About 50 y ago, Crow and Kimura [An Introduction to Population Genetics Theory (1970)] and Ohta and Kimura [Genet. Res. 22, 201–204 (1973)] laid the foundations of conservation genetics by predicting the relationship between population size and genetic marker diversity. This work sparked an enormous research effort investigating the importance of population dynamics, in particular small population size, for population mean performance, population viability, and evolutionary potential. In light of a recent perspective [J. C. Teixeira, C. D. Huber, Proc. Natl. Acad. Sci. U.S.A. 118, 10 (2021)] that challenges some fundamental assumptions in conservation genetics, it is timely to summarize what the field has achieved, what robust patterns have emerged, and worthwhile future research directions. We consider theory and methodological breakthroughs that have helped management, and we outline some fundamental and applied challenges for conservation genetics.

Personal digital collections systems, which encourage visitors to museum websites to create their own personal collections out of a museum’s online collections, are the latest trend in personalization technologies for museums and other cultural heritage organizations. This chapter explores the development, implementation, and evaluation of different types of personal digital collection interfaces on museum websites, from simple bookmarking applications to sophisticated tools that support high levels of interactivity and the sharing of collections. It examines the potential impact of these interfaces on the relationship between museums and their online visitors, explores the possible benefits of involving users as co-creators of digital cultural heritage, and offers an analysis of future research directions and best practices for system design, presenting lessons learned from more than a decade of design and development of personal digital collections systems on museum websites.

The aim of the chapter is to present the concept of downsizing from different points of view: as a strategic option, as a management tool and as a phenomenon. It describes the evolution of the term, its definitions, and different directions of development. A scale and possible outcomes are described on the basis of financial analysis; however it also discusses the role of non-financial aspects. The chapter points out reasons, aims and a wide range of tools that may be used during implementation of downsizing. One of the conclusions of the chapter is to present future research directions aiming at increasing knowledge of managers and providing them with detailed good practices.

This chapter reviews the major methodological and theoretical approaches used in Mining Language, at once concluding the book and gesturing toward future research directions in the fields of history of colonial science and technology and Indigenous Studies. Specifically, it reflects on the relationship between history and literary studies within these intersecting fields. By reflecting on what colonial archives say and do not say, the conclusion argues for the importance of research ethics and methods that confront, acknowledge, and respond to historical silences.

To examine the relationship between the Protestant work ethic (PWE) and the need for cognition (NFC), 210 Americans completed the Mirels and Garrett (1971) PWE scale and the Cacioppo, Petty, and Kao (1984) NFC scale. Although there was no relationship between the composite PWE scale and NFC, there were relationships between two of three PWE factors and NFC. Specifically, correlational analyses revealed that the PWE factor of hard work as a means to success was negatively related to NFC, whereas the PWE factor of antileisure was positively related to NFC. Results are discussed with respect to the multidimensional structure of various PWE measures. Issues concerning the multifaceted nature of the PWE and future research directions are also considered.

Spectator motives have been conventionally used to explain sport spectator behavior, such as word-of-mouth recommendations and revisit intention. A review of the literature suggests that the predictability of spectator motives is both inconsistent and context dependent. We proposed that these factors can be reconciled by directly examining the role of spectator well-being in the relationship between spectator motives and repatronage behavior. Our findings revealed that spectator well-being significantly mediates the effects of 5 motives, that is, achievement, aesthetics, knowledge, family, and escape, on sport spectator revisit intention and word-of-mouth recommendations. Future research directions are also discussed.

This article is a critical review of studies concerning the relationship of parental warmth and hostility to sex-related differences in children's achievement orientation. Parental warmth seemed to operate differently upon girls' and boys' achievement orientation in most of the studies cited. Moderate but not high maternal warmth and even slight hostility were related to strong achievement∗ orientation in girls, while high maternal nurturance and affection were associated with strong achievement orientation in boys. However, the article warns against assuming a simple causal relationship between parental warmth and sex-related differences in children's achievement orientation. Achievement theories, two main parental dimensions, and future research directions are also discussed.

While most of the existing research on religion and volunteering has been conducted in Western, predominantly Christian settings, how religion and volunteering are related in non-Western, non-Christian societies have not yet been sufficiently studied. Recently more and more researchers are becoming more interested in religion and volunteering in Taiwan and are conducting case studies on the Tzu Chi Association. However, the relationship between multi-dimensional religiosity and volunteering in Taiwan has not yet been examined. This study attempts to contribute to this literature by analysing one of the most extensive sampling surveys in Taiwan. I found that (1) various kinds of religiosity in Taiwan, other than belonging to Buddhist organisations, have different effects on both religious and secular volunteering; (2) religious volunteering and secular volunteering were different with respect to their correlation with multi-dimensional religiosity; (3) religious participation is a significant factor in promoting respondent’s religious volunteering but it is not a significant factor on respondent’s secular volunteering; (4) some religiosities, such as belief in spirits and karmic charity, are negative determinants of volunteering; and (5) spiritual behaviour is a significant and positive determinant of both religious volunteering and secular volunteering. In addition, the implications and future research directions are discussed.

The current study aims at examining the relationship between the perfectionism two-factor model (i.e., concerns and strivings) and burnout dimensions measured by using the BAT (Burnout Assessment Tool) through a longitudinal study. A two-wave cross-lagged study was conducted using path analysis in SEM (Structural Equation Modeling) of 191 workers. Results confirmed the predictive role of perfectionistic concerns on the burnout dimensions, whereas perfectionistic strivings were not significantly related, suggesting that perfectionism should be monitored by employers and clinicians to prevent employee burnout. Limitations and future research directions are envisaged.

Abstract. This paper provides a state-of-art account on flood vulnerability indices, highlighting worldwide trends and future research directions. A total of 95 peer-reviewed articles published between 2002–2019 were systematically analyzed. An exponential rise in research effort is demonstrated, with 80 % of the articles being published since 2015. The majority of these studies (62.1 %) focused on the neighborhood followed by the city scale (14.7 %). Min-max normalization (30.5 %), equal weighting (24.2 %), and linear aggregation (80.0 %) were the most common methods. With regard to the indicators used, a focus was given to socio-economic aspects (e.g. population density, illiteracy rate, gender), whilst components associated with the citizen's coping and adaptive capacity were slightly covered. Gaps in current research include a lack of sensitivity and uncertainty analyzes (present in only 9.5 % and 3.2 % of papers, respectively); inadequate or inexistent validation of the results (present in 13.7 % of the studies); lack of transparency regarding the rationale for weighting and indicator selection; and use of static approaches, disregarding temporal dynamics. We discuss the challenges associated with these findings for the assessment of flood vulnerability and provide a research agenda for attending to these gaps.

Herding denotes how individuals act together in a group without any centralized direction. Herding is widely studied as it drives asset prices away from the fundamental value and there are concerns it leads to volatility, destabilizes the market and increases the fragility of the financial market. In this paper, a concise review of the literature of herding is provided.  Various types of herding, its significance and occurrences along with the determinants are discussed. Various approaches used for measuring herding have been reviewed.  The relationship of herding along with other variables such as market conditions, volatility, and liquidity is reviewed and studied. For the purpose of drafting the review paper, 79 papers for over three decades have been consulted.  Further, future research directions are included for the benefit of the academicians, researchers and policymakers.
