网络外部性对双渠道供应链信息分享的影响

研究了网络外部性对双渠道供应链信息分享的影响。分别建立了存在网络外部性和不存在网络外部性下的双渠道供应链模型，通过比较零售商信息分享和不分享下其与制造商的期望利润。研究发现：当未考虑产品的网络外部性时，零售商不与制造商分享其市场需求信息，与已有研究一致。当考虑了产品网络外部性且网络外部性较小时，零售商仍不与制造商分享市场需求信息；然而，当网络外部性较大时，零售商与制造商分享其市场需求信息。此外，零售商与制造商共享其市场需求信息有助于增加制造商和供应链利润。     

Agency and fatalism in older Appalachian women’s information seeking about gynecological cancer

Researchers consider older women in rural Appalachia to have low levels of agency and high levels of fatalism regarding decision making about cancer treatment. Using the life course perspective, we examined older women’s agency with information seeking about gynecological cancer. Semistructured interviews with 20 White women living in central Appalachia revealed four trajectories: Surrendering Control, Accepting Death, Self-Care, and Advocacy, each with its own forms of agency. Some women experienced personal transformation, increased self-efficacy, and a passion for community empowerment. Fatalism was not understood apart from placing trust in medical expertise. We implore researchers to further explore rural expressions of agency.     

Blinded continuous monitoring in clinical trials with recurrent event endpoints

In studies with recurrent event endpoints, misspecified assumptions of event rates or dispersion can lead to underpowered trials or overexposure of patients. Specification of overdispersion is often a particular problem as it is usually not reported in clinical trial publications. Changing event rates over the years have been described for some diseases, adding to the uncertainty in planning. To mitigate the risks of inadequate sample sizes, internal pilot study designs have been proposed with a preference for blinded sample size reestimation procedures, as they generally do not affect the type I error rate and maintain trial integrity. Blinded sample size reestimation procedures are available for trials with recurrent events as endpoints. However, the variance in the reestimated sample size can be considerable in particular with early sample size reviews. Motivated by a randomized controlled trial in paediatric multiple sclerosis, a rare neurological condition in children, we apply the concept of blinded continuous monitoring of information, which is known to reduce the variance in the resulting sample size. Assuming negative binomial distributions for the counts of recurrent relapses, we derive information criteria and propose blinded continuous monitoring procedures. The operating characteristics of these are assessed in Monte Carlo trial simulations demonstrating favourable properties with regard to type I error rate, power, and stopping time, ie, sample size.

构建大数据视阈下的哲学社会科学人才评价机制

哲学社会科学人才评价机制是促进哲学社会科学创新发展的基础性工作。当前，我国哲学社会科学人才评价机制存在着较多的现实困境。信息技术的高速发展为哲学社科人才评价产生了较大的影响，尤其是大数据有助于提升人才评价的科学化和规范化、准确性和预测性、透明性和公平性。构建大数据背景下的哲学社会科学人才评价机制，需要以大数据环境对社会科学人才评价的应用价值为立足点，以多元化的评价主体、客观化的评价标准、公正化的评价程序为基本内容，重点解决好“谁来评”“评什么”“怎么评”的问题。同时，通过完善人才评价法律法规、建立人才资源数据开放共享和一体化平台等措施，努力推动人才评价的法治化、科学化、规范化发展。     

为合法经营活动而侵犯公民个人信息的刑法规制

最高人民法院、最高人民检察院《关于办理侵犯公民个人信息刑事案件适用法律若干问题的解释》第六条对为合法经营活动而侵犯公民个人信息行为进行独立规制,是新型犯罪罪状表述抽象化与罪状解释具体化、信息时代信息价值多元化与危害行为多样化、现代社会犯罪治理精细化与刑法评价精准化的内在要求.为合法经营活动而侵犯公民个人信息行为相关规范要素中的“为合法经营活动”应理解为主观超过要素,“获利五万元”应作严格解释,“曾因侵犯公民个人信息”应作广义解释,“其他情节严重”应包括信息数量标准.     

Conditional covariance penalties for mixed models

The prediction error for mixed models can have a conditional or a marginal perspective depending on the research focus. We introduce a novel conditional version of the optimism theorem for mixed models linking the conditional prediction error to covariance penalties for mixed models. Different possibilities for estimating these conditional covariance penalties are introduced. These are bootstrap methods, cross-validation, and a direct approach called Steinian. The behavior of the different estimation techniques is assessed in a simulation study for the binomial-, the t-, and the gamma distribution and for different kinds of prediction error. Furthermore, the impact of the estimation techniques on the prediction error is discussed based on an application to undernutrition in Zambia.     

Afghan families and health professionals’ access to health information during and after pregnancy

BackgroundHaving a baby in a new country can be challenging, especially if unable to communicate in a preferred language. The aim of this paper is to explore the provision of health information for Afghan women and men during pregnancy, childbirth and the first year after birth in Melbourne, Australia.MethodsCommunity engagement underpinned the study design. Qualitative study with bicultural researchers conducting semi-structured interviews. Interviews and focus groups were also conducted with health professionals.ResultsSixteen Afghan women and 14 Afghan men with a baby aged 4–12 months participated. Thirty four health professionals also participated. Verbal information provided by a health professional with an interpreter was the most common way in which information was exchanged, and was generally viewed favourably by Afghan women and men. Families had limited access to an interpreter during labour and some families reported difficulty accessing an interpreter fluent in their dialect. Availability of translated information was inconsistent and health professionals occasionally used pictures to support explanations. Women and men were unsure of the role of health professionals in providing information about issues other than pregnancy and infant wellbeing.ConclusionBoth individual and health system issues hinder and enable the availability and use of information. Consistent, understandable and ‘actionable’ information is required to meet the needs of diverse families. Health professionals need to be supported with adequate alternatives to written information and access to appropriate interpreters. Inconsistent provision of information is likely to contribute to low health literacy and poor maternal and child health outcomes.     

信息不对称下理财产品刚性兑付成因研究

既然法律或者理财合同没有规定，为什么银行要对其发行的理财产品进行刚性兑付? 已有国内研究以定性分析为主，缺乏规范的模型分析; 已有国外研究或不能完全解释理财产品投资非标资产比例显著低于监管上限，或没有考虑银行理财产品存在事后信息不对称的现实，尚不能完全解释银行理财产品刚性兑付的成因。文章使用成本状态验证方法刻画关于到期收益的信息不对称，使用信息投资方法刻画关于银行努力程度的信息不对称，构建委托投资管理模型分析银行理财产品刚性兑付的形成机理。研究发现，刚性兑付有助于降低信息不对称导致的成本，从而增加银行收益; 当绕过监管的成本低于一定阈值时，刚性兑付便有利可图，银行因而选择刚性兑付。进一步分析表明，引入关于到期收益信息的不完美信号，有助于缓解激励问题、破解刚性兑付。
