Abstract
Purpose
Many universities implemented institutional social networking apps as an alternative to in-person social experiences during the COVID-19 pandemic. Therefore, this study aims to explore previously identified factors that influenced intentions to form collective actions, also known as we-intentions, on such social networking apps and their influence on student satisfaction with the app artifact.
Design/methodology/approach
Students from across a large university were invited to participate in a survey. Responses from 915 students who reported using the app were analyzed using a maximum likelihood covariance-based structural equation model. Analysis was conducted using the R programming language's psych, lavaan, and semTools packages.
Findings
The authors found that we-intentions are positively associated with recent app use and with student satisfaction with the app. Group norms were found to significantly influence the formation of we-intentions, while social identity is positively associated with both we-intentions and satisfaction.
Originality/value
The paper provides evidence that past research generalizes to the context of university mobile social networks and identifies a relationship between we-intentions and satisfaction in this context. It also provides practical insight into factors that influence we-intentions, and subsequently students' online education experience, in the context of a university's institutional mobile social network.

Abstract
Purpose
This paper aims to determine the conditions for the core of the Triple Helix game to exist. The Triple Helix of university-industry-government relationships is a three-person cooperative game with transferable utility. Then, the core, the Shapley value and the nucleolus were used as indicators of the synergy within an innovation system. Whereas the Shapley value and the nucleolus always exist, the core may not.
Design/methodology/approach
The core of a three-person cooperative game with transferable utility exists only if and only if the game is convex. The paper applies the convexity condition to the Triple Helix game.
Findings
The Triple Helix game is convex if and only if there is output within the system; it is strictly convex if and only if all the three bilateral and the trilateral relationships have an output.
Practical implications
Convex games are competitive situations in which there are strong incentives towards the formation of large coalitions; therefore, innovation actors must cooperate to maximise their interests. Furthermore, a Triple Helix game may be split into subgames for comprehensive analyses and several Triple Helix games may be combined for a global study.
Originality/value
This paper extends the meaning of the Shapley value and the nucleolus for Triple Helix innovation actors: the Shapley value indicates the quantity a player wins because of the coalitions he involves in and the nucleolus the return for solidarity of an innovation actor.

A cross-domain intelligent software-defined network (SDN) routing method based on a proposed multiagent deep reinforcement learning (MDRL) method is developed.
Abstract
Purpose
A cross-domain intelligent software-defined network (SDN) routing method based on a proposed multiagent deep reinforcement learning (MDRL) method is developed.
Design/methodology/approach
First, the network is divided into multiple subdomains managed by multiple local controllers, and the state information of each subdomain is flexibly obtained by the designed SDN multithreaded network measurement mechanism. Then, a cooperative communication module is designed to realize message transmission and message synchronization between the root and local controllers, and socket technology is used to ensure the reliability and stability of message transmission between multiple controllers to acquire global network state information in real time. Finally, after the optimal intradomain and interdomain routing paths are adaptively generated by the agents in the root and local controllers, a network traffic state prediction mechanism is designed to improve awareness of the cross-domain intelligent routing method and enable the generation of the optimal routing paths in the global network in real time.
Findings
Experimental results show that the proposed cross-domain intelligent routing method can significantly improve the network throughput and reduce the network delay and packet loss rate compared to those of the Dijkstra and open shortest path first (OSPF) routing methods.
Originality/value
Message transmission and message synchronization for multicontroller interdomain routing in SDN have long adaptation times and slow convergence speeds, coupled with the shortcomings of traditional interdomain routing methods, such as cumbersome configuration and inflexible acquisition of network state information. These drawbacks make it difficult to obtain global state information about the network, and the optimal routing decision cannot be made in real time, affecting network performance. This paper proposes a cross-domain intelligent SDN routing method based on a proposed MDRL method. First, the network is divided into multiple subdomains managed by multiple local controllers, and the state information of each subdomain is flexibly obtained by the designed SDN multithreaded network measurement mechanism. Then, a cooperative communication module is designed to realize message transmission and message synchronization between root and local controllers, and socket technology is used to ensure the reliability and stability of message transmission between multiple controllers to realize the real-time acquisition of global network state information. Finally, after the optimal intradomain and interdomain routing paths are adaptively generated by the agents in the root and local controllers, a prediction mechanism for the network traffic state is designed to improve awareness of the cross-domain intelligent routing method and enable the generation of the optimal routing paths in the global network in real time. Experimental results show that the proposed cross-domain intelligent routing method can significantly improve the network throughput and reduce the network delay and packet loss rate compared to those of the Dijkstra and OSPF routing methods.

Abstract
Purpose
Researchers, academicians and practitioners are trying to make employees more mindful, as mindfulness brings a lot of excellence to work. This study aims to unwrap and decode the mindfulness procedure by identifying the crucial steps to ease the process for employees and organisations.
Design/methodology/approach
The qualitative research method assessed 20 semi-structured interviews with mindfulness experts in India and abroad. Interpretive phenomenological analysis was used to analyse the content generated by the data collection.
Findings
Though the understanding of mindfulness is univocal and standard, this investigation fills the gap of initial groundwork concerning thoughtlessness, as it remains a less observed area in earlier research in mindfulness. This research study also found organisational ways to enhance mindfulness in the system, such as ostentatious listening, detail orientation, deep discussions, one task at a time, etc.
Originality/value
The study is unique in that it explores the perceptions and views of mindfulness coaches and masters and tries to demystify the procedure of being mindful in organisations.

Abstract
Uncontrollable movement of people across international borders is one of most pressing contemporary challenge encountered by nation-states. Their response to this challenge is often rooted on a reconceptualisation of (in)security from a state-centric to a non-state-centric one. This has been the case with Australia where insecurity from asylum seekers, or what is referred to as the ‘boat people’, dominating the country's discourse on protecting its borders. Such conceptions are rooted on historical anxieties from ‘foreigners’, resulting in exclusionary policies of ‘White Australia’ to recent assertions of exclusive sovereignty over the refugee intake. In this context, while reviewing government documents, reports and other secondary sources, the chapter examines Australia's policy towards asylum seekers domestically as well as at the regional level, while placing them within the broader debate between deterrence and human rights. The chapter is significant as it provides an important case study of the inherent contradictions that come into light in a nation-state's response towards refugees on the one hand and undocumented arrivals, in this case, the ‘boat people’ on the other. This chapter provides analytical support to the primary assertion that while Australia has been an active international player regarding refugee issues, there is bipartisan exclusivity and hard-handedness towards asylum seekers.

Abstract
This chapter provides an introduction to the world of family companies and family constitutions from a legal perspective. It first studies the legal types of business organizations that family firms have chosen across time and jurisdictions. It then illustrates how early predecessors of family constitutions evolved in the late Middle Ages and what modern family constitutions look like in different countries today. Further considerations are devoted to the governance framework of family firms. The chapter concludes by exploring the potential legal effects of family constitutions under German company and contract law.

Abstract
Purpose
Scams are indeed malicious attempts to influence people and can take many forms, including online scams. With the increasing availability of technology, scammers have more tools at their disposal to create convincing and sophisticated communications that appear to come from legitimate sources, such as emails, text messages or social media posts. These scams can be designed to trick individuals into clicking on malicious links, downloading malware or ransomware or providing sensitive information such as login information, financial information or personal details. Scammers often use social engineering techniques to persuade their targets to take specific actions, such as creating a sense of urgency, offering a reward or prize or posing as a trusted authority. These tactics can be highly effective, particularly if the target is unaware of the warning signs of a scam or is unfamiliar with how to protect themselves from online fraud. This paper aims to explore the extent and nature of this problem and evokes the concern that the general public is vulnerable and susceptible to scams if they are not resilient and aware. This paper also explores why victims fall for online scams and uncovers preventive measures to enable a direction in tacitly strategizing ways to create more impactful and effective awareness campaigns.
Design/methodology/approach
This study explores these aspects through a holistic qualitative approach. Using in-depth interview techniques with six victims, six non-victims, four law enforcement officers, four scammers and seven stakeholders from various agencies such as banks, telecommunication agencies and the Malaysian Communications and Multimedia Commission involved in combating the issue of scams.
Findings
The findings generally revealed that participants who were victims of scams felt Malaysians were susceptible to scams, easily fooled and had a nonchalant attitude. Most participants also highlighted that public safety is important for ensuring a high quality of life for citizens that should work closely between the government and non-government agencies, including effective law enforcement and crime prevention strategies.
Originality/value
The uniqueness of this study is the feedback from scammers themselves and their input towards authority and victims. Overall, the respondents provide their views drawing strength from the ever-changing technological background as well as the susceptibility of security features and vulnerability of human engagement.

Abstract
Purpose
The leaves of the Erythroxylum “coca” plant are a well-known food, beverage, and nutraceutical in their native Andean region. A decade ago, the European non-profit “Amigos de la Hoja de Coca” (Friends of the Coca Leaf) operated a short-lived fair-trade in raw coca leaves between Bolivia and the European Union. The chronicles of this initiative can be insightful, as interest in natural, wellness, and self-care products continues rising in Europe.
Design/methodology/approach
Historical review of the inception, and documentation of the organisation of the scheme and its outcome, via all primary sources available.
Findings
From the 1990s to the early 2010s, civil society groups organised several campaigns to normalise coca leaf in Europe, finding echo at the European Parliament, culminating in 2012-2013 when a periodical distribution system was set-up: growers in Bolivia shipped 150 g. coca leaf packets directly to Friends of the Coca Leaf members in Europe. Initially, most parcels reached their recipients without issue but after technical hurdles and reduced political support, the scheme was eventually discontinued.
Originality/value
European civil society campaigns surrounding coca have been poorly documented. Historically, Friends of the Coca Leaf emerged alongside Cannabis social clubs, but only the latter has prospered. While Friends of Coca Leaf was short-lived, its political outcomes (both at the institutional level and via a fair and do-it-yourself trade initiative) may prove inspirational to current drug policy reform discussions.
