This article explains Internet users’ self-help activities in protecting their privacy online using structural equation modeling. Based on a representative survey of Swiss Internet users, it reveals past experiences with privacy breaches as a strong predictor of current protective behavior. Further, in line with the ‘privacy paradox’ argument, caring about privacy (privacy attitudes) alone does not necessarily result in substantial self-protection. Most strikingly, however, general Internet skills are key in explaining users’ privacy behavior. These skills enable users to reduce risks of privacy loss while obtaining the benefits from online activities that increasingly depend on the revelation of personal data. Consequently, Internet skills are an essential starting point for public policies regarding users’ self-help in privacy protection. 相似文献

Contemporary managers are developing alternative ways to sustain their competitive advantages. Motivation-enhancing features such as high-quality meal service provided by organizations can be thought of as one of these methods. The effect of the perceived quality of meal service provided by organizations on the job performance of employees and the mediating role of organizational identification during this process is studied. Private security-sector employees working in Turkey (N?=?597) are being focused in this study. As a result of analyses (correlation and regression analyses, structural equation model), the authors find that the perceived quality of meal service provided by organizations improves employees’ job performance significantly and organizational identification has a partial mediating role on this association. The findings of this study will be of interest to key stakeholders such as public or private organizations, labor unions and the media. 相似文献

In explicit persuasion, the communicator states explicitly a desire to persuade the consumer. By referring to an attributional approach, social engagement was simultaneously explored as a beneficial communicator attribute, while cause-related marketing (CRM) was addressed as a boundary condition. In an experiment, we varied the persuasion strategy (explicit vs. implicit), the communicator’s prior experience with social engagement (yes vs. no), and the specific marketing strategy (CRM vs. non-charity marketing). As expected, in the non-charity marketing condition, explicit (vs. implicit) persuasion was more effective when the communicator had prior experience in social engagement. In the CRM condition, explicit (vs. implicit) persuasion was less effective when the communicator had prior experience in social engagement; when no prior experience was reported, persuasiveness increased. 相似文献

One of the most prevalent problems in face transplant patients is an inability to generate facial expression of emotions. The purpose of this study was to measure the subjective recognition of patients’ emotional expressions by other people. We examined facial expression of six emotions in two facial transplant patients (patient A = partial, patient B = full) and one healthy control using video clips to evoke emotions. We recorded target subjects’ facial expressions with a video camera while they were watching the clips. These were then shown to a panel of 130 viewers and rated in terms of degree of emotional expressiveness on a 7-point Likert scale. The scores for emotional expressiveness were higher for the healthy control than they were for patients A and B, and these varied as a function of emotion. The most recognizable emotion was happiness. The least recognizable emotions in Patient A were fear, surprise, and anger. The expressions of Patient B scored lower than those of Patient A and the healthy control. The findings show that partial and full-face transplant patients may have difficulties in generating facial expression of emotions even if they can feel those emotions, and different parts of the face seem to play critical roles in different emotional expressions. 相似文献

Human rights (HR), from the perspective of interest and thematic selection, are recognized in the topics of the communication. In general, there is considered to be a positive relationship between the media and its function of mediation with citizenship in reference to the declared general principles since inception in 1948. With this approach, the paper deals with providing an updated reflection of that connection and its main difficulties, such as the crisis of credibility in the information in the context of the European Union and within the framework of the paradigm changes that has derived in the knowledge society of the so-called third environment. The precepts of those recognized as generations of HR survive in the informational stories, of which, due to their current relevance in recent decades, those related to migratory movements, inequality, and poverty stands out. Moreover, the paper explores and discusses how a new generation derived from the implementation and intervention of technology gets involved as an essential characteristic in the relations between the members of society. 相似文献

Food and nutrition insecurity remains a challenge in sub-Saharan Africa. Several studies have examined food and nutrition insecurity in urban or rural areas but have not captured the whole continuum. Between November and December 2013, 240 households were surveyed along the urban–rural continuum in Northern Ghana. The study objective was to understand the socio-spatial dynamics of household food and nutrition insecurity and to investigate the role played by urban, peri-urban and rural agriculture. The study found that there was more involvement in agriculture in rural areas compared to peri-urban areas and urban areas. Households from urban areas were more food insecure (HFIAS >?11) compared to their counterparts in peri-urban and the rural areas. Stunting increased by 3.4 times (p?=?0.048) among households located in the peri-urban area. Wasting was reduced by 0.16 times among household that produced staple food or vegetables (p?=?0.011). Overweight was reduced by 0.04 times among households that produced livestock (p?=?0.031). The results reveal a socio-spatial dimension of food and nutrition insecurity that is related to agricultural activities. 相似文献

The economic as well as political and ideological crises and transformations of capitalist social formations have created a crisis for Marxist approaches. This affects their assumption about the necessity, desirability and possibility of social transformation, but also about the actors fighting them out and their activities. Thus, a far reaching reformulation of its fundamental epistemological and theoretical assumptions is necessary. This contribution argues that the crisis of Marxism demands a self-reflective engagement with conditions of Marxist theoretical work. The acknowledgement of the fundamental openness and incompleteness of Marxist social critique as well as its contested production is indispensable to avoid authoritarian forms of politics and to be implicated into the legitimation of domination again. The encompassing character of the crisis tendencies of capitalist social formations and the multiplication of fields of conflict demands to overcome a monistic interpretation of social dynamics. To conceptualise capitalist social formations as relation of relations is an indispensable precondition for the analysis of the connections between different social structures and relations of power and dominance. Furthermore, the ability of capitalist social formations to change, which has been shown by the recent crises and transformations, demands a fundamental dynamisation of the Marxist concept of reproduction. The dynamisation of relative surplus production in knowledge based capitalism moves the adaptability of the subjects and their capacity to work centre stage. Only against this background can the plurality of perspectives for emancipation and social struggles come into view for Marxist theoretical work. 相似文献

Prior research suggests that congregational characteristics are associated with the racial attitudes of Black churchgoers. This study examines the relationship between congregational diversity and beliefs about the Black/White socioeconomic gap among Black religious adherents. Drawing upon pooled data from the General Social Survey and the National Congregations Study, we fit binary logistic regression models to estimate the association between congregational diversity and the explanations of Black/White economic inequality among Black religious adherents. Findings from our study reveal that congregational diversity is one factor that accounts for intragroup differences in racial attitudes among Black religious affiliates. Relative to Blacks that attend religious services in overwhelmingly Black congregations, Blacks that attend religious services in congregations that are overwhelmingly White are significantly less likely to attribute Black/White socioeconomic gaps to a lack of educational opportunities. Our study demonstrates that congregational diversity is a source of intragroup variation in racial attitudes among Black religious affiliates, which may attenuate the ability of such congregations to bridge racial divisions. 相似文献

The no-wait job shop problem (NWJS-R) considered here is a version of the job shop scheduling problem where, for any two operations of a job, a fixed time lag between their starting times is prescribed. Also, sequence-dependent set-up times between consecutive operations on a machine can be present. The problem consists in finding a schedule that minimizes a general regular objective function. We study the so-called optimal job insertion problem in the NWJS-R and prove that this problem is solvable in polynomial time by a very efficient algorithm, generalizing a result we obtained in the case of a makespan objective. We then propose a large neighborhood local search method for the NWJS-R based on the optimal job insertion algorithm and present extensive numerical results that compare favorably with current benchmarks when available. 相似文献
