Experience and Perpetration of Violent Behaviours among Secondary School Students in Ibadan, Nigeria

Worldwide, adolescents are disproportionately affected by violent behaviours. The nature and extent to which Nigerian adolescents have perpetrated and experienced violence has not been fully investigated. This cross-sectional survey assessed experience and perpetration of physical, sexual and psychological violent behaviours among school-based adolescents. A total of 1366 students (50.4% females and 49.6% males) randomly selected from six public secondary schools in Ibadan, Nigeria were interviewed using a 36-item questionnaire. Respondents answered questions regarding demographic profile, sexual behaviour, and the extent to which they had experienced or perpetrated physical, sexual and psychological violent behaviours. The lifetime experience of at least one of the three forms of violence was 97.9%: physical violence ranked first (94.4%), followed by psychological (77.6%) and sexual violence (34.9%). The most common types of these forms of violent behaviours experienced were slaps (84.5%), unwanted touch of breast and backside (22.7%) and being belittled (63.2%). Approximately 8% of the study group haave had sex and 25% of sexually active respondents claimed that their first sexual encounter occurred in coercive circumstances. The predictors of experience of violence among males were use of alcohol, witnessing domestic violence, involving in work and parental use of alcohol. Among females parental use of alcohol and being young were predictors of violence. Reports of perpetration of physical, sexual and psychological violence among males were 75.3%, 44.9% and 13.3% respectively. Comprehensive interventions targeting students, teachers and parents are recommended to address this problem. Keywords: Adolescents, Nigeria, Sexual behaviours, Violenc

Size composition, growth, mortality and yield of Alectis alexandrinus (Geoffory Saint-Hilaire) in Bonny River, Niger Delta, Nigeria

A twelve month study on the size composition, growth, mortality and yield of Alectis alexandrinus revealed a length range of 11.5 - 33.8 cm (standard length). Employing the length frequency method in the FISAT II package gave the following results for the Von Bertanlanffy growth parameters: L = 35.23, K = 0.680, to = 0.3214 and = 2.926. The total mortality (Z) was 2.47, natural mortality (M) 1.39 and fishing mortality (F) 1.08.The relative biomass per recruit (knife edge selection) was Lc/ L = 0.05, E10 =0.355 and E50 = 0.278. Although the exploitation rate (E) was 0.44 the Emax was 0.421 indicating moderate exploitation of the fish in Bonny River. There is room for increased effort in the fisheries

Incidence, pattern and outcome of renal admissions at the Abia state university teaching hospital, aba: a five year review

The aim of this study was to determine the burden of renal diseases in Aba -a cosmopolitan town in Nigeria undergoing increased urbanization in the last decade. The study involved 359 patient case notes with records of renal diseases between January 2009 and December 2013. Information extracted included age, sex, type of renal disease, length of hospitalization and treatment outcome. Data obtained were analyzed using the statistical package for social sciences (SPSS). The student t-test was used and p < 0.05 was considered statistical significant. The mean age was 53±5.5 years, while the highest incidence was recorded among those aged between 50 - 59 years (23.67%). Majority (56.82%) of the patients were admitted on account of chronic kidney disease with 45.58% of these associated with renal failure. Other associated diseases included nephritic syndrome (11.45), pyelonephritis (7.79%) glomerulonephritis (5.57%), urinary infection (3.06%) and renal stone (1.11%). Mean duration of hospital stay was 12 ± 5 days with 110 (30.64%) deaths. Majority of the dead patients (27.54%) were those with renal failure resulting from CKD. Most of the deaths occurred within 6 days of hospital stay. Thus renal diseases constitute a significant health burden in our community requiring urgent attention.Key words: Renal diseases, admissions, results, Ab

Prevelance and determinants of diagnostic and prognostic disclosure by radiotherapists and surgeons to patients with terminal cancer in Hong Kong

This paper identifies the prevalence and determinants of diagnostic and prognostic information given to terminally ill cancer patients in Hong Kong. Surgeons and radiotherapists (n = 153) were interviewed about the information they gave to their most recently deceased cancer patients. This was explored in relation to doctors' and patients' demographic data, diagnosis, the stage of disease at disclosure, and doctors' attitude. Diagnostic information was disclosed partially in 68% and fully in 46% of cases. Prognosis was disclosed partially in 38% and fully in less than 10% of cases. Determinants of diagnostic disclosure included doctors' attitudes about death, and perceived responsibility for disclosure. The doctor's training and work, and the patient's request for information determined the level of disclosure. After adjustment for a number of social and demographic factors, only the patient's education level remained a significant determinant of the level of prognostic disclosure. A significant proportion of terminally-ill cancer patients do not engage in discussion of diagnosis or prognosis with the doctor caring for them during the last stages of their disease. This reflects the unwillingness to discuss such matters, giving a low priority to information provision, paternalism or other factors, such as little importance being attached to such topics at the late stage of cancer. Thus many cancer patients may fail to learn important information about their disease if they have not engaged in discussion of these topics earlier in their illness. The results of this paper have important implications for medical education in caring for patients with cancer.published_or_final_versio

The design of window shades and fenestration for view clarity

The ability to discern the content of the view through a window is referred to as view clarity. It is often overlooked in the design process, and the methods of shading daylight can affect window views. We conducted a narrative review of building standards and the scientific literature to better understand how shades can be designed so as to retain the window view. View clarity was characterised by three main dimensions: (1) the shading solution, (2) the view content and (3) the observer. Each dimension and the interactions between them influence view clarity. These interactions make it difficult to predict view clarity for all the situations that can occur in buildings. Nonetheless, we highlighted the effects of different shades on the view clarity. Our insights can help designers consider these impacts within the context of overall window design

Aspects of Discrete Breathers and New Directions

We describe results concerning the existence proofs of Discrete Breathers (DBs) in the two classes of dynamical systems with optical linear phonons and with acoustic linear phonons. A standard approach is by continuation of DBs from an anticontinuous limit. A new approach, which is purely variational, is presented. We also review some numerical results on intraband DBs in random nonlinear systems. Some non-conventional physical applications of DBs are suggested. One of them is understanding slow relaxation properties of glassy materials. Another one concerns energy focusing and transport in biomolecules by targeted energy transfer of DBs. A similar theory could be used for describing targeted charge transfer of nonlinear electrons (polarons) and, more generally, for targeted transfer of several excitations (e.g. Davydov soliton).Comment: to appear in the Proceedings of NATO Advanced Research Workshop "Nonlinearity and Disorder: Theory and Applications", Tashkent,Uzbekistan,October 1-6, 200
