图书馆情报学界的研究方法:实践与发展

本研究对2001年至2010年间发表于国际图书馆情报学三大主要期刊的共1162篇学术论文进行了定量和定性分析,结果表明,图书馆情报学界的学者所使用的研究方法在数量和种类上都超越以往。其中,内容分析法、实验法和理论研讨法取代了过去占主导地位的问卷调查法和历史研究法,成为本领域研究方法的首要选择。就研究方法而言,图书馆情报学科研论文呈现出两种趋势,一是同一项研究所采用的研究方法的多元化,二是对定性研究途径更加注重。但限于本研究所收集的数据量和时间跨度,上述两种趋势尚不足以成为定论。为了方便图书馆情报学学者在今后的研究中更好地了解和选择合适的研究方法,本文从适用性角度对研究方法进行了类分和讨论。回顾过去,图书馆情报学界已在研究方法的选择和使用方面取得了进步;展望未来,若在研究实践和方法培训方面作出恰当的努力,我们的研究将更上一层楼。表10。参考文献24。

中国市场秩序完善的内在机理与基本思路

无论是对"市场化问题"不断深入的定量、定性研究,还是对现实经济难题的溯源寻踪,无不彰显一个事实:中国以社会主义市场机制为体制目标的改革进程,已进入以质量建设为主,即以强化市场竞争秩序为主的新阶段。从学术上来看,完善中国社会主义市场经济体制仍需要进一步探索经济市场化的内在机理、逻辑理路。在借鉴诸多中外学者有关经济市场化、经济秩序理论研究成果的基础上,可以看出经济市场化(经济秩序的调整过程)本质上是三种秩序(经济秩序、法律秩序与社会秩序)相互依赖、整体互动、协同演进的过程。在这一秩序演进观的指导下,中国经济市场化具有"非均衡推进"特征:从外在上来看,中国的市场化进程带有明显梯度、层次推进特征;从深层上来看,则体现在法律秩序、经济秩序、社会秩序演进的差异程度上。随着改革的不断深化,经济体系中深层矛盾的出现,世界经济竞争加剧。

A good death from the perspective of healthcare providers from the internal medicine department in Shanghai:A qualitative study

Objective:This study aimed to explore the understanding of healthcare providers working in the internal medicine department in Shanghai regarding a good death.Methods:The data of the study was collected using face-to-face semi-structured interviews.Through purposive sampling,16 physicians and 13 nurses who had experiences of caring for adult patients with life-threatening illnesses at the end-of-life stage in Shanghai were interviewed.The interviews were analyzed using qualitative content analysis.Results:Six characteristics of a good death emerged:no suffering,companionship and care,no worries or concerns,dying with dignity,involvement and acceptance,and less impact on the family.Eighteen categories were identified:dying without experiencing suffering;being relieved of symptoms and suffering;being relieved of psychological suffering;avoiding the use of futile treatment and resuscita-tion;being cared for and accompanied by family;receiving good health care;having a meaningful life without regrets;making good arrangements for family issues;having a chance to say goodbye;having a quality life before death;dying in a decent environment;the personal will to be respected;maintaining the integrity of the body;death of the patient being accepted by the family and healthcare providers;the death occurred despite the best efforts to care for the patient;limited financial and care burden;shortly affected quality of life of the patient;and improved family cohesion.Conclusion:Family members’early involvement in caring for patients at the end-of-life stage helps achieve a good death.For patients with a terminal illness,avoiding unnecessary medical treatment and resuscitation could be the first step in achieving better patient death and promoting the development of advanced care planning in the mainland of China.

A qualitative study of childbirth fear and preparation among primigravid women:The blind spot of antenatal care in Lilongwe,Malawi

Objectives:This study aimed to explore childbirth fear and childbirth preparation among primigravid women in the late pregnancy from 36 to 40 weeks gestation.Methods:We purposively recruited 18 primigravid women into in-depth interviews,21 birth companions,and 13 health workers into focus group discussions.Participants were recruited from two community hospitals'maternity waiting homes in Lilongwe,Malawi.Semi-structured interview guides were used to collect data that were analyzed using content analysis.NVivo11 computer software was used to organize the data.Results:The four categories developed were:"ambivalent pregnancy feelings","dependence on traditional childbirth counseling","inadequate prenatal childbirth instruction"and"inconsistent roles of a birth companion".The findings suggest that primigravid women who were mainly exposed to traditional childbirth mentoring rather than professional care providers,experienced childbirth fear,and lacked proper psychosocial childbirth preparation.Conclusions:Childbirth fear among primigravid women emanate from personal;family;ineffective traditional counseling;and inadequate antenatal childbirth instruction.Birth companions may increase childbirth stress.However,our findings highlight birth companions as readily available psychosocial support resources among primigravid women.We recommend that professional childbirth instruction during antenatal care should be strengthened to surpass traditional childbirth counseling.Appropriateness and effectiveness of birth companions need to be carefully assessed.

Wheel-shaped icosanuclear Cu-containing polyoxometalate catalyst: Mechanistic and stability studies on light-driven hydrogen generation

In this paper,we report the synthesis and characterization of a wheel-shaped icosanuclear Cu-containing polyoxometalate(POM),K_(12)Li_(13)[Cu_(2)0Cl(OH)_(24)(H_(2)O)_(12)(P_(8)W_(48)O_(184))]·22H_(2)O(K_(12)Li_(13)-Cu_(2)0P_(8)W_(48)).The resulting cation-exchanged tetrabutylammonium salt of the polyoxoanion Cu_(2)0P_(8)W_(48)(TBA-Cu_(2)0P_(8)W_(48))exhibits high efficiency for visible-light-driven H_(2) production in the presence of an[Ir(ppy)2(dtbbpy)][PF_(6)]photosensitizer and a triethanolamine electron donor.Under optimal conditions,the turnover number for H_(2) production reaches~2892 after 5 h of photocatalysis and thereafter continuously increases to~13400 in a long-term 120 h reaction,representing the best performance among all reported transition-metal-substituted POM catalysts.Mechanistic studies confirm the existence of reductive and oxidative quenching processes,of which the reductive quenching pathway is dominant.Various stability tests demonstrate that the TBA-Cu_(2)0P_(8)W_(48) catalyst slowly dissociates Cu ions under turnover conditions;however,both the starting TBA-Cu_(2)0P_(8)W_(48) and its molecular decomposition products are dominant active species for efficient and long-term H_(2) production.

Effects of ration level and feeding frequency on digestibility in juvenile soft-shelled turtle, Pelodiscus sinensis

The effects of ration level and feeding frequency on digestibility in juvenile soft-shelled turtle, Pelodiscus sinensis, were investigated. Four ration levels 1.5%, 2.5%, 4.0% and satiation （6.0% BW/d） were used. Apparent digestibility （AD） of dry matter （DMAD）, protein （PAD） and protein real digestibility （PRD） were significantly affected by ration level, but not by feeding frequency when the ration level was similar. However, the feeding frequency affected the AD, DMAD, PAD and PRD significantly when the turtles were fed to satiation. The relationship between fecal protein content （Y） and protein intake （At） can be expressed as a quadric equation： Y=-0.1742＋0.1476X-0.0003X^2 （r^2=0.876, n=27, F=93.92, P〈0.01）.
