Microexpressions do exist, and they are regarded as valid cues to deception by many researchers, furthermore, there is a lot of empirical evidence which substantiates this claim. However, some researchers don’t think the microexpression can be a way to catch a liar. The author elucidates the theories predicting that looking for microexpressions can be a way to catch a liar, and notes that some data can support for the utilization of microexpressions as a good way to detect deception. In addition, the author thinks that the mixed results in the area of investigating microexpressions and deception detection may be moderated by the stake. More empirical studies which employ high-stake lies to explore the relationship between microexpressions and deception detection are needed.

The Relationship

Many mathematics educators believe a goal of instruction is for students to obtain conviction and certainty in mathematical statements using the same types of evidence that mathematicians do. However, few empirical studies have examined how mathematicians use proofs to obtain conviction and certainty. We report on a study in which 16 advanced mathematics doctoral students were given a task-based interview in which they were presented with various sources of evidence in support of a specific mathematical claim and were asked how convinced they were that the claim was true after reviewing this evidence. In particular, we explore why our participants retained doubts about our claim after reading its proof and how they used empirical evidence to reduce those doubts.

Purpose This study aims to examine the relationship between corporate governance and the likelihood of corporate fraud in Malaysia. Design/methodology/approach The sample of fraudulent companies in this study is the public listed companies that were charged with furnishing false statements to the Securities Commission of Malaysia and Bursa Malaysia Securities Berhad and was listed in the Malaysian Securities Commission Enforcement Release from the year 2000 to 2016. The non-fraudulent companies, which are the control companies in this study, were selected from public listed companies listed in Bursa Malaysia, based on their similarity to the fraudulent companies in terms of time, size and industry type. The panel probit regression analysis was used to examine the relationship between corporate governance characteristics and the occurrence of corporate fraud. Findings The findings of this study suggest that board size and executive directors’ compensation are the corporate governance characteristics that can effectively combat corporate fraud incidences in Malaysia. The corporate governance features, namely the board of directors’ independence, frequency of board meetings, CEO duality, CEO’s age, and share ownership owned by directors and CEO, do not significantly influence corporate fraud incidences in Malaysia. Originality/value Although previous studies provide inconsistent findings on the association between board size and corporate fraud incidences, this study contributes to the existing literature by providing empirical evidence that smaller board sizes provide more effective monitoring functions to minimize corporate fraud incidences in the Malaysian context. The empirical evidence also supports the agency theory proposition where managers with high compensation will act in the best interest of shareholders and less likely to focus on their interests, thus deterring them from committing fraudulent acts.

Insight Into

This chapter presents empirical evidence regarding the (in)effectiveness of prisons for reducing crime. The authors begin with a brief discussion of the mechanisms through which incarceration affects crime, followed by a review of research that presents empirical evidence on the relationship between prisons and crime. This section separates empirical research on the total effect of prison on crime from empirical studies intended to isolate the deterrent or incapacitation effects of prison. Death penalty studies are also reviewed for insight into whether capital punishment has any short- or long-term effects on homicide rates. The chapter concludes with a brief discussion of the policy implications that follow from the empirical research on prison effects on crime.

Throughout history it has been assumed that lying is accompanied by specific nonverbal behaviors; various sources still claim that nonverbal behavior is very revealing about deception. Systematic research, however, examining nonverbal cues to deceit has shown that nonverbal cues to deceit are faint and unreliable. This chapter starts with discussing under which circumstances people pay attention to nonverbal behavior and provides reasons why they do so. This is followed by a theoretical background of nonverbal cues to deception and discussions of the (weak) empirical evidence about (1) the relationship between nonverbal cues and deception, including the empirical evidence regarding the Behavior Analysis Interview and Ekman’s approach of observing facial expressions, and (2) people’s (poor) ability to detect deceit when paying attention to nonverbal behavior. Despite the popularity of observing nonverbal behavior to detect deception, analyzing speech content provides more accurate results, particularly when specific interview protocols are used.

The European Union’s neighbourhood is complex and still far from being stable. In Ukraine, significant progress has occurred in many areas of transition; however, much work remains to be done, especially in the field of regional development and governance where many legacies of the Soviet model remain. At the crossroads between East and West, Ukraine presents an interesting case of policy development as an expression of European Union (EU) external governance. This paper asks the question: why was the relationship between the EU and Ukraine fairly unsuccessful at promoting stability in the region and in Ukraine? What was missing in the European Neighbourhood Policy (ENP) in Ukraine that rendered the EU unable to prevent a conflict on the ground? By identifying security, territorial, and institutional challenges and opportunities the EU has faced in Ukraine, this paper underlines the most important factors accounting for the performance of its external governance and crisis management in Ukraine.   Full text available at: https://doi.org/10.22215/rera.v12i2.1310

This chapter summarizes current interpretations of all forms of confabulations discussed in the book and reviews the relationship between the four forms of memory-related confabulations. Experimental investigation has confirmed the dissociation between various types of false memories and considerably advanced the understanding of the mechanisms of some forms of confabulation, in particular behaviourally spontaneous confabulation and false statements in anosognosia. Overall, experimental evidence is scarce; many models have no controlled experimental basis or extend their proposed range of application well beyond the empirical evidence. The chapter concludes with a call for heightened respect of basic scientific standards in the research on confabulation.

Striking Fact

The chapter argues that empirical studies of first-language acquisition lend support to the Wittgensteinian-Merleau-Pontian conception of language as against the prevailing conception that underwrites the method of cases in either its armchair or experimental version. It offers a non-representationalist model, inspired by the work of Michael Tomasello, for the acquisition of “knowledge,” with the aim of showing that we could fully account for the acquisition of this and other philosophically troublesome words without positing independently existing “items” to which these words refer. The chapter also aims at bringing out and underscoring the striking fact that, whereas many in contemporary analytic philosophy regard and present themselves as open and attentive to empirical science, they have often relied on a conception of language that has been supported by no empirical evidence.

The Way

The environment has always been a central concept for archaeologists and, although it has been conceived in many ways, its role in archaeological explanation has fluctuated from a mere backdrop to human action, to a primary factor in the understanding of society and social change. Archaeology also has a unique position as its base of interest places it temporally between geological and ethnographic timescales, spatially between global and local dimensions, and epistemologically between empirical studies of environmental change and more heuristic studies of cultural practice. Drawing on data from across the globe at a variety of temporal and spatial scales, this volume resituates the way in which archaeologists use and apply the concept of the environment. Each chapter critically explores the potential for archaeological data and practice to contribute to modern environmental issues, including problems of climate change and environmental degradation. Overall the volume covers four basic themes: archaeological approaches to the way in which both scientists and locals conceive of the relationship between humans and their environment, applied environmental archaeology, the archaeology of disaster, and new interdisciplinary directions.The volume will be of interest to students and established archaeologists, as well as practitioners from a range of applied disciplines.
