Modeling the Effect of Screening and Treatment on the Transmission of Tuberculosis Infections

Tuberculosis (TB) is a chronic airborne disease caused mainly by Mycobacterium tuberculosis and has caused many deaths globally and Tanzania in particular due to failure or delayed intervention. In this paper, a deterministic mathematical model for transmission dynamics of TB with vaccination and screening the population for the purpose of identifying those for immediate treatment is formulated. The effective reproduction number is computed in order to measure the relative impact for individual or combined intervention for effective disease control. Numerical simulations of the basic reproduction number shows that, the combination of vaccination, screening and treatment is the most effective intervention for minimizing the transmission of TB in a population. Key words: Tuberculosis, Modeling, Screening, Treatment

Security, Local Community, and the Democratic Political Culture in Africa

In this study, the idea of the local African community as a social structure ensuring the security of its members is presented. An understanding of the concept of security is first briefly discussed, followed by the meaning of the concept of the local African community. The chapter also makes an a priori distinction between what one can call “moderate” and “radical” types of communal life and two case studies exemplifying them are presented. The chapter aims to analyze the trade off, in terms of provision of security, including economic security, by local communities, for the shaping of a democratic political culture in Sub-Saharan Africa. Most importantly, however, this chapter also highlights the rationality that underpins the seemingly low-quality democratic political activities of members of local African communities

Adolescents at risk of self-harm in Ghana: a qualitative interview study exploring the views and experiences of key adult informants

Background In Ghana, rates of self-harm in young people are as high as they are in high income countries. Self-reported interpersonal, familial and societal stressors form the most important background, and self-harm is seen by young people as a way of responding to that stress. In the present study, we obtained the views of key adult informants about self-harm among adolescents in Ghana – what they thought as possible reasons for self-harm in young people and what actions might be needed at an individual or population level to respond to the problem. Methods We interviewed face-to-face 11 adults, using a semi-structured interview guide. We used an experiential thematic analysis technique to analyse the transcribed interviews. Results The analysis identified five themes: “underestimating the prevalence of self-harm in adolescents”, “life on the streets makes self-harm less likely”, “self-harm in adolescents is socially and psychologically understandable”, “ambivalence about responding to adolescent self-harm”, and “few immediate opportunities for self-harm prevention in Ghana”. Adolescent self-harm was acknowledged but its scale was underestimated. The participants offered explanations for adolescent self-harm in social and psychological terms that are recognisable from accounts in high income countries. Low rates among street-connected young people were explained by their overarching orientation for survival. Participants agreed that identification was important, but they expressed a sense of inadequacy in identifying and supporting adolescents at risk of self-harm. Again, the participants agreed that self-harm in adolescents should be prevented, but they recognised that relevant policies were not in place or if there were policies they were not implemented – mental health and self-harm were not high on public or political priorities. Conclusions The adults we interviewed about young people who self-harm see themselves as having a role in identifying adolescents at risk of self-harm and see the organisations in which they work as having a role in responding to individual young people in need. These are encouraging findings that point to at least one strand of a policy in Ghana for addressing the problem of self-harm in young people

Police views of suicidal persons and the law criminalizing attempted suicide in Ghana: A qualitative study with policy implications

The penal code of Ghana condemns suicide attempt. The present study sought to explore the views of the police on persons who attempt suicide and the law criminalizing the act. Qualitative in-depth interviews were used to explore the views of 18 officers of the Ghana Police Service. Data were analyzed using thematic analysis technique. Findings showed that the police officers profiled suicide attempters as needy, enigmatic, ignorant, and blameworthy. Majority (n = 14) of them disagreed with the law and suggested a repeal, whereas only four of them agreed with the law. Regardless of their positions on criminalization, they showed an inclination to help, rather than arrest, when confronted with such persons in line of their duty. Educating the police on suicidal behavior may help to deepen their understanding and help improve the way they handle suicidal persons. This may also strengthen police suicide prevention gatekeeping obligations

Adolescent self-harm in Ghana: a qualitative interview-based study of first-hand accounts

Background: Recent prevalence studies suggest that self-harm among adolescents in sub-Saharan Africa is as common as it is in high income countries. However, very few qualitative studies exploring first-person accounts of adolescent self-harm are available from sub-Saharan Africa. We sought to explore the experiences and first-person perspectives of Ghanaian adolescents reporting self-harm - for deeper reflections on the interpretive repertoires available in their cultural context for making sense of self-harm in adolescents. Methods: Guided by a semi-structured interview protocol, we interviewed one-to-one 36 adolescents (24 in-school adolescents and 12 street-connected adolescents) on their experiences of self-harm. We applied experiential thematic analysis to the data. Results: Adolescents’ description of the background to their self-harm identified powerlessness in the family context and unwanted adultification in the family as key factors leading up to self-harm among both in-school and street-connected adolescents. Adolescents’ explanatory accounts identified the contradictory role of adultification as a protective factor against self-harm among street-connected adolescents. Self-harm among in-school adolescents was identified as a means of “enactment of tabooed emotions and contestations”, as a “selfish act and social injury”, as “religious transgression”, while it was also seen as improving social relations. Conclusions: The first-person accounts of adolescents in this study implicate familial relational problems and interpersonal difficulties as proximally leading to self-harm in adolescents. Self-harm in adolescents is interpreted as an understandable response, and as a strong communicative signal in response to powerlessness and family relationship difficulties. These findings need to be taken into consideration in the planning of services in Ghana and are likely to be generalisable to many other countries in sub-Saharan Africa

Addiction in the Light of African Values: Undermining Vitality and Community

In this article I address the question of what makes addiction morally problematic, and seek to answer it by drawing on values salient in the sub-Saharan African philosophical tradition. Specifically, I appeal to life-force and communal relationship, each of which African philosophers have at times advanced as a foundational value, and spell out how addiction, or at least salient instances of it, could be viewed as unethical for flouting them. I do not seek to defend either vitality or community as the best explanation of when and why addiction is immoral, instead arguing that each of these characteristically African values grounds an independent and plausible account of that. I conclude that both vitalism and communalism merit consideration as rivals to accounts that Western ethicists would typically make, according to which addiction is immoral insofar as it degrades rationality or autonomy, as per Kantianism, or causes pain or dissatisfaction, à la utilitarianism

Organizational justice: A cross-national comparative study of ghanaian industrial workers and their finnish counterparts

The increased globalization in organizations has created the challenge to investigate and understand the organizational behaviours of employees from different cultural backgrounds. The current study investigated organizational justice from a cross-national perspective. Participants were Ghanaian (N = 320) and Finnish (N = 520) industrial workers. Data was collected with Blader and Tyler's (2003) scale. The Ghanaian participants responded to the English version, and the Finnish participants, a Finnish version. The analyses investigated differences on the three justice components (distributive, procedural and interactional). Further analyses examined which of the three best predicts job satisfaction, the relationships between demographic variables and justice perceptions. T-test, correlations, and regression analyses were used to test the hypotheses. Contrary to our expectations, Ghanaian respondents evaluated higher distributive and procedural justice. As predicted, they indicated more sensitivity to interactional justice than their Finnish counterparts. Significant links between all three justice components and job satisfaction were recorded in both samples. Interactional justice indicated the strongest influence. Demographic variables showed more impact on justice perceptions among Ghanaian workers than their Finnish counterparts. The study's theoretical and practical implications are discussed
