Differential effects of status evaluations on employees' organizational identification (OID) and the subsequent effect of OID on organization and individuals / Exploration des Effets Différentiels des Evaluations de Statut sur l’Identification Organisationnelle (IO) & Effet de l’IO sur Organisation et Individus

Hameed, Imran 29 May 2012 (has links)
La recherche empirique examine les effets différentiels de deux évaluations de statut, c'est-à-dire le prestige externe perçu (comparaison inter-groupes) et le respect interne perçu (comparaison intra-groupes) sur l'identification organisationnelle (IO). Les différences sont expliquées par la culture sociétale et la durée de l'ancienneté des employés dans l'organisation. Notre recherche explore et teste l'importance de l'IO dans le développement des aptitudes des employés au changement étant donné que l'aptitude au changement est une attitude coopérative discrétionnaire. Ensuite, nous examinons le rôle modérateur des croyances des employés relatives au changement sur cette relation. Ainsi l'effet de l'IO sur le comportement extra-rôle des employés et le bien-être psychologique des employés est également exploré. Au total nous avons reçu 360 questionnaires remplis à partir des organisations publiques en Recherche & Développement et les organisations privées du secteur bancaire et de télécommunications. Les résultats des analyses ont confirmé toutes les relations testées à l'exception de l'effet modérateur des croyances relatives au changement sur la relation entre l'IO et l'aptitude au changement. Les résultats montrent que les individus socialisés dans le contexte collectiviste accordent plus d'importance au soi publique par rapport au soi privé. Ensuite nous avons trouvé que l'effet des évaluations de statut sur le développement de l'IO augmente pendant les dix premières années du service dans l'organisation, et cet effet positif diminue après dix ans d'ancienneté. / This empirical research investigates the differential effects of two status evaluations i.e., perceived external prestige (inter-group comparison) and perceived internal respect (intra-group comparison) on organizational identification (OID). The differences are argued on the basis of societal culture and the length of tenure of employees in the organization. The importance of OID in the development of employee's readiness for change is explored and tested considering readiness for change as a discretionary cooperative attitude. Further, the moderating role of employees' change beliefs is also explored on this relationship. Whereas effect of OID on extra-role behavior of employees and the positive effect of OID on employee's psychological well-being is also explored. A total of 360 filled questionnaires were received from public sector research & development organizations, and private sector banking & telecom organizations. The results of the analyses supported all the hypothesized relationships except the moderating effect of change beliefs on the relationship between OID and readiness for change. The results exhibited that individualized socialized in collectivist context put greater emphasis on public-self as compared to private-self. It was further uncovered that the effect of status evaluations on development of OID is increasing till first ten years of service with the organization, while this positive effect is weakened after 10 years of service. This is the first study which has tried to explore the potential effects of organizational tenure and societal culture on identification process.

Les tombes royales et les tombes de prestige en Mésopotamie et en Syrie du Nord au Bronze Ancien / Royal tombs and tombs of prestige in Mesopotamia and North Syria in the Early Bronze Age

Lazzarini, Catherine Marie 26 March 2011 (has links)
Les tombes royales et les tombes de prestige sont spécifiques d’une partie de la communauté détenant un pouvoir régional ou local. Dans le contexte du Bronze Ancien en Mésopotamie et en Syrie, l’étude archéologique a permis de distinguer les tombes de prestige des autres tombes selon trois critères principaux : l’architecture monumentale, la localisation topographique et le matériel funéraire déposés dans les tombes. Ces traits constituent un ensemble de signes complexes intégré dans un discours idéologique. L’étude a eu pour objectif de replacer les pratiques funéraires dans la société et les pratiques rituelles et sociales du pouvoir. Une perspective anthropologique apportée au sujet des tombes royales et de prestige a permis de mettre en évidence comment les pratiques funéraires sont un instrument institutionnel de manipulation idéologique, intégrées dans un discours social et politique structuré. Comme d’autres moments centraux de la société, les pratiques funéraires sont des pratiques rituelles et sociales qui jouent un rôle dans la représentation du pouvoir des élites et la structuration de la communauté. Elles permettent de reproduire et de maintenir l’équilibre social et de justifier le pouvoir des dites élites. / The royal tombs and the tombs of prestige are specific of a group detaining a regional power or local power. We have identified archaeological traits in the Syrian and Mesopotamian Early Bronze Age context which could distinguish the prestige tombs from the others. These formal features are the monumental architecture, the specific location of the prestige tombs and the group of graves associated, and the grave goods. The wealth of the deposition and the structure are characteristics of the prestige tombs and it constitutes complex signs integrated in an ideological discourse. Thus, an anthropological perspective has been essential to appreciate the social implication of the elite funerary practices. As others main events in the society, funerary practices of prestige are rituals and social practices which play a role in the representation of the elite power and in the structure of the society. The royal tombs and the tombs of prestige are social instruments of ideological manipulation; the funerary practices are integrated in social discourse through rituals in order to reproduce and maintain social structure and justify the elite power.

You Are What You Eat: Malnutrition and its Determinants in Ecuador:

Stone, Lindsay January 2017 (has links)
Thesis advisor: John Michalczyk / Why do we eat the foods that we do? This question is one that is not often considered by individuals as they go about their daily lives, but can have large implications on public health – for, there is a strong, physiological connection between food consumption and one’s health and wellbeing. Accordingly, when reflecting upon the health of a nation it is often important to consider its nutritional status. Ultimately, many determinants can contribute to how and why an individual eats certain foods, as can be seen in Ecuador. In this Latin American country, for instance, historical, socioeconomic, cultural, behavioral, socioeconomic, and environmental factors (among others) can be seen to influence the different diets – and by extension, the nutritional statuses – of different ethnic, regional, and geographic populations. Though common across Ecuador, discrepancies among these groups are particularly noticeable in the highland region, the Sierra. Overall, this paper examines the different forms of malnutrition, their implications on one’s health, and their prevalence across Ecuador. Additionally, it considers how the Ecuadorian diet was shaped, and how different subcuisines lend themselves to varying forms of malnutrition. Specifically, this paper focuses on the Sierra, given that levels of malnutrition are noticeably higher in this region, and that this highland area is home to large rural and indigenous communities who are most significantly impacted by the region’s nutritional conditions. / Thesis (BS) — Boston College, 2017. / Submitted to: Boston College.

Entwicklung von Berufspräferenzen im Schulalter

Schmude, Corinna 06 January 2011 (has links)
Ausgehend vom Rahmenmodell zur Persönlichkeitsentwicklung von Schüler/inne/n nach Pekrun/Helmke (1991), der „Eingrenzungs- und Kompromisstheorie der Berufswahl“ von Gottfredson (2005) und der Typologie des Aufbaus von Berufsidentitäten Fends (1991) wird der Berufsfindungsprozess von Schüler/inne/n der Grundschule (Kl. 5) bis in die Sekundarstufe (Kl. 9) untersucht. Analysiert werden die Berufswünsche von 600 bis 3000 Befragten und ausgewählte Variablen des längsschnittlichen Datensatzes der DFG-Projekte NOVARA, SABA und AIDA (geleitet von Prof. Dr. Renate Valtin). Es werden zwei Fragestellungen verfolgt: (1) Ist die Berufswahltheorie von Gottfredson geeignet, empirisch verifiziert die früh zu beobachtende geschlechtsspezifische Weichenstellungen in der beruflichen Orientierung fundiert zu erklären? (2) Lassen sich Zusammenhänge zwischen einer krisenhaften Bewältigung der Entwicklungsaufgabe „Berufswahl“ und der Entwicklung ausgewählter schulleistungsrelevanter Persönlichkeitsmerkmale nachweisen? Wenn ja, ab wann? Die Analysen bestätigten die Forschungsbefunde zur Geschlechtstypik der beruflichen Interessenorientierung, zum Wandel vom „Traumberuf“ zum realistischen Berufswunsch sowie zu Schwankungen der Häufigkeit geäußerter Berufswünsche in Abhängigkeit von Klassenstufe und Schulform. Des Weiteren bestätigte sich die in der Berufswahltheorie von Gottfredson beschriebene Bedeutung der Kategorie „Geschlecht“ für die Präferenz bestimmter Berufswünsche, des noch akzeptierten Prestiges der Berufswünsche und des mit der Realisierung und Ausübung des gewünschten Berufs verbundenen noch zu bewältigenden kognitiven Anspruchs. Zusammenhänge zwischen der Entwicklung schulleistungsrelevanter Persönlichkeitsmerkmale ab dem Grundschulalter und einer krisenhaften Bewältigung der Entwicklungsaufgabe „Entwicklung einer beruflichen Orientierung“ in der Sekundarstufe I konnten in Bezug auf die allgemeine Schulfreude der männlichen Befragten nachgewiesen werden. / Based on Rahmenmodell zur Persönlichkeitsentwicklung von Schüler/inne/n by Pekrun and Helmke (1991), "Eingrenzungs- und Kompromisstheorie der Berufswahl" Gottfredson (2005) and Typologie des Aufbaus von Berufsidentitäten Fends (1991), the career choice process of primary school students (Class 5) to secondary school (Class 9) is examined longitudinally. The career desires of 600 to 3000 subjects are examined longitudinally, along with selected variables of the longitudinal dataset from the DFG projects NOVARA, SABA and AIDA (led by Prof. Dr. Renate Valtin). Two questions are considered: (1) is the ''Circumscription und Compromise Theory'' according to Gottfredson suitable for explaining the empirically verified gender-specific directions in career orientation, which can be observed early, on a theoretical basis? (2) Can interconnections between a critical mastering of the development task "career selection" and the development of selected school performance-related personality attributes be demonstrated? If yes, from when? Analyses confirm the gender-specification of career orientation, about the change from "dream job" to realistic career choice and about the fluctuations in frequency of stated career desires depending on school year and type of school. Moreover, the importance of the category "gender" described in the "circumscription and compromise theory" of career choice by Gottfredson is confirmed for the preference of certain career desires, of the still accepted prestige of the career desires and of the cognitive requirement yet to be mastered in conjunction with the realisation and exercise of the desired profession. Connections between the development of school performance-relevant personality attributes from primary school age and a critical mastering of the development task "development of a career orientation" in Sekundarstufe I (equivalent to Key Stage 3) could be demonstrated with regard to general happiness at school of the male subjects.

Development and application of a proteomic approach to the assessment of pollution in the marine environment

Apraiz Larrucea, Itxaso January 2009 (has links)
Today, assessment of the health of coastal waters is recognized as being important for both the conservation of nature and well-being of humans. Anthropogenic pollution has been the focus of extensive research for some time and a variety of programs for the monitoring and assessment of environmental pollution have been developed. Determination of the levels of pollution in sensitive ‘sentinels’ such as mussels, allows monitoring of these levels in a given area over a prolonged period of time. Furthermore, the biological effects of pollution are reflected in a series of biomarkers, none of which provides a general picture of the sentinel’s state of health and all of which are individually specific for certain pollutants and influenced by both biotic and abiotic factors. In an attempt to improve biomonitoring of marine pollution, we have developed two proteomic approaches here. In the first portion of the thesis, a proteomic analysis was performed on peroxisomes isolated from mussels exposed either to one of three model anthropogenic pollutants, or two different types of crude oil, or from mussels exposed to the Prestige oil spill. Application of two-dimensional electrophoresis (2-DE) provided protein expression signatures (PES) for exposure to these different pollutants.Furthermore, several individual protein components of these PES could be putatively identified. In the second portion of this work, such analysis of subproteomes was developed further in order to improve the applicability of this approach to biomonitoring. A simple fractionation procedure in combination with liquid chromatography and 2-DE provided samples from mussels residing in different regions of a pollution gradient around the harbor of Gothenburg, as well as from mussels exposed to two types of fuel oil similar to that of the Prestige that were suitable for environmental proteomics. In addition, we constructed a model for this approach that can be cross-validated in the future and applied to assess sources of fuel oil pollution in connection with biomonitoring programs.

Recommending best answer in a collaborative question answering system

Chen, Lin January 2009 (has links)
The World Wide Web has become a medium for people to share information. People use Web-based collaborative tools such as question answering (QA) portals, blogs/forums, email and instant messaging to acquire information and to form online-based communities. In an online QA portal, a user asks a question and other users can provide answers based on their knowledge, with the question usually being answered by many users. It can become overwhelming and/or time/resource consuming for a user to read all of the answers provided for a given question. Thus, there exists a need for a mechanism to rank the provided answers so users can focus on only reading good quality answers. The majority of online QA systems use user feedback to rank users’ answers and the user who asked the question can decide on the best answer. Other users who didn’t participate in answering the question can also vote to determine the best answer. However, ranking the best answer via this collaborative method is time consuming and requires an ongoing continuous involvement of users to provide the needed feedback. The objective of this research is to discover a way to recommend the best answer as part of a ranked list of answers for a posted question automatically, without the need for user feedback. The proposed approach combines both a non-content-based reputation method and a content-based method to solve the problem of recommending the best answer to the user who posted the question. The non-content method assigns a score to each user which reflects the users’ reputation level in using the QA portal system. Each user is assigned two types of non-content-based reputations cores: a local reputation score and a global reputation score. The local reputation score plays an important role in deciding the reputation level of a user for the category in which the question is asked. The global reputation score indicates the prestige of a user across all of the categories in the QA system. Due to the possibility of user cheating, such as awarding the best answer to a friend regardless of the answer quality, a content-based method for determining the quality of a given answer is proposed, alongside the non-content-based reputation method. Answers for a question from different users are compared with an ideal (or expert) answer using traditional Information Retrieval and Natural Language Processing techniques. Each answer provided for a question is assigned a content score according to how well it matched the ideal answer. To evaluate the performance of the proposed methods, each recommended best answer is compared with the best answer determined by one of the most popular link analysis methods, Hyperlink-Induced Topic Search (HITS). The proposed methods are able to yield high accuracy, as shown by correlation scores: Kendall correlation and Spearman correlation. The reputation method outperforms the HITS method in terms of recommending the best answer. The inclusion of the reputation score with the content score improves the overall performance, which is measured through the use of Top-n match scores.

Speaking Tumblr : A Case Study of Textual Communication on Social Media

Elmgren, Tove January 2018 (has links)
This essay describes a case study of textual communication on the online social mediaplatform Tumblr. The aim of the research was to analyse the communicative functions and thestylistic, sociolinguistic, and pragmatic characteristics of textual discourse on Tumblr. Usingdata gathered on Tumblr, this essay analyses discursive aspects such as function, style, andpragmatics, relating the findings to literature on topics including relevance theory and theoriesof computer-mediated communication and cyberpragmatics. The research found thatdiscourse on Tumblr is largely phatic in nature, with an overwhelming focus on the discussionof shared interests. Such discussion on Tumblr appears to heavily depend on sharedbackground knowledge, which works as a barrier of in-group discursive solidarity andprovides and furthers feelings of connectedness. This study further found that alternative useof style and grammar on Tumblr appears to be largely uniform, suggesting that divergencesfrom standard norms are a way of displaying membership of a group and obtaining covertprestige, rather than a display of linguistic innovation.

Suburban Swedish maturing : Examining variation and perceptions among adult speakers of Swedish contemporary urban vernacular / Förortssvenskan på mognadsvägen : En undersökning av variation och perceptioner bland vuxna talare av svensk ‘contemporary urban vernacular’

Young, Nathan January 2014 (has links)
Up to now, adolescent speakers have been the primary focus when researching contemporary variation in the language of Sweden’s urban areas. This study contributes to the growing body of research on the topic by examining and reporting on adult speakers of what is here referred to as förortssvenska (English: Suburban Swedish). This study focuses specifically on formal speech registers of eight young working-class men from Stockholm along with the perception and reception of their speech by two independent native-listener groups. The paper is the first to present quantifiable data on what has been previously referred to as a “staccato” rhythm in Suburban Swedish. Strong correlations are shown between prosodic rhythm as measured by the normalized pairwise variability index (nPVI) and speech speed to mean listener attitudes (R2=0.9). A strong correlation is also shown for nPVI’s influence on mean listener-projected ethnicity (R2=0.8). Alongside variation in rhythm, we also see phonemic variation that trends toward specific indexes of social identity as revealed by speaker interviews and native-listener assessments. Alongside linguistic variation among speakers, there is also significant variation within speaker peer groups. In addition to identifying specific linguistic features, the study examines social mechanisms revealed in interviews with and qualitative observations of speaker and listener participants. In exploratory fashion, ideas on variation, register ranges, meta-pragmatic stereotyping, and ethnic boundary-making are presented to make a case for treating contemporary urban variation in Swedish as a habitual semiotic extension of speaker identity. Indicators that contemporary urban variation in Swedish may be heading in the direction of sociolectal entrenchment are also discussed. / Hittills har unga talare varit det primära fokus för forskning av aktuell språklig variation i urbana Sverige. Denna studie bidrar till den växande mängden forskning i detta ämne genom att undersöka och rapportera om vuxna talare av det som här kallas för förortssvenska. Studien fokuserar specifikt på formella talregister bland åtta unga män från Stockholms arbetarklass, samt perception och mottagande av deras tal av två oberoende grupper av infödda lyssnare. Denna studie är den första som presenterar kvantifierbar data rörande den i tidigare forskning så kallade stackato-rytmen i förortssvenska. Starka korrelationer finns mellan, å ena sidan, prosodisk rytm mätt med the normalized pairwise variability index (nPVI) och talhastighet och, å den andra, de genomsnittliga lyssnarattityderna (R2=0,9). Det finns också en stark korrelation för nPVIs påverkan på genomsnittlig lyssnarprojicerad etnicitet (R2=0,8). Vid sidan av variation i rytm ser vi också fonemisk variation som trender mot specifika index för social identitet. Och vid sidan av variation i rytm bland talarna, finns också en stor variation inom kamratgrupperna. Förutom att den identifierar specifika lingvistiska drag, undersöker studien sociala mekanismer som framkommer i intervjuer med och kvalitativa observationer av talardeltagarna och lyssnardeltagarna. På ett explorativt sätt, lägger studien fram idéer om variation, registeromfång, meta-pragmatiska stereotyper och etniska gränsskapande för att framhäva argumentet för att behandla den aktuella förortsvariationen i svenska som en habituell avsiktlig utbyggnad av talarens identitet. Det diskuteras också indikatorer till att den aktuella urbana variationen i svenska kan vara på väg mot sociolektal stabilisering.
