title: An investigation of the association between catastrophic thoughts and anxiety in people with respiratory diseases
Creators: name: Sutton, Karen
Publisher: name: The Open University
Year: 1996

description: The purpose of this study was to investigate whether the cognitive model of panic may explain the high levels of anxiety that have been reported amongst people with Chronic Obstructive Pulmonary Disease (COPD) (Carr et al, 1994). In previous research, cognitive variables, assessed on general measures of catastrophizing (such as the Agoraphobic Cognitions Questionnaire), have been shown to be strongly predictive of anxiety in people with COPD, regardless of severity or duration of the respiratory disease. One of the aims of this study was to develop a questionnaire to elicit specific cognitions in response to a range of COPD-related symptoms presented in different situations. Favourable reliability and validity were demonstrated for the questionnaire, and its completion by 37 people with COPD produced a range of cognitions of differing severity. High levels of anxiety (assessed using the Hospital Anxiety and Depression scale) were found in the group (more than 27%). More severe catastrophic thoughts were found to be strongly predictive of greater anxiety, particularly for specific anxiety ratings on the new questionnaire, and this relationship was more significant when cognitions and anxiety wore elicited by symptoms presented in 'unsafe' situations. Severity and duration of illness were not significant predictors of anxiety, but social support was strongly predictive of generalized anxiety. In the light of the adverse consequences of anxiety with regards to appropriate coping with respiratory disease, an exploration of the use of cognitive techniques in therapy is suggested.

description: The collinear eZe configuration of helium, with the electrons on opposite sides of the nucleus, is studied in the presence of an external electromagnetic (laser or microwave) field. We show that the classically unstable "asymmetric stretch" orbit, on which doubly excited intrashell states of helium with maximum interelectronic angle are anchored, can be stabilized by means of a resonant driving where the frequency of the electromagnetic field equals the frequency of Kepler-like oscillations along the orbit. A static magnetic field, oriented parallel to the oscillating electric field of the driving, can be used to enforce the stability of the configuration with respect to deviations from collinearity. Quantum Floquet calculations within a collinear model of the driven two-electron atom reveal the existence of nondispersive wave packets localized on the stabilized asymmetric stretch orbit, for double excitations corresponding to principal quantum numbers of the order of N > 10.

In-Medium Jet Modification Measured by PHENIX Via two-particle Correlations and High $p_T$ Hadrons in $A+A$ Collisions

subject: FOS: Physical sciences

description: The first evidence of jet quenching was observed at RHIC via suppression of single high $p_T$ hadron $R_{AA}$ and the disappearance of the away-side jet peak in two-particle correlations. Since then, hadron $R_{AA}$ and two-particle correlations continue to be useful probes of the QGP in heavy ion collisions, since the particles involved are fragments of the jets produced in the initial hard scattering. PHENIX recently improved the width measurements extracted from $π^0$-hadron correlations after removing the higher order flow terms in the underlying event subtraction. Measurements of the away-side jet correlated with high $p_T$ neutral pions show an increase in low momentum particle production at wide angles consistent with theoretical expectations for energy loss. The system size dependence of energy loss is further investigated at PHENIX by measuring the absolute yield and $R_{AA}$ for various hadron species at high $p_T$ in several collision systems including $U+U$ and $Cu+Au$. These proceedings will present the newest PHENIX $R_{AA}$ and two-particle correlation measurements and their role in our understanding of jet quenching and medium response in heavy ion collisions
The relationship between selected undergraduate status characteristics and factors pertaining to job status twenty-two months after graduation: A study of deaf university graduates
Creators: name: Pollock, Nancy Jean
Publisher: name: American University
Year: 2023

description: This study examined the relationship between selected undergraduate status characteristics (general work and cooperative internship experience) and certain factors pertaining to job status on the initial full-time job held 22 months after graduation (job satisfaction, level of employment, and job growth potential) as assessed through the Alumni Employment Survey (AES), a self-report type instrument developed by the writer. The subjects were 121 deaf male and female 1991 Gallaudet University bachelor of science and bachelor of arts graduates who responded to a mail survey in spring 1993. All were employed part-time or full-time 22 months after graduation. A cross-tabulation chi-square statistical procedure was used to test six hypotheses that predicted a significant relationship between each of the undergraduate status characteristics (general work experience and cooperative education experience) and factors of postgraduation employment (job satisfaction, level of employment, and job growth potential). None of the hypotheses was confirmed at the $p \leq .05$ confidence level. These findings agree with research on job satisfaction (Crammatte, 1987; Center for Career Programs, 1992) and job growth potential (Center for Career Programs, 1992) for deaf persons of all educational levels and for hearing college graduates (Bisconti & Solmon, 1977; Lunneborg, 1982). They suggest the possibility that deaf college graduates are more vocationally mature than previously believed. Also, they run contrary to previous employment studies on deaf persons (Birnbaum, 1982; Rawlings, King, Karchmer, & Brown, 1985) that reported deaf persons of all educational levels to be underemployed. In general, it is concluded that, in this sample of deaf university graduates, undergraduate status characteristics of general work experience and cooperative education experience are not significantly related to perceptions of job satisfaction, level of employment, and job growth potential on the initial full-time postgraduation job.

description: This research investigates the effect of producers’ risk preferences on the adoption of a new technology—machine harvesting—among blueberry producers in the Southeastern United States. Technology adoption literature assumes that risk aversion decreases the likelihood of adopting a new technology, but findings reveal that growers with higher levels of risk aversion are more likely to adopt machine harvesting. One explanation for this discrepancy is that we assume there are risks in both forms of harvest technology. The current patchwork or immigration policy and enforcement has made the availability of manual labor—the status quo technology—increasingly volatile.

description: This research report presents findings about the extent and nature of digital self-harm among New Zealand teens. Digital self-harm is broadly defined here as the anonymous online posting or sharing of mean or negative online content about oneself. The report centres on the prevalence of digital self-harm (or self-cyberbullying) among New Zealand teens (aged 13-17), the motivations, and outcomes related to engaging in this behaviour. The findings described in this report are representative of the teenage population of New Zealand by gender, ethnicity and age. Key findings are: Overall, 6% of New Zealand teens have anonymously posted mean or negative content online about themselves in the past year. Teenagers’ top reasons for this behaviour were: making a joke, wanting to show resilience, looking for friends’ sympathy, and seeking reassurance of friendship. By exploring the nature and extent of this behaviour, we are providing the online safety community, schools and parents with insights about a complex and, to some extent, hidden phenomenon involving New Zealand teens.
Test of CP invariance in vector-boson fusion production of the Higgs boson in the $H\rightarrowττ$ channel in proton$-$proton collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector

description: A test of CP invariance in Higgs boson production via vector-boson fusion is performed in the $H\rightarrowττ$ decay channel. This test uses the Optimal Observable method and is carried out using 36.1 $\mathrm{fb}^{-1}$ of $\sqrt{s}$ = 13 TeV proton$-$proton collision data collected by the ATLAS experiment at the LHC. Contributions from CP-violating interactions between the Higgs boson and electroweak gauge bosons are described by an effective field theory, in which the parameter $\tilde{d}$ governs the strength of CP violation. No sign of CP violation is observed in the distributions of the Optimal Observable, and $\tilde{d}$ is constrained to the interval $[-0.090, 0.035]$ at the 68% confidence level (CL), compared to an expected interval of $\tilde{d} \in [-0.035,0.033]$ based upon the Standard Model prediction. No constraints can be set on $\tilde{d}$ at 95% CL, while an expected 95% CL interval of $\tilde{d} \in [-0.21,0.15]$ for the Standard Model hypothesis was expected.

The Response of Test Masses to Gravitational Waves in the Coordinates of a Local Observer

Publisher: name: arXiv
Year: 2004
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The response of laser interferometers to gravitational waves has been calculated in a number of different ways, particularly in the transverse-traceless and the local Lorentz gauges. At first sight, it would appear that these calculations lead to different results when the separation between the test masses becomes comparable to the wavelength of the gravitational wave. In this paper this discrepancy is resolved. We describe the response of free test masses to plane gravitational waves in the coordinate frame of a local observer and show that it acquires contributions from three different effects: the displacement of the test masses, the apparent change in the photon velocity, and the variation in the clock speed of the local observer, all of which are induced by the gravitational wave. Only when taken together do these three effects represent a quantity which is translationally invariant. This translationally-invariant quantity is identical to the response function calculated in the transverse-traceless gauge. We thus resolve the well-known discrepancy between the two coordinates systems, and show that the results found in the coordinate frame of a local observer are valid for large separation between the masses.

description: This paper examines factors affecting how much consumers spend when purchasing directly from producers. A joint decision framework models two decisions: 1) whether to purchase directly and 2) how much to spend. Consumers with a greater incidence of family disease or who are immigrants, prepare more meals at home, and are more concerned with U.S. food safety also spend more on food purchased directly from producers. Results suggest that farmers should develop a three-pronged marketing strategy by attracting new consumers, adopting sales promotion tools that encourage existing customers to purchase more frequently, and encouraging consumers to spend more per visit.
title: The Effect of Different Weaning Strategies on Piglet Performance and Immune Function
Creators: name: Allen, Mary
Publisher: name: The Open University
Year: 2004

description: The weaning period in commercial pig production has been a continuing problem for both the piglet and producer. An investigation was carried out to assess the effects of different, relatively simple, management strategies on the stress associated with the weaning period in terms of piglet performance, behaviour and immune status. Three of the main areas identified as playing a key part in the stress associated with weaning were mixing of unfamiliar piglets, relocation to a new environment and adaptation to a new diet. Management strategies were designed relating to assess these factors.
 The studies highlighted that mixing piglets pre-weaning at 14 days of age was a positive step to aid the transition of weaning, in terms of performance and immune status and requires little adaptation of current farrowing systems. Mixing at either 7 or 21 days of age does not show the same improvements in post-weaning performance.
 Remaining in a familiar environment was not beneficial, and may possibly be detrimental, to the newly weaned piglet and indeed, relocation to a novel environment appears to be important for the piglet psychologically and motivates the piglet to explore its new environment and search for alternative food sources.
 The benefits of creep feeding still needs further consideration in order to determine the optimal feeding strategy in relation to feed intakes pre- and post-weaning combined with the effects of creep feed on the underdeveloped digestive tract.
 Although it is not possible to completely remove the growth check that occurs post-weaning, it is clear that management strategies can be utilised to reduce the stress associated with weaning and improve post-weaning growth rates.

description: Contemporary studies of food accessibility often disregard ‘ethnic’ grocery retailers as sources of food or assume them to be attractive to all individuals. This body of research also frequently frames access as an issue of spatial proximity to grocery stores. Drawing on thirty interviews I conducted with residents of Humbermede, Toronto, I explore how food accessibility is perceived and experienced in a culturally-diverse neighbourhood where the only grocery retailers present are ethnic in nature. I argue that identity-related factors (food preferences, ethnic identification, language, and attitudes towards difference) and aspects of one’s life circumstances (purchasing power, mobility, and location or length of residence) – not merely distance – coalesce to influence understandings of one’s food retail environment and one’s store patronage decisions. These findings suggest that food shoppers are not homogenous, that all retailers are not equally attractive to all consumers, and that food accessibility has critical socio-cultural, economic, and spatiotemporal components.

 Remarks: This study confirms H. nigritus from the provinces Erzurum, Gümüşhane, Hakkâri, Nevşehir and Van. Interestingly, all samples were collected in July. The species appears to be sporadically distributed in Turkey. Here it occurs between 900–2800 m altitude, but is mainly found above 2000 m, and therefore be considered to be a montane species. In Central Europe it is found from the plain to higher altitudes of the low mountains, in the Alps up to 1600 m (WESTRICH 2018). DATHE & PROSHCHALYKIN (2018) report it from 4000 m altitude in Kyrgyzstan and 2700 m in Tajikistan. This species is only sparsely collected in Turkey (5 provinces).

description: For nearly degenerate neutrinos, quantum corrections can modify the tree-levelmasses via low energy supersymmetric threshold corrections comparable to the solar oscillation mass scale. We numerically calculate corrections to neutrino masses in minimal supergravity (mSugra) and Gauge Mediated Supersymmetry Breaking (GMSB) scenarios and identify parameter spaces in the high energy regime for which the solar neutrino mass splitting becomes too large compared to the LMA solution. We show that such considerations can give bounds on GMSB and mSugra models which can be useful. On the contrary, if we start from degenerate mass eigenvalues at the tree level, these threshold corrections being generation dependent, can also produce the required mass splitting at solar scale for regions of parameter space.

Fatal Panleukopenia Virus Infection In A Lynx Lynx
Feline panleukopenia is a highly contagious disease that infects domestic as well as wild felids worldwide. Historically, and in areas where vaccination is not practiced, panleukopenia has resulted in the death of several cats. As in domestic felids, this disease usually presents with acute onset of symptoms including anorexia, depression, vomiting and diarrhoea. The disease is transmitted by direct contact, fomites and aerosols, and the virus persists for extended periods of up to one year, in the environment. Although modern vaccination practices have reduced the incidence of panleukopenia greatly, and the disease is rare today, its acute onset and high rate of mortality especially in young kittens, turns feline panleukopenia into an infectious disease with considerable impact in captive populations of endangered wild felines.

description: Camera calibration and localization, sometimes simply named camera calibration, enables many applications in the context of soccer broadcasting, for instance regarding the interpretation and analysis of the game, or the insertion of augmented reality graphics for storytelling or refereeing purposes. To contribute to such applications, the research community has typically focused on single-view calibration methods, leveraging the near-omnipresence of soccer field markings in wide-angle broadcast views, but leaving all temporal aspects, if considered at all, to general-purpose tracking or filtering techniques. Only a few contributions have been made to leverage any domain-specific knowledge for this tracking task, and, as a result, there lacks a truly performant and off-the-shelf camera tracking system tailored for soccer broadcasting, specifically for elevated tripod-mounted cameras around the stadium. In this work, we present such a system capable of addressing the task of soccer broadcast camera tracking efficiently, robustly, and accurately, outperforming by far the most precise methods of the state-of-the-art. By combining the available open-source soccer field detectors with carefully designed camera and tripod models, our tracking system, BroadTrack, halves the mean reprojection error rate and gains more than 15% in terms of Jaccard index for camera calibration on the SoccerNet dataset. Furthermore, as the SoccerNet dataset videos are relatively short (30 seconds), we also present qualitative results on a 20-minute broadcast clip to showcase the robustness and the soundness of our system.

description: Large scale molecular dynamics (MD) simulations on two-phase immiscible flows show that associated with the moving contact line, there is a very large $1/x$ partial-slip region where $x$ denotes the distance from the contact line. This power-law partial-slip region is verified in large-scale adaptive continuum simulations based on a local, continuum hydrodynamic formulation, which has proved successful in reproducing MD results at the nanoscale. Both MD and continuum simulations indicate the existence of a universal slip profile in the Stokes-flow regime, well described by $v^{slip}(x)/V_w=1/(1+{x}/{al_s})$, where $v^{slip}$ is the slip velocity, $V_w$ the speed of moving wall, $l_s$ the slip length, and $a$ is a numerical constant. Implications for the contact-line dissipation are discussed.

description: We define a kinetic and a potential energy such that the principle of stationary action from Lagrangian mechanics yields a Camassa--Holm system (2CH) as the governing equations. After discretizing these energies, we use the same variational principle to derive a semi-discrete system of equations as an approximation of the 2CH system. The discretizaton is only available in Lagrangian coordinates and requires the inversion of a discrete Sturm--Liouville operator with time-varying coefficients. We show the existence of fundamental solutions for this operator at initial time with appropriate decay. By propagating the fundamental solutions in time, we define an equivalent semi-discrete system for which we prove that there exists unique global solutions. Finally, we show how the solutions of the semi-discrete system can be used to construct a sequence of functions converging to the conservative solution of the 2CH system.

description: Declining real farm income, increased development, and loss of government agricultural programs have created pressure for smaller-scale farms to enhance farm income, often through diversification into agritourism. This study examines farm shops as a farm diversification strategy by investigating farm shop managers as entrepreneurs and highlighting the strategies and skills required for success through interviews with farm shop owners in the UK. Results of the qualitative analysis show that agricultural entrepreneurs must create a unique identity or brand for their operation, build networks, develop knowledge and talent, and build business acumen in order to creatively overcome obstacles and manage diverse operations.

 Hylaeus (Hylaeus) orientalicus (WARNCKE, 1981) – ITIS (2020).
 Material examined: Antalya: Manavgat 5 km W, 10 m, 17.06.1987, 2 , leg. R. Hensen. Mersin: Erdemli 25 km NW, Toros dağları, 900 m, 06.06.1991, , leg. S. Kadlec.
 Remarks: H. orientalicus is very conspicuous by the oblique impressions in the face of the male, so that the findings of such animals hardly remain hidden. It was described from the provinces Kilis, Adana and Şanlıurfa, as well as from Israel. This study adds specimens from Antalya and Mersin. Accordingly, the species is spread in the eastern Mediterranean and south-eastern Anatolia. Our data suggest that H. orientalicus is a thermophilic species mainly from the lowlands, but collected up to 900 m above sea level. It is sparsely collected in Turkey (5 provinces).
 Distribution: This taxon shows a confined distribution range between Israel and Turkey. In Turkey: Adana, Kilis (type locality), Şanlıurfa (WARNCKE 1981); Antalya, Mersin.

description: The MUonE experiment aims at a precision measurement of the hadronic vacuum polarization contribution to the muon $g-2$, via elastic muon-electron scattering. Since the current muon $g-2$ anomaly hints at the potential existence of new physics (NP) related to the muon, the question then arises as to whether the measurement of hadronic vacuum polarization in MUonE could be affected by the same NP as well. In this work, we address this question by investigating a variety of NP explanations of the muon $g-2$ anomaly via either vector or scalar mediators with either flavor-universal, non-universal or even flavor-violating couplings to electrons and muons. We derive the corresponding MUonE sensitivity in each case and find that the measurement of hadronic vacuum polarization at the MUonE is not vulnerable to any of these NP scenarios.

Stochastic dynamics of the magneto-optical trap

description: The cloud of cold atoms obtained from a magneto-optical trap is known to exhibit two types of instabilities in the regime of high atomic densities: stochastic instabilities and deterministic instabilities. In the present paper, the experimentally observed stochastic dynamics is described extensively. It is shown that it exists a variety of dynamical behaviors, which differ by the frequency components appearing in the dynamics. Indeed, some instabilities exhibit only low frequency components, while in other cases, a second time scale, corresponding to a higher frequency, appears in the motion of the center of mass of the cloud. A one-dimensional stochastic model taking into account the shadow effect is shown to be able to reproduce the experimental behavior, linking the existence of instabilities to folded stationary solutions where noise response is enhanced. The different types of regimes are explained by the existence of a relaxation frequency, which in some conditions is excited by noise.

description: We report the discovery of bright, fast, radio flashes lasting tens of seconds with the AARTFAAC high-cadence all-sky survey at 60 MHz. The vast majority of these coincide with known, bright radio sources that brighten by factors of up to 100 during such an event. We attribute them to magnification events induced by plasma near the Earth, most likely in the densest parts of the ionosphere. They can occur both in relative isolation, during otherwise quiescent ionospheric conditions, and in large clusters during more turbulent ionospheric conditions. Using a toy model, we show that the likely origin of the more extreme (up to a factor of 100 or so) magnification events likely originate in the region of peak electron density in the ionosphere, at an altitude of 300-400 km. Distinguishing these events from genuine astrophysical transients is imperative for future surveys searching for low frequency radio transient at timescales below a minute.

A study of career development goals as a function of gender and academic class in a sample of undergraduate architecture students
Creators: name: Waldrep, Lee William
Publisher: name: American University
Year: 2023

description: The primary purpose of this study was to ascertain the "importance" of achieving each of 25 career development goals, as presented on the Career Development Goal Inventory (CDGI), to a sample of undergraduate architecture students, altogether and according to gender and academic class categorizations, and the "success" of their institutions in helping them achieve these goals. A secondary purpose was to calculate the "discrepancy" between the "importance" and the "success" for each of the 25 goals for the total sample and for both gender and academic class. These purposes were addressed through nine research questions. Implications were drawn for their meaning to campus and school of architecture officials and faculty. Participants were a volunteer sample of 261 undergraduates enrolled in schools of architecture at seven universities in the Middle Atlantic region of the United States. Data were gathered using the CDGI, a self-report instrument developed by the researcher. The undergraduate architecture students felt that achieving 24 of the 25 career development goals was from medium to high "importance." They perceived that their institutions had low to medium "success" in assisting them achieve the goals. All of the 25 career development goals had a positive mean "discrepancy," that is, the "importance" of achieving each goal was greater than the institutions' "success" in helping students achieve the goal. Female students attributed significantly more importance than did males to the achievement of nine of the 25 career development goals. Students classified by academic class differed significantly in the "importance" they reported to achieving 10 of the 25 career development goals. The "discrepancy" between gender "importance" and "success" CDGI means was significant for nine goals whereas that for academic class was significant for two. The major conclusion was that undergraduate architecture students need and want more institutional assistance with their career development. Their greatest need appears to be for assistance in obtaining first-time employment. The "success" of institutions in providing assistance for the career development goals considered in this study is low to medium. Finally, gender is suggested by the findings as a basis for differentiating certain features of career development programs in architecture while academic class is not.
Centrality dependence of chemical freeze-out parameters and strangeness equilibration in RHIC and LHC energies

description: We have estimated centrality variation of chemical freeze-out parameters from yield data at mid-rapidity of $π^\pm$, $K^\pm$ and $p$, $\bar{p}$ for collision energies of RHIC (Relativistic Heavy Ion Collider), Beam Energy Scan (RHIC-BES) program, and LHC (Large Hadron Collider). We have considered a simple hadron resonance gas model and employed a formalism involving conserved charges ($B, Q, S$) of QCD for parameterization. Along with temperature and three chemical potentials ($T,μ_B,μ_Q,μ_S$), a strangeness under-saturation factor ($γ_S$) has been used to incorporate the partial equilibration in the strange sector. Our obtained freeze-out temperature does not vary much with centrality, whereas chemical potentials and $γ_S$ seem to have a significant dependence. The strange hadrons are found to deviate from a complete chemical equilibrium at freeze-out at the peripheral collisions. This deviation appears to be more prominent as the collision energy decreases at lower RHIC-BES energies. We have also shown that this departure from equilibrium reduces towards central collisions, and strange particle equilibration may happen after a threshold number of participants in $A$-$A$ collision.

description: In this article we present the Dark-photons$\&$Axion-Like particles Interferometer (DALI), a novel experiment designed for the detection of photon-mixing cold dark matter in the microwave band between 6 and 60 GHz. DALI is a haloscope for the simultaneous search for axions, ALPs and dark photons, with a number of novelties that make it unique. First, it is a dark matter telescope, with a capacity for pointing, tracking and rastering objects and areas in the sky. This potentially allows one to detect relativistic dark matter particles, substructures and flows, without compromising the simultaneous scanning for dark matter relic particles present in the laboratory. Second, it has been designed using commercial technology. This will allow feasible manufacture at a reasonable cost, thereby mitigating the need for R\&D and facilitating maintenance. Finally, it benefits from a high sensitivity over a broad band of frequencies with only minimal reconfiguration.
