Using Daily Diary Assessments to Better Understand the Role of Parental Consistency in the Development of Externalizing Child Behavior

Consistent discipline is thought to reduce early child externalizing behavior. It is unclear, however, whether consistency is important mainly within episodes of misbehavior (e.g., threatening with discipline but then giving in) or across episodes of misbehavior (e.g., disciplining each instance of misbehavior). Using a daily diary approach, we examine whether these two types of consistency are associated with disruptive child behavior, concurrently and prospectively. We included two samples (Sample 1: N = 134, Magechild = 30 months, 44% girls; Sample 2: N = 149, Magechild = 5.88 years; 46% girls, at-risk sample) with daily reports of child disruptive behavior and parental responses (Sample 1 = 7 days; Sample 2 = 14 days). Sample 1 parents additionally reported on their reactions over the past month and their child’s externalizing behavior one year later. Within-episode consistency was assessed by the average number of parental reactions per episode; across-episode consistency by the Index of Qualitative Variation; and general consistency by parents’ report of how they had responded to child disruptive behavior in the past month. In both samples correlations between within- and across-episode consistency were significant, but not so strong that they were not differentiated. Again in both samples, regression analyses provided evidence for unique predictive value of across-episode, not within-episode, consistency for daily disruptive behavior. Parental general consistency was longitudinally associated with fewer externalizing problems, whereas within- and across-episode consistency were not. It appears meaningful to differentiate within- from across-episode consistency to better understand the relevance of different aspects of consistency.

MHealth and e-Learning in health sciences curricula: a South African study of health sciences staff perspectives on utilisation, constraints and future possibilities

BackgroundOver the last decade, developments in e-Learning and technologies are creating the groundwork for health sciences and medical education. Literature demonstrates that we have yet to reach any form of consensus about which indicators are needed to assess and teach quality health sciences and medical education through technology or innovation. There is, therefore, a greater need for a tool or platform that is properly constructed, validated and tested within health sciences.MethodsThis paper presents a study, which is part of a larger research project assessing staff and students’ perceptions of the importance and relevance of different aspects of e-Learning and mHealth in health sciences curricula at four universities in South Africa. The specific objectives of this study were to: (i) assess health sciences staffs’ perceptions and understanding of these two applications; and (ii) establish challenges and opportunities of e-Learning and mHealth applications in the health sector, as well as perceptions on the importance and relevance of these applications to their curricula and future practices. A combination of Focus Group Discussions (FGDs) and a key-informant interview was used. A total of 19 staff from four universities participated. Atlast.ti was used for the data analysis and the findings were coded using a primarily deductive thematic coding framework.ResultsThe findings revealed that not all staff members are equipped or trained with new applications or technologies, such as mHealth. Most participants believed that diverse technologies and tools could be integrated with mHealth and e-Learning. Furthermore, participants agree that a new multi-modal platform, in the form of a learning management system (LMS) with relevant applications (and possible plugins) integrated, tailored towards health sciences will benefit all stakeholders, and be valuable to higher education and health sectors.ConclusionsDigitalisation as well as digital citizenship is gradually being integrated into teaching and learning. It is imperative to adapt the health sciences curricula through constructive alignments and promote health sciences education in the current 4IR. This would allow graduates to be better prepared for digitalised practice environments.

Phenomenology and the Digital World: Problems and Perspectives

The last years’ achievements in neuroscience are key for a philosophical analysis focused on the mind-body problem, such as the phenomenological approach.The digital evolution, on the one hand, faces us with the interaction between the world of reality and the world of possibility. This means more than a mere coexistence between these two dimensions. Rather, a concrete feedback occurs among them, and this brings out unprecedented and unavoidable issues with regard to perceptual processes. On the other hand, the digital evolution allows for analyzing data and monitoring environmental systems, thus reasoning in a predictive way, anticipating problems, and checking ex ante their evolution and outcomes.Neuroscience, for its part, with the experiments of Libet and their subsequent interpretations, has highlighted a consciousness of the unconscious made of ballistic and automatic processes, which constitutes the starting phase of our decisions and actions. This further confirmed that sequential and linear thinking is unable to address the brain-environment relationship that is key in understanding any cognitive process.This analysis confirms the relevance of different aspects of Husserl’s phenomenology. There is, however, a “but,” which significantly reduces the extent of adherence to his point of view. Husserl assumed that an implicit horizon precedes or accompanies the acts of conscience. This is the material, impressional, passive, receptive, and, in some way, tacit dimension, strictly connected to the issue of genesis, i.e. the process of constitution of the analyzed entities. Thus, he drew a clear dividing line between this dimension and the phases of the self-controlling, vigilant conscience and its activity. In fact, his approach to the phenomenological problem is mainly oriented toward these phases.

The Impact of Parent Child Interaction Therapy on Temper Tantrums in Pre-school

Temper tantrum behavior is a child's emotional behavior which is shown by explosive anger and some parents consider this behavior to be bad behavior. Temper tantrums can occur in children aged 3-6 years or more. This literature review aims to determine the impact of PCIT (Parent Child Interaction Therapy) on temper tantrums in preschool. In finding this literature review used four databases (ProQuest, Scopus, Pubmed, and Sains Direct) for the design of the study used cross sectional, True Experimental, Observational and Systematic Reviews published in the last five years. The protocol and evaluation of the literature review used the PRISMA checklist to determine the selection of studies that were found and adapted to the objectives of the literature review. The results of literature review analysis of several parents in group and individual PCIT reported that the application of parent-child-based interventions was proven to be effective and has the potential to bring significant and lasting changes in increasing positive behavior in children with external behavior problems. The frequency of problematic child relationship behavior significantly decreased with increasing age of the child. In addition, assessing both positive and negative child relationship behavior could assist parents in understanding the relevance of different aspects for the development of parent-child relationships.

How to use spontaneous customer comments to identify nonlinear background of satisfaction with restaurant services

PurposeThe purpose of this study is to demonstrate how to use customer spontaneous comments to identify which aspects influence the overall customer satisfaction with restaurant services from a nonlinear perspective.Design/methodology/approachThe authors collected data from 399 spontaneous comments about a chain of fast-food restaurants in Brazil. The comments are freely available on the TripAdvisor portal and were extracted and classified according to seven dimensions related to the quality of services: tangibles, reliability, responsiveness, assurance, empathy, quality of the food and price. Next, the authors combine the critical incident technique (CIT) and the penalty-reward contrast analysis (PRCA) to investigate the nonlinear relationship between service quality assessment and overall customer satisfaction.FindingsThe method of integrating CIT with PRCA explains 64.7% of the variation in the customer's assessment of the services provided ( = 0.647). This shows that spontaneous comments from customers are related to their overall satisfaction with the service provided. Besides, the findings suggest that consumers tend to comment more about positive than negative experiences regarding aspects related to food, attendants' empathy and service assurance, and more negative comments about aspects related to responsiveness and price. However, it was found that negative comments have a stronger influence on overall satisfaction than positive comments.Originality/valueUsing comments available for free on the Internet and evaluating how positive and negative comments can jointly influence customer satisfaction, the proposed methodology demonstrates how restaurants can use their customers' spontaneous comments to identify critical aspects to be managed and improved. To the best of authors’ knowledge, this is the first study presenting how restaurants can use customer spontaneous comments, freely available on the internet, to identify the relevance of different aspects of the services provided from a nonlinear perspective. In addition, the present study shows that although customers spontaneously tend to share more positive than negative comments about restaurant services, events related to negative experiences have a stronger influence on overall satisfaction.

Assessing numerical reasoning provides insight into financial literacy

Financial literacy is linked to financial well-being and decision making. While financial literacy and numeracy skills are strongly related, the relevance of different aspects of numeracy (mental arithmetic, math achievement, and numerical reasoning) for financial literacy has not yet been examined. Data were collected from 88 cognitively healthy adults, mean age = 50 years (SD = 15); mean education = 15 years (SD = 2); 61% females; with 56% Caucasian, 36% Black, and 90% non-Hispanic. Financial literacy was measured with the widely used Big Three scale, and numeracy was measured with the Wechsler Adult Intelligence Scale-III, Arithmetic subtest; the Wide Range Achievement Test-IV, Math Computation subtest; and the Weller’s Abbreviated Numeracy Scale (WANS). Regressions analyses were conducted with financial literacy as the outcome variable and each numeracy measure along with demographics (age, sex, and education) as the predictors. In all the models, only the numeracy measures were significant as individual predictors, with numerical reasoning holding the strongest association with financial literacy, followed by mental arithmetic and math achievement. The current study supports the existing literature that numeracy is important for financial literacy, and provides empirical evidence for the specific contributions of individual numeracy measures that clinicians may use to garner impressions about financial skills.

Instantaneous Versus Interval Speed Estimates of Maximum Locomotor Capacities for Whole-Organism Performance Studies

Numerous studies have demonstrated the ecological and social relevance of different aspects of animal locomotor performance, as locomotion is frequently required to capture prey, escape from predators, find mates and defend territories. Typically, maximal performance is quantified using two alternative methods: across distance intervals or across time intervals, the later by extracting the speed observed between a specified number of video frames. Here, we analyze how this choice may influence statistical inference and the derived biological interpretations. Our results indicate that data obtained using 10-cm intervals are categorized, not normally distributed, exhibit lower individual repeatabilities and have four times more variance compared to the data obtained by quantifying speeds across short time intervals. These results have important methodological implications, as they suggest that the choice of method of speed quantification substantially influences the quality and bias of maximal performance descriptors. This may in turn have a profound influence on ecomorphological inference, as it affects our capacity of detecting variation in performance within and across groups, and associations between locomotor performance and other traits.

ABILITIES AND SKILLS IN FIELDS OF SOCIAL WORK – CONCEPTS AND EMPIRICAL RESULTS

In the study programs of bachelor of social work there are different concepts to define abilities and skills as desirable outcomes of the successfully mastered curriculum. In Germany the curricula are based on a generalized “German Qualifications Framework of Social Work”. Two studies are presented to find out, (1) how alumni evaluate the relevance of different aspects of competencies, (2) how these evaluations chances during the first two years after leaving university and (3) how the higher education in social work affects the ability of the alumni to evaluate critical situations in relation to appropriate skills.

Determining the relevance of different aspects of formant contours to intelligibility

Previous studies have shown that “clear” speech, where the speaker intentionally tries to enunciate, has better intelligibility than “conversational” speech, which is produced in regular conversation. However, conversational and clear speech vary along a number of acoustic dimensions and it is unclear what aspects of clear speech lead to better intelligibility. Previously, Kain et al. (2008) showed that a combination of short-term spectra and duration was responsible for the improved intelligibility of one speaker. This study investigates subsets of specific features of short-term spectra including temporal aspects. Similar to Kain’s study, hybrid stimuli were synthesized with a combination of features from clear speech and complementary features from conversational speech to determine which acoustic features cause the improved intelligibility of clear speech. Our results indicate that, although steady-state formant values of tense vowels contributed to the intelligibility of clear speech, neither the steady-state portion nor the formant transition was sufficient to yield comparable intelligibility to that of clear speech. In contrast, when the entire formant contour of conversational speech including the phoneme duration was replaced by that of clear speech, intelligibility was comparable to that of clear speech. It indicated that the combination of formant contour and duration information was relevant to the improved intelligibility of clear speech. The study provides a better understanding of the relevance of different aspects of formant contours to the improved intelligibility of clear speech.

Structure-Dynamics Relationships in Bursting Neuronal Networks Revealed Using a Prediction Framework

The question of how the structure of a neuronal network affects its functionality has gained a lot of attention in neuroscience. However, the vast majority of the studies on structure-dynamics relationships consider few types of network structures and assess limited numbers of structural measures. In this in silico study, we employ a wide diversity of network topologies and search among many possibilities the aspects of structure that have the greatest effect on the network excitability. The network activity is simulated using two point-neuron models, where the neurons are activated by noisy fluctuation of the membrane potential and their connections are described by chemical synapse models, and statistics on the number and quality of the emergent network bursts are collected for each network type. We apply a prediction framework to the obtained data in order to find out the most relevant aspects of network structure. In this framework, predictors that use different sets of graph-theoretic measures are trained to estimate the activity properties, such as burst count or burst length, of the networks. The performances of these predictors are compared with each other. We show that the best performance in prediction of activity properties for networks with sharp in-degree distribution is obtained when the prediction is based on clustering coefficient. By contrast, for networks with broad in-degree distribution, the maximum eigenvalue of the connectivity graph gives the most accurate prediction. The results shown for small () networks hold with few exceptions when different neuron models, different choices of neuron population and different average degrees are applied. We confirm our conclusions using larger () networks as well. Our findings reveal the relevance of different aspects of network structure from the viewpoint of network excitability, and our integrative method could serve as a general framework for structure-dynamics studies in biosciences.

Succinctly assessing the topological importance of species in flower–pollinator networks

The topological importance of species within networks is an important way of bringing a species-level consideration to the study of whole ecological networks. There are many different indices of topological importance, including centrality indices, but it is likely that a small number are sufficient to explain variation in topological importance. We used 14 indices to describe topological importance of plants and pollinators in 12 quantitative mutualistic (plant–pollinator) networks. The 14 indices varied in their consideration of interaction strength (weighted versus unweighted indices) and indirect interactions (from the local measure of degree to meso-scale indices). We use principal components approximation to assess how well every combination of 1–14 indices approximated to the results of principal components analysis (PCA). We found that one or two indices were sufficient to explain up to 90% of the variation in topological importance in both plants and pollinators. The choice of index was crucial because there was considerable variation between the best and the worst approximating subsets of indices. The best single indices were unweighted degree and unweighted topological importance (Jordán's TI index) with two steps (a measurement of apparent competition). The best pairs of indices consisted of a measure of a TI index and one of closeness centrality (weighted or unweighted) or d′ (a standardised species-level measure of partner diversity). Although we have found indices that efficiently explain variation in topological importance, we recommend further research to discover the real-world relevance of different aspects of topological importance to species in ecological networks.

Conceituando o capital social em relação a crianças e jovens: é diferente para meninas?

Este artigo descreve um projeto de pesquisa que explorou a relevância da definição de Putnam (1993) de capital social (como algo que consiste de redes sociais, normas de confiança, reciprocidade, engajamento cívico e participação em comunidades) com crianças e jovens de áreas socialmente desfavorecidas. O artigo também apresenta dados de um estudo sociológico empírico que buscou explorar o significado e a relevância de diferentes aspectos do "capital social" para jovens de 12 a 15 anos que vivem em duas áreas carentes de uma cidade no sudeste da Inglaterra. Baseia-se em descrições que os jovens fazem de seu dia-a-dia e concentra-se em quatro elementos: relatos sobre os pais e a centralidade das mães, diferenças de gênero em relatos sobre o significado e a natureza da amizade, diferenças de gênero em experiências de espaços do bairro e recursos locais e diferenças de gênero nas aspirações dos jovens para o futuro.
