Longitudinal patterns of stability and change in coping across three competitions: a latent class growth analysis

An unresolved issue in the coping literature concerns the traitlike versus statelike nature of coping utilization. The aim of this study was to illustrate the benefits of moving beyond the sole reliance on mean-level and rank-order analyses in order to identify heterogeneous patterns of longitudinal stability and change in coping utilization. More specifically, this study hypothesized that not all athletes would change their coping across competitions, nor do all "changers" change in a similar manner. Male soccer players (N = 107) completed a self-reported coping measure after three competitions held over a 6-month period. Results of latent class growth modeling showed three distinct trajectories for each coping dimension (i.e., task, distraction, and disengagement coping), not only indicating linear or quadratic change, but also stability in longitudinal coping utilization. These results highlight the need to account for the multinomial heterogeneity in longitudinal coping utilization and to identify the correlates associated with distinct trajectories of change and stability of coping across competitions.     

In the Shadow of Schumpeter: W. Rupert Maclaurin and the Study of Technological Innovation

J. Schumpeter is a key figure, even a seminal one, on technological innovation. Most economists who study technological innovation refer to Schumpeter and his pioneering role in introducing innovation into economic studies. However, despite having brought forth the concept of innovation in economic theory, Schumpeter provided few if any analyses of the process of innovation itself. This paper suggests that the origin of systematic studies on technological innovation owes its existence to the economist W. Rupert Maclaurin from MIT. In the 1940s and 1950s, Maclaurin developed Schumpeter’s ideas, analyzing technological innovation as a process composed of several stages or steps, and proposed a theory of technological innovation, later called the linear model of innovation. The paper also argues that Maclaurin constructed one of the first taxonomies for measuring technological innovation.     

The design and evaluation of EKE,a semi-automated email knowledge extraction tool

This paper presents an approach to locating experts within organisations through the use of the indispensable communication medium and source of information, email. The approach was realised through the email expert locator architecture developed by the authors, which uses email content in the modelling of individuals’ expertise profiles. The approach has been applied to a real-world application, EKE, and evaluated using focus group sessions and system trials. In this work, the authors report the findings obtained from the focus groups sessions. The aim of the sessions was to obtain information about the participants’ perceptions, opinions, underlying attitudes, and recommendations with regard to the notion of exploiting email content for expertise profiling. The paper provides a review of the various approaches to expertise location that have been developed and highlights the end-users’ perspectives on the usability and functionality of EKE and the socio-ethical challenges raised by its adoption from an industrial perspective.     

Girls in residential care: From child maltreatment to trauma-related symptoms in emerging adulthood

The current study examined the association between child maltreatment and trauma-related symptoms in emerging adulthood – over and above the incidence of such symptoms and conduct problems during adolescence – among a sample of female adolescents in residential care. This study used data from a longitudinal study. The sample was composed of 89 adolescent females who were first interviewed at time of admission in a residential center (M_age = 15.33 years, SD = 1.31) and later in young adulthood (M_age = 19.27, SD = 1.55). At time 1, trauma-related symptoms were assessed with the Trauma Symptom Checklist for Children and conduct problems with a composite measure. At time 2, child maltreatment was assessed retrospectively with the Childhood Trauma Questionnaire, and trauma-related symptoms were reassessed with the Trauma Symptom Inventory-2. Results indicated that child maltreatment, especially emotional abuse and neglect, was related to anxious arousal, depression, and anger in emerging adulthood. This study showed that females from our sample often reported different types of maltreatment during childhood and that these traumatic experiences were significantly associated with poor adult psychological functioning.

The Numbers Makers: Fifty Years of Science and Technology Official Statistics

Official science and technology statistics arefifty years old. Among industrial countries,the forerunners were the United States, Canadaand Great Britain. This paper traces thedevelopment and the construction of S&Tstatistics in these three countries, and theirsubsequent standardization, mainly by theOECD, in the 1960s. It shows how military andscience policy needs drove the construction ofstatistics, until economic considerations cameto dominate their development. It alsodiscusses how statistics interacted withpolitics by way of studies that documentedgaps between OECD Member countries and betweenthe OECD and the USSR.     

Designing a digital instructional management system to optimize early education

The individualization of curriculum features and the matching of those features with learner characteristics (optimization) may help to stimulate learning processes, in particular for children at risk. In a pilot study in two Dutch kindergartens, specific individualization and optimization conditions were codeveloped with teachers and school management. In order to realize the desired changes, a prototype of a digital instructional management system called the Digital Planning Board was developed, implemented and evaluated. Future research aims at the further development of a pedagogical-didactic kernel structure, integrating instructional management software in new instructional practices.     

Smallholder Marketing Cooperatives and Smallholders’ Market Access: Lessons Learned from the Actors Involved

Abstract

Purpose: This article explores the views of Smallholder Marketing Cooperatives’ (SMCs) leaders and staff, to gain insight about the particular roles SMCs play in facilitating smallholders’ market access.

Design/methodology/approach: The authors conceptualized and executed two international workshops in which participants from 42 SMCs from 24 countries deliberated their lessons learned from real-life experiences.

Findings: Participants defined three core issues to be tackled by SMCs to play their role related to facilitating their members’ market access: good FO governance and management; access to capital and networking. They highlighted that smallholders’ market access improves not only as a result of SMCs networking and negotiation with key actors in the public and private sectors, but also due to improved interrelationships among SMCs and other types of Farmers’ Organizations (FOs). Peer-to-peer relationships with other SMCs are critical for mutual learning, collaboration and collective action.

Practical implications: Peer-to-peer relationships among SMCs are crucial for them to overcome the internal and external social dilemmas SMCs are bound to face while improving smallholders’ market access. This goes beyond the three kinds of relationships that scholars have pointed out thus far needed for effective FO development (relationships with members; the public sector and civil society; and with market players). This can be promoted and supported by development programmes.

Originality/value: Most SMC studies concentrate primarily on their efficiency in production and marketing activities. This research proposes looking beyond this perspective, using a qualitative approach to explore the real-life experiences and views of actors involved.
