不同经营形式下的私有林经营规模效率研究——以福建为例

研究林业经营效率是林业经营管理与林业政策的重要议题,对不同经营形式下的私有林经营规模效率进行研究具有重要的现实意义。本文以林农的经营形式为切入点,通过对福建省三大林区的调查,运用DEA方法测算与分析了自留山经营、家庭承包经营、股份合作经营等三种形式的私有林规模经营效率,得出了总体规模效率有待提高、股份合作经营规模效率相对较高、生产要素配置不太合理等结论,最后对提升私有林林地经营规模效率提出了因地制宜,选择多形式的林地经营形式;完善林地流转制度,提高林业整体规模效率;优化资源配置,提高林业生产效率等建议。     

对我国土地行政管理体制的思考

目前中国正处在经济高速发展、城市化和工业化突飞猛进的时期，非农用地的需求不可避免将进一步增长。不仅国家粮食安全、生态安全、保证建设用地需求与耕地有关，其他一系列社会问题也在耕地转移的过程中反映出来。面对诸如此类的问题．土地行政管理如不能统筹各种关系，就会陷入顾此失彼的境地，一切症结也正在于此。这里主要谈一下“统筹城乡协调发展”和“统筹一要吃饭，二要建设”两个关键问题。     

基于品类管理的制造商与零售商组织合作研究

美国在上世纪90年代提出的品类管理概念，在全球得到了普遍的应用。这促进了传统制造商与零售商之间的买卖关系逐渐上升到战略性合作伙伴关系。本文根据品类管理的流程，探讨制造商与零售商在组织合作方面容易遇到的问题以及解决方案。     

计划生育工作新机制与人口管理科学的发展

计划生育工作新机制反映了人口管理科学的发展。回顾人口管理学的发展历史,研究我国计划生育工作从旧机制转向新机制,与人口管理科学从传统走向现代的密切联系,积极推动人口管理科学的进一步发展。     

Improvisation – An emergence theory perspective

The paper addresses the occurrence of improvisation and intuition within dynamic business environments from an emergence theory perspective. As argued, the dynamics of the so-called red queen principle forces competition towards the verge of the manageable, making improvised and intuitive action and decision-making not a shortcoming but a necessity in a successful business context. Particularly, the paper discusses how we may interpret the highly rationalistic acts and outcomes of planning and plans in such chaotic and uncertain contexts. We draw upon a longitudinal study of large industrial project deliveries incorporating more than 25 such deliveries.     

我国灾后废墟管理的进程、问题与趋势初探

废墟管理和垃圾废物处理,是灾后恢复重建以及环境保护工作的难点和重要内容。近年来,我国自然灾害频繁,废墟量不断增多,废墟垃圾若不综合利用、处理,不仅影响灾后恢复重建,而且还会加重生态灾难。而我国在废墟管理方面还相对落后,在废墟处理、管理等环节存在突出问题和技术难题。借鉴日本废墟管理有益经验,废墟管理呈现向专业化、市场化、智能化和法制化方向发展的趋势。     

Assembling the dance: reggae sound system practices in the United Kingdom and France

Reggae sound systems are assemblages of speakers, record decks, and amplifiers that permit sound to be reproduced at very powerful levels. Sound systems crews, alongside an extended affinity group, build their own systems and organize and engineer the space of the dance. Interviews with crews from the United Kingdom and France reveal differences in how they each draw from the history of Jamaican musical experimentation when making spaces to collectively immerse the crew and crowd in sound. Yet in both cases, their approach to sound design communicates a commitment to inclusivity, maintaining an emphasis on the “vibe,” which progressively alters participants’ somatic experience and perceptions. In contrast to “dancehall” in Jamaica, such sound systems disrupt understandings of a “standard” setup that reinforces hierarchical relationships between performers and audience. Crews also downplay the visual aspects of the “dance” and dancing and are consciously non-consumerist. Thus, different crews’ histories and associations alter how they enact, feel, and understand similar conventions.     

论宋太祖制御边将的两手策略

北宋建立之初,面对巩固新政权和继续进行统一战争的艰巨任务,宋太祖在内地实行＂强干弱枝＂的同时,于边防地区部署重兵。为更好地制御边将,他采取了不同于内地的两手策略。经济上宽纵与政治上严控相辅相成,是宋太祖制御边将策略的主要特点。这些策略做法对当时及太祖以后的宋朝历史产生了重要而深远的影响。     

应用GIS 技术辅助油藏管理

油气藏开发涉及油气藏的三维空间分布和内部状态变化的复杂问题,信息系统是支持油藏管理的基本手段。传统油气藏开发管理信息系统基于表格形式表现对象属性,无法反映描述对象的空间联系和系统的空间分布模式。地理信息系统( GIS) 能够有效描述二维空间问题,将GIS 技术引入油气藏开发管理信息系统将极大地扩展管理信息系统的描述能力和表现形式,但是对于油气藏开发这类特殊的三维问题还缺少描述和分析能力。通过分析传统的油藏管理信息系统所面临的问题,提出了油气藏开发管理GIS 系统的体系结构、目标设计和功能设计,讨论油气藏开发管理GIS 系统的技术路线、信息组织方式、表示方式以及开发模式,指出需要研究更完善的三维空间描述方法和表现手法,结合油藏描述技术及其成果,在地质建模的基础上开展空间分析,将会使油气田开发中的GIS 技术更加完善。     

Differences in health-related quality of life among persons living with HIV/AIDS

We sought to identify differences in health-related quality of life (HRQoL) among a sample of HIV positive individuals receiving case management services in northern Florida. Our study consisted of 97 individuals receiving HIV case management that included 56 males (57.7%) and 81 African Americans (83.5%) who were 47.05 years old (SD = 9.33). HRQoL was measured using the HIV/AIDS Targeted-Quality of Life scale (HAT-QOL). Results show significant group differences in HRQoL by race, income, tobacco use, alcohol use, drug use, and CD4 cell count, despite only 43% of this sample being able to recall their most recent CD4 count. Translating these findings to inform practice, HIV care providers need to provide continuing education to patients about their disease status, knowledge, and treatment as it relates to self-care. Also, HIV care providers should be especially cognizant of the impact that tobacco, alcohol, and illicit drug use has on HRQoL for persons living with HIV/AIDS (PLHA) by working to assess social support, identify readiness for change, and make appropriate referrals for treatment.
