Literature Reviews in HCI: A Review of Reviews

This paper analyses Human-Computer Interaction (HCI) literature reviews to provide a clear conceptual basis for authors, reviewers, and readers. HCI is multidisciplinary and various types of literature reviews exist, from systematic to critical reviews in the style of essays. Yet, there is insufficient consensus of what to expect of literature reviews in HCI. Thus, a shared understanding of literature reviews and clear terminology is needed to plan, evaluate, and use literature reviews, and to further improve review methodology. We analysed 189 literature reviews published at all SIGCHI conferences and ACM Transactions on Computer-Human Interaction (TOCHI) up until August 2022. We report on the main dimensions of variation: (i) contribution types and topics; and (ii) structure and methodologies applied. We identify gaps and trends to inform future meta work in HCI and provide a starting point on how to move towards a more comprehensive terminology system of literature reviews in HCI

The 5T mouse multiple myeloma model: absence of c-myc oncogene rearrangement in early transplant generations.

Consistent chromosomal translocations involving the c-myc cellular oncogene and one of the three immunoglobin loci are typical for human Burkitt's lymphoma, induced mouse plasmacytoma (MPC) and spontaneously arising rat immunocytoma (RIC). Another plasma cell malignancy, multiple myeloma (MM), arising spontaneously in the ageing C57BL/KaLwRij mice, was investigated in order to see whether the MM cells contain c-myc abnormalities of the MPC or RIC type. Rearrangement of the c-myc oncogene was found in the bone marrow cells only in 5T2 MM transplantation line in a mouse of the 24th generation and in none of the seven other MM of the 5T series which were of earlier generations. Since the mouse 5T MM resembles the human MM very closely, including the absence of consistent structural c-myc oncogene abnormalities, it can serve as a useful experimental model for studies on the aetiopathogenesis of this disease

Comparing domain-and facet-level relations of the HEXACO personality model with workplace deviance

Personality research suggests that the prediction of organizational behavior can be improved by examining thecriterion-related validity of narrow personality facets. In the current study, we provide meta-analytic effect sizeestimates (k= 29) for the relations of all HEXACO domains and facets with workplace deviance and re-analyzeavailable data (k= 9) to compare the criterion-related validity of the HEXACO domains with that of theirconstituent facets. Findings provided evidence for a masking effect among the facets of Honesty-Humility and acancellation effect among the facets of Openness to Experience. Furthermore, facets generally outperformeddomains in predicting workplace deviance. This was most notable for the Fairness facet, which explained almostas much variance in workplace deviance as all six HEXACO domains combined. These results suggest that using afew HEXACO facets to predict workplace deviance can be more efficient than using all six broad domains

Wool cortisol as putative retrospective indicator of stress in ewes during the third trimester of pregnancy, and their newborns: effects of parity and litter size — an exploratory study

Stress is an important factor in animal welfare. Hair or wool cortisol concentrations are considered to be potential long-term indicators of stress experienced by an animal. Using Swifter sheep, we investigated whether ewe parity and litter size affect the wool cortisol concentrations in ewes and their offspring. We hypothesized that multiparous ewes and their offspring would have higher wool cortisol concentrations than primiparous ewes and their offspring, that ewes with larger litters and their offspring would have lower wool cortisol concentrations than ewes with smaller litters and their offspring, that male lambs would have higher wool cortisol concentrations than female lambs, and that the wool cortisol concentrations in the wool of ewes and their lambs would be correlated. Lamb wool grows in utero during the third trimester of pregnancy. In ewes, the shave–reshave method was used so that wool samples from ewes also covered approximately the last trimester of pregnancy. Our study confirmed that litter size affected ewe wool cortisol concentrations: ewes that gave birth to larger litters (i.e., 3 or 4 lambs) had higher wool cortisol concentrations than ewes that gave birth to smaller litters (i.e., 1 or 2 lambs). There was no evidence that the wool cortisol concentrations of the ewes and their lambs were correlated. Neither litter size nor parity of the ewe affected wool cortisol in the lambs. Our study confirms that wool cortisol can be reliably measured in ewes and their newborn lambs, and suggests that it may be useful as a retrospective indicator of stress during the last trimester of pregnancy

Bioelectromagnetics research within an Australian context: the Australian centre for electromagnetic bioeffects research (ACEBR)

Mobile phone subscriptions continue to increase across the world, with the electromagnetic fields (EMF) emitted by these devices, as well as by related technologies such as Wi-Fi and smart meters, now ubiquitous. This increase in use and consequent exposure to mobile communication (MC)-related EMF has led to concern about possible health effects that could arise from this exposure. Although much research has been conducted since the introduction of these technologies, uncertainty about the impact on health remains. The Australian Centre for Electromagnetic Bioeffects Research (ACEBR) is a National Health and Medical Research Council Centre of Research Excellence that is undertaking research addressing the most important aspects of the MC-EMF health debate, with a strong focus on mechanisms, neurodegenerative diseases, cancer, and exposure dosimetry. This research takes as its starting point the current scientific status quo, but also addresses the adequacy of the evidence for the status quo. Risk communication research complements the above, and aims to ensure that whatever is found, it is communicated effectively and appropriately. This paper provides a summary of this ACEBR research (both completed and ongoing), and discusses the rationale for conducting it in light of the prevailing science.Sarah P. Loughran ...

The discovery of endogenous retroviruses

When endogenous retroviruses (ERV) were discovered in the late 1960s, the Mendelian inheritance of retroviral genomes by their hosts was an entirely new concept. Indeed Howard M Temin's DNA provirus hypothesis enunciated in 1964 was not generally accepted, and reverse transcriptase was yet to be discovered. Nonetheless, the evidence that we accrued in the pre-molecular era has stood the test of time, and our hypothesis on ERV, which one reviewer described as 'impossible', proved to be correct. Here I recount some of the key observations in birds and mammals that led to the discovery of ERV, and comment on their evolution, cross-species dispersion, and what remains to be elucidated

A meta-analysis of the relations between personality and workplace deviance: Big Five versus HEXACO

We present a comprehensive meta-analysis of the relations between personality and workplace deviance. More specifically, we compared the validities of the Big Five domains with those of the HEXACO domains for predicting workplace deviance. We found that HEXACO Honesty-Humility shows the strongest relation with workplace deviance, followed by Conscientiousness (Big Five and HEXACO) and Agreeableness (Big Five and HEXACO). Big Five Neuroticism (positively) and HEXACO Emotionality (negatively) also correlate with workplace deviance. However, HEXACO and Big Five Openness to Experience and Extraversion do not contribute substantially to the prediction of workplace deviance. For the most part, these results support the conceptual differences between the Big Five and the HEXACO personality models. We also found that the HEXACO domains (31.97%) explain more variance in workplace deviance than the Big Five domains (19.05%). Consequently, the HEXACO model appears to be a viable alternative to the Big Five model when predicting and explaining levels of workplace deviance. Theoretical and practical implications of the findings as well as limitations and future research ideas are discussed

Systematic RADaR analysis of responses to the open-ended question in the Culture of Care Barometer survey of a Dutch hospital

OBJECTIVES: Systematically measuring the work environment of healthcare employees is key to continuously improving the quality of care and addressing staff shortages. In this study, we systematically analyse the responses to the one open-ended question posed in the Dutch version of the Culture of Care Barometer (CoCB-NL) to examine (1) if the responses offered new insights into healthcare employees' perceptions of their work environment and (2) if the original CoCB had any themes missing. DESIGN: Retrospective text analysis using Rigorous and Accelerated Data Reduction technique. SETTING: University hospital in the Netherlands using the CoCB-NL as part of the annual employee survey. PARTICIPANTS: All hospital employees were invited to participate in the study (N=14 671). In total, 2287 employees responded to the open-ended question. RESULTS: 2287 comments were analysed. Comments that contained more than one topic were split according to topic, adding to the total (n=2915). Of this total, 372 comments were excluded because they lacked content or respondents indicated they had nothing to add. Subsequently, 2543 comments were allocated to 33 themes. Most comments (n=2113) addressed the 24 themes related to the close-ended questions in the CoCB-NL. The themes most commented on concerned questions on 'organisational support'. The remaining 430 comments covered nine additional themes that addressed concerns about work environment factors (team connectedness, team effectiveness, corporate vision, administrative burden and performance pressure) and themes (diversity and inclusion, legal frameworks and collective bargaining, resilience and work-life balance, and personal matters). CONCLUSIONS: Analysing responses to the open-ended question in the CoCB-NL led to new insights into relevant elements of the work environment and missing themes in the COCB-NL. Moreover, the analysis revealed important themes that not only require attention from healthcare organisations to ensure adequate improvements in their employees' work environment but should also be considered to further develop the CoCB-NL.</p
