Facebook surveillance of former romantic partners: Associations with post-breakup recovery and personal growth
Copyright @ 2012 Mary Ann Liebert, Inc.This article has been made available through the Brunel Open Access Publishing Fund.Previous research has found that continuing offline contact with an ex-romantic partner following a breakup may disrupt emotional recovery. The present study examined whether continuing online contact with an ex-partner through remaining Facebook friends and/or engaging in surveillance of the ex-partner's Facebook page inhibited postbreakup adjustment and growth above and beyond offline contact. Analysis of the data provided by 464 participants revealed that Facebook surveillance was associated with greater current distress over the breakup, more negative feelings, sexual desire, and longing for the ex-partner, and lower personal growth. Participants who remained Facebook friends with the ex-partner, relative to those who did not remain Facebook friends, reported less negative feelings, sexual desire, and longing for the former partner, but lower personal growth. All of these results emerged after controlling for offline contact, personality traits, and characteristics of the former relationship and breakup that tend to predict postbreakup adjustment. Overall, these findings suggest that exposure to an ex-partner through Facebook may obstruct the process of healing and moving on from a past relationship
Families of Linear Efficiency Programs based on Debreu's Loss Function
Gerard Debreu introduced a well known radial efficiency measure which he called a “coefficient of resource utilization.†He derived this scalar from a much less well known “dead loss†function that characterizes the monetary value sacrificed to inefficiency, and which is to be minimized subject to a normalization condition. We use Debreu’s loss function, together with a variety of normalization conditions, to generate several popular families of linear efficiency programs. Our methodology also can be employed to generate entirely new families of linear efficiency programs.
\u27I am not writing anything just now\u27: A Letter from Walter Scott to Sarah Smith, February 13, 1814
Describes and reproduces a letter written by Sir Walter Scott to the actress Sarah Smith (later Mrs Bartley), in February 1814, in which he tells her shortly before the anonymous publication of his novel Waverley that I am not writing anything just now ; discusses Scott\u27s interest in Smith\u27s career, his brief comments on the dramatist Joanna Baillie, and the extent to which Smith was in his confidence about his writing
Physiotherapy students\u27 perceptions and experiences of clinical prediction rules
Objectives: Clinical reasoning can be difficult to teach to pre-professional physiotherapy students due to their lack of clinical experience. It may be that tools such as clinical prediction rules (CPRs) could aid the process, but there has been little investigation into their use in physiotherapy clinical education. This study aimed to determine the perceptions and experiences of physiotherapy students regarding CPRs, and whether they are learning about CPRs on clinical placement.
Design: Cross-sectional survey using a paper-based questionnaire.
Participants: Final year pre-professional physiotherapy students (n=371, response rate 77%) from five universities across five states of Australia.
Results: Sixty percent of respondents had not heard of CPRs, and a further 19% had not clinically used CPRs. Only 21% reported using CPRs, and of these nearly three-quarters were rarely, if ever, learning about CPRs in the clinical setting. However most of those who used CPRs (78%) believed CPRs assisted in the development of clinical reasoning skills and none (0%) was opposed to the teaching of CPRs to students. The CPRs most commonly recognised and used by students were those for determining the need for an X-ray following injuries to the ankle and foot (67%), and for identifying deep venous thrombosis (63%).
Conclusions: The large majority of students in this sample knew little, if anything, about CPRs and few had learned about, experienced or practiced them on clinical placement. However, students who were aware of CPRs found them helpful for their clinical reasoning and were in favour of learning more about them
Hubble space telescope STIS spectroscopy of the peculiar nova-like variables BK Lyn, V751 Cygni, and V380 Oph
We obtained Hubble STIS spectra of three nova-like variables: V751 Cygni, V380 Oph, and—the only confirmed nova-like variable known to be below the period gap—BK Lyn. In all three systems, the spectra were taken during high optical brightness state, and a luminous accretion disk dominates their far-ultraviolet (FUV) light. We assessed a lower limit of the distances by applying the infrared photometric method of Knigge. Within the limitations imposed by the poorly known system parameters (such as the inclination, white dwarf mass, and the applicability of steady state accretion disks) we obtained satisfactory fits to BK Lyn using optically thick accretion disk models with an accretion rate of for a white dwarf mass of Mwd = 1.2M and for Mwd = 0.4M. However, for the VY Scl-type nova-like variable V751 Cygni and for the SW Sex star V380 Oph, we are unable to obtain satisfactory synthetic spectral fits to the high state FUV spectra using optically thick steady state accretion disk models. The lack of FUV spectra information down to the Lyman limit hinders the extraction of information about the accreting white dwarf during the high states of these nova-like systems

Public understanding towards sustainable clothing and the supply chain
The evident contradiction between fashion culture and sustainability raises critical issues for the clothing industry and public understanding will be important if strategies to help the industry evolve in a more sustainable direction are to succeed. This paper reports on the early stages of research into a more sustainable supply chain development model. The research aims to discover the problems affecting sustainability that currently exist in the fashion supply chain by considering different points of view from representatives of consumers and clothing industry experts. Areas to be addressed include green manufacturing, organic garments, the reusing or recycling of used and unwanted clothes, and the market for second hand clothes. This paper utilises findings from a consumer questionnaire and interviews with consumers and industry representatives to explore public awareness and understanding of sustainable clothing and recent industry initiatives. The consumer research confirmed that while some consumers are informed and aware of the issues, others show little interest in sustainability aspects of fashion. The industry research indicated the potential for promoting sustainability in the fashion supply chain, but found that little communication has been made to consumers. Further research will be undertaken to explore how the fashion industry can develop a sustainable business model in the light of public behaviour and market conditions

Capacity investigation of brine-bearing sands of the Frio Formation for geologic sequestration of CO2
The capacity of fluvial brine-bearing formations to sequester CO2 is investigated using numerical simulations of CO2 injection and storage. Capacity is defined as the volume fraction of the subsurface available for CO2 storage and is conceptualized as a product of factors that account for two-phase flow and transport processes, formation geometry, formation heterogeneity, and formation porosity. The space and time domains used to define capacity must be chosen with care to obtain meaningful results, especially when comparing different authors’ work. Physical factors that impact capacity include permeability anisotropy and relative permeability to CO2, brine/CO2 density and viscosity ratios, the shape of the trapping structure, formation porosity and the presence of low permeability layering.National Energy Technology LaboratoryBureau of Economic Geolog
Twenty-one centimeter tomography with foregrounds
Twenty-one centimeter tomography is emerging as a powerful tool to explore
the end of the cosmic dark ages and the reionization epoch, but it will only be
as good as our ability to accurately model and remove astrophysical foreground
contamination. Previous treatments of this problem have focused on the angular
structure of the signal and foregrounds and what can be achieved with limited
spectral resolution (bandwidths in the 1 MHz range). In this paper we introduce
and evaluate a ``blind'' method to extract the multifrequency 21cm signal by
taking advantage of the smooth frequency structure of the Galactic and
extragalactic foregrounds. We find that 21 cm tomography is typically limited
by foregrounds on scales Mpc and limited by noise on scales Mpc, provided that the experimental bandwidth can be made substantially
smaller than 0.1 MHz. Our results show that this approach is quite promising
even for scenarios with rather extreme contamination from point sources and
diffuse Galactic emission, which bodes well for upcoming experiments such as
LOFAR, MWA, PAST, and SKA.Comment: 10 pages, 6 figures. Revised version including various cases with

International Advisees\u27 Perspectives on the Advising Relationship in Counseling Psychology Doctoral Programs
Ten international students in U.S.-based counseling psychology doctoral programs were interviewed regarding their experiences as doctoral students, especially their advising relationship. Data were analyzed using consensual qualitative research (CQR). Participants reported more challenges than benefits of being international students, and more often described their doctoral programs as not culturally receptive than receptive to international students. Despite this assessment of the overall doctoral program, they described their own advising relationships as predominantly positive. Many international students discussed with their advisor their difficulties adjusting to a new environment and being away from home, and identified unique personal and professional needs as international students. Participants recommended that international students openly communicate with and seek a good relationship with their advisors, and also recommended that advisors of international students seek to understand and attend to international students\u27 culture and the challenges of being an international student. Implications for training and research are addressed
