影响农民工职业安全健康需求的自身因素分析

农民工群体为国家经济发展做出了重要贡献,但其职业安全健康状况却令人担忧。通过文献整理发现,农民工自身职业安全需求低是造成这种现象的重要原因之一。从农民工自身角度来分析,来自以下四方面的原因共同制约着农民工对职业安全的需求：（1）农民工知识结构欠缺、工作年限普遍较短、缺乏对职业安全的认知意识,影响农民工对职业危害的认知;（2）来自家庭的增收压力和降低寻找工作的间接成本的要求造成了目前农民工经济压力大的状况;（3）自身技能水平较弱以及缺乏对就业信息的分析能力,削弱了他们的就业竞争力;（4）农民工群体之间缺乏沟通信任以及长期的低社会地位限制了他们的谈判能力。以上四方面原因相互作用,产生效力叠加,共同导致了目前农民工职业安全需求不足的状况。     

Evolution of worker sterility in honey-bees (Apis mellifera): how anarchistic workers evade policing by laying eggs that have low removal rates

In anarchistic honey-bee colonies, many workers’ sons are reared despite the presence of the queen. Worker-laid eggs are normally eaten by other workers in queenright colonies. Workers are thought to discriminate between queen-laid and worker-laid eggs by the presence or absence of a queen-produced egg-marking pheromone. This study compared the survival of three classes of eggs (worker-laid eggs from anarchistic colonies, worker-laid eggs from non-anarchistic queenless colonies, and queen-laid eggs) in both queenright normal colonies and queenright anarchistic colonies, in order to test the hypothesis that anarchistic workers evade policing by laying more acceptable eggs. As expected, few worker-laid eggs from non-anarchistic colonies survived more than 2 h. In contrast, worker-laid eggs from anarchistic colonies had much greater acceptability, which in some trials equalled the acceptability of queen-laid eggs. Anarchistic colonies were generally less discriminatory than normal queenright colonies towards worker-laid eggs, whether these originated from anarchistic colonies or normal queenless colonies. This indicates that the egg-removal aspect of the anarchistic syndrome involves both worker laying of eggs with greater acceptability and reduced discriminatory behaviour of policing workers.

Metal Interactions in carcinogenesis†

Mixed exposures to a number of metallic compounds may give rise to a carcinogenic response in humans.

An interaction between occupational exposure to arsenic and cigarette smoking has been documented epidemiologically. A multiplicative effect was indicated concerning the occurrence of lung cancer when both of the exposures were present. Several experimental studies have been reported in the literature concerning interactions between benzo(a)pyrene and Fe₂O₃ as well as some other metallic compounds like Ni₃S₂, PbO, MgO and TiO₂ in relation to respiratory carcinogenicity. There is also limited evidence of a positive interaction between arsenic trioxide and benzo(a)pyrene. Particles containing V and Ni were obtained from the flue gases of power plants burning heavy fuel oil. Such particles were not carcinogenic themselves but enhanced the carcinogenicity of benzo(a)pyrene even more efficiently than Fe₂O₃.

Increased dietary selenium intakes can decrease the carcinogenicity of several organic carcinogens in animals and dietary zinc can effectuate both enhancement and inhibition of carcinogenicity depending on dietary concentration.     

Occupational accident: An example of fatalistic beliefs among medical waste workers in Bangladesh

This study was conducted to see whether fatalism is an important factor in explaining occupational accidents among medical waste operatives in Dhaka, Bangladesh. Data were collected using a variety of qualitative techniques and included observation, formal and informal dialogue. Sampling strategies included formal representative sampling, purposive and authoritative sampling. Employers did not supply PPE or offer training to their staff. Most workers (73%) did not wear PPE regularly, and a further 18% wore only insufficient PPE. Consequently, most waste workers (95%) reported that they had experienced occupational accidents, mostly (75%) from used needles and other sharps. These observations were associated with fatalistic beliefs among the participants, both managers and employees, who attributed these events to “fate” reflecting their perceived lack of control over such accidents. This study reveals many examples of a lack of organisational awareness that can occur within a culture of fatalism.     

Cultural influences on workplace safety: An example of hospital workers’ adoption of patient lifting devices

Aims

A sociological and anthropological view of culture was used to investigate how work culture, independent of “safety culture”, may affect safety in the workplace. We explored how work cultures of nurses and physical/occupational therapists (PT/OTs) in two acute care hospitals are related to the adoption of patient lifting devices.

Methods

Focus groups were conducted between 2006 and 2009, seven with nurse staff (n = 39) and two with PT/OT staff (n = 17), to explore issues concerning a Minimal Manual Lift Environment policy, initiated in 2004, and subsequent use of patient lift equipment. Audio recordings of the sessions were transcribed; text data were analyzed using N6-QSR. Cultural facilitators and barriers to the adoption of patient lift equipment were examined.

Results

Data revealed cultural similarities and differences between these healthcare professions. Both displayed a “patient first” approach to care-giving which may promote lift device use for patients’ benefits, not necessarily for staff safety. Also, the implied purpose of patient lifting devices clashes with the nurses’ cultural emphasis on compassion, and with PT/OTs’ cultural emphasis on independence except when use increases patients’ independence.

Conclusions

Cultural expressions regarding the nature of care-giving among healthcare professionals may affect the propensity to adopt safety measures in complex ways. The workers’ understanding of the purpose of their work, and acceptable means of conducting it, should be understood before implementing safety interventions. The utilization of lift assist teams, who are not socialized into the cultures of nursing or PT/OT, may be one means of circumventing cultural barriers to lift equipment use.     

An evaluation of occupational accidents in the wooden furniture industry - A regional study in South East Asia

Studies on the rate of occupational accidents among workers in the wooden furniture industry is sparse, although the industry is deemed to be highly accident prone. Therefore, the rate of occupational accidents among workers in the wooden furniture industry in Malaysia, Thailand, Indonesia and Vietnam were studied, in 240 furniture manufacturing factories, using a structured questionnaire. The findings of the study suggest that contract workers are less prone to occupational accidents compared to their permanent counterparts, and hence, are more productive. Further, the results also revealed that the contract workers have a more positive attitude towards the work, and hence, pick up the essentials of safe working practices quickly. It must therefore be recognized that the “production oriented mentality” prevalent in the wooden furniture industry, which has been argued to compromise occupational safety and health standards in the industry may be debatable. In this context, it is essential for the policy makers to re-examine the employment of contract workers for the furniture manufacturing industry, as changing the psycho-economic parameters of the industry may be warranted before the industry is deemed attractive to a permanent workforce.

Political drivers of epidemic response: foreign healthcare workers and the 2014 Ebola outbreak

This study demonstrates that countries responded quite differently to calls for healthcare workers (HCWs) during the Ebola epidemic in West Africa in 2014. Using a new dataset on the scale and timing of national pledges and the deployment of HCWs to states experiencing outbreaks of the virus disease (principally, Guinea, Liberia, and Sierra Leone), it shows that few foreign nations deployed HCWs early, some made pledges but then fulfilled them slowly, and most sent no HCWs at all. To aid understanding of such national responses, the paper reviews five theoretical perspectives that offer potentially competing or complementary explanations of foreign government medical assistance for international public health emergencies. The study systematically validates that countries varied greatly in whether and when they addressed HCW deployment needs during the Ebola crisis of 2014, and offers suggestions for a theory‐driven inquiry to elucidate the logics of foreign interventions in critical infectious disease epidemics.
