The objective of this study is to determine the level of job satisfaction experienced by social workers and to establish whether there are significant differences between the various levels of job satisfaction and a series of personal features and job characteristics. The participants were 947 social workers (861 women and 86 men) belonging to 35 of the 36 Professional Associations existing in Spain. The measurement tool used is the Job Satisfaction Survey scale, designed by Spector [2002. Psicología Industrial y Organizacional: Investigación y Práctica [Industrial and organizational psychology: Research and practice]. México: Manual Moderno]. The results show that the social workers surveyed experience moderate levels of job satisfaction (M?=?115.8; SD?=?21.4). The intrinsic factor that seems to have the greatest positive influence on job satisfaction is the nature of the job, while the extrinsic factors of pay, fringe benefits, and operating conditions are the ones that contribute most to job dissatisfaction, and social workers have no control over any of them.  相似文献

This article aims to examine several interrelated issues pertaining to the historical development of pluralism in areas forming today´s Malaysia. Firstly, it intends to analyze the transformation of the formerly cosmopolitan populations of Malay port polities into the highly ‘racialized’ society of modern Malaysia. It also seeks to clarify the roots of ethnicity-based issues and relations in the country. Lastly, it attempts to challenge the very concept of Malaysia as a society primarily consisting of three ethnic pillars, dominated by the Malays, and ‘complemented’ by the Chinese and the Indians. I argue that the main driving force behind these tensions is the segregational colonial policies and the postcolonial arrangements of the Malay ethnocentrist governments, rather than ethnic and cultural factors as the ruling politicians tend to stress. I also contend that religious issues, especially those stemming from the dakwah movement, are gradually becoming an increasingly important factor in interrace strife.  相似文献

ABSTRACT

The topic of informatization and digitization of social work is a new phenomenon bringing new challenges that need to be dealt with. However, in the Czech Republic, the processes of informatization, digitization and e-social work may still look like grey zones. This article presents the result of one of the first Czech studies whose aim was to find out how social workers interpret the impacts of the use of information and communication technologies on social work. The goal of the research was to find out how the ongoing process of informatization permeates the Czech social work aimed at the target group of vulnerable children and their families. The authors have applied a qualitative research strategy in this research project using semi-structured interviews as the technique of data collection. The utilization of this technique has enabled them to obtain information from 25 social workers. The interviews have been analysed using the procedures of situational analysis. When interpreting the results, the authors focused on the area of communication where information and communication technologies are used, which social workers considered crucial.  相似文献

How do CEOs react to attainment discrepancies in their organizations' performance? Scholars have generally argued that (only) when performance falls below a certain aspiration level do CEOs intend to change the organization's strategy. However, empirical evidence on this issue is ambiguous and inconclusive. We address this puzzle directly by studying how CEOs' cognitive interpretations of performance (their satisfaction with the firm's performance) affect the magnitude of intended strategic changes, and we explore the moderating effect of the context (performance compared to the industry) on this relationship. Using a sample of medium-sized organizations, we find that CEOs' satisfaction with performance is negatively related to intended strategic changes, as expected, but only in contexts of poor performance compared to the industry. The negative relationship becomes less pronounced when performance compared to the industry reaches a certain threshold and even appears to reverse when the latter is extremely high. Moreover, exploratory post hoc analyses tentatively suggest the existence of two alternative intended change trajectories: contractive as a reaction to dissatisfaction and poor performance, and expansive as a response to satisfaction and high performance. These findings help to contextualize the effects of attainment discrepancies in light of conventional performance feedback theory and alternative theoretical perspectives.  相似文献

We examine firms' propensity to adapt their R&D collaboration portfolio by establishing new types of R&D collaboration with different kinds of partners (suppliers, customers, competitors and universities & public research institutions). We argue that existing R&D collaboration with one of the two value chain partners (suppliers or customers) is associated with the formation of new R&D collaboration with the other value chain partner to ensure temporal alignment in innovation within the value chain. In contrast, issues related to governance and unintended knowledge spillovers suggest that ‘horizontal’ R&D collaboration with competitors only spurs R&D collaboration with other partner types if such competitor R&D collaboration has been discontinued earlier (‘delayed temporal alignment’). We posit that persistent prior R&D collaboration with institutional partners is an antecedent to the establishment of new R&D collaboration with industrial partners, and that discontinuation of a particular type of R&D collaboration is likely to lead to a restart of such R&D collaborative effort. Strong prior innovative performance is expected to increase the probability that firms establish R&D collaborations with new partner types, except for R&D collaboration with competitors, since the most innovative firms may fear leakage of proprietary knowledge to rivals. We find broad support for these predictions in a large panel of Spanish innovating firms (2004–2011). Our findings highlight that it is not just the configuration of R&D collaborations with existing partner types that predicts tie formation with new partner types, but also the intertemporal pattern of prior R&D collaboration and managerial discretion provided by past innovation success.  相似文献

The vertex arboricity va(G) of a graph G is the minimum number of colors the vertices can be colored so that each color class induces a forest. It was known that \(va(G)\le 3\) for every planar graph G. In this paper, we prove that \(va(G)\le 2\) if G is a planar graph without intersecting 5-cycles.  相似文献

An extensive literature provides evidence that conflict between employees’ family and work duties is associated with stress and poor well-being, which have negative consequences for firms and their employees. This paper analyzes the role of two internal and two external drivers that encourage (or discourage) organizations to adopt and implement work–life balance policies. The role of external financial assistance and specific laws (external drivers), together with budgetary provision for work–life balance policies and managers’ perceptions regarding problems due to work–life conflict (internal drivers), are analyzed. Fuzzy-set qualitative comparative analysis is used to pursue the study’s research goals. Analysis of data on 132 SMEs suggests that financial issues (external financial assistance and/or a specific budget within the company) are key factors for the implementation or lack of implementation of work–life balance policies. Moreover, to implement these policies, managers need not necessarily perceive problems due to work–life conflict. Finally, work–life balance legislation seems not to play an explicit role in the relationships discussed herein. Consequences of these findings are discussed in the final section of the paper.  相似文献

Population ageing, together with the negative effects of the recent economic and financial crisis that some European countries are still facing, have threatened the sustainability of public pension systems. In this context, voluntary private pensions have emerged as the most feasible alternative to supplement the minimum provided by Social Security Systems; however, this financial product does not enjoy its expected popularity. A potential explanation of this reality might be due to the fact that European countries are far from being homogeneous, nor their pensions systems. Therefore, any policy geared toward improving financial retirement planning should take into account these potential differences. As a first approach to their analysis, this paper proposes the existence of four different ‘social models’ in Europe -namely, Continental, Mediterranean, Nordic and Transitional-. Overall, empirical evidence confirmed the significant influence of country’ ‘social model’ on the decision to invest in retirement accounts on a sample of 31,468 individuals in 2013. It was also proved that this decision is positively related to age, household income and wealth, higher levels of formal education, job situation, good health status, and long-term planning horizons; and negatively related to age squared, household size or financial risk aversion. In short, future policies and reforms regarding private pensions should not only take into account the existence of individual differences among Europeans, but also the existence of differences depending on institutional and cultural country factors.  相似文献
