Properties of hypothesis testing techniques and (Bayesian) model selection for exploration‐based and theory‐based (order‐restricted) hypotheses

In this paper, the performance of six types of techniques for comparisons of means is examined. These six emerge from the distinction between the method employed (hypothesis testing, model selection using information criteria, or Bayesian model selection) and the set of hypotheses that is investigated (a classical, exploration‐based set of hypotheses containing equality constraints on the means, or a theory‐based limited set of hypotheses with equality and/or order restrictions). A simulation study is conducted to examine the performance of these techniques. We demonstrate that, if one has specific, a priori specified hypotheses, confirmation (i.e., investigating theory‐based hypotheses) has advantages over exploration (i.e., examining all possible equality‐constrained hypotheses). Furthermore, examining reasonable order‐restricted hypotheses has more power to detect the true effect/non‐null hypothesis than evaluating only equality restrictions. Additionally, when investigating more than one theory‐based hypothesis, model selection is preferred over hypothesis testing. Because of the first two results, we further examine the techniques that are able to evaluate order restrictions in a confirmatory fashion by examining their performance when the homogeneity of variance assumption is violated. Results show that the techniques are robust to heterogeneity when the sample sizes are equal. When the sample sizes are unequal, the performance is affected by heterogeneity. The size and direction of the deviations from the baseline, where there is no heterogeneity, depend on the effect size (of the means) and on the trend in the group variances with respect to the ordering of the group sizes. Importantly, the deviations are less pronounced when the group variances and sizes exhibit the same trend (e.g., are both increasing with group number).     

The relation between off-job recovery and job resources: person-level differences and day-level dynamics

It is well-known that recovery from work and job resources can counteract negative effects of high job demands, but less is known about how off-job recovery and job resources are related to each other. In this two-level daily diary study, 67 employees filled out daily surveys over the course of 8 days to examine this issue. Consistent with our expectations, multilevel analyses revealed that previous day’s detachment from work is positively related to the state of being recovered before going to work, and that the state of being recovered is positively related to one’s level of job resources. Moreover, the results indicated that both person-level differences and day-level dynamics play a role in these relations. Our study highlights the importance of recovering from work in the sense that it does not only help individuals by repairing negative strain effects but can also function as a catalyst in the activation of job resources.     

Ein dramatischer Verlauf einer Demenz

Delirium and dementia are two of the most common causes of cognitive dysfunction in the elderly. In patients with dementia, there is a high risk that changes in location – and especially being admitted to the hospital – may result in serious deterioration of brain function, e.g., delirium. With this case report, the authors emphasize the importance of a thorough medical history, behavioral observation, and progress monitoring in the diagnosis of dementia, while at the same time also question the sense, responsibility, and resource use in daily hospital routine.     

Developing civic engagement in university education: predicting current and future engagement in community services

One of the important goals of education is for students to learn to be responsible civic participants. Thus, the time students spend in college is invaluable. It is important that students learn to participate and be responsible citizens of their community during their time in college (Giles and Eyler in Mich J Community Serv Learn 1:77–85, 1994). In this study, a program to help achieve this important educational goal is presented and evaluated. This involved the examination of the impact of actual participation in a community service activity on students’ changes in attitudes and future intentions. A path model based on predictions drawn from place attachment theory was developed and tested to examine how participating in a community service activity affected students’ place attachment and interests in community service. Two-hundred-and-nine university students participated in the study. Results confirmed the hypothesized model. Implications for enhancing student involvement in their communities and encouraging their development into responsible citizens were discussed.     

How do shoppers behave online? An observational study of online grocery shopping

The pace of online shopping revenue growth means it is important for retailers and manufacturers to understand how consumers behave online compared with their behaviour in brick and mortar stores. We conducted a study in which the detailed behaviour of 40 shoppers was screen recorded while they each undertook an online shopping ‘trip’. The shopping trip comprised purchasing a basket of 12 commonly bought grocery categories at one of two major retailers. The shoppers were all inexperienced in online grocery shopping. Results show that online grocery shopping is fast, even for these consumers who were new to it – half of the online shoppers spent less than 10 seconds purchasing from a category. This result is very similar to that of past studies in physical stores. Indeed, half of all the 12 item‐shopping trips took less than 10 minutes. Also, most purchases were made from the first category page displayed in the retailer's online store. Shoppers also consistently used the default display options chosen by the retailers but used a combination of navigational tools to find their products. We conclude that online shoppers do not behave differently from those offline in terms of time spent or effort expended. Online shopping, in the grocery context at least, seems to primarily reflect a desire for time efficiency on the part of the shopper. In that regard, online shopping seems very similar to in‐store shopping. The study begins the job of documenting shopper behaviour into this new channel and provides practical knowledge for retailers and manufacturers. Copyright © 2015 John Wiley & Sons, Ltd.     

Developmental patterns of emotion regulation in toddlerhood: Examining predictors of change and long‐term resilience

Emotion regulation is critical for optimal functioning across a wide range of domains and may be even more important for individuals in high‐risk environments. While evidence suggests that childhood is generally a period of emotion regulation growth and development, research is needed to examine factors that may contribute to deviations from a typical trajectory. In a prospective study of 1,905 children, latent class growth analysis (LCGA) was used to identify trajectory groups of emotion regulation across toddlerhood (age 14–36 months), examine predictors of those trajectory groups from child temperament, parenting behaviors, and environmental risk, and explore predictions of resilience in 5th grade from the identified groups. LGCA supported a three‐class model, with a Stable Incline group, a Decline group, and a Catch‐Up group. Child negative emotionality, positive and negative parenting, and environmental risk predicted group membership. These trajectory groups in toddlerhood were predictive of child resilient functioning in the 5th grade. Our findings highlight the importance of utilizing developmental models of emotion regulation and provide implications for prevention and early intervention services to enhance emotion regulation development in early childhood.     

Identifying Pseudoscience: A Social Process Criterion

Many philosophers have come to believe there is no single criterion by which one can distinguish between a science and a pseudoscience. But it need not follow that no distinction can be made: a multifactorial account of what constitutes a pseudoscience remains possible. On this view, knowledge-seeking activities fall on a spectrum, with the clearly scientific at one end and the clearly non-scientific at the other. When proponents claim a clearly non-scientific activity to be scientific, it can be described as a pseudoscience. One feature of a scientific theory is that it forms part of a research tradition being actively pursued by a scientific community. If a theory lacks this form of epistemic warrant, this is a pro tanto reason to regard it as pseudoscientific.

The unreachable object? Difficulties and paradoxes in the analytical relationship with borderline patients

The author investigates the main difficulties the analyst encounters in borderline patient analysis, focusing on the specific way in which such patients put the analyst's mental functioning to the test and highlighting the most salient elements of the transference-countertransference dynamic. The author picks out several of the paradoxes that characterize the analytical relationship with these patients, who are constantly seeking contact with the object, which is inevitably traumatic for them. On the basis of highly detailed clinical material, the author demonstrates how - no matter which theoretical-clinical model is adopted - a specific technical problem with these patients is how to manage their intense destructiveness. With these patients, countertransferential difficulties are inevitably predominant because of the looming threat of the destruction of the analytical relationship. Maintaining a balance between the recognition-legitimization of primary narcissistic mirroring needs and the recognition-control of narcissistic demands and attacks on the analytical link is as crucial as it is complex. The paper examines the most important therapeutic and anti-therapeutic factors, highlighting the importance of countertransference analysis and self-analysis as ways of accessing as yet unrepresented elements of the patient and analyst respectively. Particular attention is given to the role played by the analyst's subjectivity and to the enactment.     

Language experiences and vocabulary development in Dominican and Mexican infants across the first 2 years

We longitudinally investigated parental language context and infants' language experiences in relation to Dominican American and Mexican American infants' vocabularies. Mothers provided information on parental language context, comprising measures of parents' language background (i.e., childhood language) and current language use during interviews at infants' birth. Infants' language experiences were measured at ages 14 months and 2 years through mothers' reports of mothers' and fathers' engagement in English and Spanish literacy activities with infants and mothers' English and Spanish utterances during videotaped mother-infant interactions. Infants' vocabulary development at 14 months and 2 years was examined using standardized vocabulary checklists in English and Spanish. Both parental language context and infants' language experiences predicted infants' vocabularies in each language at both ages. Furthermore, language experiences mediated associations between parental language context and infants' vocabularies. However, the specific mediation mechanisms varied by language.
