The purpose of the article is to explore the perceptions of Brazilian game developers about the power relations between them and the sponsors of digital game platforms. It also aims to identify forms of collective action that developers can use to counteract the asymmetry of power.

The research employed an abductive approach, seeking empirical evidence that would challenge consolidated theory. To achieve this, semi-structured interviews were conducted with 25 Brazilian developers. The data were analyzed qualitatively using NVivo software. The aim was to resolve theoretical ambiguities identified in the literature review and to explore unexpected findings.

The study explores Brazilian game developers' perceptions through interviews, revealing their experiences within the industry’s concentrated structure and their use of collective action to navigate power dynamics.

The study's focus on Brazil limits the generalizability of its findings to the broader game development industry.

The study suggests Brazilian game devs can leverage collective action to counteract power imbalance with platforms, collaborate through events and projects and facilitate internationalization of their games.

The study suggests collective action could empower developers to challenge platform dominance and foster a stronger community among Brazilian game developers.

The article’s value lies in examining Brazilian devs' experiences within their specific industry context and highlighting collective action as a potential strategy for developers.

Network analysis is a well consolidated research area in several disciplines. Within management and organizational studies, network scholars consolidated a set of research practices that allowed ease of data collection, high inter case comparability, establishment of nomological laws and commitment to social capital motivation. This paper aims to elicit the criticism it has received and highlight the unsettled lacunae.

This paper sheds light on Network Analysis’s breakthroughs, while showing how its scholars innovated by responding to critics, and identifying outstanding debates.

The paper identifies and discusses three streams of criticism that are still outstanding: the role of human agency, the meaning of social ties and the treatment of temporality.

This paper brings to fore current debates within the Network Analysis community, highlighting areas where future studies might contribute.

Recent research has shed light on career trajectories outside enclosed organizations and linked individual careers to career fields. This article seeks to explore how individuals' trajectories are affected by structural changes in career fields.

By exploring several jazz musicians' biographies, a typical trajectory is built. In contrast with this typical trajectory, alternative successful trajectories are investigated.

The typical trajectory entails a successful introduction of a musician into a field, followed by increasing recognition among peers at jam sessions, stream of engagements and among critics. Consecration of one's public persona occurs in tandem with the institutionalization of one's personal style. These higher levels of “symbolic capital” grant continuous streams of engagements, which in turn are translated into higher levels of economic capital. As a musician achieves a dominant position in a field, inertial forces typecast him, impeding innovation, which leaves room for upcoming younger artists. This model is contrasted with deviant careers that proved to be successful due to structural changes in the field. As the legitimacy sources were no longer tightly coupled, musicians were able to undertake choices not prescribed by successful predecessors. The way individuals behave when facing field uncertainty reveals the enduring values underlying the employment and conversion of resources.

This research is based on qualitative research on jazz musicians' bios. Future research might further explore interpretative schemata applied by musicians facing career choices.

Practitioners might find controversial and conflictive sources of legitimacy opportunities for taking up alternative career paths. Conversely, structural changes might help analysts to assess endurable patterns of individual strategic choices.

The logics of jazz musicians' trajectories are assumed to be analogous to other industry careers. This analogy adds value to the study of careers in two ways: first, it contributes to understanding career patterns outside formal organizations; and second, it permits a multi‐level analysis, where both individual trajectories and the field dynamics are interwoven.

As stated in the United Nations Global Assessment Report 2022 Concept Note, decision-makers everywhere need data and statistics that are accurate, timely, sufficiently disaggregated, relevant, accessible and easy to use. The purpose of this paper is to demonstrate scalable and replicable methods to advance and integrate the use of earth observation (EO), specifically ongoing efforts within the Group on Earth Observations (GEO) Work Programme and the Committee on Earth Observation Satellites (CEOS) Work Plan, to support risk-informed decision-making, based on documented national and subnational needs and requirements.

Promotion of open data sharing and geospatial technology solutions at national and subnational scales encourages the accelerated implementation of successful EO applications. These solutions may also be linked to specific Sendai Framework for Disaster Risk Reduction (DRR) 2015–2030 Global Targets that provide trusted answers to risk-oriented decision frameworks, as well as critical synergies between the Sendai Framework and the 2030 Agenda for Sustainable Development. This paper provides examples of these efforts in the form of platforms and knowledge hubs that leverage latest developments in analysis ready data and support evidence-based DRR measures.

The climate crisis is forcing countries to face unprecedented frequency and severity of disasters. At the same time, there are growing demands to respond to policy at the national and international level. EOs offer insights and intelligence for evidence-based policy development and decision-making to support key aspects of the Sendai Framework. The GEO DRR Working Group and CEOS Working Group Disasters are ideally placed to help national government agencies, particularly national Sendai focal points to learn more about EOs and understand their role in supporting DRR.

The unique perspective of EOs provide unrealized value to decision-makers addressing DRR. This paper highlights tangible methods and practices that leverage free and open source EO insights that can benefit all DRR practitioners.

State and national initiatives place an increased emphasis on both students’ exposure to diverse texts and teachers’ integration of English/language arts and history/social studies. The intent is for students to critically examine diverse accounts and perspectives of the same historical event or era. Critical examination can be accomplished through teachers’ purposeful juxtaposition of age-appropriate, engaging trade books and relevant informational texts, such as primary source materials. To guide interested elementary and middle level teachers, researchers can evaluate trade books for historical representation and suggest divergent or competing narratives that compel students to scrutinize diverse perspectives. Researchers can locate germane primary sources and modify them in ways that maintain their historicity. As students read, they scrutinize, contextualize, and corroborate sources, which enables them to actively construct historical understandings. We examined children’s literature centered on child labor. We juxtaposed trade books targeting elementary students with those intended for middle level students. While our findings revealed various forms of historical misrepresentation, child labor trade books appear far more historically representative than those centered on slavery.

Emotions are complex concepts involving multiple systems within the body and mind. How, when and for what purpose emotions are expressed is based on context and relationships. In this chapter I take a relational view of emotion and emotion regulation as applied in classroom settings. I first discuss the concepts of emotion and emotion regulation before exploring the physical, social and psychological processes involved in both producing and regulating emotions. Although teachers use, respond to and regulate emotions as part of their everyday work, I suggest that teachers are underprepared for the extent of the emotion work they encounter, or the cost it may have on their emotional reserves. The requirements to successfully navigate emotions in today's educational environment are underappreciated. Only when we acknowledge the relational and cognitive tasks required of teachers under the demand of multiple relationships and the constraints of the responsibilities placed upon them can we fully appreciate the magnitude of the endeavour.

The purpose of the present study is to examine associations between post‐traumatic stress disorder (PTSD) symptoms and salivary cortisol parameters.

PTSD symptoms and cortisol responses were measured in a random sample of 100 police officers. The impact of event scale (IES) categorized into subclinical, mild, moderate and severe levels was employed to measure PTSD symptoms. Cortisol was analyzed from saliva samples over a period of three days and included an awakening response, high protein lunch challenge, whole day (diurnal), and a dexamethasone suppression test (DST).

Officers in moderate and severe PTSD symptom categories had higher mean awakening cortisol values. A significant sample‐time by PTSD interaction (p=0.008) was found for awakening cortisol responses. Officers in the severe PTSD symptom category showed a blunted response to the cortisol protein meal challenge compared to those in lower PTSD categories. Diurnal cortisol levels suggested an increasing trend across subclinical to severe PTSD categories respectively (p=0.15 test for trend). DST ratios were lower in moderate and severe PTSD symptom categories (6.86 and 8.03 respectively) than in the subclinical and mild categories (9.32 and 10.43 respectively).

The sample was not representative of all police in the USA. These results suggest that associations between psychological trauma symptoms and dysregulation of cortisol patterns may exist and could possibly affect future health outcomes in police officers.

Exposure to trauma and disaster events emphasizes the need to further investigate the health impact of PTSD on police personnel as well as other first responder groups.

This article will not only be of interest to those in the police service but to the general public. The present study may serve to provide a guide for larger police population investigations on PTSD and physiological impact.
