PurposeSince recent research has found that offensively oriented players receive a salary premium, the current study recognizes this observed premium might exist because offense is worth more in terms of revenue generation. Given the popular sports saying, “Offense sells tickets, defense wins championships,” the authors quantify whether offense really does sell more “tickets” than defense in the NBA.Design/methodology/approachUsing NBA team revenue data as well as team offensive and defensive win shares, the authors estimate several econometric specifications to test if teams generate more revenue for offensive wins compared to defensive wins. The authors also employ a multi-year free agency study to identify if NBA players receive more compensation for offensive production than they do for defensive production.FindingsThe authors find no statistical difference in revenue generation from offense compared to defense. The authors confirm these findings both before and after revenue sharing. These results are also robust to alternative specifications. Therefore, the authors conclude that fans do not prefer offense to defense in terms of their spending. Contrary to previous research, the authors find no evidence of an offensive premium paid to NBA players.Originality/valueBased on their findings, offensively oriented players should not receive a salary premium. The clear implication for team decision makers is that offensive production should be compensated at a similar rate as defensive production. Since the authors do not find evidence of an offensive premium for offensive production, their research suggests a likely labor market equilibrium in the NBA for both profit-maximizing and win-maximizing teams.

“…This can be understood as the social support equivalent of proactive emotional work-played offensively. In game theory, an offensive strategy actively seeks to score a goal, while a defensive strategy seeks to avoid conceded goals(Gambarelli et al, 2019). Adapted to the scope of this research, the offensive strategy, as argued for above, is a policy directed practice that seeks to influence the context around practice.Based on the above discussion, I argue that jurisdiction, policy and social support are tightly connected, and there is room for an offensively played policy practice that may influence social workers' jurisdiction in the field of PVE and other developing areas of social work.…”

Managing the tension between trust and security: A qualitative study of Norwegian social workers’ experience with preventing radicalisation and violent extremism

In Norway, social workers play a formalised part in the national strategy to prevent radicalisation and violent extremism. This part is played out by engaging with other services and organisations, such as the schools, health services, police and the police security service (PST), in a multiagency cooperation. In addition, social workers engage directly with individuals who have been deemed at risk of further radicalisation and are tasked with providing prevention and follow-up services. Norwegian social workers’ experiences from the work to prevent radicalisation and violent extremism (PVE) have not yet been specifically explored. Thus, this study asks the following main research question: How do Norwegian social workers experience and reflect upon their engagement in preventive work against radicalization and violent extremism? To answer this, an explorative qualitative study was devised utilizing data from 17 in-depth interviews and two focus-group interviews, analysed through an eclectic theoretical framework to reveal new knowledge. Furthermore, the study seeks to contribute to a theoretical development of social work in a new knowledge and practice field, alongside police and PST. The study finds that Norwegian social workers performing PVE experience tension from conflict expectations. First, Norwegian social workers frame and approach the task of PVE as a social issue and lean on common social worker strategies, and trustbuilding, in particular. This is labelled internal expectations. Next, through cooperation with police and PST, they are expected to participate in a more ‘secretive’ practices, where sensitive information flows more smoothly, without clients’ necessarily being aware of this. Analysis of this cooperation indicates that several types of jurisdictional settlements between social workers and the police, and PST in particular, exits. Of these, subordination to PST raise the most apparent ethical dilemmas for social workers. This practice influence and expectations from policy documents are labelled as external expectations. The conflict occurring between these two expectations create tension in the form of emotional dissonance and person role/conflicts. To cope with these, social workers apply emotion management strategies (internal management) as well as social support from peers and support staff (external management). As an extension of social support, where social workers may become aware of how policy and other professional logics influence their practice field, this thesis suggests that social workers may communicate these challenges to managers and policymakers through an offensive policy directed practice. These findings contribute to the development of the role of the social worker itself, influenced by security logics and policy, and suggests how this can be dealt with through a clearer demarcation between what is and what is not included in the tasks and responsibilities of social workers in PVE.
