Recent years has seen a tremendous increase in both the performance of handheld devices and the use cases they are required to fullfil. Indeed, operations previously reserved for handling on personal computers have begun being executed on smart phones and tablets instead. This revolutionary development allows one to exploit handheld device hardware in novel applications.Trondheim-based start-up “Atbrox” is engaged in an EU project where Atbrox’ focus is search on mobile devices. An important component of search is the inverted index, and within, the per term postings list – an encoded list of Unified Resource Identifiers (URI). Decoding of a postings list must be fast in order to not comprimise the user experience, but is also required to hold a small storage footprint. As the first to our knowledge, this thesis attempts to identify the properties of postings list encoding and decoding on handheld devices.Variable-byte coding, Group Varint coding, and Elias gamma coding are implemented in Objective-C. Performance is surveyed by benchmarking three devices out of Apple: A 5th generation iPod, a 4th generation iPad, and an iPad Air. Executions are run from disk to-disk, i.e. by reading a block of data, applying either encoding or decoding, and writing the result to permanent storage. Block sizes are varied. In addition, multithreading is applied during both encoding and decoding and compared to serial executions in an attempt to identify the properties under which each coding scheme performs best.This thesis provides valueable insight to the properties of coding schemes on handheld devices. Among its findings is the varying degree of performance and compression ratio between coding schemes: Group Varint proves to outperform the two others in terms of speed, however, is lacking in terms of compression. Elias gamma code provides the best compression ratio, but is the slowest in both encoding and decoding. Results also prove a strong correspondance between block size and performance, although a point of saturation is reached at 512 KiB. Additionally, block sizes below 512 KiB display an inability to take advantage of multithreading.

Applied Behavioral Analysis<br>M.S.Ed.<br>Staff members supporting individuals with intellectual and developmental disabilities often provide the primary supervision and direct instruction to those served. These services are often provided in locations with limited resources and funding, especially within adult services. Supervisors in these settings must ensure necessary documentation and job responsibilities are completed in order to meet regulatory requirements and ensure appropriate care and treatment for individuals’ served. By providing simple and cost effective feedback, supervisors can ensure the staff members are meeting job expectations while ensuring the individuals’ served are having their needs met. This study implemented a reversal design in two separate program rooms within an adult day program to examine the effects of posted group feedback, posted group feedback paired with goal setting, as well as the effect of the placement of the postings in a conspicuous versus non conspicuous location with staff completion of required daily documentation. Results in both rooms indicated that posting group feedback alone did not have as much effect on staff performance unless paired with goal setting. The posting locations in each room also did not seem to have an effect on staff performance.<br>Temple University--Theses

In this thesis I report an investigation into the psychological, emotional and social impact of British military foreign postings on accompanying spouses. I adopted an ethnographic methodology utilising a four phase mixed method approach consisting of one quantitative and three qualitative components. The thesis was based on research data collected in Phase 1 from a systematic review of British and US military research focusing on the experiences of accompanying spouses on overseas postings. Data from Phase 2 focused on the experiences from 34 British military spouses based in one location in southern Europe and were collected via individual interviews or focus groups. In Phase 3 data were collated via an online forum from 13 other British military spouses, who had experienced postings to alternative worldwide locations, rather than the single one identified in Phase 2. The final phase represented the study’s quantitative component, which further examined the findings from the previous qualitative phases through 136 responses to an online survey. The systematic review highlighted that the impact of a foreign posting could be detrimental to the military spouse’s well-being particularly if support resources were inadequate. Thematic analysis of data from Phases 2 and 3 corroborated the importance of support networks on international postings, but also identified the fundamental influence of individual differences and personal meaning-making of the military spouse. Ultimately, in Phase 4 multiple linear regression analysis determined that a person’s level of tough-mindedness, their self-efficacy and available instrumental support were all significant predictors of the perceived level of support provided by the British military. Overseas relocations are not beneficial for all military spouses. To have a greater understanding of this impact, it is necessary to examine and combine principles in the domains of sociology and psychology. The outcome of this then feeds into adjustment theories and contributes to the field of healthcare practice. Nonetheless, the military are in a constructive position to maximise the effectiveness of support resources alongside health professionals to provide the holistic support that military spouses may need. Specifically, regular informal checks from a healthcare professional or a support worker to assess the well-being of the military spouse could help early identification of any coping problems. This together with cross-cultural awareness training and a greater involvement of the military spouse throughout the relocation process could enhance their foreign posting experience.

The purpose of this experimental study was to investigate online risk-taking behaviour among adolescents. A total of 189 adolescents were given an online self-report questionnaire containing 20 examples of possible online posts. Half of the participants were presented with an application prior to the questionnaire that provided relevant, in-the-moment information about how their posts might be used and seen by others, and the other half were given an irrelevant Internet facts application. The likelihood of posting online content was assessed based on the type of post (emotionally evocative versus personal information), the nature of the post (public versus private), the gender of the participant (boy, girl), the type of app received (PostFire versus GhostFire), as well as the interaction of these variables. Results showed that while boys and girls were more likely to report that they would post or send content privately than publicly, girls were even more likely than males to report that they would send all types of information privately. Findings indicate that adolescents, particularly girls, are unlikely to discriminate between types of content online when privately messaging with others.<br>Education, Faculty of<br>Educational and Counselling Psychology, and Special Education (ECPS), Department of<br>Graduate

These platforms will not only enable information exchange from public spaces, but will also support more complex tasks like enterprise integration, informal collaboration, and public need servicing. To test the effectiveness of our system, we deployed SKINNI on four kiosks throughout MIT CSAIL. Usage statistics that we have gathered suggest that SKINNI has been well-received by both lab members and visitors. In short, SKINNI has contributed to the utility of ubiquitous computing in transitional spaces like elevator lobbies, hallways, and lounges.<br>by Tyler Bruce Horton.<br>M.Eng.

Social media has influenced the world in many different ways and the sphere of employment law is no different. We see a dramatic increase in cases regarding the dismissal of employees for posts on social media and this results in the important question: Is a negative or derogative post on social media a valid reason for a dismissal? Even though we do not have specific legislation dealing with social media in the workplace, the Labour Relations Act 66 of 1995 provides us with clarity as to the reasons why an employee may be dismissed. The Act further states the substantive and procedural aspects of each type of dismissal one must comply with before a dismissal can be deemed fair. It is important for an employer to have a code of conduct, otherwise known as a disciplinary code. That clearly stipulates the rules within the employment relationship. Such a code or policy will also provide the suggested consequences for the breach of said rules. If such a breach resulting in misconduct is classified as serious, dismissal may be an appropriate sanction. This dissertation seeks to determine whether a negative or derogative post on social media can be regarded as a form of misconduct and a valid ground for a dismissal in terms of the South African labour law sphere. Section 188 of the Labour Relations Act provides us with the three grounds for a fair dismissal, these being an employee?s conduct or capacity, or the operational requirements of the employer. To reach such a conclusion, various legislation will be examined and the South African position will be compared to the legal position in the United Kingdom.<br>Mini Dissertation (LLM)--University of Pretoria, 2017.<br>Mercantile Law<br>LLM<br>Unrestricted

This study evaluated the effects of public postings on energy conservation behavior at a public university, using a multiple baseline design across three settings; bathrooms break rooms, and conference rooms. The behavior of building occupants was recorded to assess the frequency at which those individuals would turn lights off upon exiting an unoccupied room. The independent variables implemented by experimenters (light-switch plate stickers and laminated signs) had little to no effects on cumulative instances of lights turned off however, the installation of motion sensor lights produced better results. Across all conditions, lights were turned off most frequently in conference rooms (65% of observations) followed by break rooms (9% of observations), and bathrooms (3% of observations).

The aim of this study was to explore the experiences of the spouses of South African diplomats on a posting in a foreign country. The study focused on the factors that enabled or hindered effective adjustment during posting. Research conducted showed that one of the greatest challenges facing international assignments is that organisations do not only deal with an employee but the whole family, their needs and expectations in the relocation process. The adjustment constraints in this study referred to pre-departure preparation, support provided by the Department, religion and cultural differences or similarities, foreign language, environmental factors and personal health. A qualitative research approach was applied. Data was collected through a semi-structured interview schedule. The study was conducted among nine (9) spouses who returned from posting between 2009 and 2011. Some of the spouses completed the posting whilst others returned prematurely due to adjustment problems. The findings indicated inconsistencies on how the Department prepares and supports spouses before and during posting; and that cultural and religious differences, foreign language competence and environmental factors have a considerable impact on the adjustment of spouses in a foreign country. Social support network, particularly the Embassy staff and diplomatic spouses’ associations play a crucial role in helping spouses to adjust. The study also found that spouses’ inability to adjust can result in early termination of posting. The recommendations are that the Department should review the training curriculum and provide support to spouses during the posting. The study will benefit the department, the diplomats and spouses in future postings.<br>Dissertation (MSW)--University of Pretoria, 2014.<br>tm2015<br>Social Work and Criminology<br>MSW<br>Unrestricted

The purpose with this study was to examine whether gender moderate the associationbetween body satisfaction and posting photos of exercise and training on Instagram. We usedan online survey to collect our participants that we posted in a local social network site forstudents in a swedish medium sized city (n = 239). The results of the moderated regressionanalysis showed that gender affect the association between body satisfaction and postingphotos of exercise and training on Instagram. As we hypothesized, men who rated high inbody satisfaction posted more photos of exercise and training on Instagram. Women’s postingof exercise and training on Instagram was not affected by their levels of body satisfaction.<br>Syftet med denna studie var att undersöka om kön modererar associationen mellankroppstillfredsställelse och att publicera foton av motion och träning på Instagram.

Resultatet av moderation regressionsanalysen visade attkön påverkade associationen mellan kroppstillfredsställelse och att publicera foton av motionoch träning på Instagram. Enligt vår hypotes så visade resultatet att män med hög nivå avkroppstillfredsställelse publicerade mer foton av motion och träning på Instagram. Kvinnorspublicerande av motion- och träningsfoton på Instagram påverkades inte av deras nivå avkroppstillfredsställelse.

In questo studio intendo affrontare il tema della distinzione di genere e di come venga perpetuata attraverso la rappresentazione del cibo nell’ambito dei social network. Partendo dal presupposto che il genere sia una reiterazione di norme e comportamenti interiorizzati e non un’essenza innata, il mio scopo è di dimostrare quanto il significato attribuito ad alcuni tipi di cibo rappresenti una delle barriere da abbattere per arrivare alla libertà di genere. Infatti, questa barriera può essere camuffata sotto il nome di “tradizione” o “cultura” e, di conseguenza, accettata poiché ciò che viene ritenuto “tradizione” è generalmente visto in modo positivo e non ha bisogno di essere modificato. Quello che cambia è però il modo e i mezzi attraverso i quali queste idee vengono diffuse e rafforzate. Se alcuni studi precedenti si sono concentrati sulle trasmissioni televisive come mezzo primario di diffusione, io credo che nell’ambito del territorio giapponese, oggetto della mia ricerca, i tempi siano maturi per spostare l’attenzione su nuovi mezzi di comunicazione che si sono rivelati più efficaci ed adatti a condividere questo tipo di contenuti.

The purpose of this study was to explore the alignment of soft skills sought by current business IS entry-level employers in electronic job postings, with the integration of soft skills in undergraduate business information systems (IS) syllabi of public four-year universities in Texas. One hundred fifty job postings were extracted from two major electronic career databases. Ten undergraduate AACSB-accredited programs in the field of business information systems (IS) were investigated, and syllabi for the 70 major courses of the business IS programs were obtained for review. Content analysis was applied to all job postings and syllabi, exposing all soft skills related to the 9 categories used in this study adapted from the 21st Century Framework for Learning (Partnership for 21st Century Learning, 2009). Frequencies were tabulated to determine rank of soft skills in job postings and syllabi, and Jaccard’s coefficient statistic of occurrence was used for cluster analysis. Soft skills within all 9 categories were found in job postings (n = 1554) and course syllabi (n = 774). Three soft skill categories were aligned between job postings and syllabi: (1) initiative and self-direction, (2) social and cross-cultural skills, and (3) flexibility and adaptability. However, because differences in the higher ranked frequencies of soft skills in job postings and syllabi were noted, the null hypothesis of this study was rejected.

Applied Behavioral Analysis<br>M.S.Ed.<br>Three interventions using public posting and review of client data in order to increase the effectiveness of staff implementation of functional communication training (FCT) within a school setting were compared. These interventions included: public review and posting of client data, public review and posting of client data paired with a coded shape for each staff member, and public review and posting of client data paired with a coded shape for each staff member with added reinforcement incentives. There were three student participants and three staff participants. For two student participants, FCT increased from baseline through intervention phases and staff were more likely to implement functional communication training during the final phase where reinforcement was added for the staff. Added reinforcement increased staff implementation of FCT paired with public review and posting of client data. For the third participant, results varied, but staff implemented the most during the public review and posting phases compared to baseline and reached a mean of 10 responses per session. There was also a negative correlation between functional communication responses (FCR) and challenging behaviors for two participants. This supports previous research and demonstrates the value of functional communication training as a behavior intervention tactic.<br>Temple University--Theses

Purpose &amp; Research questions: The purpose of this study is to examine how the use of social media as a marketing channel has influenced the company's way of working. With this purpose in mind, our research questions were formulated as follows: 1. Why are social media agencies a growing phenomenon, even though there are clear tendencies that social media are designed to be, as far as possible, a free method for all users? 2. Why do business companies purchase social media agencies to succeed in social media? Methodology: Qualitative method with a selection of eight semistructured interviews. Conclusion: The study's findings show that social media as a marketing channel has contributed to a change in companies way of working. The study shows that it is knowledge and time that are the mainfactors why companies choose to outsource a part of their organization. Furthermore the communication between consumers and companies has changed significantly. The social media agencies are growing in the same pace as the social media are developing.

The goal of my work was to analyze the issue of selection, posting and employees management on the projects in the European Union and proposal for optimalization of processes associated with this issue for the company Teradata.

Lo studio si caratterizza per l assunzione di una prospettiva di ricerca preordinata all'analisi dell eterogeneo sistema di fonti in base al quale viene determinata la disciplina applicabile al lavoratore distaccato nell ambito di una prestazione transnazionale di servizi. L attenzione viene concentrata, in particolare, sul micro-sistema di conflitto costituito dagli artt. 3, 8, 9 e 21 del regolamento Roma I, nonché sull interazione operativa di tali norme tra di loro e con la direttiva n. 96/71/Ce, la quale svolge, rispetto alle prime, un complesso ruolo di integrazione, fonte di rilevanti dubbi interpretativi. L analisi di tali profili internazionalprivatistici centrale nella ricerca si snoda parallelamente a quella delle più significative pronunce della Corte di giustizia sul rapporto tra i singoli strumenti mediante i quali opera il sistema di conflitto (norme imperative, norme di applicazione necessaria e ordine pubblico) e le libertà comunitarie, ciò al fine di comprendere secondo quali modalità ed entro quali limiti le differenti istanze sottese a ciascuno di questi elementi siano in grado di modellare la scelta della legge operata dalle parti. Tale opzione metodologica trova la propria giustificazione nella esigenza di dar conto delle problematiche poste dal sistema di conflitto oggetto di indagine e nel tentativo di tracciare un quadro delle risposte ad oggi fornite dalla giurisprudenza sul punto.

Sociala medier har utvecklats till den moderna tidens platsbank och har skapat en spridning av annonseringsplatser. I två studier undersöktes arbetssökandes upplevelse av denna utveckling. Studie 1 bestod av 30 kvalitativa enkäter som resulterade i följande teman: (1) relationer, (2) ovetande och (3) lättillgänglighet. Studie 2 bestod av 11 djupintervjuer som resulterade i de tre ovannämnda tema samt (4) aktivering, (5) sociala medier speglar personlighet och (6) marknadsföring. Båda studierna visade att individen upplever att denna förändring har skapat nya möjligheter och påfrestningar för den arbetssökande. Resultatet i de två studierna beskriver sociala mediers påverkan på hur och var individer söker arbeten, samt känslan av att deras privatliv och personliga egenskaper har en större inverkan på individens anställningsbarhet. Resultaten kan ligga till grund för vidare studier om arbetssökande och sociala medier.

The purpose of this study was to empirically evaluate the effects of a positive peer reporting package, namely the Duck, Duck Tootle Intervention Program on on-task behavior of target students and classwide on-task behavior. An ABAB withdrawal design was used to evaluate the effects of the tootling package on classwide and target students rates of positive peer reporting and on-task behavior. Cluster sampling was employed to select a total of 10 classes for this study. Five intact regular education elementary classrooms were chosen across grade levels to serve as the experimental group. Two target students identified by each classroom teacher as having behavior and/or academic difficulties were participants in the study. This 21-day intervention was implemented in a Chapter I elementary school, located within a low-income suburb in a large metropolitan area in the southwestern United States. The students were in kindergarten through fourth grade and ranged in age from 5 to 9.6 years. Specific target behaviors were identified for each participant (e.g. out-of-place behavior, inappropriate noise). The collected data for each of the 10 elementary school target students in this study included (a) percentage of on-task behavior, (b) percentage of target behavior, and (c) individual tootle counts. Also included in data collection were classwide tootle counts. Teacher procedural integrity data was also obtained. Results revealed that during the tootling intervention phase, in which group contingency and feedback procedures were implemented, on-task behavior increased and the mean number of individual and classwide tootles increased. Decreases in on-task behavior and mean tootles were observed during the second baseline phase. Limitations associated with the current study, implications for implementation in alternative education settings and future research are discussed.

Social networking sites are a major networking tool for consumer interactions as they provide a platform for communication, socialization, and learning activity. Subsequently, social media has become an important marketing tool for advertising companies’ messages. As a result, fashion brands such as H&M and Victoria’s Secret started to show more brand ads on Facebook. Facebook is one of the most powerful social networking sties due to its ability to reach to broad consumer groups through a brand page. However, research regarding this topic is limited as the social networking sites is relatively a new phenomenon. Therefore, the purpose of this research is to examine the effect of the brand’s comments in attenuating (enhancing) negative (positive) influence of other consumer’s postings on brand trust and purchase intention of other consumer’s postings on social media. Findings from this study revealed that there is no moderating effect of brand comments of the relationship between other consumer’s postings and brand trust, while positive other consumer’s postings has a significant effect on consumers’ brand trust. Also, there were no significant differences among other consumer’s postings, brand comments and purchase intention relationships. These findings add to the previous literature explains that brand should interact with consumers frequently in order to induce positive other consumer’s postings to develop brand trust. By using the consumer socialization theory to investigate Facebook marketing, this study provides insights and information on consumer attitudes and behaviors related to Facebook brand page.

A bank borrowing some money has to give some securities to the lender, which is called collateral. Different kinds of collateral can be posted, like cash in different currencies or a stock portfolio depending on the terms of the contract, which is called a Credit Support Annex (CSA). Those contracts specify eligible collateral, interest rate, frequency of collateral posting, minimum transfer amounts, etc. This guarantee reduces the counterparty risk associated with this type of transaction. If a CSA allows for posting cash in different currencies as collateral, then the party posting collateral can, now and at each future point in time, choose which currency to post. This choice leads to optionality that needs to be accounted for when valuing even the most basic of derivatives such as forwards or swaps. In this thesis, we deal with the valuation of embedded optionality in collateral contracts. We consider the case when collateral can be posted in two different currencies, which seems sufficient since collateral contracts are soon going to be simplified. This study is based on the conditional independence approach proposed by Piterbarg [8]. This method is compared to both Monte-Carlo simulation and finite- difference method. A practical application is finally presented with the example of a contract between Natixis and Barclays.

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico<br>O objetivo do presente trabalho à estimar o modelo de busca por emprego com heterogeneidade nas produtividades das firmas com microdados da Pesquisa Mensal de Emprego - PME do ano de 2009. Estima-se o modelo para as seis regiÃes metropolitanas abordadas pela PME. Ademais, consideram-se dois mecanismos de determinaÃÃo dos salÃrios: salÃrio postado por firmas monopsonistas e atravÃs de uma barganha bilateral de Nash. Para estimar os modelos, utiliza-se o mÃtodo nÃo-paramÃtrico desenvolvido em Bontemps, Robin e van den Berg (2000). Encontra-se uma heterogeneidade relevante entre os parÃmetros estruturais estimados para as seis regiÃes metropolitanas. AlÃm disso, o modelo com determinaÃÃo de salÃrio via barganha apresenta resultados mais plausÃveis e nÃo rejeitados pelos dados.<br>The aim of this work is to estimate an equilibrium job search model with heterogeneity in productivities of firms using microdata from the Monthly Employment Survey (PME) collected in 2009. The model is estimated for the six metropolitan regions covered by the PME. Moreover, it is considered two mechanisms of wage determination: wage posting by monopsonistic firms and as a outcome of a Nash bilateral bargaining. To estimate the model, we use the non-parametric method developed by Bontemps, Robin and van den Berg (2000). There is a significant heterogeneity among the structural parameters estimated for the six metropolitan regions. Furthemore, the model with wage determination through bargaining show plausible results and not rejected by the data.

Active research of SMAs has shown that its Seebeck coefficient is sensitive to its martensitic phase transformation and has the potential to determine the SMAs state of transformation. The combination of Shape Memory Alloys, which have a positive Seebeck coefficient, and Constantan which has a negative Seebeck coefficient (-35 mV/K) results in a thermocouple capable of measuring temperature. The work presented in this thesis is based on the development and design of this sensor. This sensor is used to study the hysteretic behaviour of SMAs. Although Shape Memory Alloys (SMAs) exhibit a myriad of nonlinearities, SMAs show two major types of nonlinear hysteresis. During cyclic loading of the SMAs, it is observed that one type of hysteretic behavior depends on the rate of heating the SMAs, whilst the variation of maximum temperature of an SMA in each cycle results in the other hysteretic behavior. This later hysteretic behavior gives rise to major and minor nonlinear loops of SMAs. The present work analyzes the nonlinearities of hysteretic envelopes which gives the different maximum temperatures reached for each hysteretic cycle with respect to stress and strain of the SMA. This work then models this behavior using Adaptive Neuro Fuzzy Inference System (ANFIS) and compares it to experimental results. The nonlinear learning and adaptation of ANFIS architecture makes it suitable to model the temperature path hysteresis of SMAs.<br>Master of Science

Business Administration/Management Information Systems<br>Ph.D.<br>In the past decade, a fundamental research topic in the information systems (IS) discipline has been to examine the value of online platforms on businesses, society, and consumers, notably in the form of improved efficiency in information sharing, consumer engagement, and increased sales. However, the risks rooted in online platforms may cannibalize the value created, which have received limited attention in the literature and practice. In my dissertation, I attempt to fill this gap in the literature by providing a comprehensive analysis of the risks of online platforms from the angle of these three main entities in the ecosystem with three separate yet related essays. The first essay focuses on the risks for businesses that leverage social media platforms, and assesses how their posting on social media fan pages affects consumers’ decision to purchase and unfollow from the firms. The second essay focuses on the risks of fake news on social media and how social media platforms may use identity verification to reduce online anonymity and combat this increasingly critical social problem. The third essay focuses on estimating the risks of using monetary incentives to motivate consumers to write online product reviews, and examines how such strategy may affect product sales. Our studies have theoretical and practical implications for designing effective online platform information systems.<br>Temple University--Theses

Adossée aux cadres théoriques d’une psychologie du développement social de l’enfant, d’une sémiologie peircienne et d’une sociologie du langage, cette thèse s’inscrit dans le champ des sciences de l’éducation et cible plus particulièrement les processus de construction des inégalités d’apprentissages qui se forment dès l’école maternelle. Elle soutient l’hypothèse d’un rapport entre le symbolique, le langagier et le cognitif qui, selon les modes socialisation, conduit à des interprétations différenciées des situations d’apprentissage, dès l’école maternelle. Pour cela, elle étudie la manière dont des élèves de grande section, issus de milieux sociaux contrastés, construisent la signification des systèmes plurisémiotisés d’un objet scolaire rarement étudié, l’affiche didactique. En appui d’une méthode inductive portant sur des entretiens d’élèves confrontés à ce type de support, l’analyse des phénomènes cognitivolangagiers et de leurs variations débouche sur des résultats montrant que les modes d’interprétation des élèves se différencient selon leur capacité à symboliser et à utiliser le langage dans sa fonction élaboratrice. L’originalité de cette thèse tient au lien qu’elle permet d’établir, à partir de configurations de sujets-sociaux-interprétants, entre les modes d’interprétation privilégiés par les élèves et les représentations qu’ils se font des objets de savoir, dans le contexte des apprentissages premiers<br>Leaned with the theoretical executives of a psychology of the social development of the child, of a semiology peircian and a sociology of the language, this thesis fits in the field of sciences of education and target more particularly the processes of construction of the inequalities of training who are formed as of the nursery school. It supports the assumption of a relationship between the symbolic system, the linguistic one and the cognitive one which, according to the socialization modes, led to the interpretations differentiated from the situations of training, as of the nursery school. For that, she studies the manner whose pupils of great section, resulting from contrasted social environments, build the significance of the plurisemiotized systems of a seldom studied school object, the didactic poster. In support of an analytical method relating to talks of pupils confronted with this kind of support, the analysis of the linguistic phenomena cognitivo and their variations leads to results showing that the modes of interpretation of the pupils are different according to their capacity to symbolize and to use the language in its elaborative function. The originality of this thesis is due to the link that it makes it possible to establish, starting from configurations of subject-social-interpreting, between the modes of interpretation privileged by the pupils and the representations which they are made of the objects of knowing, in the context of the trainings first

Mestrado em Engenharia Mecânica<br>No presente trabalho é feito uma avaliação de qual a melhor estratégia de maquinagem a 5 eixos, em função da geometria do componente pretendido (postiço). São então comparadas estratégias de maquinagem a 5 eixos contínuos e 5 eixos posicionais, tendo como parâmetros de comparação o tempo de maquinagem e a qualidade do acabamento super cial do componente. Recorrendo a casos de estudo, é então estudado a in uência das trajetórias de maquinagem nos tempos produtivos, bem como a in uência dos dispositivos de xação dos componentes. Estudou-se ainda a in uência do sistema de xação dos postiços de pequeno e médio porte, no acabamento super cial, na tolerância geométrica e dimensional, e de que forma é in uenciado o número de apertos necessários para a maquinagem total dos devidos componentes. Conclui-se que para a maquinagem de postiços de pequeno e médio porte, a maquinagem a 5 eixos posicionais é melhor que a maquinagem a 5 eixos contínuos, à exceção do acabamento em contorno utilizando a estratégia swarf, embora esta estratégia esteja muito dependente da geometria do componente.<br>Abstract In the present work a quality evaluation of a better machining strategy with 5 axes is done, depending on the geometry of the desired component. The machining strategies are then compared to 5 continuous axes and 5 positional axes, having as comparison parameters the machining time and a surface nish quality of the component. Using case studies, the in uence of the machining trajectories in the productive times is studied, as well as the in uence of the xation devices of the components. It was also studied the in uence of the xation system of the small and medium sized inserts, in the surface nish, in the geometric and dimensional tolerance, and in what way is in uenced the number of tightenings necessary for the total machining of the due components. It can be concluded that for machining small and medium size inserts, machining at 5 positional axes is better than machining at 5 continuous axes, except for contour nishing using the swarf strategy, although this strategy is dependent on the geometry of the component.

This essay describes coordination of the work environment on construction sites where many entrepreneurs share workplace. As employer, the entrepreneur has main responsibility for the workers safety on the construction site, the project supervisor is responsible for the work environment, and to coordinate the work environment a coordinator of the construction work environment is appointed. The purpose of this essay is to describe how the work environment is ensured on a shared workplace. In order to answer the essays questions I’ve used a juridical method to interpret the law. Current law and regulations has been studied, as well as the industry's rules and regulations. The juridical method is complemented by social science methodology by the use of an empirical survey consisting of interviews with a coordinator of the construction work environment, and subcontractors on a construction site. The questions of this essay concerns the project supervisor’s and the entrepreneur’s safety responsibilities of the working environment, and how they ensure their joint work environment. And also the requirements imposed on the entrepreneur’s coordination responsibilities, and if the working methods differ when the workers are posted. A construction site is a complicated workplace with many companies working side by side. Requirements for cooperation and consultation are the responsibility of all employers who have employees engaged on the same construction site. Entrepreneurs who post workers in Sweden have the same employer responsibilities as other entrepreneurs, and shall ensure the work environment of the posted worker.<br>Denna uppsats handlar om samordningen av arbetsmiljön på byggarbetsplatser där flera entreprenörer delar arbetsplats. Som arbetsgivare har en entreprenör huvudansvaret för de anställdas arbetsmiljö, på byggarbetsplatsen är det byggherren som ansvarar för arbetsmiljön, och för att samordna parternas arbetsmiljö utses en byggarbetsmiljösamordnare. Studiens syfte är att deskriptivt redogöra för hur arbetsmiljö säkerställs på en gemensam arbetsplats. För att besvara uppsatsens frågeställningar har juridisk metod använts genom att tolka gällande rätt. Förutom lag och förordningar har även böcker i ämnet använts, samt branschens regler och bestämmelser. Den juridiska metoden kompletteras med samhällsvetenskaplig metod genom att vidga studien med empiriskt material i form av intervjuer med en byggarbetsmiljösamordnare, samt ett urval underentreprenörer på en byggarbetsplats. Uppsatsens frågeställningar berör förhållandet mellan byggherrens och entreprenörers arbetsmiljöansvar och hur de arbetar för att säkerställa den gemensamma arbetsmiljön. Samt vilka krav som ställs på entreprenörers samordningsansvar och om arbetssättet skiljer sig om arbetstagarna är utstationerade. En byggarbetsplats är en komplicerad arbetsplats med många företag som arbetar sida vid sida. Krav på samarbete och samråd åligger alla de arbetsgivare som har arbetstagare sysselsatta på en byggarbetsplats. En entreprenör som utstationerar arbetstagare i Sverige har samma långtgående arbetsgivaransvar som andra entreprenörer, och ska säkerställa arbetsmiljön för den utstationerade arbetstagaren.

L’activisme en els mitjans de comunicació social (SMA) s’ha convertit en un element bàsic en gairebé tots els moviments actuals al voltant del món. L’atractiu d’aquesta eina és evident en la seva prevalença i en la diversitat d’usos. Les xarxes socials permeten que qualsevol persona de tot el món sigui escoltada en qualsevol lloc, incloses aquelles que puguin implementar els canvis necessaris a nivell mundial. Tanmateix, el món encara està per descobrir com es pot utilitzar de manera més eficaç i evitar els entrebancs de convertir-se en l’anomenat slacktivism en lloc d’activisme. Molts usuaris participen en moviments com una moda i no pels canvis que es busquen, fet que en comporta una inconsistència i una disminució de l’impacte. Altres usuaris infrautilitzen les eines o les fan servir de manera incorrecta. Hi ha diverses raons per les quals els moviments fracassen i la majoria d’aquestes es deriven de la forma en què els participants en el moviment utilitzen eines per a l’activisme. Com a resultat d’això, per tal de garantir que els moviments actuals i futurs puguin funcionar amb la màxima efectivitat, l’aspecte més important a estudiar dels moviments són els participants i la seva coherència. Aquesta tesi aportarà sobre com implicar al màxim el possible els participants analitzant l’ús de Facebook per part dels participants al moviment Black Lives Matter, així com també pel Moviment per la Independència catalana, tant si els moviments han tingut èxit fins ara mitjançant una anàlisi dels canvis legals, i també mitjançant un examen de la consistència dels moviments al llarg del temps. Aquests dos moviments semblen increïblement diferents, cosa que és bona per arribar a una conclusió imparcial, tot i que tenen moltes similituds en què tots dos han tingut diversos graus d’èxit al llarg dels anys i busquen canvis tant socials com legals que transformin molt les seves respectives societats. El moviment Black Lives Matter es va crear per combatre els assassinats il·legítims d’homes i dones negres als Estats Units, així com les lleis que permeten als assassins escapar impunes. El Moviment per la Independència de Catalunya es va crear per buscar la independència de la regió de Catalunya d’Espanya. Ambdós moviments van obtenir reconeixement internacional al llarg dels anys i compten amb membres molt apassionats de les causes, que busquen transformacions i aconseguir un futur millor. Si comparem els resultats de la investigació per a cadascun d’aquests dos moviments extremadament diferents amb participants summament diferents en termes de geografia, ètnia, edat, etc., i objectius diferents, és ben clar que els patrons identificats de coherència, les respostes dels participants i fins i tot les ramificacions legals mostren, fins a cert punt, una evident correlació entre allò que ha estat efectiu en el moviment Black Lives Matter i en el Moviment per la Independència catalana. Com a resultat d’això, aquesta tesi aporta molta llum necessària sobre com utilitzar Facebook de manera més eficaç com a eina per a l’activisme, especialment mitjançant la comunicació, l’organització i la mobilització en els moviments socials. Aquesta visió ajudarà els moviments actuals i propers a aconseguir la transformació social i política que busquen i, en definitiva, a transformar el món.<br>El activismo a través de los medios sociales se ha convertido en un elemento básico de casi todos los movimientos modernos del mundo. El atractivo de estas herramientas es obvio en su prevalencia y diversidad de usos. Las redes sociales permiten que cualquier voz, en cualquier lugar, sea escuchada por cualquier persona en todo el mundo, incluidas aquellas que tienen el poder de implementar los cambios necesarios a nivel mundial. Sin embargo, el mundo aún no ha descubierto cómo se puede usar de manera más efectiva y evitar las trampas de convertirse en el llamado slacktivismo (una virtualización que no es activa, en realidad, postureo) en lugar de activismo. Muchos usuarios participan en movimientos porque están de moda en lugar de por los cambios buscados, lo que conduce a la inconsistencia y a una disminución del impacto. Otros usuarios infrautilizan las herramientas o las usan incorrectamente. Hay varias razones por las cuales los movimientos fallan, y la mayoría de esas razones provienen de la forma en que los participantes del movimiento usan herramientas para el activismo. Como resultado de esto, para garantizar que los movimientos actuales y futuros puedan operar con la máxima efectividad, el aspecto más importante de los movimientos a estudiar son los participantes y la consistencia del uso. Esta tesis arroja luz sobre cómo involucrar a los participantes lo mejor posible al analizar el uso de Facebook por parte de los participantes en el movimiento Black Lives Matter, así como en el Movimiento de Independencia de Cataluña, si éstos han tenido éxito hasta ahora a través de un análisis de los cambios legales, y también a través de un examen de la consistencia de los movimientos a lo largo del tiempo. Estos dos movimientos parecen ser increíblemente diferentes, lo cual es bueno para llegar a una conclusión imparcial, sin embargo, tienen muchas similitudes en que ambos han tenido varios grados de éxito a lo largo de los años y buscan cambios sociales y legales que transformarán en gran medida sus sociedades respectivas. El movimiento Black Lives Matter fue creado para combatir los homicidios injustos de hombres y mujeres negros en los Estados Unidos, así como las leyes que permiten a los asesinos escapar impunes. El Movimiento de Independencia de Cataluña se creó para buscar la independencia de la región de Cataluña de España. Ambos movimientos ganaron reconocimiento internacional a lo largo de los años y están formados por miembros extremadamente apasionados por las causas, logrando las transformaciones que buscan y asegurando un futuro mejor para los afectados. Al comparar los resultados de la investigación para cada uno de estos dos movimientos extremadamente diferentes con participantes muy diferentes en términos de geografía, etnia, edad, etc., y diferentes objetivos, y luego de notar las similitudes en los resultados, es bastante claro que los patrones identificados de consistencia en las respuestas de los participantes e incluso las ramificaciones legales, en cierta medida muestran una correlación obvia entre lo que ha sido efectivo en el movimiento Black Lives Matter y en el Movimiento de Independencia de Cataluña. Como resultado de esto, esta tesis arroja luz muy necesaria sobre cómo utilizar Facebook de manera más efectiva como una herramienta para el activismo, particularmente a través de la comunicación, la organización y la movilización en los movimientos sociales. Esa idea puede ayudar a los movimientos actuales y futuros a lograr la transformación social y política que buscan y, en última instancia, ayudará a transformar el mundo.<br>Social Media Activism (SMA) has become a staple of almost every modern-day movement around the world. The appeal of this tool is obvious in its prevalence, and diversity of uses. Social media enables any voice, anywhere to be heard by anyone around the world including those that have the power to implement necessary changes globally. However, the world is still yet to discover how it can be used most effectively and avoid the pitfalls of becoming slacktivism instead of activism. Many users participate in movements because they are trendy as opposed to passion for the changes sought which leads to inconsistency and a decrease in impact. Other users underutilize the tools or incorrectly use them. There are various reasons why movements fail, and most of those reasons stem from the way movement participants use tools for activism. As a result of this, in order to ensure that current and future movements can operate at maximum effectiveness, the most important aspect of movements to be studied is the participants and consistency. This thesis sheds light on how to engage participants as best as possible by analysing the use of Facebook by participants in the Black Lives Matter movement as well as the Catalan Independence Movement, whether the movements have been successful thus far through an analysis of Legal changes, and also through an examination of the consistency of the movements over time. These two movements seem at face value to be incredibly different which is good for coming to an unbiased conclusion, however they have many similarities in that both have had various degrees of success over the years and seek both social and legal changes that will greatly transform their respective societies. The Black Lives Matter movement was created to combat the wrongful killings of Black Men and women in the United States as well as the laws that allow the killers to get away with murder and unfair treatment in general. The Catalan Independence Movement was created to seek independence of the region of Catalunya from Spain. Both movements gained international recognition over the years and consist of members who are extremely passionate about the causes, achieving the transformations they seek, and securing a better future for those affected. By comparing the results of the research for each of these two extremely different movements with extremely different participants in terms of geography, ethnicity, age, etc., and different goals, and then noting the similarities in the results, it is quite clear that the identified patterns in consistency, responses from participants and even the legal ramifications to some extent, show an obvious correlation between what has been effective in the Black Lives Matter movement and in the Catalan Independence Movement. As a result of this, this thesis sheds much needed light on how to utilize Facebook most effectively as a tool for activism particularly through communication, organization and mobilization in Social Movements. That insight will help current and upcoming movements to achieve the social and political transformation they seek and ultimately aid in transforming the world.

This master thesis is devoted to tax issues of international hiring out of labour and aims to summarize this field into a complete overview. The Institute of international hiring out of labour brings us to a three-sided relationship where the employer is leased by his legal employer to an economic employer who enjoys the fruits and benefits of his work. The work is structured into five chapters. The first two chapters outline the current situation and general concepts. The third chapter can be considered as crucial. In this part of the master thesis is described the tax impact on a leased employee and the employer's business. The tax consequences for the legal employer are mentioned only in connection with the formation of a permanent establishment. The following chapter deals with some of the problems that occur in practice, and that is the confusion of the Institute of international hiring out of labour for contract for the work. The last chapter deals with some aspects of international hiring out of labour in the German Federal Republic.

<p>Project Management is multidisciplinary in nature; it involves a number of activities and requires the project manager to possess a wide variety of competences. This thesis aims to investigate which competences organizations currently require from project managers. In particular the focus of this research is to examine and contrast the “soft” (interpersonal) and “hard” (technical) competences required by the job market and to find out if organizations recognize the importance of both of them or if they pay special attention to one of them. A total of 50 online job advertisements from different industries and countries were analyzed using content analysis in order to determine what competences are valued by employers. Furthermore, 9 semi-structured interviews were conducted with project management academics and practitioners in order to provide a more in depth study and to allow triangulation between the findings. The results indicate that some competences are more valued than others. Communication, project integration management and scope management are the top three competences required by employers. The results also suggest that employers, academics and practitioners are aware of the need to balance hard and soft competences.</p>

Adossée aux cadres théoriques d’une psychologie du développement social de l’enfant, d’une sémiologie peircienne et d’une sociologie du langage, cette thèse s’inscrit dans le champ des sciences de l’éducation et cible plus particulièrement les processus de construction des inégalités d’apprentissages qui se forment dès l’école maternelle. Elle soutient l’hypothèse d’un rapport entre le symbolique, le langagier et le cognitif qui, selon les modes socialisation, conduit à des interprétations différenciées des situations d’apprentissage, dès l’école maternelle. Pour cela, elle étudie la manière dont des élèves de grande section, issus de milieux sociaux contrastés, construisent la signification des systèmes plurisémiotisés d’un objet scolaire rarement étudié, l’affiche didactique. En appui d’une méthode inductive portant sur des entretiens d’élèves confrontés à ce type de support, l’analyse des phénomènes cognitivolangagiers et de leurs variations débouche sur des résultats montrant que les modes d’interprétation des élèves se différencient selon leur capacité à symboliser et à utiliser le langage dans sa fonction élaboratrice. L’originalité de cette thèse tient au lien qu’elle permet d’établir, à partir de configurations de sujets-sociaux-interprétants, entre les modes d’interprétation privilégiés par les élèves et les représentations qu’ils se font des objets de savoir, dans le contexte des apprentissages premiers<br>Leaned with the theoretical executives of a psychology of the social development of the child, of a semiology peircian and a sociology of the language, this thesis fits in the field of sciences of education and target more particularly the processes of construction of the inequalities of training who are formed as of the nursery school. It supports the assumption of a relationship between the symbolic system, the linguistic one and the cognitive one which, according to the socialization modes, led to the interpretations differentiated from the situations of training, as of the nursery school. For that, she studies the manner whose pupils of great section, resulting from contrasted social environments, build the significance of the plurisemiotized systems of a seldom studied school object, the didactic poster. In support of an analytical method relating to talks of pupils confronted with this kind of support, the analysis of the linguistic phenomena cognitivo and their variations leads to results showing that the modes of interpretation of the pupils are different according to their capacity to symbolize and to use the language in its elaborative function. The originality of this thesis is due to the link that it makes it possible to establish, starting from configurations of subject-social-interpreting, between the modes of interpretation privileged by the pupils and the representations which they are made of the objects of knowing, in the context of the trainings first
