How economists think about family resources and child development

Research in child development reveals that the sources, level, stability, and uses of family resources have a profound effect on children's well-being and long-term outcomes. Although that research has incorporated economic constructs and measures, developmentalists generally ignore the formal economic framework for thinking about family resources and child outcomes. Building on the premise that children are an investment, that framework explains how families allocate resources and links that decision to other family choices and to key child outcomes, such as schooling, morbidity, and mortality among others. This article explains economists' general approach to family behavior (the so-called theory of household production) and then describes how that framework is useful for thinking about families and children. The article then outlines how economists model parental investment in children and examines the implications of that approach for developmental science. This discussion is illustrated using an example of interest to developmentalists--the involvement of children and adolescents in after-school activities. A concluding section discusses the benefits of and potential barriers to collaboration between economists and developmentalists.     

Just a knock back? Identity bruising on the route to becoming a male primary school teacher

Men who choose to do ‘women’s work’ and enter the female culture of the primary school can often initially face a range of stereotyped responses to their choice. Drawing on stories from a small sample of trainee and serving male teachers, we adopt the term ‘identity bruising’ to describe the ‘knock backs’ that occur to them in primary schools. How the men react to ‘bruising’ is of considerable interest, given the current concern in the UK to improve the recruitment and retention of men in primary training and teaching. An inductive and reflexive methodology is used whereby we work with the men to explore how they become aware of, understand and negotiate the problematic nature and gendered assumptions of masculinities that underpin the restrictions that they encounter.     

Estimating changes in hydration status from changes in body mass: Considerations regarding metabolic water and glycogen storage

Abstract

The potential for imprecision in the estimation of hydration status from changes in body mass has been outlined previously but the equations derived from these derivations appear inconsistent. Reconciliation of body mass loss in terms of sweat loss and effective body water loss is possible from specific equation sets provided that gains and losses of both body mass and water used in the derivation of sweat loss and to derive effective body water loss are in inclusive equation sets. This is obligatory so that mass and water changes as quantifiable determinants are consistent with both internal processes and external gains and losses. Thus, body mass loss, substrate oxidation, metabolic water, and all the terms used in simultaneous equation sets have to be reconciled not only as identical variables but mathematically balance exactly. The revised equation for effective body water loss given here is different from that originally proposed. Metabolic water is part of body mass loss corrected for substrate oxidation, fluid ingestion, and respiratory water to derive sweat loss and it may not be justified to also include water associated with glycogen as releasable bound water. Accordingly, our calculated effective body water loss is substantially a greater loss than originally supposed but clearly still less than the simple balance between mass loss and fluid ingested.     

Effects of radiant heat exposure on pacing pattern during a 15-km cycling time trial

Abstract

The goal of this study was to investigate the effects of different durations of skin temperature manipulation on pacing patterns and performance during a 15-km cycling time trial. Nineteen well-trained men completed three 15-km cycling time trials in 18°C and 50% relative humidity with 4.5-km (short-heat), 9.0-km (long-heat) or without (control) radiant heat exposure applied by infrared heaters after 1.5 km in the time trial. During the time trials, power output, mean skin temperature, rectal temperature, heart rate and rating of perceived exertion were assessed. The radiant heat exposure resulted in higher mean skin temperature during the time trial for short-heat (35.0 ± 0.6°C) and long-heat (35.3 ± 0.5°C) than for control (32.5 ± 1.0°C; P < 0.001), whereas rectal temperature was similar (P = 0.55). The mean power output was less for short-heat (273 ± 8 W; P = 0.001) and long-heat (271 ± 9 W; P = 0.02) than for control (287 ± 7 W), but pacing patterns did not differ (P = 0.55). Heart rate was greatest in control (177 ± 9 beats · min^?1; P < 0.001), whereas the rating of perceived exertion remained similar. We concluded that a radiant heat exposure and associated higher skin temperature reduced overall performance, but did not modify pacing pattern during a 15-km cycling time trial, regardless of the duration of the exposure.     

The Desegregation Aims and Demographic Contexts of Magnet Schools: How Parents Choose and Why Siting Policies Matter

This paper is designed to specify a set of new opportunities for educators, school administrators, and scholars to realize the practical aims and strategic advantages envisioned in magnet schools. The paper is divided into three distinct sections. In Section I, we examine the extensive research literature on parents’ choice patterns and school preferences in magnet schools and other school-choice programs. In Section II, we compare the reasons parents choose particular schools with the criteria school districts use to select magnet school locations (and themes). This section highlights desegregation goals and district-level magnet school policies pegged to the following questions: What is the policy context for siting decisions in districts with magnet schools? Are siting policies strategically aligned with what is known from the research literature about parents’ school preferences? Do neighborhood characteristics play a part in magnet school siting policies and specific decision-making? In Section III, we use geographic information system (GIS) tools to add both clarity and complexity to the convergence of parent choice patterns and sociodemographic diversity in our four selected school districts. The maps depict the racial and socioeconomic characteristics of the magnet schools in each district, as well as the demographic characteristics of surrounding census tracts (extended school neighborhoods). We conclude that GIS can be a viable option for improving the citing decisions for magnet schools, and that this can allow for the merging of parent choice priorities with educational equity and diversity goals of the district.     

A conceptual model and set of instruments for measuring student engagement in learning

This work has its origins with research into the effects of pedagogy on student engagement and learning outcomes. It summarises the development of self-report and observation instruments for measuring student engagement suitable for early years to senior secondary. The measures are sensitive to the context and experience of learning rather than, as is more common, a general disposition towards learning or school. The measures are distinctive in three ways: (1) they avoid the use of proxies such as attendance which link only weakly to learning outcomes; (2) they are designed to be sensitive to the effect of learning environments and quality of pedagogy on engagement; and (3) they do not assume that the learning environment involves conventional schooling. However, the use of the instruments has also revealed a deep structure to engagement which is a distinctive contribution and links prior research into learner dispositions and interest to the engagement construct.     

Unemployment: A Moral Issue

If any man would know the very cause

Which makes me to forget my speech in rhyme,

All the sweet songs I sang in other time,— I'll tell it in a sonnet's simple clause.

I hourly have beheld how good withdraws

To nothing, and how evil mounts the while; Until my heart is gnawed as with a file,

Nor ought of this world's worth is what it was.
