Managing testing activities in telecommunications: A case study

This paper examines ways of managing testing more efficiently and effectively. The importance and the workload of testing have been growing constantly in the telecommunication industry, as a result of shorter product lifecycles and decreased time-to-market. At the same time, the complexity of products has increased with a decrease in physical dimensions. Managers face enormous challenges in developing knowledge and effective testing processes. This case study proposes the application of two models, a testing optimization model and an extended V2M2 (Verification Validation Maturity Model) model, for managing the value of testing. In the empirical part of the study, the present state of testing management is examined.     

Stretching the borders: how international business travel affects the work–family balance

This study examined the consequences of international business travel for the balance between work–family domains by exploring how international business travellers and travellers’ partners manage the boundaries between work and family in order to maintain the balance. Interpretative phenomenological analysis was used in analysing the semi-structured interviews of 10 male travellers and 10 partners. Because of its irregular nature, international business travel affects the personal life and the family of business travellers. Work-related travel also has an impact on how travellers and their partners construct, manage and negotiate borders between work and family in order to avoid an imbalance between these domains. Integration of work and family is usually inevitable in international business traveler families. Integration may lead to role blurring and thus lead to imbalance.     

‘Singing acts’ from the deep North: critical perspectives on northern exotics,contemporary ethnic music and language preservation in Sámi communities

This paper discusses the relationship of northernness and performances of contemporary ethnic popular music, within the context of critical geography and postcolonial theory. The focus is on the Sámi ethnic minorities of northern Finland. The North of Finland, ‘nature-Finland’, is understood here as an imaginative region which over the course of several centuries has been constituted through various forms of stereotyping, mystifying, exoticising and othering of Sámi minorities in accordance with the nationalist endeavours of Southern Finland. While these stereotypes and preconceptions of northernness have delimited northern cultural activity, contemporary ethnic music is conceived here as a strategic tool with which stereotypes of northernness can be contested and the work of the preservation of ethnic heritage put into action. The focus is on the works of Inari Sámi-singing rap musician Amoc, Skolt Sámi-singing heavy rock girl Tiina Sanila and the North Sámi-singing hard rock band SomBy. Their music is approached as ‘singing acts’ that work as tools for the preservation of ethnic culture and minority languages and for the deconstruction of stereotypes directed at northernness. The paper claims that contemporary contexts and genres within which singing in Sámi languages takes place may inspire the audience to ponder and reconsider their own ways of perceiving Sáminess and northernness.     

W(h)ither the academy? An exploration of the role of university social work in shaping the future of social work in Europe

A controversial proposal to pilot the training of child protection social workers through an intensive work-based route in England is being supported and funded by the UK Government. Frontline, the brainchild of a former teacher, locates social work training within local authorities (‘the agency’) rather than university social work departments (‘the academy’) and has stimulated debate amongst social work academics about their role in shaping the direction of the profession. As a contribution to this debate, this paper explores the duality of social work education, which derives its knowledge from both the academic social sciences and the experience of practice within social work agencies. While social work education has traditionally been delivered by the academy, this paper also explores whether the delivery of training in the allied professions of probation and nursing by ‘the agency’ is equally effective. Finally, this paper explores the Helsinki model which achieves a synergy of ‘academy’ and ‘agency’. It suggests that there are alternative models of social work education, practice and research which avoid dichotomies between the ‘academy’ and the ‘agency’ and enable the profession to be shaped by both social work academics and practitioners.     

Articulations of populism: the Nordic case

Populism as a concept is elusive and has been connected to very different political movements. Generally, populism’s connotations are rather negative and the term is often used pejoratively in the academic field as well. However, Ernesto Laclau has approached populism by arguing that populist reason is a manifestation of political logic in which group identification – formed through various signifiers such as ‘the people’, which are articulated as part of an ‘equivalence chain’ – eventually establishes political agency as a totality. This paper uses Laclau’s articulation theory to analyse the public construction of contemporary populism in the Nordic countries of Sweden, Finland, Norway and Denmark. The analysis demonstrates that mainstream media frame populism rather negatively, although examples of the term’s positive identification with ‘the people’ are available, especially in the tabloid media. Thus, the positive identification behind the forming of populist movements clashes with the media discourse that prioritizes established journalistic views, practices and sources, making populism a ‘floating signifier’, that is, a concept that has several meanings which are contested in various public discourses. A general pattern in the construction of populism in Northern European multi-party democracies can be discerned, thus identifying the central role of nationalist and nativist identifications in contingent populist articulations. However, the differences between the Nordic countries emphasize a context-driven approach.     

Effect of aggregation on the estimation of trend in mortality

There are three approaches to analyzing and forecasting age‐specific mortality: (1) analyze age‐specific data directly, (2) analyze each cause‐specific mortality series separately and add the results, (3) analyze cause‐specific mortality series jointly and add the results. We show that if linear models are used for cause‐specific mortality, then the three approaches often give close results even when cause‐specific series are correlated. This result holds for cross‐correlations arising from random misclassification of deaths by cause, and also for certain patterns of systematic misclassification. It need not hold, if one or more causes serve as “leading indicators”; for the remaining causes, or if outside information is incorporated into forecasting either through expert judgment or formal statistical modeling. Under highly nonlinear models or in the presence of modeling error the result may also fail. The results are illustrated with U.S. age‐specific mortality data from 1968–1985. In some cases the aggregate forecasts appear to be the more credible ones.     

Leg-extension strength and chair-rise performance in elderly women with Parkinson's disease

The lower extremity performance in elderly female patients with mild to moderate Parkinson's disease (PD; n = 12) and controls (n = 16) was compared. Isometric dynamometry and force-plate measurements were used. PD patients had lower (p < .05) bilateral (BL) maximal isometric leg-extension force (MF), BL isometric MF relative to body mass, and maximal rate of isometric force development than control participants. BL strength deficit was greater (p < .05) in PD patients than in controls. A significantly longer chair-rise time and lower maximal rate of vertical-ground-reaction-force development while rising from a chair was found in PD patients than in controls. These findings suggest that elderly women with PD have lowered voluntary isometric force-generation capacity of the leg-extensor muscles. Reduced BL leg-extension strength might contribute to the difficulty of individuals with PD to rise from a chair.     

When Disciplinary Worlds Collide: The Organizational Ecology of Disciplines in a University Department

This study draws from the social world perspective to examine the relationships between scientific disciplines (i.e., molecular biology, plant physiology, agronomy, horticulture, and agroecology) at a university department in the field of plant production research. The interview data obtained in the study revealed that the complex organizational ecology of disciplines in the department involved four sources of conflict: (1) a challenge of the established departmental research tradition of agronomy, (2) a struggle over working space, (3) the extension into the department of an ethical‐ideological controversy over genetically modified organisms, and (4) the anchoring of disciplines to different organizational units of the university. Thus, instead of facilitating the synergistic potential of the disciplines, the organizational arrangements at the university blocked it. From this perspective, the study challenges, but does not refute, previous symbolic interactionist research by suggesting that conflicts may function as valuable analytic devices in revealing how formal organizational structures hinder the achievement of social order at the working level.     

A Method for Measuring Distance From a Training Data Set

A new method is proposed for measuring the distance between a training data set and a single, new observation. The novel distance measure reflects the expected squared prediction error when a quantitative response variable is predicted on the basis of the training data set using the distance weighted k-nearest-neighbor method. The simulation presented here shows that the distance measure correlates well with the true expected squared prediction error in practice. The distance measure can be applied, for example, in assessing the uncertainty of prediction.
