The dynamic political economy of support for Barack Obama during the 2008 presidential election campaign

In recent years, students of voting behavior have become increasingly interested in valence politics models of electoral choice. These models share the core assumption that key issues in electoral politicds typically are ones upon which there is a widespread public consensus on the goals of public policy. The present paper uses latent curve modeling procedures and data from a six-wave national panel survey of the American electorate to investigate the dynamic effects of voters’ concerns with the worsening economy—a valence issue par excellence—in the skein of causal forces at work in the 2008 presidential election campaign. As the campaign developed, the economy became the dominant issue. Although the massively negative public reaction to increasingly perilous economic conditions was not the only factor at work in 2008, dynamic multivariate analyses show that mounting worries about the economy played an important role in fueling Barack Obama’s successful run for the presidency.

The Role of Peer Contacts in the Relationship Between Parental Knowledge and Adolescents' Externalizing Behaviors: A Latent Growth Curve Modeling Approach

The purpose of the present study was to examine the direct and indirect effects (through peer contacts) of parental knowledge on adolescents’ delinquent and aggressive problem behavior, using latent growth curve modeling. A sample of 457 13- to 14-year old adolescents at first measurement wave (M=13.27; SD=0.45 years) filled out questionnaires about their parents, peers, and problem behavior three times with 1-year intervals in between. Regarding initial levels of behavior, both direct and indirect effects of parental knowledge were found on aggressive as well as on delinquent behavior. When the rate of change in behaviors was considered, only direct effects were found for both types of problem behavior, whereas indirect effects were absent. Gender differences were also found, with stronger effects of parenting on both aggressive and delinquent problem behavior for boys and stronger effects of peer contacts on aggressive behavior for girls. The present study shows that different behaviors of the externalizing spectrum have different trajectories and diverse relations with parenting and should not be treated as identical.

A study of the intermolecular interactions of lipid components from analogue fingerprint residues

A compositionally simplified analogue of a latent fingermark was created by combining single representatives of each major component of a natural fingermark. Further modified analogues were also produced each having one component removed. The aim of this study was to investigate the intermolecular interactions that occurred within these analogue samples using Fourier Transform Infrared (FT-IR) Microspectroscopy. FT-IR microspectroscopy showed that the absence of squalene and cholesterol significantly restricted the interactions between the other organic constituents within the analogue samples. Investigating the intermolecular interactions of organic compounds within a simplified analogue solution could indicate corresponding interactions that occur within natural fingermarks. These potential interactions could go on to be the target of further investigation of latent fingermark chemistry, and ultimately contribute to a better understanding of the aging processes and degradation mechanisms that take place post-deposition.     

Application of direct PCR in forensic casework

Direct PCR is fast becoming a popular method in forensic science due to the advantages of saving time and money in the lab while increasing the probability of obtaining substantial results has a positive rippling effect. A laboratory is able to reduce the time spent on processing trace DNA samples, which can lead to investigators receiving important information in a timely manner that may not have been possible using standard methods. This study highlights the benefits of direct PCR in forensic casework by analysing trace and touch DNA on a range of substrates and exploring the loss of initial DNA due to extraction.

China in the context of globalization

Although this paper challenges the standard viewpoint that foreign direct investment actually occurred in colonial times it also finds parallels with today’s international finance. Evidence shows that the reverse flow of funds was infinitely much greater than possible foreign investment for at least one colony, the Netherlands East Indies (colonial Indonesia). We calculate for the late colonial period (1880–1939) out of its total colonial surplus at least US$430 billion in today’s terms (about three-quarters of the total) was available for investment. This was far in excess of actual investment. Less than one-third of the available for investment went to colonial Indonesia and a further one-third was invested in other countries. The remainder is attributed to investment in the Netherlands (mainly portfolio), investment by non-Dutch corporations and to some statistical errors and omissions. Furthermore, we indicate their actual vital function within the global economic and financial organisation of the Netherlands in late colonial times. The probability of similar occurrences today is raised.     

跨境电信诈骗案件侦查取证问题研究

跨境犯罪是当前重特大电信诈骗的趋势和特点,它呈现出作案人与被害人、行为地与结果地相分离的情况,给案侦工作带来极大困难。以信息流和资金流为主要取证渠道的双向侦查应当成为侦查重点。要准确把握人证、物证、书证、视频资料、电子证据等形态的基本特性,从信息流查证、资金流查证、网络痕迹查证及服务器监控等方面获取和固定犯罪证据,同时要根据境外窝点的特征精确认定窝点现场,并依据一定的操作规程有效取证。     

Affective blocs: Understanding affective polarization in multiparty systems

Research has suggested that affective polarization (AP)—the extent to which partisans view each other as a disliked out-group—has increased, especially in two-party political systems such as in the US. The understanding of AP in multiparty systems remains limited. We study AP in Finland, characterized by a strong multiparty system and a low level of ideological polarization, between 2007 and 2019. We find that AP has increased, driven mainly by voters evaluating their least favorite party more negatively. We also propose an approach that goes beyond earlier literature, which has mostly used a single aggregate metric to measure AP. Using latent profile analysis, we find that voters are grouped into blocs that view some parties positively and others negatively. This suggests that the complex dynamics of AP in multiparty democracies involve relationships between not just individual parties but between what we call affective blocs that span across party lines.     

人体死后肝细胞DNA含量与死亡时间关系的研究

目的研究人体死后肝脏细胞DNA含量变化与死亡时间的关系及影响因素。方法选取46例已知死亡时间的人体肝脏,根据离体肝脏所处的环境温度分为12—19％（A组）和20—27％（B组）两组,每组23例。在死后24～72h内每隔4h穿刺取肝组织1次,制成细胞悬液,经RNA酶消化,PI染色后,用流式细胞仪测定被检测细胞中含不完整DNA的细胞数所占百分比,所得数据经Exp032V1．2软件计算N值。结果死后24～72h肝细胞N平均值,A组从10．91％增至49．72％,B组从16．22％增至69．63％。两组N平均值随死亡时间的延长均逐渐增高,与死亡时间有相关性,A组r值为：0．598,B组r值为0．77357。并且建立了不同环境温度对应的回归方程。结论在不同环境温度下,死后24～72h内人体肝脏细胞DNA降解均随死亡时间的延长和环境温度的升高而逐渐加快,相关数据可望为死亡时间推断提供一定参考依据。
