The Monetary Value of Voluntary Work: Conceptual and Empirical Comparisons

The purpose of this article is to provide a comprehensive comparison of different valuation approaches for estimating the monetary value of voluntary work both conceptually and empirically. This study adds to the literature by suggesting two approaches: (1) the leisure-adjusted opportunity cost approach (OCA), which corrects for voluntary work being a leisure substitute, is suggested as an alternative to the alternative-employment wage approach (AEWA). And (2) the volunteer judgment replacement wage approach (RWA), where volunteers state a wage rate that they consider adequate for the task they perform, is suggested as an alternative to the generic RWA. Using data on volunteers in German non-profit sports clubs (n = 566), the valuations show that the monetary value of 1 h of voluntary work is highest for the generic RWA (€14.27), followed by the AEWA (€14.03), the volunteer judgment RWA (€9.98), and the leisure-adjusted OCA (€1.78).

     

Socio-economic patterns of sport demand and ageing

Due to the demographic situation in nowadays societies, physical activity, and sport expenditure have to be analysed from a demographic as well as socio-economical perspective. This means that determinants such as age, gender, nationality/ethnicity, income, time, educational level, profession, and social status have to be taken into account. However, when comparing the various studies, the different methods of analysis and different operationalisation of variables have to be considered. This is in particular vital investigating age. Whilst cross-sectional studies point out that physical activity generally decreases with increasing age, longitudinal analyses come to different results. Previous studies indicate that pertaining to gender more men take part in sports than women. However, considering period and cohort effects, recent longitudinal studies showed that women participate more in sport than in the past. Besides, it was found out that men generally tend to spend more money on sports than women do. A further finding is that the educational level influences physical activity positively. Research revealed that income had a positive impact on both, physical activity and sport expenditure.     

How an aging society affects the economic costs of inactivity in Germany: empirical evidence and projections

Background

Aging societies represent a major challenge for health care systems all over the world. As older people tend to be more physically inactive, economic costs of inactivity are likely to increase notably. The present study aims to investigate this relationship between an aging society and economic costs of inactivity using the example of Germany.

Methods

Using data from the German Socio-Economic Panel, this study applied the comparative risk assessment method developed by the WHO to estimate the direct costs of inactivity for the period 2001–2013 differentiated by gender-specific age-groups (15–29; 30–44; 45–64; 65+). Based on population statistics predicting the aging of the German population for the years 2014–2060, this research projects the development of future costs of inactivity and potential effects of interventions promoting physical activity among the German population.

Results

The results reveal an increase in the level of physical activity during the observed period (2001–2013) which compensated the negative effect of aging and resulted in a decline of inactivity costs. The projections for the years 2014–2060 indicate a constant increase in direct per capita costs until 2060 because of an aging society. Scenarios indicating how a short-term reduction of physical inactivity impacts costs of inactivity reveal the crucial role of the oldest age-group in this context.

Conclusion

The findings indicate that the aging of the German population demands further actions and initiatives to promote physical activity, especially for the oldest age-group.

     

Recruitment and Retention of Referees in Nonprofit Sport Organizations: The Trickle-Down Effect of Role Models

The recruitment and retention of voluntary referees is challenging for nonprofit sport organizations. This study examines the trickle-down effect of role models on the retention of already active referees and the recruitment of new referees in German football (soccer). Secondary panel data on the number of referees and role models (i.e., referees promoted to the status of a Bundesliga or FIFA referee) were collected for the 21 regional football associations. The regression results show that the presence of role models has a statistically significant and positive effect on the number of existing referees. The number of new referees is positively affected by referees who were promoted to the status of a first Bundesliga referee, but not by those promoted to the status of a FIFA referee. The findings suggest that nonprofit sport organizations should capitalize on the effect of role models to a greater extent.     

Examining the Financial Condition of Sport Governing Bodies: The Effects of Revenue Diversification and Organizational Success Factors

Sport governing bodies play a critical role in the sport system. The purpose of this study is to analyze their financial condition, a topic that has been largely neglected in previous research. Based on financial portfolio theory, it was suggested that the level of revenue diversification has a positive effect on their financial condition (measured through total revenues, break even, profit, and investments). Also, the influence of sport-related and financial success factors was examined using data from a nationwide online survey of sport governing bodies in Germany (n = 1,080). The results provided evidence of a relatively high level of revenue diversification compared with other industries. Revenue diversification, hosting major sporting events, and cost optimization had a positive effect on the financial condition, while increasing memberships in clubs and organizing competitions had a negative influence. The findings have implications for the management of sport governing bodies.     

Penalized multidimensional fitting for protein movement detection

The three-dimensional structure of a given protein can take different conformations depending upon the reaction it undergoes and its substrate/cofactor/partners binding state. Various methods exist to study these conformational changes but only one, called DynDom, is clearly focused on movement detection. An alternative method is proposed, making use of multivariate data analysis, called ‘penalized Multidimensional Fitting (penalized MDF)’ based on penalized movements of points in order to approach the distances between points after movement to the distances given by the reference matrix. The objective is to detect the amino acids that undergo an important movement by fitting the distances of one conformation to the distances of the second one by modifying only the coordinates of the first one. This method is applied to three different proteins.     

Perfect sampling algorithm for small <Emphasis Type="Italic">m</Emphasis>×<Emphasis Type="Italic">n</Emphasis> contingency tables

A Markov chain is proposed that uses coupling from the past sampling algorithm for sampling m×n contingency tables. This method is an extension of the one proposed by Kijima and Matsui (Rand. Struct. Alg., 29:243–256, 2006). It is not polynomial, as it is based upon a recursion, and includes a rejection phase but can be used for practical purposes on small contingency tables as illustrated in a classical 4×4 example.     

Understanding the Importance of Organizational Resources to Explain Organizational Problems: Evidence from Nonprofit Sport Clubs in Germany

Nonprofit sport clubs experience organizational problems regarding the recruitment and retention of members, volunteers, and coaches, and the financial situation of the club. The purpose of this study is to investigate the impact of different types of organizational resources on the severity of organizational problems. A theoretical framework based on the concept of organizational capacity is presented, which explains the influence of human, financial, infrastructure, and cultural resources on organizational problems. The empirical evaluation is undertaken using data from a nationwide online survey of nonprofit sport clubs in Germany (n = 19,345). The regression results show that human resources (women on the board, secondary volunteers, etc.), financial resources (Herfindahl index), infrastructure resources (own facilities, and public facilities), and cultural resources (e.g., strategic policy, formation policy, value of conviviality, and variety of sports) are significant determinants of organizational problems. The findings of this study have implications for the management of voluntary sport organizations.
