Frequentist and Bayesian approaches for a joint model for prostate cancer risk and longitudinal prostate-specific antigen data
2015
The paper describes the use of frequentist and Bayesian shared-parameter joint models of longitudinal measurements of prostate-specific antigen (PSA) and the risk of prostate cancer (PCa). The motivating dataset corresponds to the screening arm of the Spanish branch of the European Randomized Screening for Prostate Cancer study. The results show that PSA is highly associated with the risk of being diagnosed with PCa and that there is an age-varying effect of PSA on PCa risk. Both the frequentist and Bayesian paradigms produced very close parameter estimates and subsequent 95% confidence and credibility intervals. Dynamic estimations of disease-free probabilities obtained using Bayesian infe…
Sticking with your university: the importance of satisfaction, trust, image, and shared values
2016
In a context of increasing competition and financial difficulties for higher education institutions, alumni loyalty is a key factor for survival and success. This study tests a model derived from a relationship marketing perspective to investigate the roles of four variables (brand image, trust, satisfaction, and shared values) in the direct and indirect explanation of alumni loyalty. Based on a literature review, a theoretical model is proposed and tested through structural equations modeling for a sample of 1000 university alumni. The results reveal three direct antecedents of alumni loyalty (satisfaction, shared values, and trust) and one indirect antecedent (university brand image). In …
Indicators of improved learning contexts : a collaborative perspective on educational leadership
2015
The aim of this paper is to illustrate indicators for improved learning contexts based on the notion of collaborative leadership. Collaborative leadership refers to synergetic educational leadership practices through co-performance and a continuous and shared learning process. We argue that the indicators could serve as a bridge between education and the complex and increasing change within the social life and world of work. For finding the indicators, we combined two intertwining dimensions: ‘leadership in education’ and ‘education for leadership’. They were studied by a tested model describing collaborative leadership by a set of attributes. We then applied these attributes to a curriculu…
Symbolic leadership and leadership culture in one unified comprehensive school in Finland
2012
The research presented in this article is a description of the symbolic leadership and leadership culture in one unified comprehensive school in Finland. The study is a phenomenological qualitative case study based on triangulation. Leadership is studied through its functional, verbal and material dimensions. Leadership culture is regarded as one of the part cultures of the organisation culture. It is a product of the meaning and interpretation process which forms itself through the symbols of the principal's leadership. According to the present study, the leadership culture of the unified comprehensive school can be described as consisting of respect, communality, equality and humour.
Sustainability in executive remuneration : A missing link towards more sustainable firms?
2021
This paper contributes by showing simultaneously the interlinked challenges of sustainability-based (based on long-term economic, social and environmental targets) executive remuneration and the problems of transparency in remuneration reporting. Our empirical data, analyzed using qualitative content analysis, consists of the published remuneration statements and sustainability reports of 43 Finnish companies reporting according to the Global Reporting Initiative (GRI) framework. Our results indicate that comprehensive sustainability remuneration is still rare in Finnish large companies: long-term financial targets are implemented at most companies, but social or environmental targets were …
Sampling Design in SHARE Wave 8 and Recruitment of Refreshment Samples until the Suspension of Fieldwork
2022
The aim of the SHARE survey design is to be able to draw inferences about the population of people aged 50 years or older across countries by using probability-based sampling. This chapter documents the sampling design adopted in the eighth wave of SHARE that had to be suspended due to COVID-19 in March 2020. Starting with a definition of the SHARE target population, we describe the protocol for harmonizing and documenting the sampling procedure and present the sampling frames used by the countries that recruited a baseline or refreshment sample in Wave 8. We then discuss some important aspects of the SHARE sampling designs, such as stratification, clustering, variation in selection probabi…
Empowering team leadership and safety performance in nuclear power plants: A multilevel approach
2013
Abstract Despite the large body of work on team leadership, hardly any literature has dealt with team leadership in safety performance settings. The goal of the present study is to analyze how team leader behaviors influence team members’ safety performance in nuclear power plants. For this purpose, an empowering leadership approach was assessed. We consider a multilevel model in which safety performance is divided into three types of behaviors. The sample was composed of 479 workers in 54 groups from two Spanish nuclear power plants. The results suggested that leaders’ empowering behaviors generated higher safety compliance behaviors and higher safety participation behaviors by team member…
Leadership in an online multiplayer strategy game: case – Illuria
2011
This paper looks at leadership communication in the context of online multiplayer games and the groups that operate within them. In multiplayer games promoting teamwork and long-term cooperation, issues of management and leadership are prevalent. The study explores the experiences that members of multiplayer communities have towards leadership in multiplayer games by looking at one specific case of organised team play within the framework of a turn-based online strategy game. The data utilised in this study consist of themed player interviews conducted via e-mail. The analysis proposes three central dimensions that emerged from the data. These were labelled: (1) the leader as primus motor, …
Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali
2019
I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…
Parallel Collision Queries on the GPU
2013
We present parallel algorithms to accelerate collision tests of rigid body objects for a high number of independent transformations as they occur in sampling-based motion planning and path validation problems. We compare various GPU approaches with a different level of parallelism against each other and against a parallel CPU implementation. Our algorithms require no sophisticated load balancing schemes. They make no assumption on the distribution of the input transformations and require no pre-processing. Yet, we can perform up to 1 million collision tests per second with our best GPU implementation in our benchmarks. This is about 2.5X faster than our reference multi-core CPU implementati…
