A non-parametric regression approach to repeated measures analysis in cancer experiments

The validity conditions for univariate or multivariate analyses of repeated measures are highly sensitive to the usual assumptions. In cancer experiments, the data are frequently heteroscedastic and strongly correlated with time, and standard analyses do not perform well. Alternative non-parametric approaches can contribute to an analysis of these longitudinal data. This paper describes a method for such situations, using the results from a comparative experiment in which tumour volume is evaluated over time. First, we apply the non-parametric approach proposed by Raz in constructing a randomization Ftest for comparing treatments. A local polynomial fit is conducted to estimate the growth curves and confidence intervals for each treatment. Finally, this technique is used to estimate the velocity of tumour growth.     

Behavioural determinants of perceived managerial and leadership effectiveness in Argentina

The purpose of this empirical study was to explore the perceptions of Argentinean managers and non-managerial employees about managerial and leadership effectiveness, and the extent to which the findings are generalized to other countries. The central research question addressed was as follows: How do people employed in Argentinean companies behaviourally distinguish effective managers from ineffective managers, and to what extent are the findings culture-specific or context-general? A total of 42 employees from private and public sector organizations in Cordoba, Argentina, were interviewed using critical incident technique. The interviews generated 302 critical incidents of which 155 were examples of positive (effective) managerial behaviour, and 147 of negative (ineffective) managerial behaviour. The findings suggest that Argentineans perceive as effective those managers who are supportive, considerate, motivating, caring, good decision makers, approachable, participative, fair-minded, communicative, actively involved, and who act as role models. This challenges the widely held belief that Argentineans prefer authoritarian managers over democratic ones.     

Indicators of a balanced long-term service and support system: examining the impact on individuals aging with a lifelong disability

This article explores how rebalancing efforts can support the needs of individuals aging with a lifelong disability. The National Balancing Indicator project examined the overall long-term supports and services system (LTSS) progress in five indicators within the Sustainability, Coordination and Transparency, and Prevention principles toward a balanced LTSS system for those aging with a lifelong disability. In assessing state efforts to create a balanced participant-directed LTSS system with the National Balancing Indicators, the findings suggest states are better equipping the system to handle a burgeoning population of individuals aging with a lifelong disability, but more progress is still needed. Overall, states need to continue to create a seamless system that allows individuals with lifelong disabilities to transition smoothly through the life course.     

Buying membership in the transnational community:migrant remittances,social status,and assimilation

I analyze the effects that social status and immigrant incorporation have on migrant remittances. Understanding remittances as one type of transnational practice, I conceptualize them as the fee that migrants pay to remain members of the transnational community. I define a “status hypothesis” in terms consistent with the view of transnational engagement as a response to status loss, predicting a negative association between increases in social status and remittances. Since immigrant incorporation usually entails status gain, this hypothesis is consistent with the conventional assimilation paradigm. While the status hypothesis could be linked to the new economics of labor migration as well, it collides with the view of transnationalism as an alternative path for successful immigrant incorporation. Using data on male Mexican migrants to the United States, I find enough support for the status hypothesis, indicating the need to clarify the ultimate meaning of transnational practices. In addition, my analysis shows that there is room to integrate economic theory, the assimilation paradigm, and the transnational perspective into a comprehensive understanding of transnational engagement.     

Managerial and leadership effectiveness as perceived by managers and non-managerial employees in Mexico

Using the critical incident (CI) technique, concrete examples of effective and ineffective managerial behaviour (CIs) were collected from managers and non-managerial employees within private and public sector organizations situated in the north and southeast regions of Mexico. The CIs were content analysed using open, axial and selective coding to identify a smaller number of thematic categories. A total of 38 ‘manager’ and 35 ‘non-managerial employee’ behavioural categories were identified respectively, of which 82.19% (n = 60) were found to be either convergent or polar opposite in meaning. The findings suggest that what behaviourally differentiates effective managers from ineffective managers is perceived, described and defined by Mexican managers and non-managerial employees in much the same way. The study provides new insights on the issue of perceived managerial and leadership effectiveness in Mexico and is a rare example of indigenous managerial behaviour research in a non-Anglo country.     

‘Look at What We Made’: communicating subcultural value on London’s Southbank

ABSTRACT

This article sets out key findings of an interdisciplinary Arts and Humanities Research Council (AHRC) funded project that uses Long Live Southbank’s (LLSB) successful campaign to retain London’s Southbank Undercroft for subcultural use – skateboarding, BMXing, graffiti art, etc. – as a case study to generate discussions about young people’s experiences and engagements with (sub)cultural heritage and political activism. At the heart of this inquiry is the perceived contradiction between the communicative practices of subcultures and social protest movements: the former typically understood to be internally oriented and marked by strong boundary maintenance, and the latter, to be successful, to be externally oriented to a diverse range of publics. In explaining the skaters/campaigner’s negotiation of this contradiction, we look to the inclusive and everyday concepts of ‘inhabitant knowledge’ [Ingold, T., 2000 Ingold, T., 2007. Lines: a brief history. London: Routledge.[Crossref] , [Google Scholar]. The perception of the environment: essays in livelihood, dwelling and skill. London: Routledge], ‘vernacular creativity’ [Burgess, J., 2009. Remediating vernacular creativity: photography and cultural citizenship in the Flickr photosharing network. In: T. Edensor, D. Leslie, S. Millington, and N. Rantisi, eds. Spaces of vernacular creativity: rethinking the cultural economy. London: Routledge, 116–126] and ‘affective intelligence’ [Van Zoonen, L., 2004. Imagining the fan democracy. European journal of communication, 19 (1), 39–52]. In eschewing the exclusionary and contestatory language of (post)subcultural and spatial theories, this article proposes new frameworks for thinking about the political nature of young people’s bodily knowledge and experiences, and the implications of this for the communication of (sub)cultural value.     

Knowledge management in product innovation: an interpretative review

Knowledge management (KM) is relatively new, but still a very hot topic in management research and practice. Leading companies are reshaping their organizations in order to increase their ability in managing knowledge sharing and transfer within and across their organizational boundaries. KM is today considered by many scholars the next arena for global competition. Product innovation (PI), in particular, is one of the most promising areas, where KM is today applied and studied. Management literature has underlined how knowledge becomes the only source of sustainable competitive advantage in turbulent contexts, and the cognitive perspective represents the most adequate approach to analysing and understanding PI as a continuous learning process rather than as a sporadic event. Since the early 1990s, many contributions emerged from different fields, but after nearly one decade, KM is not yet a unitary stream of literature but reflects very diverse roots. In this paper, the different streams and approaches emerging in literature on KM in PI are reviewed and described, aiming at providing researchers with an interpretative tool and some directions for further research.
