心理干预复合咪达唑仑对腔镜手术心理应激反应的影响

探讨心理干预复合咪达唑仑对腹腔镜全宫切除患者术前心理应激反应的影响。择期行腹腔镜全宫切除术患者90例,ASAI或Π级,随机等分为3组：对照组（C组）,不用术前用药;咪达唑仑组（M组）,术前30 min肌注咪达唑仑0.05 mg/kg;心理干预复合咪达唑仑组（PIM组）,按照心理干预方法进行术前访视,术前30 min肌注咪达唑仑0.05 mg/kg。术晨8时及入室后即刻测定3组患者的血清ACTH、Cor、AT-Π与IL-6水平,记录术前一日访视时及入室后即刻的MAP、HR和SpO2值,并行S-AI、AVAT评分。心理干预复合咪达唑仑能明显减轻腹腔镜全宫切除术患者术前的心理负担和焦虑程度,不失为一种调控手术患者术前急性不良心理应激反应的简便易行而又切实有效的方法。     

Structural effects of cognitive and affective reponses to web advertisements,website and brand attitudes,and purchase intentions: The case of casual-dining restaurants

This study investigates the structural relationships among responses to website advertisements, website attitudes, brand attitudes, and purchase intentions in the case of web advertisements for casual-dining restaurants. Responses toward advertising (Rad) factors were categorized as cognitive responses and affective responses. The SEM model in LISREL was used to examine the interrelationships among the proposed hypothesized constructs. Several empirical results were obtained. First, Rad had a positive effect on website attitudes. Second, website attitudes had a positive effect on brand attitudes. Third, brand attitudes had a positive effect on purchase intentions. Finally, some discussion and implications of the study are provided.

有限理性条件下民营企业资源配置欠优的机理研究

以浙江民营企业为例,借鉴有限理性博弃的相关理论,本文建立了有限理性条件下我国民营企业资源配置协调博弃的快速学习模型和复制动态进化模型;详细分析了存在理性局限的情况下,民营企业资源配置策略结果偏离最优状态的机理,并指出改善这种欠优资源配置策略的可能途径.     

民间投资与产业转型——以浙江省为例

本文以浙江省为例,利用浙江改革开放后30多年的数据资料,对民间投资比重和三次产业的比重进行协整建模分析,分析结果表明,民间投资对浙江三次产业结构的变化起到重要的作用。民间投资比重上升是拉动浙江第三产业比重上升的原因,从而也说明了浙江第三产业的发展主要是依靠民间资本的投入;但对第二产业而言,民间投资对其的作用是反向的,这说明浙江第二产业的发展主要不是依靠民间资本的投入,而是依靠政府的投资。     

The relationship between risk experience and risk response: a study of farmers and climate change

Within the existing literature, the role of experience of risk on attitudinal and behavioural risk response has been relatively neglected. Recent research that draws on the psychological distance of climate change as a concept notes the importance of local, significant experience as a driver for encouraging appropriate response. The experience of flooding was used as the stimulus in this paper, and emphasis placed on whether direct and/or indirect experience of flood risk is associated with different responses to climate change risk. In order to explore the relationship between climate change risk experience and response in the form of on-farm mitigation and adaptation, this paper draws on a case study of farmers in England, many of whom have experienced flooding. Results from a quantitative survey undertaken with 200 farmers in Gloucestershire, England are discussed. Statistical analysis found experience of flooding to be significantly associated with a heightened concern for climate change. Although also finding an association between experience and behavioural response, the sample were most likely to be taking adaptive behaviour as part of normal practice, with factors such as lack of overall concern for climate change risk and absence of information and advice likely to be the main barriers to action. Risk communication needs to further emphasise the connection between climate change and extreme weather events to allow for farmers to perceive climate change as a relevant and locally salient phenomenon, and subsequent tailored information and advice should be offered to clearly illustrate the best means of on-farm response. Where possible, emphasis must be placed on actions that also enable adaptation to other, more immediate risks which farmers in this study more readily exhibited concern for, such as market volatility.     

新兴产业对经济发展的时变性影响——来自京津冀地区的经验分析

本文建立了带有随机波动率的时变参数向量自回归模型（SV-TVP-VAR），以京津冀地区为研究对象，分析了不同时期新兴产业发展对地区生产总值、财政收入以及就业的影响。研究结果发现：（1）新常态时期新兴产业的发展对京津冀经济状况的影响程度大于在全球经济危机时期和经济高速发展时期的影响程度，但在大部分时期新兴产业的发展都只会对京津冀的经济状况产生负向效应；（2）如果经济增长是首要经济目标，天津应该加强新兴产业的发展，如果就业是首要经济目标，河北应该加强新兴产业的发展。     

Aggregate supply response in Tanzanian agriculture

Tanzania is among the many African countries that have engaged in agricultural liberalization since the mid-1980s. in the hope that reforms that introduce price incentives and efficient marketing will encourage producers to respond. This paper assesses that claim by examining the supply response of agricultural output in Tanzania. Our estimates suggest that aggregate agricultural supply response is quite high so that the potential for agricultural sector response to liberalization of agricultural prices and marketing may be quite significant. The long-run elasticity of aggregate food crop output to relative prices was almost unity. Short-run supply responses were estimated at about 0.35 for aggregate food crops and for all (food and export) crops. Liberalization of agricultural markets, where it increases the effective prices paid to farmers, can be effective in promoting production, although complementary interventions, to improve infrastructure, marketing, access to inputs and credit, improved production technology etc, are probably necessary.     

Exploring the impact of R&D and climate change on agricultural productivity growth: the case of Western Australia*

This article empirically examines the impact of R&D and climate change on the Western Australian Agricultural sector using standard time series econometrics. Based on historical data for the period of 1977–2005, the empirical results show that both R&D and climate change matter for long‐run productivity growth. The long‐run elasticity of total factor productivity (TFP) with respect to R&D expenditure is 0.497, while that of climate change is 0.506. There is a unidirectional causality running from R&D expenditure to TFP growth in both the short run and long run. Further, the variance decomposition and impulse response function confirm that a significant portion of output and productivity growth beyond the sample period is explained by R&D expenditure. These results justify the increase in R&D investment in the deteriorating climatic condition in the agricultural sector to improve the long‐run prospects of productivity growth.
