Collective Efficacy as a Key Context in Neighborhood Support for Urban Youth

Neighborhood context, including the physical and social environment, has been implicated as important contributors to positive youth development. A transactional approach to neighborhood asserts that place and people are mutually constitutive; negative perceptions of place are intrinsically bound with negative portrayals of stigmatized groups, including youth. Adult perceptions of neighborhood youth may contribute to an increased sense of alienation and youth antisocial behavior. This study uses street‐intercept interviews with adults (N = 408) to examine the relationship between neighborhood conditions and adult support for neighborhood youth. A path model was used to examine the direct and indirect relationship of neighborhood constructs (safety, aesthetic quality, and walkability) on adult support for neighborhood youth. Neighborhood aesthetic quality and the walking environment were directly associated with adult support for youth, whereas perceived safety was indirectly associated. Collective efficacy partially explained these relationships. Findings support theorized relationships between people and places; improvements to neighborhood physical environment may directly impact resident adults’ perceptions of neighborhood young people.     

School psychology: a public health framework: III. Managing disruptive behavior in schools: the value of a public health and evidence-based perspective

Schools typically adopt individualistic approaches to address disruptive behavior and meet the needs of students with disruptive behavior disorders (DBD) [i.e., Attention Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD), and Conduct Disorder (CD)]. These approaches are often not the most effective and have a limited impact on overall school climate. This article emphasizes the value of an evidence-based and public health perspective in managing disruptive behavior. Information about comprehensive school-based programs and classroom management techniques for disruptive behavior disorders is presented and the important role school psychologists can play in implementing these programs discussed.     

A systematic review of enhanced resurgence paradigms

Following successful treatment in which problem behavior is reduced, it may reemerge as a function of changes in contextual stimuli or the worsening of reinforcement conditions for an alternative response. Although understudied, preliminary research suggests that simultaneous changes in contextual stimuli and reinforcement conditions may represent particularly exigent treatment challenges that create the condition for additive or superadditive relapse. The purpose of the present review was to systematically examine the relapse literature involving simultaneous changes in contextual stimuli and reinforcement conditions in relapse tests and experimental preparations arranged to evaluate their effect on response recovery. We identified 16 empirical articles spanning 27 experiments. Although all experiments included at least one condition that experienced a change in contextual stimuli and worsening of alternative reinforcement conditions, only two experiments included the comparison conditions needed to precisely evaluate additive and superadditive relapse. Our findings establish the preclinical generality of relapse effects associated with simultaneous changes to reinforcement conditions and contextual stimuli across a range of subjects, schedule arrangements, response topographies, reinforcers, and types of contextual changes. We make several recommendations for future research based on our findings from this nascent and clinically relevant subdomain of the relapse literature.     

A Method of Correcting Estimation Failure in Latent Differential Equations with Comparisons to Kalman Filtering

Abstract

Studies have used the latent differential equation (LDE) model to estimate the parameters of damped oscillation in various phenomena, but it has been shown that correct, non-zero parameter estimates are only obtained when the latent series exhibits little or no process noise. Consequently, LDEs are limited to modeling deterministic processes with measurement error rather than those with random behavior in the true latent state. The reasons for these limitations are considered, and a piecewise deterministic approximation (PDA) algorithm is proposed to treat process noise outliers as functional discontinuities and obtain correct estimates of the damping parameter. Comprehensive, random-effects simulations were used to compare results with those obtained using a state-space model (SSM) based on the Kalman filter. The LDE with the PDA algorithm (LDEPDA) successfully recovered the simulated damping parameter under a variety of conditions when process noise was present in the latent state. The LDEPDA had greater precision and accuracy than the SSM when estimating parameters from data with sparse jump discontinuities, but worse performance for diffusion processes overall. All three methods were applied to a sample of postural sway data. The basic LDE estimated zero damping, while the LDEPDA and SSM estimated moderate to high damping. The SSM estimated the smallest standard errors for both frequency and damping parameter estimates.     

To Apologize or Justify: Leader Responses to Task and Relational Mistakes

Abstract

Leadership roles are complex, creating an environment where leaders are likely to make mistakes that result in negative outcomes. We shift the conversation in the literature from examining the effectiveness of mistake responses toward exploring why leaders use different mistake recovery methods. We employ an online experimental method to distinguish between task and relationship mistakes for leaders and suggest that different attributions are made for these two types of mistakes (Study 1). We found that task mistakes are viewed by leaders as more specific and less personal, and that relationship mistakes are viewed as more global, describing the leader’s stable characteristics rather than a specific event. From these findings, we predict that leaders are more likely to apologize for task mistakes and are more likely to justify their relationship mistakes rather than admit wrongdoing for them. We find support for these predictions using a mixed methods approach, employing a laboratory experiment (Study 2) and a critical incident method surveying a panel of leaders (Study 3). As such, this paper extends our understanding of the mistake recovery process for leaders by demonstrating that 1) leaders’ relationship mistakes are viewed as more globally representative of the leader than task mistakes, and 2) leaders are more likely to apologize for task mistakes but more likely to justify relationship mistakes. Relational and task mistakes, however, were not found to be different in regard to their ambiguity or the extent to which they were viewed as a mistake.     

Understanding the unprotected sexual behaviors of gay, lesbian, and bisexual youths: an empirical test of the cognitive-environmental model.

The cognitive-environmental model (CEM; M. Fishbein et al., 1991) was used to understand the unprotected sexual behaviors of 156 gay, lesbian, and bisexual youths. Unprotected anal sex among the males was associated directly with poor protection skills (e.g., incorrect use of barrier methods, such as condoms), poor intentions to use barrier methods, and poor norms by sexual partners concerning barrier methods. Furthermore, the association between low self-efficacy and increasing unprotected anal sex was attributed to poor intentions. Direct associations of unprotected oral sex with poor intentions and poor partner norms also emerged, as did an indirect relation between unprotected oral sex and low self-efficacy via poor intentions. These last 3 findings were replicated when examining unprotected oral or vaginal-digital sex among the females. Relations among the CEM factors supported some CEM-theoretical propositions.
