Relationships between open source software companies and communities: Observations from Nordic firms

This paper deals with the relationships between firms and communities in open source software (OSS). A particular feature of OSS is that important resources are not directly controlled by firms, but partly reside within communities that co-exist with the firms. Despite this, firms explicitly try to utilize the resources within these communities in order to create and appropriate value. Consequently, the relationships that firms have to these communities influence their way of doing business. Based on case studies of Nordic OSS firms, a typology consisting of symbiotic, commensalistic, and parasitic approaches to handle the firm-community relationship is developed. Depending on the chosen approach, firms encounter different managerial issues and also use different operational means of subtle control. While firms relying on a symbiotic approach have greater possibility to influence the community through subtle means of control, they are also confronted with more challenging managerial issues.     

The Child Abuse Potential Inventory and pregnancy outcome in expectant adolescent mothers.

OBJECTIVE: The study explores the prenatal Child Abuse Potential (pCAP) scores derived from the Child Abuse Potential Inventory administered to expectant adolescent mothers. The aim of the study was to assess the association of the pCAP scores with maternal negative prenatal behaviors, and evaluate the contribution of the pCAP scores to neonatal morbidity. METHOD: The pCAP scores, demographic data, and self-report on prenatal behaviors were obtained during the second half of the pregnancy in a sample of 45 poor single adolescent mothers. A pediatrician blind to the prenatal data reviewed the neonatal records to assess neonatal morbidity. Maternal prenatal records were reviewed for obstetric risk assessment by an obstetrician who was blind to the rest of the data. The relations among the pCAP scores, prenatal behaviors, and neonatal morbidity were analyzed. RESULTS: In the prenatal period, the pCAP scores were positively correlated with self-reported prenatal smoking and substance use. The multiple linear regression analysis showed that the pCAP scores significantly contributed to neonatal morbidity independently of obstetric risk factors. CONCLUSIONS: The Child Abuse Potential scores obtained during pregnancy in poor single adolescent mothers reflect domains of maternal functioning that are associated with negative prenatal behaviors and appear to be important for predicting neonatal morbidity. Further studies are warranted to validate the prenatal use of the Child Abuse Potential Inventory.     

Neuromuscular,biochemical and perceptual post-match fatigue in professional rugby league forwards and backs

Abstract

In this study, we investigated changes in creatine kinase, perceptual and neuromuscular fatigue of professional rugby league players after match-play. Twenty-three male rugby league players (10 backs, 13 forwards) had their creatine kinase, perceptual ratings of fatigue, attitude to training, muscle soreness, and flight time in a countermovement jump measured before and 1 and 2 days after (day 1 and day 2 respectively) league matches. Total playing time, offensive and defensive contacts were also recorded for each player. Creatine kinase was higher both 1 and 2 days after than before matches (P < 0.05) in forwards and backs. Similarly, perceived fatigue and muscle soreness were higher than pre-match on both days 1 and 2 (P < 0.05), but did not differ between groups (P > 0.05). Jump performance was lower on day 1 but not day 2 for both groups (P < 0.05). While total playing time was longer in backs (P < 0.05), relative frequencies for all contacts were greater in forwards (P < 0.05). Contacts for forwards were correlated with all markers of fatigue (P < 0.05), but only flight time was correlated with offensive contacts in backs (P < 0.05). Despite the mechanisms of fatigue being different between forwards and backs, our results highlight the multidimensional nature of fatigue after a rugby league match and that these markers do not differ between positions.     

National technology gaps and trade - an empirical study of the influence of globalisation

This paper examines the hypothesis that economic internationalisation is acting to reduce the importance of national technology ‘gaps’ as determinants of trade patterns and performance. The cross-country analysis uses two approaches to assess the dynamic nature of the relationship between national investment in technological capability (proxied by both R&D activity and human capital) and technology-intensive (TI) trade performance. Natural resource endowment and the changing impact of physical capital formation are also investigated. The study includes approximately 48 nations and is based on data from the mid-1970s to 1990. The empirical evidence from one approach undertaken does not support the globalisation hypothesis as national investment in technology and human capital is shown to have maintained its link to international trade success in TI manufactures over the study period. However, the findings of the alternative approach are ambiguous. A positive association between technology investment catch-up and ongoing TI manufacturing trade performance is evident for the newly industrialised economies (NICs), but the results suggest that an inverse relationship may apply for many of the ‘mature’ Western economies.     

An Exploratory Study of Stress in a British University

This paper reports an exploratory study of stress and psychological well-being in British University staff. Unlike previous studies of stress in University staff, this study examines stress not only in relation to lecturing staff, but also research and support staff. Principal components analysis of a fifteen item stressor scale revealed two orthogonal dimensions, relating to quantitative overload stressors and role stressors respectively. Both were found to be related to a measure of psychological well-being. Differences in these stressor factors were found between the various types of university employee; academic staff were found to report more work load and managerial stressors, but reported fewer role stressors.     

“Special Support” in Preschools in Sweden: Preschool staff’s definition of the construct

This study investigates the definitions of the construct “young children in need of special support” given by preschool staff in Sweden in 540 preschool units. The study has a mixed‐methods design based on qualitative analysis of an open‐ended question and quantitative analysis of questionnaire responses. The results reveal two general perspectives in definitions of the construct, a child perspective and an organisational perspective. Units with a child perspective had a higher proportion of children in need of special support, especially girls. The study highlights that the term “children in need of special support” is partially socially constructed and is partially based on perceived child characteristics. The perceptions of what is considered to be a child in need of special support held by staff in a unit may impact on the services provided to children in need of special support.
