Mutual Interactions Between Speech and Finger Movements

Speech output and finger movements were recorded as right-handed males repeated a syllable while making cyclical finger movements in three experimental conditions: (a) maintaining constant amplitude in both response systems; (b) alternating speech amplitude while attempting to maintain constant finger movement amplitude; and (c) alternating finger movement amplitude while attempting to maintain constant speech amplitude. Observations showed that output of the two response systems was coupled (one syllable was uttered with each finger movement) and entrained in amplitude (the amplitude pattern of the response that the subject attempted to keep constant followed that of the concurrently-active amplitude-modulated response).

These interactions were bidirectional and were present with both left-handed and right-handed finger movements. The interactions are more extensive and subtle than mere interference with one response system by the other, and apparently do not depend on anatomical overlap of the responding neural systems.     

Adapting to Context in Community-Based Participatory Research: “Participatory Starting Points” in a Chinese Immigrant Worker Community

Community-based participatory research (CBPR) is increasingly being used to better understand and improve the health of diverse communities. A key strength of this research orientation is its adaptability to community contexts and characteristics. To date, however, few studies explicitly discuss adaptations made to CBPR principles and processes in response to community context and partners’ needs. Using data from our CBPR study, the San Francisco Chinatown Restaurant Worker Health and Safety Project, and drawing from literature on immigrant political incorporation, we examine the links between the contexts of the Chinese immigrant worker community, adaptations made by our collaborative, and study outcomes. In particular, we explore the concepts of contexts of reception and participatory starting points, which may be especially relevant for partnerships with immigrant communities whose members have historically had lower rates of civic and political participation in the US. We discuss contextual findings such as worker partner accounts of language barriers, economic and social marginalization, and civic skills and participation, as well as subsequent adaptations made by the partnership. We also describe the relative effectiveness of these adaptations in yielding equitable participation and building partners’ capacity. We conclude by sharing lessons learned and their implications for CBPR and partnerships with immigrant communities more broadly.     

I don't believe but I pray: spirituality,instrumentality, or paranormal belief?

These three studies are among the first to systematically compare five Chinese religious groups on intrinsic (spiritual) and extrinsic (instrumental and paranormal) orientation. In Study 1, a Chinese version of the Index of Core Spiritual Experiences was developed. In Studies 2 and 3, spirituality and religious involvement was found to be greatest among Christians, followed in order by Buddhists, Taoists, traditional nones, and other nones. An instrumental purpose for religious activities and paranormal belief was found to be highest among Taoists, followed in order by Buddhists, traditional nones, other nones, and Christians. The results are consistent with the conclusion that Christianity offers the least support for an extrinsic religious orientation and the most support for an intrinsic religious orientation.     

The relationship between learning goal orientation,goal setting,and performance: a longitudinal study

In an educational setting, we examined the relationship of learning goal orientation with goal setting and performance over time. At the first time point, we assessed levels of trait learning goal orientation and asked participants to set performance goals. At each follow‐up time point, we reported to participants their current course grade and allowed them to revise their goals. Learning goal orientation was associated with both setting higher goals and maintaining higher performance over time. Additionally, the relationship of learning goal orientation and performance was found to be mediated by goal setting.     

The Initial Interview with Asian American Clients

When grouped with Pacific Islanders, Asian Americans constitute the fastest growing ethnic group in the United States. In this article, the authors provide background information for understanding the diversity and commonalities within Asian American populations and discuss the challenges of initial assessment with clients who identify as Asian Americans. We conclude this article with guidelines for conducting an effective initial interview with Asian American clients.     

Instrument Development With Web Surveys and Multiple Imputations

This article outlines the development of a tool to assess psychosocial needs in U.S. Air Force (USAF) units. Instrument development began with the construction of an item taxonomy, pretesting procedures (Q-sort; cognitive interviews), and a pilot web survey to document internal consistency and test-retest reliability, followed by two large-scale Web surveys to derive a viable factor structure. Because certain items (e.g., child care) were not relevant to all respondents, multiple imputations to replace missing values were necessary before factor analyses could proceed. Exploratory factor analyses of data from the first Web survey revealed an eight-factor solution; and data from the second Web survey confirmed that the eight-factor solution could be replicated on an independent sample. Developed in accordance with psychometric principles, the final assessment tool tapped a range of psychosocial factors spanning quality of work life, community life, family functioning, and personal well-being.     

Surface tension of substantially undercooled liquid Ti–Al alloy

It is usually difficult to undercool Ti–Al alloys on account of their high reactivity in the liquid state. This results in a serious scarcity of information on their thermophysical properties in the metastable state. Here, we report on the surface tension of a liquid Ti–Al alloy under high undercooling condition. By using the electromagnetic levitation technique, a maximum undercooling of 324 K (0.19 T _L) was achieved for liquid Ti-51 at.% Al alloy. The surface tension of this alloy, which was determined over a broad temperature range 1429–2040 K, increases linearly with the enhancement of undercooling. The experimental value of the surface tension at the liquidus temperature of 1753 K is 1.094 N m^?1 and its temperature coefficient is ?1.422 × 10^?4 N m^?1 K^?1. The viscosity, solute diffusion coefficient and Marangoni number of this liquid Ti–Al alloy are also derived from the measured surface tension.     

Singapore's Cultural Experimentation: Gay Rights,Stem Cells,Casinos and the Evangelical Response

Abstract

Since the early 1990s the Singapore government has been taking a more liberal stance on controversial issues such as gay rights, embryonic stem cell research and the gaming industry. My paper analyses the Singapore state's utilitarian justification and its authoritarian enactment of these liberal policies. The first part looks at the underlying motivation for the cultural makeover. I frame my analysis around the reaction of the Singapore Christian community to these developments. I focus on the criticisms of the state's ‘liberal’ agenda made by Evangelicals, and describe how the People's Action Party (PAP) regime has defended these policies on utilitarian grounds. The first part ends with a comparative analysis of how the ‘cultural war’ debate was played out in Singapore and the USA. In the second part I examine the procedural aspects of this cultural experimentation. I start with a review of Singapore's political reform. I show that civil society in Singapore has attained a new openness. Yet there remain constraints, leading critics to label the PAP-led government as a ‘soft-authoritarian’ democracy. Singapore's cultural policies, I explain, are essentially an ‘elitist’ state-engineered top-down development. This is in contrast to the experience in the USA, where grassroots activists exercise tangible bottom-up influence on how cultural contests are resolved. My main thesis is to argue that Singapore's recent cultural liberalisation is guided by social–economic expediency notwithstanding the alleged moral risks, and that these are state-commanded liberal experimentations, imposed by the ruling elite upon a constituency that is still largely conservative in moral outlook.     

The Relation Between Mothers’ Attitudes Toward Maternal Employment and Social Competence of 36-Month-Olds: The Roles of Maternal Psychological Well-Being and Sensitivity

The relation of mothers’ attitudes on the effects of maternal employment on children, psychological well-being, sensitivity of the mother, and children’s socioemotional development were examined in mothers who worked full time (consistently) and mothers who were unemployed during their children’s early years of growth from 6 months of age. Longitudinal observations of 1,213 mothers and children from age 1 to 36 months from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care were analyzed using structural equation models. Mothers and children benefited when maternal attitudes were consistent with the mothers’ actual employment status. Among consistently employed mothers, those with positive attitudes about employment had better psychological well-being. When mothers who were unemployed, they believed that maternal employment would have positive consequences for their children’s development, they preferred working outside home and they were more likely to show a low level of psychological well-being and poor quality of mother-child relation. Additionally, maternal well-being mediated the relation between a mother’s attitudes and a child’s social competence. For both groups, better psychological well-being of mothers was positively related to better child’s socioemotional outcome. Maternal sensitivity, however, did not mediate the relation between maternal attitudes and child’s social outcomes. The findings shed light on the need for a sensitive measure of characterizing mothers who work versus those who stay at home in order to better understand the effects on a child’s development.     

The immediate and sustained effects of acute exercise on planning aspect of executive function

ObjectiveThe purpose of this study was to clarify the immediate and sustained effects of an acute bout of exercise on the planning aspects of executive function.DesignThis study used a 2 × 4 true experimental design.MethodForty participants were randomly assigned to either the exercise or control groups and completed the Tower of London task prior to, immediately following, 30 min after, and 60 min after cessation of a 30 min, moderate intensity cycling exercise.ResultsAcute exercise positively impacted the total move score, which reflects planning efficiency, immediately after the cessation of exercise. Acute exercise also led to longer total initiation times, which were linked to better response inhibition of planning at 30 and 60 min after the cessation of exercise.ConclusionAcute exercise benefits planning, and the types of planning and the time points at which they were assessed modulate the relationship between acute exercise and executive function. Exercise-induced physiological and biological fluctuations have been proposed to explain the effects present immediately after exercise, and the mechanisms of such effects warrant further exploration.
