An everyday story of systems practice

This article uses a case study to illustrate how a wider systems perspective can be helpful in considering the questions and dilemmas that arise in everyday practice when a practitioner is invited to intervene in a prescribed or limited way with an individual. The case is presented sequentially, with more detailed reflection at various junctures to allow readers to consider for themselves what the options for action are at any given point.     

Facet measures and global job satisfaction

This research was an attempt to find evidence for Scarpello and Campbell's (1983) conclusion that a single-item global measure is more content valid than a composite facet measure for assessing overall job satisfaction. The first study investigated responses from employees in three separate plants who completed a facet measure, a single-item global measure, along with items and facets chosen by an employee committee. Results indicated that the employee-chosen facets accounted for some incremental variance in the prediction of the single-item measure. A second study investigated the relationship between a single-item and a facet measure of benefit package satisfaction when the entire benefit package domain was included in the facet measure. The magnitude of the relationship suggested that the single-item measure of global benefit package satisfaction involved consideration of more than merely satisfaction with each element in the package. Limitations and alternative explanations for the findings are discussed.The helpful comments of Mark E. Tubbs and John W. Jones on an earlier version of this article are greatly appreciated.     

ALTERING SHOPPERS' SUPERMARKET PURCHASES TO FIT NUTRITIONAL GUIDELINES: AN INTERACTIVE INFORMATION SYSTEM

This study reports the results of one effort to help supermarket shoppers alter food purchases to make purchases (and meals) that are lower in fat and higher in fiber. A prototype interactive information system using instructional video programs, feedback on purchases with specific goals for change, weekly programs, and the ability to track user interactions and intended purchases was evaluated. The major dependent measure was users' actual food purchases as derived from participants' highly detailed supermarket receipts. After a 5- to 7-week baseline phase, participants were randomly assigned to an experimental or control condition for the 7- to 8-week intervention phase. A follow-up phase began 5 to 8 weeks after participants completed the intervention and discontinued use of the system. The results indicated that experimental participants, when compared to control participants, decreased high fat purchases and increased high fiber purchases during intervention, with evidence for some maintenance of effect in follow-up. Plans for increasing the use and impact of the system are discussed.     

Free Speech Fallacies as Meta-Argumentative Errors

Free speech fallacies are errors of meta-argument. One commits a free speech fallacy when one argues that since there are apparent restrictions on one’s rights of free expression, procedural rules of critical exchange have been broken, and consequently, one’s preferred view is dialectically better off than it may otherwise seem. Free speech fallacies are meta-argumentative, since they occur at the level of assessing the dialectical situation in terms of norms of argument and in terms of meta-evidential principles of interpreting how and why people follow (or fail to follow) argumentative rules. Our plan here is to begin with a brief explanation of meta-argument and meta-argumentative fallacy. We will then turn to the variety of forms of the free speech fallacy, which we will explain as meta-argumentatively erroneous.

     

Teaching behavior analysts in an early intensive behavioral intervention setting to conduct a structured mealtime protocol

Children with autism spectrum disorder often display feeding problems, such as consumption of a limited variety of foods. It is also common for these children to be enrolled in early intensive behavioral intervention (EIBI) services for comprehensive treatment. Combined, these factors make it possible that behavior analysts will have a role in a child's clinical care related to feeding. However, given that the etiology of pediatric feeding disorders is complex and multifactorial, clinicians should ensure they have sufficient training and a setting that is appropriate for assessment and treatment. Therefore, we evaluated the effects of behavioral skills training in an EIBI setting to conduct a structured mealtime protocol. Training resulted in increases in procedural integrity, and we replicated these effects for all participants.     

Evaluating the efficacy of pictorial preference assessments with children who engage in food selectivity

Preference assessments are used in practice with individuals who engage in food refusal and selectivity to identify foods that a child will readily consume before assessment and treatment. Traditional edible preference assessments may be challenging for children who engage in food refusal or selectivity as the child may not consume foods, but rather engage in inappropriate mealtime behavior simply due to the presence of food. Alternative modality preference assessments, such as pictorial, may offer benefits compared to traditional preference assessment formats (e.g., stimulus preference assessment and paired-stimulus preference assessment). The use of pictures may reduce any evocative effects of the presence of food and result in choice-making without inappropriate mealtime behavior. Experiment 1 assessed the correspondence between the hierarchies yielded from pictorial preference assessments (with and without access) to a standard edible preference assessment. Experiment 2 evaluated the accuracy of each preference assessment by presenting foods identified as preferred and non-preferred to determine if the child would accept them. Results suggested that pictorial preference assessments with access corresponded the most with the traditional edible preference assessment. Also, for one individual, the traditional preference assessment did not accurately identify foods that the participant would consume, while the pictorial preference assessment without access yielded a hierarchy.     

The impact of customer engagement on customer happiness

Previous studies have found relationships between variables that predict happiness and engagement. While this suggests that engagement is a basis for generating customer happiness, the literature does not provide sufficient confirmatory evidence. Thus, the effects of different engagement intensities remain unclear. Focusing on conditions related to the Starbucks brand, this study analyzed how (1) passive and active engagement impacted customer happiness and (2) happiness impacted word of mouth (WOM) and purchase intention. Data were collected through an online survey among 802 Peruvian customers, all of whom were recruited via non-probabilistic sampling. Because two exogenous variables were considered formative (i.e., customer engagement and customer happiness), a partial least-squares structural equation model (PLS-SEM) was used for the analysis. In sum, engagement (both passive and active) significantly and positively impacted customer happiness, which then positively impacted WOM and purchase intention. Given that engagement is associated with variables that are broadly related to happiness, this study makes new contributions by (i) clarifying how customer engagement can generate customer happiness, (ii) identifying differences between active and passive engagement, and (iii) adding evidence for use in the debate on the purpose of marketing and traditional practices such as engagement. As discussed in the paper, these findings have theoretical and practical implications for brand managers.     

One-year prediction of cognitive decline following cognitive-stimulation from real-world data

Clinical evidence based on real-world data (RWD) is accumulating exponentially providing larger sample sizes available, which demand novel methods to deal with the enhanced heterogeneity of the data. Here, we used RWD to assess the prediction of cognitive decline in a large heterogeneous sample of participants being enrolled with cognitive stimulation, a phenomenon that is of great interest to clinicians but that is riddled with difficulties and limitations. More precisely, from a multitude of neuropsychological Training Materials (TMs), we asked whether was possible to accurately predict an individual's cognitive decline one year after being tested. In particular, we performed longitudinal modelling of the scores obtained from 215 different tests, grouped into 29 cognitive domains, a total of 124,610 instances from 7902 participants (40% male, 46% female, 14% not indicated), each performing an average of 16 tests. Employing a machine learning approach based on ROC analysis and cross-validation techniques to overcome overfitting, we show that different TMs belonging to several cognitive domains can accurately predict cognitive decline, while other domains perform poorly, suggesting that the ability to predict decline one year later is not specific to any particular domain, but is rather widely distributed across domains. Moreover, when addressing the same problem between individuals with a common diagnosed label, we found that some domains had more accurate classification for conditions such as Parkinson's disease and Down syndrome, whereas they are less accurate for Alzheimer's disease or multiple sclerosis. Future research should combine similar approaches to ours with standard neuropsychological measurements to enhance interpretability and the possibility of generalizing across different cohorts.     

Functions of the Black Church in a Global Society: A Du Boisian Approach

Globalization's impact on local communities is a topic that religious congregations should address as a means of moral and socioeconomic well-being. This is especially important for the Black Church if it hopes to continue supporting the socioeconomic outcomes of its congregants and community members, as it has in the past. Using Du Boisian assessments of the functions of the Black Church, this study assessed how today's congregations can serve similar functions as the congregations that Du Bois studied, while exploring contemporary concerns. With an explanatory sequential research design, this study surveyed Philadelphia-based congregations (N = 108) to assess their understanding of and engagement with the impact of globalization on future generations, paired with subsequent interviews (N = 15) for deeper analysis. The survey included clergy members and youth leaders of various races and religious traditions. With an eye toward equity and considering Philadelphia's diverse demographics, the in-depth semistructured interviews centered on Black churches in Philadelphia. The core findings highlight that clergy members in Philadelphia recognize the importance of prioritizing global issues as a means of social betterment and that a special lens toward race should be considered when looking to solve socioeconomic global issues.
