Self-control training with maltreating parents

Seeking a method of intervention based on research about correlates of child maltreatment, the authors find that small-group, short-term training in self-control and child management skills gives parents the tools to better handle family stress and develop supportive social networks.     

Barriers to organizational learning: An integration of theory and research

This paper develops a theoretical foundation to describe and explain impediments to organizational learning (OL). Based on the expanded 4I model ( Crossan et al . 1999 . Academy of Management Review , 24 , 522–537), which was further developed by Lawrence et al . (2005 . Academy of Management Review , 30 , 180–191), different learning barriers are categorized and discussed with regard to factors complicating or impeding OL. Finally, the paper analyses the impact of particular barriers on different kinds of organizational units, the relationship between OL barriers, single-loop and double-loop learning, as well as typical combinations of barriers and their respective impact on organizational performance.     

Dual effects of ‘losses disguised as wins’ and near-misses in a slot machine game

Individually, both near-misses and losses disguised as wins (LDWs) have been seen to exert pro-motivational effects on gambling. However, it is not clear whether both structural characteristics are effective within the same game. Participants (n = 40) played a slot machine simulation. The simulation delivered near-misses, wins and ‘full-misses’. Half the participants also received LDWs that occurred independently of the outcomes on the payline. Valence and motivation ratings were collected after each round. Results showed that the LDW group reported increased valence ratings compared to the no-LDW group. Within the LDW group, trials with LDWs also resulted in increased enjoyment compared to trials without LDWs. We distinguished near-misses falling either side of the payline. Near-misses before the payline (NMB) were rated as more motivational than near-misses after the payline (NMA), whereas NMAs were rated as more aversive than NMBs. These differences between the two near-miss types were exacerbated by LDWs. Results demonstrate LDWs increase the trial-by-trial enjoyment of non-win outcomes. The motivational and hedonic effects of near-misses differed for events either side of the payline, and these differences were exaggerated by the presence of LDWs. Thus, near-misses can retain their effectiveness in complex forms of gambling that also deliver LDWs.     

The case for mandatory outpatient treatment

Research on the effectiveness of mandatory outpatient treatment, which is court-ordered mental health follow up, supports its use with individuals who have serious mental illness. Many states already have some kind of mandatory outpatient treatment in place, but it is often underused. Much of the criticism of mandatory outpatient treatment is based on the fact that research demonstrating its efficacy is limited and that its implementation infringes on individuals' rights. However, sufficient evidence can be found in the literature to support its use for some individuals with chronic mental illness living in the community. In addition, the ethical principles of beneficence, utilitarianism, and communitarianism support its use in some situations. Mandatory outpatient treatment is an ethical and effective method shown to be helpful with individuals who have mental illness and are nonadherent to treatment. Expanding its use in appropriate situations is in the best interest of those with serious mental illness and society in general.     

A comparative study of three methods of eliciting preference information

The study reported in this paper compared three methods of eliciting preference information from a decision maker and estimating weights with this information for use in a multiple objective decision making model. The design of the study included issues of implementing computerized interactive models vs more traditional question and answer techniques in the light of different decision models (in terms of level of complexity) and differing levels of decision maker experience. Results indicate that decision makers, regardless of prior exposure to computer terminals, are not intimidated by their use. Additionally, methods which required non-quantitative statements of preferences were preferred over techniques which requested numerical estimates of tradeoffs or marginal rates of substitution between objectives.     

How bad are the effects of bad leaders? A meta-analysis of destructive leadership and its outcomes

While the focus on constructive leadership still dominates leadership research, an increasing number of studies investigate different forms of destructive leadership. This meta-analysis integrates different conceptualizations of destructive leadership and analyzes the relationship between destructive leadership and outcome variables. The search for articles yielded more than 200 studies of which 57 could be included in the meta-analysis. Results indicate the expected negative correlations with positive followers' outcomes and behaviors (e.g., attitudes towards the leader, well-being, and individual performance) and positive correlations with negative outcomes (e.g., turnover intention, resistance towards the leader, counterproductive work behavior). As expected, the highest correlation arises between destructive leadership and attitudes towards the leader. Surprisingly, the next highest correlation was found between destructive leadership and counterproductive work behavior. After discussing the results, an agenda for future research is proposed. Given the negative impact of destructive leadership, more knowledge is especially necessary regarding what triggers destructive leadership.     

Infants' Looking at Possible and Impossible Screen Rotations: The Role of Familiarization

The effects of familiarization and age were examined using Baillargeon's rotating screen paradigm. In Condition A, 4‐month‐olds exposed to 7 180° familiarization trials looked significantly longer at the 180° test events than the 112° test events; there was a familiarity preference. In Condition B, which consisted of 12 instead of 7 180° familiarization trials, the 4‐month‐olds looked significantly longer at the 112° test events than the 180° test events; there was a novelty preference. In Condition C, which was similar to Condition A except that there were 112° familiarization trials, the infants showed a familiarity preference. Thus, 4‐month‐olds experiencing 7 familiarization trials exhibited a familiarity preference, and those experiencing 12 familiarization trials showed a novelty preference. In Condition D, 6‐month‐olds experienced 7 180° familiarization trials; there was no preferential looking to either familiar (180°) test events or novel (112°) test events. Therefore, looking behavior during the test trials was a function of the type of familiarization experience and age and not necessarily an inferred violation of physics.     

Length minimization for Poisson confidence procedures

We study Poisson confidence procedures that potentially lead to short confidence intervals, investigating the class of all minimal cardinality procedures. We consider how length minimization should be properly defined, and show that Casella and Robert's (1989) criterion for comparing Poisson confidence procedures leads to a contradiction. We provide an alternative criterion for comparing length performance, identify the unique length optimal minimal cardinality procedure by this criterion, and propose a modification that eliminates an important drawback it possesses. We focus on procedures whose coverage never falls below the nominal level and discuss the case in which the nominal level represents mean coverage.
