Domestic science: making chemistry your cup of tea

In the early Victorian home, there were plenty of scientific lessons to be uncovered. With the appropriate interrogation, everyday objects could transform seemingly mundane activities such as eating breakfast, washing clothes or reading by candle-light into household lectures that gave children a familiar base from which to explore the hidden properties and marvellous histories of common commodities. Responding to an unprecedented hunger for scientific knowledge, a profusion of introductory texts appeared in the mid-nineteenth century that directed lessons into homes across Britain and beyond. In particular, the science of chemistry found its way into this domestic setting, as writers promoted its practice and practitioners as a source of authoritative expertise on everyday life. One of the most compelling illustrations of this encounter between the public and chemistry took place over a simple cup of tea.     

Measuring the Language Demands of Mathematics Tests: The case of the statutory tests for 11-year-olds in England and Wales

The study reported here investigates various methods for measuring the readability of the language of mathematics test questions used in the national testing programme for 11-year-olds in England and Wales. It is argued that the language used in the questions has a direct influence on test validity. It explores the use of Kane's Formula II and other selected formulae: Dale-Chall, Flesch, FOG and Fry's adaptation of his 1977 formula. These outcomes are compared with an assessment of the reading difficulty of the questions as judged by experienced primary mathematics teachers. The results indicate high levels of agreement between all the formal measures used, but very little agreement between the formal measures and the judgements of teachers. Individual questions are analysed to highlight some of the discrepancies. The conclusion is that there is currently no satisfactory way of measuring the ease or difficulty of the language of mathematics test questions and that further research is urgently needed.     

Emotion Regulation Strategies and Parenting Practices among Parents of Children With Clinic-Referred Conduct Problems

Objective. This study examined the cognitive-affective strategies used by parents of young children with conduct problems to regulate emotions. Key questions concerned the extent to which these emotion regulation strategies are associated with positive and negative parenting practices and predict quality of parenting through interplay with parental depression. Design. Participants were families of toddlers (n = 84) referred to a tertiary-level health service for the treatment of disruptive behavior problems. Parenting practices were indexed through observational coding of parent–child interactions and self-report data on multiple dimensions of positive and negative parenting. Parents self-reported their use of cognitive reappraisal and expressive suppression—the two emotion regulation strategies that are most robustly associated with psychosocial functioning in adults. Results. Associations between emotion regulation strategy and quality of parenting were moderated by parental depressive symptom severity, with distinct effects seen for positive and negative parenting practices. In terms of positive parenting, more frequent use of cognitive reappraisal was associated with increased use of labeled praise among parents with lower levels of depressive symptoms, whereas parents who had higher levels of depressive symptoms engaged in less such praise regardless of how frequently they used reappraisal. In terms of negative parenting, frequent use of cognitive reappraisal and expression suppression were associated with reduced levels of negative parenting, but only among parents with high levels of depression. Conclusions. These findings add to growing support for the integration of emotion regulation strategies into family process models of early-onset conduct problems and related clinical interventions.     

Vacuum interrupter, high reliability component of distribution switches, circuit breakers and contactors

The use of vacuum interrupters(VIs)as the current interruption component for switches,circuit breakers,reclosers and contactors operating at distribution voltages has escalated since their introduction in the mid-1950’s.This electrical product has developed a dominating position for switching and protecting distribution circuits.VIs are even being introduced into switching products operating at transmission voltages.Among the reasons for the VI’s popularity are its compactness,its range of application,its low cost,its superb electrical and mechanical life and its ease of application.Its major advantage is its well-established reliability.In this paper we show how this reliability has been achieved by design,by mechanical life testing and by electrical performance testing.We introduce the“sealed for life”concept for the VI’s integrity.We discuss this in terms of what is meant by a practical leak rate for VIs with a life of over 30 years.We show that a simple high voltage withstand test is an easy and effective method for monitoring the long-term vacuum integrity.Finally we evaluate the need for routine inspection of this electrical product when it is used in adverse ambient environments.     

Conflict Resolution in Preschool Social Interactions

Conflict has frequently been hypothesized to play an important role in development, and yet, until recently, little empirical work has been conducted on preschoolers' social conflicts. The aim of this study was to investigate the types of social issues that produce conflicts, the extent to which children respond positively to protests from others, and how conflicts are resolved. Children were observed in two contexts: semi-structured peer groups in which adults did not intervene, and school-time free-play. The results showed that even when adults do not intervene, children are often responsive to protests from others and resolve conflicts on their own. Differences were also observed for the types of issues that generate conflicts in the two settings and the types of conflicts that children respond to most often. These results indicate that children's conflicts are not solely negative or aggressive and that children's social interactions and their social contexts are multi-dimensional. The findings point to interpersonal aspects of settings, such as the differential role of adults and peers, and to contextual features of settings, such as free-play and sustained play, that should be considered by teachers and parents when structuring social interactive opportunities for young children.     

The Lived Experiences of Men in a Master's Counseling Program

Using phenomenological methodology, the authors explored the experiences of 11 men in a master's‐level counseling program. Participants described the challenges and advantages of being a minority in number, being in a relational environment, and having an awareness of a patriarchal system. These findings suggest the importance of counselor educator awareness of the unique barriers male students face.     

Conflict-Related Emotions During Peer Disputes

The aim of this study was to investigate young children's conflict emotions during peer disputes. Twenty-seven 4- to 5-year-old children participated in four 15- minute sessions in which groups of 3 children played with table toys. Videotapes of these sessions were used to identify all conflicts and conflict roles (initiator, recipient, and observer) and all conflict-related displays of facial emotions (using the AFFEX coding system). Results indicated that initiators', recipients' and observers' emotions differed in the conflict and postconflict periods, but that there were no initial preconflict differences. Overall, conflict initiators almost exclusively expressed happiness, whereas conflict recipients expressed mostly sadness and anger. In addition, children's conflict emotions were related to the frequency with which they initiated and received conflicts. Children who expressed higher percentages of negative emotions as conflict recipients both initiated and received more conflicts, and children who expressed more happiness when initiating conflicts also initiated more conflicts. These findings have implications for how young children develop methods of conflict resolution, and how they form concepts about sociomoral emotions.     

Examining Personal,Perceived, Treatment,and Self-Stigma in College Students: The Role of Parent Beliefs and Mental Health Literacy

ABSTRACT

Although college student mental health concerns are on the rise, many struggling students do not seek psychological treatment when needed. Stigma toward psychological treatment has been demonstrated to influence intent to seek treatment in college student populations. This study aimed to identify factors that predict treatment stigma in college students by examining other forms of student-held stigma, parent-held stigma, and mental health literacy. Results indicated that student-held personal, perceived, and self-stigma all predicted student attitudes toward treatment, while parent-held personal stigma was found to predict self-stigma in students. Those individuals who had received previous education about psychological disorders had lower levels of personal stigma, and, surprisingly, higher levels of self-stigma. Implications for campus outreach programming are discussed.     

Refinements Introduced in the Oddy Test Methodology

The ‘Oddy test’ is an accelerated corrosion test introduced in the 1970s at the British Museum to identify materials likely to emit volatile substances that could harm museum artefacts. It is carried out in many museums all around the world, but not always using the same methodology, which makes it difficult to compare and share test results between institutions. Refinements to the Oddy test methodology have been implemented at the British Museum over the last decade and the aim of this paper is to present these and promote consistency across institutions. The modifications introduced concern the method used to wash the glassware, the preparation of the metal coupons, and standard methods for preparing samples of liquid coatings, adhesives, and adhesive tapes. Finally, conducting Oddy tests is time consuming and measures employed at the British Museum to reduce the number of materials to be tested and streamline testing are described.
