Abstract
Purpose
The Denial of Service (DoS) attack is a category of intrusion that devours various services and resources of the organization by the dispersal of unusable traffic, so that reliable users are not capable of getting benefit from the services. In general, the DoS attackers preserve their independence by collaborating several victim machines and following authentic network traffic, which makes it more complex to detect the attack. Thus, these issues and demerits faced by existing DoS attack recognition schemes in cloud are specified as a major challenge to inventing a new attack recognition method.
Design/methodology/approach
This paper aims to detect DoS attack detection scheme, termed as sine cosine anti coronavirus optimization (SCACVO)-driven deep maxout network (DMN). The recorded log file is considered in this method for the attack detection process. Significant features are chosen based on Pearson correlation in the feature selection phase. The over sampling scheme is applied in the data augmentation phase, and then the attack detection is done using DMN. The DMN is trained by the SCACVO algorithm, which is formed by combining sine cosine optimization and anti-corona virus optimization techniques.
Findings
The SCACVO-based DMN offers maximum testing accuracy, true positive rate and true negative rate of 0.9412, 0.9541 and 0.9178, respectively.
Originality/value
The DoS attack detection using the proposed model is accurate and improves the effectiveness of the detection.

Abstract
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract
Our research aims to understand how coopetition can create barriers to tourism by focussing on the collective interests that seek to preserve the identity of a geographical indication (GI). We conducted a qualitative longitudinal study that analyses a Brazilian wine industry, specifically the Vale dos Vinhedos (a GI region in Southern Brazil), because it provides examples of leveraging coopetition to develop the area. The study was conducted over 10 years (2012–2022), collecting primary data from representatives of the Brazilian wine industry in 36 semi-structured interviews. Interviewees emphasised how the Vale dos Vinhedos vocation is founded on natural beauty and tranquillity, aiming to preserve aspects that value wine culture. The study found that wineries and formal institution agents established a coopetition strategy to stop uncontrolled expansion in real-estate development, blocking the entry of new ventures such as hotels and timeshares that could distort the region's character. Consequently, coopetition does not merely hinder the progression of tourism to real estate ventures; instead, it functions as an informal, and occasionally a formal, regulatory mechanism. While initially perceived as a drawback, upon examining the social, cultural, and economic advantages, this phenomenon emerges as a market control strategy that enhances the region.

Abstract
Rather than organize as traditional firms, many of today’s companies organize as platforms that sit at the nexus of multiple exchange and production relationships. This chapter considers a most basic question of organization in platform contexts: the choice of boundaries. Herein, I investigate how classical economic theories of firm boundaries apply to platform-based organization and empirically study how executives made boundary choices in response to changing market and technical challenges in the early mobile computing industry (the predecessor to today’s smartphones). Rather than a strict or unavoidable tradeoff between “openness-versus-control,” most successful platform owners chose their boundaries in a way to simultaneously open-up to outside developers while maintaining coordination across the entire system.

Abstract
Once in a while, you should take stock of your personal computing environment. What is on your system? How did it get there? What do you actually use? How did you arrive at your hardware configuration, and does it still meet your needs? You may find that you can free up some disk space in the process; at the very least, you'll understand your situation better. The author goes through this exercise both as an example of what it can show and because full disclosure is important for this series of articles. You need to know the background for the advice that appears here. The author discloses his current computing environments, how they got that way, and what that may mean. He also points out the real limits within which he operates as a PC commentator. When you go through the software on your system, you should check to see whether it represents ethical computing. The author offers a few notes on ethical issues related to software. The author also provides notes from PC literature for January‐June 1992.

Abstract
Purpose
Taking the subordinates’ perspective, this paper aims to explore the supervisor-subordinate relationships and how daily interactions, personal ties and connections with the supervisors contribute more significantly, positively or negatively, to the subordinates’ well-being.
Design/methodology/approach
This exploratory study is based on the thematic analysis of data collected from two rounds of in-depth semi-structured interviews with 21 participants in a Portuguese utility company.
Findings
The subordinates’ perceptions of the nature and quality of their relationships with supervisors were found to have considerable effects on well-being. Positive effects were identified when subordinates feel emotionally supported and believe that supervisors truly care about them and are genuinely willing to listen to their concerns, but the most significant effects on the subordinates’ well-being are produced when the perceived authenticity of the supervisor allows the relationship to evolve into a state of relational closeness, and the subordinates connect with the person-as-real, the human being behind the mask who is playing the supervisory role. These findings reflect features of the cultural setting where the study was conducted.
Originality/value
The study provides evidence to support the argument that a better understanding of supervisor-subordinate relationships and their effects on well-being requires an integrated approach that considers the valuable contributions of different literatures and theoretical frameworks and the multiple dimensions of that relationship, including personal and non-work dimensions. This approach is particularly relevant in cultural contexts where these dimensions might play a critical role in work relations.
Proposito
Tomando la perspectiva de los subordinados, el artículo explora las relaciones supervisor-subordinado y cómo las interacciones diarias, los vínculos personales y las conexiones con los supervisores contribuyen de manera más significativa, positiva o negativamente, al bienestar de los subordinados.
Metodología
Este estudio exploratorio se basa en el análisis temático de los datos recopilados en dos rondas de entrevistas semiestructuradas en profundidad con veintiún participantes en una empresa de servicios públicos portuguesa.
Resultados
Se encontró que las percepciones de los subordinados sobre la naturaleza y calidad de sus relaciones con los supervisores tienen efectos considerables en el bienestar. Se identificaron efectos positivos cuando los subordinados se sienten apoyados emocionalmente por los supervisores y creen que realmente se preocupan con elles y están genuinamente dispuestos a escuchar sus preocupaciones. Los efectos más significativos en el bienestar de los subordinados se producen cuando la autenticidad percibida de los supervisores permite que la relación evolucione hacia un estado de cercanía relacional, y los subordinados se conectan con la persona real, el ser humano detrás de la máscara, que es el supervisor.
Originalidad/valor
Este estudio proporciona evidencia que respalda la idea de que una mejor comprensión de las relaciones supervisor-subordinado y sus efectos en el bienestar requiere un enfoque integrado que tenga en cuenta las valiosas contribuciones de diferentes literaturas y marcos teóricos y las múltiples dimensiones de esa relación, incluidas las dimensiones personales y no laborales, para dar sentido a las relaciones supervisor-subordinado en contextos culturales donde podrían desempeñar un papel fundamental.
Objetivo
A partir da perspectiva dos subordinados, o artigo explora as relações supervisor-subordinado e como as interações diárias, os laços pessoais e as ligações com os supervisores contribuem de forma mais significativa, positiva ou negativamente, para o bem-estar dos subordinados.
Metodologia
Este estudo exploratório baseia-se na aplicação da análise temática aos dados recolhidos em duas rondas de entrevistas semiestruturadas e em profundidade a vinte e um participantes, em exercício de funções em empresa portuguesa de serviços públicos.
Resultados
Os dados recolhidos permitem concluir que as percepções dos subordinados sobre a natureza e a qualidade das suas relações com os supervisores têm efeitos consideráveis no bem-estar. Foram identificados efeitos positivos quando os subordinados sentem que os supervisores os apoiam emocionalmente e realmente se preocupam com os subordinados e estão genuinamente dispostos a ouvir as suas preocupações. Os efeitos mais significativos no bem-estar são obtidos quando dos subordinados percepcionam a autenticidade do supervisor, permitindo que o relacionamento evolua para um estado de proximidade relacional, e os subordinados se conectam com a pessoa real, o ser humano por detrás da máscara: o supervisor.
Originalidade/valor
O estudo fornece evidência que permite sustentar o argumento segundo o qual uma melhor compreensão das relações supervisor-subordinado e dos seus efeitos no bem-estar exige uma abordagem integrada que tenha em conta as contribuições valiosas de diferentes literaturas e quadros teóricos e as múltiplas dimensões da relação supervisor-subordinado, incluindo a dimensão pessoal e não profissional, particularmente relevantes em contextos culturais em que estas podem desempenhar um papel crítico.

Abstract
Purpose
Wireless multi-hop ad hoc networks are becoming very attractive and widely deployed in many kinds of communication and networking applications. However, distributed and collaborative routing in such networks makes them vulnerable to various security attacks. This paper aims to design and implement a new efficient intrusion detection and prevention framework, called EIDPF, a host-based framework suitable for mobile ad hoc network’s characteristics such as high node’s mobility, resource-constraints and rapid topology change. EIDPF aims to protect an AODV-based network against routing attacks that could target such network.
Design/methodology/approach
This detection and prevention framework is composed of three complementary modules: a specification-based intrusion detection system to detect attacks violating the protocol specification, a load balancer to prevent fast-forwarding attacks such as wormhole and rushing and adaptive response mechanism to isolate malicious node from the network.
Findings
A key advantage of the proposed framework is its capacity to efficiently avoid fast-forwarding attacks and its real-time detection of both known and unknown attacks violating specification. The simulation results show that EIDPF exhibits a high detection rate, low false positive rate and no extra communication overhead compared to other protection mechanisms.
Originality/value
It is a new intrusion detection and prevention framework to protect ad hoc network against routing attacks. A key strength of the proposed framework is its ability to guarantee a real-time detection of known and unknown attacks that violate the protocol specification, and avoiding wormhole and rushing attacks by providing a load balancing route discovery.

Abstract
This chapter presents a comparative study of the trends and patterns of communication and tourism research in Brazil and the United States over the last 20 years. Through a bibliometric analysis of the CAPES and EBSCO databases, the study identifies the main theoretical and methodological references, classifies the fundamental themes in the area, and describes the role of communication for tourism. The results indicate the predominance in North American scientific literature of research related to the image and the brand of the tourist destinations, as well as the measurement and the evaluation of the communicative strategies. On the other hand, Brazilian research presents a greater diversity of approaches: destination image studies, tourism consumption, tourist narrative analysis, identities, social networks, community-based tourism, sports, and ecological tourism, with an explicit recognition of the dangers of sexual objectification and dehumanization within tourism. The survey showed that the scientific community has a strong interest in this area, signaling a search for knowledge to deepen the conceptual understanding of the subject. Thus, this chapter provides insights regarding the opportunities and directions for the next decades of research in this field of study.
