Thriving Together: Conceptual and Methodological Considerations for Examining Thriving in Interdependent Sport

Despite conceptual advances and preliminary associations highlighting the benefits of thriving in sport, opportunities for continued research are numerous. Notably, sport-specific research involving thriving has predominantly taken an individual athlete perspective. Interestingly, evidence from the organisational domain suggests that thriving can manifest at a collective level through interdependent team member interactions. Given the potential for thriving to emerge as a higher-level phenomenon in interdependent sport, a critique of thriving at the group-level is advanced. More specifically, we provide a summary of existing individual athlete thriving literature and organisational thriving research at the group-level (Part 1), propose three approaches to conceptualising thriving in interdependent sport (i.e., common, team, and collective thriving) grounded in multilevel research (Part 2), pose guiding questions and key considerations for future exploration (Part 3), and conclude by emphasising the potential value of examining thriving as a higher-level construct for sport researchers and invested partners (Part 4)

Choosing between his time and her time? Paid and unpaid work of Danish couples

In terms of paid and unpaid work, Danish men and women work the same number of hours per week. But while men do most paid work, women do most unpaid work. We investigate the interaction between paid work and unpaid work for Danish working couples, using the 2001 Danish Time Use Survey. We test several competing theories regarding the intra-individual and intra-household allocation of paid and unpaid work: comparative advantage, bargaining, assortative mating and ‘doing gender’. In addition, we divide unpaid work into ordinary housework and childcare and analyse whether these two activities interact differently with paid work hours. In general, the results favour the assortative mating and ‘doing gender’ theories, but do not support the bargaining or comparative advantage theories. Furthermore, results clearly show that housework and childcare are separate activities with different interaction effects.Labour supply, paid and unpaid work, intra-household allocation of time

Modelling the effects of childcare policy changes: technical supplement to the draft report

This technical supplement provides an interim model to gauge the potential impacts of policy scenarios proposed in the Productivity Commission\u27s report: Childcare and Early Childhood Learning. Introduction: The Childcare and Early Childhood Learning inquiry terms of reference require the Commission to assess the contribution that access to affordable, quality childcare can make to child development and increased participation in the workforce. The Commission has been requested to consider new policy options within the current government funding parameters. In addressing its task, the Commission has developed a model to gauge the potential impacts of policy scenarios proposed in the draft report (referred to as the Productivity Commission Microsimulation Childcare (PCMC) model). This technical supplement presents the interim version of this model and preliminary results used for the draft inquiry report. It also outlines some caveats and limitations to bear in mind when interpreting the results. The main results show that the proposed simplification of the existing childcare arrangements could increase demand for childcare and labour supply from parents. Further, the changes are likely to benefit low- and middle-income households and increase workforce participation in these groups. This paper is divided into 5 sections: 1. The first provides a broad overview of the Commission’s approach to the modelling task and the framework adopted. 2. The second highlights the assumptions, caveats and limitations that are important when considering the results and implications of the Commission’s preliminary modelling. 3. The third details the policy changes being examined. 4. The fourth explains the illustrative, initial results, as well as the intuition behind them. 5. The fifth section concludes by identifying areas of planned further development. The paper also includes appendixes — on model data sources and preparation; a detailed model specification; detailing listing of the parameters used in the modelling; and results for all four policy options described in the draft inquiry report

Instructional support in inquiry-based elementary school science classes: how does it relate to students’ science content knowledge and academic language proficiency?

Inquiry-based science instruction has been proposed as an optimal learning environment for language-integrated teaching. While its potential for developing both content knowledge and language skills has been shown for students with limited language proficiency, research focusing on mainstream classrooms has mainly considered domain-specific learning. Despite the effectiveness of inquiry-based science instruction for student outcomes, research on the role of specific aspects of instructional quality is limited. Addressing this research gap, the present study investigates the relationship between teachers’ instructional support during inquiry-based science classes and elementary school students’ learning gains in science content knowledge and academic language proficiency. Multilevel regression analyses are based on data from 459 German elementary school students from Grades 3 and 4 who participated in a longitudinal intervention study that took place over one school year. Our findings indicate a strong impact of students’ prior knowledge on learning outcomes and compositional effects for the language-related measures. Relations between teachers’ instructional support, as measured by the Classroom Assessment Scoring System (CLASS; Pianta et al., 2008), and students’ learning outcomes did not emerge. In interpreting the results, the overall mediocre quality of teachers’ instructional support needs to be considered.Peer Reviewe

Lipids, membranes, colloids and cells: A long view

This paper revisits long-standing ideas about biological membranes in the context of an equally long-standing, but hitherto largely unappreciated, perspective of the cell based on concepts derived from the physics and chemistry of colloids. Specifically, we discuss important biophysical aspects of lipid supramolecular structure to understand how the intracellular milieu may constrain lipid self-assembly. To this end we will develop four lines of thought: first, we will look at the historical development of the current view of cellular structure and physiology, considering also the plurality of approaches that influenced its formative period. Second, we will review recent basic research on the structural and dynamical properties of lipid aggregates as well as the role of phase transitions in biophysical chemistry and cell biology. Third, we will present a general overview of contemporary studies into cellular compartmentalization in the context of a very rich and mostly forgotten general theory of cell physiology called the Association-Induction Hypothesis, which was developed around the time that the current view of cells congealed into its present form. Fourth, we will examine some recent developments in cellular studies, mostly from our laboratory, that raise interesting issues about the dynamical aspects of cell structure and compartmentalization. We will conclude by suggesting what we consider are relevant questions about the nature of cellular processes as emergent phenomena.Fil: Bagatolli, Luis Alberto.

Real Wages Over The Business Cycle

This paper is an examination of cyclical real wage behavior in the United States since World War II. Like most previous aggregate studies. ours finds little cyclicalitv in aggregate industry real wage data. On the other hand, our analysis of longitudinal microdata from the Panel Study of Income Dynamics reveals substantial procyclicality. We find that this procyclicality is obscured in industry average wage statistics, and to a lesser extent in economywide averages, because those statistics are constructed in a way that gives greater weight to low-wage workers during expansions. The almost complete absence of evidence for countercyclical real wages suggests that movements along labor demand curves have not played a dominant role in cyclical employment fluctuations over the last 40 years. Instead, the procyclicality of real wages indicates that cyclical employment fluctuations have been generated mainly by shifts in labor demand. The sources of these shifts and of the positive slope of the effective labor supply curve, however, remain open to alternative interpretations.

Price Indexes for Acute Phase Treatment of Depression

Although broad trends in medical spending in the U.S. over the last decade have received widespread attention from policymakers, very little attention has focused on the components of those changes. For many other industries, economists typically divide nominal expenditures by an official government price index to decompose these expenditures into price and quantity components. In this paper we construct a new price index for the treatment of one illness depression. Making use of results from the published clinical literature and from official treatment guideline standards, we identify therapeutically similar treatment bundles. These bundles can then be linked and weighted to construct price indexes for specific forms of major depression. In doing so, we construct CPI and PPI-like medical price indexes that deal with prices of treatment episodes rather than prices of discrete inputs, that are based on transaction rather than list prices, that take quality changes and expected outcomes into account employ current, time-varying expenditure weights in the aggregation computations. We find that regardless of which index number procedure is employed time period the treatment price index for the acute phase of major depression has hardly changed remaining at 1.00 or falling slightly to around 0.97. This index grows considerably less rapidly than the various official PPIs -- thus the price index for the treatment of the acute phase of major depression has fallen over the 1991-95 time period. A hedonic approach to price index measurement yields broadly similar results. These results imply that given a budget for treatment of depression accomplished in 1995 than in 1991. Our results suggest that at least in the case of acute phase major depression, aggregate spending increases are due to a larger number of effective treatments being provided.
