From the buying club’s perspective, the transfer of a player can be interpreted as an investment from which the club expects uncertain future benefits. This paper aims to develop a decision-oriented approach for the valuation of football players that could theoretically help clubs determine the subjective value of investing in a player to assess its potential economic advantage.

We build on a semi-investment-theoretical risk-value model and elaborate an approach that can be applied in imperfect markets under uncertainty. Furthermore, we illustrate the valuation process with a numerical example based on fictitious data. Due to this explicitly intended decision support, our approach differs fundamentally from a large part of the literature, which is empirically based and attempts to explain observable figures through various influencing factors.

We propose a semi-investment-theoretical valuation approach that is based on a two-step model, namely, a first valuation at the club level and a final calculation to determine the decision value for an individual player. In contrast to the previous literature, we do not rely on an econometric framework that attempts to explain observable past variables but rather present a general, forward-looking decision model that can support managers in their investment decisions.

This approach is the first to show managers how to make an economically rational investment decision by determining the maximum payable price. Nevertheless, there is no normative requirement for the decision-maker. The club will obviously have to supplement the calculus with nonfinancial objectives. Overall, our paper can constitute a first step toward decision-oriented player valuation and for theoretical comparison with practical investment decisions in football clubs, which obviously take into account other specific sports team decisions.

This systematic review (SR) aims to evaluate and summarize the effectiveness of using eye movement desensitization and reprocessing (EMDR) intervention among individuals diagnosed with post-traumatic stress disorder (PTSD), as well as to highlight the standardized EMDR-based interventional protocol.

This SR is guided according to preferred reporting items for SRs and meta-analyses standards. Several online databases were used in searching for eligible studies in peer-reviewed journals relevant to the study keywords. The included studies were SRs and clinical trials that used EMDR interventions among patients experiencing PTSD symptoms, older than 18 years and were published in English language from 2015 to 2022. Three researchers independently contributed to study selections, data extraction and study evaluations from different aspects, including quality assessment, risk of bias and study synthesis.

A total of eight published studies met the inclusion criteria and were included in this SR; four articles were randomized controlled trials and four were SR and meta-analysis studies. In all included studies, the EMDR was used as a primary psychotherapy intervention for PTSD symptoms. The results of this extensive and comprehensive review showed that EMDR is an effective psychotherapeutic intervention to reduce and control the severity of symptoms among individuals with PTSD.

It is important to acknowledge several limitations inherent in this study. First and foremost, it is noteworthy to mention that only studies conducted in the English language were included in this review, potentially restricting the overall scope and diversity of the findings. Furthermore, the number of studies incorporated into this review was limited, which may have implications for the comprehensiveness and generalizability of the results. Finally, it is worth noting that certain studies within this review had a relatively small sample size, which could potentially limit the statistical power and precision of the conclusions drawn.

This paper, a review of the literature, gives an overview of EMDR effectiveness, provides baseline information and plays a significant role in decreasing the gap in Jordanian literature regarding using EMDR as the strongest evident psychotherapy approach for PTSD treatment to help psychiatrists, psychologists and psychiatric nurses in the health-care sectors to design comprehensive strategies to enhance and improve the quality of health care and patients’ status.

EMDR intervention offers significant alternative treatment opportunities for individuals suffering from PTSD, depression and anxiety. The implementation of EMDR for depression, anxiety and PTSD improves patient outcomes as compared to standard therapeutic modalities in PTSD.

This SR gives an overview and explains strong supportive evidence for the effectiveness of EMDR interventions among individuals with PTSD. Therefore, EMDR therapy could be assumed as one standard treatment option for PTSD, aiming at reducing treatment duration and cost of treatment and restoring the mental well-being and functionality of those suffering from PTSD.

Over the past years, non-fungible tokens (NFTs) have sparked growing interest in the sport industry. NFTs are unique digital assets verified using blockchain technology. Each NFT has a distinct identifier that sets it apart from other tokens, documenting its uniqueness and ownership. NFTs promise innovative growth opportunities by generating revenue via novel products such as digital collectibles which can be owned and traded on dedicated platforms. Despite this promising outlook, it currently seems unclear how sports NFTs should be designed and which features they should offer to align with consumer values, effectively meet their needs and ultimately drive Purchase Intention. This study will therefore attempt to answer the following research question: Which consumer values and consumer needs have a positive impact on PI of sports NFTs? Based on the results, the study seeks to offer advice on concrete characteristics sports NFTs should possess in order to foster mainstream adoption.

To address the current gap in the literature and provide an answer to the research question, this paper uses structural equation modelling exploring the impact of consumer values and consumer needs or wants on purchase intention regarding sports NFTs.

The results of this study indicate that social needs or wants (SNW) have the strongest impact on purchase intention, as well as on experiential and functional needs or wants. NFTs should therefore possess characteristics that foster community, interaction and connection with other team or athlete supporters while enhancing the overall consumer experience. Incorporating these elements into future NFTs can help sports organizations tap into the social SNW of consumers by providing opportunities for connection, interaction and collective experiences within supporter communities.

Due to the low response rate of Baby Boomers, the results of the study cannot be applied to this cohort. Additional research, potentially using physical in-stadium surveys and targeted specifically at the BB cohort may shed light on their particular values, needs or wants and impact on sports NFT purchase intention. Moreover, Generation Z respondents may statistically be underrepresented in the sample due to the fact that only respondents aged 18 and older were included in the study. Hence, the part of Generation Z, which was born after March 2006 and had not yet come of age at the time of this research, was explicitly excluded from the survey. Results should be applied carefully to the population of sports team or athlete supporters due to the method of data collection which was based on convenience sampling and may therefore not be representative. Since the survey was exclusively administered online, people with no Internet access are not represented in this research.

Sports organizations and marketers can leverage the strong impact of SNW identified in this study to position their NFT portfolio accordingly. Using athletes themselves or other influencers as product ambassadors may trigger purchase intention of consumers. Additionally, it is crucial that socializing agents, such as family, friends, colleagues and other team supporters with a strong influence on consumers own or promote NFTs. Marketers can support this adoption process by encouraging testimonials, reviews and user-generated content that showcase how NFTs have positively impacted others. Reaching a critical mass of adoption among supporters as a first step will ultimately impact consumers’ desire to satisfy ENW and FNW as well. Consumers may then recognize the benefits of using NFTs to enhance their overall consumer experience and to make their lives easier, for instance by using NFTs as season tickets or to collect loyalty points they can redeem later.

This study is the first attempt to determine the relationship between consumer values, consumers’ needs or wants and their impact on purchase intention regarding sports NFTs.

Recent scholarship calls for identifying conditions in which procedurally just treatment translate to increased police legitimacy. The present study draws on community justice and vitality and procedural justice literature to examine whether adolescent and young adults’ perceptions of legitimate work and school opportunities in their neighborhoods moderate the effects of fair treatment by police on perceptions of police legitimacy.

Longitudinal data from a justice-involved youth sample and a series of generalized linear mixed models are used to test the study’s hypotheses. We model “persons as contexts” and separate within-person and between-person effects.

Main effects models indicate that procedural justice and neighborhood opportunities both have significant within-individual, between-individual and person-contextual effects on police legitimacy. Results from interaction models indicate strong support for a person-contextual interaction effect. Net of covariates, higher average perceptions of procedurally just treatment leads to greater average police legitimacy, but this effect erodes when individuals perceive weak educational and occupational opportunities in their neighborhoods over time.

Efforts to maximize police legitimacy may be enhanced through greater investment in community opportunity structures. This study highlights the need for public officials and police to support the educational and occupational vitality of communities as a key strategy to promote police legitimacy and optimize core aspects of the procedural justice model.

This paper presents the most up-to-date comprehensive meta-analysis of the effectiveness of interventions to enhance psychological capital (PsyCap). It also reports the first meta-analytic examination of longer-term effects (beyond the immediate post-intervention period).

This meta-analysis followed PRISMA 2020 guidelines and utilised the methodologies of Hunter and Schmidt (2004) and Borenstein et al. (2009). The search period was from 2006 until February 2023. A total of 40 studies (N = 4,207) were included in the meta-analyses. The analyses were performed using the Comprehensive Meta-Analysis (CMA) Version 4 software programme.

The results indicate that the impacts of interventions on PsyCap and each of its component resources are greater than those reported in a previous meta-analysis (Lupșa et al., 2020), with the strongest impacts on hope and optimism. Interventions had sustained positive effects on PsyCap, hope, resilience and optimism, but not efficacy, and the frequency of intervention sessions influenced the effectiveness of interventions on hope, efficacy and optimism. Interestingly, specific PsyCap-focussed interventions did not have the greatest impact on PsyCap or its component resources.

This study contributes to emerging research on wellbeing-oriented HRM and provides valuable insights into more effective design and implementation of interventions to enhance PsyCap and its component resources. These interventions are a promising form of investment in employees which may bring mutual gains for individuals and organisations. The present findings extend those of previous studies and specifically respond to the call for further research on the persistence of PsyCap intervention effects.
