Intergenerational Continuity of Risky Parenting: A Person-Oriented Approach to Assessing Parenting Behaviors

Limited research has investigated the long-term effects of childhood emotional abuse on later forms of parenting. This study utilized a person-centered approach to explore the relation between retrospectively-reported maternal childhood emotional abuse and observed parenting behaviors during a conflict discussion. Data were collected from 53 caregiver-child dyads with children ages 8–11. Results of a model-based clustering procedure (Mclust; Fraley and Raftery 2006) identified three parenting styles (negative, at-risk, positive) that were based on five observed parenting behaviors (emotion regulation, anger, hostility, psychological control, and psychological unavailability). Results indicated that higher levels of childhood emotional abuse were reported by women in the at-risk and negative parenting subgroups. Mothers in the negative parenting and at-risk parenting clusters exhibited greater levels of emotional abuse when compared to the positive parenting cluster. Possible implications are discussed, and results underscore the importance of emotionally abusive developmental experiences in the understanding of risk for maladaptive parenting behaviors.     

Criminal justice involvement and service need among men on methadone who have perpetrated intimate partner violence

Perpetrators of male-to-female intimate partner violence (IPV) may be likely to have multiple service needs, the extent of which may vary with respect to criminal justice involvement. The salience of the criminal justice system and the potential impact on service needs due to arrest and incarceration is underscored given the association between substance use and IPV. This study utilized a sample of men in methadone treatment who perpetrated male-to-female IPV in order to examine associations between criminal justice involvement and perceived additional service need(s). Results indicate that the likelihood of having service needs significantly increased as time since most recent arrest or incarceration decreased. These findings highlight the need and potential benefit that can be derived from greater coordination amongst the criminal justice, IPV prevention, and drug treatment systems and service providers.     

The Dynamics of Enduring Property Relationships in Land

This article proposes a new way of looking at property relationships that will enrich our understanding of how they operate. It focuses on property rights in land which are consensual in origin, although this approach could usefully be applied both to non‐consensual property relationships and to other property types. Recognising both the temporal and spatial dimensions of land, the dynamics approach reflects the fact that most property relationships are lived relationships, affected by changing patterns and understandings of spatial use, relationship needs, economic realities, opportunities, technical innovations, and so on. Although evolving responsively to accommodate changing uses and new rights‐holders, these relationships are nevertheless sustained and enduring. The dynamics lens acknowledges the diverse range of legal, regulatory, social and commercial norms that shape property relations. Our approach also explores how far the enduring, yet dynamic, nature of property relations is taken into account by a range of decision‐makers.     

MIXED COMPANIES AND LOCAL GOVERNANCE: NO MAN CAN SERVE TWO MASTERS

This article looks at the use of institutionalized public–private partnership (PPP) arrangements by local governments for the delivery of different types of infrastructure. It starts by analyzing the mixed company model from a theoretical point of view, in particular the potential for internal regulation and the achievement of a relational agreement. Then, after discussing the practicalities of crafting this type of governance structure, four Portuguese case studies are examined. The empirical evidence on mixed companies operating in the water, waste, transportation, and education sectors shows that the extreme complexity involved in the whole life‐cycle management of these companies usually leads to a poor protection of the public interest.     

The G-20 Moment

Thanks to the draining effects of the Iraq war and the financial meltdown emanating from Wall Street, a powershift away from American dominance is taking place. Caught between a rising China and an America in relative decline, the new leadership in Japan is recalibrating its post-World War II relationships. The G-20 has usurped the role once played by the G-8 as the governing committee of globalization. And the symbiotic coupling of Chimerica, born out of the credit bubble built up over the past two decades, is being put to the test.
In this section, the new prime minister of Japan, the president of the European Union, the president of Brazil and a leading economic historian assess these shifts.     

铅镉联合染毒对大鼠大脑皮质神经细胞的氧化损伤及NAC的保护效应

为研究铅、镉联合对新生大鼠大脑皮质神经细胞的脂质过氧化损伤及N-乙酰半胱氨酸(N-ace-tylcysteine,NAC)的保护效应,以体外培养的新生大鼠原代大脑皮质神经细胞为试验对象,分17个组进行了不同铅、镉浓度的染毒和保护试验,染毒时间为12 h.经超声波粉碎细胞后,测定神经细胞超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GSH-Px)、乙酰胆碱酯酶(TChE)活性和丙二醛(MDA)含量.结果表明,与对照组比较,铅、镉单独染毒组GSH-Px、SOD和TChE活性随染毒越量的增加呈逐渐下降趋势(P<0.05),而CAT活性及MDA含量则呈升高趋势(P<0.05),两者之间具有明显的剂量一效应关系;铅、镉联合染毒对神经细胞GSH-Px、SOD、TChE、CAT活性和MDA含量的改变均较相应的铅、镉单独染毒更为明显,部分组间有显著差异(P<0.05);NAC保护组的MDA含量显著低于相应的染毒组(P<0.05),SOD、GSH-Px、TChE和CAT活性不同程度地高于相应的染毒组,但部分组间差异不显著(P>0.05).铅、镉联合对新生大鼠大脑皮质神经细胞的氧化损伤表现协同毒性效应,NAC可以提高神经细胞的抗氧化能力,对铅、镉及其联合暴露所致的脂质过氧化损伤有一定的保护作用,但保护作用不明显.     

Development of a one-tube extraction and amplification method for DNA analysis of sperm and epithelial cells recovered from forensic samples by laser microdissection

Laser microdissection can be used in forensic casework to isolate specific cell types from mixtures of biological samples. Extraction of DNA from selected cells is still required prior to STR amplification. Because of the relatively pristine nature of the recovered cells, laser microdissection is more sensitive than more traditional methods of DNA analysis, theoretically resulting in DNA profiles from less cellular material. A one-tube extraction and amplification method minimises loss of DNA through liquid transfers and reduces the potential for contamination events occurring. In this paper, the development of a one-tube method for the effective extraction of DNA from laser microdissected sperm and epithelial cells is described. The performance of the in-house method was compared to that of a commercial DNA extraction kit for extraction of DNA from sperm and the downstream compatibility with STR amplification was determined for both sperm and epithelial samples. Full Identifiler™ profiles after 28 amplification cycles were obtained from as few as 15 epithelial cells and 30 sperm.     

精神分析与公共行政:从弗洛伊德到戴蒙德

在传统公共行政学的组织理论中,一个基本的理论前提就是假设人类的行为是理性的,因而对组织的研究总是局限于研究基于人类理性所产生的规范和制度.而自从弗洛伊德创立精神分析方法以来,很多的学者开始运用这一方法来解释组织的行为,创立了精神分析的组织理论.其中,戴蒙德就是著名的代表.精神分析方法在组织理论研究中的运用,拓宽了公共行政研究的视野和思路.但同时也把组织理论从传统发展到了另一个极端,那就是过于强调人类行为的非理性,使得对组织的研究易于陷入不可知的状态。可见,精神分析方法对于公共行政学是有意义的。
