品牌延伸:资产价值转移与理论模型创建

本文通过对品牌延伸(Brand Extension)的研究综述和实证研究,提出决定品牌延伸的三大因子,并在此基础上构成品牌资产价值(Brand Asset Value),进而研究其在品牌延伸过程中的价值转移,从而构成了评估品牌延伸成败的标准,最终将各种因子和评估标准进行整合,提出了品牌延伸的理论模型。     

A Tiered Framework for Risk‐Relevant Characterization and Ranking of Chemical Exposures: Applications to the National Children's Study (NCS)

A challenge for large‐scale environmental health investigations such as the National Children's Study (NCS), is characterizing exposures to multiple, co‐occurring chemical agents with varying spatiotemporal concentrations and consequences modulated by biochemical, physiological, behavioral, socioeconomic, and environmental factors. Such investigations can benefit from systematic retrieval, analysis, and integration of diverse extant information on both contaminant patterns and exposure‐relevant factors. This requires development, evaluation, and deployment of informatics methods that support flexible access and analysis of multiattribute data across multiple spatiotemporal scales. A new “Tiered Exposure Ranking” (TiER) framework, developed to support various aspects of risk‐relevant exposure characterization, is described here, with examples demonstrating its application to the NCS. TiER utilizes advances in informatics computational methods, extant database content and availability, and integrative environmental/exposure/biological modeling to support both “discovery‐driven” and “hypothesis‐driven” analyses. “Tier 1” applications focus on “exposomic” pattern recognition for extracting information from multidimensional data sets, whereas second and higher tier applications utilize mechanistic models to develop risk‐relevant exposure metrics for populations and individuals. In this article, “tier 1” applications of TiER explore identification of potentially causative associations among risk factors, for prioritizing further studies, by considering publicly available demographic/socioeconomic, behavioral, and environmental data in relation to two health endpoints (preterm birth and low birth weight). A “tier 2” application develops estimates of pollutant mixture inhalation exposure indices for NCS counties, formulated to support risk characterization for these endpoints. Applications of TiER demonstrate the feasibility of developing risk‐relevant exposure characterizations for pollutants using extant environmental and demographic/socioeconomic data.     

Training needs of extension agents’ regarding organic agriculture in Saudi Arabia

The purpose of this study was to investigate the needs of extension agents for training on organic agriculture (OA) in the Riyadh Region. Fifty-five percent (n = 69) of extension agents were selected to collect data through an electronic survey. Results indicated that extension agents in the Riyadh Region cited on job training as a main source for acquiring knowledge in OA. Agents expressed interest in receiving training in OA in general, OA marketing, and transitioning to OA. The most useful resources were field days at organic farms, OA training sessions at colleges, and attending OA trial plots. There were no differences in the level of interest in training; however, there were significant differences between individuals in terms of their experience in OA, job responsibility for providing information related to OA, and area of specialization in their job. This study recommends developing professional training programs based on the current knowledge of extension agents.     

追诉时效延长制度探讨

新旧刑法均有关于追诉时效的规定 ,但在追诉时效延长方面规定却有不同。本文认为追诉时效延长制度应当有三种情况 ;同时对这一制度的可能产生歧义的地方进行了理论上的辨析。     

母──婴依恋关系的形成及其作用

母──婴依恋关系的形成及其作用刘芳随着人们对情绪在个体心理生活中重要作用的认识，母─—婴依恋作为个体社会性情绪发展的基础也成为儿童发展研究的重要内容之一。然而，在我国这方面的研究很少，尤其在提倡计划生育、优生优育的今天，尽快弥补这一课题具有重要的理论...     

Resolving conflicting demands on evaluation: A test demonstration of videotex for farmers

Evaluating an innovation for federal, state, and local policymakers and program managers alike entails conflicting demands on the evaluation study. Policymakers at federal, state, and local levels are best assisted by impact evaluations, whereas state and local program managers are best assisted by process evaluations. In-house evaluators often have an advantage in conducting process evaluations; external evaluators generally have an advantage in conducting impact evaluations. A cost-effective approach may be to combine in-house process evaluation and external impact evaluation. This dual approach was found to reduce conflicting demands on the evaluation of an experimental videotex system for agricultural producers.     

数字时代中广告插画艺术的变革

人类进入数字时代后,先进的计算机技术不仅克服了文字数字化的难题,而且征服了比文字更复杂的声音、图像世界。主流与非主流插画开始应用到生活的各个方面,涉及到装修、时装、数码产品、互动媒体、电影、广告等等领域。面对正日益缩小的传统插画传播媒介间的差距,传统的传播者与受众之间的相互关系正面临巨大的变革。     

社会教育概念探微

随着现代社会的发展和终身教育理念的提出,社会教育的地位和作用越来越突出,要充分挖掘社会教育的功能,最大限度地发挥社会教育的作用,有必要厘清社会教育的概念,明确其边界.国内外学界对于社会教育概念的研究,主要有"补充教育论"、"教育影响论"和"系统教育论",也有一些学者对马克思社会教育概念进行了探讨.社会教育不同于社会照顾、青年帮助、公民教育,是社会为促进人的全面发展和社会进步,而采用的有目的、有计划、有组织的种种教育实践活动.     

农业推广硕士与现代农业发展关系研究

农业推广硕士专业学位于1999年由国务院学位办批准设置,2000年首次招生以来,发展迅速,已成为农科专业学位中发展得最快的专业学位类型。文章试图从现代农业角度剖析农业推广硕士专业学位设置及快速发展的动因,为农科专业学位的可持续发展提供基础信息。     

存现句在篇章中的节缩、扩展和变异

以往对存现句的研究多是从典型的结构入手做静态的分析,本文把其放在篇章之中做动态的探讨。存现句的变化是丰富多彩的:有自身结构的节缩,简单明了,突出存在主体;有外在成分的介入,构成更大的语句,表达更加丰富的意义;还有的更换了A、B、C三段固有的构成成分,打破了原有的格局,变不可能存在、出现、消失的人或物为可能,新颖别致,不落俗套,扩展了存现句的使用功能。
