Bereaved university students’ grief experience : what helps and what hinders?
Creators: name: Milis, Lisa
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated what helps and hinders bereaved university students in their experience of grief. Participants consisted of 8 females and 2 males who had experienced the death of a loved one while they were attending university. Nine of the 10 participants perceived their loved one’s death as unanticipated. Participants were individually interviewed using semi-structured, open-ended interviews consistent with Flanagan’s (1954) Critical Incident Technique. A total of 149 critical incidents were extracted from participants’ interviews. Of these, 99 were incidents that participants perceived as helpful to their grieving process. Fifty incidents were perceived as hindering. Using a process of inductive reasoning, the critical incidents were grouped into 17 categories based on the nature of the incident and the meaning the incident held for participants. The study yielded 9 categories of helpful incidents and 8 categories of hindering incidents. A series of credibility checks were conducted to strengthen the credibility of the findings. Nine of the 10 participants provided feedback on summaries of their incidents. An independent rater categorised a random sample of 20% of the incidents and agreed with the researcher’s categorisation in 90% of helpful incidents and 100% of hindering incidents. The main helpful categories identified in this study were: helpful social support; connecting with others who have experienced loss; helpful responses from university staff; connecting with one’s family; maintaining a connection with the deceased; and experiencing school as helpful. The main hindering categories were: unhelpful social responses; not having time to grieve amidst the pressures of school; family dynamics; and unsupportive responses from university staff. The results affirm many of the findings in the existing literature on student bereavement. Dealing with grief can significantly hinder a university student’s academic and social functioning and personal development. It is therefore critical that students have access to support and resources to aid them in their grief recovery. By articulating the factors that help or hinder students’ grieving, the results of this inquiry provide insight into how universities can intervene on behalf of bereaved students to promote their personal, academic, and social well-being.

description: Abstract: Research into responsible management education has largely focused on the merits, attributes, and transformation opportunities to enhance responsible business school education aims. As such, a prominent part of the literature has occupied itself with examining if responsible management modules are inherently considered a non-crucial element of the curriculum and determining the extent to which business schools have introduced such learning content into their curriculum. However, there has been scant research into how to apply novel teaching approaches to engage students and promote responsible management education endeavours. As such, this paper seeks to address this gap through the development of a teaching framework to support educators in designing effective learning environments focused on responsible management education. We will draw on constructivist learning theories and Lego Serious Play (LSP) as a learning enhancement approach to develop a pedagogical framework. LSP is selected due to its increasing application in learning environments to help promote critical discourse, and engage with highly complex problems, whether these are social, economic, environmental, or organisational.

description: We report FUSE and new deep optical spectroscopic observations of PN G 135.9+55.9, the most oxygen-poor planetary nebula located in the Galactic halo. These observations allow us to estimate the gravity of the central star by fitting the profile of the observed H I absorption lines with NLTE model atmospheres. Our best fit implies that the central star is still in a pre-white dwarf stage. We also find large variability of the radial velocities of the absorption component of the Balmer lines on a timescale of hours. This is direct evidence that the nucleus of PN G 135.9+55.9 is a close binary. The large semi-amplitude of the radial velocity variations and the probably short period suggest a massive compact companion, likely a white dwarf. Although our orbital solutions are very preliminary, they indicate that the total mass of the system probably exceeds the Chandrasekhar limit. If confirmed, this would make this binary the potential progenitor of a type Ia supernova.

description: We study a Dark Matter (DM) model in which the dominant coupling to the standard model occurs through a neutrino-DM-scalar coupling. The new singlet scalar will generically have couplings to nuclei/electrons arising from renormalizable Higgs portal interactions. As a result the DM particle $X$ can convert into a neutrino via scattering on a target nucleus $\mathcal{N}$: $ X + \mathcal{N} \rightarrow ν+ \mathcal{N}$, leading to striking signatures at direct detection experiments. Similarly, DM can be produced in neutrino scattering events at neutrino experiments: $ ν+ \mathcal{N} \rightarrow X + \mathcal{N}$, predicting spectral distortions at experiments such as COHERENT. Furthermore, the model allows for late kinetic decoupling of dark matter with implications for small-scale structure. At low masses, we find that COHERENT and late kinetic decoupling produce the strongest constraints on the model, while at high masses the leading constraints come from DM down-scattering at XENON1T and Borexino. Future improvement will come from CE$ν$NS data, ultra-low threshold direct detection, and rare kaon decays.

description: We show that the geometric phase between any two states, including orthogonal states, can be computed and measured using the notion of projective measurement, and we show that a topological number can be extracted in the geometric phase change in an infinitesimal loop near an orthogonal state. Also, the Pancharatnam phase change during the passage through an orthogonal state is shown to be either $π$ or zero (mod $2π$). All the off-diagonal geometric phases can be obtained from the projective geometric phase calculated with our generalized connection.

description: En el presente articulo exploramos el papel de los PSA en la proteccion de la biodiversidad en paises en desarrollo. Para ello analizamos el vinculo entre biodiversidad y servicio ambientales. Exploramos que complejidades inherentes a su naturaleza ecologica emergen a la hora de su cuantificacion, monitoreo y evaluacion economica. A continuacion interpretamos este marco teorico a traves de 11 proyectos de PSA biodiversidad en paises en desarrollo donde analizamos su impacto para la conservacion y el desarrollo rural. El metanalisis muestra que los pagos genericos por biodiversidad suelen requerir menos monitoreo y estan asociados a pagos por superficie, meintras que los pagos para conservar especies emblematicas suelen realizarse por hogar y estan sujetos a un mayor seguimiento y control. Estos proyectos han obviado debates academicos sobre la funcionalidad y el monitoreo de la biodiversidad, optando por soluciones pragmaticas como el heco de ligar la biodiversidad a especies emblematicas o al uso de la tierra. Por ello discutimos e identificamos algunos elementos para avanzar hacia nuevas conceptualizaciones de PSA que se ajusten mas a las necesidades locales de cada region. The present paper analyses the links between Payments for Environmental Services (PES) and biodiversity conservation in developing countries. We first discuss some of the inherent complexities and uncertainties when linking biodiversity to ecosystem services and the related inconsistencies to deal with ecosystem services monitoring, quantification and biodiversity economic valuation. We then apply such theoretical framework in 11 biodiversity PES field projects to evaluate the impacts on biodiversity conservation and rural development. We find that PES designed for conserving ecosystem biodiversity with no concrete species targeting, require less monitoring and payments are done on a per surface basis. Biodiversity PES projects targeting concrete species require more monitoring and control and payments are done on a per family basis. These projects have not addressed the polemic of the lack of consistent links between ecosystem functions and biodiversity, and have adopted a practical approach where biodiversity depends on land uses or target specific species threaten by extinction. We finally suggest some design features to better adjust PES to local needs while coping with forthcoming socio-economic challenges.

description: En los ultimos anos la volatilidad de los mercados agrarios ha aumentado notablemente. En este articulo se analizan las causas de este aumento, abordandose cuestiones como el deficit de liveralizacion existente en el comercio agrario internacional, la especulacion financiera en los mercados de futuros o el aumento de la demanda de granos para producir biocombustibles. Aunique importantes, se recoge como el factor clave y originario es que desde el ano 2000 y como consecuencia del fuerte crecimento de paises emergentes como Brasil, China o India, se ha producido un mayor crecimiento de la demanda de alimentos que de la oferta de alimentos, hasta llegar unos niveles minimos historicos de los stocks mundiales de materias primas. Teniendo en cuenta que la presion de la demanda de alimentos de una poblacion mundial creciente se vera agudizada en las proximas decadas por los impactos del cambio climatico sobre la productividad agraria, se senala que la adopcion de tecnologias sostenibles ya existentes, junto con la generacion y adaptacion de nuevas tecnologias, permitiria que en las proximas decadas los mercados agrarios estuvieran mas equilibrados, lo que llevaria a una situacion de precios de los alimentos mas estables, y a su vez a una mejora de la seguridad alimentaria mundial. Pero, para ello es necesario tambien que se fortalezcan las instituciones agrarias, se disenen y apliquen las politicas agrarias adecuadas y aumente la inversion publica y privada en la agricultura. In recent years the volatility of agricultural markets has increased significantly. This paper analyzes the causes of this increase, addressing issues such as lack of existing liberalization in international agricultural trade, financial speculation in futures markets or increased demand for grain to produce biofuels. It is signaled as a key and original cause, the higher increase since 2000, in demand for food than supply as consequence of the strong growth in emerging countries as Brazil China or India, and resulted low levels of world stocks of raw materials. Given the pressure of demand for food from a growing world population will be exacerbated in coming decades by the impacts of climate change on agricultural productivity, it is noted that the adoption of sustainable technologies already exist, along with the generation and adaptation of new technologies, would allow in the coming decades the agricultural markets were more balanced, leading to a situation of food prices more stable, and in turn to improved food security. But this requires also the strengthening of agricultural institutions, the design and implementation of suitable agricultural policies and the increase of public and private investment in agriculture.
The dynamics of precessing binary black holes using the post-Newtonian approximation

description: We investigate the (conservative) dynamics of binary black holes using the Hamiltonian formulation of the post-Newtonian (PN) equations of motion. The Hamiltonian we use includes spin-orbit coupling, spin-spin coupling, and mass monopole/spin-induced quadrupole interaction terms. In the case of both quasi-circular and eccentric orbits, we search for the presence of chaos (using the method of Lyapunov exponents) for a large variety of initial conditions. For quasi-circular orbits, we find no chaotic behavior for black holes with total mass 10 - 40 solar masses when initially at a separation corresponding to a Newtonian gravitational-wave frequency less than 150 Hz. Only for rather small initial radial distances, for which spin-spin induced oscillations in the radial separation are rather important, do we find chaotic solutions, and even then they are rare. Moreover, these chaotic quasi-circular orbits are of questionable astrophysical significance, since they originate from direct parametrization of the equations of motion rather than from widely separated binaries evolving to small separations under gravitational radiation reaction. In the case of highly eccentric orbits, which for ground-based interferometers are not astrophysically favored, we again find chaotic solutions, but only at pericenters so small that higher order PN corrections, especially higher spin PN corrections, should also be taken into account.

The experience of "What-iffing" in deciding if, and when, to have children
Creators: name: Munson, Suzanne Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: In this phenomenological study the experience of "what-iffing" when making the decisions of if, and when, to have a child, was explored for six women. In-depth interviews were conducted in an initial attempt to answer the question: What is the experience of "what-iffing" as experienced by women when faced with making the decisions of if, and when, to have children? Six common themes emerged from the data analysis: 1)A Sense of Biological Pressure, 2) A Sense of a Lack of Readiness, 3) A Fear of Making the Wrong Decision, 4) "What-iffing" as a Reflection of an Inability to Make a Decision, 5) The Pervasive Nature of "What-iffing" Behaviour, and 6) A Sense of "What-iffing" as Being both Adaptive and Maladaptive. The results suggest that "what-iffing" behaviour may be a synthetic construct in that it appears to reflect regret; worry; self-doubt; and intolerance of uncertainty. "What-iffing" behaviour also appears to add to the research supporting the non-linear nature of decision-making, particularly as it relates to making parenthood decisions. The findings and limitations of this study have several implications for counselling practice and future research.

description: We present the computation of a full set of planar five-point two-loop master integrals with one external mass. These integrals are an important ingredient for two-loop scattering amplitudes for two-jet-associated W-boson production at leading color in QCD. We provide a set of pure integrals together with differential equations in canonical form. We obtain analytic differential equations efficiently from numerical samples over finite fields, fitting an ansatz built from symbol letters. The symbol alphabet itself is constructed from cut differential equations and we find that it can be written in a remarkably compact form. We comment on the analytic properties of the integrals and confirm the extended Steinmann relations, which govern the double discontinuities of Feynman integrals, to all orders in $ε$. We solve the differential equations in terms of generalized power series on single-parameter contours in the space of Mandelstam invariants. This form of the solution trivializes the analytic continuation and the integrals can be evaluated in all kinematic regions with arbitrary numerical precision.

description: El estudio del fenomeno economico de transmision de precios, asi como de la integracion de mercados ha recibido gran atencion por parte de la comunidad academica, asi como de diversos organizmos gubernamentales y no gubernamentales. Es de particular interes la integracion de los mercados a nivel internacional, debido al impacto, negativo o positivo, que pueda tener los mercados internacionales en los mercados regionales, en especial en los paises en desarrollo. La presente investigacion demuestra que existe cierto grado de integracion entre los mercados de maiz en Mexico y los Estados Unidos en base al analisis de transmision de precios, siendo este grado de cointegracion diferente para las distintas regiones en Mexico. Los modelos evaluados con diferentes metodologias, lineales y no linealesm sugieren que los precios en las todas las regiones en Mexico se ajustand a los cambios de precio en los Estados Unidos a diferentes velocidades, este hecho evidencia que los precios de maiz en Mexico se determinan en cierta medida en funcion de los precios los Estados Unidos. Asimismo en analisis de asimetria de precios sugiere la existencia de poder de mercado entre los importadores de maiz en Mexico como una explicacion a las diferentes velocidades de ajuste que se observan en las distintas regiones en Mexico. The study of price transmission and market integration have received great attention, not only from the scientific community, but also from international organizations and national governments. Of particular interest is market integration at the international level given the impact (positive or negative) on regional markets, specifically in developing countries. Using price transmission analysis, the present research shows that maize markets in Mexico and the United States (US) are cointegrated. Furthermore, the research shows that the degree of cointegration is different for each regional market in Mexico. The different methodologies used here, linear and non-linear, suggest that Mexican prices adjust to changes in US prices at different speeds depending on the region. This outcome serves as evidence that Mexican prices are functions of US prices, with the asymmetric price transmission analysis suggesting market power among maize importers in Mexico.

description: The thermal properties of graphitic ribbon are investigated based on Brenner's empirical potential. The reliability and usefulness of the empirical potential to address the thermal properties of covalent-bonded carbon nanostructures are verified through a comparison of phonon dispersion relations and the density of states of carbon nanotubes with first-principles calculations. The analysis reveals unique edge-phonon states that are highly localized at edge carbon atoms of both armchair and zigzag ribbons. Applying the phonon dispersion relations to the Landauer formula of phonon transport, the quantization and universal features of the low-temperature thermal conductance of graphitic ribbon are elucidated, and it is found that the width of the quantization plateau in the low-temperature region is inversely proportional to the ribbon width.

description: We perform a detailed analysis of the band structure, phonon dispersion, and electron-phonon coupling of three types of small-radius carbon nanotubes (CNTs): (5,0), (6,0), and (5,5) with diameters 3.9, 4.7, and 6.8 Årespectively. The large curvature of the (5,0) CNTs makes them metallic with a large density of states at the Fermi energy. The density of states is also strongly enhanced for the (6,0) CNTs compared to the results obtained from the zone-folding method. For the (5,5) CNTs the electron-phonon interaction is dominated by the in-plane optical phonons, while for the ultrasmall (5,0) and (6,0) CNTs the main coupling is to the out-of-plane optical phonon modes. We calculate electron-phonon interaction strengths for all three types of CNTs and analyze possible instabilities toward superconducting and charge-density wave phases. For the smallest (5,0) nanotube, in the mean-field approximation and neglecting Coulomb interactions, we find that the charge-density wave transition temperature greatly exceeds the superconducting one. When we include a realistic model of the Coulomb interaction we find that the charge-density wave is suppressed to very low temperatures, making superconductivity dominant with the mean-field transition temperature around one K. For the (6,0) nanotube the charge-density wave dominates even with the inclusion of Coulomb interactions and we find the mean-field transition temperature to be around five Kelvin. We find that the larger radius (5,5) nanotube is stable against superconducting and charge-density wave orders at all realistic temperatures.

The experience of recovery from an eating disorder : an interpretive phenomenological description
Creators: name: Maltby, Georgina Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: Although eating disorders are a significant problem for some women, there is a lack of understanding of what recovery entails and what it means to be recovered. The purpose of this study was to describe the experience of recovery from an eating disorder drawing on the Empirical Phenomenological Psychological method (Karlsson, 1993). Eight women participated in in-depth interviews that explored their recovery experience. The women ranged in age from 28 to 53 years. All of the women had been recovered for a minimum of 5 years (M= 10 years; Range = 5 to 18 years). I conducted a phenomenological interpretive analysis of the transcribed interviews, which produced a description of each participant's recovery experience (i.e., situated structure). Next, I developed the general structure and essential themes of the experience of recovery across all participants, and the commonalities in "being recovered" as revealed in the existentials of body, time, space, and relation (Van Manen, 2000). The findings revealed that there was a common structure to the experience of recovery. Three themes were essential to the recovery experience: (a) knowingness and allowing what is needed to recover; (b) deepening awareness and discovery of oneself; and (c) deepening of being, discovering, and embracing life's possibilities. A l l of the women in this study acknowledged a full recovery, albeit a long, difficult, and lonely experience that required courage, persistence, and determination. The women in this study described an agentic, strategic, and a faith-based approach to recovery that mirrored, resisted, and offered alternatives to the dominant societal and medical discourses of eating disorders and recovery. Future research that explores a multifaceted experience of recovery, and interventions that facilitate self-reflection in order to deepen awareness of the individual's experience and responsibility for change may be helpful.

description: We present BVRIK images and spectroscopic observations of the z=0.17 host galaxy of the compact steep-spectrum radio source MRC B1221-423. This is a young (~1e5 yr) radio source with double lobes lying well within the visible galaxy. The host galaxy is undergoing tidal interaction with a nearby companion, with shells, tidal tails, and knotty star-forming regions all visible. We analyse the images of the galaxy and its companion pixel-by-pixel, first using colour-magnitude diagrams, and then fitting stellar population models to the spectral energy distributions of each pixel. The pixels separate cleanly in colour-magnitude diagrams, with pixels of different colours occupying distinct regions of the host galaxy and its companion. We find three distinct groups of ages: an old population in the outskirts of the host galaxy; an intermediate-age population around the nucleus and tidal tail, and a young population in the nucleus and blue "knots". The correlation of age with position suggests the two most recent episodes were triggered by tidal interactions with the companion galaxy. The evidence points to the AGN in the centre of B1221-423 having been "caught in the act" of ignition. However, none of the components we have identified is as young as the radio source, implying that the delay between the interaction and the triggering of the AGN is at least 300 My.

Equilibrium Bundle Size of Rodlike Polyelectrolytes with Counterion-Induced Attractive Interactions

description: Multivalent counterions can induce an effective attraction between like-charged rodlike polyelectrolytes, leading to the formation of polelectrolyte bundles. In this paper, we calculate the equilibrium bundle size using a simple model in which the attraction between polyelectrolytes (assumed to be pairwise additive) is treated phenomenologically. If the counterions are point-like, they almost completely neutralize the charge of the bundle, and the equilibrium bundle size diverges. When the counterions are large, however, steric and short-range electrostatic interactions prevent charge neutralization of the bundle, thus forcing the equilibrium bundle size to be finite. We also consider the possibility that increasing the number of nearest neighbors for each rod in the bundle frustrates the attractive interaction between the rods. Such a frustration leads to the formation of finite size bundles as well, even when the counterions are small.

Year: 2025

description: Теория игр представляет собой математический метод анализа стратегического взаимодействия между рациональными агентами, принимающими решения в условиях конфликта или сотрудничества. Она изучает модели, в которых исход зависит от действий нескольких участников, каждый из которых стремится максимизировать свою выгоду. Основными элементами теории игр являются игроки, стратегии, выигрыши и равновесия, такие как равновесие Нэша, которое описывает ситуацию, когда ни один из игроков не может улучшить свой результат, изменяя свою стратегию в одностороннем порядке.

description: The paper analyzes the volume and structure of self-supply in farmers’ households according to their financial condition. To evaluate that condition a synthetic index was constructed using the classical TOPSIS method. The basic source of information was the unpublished raw microdata on individual households from the Household Budget Survey conducted by the Central Statistical Office in 2010. Conducted analysis allowed to assert that among the households with the best financial condition, which represented 17.5% of all farmers’ households, the average disposable income was more than three times higher than that of the households with the worst financial condition, which represented 15% of the group. Moreover, it was observed that better financial condition implies lower percentage of households that use self-supply.

description: We identify a length scale that simultaneously accounts for the observed proton-nucleus reaction cross section and diffraction peak in the proton elastic differential cross section. This scale is the nuclear radius, $a$, deduced from proton elastic scattering data of incident energies higher than $\sim800$ MeV, by assuming that the target nucleus is a ``black'' sphere. The values of $a$ are determined so as to reproduce the angle of the first diffraction maximum in the scattering data for stable nuclei. We find that the absorption cross section, $πa^2$, agrees with the empirical total reaction cross section for C, Sn, and Pb to within error bars. This agreement persists in the case of the interaction cross section measured for a carbon target. We also find that $\sqrt{3/5}a$ systematically deviates from the empirically deduced values of the root-mean-square matter radius for nuclei having mass less than about 50, while it almost completely agrees with the deduced values for $A\gtrsim50$. This tendency suggests a significant change of the nuclear matter distribution from a rectangular one for $A\lesssim50$, which is consistent with the behavior of the empirical charge distribution.

description: The paper presents assessment of relation between propriety of agricultural practices and perception of selected risk factors among Polish farmers. In addition, the relation between agricultural practices and perception of technology impact on risk reduction has been investigated. The research has been conducted on representative sample of 405 farms participation in Polish FADN (Farm Accountancy Data Network). Only farm in following type of production has been taken: field crops, horticulture, permanent crops, mixed crops. The research revealed that higher level of agricultural practice’s propriety is generally connected with lower assessment of risk factors’ importance and higher perception of technology impact on risk reduction’s possibility.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Understanding family practice residents’ conceptualization and experience of empathy
Creators: name: Van Tongeren, Carlene
Publisher: name: University of British Columbia
Year: 2010

description: A major problem in the medical profession is a lack of empathic communication skills in doctor-patient interactions. Studies have illustrated medical students’ ability to learn effective communication skills, yet have found their empathy for patients to decline during the senior years of medical school and residency. Focus group interviews were conducted with Family Practice Residents from the University of British Columbia Medical School Program to investigate how they conceptualize and experience empathy in the medical context in order to better understand the processes involved in learning and understanding empathy as well as the barriers in transferring these skills to clinical practice. Themes were generated under five main categories including "The Characteristics of Empathy in the Medical Context"; "The Value of Empathy in the Medical Context"; "The Facilitating Factors in the Development of Empathy"; "The Hindering Factors in the Development of Empathy"; "The Challenging Factors in the Use of Empathy". Suggestions were developed regarding the implications of these findings for clinical training and practice as well as future research.
