UTI), bacteremia, or bacterial meningitis. We reviewed medical records from infants <90 days old presenting to 8 US children's hospitals with UTI, bacteremia, or meningitis. We used the Pediatric Health Information System database to identify cases and empirical antibiotic use and medical record review to determine infection, pathogen, and antimicrobial susceptibility patterns. We compared hospital-level differences in antimicrobial use, pathogen, infection site, and antimicrobial susceptibility. We identified 470 infants with bacterial infections: 362 (77%) with UTI alone and 108 (23%) with meningitis or bacteremia. Infection type did not differ across hospitals ( P = .85). Empirical antibiotic use varied across hospitals ( P < .01), although antimicrobial susceptibility patterns for common empirical regimens were similar. A third-generation cephalosporin would have empirically treated 90% of all ages, 89% in 7- to 28-day-olds, and 91% in 29- to 89-day-olds. The addition of ampicillin would have improved coverage in only 4 cases of bacteremia and meningitis. Ampicillin plus gentamicin would have treated 95%, 89%, and 97% in these age groups, respectively. Empirical antibiotic use differed across regionally diverse US children's hospitals in infants <90 days old with UTI, bacteremia, or meningitis. Antimicrobial susceptibility to common antibiotic regimens was similar across hospitals, and adding ampicillin to a third-generation cephalosporin minimally improves coverage. Our findings support incorporating empirical antibiotic recommendations into national guidelines for infants with suspected bacterial infection.

    Multiple regression analyses were performed on capital cost data for nuclear and coal-fired power plants in an extension of an earlier study which indicated that nuclear units completed prior to the accident at Three-Mile Island (TMI) have no economy of scale, and that units completed after that event have a weak economy of scale (scaling exponent of about 0.81). The earlier study also indicated that the scaling exponent for coal-fired units is about 0.92, compared with conceptual models which project scaling exponents in a range from about 0.5 to 0.9. Other empirical studies have indicated poor economy of scale, but a large range of cost-size scaling exponents has been reported. In the present study, the results for nuclear units indicate a scaling exponent of about 0.94 but with no economy of scale for large units, that a first unit costs 17% more than a second unit, that a unit in the South costs 20% less than others, that a unit completed after TMI costs 33% more than one completed before TMI, and that costs are increasing at 9.3% per year. In the present study, the results for coal-fired units indicate a scaling exponent of 0.93 but with better scaling economy in the larger units, that a first unit costs 38.5% more, a unit in the South costs 10% less, flue-gas desulfurization units cost 23% more, and that costs are increasing at 4% per year

  11. THE RELATIONSHIP BETWEEN CORPORATE VOLUNTEERING AND CORPORATE SOCIAL RESPONSIBILITY: RESULTS OF AN EMPIRICAL STUDY

    Full Text Available Corporate Volunteering (CV is a phenomenon that emerged in the second half of the 20th century and began to grow and globalize at the beginning of the 21st century. There seems to be a consensus that the recent growth of Corporate Volunteering is related to the development and growing legitimacy of the concept of Corporate Social Responsibility (CSR. Nevertheless, the theoretical discussion on how the two concepts (Corporate Volunteering and Corporate Social Responsibility are related is just beginning, while empirical research on how this relationship operates in corporate practice is still incipient. This paper presents preliminary results of a research on this subject carried out in Uruguay in 2016. This is a statistical study that analyses the relationship between the application of corporate volunteering activities and the incorporation of a CSR approach to the management of companies. The incorporation of both types of practices is measured by a self-assessment questionnaire that includes 81 indicators (using a Likert scale to assess them, which were designed based on ISO 26000 Guidance of Social Responsibility. The questionnaire was administered to 96 companies, using a comparative analysis between those that practice Corporate Volunteering and those which do not. The results obtained allow us to support the hypothesis that the application of Corporate Volunteering is positively associated with the incorporation of CSR when managing the relationship between the company and its employees and also with the community. Moreover, these results contribute to a better understanding on how both concepts are related.

  12. Comparing On-Line to In-Person Course Delivery: An Empirical Study

    Full Text Available Web-based technologies have been used in the classroom for over 15 years, including websites, email, listserves, library reserves, and text books. Among these options, social scientists range widely in their web usage – from simply posting syllabi on-line to delivering a course fully on-line in asynchronous learning networks. Use of web-based technology for instructional purposes is increasing, as is enrollment in distance education courses and on-line course offerings. Many administrators and faculty promote on-line instruction as the solution to managing increased college enrollments, particularly among non-traditional students. However, are the academic outcomes of on-line instruction similar to traditional in-person instruction? Few empirical studies have been done. This is unfortunate. The results of an experiment to evaluate the relative effectiveness of on-line verses an in-person course on sociological research are presented. Unfortunately the on-line participants did much worse than the in-person course.

    Full Text Available This study empirically investigated how small and medium-sized Chinese apparel enterprises (SME formed their strategy as a response to the characteristics of business environment in order to achieve competitive business performance. An environment-strategy-performance model was proposed and tested. Using primary data gathered by a questionnaire survey of the Chinese apparel industry, factor analysis and structural equation modeling (SEM were conducted for measurement and structural model analysis and hypothesis testing. Results show the proposed model met parsimonious statistical criteria. The differences in strategy responses to environment between high- and low-performing firms were striking. Confronting an increasingly turbulent business environment, high performers emphasized differentiation strategy through higher quality, better delivery performance, and greater flexibility than cost reduction. In contrast, low performers prioritized low cost while quality and flexibility were given certain weights. The lack of clear focus on strategies could result in a relatively lower performance. While the process of government-led industrial upgrading continues, forward-looking firms have proactively shifted their strategic focus from solely or mainly cost reduction to a variety of differentiating factors which bring in added value and are less imitable by competitors.

    2015-06-01

    We developed a teaching-led research project to empirically ground methodological reflection about digital ethnography. Drawing on Cordelois' collective ethnographic observation approach, fifteen emerging professionals (from a private general education university and a Police Academy in Bogota) collaborated in a method seminar on digital ethnography. They worked in cross-institutional research teams, each carrying SenseCams for 3 days. Students had a dual role as both participants and observers during self-confrontation interviews. The research design enabled emerging professionals to introspect about what it is to be a member of their institution. The SenseCam provided an additional opportunity for observation as it elicited different reactions in the two institutions. The fact that SenseCams produce sequential accounts of activity as well as its situated nature made apparent the autonomy to study and solve daily issues (e.g. transport, security, commitments) by students from the university, while students in the police academy are more focused on responding to unforeseen activities (e.g. police services, unexpected requests). Finally, our research highlights the relevance of the social dimension of introspection for digital ethnography. How digital data that captures an individual perspective is negotiated in a group becomes a key methodological question.

    2016-01-01

    Bus transport networks are directed complex networks that consist of routes, stations, and passenger flow. In this study, the concept of duplication factor is introduced to analyze the differences between uplinks and downlinks for the bus transport network of Harbin (BTN-H). Further, a new representation model for BTNs is proposed, named as directed-space P. Two empirical characteristics of BTN-H are reported in this paper. First, the cumulative distributions of weighted degree, degree, number of routes that connect to each station, and node weight (peak-hour trips at a station) uniformly follow the exponential law. Meanwhile, the node weight shows positive correlations with the corresponding weighted degree, degree, and number of routes that connect to a station. Second, a new richness parameter of a node is explored by its node weight and the connectivity, weighted connectivity, average shortest path length and efficiency between rich nodes can be fitted by composite exponential functions to demonstrate the rich-club phenomenon.

    Targeted vaccination, whether to minimize the forward transmission of infectious diseases or their clinical impact, is one of the 'holy grails' of modern infectious disease outbreak response, yet it is difficult to achieve in practice due to the challenge of identifying optimal targets in real time. If interruption of disease transmission is the goal, targeting requires knowledge of underlying person-to-person contact networks. Digital communication networks may reflect not only virtual but also physical interactions that could result in disease transmission, but the precise overlap between these cyber and physical networks has never been empirically explored in real-life settings. Here, we study the digital communication activity of more than 500 individuals along with their person-to-person contacts at a 5-min temporal resolution. We then simulate different disease transmission scenarios on the person-to-person physical contact network to determine whether cyber communication networks can be harnessed to advance the goal of targeted vaccination for a disease spreading on the network of physical proximity. We show that individuals selected on the basis of their closeness centrality within cyber networks (what we call 'cyber-directed vaccination') can enhance vaccination campaigns against diseases with short-range (but not full-range) modes of transmission. © 2018 The Author(s).

  17. An Empirical Study on User-oriented Association Analysis of Library Classification Schemes

    2002-12-01

    Full Text Available Library classification schemes are mostly organized based on disciplines with a hierarchical structure. From the user point of view, some highly related yet non-hierarchical classes may not be easy to perceive in these schemes. This paper is to discover hidden associations between classes by analyzing users’ usage of library collections. The proposed approach employs collaborative filtering techniques to discover associated classes based on the circulation patterns of similar users. Many associated classes scattered across different subject hierarchies could be discovered from the circulation patterns of similar users. The obtained association norms between classes were found to be useful in understanding users' subject preferences for a given class. Classification schemes can, therefore, be made more adaptable to changes of users and the uses of different library collections. There are implications for applications in information organization and retrieval as well. For example, catalogers could refer to the ranked associated classes when they perform multi-classification, and users could also browse the associated classes for related subjects in an enhanced OPAC system. In future research, more empirical studies will be needed to validate the findings, and methods for obtaining user-oriented associations can still be improved.[Article content in Chinese

    Full Text Available In this paper, we present an empirical investigation to measure the effects of various factors on operating loss in one of major Iranian banks called Bank Mellat. The proposed study of this paper uses a standard questionnaire and distributes it among 57 people who are mainly in top management levels. The questions are categorized into five groups including events related to the processes and methods, events outside the organization, related events within the organization and business disruptions and system failure. The results of our survey confirm that the loss associated with events related to the processes and methods increases operating risk meaningfully, the loss associated with business disruptions and system failure increases operating risk meaningfully and the loss associated with related events within the organization increases operating risk meaningfully. However, our survey do not confirm that the loss associated with events outside the organization increase operating, risk meaningfully. Finally, the preliminary survey of our analysis shows that there is not enough evidence to believe that the effects of business disruption and internal affairs are significantly different from the other event.

    Full Text Available The relation of the managerial efficiency and leadership styles are analysed in this paper. We conducted an empirical study in a Croatian power supply company (HEP. The dominant leadership style in HEP is consultational, which the organization, according to postulates of this research, brings closer to the top global companies, considering that the tendencies in leadership styles point to the need for a new generation of leaders which will be essentially different from the traditional manager. We have determined that there is a significant interdependence between leadership styles of HEP’s managers (measured using Likert’s method and the degree of management work efficiency (measured using the adjusted Mott’s technique; the closer the leadership style is to System 4, that is participational, the higher the managerial efficiency is. Also, we have found that there is no significant difference between lower and middle management in HEP, concerning the relation between leadership styles and efficiency. This means that both levels get better grades for its efficiency if they belong to a consultational and participational leadership style.

    2015-12-01

    Full Text Available An empirical study in Shanghai was performed to explore consumers’ use willingness and opinions on electric vehicle sharing (EVS to help operators effectively operate and expand the new business model. Through the multinomial logistic regression developed for different groups, the results show that the factors of the main trip mode in daily use, monthly transportation expenditure, driving range of electric vehicles, gender, age, marital status and occupation have significant influences on consumers’ use willingness. In short, the population characteristics of people choosing to use EVS are male, aged between 18 and 30 and usually taking the subway and bus as the daily transportation modes. Otherwise, the factors of the acceptable highest price of EVS, occupation and personal monthly income have significant impacts on the use willingness of people who keep a neutral stance. These people pay more attention to convenience and the economy of EVS. These results reveal that a reasonable price, accurate positioning of target groups, convenient site layout and usage are required for operators to successfully launch a new transportation mode of EVS.

    The phenomenon of "posttraumatic play" (PTP) has received much clinical recognition and little empirical support. The objective of this study was to examine various aspects of PTP in young children exposed to terror events and their relation to posttraumatic stress disorder (PTSD). Individual play sessions, conducted with 29 young Israeli children directly exposed to terrorism (M age = 5.47, SD = 1.34) and 25 matched unexposed children (M age = 5.62, SD = 0.87), were coded using the Children's Play Therapy Instrument-Adaptation for Terror Research (CPTI-ATR; S.E. Chazan & E. Cohen, 2003). Analyses using these ratings showed (a) significant differences between the two groups, (b) significant associations with the caregiver's reports on child's exposure, and (c) significant associations with the caregiver's reports on the child's PTSD symptoms. Play activity ratings of predominant negative affects, frequent acting-out/morbid themes, lowered developmental level, and reduced awareness of the child of him- or herself as a player significantly predicted more PTSD symptoms. PTP which included more coping strategies classified as "overwhelmed reexperiencing" and less "reenactment with soothing" was associated with a higher level of PTSD. Play analysis with the CPTI-ATR may be helpful in identifying PTSD in children and also guide the selection of therapeutic techniques. Copyright © 2010 Michigan Association for Infant Mental Health.

    Environmentalism in China is under transformation from the traditional command and control model to emphasize the advantages of economic tools and encourage the participation of the public. Firms are much more aware of the importance of environmental issues, and some of them have practiced environmental activities beyond compliance. In order to help understand the driving mechanism of proactive corporate environmental behaviors from the firm's perspective, this paper identifies the drivers affecting the proactive environmental management level (EML(p)) based on the institutional theory, and gives an empirical study on the firms based in Changshu city of Jiangsu Province, China. The usable data, collected from the 117 valid respondents in a questionnaire survey, indicates that EML(p) is still moderately low currently. Less than 10% of the samples are practicing all the six categorized types of voluntary environmental activities. The econometric exercise confirms a significantly positive effect of the externally mimetic pressure on EML(p), which may attribute to a higher sensitivity of Chinese companies to the market factors. However, the roles of the general public and industrial associations are not significant, showing the marginal power of selected normative pressures. Regarding internal factors, firms, which view environmental issues as opportunities and often arrange internal environmental training, are more likely to adopt proactive environmental activities. More concerns from the general public like neighborhood communities and mass media shall be addressed to enhance the normative power to improve EML(p) in China from the future perspective.

    Self-quantification (SQ) is a way of working in which, by using tracking tools, people aim to collect, manage, and reflect on personal health data to gain a better understanding of their own body, health behavior, and interaction with the world around them. However, health SQ lacks a formal framework for describing the self-quantifiers' activities and their contextual components or constructs to pursue these health related goals. Establishing such framework is important because it is the first step to operationalize health SQ fully. This may in turn help to achieve the aims of health professionals and researchers who seek to make or study changes in the self-quantifiers' health systematically. The aim of this study was to review studies on health SQ in order to answer the following questions: What are the general features of the work and the particular activities that self-quantifiers perform to achieve their health objectives? What constructs of health SQ have been identified in the scientific literature? How have these studies described such constructs? How would it be possible to model these constructs theoretically to characterize the work of health SQ? A systematic review of peer-reviewed literature was conducted. A total of 26 empirical studies were included. The content of these studies was thematically analyzed using Activity Theory as an organizing framework. The literature provided varying descriptions of health SQ as data-driven and objective-oriented work mediated by SQ tools. From the literature, we identified two types of SQ work: work on data (ie, data management activities) and work with data (ie, health management activities). Using Activity Theory, these activities could be characterized into 6 constructs: users, tracking tools, health objectives, division of work, community or group setting, and SQ plan and rules. We could not find a reference to any single study that accounted for all these activities and constructs of health SQ activity. A

    Full Text Available Background: Global health has stimulated a lot of students and has attracted the interest of many faculties, thereby initiating the establishment of many academic programs on global health research and education. global health education reflects the increasing attention toward social accountability in medical education. Objective: This study aims to identify gaps in the studies on global health education. Design: A critical literature review of empirical studies was conducted using Boolean search techniques. Results: A total of 238 articles, including 16 reviews, were identified. There had been a boom in the numbers of studies on global health education since 2010. Four gaps were summarized. First, 94.6% of all studies on global health education were conducted in North American and European countries, of which 65.6% were carried out in the United States, followed by Canada (14.3% and the United Kingdom (9.2%. Only seven studies (2.9% were conducted in Asian countries, five (2.1% in Oceania, and two (0.8% in South American/Caribbean countries. A total of 154 studies (64.4% were qualitative studies and 64 studies (26.8% were quantitative studies. Second, elective courses and training or programs were the most frequently used approach for global health education. Third, there was a gap in the standardization of global health education. Finally, it was mainly targeted at medical students, residents, and doctors. It had not granted the demands for global health education of all students majoring in medicine-related studies. Conclusions: Global health education would be a potentially influential tool for achieving health equity, reducing health disparities, and also for future professional careers. It is the time to build and expand education in global health, especially among developing countries. Global health education should be integrated into primary medical education. Interdisciplinary approaches and interprofessional collaboration were

    This article investigated the influences of structural breaks on the fractionally integrated time-varying volatility model in the Malaysian stock markets which included the Kuala Lumpur composite index and four major sectoral indices. A fractionally integrated time-varying volatility model combined with sudden changes is developed to study the possibility of structural change in the empirical data sets. Our empirical results showed substantial reduction in fractional differencing parameters after the inclusion of structural change during the Asian financial and currency crises. Moreover, the fractionally integrated model with sudden change in volatility performed better in the estimation and specification evaluations.

    Full Text Available The purpose of this study is to identify, in the context of the economic crisis, the Greek consumers’ attitudes and purchase intentions towards private label brands, particularly towards food private label products. It uses an adapted conceptual framework and tests several hypotheses. Measures were adopted from previous literature. Self-administered questionnaires were developed and distributed to approximately 120 respondents who are residents of Thessaloniki. Six of the seven hypotheses are supported empirically, out of which two are validated partially. Thus, perceived quality, perceived risk, perceived benefits (i.e., price and packaging, trust, perceived economic situation and income level influence purchase intention towards private label products. Based on the findings, several recommendations to the retailers and recommendations for further research are provided.

    The study is an empirical investigation of sickness presenteeism in relation to occupation, irreplaceability, ill health, sickness absenteeism, personal income, and slimmed down organisation. Cross sectional design. Swedish workforce. The study group comprised a stratified subsample of 3801 employed persons working at the time of the survey, interviewed by telephone in conjunction with Statistics Sweden's labour market surveys of August and September 1997. The response rate was 87 per cent. A third of the persons in the total material reported that they had gone to work two or more times during the preceding year despite the feeling that, in the light of their perceived state of health, they should have taken sick leave. The highest presenteeism is largely to be found in the care and welfare and education sectors (nursing and midwifery professionals, registered nurses, nursing home aides, compulsory school teachers and preschool/primary educationalists. All these groups work in sectors that have faced personnel cutbacks during the 1990s). The risk ratio (odds ratio (OR)) for sickness presenteeism in the group that has to re-do work remaining after a period of absence through sickness is 2.29 (95% CI 1.79, 2.93). High proportions of persons with upper back/neck pain and fatigue/slightly depressed are among those with high presenteeism (pwork when sick. The link between difficulties in replacement or finding a stand in and sickness presenteeism is confirmed by study results. The categories with high sickness presenteeism experience symptoms more often than those without presenteeism. The most common combination is low monthly income, high sickness absenteeism and high sickness presenteeism.

    Full Text Available The long years of marketing practices in the Nigerian banking industry has recorded low level standards relative to global standard practice. The effect on the overall industry performance measurable basically in terms of customer satisfaction, customer loyalty and brand equity has been on the negativity. In some cases, banks overall performance level was never assessed based on customer orientation, value and other customer related measures rather on some quick financial indicators. This poor orientation towards marketing has rather become a forgone especially in the banking area of financial services in Nigeria. This study was therefore conducted to examine the changing trend towards embracing marketing philosophy and the extent of the banks’ performance level in response to changing expectations of customers. Theoretical issues relating marketing, customer philosophy, financial marketing, customer loyalty, satisfaction, and brand equity were explored to establish the key performance variables and the existing relationships amongst them. Empirical study was equally carried out with the use of questionnaire, administered on randomly selected banks’ customers and management staff. Data collected were analyzed on the basis of critical measures which include customer awareness, market sensitivity to financial delivery, customer profile and sophistication through the use of Spearman Rank Correlation Coefficient. The result among other things shows that there is a significant relationship between the new trend towards marketing orientation, financial services in the banking industry and performance level. Based on this study, we recommend improved marketing performance and training to enhance service delivery, customer satisfaction, and customer loyalty across all banks in the geographical places of the Nigerian financial markets.

    Full Text Available In this paper, we present an empirical study to detect important factors, which could increase the number of moviegoers. The study distributes a questionnaire among different people at four age groups including 35.2% (men, and 64.8% (women, most of them are single (between 21 to 30 years living at 3- to 4-member families, holding BA degree with 4 to 7 million Rials monthly salary. Inferential statistics tests, including Kolmogorov–Smirnov, binominal or ratio, Chi Square and Friedman, show that type of story, genre and artists, casts are considered as the most important factors in selection of film while quality of sound, seat comfort, ventilation of cinema hall are regarded as the most important factors in selection of cinema. In addition, cinema is not predominant pastime or hobby of individuals during holidays and existence of more attractive pastimes than cinema is the most important factor, which hinders individuals from going to cinema. Individuals go to cinema fewer than three times a year, primarily during the afternoon of holidays at the weekend. TV teasers and word of mouth advertisements are the most significant publicity tools for those individuals who intend to go to cinema halls. These two factors, i.e. TV teasers and word of mouth advertisements, are the most significant sources of studying individuals for the selection of film. Individuals almost select their favorite movies before going to cinema and if ticket is finished at the box office of cinema, they suspend watching film in another time and finally, they re-plan watching film. It should be noted that satisfaction of individuals from cinema is much more effective than their satisfaction from film.

    A meta-analysis of empirical studies performed in Korea was conducted to systematically investigate the associations between the indices of Internet addiction (IA) and psychosocial variables. Systematic literature searches were carried out using the Korean Studies Information Service System, Research Information Sharing Service, Science Direct, Google Scholar, and references in review articles. The key words were Internet addiction, (Internet) game addiction, and pathological, problematic, and excessive Internet use. Only original research papers using Korean samples published from 1999 to 2012 and officially reviewed by peers were included for analysis. Ninety-five studies meeting the inclusion criteria were identified. The magnitude of the overall effect size of the intrapersonal variables associated with internet addiction was significantly higher than that of interpersonal variables. Specifically, IA demonstrated a medium to strong association with "escape from self" and "self-identity" as self-related variables. "Attention problem", "self-control", and "emotional regulation" as control and regulation-relation variables; "addiction and absorption traits" as temperament variables; "anger" and "aggression" as emotion and mood and variables; "negative stress coping" as coping variables were also associated with comparably larger effect sizes. Contrary to our expectation, the magnitude of the correlations between relational ability and quality, parental relationships and family functionality, and IA were found to be small. The strength of the association between IA and the risk and protective factors was found to be higher in younger age groups. The findings highlight a need for closer examination of psychosocial factors, especially intrapersonal variables when assessing high-risk individuals and designing intervention strategies for both general IA and Internet game addiction.

Materials and Methods Systematic literature searches were carried out using the Korean Studies Information Service System, Research Information Sharing Service, Science Direct, Google Scholar, and references in review articles. The key words were Internet addiction, (Internet) game addiction, and pathological, problematic, and excessive Internet use. Only original research papers using Korean samples published from 1999 to 2012 and officially reviewed by peers were included for analysis. Ninety-five studies meeting the inclusion criteria were identified. Results The magnitude of the overall effect size of the intrapersonal variables associated with internet addiction was significantly higher than that of interpersonal variables. Specifically, IA demonstrated a medium to strong association with "escape from self" and "self-identity" as self-related variables. "Attention problem", "self-control", and "emotional regulation" as control and regulation-relation variables; "addiction and absorption traits" as temperament variables; "anger" and "aggression" as emotion and mood and variables; "negative stress coping" as coping variables were also associated with comparably larger effect sizes. Contrary to our expectation, the magnitude of the correlations between relational ability and quality, parental relationships and family functionality, and IA were found to be small. The strength of the association between IA and the risk and protective factors was found to be higher in younger age groups. Conclusion The findings highlight a need for closer examination of psychosocial factors, especially intrapersonal variables when assessing high-risk individuals and designing intervention strategies for both general IA and Internet game addiction.

    In this paper, we present the empirical investigation results on the urban public transport networks (PTNs) and propose a model to understand the results obtained. We investigate some urban public traffic networks in China, which are the urban public traffic networks of Beijing, Guangzhou, Wuhan and etc. The empirical results on the big cities show that the accumulative act-degree distributions of PTNs take neither power function forms, nor exponential function forms, but they are described by a shifted power function, and the accumulative act-degree distributions of PTNs in medium-sized or small cities follow the same law. In the end, we propose a model to show a possible evolutionary mechanism for the emergence of such network. The analytic results obtained from this model are in good agreement with the empirical results.

    Given the salience of the interplay between trust and power relations in organizational settings, this paper examines the perceptions of social power and its effects on trust in supervisors within the context of public hospitals. Following the theoretical background from which the study model is developed, the recent situation of hospitals within Turkish healthcare system is discussed to further elucidate the working conditions of physicians. Sample data were collected employing a structured questionnaire that was distributed to physicians working at seven different public hospitals. The statistical analyses indicate that perceptions of supervisors' social power affect subordinates' trust in supervisors. Although coercive power is found to have the greatest impact on trust in supervisors, the influence of the power base is weak. In addition, the results show that perceptions of social power differ between genders. However, the results do not support any of the hypotheses regarding the relations between trust in supervisors and the examined demographic variables. Copyright © 2014 John Wiley & Sons, Ltd.
