Abstract
Purpose
The purpose of the study is to examine the efficiency of linear, nonlinear and artificial neural networks (ANNs), in predicting property prices.
Design/methodology/approach
The present study uses a dataset of 1,468 real estate transactions from 2020 to 2022, obtained from the Department of Property Taxes of Republic of Kosovo. Beginning with a fundamental linear regression model, the study tackles the question of overlooked nonlinearity, employing a similar strategy like Peterson and Flanagan (2009) and McCluskey et al. (2012), whereby ANN's predictions are incorporated as an additional regressor within the ordinary least squares (OLS) model.
Findings
The research findings underscore the superior fit of semi-log and double-log models over the OLS model, while the ANN model shows moderate performance, contrary to the conventional conviction of ANN's superior predictive power. This is notably divergent from the prevailing belief about ANN's superior predictive power, shedding light on the potential overestimation of ANN's efficacy.
Practical implications
The study accentuates the importance of embracing diverse models in property price prediction, debunking the notion of the ubiquitous applicability of ANN models. The research outcomes carry substantial ramifications for both scholars and professionals engaged in property valuation.
Originality/value
Distinctively, this research pioneers the comparative analysis of diverse models, including ANN, in the setting of a developing country's capital, hence providing a fresh perspective to their effectiveness in property price prediction.

Abstract
The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).

Abstract
Purpose
This paper aims to explore perceptions and provides insights, from students who volunteer in policing whilst also studying the college of policing licenced professional policing degree (PPD) in Wales. It examines issues that act as enablers and blockers to volunteering in this public service, which also provides opportunities to develop their employability towards the careers to which they aspire. The paper provides insights from students and makes recommendations of interest to multiple stakeholders locally, regionally, nationally and internationally regarding attracting and recruiting volunteers.
Design/methodology/approach
Focus groups were conducted with students at three separate universities in the South and West of Wales. These undergraduate students were volunteers in different police forces and agreed to take part in connection with their experiences. The results were analysed using NVivo to establish commonalities.
Findings
The paper provides empirical insights concerning the issues surrounding the way those undergoing the process for recruitment as volunteers within policing are either hindered (blocked) or assisted (enabled). It identifies specific problematic areas as well as areas which have been of assistance. Policy makers, educators and recruiters should be aware of such blockers and enablers when considering adopting volunteering as an opportunity to enhance student employability. It also has resonance for other forms of volunteering in alternate public services.
Research limitations/implications
This research is limited to those volunteers who are undertaking the licenced PPD at three separate universities in Wales. Although the research adds to the broader evidence-base with regards to volunteering and its use to enhance employability.
Practical implications
The paper includes practical implications for multiple stakeholders including university programme educators, administrators and decision makers in policing with regards to volunteering, employability, programme structures and process management.
Originality/value
The research is based upon the experiences and perceptions of those individuals who are actually engaged in volunteering.

Abstract
Climate change is a global issue with far-reaching environmental, social and economic consequences. As more people become aware of these consequences, pressure is mounting on governments and businesses to implement ambitious and required climate mitigation and adaptation plans to reduce and finally stop making the climate crisis worse. One of these strategies is just transition, which is defined as the call for climate transformation that prioritises the social and environmental needs of workers and vulnerable groups, especially in the context of transitioning away from fossil fuels, while leaving no one behind. This chapter first provides an overview of just transition through a review of the literature and bibliometric analysis. Then, it discusses just transition in policymaking, comprising reactive, proactive and transformational just transition approaches. This is followed by a discussion on barriers to just transition. Finally, the chapter offers a practical example of transformational just transition approach by reporting some preliminary findings from a case study in the coal mining town of Collie on Wilman Boodja, Western Australia.

Abstract
Purpose
The authors review the small but growing literature linking cognitive biases to food safety problems and foodborne illness outbreaks.
Design/methodology/approach
The authors conducted a search of peer-reviewed articles utilizing empirical methods published since the year 2000 focusing on food safety or foodborne illnesses/outbreaks and cognitive biases.
Findings
The authors find that most research is conducted at the consumer side of the food system, with few studies examining the potential problems that can arise in the production and processing of food. The authors also observe that most research tends to focus on a few cognitive biases.
Originality/value
This is the most comprehensive study to date examining insights from the literature on cognitive biases and the related discipline of behavioral economics to the specific problem of foodborne illness outbreaks and food safety problems.

Abstract
Purpose
In 2016, the oversight body for policing in England and Wales reported a national shortage of 5,000 qualified detectives and other investigators. Commissioned by the National Police Chiefs Council, this research critically assessed initiatives taken by the Police Service of England and Wales since that time to remedy that shortfall. The purpose of this study is to answer the question, “To what extent can fast-track investigator recruitment and training schemes enhance the PSEW’s investigative capacity and capability?”
Design/methodology/approach
Between 2019 and 2020, the authors examined four cases in England and Wales. Three were novel fast-track programmes for new joiners. The fourth was an investigator resilience programme. This study was qualitative and interpretive in nature. The authors carried out systematic reviews of the literature on investigative policy and detective work. The authors reviewed internal evaluations completed by Forces A, B and C. The authors interviewed respondents (n = 82) and supplemented the interview data with survey data (n = 45; N = 127); the authors analysed the data thematically and reviewed the findings in the context of systems theory and social identity theory.
Findings
The major themes identified by the analysis presented in this study were marketing and recruitment, attrition and progression, acceptance of the trainees, training and trainees’ welfare and well-being. The programmes were not as successful as they might have been because of systems failures. Principally, ineffective coordination of the programmes with other elements of the forces on which their success also relied (such as training, human resources and detective, departments). A critical limiting factor was the lack of experienced, skilled detectives able to train, support and mentor the trainees.
Practical implications
This paper provides empirical evidence of the efficacy of a whole systems approach to organisational change. This study evidences the crisis in police investigative practice that limits the service that the police can provide to victims and communities and ultimately threatens police legitimacy. This study provides insights from police practitioners into detective work in the modern era and highlights areas where improvement is necessary. The research on which this study is based was commissioned by the National Police Chiefs Council. Thus, there is institutional buy in to its findings.
Originality/value
With its roots firmly in empiricism, this paper presents the first scholarly evaluation of the police's attempts to make up a massive shortfall in investigators. To the best of the authors’ knowledge, this paper presents the first attempt to explain the challenges the police faced in this context, thematically. This study’s focus on systems and on human behaviour is intended to inform a wide audience beyond British policing.

Abstract
Purpose
This study aims to identify the political alignment and political activity of the 11 Presidents of Britain’s most important scientific organisation, the Royal Society of London, in its early years 1662–1703, to determine whether or not the institution was politically aligned.
Design/methodology/approach
There is almost no information addressing the political alignment of the Royal Society or its Presidents available in the institution’s archives, or in the writings of historians specialising in its administration. Even reliable biographical sources, such as the Oxford Dictionary of National Biography provide very limited information. However, as 10 Presidents were elected Member of Parliament (MP), The History of Parliament: British Political, Social and Local History provides a wealth of accurate, in-depth data, revealing the alignment of both.
Findings
All Presidents held senior government offices, the first was a Royalist aristocrat; of the remaining 10, 8 were Royalist or Tory MPs, 2 of whom were falsely imprisoned by the House of Commons, 2 were Whig MPs, while 4 were elevated to the Lords. The institution was Royalist aligned 1662–1680, Tory aligned 1680–1695 and Whig aligned 1695–1703, which reflects changes in Parliament and State.
Originality/value
This study establishes that the early Royal Society was not an apolitical institution and that the political alignment of Presidents and institution continued in later eras. Furthermore, it demonstrates how the election or appointment of an organisation’s most senior officer can be used to signal its political alignment with government and other organisations to serve various ends.

Abstract
In 2020, Sports Illustrated proclaimed its “Sportsperson of the Year” as something dubbed “the activist athlete,” choosing five athletes – LeBron James, Breanna Stewart, Patrick Mahomes, Naomi Osaka, and Laurent Duvernay-Tardif – that represented the term. Like so many athletes who came before them, these athletes vividly demonstrate the potential of sport to shine a spotlight on critical issues in society, yet again solidifying how sport does not exist merely as some kind of escape, but is a major stakeholder in global campaigns for social justice.
This chapter historicizes the contemporary resurgence of athlete activism, largely connected to the reawakening of Black Lives Matters (BLM) in 2020, within what journalist Howard Bryant has called The Heritage, with athletes who acknowledge and accept the charge to use their spotlights for those who have none. From the turning point of the Mexico City Olympics in 1968, which saw collective movements of African-American athletes culminate in the powerful Black power protest by Tommie Smith and John Carlos, a protest that built upon the legacies of so many, to the ongoing debates that surround the International Olympic Committee's (IOC) Rule 50, athletes have long understood how sport serves not only as an integral part of society but also as an agent for change. Contemporary cries for athletes to “shut up and dribble” echo past claims that sport takes place on a level playing field that transcends politics. The history of sports demonstrates otherwise, as athletes embody every imaginable, intersectional, classification of political actor.

Abstract
I suggest that the search for Adam Smith’s theodicy is likely to be in vain. The paper begins with a brief history of approaches to evil, emphasizing the context in which they arose, and the questions authors were addressing. Approaches most relevant to Adam Smith include those of Augustine and Calvin, and the early modern theodicies of Leibniz, Samuel Clarke and William King, as well as the attacks on them by Bayle and Voltaire. Scottish Enlightenment writers were not terribly interested in theodicy, though Hutcheson and Kames did devote space to their versions of problems of evil. David Hume’s Dialogues on Natural Religion are often taken to be classic statement of the problem of theodicy and argument against religious belief, but his concern was to demolish rationalistic theodicies rather than religious belief or practice. The paper then turns to Smith’s writings, considering similarities and differences to these approaches to evil. Smith emphasizes the wisdom and beneficence of God, and that evils we observe are part of a larger providential plan. He makes no attempt to justify the God in the face of evil, and in this respect Smith shares more with Augustine and Calvin than he does with the early modern theodicists. Smith’s approach to evil is simple and ameliorative. Smith’s approach contrasts with early nineteenth century English political economists, from Malthus onwards, for whom theodicy was important. Whatever view we take of the theodicists project of justifying an all-powerful and good God in the face of evil may, we still struggle to make sense of economic suffering and evil.
