No full textDieser Praxisbericht beschreibt verschiedene Einsatzmöglichkeiten eines Hundes als Medium in der tiergestützten logopädischen Therapie. Das therapeutische Vorgehen wird dabei in Bezug zum integrativen Ansatz gesetzt. Der Schwerpunkt dieses Praxisberichts liegt auf der Arbeit mit spät sprechenden Kindern (Late Talker), die anhand eines Fallbeispiels näher betrachtet wird. Hierbei kann ein Hund unter Anleitung der Therapeutin mehrere Funktionen erfüllen: er dient als sozialer Katalysator beim Beziehungs- und Vertrauensaufbau, als Motivator für die Therapie und als Sprechanlass.This practical experience report deals with different possibilities of using a dog as a medium in animal assisted speech language therapy. The therapeutic approach gets related to Integrative Therapy. This practical report focusses on the therapy of late talking toddlers (Late Talker) and is presented in form of a case study. Under guidance of the therapist the dog can fulfill several functions in the therapy of a Late Talker: he serves as a social promoter while establishing an relationship with and trust in the therapist at the beginning of a therapy, supports the motivation of the child during the therapy and also gives reasons to talk about.https://www.fpi-publikation.de/gruene-texte/30-2017-reitz-c-tiergestuetzte-sprachfoerderung-logopaedische-praxis-spaet-sprechende-kinder/peerReviewedpublishedVersio
Integrated simulations of Mars flights on the ISS
No full textThe human quest towards the exploration of the solar system and beyond will likely continue to grow in the next few decades. Many scientific and technological challenges still need to be approached and solved to enable long deep space human exploration. Once answers to these challenges are available, they will be integrated in the flight plans as ad hoc operational strategies.
For the solution of specific scientific and technological problems, experiments using ground analogues may provide optimal responses; however, only the International Space Station (ISS) can play the role of integrated analogue, where the impact of micro-gravity, radiation, living and psychological conditions that astronauts will face during a deep space cruise, can be mimicked at the same time, in part or in whole.
Today the ISS is a unique technological and scientific platform that enables researchers from all over the world to work on innovative experiments that could not be performed anywhere else. However, it is conceivable to use the deep space analogue features of the ISS to perform integrated tests of those operational strategies needed to allow for deep space voyages, towards a potential final integrated in-space test of the entire voyage to Mars, with a fidelity as high as achievable. This utilization strategy for the ISS would help focusing research and technology on open questions for deep space exploration, also enabling further tests of the journey to Mars using other advanced platforms that will be available on Moon orbit or surface in the near future. It will also provide the ISS with the rank of “springboard” towards deep space for the general public, increasing the awareness for human space exploration. In this paper we present the ISS4Mars idea, underlining its major goals and challenges
Modification and elaboration of the original Smuts (2011) explanatory intention to quit structural model and empirical testing of the modified and elaborated Reitz model
No full textThesis (MCom)--Stellenbosch University, 2019.ENGLISH SUMMARY : Today’s business environment has become very competitive and the retention of skilled, high-performing employees has therefore also become a major concern to managers worldwide. It has become crucial to recruit talented, smart and capable people and also to keep these top talent employees out of the hands of other companies.
Organisations invest large amounts of money time and energy each year to recruit, select and develop talented employees. Organisations also need to invest resources to retain these talented employees. At the same time, however, they also find themselves reluctant to spend too much money on talented employees, because of the possibility of losing their best employees to competitors.
Voluntary turnover of employees occurs when an employee voluntarily leaves his/her job and has to be replaced by someone else (Samuel & Chipunza, 2009). Retention, represents an integrated set of interventions developed by organisations aimed at retaining talented employees and rooted in the reasons for the intention to quit under their (high-performing) employees. Thus, the primary goal of interventions aimed at retaining talented employees is to try and minimise the outflow of high-performing employees. The loss of its high-performing employees holds serious have negative consequences for organisations’ productivity and service delivery.
The strength of the intention to quit varies across employees. The differences in the strength of the turnover intention across employees is not the outcome of a chance phenomenon, but rather the result of specific latent variables that define the employee and his/her working environment. It is consequently important to validly understand the identity of these determining variables.
Smuts (2011) argued that the psychological mechanism that regulates the performance level that line managers achieve on the talent management competencies affect the strength of their subordinates’ turnover intention, is more intricate than is acknowledged by the Oehley (2007) structural model. Oehley (2007) has developed the first integrated structural model aimed at describing the psychological mechanism that regulates employees’ intention to quit. Smuts (2011) has formally acknowledged the importance of cumulative research by proposing extensions to the Oehley (2007) intention to quit model, but, however, failed to test her full model. The strength of employees’ intention to quit is complexly determined.
A need therefore exists to re-attempt to fit the comprehensive Smuts (2011) model that she originally proposed. Therefore, the primary aim of the current study is to expand (and to modify if necessary) the original Smuts (2010) explanatory intention to quit structural model and to empirically test the modified and expanded model. The present study further elaborated and integrated the work done by Oehley (2007), Smuts (2011) and Bezuidenhout (2013).
The overarching substantive research hypothesis was dissected into fifteen more detailed, path-specific substantive research hypotheses. The Reitz measurement model showed good fit (RMSEA=.02). The comprehensive LISREL Reitz intention to quit model showed reasonable fit according to the goodness of fit statistics (RMSEA=.063, p>.05). Support was found for one of the fifteen path-specific substantive hypotheses and partial support was obtained for nine of the fifteen path-specific substantive hypotheses.
Practical managerial implications are discussed. Recommendations for future research are made.AFRIKAANSE OPSOMMING : Vandag se besigheidsomgewing het baie mededingend geword en die behoud van geskoolde, hoog-presterende werknemers het dus ook wêreldwyd 'n groot bekommernis vir bestuurders geword. Dit het noodsaaklik geraak om talentvolle, slim en bevoegde mense te werf en ook om hierdie top talentvolle werknemers uit die hande van ander maatskappye te hou.
Organisasies spandeer jaarliks groot hoeveelhede finansiële en ander hulpbronne in 'n poging om talentvolle werknemers te lok, te ontwikkel en te behou, maar terselfdertyd vind hulle hulself ook huiwerig om té groot hoeveelhede geld aan talentvolle werknemers te spandeer, weens die moontlikheid om hulle beste werknemers te verloor aan mededingers.
Vrywillige omset van werknemers vind plaas wanneer 'n werknemer vrywillig sy/haar werk verlaat en deur iemand anders vervang moet word (Samuel & Chipunza, 2009). Behoud, verteenwoordig 'n geïntegreerde stel intervensies wat deur organisasies ontwikkel is, wat daarop gemik is om talentvolle werknemers te behou en wat gewortel is in die redes vir die voorneme onder hul (hoog-presterende) werknemers om hul werk te verlaat. Die primêre doel van behoud is dus om die verlies van hul bevoegde werknemers te voorkom, aangesien dit die produktiwiteit en dienslewering van die organisasie negatief kan beïnvloed.
Die sterkte van die voorneme om werk te verlaat wissel tussen werknemers. Die verskille in die sterkte van die omsetvoorneme oor werknemers is nie die gevolg van 'n ewekansige gebeurtenis nie, maar eerder die gevolg van sommige bepalende veranderlikes wat die werknemer en sy/haar werksomgewing karakteriseer. Dit is dus belangrik om die identiteit van hierdie bepalende veranderlikes geldig te verstaan.
Smuts (2011) het geargumenteer dat die sielkundige meganisme waardeur die vlak van bevoegdheid wat lynbestuurders op die talentbestuursbevoegdhede bereik, die sterkte van hul volgelinge se voorneme om op te hou werk affekteer, meer ingewikkeld is as wat die Oehley (2007) struktuele model erken. Oehley (2007) het 'n waardevolle verklarende model van werknemeromset-voorneme voorgestel. Smuts (2011) het die belangrikheid van kumulatiewe navorsing formeel erken deur uitbreidings aan die Oehley (2007) model aan te bring, maar het nie daarin geslaag om haar volle model te toets nie. Die sterkte van werknemers se voorneme om op te hou werk is kompleks gedetermineer.
Daar bestaan dus 'n behoefte om die omvattende Smuts (2011) model wat sy oorspronklik voorgestel het, weer te evalueer en te probeer pas. Daarom is die primêre doel van hierdie navorsingsinisiatief om die oorspronklike Smuts (2010) se verklarende werknemeromset-struktuele model aan te pas en uit te brei en om dan die uitgebreide model empiries te evalueer. Die huidige studie het ook verder uitgebrei en geïntegreer op die werk wat deur Oehley (2007), Smuts (2011) en Bezuidenhout (2013) gedoen is. Die huidige studie beoog dus om die verklarende Oehley - Smuts - Bezuidenhout - Reitz talentbestuursvaardigheidsmodel te toets.
Die oorkoepelende substantiewe navorsingshipotese is in vyftien meer gedetailleerde, baanspesifieke substantiewe navorsingshipoteses dissekteer. Die Reitz metings model het goeie pasgehalte getoon (RMSEA=.02). Die omvattende LISREL Reitz werknemeromset-voorneme model het volgens die pasgehalte statistieke redelike pasgehalte getoon (RMSEA=.063, p>.05). Steun is gevind vir een van die vyftien baanspesifieke substantiewe navorsingshipoteses en gedeeltelike steun is gevind vir nege van die vyftien baanspesifieke substantiewe navorsingshipoteses.
Praktiese bestuurs-implikasies word bespreek. Aanbevelings vir verdere navorsing word gemaak.Master

Writing a Landscape of Defeat:The Romans in Parthia
No full textThis chapter deals with Roman literary representations of Parthia as a ‘landscape of defeat’ during the principate. I investigate how Roman authors’ depictions of the spaces and landscape of Parthia relate to the traumatic military campaigns of the late republic (especially Crassus’s disastrous defeat at Carrhae) and to the uneasy diplomatic accommodation between the two superpowers during the early empire. I argue that by writing Parthia as a ‘landscape of defeat’, Roman authors show how established modes of understanding, conquering and controlling landscapes failed in Parthia. I focus on the literature of the principate, specifically on the period from Augustus’s Parthian treaty up to the renewed (and, for a short time, successful) attempts at conquering Parthia under the emperor Trajan. In the first section of this chapter, I argue that Roman authors reflect on military setbacks in Parthia by questioning Roman understanding of Parthian terrain, geography and ethnography
Origin of salt-enriched pore fluids in the northern Gulf of Mexico
No full textPore fluids from the Green Canyon Block in the northern Gulf of Mexico show distinct differences with respect to element concentrations and oxygen, hydrogen, and strontium isotope signatures. The shallowest of the three investigated sites (GC185 or Bush Hill at 540 m water depth) is interpreted as a seafloor piercing mud mound and the two deeper areas (GC415 East and West at 950 and 1050 m water depth) as gas vent and oil seep sites. All three locations accommodate near-surface gas hydrates and the sediment surface is populated with chemosynthetic communities. They are characterized by a distinct increase in salinity with depth. However, the origin of this increasing salinity is different for the GC415 sites and Bush Hill and the depth source of the fluids is considerably different for all sites. The more saline fluids of the GC415 sites result from the dissolution of halite by formation water from two different sources. The fluids of GC415 East have most likely a deeper origin (early Cenozoic or even Mesozoic) and experienced elevated temperatures leading to mineral/water reactions including mineral transformations (e.g. smectite to illite transformation) and dissolution (e.g. feldspar dissolution). This process is expressed by the heavier oxygen isotope values and distinct Li, Sr, and Ca enrichments. The fluids of GC415 West have a shallower origin which is expressed by a smaller enrichment in Li, Sr, and Ca and lighter oxygen isotopes. The fluids from Bush Hill are less saline and its fluid signature indicates intensive water/mineral interaction. Oxygen and hydrogen isotope values as well as Na/Cl and Br/Cl molar ratios suggest that the salt enrichment was caused by phase separation under sub-critical conditions. A simple heat flow model simulation suggests that sub-critical phase separation may have occurred at a depth of 1650 m at 350 °C
Caracterização reprodutiva de Dyckia ibiramensis Reitz, uma bromélia endêmica ao Alto Vale do Itajaí, SC
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Biológicas. Programa de Pós-Graduação em Biologia VegetalDyckia ibiramensis Reitz (Bromeliaceae) é uma espécie endêmica do município de Ibirama/SC, cuja distribuição se restringe a aproximadamente 4 km de extensão nas margens do Rio Itajaí do Norte. Desde 1992, consta na "Lista de Espécies da Flora Ameaçadas de Extinção" na categoria "Em perigo", e no ano de 2005, no Workshop "Revisão da Lista da Flora Brasileira Ameaçada de Extinção" foi incluída na categoria "Criticamente em perigo". Neste contexto, o objetivo deste estudo foi elucidar o modo de reprodução de D. ibiramensis, empregando-se experimentos de polinização manual e análise genética, bem como seu sistema de polinização e sua diversidade e estrutura genética, visando obter informações que auxiliem na elaboração de estratégias de conservação para a espécie. D. ibiramensis possui inflorescências simples e ramificadas com, em média, 58 e 137 flores, respectivamente. Suas flores apresentam formato de sino, corola amarela e sépalas variando de verdes a alaranjadas, e eixo da inflorescência variando de verde até avermelhado. Ocorre a abertura de uma a três flores por dia por indivíduo. A antese se inicia em torno de 7h00 e as flores têm duração de um dia e meio. O volume de néctar acumulado é de 27,75 L flor-1, com pico de produção no início da antese da flor, e a concentração de açúcares totais média é 22,38%. A mamangava Xylocopa (Neoxylocopa) brasilianorum juntamente com o beija-flor Thalurania glaucopis são os principais polinizadores de D. ibiramensis. Os experimentos de sistema reprodutivo indicaram que a espécie possui auto-incompatibilidade, a julgar pela inviabilidade de sementes provenientes dos tratamentos de autopolinização (manual e espontânea) e agamospermia. As estimativas de diversidade e estrutura genética, obtidas a partir de progênies e empregando-se nove locos alozímicos, mostraram que D. ibiramensis possui alta diversidade gênica, baixa endogamia e forte estruturação. A grande quantidade de alelos muito raros e a detecção de alelos fixados sugerem fortes efeitos de deriva genética. As populações que se situam a montante no Rio Itajaí do Norte são as que apresentam maiores índices de variabilidade genética e, possivelmente, constituam o centro de diversidade genética da espécie. As estimativas de taxa de cruzamento multilocos atribuem à espécie sistema misto de reprodução, com predominância de cruzamentos. Somando-se este resultado ao obtido pelos experimentos de biologia reprodutiva, sugere-se que D. ibiramensis apresenta sistema de auto-incompatibilidade parcial. Muitos cruzamentos ocorrem entre rosetas próximas, implicando em cruzamentos biparentais e coeficientes de coancestria, em geral, maiores ou próximos aos esperados para irmãos-completos. A manutenção in loco de todas as populações existentes de D. ibiramensis é extremamente necessária para sua conservação em longo prazo, enquanto a conservação ex situ da espécie deve ser encarada apenas como uma forma complementar àquela in situ
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Plano de viabilidade de abertura e operacionalização de uma empresa de consultoria empresarial em licitações
No full textTCC (graduação) - Universidade Federal de Santa Catarina, Centro Sócio Econômico, Curso de Administração.O empreendedorismo é uma área que amplia o interesse de jovens brasileiros a cada ano, e alinhada com o mercado de consultoria empresarial e às compras públicas brasileiras, criam um campo pouco ou nada explorado no cenário nacional atualmente # o de consultoria empresarial em licitações. Com expectativas no âmbito do empreendedorismo e com o intuito de explorar este novo horizonte, o seguinte estudo visa analisar a viabilidade de abertura e operacionalização da Reitz- Meintanis Consultoria, através de um plano de negócios. O mesmo auxiliará o empreendedor a entender melhor o mercado que deseja inserir o seu negócio, concorrentes, fornecedores, parceiros, estratégias, além de analisar a sua viabilidade mercadológica e financeira. Para realização do estudo, foi realizada uma pesquisa de caráter qualitativo e quantitativo e foram aplicados questionários com as empresas que farão parte do estudo mercadológico. A pesquisa realizada utilizou fontes primárias e secundárias. Como resultado, verificou-se que existe um déficit de empresas e profissionais especializados em consultoria empresarial no ramo de licitações. Além disso, concluiu-se que é viável abrir e operacionalizar a empresa de consultoria empresarial em licitações, a partir de 2010, na região da Grande Florianópolis, SC. No que tange o estudo econômico-financeiro, o negócio se mostrou economicamente viável, de baixo investimento inicial e baixo custo operacional. Ao final foram colocadas ainda sugestões de melhorias para o sistema de licitações brasileiro na modalidade pregão eletrônico, a qual representa mais de 80% das licitações realizadas pelo Governo Federal atualmente e que, talvez por ser um novo modelo de compras, careça de melhorias
