Hinders for Eco-friendly Media Selection
This study shows that, despite organizations claiming to care for the green environment through documented environmental policies, marketing communication such as advertising media selection does not seem to be much guided by green environmental concerns. Problems with consistency and control thus seem to exist between companies’ ideas/decisions (documented environmental policies) and their actions (advertising media selection), causing the need for justification and/or hypocrisy. This study adds to prior research on the non-use of models in practice by showing that the non-use of models also exists among marketing managers when selecting advertising media for marketing communication purposes. It was found that 64 percent of the marketing managers do not make use of media selection models. In the attempt to investigate differences in the factors guiding media selection between marketing managers who use media selection models (users) and those who do not use any model (non-users), it was found that the users take a medium’s eco-friendly characteristics less into consideration than the non-users. The paper discusses that the use of models can be viewed as attempts for making more rational decisions. The findings thus suggest that rational decision-making (users) may hinder eco-friendly media selection while non-rationality (non-users) may develop more powerful organizational ideologies such as acting responsibly towards the green environment. However, this study points out a link between the use of media selection models, previous experience and rules of thumb, i.e. the users tend to make more use of previous experience and rules of thumb than the non-users. Thus, the author argues that a new approach to model use may be needed and that the media selection should not be too much influenced by the marketing managers’ previous experience and rules of thumb. Otherwise, new factors may be overlooked such as consumers’ increasing concern for the green environment in relation to consumer advertising media attitudes. Previous studies have found that current approaches to marketing planning pay too little attention to the impact of technological advances on changes in consumer media habits. Thereby the risk may exist for focusing on mainly conventional media and not selecting “new media”. The present study seems to contradict these previous findings by showing that the selection of “new media” such as media using the Internet was found among the most selected advertising media by both the users and non-users for the two communication objectives studied, i.e. brand-building and to increase sales. Thus, the results indicate that while the marketing managers adapt their media selection to changes in technological media advances they tend to overlook consumers’ increasing concern for the green environment and the environmental aspect of advertising media. The results also show differences among the marketing managers in their selection of advertising media. At the same time as the non-users tend to be more precise with the recycling of paper, they are more inclined to select paper-based media such as catalogues and brochures than the users. The users on the other hand, tend to select more electronic media such as TV, radio and cinema than the non-users. In the attempt to explain the factors guiding media selection and in particular to what extent the environmental aspect of advertising media is considered, green environmental responsibility attitudes (GERA) of the users and non-users are assessed.Media Selection; Advertising; Green Environment; Marketing Managers; Models; Green Environmental Responsibility Attitude (GERA); Rationality; Non-rationality

O papel dos pequenos roedores e marsupiais no ciclo de transmissão de Trypanosoma cruzi e T. evansi em áreas com diferentes características ambientais no Pantanal Sul- Matogrossense
A expansão das fronteiras agrícolas exigida pelo crescimento populacional humano
tem causado impactos ambientais com consequências que se estendem da escala
local à global. O Pantanal brasileiro é uma região de grande diversidade biológica e
que sofre alterações ambientais, induzidas por humanos através da pecuária
extensiva, e alterações ambientais sazonais, causadas pelo regime de inundação.
Nesta região, o Mal das Cadeiras em cavalos, causado por Trypanosoma evansi,
representa um fator de impacto à pecuária extensiva no Pantanal, onde cavalos são
utilizados no manejo do gado e como principal meio de transporte. Embora não haja
relatos da Doença de Chagas no Pantanal, Trypanosoma cruzi é encontrado
circulando em alta prevalência em animais silvestres em vários biomas. Neste
contexto, o objetivo desta tese foi avaliar o papel dos pequenos roedores e
marsupiais no ciclo de transmissão de T. cruzi e T. evansi e como alterações
ambientais causadas por humanos podem influenciar na micro e macrofauna do
Pantanal e na interação entre as mesmas. Para isso comparamos a diversidade de
roedores e marsupiais e de helmintos de Thrichomys pachyurus entre uma área de
reserva e uma área de pecuária extensiva no Pantanal, o perfil de infecção por T.
cruzi e T. evansi e analisamos ainda o impacto da infecção natural por dois
tripanosomatídeos em três espécies de roedores silvestres. A criação de gado na
área estudada não estava associada à perda de riqueza de espécies nem mudança
na composição de espécies, mas influenciou na abundância relativa das espécies e
padrão de ocupação dos habitats. O roedor O. mamorae foi a espécie que
apresentou prevalência mais alta de ambos tripanosomas, provavelmente por ser
encontrado nos mesmos ambientes utilizados tanto por Tabanídeos como por
Triatomíneos, vetores de T. evansi e T. cruzi, respectivamente. Apesar da baixa
prevalência de animais com parasitemias expressivas, os marsupiais apresentaram
maior potencial de amplificação de T. cruzi. Os roedores examinados apresentaram
baixo impacto das infecções por T. evansi e T. cruzi nos parâmetros hematológicos
estudados. No roedor T. pachyurus as infecções por T. evansi e/ou helmintos, não
apresentaram impacto relevante à saúde do animal, a julgar pelos parâmetros
hematológicos dentro dos limites normais. Este roedor apresentou alta diversidade
de helmintos, provavelmente por ocupar diversos tipos de habitat, sendo
considerado habitat-generalista nas áreas estudadas. A presença de um nematódeo
de cervídeos e porcos em T. pachyurus, apenas na área de gado, sugere que a
criação de gado concentra diferentes espécies em uma mesma mancha e/ou mesmo
tipo de habitat, ocasionando o compartilhamento de ambiente e a
transmissão/aquisição de parasitos entre espécies distintas. Concluímos que nas
áreas estudadas os pequenos roedores e marsupiais apresentam papel secundário
na manutenção do ciclo de transmissão de T. cruzi e T. evansi em comparação com
outras espécies de mamíferos no Pantanal.Earthwatch

Penn State University, CNPq/Fullbright.The demand for agriculture expansion required for the growing human population
has caused from local to global scale environmental impacts. The Brazilian Pantanal
is a region of great biological diversity, which suffers anthropogenic environmental
alterations, caused by cattle ranching, and natural environmental alterations, caused
by seasonal flooding. In this region, the horse illness called “Mal das Cadeiras”,
caused by Trypanosoma evansi, can cause major impacts to the cattle ranching
activities, where horses are frequently used for cattle management activities and
transportation. Although in the Pantanal, human Chagas Disease has not been
reported, Trypanosoma cruzi has been found in circulating in high prevalence in wild
animals in a variety of Biomes. In this context, the objective of this thesis was to
evaluate the role of small rodents and marsupials in the transmission cycle of T. cruzi
and T. evansi, and how anthropogenic environmental alterations may influence the
micro and macro fauna in the Pantanal, and also how they interact with each other.
For that the diversity of small rodents and marsupials and the helminthes of
Thrichomys pachyurus were compared between a preserved area and a cattle
ranching area, as well as the infection profile of T. cruzi and T. evansi and analyzed
the impact of the natural infection by T. cruzi and T. evansi in three species of wild
rodents. Cattle ranching was not associated to species richness loss nor to a change
in species composition, but has influenced on the relative abundance of the small
rodent and marsupial species and their habitat occupation pattern. The rodent O.
mamorae was the species with the highest prevalence of both trypanosomes,
probably for being present in the same habitats as Tabanid flies and Triatomine bugs,
vectors of T. evansi and T. cruzi, respectively. Despite of the low prevalence of
animals with expressive parasitemias, marsupials presented a higher potential for
amplifying T. cruzi. The examined rodents presented low impact to the infections by
T. cruzi and T. evansi in the studied blood parameters. In the rodent, T. pachyurus
the infections by T. evansi and/or helminthes did not present a relevant impact to the
animal‟s health, as their hematological parameters were within the normal limits. This
rodent presented high diversity of helminths, probably for occupying several habitat
types, being considered a habitat-generalist in the studied areas. The presence of a
nematode from cervids and pigs in T. pachyurus only in the cattle area, suggests that
cattle ranching forces different species to share a same habitat type and/or patch,
facilitating the transmission/acquisition of parasites between distinct species. We
concluded that in the studied áreas the small rodents and marsupials presented a
secondary role in the maintenance of the transmission cycle of T. cruzi and T. evansi
in comparison to other mammal species in the Pantanal

Differences in the mediolateral control of balance during gait between 2D and 3D bodyweight support systems
Training with bodyweight support (BWS) systems can improve the likelihood of regaining normal locomotor abilities for neurologically impaired patients. It is known that people alter their gait parameters when walking with BWS. However, it is unclear whether 2D (vertical and lateral support) and 3D (only vertical support) BWS systems affect these gait parameters differently. In this study, participants walked overground in both a 2D and a 3D BWS system to investigate the effects of this lateral support. To compare the contribution of the vestibular system between the different BWS systems, participants received galvanic vestibular stimulation (GVS). Motion capture and force plates were used to find the coupling between the GVS stimulus and the mediolateral ground reaction forces and to calculate the gait parameters. Differences in gait parameters were observed between the 2D and the 3D system. Compared to unsupported gait, participants increased their step width variability by ~10% in the 3D system. Contrarily, participants decreased step width variability by more than 15% in the 2D system. Mean step width decreased slightly in only the 3D system. The margin of stability did not change significantly in any condition. The coupling between the GVS signal and mediolateral ground reaction forces decreased in the 2D and 3D systems compared to unsupported gait, but no significant differences were observed between different BWS conditions. These results suggest that 2D and 3D BWS systems influence gait parameters differently and that they influence the contribution of the vestibular system to balance, but no significant differences between the systems can be observed in this aspect.Mechanical Engineering | BioMechanical Desig
Development of an Energy Management PFD using Total Energy Control Principles
Navigation accidents can be classified into a number of root causes. Lack of energy awareness is identified as a systematic cause of aviation incidents and accidents. A new format of the Primary Flight Display has been developed to increase the pilots awareness of the aircraft's energy state. In this display format, energy relations between speed and altitude are directly visualized, together with the relations between their derivatives: acceleration and vertical speed. It is hypothesized that the method of visualization described in this paper also allows decoupling of the control actions for a simultaneous tracking of flight path and speed targets. To provide the possibility for accurate anticipatory control, quickened symbology is added to the display format. The level of detail of the conceptual design was increased by means of a participative design approach. This paper describes the design iterations that resulted in the current format.Applied SciencesInformation Technology and SystemsTelecommunications and Traffic Control Systems Grou
