Investigating and preventing scientific misconduct using Benford’s Law

Integrity and trust in that integrity are fundamental to academic research. However, procedures for monitoring the trustworthiness of research, and for investigating cases where concern about possible data fraud have been raised are not well established. Here we suggest a practical approach for the investigation of work suspected of fraudulent data manipulation using Benford’s Law. This should be of value to both individual peer-reviewers and academic institutions and journals. In this, we draw inspiration from well-established practices of financial auditing. We provide synthesis of the literature on tests of adherence to Benford’s Law, culminating in advice of a single initial test for digits in each position of numerical strings within a dataset. We also recommend further tests which may prove useful in the event that specific hypotheses regarding the nature of data manipulation can be justified. Importantly, our advice differs from the most common current implementations of tests of Benford’s Law. Furthermore, we apply the approach to previously-published data, highlighting the efficacy of these tests in detecting known irregularities. Finally, we discuss the results of these tests, with reference to their strengths and limitations.Publisher PDFPeer reviewe

Artificial light at night may decrease predation risk for terrestrial insects

This work was supported by the University of St Andrews.Artificial light at night (ALAN) is thought to be detrimental for terrestrial insect populations. While there exists evidence for lower abundance under ALAN, underlying mechanisms remain unclear. One mechanism by which ALAN may contribute to insect declines may be through facilitating increased predation. We investigated this by experimentally manipulating insect-substitute abundance under differential levels of light. We used insect-containing birdfeed placed at varying distances from streetlights as a proxy for terrestrial insects, inspecting the rate of predation before and after dusk (when streetlights are, respectively, off and on). We found that there was a significantly greater effect of increasing distance on predation after dusk, suggesting that predation was actually reduced by greater levels of artificial light. This may occur because ALAN also increases the vulnerability of insectivores to their own predators. Implications for foraging behaviour and alternative explanations are discussed.Publisher PDFPeer reviewe

Millennials as potential creative tourists in South Africa:A CHAID approach to market segmentation

Creative tourism has recently emerged as an important area of tourism development, particularly in the Global North. In the Global South, studies of the profile of creative tourists and their motives for partaking in creative tourism are limited. This paper investigates creative tourism demand among South African millennials, analysing what motivates their participation and developing a descriptive consumer profile. CHAID analysis was used for segmentation, revealing a group with a high participation intention and a second group with a low probability of creative tourism participation. Creative tourism intentions were linked to knowledge acquisition, skills and escape motivations, and demographic characteristics including relationship status and gender. Respondents were more likely to participate in domestic rather than international creative tourism, indicating the potential for creative tourism development in South Africa. The findings could help managers and policymakers meet the needs of creative tourists, addressing shortfalls in product development, experience design and marketing

\u27Ice in the Family\u27: Exploring the experiences of close family members when another family member is using methamphetamine: A longitudinal qualitative study

Objective: To explore the experiences of close family members when another family member is using methamphetamine and how the family member responds over time. Background: Methamphetamine use has widespread implications and harms for both people who use the drug and those that live with them. While there is a significant representation in the literature relating to family members of people who use drugs or alcohol, there are limited studies specifically considering family members experiences of methamphetamine use. Families have been shown to have both positive and negative impacts on people using drugs, but less is known on the impact on the family members themselves. Study design and methods: Multiple semistructured qualitative interviews were conducted with 11 families (17 individual participants) from regional and metropolitan Western Australia over a 12-month period. Interpretative Phenomenological Analysis was used in data collection and analysis. Results: Four main themes were identified: 1. The New Lifeguard describes family members’ unplanned insertion into a new role and their rapidly changing experience of the person using methamphetamine. 2. Hit by the Wave demonstrates participants’ experience of repeated and unpredictable impacts on their lives. 3. Life in the Ocean describes the groundlessness associated with changes to goals and family structure. 4. Learning to Surf illuminates the changing strategies employed over time, moving away from trying to fix the person, to participants managing their own wellbeing. Discussion: This study identified common aspects within the lived experience of close family members of people using methamphetamine and ascertained a commonality in the process of this experience. Significant impacts to all areas of life were reported, and distress was fluctuating and unpredictable in line with the cyclical nature of the drug use. Participant responses to these changes varied over time between resentment and trying to fix things, and acceptance and resilience, while gaining or maintaining like-minded supports. Conclusion: Understanding the issues faced by families around this unique drug is vital in providing informed interventions for this group. Family members experience a broad range of financial, social and health impacts and harms over a protracted length of time. They are often not the focus of available support and in adapting to these issues, will themselves seek support away from treatment services for the person using methamphetamine. Implications for practice: Understanding the complex journey of families has a broad range of implications (and opportunities) for a variety of areas such as criminal justice, family support and child protection. There is an opportunity for these areas to consider broader and more specific supports and approaches, and to develop more appropriate, bespoke, and inclusive treatment for families of people using methamphetamine. What is already known about the topic? Methamphetamine is recognised worldwide as a harmful drug with few effective treatments for methamphetamine dependence. Few studies exist exploring the specific impact of methamphetamine on family members. Fewer studies explore the experiences over time. What this paper adds: Family members with a relative who is using methamphetamine experience a range of harms in many areas of their lives. The impact of methamphetamine use is unpredictable and takes place over long periods of time, affecting both individual family members and impacting on the overall structure of the family unit. Families and family members adapt their approach over time, from attempting to fix the situation, to stepping back and seeking support from others who they perceive to be in similar circumstances

A survey of attitudes toward visual training in the Northwest

A questionnaire was sent to one third of the ophthalmologists and optometrists in Oregon and Washington . It contained questions pertaining to practitioner attitudes toward their educational backgrounds in visual training. Questions dealing with some of the controversial issues in visual training\u27s role in strabismus and amblyopia therapy were also included. Lastly, profile information and data concerning the practice in general was gathered from each survey recipient. The respondent population was divided into groups by profession and extent of VT offered. The different groups responses were then tabulated and statistically compared within and between professions

Introgressive Hybridization and the Evolution of Lake-Adapted Catostomid Fishes.

Hybridization has been identified as a significant factor in the evolution of plants as groups of interbreeding species retain their phenotypic integrity despite gene exchange among forms. Recent studies have identified similar interactions in animals; however, the role of hybridization in the evolution of animals has been contested. Here we examine patterns of gene flow among four species of catostomid fishes from the Klamath and Rogue rivers using molecular and morphological traits. Catostomus rimiculus from the Rogue and Klamath basins represent a monophyletic group for nuclear and morphological traits; however, the Klamath form shares mtDNA lineages with other Klamath Basin species (C. snyderi, Chasmistes brevirostris, Deltistes luxatus). Within other Klamath Basin taxa, D. luxatus was largely fixed for alternate nuclear alleles relative to C. rimiculus, while Ch. brevirostris and C. snyderi exhibited a mixture of these alleles. Deltistes luxatus was the only Klamath Basin species that exhibited consistent covariation of nuclear and mitochondrial traits and was the primary source of mismatched mtDNA in Ch. brevirostris and C. snyderi, suggesting asymmetrical introgression into the latter species. In Upper Klamath Lake, D. luxatus spawning was more likely to overlap spatially and temporally with C. snyderi and Ch. brevirostris than either of those two with each other. The latter two species could not be distinguished with any molecular markers but were morphologically diagnosable in Upper Klamath Lake, where they were largely spatially and temporally segregated during spawning. We examine parallel evolution and syngameon hypotheses and conclude that observed patterns are most easily explained by introgressive hybridization among Klamath Basin catostomids

Pressure Broadening and Shift of the Cesium D\u3csub\u3e1\u3c/sub\u3e Transition by the Noble Gases and N\u3csub\u3e2\u3c/sub\u3e, H\u3csub\u3e2\u3c/sub\u3e, HD, D\u3csub\u3e2\u3c/sub\u3e, CH\u3csub\u3e4\u3c/sub\u3e, C\u3csub\u3e2\u3c/sub\u3eH\u3csub\u3e6\u3c/sub\u3e, CF\u3csub\u3e4\u3c/sub\u3e, and \u3csup\u3e3\u3c/sup\u3eHe

The pressure broadening and shift rates for the cesium D1 (62P1/2 ← 6 2S1/2) transition with the noble gases and N2, H2, HD, D2, CH4, C2H6, CF4, and 3He were obtained for pressures less than 300 torr at temperatures under 65 °C by means of laser absorption spectroscopy. The collisional broadening rate, γL, for He, Ne, Ar, Kr, Xe, N2, H2, HD, D2, CH4, C2H6, CF4, and 3He are 24.13, 10.85, 18.31, 17.82, 19.74, 16.64, 20.81, 20.06, 18.04, 29.00, 26.70, 18.84, and 26.00 MHz/torr, respectively. The corresponding pressure-induced shift rates, δ, are 4.24, −1.60, −6.47, −5.46, −6.43, −7.76, 1.11, 0.47, 0.00, −9.28, −8.54, −6.06, and 6.01 MHz/torr. These rates have then been utilized to calculate Lennard-Jones potential coefficients to quantify the interatomic potential surfaces. The broadening cross section has also been shown to correlate with the polarizability of the collision partner

The Effects of Team Flow on Performance: A Video Game Experiment

Research on effective team work has traditionally explained team performance as a result of team cohesion and goal commitment. Team cohesion was originally defined as the general level of attraction the team members had to all others in their group. This social relations-based concept of team cohesion is generally a strong indicator of team performance. However, more recent research has stressed the importance of incorporating the team members’ mutual level of commitment to the team task as another sub-dimension of cohesion. When including task commitment, team cohesion is a somewhat weaker predictor of team performance (Beal et al., 2003). To better conceptualize the role of the task engagement and to explain team performance, we incorporate a variable more relevant to the characteristics of a team task: team flow. The concept of “flow” has been well researched and theorized at the individual level. However, in an experiment based on collaborative video gaming, we demonstrate that not only can flow be extended to the team level to better explain performance, but that teams can quickly generate a psychological flow state from low cost treatments like collaborative video gaming which can also be effectively transferred into subsequent work tasks

Team Video Gaming for Team Building: Effects on Team Performance

Teams rapidly form and dissolve in organizations to solve specific problems that require diverse skills and experience. For example, in the information systems context, cross-functional and project-based teams that comprise a mix of personnel who temporarily work away from their usual functional groups (best perform agile software development (Barlow et al., 2011; Keith, Demirkan, & Goul, 2013). These newly formed work teams need to become productive as quickly as possible. Team video gaming (TVG) has emerged as a potential team-building activity. When new teammates play a collaborative video game, they engage in cooperative and challenging goals while they enjoy the games. Although research has shown that video games can promote learning and recreation, it has not investigated the effects of commercial video games on subsequent work-team performance. Better understanding this issue will provide insights into how to rapidly develop cohesion among newly formed work teams and, thus, lead to greater team performance. We examined this issue through a laboratory experiment. We found that teams in the TVG treatment demonstrated a 20 percent productivity improvement in subsequent tasks (in our case, a team-based geocaching scavenger hunt) over teams that participated in traditional team-building activities
