Indirect Effects of Maternal Sensitivity on Infant Emotion Regulation Behaviors: The Role of Vagal Withdrawal

The potential indirect effect of observed maternal sensitivity at 5 months on the development of infants' behavioral regulation of emotion from 5 to 10 months (i.e., distraction and maternal‐orientation behaviors) via infant's vagal withdrawal was investigated (N = 230). Results indicated that maternal sensitivity at 5 months was not directly associated with behavioral regulation at 10 months. However, greater maternal sensitivity at 5 months was associated with greater vagal withdrawal at 10 months, after controlling for vagal withdrawal at 5 months. Further, vagal withdrawal at 10 months was associated with greater orientation toward the mother at 10 months, after controlling for 5‐month orientation behaviors. The indirect effect of maternal sensitivity on maternal‐orientation behaviors was significant, suggesting that infant's vagal withdrawal may be one potential mechanism through which maternal sensitivity is related to behavioral regulation.     

Bivariate pointing movements on large touch screens: investigating the validity of a refined Fitts' Law

On the basis of three empirical studies Fitts' Law was refined for bivariate pointing tasks on large touch screens. In the first study different target width parameters were investigated. The second study considered the effect of the motion angle. Based on the results of the two studies a refined model for movement time in human-computer interaction was formulated. A third study, which is described here in detail, concerns the validation of the refined model. For the validation study 20 subjects had to execute a bivariate pointing task on a large touch screen. In the experimental task 250 rectangular target objects were displayed at a randomly chosen position on the screen covering a broad range of ID values (ID= [1.01; 4.88]). Compared to existing refinements of Fitts' Law, the new model shows highest predictive validity. A promising field of application of the model is the ergonomic design and evaluation of project management software. By using the refined model, software designers can calculate a priori the appropriate angular position and the size of buttons, menus or icons.     

A mixed-method exploration of functioning in Safe Schools/Healthy Students partnerships

This paper presents a mixed-method approach to measuring the functioning of Safe Schools/Healthy Students (SS/HS) Initiative partnerships. The SS/HS national evaluation team developed a survey to collect partners’ perceptions of functioning within SS/HS partnerships. Average partnership functioning scores were used to rank each site from lowest to highest. Sites with the most favorable perceptions of partnership functioning were defined as having average scores in the top 10% (n = 10) and sites with the least favorable perceptions of partnership functioning were defined as having average scores in the bottom 10% (n = 10). Qualitative data for these 20 sites were inductively open coded for emergent themes and analyzed for patterns using grounded theory approach. Six themes emerged that distinguished sites reporting the most favorable and least favorable perceptions of partnership functioning: partner engagement, facilitators, barriers, shared decision making, partnership structure, and sustainability. Sites reporting the most favorable perceptions of partnership functioning effectively utilized collaboration processes that facilitate coalition building, such as shared decision making, effective communication, and developing a clearly defined structure. Qualitative themes from this analysis provide evidence of validity for the partnership functioning scale used and illustrate distinguishing features between sites with the most favorable and least favorable perceptions of partnership functioning.     

Men's psychological functioning in the context of women's breast cancer

Previous research indicates that men are affected when their female partners have breast cancer. However, little is known about what predicts men's psychological well-being in this context. The current investigation involved couples in which the woman had early stage breast cancer and explored the degree to which men's positive and negative well-being was related to women's well-being, women's physical symptoms, relationship functioning, and relationship duration. The findings indicate that all of these factors play a role and interact in predicting men's well-being. In particular, when women have a high level of physical symptoms, the typical associations between men's well-being with women's well-being and relationship adjustment no longer persist. Implications for working with couples addressing health problems are provided.     

Effects of differential reinforcement and rules with feedback on preference for choice and verbal reports

We evaluated the effects of differential reinforcement and accurate verbal rules with feedback on the preference for choice and the verbal reports of 6 adults. Participants earned points on a probabilistic schedule by completing the terminal links of a concurrent-chains arrangement in a computer-based game of chance. In free-choice terminal links, participants selected 3 numbers from an 8-number array; in restricted-choice terminal links participants selected the order of 3 numbers preselected by a computer program. A pop-up box then informed the participants if the numbers they selected or ordered matched or did not match numbers generated by the computer but not displayed; matching in a trial resulted in one point earned. In baseline sessions, schedules of reinforcement were equal across free- and restricted-choice arrangements and a running tally of points earned was shown each trial. The effects of differentially reinforcing restricted-choice selections were evaluated using a reversal design. For 4 participants, the effects of providing a running tally of points won by arrangement and verbal rules regarding the schedule of reinforcement were also evaluated using a nonconcurrent multiple-baseline-across-participants design. Results varied across participants but generally demonstrated that (a) preference for choice corresponded more closely to verbal reports of the odds of winning than to reinforcement schedules, (b) rules and feedback were correlated with more accurate verbal reports, and (c) preference for choice corresponded more highly to the relative number of reinforcements obtained across free- and restricted-choice arrangements in a session than to the obtained probability of reinforcement or to verbal reports of the odds of winning.     

Comparing Parents of Children With Down Syndrome at Different Life Span Stages

The present study explored the experiences of parents of children with Down syndrome at different phases of the life span. Using a mixed‐method design, the current study included 445 participants who were divided into 4 groups based on the age of the child: (a) parents of children under 5 years of age (early childhood), (b) parents of children between 5 and 11 years of age (middle childhood), (c) parents of children between 12 and 18 years of age (adolescence), and (d) parents of children over the age of 18 (chronological adults). Parents reported higher coping strategy scores during the middle childhood and adolescent years than early childhood or later years (adult children). Qualitative data identified key areas that parents across the 4 groups reported, including acceptance of the diagnosis, having a positive attitude, their child's developmental level, and other internal and external factors that contribute to their attitudes and coping.     

How good is good enough? Exploring social workers’ conceptions of preparedness for practice

This study examined the question: ‘How do social work practitioners construct preparedness for practice?’ The answer to this question was explored through a research conducted in 2013 consisting of a survey based on the Australian Association of Social Workers’ Practice Standards and interviews with social work practitioners who had experience working with graduating social work students in their final field education placements. The responses of 25 survey participants suggest that social work practitioners generally expect new graduates to have ‘moderate’-level skills across the different practice areas, although a small but notable number of supervisors expect new graduates to have general work preparedness at a ‘developed’ level. In addition to having a clear understanding of and identification with professional values, purpose and ethics, the eight interview participants spoke of the importance of empathy and the ability to work within a multidisciplinary organisational environment.     

Pricing and upper price bounds of relax certificates

Relax certificates are written on multiple underlying stocks. Their payoff depends on a barrier condition and is thus path-dependent. As long as none of the underlying assets crosses a lower barrier, the investor receives the payoff of a coupon bond. Otherwise, there is a cash settlement at maturity which depends on the lowest stock return. Thus, the products consist of a knock-out coupon bond and a knock-in claim on the minimum of the stock prices. In a Black-Scholes model setup, the price of the knock-out part can be given in closed (or semi-closed) form in the case of one or two underlyings only. With the exception of the trivial case of one underlying, the price of the knock-in minimum claim always has to be calculated numerically. Hence, we derive semi-closed form upper price bounds. These bounds are the lowest upper price bounds which can be calculated without the use of numerical methods. In addition, the bounds are especially tight for the vast majority of relax certificates which are traded at a discount relative to the corresponding coupon bond. This is also illustrated with market data.     

“Seeing” is retrieving: Recovering emotional content in leadership ratings through visualization

Our purpose was to develop a new method of questionnaire administration that better captures the role of affect and embodied cognitions in leadership ratings. Study 1 participants visualized their current work supervisor or a neutral stimulus and provided ratings of their work supervisor. Study 2 participants viewed a leadership event and made ratings of leadership and affect. Participants later made identical ratings after visualization. In both quasi-experiments, participants' affect was more strongly related to their leadership ratings following leader visualization. Study 2 showed that participants' leadership and affect ratings were more consistent with their initial ratings, and it showed better episodic memory recall following leader visualization.     

Social work field education: believing in supervisors who are living with disabilities

Much of what is written by non-disabled authors about living with disabilities does not mirror people’s experiences or opportunities. Literature is often written about people’s abilities (or disabilities) rather than by or with people. Discourse about supervision of social work students can risk assuming that supervisors are people who do not identify as living with disabilities. This research is a co-operative inquiry into the experience of being an Australian social work student supervisor who is living with disabilities. The article extends the literature about being a social work field educator to include ability, and values the practice wisdom of experienced social workers including a current student supervisor who is living with a disability.
