A seasonal mixed-POT model to estimate high flood quantiles from different event types and seasons

Flood events can be caused by several different meteorological circumstances. For example, heavy rain events often lead to short flood events with high peaks, whereas snowmelt normally results in events of very long duration with a high volume. Both event types have to be considered in the design of flood protection systems. Unfortunately, all these different event types are often included in annual maximum series (AMS) leading to inhomogeneous samples. Moreover, certain event types are underrepresented in the AMS. This is especially unsatisfactory if the most extreme events result from such an event type. Therefore, monthly maximum data are used to enlarge the information spectrum on the different event types. Of course, not all events can be included in the flood statistics because not every monthly maximum can be declared as a flood. To take this into account, a mixture Peak-over-threshold model is applied, with thresholds specifying flood events of several types that occur in a season of the year. This model is then extended to cover the seasonal type of the data. The applicability is shown in a German case study, where the impact of the single event types in different parts of a year is evaluated.     

An Empirical Analysis of the Amount of Publication Fees

Among the financing strategies available for Open Access (OA), the author-pays business model has received increasing attention. The consequences of this approach, however, for the system of scholarly communication and for publishing houses as participants in value added, have remained largely unclear. The paper presented here, therefore, analyzes the probable realistic magnitude of publishing fees in different subjects, based on empirical data. The paper shows that the most favorable conditions are met in the Natural Sciences and in Mathematics. However, the analysis also shows that publishing houses would have to raise publishing fees well beyond the level that scientists are willing to pay. Furthermore, the analysis leads to the conclusion that the amount of money currently available in the system of scholarly communication is probably not sufficient for the sustainable financing of publishing fees.     

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.     

Involving Young Disabled People in the Research Process: The Experiences of the PIE Research Project Team

Young disabled people are still rarely involved in the research process, despite an increasing emphasis on their inclusion as participants. The Participation in Education (PIE) project examined how disabled children with little or no speech could be involved in their education. The project team worked with an existing group of young disabled people to develop ways in which they could take part in the research process. The group was involved in developing the methodology, group work, observation, commenting on findings and in the dissemination process. Their involvement undoubtedly enriched the research and the benefits of working with an established group were manifold.

The Politics of ‘Social Accountability’ in England and Germany: Democratic Control and Moral Imperatives

This article investigates how politicians in England and Germany approach social accountability during the introduction of markets in the national health care systems. It analyses the discourse among members of parliament during the law making process of the 2012 NHS Health Care Act in England and the 2011 Act for Financing of Statutory Health Insurance in Germany. Generally, the new social accountability reform agenda is attractive to policy makers as it foregrounds public engagement and bottom-up participation (Peters 2001). Social accountability refers to institutional practices that favour participatory and horizontal mechanisms that depart from traditional hierarchical Principal-Agent forms.     

Child Protection in Voluntary Sports Clubs in Germany — Factors Fostering Engagement in the Prevention of Sexual Violence

Based on the theoretical framework of organisational capacity and using data from an online survey of 8571 sports clubs in Germany, this study investigates clubs’ engagement towards child protection and the prevention of sexual violence. Only half of the clubs indicate that the prevention of sexual violence is a relevant topic for them, and on average, the clubs have implemented between two and three prevention measures. Pertaining to organisational capacity, human resource capacity (e.g. share of volunteers, share of women on the board) and structural capacity (e.g. club culture) exhibit significant effects on clubs’ activation towards child protection.     

Voluntary Work‐related Technology Use during Non‐work Time: A Narrative Synthesis of Empirical Research and Research Agenda

The Internet and mobilization of information and communication technologies (ICTs) have made non‐manual work increasingly portable and remotely accessible. As a result, a considerable number of employees use their ICTs to engage in work‐related tasks during designated non‐work time, even without contractual obligation. However, existing research on such voluntary work‐related ICT use remains fragmented and spread across disciplines. The authors conducted a narrative review of 56 studies to identify themes in existing research, synthesize the evidence base and identify gaps in understanding. They identify five themes: (1) Social‐normative organizational context, (2) Job‐related characteristics and work processes, (3) Person characteristics, (4) Designated non‐work time and well‐being, and (5) Empowerment/Enslavement Paradox. A conceptual model of voluntary ICT use is developed by integrating the identified themes with existing organizational research, outlining the relationships between the identified themes and voluntary ICT use. The discussion emphasizes the need for more conceptual clarity on voluntary ICT use and related constructs, and for the integration of different disciplines and methodological approaches to advance knowledge in the field. The authors further identify person‐centred research as a critical future avenue to explore different ICT user types. Additionally, more research into the mechanisms and moderating influences regarding voluntary ICT use and its outcomes is considered advisable to advance knowledge on the Empowerment/Enslavement Paradox and its potential resolution. The paper concludes with preliminary implications to inform practice, addressing the need for employers to provide control over voluntary ICT use and employees enacting this control.
