The resilient entrepreneur: the use of successful coping behaviours to experience relief from emotional intensity by entrepreneurs in Canada

There is a lack of qualitative research demonstrating the emotional processes that entrepreneurs experience after they first start their businesses. This dissertation analyzed the emotional processes experienced by ten entrepreneurs during their venture’s start-up phase. A constructivist grounded theory research design was used to collect and analyze data in this investigation. Research findings showed entrepreneurs experienced simultaneous emotions that were of an intense nature during their early stages of business. These emotions included some combination of: excitement, anxiety/fear, disappointment, pressure/self-doubt, isolation, and relief. In addition, entrepreneurs identified entrepreneurial distress related to the constant need for action in their ventures and the use of technology, including cellular phones, email, and social media. Entrepreneurs described a gradual reduction in emotional intensity as they gained experience and learned how to cope. Coping behaviours used by entrepreneurs to counteract the overwhelming nature of emotions were: (a) developing improved entrepreneurial social networks, (b) gaining experience/learning from mistakes, and (c) changing their perspective on life as a whole. Coping behaviours aided in the reduction and fluctuation of entrepreneurial emotions

Moments of the neutron g(2) structure function at intermediate Q(2)

We present new experimental results for the He-3 spin structure function g(2) in the resonance region atQ 2 values between 1.2 and 3.0 (GeV/c)(2). Spin dependent moments of the neutron were extracted. Our main result, the inelastic contribution to the neutron d(2) matrix element, was found to be small at \u3c Q(2)\u3e = 2.4 (GeV/c)(2) and in agreement with the lattice QCD calculation. The Burkhardt-Cottingham sum rule for He-3 and the neutron was tested with the measured data and using the Wandzura-Wilczek relation for the low x unmeasured region

Hard Two-Body Photodisintegration of He-3

We have measured cross sections for the gamma He-3 -\u3e pd reaction at photon energies of 0.4-1.4 GeV and a center-of-mass angle of 90 degrees. We observe dimensional scaling above 0.7 GeV at this center-of-mass angle. This is the first observation of dimensional scaling in the photodisintegration of a nucleus heavier than the deuteron

Spectroscopy of Li-9(Lambda) by electroproduction

Background: In the absence of accurate data on the free two-body hyperon-nucleon interaction, the spectra of hypernuclei provides information on the details of the effective hyperon-nucleon interaction. Purpose: To obtain a high-resolution binding-energy spectrum for the Be-9(e, e\u27 K+) Li-9(Lambda) reaction. Method: Electroproduction of the hypernucleus Li-9(Lambda) has been studied for the first time with sub-MeV energy resolution in Hall A at Jefferson Lab on a Be-9 target. In order to increase the counting rate and to provide unambiguous kaon identification, two superconducting septum magnets and a ring imaging Cherenkov detector were added to the Hall A standard equipment. Results: The cross section to low-lying states of Li-9(Lambda) is concentrated within 3 MeV of the ground state and can be fit with four peaks. The positions of the doublets agree with theory while a disagreement could exist with respect to the relative strengths of the peaks in the doublets. The Lambda separation energy, B-Lambda, of 8.36 +/- 0.08 (stat.) +/- 0.08 (syst.) MeV was measured, in agreement with an earlier experiment

Community Perspectives on the Impact of Climate Change on Health in Nunavut, Canada

The purpose of this study was to explore community perspectives on the most important ways that climate change is affecting the health of northern peoples. The study was conducted in Iqaluit, Nunavut, using a participatory action approach and the photovoice research method. Participants identified themes and patterns in the data and developed a visual model of the relationships between the themes identified. Five themes emerged from the data: the direct impacts of climate change on the health of individuals and communities, the transition from past climates to future climates, necessary adaptation to the changing climate in the North, the call to action (individual, regional, and national), and reflection on the past and changing knowledge systems. A climate change and health model was developed to illustrate the relationships between the themes. Participants in this study conceptualized health and climate change broadly. Participants believed that by engaging in a process of ongoing reflection, and by continually incorporating new knowledge and experiences into traditional knowledge systems, communities may be better able to adapt and cope with the challenges to health posed by climate change.L’objectif de cette étude consistait à explorer diverses perspectives communautaires quant aux manières les plus importantes dont le changement climatique a des incidences sur la santé des gens du Nord. L’étude a été réalisée à Iqaluit, au Nunavut, au moyen d’une méthode d’action et de recherche participative faisant appel à la « photovoice ». Les participants ont déterminé les thèmes de même que les tendances caractérisant les données, puis ont abouti à un modèle visuel pour établir des relations entre les thèmes ainsi déterminés. Les données ont donné lieu à la formulation de cinq thèmes, soit les incidences directes du changement climatique sur la santé des gens et des collectivités; la transition des anciens climats aux nouveaux climats; l’adaptation nécessaire au climat changeant dans le Nord; un appel à l’action (individuel, régional et national); et une réflexion sur les systèmes de savoir du passé qui sont en pleine évolution. Ensuite, un modèle de changement climatique et de santé a été élaboré dans le but d’illustrer les liens existant entre les divers thèmes. Les participants à cette étude ont conceptualisé le changement climatique et ses incidences sur la santé à grande échelle. Ils croyaient qu’en s’adonnant à un processus de réflexion continue et qu’en intégrant constamment de nouvelles connaissances et expériences aux systèmes de savoir traditionnel, les collectivités pourraient être mieux placées pour s’adapter et relever les défis posés par le changement climatique en matière de santé

Injury and performance related biomechanical differences between recreational and collegiate runners

IntroductionRunning related injuries (RRI) are common, but factors contributing to running performance and RRIs are not commonly compared between different types of runners.MethodsWe compared running biomechanics previously linked to RRIs and performance between 27 recreational and 35 collegiate runners. Participants completed 5 overground running trials with their dominant limb striking a force plate, while outfitted with standardised footwear and 3-dimensional motion capture markers.ResultsPost hoc comparisons revealed recreational runners had a larger vertical loading rate (194.5 vs. 111.5 BW/s, p < 0.001) and shank angle (6.80 vs. 2.09, p < 0.001) compared with the collegiate runners who demonstrated greater vertical impulse (0.349 vs. 0.233 BWs, p < 0.001), negative impulse (−0.022 vs. −0.013 BWs, p < 0.001), positive impulse (0.024 vs. 0.014 BWs, p < 0.001), and propulsive force (0.390 vs. 0.333 BW, p = 0.002). Adjusted for speed, collegiate runners demonstrated greater total support moment (TSM), plantar flexor moment, knee extensor moment, hip extensor moment, and had greater proportional plantar flexor moment contribution and less knee extensor moment contribution to the TSM compared with recreational runners. Unadjusted for speed, collegiate runners compared with recreational had greater TSM and plantar flexor moment but similar joint contributions to the TSM.DiscussionGreater ankle joint contribution may be more efficient and allow for greater capacity to increase speed. Improving plantarflexor function during running provides a strategy to improve running speed among recreational runners. Moreover, differences in joint kinetics and ground reaction force characteristics suggests that recreational and collegiate runners may experience different types of RRI

Topological Phases near a Triple Degeneracy

We study the pattern of three state topological phases that appear in systems with real Hamiltonians and wave functions. We give a simple geometric construction for representing these phases. We then apply our results to understand previous work on three state phases. We point out that the ``mirror symmetry'' of wave functions noticed in microwave experiments can be simply understood in our framework.Comment: 4 pages, 1 figure, to appear in Phys. Rev. Let

Quark-Hadron Duality in Neutron (3He) Spin Structure

We present experimental results of the first high-precision test of quark-hadron duality in the spin-structure function g_1 of the neutron and $^3$He using a polarized 3He target in the four-momentum-transfer-squared range from 0.7 to 4.0 (GeV/c)^2. Global duality is observed for the spin-structure function g_1 down to at least Q^2 = 1.8 (GeV/c)^2 in both targets. We have also formed the photon-nucleon asymmetry A_1 in the resonance region for 3He and found no strong Q^2-dependence above 2.2 (GeV/c)^2.Comment: 13 pages, 3 figure

Moments of the neutron g2g_2 structure function at intermediate Q2Q^2

We present new experimental results of the $^3$He spin structure function $g_2$ in the resonance region at $Q^2$ values between 1.2 and 3.0 (GeV/c)$^2$. Spin dependent moments of the neutron were then extracted. Our main result, the resonance contribution to the neutron $d_2$ matrix element, was found to be small at $$=2.4 (GeV/c)$^2$ and in agreement with the Lattice QCD calculation. The Burkhardt-Cottingham sum rule for $^3$He and the neutron was tested with the measured data and using the Wandzura-Wilczek relation for the low $x$ unmeasured region. A small deviation was observed at $Q^2$ values between 0.5 and 1.2 (GeV/c)$^2$ for the neutron

Longer fixation duration while viewing face images

The spatio-temporal properties of saccadic eye movements can be influenced by the cognitive demand and the characteristics of the observed scene. Probably due to its crucial role in social communication, it is argued that face perception may involve different cognitive processes compared with non-face object or scene perception. In this study, we investigated whether and how face and natural scene images can influence the patterns of visuomotor activity. We recorded monkeys’ saccadic eye movements as they freely viewed monkey face and natural scene images. The face and natural scene images attracted similar number of fixations, but viewing of faces was accompanied by longer fixations compared with natural scenes. These longer fixations were dependent on the context of facial features. The duration of fixations directed at facial contours decreased when the face images were scrambled, and increased at the later stage of normal face viewing. The results suggest that face and natural scene images can generate different patterns of visuomotor activity. The extra fixation duration on faces may be correlated with the detailed analysis of facial features
