In experiments, researchers commonly allocate subjects randomly and equally to the different treatment conditions before the experiment starts. While this approach is intuitive, it means that new information gathered during the experiment is not utilized until after the experiment has ended. Based on methodological approaches from other scientific disciplines such as computer science and medicine, we suggest machine learning algorithms for subject allocation in experiments. Specifically, we discuss a Bayesian multi-armed bandit algorithm for randomized controlled trials and use Monte Carlo simulations to compare its efficiency with randomized controlled trials that have a fixed and balanced subject allocation. Our findings indicate that a randomized allocation based on Bayesian multi-armed bandits is more efficient and ethical in most settings. We develop recommendations for researchers and discuss the limitations of our approach.
在实验中,研究人员通常在实验开始前将受试者随机平均地分配到不同的处理条件中。虽然这种方法是直观的,但它意味着在实验期间收集的新信息直到实验结束后才被利用。基于其他科学学科(如计算机科学和医学)的方法论方法,我们建议在实验中使用机器学习算法来分配受试者。具体来说,我们讨论了随机对照试验的贝叶斯多臂强盗算法,并使用蒙特卡罗模拟比较了其与具有固定和平衡受试者分配的随机对照试验的效率。我们的研究结果表明,在大多数情况下,基于贝叶斯多武装强盗的随机分配更有效和道德。我们为研究人员提出建议,并讨论我们方法的局限性。

Latent variable models and interaction effects have both been common in the organizational sciences for some time. Methods for incorporating interactions into latent variable models have existed since at least Kenny and Judd, and a great many articles and books have developed these methods further. In the present article, we present an empirical review of the methods that organizational science investigators use to test their interaction hypotheses. We show that it is very common for investigators to use fully latent methods to test additive portions of their models, but to abandon such methods when testing the multiplicative portions of their models. By contrast, investigators whose models do not contain interactions tend to stick with fully latent methods throughout. As there is little rational basis for this pattern, it is likely due to continued discomfort regarding the proper application of existing fully latent methods. Thus, we end by offering R code that implements some of the more sophisticated fully latent approaches, and by offering a sequence of decisions that investigators can follow in order to choose the best analytic approach.
一段时间以来,潜在变量模型和交互效应在组织科学中都很常见。至少从Kenny和Judd开始就存在将相互作用纳入潜在变量模型的方法,许多文章和书籍对这些方法进行了进一步的发展。在本文中,我们对组织科学研究人员用来测试他们的互动假设的方法进行了实证回顾。我们表明,研究人员使用完全潜在的方法来测试其模型的加法部分是非常常见的,但在测试模型的乘法部分时放弃了这种方法。相比之下,那些模型中不包含相互作用的研究人员往往始终坚持完全潜在的方法。由于这种模式几乎没有合理的依据,这可能是由于对现有的完全潜在方法的正确应用持续感到不适。因此,我们最终提供了实现一些更复杂的完全潜在方法的R代码,并提供了一系列决策,调查人员可以遵循这些决策来选择最佳的分析方法。

Trends toward convergence on common methodologies and standardized templates restrict the diversity of qualitative methods in organizational research. Considering that graduate education is a critical process in the socialization of researchers into the norms and dominant practices of their discipline, graduate students’ socialization into research methodologies is vital for understanding methodological convergence. The purpose of our study was to understand how graduate students’ socialization shapes their methodological and paradigmatic preferences. Showcasing methodological bricolage as an alternative to qualitative templates, we constructed a research design that combined thematic, discourse, and narrative analyses to investigate graduate students’ reflections throughout a qualitative methods course introducing alternative research paradigms. Our findings highlight the role of institutional, disciplinary, and personal influences as well as identity work in researchers’ socialization and trace alternative trajectories by which socialization and methodological identity construction processes may unfold. We offer a sketch of methodological socialization and suggest that its understanding should be central to nurturing paradigmatic and methodological plurality in qualitative research. We conclude with implications for future research and for research methods training.
通用方法和标准化模板趋同的趋势限制了组织研究中定性方法的多样性。考虑到研究生教育是研究人员融入学科规范和主导实践的关键过程,研究生融入研究方法论对于理解方法论趋同至关重要。我们研究的目的是了解研究生的社会化如何塑造他们的方法论和范式偏好。展示了方法论拼凑作为定性模板的替代方案,我们构建了一个研究设计,结合主题、话语和叙事分析,在引入替代研究范式的定性方法课程中调查研究生的反思。我们的研究结果强调了制度、学科和个人影响以及身份工作在研究人员社会化中的作用,并追踪了社会化和方法论身份构建过程可能展开的替代轨迹。我们提供了一个方法论社会化的草图,并建议对其的理解应该是在定性研究中培养范式和方法论多样性的核心。最后,我们对未来的研究和研究方法培训提出了建议。

Citation context analysis is a detailed and rigorous form of literature review that goes beyond traditional narrative and systematic reviews to better understand the impact of seminal works and influential authors. We discuss the types of questions citation context analyses can answer and provide a set of guidelines for how to effectively conduct them. Citation context analysis holds promise for enabling a more systematic assessment of how theories are used, empirically tested, and critiqued by subsequent citing authors. This has implications for both theory development and testing, and for the improvement of citation practices within the field of organizational studies and the social and physical sciences more broadly.
引文上下文分析是一种详细而严谨的文献综述形式,它超越了传统的叙事和系统综述,可以更好地理解开创性作品和有影响力的作者的影响。我们讨论了引文上下文分析可以回答的问题类型,并为如何有效地进行引文上下文分析提供了一套指导方针。引文上下文分析有望对理论如何被使用、实证检验和随后的引用作者的批评进行更系统的评估。这对理论发展和测试,以及对组织研究和更广泛的社会科学和物理科学领域的引用实践的改进都有影响。

From Templates to Heuristics: How and Why to Move Beyond the Gioia Methodology 从模板到启发式:如何以及为什么超越Gioia方法论

Researchers are exposed to multiple interpretive challenges in the journey from field data to theoretical understanding. A common response to these challenges is to turn to the guidance of templates such as the Gioia methodology—currently a preferred template for interpretive management research. Given its popularity, we examine how this methodology approaches the interpretive process of fieldwork. We find that the inductive route to theory that it offers does not address the challenges of interpretation. As an alternative, we propose a return to the epistemological tradition of hermeneutics. We argue that fieldwork informed by a hermeneutic orientation is able to generate credible and novel theory by confronting the challenges of interpretation head on. This process cannot be represented by the orderly steps of a template. We argue that a return to a hermeneutic orientation opens the way to more plausible and insightful theories based on interpretive rather than procedural rigor, and we offer a set of heuristics to guide both researchers and reviewers along this path.
在从实地数据到理论理解的过程中,研究人员面临着多重解释挑战。对这些挑战的一个常见回应是求助于Gioia方法论等模板的指导——这是目前解释性管理研究的首选模板。鉴于其受欢迎程度,我们研究了这种方法如何接近实地调查的解释过程。我们发现,它提供的归纳理论路线并没有解决解释的挑战。作为一种选择,我们建议回归解释学的认识论传统。我们认为,以解释学为导向的田野调查能够通过直面解释的挑战来产生可信的、新颖的理论。这一过程不能用模板的有序步骤来表示。我们认为,回归解释学取向为基于解释而非程序严谨的更合理和更有洞察力的理论开辟了道路,我们提供了一套启发式方法来指导研究人员和评论家沿着这条道路前进。

Text Preprocessing for Text Mining in Organizational Research: Review and Recommendations 组织研究中用于文本挖掘的文本预处理:综述和建议

Recent advances in text mining have provided new methods for capitalizing on the voluminous natural language text data created by organizations, their employees, and their customers. Although often overlooked, decisions made during text preprocessing affect whether the content and/or style of language are captured, the statistical power of subsequent analyses, and the validity of insights derived from text mining. Past methodological articles have described the general process of obtaining and analyzing text data, but recommendations for preprocessing text data were inconsistent. Furthermore, primary studies use and report different preprocessing techniques. To address this, we conduct two complementary reviews of computational linguistics and organizational text mining research to provide empirically grounded text preprocessing decision-making recommendations that account for the type of text mining conducted (i.e., open or closed vocabulary), the research question under investigation, and the data set’s characteristics (i.e., corpus size and average document length). Notably, deviations from these recommendations will be appropriate and, at times, necessary due to the unique characteristics of one’s text data. We also provide recommendations for reporting text mining to promote transparency and reproducibility.
文本挖掘的最新进展为利用由组织、其员工和其客户创建的大量自然语言文本数据提供了新的方法。虽然经常被忽视,但在文本预处理期间做出的决定会影响是否捕获语言的内容和/或风格、后续分析的统计能力以及从文本挖掘中获得的见解的有效性。过去的方法学文章描述了获取和分析文本数据的一般过程,但是关于预处理文本数据的建议并不一致。此外,初步研究使用并报告了不同的预处理技术。为了解决这个问题,我们对计算语言学和组织文本挖掘研究进行了两个互补的回顾,以提供基于经验的文本预处理决策建议,这些建议考虑了所进行的文本挖掘的类型(即开放或封闭词汇)、正在调查的研究问题和数据集的特征(即语料库大小和平均文档长度)。值得注意的是,由于文本数据的独特特性,偏离这些建议是适当的,有时也是必要的。我们还为报告文本挖掘提供了建议,以提高透明度和可重复性。

Discriminant validity was originally presented as a set of empirical criteria that can be assessed from multitrait-multimethod (MTMM) matrices. Because datasets used by applied researchers rarely lend themselves to MTMM analysis, the need to assess discriminant validity in empirical research has led to the introduction of numerous techniques, some of which have been introduced in an ad hoc manner and without rigorous methodological support. We review various definitions of and techniques for assessing discriminant validity and provide a generalized definition of discriminant validity based on the correlation between two measures after measurement error has been considered. We then review techniques that have been proposed for discriminant validity assessment, demonstrating some problems and equivalencies of these techniques that have gone unnoticed by prior research. After conducting Monte Carlo simulations that compare the techniques, we present techniques called CICFA(sys) and χ 2 (sys) that applied researchers can use to assess discriminant validity.
判别有效性最初是作为一组经验标准提出的,可以从多特征多方法(MTMM)矩阵中进行评估。由于应用研究人员使用的数据集很少用于MTMM分析,因此在实证研究中评估判别有效性的需要导致了许多技术的引入,其中一些技术是以临时的方式引入的,没有严格的方法支持。我们回顾了判别有效性的各种定义和评估技术,并在考虑测量误差后,基于两个度量之间的相关性,提供了判别有效度的广义定义。然后,我们回顾了已经提出的用于判别有效性评估的技术,证明了这些技术的一些问题和等效性,这些问题和等价性在以前的研究中没有被注意到。在对这些技术进行蒙特卡罗模拟比较后,我们提出了被称为CICFA(sys)和χ2(sys)的技术,应用研究人员可以使用这些技术来评估判别有效性。

We examine an underaddressed issue in organizational research, the nature of the politicization of knowledge and its consequences for conducting research. Drawing on an illustrative case from a PhD research study and the underutilized theory of politicization, we go beyond previous work on politics in organization and management research to offer three contributions. First, we develop a process model underscoring the potentially emergent and interwoven nature of the politicization of research. In particular, we suggest politicization be seen as a trajectory of moments of difference in which researchers may or may not be aware of the potential political significance. Second, we offer four analytical resources to help researchers make sense around why politicization may occur: disputes over the “ownership” of knowledge, clashes of representational logics, ideological differences, and identity struggles. Third, we argue that politicization can be a catalyst, rather than an obstacle, for knowledge production and propose ways of anticipating and negotiating differences. Our aim is to raise awareness of the importance of understanding and anticipating the politicized situations researchers may encounter in their work.
我们研究了组织研究中一个未被充分解决的问题,即知识政治化的本质及其对开展研究的后果。借鉴博士研究中的一个说明性案例和未充分利用的政治化理论,我们超越了先前在组织和管理研究中的政治工作,提供了三个贡献。首先,我们开发了一个过程模型,强调了研究政治化的潜在新兴和相互交织的本质。特别是,我们建议将政治化视为研究人员可能或可能没有意识到潜在政治意义的差异时刻的轨迹。其次,我们提供了四种分析资源来帮助研究人员理解为什么会发生政治化:知识“所有权”的争议、表征逻辑的冲突、意识形态差异和身份斗争。第三,我们认为政治化可以成为知识生产的催化剂,而不是障碍,并提出了预测和协商分歧的方法。我们的目的是提高人们对理解和预测研究人员在工作中可能遇到的政治化情况的重要性的认识。

Second, we offer four analytical resources to help researchers make sense around why politicization may occur: disputes over the “ownership” of knowledge, clashes of representational logics, ideological differences, and identity struggles. Third, we argue that politicization can be a catalyst, rather than an obstacle, for knowledge production and propose ways of anticipating and negotiating differences. Our aim is to raise awareness of the importance of understanding and anticipating the politicized situations researchers may encounter in their work.","PeriodicalId":19689,"journal":{"name":"Organizational Research Methods","volume":"25 1","pages":"88 - 113"},"PeriodicalIF":9.5,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1094428120969884","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48212280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Systematic reviews of academic research have not impacted management practice as much as many researchers had hoped. Part of the reason is that researchers and managers differ significantly in their knowledge systems—in both what they know and how they know it. Researchers can overcome some of these challenges by including managers as knowledge partners in the research endeavor; however, doing so is rife with challenges. This article seeks to answer, how can researchers and managers navigate the tensions related to differences in their knowledge systems to create more impactful systematic reviews? To answer this question, we embarked on a data-guided journey of the experience of the Network for Business Sustainability, which had undertaken 15 systematic reviews that involved researchers and managers. We interviewed previous participants of the projects, observed different systematic review processes, and collected archival data to learn more about researcher-manager collaborations in the systematic review process. This article offers guidance to researchers in imbricating academic with practical knowledge in the systematic review process.
学术研究的系统评论并没有像许多研究人员所希望的那样对管理实践产生影响。部分原因是研究人员和管理人员的知识体系存在显著差异——无论是他们知道什么,还是他们如何知道。研究人员可以通过将管理者作为研究工作中的知识伙伴来克服其中的一些挑战;然而,这样做充满了挑战。本文试图回答,研究人员和管理人员如何驾驭与他们的知识体系差异相关的紧张关系,以创造更有影响力的系统评价?为了回答这个问题,我们开始了一段以数据为指导的商业可持续发展网络(Network for Business Sustainability)的经验之旅,该网络进行了15次系统审查,涉及研究人员和管理人员。我们采访了以前的项目参与者,观察了不同的系统评审过程,并收集了档案数据,以了解更多关于研究人员-管理者在系统评审过程中的合作。本文为研究人员在系统评价过程中如何将学术知识与实践知识相结合提供了指导。
