This paper examines the effects of family size and sibling position on children's current school enrollment status in the Philippines. The theoretical framework focuses on the determinants of children's participation in alternative activities, specifically schooling, market work, and home production. This approach allows for a greater understanding of the mechanisms through which fertility, as reflected by number of siblings and sibling composition, influences children's education than would examining the determinants of schooling alone. The model is estimated using the 1983 wave of the Bicol Multipurpose Survey. The results indicate the existence of negative effects of fertility on school enrollment, which, in part, operate through work status. In addition, these effects differ according to the sibling position of the child. 相似文献

We wonder whether tax enforcement varies along the economic cycle and aim at answering that question from a positive perspective by means of survey data for the Spanish case (1994–2015). According to a fiscal capacity argument, tax enforcement might be stronger in times of crisis (counter-cyclical), but if the tax administration prioritizes taxpayers' welfare over public revenue, enforcement might be slacker (procyclical). We find tax enforcement is not immune to the state of the economy. In particular, it presents a prevailing counter-cyclical trend, but in presence of a severe economic crisis it turns out to be procyclical. (JEL D78, H12, H26, H83) 相似文献

The random effects in a gamma process are introduced in terms of its scale parameter. However, the scale parameter affects both its mean and variance. Hence, the variation of the degradation rates and the within degradation increments are expected to be large. For some products, the random effects affect just the rate or just the volatility of the process. Thus, two modifications of the parameters' structure of the gamma process are proposed. One implies that the random effects affect just the volatility and the second just the rate. A Bayesian estimation approach is provided and implemented in two case studies. 相似文献

There are two principal theoretical schools that seek to explain status outcomes in early adulthood: those focusing on intergenerational transmission of class privilege and those emphasizing individual characteristics, particularly ambition. The first may be called the structuralist school and the second the psycho‐social school, following the Wisconsin Model of Status Attainment. A second structuralist perspective, Segmented Assimilation, highlights transmission of socio‐economic status across immigrant generations, but emphasizes the positive role of co‐ethnic resources for upward mobility and preventing downward assimilation. We examine these alternative predictions using a large longitudinal sample of youths in Spain that includes both children of native parentage and children of immigrants. Spain possesses characteristics that make it uniquely suitable to examine these predictions. Results show that both family socio‐economic status and ambition, measured by adolescent educational aspirations and expectations, play important roles in educational and occupational attainment, but the influence of family status persists even after controlling for ambition. The influence of co‐ethnic nationalities disappears after these controls, except among Chinese and Filipino youths, a result consistent with segmented assimilation. Predictive models of status attainment yield identical results for children of immigrants and children of natives, indicating that in Spain, they have become part of a common youth universe. Theoretical and practical implications of the analysis are discussed. 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

This introduction explores reasons for the continuing debate on the subject of transnationalism and persistent scepticism about the significance of the topic. The basis for such disagreements has to do less with the actual existence of the phenomenon than with methodological shortcomings that led to its overestimation in the early literature and the conceptual failure to distinguish between cross‐border activities conducted by major institutions and by private actors in civil society. I explore these various problems seeking to clarify the actual scope of the phenomenon of transnationalism and its novel character. Despite recent findings that point to limited numerical involvement of immigrant groups in transnational activities, the latter remain significant because of their prospective growth and their impact on both immigrant adaptation in receiving countries and the development prospects of sending nations and communities. The evidence presented in the following articles document in detail these various aspects and indicates the multiple forms adopted by this phenomenon among immigrant groups in Europe and the United States. 相似文献

The consumer products generation is one of the main engines that fuel the planet's environmental problems, reduction of environmental impacts associated with the products has been studied from various aspects between them, the supply of products for public consumption instead of private, seeking to meet the needs of the community by establishing programs for sharing single product. It has been detected a problematic issues linked to this strategy, where the user acceptance of this new way of living together with the products must be achieved. The arguments here presented seek to identify user perception of such proposals and their possible acceptance throughout strategies from the User Centered Design (UCD). 相似文献

ABSTRACTTo determine the cerebral functionality associated with the perception and processing of erotic stimuli in men with different sexual orientation, this work evaluated the electroencephalographic activity (EEG) from several cortical areas, as well as subjective arousal in homosexual and heterosexual men during observation of an erotic film with heterosexual content. The heterosexual men rated the erotic video with higher general and sexual arousal than the homosexual participants. During observation of the neutral and erotic videos, both groups showed a decreased amplitude of the alpha band in prefrontal and parietal cortices, indicating increased attention. When watching the erotic video, the homosexual men showed an increased amplitude of the theta and fast bands only in the prefrontal cortex, which could be related to the cognitive processing of the erotic stimulus. These EEG results should broaden our knowledge of the cortical mechanisms related to the different perception and processing of erotic stimuli in men with different sexual orientations. 相似文献

ABSTRACTIn this Notes from the Field, we highlight the work of community based organizations that filled essential gaps in the disaster recovery efforts in Puerto Rico for communities that were heavily damaged by Hurricane Maria yet received little formal government aid. We describe community mobilizing and organizing efforts and identify key lessons for eco-social work practice. As disaster risk increases with climate change, community led efforts are likely to prove vital for the effective protection of the most vulnerable population groups. 相似文献
