Ethical Ambiguities in Participatory Action Research With Unauthorized Migrants

There is increased recognition of the importance of well-designed scholarship on how immigration status and policies impact migrants in the United States, including those who are unauthorized. Some researchers have looked to community-based and participatory methods to develop trust, place migrants’ voices at the forefront, and engage collaboratively in using research as a tool for social change. This article reviews three ethical ambiguities that emerged in the process of a series of participatory action research (PAR) projects with migrants in the United States, many of whom were unauthorized. Specifically, three themes are discussed: (a) the tension between the human desire to respond to injustices, and the challenges of doing so in ways that recognize one’s privilege and power as an outsider and supports the migrants’ agency and autonomy; (b) the complex definition, explanation, and dimensions of “risk”; and (c) the complexity of using a methodology (PAR) that prioritizes participants’ collective identity and community in the context of regulations that are designed primarily to protect individuals.     

Deciding as Intentional Action: Control over Decisions

Common-sense folk psychology and mainstream philosophy of action agree about decisions: these are under an agent's direct control, and are thus intentional actions for which agents can be held responsible. I begin this paper by presenting a problem for this view. In short, since the content of the motivational attitudes that drive deliberation and decision remains open-ended until the moment of decision, it is unclear how agents can be thought to exercise control over what they decide at the moment of deciding. I note that this problem might motivate a non-actional view of deciding—a view that decisions are not actions, but are instead passive events of intention acquisition. For without an understanding of how an agent might exercise control over what is decided at the moment of deciding, we lack a good reason for maintaining commitment to an actional view of deciding. However, I then offer the required account of how agents exercise control over decisions at the moment of deciding. Crucial to this account is an understanding of the relation of practical deliberation to deciding, an understanding of skilled deliberative activity, and the role of attention in the mental action of deciding.     

Missional Congregations in Civil Society: An Imagination for God's World

This article provides glimpses of the emerging missional church within the civil society arena from the perspective of congregational case studies. Civil society studies offer five potential community contributions that provide congregations expanded possibilities for discerning and fulfilling their missional vocations in their communities. Framed within trinitarian missional theology, these create a meaningful framework for congregations to expand their imaginations and strengthen their public participation with God's mission in today's world.     

注意缺陷多动障碍的研究与治疗

注意缺陷多动障碍（ADHD）的发病群体多为5岁以后的儿童,主要临床表现是多动、冲动,注意力无法集中,对一项任务不能够有规划进行下去,而且脾气暴躁、易怒。近年来,心理学界、神经科学界和教育学界等对ADHD的研究取得了很多进展。本文概括性地介绍了ADHD病症的基本特征,目前对于患者脑机制损害的研究,并从药理学和行为学等方面讨论了ADHD的治疗方法和手段。     

工作投入研究的现状

工作投入指的是一种与工作相关的积极、完满的情绪与认知状态,具有持久性和弥散性的特点。工作投入对个体的工作绩效和某些工作态度及行为变量,以及顾客满意度、生产力、利润率和单位总体绩效等组织结果变量均具有一定的影响。工作投入的影响因素包括个体特征因素、与工作相关的因素以及与家庭相关的因素等3个方面。文章在对工作投入的相关研究进行全面述评的基础上,指出未来的研究有必要进一步加强对工作投入的干预机制等五方面问题的探讨     

不同铆测验设计下多维IRT等值方法的比较

实际应用中测验往往具有多维结构, 如果仍采用单维IRT方法进行等值, 会得到不准确的结果。因此对于多维结构的测验, 需要使用多维IRT等值方法来实现参数的转换。基于共同题设计, 文章通过模拟研究的方法, 考察了不同铆测验设计下几种多维IRT等值方法的表现, 同时考虑了测验长度、两个维度题目数量的比例、铆测验长度、铆测验的选择策略、两个维度之间的相关和等值群体的能力水平差异六个因素的影响。所比较的多维IRT等值方法有：均值/均值(MM)方法, 均值/标准差(MS)方法, Stoking-Lord (SL)方法, Haebara (HB)方法, 最小平方(LS)方法。结果显示：(1) SL, HB和LS方法得到的等值误差均方根最小, 且在各条件下表现较为稳定。(2) MM和MS方法在非等组条件下呈现出很大的误差均方根。(3)铆测验设计对SL, HB和LS方法的等值结果没有显著影响。(4)在两个维度之间的相关较高, 测验长度和铆测验长度较长, 等值群体的能力水平没有差异的条件下, SL, HB和LS方法得到的等值误差均方根最小。     

图形项目记忆与位置来源提取的ERP研究

采用事件相关电位（ERP）方法研究大学生图形项目记忆与位置来源提取新/旧效应的时、空分布特征。学习屏幕左侧（或右侧）呈现的图形后在屏幕中央呈现某一测验项目（已学图形或新图形）,对受试者进行两类测验：其一是判断该项目是否已学过;其二是将从某侧学过的测验项目判断为目标,而将其它测验项目判断为非目标的来源测验（排除任务）。实验结果表明：图形位置来源提取比项目再认新/旧效应的头皮分布更广,持续时程更长;与前人相同实验范式的研究结果相比,本研究位置来源提取效应的头皮分布范围较广;非目标-旧图形与目标图形新/旧效应的头皮激活程度不同。上述结果说明：图形位置来源提取比项目再认激活的大脑区域更多,这与双重加工模型的观点一致;实验范式和来源知觉的特性共同调节来源记忆新/旧效应的时、空分布特征;意识水平对来源信息提取的新/旧效应存在一定的影响     

ADHD and Behavioral Inhibition: A Re-examination of the Stop-signal Task

The current study investigates two recently identified threats to the construct validity of behavioral inhibition as a core deficit of attention-deficit/hyperactivity disorder (ADHD) based on the stop-signal task: calculation of mean reaction time from go-trials presented adjacent to intermittent stop-trials, and non-reporting of the stop-signal delay metric. Children with ADHD (n = 12) and typically developing (TD) children (n = 11) were administered the standard stop-signal task and three variant stop-signal conditions. These included a no-tone condition administered without the presentation of an auditory tone; an ignore-tone condition that presented a neutral (i.e., not associated with stopping) auditory tone; and a second ignore-tone condition that presented a neutral auditory tone after the tone had been previously paired with stopping. Children with ADHD exhibited significantly slower and more variable reaction times to go-stimuli, and slower stop-signal reaction times relative to TD controls. Stop-signal delay was not significantly different between groups, and both groups’ go-trial reaction times slowed following meaningful tones. Collectively, these findings corroborate recent meta-analyses and indicate that previous findings of stop-signal performance deficits in ADHD reflect slower and more variable responding to visually presented stimuli and concurrent processing of a second stimulus, rather than deficits of motor behavioral inhibition.     

汉字属性匹配与大脑两半球协同活动

在识别汉字时,大脑两半球同时加工的作业成绩是否随加工阶段的增加而显出优势。本研究用汉字形、音、义三种属性分别相匹配的方法用用指定指定提取法,所得实验结果一致表明,形似材料双侧视野同时识别与单侧视野识别成绩无显著差别,而同音与近义材料则表现出双侧呈现显著优于单侧呈现的作业成绩。最后结合脑功能成像研究,对加工阶段影脑半球佃同活动的原因进行了讨论。
