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.

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.
