Tagger's delight? Disclosure and liking in Facebook: the effects of sharing photographs amongst multiple known social circles
The present work identifies the relationship between sharing photographs with different depictions in Facebook on relationship quality, which varies depending on the type of target sharing the photographs. With over 1 billion active users, disclosure on Facebook is frequent, considered a norm of online interaction, and actively encouraged by site providers. The extant academic literature identifies Facebook as an effective tool to connect with known and unknown others, and identifies the differences in sharing behaviour when users are aware of their audience. Operating within a lowest common denominator approach to disclosure on Facebook, the present work identifies the potential consequences to personal relationships when sharing day-to-day information. Results found from a sample of 508 Facebook users suggests individuals should actively adjust their privacy settings to ensure that even amongst flattened information â i.e. that deemed appropriate for release to all target types â disclosure does not harm current and potential relationships. Implications for, users, academic theory and disclosure practice are discussed

Magnificent Distance: Five Site-Specific Installations Washington DC 2012
5x5, Washington DCâs inaugural public art festival, was conceived as a flagship biennial in which five curators would each be invited to curate new site-specific artworks by five artists â leading to the simultaneous installation of twenty-five artworks across Washington DC.
The primary research question explored in the curation of the five Magnificent Distance artworks was the slippage between the symbolic DC of the worldwide public imagination and the âdomesticâ, human DC with its complex histories and communities. Many of the exhibition sites, selected as part of my curatorial role, were at the interstices of these two DC realities â at the meeting point between federal and community environments, in locations undergoing transformation from one use to another, and at points where differing scales of architecture meet
Can you create? Visualising and modelling real-world mathematics with technologies in STEAM educational settings
peer reviewedIn the past three decades, and especially accelerated during the Covid-19 pandemic, technology-assisted learning and teaching, and particularly in our case dynamic mathematics software in science-technology-engineering-arts-mathematics (STEAM) settings are becoming increasingly important. More recently, the development of more advanced mathematics-related technologies such as augmented reality, computer-aided design software, 3D printing, and global positioning system-enabled visualisations and modulations of mathematical concepts and the development of different behaviours in learning and teaching. These advanced technologies could enable students to more easily become creators, develop simulations, and utilise multiple representations of real-world or abstract objects by applying their mathematical and modelling skills. In addition, through such approaches, mathematical modelling and visualisations facilitated crossing subject boundaries in Science Technology Engineering and Mathematics (STEM) and more recently STEAM fields. Consequently, there is an increased amount of research connecting studentsâ visualisations and modelling of their real-world environments and working on real-world problems with these technologies. In this paper, we reviewed promising research within the past two years on the uses of advanced technologies in mathematics, and in a broad sense STEAM education, circling around the question âCan you create?â and how such novel approaches could impact behaviours of students and teachers in the current educational circumstances
Understanding the psychological process of avoidance-based self-regulation on Facebook
In relation to social network sites, prior research has evidenced behaviors (e.g., censoring) enacted by individuals used to avoid projecting an undesired image to their online audiences. However, no work directly examines the psychological process underpinning such behavior. Drawing upon the theory of self-focused attention and related literature, a model is proposed to fill this research gap. Two studies examine the process whereby public self-awareness (stimulated by engaging with Facebook) leads to a self-comparison with audience expectations and, if discrepant, an increase in social anxiety, which results in the intention to perform avoidance-based self-regulation. By finding support for this process, this research contributes an extended understanding of the psychological factors leading to avoidance-based regulation when online selves are subject to surveillance
A Feasibility Study of an Intervention for Structured Preparation before Detoxification in Alcohol Dependence: the SPADe trial protocol
Background: Alcohol-related harm is currently estimated to cost the National Health Service (NHS) in England ÂŁ3.5bn a year. Of the estimated 1.6 million people with some degree of alcohol dependence, some 600,000 are believed to be moderately or severely dependent and may benefit from intensive treatment. Outcomes from medically assisted withdrawal, also referred to as detoxification, are often poor, with poor engagement in relapse prevention interventions and subsequent high relapse rates. Detoxification is costly both financially and to the individual. It has been found that people who experience multiple detoxifications show more emotional and cognitive impairments. These changes may confer upon them the inability to resolve conflict and increased sensitivity to stress thus contributing to increased vulnerability risk of relapse. The study aims to test the feasibility of using a group intervention aiming to prepare participants for long term abstinence before, rather than after, they have medically assisted detoxification. The current study will establish key parameters that influence trial design such as recruitment, compliance with the intervention, retention, and sensitivity of alternative outcome measures, in preparation for a future Randomised Controlled Trial (RCT). This paper presents the protocol of the feasibility study. Methods: The study corresponds to Phase 2 of the Medical Research Council (MRC) complex interventions guidelines which cover the development and feasibility testing of an intervention. The work is in three stages. The development, adaptation, and implementation of the Structured Preparation before Alcohol Detoxification (SPADe) intervention (stage 1), a randomised feasibility study with economic evaluation (stage 2) and a qualitative study (stage 3). Fifty participants will be recruited from two community alcohol treatment services in England. Participants will be randomised in two arms: the treatment as usual arm (TAU), which includes planned medically assisted detoxification and aftercare and the intervention arm in which participants will receive structured group preparation before detoxification in addition to TAU. The main outcomes are duration of continuous abstinence with no incidents of lapse or relapse, percentage of days abstinent and time to relapse. Discussion: The socioeconomic harms associated with alcohol have been well documented yet existing treatment options have not been able to reduce high relapse rates. This study will build on existing naturalistic studies underpinned by psychological interventions offered early and before detoxification from alcohol, which aim to reverse automatised habitual behaviours and thus may help us to understand how better to support people to remain abstinent and improve post detoxification outcomes.

Local Moment Formation in the Periodic Anderson Model with Superconducting Correlations
We study local moment formation in the presence of superconducting
correlations among the f-electrons in the periodic Anderson model. Local
moments form if the Coulomb interaction U>U_cr. We find that U_cr is
considerably stronger in the presence of superconducting correlations than in
the non-superconducting system. Our study is done for various values of the
f-level energy and electronic density. The smallest critical U_cr values occur
for the case where the number of f- electrons per site is equal to one. In the
presence of d-wave superconducting correlations we find that local moment
formation presents a quantum phase transition as function of pressure. This
quantum phase transition separates a region where local moments and d-wave
superconductivity coexist from another region characterized by a
superconducting ground state with no local moments. We discuss the possible
relevance of these results to experimental studies of the competition between
magnetic order and superconductivity in CeCu_2Si_2.Comment: 4 pages. accepted for publication in Phys. Rev.
The terrestrial carbon budget of South and Southeast Asia
Accomplishing the objective of the current climate policies will require establishing carbon budget and flux estimates in each region and county of the globe by comparing and reconciling multiple estimates including the observations and the results of top-down atmospheric carbon dioxide (CO2) inversions and bottom-up dynamic global vegetation models. With this in view, this study synthesizes the carbon source/sink due to net ecosystem productivity (NEP), land cover land use change (ELUC), fires and fossil burning (EFIRE) for the South Asia (SA), Southeast Asia (SEA) and South and Southeast Asia (SSEA=SA+SEA) and each country in these regions using the multiple top-down and bottom-up modeling results. The terrestrial net biome productivity (NBP=NEP-ELUC-EFIRE) calculated based on bottom-up models in combination with EFIRE based on GFED4s data show net carbon sinks of 217±147, 10±55, and 227±279 TgC yr?1 for SA, SEA, and SSEA. The top-down models estimated NBP net carbon sinks were 20±170, 4±90 and 24±180 TgC yr?1. In comparison, regional emissions from the combustion of fossil fuels were 495, 275, and 770 TgC yr?1, which are many times higher than the NBP sink estimates, suggesting that the contribution of the fossil fuel emissions to the carbon budget of SSEA results in a significant net carbon source during the 2000s. When considering both NBP and fossil fuel emissions for the individual countries within the regions, Bhutan and Laos were net carbon sinks and rest of the countries were net carbon source during the 2000s. The relative contributions of each of the fluxes (NBP, NEP, ELUC, and EFIRE, fossil fuel emissions) to a nationâs net carbon flux varied greatly from country to country, suggesting a heterogeneous dominant carbon fluxes on the country-level throughout SSEA
