互动在认知建构中的定位

认知在互动过程中不断趋同,又不断分化与超越。互动使各种不同表征的认知系统相互作用,联结建构成具有差异的统一体。在互动过程中,互动个体的认知状态经历了＂初始建构者＂＂孤独建构者＂和＂社会建构者＂三个不同阶段。互动建构的知识并非都是真理。互动所形成的稳定语境,即具有排他性,也具有保护性。权力强加于社会,迫使个体参与权力规训的社会互动,使社会语境发生了根本性的改变,但有时权力无法抗拒原有社会语境从而默认原有社会语境的存在。

Ergonomic recommendations and their role in cardiac sonography

Musculoskeletal disorders (MSDs) have been recognized as a serious hazard to the health and safety of sonographers. Recommendations have been made on ways to reduce and prevent the frequency and severity of these disorders. The purpose of this study was to ascertain the impact ergonomics has had on the prevalence of MSDs among cardiac sonographers. Three hundred randomly selected Registered Diagnostic Cardiac Sonographers were surveyed. Eighty-one respondents completed the survey. The majority of the sample population was female with an average age of 40 and job tenure between 6-15 years. Ninety percent of respondents reported musculoskeletal pain/discomfort while scanning. Seventy-three percent of respondents perceived a need for ergonomic interventions. The majority of respondents were aware of previously recommended ergonomic interventions and had implemented what was feasible. Still, the experience of pain and discomfort, and incidence of MSDs remains exceptionally high for this occupation. It appears that recommended ergonomic interventions have not had a significant impact on improving the health and safety of cardiac sonographers.     

Education and training for social work: A response to Tony Novak

Novak's proposal (1995) that student social workers should be taught on the basis of how social work should be practised rather than how it actually is being practised within the current market economy, is challenged as an unhelpful ‘head in the sand’ approach to current dilemmas in social work education. The revised Diploma in Social Work (CCETSW, 1995a) is defended on the grounds that it prepares social workers for the jobs they will have to do on qualifying; that it retains a user-centred anti-racist and anti-discriminatory value basis and that, in spite of serious political threats, it remains rooted in higher education and emphasises the importance of holistic assessment and critical reflection in practice.

竞争与垄断:近代中国邮政业研究——以福建批信局与国营邮局关系为例(1928—1949)

近代邮政体系建立之前,中国存在官方邮驿和民间邮政两套服务体系。前者18世纪末逐渐衰落,后者则在18世纪中叶快速发展,势力遍布大江南北。中国近代邮政垄断地位的确立与国家支持分不开,以福建批信局为例,国营邮局以管理者和经营者的双重身份,采取各种法律和行政手段,提高邮资、颁布执照并严格管理,限制分号设立和信件自带,严厉打击走私,逐渐掌控批信局及其业务,最终确立了国营邮局在侨批寄递市场的垄断地位,具有浓厚的行政垄断特征。
