What do I want to feel? Emotion goals in childhood,adolescence, and adulthood

Beliefs about emotion utility can influence context-sensitive emotion goals (i.e., desired emotional responses). Although key for emotion regulation, emotion goals have been overlooked in children and adolescents. In 2018–2019 results of Studies 1 and 2 showed that children (N = 192, M_age = 8.65, 47% girls, 96% White) were less motivated by and found anger less useful in confrontation than adolescents (N = 192, M_age = 12.96, 50% girls, 93% White) and adults (N = 195, M_age = 29.82, 51% women, 96% White). The link between emotion goals and beliefs about emotion utility was weaker in children. In 2021, Study 3 (N = 60, 8-year-olds, 47% girls, 90% White) ruled out expectations as a possible explanation for the previous findings. Context-sensitive utility of emotions may be acquired during development.     

A linear optimization approach to the combined production planning model

Two fundamental processes usually arise in the production planning of many industries. The first one consists of deciding how many final products of each type have to be produced in each period of a planning horizon, the well-known lot sizing problem. The other process consists of cutting raw materials in stock in order to produce smaller parts used in the assembly of final products, the well-studied cutting stock problem. In this paper the decision variables of these two problems are dependent of each other in order to obtain a global optimum solution. Setups that are typically present in lot sizing problems are relaxed together with integer frequencies of cutting patterns in the cutting problem. Therefore, a large scale linear optimizations problem arises, which is exactly solved by a column generated technique. It is worth noting that this new combined problem still takes the trade-off between storage costs (for final products and the parts) and trim losses (in the cutting process). We present some sets of computational tests, analyzed over three different scenarios. These results show that, by combining the problems and using an exact method, it is possible to obtain significant gains when compared to the usual industrial practice, which solve them in sequence.     

The impact of the French policy mix on business R&D: How geography matters

Based on a spatial extension of an R&D investment model, this paper measures the macroeconomic impact of the French R&D policy mix on business R&D using regional data. Our measure takes into account not only the direct effect of policies but also indirect effects generated by the existence of spatial interaction between regions. Using a unique database containing information on the levels of various R&D policy instruments received by firms in French NUTS3 regions over the period 2001–2011, our estimates of a spatial Durbin model with structural breaks and fixed effects reveal the existence of a negative spatial dependence among R&D investments in regions. In this context, while a-spatial estimates would conclude that all instruments have a crowding-in effect, we show that national subsidies are the only instrument that is able to generate significant crowding-in effects. On the contrary, it seems that the design, size and spatial allocation of funds from the other instruments (tax credits, local subsidies, European subsidies) lead them to act (in the French context) as beggar-thy-neighbor policies.     

A methodological approach for object-relational database design using UML

The most common way of designing databases is by means of a conceptual model, such as E/R, without taking into account other views of the system. New object-oriented design languages, such as UML (Unified Modelling Language), allow the whole system, including the database schema, to be modelled in a uniform way. Moreover, as UML is an extendable language, it allows for any necessary introduction of new stereotypes for specific applications. Proposals exist to extend UML with stereotypes for database design but, unfortunately, they are focused on relational databases. However, new applications require complex objects to be represented in complex relationships, object-relational databases being more appropriate for these requirements. The framework of this paper is an Object-Relational Database Design Methodology, which defines new UML stereotypes for Object-Relational Database Design and proposes some guidelines to translate a UML conceptual schema into an object-relational schema. The guidelines are based on the SQL: 1999 object-relational model and on Oracle8i as a product example.Received: 22 January 2002, Revised: 10 June 2002, This paper is a revised and extended version of Extending UML for Object-Relational Database Design, presented in the UML2001 conference [17].     

Anticipatory strategies of team-handball goalkeepers

Abstract

This study seeks to discover whether handball goalkeepers employ a general anticipatory strategy when facing long distance throws and the effect of uncertainty on these strategies. Seven goalkeepers and four throwers took part. We used a force platform to analyse the goalkeeper's movements on the basis of reaction forces and two video cameras synchronised at 500 Hz to film the throw using 3D video techniques. The goalkeepers initiated their movement towards the side of the throw 193 ± 67 ms before the release of the ball and when the uncertainty was reduced the time increased to 349 ± 71 ms. The kinematics analysis of their centre of mass indicated that there was an anticipatory strategy of movement with certain modifications when there was greater uncertainty. All the average scores referring to velocity and lateral movement of the goalkeeper's centre of mass are significantly greater than those recorded for the experimental situation with bigger uncertainty. The methodology used has enabled us to tackle the study of anticipation from an analysis of the movement used by goalkeepers to save the ball.     

What We Talk About When We Talk About Nepantla: Gloria Anzaldúa and the Queer Fruit of Aztec Philosophy

A particular twenty-first-century understanding of the Aztec concept nepantla, one which has recently taken hold in critical education thanks to the writings of Gloria Anzaldúa, does not accurately reflect traditional Aztec history and philosophy. This essay reveals why this is the case, demonstrating in detail the meaning of nepantla within the broader Aztec ontology. It then asks education researchers and practitioners to instead use the theoretical framework of malinalli, the Aztec philosophical concept which best aligns with transformative social justice goals.     

Do university rankings matter? A qualitative exploration of institutional selection at three southern Ontario universities

Concern with university rankings have become widespread throughout post-secondary education (PSE), fuelled in part by administrative concerns that demotions down the rank ladder will produce negative institutional outcomes. There is reason to believe, however, that ranking ‘effects’ may be partially muted in Canadian PSE due to the (1) national system’s flatter hierarchical structure and (2) the generally inconsistent findings produced by domestic research on rankings. Through this study, we provide a qualitative analysis of how rankings shaped the institutional selection processes of 90 undergraduate students across three universities in southern Ontario, Canada. Our data indicate that these students rarely consulted ranking publications, relying instead on reputational information available through their informal networks (e.g. peers, family). We theorise that the unique structural characteristics of Canadian PSE minimise the influence of rankings within this jurisdiction, and discuss the practical implications of this finding for both scholars and administrators.     

Studying studies on teacher reflection and action: An appraisal of research contributions

For decades a substantial body of research on teacher reflection and action has been conducted. This research contains a wealth of information on teachers’ thinking about their daily work in classrooms. But what do these studies tell us about the linkage between thought and action in actual teaching? How do they contribute to our understanding, or do they, in the very selection of their methods, ‘tell only half the story’? To address these concerns, we have engaged in a critical appraisal to learn about the scope and limitations of research contributions and identify criteria that may shed light on exactly what aspects of teacher learning and development are being studied.This appraisal uses an analytic framework to position the various studies that have been conducted. From our analysis, which focuses on the validity criterion of closeness between type of research question and data collection methods, we conclude that the research would profit from a set of more detailed criteria to address some of the limitations inherent in approaches to studying teacher reflection and action.
