Momentary maximizing in concurrent schedules with a minimum interchangeover interval

Eight pigeons were trained on concurrent variable-interval variable-interval schedules with a minimum interchangeover time programmed as a consequence of changeovers. In Experiment 1 the reinforcement schedules remained constant while the minimum interchangeover time varied from 0 to 200 s. Relative response rates and relative time deviated from relative reinforcement rates toward indifference with long minimum interchangeover times. In Experiment 2 different reinforcement ratios were scheduled in successive experimental conditions with the minimum interchangeover time constant at 0, 2, 10, or 120 s. The exponent of the generalized matching equation was close to 1.0 when the minimum interchangeover time was 0 s (the typical procedure for concurrent schedules without a changeover delay) and decreased as that duration was increased. The data support the momentary maximizing theory and contradict molar maximizing theories and the melioration theory.     

Evaluating children's mental health service systems: An analysis of critical behaviors and events

A lack of studies which evaluate system change by tracking client outcomes is noted in the children's mental health area. This deficit may be a result of the inability of researchers to define outcomes and to draw conclusions about which measures reflect the efficacy of services and service delivery systems. This paper reviews five social validation surveys which examined children's mental health outcome measures. Based on the results of the five surveys, a model of critical behaviors and events is presented. This model will assist evaluators and researchers in understanding which critical events and behaviors should be measured to assess the impact of community-based mental health services for children.     

预防患者术中知哓的早期心理干预——颅内动脉瘤介入栓塞术患者中的研究

探讨早期心理干预在预防颅内动脉瘤栓塞术患者术中知晓的效果。将100例患者按入院先后顺序随机分为观察组和对照组,各50例,均实行整体护理,对照组给予常规的术前、术后护理,观察组在常规护理的基础上给予一系列针对术中知晓的心理护理干预措施。观察组干预前后焦虑程度明显减轻（P〈0．01）,对护理质量满意度均优于对照组（P〈0．05）,差异有统计学意义。针对不同患者心理状态进行系统的早期心理干预可减轻脑血管介入患者术前焦虑情绪,从而积极有效地预防颅内动脉瘤栓塞术患者术中知晓的发生,提高护理质量满意度。     

新生儿重症监护病房患儿家属心理状况分析

探讨新生儿重症监护病房（NICU）住院患儿家属的心理状况及影响因素。采用焦虑自评量表（SAS）及自行设计的调查问卷对190名NICU住院患儿家属进行调查。结果显示患儿家属表现出不同程度的焦虑,与全国常模（29．78±0．46）相比,其焦虑情绪标准分49．54±1．07,高于常模组（P〈O．05）。影响因素主要包括文化水平、家庭人均收入及患儿病情严重程度等。患儿父母关注的主要问题包括：病情严重程度、预后、医护人员解释病情满意度及病房探视制度。笔者认为医护人员应加强与患儿家属的有效沟通,满足其心理需求,提高医疗护理质量,促进医患关系和谐。     

Center-Based Care for Young Children: Examining Predictors of Quality

The authors collected information from caregivers, trained observers, and parents to investigate quality elements in child-care programs designed for young children in center-based settings. Participants were 75 parents of children aged 15 to 36 months and their caregivers from 13 child-care centers in a southeastern state. Observers collected indicators of program quality and process and structural quality indicators, including adult-child ratio, group size, use of planned activities, use of child-designated space, housekeeping activities, and caregiver-child interactions. Participants responded to questions regarding their child-rearing beliefs, social support networks, perceived stress levels, and demographic characteristics. The best predictors of higher quality care and sensitive caregiver-child interaction in centers were specialized caregiver training, higher adult-child ratios, use of planned activities, and less perceived stress by caregivers. Implications of these findings are discussed.     

构建高质量的外科医学教育体系

医学教育是贯穿医疗职业生涯全过程的行为,是伴随医学进步和发展的重要工程.医学教育的质量直接影响医疗的质量和医学人才的素质,尤其是外科学领域,是以有创性的手段、方法治疗疾病.医生的职业素养、医疗水平均取决于医学教育的结果.医疗质量不能简单地用医生的学历衡量,学历教育是载体,其中应充实培养能力的教育项目、内容,以适应未来就职、就业的社会需求.医疗质量、医疗水平对医院而言是生命线,是生产力.同时,医生的教育及教育的质量是医疗质量的基础与保障.随着医学的飞速发展,医疗技术的日新月异,医学模式的改变,构建新的医疗环境下的医学教育体系,显得更为重要.     

临床共情与护理技术结合：人性化的护理

临床共情是一种能体验患者内心世界的能力,通过患者的言语和非言语表达,觉察和认识患者情感和情绪需求,并对其做出恰当的回应.临床共情具有科学的理论和实践基础,具有缓解患者心理上的痛苦,改善护患关系,促进患者康复等作用.在当今复杂的医疗环境下,务必要重视共情培养,适时运用临床共情.然而,我们强调临床共情的重要作用,并不能忽视护理技术的根本作用,根除躯体上的病变仍有赖于护理技术的有效性.在临床护理实践中,坚持共情与护理技术的有机结合,推进人性化的护理构建.     

Soins pénalement ordonnés et positionnements professionnels : des pratiques au carrefour de la Santé et de la Justice

At the crossroad of Health and Justice, penally ordered care underlies professional practices, the articulation of which can turn out to be delicate. Here we tackle the relevance and practical application of these measures. For that purpose, semi-directive interviews and field observations have been conducted with probation agents, judges (who follow up the way sentences are executed) and psychologists. The professionals’ comments and experiences show the complexity of these measures, which intend to make “care” into a recidivism prevention tool. Misconceptions appear about theory, practices and interprofessional relationships. The idea of “care” as a sole medical term appears to be ineffective and calls for the creation of new practices.     

影响ICU护士落实“知情同意原则”原因及对策

重症监护（intensive care unit,ICU）医生越来越重视在诊疗活动过程中的知情同意权,各种重要诊疗活动都与患者和家属沟通,并取得口头或文字上的同意,但部分护理人员对知情同意原则不重视,在环节中落实不力,从而易引发护患纠纷。而保证患者获得知情同意权是护理人员必须落实的义务,护士的告知是维护患者知情同意权和...     

"以病人为中心"医疗服务模式的理念与发展

纵观20世纪医疗服务的发展历程,医疗服务的发展经历了“以疾病为中心”的传统医疗服务模式到“以病人为中心”的新的医疗服务模式的转变;目前,以“以病人为中心”的医疗服务模式已经成为我国现代医院改革与发展的主题。因此,在阐述医疗服务模式变革与发展的基础上,系统论述了“以病人为中心”的医疗服务模式的内涵与特点,新的理念、新的认识,也带来了新的希望,新的医疗服务模式将不断地改善与提高人们的健康状况与生活质量。
