Contextual considerations for deception production and detection in forensic interviews
7 pagesMost deception scholars agree that deception production and deception detection
effects often display mixed results across settings. For example, some liars use more
emotion than truth-tellers when discussing fake opinions on abortion, but not
when communicating fake distress. Similarly, verbal and nonverbal cues are often
inconsistent predictors to assist in deception detection, leading to mixed accuracies
and detection rates. Why are lie production and detection effects typically inconsistent?
In this piece, we argue that aspects of the context are often unconsidered in how lies
are produced and detected. Greater theory-building related to contextual constraints
of deception are therefore required. We reintroduce and extend the Contextual
Organization of Language and Deception (COLD) model, a framework that outlines
how psychological dynamics, pragmatic goals, and genre conventions are aspects of
the context that moderate the relationship between deception and communication
behavior such as language. We extend this foundation by proposing three additional
aspects of the context — individual differences, situational opportunities for deception,
and interpersonal characteristics — for the COLD model that can specifically inform
and potentially improve forensic interviewing. We conclude with a forward-looking
perspective for deception researchers and practitioners related to the need for more
theoretical explication of deception and its detection related to the context
Managing ‘difference’: understanding age diversity in practice
This article explores how human resource (HR) managers discuss, classify and justify age diversity as both a concept and practice within the UK. The findings from 33 in-depth interviews with HR managers reveal difficulty in translating age diversity as an abstract managerial concept into workfloor policy and practice. Whilst the managers sought to emphasise the role of culture in promoting diversity, there was a lack of evidence that this related to workfloor equality or activities that proactively challenge discrimination. Moreover, there was confusion over classifying older workers as ‘diverse’, and risking possible discriminatory practices which marginalised both the older workers and other employees. The conclusions discuss how the ambiguous concept of ‘difference’ which lies at the basis of understanding both diversity and discrimination caused tension when implementing older worker strategies, and how policy makers must provide clear measures concerning the intent, objectives and definitions surrounding age equality. It is argued that a move towards an action model of discrimination management may help to create a framework where diversity and discrimination can be mutually addressed
The Effect of Algorithms on Copy Number Variant Detection
BACKGROUND: The detection of copy number variants (CNVs) and the results of CNV-disease association studies rely on how CNVs are defined, and because array-based technologies can only infer CNVs, CNV-calling algorithms can produce vastly different findings. Several authors have noted the large-scale variability between CNV-detection methods, as well as the substantial false positive and false negative rates associated with those methods. In this study, we use variations of four common algorithms for CNV detection (PennCNV, QuantiSNP, HMMSeg, and cnvPartition) and two definitions of overlap (any overlap and an overlap of at least 40% of the smaller CNV) to illustrate the effects of varying algorithms and definitions of overlap on CNV discovery. METHODOLOGY AND PRINCIPAL FINDINGS: We used a 56 K Illumina genotyping array enriched for CNV regions to generate hybridization intensities and allele frequencies for 48 Caucasian schizophrenia cases and 48 age-, ethnicity-, and gender-matched control subjects. No algorithm found a difference in CNV burden between the two groups. However, the total number of CNVs called ranged from 102 to 3,765 across algorithms. The mean CNV size ranged from 46 kb to 787 kb, and the average number of CNVs per subject ranged from 1 to 39. The number of novel CNVs not previously reported in normal subjects ranged from 0 to 212. CONCLUSIONS AND SIGNIFICANCE: Motivated by the availability of multiple publicly available genome-wide SNP arrays, investigators are conducting numerous analyses to identify putative additional CNVs in complex genetic disorders. However, the number of CNVs identified in array-based studies, and whether these CNVs are novel or valid, will depend on the algorithm(s) used. Thus, given the variety of methods used, there will be many false positives and false negatives. Both guidelines for the identification of CNVs inferred from high-density arrays and the establishment of a gold standard for validation of CNVs are needed
Sustainability of Nutraceuticals and Functional Foods
Sustainability challenges and issues in nutraceuticals and functional foods arena have influenced
both consumers and the industrial sector. Though the present day can be termed as an era of
nutraceuticals and functional foods, the knowledge on sustainability among the people involved is
limited in the pharma‐food industry. In this chapter, we provide a general overview of this subject,
followed by discussion on the four pillars of sustainability and how these relate to the agricultural
system, food safety and food security. Examples of nutraceuticals products, health benefits incurred,
consumer trends and food choices as well as market values are all examined
Physician Awareness of Drug Cost: A Systematic Review
From a review of data from 24 studies, Michael Allan and colleagues conclude that doctors often underestimate the price of expensive drugs and overestimate the price of those that are inexpensive
The Effect of Fluid Intake Following Dehydration on Subsequent Athletic and Cognitive Performance: a Systematic Review and Meta-analysis
Joy leads to overconfidence, and a simple countermeasure
Overconfidence has been identified as a source of suboptimal decision making in many real-life domains, with often far-reaching consequences. This study identifies a mechanism that can cause overconfidence and demonstrates a simple, effective countermeasure in an incentive-compatible experimental study. We observed that joy induced overconfidence if the reason for joy (an unexpected gift) was u
More than competition: exploring stakeholder identities at a grassroots cause-related sporting event
The purpose of this paper is to (a) explore stakeholder identities of a grassroots cause-related sporting event; and (b) gain a better understanding of how identities are related to stakeholder development, support of the event, and future intentions. We used a mixed methods research design that consisted of two studies: qualitative followed by quantitative. Study 1 explored stakeholder identities and how they are related to stakeholder development and support of the event, and Study 2 examined how future intentions regarding attendance, donations, and sponsor support differ based on levels of stakeholder identity. Sports marketing and non-profit management literature streams as well as identity theory and social capital theory informed our studies. The National Kidney Foundation Surf Festival was selected because it is a grassroots cause-related sporting event with financial success over the last two decades. In addition, a surf contest, an action sport, is a unique sport setting in the nonprofit sector, which offers insight to marketers seeking to target subcultures. The findings of the qualitative study revealed three identities relevant to participants: sport subculture, community, and cause. A framework emerged from the data that illustrated how these identities unite together to generate social capital, which is linked to effective volunteer and sponsorship management. Quantitative analysis through survey data provided further evidence of the impact of identification with a cause-related sport activity on consumer outcomes. Results indicated attendees with high surf-related identity are more likely to attend future Surf Festivals, have higher intentions to donate to the cause, and have higher sponsor purchase intentions compared to those with low self-identity with the sport subculture. The conclusion discusses implications, framing the findings through the intersection of the sports marketing and non-profit sector industries, and provides suggestions for future research.Ye
Cross Adaptation - Heat and Cold Adaptation to Improve Physiological and Cellular Responses to Hypoxia
To prepare for extremes of heat, cold or low partial pressures of O2, humans can undertake a period of acclimation or acclimatization to induce environment specific adaptations e.g. heat acclimation (HA), cold acclimation (CA), or altitude training. Whilst these strategies are effective, they are not always feasible, due to logistical impracticalities. Cross adaptation is a term used to describe the phenomenon whereby alternative environmental interventions e.g. HA, or CA, may be a beneficial alternative to altitude interventions, providing physiological stress and inducing adaptations observable at altitude. HA can attenuate physiological strain at rest and during moderate intensity exercise at altitude via adaptations allied to improved oxygen delivery to metabolically active tissue, likely following increases in plasma volume and reductions in body temperature. CA appears to improve physiological responses to altitude by attenuating the autonomic response to altitude. While no cross acclimation-derived exercise performance/capacity data have been measured following CA, post-HA improvements in performance underpinned by aerobic metabolism, and therefore dependent on oxygen delivery at altitude, are likely. At a cellular level, heat shock protein responses to altitude are attenuated by prior HA suggesting that an attenuation of the cellular stress response and therefore a reduced disruption to homeostasis at altitude has occurred. This process is known as cross tolerance. The effects of CA on markers of cross tolerance is an area requiring further investigation. Because much of the evidence relating to cross adaptation to altitude has examined the benefits at moderate to high altitudes, future research examining responses at lower altitudes should be conducted given that these environments are more frequently visited by athletes and workers. Mechanistic work to identify the specific physiological and cellular pathways responsible for cross adaptation between heat and altitude, and between cold and altitude, is warranted, as is exploration of benefits across different populations and physical activity profiles
