Work-related upper extremity injuries: prevalence,cost and risk factors in military and civilian populations

Persons with musculoskeletal-related disorders represent a prevalent source of outpatient visits, lost work time and disability in the military; however, research concerning the extent of work-related upper extremity disorders (WRUEDs) within this population is lacking. This literature review examined studies in civilian and military settings to ascertain the prevalence, cost and risk factors associated with WRUEDs. The results indicated that the prevalence and cost of WRUEDs in the civilian workforce are significant, justifying the need to research the military population. The literature also outlined physical, individual and psychosocial factors associated with WRUEDs that will help identify potential risk factors within military occupations.     

The impact of the Arab Spring on democracy and development in the MENA region

In evaluating the consequences of the Arab Spring 8 years later, this paper not only focuses on the short‐term consequences of the uprisings that swept through a number of countries in the Middle East and North African region but also analyzes the long‐term prospects for democratization and development in the MENA region. The impact of the Arab Spring, despite its promises and the expectations of the rest of the world, has been dismal. While only Tunisia made a successful transition to a democratic polity with a constitution guaranteeing the basic rights of the people, the rest of the Arab Spring countries remain in the grip of the authoritarian rule, and countries such as Syria, Libya, and Yemen have been degenerated into bloody civil wars with dwindling hope of peace and freedom. On economic front, the growth has been tardy, showing little difference with countries that were unaffected by the Arab Spring. Yet, the paper concludes, echoing historian Eric Hobsbawm's view, that revolutionary outcomes need not be judged as failure too quickly as they are likely to be partial success in the long term. The impact may be observed in the area of social opening, newer class alliances, and the emergence of a less rapacious, reformed, hybrid authoritarianism.     

Ergonomics in a hospital and a university setting: The effect of worksite analysis on upper extremity work-related musculoskeletal disorders

OBJECTIVES: The purpose of this study was to determine whether individuals with work-related injuries receiving worksite analysis would have less lost workdays than individuals not receiving worksite analysis. Therapeutic management of work-related injuries in a hospital and a university setting were also compared. STUDY DESIGN: Over a one-year period, employees who sustained an upper extremity work-related injury were issued questionnaires regarding their injury, treatment, functional status and pain level. Participants were divided into three groups: group 1 consisted of hospital employees (N=14) who underwent worksite analysis, group 2 included university employees (N=15) who underwent worksite analysis whereas group~3 included university employees (N=14) who underwent no analysis. RESULTS: All groups were similar in demographics, functional status, and pain level. Satisfaction with the worksite analysis was similar for groups one and two. CONCLUSION: A pattern of less absenteeism but greater modified duty days was associated with those individuals undergoing worksite analysis.     

The use of a vertical arm support device to reduce upper extremity muscle firing in sonographers

Work-related musculoskeletal disorders (WRMSD) in sonographers have increased over the past 20 years with shoulder injuries being the most prevalent. Advancing ultrasound technologies have reduced a sonographer's need to move when performing exams and increased prolonged arm abduction, resulting in static work postures and decreased joint perfusion. Work modifications in other industries have demonstrated that reducing arm abduction to 30° reduces muscle firing and fatigue. Although this is the ideal work posture for sonographers, there are many instances in which excessive arm abduction and static postures cannot be avoided. These positions are further complicated by the fact that the scanning arm is also supporting the weight of the ultrasound transducer. This observational case study evaluated the use of a moveable arm support system as a means to provide support for the scanning arm and reduce muscle firing during ultrasound exams in the scanning lab of a university diagnostic ultrasound educational program.     

Correlations in between EAWS and OCRA Index concerning the repetitive loads of the upper limbs in automobile manufacturing industries

Upper limbs repetitive tasks are one of the main sources of risk for the workers of the manufacturing industries and the standards ISO 11228-3 and EN 1005-5 addressed this issue since 2007. EAWS (European Assembly Worksheet) is a 1st level ergonomic risk assessment method and it provides in its 4th section a score to measure the load level for the upper limbs based on a traffic light scheme. According to the relevant ISO/CEN standards, the OCRA Index is the preferred system to refer to in the evaluation of the biomechanical stress of hand-harm-shoulder system. This correlation study is based on a 45 workstations sample coming from the automobile manufacturing industry. According to the results, EAWS4 shows an excellent correlation with OCRA index (Spearman's rho correlation index 0.95). Being EAWS based on biometric statistical data distribution, its typical application is the process design phase, but adopting a conservative approach in the interpretation of EAWS4 score for risk mapping purposes, it provides an equivalent "reaction" pattern (countermeasures to be taken in the production phase) with respect of OCRA Index with an Odds Ratio ranging from 0.89 (OR-matched) to 1.00 (OR-conservative).     

The effects of smoking laws on seating allocations of restaurants, bars, and taverns

Supporters of smoking laws often argue that they do not harm restaurants, bars, and taverns and may even raise their profits. Opponents argue that owners cater to customer preferences regarding smoking and that laws mandating specific smoking policies will therefore negatively impact profits of some firms. This article tests hypotheses regarding how smoking laws affect seating allocations, using data from a nationwide survey of restaurant and bar owners. The empirical evidence indicates that smoking laws exert no significant effect on seating allocations. Firms are shown to allocate greater shares of seating to nonsmoking use when customers exhibit stronger preferences for such seating.     

The impact of a health campaign on hand hygiene and upper respiratory illness among college students living in residence halls

Hand hygiene is a key element in preventing the transmission of cold and flu viruses. The authors conducted an experimental-control design study in 4 campus residence halls to determine whether a message campaign about hand hygiene and the availability of gel hand sanitizer could decrease cold and flu illness and school and work absenteeism. Their findings indicate that students who were exposed to the message campaign and provided with gel hand sanitizer increased their knowledge about the potential health benefits of hand washing and sanitizer use; they reported higher rates of hand washing and using sanitizer than did the control group. These students also experienced fewer cold and flu illnesses during the study than those in the control group and missed fewer class or work engagements because of colds or flu. Conducting a health promotion campaign in residence halls may therefore help prevent colds and flu and decrease absenteeism on university campuses.     

The impact of emigration on national development in the Arab region: the case of the Yemen Arab Republic

"The focus of this article is the impact of emigration on national development in labor sending countries experiencing wide-scale emigration, the main contention being that, due to the characteristics of contemporary labor movements among Arab countries, there obtains a contradiction between short term benefits and long term adverse effects. The article briefly defines development, then presents empirical evidence from the Yemen Arab Republic of the negative impact of labor emigration."     

Lost in space: The impact of sensorimotor difficulties on emotional and social development in early childhood

This article examines the impact of sensorimotor deficiencies on social and emotional development in childhood. Children who have impairments in processing and coordinating sensory experience are unable to sufficiently develop sensorimotor schemas. Sensorimotor learning, in part, creates the experimential domain of the emergent self and is also a necessary component of core self development as outlined by Daniel Stern. The impact of deficiencies on the core self and, therefore, on social and emotional development are demonstrated with a complicated case example. The treatment process highlights the possibility of reworking core self issues and their effects on self concept and relationships. Multidisciplinary treatment is required to fully address all deficits. The child psychotherapist's role is to attend to the emotional and relational issues, as well as to coordinate the work with family and school.is on the editorial board of theClinical Social Work Journal, is on the faculty of the Institute for Clinical Social Work, and is in private practice.

Dual language input and the impact of language separation on early lexical development

We examined properties of the input and the environment that characterize bilingual exposure in 11‐month‐old infants with a regular exposure to French and an additional language, and their possible effects on receptive vocabulary size. Using a diary method, we found that a majority of the families roughly followed a one‐parent–one‐language approach. Yet, the two languages co‐occurred to various extents within the same half‐hour both within and across speakers. We used exploratory correlation analyses to examine potential effects of the dual input on the size of infants’ vocabularies. The results revealed some evidence for an impact of language separation by speakers.     

Occupational musculoskeletal injuries in the health care environment and its impact on occupational therapy practitioners: a systematic review

The purpose of this systematic review was to explore the occupational and personal factors associated with occupational musculoskeletal injuries among health care providers and to identify the psychosocial issues as a result of the injuries. Then, an extrapolation developed to link the potential risks to occupational therapy practitioners. The inclusion criteria that developed from ten articles was based on content from the health and social science literatures. Searches were conducted via internet databases, hard-copy search of bibliographies, and citation review of article references. This review included 22 research studies over the past fifteen years (1990-2005). Classic scientific research studies and classical readings that went beyond the specified period were also included. The review revealed that patient handling was the most common occupational factor to cause work-related injuries. Inexperience and young age were major personal factors associated with injuries. Fear, anger, isolation, inability to perform duties and leisure activities were common psychosocial issues as a result of the injuries. It was extrapolated that occupational therapy practitioners were at risk for occupational musculoskeletal injuries. Future studies are recommended to examine the prevalence and risk factors specific to occupational therapy practitioners.     

A panel data analysis of the impact of trade on human development

Arguments for a positive link between trade and per-capita income are often met with the counterargument that “there is more to life than income”—the implication being that trade improves income, but degrades “quality of life.” In this paper, we attempt to address this counterargument by examining the impact of trade on countries’ social developments as measured by the Human Development Index (HDI)—a composite measure of education, literacy, and income published by the United Nations Development Programme. Utilizing a generalized method of moments (GMM) procedure in a panel data framework, we find that increases in trade are positively associated with future increases in social welfare.     

The relationship between international law and European labour legislation and its impact on the development of international and European social law

This article draws on observations of how European Union law takes account of international worker protection instruments and the activities of international organizations to protect social rights to establish a typology of the links – often close but also very diverse – between European law and “international labour law” in the broad sense.     

Homelessness as one component of housing instability and its impact on the development of children in poverty

The number of families with children living in poverty and experiencing housing instability and homelessness has increased dramatically over the last two decades. Current public policy decisions will lead to further increases. Understanding the impact of this instability on the emotional, behavioral, and cognitive development of children is imperative. Few studies critically examine the effects of instability on both domiciled and homeless children. This research examined the effects of homelessness and housing instability on 133 children 8 to 12 years of age living in poverty. Results indicate that whether a child is currently homeless is not as significant as overall stability which may have a long ranging effect on a child's future development.     

The impact of electronic land administration on urban housing development: The case study of the Federal Capital Territory of Nigeria

This paper evaluates the impact of electronic land administration as an e-government policy initiative in Nigeria. It analyses conceptually the differences between the expected and actual value of Abuja Geographic Information Systems (AGIS)—an e-land administration project—on urbanisation in Abuja, the Federal Capital Territory (FCT) of Nigeria. The AGIS case study reveals that differences between the expected and actual value of strengthening the state’s financial capacity are low. The differences are medium for enhancing access to and security of credit, and improvement of land use planning and environmental management and high for the promotion of popular participation. The elicited differences are traceable to hindrances inscribed in Land Use and National Housing Acts, to inequitable access to land, inconsistent resettlement policy, poor community participation and financial misconduct. The findings suggest the need to pay attention to provisions through which e-government can support the reduction of country specific problems, improve the quality of institutions and to promote urbanisation, thereby increasing social welfare as well as participation by the people in promoting suitable and adequate shelter for all citizens.
