The study examines the impact of critical organizational factors (organizational culture and excellent leader performance) on public relations professionals’ overall job satisfaction by focusing on testing the joint mediating effects work engagement and trust could generate. A national online survey of 838 public relations professionals working in a variety of organizations was used as the empirical data to test the relationships in a proposed conceptual model. Results confirmed the strong impact organizational culture and leader performance could have on public relations professionals’ work engagement, trust, and job satisfaction. More importantly, results revealed the significant joint mediating effects of engagement and trust on professionals’ job satisfaction, when supportive organizational culture and excellent leader performance were achieved. The study concludes with research and practical implications.  相似文献

Research on evacuation from natural disasters has been published across the peer‐reviewed literature among several disparate disciplinary outlets and has suggested a wide variety of predictors of evacuation behavior. We conducted a systematic review to summarize and evaluate the current literature on demographic, storm‐related, and psychosocial correlates of natural disaster evacuation behavior. Eighty‐three eligible papers utilizing 83 independent samples were identified. Risk perception was a consistent positive predictor of evacuation, as were several demographic indicators, prior evacuation behavior, and having an evacuation plan. The influence of prior experiences, self‐efficacy, personality, and links between expected and actual behavior were examined less frequently. Prospective, longitudinal designs are relatively uncommon. Although difficult to conduct in postdisaster settings, more prospective, methodologically rigorous studies would bolster inferences. Results synthesize the current body of literature on evacuation behavior and can help inform the design of more effective predisaster evacuation warnings and procedures.  相似文献

Measurement error is often a severe problem in longitudinal data such as labor-market flows. Two correction methods have been used for labor-market flows, but the methods tend to adjust the data in opposite directions. One method shows a rigid labor market with long unemployment spells, whereas the other shows the opposite. Because the methods appear theoretically similar, one might interpret the differing results as an indictment of both procedures. This article documents and explains the differences between the two methods. More important, it argues that the differences result from the reliance of one method on assumptions that are theoretically implausible and rejected by the data.  相似文献

Postmodernism continues to have a detrimental influence on social work, questioning the Enlightenment, criticizing established research methods, and challenging scientific authority. The promotion of postmodernism by editors of Social Work and the Journal of Social Work Education has elevated postmodernism, placing it on a par with theoretically guided and empirically based research. The inclusion of postmodernism in the 2008 Educational Policy and Accreditation Standards of the Council on Social Work Education and its 2015 sequel further erode the knowledge-building capacity of social work educators. In relation to other disciplines that have exploited empirical methods, social work’s stature will continue to ebb until postmodernism is rejected in favor of scientific methods for generating knowledge.  相似文献

Hill stated that “An interesting open problem is to determine which common distributions (or mixtures thereof) satisfy Benford's law …”. This article quantifies compliance with Benford's law for several popular survival distributions. The traditional analysis of Benford's law considers its applicability to datasets. This article switches the emphasis to probability distributions that obey Benford's law.  相似文献

At the time of entry into the U.S., immigrants are required to identify their ’intended’ destination to INS officials. They are not, however, required to remain in that location. If immigrant settlement patterns represent an evolutionary, dynamic system, it is likely that immigrants will adjust their location in the period shortly after arrival in the U.S. in response to various factors, leading to an ‘initial’ settlement system. Of interest in the following paper are the scale, direction and magnitude of adjustments made to the immigrant settlement system in the period shortly after arrival. The analysis utilizes the 1990 5 percent Public Use Microdata Sample (PUMS) and the 1985–90 Immigration and Naturalization Service (INS) Public Use Tapes in order to explore the intended and initial (observed) settlement patterns of recent (1985–90) immigrants and to comment upon the applicability of these terms. Results indicate that the two settlement patterns are highly similar, despite apparently high levels of movement among recent arrivals. The analysis also touches upon the ‘come to stay’ question raised by Ellis and Wright (1998a), suggesting that the interpretation of the question is dependent upon immigrant status rather than when immigrants first arrived in the U.S. This research was funded by a grant from the National Science Foundation (97-08436).

We quantified determinants of international migratory inflows to 17 Western countries and outflows from 13 of these countries between 1950 and 2007 in 77,658 observations from multiple sources using panel-data analysis techniques. To construct a quantitative model that could be useful for demographic projection, we analyzed the logarithm of the number of migrants (inflows and outflows separately) as dependent variables in relation to demographic, geographic, and social independent variables. The independent variables most influential on log inflows were demographic [log population of origin and destination and log infant mortality rate (IMR) of origin and destination] and geographic (log distance between capitals and log land area of the destination). Social and historical determinants were less influential. For log outflows from the 13 countries, the most influential independent variables were log population of origin and destination, log IMR of destination, and log distance between capitals. A young age structure in the destination was associated with lower inflows while a young age structure in the origin was associated with higher inflows. Urbanization in destination and origin increased international migration. IMR affected inflows and outflows significantly but oppositely. Being landlocked, having a common border, having the same official language, sharing a minority language, and colonial links also had statistically significant but quantitatively smaller effects on international migration. Comparisons of models with different assumed correlation structures of residuals indicated that independence was the best assumption, supporting the use of ordinary-least-squares estimation techniques to obtain point estimates of coefficients.  相似文献

Increasingly, partnerships and other cooperative forms of governance are common-place in addressing problems of environmental management in rural landscapes. These forms of governance are multi-dimensional in the policy instruments employed; the make-up of actors; and, the types of rationalities that actors use to debate the problem and proposed solutions. This paper pursues the question of how different modes of social action, represented in argumentative claims of participants, influence social coordination in these governance arenas. An empirical study is presented of agri-environmental governance in Australia where actors debate planning and policy initiatives to reduce diffuse water quality impacts from farms on the adjacent Great Barrier Reef. Forester’s conceptualisation of practical social action which locates communicative action in the ‘real world’ of interest-based planning contexts, is used as an analytical frame to identify: (i) the type of claims made by governments, farmer groups and other actors in argumentation; (ii) the claims association with communicative, strategic and instrumental modes of action; and, (iii) their consequence for social coordination in formation and maintenance of inclusive, legitimate and viable forms of governing. The study finds that the interconnected character of claims made by actors, and the ready switching between modes of action observed, point to a situated and dynamic expression of rationality within these contested and prolonged debates on how to legitimately and effectively govern rural environments.  相似文献

Taylor’s law states that the variance of the distribution of distance between two randomly chosen individuals is a power function of the mean distance. It applies to the distances between two randomly chosen points in various geometric shapes, subject to a few conditions. In Réunion Island and metropolitan France, at some spatial scales, the empirical frequency distributions of inter-individual distances are predicted accurately by the theoretical frequency distributions of inter-point distances in models of geometric probability under a uniform distribution of points. When these models fail to predict the empirical frequency distributions of inter-individual distances, they provide baselines against which to highlight the spatial distribution of population concentrations.  相似文献
