Maternal,prenatal and traditional practice factors associated with perinatal mortality in Yemen

Background

Perinatal mortality remains a major international problem responsible for nearly six million stillbirths and neonatal deaths.

论风险社会中过失理论之选择

风险社会中科学技术高速发展,产生了大量的过失犯罪。过失犯罪理论主要包括旧过失论、新过失论、新新过失论。新过失论更契合于风险社会预防犯罪的需要。在责任事故犯罪中,不应放纵监督者的刑事责任,应大力提倡监督过失理论。     

Resilience in parenting among young mothers: Family and ecological risks and opportunities

The present study used a person-centered approach to examine resilience in parenting among a sample of young mothers (under age 21 at childbirth). Resilient functioning as a parent was defined as the lack of perpetration of child maltreatment (substantiated reports of child abuse and neglect) in the context of risk. Risk factors were assessed at multiple levels, including family (e.g., negative childhood histories in family of origin) and ecological (e.g., neighborhood poverty, mother's financial stress) levels. Analyses revealed a group of mothers who demonstrated resilience in parenting despite a context of substantial risks from their childhood histories (e.g., negative family relationships) and current ecologies (e.g., economic and neighborhood conditions). Mothers in the resilient group were less likely to a) live with their families of origin, and b) to rely on their own mothers as sources of emotional or caregiving support. Data also indicated that young mothers' resilient functioning as parents was associated with higher rates of depressive symptoms among these mothers, perhaps suggesting a “cost” or limit to resilient parenting functioning in young mothers. Results are discussed in a resilience framework.     

Communicating risk to parents and those living in areas with a disaster history

This study explored how publics respond to risk communication in high probability but time-indeterminate natural disaster situations when parts of the area have been involved in a similar disaster before. An impending rockslide is expected to produce a tsunami in the fjord around Åknes in Norway. Waves may run up above sea level as high as 82 m or 269 ft. All residents (18 and older) of the four most threatened communities received a questionnaire to determine what they perceived to be useful risk information. Three hundred and eighty-two (43.6% of 875) responded. Results indicated that parents of children living within the tsunami risk zones perceived the risk information to be the most useful. Those who lived in communities that experienced a similar disaster in 1934 reported public meetings less useful than written or mediated information. Publics who lived in communities with such disaster history and those who were not parents posed special challenges in risk communication because they perceived information from the government agencies as lacking in usefulness. Therefore, committing the resources necessary to foster dialogues with a diversity of publics exposed to risk would be well served to fully understand the nature of risk communication responses, and to be able to save human lives.     

Predictors of child protective service contact between birth and age five: An examination of California's 2002 birth cohort

This study utilizes population-level birth data to describe those children who may be at greatest risk of maltreatment during the first five years of life. Based on a unique dataset constructed by linking California's administrative child welfare data to statewide vital birth records, a cohort study design was employed to track reports of maltreatment involving children born in 2002. Twelve variables captured in the birth record were selected for analysis. Generalized Linear Models were used to estimate adjusted risk ratios (RR) for each independent variable. Predicted probabilities of CPS contact were computed based on the count of risk factors present at birth. Results suggest that many of the associations previously observed between birth variables and subsequent maltreatment have sustained value in foretelling which children will be reported to CPS beyond infancy. Of the 531,035 children born in California in 2002, 14% (74,182) were reported for possible maltreatment before the age of five. Eleven of the twelve birth variables examined presented as significant predictors of contact with child protective services.     

Market Impact on IT Security Spending

Traditionally, IT security investment decisions are made in isolation. However, as firms that compete for customers in an industry are closely interlinked, a macro perspective is needed in analyzing these decisions. We utilize the notions of direct‐ and cross‐risk elasticity to describe the customer response to adverse IT security events in the firm and competitor, respectively, thus allowing us to analyze optimal security investment decisions. Examining both symmetric and asymmetric duopoly cases using a continuous‐time Markov chain (CTMC) model, we demonstrate that optimal IT security spending, expected firm profits and willingness of firms to cooperate on security improvements are highly dependent on the nature of customer response to adverse events. We also examine the investment problem when security attacks on different firms are correlated.     

关联方增信与资产证券化信用风险溢价——基于底层资产风险的统计分析

本文着眼于企业资产支持证券(ABS)市场的信用风险溢价,探讨关联方增信的效果。研究表明,采用关联方增信的ABS风险溢价较高;当同一主体先前发行的ABS评级上调时,新发行ABS的风险溢价会因为采用关联方增信而升高。本文进一步探究了产生上述现象的原因,一方面,关联方增信使得集团内部风险集聚;另一方面,企业的道德风险使得原ABS的评级上调成为反映新ABS底层资产质量变差的负面信号,从而影响投资者的定价判断。本研究揭示了关联方增信可能存在的道德风险问题。通过分析ABS丰富的底层资产统计特征,本文发现集团风险集聚导致ABS的底层资产质量下降,进而提高了企业的融资成本。本文建议监管机构可以通过适当限制关联方增信或加强监管的方式保障我国企业资产证券化市场的健康持续发展。     

Conditional payments and self-protection

Self-protection can be financed either by upfront payments or by conditional payments (or contingent fees) in which individuals pay a provider only when a favorable outcome is realized. We find that, from the vantage point of a risk-averse individual, conditional payments welfare dominate upfront payments in the state-independent framework, but upfront payments welfare dominate conditional payments in the state-dependent framework. Moreover, more risk aversion always implies more self-protection under conditional payments, for both state-independent and state-dependent frameworks. In contrast, it has been previously argued that more risk aversion does not necessarily imply more self-protection under upfront payments.

The cluster that never was: germ warfare experiments and health authority reality in Dorset

In 1997 intense media coverage raised public concerns about germ warfare simulation experiments conducted by the Ministry of Defence during the 1960s, which included the release of bacteria over Dorset. Families in East Lulworth, Dorset, have linked this with allegedly high rates of miscarriages, still-births, congenital malformations, learning and other neurodevelopmental disabilities in their village. The response of the Dorset Health Authority (DHA) included the examination of background information from the Ministry of Defence, national data on congenital malformations in Dorset, health information collected by campaigners and a systematic health survey conducted by the DHA among former and current residents of East Lulworth. The investigation did not confirm the presence of a cluster. It is debatable whether the DHA should have proceeded with their survey when none of the other more immediately available results indicated the presence of a cluster.
