The Role of Implied Motion in Engaging Audiences for Health Promotion: Encouraging Naps on a College Campus

Abstract

Objective: Lack of sleep among college students negatively impacts health and academic outcomes. Building on research that implied motion imagery increases brain activity, this project tested visual design strategies to increase viewers’ engagement with a health communication campaign promoting napping to improve sleep habits. Participants: Participants (N = 194) were recruited from a large southwestern university in October 2012. Methods: Utilizing an experimental design, participants were assigned to 1 of 3 conditions: an implied motion superhero spokes-character, a static superhero spokes-character, and a control group. Results: The use of implied motion did not achieve the hypothesized effect on message elaboration, but superheroes are a promising persuasive tool for health promotion campaigns for college audiences. Conclusions: Implications for sleep health promotion campaigns and the role of implied motion in message design strategies are discussed, as well as future directions for research on the depiction of implied motion as it relates to theoretical development.     

Identification,Estimation, and Control of Uncertain Dynamic Systems: A Nonparametric Approach

This article is devoted to a presentation of the author' practice of the non-parametric estimation theory for the estimation, filtering, and control of uncertain dynamic systems. The fundamental advantage of this approach is a weak dependency on prior modeling assumptions about uncertain dynamic components. This approach appears to be of great interest for the control of general discrete-time processes, and in particular, biotechnological processes, which are emblematic of nonlinear uncertain and partially observed systems.     

Attitudes toward lesbians,gay men,bisexual women,and bisexual men in Germany

Attitudes toward lesbians, gay men, bisexual women, and bisexual men were assessed in a national representative sample of 2,006 self‐identified heterosexual women and men living in Germany. Replicating previous findings, younger people held more favorable attitudes than older people; women held more favorable attitudes than men; and men held more favorable attitudes toward female than male homosexuality, whereas women did not differentiate. However, women held more favorable attitudes toward homosexuals than toward bisexuals, whereas men did not differentiate. Knowing a homosexual person was an important predictor of attitudes, as was political party preference. Both same‐sex and opposite‐sex sexual attraction were substantially related with attitudes. Our findings support the notion that attitudes toward lesbians, gay men, bisexual women, and bisexual men are related but distinct constructs.     

‘So Much We Still Don't Know’: An Interview with Averil Earnshaw

I was independently told about Averil Earnshaw by three different people in the same six month period. Each of them had heard, or heard of, Averil's presentations on the theme of time-linked intergenerational repetitions, and knew of my own interest in repeating patterns in families. Averil very willingly granted me the interview that follows, and in the course of talking with her, I began to realise that Averil's was yet another story of someone who had formulated an original hypothesis based on repeated clinical observation, and had the courage to present it to gatherings of her peers, only to encounter skepticism, lack of interest, or charges of ‘idiosyncrasy’. Despite Averil's best efforts to show that her hypothesis was consistent with the direction of Freud's own thinking, the psychoanalytic movement had greeted it lukewarmly, and it seemed to me that perhaps it might be of more interest to readers of this Journal, since the older and more psychoanalytically-influenced generation of family therapists (e.g. Bowen, 1978; Skynner, 1976) recognised the general principle of repeating patterns across generations, although not the very particular temporal law that Averil has suggested. The Earnshaw hypothesis is simply enough stated: the emotional and intellectual crises of adults’ lives (including onset of mental and physical illnesses, creative break-throughs and creative blocks) are time-linked to major events in the lives of their same-sex parents at the same age. Often, though not always, says Averil, one experiences a crisis when one is the same age as one's same-sex parent was at the time of the birth of one's next sibling, or even when one is the same age as one's parent was at one's own birth. Averil's short bookTime Will Tell (1995) illustrates this hypothesis with some fifty brief case studies based on biographical data from the lives of famous individuals, as well as with a number of cases from her clinical practice, and examples from her own life. Averil herself recognises that her hypothesis needs to be rigorously tested on a wider sample, but to date, those who have criticised it as ‘merely anecdotal’ have not been willing to undertake such a study.     

Coaching in Introvision für weibliche Nachwuchsführungskr?fte: Erste Ergebnisse

Besides external factors certain thoughts and emotions also constitute a difficulty for women??s career advancement competence. How these thoughts form mental blockades when clumping together and how they limit women??s freedom of action and career advancement is illustrated by the research study ??mental blockades??. This study was part of the integrated research project ??Aufstiegskompetenz von Frauen??Entwicklungspotenziale und Hindernisse??. The results show that mental blockades of female executives can be reduced with the help of introvision coaching.     

Design of Auction Parameters to Reduce the Effect of Collusion

Government departments are increasingly turning to auctions to procure goods and services. Collusion among bidders, however, reduces competition and raises winning bid prices. Since conventional collusion control measures based on the redesign of auction mechanisms are less effective in government procurement auctions, there is a need to devise control measures that decrease the effect of collusion. This article demonstrates how the principles of design of experiments can be applied in a system dynamics model to find the auction parameter values that substantially reduce the effect of collusion in government procurement auctions. This research makes a number of contributions. First, it develops a feedback‐based dynamic mechanism of collusion in government procurement auctions. The mechanism proposes the winning bid price as being determined not by the total number of bidders but by the number of independent bidders. It defines each cartel as one independent bidder regardless of the number of bidders in the cartel. Second, the mechanism is tested by developing a system dynamics model to government auctions for procuring contracts for roadwork projects in India. Third, the principles of experimental design are applied to find the auction parameter values that ensure high bid participation and low winning price‐to‐reserve price ratios.     

An Alternative Theoretical Explanation and Empirical Insights into Overordering Behavior in Supply Chains*

The beer game and the supply line underweighting theory are central to our knowledge of decision making in dynamic environments such as supply chains. The core of these theories is that people are incapable of recognizing the pipeline inventory and this is the main cause of overordering and dysfunctional behavior. This article identifies lacunae in the theoretical and empirical foundations of extant literature and proposes an alternate explanation, a “correction model,” explaining why overreactions occur. We adopt a multi‐method research design, comprising a field case study and laboratory experiments, to ground our findings. [Submitted: July 19, 2010.
