Survey research is appropriate and necessary to address certain types of research questions. In this paper, we acknowledge the ongoing debate about survey research and focus specifically on examining the conditions under which a study might validly utilize data provided by a single respondent. To this end, we summarize the main challenges that survey research in supply chain management faces when dealing with single respondents and later argue that having multiple respondents does not necessarily represent a cure‐all solution. Next, we discuss the concept of alignment in survey research and explore the characteristics of research questions that can be addressed through single key informants. We conclude the paper by suggesting that researchers should carefully consider the appropriateness of single key informants in light of the type of research question and also clearly support such choice when describing the method adopted. 相似文献

通过1/1万的高精度磁法测量,在哈西亚图地区圈出了C1、C2、C3三个异常,从目前成果看,矿致异常的异常特征很明显:异常为南正北负,正磁异常大于负磁异常,峰值较高,当△T在3000 nT-8000nT区间时,梯度陡的磁异常区域,磁铁矿体埋藏深度较浅,一般小于20m,当△T大于8000 nT时,地表可揭露出磁铁矿(化)体。此次普查工作大致查明C2-1、C3磁异常为矿致异常,含矿岩性为矽卡岩,矿床属似层状矽卡岩型铁多金属矿床[4]。 相似文献

Sustainable supply management research generally focuses on environmental practices. We show through an analysis of the food industry that sustainability requires an expanded view to encompass both environmental and social elements. We interviewed and surveyed food and beverage producers in the U.S. Pacific Northwest to both validate expanded sustainability elements in the industry and assess subsequent performance outcomes. A path analysis reveals that food industry managers perceive both direct and mediated impacts of sustainability programs on performance. Specifically, the results indicate that sustainability program effects are limited to the impact of conservation and land management environmental practices on overall environmental performance and human resources practices on quality performance. However, environmental performance improvements lead to improved quality performance, which in turn improves cost performance. The results highlight the complexity of sustainability impacts on performance and suggest that performance benefits from sustainability programs may be difficult to recognize. 相似文献

We study the importance of individual characteristics and national factors influencing individual attitudes towards the impact of multinational corporations on local businesses. Our sample includes more than 40 000 respondents in 29 countries from the 2003 National Identity Survey conducted by the International Social Survey Programme. We find that individual demographic factors and socioeconomic status, such as gender, age, income and education, are strong predictors of their attitudes. For example, income and education are positively associated with favourable attitudes towards the impact of multinational corporations (MNCs) on local businesses while age is negatively associated with individual attitudes towards MNCs. In addition, hierarchical ordered logit model results show that approximately 8% of total variations in individual attitudes around our sample mean are not explained by differences in personal traits. Instead, they are due to country-level heterogeneity such as, but not limited to, different degrees of openness or different aggregate income. 相似文献

近年来,伴随互联网的发展与普及,中国社会主义民主政治也出现了一些新变化,公民网络政治参与已经发展为一种普遍的政治现象,随着政府主动积极地构建各种制度化的公民参政与政府反馈机制,一种独具中国特色的网络公共领域形态逐渐孕育和发展起来。目前中国网络公共领域尚处于不成熟的发展阶段,与现实政治过程有较强的互动性,对其进行具体的理论考察,揭示这种新型民主形态的实践过程与内在逻辑,不仅对中国公民社会的有序、健康发展起到重要的推动作用,而且为中国民主政治的发展寻求了一条有效途径。 相似文献
