    Mental health and career dissatisfaction are of increasing concern to the veterinary profession. The influence of identity on the psychological wellbeing of veterinarians has not been widely explored. Twelve recent veterinary graduates were enrolled in a private social media discussion group, and their identities investigated through narrative inquiry: a methodology which enables identity priorities to be extrapolated from stories of experience. Two distinct variants of the veterinary identity were identified: an academic, ‘diagnosis-focused’ identity, which prioritised definitive diagnosis and best-evidence treatment; and a broader ‘challenge-focused’ identity, where priorities additionally included engaging with the client, challenging environment or veterinary business. Contextual challenges (such as a client with limited finances or difficult interpersonal interactions) were seen as a source of frustration for those with a diagnosis-focused identity, as they obstructed the realisation of identity goals. Overcoming these challenges provided satisfaction to those with a challenge-focused identity. The employment environment of the graduates (general veterinary practice) provided more opportunities for those with a challenge-focused identity to realise identity goals, and more markers of emotional wellbeing were apparent in their stories. Markers of poor emotional health were evident in the stories of those with a diagnosis-focused identity

    Integration of Macro-Fiber Composite Material on a Low Cost Unmanned Aerial System

    Get PDF
    The development, deployment, and operation of Unmanned Aerial Systems (UAS) have grown exponentially in recent years and have provided researchers with the opportunity to gain hands-on experience with aircraft in a manner that was previously limited to institutions and companies with large budgets. This allows the generation and testing of UAS advanced technologies using low cost systems. The scope of this thesis does not aim to make vast improvements to the control strategy itself, but to expand upon previous UAV work carried out at Embry-Riddle by designing, implementing, and demonstrating a simulation environment for mechanical and Macro-Fiber Composite (MFC) actuated ailerons in a Skywalker 1880 UAV using model reference adaptive control law. This work will contribute to a baseline model for the research and development of future UAV with morphing control surfaces up to a flight test stage. Meanwhile the extensive use of low-cost hardware and open source software allows the opportunity to explore the feasibility of using affordable open-source technology in an academic context. Future students who are interested in morphing designs for UAV may find the baseline system presented here to be a useful starting point from which to begin their own research

    We study Dirichlet problems for fractional Laplace equations of the form (Δ)α2u=f(x,u)(-\Delta)^{\frac{\alpha}{2}} u = f(x,u) in Rn\mathbb{R}^{n} for 0<α<n0<\alpha<n where the nonlinearity f(x,u)=i=1Mσiuqi+ωf(x,u) = \sum_{i=1}^{M} \sigma_{i} u^{q_i} + \omega involves sublinear terms with 0<qi<10<q_{i}<1 and the coefficients σi,ω\sigma_{i}, \omega are nonnegative locally finite Borel measures on Rn\mathbb{R}^n. We develop a potential theoretic approach for the existence of positive minimal solutions in Lorentz spaces to the problems under certain assumptions on σi\sigma_{i} and ω\omega. The uniqueness properties of such solutions are discussed. Our techniques are also applicable to similar sublinear problems on uniform bounded domains when 0<α<20<\alpha< 2, or on arbitrary domains with positive Green's functions in the classical case α=2\alpha =2.Comment: 27 page

    Get PDF
    The purpose of this paper was to investigate the effectiveness of SCAMPER technique based on students’ perspective. SCAMPER is an abbreviation of a seven-step idea generation technique which consists of Substitute, Combine, Adapt, Magnify, Modify, Put to another use, Eliminate and Rearrange. Creating a multimedia asset can be a challenge especially when the students are required to produce in a short time of period given. Hence this idea generation technique is introduced to the students to enhance their creativity and speed in their asset creation. This study used a qualitative approach to better understand the difficulties students faced and the effectiveness of SCAMPER technique in creating assets for design and multimedia production. The multimedia assets that the students created is not limited only to video, audio, graphic design, text or 3D models but could be a combination of any of the mentioned medium (Wang, et al, 2012)

    Disability, Mobility & Society [Physical Therapist Assistant Program]

    Get PDF
    Disability, Mobility, & Society is a newly developed assignment for a required level II physical therapy course (SCT 221). It is aimed to familiarize students with the psychosocial and socioeconomic challenges faced by people with physical disability/dysfunction and their immediate community. Students work in teams to develop multimedia pre-recorded video presentations based on actual clinical case studies. Each team will identify and discuss issues related to the specific pathology and impairment, and consider the medical/social/behavioral/financial implications for the individual and the society. The team must present a course of physical therapy intervention that illustrates clinical competence and professional standard of care. Students are encouraged to draw connections to their personal experiences as related to relevant local and/or national healthcare issues. The grading criteria for this assignment is based on the current Global Learning and Oral Communication rubrics. LaGuardia’s Core Competencies and Communication Abilities Main Course Learning Objectives: Instructional: Reinforce effective and appropriate verbal and non-verbal communication with patient/client, the physical therapist, health care delivery personnel, and others. Reinforce individual and cultural differences in all aspects of physical therapy. To develop the student’s global awareness and oral ability. Performance: Demonstrate effective and appropriate verbal and non verbal communication with patient/client, the physical therapist, health care delivery personnel and others. Recognize individual and cultural differences in all aspects of physical therapy. Demonstrate Global Learning using an oral ability through a multimedia presentation based on cases assigned

    Could cities feed themselves? The case of the urban agriculture movement in Cuba = 城市能否自给自足? 古巴城市农业运动调查报告

    Before 1990 the production and market of vegetables in Cuba was monopolized by a large state enterprise where horticultural techniques such as hydroponics and zeoponics are used (in zeolite subtract) with heavy use of chemical products. But, in 1991 due to the Collapse of Soviet Socialist System in Eastern Europe, the Cuban agriculture enters into crisis. Without chemicals pesticides and fertilizers, metal containers, and cement, the hydroponic-zeolite technology could not be used anymore. In this context, the Movement of Urban Agriculture was born in which people produce fresh vegetables intensively applying agro-ecological principles and Organic techniques, consume and directly sell the produce. The Word Health Organization (WHO) and Food and Agriculture Organization (FAO) recommend eating ≥400 g per day of fruits and vegetables (not counting potatoes and other starchy tubers such as cassava). In 1998 the Program produced 75% of the fresh vegetables consumed in the country, that represented 215 grams day per person, and in 2002 it produced 2360.1 tons that represented 576 g day per person. In 2011 the Cuban Urban agriculture produced 1 million 93 mill tonnes of fresh fruit and vegetables. First of all, this impact brings a new perspective to urban reliance opposing a global trend that rural population feeds urban population. Precisely, the main objective of this paper is to show how the Urban Agriculture Movement in Cuba has been successful through developing its potentials to feed its population sustainably. Economically, urban agriculture production permits also production of seeds that the island could start to rely on local production, and at the same time, reduce expenditure by use of biological pest control and organic fertilizers, as much 39 million USD in a year. It is also avoids turning garbage dump into organic gardens in order to reduce pollution in the cities. Finally, this movement constitutes a new source of job opportunities and income to the urban population. The recent International Forum on statement on Nutrition Security of Urban Populations that was celebrated in September 2012, in Naples, Italy, declared that Urban agriculture should be contributed to food availability, food security and nutrition of urban and rural dwellers. It is clear as well, that by using space in cities to grow fruit and vegetables, the ecological footprint could be reduce. The Cuban Urban and Suburban Movement offer facts and arguments to support this hope. The data and facts are collected through continuous investigation and field research in the past five years, and they are discussed in length in book written by the authors: Unfinished Puzzle, Cuban Agriculture: The challenges, lessons and opportunities, edited by Food First, Print in Canada, 2012. 在1990年以前,古巴的蔬菜市场由一国企独家垄断,在种植过程中大量运用化学制品。1991年,东欧社会体制解体,古巴农业陷入危机。没了杀虫剂和化肥,没了金属容器,没了水泥,之前的种植方式无以为继。在这个环境下,城市农业诞生了:人们运用生态农业原则和有机种植方式生产新鲜蔬菜,自种自吃,余下的用来出售。世界卫生组织和粮农组织建议每日食用不少于400g的蔬果(不包括土豆及其它淀粉质块茎)。在1998年,此项目生产的蔬菜占全国消费量的75%,即平均为每人提供了215g的蔬菜。到了2002年,生产总量达230.1吨,即平均为每人每天提供576g蔬果。在2011年,古巴的城市农业生产总量为1,093,000吨。其重要性首先在于,冲击了认为城市人口必须靠农村来养活的固有成见。本文的主要目的在于揭示古巴的城市农业运动是如何成功地发展最大潜力,可持续地养活人民大众。从经济观点来看,这场生产运动使农业留种亦成为可能,这个小岛终于可以开始依赖本地生产。同时,生产成本也得到了降低,因为采用的是生物技术的害虫防治以及有机肥。在这个过程中,垃圾不会被倒入土地,减轻了城市污染问题。最后,这场运动也为城市人口提供了新的就业岗位。2012年九月于意大利那不勒斯召开的“国际城市人口营养安全声明论坛”主张,城市农业必须能保障食物的获取与安全,保障城市和农村居民的营养摄入。另外很明显的一点是,利用城市用地来种植蔬果,碳排放亦会降低。古巴的城市与城郊运动为这一点提供了真实数据,这些数据是过去五年内通过长期实地勘察和数据研究取得的,并且在《未解释之谜,古巴农业:挑战,教训和机遇》(Food First出版,2012年加拿大印刷)一书中有详尽的探讨

    A three-dimensional multidimensional gas-kinetic scheme for the Navier-Stokes equations under gravitational fields

    Full text link
    This paper extends the gas-kinetic scheme for one-dimensional inviscid shallow water equations (J. Comput. Phys. 178 (2002), pp. 533-562) to multidimensional gas dynamic equations under gravitational fields. Four important issues in the construction of a well-balanced scheme for gas dynamic equations are addressed. First, the inclusion of the gravitational source term into the flux function is necessary. Second, to achieve second-order accuracy of a well-balanced scheme, the Chapman-Enskog expansion of the Boltzmann equation with the inclusion of the external force term is used. Third, to avoid artificial heating in an isolated system under a gravitational field, the source term treatment inside each cell has to be evaluated consistently with the flux evaluation at the cell interface. Fourth, the multidimensional approach with the inclusion of tangential gradients in two-dimensional and three-dimensional cases becomes important in order to maintain the accuracy of the scheme. Many numerical examples are used to validate the above issues, which include the comparison between the solutions from the current scheme and the Strang splitting method. The methodology developed in this paper can also be applied to other systems, such as semi-conductor device simulations under electric fields.Comment: The name of first author was misspelled as C.T.Tian in the published paper. 35 pages,9 figure
