The increase in the Neolithic human population following the development of agriculture has been assumed to result from improvements in health and nutrition. Recent research demonstrates that this assumption is incorrect. With the development of sedentism and the intensification of agriculture, there is an increase in infectious disease and nutritional deficiencies particularly affecting infants and children.Declining health probably increased mortality among infants, children and oldest adults. However, the productive and reproductive core would have been able to respond to this increase in mortality by reducing birth spacing. That is, agricultural populations increased in size, despite higher mortality, because intervals between births became shorter. 相似文献

This research investigated whether biases in processing threatening emotional cues operate as an indirect pathway through which parental harsh discipline is associated with adolescent socio‐emotional functioning. Participants were 192 adolescents (M age = 12.4), and their parents assessed over two years. Findings revealed two significant indirect pathways involving fear processing. Greater parental harsh discipline was linked to more emotional response inhibition difficulty for fear, which was linked to more depressive symptoms in the following year. Greater parental harsh discipline was also associated with more emotional response inhibition difficulty for fear, and thereby, more peer problems later. Findings suggest that adolescent emotional processing operated as an indirect pathway linking parental harsh discipline and adolescent socio‐emotional functioning within the broader social context. 相似文献

Some organizations have begun to target their goal-setting method more closely to the ability levels of their employees. In this article, we report the results of a laboratory study of 138 undergraduate students, which shows that these “ability-based” goals are more effective at improving performance than a “one goal for all” approach, where everyone is assigned the same performance target. Results from repeated measure tests and other analysis of variance tests show that lower-ability individuals in the ability-based goal condition outperform those in the one goal for all condition. Lower- and moderate-ability participants in the one goal for all condition also experienced larger decreases in performance in later rounds. 相似文献

This paper examines the issue of localization or the replacement of expatriates with host country staff following a period of staff development in a developing country, namely Papua New Guinea (PNG). Whilst the use of expatriates appears to be increasing in the PNG private sector, ineffective employer localization programmes remain in PNG. This situation demands operational interventions. The aim of this study was to determine obstacles to localization in private sector organizations in PNG. A total of 114 PNG senior managers responded to a survey designed to determine the factors that were perceived to hinder localization practices. Results suggest that a significant number of managers identify the prevalence of said obstacles, which were categorised into (i) socio-economic circumstances; (ii) recruitment and selection; (iii) local staff performance; (iv) lack of training and development; and (v) compensation. A diagnostic model of localization has also been proposed. The model provides a detailed process for redesigning a localization programme for a developing country. Policy recommendations are also offered for implementation of a more strategic localization programme. 相似文献

Supply chain integration is increasingly seen as a method to obtain flexibility and, consequently, to provide competitive advantage for firms within a supply chain. Product modularity, either in concert with or independent of such integration, can also produce flexibility for firms within a supply chain. In this proof‐of‐concept research, we explore whether the supply chain network affects each constituent firm's market valuation and how decisions regarding the level of supply chain integration and the usage of product modularity are associated with the value of the supply chain. We develop a method to identify and measure the supply chain's effect on each constituent firm's market valuation. Results indicate that greater integration is associated with a higher supply chain valuation, whereas increasing aggregated product modularity across the supply chain relates to a lower supply chain value. However, when combined, the interaction of aggregated product modularity and supply chain integration is positively associated with the supply chain's valuation. 相似文献

In order to determine the prevalence of childhood sexual abuse among gay, lesbian, and bisexual individuals, we conducted a meta-analysis that compiled the results of 65 articles across 9 countries. The results revealed no significant difference in the prevalence of child sexual abuse between homosexual and bisexual people for both sexes. The prevalence of child sexual abuse among female sexual minorities was significantly higher than that among male sexual minorities. The lowest prevalence was found in South America, followed by Asia. The definition of child sexual abuse, dimension used to measure sexual orientation, year of data collection, and the mean age of participants at the time of assessment influenced the estimated prevalence of child sexual abuse. We conclude that many variables influence the reported prevalence of child sexual abuse among sexual minorities. 相似文献

This study investigated victim culpability, credibility, and assault severity in a hypothetical sexual abuse case. A 2 (respondent gender)?×?3 (victim age)?×?3 (perpetrator type) between-subjects design was employed. Members (391) of the U.K. general public read the depiction of a female child assaulted by an adult male perpetrator. Respondents then completed an attributions questionnaire. Findings showed that male respondents were less positive toward victims and considered the victim less credible than female respondents. Younger victims (aged five years) were considered more credible than older children (aged 15 years). Victims of strangers were considered more positively and more credible than victims of someone known to them (their father or a family friend). Suggestions for future work are proposed. 相似文献

SUMMARY When a family member comes out, it is a process not only for that individual lesbian but also for their entire family. Adult daughters whose mothers come out later in life have distinctive paths to navigate. This article reports findings of an interview study with six daughters who were adults when their mothers came out to them. Most daughters felt they emerged from childhood with an open mind about sexual identity, but had no idea about their mother's lesbianism until told by her. Half the participants questioned the role of women in their lives after their mother came out. Five of the six have a very close relationship, or have become closer, with their mother, since her coming out. 相似文献
