‘Age-hardened alloy’ based on bulk polycrystalline oxide ceramic

We report here for the first time the development of ‘age-hardened/toughened’ ceramic alloy based on MgO in the bulk polycrystalline form. This route allows for the facile development of a ‘near-ideal’ microstructure characterized by the presence of nanosized and uniformly dispersed second-phase particles (MgFe₂O₄) within the matrix grains, as well as along the matrix grain boundaries, in a controlled manner. Furthermore, the intragranular second-phase particles are rendered coherent with the matrix (MgO). Development of such microstructural features for two-phase bulk polycrystalline ceramics is extremely challenging following the powder metallurgical route usually adopted for the development of bulk ceramic nanocomposites. Furthermore, unlike for the case of ceramic nanocomposites, the route adopted here does not necessitate the usage of nano-powder, pressure/electric field-assisted sintering techniques and inert/reducing atmosphere. The as-developed bulk polycrystalline MgO–MgFe₂O₄ alloys possess considerably improved hardness (by ~52%) and indentation toughness (by ~35%), as compared to phase pure MgO.     

Do Student Evaluations of University Reflect Inaccurate Beliefs or Actual Experience? A Relative Rank Model

It was shown that student satisfaction ratings are influenced by context in ways that have important theoretical and practical implications. Using questions from the UK's National Student Survey, the study examined whether and how students' expressed satisfaction with issues such as feedback promptness and instructor enthusiasm depends on the context of comparison (such as possibly inaccurate beliefs about the feedback promptness or enthusiasm experienced at other universities) that is evoked. Experiment 1 found strong effects of experimentally provided comparison context—for example, satisfaction with a given feedback time depended on the time's relative position within a context. Experiment 2 used a novel distribution‐elicitation methodology to determine the prior beliefs of individual students about what happens in universities other than their own. It found that these beliefs vary widely and that students' satisfaction was predicted by how they believed their experience ranked within the distribution of others' experiences. A third study found that relative judgement principles also predicted students' intention to complain. An extended model was developed to show that purely rank‐based principles of judgement can account for findings previously attributed to range effects. It was concluded that satisfaction ratings and quality of provision are different quantities, particularly when the implicit context of comparison includes beliefs about provision at other universities. Quality and satisfaction should be assessed separately, with objective measures (such as actual times to feedback), rather than subjective ratings (such as satisfaction with feedback promptness), being used to measure quality wherever practicable. © 2014 The Authors.

Cultural adaptation of preschool PATHS (Promoting Alternative Thinking Strategies) curriculum for Pakistani children

Cultural adaptation of evidence‐based programmes has gained importance primarily owing to its perceived impact on the established effectiveness of a programme. To date, many researchers have proposed different frameworks for systematic adaptation process. This article presents the cultural adaptation of preschool Promoting Alternative Thinking Strategies (PATHS) curriculum for Pakistani children using the heuristic framework of adaptation (Barrera & Castro, 2006). The study was completed in four steps: information gathering, preliminary adaptation design, preliminary adaptation test and adaptation refinement. Feedbacks on programme content suggested universality of the core programme components. Suggested changes were mostly surface structure: language, presentation of materials, conceptual equivalence of concepts, training needs of implementation staff and frequency of programme delivery. In‐depth analysis was done to acquire cultural equivalence. Pilot testing of the outcome measures showed strong internal consistency. The results were further discussed with reference to similar work undertaken in other cultures.     

患者的诊治期望值与医患矛盾的关系研究

从患者视角来探索医患矛盾发生的原因,寻找一种有效的医患沟通方法。研究认为医患矛盾的核心问题是患者对诊治期望值的不满意,通过构建以患者诊治期望值为主体的医患沟通方法,发现医生和患者之间对诊治期望值存在明显差异。医生通过对医患之间存在的差异性诊治期望值进行充分沟通,形成医患诊治期望值差异下的共识,建立互信合作的关系,最终实现医患互惠共赢。以患者诊治期望值为主体的医患沟通方法,为避免医患矛盾发生,促进和谐医患关系提供一种新的思路。

     

适宜技术与诊疗最优化的可行性研究

在案例分析的基础上,作出了医生是临床诊疗中适宜技术的主要选择者的判断;论证了运用适宜技术实现诊疗最优化的可行性;认为适宜技术难以选择和实施的主要原因是利益关系、责任心不强和管理措施不到位;提出了必须着力培育适合于适宜技术生长的土壤的对策,即:实行政策引导与资金支持、进一步加大监管力度、营造良好的氛围、高度重视并加强医生道德素质的培养。

医生健康素养认知调查及内涵探析

调查医生对健康素养概念及内涵、健康教育方式、存在问题等方面的认知情况。调查显示,一半以上的医生对健康素养了解程度一般,96.3%的医生认为病人的健康素养一般或差,96.7%的医生认为其有责任对病人进行健康教育,同时86.2%的医生认为医生健康素养与病人有区别。基于调查,提出医生健康素养应该具有双重属性,第一重属性为医生作为个体应该具备维持和促进自身健康的知识和能力;第二重属性为作为医生应该具备的本科室常见病相关健康教育知识、运用健康知识,针对病人健康问题进行有效沟通,提高病人健康素养水平的能力。

     

公立医院“医疗联合体”改革探析

公立医院“医疗联合体”改革模式为解决“看病难”问题提供了新思路, 其目的是促使优质医疗资源通过医疗联合体纵向下沉, 从而达到医疗资源最大化利用和居民就诊的合理分流。为了推进我国“医疗联合体”改革模式的发展, 首先分析了医疗联合体的作用和面临的障碍, 然后介绍我国上海、北京、湖北、重庆的“医疗联合体”改革实践模式, 在此基础上对我国“医疗联合体”改革发展提出相关建议, 期望对我国这种改革模式的实施推进提供一定的参考价值。
