Despite the growing presence of female immigrants in Western countries, research on the subject highlights two important biases that hinder appropriate explanation of the migratory phenomenon and hence prevent adequate intervention. First, most of the research studies conducted so far focus on male migration; second, the macro‐social perspective has prevailed in these areas of study since socio‐economic and political aspects have taken centre stage in analyses on migratory phenomena, From a gender‐based psychosocial perspective, this study addresses the migration project of 53 women from different South American countries, the Maghreb region and Eastern Europe now living in Southern Spain. For this purpose we conducted 23 in‐depth interviews, and staged six discussion groups with the aim of elucidating to what extent gender‐based psychosocial beliefs—stereotypes, ideology and identity—determine women's migration process. Our results suggest that the main stages in the process—deciding to emigrate, itinerary for social and labour integration in the host country, and general assessment of the migration experience—are strongly influenced by psychosociological constructs which arise as a result of female gender‐typing or female profile.

不同维度特征的共存对归类不确定性特征推理的影响 总被引:1,自引:1,他引:0
探讨在归类不确定的情境下,目标特征和预测特征的共存对特征推理的影响。共包括了三个实验,其中实验1、2考察了非靶类别中目标特征和预测特征的共存性对特征推理的影响,实验3考察了靶类别中目标特征和预测特征的共存性对特征推理的影响。三个实验五个分实验的结果一致支持了修正后的Bayesian规则,排除了“单类说”、“综合条件概率模型”的假设,并进一步修正了Bayesian规则为: 相似文献

项目反应理论等级反应模型项目信息量 总被引:7,自引:1,他引:6
信息函数作为项目反应理论中的一个重要概念,在进行项目和测验分析的工作中,以及在指导测验编制的工作中,有着非常重要的应用价值。信息函数的应用在计算机化自适应测验中更是重中之重,也受到最大关注。然而,关于多级记分项目信息函数特性的研究还比较少。本研究模拟了被试特质水平参数数据和项目参数数据,其中被试特质水平参数生成了121个被试特质水平参数点,项目参数生成了4批不同区分度参数数据,每批数据有126个不同难度等级参数组合模式的项目,每个项目有5个难度等级。通过数据分析后发现,等级反应模型项目提供最大信息量所对应的被试特质水平,是与该项目几个相互临近的难度等级组相适应,既不是只与其中一个难度等级对应,也不一定是与所有难度等级对应。本研究称这种规律为“临近难度等级占优”。这个发现无疑对测验质量分析和测验编制工作,包括计算机化自适应测验编制,具有重要的指导意义 相似文献

Many students struggle with statistical concepts such as interaction. In an experimental group, participants took a paper‐and‐pencil test and then were given training to establish equivalent classes containing four different statistical interactions. All participants formed the equivalence classes and showed maintenance when probes contained novel negative exemplars. Thereafter, participants took a second paper‐and‐pencil test. Participants in the control group received two versions of the paper‐and‐pencil test without equivalence‐based instruction. All participants in the experimental group showed increased paper‐and‐pencil test scores after forming the interaction‐indicative equivalence classes. Class‐indicative responding also generalized to novel exemplars and the novel question format used in the paper‐and‐pencil test. Test scores did not change with repetition for control group participants. Implications for behavioral diagnostics and teaching technology are discussed. 相似文献

谜语问题解决中线索的作用 总被引:1,自引:0,他引:1
汉语谜语在性质上属于顿悟问题,当谜语的谜底为汉语成语时,这样的谜语问题称为成语谜语问题。本研究探讨线索在成语谜语问题解决中的作用特点与方式。三个实验以汉语成语谜语问题为实验材料,采用了语义线索与规则线索,操纵了线索的有效性(有效线索占75%,无效线索占25%),以及线索呈现的时间长短(长时间即阈限上呈现线索(实验1),短时间(20ms)即阈限下呈现线索(实验2与实验3))两个因素。实验1与实验2的任务是要求被试写出成语谜语问题的答案(谜底),实验3则要求被试从6个备择答案中选择出正确的答案。被试为武汉某大学的206名低年级本科生。实验结果表明,(1)无论是阈限上还是阈限下呈现规则线索,有效规则线索对成语谜语问题的解决具有促进作用;(2)有效语义线索对谜语问题的解决具有促进作用,而且,阈限上有效语义线索对谜语问题解决的促进作用更大;(3)阈限上呈现两类无效线索时,它们对成语谜语问题的解决都具有干扰作用;但是,阈限下呈现两类无效线索时,它们对成语谜语问题的解决没有干扰作用。 相似文献

This study examines African American faith based leaders’ attitudes and beliefs about providing HIV prevention education and
services to adolescents. Using a convenience sample, we identified priority adolescent health issues, attitudes about abstinence
messages, and willingness to provide and participate in HIV prevention. Leaders identified drugs, gangs, alcohol, sex, and
pregnancy as priority health issues affecting youth in their institutions. Leaders’ strongly preferred to emphasize abstinence
messages. Although leaders were willing to provide youth with health education, they were not willing to discuss specific
behaviors associated with HIV transmission. African American churches provide a venue to reach African American youth; however,
there are limitations to relying on faith-based HIV prevention services. HIV prevention education should continue to be supplemented
via parents, schools, and public health agencies.

论中医的辨证论治与肿瘤的分子靶向治疗 总被引:1,自引:1,他引:0
辨证论治是中医认识和治疗疾病的基本原则,“同病异治”和“异病同治”是辨证论治的精神实质。恶性肿瘤的分子靶向治疗在很多方面都贯彻了“辨证论治”观念,将所辨的证候落实到受体、基因和各种调控系统上。尽管两者理论基础完全不同,但都强调以患者为中心的综合治疗和个体化治疗理念,对建立正确的临床思维非常重要。 相似文献

Psychology and other behavioral health professions have amassed a broad empirical and clinical literature suggesting many
medical presentations are best responded to with the addition of evidence based behavioral interventions. Despite this, psychology
has not achieved a regular presence as part of medical practice. We suggest specific reasons for the current state of affairs
including clinical, operational, societal labels, financial and training dimensions. Medical, psychological, administrative,
and financial perspectives are reviewed. If the goals of health care system reform are to be reached then we must identify
and challenge the current limitations of health care. This paper will identify the elements that need to be changed in order
for psychology to be integrated into medicine rather than excluded from its policy, planning and operations. 相似文献
