A comparative study of the dominant character strengths of mental health and business graduate students

This exploratory study used the Brief Strengths Survey self-report instrument (Peterson & Park, 2008), based on the Values in Action (VIA) Inventory of Strengths (Seligman & Peterson, 2004), to determine the dominant character strengths of graduate mental health and social work students ( n = 56) as compared to those of MBA students (n = 65) in order to explore the relationship between personality characteristics and career choice. A gender analysis was conducted in order to determine whether dominant character strengths were also related to gender rather than discipline alone. Mental health students had higher scores on the strengths of Kindness/Generosity, Playfulness/Humor, Social Skills/Social Intelligence, Appreciation of Beauty/Awe, Religiousness/Spirituality and Love/Attachment, and MBA student had higher scores on Perseverance/Persistence/Industriousness. Among mental health students, there were no significant differences on dominant character strengths between males and females. On the strengths of Appreciation of Beauty/Awe and Gratitude/Thankfulness, females as a group, regardless of discipline, had higher scores than males of either discipline

If you build it will they come? The boom in purpose-built student accommodation in central Liverpool: Destudentification, studentification and the future of the city

The wave of UK higher education expansion and the commodification of the student experience have reshaped many towns and cities not least in the development of large swathes of private purpose-built student accommodation. A growing body of research has explored the role of purpose-built student accommodation in the processes of studentification and destudentification of neighbourhoods. This study explores the huge and rapid development of purpose-built student accommodation in Liverpool and, for the first time, raises questions not just about its impacts but about its sustainability. The model upon which many of Liverpool’s purpose-built student accommodation projects are based generates hidden risks and carries a momentum that neglects wider market conditions. We conclude that there will be a disorderly end to Liverpool’s purpose-built student accommodation boom and consider the likely implications for a range of stakeholders

Information and Communication Technology, Well-being, and Ethnicity

The relationship between use of information and communication technologies (ICTs) and well-being is an increasingly debated public health issue. Currently, there is limited understanding of how the ethnic digital divide influences this association. Thus, this study assessed how ethnicity has historically moderated relations between ICT (mobile phone, computer, TV) uptake, and several well-being indicators; (a) long-term health (chronic illness), (b) cigarette smoking, and (c) self-perceptions of personal health. Archived data from a UK Office for National Statistics household survey 2007-2011 (97,697 participant records) was analysed, controlling for multiple socio-demographic confounders. Mobile phone dependence was associated with poorer health perceptions in Caucasian women, but more favourable appraisals in ethnic minority females (OR = 0.51). Furthermore, mobile phone uptake was more strongly related to increased behavioural risk (cigarette smoking) in Caucasian men compared with ethnic minority males (OR = 1.68). Ethnicity did not influence relations between ICT uptake and long-term health. Overall, ethnicity was implicated in relations between mobile phone use and well-being indicators: unfavourable associations occurred primarily in Caucasians

Structural model of a complex between the heterotrimeric G protein, Gsα, and tubulin

AbstractA number of studies have demonstrated interplay between the cytoskeleton and G protein signaling. Many of these studies have determined a specific interaction between tubulin, the building block of microtubules, and G proteins. The α subunits of some heterotrimeric G proteins, including Gsα, have been shown to interact strongly with tubulin. Binding of Gα to tubulin results in increased dynamicity of microtubules due to activation of GTPase of tubulin. Tubulin also activates Gsα via a direct transfer of GTP between these molecules. Structural insight into the interaction between tubulin and Gsα was required, and was determined, in this report, through biochemical and molecular docking techniques. Solid phase peptide arrays suggested that a portion of the amino terminus, α2–β4 (the region between switch II and switch III) and α3–β5 (just distal to the switch III region) domains of Gsα are important for interaction with tubulin. Molecular docking studies revealed the best-fit models based on the biochemical data, showing an interface between the two molecules that includes the adenylyl cyclase/Gβγ interaction regions of Gsα and the exchangeable nucleotide-binding site of tubulin. These structural models explain the ability of tubulin to facilitate GTP exchange on Gα and the ability of Gα to activate tubulin GTPase

Measurement of the total neutron cross section on argon in the 20 to 70 keV energy range

The cross section for neutron interactions on argon is an important design and operational parameter for a number of neutrino, dark matter, and neutrinoless double beta decay experiments which use liquid argon as a detection or shielding medium. There is a discrepancy between the evaluated total cross section in the $20$ to $70~\rm$\,keV neutron kinetic energy region given in the ENDF database and a single measurement conducted by an experiment with a thin target (0.2 atoms/barn) optimized for higher cross sections. This gives rise to significant uncertainty in the interaction length of neutrons in liquid argon. This discrepancy is now resolved by new results presented here from the Argon Resonance Transport Interaction Experiment (ARTIE), a thick target experiment (3.3 atoms/barn) optimized for the small cross sections in this energy region.Comment: 6 pages, 4 figures.

Inclusive Search for Anomalous Production of High-pT Like-Sign Lepton Pairs in Proton-Antiproton Collisions at sqrt{s}=1.8 TeV

We report on a search for anomalous production of events with at least two charged, isolated, like-sign leptons with pT > 11 GeV/c using a 107 pb^-1 sample of 1.8 TeV ppbar collisions collected by the CDF detector. We define a signal region containing low background from Standard Model processes. To avoid bias, we fix the final cuts before examining the event yield in the signal region using control regions to test the Monte Carlo predictions. We observe no events in the signal region, consistent with an expectation of 0.63^(+0.84)_(-0.07) events. We present 95% confidence level limits on new physics processes in both a signature-based context as well as within a representative minimal supergravity (tanbeta = 3) model.Comment: 15 pages, 4 figures.

Simultaneous measurement of the ratio B(t->Wb)/B(t->Wq) and the top quark pair production cross section with the D0 detector at sqrt(s)=1.96 TeV

We present the first simultaneous measurement of the ratio of branching fractions, R=B(t->Wb)/B(t->Wq), with q being a d, s, or b quark, and the top quark pair production cross section sigma_ttbar in the lepton plus jets channel using 0.9 fb-1 of ppbar collision data at sqrt(s)=1.96 TeV collected with the D0 detector. We extract R and sigma_ttbar by analyzing samples of events with 0, 1 and >= 2 identified b jets. We measure R = 0.97 +0.09-0.08 (stat+syst) and sigma_ttbar = 8.18 +0.90-0.84 (stat+syst)} +/-0.50 (lumi) pb, in agreement with the standard model prediction.Comment: submitted to Phys.Rev.Letter

Measurement of the B0_s semileptonic branching ratio to an orbitally excited D_s** state, Br(B0_s -> Ds1(2536) mu nu)

In a data sample of approximately 1.3 fb-1 collected with the D0 detector between 2002 and 2006, the orbitally excited charm state D_s1(2536) has been observed with a measured mass of 2535.7 +/- 0.6 (stat) +/- 0.5 (syst) MeV via the decay mode B0_s -> D_s1(2536) mu nu X. A first measurement is made of the branching ratio product Br(b(bar) -> D_s1(2536) mu nu X).Br(D_s1(2536)->D* K0_S). Assuming that D_s1(2536) production in semileptonic decay is entirely from B0_s, an extraction of the semileptonic branching ratio Br(B0_s -> D_s1(2536) mu nu X) is made.Comment: 7 pages, 2 figures, LaTeX, version with minor changes as accepted by Phys.

Measurement of the t-channel single top quark production cross section

The D0 collaboration reports direct evidence for electroweak production of single top quarks through the t-channel exchange of a virtual W boson. This is the first analysis to isolate an individual single top quark production channel. We select events containing an isolated electron or muon, missing transverse energy, and two, three or four jets from 2.3 fb^-1 of ppbar collisions at the Fermilab Tevatron Collider. One or two of the jets are identified as containing a b hadron. We combine three multivariate techniques optimized for the t-channel process to measure the t- and s-channel cross sections simultaneously. We measure cross sections of 3.14 +0.94 -0.80 pb for the t-channel and 1.05 +-0.81 pb for the s-channel. The measured t-channel result is found to have a significance of 4.8 standard deviations and is consistent with the standard model prediction.Comment: 7 pages, 6 figure
