The objective of this study was to assess utilization levels, availability, nutritional value, and magnitude of sales by vendors ofDioscorea steriscusby residents of Bindura. A multistage sampling procedure was used to select respondents. Data were subjected to Chi-square, logistic regression, and correlation to determine the effects of demographic determinants on utilization ofD. steriscus. Questionnaires were used to collect data. Results show that education status and period of stay significantly affect the consumption ofD. steriscus(P<0.05). It was also observed that consumption is frequent between lunch and supper (47%) compared to breakfast.D. steriscushas high iron (6.8%), ash (2.06%), and CF (16.8%) contents but it is low in protein (0.83%). Irrespective of gender of respondent, suburb of residence, size of family, period of stay, education level, employment status, and source of income, respondents will growD. steriscusfor use as food supplement (odds ratio = 0.475). The period of stay (r=0.08) and education level (r=0.08) positively affect the growing ofD. steriscus.D. steriscuscan be used as source of energy and can also be used possibly for medicinal purposes. Further study is required on possibility of phytochemicals and cytotoxic components to justify its use.

The COVID-19 pandemic is the first to occur in an age of hyperconnectivity. This paper presents results from an online anonymous survey conducted in Malay, English, and Chinese, during the first week of the Movement Control Order in Malaysia (n=1075), which aimed to examine public knowledge, perception and communication behavior in the Malaysian society in the face of a sudden outbreak and social distancing measures. Although the level of public knowledge, risk perception and positive communication behavior surrounding COVID-19 was high, a majority of respondents reported receiving a lot of questionable information. Multinomial logistic regression further identified that responses to different items varied significantly across respondent survey language, gender, age, education level and employment status.

SummaryThe study assessed adoption of rice post-harvest technologies among smallholder farmers in Osun State, Nigeria. Data were collected from 120 respondents through a structured interview schedule using a multistage sampling procedure. Percentages, means, Chi-square and correlation were used to analyse the data and draw inferences. The results show that about 52.5% of the respondents had favourable perception, while 47.5% had unfavourable perception towards adoption of the rice post-harvest technologies. Rice milling (mean=4.54) and harvesting matured panicles at the right time (mean=4.47) ranked highest among the adopted post-harvest technologies, while majority (65%) of the respondents adopted the rice post-harvest technologies at moderate level and 35% had high level of adoption. Inadequate capital (mean=1.75) and poor extension contacts (mean=1.67) were the major constraints associated with the adoption. Also, there was significant association between sex (χ2= 38.174), marital status (χ2=32.85) and adoption of the rice post-harvest technologies, while age (r=-0.531), household size (r=0.414) and the quantity of rice produced (r=0.345) had significant relationship with adoption of the post-harvest rice technologies. There was moderate level of adoption among the farmers. Financial institutions, governments and non-governmental organisations should provide functional credit facilities and government should employ more extension agents to promote adoption of high-quality enhancing post-harvest technologies for sustainable rice production in Nigeria.

This study aimed to identify types and sites of body injury, location of injury occurrence, and the mechanism and severity of injuries in novice and advanced Brazilian jiu-jitsu (BJJ) athletes. One hundred and eight BJJ athletes took part in this study separated in two groups: advanced (n = 53) and novice (n = 55). Athletes answered a questionnaire concerning regions of injury, locality of occurrence, injury severity and mechanism. Chi square test and a logistic regression analysis were used with the level of significance set at p < 0.05. The main results showed that shoulders and knees were the most injury location reported by novice and advanced athletes. Novice athletes demonstrated higher prevalence of injuries during training sessions (54.5%), whereas advanced athletes reported more injuries during competitions (66.1%). Significant associations between novice and advanced athletes were observed for major joints (p < 0.05). The odds ratio of having injury was 70-87% less for novice versus advanced athletes for the major joints cited. We concluded that BJJ athletes demonstrate high prevalence of injury mainly at knee and shoulder. While risk of injury appeared less in novice, the advanced demonstrated higher number of injuries during competitions as a consequence of injured joint keys. By contrast, novice athletes reported higher number of injuries associated with training sessions as a consequence of overuse.

Background: In Tanzania, like in many other poor African countries, cervical cancer is a major problem facing women especially for those aged 30 years and above. This study aimed at constructing a statistical model to enable the prediction of the outcome of treatment for cervical cancer patients in Tanzania. Methods: Data were collected retrospectively from patient’s files with histological proven cervical cancer who were treated at Ocean Road Cancer Institute (ORCI) from year 2009 and followed up to year 2011. The factors considered are screening status, HIV status, disease stage, age, treatment type and the intent of the treatment. The study employed the Chi-square (χ2) test and the logistic regression model for its analysis. Results:  The Chi-square (χ2) test result showed that there was a significant relationship between outcome of treatment and the patient screening status, HIV status, disease stage and intent of treatment at 5% level of significance. On the other hand, the logistic regression results found patient disease stage and intent of the treatment to be statistically significant at 95 percent. Logistic regression results also showed that patients who attended ORCI when their disease at a late stage had an odds ratio of 0.128 less likely to have favorable outcomes compared to those patients who attended ORCI when their disease stage was at early stages. The odds ratio for cervical cancer patients who received both treatment, radiotherapy, and chemotherapy was 2.643 more likely to have favorable outcomes Conclusion:  More emphasis and campaigns should be made in order to encourage women all over the country to attend cancer centers for screening and treatment at early stages or even before any symptoms for cervical cancer and other types of cancers.

Objective: To evaluate the association between self-reported bruxism and academic performance in students at a university in Lima, Peru. Material and Methods: A total of 203 students were evaluated in this study, between the ages of 19 and 35 years. Self-reported bruxism was measured using the Bruxism Assessment Questionnaire. Academic performance was evaluated using the Approval Index Scale. In addition, other variables were included such as employment status, socioeconomic level, stress, anxiety, among others. The association of variables were factored in using the chi-square test and the logistic regression presented the unadjusted and adjusted analisis. Results: The frequency of self-reported awake bruxism and sleep bruxism was 53.20% and 36.45%, respectively. Evidence revealed there was a statistically significant association between awake bruxism with stress and anxiety, and sleep bruxism with anxiety. Students with high academic performance (OR=2.36; IC del 95%:1.06-5.23) and low academic performance (OR=5.72; IC del 95%:1.28-25.57) were found to be more likely to have awake bruxism than those with medium academic performance. Conclusion: This study revealed a statistically significant association between self-reported awake bruxism and academic performance. However, in the future it is suggested to carry out a study with focus only on students with bruxism and with a larger sample of participants with low academic performance to confirm the association found between these variables.

En el presente estudio pretendimos analizar las características de los autores de agresiones sexuales cuyo modus operandi es el de atacar a la víctima en portales o entradas de garaje de edificios. Nuestro estudio estuvo orientado a determinar si es posible predecir tales características a partir de los datos de la escena del crimen, analizando casos resueltos. Partiendo del contenido de sentencias judiciales condenatorias dictadas en España, y aplicando pruebas estadísticas de chi-cuadrado, odds-ratio, y regresión logística binaria, hemos obtenido resultados alentadores, en el sentido de que algunas de las variables de la escena del crimen permiten predecir algunas características de los autores. Dado que las variables de la escena del crimen utilizadas aquí son conocidas por el equipo policial al inicio de la investigación, la predicción de características del agresor sexual podría ser de utilidad a la hora de priorizar sospechosos.This paper aims at analysing the features of the perpetrators of sexual assaults whose modus operandi consists of assaulting the victim in doorways or entrances of garage and buildings. Its objective was to determine whether it is possible to predict these features moving from the information regarding the crime scene, by means of analysing solved cases. Moving from the content of convicting judgments issued in Spain, and by applying statistical tests of chi-square, odds-ratio, and binary logistic regression, we have obtained encouraging results, in that some variables in the crime scene allow to predict some features of these offenders. Since the variables of the crime scene that have been used here are known to the police team at the beginning of the investigation, prediction of the sexual offender’s features could be useful to prioritize suspects.

This chapter studies user interfaces of Web Online Public Access Catalogs (OPACs) and presents their principal difficulties in facing the man-machine interaction and the contributions of Web 2.0 to overcome these limitations. Methodologies used to study OPACs interfaces are examined. A quantitative approach is used to analyze Web OPACs in academic, special, national, and public libraries through the conclusive use of several tests: chi-square or test of independence, logistic regression, odds ratio, analysis of variance, and discriminant analysis. The situation of Latin American Web OPACs is verified in relation to the use of Integrated Library Systems (ILS) and Database Management Systems (DBMS). This methodology is proposed to study the 2.0 functionalities in these catalogs.

Bovine brucellosis, caused by Brucella abortus, is a serious zoonotic disease manifested by reproductive disorders resulting in huge economic losses to dairy farmers. A random survey was conducted to study the epidemiology of brucellosis in Punjab (India) using sampling software Survey toolbox. Two-stage sampling procedure was adopted; in the first step, villages were selected randomly from sampling frame of all the villages of Punjab followed by selection of owners, and animals in individual farms were identified using random sampling. In all, 32 villages were selected and then 345 animals (approximately 5%) were sampled from these villages. The milk samples collected were screened for brucella antibodies employing ELISA test. The overall apparent prevalence of brucellosis was found to be 18.26% (true prevalence - 17.68%). The prevalence in the central zone of the state was significantly higher, viz. 23.2% (chi square = 11.34, p < 0.01) compared to 14.2% in the sub-mountainous zone and 5.8% in the arid irrigated zone. The disease prevalence was found to be non-significantly higher (chi square 1.029, p = 0.310) in cattle (20.67%) compared to buffaloes (16.41%) and increased with age (chi square = 8.572, p < 0.05) in both species. There was significant association between disease and abortion (chi square = 22.322, p < 0.01) and maximum abortion cases due to brucellosis were found in > 6 month of gestation (95.7%). The disease was significantly associated with the retention of placenta (chi square = 8.477, p < 0.01), however there was no significant relationship of the disease with repeat breeding (chi square = 0.044, p = 0.834). The results of the study suggested that the accurate epidemiological scenario of the disease may be obtained by employing multistage sampling procedures using milk-based ELISA.
