药剂防除花卉栽培基质线虫的探讨

[目的]寻找出最有效、最经济、残留少、对花苗无损害的化学处理药剂及其最佳处理组合.[方法]将万强、阿维菌素、益舒宝、地宝4种杀线虫剂稀释为400倍、500倍、600倍浓度溶液喷洒处理花卉栽培介质,再加盖薄膜密封,分别于2天、4天后取样,并揭膜散气3天和14天,检查灭线虫效果,并观察是否对花苗造成损害.[结果]地宝处理2天无明显效果,其他处理都有效果;同一药物处理相同天数,浓度越高效果越好;同一药物同一浓度处理4天效果优于2天,同一浓度不同药物处理2天,其效果阿维菌素＞万强＞益舒宝＞地宝;处理4天,其效果阿维菌素＞益舒宝＞万强＞地宝.400倍稀释的阿维菌素处理4天效果最理想.药剂处理后放置3天的基质对所种植花苗产生了较严重损害,放置14天的对花苗损害较轻,但不及未经处理的基质所种花苗茁壮.[结论]地宝、万强不适合用于花卉栽培介质处理;阿维菌素500倍液和益舒宝400倍液4天均可达到预期效果.阿维菌素杀虫谱广,残留低,使用安全,益舒宝更经济,二者均可选作处理剂,阿维菌素效果最优.所有化学药剂在一定时间里都对花苗有损伤,7～14天后方可栽培植物.

春季育肥肉牛要点

春季到来，天气开始转暖，这是肉牛一年中生长最快的季节。为了保证肉牛有较快的生长速度，饲养者应做好以下儿方面的工作：（一）驱虫。很多养牛户常用阿维菌素、伊维菌素等药物对肉牛进行驱虫，但由于所买驱虫药物含量达不到规定标准，以致驱虫效果不理想.笔者向大家推荐吩苯达唑，在每吨饲料中添加0．5公斤吩苯达唑，按正常饲喂方法饲喂，对肉牛体内，体外的寄生虫均有良好的驱除效果。[第一段]

Quick decisions tend to reinforce self‐interest choices among MBA students: The direct and moderating effects of temporal constraint and situational factors in ethical decision making

Employees face increasingly time‐pressured operational environments. Using theory from Reynolds' ( 2006 ) neurocognitive model of ethical decision making, we explore how temporal constraint, consequence framing, and organizational norms affect self‐interested decision making in business. Conducting three experimental manipulations with a sample of MBA students, we found the following: First, consistent with previous studies, high time pressure promotes self‐interested intentions. Second, unethical framing encourages self‐interested intentions, though this relationship is unaffected by the presence of time pressure. Third, unethical organizational norms encourage group‐interested intentions. Lastly, however, when these same norms are experienced under high time pressure, individuals display self‐interested intentions. Copyright © 2016 ASAC. Published by John Wiley & Sons, Ltd.     

Principles involving marketing policies: An empirical assessment

We examined nine marketing textbooks, published since 1927, to see if they contained useful marketing principles. Four doctoral students found 566 normative statements about pricing, product, place, or promotion in these texts. None of these statements were supported by empirical evidence. Four raters agreed on only twenty of these 566 statements as providing meaningful principles. Twenty marketing professors rated whether the twenty meaningful principles were correct, supported by empirical evidence, useful, or surprising. None met all the criteria. Nine were judged to be nearly as correct when their wording was reversed.The authors thank the many people who commented on early drafts, including Eileen Bridges, Fred Collopy, Douglas Dalrymple, Alan Dubinsky, Andrew Ehrenberg, Jonathan Freeman, Raymond Hubbard, William Perreault, William Ross, Steven Schnaars, and Gerald Zaltman.

Vinyl record: a cultural icon

In this paper, we use the case of the vinyl record to show that iconic objects become meaningful via a dual process. First, they offer immersive engagements which structure user interpretations through various material experiences of handling, use, and extension. Second, they always work via entanglements with related material ecologies such as turntables, speakers, mixers, and rituals of object care. Additionally, these engagements are complimented by a mediation process which emplaces the vinyl historically, culturally, spatially, and also politically, especially in the context of digitalization. This relational process means that both the material affordances and entanglements of vinyl allow us to feel, handle, experience, project, and share its iconicity. The materially mediated meanings of vinyl enabled it to retain currency in independent and collector’s markets and thus resist the planned obsolescence and eventually attain the status of celebrity commodity with totemic power in music communities. This performative aspect of vinyl markets also means that consumers read closely the signals and symbols regarding vinyl’s status, as its various user groups and champions try to interpret its future, protect, or challenge its current position. Vinyl’s future, and the larger expansion of pressing plants and innovative turntable production around it, largely depend on processes of cultural and status mobility. In the current phase of market expansion, vinyl’s status might be challenged by its own success. Neither a fashion cycle phenomenon, nor simple market conditions explain vinyl’s longevity. Rather, cultural contextualization of vinyl as thing and commodity is crucial for avoiding symbolic pollution and retaining sacred aura.     

Factors Associated with Opinion Seeking

Abstract

This study examines the relationship between opinion seeking and cultural values and individual characteristics in the context of electronic products by surveying cosmopolitan adults of 15 nationalities, namely, American, Australian, British, Dutch, Filipino, German, Hong Konger, Indian, Italian, Japanese, Malaysian, New Zealander, Singaporean, Swedish, and Thai. It finds (i) positive correlation between opinion seeking and power distance, category knowledge, category purchase intention, category innovativeness, opinion giving, market maven, brand loyalty, and susceptibility to interpersonal influence, (ii) negative correlation between opinion seeking and the masculinity and uncertainty avoidance cultural dimensions, category ownership, self-esteem, education, and age, and (iii) no correlation between opinion seeking and individualism, long-term orientation, and risk taking. It then discusses the managerial implications of the findings.

Who Invests in the Least Developed Countries?

Abstract

Africa is a giant market with a population of Europe and Japan combined, and highly diversified with respect to culture, natural resources, economic development, and political regimes. Yet, the continent is largely ignored with respect to research on the multinational activities of U.S. firms. In this paper, we provide the first evidence regarding the operating characteristics of U.S. firms that operate in Africa. We find that firms with operations in Africa are larger, more diversified, and more profitable than a matched control sample of multinational firms. This paper also shows that technology firms, manufacturing firms, and mining firms dominate the rest of companies operating in Africa. Certain geographical regions in Africa also seem to attract more companies than others, with Southern Africa being the most preferred region, while Central Africa is the least preferred. Finally, when a multinational firm invests in a specific country in Africa, it tends to do so in several business sectors.     

Utility of Ethical Frameworks in Determining Behavioral Intention: A Comparison of the U.S. and Russia

Using Reidenbach and Robin‘s ( Journal of Business Ethics 7, 871–879, 1988) multi-criteria ethics instrument, we carried out the first empirical test of Robertson and Crittenden‘s (Strategic Management Journal 24, 385–392, 2003) cross-cultural map of moral philosophies to examine what ethical criteria guide business people in Russia and the U.S. in their intention to behave. Competing divergence and convergence hypotheses were advanced. Our results support a convergence hypothesis, and reveal a common emphasis on relativism. Americans are also influenced by the justice criterion while Russians tend to emphasize utilitarianism. Rafik I.
