Effects of the COVID-19 Pandemic on Sports Entrepreneurship
2020
Sports entrepreneurship has been considered an important part of sports organisations when overcoming crisis situations. The aim of this study is to determine the impact of the crisis derived from COVID-19 on sports entrepreneurship and whether there are differences in the prediction of entrepreneurship on service quality in non-profit sports clubs. To this end, 145 sports clubs were analysed before and after the outbreak of the virus in society. Paired sample-t tests were carried out to determine the differences in variables studied before (Time I) and after (Time II) the COVID-19 outbreak, and correlations and hierarchical linear regressions were used to analyse the relationship between t…
The Interactions between COVID-19 Cases in the USA, the VIX Index and Major Stock Markets
2021
With this study, we aimed to determine (1) the effect of the daily new cases and deaths due to the COVID-19 pandemic in the United States on the CBOE volatility index (VIX index) and (2) the effect of the VIX index on the major stock markets during the early stage of the pandemic period. To do this, we collected and analysed the daily new cases and death numbers during the COVID-19 pandemic period in the United States and the country indexes of the USA (DJI), Germany (DAX), France (CAC40), England (FTSE100), Italy (MIB), China (SSEC) and Japan (Nikkei225) to determine the impact of the VIX index on the major stock markets. We then subjected this data to the Johansen co-integration test and …
Accentuating the Interrelation between Consumer Intention and Healthy Packaged Food Selection during COVID-19: A Case Study of Pakistan
2021
This study contemplates the factors that influence consumer intention, before and during the eruption of COVID-19, for the selection of healthy packaged food in Pakistan. The extant studies have identified two distinct attitudes of consumers about food label information: one is its usefulness and the second elucidates the avoidance. Hence forth, the current study contributes to the extant literature while signifying both reasons which motivate consumers to read food labels and reasons which discourage consumers from consult food labels at the point of purchase. Moreover, the impact of subjective norms and self-efficacy for healthy packaged food intentions has also been examined for both bef…
Special Issue: "The Latest Clinical Advances in Thrombocytopenia"
2021
Platelets are critical elements in the blood stream, supporting hemostasis as well as performing even more complex tasks within networks of biological (immunity) and pathophysiological processes, such as cancer and ischemia/reperfusion injury [...]
Exosome levels in human body fluids: A tumor marker by themselves?
2016
Despite considerable research efforts, the finding of reliable tumor biomarkers remains challenging and unresolved. In recent years a novel diagnostic biomedical tool with high potential has been identified in extracellular nanovesicles or exosomes. They are released by the majority of the cells and contain detailed molecular information on the cell of origin including tumor hallmarks. Exosomes can be isolated from easy accessible body fluids, and most importantly, they can provide several biomarkers, with different levels of specificity. Recent clinical evidence shows that the levels of exosomes released into body fluids may themselves represent a predictive/diagnostic of tumors, discrimin…
Employment trajectories until midlife associate with early social role investments and current work-related well-being
2021
Applying social investment theory (SIT), we examined whether employment trajectories until midlife, with differential investments in education and employment, are associated with social investments during early life and with work-related well-being in midlife, with a special reference to potential differences between self-employment and paid work. In the Northern Finland Birth Cohort 1966 (n = 6496; 2963 men, 3533 women), life-history calendars from age 16 to 45 were used to determine the respondents’ yearly employment statuses (student, full-time employee, part-time employee, self-employed, unemployed, on parental leave, on sabbatical leave or otherwise not working). Latent class analysis …
Biofilia en el centro comercial: atracción del ambiente de naturaleza y su efecto sobre la imagen, los estados afectivos y el comportamiento de los v…
2018
Se realizo una tesis en modalidad de compendio de cuatro artículos enfocados en analizar la capacidad de atracción del “ambiente eco-natural / de naturaleza / biofílico” de los centros comerciales a través del examen de sus efectos específicos sobre las respuestas afectivas, cognitivas y de comportamiento de los visitantes. El primer articulo se enfoca en explorar la imagen de los centros comerciales siguiendo un método lexicométrico. Esta técnica permite examinar la capacidad de atracción revelando principales motivaciones de visita, y contrastándolas frente a variables personales como género, nivel socioeconómico y tipo de percepción (favorable o desfavorable). La segunda investigación y …
On the stability of some controlled Markov chains and its applications to stochastic approximation with Markovian dynamic
2015
We develop a practical approach to establish the stability, that is, the recurrence in a given set, of a large class of controlled Markov chains. These processes arise in various areas of applied science and encompass important numerical methods. We show in particular how individual Lyapunov functions and associated drift conditions for the parametrized family of Markov transition probabilities and the parameter update can be combined to form Lyapunov functions for the joint process, leading to the proof of the desired stability property. Of particular interest is the fact that the approach applies even in situations where the two components of the process present a time-scale separation, w…
Coupled conditional backward sampling particle filter
2020
The conditional particle filter (CPF) is a promising algorithm for general hidden Markov model smoothing. Empirical evidence suggests that the variant of CPF with backward sampling (CBPF) performs well even with long time series. Previous theoretical results have not been able to demonstrate the improvement brought by backward sampling, whereas we provide rates showing that CBPF can remain effective with a fixed number of particles independent of the time horizon. Our result is based on analysis of a new coupling of two CBPFs, the coupled conditional backward sampling particle filter (CCBPF). We show that CCBPF has good stability properties in the sense that with fixed number of particles, …
Are Intercultural Competences at the Center of Job-Market Demands ?
2020
International audience; This chapter introduces the theoretical framework upon which this study was based before going on to set out the methodology used and detail the main results found. It discusses results in the light of scientific literature on the issue and their managerial implications. With the internationalization of organizational structures, the development of intercultural competences was often considered a strategic benefit. Indeed, companies are sensitive to the cultural diversity of their worldwide branches and to the international competences developed by their employees. Through organizational internationalization, intercultural competences become strategic resources. Alth…
