我国农村人口出生性别比偏高的动力机制研究

B超的滥用、强烈的男孩偏好以及对非法流产行为监控的失效共同构成我国出生性别比偏高的充要条件,三者中任一条件不满足都不可能出现出生性别比偏高。尽管B超发明和滥用前出生性别比并没有异常,但也不能说出生性别比偏高与受教育水平、传统文化等因素无关。事实上,这些因素通过影响男孩偏好和B超的可获得性而影响出生性别比。由此出发,促进出生性别比回复正常,短期内应标本兼治,以治标为主———坚决禁止B超的滥用,关键是加强立法和管理;长期内则必须治本———消除男孩偏好,关键是加速农村城市化。

The ecosystem blueprint: How firms shape the design of an ecosystem according to the surrounding conditions

Ecosystems are formed by organisations that jointly create a value proposition that a single firm could not create in isolation. To deliver this value proposition, the partners need a focal firm, the orchestrator, to be align them towards the joint value proposition. Thus, how orchestrators design the alignment structure of an ecosystem is at the very heart of the ecosystem concept – yet it has not been sufficiently addressed by extant research. This is all the more true for the question of how the design of an ecosystem is shaped depending on surrounding conditions. This paper applies a qualitative study with ten cases and, based on the attention-based view of the firm, contributes to research on ecosystems in several ways. First, it explains which ecosystem designs are beneficial under which conditions. Second, it elucidates the structure and activities within ecosystems and shows that start-ups can be just as good ecosystem orchestrators as incumbents. Third, it explains the circumstances under which single vs. multi orchestrator ecosystems occur. Fourth, it presents the conditions when incumbents or start-ups make better orchestrators. Finally, it is among the first studies to apply the attention-based view to business ecosystems, and shows that doing so yields intriguing insights into this emerging field of research.     

The validity of indices for rural health manpower needs assessment

Population-to-practitioner ratios have long been the primary index in the designation of health manpower shortage areas. This paper documents that application of the widely used population-to-dentist index results in understatement of the need for dental health manpower in rural areas. Through the analysis of utilization data collected from a statewide health screening program in Colorado, the practice of sole reliance on the population-to-dentist indices as an indicator of need was tested. Another measure, the area-(square miles) to-dentist ratio was formulated, examined, and found to be a more useful referent of the need for additional health manpower in rural areas. Utilization of dental services in sparsely settled rural counties of Colorado was unrelated to population-to-dentist ratios. A strong, statistically significant association of utilization with land area-to-dentist ratios was found. The findings of this analysis suggest a need for reevaluation of needs assessment methodologies used in the designation of health manpower shortage areas. Indices more sensitive to consumer circumstance than to the number of health care providers available must be considered.     

SO42-/TiO2催化合成乙酸乙酯的实验设计

SO4^2-／TiO2固体超强酸薄膜化催化剂能完全代替浓硫酸作催化剂,用乙酸、乙醇来合成乙酸乙酯。在膜催化器上,考察了薄膜化催化剂对乙醇和乙酸合成乙酸乙酯的催化性能。结果表明,薄膜化催化剂显著提高了催化活性;当n（乙醇）：n（乙酸）=1．5：1,原料流量3．0mL／h,在反应温度为110℃时,乙酸乙酯产率可达94．8％,且薄膜催化剂的处理很方便,催化剂再生后可重复使用,不污染环境。     

黄河流域数字经济与新型城镇化耦合协调及驱动机制

黄河流域生态保护和高质量发展重大国家战略背景下,推动数字经济和新型城镇化深度融合是保障黄河长治久安的必然要求。通过阐释数字经济与新型城镇化的耦合协调机制,构建数字经济测度指标体系、新型城镇化评价指标体系,运用熵值法测度评价2012-2021年黄河流域数字经济、新型城镇化综合发展水平,利用耦合协调模型、空间自相关模型、地理探测器等方法,从时序演变和空间特征两方面分析黄河流域数字经济与新型城镇化的耦合协调发展水平及耦合协调度驱动机制。研究发现:(1)黄河流域数字经济和新型城镇化综合发展指数呈上升趋势;(2)从时序演变看,黄河流域数字经济与新型城镇化的耦合度、协调度及耦合协调度均有所提升,其中耦合协调度呈轻度失调 濒临失调 勉强协调演变,由衰退失调型转向过渡磨合型,整体未达到协调发展;从空间特征看,耦合协调度呈“南高北低”的空间格局;(3)不同驱动因子对黄河流域数字经济与新型城镇化耦合协调度的影响具有显著时间异质性和空间异质性。据此,提出推动黄河流域数字经济与新型城镇化耦合协调发展的对策建议。     

家庭功能与小班幼儿亲社会行为的关系：安全型依恋的中介作用和性别的调节作用

基于McMaster家庭功能模式理论和依恋理论,选取392名小班幼儿为被试,通过问卷调查探讨家庭功能与小班幼儿亲社会行为的关系,并检验安全型依恋的中介效应和性别的调节效应。结果显示,家庭功能、亲社会行为、安全型依恋两两之间均呈现显著的正相关。安全型依恋在家庭功能与小班幼儿亲社会行为的关系中起着部分中介作用。性别显著调节家庭功能与亲社会行为之间的关系。具体而言,家庭功能显著正向影响女性幼儿的亲社会行为,但对男性幼儿亲社会行为的影响并不显著。
