Deception in Group Contexts

Unethical behavior is often viewed as an individual-level phenomenon. However, group membership can influence individuals’ choices to behave ethically or not (Messick, 2006). This chapter discusses whether and when groups will be more likely than individuals to use deception. We focus on three areas of research. The first involves comparing individuals and groups in mixed-motive situations, and the discontinuity between individual and group responses to economic games: individuals tend to cooperate while groups tend to compete (Wildschut, Pinter, Veva, Insko, & Schopler, 2003). In terms of deception, this is interesting as both individuals and groups initially cooperate. We discuss explanations for the effect and their relation to why groups use deception. Second, we focus on general differences between individual and group deception. Deception can be beneficial when negotiating, and groups tend to use deception to their benefit (Cohen, Gunia, Kim-Jun, & Murnighan, 2009; Sutter, 2009). We discuss explanations for these effects and provide a framework for understanding when and why groups use deception

Observations of red-giant variable stars by Aboriginal Australians

Aboriginal Australians carefully observe the properties and positions of stars, including both overt and subtle changes in their brightness, for subsistence and social application. These observations are encoded in oral tradition. I examine two Aboriginal oral traditions from South Australia that describe the periodic changing brightness in three pulsating, red-giant variable stars: Betelgeuse (Alpha Orionis), Aldebaran (Alpha Tauri), and Antares (Alpha Scorpii). The Australian Aboriginal accounts stand as the only known descriptions of pulsating variable stars in any Indigenous oral tradition in the world. Researchers examining these oral traditions over the last century, including anthropologists and astronomers, missed the description of these stars as being variable in nature as the ethnographic record contained several misidentifications of stars and celestial objects. Arguably, ethnographers working on Indigenous Knowledge Systems should have academic training in both the natural and social sciences.Comment: The Australian Journal of Anthropology (2018

Citizen perceptions and values associated with ecosystem services from European grassland landscapes

European permanent grasslands are multifunctional landscapes that deliver an important mix of ecosystem services. The effectiveness of future policies linked to landscape and agricultural practices requires consideration of citizen perceptions of, and priorities for, benefits (e.g. ecosystem services) demanded from permanent grasslands. This exploratory research aimed to expand understanding of citizens' perceptions and socio-cultural valuation of grassland landscapes, ecosystem service provision and management across Europe in order to inform future research. Fifteen focus groups with residents of rural areas, urban areas, and young adults from rural areas (aged 18-26) (N = 104), were conducted across five European countries (Spain, Sweden, UK, Switzerland and the Czech Republic) between 2020 and 2021. Overall, participants perceived grassland landscapes positively, describing connection to the landscape through experience, emotions, environmental characteristics, activity, access, and cultural identity. Prioritisation of ecosystem services from grassland varied between countries, influenced by grassland system diversity, and complex socio-cultural and socio-economic differences. Rural dwellers, including rural youth, perceived more benefits from grasslands than urban dwellers. Perceptions of problems were related to reduction, degradation and abandonment of grassland, and varied between urban and rural dwellers. Consumer education about the value of grasslands was perceived as vital in ensuring sustainable management and use of these landscapes. Citizens across different countries shared farming ideals relating to farming for biodiversity. These findings can help ensure that policies surrounding landscape and agricultural practices align with societal perspectives and priorities to effectively deliver multifunctional, valued, sustainable grassland systems

Head up ; an interdisciplinary, participatory and co-design process informing the development of a novel neck support for people living with progressive neck muscle weakness

This paper presents the Head-Up project that aims to provide innovative head support to help improve posture, relieve pain and aid communication for people living with progressive neck muscle weakness. The initial focus is motor neurone disease. The case study illustrates collaborative, interdisciplinary research and new product development underpinned by participatory design. The study was initiated by a two-day stakeholder workshop followed by early proof-of-concept modeling and patient need evidence building. The work subsequently led to a successful NIHR i4i application funding a 24-month iterative design process, patenting, CE marking and clinical evaluation. The evaluation has informed amendments to the proposed design we refer to here as the Sheffield Support Snood (SSS). The outcome positively demonstrates use and performance improvements over current neck orthoses and, the process of multidisciplinary and user engagement has created a sense of ownership by MND participants, who have since acted as advocates for the product.</p

Conversion of sub-tropical native vegetation to introduced conifer forest: Impacts on below-ground and above-ground carbon pools

Land-use change can have a major influence on soil organic carbon (SOC) and above-ground C pools. We assessed a change from native vegetation to introduced Pinus species plantations on C pools using eight paired sites. At each site we determined the impacts on 0–50 cm below-ground (SOC, charcoal C, organic matter C, particulate organic C, humic organic C, resistant organic C) and above-ground (litter, coarse woody debris, standing trees and woody understorey plants) C pools. In an analysis across the different study sites there was no significant difference (P &gt; 0.05) in SOC or above-ground tree C stocks between paired native vegetation and pine plantations, although significant differences did exist at specific sites. SOC (calculated based on an equivalent soil mass basis) was higher in the pine plantations at two sites, higher in the native vegetation at two sites and did not differ for the other four sites. The site to site variation in SOC across the landscape was far greater than the variation observed with a change from native vegetation to introduced Pinus plantation. Differences between sites were not explained by soil type, although tree basal area was positively correlated with 0–50 cm SOC. In fact, in the native vegetation there was a significant linear relationship between above-ground biomass and SOC that explained 88.8% of the variation in the data. Fine litter C (0–25 mm diameter) tended to be higher in the pine forest than in the adjacent native vegetation and was significantly higher in the pine forest at five of the eight paired sites. Total litter C (0–100 mm diameter) increased significantly with plantation age (R2 = 0.64). Carbon stored in understorey woody plants (2.5–10 cm DBH) was higher in the native vegetation than in the adjacent pine forest. Total site C varied greatly across the study area from 58.8 Mg ha−1 at a native heathland site to 497.8 Mg ha−1 at a native eucalypt forest site. Our findings suggest that the effects of change from native vegetation to introduced Pinus sp. forest are highly site-specific and may be positive, negative, or have no influence on various C pools, depending on local site characteristics (e.g. plantation age and type of native vegetation)

Applying Recent Argumentation Methods to Some Ancient Examples of Plausible Reasoning

Plausible (eikotic) reasoning known from ancient Greek (late Academic) skeptical philosophy is shown to be a clear notion that can be analyzed by argu- mentation methods, and that is important for argumentation studies. It is shown how there is a continuous thread running from the Sophists to the skeptical philosopher Carneades, through remarks of Locke and Bentham on the subject, to recent research in artificial intelligence. Eleven characteristics of plausible reasoning are specified by analyzing key examples of it recognized as important in ancient Greek skeptical philosophy using an artificial intelligence model called the Carneades Argumentation System (CAS). By applying CAS to ancient examples it is shown how plausible reasoning is especially useful for gaining a better understanding of evidential reasoning in law, and argued that it can also be applied to everyday argumentation. Our analysis of the snake and rope example of Carneades is also used to point out some ways CAS needs to be extended if it is to more fully model the views of this ancient philosopher on argumentation

The development of a space climatology: 3. Models of the evolution of distributions of space weather variables with timescale

We study how the probability distribution functions of power input to the magnetosphere Pα and of the geomagnetic ap and Dst indices vary with averaging timescale, , between 3 hours and 1 year. From this we develop and present algorithms to empirically model the distributions for a given and a given annual mean value. We show that lognormal distributions work well for ap, but because of the spread of Dst for low activity conditions, the optimum formulation for Dst leads to distributions better described by something like the Weibull formulation. Annual means can be estimated using telescope observations of sunspots and modelling, and so this allows the distributions to be estimated at any given between 3 hour and 1 year for any of the past 400 years, which is another important step towards a useful space weather climatology. The algorithms apply to the core of the distributions and can be used to predict the occurrence rate of “large” events (in the top 5% of activity levels): they may contain some, albeit limited, information relevant to characterizing the much rarer “superstorm” events with extreme value statistics. The algorithm for the Dst index is the more complex one because, unlike ap, Dst can take on either sign and future improvements to it are suggested

Australian Aboriginal Ethnometeorology and Seasonal Calendars

This paper uses a cultural anthropological approach to investigate an indigenous Australian perspective on atmospheric phenomena and seasons, using data gained from historical records and ethnographic fieldwork. Aboriginal people believe that the forces driving the weather are derived from Creation Ancestors and spirits, asserting that short term changes are produced through ritual. By recognizing signals such as wind direction, rainfall, temperature change, celestial movements, animal behaviour and the flowering of plants, Aboriginal people are able to divide the year into seasons. Indigenous calendars vary widely across Australia and reflect annual changes within Aboriginal lifestyles

Visual arguments in film

Nuestro objetivo es señalar algunas diferencias entre los argumentos verbales y visuales, y promover la perspectiva retórica de la argumentación, yendo más allá de la relevancia de la lógica y de la pragmática. En nuestra opinión, si ha de ser racional y aceptable como argumentación (visual), un film debe dirigirse a espectadores que tienen creencias informadas sobre el tema visto en la pantalla y sobre las limitaciones y las convenciones del medio. En nuestras reflexiones, aplicamos el análisis retórico al cine como un acto simbólico, humano y comunicativo que a veces puede entenderse como un argumento trazado visualmente. Como mezcla de estímulos visuales, auditivos y verbales, el film exige una interpretación y una (re)construcción activas y complejas. Nuestra sugerencia es concentrarse en cinco elementos diferentes, pero relacionados entre sí. La reconstrucción y la evaluación del argumento visual se basarán en esos elementos, y todo el proceso constituirá una argumentación visual.Our aim is to point out some differences between verbal and visual arguments, promoting the rhetorical perspective of argumentation beyond the relevance of logic and pragmatics. In our view, if it is to be rational and successful, film as (visual) argumentation must be addressed to spectators who hold informed beliefs about the theme watched on the screen and the medium’s constraints and conventions. In our reflections to follow, we apply rhetorical analysis to film as a symbolic, human, and communicative act that may sometimes be understood as a visually laid out argument. As a mixture of visual, auditory, and verbal stimuli, film demands active and complex interpretation and (re)construction. Our suggestion is to focus on five different but interrelated elements. The reconstruction and evaluation of the visual argument will be based on those elements, and the whole process will be one of visual argumentation
