EVALUATING SOCIAL EXCLUSION: THE INTERACTION BETWEEN GROUP GOALS AND TARGET CHARACTERISTICS

Past work has revealed that adolescents utilize a variety of justifications to support exclusion and inclusion judgments. Group functioning justifications (e.g., "She will ruin the group/make the group work well") are one frequently cited class of considerations. This type of justification is suggestive of an attempt by the adolescent to coordinate group concerns with what the target will likely bring to the group. The above account of group functioning considerations, however, has yet to be formally tested. In this report, both target characteristics (e.g., aggression, shyness, gender) as well as group goals (competitive, noncompetitive) are manipulated in a soccer context to assess the extent to which exclusion judgments rely on the perception of target-group fit. We demonstrate evidence consistent with a target-group fit account of exclusion judgments. Implications and future directions are considered

Case Study Summary: Johnson & Johnson and Macy\u27s Inc.

This thesis, over a one-year period, covers conclusions derived from research on two different companies: Johnson & Johnson and Macy’s Inc. Through a two-semester course taken within the scope of the honors college alongside Dr. Victoria Dickinson, I, alongside my respective group members for each company, were able to compile a thorough analysis of risks and business strategies the two corporations could identify and implement to manage present and future complications. This analysis followed standard conventions of the accounting profession, as our research was focused on identifying risks and strategies affiliated with audit, tax, and advisory services, modeling how professional life in accounting would be when attempting to grasp a full understanding of a certain company. In addition, the research extended to contemporary issues as well, as my group members and I observed how current economic and political trends would impact each company. The rise of Environmental, Social, and Corporate Governance (ESG), inflation fears, COVID-19 impacts, and political turmoil domestically and internationally were all factors considered when researching the respective corporations. From this, we then put forth solutions for each company to improve their relative position. Whether it be to accelerate taxable income to avoid higher tax rates in the future or taking advantage of certain tax credits available to the company, our group compiled these findings over the scope of our research and presented them to accounting professionals for criticism and cross-analysis. Below you will find, in detail, the totality of our formal written research completed for my thesis. This first half of it includes the work for Johnson and Johnson, and the second half includes Macy’s Inc

Acoustic measurement of lubricant-film thickness distribution in ball bearings

An oil-film thickness monitoring system capable of providing an early warning of lubrication failure in rolling element bearings has been developed. The system is used to measure the lubricant-film thickness in a conventional deep groove ball bearing (shaft diameter 80 mm, ball diameter 12.7 mm). The measurement system comprises a 50 MHz broadband ultrasonic focused transducer mounted on the static outer raceway of the bearing. Typically the lubricant-films in rolling element bearings are between 0.1-1.0 μm in thickness and so are significantly smaller than the ultrasonic wavelength. A quasistatic spring model is used to calculate oil-film thickness from the measured reflection coefficient data. An accurate triggering system has been developed to enable multiple reflection coefficient measurements to be made as the contact ellipse sweeps over the measurement location. Experiments are described in which the loading conditions and rotational speed are varied. Lubricant-film thickness distributions measured ultrasonically are described and are shown to agree well with the predictions from classical elastohydrodynamic (EHD) lubrication theory, particularly at high radial loads and low rotary speeds. A range of parameters affecting the performance of the measurement are discussed and the limits of operation of the measurement technique defined. © 2006 Acoustical Society of America

Underreamer mechanics

In the oil and gas industry, an underreamer is a tool used to extend and enlarge the diameter of a previously-drilled bore. The problem proposed to the Study Group is to obtain appropriate mathematical models of underreamer dynamics, in forms that will lead to feasible computation. The modes of dynamics of interest are torsional, lateral and axial. This report describes some initial models, two of which are developed in more detail: one for the propagation of torsional waves along the drill string and their reflection from contact points with the well bore; and one for the dynamic coupling between the underreamer and the drill bit during drilling

Radicalisation of Young Adults in the Balkan States: Counter-Measures, Healthcare Provision, and Community Involvement

Decreasing the rise of extremism remains a priority for governments worldwide.  Motives behind joining an extremist organisation are complex and often unique to the individual, making prevention strategies difficult to design and implement.  This article explores several facets of this complex problem, particularly in relation to young adults, including links between extremism, criminality and incarceration, mental health, socioeconomic status and the rise of radicalisation ‘hotspots’ in Muslim majority states in the Western Balkans, where lack of government leadership allows extremist organisations to flourish.  Potential counter radicalisation measures are also discussed in various contexts, including healthcare systems, the community, internationally and within the Balkan region

Functional green roofs: Importance of plant choice in maximising summertime environmental cooling and substrate insulation potential

Green roof plants can reduce local air temperatures and heat load to a building in the summer, improving thermal comfort of residents. Little is known, however, about how different plants compare in their potential to provide these two ecosystem services. Consequently, this study investigated whether some plants can offer more potential summertime environmental cooling and substrate insulation than others. Over two summers (2012/2013), canopies of two succulent and four broad-leaved plant genotypes, with contrasting plant traits, were monitored alongside bare substrate in Reading, UK. Plants were studied outdoors within small plots (1.5 × 1.5 × 0.1 m). Continuous monitoring took place during warm days and nights and included variables (leaf surface temperatures) and fluxes (long-wave radiation, sensible heat flux and transpiration) that are indicative of cooling potential. The strength of substrate insulation was estimated by comparing the ground heat flux below the canopies to that of the bare substrate. Plant traits (leaf colour or thickness), structural parameters (height and leaf area index, LAI), radiative properties (albedo and emissivity), and stomatal conductance were also measured to help explain the differences in cooling potential among the species. Non-succulent canopies, in particular light-coloured ones, with high leaf stomatal conductance and high LAI provided maximum potential for substrate insulation and environmental cooling in hot periods, particularly compared to bare substrate and thick-leaved succulents. These results suggest that succulent plants are not best suited to provide significant summertime environmental cooling and substrate insulation and that others (e.g. Salvia and Stachys) might be preferable where the delivery of these benefits is a priority. Our findings highlight that, in addition to survival, aesthetics and cost, the plants’ ability to deliver a range of ecosystem services should be considered in the plant selection/green roof planning process

The Mechanism behind Erosive Bursts in Porous Media

Erosion and deposition during flow through porous media can lead to large erosive bursts that manifest as jumps in permeability and pressure loss. Here we reveal that the cause of these bursts is the re-opening of clogged pores when the pressure difference between two opposite sites of the pore surpasses a certain threshold. We perform numerical simulations of flow through porous media and compare our predictions to experimental results, recovering with excellent agreement shape and power-law distribution of pressure loss jumps, and the behavior of the permeability jumps as function of particle concentration. Furthermore, we find that erosive bursts only occur for pressure gradient thresholds within the range of two critical values, independent on how the flow is driven. Our findings provide a better understanding of sudden sand production in oil wells and breakthrough in filtration.Comment: 7 pages, 8 figure
