Historical Constitution of Public Radio Stations in Brazil

Educational, state, cultural, and university radio stations have already developed over more than 70 years of history in Brazilian radio broadcasting. Currently, there are hundreds of stations transmitting across the country, from the North to the South. Some of them—that in the 1990s included 100 broadcasting stations and among these, the oldest and nationally referenced—up to this decade operated and were referenced as a component of the educational radio system. Mainly from this period on, most of these stations began to call themselves public. And, especially due to their programming, they have been attempting to define themselves within the profile of public radio stations. The purpose of this article is to uncover the historical construction of this group of radio broadcasting stations, by means of a timeframe, from the advent of the non-commercial segment in the 1930s until today. It reconstructs referential models and presents main threads and features of the programming of these stations throughout these seven decades. In this way, it will also evince how Brazil is constructing its model of public radio.     

A Critical Co-Constructed Autoethnography of a Gendered Cross-Cultural Mentoring Between Two Early Career Latin@ Scholars Working in the Deep South

Multicultural mentoring has been suggested to support Latin@ faculty success in their careers, yet current literature on effective mentorships of Latin@ faculty is limited. This critical co-constructed autoethnography draws on critical race theory (CRT) and latin@ critical race theory (LatCrit) frameworks to highlight the lived experiences and key elements of an effective gendered cross-cultural mentoring relationship in a Latin@ pretenure faculty dyad working in a predominantly White institution of higher education located in the Deep South of the United States. Drawing upon a methodological rhythm of sorts, a Black scholar acts as a muse providing testimonios and interpretations of a relationship existing among Latin@ scholars in predominantly White intellectual spaces. Findings from this critical co-constructed autoethnography note that a safe colored space supports effective mentoring, familismo, personalismo, enabling effective cross-cultural mentorship.     

Digital signatures and electronic records

This paper gives an overview of the archival issues that relate to digitally signed documents. First, by way of introduction, the advanced digital signature is presented briefly. In the second part, a number of problems are discussed that present themselves when a digital signature is used as a proof of authenticity and integrity for digital documents in general. In particular, it is also being investigated whether it makes any sense for the archivist to digitally sign all electronic records under his or her management. Problems relating to the (medium) long-term archiving of digitally signed documents are dealt with in the third part. After an overview of the sticking points for long-term validation (“Archival issues”) a number of possible solutions are discussed (“Solutions for long-term archiving”).

Does inside passing contribute to the high incidence of groin injuries in soccer? A biomechanical analysis

Groin injuries are common in soccer and often cause time-loss from training. While groin injuries have been linked to full effort kicking, the role of inside passing is unclear. Therefore, the purpose of this study was to investigate hip joint kinematics and muscle force, stress and contraction velocity for adductor longus and gracilis during inside passing. 3D kinematics of ten soccer players (23.4 yrs; 77.5 kg; 1.81 m) were captured with a motion capture system inside a Footbonaut. Muscle force and contraction velocity were determined with AnyBody Modelling System. Gracilis muscle forces were 9% lower compared to adductor longus (p = 0.005), but muscle stress was 183% higher in gracilis (p = 0.005). Contraction velocity reveals eccentric contraction of gracilis in the last quarter of the swing phase. Considering the combination of eccentric contraction, high muscle stress and the repetitive nature of inside passing, gracilis accumulates high loads in matches and training. These results indicate that the high incidence of groin injuries in soccer could be linked to isolated pass training. Practitioners need to be aware of the risk and refrain from sudden increases in the amount of pass training. This gives the musculoskeletal system time to adapt and might avoid career threatening injuries.     

ICT,public values and transformative government: A framework and programme for research

Many adjectives are used in the context of transforming government including making it more open, transparent, participative, agile, responsive and so forth. Most, if not all, of these adjectives are either in themselves public values or reflect one or more underlying public values. This paper examines the relationship between information and communications technology (ICT), transformative government and such public values and proposes a framework for further research. A study of the literature on public values is used to develop a typology of public sector values likely to be affected by ICT. This impact is examined for a number of these values. For others hypotheses about the impact of ICT on other values are then posited. It is argued that ICTs can and do have transformational impacts on public values, though not always for the better, concludes that values are a potential powerful lens for considering such impacts and sets out a programme of research into these relationships.     

Does war contribute to family violence against children? Findings from a two-generational multi-informant study in Northern Uganda

After 20 years of civil war in Northern Uganda, the continuity of violence within the family constitutes a major challenge to children's healthy development in the post-conflict era. Previous exposure to trauma and ongoing psychopathology in guardians potentially contribute to parental perpetration against children and dysfunctional interactions in the child's family ecology that increase children's risk of maltreatment. In order to investigate distal and proximal risk factors of child victimization, we first aimed to identify factors leading to more self-reported perpetration in guardians. Second, we examined factors in the child's family environment that promote child-reported experiences of maltreatment. Using a two-generational design we interviewed 368 children, 365 female guardians, and 304 male guardians from seven war-affected rural communities in Northern Uganda on the basis of standardized questionnaires. We found that the strongest predictors of self-reported aggressive parenting behaviors toward the child were guardians’ own experiences of childhood maltreatment, followed by female guardians’ victimization experiences in their intimate relationship and male guardians’ posttrautmatic stress disorder (PTSD) symptoms and alcohol-related problems. Regarding children's self-report of victimization in the family, proximal factors including violence between adults in the household and male guardians’ PTSD symptom severity level predicted higher levels of maltreatment. Distal variables such as female guardians’ history of childhood victimization and female guardians’ exposure to traumatic war events also increased children's report of maltreatment. The current findings suggest that in the context of organized violence, an intergenerational cycle of violence persists that is exacerbated by female guardians’ re-victimization experiences and male guardians’ psychopathological symptoms.
