Properties comparison of Injected and SLS material

Most of the plastic injection companies are focused in the production of some products with a high exigency standard levels. That is why, to compete and gain some market share in front of the concurrency of companies from other countries, they need to be able to introduce new rapid prototyping techniques and product development.

Produktentwicklung von Druckgussteilen

Die Produktentwicklung von Druckgussteilen kann flexibel, wirtschaftlich und schnell durch die Herstellung von RP-Unikaten und Metallabgüssen aus Keramikschalen realisiert werden. Dieser Weg eignet sich vor allem für komplexe Bauteile und macht eine Produkterprobung mit qualitativ deutlich verbesserter Aussagekraft trotz reduzierter Entwicklungskosten möglich. In Abgrenzung zum Sandguss, muss die Konstruktion der Bauteile nicht verändert werden. 
Durch eine gezielte Wärmebehandlung wird die Vergleichbarkeit der mechanischen Eigenschaften von Prototypen zu späteren Serienteilen möglich. Technisch sinnvolle Änderungen sind leicht und flexibel realisierbar, da werkzeuglos gefertigt wird. Für unerreichbare Hohlräume und Hinterschnitte kann in diesem Verfahren mit Keramikkernen als Einleger gearbeitet werden. Auch diese Kerne können werkzeuglos hergestellt werden. Ein Verzicht auf technisch Sinnvolles aus Kostengründen ist damit hinfällig.
In der Konstruktion ergeben sich neue Freiheitsgrade, so dass Ziele im Leichtbau, die Einsparung von Verbindungstechnik oder die erhöhte Materialeffizienz realisierbar werden. Die so entwickelten Bauteile sind insgesamt qualitativ hochwertiger und bilden die technischen Anforderungen bestmöglich ab. Damit kann die für die Erprobung benötigte Zahl der Prototypen verringert werden. 
Je komplexer die Geometrie der Bauteile, je stärker kommen die beschriebenen Effekte zum Tragen. Diese Aussage gilt für die Produktentwicklung und für Kleinserien, die herkömmlich zu teuer und zu schwer im Druckguss oder Schmiedeverfahren produziert werden

Semantic Methods for Intelligent Distributed Design Environments

Continuous advancements in technology have led to increasingly comprehensive and distributed product development processes while in pursuit of improved products at reduced costs. Information associated with these products is ever changing, and structured frameworks have become integral to managing such fluid information. Ontologies and the Semantic Web have emerged as key alternatives for capturing product knowledge in both a human-readable and computable manner. The primary and conclusive focus of this research is to characterize relationships formed within methodically developed distributed design knowledge frameworks to ultimately provide a pervasive real-time awareness in distributed design processes. Utilizing formal logics in the form of the Semantic Web’s OWL and SWRL, causal relationships are expressed to guide and facilitate knowledge acquisition as well as identify contradictions between knowledge in a knowledge base. To improve the efficiency during both the development and operational phases of these “intelligent” frameworks, a semantic relatedness algorithm is designed specifically to identify and rank underlying relationships within product development processes. After reviewing several semantic relatedness measures, three techniques, including a novel meronomic technique, are combined to create AIERO, the Algorithm for Identifying Engineering Relationships in Ontologies. In determining its applicability and accuracy, AIERO was applied to three separate, independently developed ontologies. The results indicate AIERO is capable of consistently returning relatedness values one would intuitively expect. To assess the effectiveness of AIERO in exposing underlying causal relationships across product development platforms, a case study involving the development of an industry-inspired printed circuit board (PCB) is presented. After instantiating the PCB knowledge base and developing an initial set of rules, FIDOE, the Framework for Intelligent Distributed Ontologies in Engineering, was employed to identify additional causal relationships through extensional relatedness measurements. In a conclusive PCB redesign, the resulting “intelligent” framework demonstrates its ability to pass values between instances, identify inconsistencies amongst instantiated knowledge, and identify conflicting values within product development frameworks. The results highlight how the introduced semantic methods can enhance the current knowledge acquisition, knowledge management, and knowledge validation capabilities of traditional knowledge bases.

The Use of a Vaginal Conductivity Probe to Influence Calf Sex Ratio via Altered Insemination Time

One hundred eighty-nine mixed breed beef heifers from 13 consignors enrolled in the MACEP heifer development project were utilized in this study. Heifers were synchronized by feeding 0.5 mg melengestrol acetate (MGA) per head per day for 14 days followed by an injection of prostaglandin F2a (PGF2a; 25 mg Lutalyse®) 17 days after the last MGA feeding. Each heifer was fitted with a Heatwatch® transmitter on the morning of PGF2a administration to facilitate detection of estrus. Vaginal conductivity measurements were taken using an Ovatec® probe every 12 hours for 96 hours beginning at the time of PGF2a injection. Heifers randomly assigned to produce a female calf were inseminated near the onset of estrus (as indicated by probe values of £ 55 on the decline). Heifers randomly assigned to produce a male calf were inseminated approximately 24 hours after the onset of estrus (as indicated by probe values of ³ 60 on the incline). All heifers not inseminated by 96 hours after PGF2a were mass inseminated in an attempt to impregnate as many heifers as possible. Heifers that were diagnosed as pregnant as a result of the artificial insemination were subjected to ultrasonography for fetal sex determination. Only 70 of the 189 heifers (37.0%) exhibited estrus according to Heatwatch® and incidence of estrus was influenced by heifer average daily gain, reproductive tract score, and disposition score. Heifers receiving a disposition score of 3 (78.7) had a higher (P<.05) probe reading at AI than those receiving a disposition score of 1 or 2 (70.8 and 72.5, respectively). Heifers with probe readings at insemination of 80 - 84 and > 84 had lower (P<.05) pregnancy rates to AI (13.6 and 0.0%, respectively) than heifers with probe readings in the ranges of < 60, 60 - 64, 65 - 69, 70 - 74, and 75 - 79 (35.7, 40.9, 31.4, 35.3, and 26.9% respectively). Heifers that were bred when probe values were increasing had a lower (P<.05) percentage of male fetuses (34.4%) than those bred during a period of decreasing probe values (69.2% male fetuses). These results demonstrate that a vaginal conductivity probe may be a useful tool to determine an insemination time that could potentially alter calf sex ratio.

The role of brand marketing in snowboarding: A comparative study of Switzerland and New Zealand

Introduction: Brands play an essential role in the organizational structure of snowboarding by sponsoring athletes, arranging events, contributing to product development and developing long-term partnerships with other key actors. However, the specialities of their role in scene sports, such as creating identities, networking and brand marketing strategies, have not been extensively researched. This study aims to provide an analysis of the function of brands within the snowboarding subculture by comparing how the sport is organized in Switzerland and New Zealand. Sociological theories of subcultures (Hitzler & Niederbacher, 2010) and social networks (Stegbauer, 2008) are used to defi ne the structures of the sport, whereas marketing and branding theories (Adjouri & Stastny, 2006) help to understand the role of the brands. Snowboarding will be defi ned as an alternative sports subculture based on characteristics such as aesthetics, adventure and new resources of performance (Schwier, 2006). Such a defi nition also begs for a novel form of analyzing its organization. Unlike more conventional structures, the organization of snowboarding allows a variety of actors to get involved in leading the sport. By portraying and encouraging differentiated identities and lifestyles, athletes provide a space for other actors to fi nd their place within the sport (Wheaton, 2005). According to Stegbauers network theory, individual actors are able to obtain high positions and defi ne their identity depending on their ties to actors and networks within the subculture (Stegbauer, 2008). For example, social capital, contacts within the sport and insider knowledge on subculture-related information enable actors to get closer to the core (Hitzler & Niederbacher, 2010). Actors who do not have close networks and allies within the subculture are less likely to engage successfully in the culture, whether as an individual or as a commercial actor (Thorpe, 2011). This study focuses on the organizational structure of snowboarding by comparing the development of the sport in Switzerland and New Zealand. An analysis of snowboarding in two nations with diverse cultures and economic systems allows a further defi nition of the structural organization of the sport and explains how brands play an important role in the sport. Methods: The structural organization of the sport will be analyzed through an ethnographic approach, using participant observation at various leading events in Switzerland (Freestyle.ch, European Open) and New Zealand (World Heli Challenge, New Zealand Open, New Zealand Winter Games). The data is analyzed using grounded theory (Glaser & Strauss 1967) and gives an overview of the actors that are playing an important role in the local development of snowboarding. Participant observation was also used as a tool to get inside the sport culture and opened up the possibility to make over 40 semi-structured qualitative expert interviews with international core actors from 11 countries. Obtaining access to one actor as a partner early on helped to get inside the local sport culture. The ‘snowball effect’ allowed the researcher to acquire access, build trust and conduct interviews with experts within the core scene. All the interviewed actors have a direct infl uence on the sport in one or both countries, which permit a cross-analysis. The data of the interviews was evaluated through content analysis (Mayring 2010). The two methods together provided suffi cient data to analyze the organizational structure and discuss the role of brand marketing within snowboarding. Results: An actors mapping by means of a center-periphery framework has identifi ed fi ve main core groups: athletes, media representatives, brand-marketing managers, resort managers and event organizers. In both countries the same grouping of actors were found. Despite possessing different and frequently multiple roles and responsibilities, core actors appear to have a strong common identifi cation as ‘snowboarders’, are considered to be part of the organizational elite of the sport and tend to advocate similar goals. The author has found that brands in Switzerland tend to have a larger impact on the broader snowboarding culture due to a number of factors discussed below. Due to a larger amount of snowboarders and stronger economic power in Europe, snowboarders are making attempts to differentiate themselves from other winter sports, while competing with each other to develop niche markets. In New Zealand, on the other hand, the smaller market enables more cooperation and mutual respect within snowboarders. Further they are more closely linked to other winter sports and are satisfi ed with being lumped together. In both countries, brands have taken up the role of supporting young athletes, organizing competitions and feeding media with subculture-related content. Brands build their image and identity through the collaboration with particular athletes who can represent the values of the brand. Local and global communities with similar lifestyles and interests are being built around brands that share a common vision of the sport. The dominance of brands in snowboarding has enabled them with the power to organize and rule the sport through its fan base and supporters. Brands were defi ned by interviewees as independent institutions led by insiders who know the codes and symbols of the sport and were given trust and credibility. The brands identify themselves as the engines of the sport by providing the equipment, opportunities for athletes to get exposure, allowing media to get exclusive information on activities, events and sport-related stories. Differences between the two countries are more related to the economic system. While Switzerland is well integrated in the broader European market, New Zealand’s geographical isolation and close proximity to Australia tends to limit its market. Further, due to different cultural lifestyles, access to resorts and seasonal restrictions, to name a few, the amount of people practicing winter sports in New Zealand is much smaller than in Switzerland. However, this also presents numerous advantages. For example, the short southern hemisphere winter season in New Zealand enables them to attract international sports athletes, brands and representatives in a period when Europe and North America is in summer. Further, the unique snow conditions in New Zealand and majestic landscape is popular for attracting world renowned photo- and cinematographers. Another advantage is the less populated network as it provides the opportunity for individuals to gain easier access to the core of the sport, obtain diverse positions and form a unique identity and market. In Switzerland, on the other hand, the snowboarding network is dense with few positions available for the taking. Homegrown brands with core recognition are found in both countries. It was found that the Swiss brands tend to have a larger impact on the market, whereas in New Zealand, the sport is more dependent on import products by foreign brands. Further, athletes, events and resorts in New Zealand are often dependent on large brand sponsorships from abroad such as from brand headquarters in the Unites States. Thus, due to its location in the centre of Europe, Swiss brands can take advantage of brands which are closer in proximity and culture to sponsor athletes and events. In terms of media coverage, winter sports in New Zealand tend to have a minor coverage and tradition in local mass media, which leads to less exposure, recognition and investment into the sport. This is also related to how snowboarding is more integrated into other winter sports in New Zealand. Another difference is the accessibility of the ski resort by the population. While in Switzerland the resorts are mostly being visited by day-travelers, ‘weekend warriors’ and holiday makers, the location of the resorts in New Zealand make it diffi cult to visit for one day. This is in part due to the fact that Swiss ski resorts and villages are usually the same location and are accessible through public transportation, while the ski resorts in New Zealand have been built separately from the villages. Further, the villages have not been built to accommodate to high tourist arrivals. Thus, accommodation and food facilities are limited and there is a lack of public transportation to the resorts. Discussion: The fi ndings show that networks and social relations combined with specifi c knowledge on scene-related attributes are crucial in obtaining opportunities within the sport. Partnerships as well as competition between these different actors are necessary for core acceptance, peer credibility and successful commercial interests. Brands need to maintain effective marketing strategies and identities which incorporate subcultural forms of behavior and communication. In order to sustain credibility from its fans, athletes and other snowboarding actors, brands need to maintain their insider status through social networks and commercial branding strategies. The interaction between all actors is a reciprocated process, where social capital, networks and identities are being shared. While the overall structure of snowboard subcultures in Europe and New Zealand are similar, there are some distinct characteristics which make each one unique. References Adjouri, N. & Stastny, P.

The role of commercial actors in snowboarding

Commercial actors play an essential role in the organisational structure of snowboarding by sponsoring athletes, arranging events, contributing to product development and developing long-term partnerships with other key actors. However, the particularities of their role in the alternative sports cultures which are related to brand marketing strategies have not been extensively researched. Based on Hitzler and Niederbachers (2010) framework of social scenes, Stegbauers (2008) social network and Adjouri and Stastnys (2006) branding theories, analysis is carried out using an ethnographic approach. This includes participant observation of relevant events and semi-structured interviews with over forty key actors of the sport to examine the roles and activities of core actors within snowboarding. The findings reveal that brands have gained an important position within the scene; where they can build partnerships with other core and periphery actors in order to market particularly identities, lifestyles and products. This contributes to the development of a sport which is dependent on brands for its continuity. By using promotional strategies of sponsoring athletes, organising events and feeding media with scene-related content, the aesthetical values of the snowboarding sport are communicated and transferred, while ensuring exposure of the brand’s image and lifestyle. Social contacts as well as knowledge on particularities of the sport allow the commercial actors to gain an influential position and identity within the snowboarding core culture.

Linking Applied Ethnobotany to Social Learning: A Participatory Tool for the Promotion of Indigenous Plants Use in Matutuíne, Southern Mozambique

In its search for pathways towards a more sustainable management of natural resources, development oriented research increasingly faces the challenge to develop new concepts and tools based on transdisciplinarity. Transdisciplinarity can, in terms of an idealized goal, be defined as a research approach that identifies and solves problems not only independently of disciplinary boundaries, but also including the knowledge and perceptions of non-scientific actors in a participatory process. In Mozambique, the Centre for Development and Environment (Berne, Switzerland), in partnership with Impacto and Helvetas (Maputo, Mozambique), has elaborated a new transdisciplinary tool to identify indigenous plants with a potential for commercialization. The tool combines methods from applied ethnobotany with participatory research in a social learning process. This approach was devised to support a development project aimed at creating alternative sources of income for rural communities of Matutuíne district, Southern Mozambique, while reducing the pressure on the natural environment. The methodology, which has been applied and tested, is innovative in that it combines important data collection through participatory research with a social learning process involving both local and external actors. This mutual learning process provides a space for complementary forms of knowledge to meet, eventually leading to the adoption of an integrated approach to natural resource management with an understanding of its ecological, socio-economic and cultural aspects; local stakeholders are included in the identification of potentials for sustainable development. Sustainable development itself, as a normative concept, can only be defined through social learning and consensus building between the local and external stakeholders.

AN OCCUPATIONAL INJURY MANAGEMENT INFORMATION SYSTEM FOR THE UNIVERSITY OF TEXAS HEALTH SCIENCE CENTER AT HOUSTON

The purpose of this research and development project was to develop a method, a design, and a prototype for gathering, managing, and presenting data about occupational injuries.^ State-of-the-art systems analysis and design methodologies were applied to the long standing problem in the field of occupational safety and health of processing workplace injuries data into information for safety and health program management as well as preliminary research about accident etiologies. The top-down planning and bottom-up implementation approach was utilized to design an occupational injury management information system. A description of a managerial control system and a comprehensive system to integrate safety and health program management was provided.^ The project showed that current management information systems (MIS) theory and methods could be applied successfully to the problems of employee injury surveillance and control program performance evaluation. The model developed in the first section was applied at The University of Texas Health Science Center at Houston (UTHSCH).^ The system in current use at the UTHSCH was described and evaluated, and a prototype was developed for the UTHSCH. The prototype incorporated procedures for collecting, storing, and retrieving records of injuries and the procedures necessary to prepare reports, analyses, and graphics for management in the Health Science Center. Examples of reports, analyses, and graphics presenting UTHSCH and computer generated data were included.^ It was concluded that a pilot test of this MIS should be implemented and evaluated at the UTHSCH and other settings. Further research and development efforts for the total safety and health management information systems, control systems, component systems, and variable selection should be pursued. Finally, integration of the safety and health program MIS into the comprehensive or executive MIS was recommended. ^

A MANAGEMENT INFORMATION SYSTEM AND EVALUATION SCHEME FOR THE UNIVERSITY OF TEXAS EMPLOYEE ASSISTANCE PROGRAMS

Early Employee Assistance Programs (EAPs) had their origin in humanitarian motives, and there was little concern for their cost/benefit ratios; however, as some programs began accumulating data and analyzing it over time, even with single variables such as absenteeism, it became apparent that the humanitarian reasons for a program could be reinforced by cost savings particularly when the existence of the program was subject to justification.^ Today there is general agreement that cost/benefit analyses of EAPs are desirable, but the specific models for such analyses, particularly those making use of sophisticated but simple computer based data management systems, are few.^ The purpose of this research and development project was to develop a method, a design, and a prototype for gathering managing and presenting information about EAPS. This scheme provides information retrieval and analyses relevant to such aspects of EAP operations as: (1) EAP personnel activities, (2) Supervisory training effectiveness, (3) Client population demographics, (4) Assessment and Referral Effectiveness, (5) Treatment network efficacy, (6) Economic worth of the EAP.^ This scheme has been implemented and made operational at The University of Texas Employee Assistance Programs for more than three years.^ Application of the scheme in the various programs has defined certain variables which remained necessary in all programs. Depending on the degree of aggressiveness for data acquisition maintained by program personnel, other program specific variables are also defined. ^

Cambios en la estructura económica social y conflictos sociales en el noroeste del Chubut 1990-2005

Buscamos avanzar en el conocimiento sobre cómo se desarrolla el movimiento de la sociedad argentina en su conjunto, analizado desde un caso particular que es el noreste del Chubut en el período que va desde la imposición de la hegemonía del capital financiero en 1989-1990 hasta el año 2005. Se pretende en esta tesis entender y conceptualizar en términos científicos cómo se mueve esa sociedad, de qué son expresión cada uno de sus conflictos, qué expresan los distintos sectores que se movilizan, qué expresan los cambios estructurales que se desarrollan, etc. Desde esta perspectiva nos interesa específicamente poder aportar al debate sobre cuáles son las opciones de plantear un proyecto alternativo de desarrollo para la provincia, la región y el país. Dentro del tema general de buscar comprender el movimiento de la sociedad, realizamos un abordaje de la realidad desde la utilización de un conocimiento acumulado y desde un recorte de esa realidad. Ese recorte lo realizamos a dos niveles. En primer lugar en términos espaciales: tomamos como base una región que denominamos el noreste de Chubut. Recortamos de la provincia del Chubut al área que tuvo el mayor crecimiento vinculado a los programas de polos de desarrollo durante las décadas del '60, '70 y parte del '80. La misma está delimitada por los actuales departamentos de Rawson y Biedma, de acuerdo a la división administrativa que toma la provincia desde 1957. En segundo lugar realizamos un recorte en términos temporales: abordamos como objeto de estudio al movimiento de la sociedad en esa región durante el período que va de 1989-1990 hasta el 2005. Consideramos que tomar este período nos permite observar el proceso de cambios que se generan con la realización de la hegemonía del capital financiero y el proceso de protestas, luchas y conflictos sociales que en el marco de estos cambios se desarrollan en la sociedad. La decisión de estudiar hasta el 2005 parte de considerar relevante comprender cómo continua el proceso después del 2001-2002. En esos años se produce la recuperación de la economía nacional, con un gran impulso para la región, lo cual genera el interés de poder precisar de qué se trata esta 'recuperación' y si estamos ante un movimiento orgánico o coyuntural de la economía. El período también nos permitió profundizar en el debate de las relaciones de fuerzas políticas, al hacer observable el período en que la burguesía logra recuperar la representación institucional como expresión legítima de la sociedad y consigue frenar la protesta social

Financiamiento y comercialización de la agricultura familiar en el Gran La Plata. Estudio en el marco de un proyecto de Desarrollo Territorial

En la actualidad, la agricultura familiar ha tomado visibilidad tanto en trabajos académicos como en el diseño de políticas públicas. Si bien se reconocen características propias que la diferencian de la producción empresarial, se presentan de acuerdo al tipo de producción y el territorio donde se inserta, particularidades que permiten definirlas y analizarlas. En el caso de la producción hortiflorícola familiar que abastece de productos frescos a los grandes centros urbanos, la especificidad del sistema productivo intensivo en trabajo, las tecnologías utilizadas, las características de los productos obtenidos, su comercialización y localización, difiere sustancialmente de otros sistemas productivos del país. De acuerdo a diagnósticos elaborados por INTA (2004) y otros trabajos cualitativos en el periurbano bonaerense, las dificultades que afrontan estas unidades familiares son de carácter múltiple. Entre las más importantes se mencionan la subordinación en la cadena comercial y acceso al financiamiento. Este trabajo busca dar cuenta de un proyecto de desarrollo territorial en la región periurbana del Gran La Plata, en el cual se aborda desde una perspectiva integral aspectos de financiamiento y comercialización a productores familiares. El mismo se focaliza en 30 productores familiares de La Plata y Berazategui pertenecientes al proyecto "Banco Social" implementado desde la Facultad de Ciencias Agrarias y Forestales de la UNLP; avanzando en un análisis respecto al acceso al financiamiento y las estrategias comerciales llevadas por los productores familiares bajo estudio
