I denna uppsats har det studerats hur kyla påverkar Robot 70 skyttens prestanda. För att göra detta har en hypotesprövande metod använts. Hypotesen lyder: ”En robotskytts finmotorik påverkas av kyla så till den grad att träff inte är sannolik.” Hypotesen används till hjälp att svara på följande frågeställningar: Frågeställning 1: I vilken utsträckning påverkas robot 70-skyttens finriktningsförmåga av kyla?

The implementation of planned organizational change is ultimately a communication-related phenomenon, and as such, it is imperative that organizational communication scholars examine the interactions surrounding EHR implementation and understand how users (e.g. healthcare practitioners) utilize, evaluate, and deliberate this new technological innovation. Previous research on planned organizational change has called for researchers to adopt a more dynamic perspective that emphasizes the active agency of organizational members throughout implementation processes and focuses on informal implementers and change reinvention (work-arounds) as individuals actively reinterpret and personalize their work roles during implementation socialization. This dissertation seeks to fill this gap in research by demonstrating how communication between doctors, nurses, and other health professionals affects the adoption, maintenance, alternation, modification, or rejection of EHR systems within health care organizations. To delve into these inquiries and examine the intersecting domains of medical informatics and organizational communication research, this dissertation proceeds in the following manner: First, a literature review, capitalizing on Laurie Lewis’s work in planned organizational change and social constructionist views of technology use in organizations, outlines the assumptions that undergird this research. Next, this dissertation builds a model that predicts the communicative and structural antecedents of the study outcome variables, which include 1) organizational resistance to EHR implementation, 2) employees’ perception of EHR implementation success, 3) levels of change reinvention—or work-arounds—due to change initiatives and activities, and 4) employees’ perceptions of the quality of the organizational communication surrounding the change. Hypotheses guiding the model specification are provided and are followed by a description of the empirical methods and procedures that were utilized to explore the variable relationships. Results of the SEM model suggest that work-arounds could play a mediating role governing the relationship between informal social influence and the outcome variables in the study. In addition, one-way ANOVAs and multiple regression analyses reveal that physicians are the most resistant to EHR implementation and perceived change communication quality positively predicts perceived EHR implementation success and perceived relative advantage of EHR and negatively predicts employee resistance. A discussion of the expected and unexpected results is offered in addition to study limitation and future directions. / text

This study investigates the viability of using Human Intelligence Tasks (HIT) in password categorization. To achieve this, this study constructs and performs a HIT experiment on the online crowdsourcing platform Amazon Mechanical Turks. The study performs the experiment on the site Amazon Mechanical Turks, and gathers data in the form of answers from the workers. A a mixed quantitative and qualitative analysis of the data is performed to investigate on the workers ability to derive the categories of passwords from different categories and difficulties. The study results indicate that HIT workers seem to be unable to reliable categorize more complex passwords correctly, compared to more common and simple passwords. With this result, the study concludes that the quality and reliability of HIT password categorization is lower than would be required to make HIT a valid method for password categorization. The study ends with a discussion on how and why this may be the case and briefly discuss on how the HIT task might be changed in future development to increase its viability.

abstract: This document highlights the increased involvement of &ldquo; college boys &rdquo; or &ldquo; white college boys &rdquo; - better-educated middle-class white and light-skinned persons - in steelbands in the late 1940s and early 1950s. Following an introductory overview of the demography of Trinidad and Tobago, the history of Carnival, and the interregnum of the temporary instruments used between the ban of indigenous drums in the 1880s and the invention of the steelpan at the end of the 1930s, this document will examine the history and membership of these college boy bands, with particular emphasis on the Hit Paraders. Two factors that highlight the vital role played by these college boy steelbands are discussed: commercial sponsorship of bands, and support that bands received from the People's National Movement Party. A detailed timeline of steelpan invention and innovations is also included. / Dissertation/Thesis / D.M.A. Music 2011

Apesar de sua import?ncia econ?mica, muito pouco ? conhecido molecularmente sobre o processo de flora??o em cana-de-a??car. Este processo fisiol?gico pode promover uma perda de at? 60% na produtividade de a??car ou bioetanol. Desta forma, este trabalho teve como objetivo caracterizar um gene hom?logo ao gene que codifica a prote?na HINT1, identificado anteriormente em bibliotecas subtrativas de flora??o. An?lises gen?micas da estrutura g?nica e regi?o promotora permitiram observar que existem pelo menos dois genes distintos hom?logos ? HINT em cana-de-a??car. An?lises de bioinform?tica mostraram a conserva??o do dom?nio proteico caracter?stico da superfam?lia HIT e indicam uma rela??o filogen?tica associada ? localiza??o celular. Al?m disso, foi observada uma poss?vel rela??o com as prote?nas da fam?lia SBTILISIN-like por meio das informa??es dispon?veis em interatomas. Isto sugere que o gene HINT de cana-de-a??car pode estar relacionado ao desenvolvimento vegetal, havendo v?rias possibilidades de intera??es para a regula??o do processo de indu??o floral, pois as sequ?ncias presentes nas regi?es regulat?rias indicam que a express?o diferencial de HINT seria relacionada tanto com fatores clim?ticos presentes na regi?o Nordeste do Brasil quanto ? estresse bi?tico e fito-horm?nios. Al?m disso, os fen?tipos relacionados ao florescimento tardio indicam que a influ?ncia de HINT pode ocorrer devido ao ac?mulo de produtos na sua atua??o enzim?tica. Por estas caracter?sticas este gene pode ser utilizado como um marcador na sele??o de novos cultivares. / The sugarcane is a monocot plant grown in tropical and subtropical regions, with Brazil being the largest producer. Despite its economic importance, little is known about the molecular flowering process in sugarcane. This physiological process can promote a loss up to 60% in sugar or bioethanol. Thus, this work had as objective characterize a HINT1 homologous gene previously identified in subtractive libraries of flowering. Genomic analysis of gene and promoter region structure allowed the observation that there are at least two distinct genes homologous to HINT on sugarcane. Bioinformatics analyses showed the conservation of the characteristic protein domain of HIT superfamily and indicate a phylogenetic relationship associated to cell location. Moreover, a possible relation with the SBTILISIN-like protein family through the information available in interatomas was observed. This suggests that the HINT gene of sugarcane can be related to plant development, there are several possibilities of interactions in the regulation of floral induction process, because the sequences present in regulatory regions indicate that differential expression of HINT was related to with climatic factors in the Northeast region of Brazil as well as to biotic stress and phytohormones. Furthermore, the sugarcane phenotypes indicate that the influence of HINT may happen due to product accumulation of its enzymatic activity. For these characteristics this gene can be used as a marker in the selection of new varieties.

In present-day situation many libraries use detectors so that they can be able to prevent attempts too take out books without registering them. The university library in Jonkoping is one of the libraries that have such a detector. But unfortunately it doesn’t always work correct and can also react on other things a part from books. This is a big problem since the library staff don’t have time to check all signals that comes from detector. This paper will focus to help the university library in Jonkoping to identify the causes of the false alarms. This paper have the purpose to help library staff to decrease the false alarms so they can be able to get more time over to examine the essential signals from the detector. To be able to identify the causes of the false alarms two experiments was implemented. 180 persons participated, they were divided into three subgroups.

One factor was the books that were send from other libraries in Sweden, they hadn’t been unimagnetised and the other reason was the self-service machine. In the conclusion and discussion two simple recommendations have been given to help the personnel: • To inform all other libraries that send books about the problems that the university library in Jonkoping has with books that aren’t unimagnetised. In this way they will be more careful before they send away the books. • To write a note with information about the self-service machine so that the students learn how to use this service. These simple recommendations will help the library to decrease the false alarm.

Interaction is an important and essential aspect of the educational learning processes, since it can be used in a wide range of educational settings, in diverse ways (Anderson, 2002). Personal response system technologies (PRS), also known as Clickers, facilitates interactivity with an audience, enabling participants to instantly respond to posed questions and provides a representation of the collected data. The implementation of such systems in real pedagogical settings enables teachers to obtain interactions within big classes while preserving the lesson’s flow (Martyn, 2007).SMS-HIT is a PRS based on mobile devices enabling student interactions via SMS or web, designed and developed in order to support learning and assessment activities in real educational or training situations (Kohen-Vacs, Ronen, &amp; Bar-Ness, 2012). The users create and manage various activities in different topics and pedagogical goals. Types of interactivities offered by this system include voting by selection, free text and submission of quantitative data.A Design based research was conducted in order to evaluate different capabilities that SMS-HIT enables; this study aims to develop additional types of interactions to be added to the system, in order to promote the use of class interaction supported by PRS. During each of the three research iterations, the users’ usage, needs and suggestions have been investigated. According to the findings suitable additions were developed using .NET, combined with JQuery, HTML and CSS.The additional capabilities that have been developed, engage in a new ability of SMS-HIT - sequences activities: creating and managing sequences activities, presenting them and allowing audience to respond to them using mobile devices – one activity after the other.As a result of improving the system, users enjoy new and effective capabilities that were developed to meet these needs. In practice, the use of the SMS-HIT has become wider as more users create varied activities which contains diverse pedagogies.

In this thesis we are presenting a design-based research aimed to extend an existing mobile-based environment named “Treasure-HIT”. “Treasure-HIT” is an environment which uses the available mobile technology to enable teachers to conduct pedagogical “Treasure Hunt” games for their students. At baseline (January 2013), “Treasure-HIT” was at its early stages and has not yet been officially released; only a few teachers were granted access to it. The goal of this thesis was to test the system with teachres in order to understand the actual needs to detect difficulties and usabily limitations and to improve the system accordingy.The sudy was conducted as a design-based research that included three iterations. Within each iteration we have identified needs expressed by teachers and improved the relevant system features. The outcome of this thesis was the design, development and implementation of 7 different features that increased the usability of the “Treasure-HIT” environment and its potential to effectievy support the creation and enactment of pedagogical location based activities.
