The ‘Land of Fires’ is a district in Italy characterized by illegal waste disposal, waste burning, and citizen protests over contamination. This study investigates the relevance of several psycho‐social factors that predict citizens' intention to protest, taking into account different research traditions. In addition, we hypothesize the effect of protest antecedents to be moderated by past participation behaviour (i.e. the level of activism). Hence, our study is a first attempt to explore the effect of protest antecedents as a function of the individual level of activism through a cross‐sectional survey study (N = 306). The results show significant effects of collective identity, sense of injustice, costs of protest, and perceived risk (cognitive dimension) on intention to protest. The effects of collective efficacy and perceived risk (affective dimension) are moderated by participants' level of activism, and these effects are significant only for non‐activists. The relevance of this new approach is discussed, as well as practical implications and possible further developments. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

We exploit the cross-country differences in economic freedom to examine the link between the quality of institutions and subjective well-being. Using Veenhoven’s happiness dataset, the evidence suggests countries with better economic institutions and higher level of economic freedom, captured by the security of property rights, open markets and more limited government, are significantly more likely to experience greater subjective well-being after controlling for structural confounders of national subjective well-being such as income, unemployment, inequality, social capital and life satisfaction. The effect of institutions on cross-national happiness is both significant and robust to different model specifications, estimation techniques and possible sources of endogeneity. Furthermore, our panel data analysis reveals that over time higher levels of economic freedom are associated with decreasing subjective well-being after controlling for state dependence and income.  相似文献

National surveys have shown that mental health problems are prevalent in long-term care and suggest that these settings are largely underserved by mental health services. Nursing home administrators are gatekeepers for mental health services in nursing homes. Administrators of Kentucky nursing homes were surveyed regarding their perceptions of mental health problems, current and future services use, satisfaction with services, and need for consultation. The response rate was 24%. Administrators appeared to underestimate mental health problems among residents. Most facilities were using at least one type of mental health service, but fewer residents received services than would be expected given the problem prevalence. Psychological services were underused, in spite of the fact that behavior management stood out as a major need. Psychiatry was more frequently used, but with less satisfaction. Results indicate significant financial and logistical barriers to mental health services. Future work is needed on developing, assessing, and disseminating models of effective service provision to long-term care.  相似文献

Simple and conditional discrimination training may produce various types of controlling relations. Responses may be controlled primarily by the positive stimulus (select–control relation) or by the negative stimulus (reject–control relation; the subject excludes the negative stimulus and chooses the positive). Bees learn to respond in simple and conditional discriminations. However, no study has searched for reject–control responding in Melipona bees. We trained Melipona quadrifasciata on a simple discrimination task (S+ vs. S‐; e.g., blue vs. yellow) and then probed for stimulus control with two types of probe trials, S+ versus a new stimulus (Select–control probes) and S‐ versus a new stimulus (Reject–control probes). For Group Different, a new‐stimulus color (e.g., white) was used in one type of probe and another color (e.g., black) was used in the other type. For Group Same, a single new‐stimulus color was used in both types of probes. On Select probes, the bees always preferred S+ to the new stimulus. On Reject probes, results were mixed. Depending on the colors used in training and probing, bees responded to both stimuli, and even preferred the S‐. The data suggest no control by the negative function of the S‐ and support the select‐stimulus control hypothesis of responding.  相似文献

Intimate partner violence against women (IPV) and sexual harassment are both widespread. Research on their causes and attitudinal correlates has rarely examined implicit, automatic cognitive associations related to the partner (in IPV aggressors) or to women (in sexual harassment offenders). The aim of the present research was to study these implicit associations in 129 male German students. Participants completed scales of hostile sexism (HS), masculine gender role stress (MGRS), short-term (STMO) and long-term mating orientation (LTMO), and proclivity to both IPV and sexual harassment. Next they performed a primed lexical decision task that measured whether concepts of violence, power, hostility, and sexuality were differentially associated with representations of women, men, and the participant’s own intimate partner. Results showed that implicit associations of own partner with violence as well as hostility were generally high but did not correlate strongly with the proclivity measures. Furthermore, the proclivity measures were positively predicted by HS, MGRS, and STMO, whereas LTMO negatively predicted IPV proclivity. Practice implications point to the need to address early socialization processes that may shape men’s negative associations with female partners. Some strategies to prevent and reduce these types of implicit associations are discussed.

Using evidence‐based guidelines to interview children is an important means to obtain complete and accurate accounts. In the current study, we examined the quality of child investigative interviewing in the Netherlands. To examine this, we compared the Dutch Scenario Model with the National Institute of Child Health and Human Development Protocol and interviews from countries that did not follow a specific protocol. Our principal result was that Dutch child interviewers rarely asked recommended open prompts that are known to elicit detailed and accurate testimonies from children. Furthermore, we found that the scenario model contained the highest number of directive questions compared with interviews from other countries. Our findings show that the Dutch Scenario Model is not well aligned with current research‐based recommendations for interviewing children.  相似文献

Self-recognition is a trait presumed to be associated with high levels of cognition and something previously considered to be exclusive to humans and possibly apes. The most common test of self-recognition is the mark/mirror test of whether an animal can understand that it sees its own reflection in a mirror. The usual design is that an animal is marked with a colour spot somewhere on the body where the spot can only be seen by the animal by using a mirror. Very few species have passed this test, and among birds, only magpies have been affirmatively demonstrated to pass it. In this study, we tested great tits (Parus major), small passerines, that are known for their innovative foraging skills and good problem-solving abilities, in the mirror self-recognition test. We found no indication that they have any ability of this kind and believe that they are unlikely to be capable of this type of self-recognition.  相似文献

In this paper we analyze the non-instrumental dimension of social capital and its effects on subjective well-being. In the first part, we define the characteristics of production and consumption of relational goods. The second section analyses the influence of the different expressions of relational goods and social capital on individual subjective well-being. In the third, we test the explanatory power of this variable on the Easterlin’s paradox using the results of a survey on individual social capital in Spain. The main findings from the empirical analysis for Spanish society allow us to strengthen the hypothesis. We found a weak explanatory capacity of income or educational level or instrumental dimensions of social capital (expert mobilization) while a strong link between expressions of relational goods (domestic mobilization, household stability, partnership, trust and security in the environment) was found.  相似文献

A one-year follow up study was conducted on a sample of 940 Spanish adolescents aged mostly from 10 to 15 in order to explore the extent to which their subjective well-being (SWB) changes from one year to the next, and whether these changes are the same for both genders regardless of the instrument used to measure SWB. Participants responded to the same four SWB scales twice, with an interval of a year in between. A decrease in the levels of SWB is identified from the years 11–12 onwards, the decrease in girls being more marked. Multiple-item, domain-based scales (Brief Multidimensional Student’s Life Satisfaction Scale and Personal Well-Being Index) are more sensitive than single-item scales (Overall Life Satisfaction and Happiness Taking into Account Overall Life) in detecting this decrease. Implications for the study of SWB are discussed from a developmental perspective.  相似文献
