Do Guyanese mothers' levels of warmth moderate the association between harshness and justness of physical punishment and preschoolers' prosocial behaviours and anger?

This study assessed the moderating role of Indo‐Guyanese mothers' warmth and affection on the associations between harshness and justness of physical punishment and prosocial behaviours and anger in preschoolers. One hundred and thirty‐nine rural Indo‐Guyanese mothers filled out Rohner's Parental Acceptance–Rejection (PARQ) and Physical Punishment Questionnaires (PPQ). Teachers provided assessments of children's prosocial behaviours and anger in preschool settings. Maternal warmth did not moderate the relationship between harshness of physical punishment and children's prosocial behaviours and anger, but it did moderate the relationship between justness of physical punishment and prosocial behaviours for sons as well as the association between justness of physical punishment and anger for daughters. In Caribbean societies where harsh punishment is normative, maternal warmth may work more effectively with justness, and not with harshness of physical punishment, to lower negative childhood behavioural outcomes.     

从毕生发展的视角看健康的贫富差距

健康的贫富差距是所有个体从出生到死亡都需要面对的现实, 也是全球所有国家都存在的社会问题。目前已经有相当的理论和实证研究尝试从毕生发展的视角理解健康的贫富差距。在毕生发展研究中, 健康的贫富差距有其独特的概念和测量方式。该领域重要的理论包括累积优(劣)势假设、累积不公平模型和社会阶层文化周期模型。研究者就儿童期、青少年期、成年期和老年期的健康贫富差距开展了大量的实证研究。未来毕生发展研究和实践的可能方向包括早年和当前社会经济地位的交互作用、社会经济地位的稳定特征和情境效应、跨领域实践干预等。毕生发展视角的健康贫富差距研究有助于理解健康贫富差距的发展根源和形成过程, 是促进国民健康和开展健康公平实践工作的理论基础。     

患者主体意识在现代医学语境中的价值困境分析

患者主体意识在现代医学语境中出现了话语权的失落和自证困难,这可能引起患者的不满。对主客二分的生物医学模式教条和僵化的运用是这一困境产生的主要原因。临床医生仍习惯于将疾病作狭义的生物学理解,造成了对患者主观陈述的轻视。若想突破困境,需要认识到医学具有科学和治疗手段的不同属性,在临床中加强医生对患者的理解与尊重,回归病人的真实世界,构建医患的共同决策环境,借鉴传统中医学身心一体的哲学思想,积极转换理念,探索新的路径。     

职业污名与离职倾向：牵连家人污名与家庭卷入的作用

职业污名对从业者的工作态度和工作行为有着重要影响。以往研究从个体职业身份的视角解释职业污名的作用, 忽略了从业者个体身份认同的多重属性。本研究基于身份边界理论, 提出职业污名会通过牵连家人污名这一机制影响从业者的离职倾向。另外, 这一机制的强弱取决于个体的家庭卷入程度。本研究通过对分属不同职业的384名从业者的3轮问卷调研发现, 家庭卷入调节了牵连家人污名在职业污名与离职倾向之间的中介作用。当个体的家庭卷入水平高时, 这一中介作用更强; 家庭卷入水平低时, 该中介作用更弱。本研究在理论上提出并检验了职业污名影响的新机制, 同时对实际管理工作提出了建议。     

伏隔核和中脑腹侧被盖区内食欲素在吗啡奖赏中的作用

实验采用条件性位置偏爱（CPP）模型考察中脑腹侧被盖区（VTA）和伏隔核壳区（NAcSh）内食欲素（orexin）在吗啡奖赏中的作用。Wistar大鼠分为盐水训练组和吗啡训练组。3轮吗啡（或盐水）匹配训练前,双侧VTA或NAcSh内给予OXR1拮抗剂SB334867（VTA: 0, 1, 5μg;NAcSh: 0, 1, 3μg）;或2轮吗啡（或盐水）匹配训练前NAcSh内给予orexin A（0, 2, 4, 6μg）,观察其对吗啡CPP建立的影响。结果表明,VTA内给予SB334867抑制吗啡CPP建立,并存在剂量效应关系;NAcSh内给予SB334867或orexin A均未影响吗啡CPP建立,而orexin A可增加吗啡处理大鼠的运动性。以上结果表明,VTA和NAcSh内的orexin在吗啡奖赏中扮演的角色不同,可能调控成瘾行为的不同成分     

Young girls' developmental skills in underarm throwing

This paper concerns underarm throwing by girls 7 to 12 years of age. Each movement component by trained and untrained girls in underarm throwing or windmill softball pitching was examined. Movement characteristics of ball release, arm motion, trunk activity, and stepping were analyzed to capture experience- and age-related differences in underarm throwing. A total of 48 young girls participated: 25 untrained (age 9.7 yr.), 14 trained/league (age 10.9 yr.), and 9 trained/formal (10.4 yr.). Performance was videotaped individually and evaluated by three observers. Analyses suggest that, while age did not affect performance, the type of training experience influenced the girls' performance on each of the four movement components. The wrist and trunk were identified as showing the most significant progression with experience. The findings have important implications about changes during acquisition of underarm throwing skills.     

Testing hypotheses regarding the causes of comorbidity: examining the underlying deficits of comorbid disorders

The authors examined the validity of a method commonly used to test alternative hypotheses regarding the causes of comorbidity: the examination of underlying deficits of comorbid disorders. The authors simulated data in which the true causes of comorbidity were known, then compared the patterns of underlying deficits of the comorbid disorders found in the simulated data with the predicted results. The method of examining the underlying deficits of comorbid disorders could distinguish between several comorbidity models, including those that could not be distinguished well using other methods. The ability to distinguish the correct model decreased as the sample size and the correlation between the underlying deficits and the symptom scores decreased, suggesting that the issue of power should be considered carefully.
