How does education influence adolescents’ endorsement of conspiracy theories? examining the roles of critical thinking, literacy, justice perceptions and identification with society
Money, value and the state
Money, Value and the State is about how currency management was used in the first years of independence in East Africa to try to shape people's economic behaviour to help meet the state's aims, and the ways in which people resisted these measures when they felt their best interests were not served by them.During the initial years of independence, the global economic context was relatively favourable, but even then, there was always a gap between …

The Impact of Heterosexual Scripts on Women’s Sexual Desire in Relationships
The Reflective Mind of the Anxious in Action
The Attentional Control Theory (ACT) posits that, while trait anxiety may not directly impact performance, it can influence processing efficiency by prompting the use of compensatory mechanisms. The specific nature of these mechanisms, which might be reflective, is not detailed by the ACT. In a study involving 110 students (M = 20.12; SD = 2.10), surveys were administered to assess the students’ metacognitive beliefs, trait anxiety, and emotion r…

Trait Anxiety, Emotion Regulation, and Metacognitive Beliefs
Trait anxiety, emotion regulation strategies, and metacognitive beliefs influence executive functions (EFs) and academic achievement. This study examines their interplay and impact on academic success. In total, 275 adolescents (10-17 years) and parents completed an online questionnaire assessing trait anxiety, emotion regulation strategies, metacognition, parent-reported behaviors related to executive functioning, and overall school average. Pre…
Cross-sectional and longitudinal associations between self-esteem and BMI depends on baseline BMI category in a population-based study
Our findings suggest that the association between self-esteem and BMI depends on the initial category of BMI, with a negligible effect of self-esteem
Development and validation of the mindful eating scale (mind-eat scale) in a general population
Self-compassion and emotion regulation
Self-compassion (SC) seems to play an important role in improving Emotion Regulation (ER). Nevertheless, the results of previous studies regarding the links between SC and ER are not consistent, especially facing diverse models of ER (strategy-based vs skill-based). The goal of this prospective study was to evaluate the links between these three concepts, by testing the predictive roles of SC and ER skills on both ER adaptive and maladaptive stra…
Dimensional model on how familial vulnerability and environmental factors impact transitional age youth psychopathology
This study findings allowed to present a predictive dimensional model on TAY psychopathology, including belonging to a clinical population at transitional age, childhood trauma, and family dysfunction. Further research is needed to replicate Transition_psy study results in other samples. The proposed model could be used in clinical practice to improve assessment of TAY psychopathology
Positions on science and religious beliefs across societies
Science education inclusive of learners’ cultures requires understanding how students position scientific knowledge with regard to identity-laden beliefs, such as religions. To address this need, we developed a research tool administered across linguistic and societal contexts. In this article, we present the conceptual frameworks the instrument articulates and draws upon. We then test the construct validity and internal consistency of its dimens…
Validation of the Flexible and Rigid Cognitive Restraint Scales in a General French Population
Distinguishing between flexible and rigid cognitive restraint (CR) may be useful for understanding the role of CR in dietary behavior and weight status. This study aimed to translate and adapt the flexible and rigid CR scales to the French context and test their psychometric properties. Construct validity, internal consistency, and test-retest reliability were examined in a sample of 620 individuals. Confirmatory factor analysis of the scales fou…
Resilience Is Associated with Less Eating Disorder Symptoms in the NutriNet-Santé Cohort Study
Resilience is a positive psychological trait associated with a lower risk of some physical and mental chronic diseases and could be an important protective factor against eating disorders (EDs). The aim of this study was to assess cross-sectional and longitudinal associations between resilience and ED in a large cohort of French adults. In 2017, a total of 25,000 adults from the NutriNet-Santé cohort completed the Brief Resilience Scale (BRS). ED…
Empowering Well-Being
Study Protocol
Introduction: Emerging adults are a particularly at-risk population in mental health. The primary aim of the Transition_psy study is to evaluate changes in mental health care need and quality of life during transition from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS). The relationship between these changes and genetic or environmental vulnerabilities and clinical dimensions representing risk and prote…
Self-Compassion and Rumination Type Mediate the Relation between Mindfulness and Parental Burnout
The COVID-19 lockdown increased the day-to-day challenges faced by parents, and thereby may have increased parental burnout risk. Therefore, identifying parental burnout protection factors is essential. This study aimed to assess the protective role of the following factors which can be increased through mindfulness practice: trait mindfulness, self-compassion, and concrete vs. abstract ruminations. A total of 459 parents ( M age = 40; 98.7% fema…
Gratitude Moderates the Relation between Daily Hassles and Satisfaction with Life in University Students
Satisfaction with life as a judgmental cognitive process can be negatively influenced by appraisals of daily events such as hassles. Trait-gratitude-a tendency to appraise, recognize and respond to life events through being grateful-is a determinant of mental health and well-being, and has been shown to be related to the positive appraisal of life. The aim of the current study was to investigate the moderating role of trait-gratitude in the relat…
Resilience Predicts Lower Anxiety and Depression and Greater Recovery after a Vicarious Trauma
This study validated the French version of the Brief Resilience Scale (BRS-F) and tested the protective role of resilience in the context of vicarious trauma (22 March 2016 terrorist attacks in Brussels) regarding anxiety and depression symptoms. Confirmatory factor analyses indicated a single-factor structure of the BRS-F. Investigation of convergent validity showed that the BRS-F was positively correlated with usual outcomes such as subjective …
Trauma awareness and preparedness
This study examined influences of trauma awareness and preparedness on the development of posttraumatic stress disorder (PTSD) in civilian and military personnel with exposure to the civil war. Participants were 302 people with exposure to civil war in the Democratic Republic of Congo (civilians = 68%; females = 47%; age range = 16 to 76 years old, SD = 13.58 years). Participants completed the Posttraumatic Checklist Scale, General Self-Efficacy …
Capital Accumulation, Class Formation and Dependency-The Significance of the Kenyan Case
The aim of this paper is to clarify some of the issues that have been posed in the theoretical debate about and to reconsider the evidence from Kenya in the light of this clarification-if possible, carrying the discussion a small step further in the process. The most important question of all those which are at stake in the debate about is whether or not there are theoretical reasons for thinking that the ex-colonies cannot (as Marx put it) adopt…

What is The Problem About Corruption
The systematic investigation of corruption is overdue. There are three main types of literature in English on the subject: historical studies of corrupt practice in Britain; inquisitional studies, mainly of the U.S.A. and the English-speaking West African and Asian countries; and sociological studies which deal with corruption incidentally. So far as I know no general study in English has appeared.1 One reason for this seems to be a widespread fe…

The 'overdeveloped' post colonial state
In this article Leys questions some of the formulations on the post-colonial state and its bureaucracy developed by Hamza Alavi, Roger Murray and John Saul. The articles referred to are Alavi's 'The State in Post-Colonial Societies' (New Left Review, 74, July/August 1972) and Murray's 'Second Thoughts on Ghana' (New Left Review, 42, March/April 1967). But Leys is particularly concerned to open a debate on John Saul's 'The State in Post-Colonial S…
Politics in Kenya
The central question which this article attempts to raise is how we should understand the social structure that is emerging from the neo-colonial pattern of change in Africa, and what implications it has for politics. In its simplest form, the question is how far a stratification system is developing which is likely to make for class formation, class consciousness, and a politics of class struggle; or how far stratification can be contained withi…

Liberation without democracy? the Swapo crisis of 1976
This article examines the internal convulsions that racked the Namibian liberation movement, Swapo, in Zambian exile in the mid‐1970s. This was a crisis that saw the Zambian army link up with the Swapo leadership to arrest, as ‘dissidents’, well over a thousand of the movement's cadres. Often misleadingly labelled ‘the Shipanga crisis’ (because of the alleged central role in the events of then senior Swapo leader Andreas Shipanga) the crisis actu…

Intellectual Mercenaries and the Public Interest
English Throughout the 1990s developments in the NHS have been largely driven by the efforts of hospital trusts and health authorities to find ways of surviving in the face of constant financial shortfalls. Because NHS regional offices no longer provide them with planning expertise, they rely instead on private sector management consultants. This article describes the NHS market for advice and the predominantly market-orientated attitudes that ma…

The End of Parliamentary Socialism
Lubango and After
This article examines the considerable efforts made by some Namibians (notably the 'Breaking the Wall of Silence' committee) throughout the 1990s to keep alive the issue of the Swapo leadership's alleged abuses of power when in exile. These activists' key focus has been the torture and killing of many innocent cadres (labelled 'spies') of Swapo in the movement's detention centre at Lubango, Angola, in the 1980s. The article reviews the difficulti…
Sub-Saharan Africa in Global Capitalism
If we define sub-Saharan Africa as excluding not only north Africa but also bracket off, for the moment, the continent's southern cone, dominated by South Africa, the key fact about the rest—the greater part of the continent—is thrown sharply into relief: after 80 years of colonial rule and almost four decades of independence, in most of it there is some capital but not a lot of capitalism. The predominant social relations are still not capitalis…

The report of the resulting mission of 26 experts ran to 600 pages and was published in November 1972.1 As was to be expected, it provided an immense quantity of invaluable information. More important, it placed public discussion of the problem, and indeed of the wider issue of the nature of t…

University of East Africa Conferences on Public Policy
These conferences grew out of the new University's desire to offer more direct assistance for the development of East Africa. The objects were: (1) to provide a forum for political leaders from all the East African countries and from some others, in which they could discuss matters of major public policy in an objective and private atmosphere; (2) to provide a series of opportunities for these leaders to meet and gain a deeper understanding of ea…

The Professional Study of New Nations
The four books reviewed herei convey some useful information, and two of them contain some interesting and even important ideas. Their collective message is, however, that we still have a very long way to go in creating a really professional literature on the new nations, and they remind us how extremely difficult financially expensive, intellectually taxing, and organizationally complex such an enterprise is. Professor Mair's synthesis is, in re…
Tanganyika. The Development of its Laws and Constitution
Recent Relations between the States of East Africa
In the Nairobi Declaration of June 1963 the political heads of the three East African mainland states publicly committed themselves to federation; in June 1965 they were beginning to prepare the public for a substantial reduction in the area of functional co-operation that had been established prior to 1963. With the wisdom of hindsight we can perhaps see that the reasons for this development are fairly obvious. This paper chronicles some of them…

Incentive and Development
The justification for reviewing this book* four years after its publication is that it makes ambitious claims, yet has not been widely noticed outside a fairly limited professional circle, and mainly in the United States. It aims to prove that there is one factor in economic growth more important than all others, which if it could be established, and if the factor were at all liable to manipulation, would be a discovery at least as important as t…
