Pattern of childhood falls in a low-income setting: a cross-sectional study in Dar es Salaam

The objective was to determine patterns and circumstances of childhood falls in a low-income setting in Dar es Salaam, Tanzania. This cross sectional study is based on a household survey conducted in July 2009. A total of 3927 children up to age 18 from 1928 households in 15 sampled wards were surveyed through a structured questionnaire. The current study includes information regarding fall occurrence, socio-demographic and economic factors. Data were analysed using chi-square, t-test and logistic regression. Male children had 42% higher odds of falls compared to females, and rural residents had more than two times higher odds compared to urban residents. Falls occurred three times more among age group 1-4 and two times more among age group 5-9 compared to those between 15 and 18 years. Most falls occurred outdoors (62%) while playing (51%) with boys being over-represented. Females and children aged 1-4 years fell more from stairs whereas most infants fell from furniture. Male gender, younger age groups and rural residence were significant factors for fall injuries. The circumstances in which these falls occur also differ significantly. Intervention efforts should emphasise these patterns.     

Interweaving threads of credit and debt: Trading (through) textiles in colonial Dar es Salaam

Tracing the modus operandi of textile traders in colonial Dar es Salaam, this article makes a case for viewing the availability and extension of credit in the form of textiles as a central aspect of traders’ lives. The versatility of textiles in the local context of Dar es Salaam not only contributed to their high demand, their use as the main medium of exchange and the basis on which credit was extended; it also shaped the local conceptualisation of entrepreneurship. For textile traders in colonial Dar es Salaam, it was of economic, social and cultural importance to always be both in debt and have others in debt to them.     

Injuries increase the amputee burden at the prosthesis centre: a 2-year retrospective survey of amputees in a low-income setting

The aim of this study is to survey different types of injuries as the cause for prosthesis fitting in the Institute of Physical Medicine and Rehabilitation (IPM&R). This retrospective chart review was conducted at the IPM&R at the Dow University of Health Sciences, from the year 2007 till 2009. We selected all amputees who got enrolled in our institute for prosthesis fitting with major amputations, during the above mentioned period of time. Informed verbal consent was taken from each patient before recording their data at the IPM&R. Anonymity has been maintained. Data for this study was collected through a structured questionnaire, variables included: gender, age, town of origin, cause of amputation, level of amputation, limb involvement (unilateral or bilateral), level and causes of amputations. The data entry and analysis were done on SPSS (Statistical Package of Social Sciences) version 16.0. Of the amputee burden of our study, 55.9% was due to trauma, which is a preventable cause of disability. This is mostly affecting men in the productive age group. New strategies need to be devised in order to alleviate the burden of amputations resulting from preventable injuries.     

Trends and characteristics of injuries in the State of Qatar: hospital-based study

Injuries account for a large burden of mortality and morbidity in the State of Qatar. No comprehensive study has been conducted on all types of injuries in the State of Qatar. The objective of this study was to determine the trend in the number, incidence and pattern of injuries in the State of Qatar. This hospital-based study is a retrospective analysis of 53,366 patients treated at the accident and emergency and trauma centres for injuries during the period from 2006 to 2010. Injuries were determined according to the ICD 10 criteria. The details of the entire trauma patients who were involved in occupational/domestic injuries were extracted from the database of the Emergency Medical Services (EMS), Hamad Medical Corporation. Our results demonstrated that the rates of injury remained relatively stable in the State of Qatar over the five–year period. Those most at risk of injury were non-Qatari males who were below 30 years. Road traffic accidents (RTA) (36.7%) followed by falls causing back injuries (11.0%) were the most common types of injuries during the period. Most of the injuries occurred at the head for both males (17.7%) and females (13.5%); this was consistently the case across all of the age groups. The greatest proportion of RTA (21.2%), industrial machinery injuries (16.4%), construction injuries (15.5%), recreational sporting injuries (20.5%) and beach/sea/ocean injuries (15.0%) resulted in head injuries. Intervention efforts need to be aimed at reducing occupational injuries, RTA injuries and work–related hazards in the State of Qatar.     

Evaluating performance of a Lead Road Safety Agency (LRSA) in a low-income country: a case study from Pakistan

The World Health Organization recommends identifying a Lead Road Safety Agency (LRSA) within the government to coordinate preventive interventions. As LRSAs in developing countries have rarely been evaluated, this case study describes the performance of the LRSA of Pakistan with respect to the World Bank criteria. The designated LRSA, the National Road Safety Secretariat, was put into operation in 2006 and worked for about two years with World Bank funding. The agency had a stand-alone structure headed by an experienced road safety specialist during the first year only and faced difficulty in recruiting other required experts. The LRSA drafted the first National Road Safety Plan, including strategic review of road safety and existing legislation, articulated multisectorial collaboration nationally and provincially, and collected traffic injury data in some districts. Its progress was halted by its dissolution because of funding problems. Currently, two agencies specialising in traffic enforcement and transport research respectively are fulfilling LRSA functions on an ad-hoc basis. Results suggest that sustainability and consistency of LRSAs in developing countries like Pakistan may only be ensured if they are legally protected, inter-ministerial, have permanent funding and are provided with the required expertise through international cooperation, so they can perform their required functions effectively.     

Preventing falls in the elderly living in a deprived area: Evaluation of a community intervention

Statement of the Problem While greatly easing the shopping process for parents, transportation of children in shopping carts also represents a hazard for injuries. Effective accident prevention measures would therefore be desirable. Methods 137 shopping cart-related accidents, the 138 victims of which presented to an Austrian Pediatric Surgical Casualty Department over a period of nine years, were reviewed retrospectively by analysis of the patient charts and of 79 questionnaires returned, correctly filled in, by the family. Results The yearly number varied between 10 and 21 without a falling trend. While 43% of the children were 2 years of age or younger, 18% were older than 4. Three-quarters of the latter had been placed inside the trolley although the maximum permitted weight is 15 kg. Falls out of the trolley comprised two-thirds of all accidents, with the child standing up as the leading cause; these were mostly falls from the basket, followed in almost 20% of cases by toppling over of the entire shopping cart. The youngest children – almost all regularly placed in the integrated seat – were at a special risk for this kind of accident, which frequently occurred in the car park. Lessons learned from the accidents were limited almost exclusively to behavioral changes implemented by the parents. Current European Standards have obviously not taken the main accident mechanisms into account, even though these have repeatedly been described in the literature. Conclusion We believe that technical improvements in the present shopping cart design are desirable to reduce the risk of accidents. Our main suggestions include: solid child seats with integrated footrests, obligatory installation and use of safety belts, and construction of trolleys with a lower center of gravity and a broader wheel base.     

Scope of improvement in water usage efficiency in manual dishwashing: A multicountry study by questionnaire survey

Over recent decades, water conservation have become increasingly an utmost important issue for debate, and this includes the domestic sector. Reducing demand water by improving the efficiency of water use in domestic sector requires an understanding of how water is used and in what ways water savings can be realized. The focus of this global, web‐based, consumer questionnaire survey was to analyze individual consumer attitudes towards using water in manual dishwashing and understand the likelihood of a prospect of changing the daily manual dishwashing method resulting to a more efficient domestic usage of water. This study was designed to investigate the manual dishwashing technique used in the 5249 households of nine different countries ‐ China, Germany, Italy, Russia, Indonesia, Brazil, India, South Africa and Argentina. Besides socio‐demographics, technical questions like cleaning steps, hygiene questions motivational question, environmental awareness questions, questions on payment for water and electricity, questions on information sources about household work were included in the study. It was found that the awareness to conserve water was common among the Asian participants but it necessarily was not practiced in the households as individual washing of dishes was found to be quite high. Among the many outcomes, important one was that ‘running tap method’ was found to be most prevalent (86%) among Russian participants, complimenting their detached approach towards conserving domestic water usage. In South American countries like Brazil (66%) and Argentina (51%), high occurrence of ‘running tap rinse’ was found to be a common practice, confirming the lack of conscious use of water in manual dishwashing in the subcontinent. Based on the overall responses, awareness of a new and efficient technique of manual dishwashing could be propagated through the most voted mediums of Internet (81%) and TV (69%).     

Epidemiology of unintentional child injuries in the South-East Asia Region: a systematic review

All the 11 members of the South-East Asia Region (SEAR) of the World Health Organization are categorised as low- and middle-income countries. This region has over a quarter of the world's total population but comprises about one-third of the world's unintentional injury-related deaths. There is a paucity of good-quality mortality and morbidity data from most of these countries. This is the first systematic review of community-based surveys on child injuries that summarises evidence from child injury studies from the SEAR countries. The included papers reported varying estimates of overall non-fatal unintentional injury rates across the countries, from 15/1000 children in Thailand to as high as 342/1000 children in India. The fatal injury rates were also found to be varying. This review revealed a need for strengthening child injury research using standard methodologies across the region and for promoting the dissemination of the results.     

Dimensions of expatriates adjustment in distant subsidiaries: A field study of a sub‐Saharan African institutional distance

The aim of this study is to investigate the determinants of expatriates’ adjustments in distant and complex multinational subsidiaries. Using the institutional theory as a basis for expatriates’ assignments in complex subsidiaries, the work employed a sequential mixed methodology of data collection. An in‐depth face‐to‐face interview with 21 senior expatriate executives and a quantitative survey of 204 expatriates working in various multinational subsidiaries in Ghana served as data for the work. Consequently, a structural equation modeling (SEM) and a content analysis were the basis of the data analysis. Findings showed host country culture plays a significant role in determining expatriate adjustment in distant subsidiaries. Findings also showed expatriates’ competence in cross‐cultural communication significantly determines expatriates’ adjustment in distant subsidiaries. The work recommends an intensive training of expatriates in cross‐cultural communication and host cultural values and behaviors for international assignees.     

Epidemiology of yoga-related injuries in Canada from 1991 to 2010: a case series study

The aim is to describe the epidemiology of yoga injuries presenting to select Canadian emergency departments (EDs). Those who presented with a yoga injury to a Canadian ED participating in the Canadian Hospitals Injury Reporting and Prevention Program and had completed a data collection form between 1991 and 2010 were included. Demographic and injury characteristics were tabulated and injury profiles of children were compared to adults. Sixty-six individuals (48 female, 18 male) who sustained 67 injuries were included. The median age was 19 (intraquartile range: 13, 32) and 73% of individuals were injured after 2005 (p = 0.0003). Sprain was the most common injury (23/67, 34%) and the most common body region injured was the lower extremity (27/67, 42%). Significantly more children were injured while being instructed than adults (p = 0.003) but more adults required treatment (p = 0.023). Although yoga-related injuries presenting to an ED are not common, the number of injuries are increasing.     

Cross-cultural study of channel relationship factors — Antecedents of satisfaction in a retail setting: A commentary essay

Channel relationships within and across diverse markets have been investigated for quite some time. Yet findings from these studies over the last forty years or so have been far from conclusive. Channel researchers Runyan, Sternquist, and Chung (forthcoming) investigate interrelationships between the behavioral constructs of role performance, dependence, conflict, satisfaction, and influence strategy in the U.S. and Japanese context. Reading this paper leads credence to the adage, “The more things change, the more they stay the same.” Indeed, a review of representative comparative channels research literature from the 1980s and post-2000 brings to surface striking similarities in terms of shaky conceptual frameworks, less than robust construct measures, and insufficient caveats in explaining and applying research findings. For channels research to gain relevance in today's globalized marketplace, greater sophistication is necessary in formulating and implementing comparative studies. An overarching framework is necessary to explain, if not incorporate, similarities and differences in channel interactions around the globe.     

A machine-learning method for improving crash injury severity analysis: a case study of work zone crashes in Cairo,Egypt

Abstract

The quality of vehicular collision data is crucial for studying the relationship between injury severity and collision factors. Misclassified injury severity data in the crash dataset, however, may cause inaccurate parameter estimates and consequently lead to biased conclusions and poorly designed countermeasures. This is particularly true for imbalanced data where the number of samples in one class far outnumber the other. To improve the classification performance of the injury severity, the paper presents a robust noise filtering technique to deal with the mislabels in the imbalanced crash dataset using the advanced machine learning algorithms. We examine the state-of-the-art filtering algorithms, including Iterative Noise Filtering based on the Fusion of Classifiers (INFFC), Iterative Partitioning Filter (IPF), and Saturation Filter (SatF). In the case study of Cairo (Egypt), the empirical results show that: (1) the mislabels in crash data significantly influence the injury severity predictions, and (2) the proposed M-IPF filter outperforms its counterparts in terms of the effectiveness and efficiency in eliminating the mislabels in crash data. The test results demonstrate the efficacy of the M-IPF in handling the data noise and mitigating the impacts thereof.
