    This thesis effort developed a user-oriented query language interface, patterned after IBM\u27s Query-by-Example, for the Mistress relational database. The interface, Mistress/QBE, is written entirely in C and uses the UNIX curses library of subroutines to allow full screen input and output. Mistress /QBE allows the user to issue commands to draw pictorial representations of tables which exist in the database. The user then enters values and operators into the tables to specify a query by indicating attributes to be used in conditional selections, sort and grouping orders, and output formats. Mistress /QBE decodes the information entered on the screen and formulates a Mistress Query Language command which is passed to the Mistress standard C language interface for execution. With a few minor exceptions, any query which can be written in the Mistress Query language can also be written in Mistress/QBE. The interface also includes a high-level operator- called grouping, which is supported by IBM\u27s QBE but not by native Mistress

    Sociogeneses, activity and ontogeny.

    Understanding relations between the social and cognitive contributions to thinking and acting has become a pressing goal for psychological theorizing. Central to understanding these relations is the negotiation and construction of knowledge that is comprised of the inter-psychological processes that engage both cognitive and social experiences. This paper proposes that these processes can be understood through a complex of relations among different sociogenetic sources and between those sources and individuals' agency as constituted by their life histories or ontogenies. Rather than a single sociogenetic source, the social contributions are held to have historical-cultural and situational geneses. However, through inter-psychological processes these contributions are mediated by individuals' unique and socially shaped cognitive experiences. Findings from an investigation of the same vocational practice (hairdressing) conducted in four different work settings are used to identify tentative relations between the sociogeneses of the goal-directed activities that individuals engage in, and how these individuals represent their knowledge in memory. Together, these findings tentatively elaborate particular sociogenetic contributions to individuals' thinking and acting, and relations between particular elements and phases of goal-directed activities and, hence, their impact on cognitive change (development).Arts, Education & Law Group, School of Education and Professional StudiesFull Tex

    Le desserrage des tiges est une complication frĂ©quente des plĂątres avec tiges transcorticales (TP) chez les grands animaux, nĂ©cessitant souvent leur retrait prĂ©maturĂ© avant la guĂ©rison des fractures. Les charges excessives centrĂ©es sur le cortex Ă  l’interface os-tige proximo-externe et disto-interne causent de l'ostĂ©olyse. En utilisant un modĂšle de veau nouveau-nĂ©, ce projet a Ă©valuĂ© un nouveau systĂšme de tige-manchon et anneau integrĂ© dans un plĂątre (PS) optimisĂ© pour rĂ©duire la contrainte pĂ©ri-implant et le stress Ă  l'interface os-implant. On a Ă©mis l'hypothĂšse que les PS se traduiraient par une ostĂ©olyse pĂ©ri-implant moindre par rapport aux TP. Dix veaux en bonne santĂ©, de 3 semaines d'Ăąge, ont Ă©tĂ© implantĂ©s avec les TP ou PS dans le mĂ©tacarpe droit, Ă  raison de 2 implants par veau. Les veaux ont Ă©tĂ© observĂ©s quotidiennement pour le confort et la boiterie et ont Ă©tĂ© euthanasiĂ©s Ă  28 jours. Les donnĂ©es recueillies comprenaient les radiographies Ă  la chirurgie et Ă  l'euthanasie et les mesures histomorphomĂ©triques de contact os-implant sur des Ă©chantillons non-dĂ©calcifiĂ©s avec les implants in situ. Les donnĂ©es ont Ă©tĂ© analysĂ©es en utilisant le test de Cochran-Mantel-Haenszel, une valeur de P <0,05 a Ă©tĂ© considĂ©rĂ©e comme significative. L'Ă©paisseur corticale Ă©tait plus importante pour les implants distaux que proximaux pour les deux groupes lors de la chirurgie (P = 0,03), mais Ă©tait similaire entre les groupes (P > 0,3). Les veaux avec TP ont dĂ©veloppĂ© une boiterie plus tĂŽt (au jour 21) que les veaux avec PS (P = 0,04). Histologiquement, il y avait plus de contact direct os-implant cortical pour les implants PS distaux que les implants TP (P = 0,04). La jonction mĂ©taphyso-diaphysaire osseuse oĂč les implants proximaux Ă©taient situĂ©s est impropre aux deux systĂšmes; chacun a un minimum de contact os-implant et de l'ostĂ©olyse extensive. Le systĂšme PS n'ayant pas causĂ© une ostĂ©olyse importante lorsque implantĂ©s dans l'os diaphysaire et peut-ĂȘtre une alternative convenable aux TP pour des fractures comminutives des membres distaux.Pin loosening is a common complication of transfixation pincasts (TP) in large animals, often necessitating premature removal before fracture healing. The excessive loads centered on the proximo-external and disto-internal cortices of the bone-pin interface cause osteolysis. Using a neonatal calf model, this project evaluated a novel pin-sleeve and ring cast system (PS) optimized to decrease peri-implant strain and evenly share stress at the bone-implant interface. It was hypothesized that PS would result in less peri-implant osteolysis compared to TP. Ten, 3-week-old, healthy calves were implanted with either TP or PS in the right metacarpus, 2 implants per calf. Calves were scored daily for lameness and were euthanized at day 28. Collected data included radiographs at surgery and euthanasia and histomorphometric measures of bone-implant contact on non-decalcified specimens with the implants in situ. Data was analyzed using Cochran-Mantel-Haenszel test; a P-value <.05 was considered significant. The cortical thickness was larger for distal implants than proximal implants for both groups at surgery (P = 0.03), but were similar between groups (P > 0.3). TP calves developed lameness sooner, at day 21, than PS calves (P = 0.04). Histologically, there was more direct cortical bone-implant contact for PS distal implants than TP implants (P = 0.04). The metaphyseal-diaphyseal junction where the proximal implants were situated is unsuitable bone for either system; each had minimal bone-implant contact and extensive osteolysis. The PS system did not cause significant osteolysis when instrumented in diaphyseal bone and is a suitable alternative to TP for comminuted distal limb fractures

    This study surveyed university clinic directors of audiology and speech-language pathology programs throughout the United States, and identified the content and risk management (RM) practices embedded into graduate curricula. One hundred and two (102) respondents provided information, via an electronic survey, about their campus and departmental RM practices. More than half of the programs reported embedding RM concepts into at least one graduate course yet only slightly above half of the programs assessed students’ RM knowledge. Pre-professional students were most often trained in protecting patient’s privacy and fire drills. Approximately one-third participated in university-wide programs, and 11 of the 102 programs reported a freestanding RM committee. In contrast, the clinic directors reported frequent RM monitoring activities, including yearly updates to policy and procedure manuals, equipment and documentation audits, and monitoring of fire drill and in-service attendance records. University clinics are only somewhat invested in RM topics and pedagogy. Thus, pre-professional students may not be fully informed about RM in work settings. University clinics, American Speech-Language-Hearing Association and the American Academy of Audiology are encouraged to further evaluate the content and breadth of candidates’ knowledge and experiences to ensure that RM coursework and resources address this contemporary and critical topic

    Instrumental swallowing assessment in adults in residential aged care homes : Practice patterns and opportunities

    Objective To describe practice patterns in the use of instrumental swallowing assessment (ISA) for older adults in residential aged care homes (RACHs). Methods A retrospective audit of medical records of residents living in RACHs in Melbourne, Australia to extract data on speech-language pathologist (SLP) involvement, indications for ISA and ISA practice patterns. Results Medical files of 323 residents across four Melbourne facilities were reviewed. 36% (n = 115) of residents were referred to SLP for swallowing assessment. Referral to SLP was related to length of stay (U = 7393.00, p < 0.001), dementia status (χ2[1] = 7.06, p = 0.008), texture modification (χ2[1] = 93.34, p < 0.001) and an existing dysphagia diagnosis (χ2[1] = 112.89, p < 0.001). There were no referrals for ISA and no instances of ISA being used. Among 115 residents who were referred to SLP for swallowing assessment, there were 33 instances where ISA might be clinically relevant according to ISA indicators. Conclusions Instrumental swallowing assessment is not being used for the management of swallowing in RACHs in Australia despite a clinical need for ISA and a potential role for ISA to improve swallowing care quality. Lack of timely ISA may fail to meet the complex health-care needs of older adults living with dysphagia in RACHs, increasing their vulnerability to complications of dysphagia and its management

    Local food systems: concepts, impacts, and issues

    Consumer demand for food that is locally produced,marketed, and consumed is generating increased interest in local food throughout the United States. As interest grows, so do questions about what constitutes local food and what characterizes local food systems. What Is the Issue? This study provides a comprehensive literature-review-based overview of the current understanding of local food systems, including: alternative defi nitions; estimates of market size and reach; descriptions of the characteristics of local food consumers and producers; and an examination of early evidence on the economic and health impacts of such systems. What Did the Study Find? There is no generally accepted definition of “local” food. Though “local” has a geographic connotation, there is no consensus on a definition in terms of the distance between production and consumption. Definitions related to geographic distance between production and sales vary by regions, companies, consumers, and local food markets. According to the definition adopted by the U.S. Congress in the 2008 Food, Conservation, and Energy Act,the total distance that a product can be transported and still be considered a “locally or regionally produced agricultural food product” is less than 400 miles from its origin, or within the State in which it is produced. Definitions based on market arrangements, including direct-to-consumer arrangements such as regional farmers’ markets, or direct-to-retail/foodservice arrangements such as farm sales to schools, are well-recognized categories and are used in this report to provide statistics on the market development of local foods. Local food markets account for a small but growing share of total U.S. agricultural sales. ‱ Direct-to-consumer marketing amounted to 1.2billionincurrentdollarsalesin2007,accordingtothe2007CensusofAgriculture,comparedwith1.2 billion in current dollar sales in 2007, according to the 2007 Census of Agriculture, compared with 551 million in 1997. ‱ Direct-to-consumer sales accounted for 0.4 percent of total agricultural sales in 2007, up from 0.3 percent in 1997. If nonedible products are excluded from total agricultural sales, direct-to consumer sales accounted for 0.8 percent of agricultural sales in 2007. ‱ The number of farmers’ markets rose to 5,274 in 2009, up from 2,756 in 1998 and 1,755 in 1994, according to USDA’s Agricultural Marketing Service. ‱ In 2005, there were 1,144 community-supported agriculture organizations, up from 400 in 2001 and 2 in 1986, according to a study by the National Center for Appropriate Technology. In early 2010, estimates exceeded 1,400, but the number could be much larger. ‱ The number of farm to school programs, which use local farms as food suppliers for school meals programs and promote relationships between schools and farms, increased to 2,095 in 2009, up from 400 in 2004 and 2 in the 1996-97 school year, according to the National Farm to School Network. Data from the 2005 School Nutrition and Dietary Assessment Survey, sponsored by USDA’s Food and Nutrition Service, showed that 14 percent of school districts participated in Farm to School programs, and 16 percent reported having guidelines for purchasing locally grown produce. Production of locally marketed food is more likely to occur on small farms located in or near metropolitan counties. Local food markets typically involve small farmers, heterogeneous products, and short supply chains in which farmers also perform marketing functions, including storage, packaging, transportation, distribution, and advertising. According to the 2007 U.S. Census of Agriculture, most farms that sell directly to consumers are small farms with less than 50,000intotalfarmsales,locatedinurbancorridorsoftheNortheastandtheWestCoast.In2007,direct−to−consumersalesaccountedforalargershareofsalesforsmallfarms,asdefinedabove,thanformedium−sizedfarms(totalfarmsalesof50,000 in total farm sales, located in urban corridors of the Northeast and the West Coast. In 2007, direct-to-consumer sales accounted for a larger share of sales for small farms, as defi ned above, than for medium-sized farms (total farm sales of 50,000 to 499,999)andlargefarms(totalfarmsalesof499,999) and large farms (total farm sales of 500,000 or more). Produce farms engaged in local marketing made 56 percent of total agricultural direct sales to consumers, while accounting for 26 percent of all farms engaged in direct-to-consumer marketing. Direct-to-consumer sales are higher for the farms engaged in other entrepreneurial activities, such as organic production, tourism, and customwork (planting, plowing, harvesting, etc. for others), than for other farms. In 2007, direct sales by all U.S. farms surpassed customwork to become the leading on-farm entrepreneurial activity in terms of farm household participation. Barriers to local food-market entry and expansion include: capacity constraints for small farms and lack of distribution systems for moving local food into mainstream markets; limited research, education, and training for marketing local food; and uncertainties related to regulations that may affect local food production, such as food safety requirements. Consumers who value high-quality foods produced with low environmental impact are willing to pay more for locally produced food. Several studies have explored consumer preferences for locally produced food. Motives for “buying local” include perceived quality and freshness of local food and support for the local economy. Consumers who are willing to pay higher prices for locally produced foods place importance on product quality, nutritional value, methods of raising a product and those methods’ effects on the environment, and support for local farmers. Federal, State, and local government programs increasingly support local food systems. Many existing government programs and policies support local food initiatives, and the number of such programs is growing. Federal policies have grown over time to include the Community Food Project Grants Program, the WIC Farmers’ Market Nutrition Program, Senior Farmers’ Market Nutrition Program, Federal State Marketing Improvement Program, National Farmers’ Market Promotion Program, Specialty Crop Block Grant Program, and the Community Facilities Program. State and local policies include those related to farm-to-institution procurement, promotion of local food markets, incentives for low-income consumers to shop at farmers’ markets, and creation of State Food Policy Councils to discuss opportunities and potential impact of government intervention. (WIC is the acronym for the Special Supplemental Nutrition Program for Women, Infants, and Children). As of early 2010, there were few studies on the impact of local food markets on economic development, health, or environmental quality. ‱ Empirical research has found that expanding local food systems in a community can increase employment and income in that community. ‱ Empirical evidence is insuffi cient to determine whether local food availability improves diet quality or food security. ‱ Life-cycle assessments—analyses of energy use at all stages of the food system including consumption and disposal—suggest that localization can but does not necessarily reduce energy use or greenhouse gas emissions. How Was the Study Conducted? Existing analyses of local food markets by universities, government agencies, national nonprofit organizations, and others of local food markets were synthesized to evaluate the definition of local foods and the effects of local food systems on economic development, health and nutrition, food security, and energy use and greenhouse gas emissions. The report’s content relies on data collected through the 2007 Census of Agriculture, as well as other surveys by USDA’s Agricultural Marketing Service, the National Farm to School Network, university extension departments, and others, to provide a comprehensive picture of types of local food markets, their characteristics, and their importance over time.Local food systems; farmers’ markets; direct-to-consumer marketing; direct-to-retail/foodservice marketing; community supported agriculture; farm to school programs; Farmers’ Market Promotion Program; food miles; ERS; USDA

    This comprehensive overview of local food systems explores alternative definitions of local food, estimates market size and reach, describes the characteristics of local consumers and producers, and examines early indications of the economic and health impacts of local food systems. There is no consensus on a definition of “local” or “local food systems” in terms of the geographic distance between production and consumption. But defining “local” based on marketing arrangements, such as farmers selling directly to consumers at regional farmers’ markets or to schools, is well recognized. Statistics suggest that local food markets account for a small, but growing, share of U.S. agricultural production. For smaller farms, direct marketing to consumers accounts for a higher percentage of their sales than for larger farms. Findings are mixed on the impact of local food systems on local economic development and better nutrition levels among consumers, and sparse literature is so far inconclusive about whether localization reduces energy use or greenhouse gas emissions.local food systems, farmers’ markets, direct-to-consumer marketing, direct-to-retail/ foodservice marketing, community supported agriculture, farm to school programs, Farmers’ Market Promotion Program, food miles, Community/Rural/Urban Development,
