Attachment representations and socio-emotional difficulties in alternative care: A comparison between residential,foster and family based children in Chile

Attachment has been assessed in children living in alternative care (AC) settings, such as Residential Homes (RC) and Foster Care (FC). However, no study has been conducted to compare attachment styles in residential, foster and parental care conducted as usual in the same country at the same point in time. There is also a lack of studies conducted in less developed countries. Therefore, the aim of this study was to compare outcomes for children living in three different types of care in Chile. Three groups of children (N = 77), living in (RC), (FC) and with biological parents (PC) were compared. Attachment styles, Indiscriminate Friendliness (IF) and socio-emotional/behavioral difficulties were assessed.Higher rates of secure attachment were observed in the RC group (36.1%) when compared to studies in RC in other countries (mean 18%). However, children in both types of AC were significantly more likely to have insecure and/or disorganized attachment styles than PC children. Higher rates of socio-emotional and behavioral problems were observed in RC (55.6%) and FC (50%) compared to PC (10%). Within type of AC, no significant differences were found, for attachment styles or for socio-emotional/behavioral difficulties, the only difference were the levels of IF, with children in RC having higher levels. As a conclusion, impact of placement in AC can vary between different countries, other factors, rather than only type of AC could better explain differences in attachment security for children. Implications for research and practices are discussed.     

不对称品牌联盟对弱势品牌稀释研究:"攀龙附凤"还是"引火烧身"?

本研究借助最小均方联结模型来解释和分析不对称品牌联盟对弱势品牌的稀释作用.同时,利用实验证明了该种稀释作用的存在,而且可以利用业务多元化和品牌互补性来调节或减缓该负面作用.该研究对中国日益盛行的国内和国际品牌联盟提出警示即中国品牌与国际品牌的联合可能由"攀龙附凤"的惊喜落到"引火烧身"的恶果.     

泉州市中心城区住宅小区体育场地设施建设与管理现状研究

采用文献资料法、实地调查法、问卷调查法、数理统计法等,对泉州市中心城区住宅小区体育场地设施建设及管理现状进行调查。研究表明：泉州市中心城区住宅小区体育用地严重不足,种类单一;大部分住宅小区体育设施没有设立专门的管理机构,且管理人员和体育指导员配置少;体育场地设施以无偿开放为主,开放程度和时间都较好,利用率也较高,但对其的检查和维护频率都较低;住宅小区体育场地设施匮乏与简陋是影响着城市居民就近就便参与体育锻炼的重要因素。

极值问题在证明不等式中的应用

有一类不等式在几何上明显成立,但用通常的代数方法证明起来却比较繁琐,这时一般可用极值问题加以证明。本文举例进行了讨论。     

Promoting psychosocial adaptation of youths in residential care through animal-assisted psychotherapy

The goal of this study was to examine the influence of animal-assisted psychotherapy (AAP) on the psychosocial adaptation of a group of adolescents in residential care who had suffered traumatic childhood experiences and who presented with mental health problems. This study recruited 63 youths (mean age = 15.27, SD = 1.63) who were divided into two groups: a treatment group of 39 youths (19 female and 20 male; mean age = 15.03, SD = 0.51) and a control group of 24 (five female and 19 male; mean age = 15.67, SD = 1.63). The youths who underwent the AAP program had higher school adjustment in comparison to their peers who did not receive treatment. Their hyperactive behavior decreased, and they showed better social skills, more leadership, and fewer attention problems. They also showed a more positive attitude toward their teachers in comparison to controls. No differences were observed in other variables associated with clinical symptoms or personal adjustment. These results suggest that AAP can be effective with teenagers who have suffered childhood traumas and who present with problems of psychosocial adaptation.     

论近代伦敦广场的演变历程

伦敦广场是英国精英阶层的家园,是英国城市化的一个显著特色。广场的功能最初以居住为主,称之为居住型广场,后来人们更注重广场的美学价值,出现了花园广场。随着广场空间逐渐私人化,花园广场最终走向了衰落。伦敦广场的演变历程在某种程度上展示了英国从农业社会向工业社会过渡的历史进程。十七八世纪伦敦贵族率先把乡村自然风景引入城市广场,并注重其建设的系统性和整体性,这种规划观念一直影响到今天世界各国的城市建设。     

生活能源消费的人口敏感性分析——以中国城镇家庭户为例

人口可能不是能源消费的决定性因素或主要因素,但它作为能源消费系统中不可缺少的基础性参数,除了要关注人口数量,人口的结构性因素,以及对引起这些结构性因素变动的人口微观过程,都应该进行科学研究.本文构建了生活能源消费与人口敏感性关系的理论模型,并运用住户调查数据、人口普查数据,以及中国能源统计宏观数据对理论模型进行了实证检验.研究发现,即使是在相同的宏观人口水平下,不同微观人口变动也可能会导致完全不同的生活能源消费情景.人口自然变动、城镇化和老龄化对生活能源消费具有敏感性,人口老龄化的敏感性为负值.但除老年年龄组(60岁及以上)外,年龄结构并不敏感,而人口敏感性的关键钮带是“规模效应”.正是由于人口的结构性因素对生活能源消费有着多重敏感性,不能简单的以人口数量的增减作为判断生活能源消费量变化的唯一指标.事实上,作为结构性因素的人口城镇化已经超过了数量性因素的敏感性强度.最后,将研究结果用于情景分析,对2015年的生活能源消费进行了微观人口分析,并对进一步研究方向提出一些建议.     

偏最小二乘紫外分光光度法同时测定邻、间、对甲酚

本文在乙醇／水（体积比１：８）混合溶剂中，用偏最小、二乘紫外分光光度法同时测定了甲酚的三个同分异构体。在２５０－２８５ｎｍ波长范围内，浓度为０—７０ｕｇ／ｍＬ的三种甲酚均遵守比耳定律。邻、间、对甲酚的最大吸收波长分别为２７０．５，２７１．５和２７７ｎｍ，相应的摩尔吸光系数为１．５６×１０￣３、１．３８×１０￣３和１．６５×１０￣３。测定合成样和工业甲酚的结果相对标准偏差均小３．５％，１／ｍｏｌ·ｃｍ。这个结果符合微量分析要求。
