Attract and retain Generation Z in the white-collar business sector. : How to attract and retain Generation Z in the white-collar business sector?

Descos, Lucie, Gospic, Anna-Maria January 2019 (has links)
Problem  Following the expanded competition when it comes to attraction and retention of skilled workers, hence white-collar workers, organizations need to better adapt to the rapid changes in the labor market. Due to the lack of knowledge about the recent Generation Z and their perceptions and values regarding work, the Person-Organization (P-O) fit has been applied in order to gain a deeper knowledge of what attracts and retains individuals of Generation Z, in order for companies to better meet their needs.   Purpose Due to the lack of research done on Generation Z, the purpose of this study is to gain a greater understanding of the values and perceptions of Generation Z and how they operate in the white-collar business sector. Moreover, this creates a greater insight for organizations in order to help them better target the right talent pool and gain a greater understanding of Generation Z that has come to change the labor market.   Method In order to gain a greater knowledge and insight about Generation Z, a qualitative study has been performed to better understand the perception of this Generation. In-depth interviews have been conducted with Generation Z that have or are currently operating in the white-collar business sector in order to meet the purpose of this study. Semi-structured interviews were conducted in order to allow for a fruitful discussion of their values and perceptions and the likely impacts they consider when joining an organization.   Conclusion Generation Z indicated that certain aspects are to consider in the decision-making process of applying or taking a job. Indeed, their own values, beliefs and work-personal life matter to a great extent and is to be matched with the company. This study comes to the result of six determined factors influencing this decision-making process: small enterprises, flexibility trust and freedom, work/private life environmental factors, organizations values/ethics, do what they love, digital natives.

"Ingen orkar ju leta igenom 10 000 butiker" : En kvalitativ studie om Generation Zs köpbeslutsprocess och vad som påverkar dem vid köp av kläder online

Carlsson, Johanna, Ragnarsson, Linnéa January 2019 (has links)
Syfte: Syftet med denna studie är att kartlägga och tolka hur Generation Z anser sig agera och bete sig i köpbeslutsprocessen vid inköp av kläder online. Forskningsfrågor: - Hur ser Generation Zs köpbeslutsprocess ut vid köp av kläder online? - Vilka faktorer påverkar Generation Z vid köp av kläder online? Metod: Studien baseras på en kvalitativ metod och den empiriska datan har som utgångspunkt i tre fokusgruppsdiskussioner och två semistrukturerade intervjuer. Studien har en deduktiv ansats. Teoretisk referensram: Studien baseras utifrån den klassiska modellen av köpbeslutsprocessen, samt kompletteras med faktorer som påverkar vid köp online – inflytande och sociala medier, hemsidans atmosfär, tillit, pris och risk. Slutsatser: Köpbeslutsprocessen för Generation Z liknar den klassiska processen till viss del, även om flertalet nya beteendemönster kan utläsas. Olika vägar kan tas i köpprocessen och beteendet i de olika stegen ser annorlunda ut jämfört med tidigare generationer – alla stegen sker mer eller mindre online.

Personalized Advertising: Examining the Consumer Attitudes of Generation Z Towards Data Privacy and Personalization : A study of consumer attitudes towards the commercial usage of personal data

Taneo Zander, Jennifer Taneo Zander, Mirkovic, Anna-Maria January 2019 (has links)
Abstract Background The advancement of Internet technology and the ability of companies to process large amounts of information has made it possible for marketers to communicate with their customers through customized measures, namely personalized advertising. One of the primary aspects that differentiates personalized advertising from traditional advertising is the collection and use of consumers’ personal information, which have presented marketers with numerous benefits and opportunities. However, this has also raised concerns among consumers regarding their privacy and the handling of their personal information. In this study, the attitudes of Generation Z will be examined regarding data privacy, personalization, and the commercial usage of their personal information, as well as how these attitudes may impact consumer behavior. Purpose                   The purpose of this study is to examine the attitudes of consumers towards personalized advertising and the commercial usage of personal consumer data, with the focus on consumers belonging to Generation Z. Issues regarding data privacy and personalization is explored, as well as how consumer attitudes towards the personalization of advertisements may impact consumer behavior in the digital environment. Method The positivistic approach was applied with the intention to draw conclusions about a population of people, namely Generation Z. A deductive approach was implemented to test an existing theory, the Theory of Planned Behavior (TPB) with the intention to examine whether Generation Z follows the trend found in the literature; namely that younger consumers (Millennials) are more positive towards personalized advertising and the sharing of personal data for commercial purposes than older generations. The empirical data was collected through a survey, which was later analyzed through statistical measures.           Conclusion              The results suggested a predominantly neutral attitude among the survey participants regarding personalized advertising and the sharing of personal data for commercial purposes. Moreover, a positive correlation between consumer attitudes and behavioral intention to interact with personalized advertisements was detected. However, the correlation was found to be rather weak, indicating that consumer attitudes are not necessarily the strongest predictor of behavioral intention among Generation Z consumers in regards to personalized advertising.

Stereoselective Olefin Metathesis Reactions for Natural Product Synthesis

Yu, Miao January 2014 (has links)
Thesis advisor: Amir H. Hoveyda / Chapter 1. The first examples of highly Z- and enantioselective ring-opening/cross-metathesis reactions are disclosed. Transformations involve meso cyclic olefin substrate and styrenes or enol ethers as olefin cross partners. A stereogenic-at-Mo monoaryloxide monopyrrolide (MAP) complex, prepared and used in situ, is discovered for the efficient formation of Z olefins. Such complex, bearing a relatively smaller adamantylimido and a larger chiral aryloxide ligand, leads to kinetic Z-selectivity due to the size differential. In most cases, the resulting disubstituted Z olefins are formed with excellent stereoselectivity (>95% Z). Chapter 2. The protocols for efficient Z-selective formation of macrocyclic disubstituted alkenes through catalytic ring-closing metathesis (RCM) is described. Stereoselective cyclizations are performed with either Mo- or W-based monoaryloxide monopyrrolide (MAP) complex at 22 oC. Synthetic utility of such broadly applicable transformation is demonstrated by synthesis of several macrocyclic natural products: relatively simpler molecules such as epilachnene (91% Z) and ambrettolide (91% Z), as well as advanced precursors to epothilones C and A (97% Z) and nakadomarin A (94% Z). Several principles of catalytic stereoselective olefin metathesis reactions are summarized based on the studies: 1) Mo-based catalysts are capable of delivering high activity but can be more prone to post-RCM isomerization. 2) W-based catalysts, though furnish lower activity, are less likely to cause the loss of kinetic Z selectivity by isomerization. 3) Reaction time is critical for retaining the stereoselectivity gained from kinetic, which not only applicable with MAP complexes but potentially with other complexes as well. 4) By using W-based catalyst, polycyclic alkenes can be accessed with sequential RCM reactions, without significant erosion of the existing Z olefins in the molecule. Chapter 3. An enantioselective total synthesis of anti-proliferative agent (+)-neopeltolide is presented. The total synthesis is accomplished in 11 steps for the longest linear sequence and 28 steps in total, including 8 catalytic reactions. Particularly, several Mo- or Ru-catalyzed stereoselective olefin metathesis reactions as well as N-hetereocyclic carbene (NHC)-catalyzed enantioselective boron conjugate addition to an acyclic enoate have proven to be effective for convergent construction of the molecule. The most important novelty of the study incorporates the explorations of feasibility of Z-selective cross-metathesis reactions to solve the challenge of installing two Z olefins with excellent selectivity. / Thesis (PhD) — Boston College, 2014. / Submitted to: Boston College.

Effectiveness of the Altman Z-Score model : Does the Altman Z-Score model accurately capture the effects of Non-Performing Assets (NPA) in the Indian banking sector?

KITTUR, ASHA HARSHAVARDHAN January 2019 (has links)
The aim of this study is to measure the effectiveness of Altman’s Z-Score model using Non-performing assets (NPA) as a benchmark stability indicator. To do that, this paper examines if Altman’s Z Score Models capture the decline in financial health of the banks caused by the NPAs, using a two-fold analysis i.e., in advance through prediction and when the distress period is ongoing. The findings of this paper would suggest that: 1. During the distress period: The Z-Scores only marginally capture the distress caused by the NPAs, which is in line the findings of Almamy et al that the predictive ability of the model goes down during the crisis period. 2. For the future: The results of the statistical t-tests indicate that, the Z-Scores do not have the predictive ability to capture the future NPAs. Two different models that are developed by Altman - one for non-manufacturing firms and the other for the emerging markets, are used to test, if one model is more suitable than the other to the Indian banking sector. The findings of this paper suggest that, due to the uniqueness of the Indian banking sector during the NPA crisis, the ‘Emerging market model’, does not produce any significantly better results. Therefore, there is further scope to develop a tailor-made model suitable to the Indian banking sector.

Marketing viral: alternativa para atrair estudantes?: um estudo em instituição de ensino superior no Noroeste do Rio Grande do Sul

Reinhold, Fabiane Weydmann 13 December 2013 (has links)
Nos últimos anos o mercado para Instituições de Ensino Superior (IES) vivenciou importantes transformações. Além do crescente ambiente competitivo, houve mudanças no comportamento do público alvo, em virtude de avanços tecnológicos. O panorama tornou necessário investimento em novas e criativas ações para atração de estudantes. Desta forma, este estudo traz o Marketing Viral como alternativa de comunicação entre IES e público alvo. A organização estudada foi a Faculdade Três de Maio – SETREM, situada na cidade de Três de Maio, região Noroeste do Estado do Rio Grande do Sul. Este trabalho analisa a ação de Marketing Viral realizada durante a Campanha de Vestibular da Faculdade Três de Maio - SETREM em 2010, assim como desenvolve pesquisa de campo com 202 vestibulandos daquele processo seletivo, visando identificar o perfil do público alvo e percepção destes com relação à campanha publicitária. Trata-se de uma pesquisa qualitativa e quantitativa, cujos os resultados foram apurados através de dados bibliográficos, estatísticos e interpretativos. Do ponto de vista dos objetivos, este trabalho se classifica como pesquisa exploratória e descritiva. A técnica utilizada para desenvolvimento da pesquisa foi de entrevista, por meio do método Survey. Ainda, como forma de complementar o trabalho, apurou-se a percepção dos docentes da Instituição sobre a questão, tendo participação de 60 professores. A amostragem desta foi oriunda de cálculo para População Finita. Os resultados foram apresentados sob forma de tabelas, utilizando instrumento estatístico, o programa Excel. As descobertas desta pesquisa apresentam subsídios para inovação no desenvolvimento da comunicação entre IES e público alvo, além de contribuir para geração de conhecimento da temática em si. Os resultados indicam que ações estratégicas na Internet, como Marketing Viral, podem ser eficazes para IES, quando estas se voltam a comunicação com a Geração Z. Ao identificar o perfil dos estudantes, estes se mostraram completamente condicionados às tecnologias. Os discentes mostram-se dispostos a compartilhar vídeos e interagir na web, diferentemente dos docentes, com faixa etária maior. A utilização de um personagem representativo (um extraterrestre) ao conceito da campanha publicitária para ação de Marketing Viral, também se revelou eficiente para com este público. Conquistou simpatia da maioria dos entrevistados, associando-o à marca da instituição. As informações oriundas deste estudo oportunizam compreensão do fenômeno e favorecem a elaboração de novas ações de Marketing Viral. / 135 f.

Efeito do uso de primers bioativos na interface dentina-adesivo / Effect of bioactive primers on dentin--adhesive interface

Sousa, Ana Beatriz Silva 29 July 2015 (has links)
A longevidade das restaurações com compósitos está diretamente relacionada ao sucesso do tratamento estético. A vida útil das restaurações pode ser influenciada por vários fatores como o material empregado, tempo de uso clínico e a degradação da matriz dentinária por metaloproteinases da matriz (MMPs), que podem afetar a integridade da interface adesiva, fazendo com que a união dentina-­adesivo seja comprometida. Assim, buscando melhores resultados na durabilidade das restaurações adesivas, o objetivo deste estudo foi avaliar o efeito de substâncias inibidoras de MMPs (soluções de clorexidina -­ CHX a 0,2% e doxiciclina a 3%) e agente de ligação cruzada (extrato de semente de uva -­ grape seed extract - GSE a 15%) na Resistência de União (RU) de restaurações de resina composta submetidas à ciclagem mecânica. Cavidades de Classe I foram preparadas na área central da superfície exposta de 48 molares humanos hígidos, posteriormente separados em 4 grupos (n=12) de acordo com o tratamento de superfície recebido após o condicionamento de ácido: Grupo I -­ Controle (Sistema Adesivo -­ Adper Single Bond Plus -­ 3M ESPE); Grupo II -­ CHX 0,2% + Sistema Adesivo; Grupo III -­ GSE 15% + Sistema Adesivo e Grupo IV -­ Doxiciclina 3% + Sistema Adesivo. Após os procedimentos restauradores (Filtek Supreme Ultra -­ 3M ESPE), as amostras foram armazenadas em água destilada durante 24 horas a 37°C e subdividas em dois subgrupos: A -­ Controle (armazenado em saliva artificial) e B -­ Submetido à ciclagem mecânica (Coil Cycler, Proto-­tech, forca de 50 N, frequência de 1,5 Hz em 1 x 106 ciclos de aplicação). Após ciclagem mecânica, os corpos de prova foram cortados em palitos (0,8 x 0,8 mm; n = 5 por dente) e submetidos ao teste de microtração (Bisco) a velocidade de 1 mm/min. A atividade colagenolítica da MMP-­2 sob a ação dos primers bioativos foi analisada utilizando o kit EnzChek Gelatinase/Colagenase Assay (D-­12054, Molecular Probes, Eugene, OR, EUA). A atividade gelatinolítica das MMPs-­2 e -­9 após incubação com os primers bioativos foi avaliada através de zimografia convencional. Os resultados obtidos das duas análises foram apresentados na forma de porcentagem de inibição. Zimografia in situ foi realizada utilizando gelatina de fluorescência conjugada (Kit EnzChek Gelatinase/Collagenase Assay) como substrato de MMPs e avaliada com aumento de 40x através de microscopia de fluorescência. Posteriormente, os fótons fluorescentes foram analisados em software (ImageJ). Obtidos os resultados, os dados foram submetidos à análise estatística (2way ANOVA, Tukey, p>0,05) e demonstraram que os primers bioativos não exerceram influência significante sobre a RU dentina-­adesivo, independente da ação da ciclagem mecânica. A atividade colagenolítica, segundo zimografia convencional, demonstrou que os primers bioativos foram capazes de inibir as MMPs, sendo a CHX menos eficiente. Na análise de zimografia in situ, os primers bioativos diminuíram a atividade das MMPs localizadas na interface adesiva, com aumento da atividade gelatinolítica do grupo Controle sendo maior quando submetidos à ciclagem mecânica, efeito não encontrados no grupos tratados com primers bioativos. Concluiu-­se que, apesar de não apresentarem efeitos sobre a RU da interface adesiva, os primers bioativos apresentam ação sobre a degradação da camada híbrida. / The durability of composite resin restorations is one of the main points related to the success in aesthetic treatments. The longevity of adhesive restorations can be affected by various factors such as the materials, the clinical time of use and the dentin matrix degradation mediated by matrix metalloproteinases (MMPs). MMPs can affect the adhesive interface, compromising the bonding between dentin and adhesive. Thus, searching for better results on longevity of adhesive restorations, the aim of this study was to evaluate the effect of MMPs inhibitors (chlorhexidine -­ CHX 0.2% and doxycycline 3% ) and crosslinking agent (grape seed extract -­ GSE 15%) on resin composite bond strength (BS) of restorations submitted to load cycling. Class I cavities were performed in the central area of the exposed surface of 48 sound human molars. Then, it was divided into 4 groups (n=12) according to the surface treatment received after the acid etching: Group I -­ Control (Adhesive System -­ Adper Single Bond Plus -­ 3M ESPE); Group II -­ CHX 0.2% + Adhesive System; Group III -­ Doxycycline 3% + Adhesive System e Group IV -­ GSE 15% + Adhesive System. After restorative procedures (Filtek Supreme Ultra -­ 3M ESPE), the samples were stored in distilled water for 24 hours at 37°C and then subdivided into two subgroups (n=6): A -­ Control (stored in artificial saliva) and B -­ Submitted to load cycling (Coil Cycler, Proto-­tech, 50 N, 1.5 Hz, 1 x 106 cycles). After load cycling, the specimens were cut into sticks (0.8 x 0.8 mm; n = 5 per teeth) and submitted to the microtensile test (Bisco) at 1 mm/min. The collagenolytic activity of MMP-­2 under action of bioactive primers was analyzed using EnzChek Gelatinase/Colagenase Assay Kit (D-­12054, Molecular Probes, Eugene, OR, EUA). The gelatinolytic activity of MMPs-­2 and -­9 after incubation with the bioactive primers was evaluated by gelatin zymography. The results of these two analyzes were presented by percentage of inhibition. In situ zymography was performed using fluorescence conjugated gelatin (EnzChek Gelatinase/Collagenase Assay Kit) as MMP substrate and evaluated using 40x magnification under fluorescence microscopy. Then the fluorescent photons were analyzed with an appropriate software (ImageJ). The results were subjected to statistical analysis (2-­way ANOVA, Tukey, p<0.05) and the bioactive primers showed no significant influence on the dentin-­adhesive BS, regardless the load cycling action. According to gelatin zymography, the collagenolytic activity demonstrated that the bioactive primers were able to inhibit MMPs activity and CHX was less efficient. In situ zymography analysis, showed that the bioactive primers decreased the activity of MMPs located in adhesive interface. The data also demonstrated increased gelatinolytic activity on Control group, being higher when submitted to load cycling, and which effect was not found in the groups treated with bioactive primers. It could be concluded that although the bioactive primers did not influenced the BS of adhesive interface, they demonstrated positive results on hybrid layer degradation.

Exploring the roles, effectiveness and impact of health information professionals within evidence based practice

Brettle, A. January 2009 (has links)
This is the thesis (critical appraisal) component of a PhD by Published Works. The overall submission was a portfolio of ten published papers supported by a critical appraisal focusing on two key areas: an exploration of the roles that Health Information Professionals (HIPs) can play within evidence based practice (EBP) and an exploration of the effectiveness and impact of the traditional supportive role played by HIPs within EBP. The published papers are listed and referenced within this document but not contained within it. The majority are available elsewhere within the University of Salford Institutional Repository. Drawing on a model developed from the library literature, the thesis highlights a wide range of supportive and active roles that HIPs can potentially play within EBP. This model is informed and illuminated by the studies within the portfolio that demonstrate how the author has fulfilled a wide range of these roles in practice, and identified a new role within systematic reviews in health and social care. This demonstrates that HIPs can transfer their skills outside their traditional library and information practice domain, thus extending their role and offering a range of professional opportunities. Using a varied range of research methodologies, the thesis also explores the effectiveness and impact of the contribution made by HIPs when using traditional skills to support EBP. Two models are used to illustrate the outcomes to which HIPs contribute. These include improving search skills and providing evidence which can, over the longer term, contribute to policy making and patient care. At present the weight of the evidence presented to support these links is weak. Methodological issues and future research that needs to be addressed to improve the strength of the evidence base are therefore highlighted and discussed.

Real estate taxation Abstract The aim of the diploma thesis is to introduce in detail Act No. 338/1992 Coll., On Real Estate Tax, as amended. The structure of the chapters is usually divided as well as the real estate tax itself on land tax and building and unit tax. A detailed analysis of individual tax elements and an examination of possible de lege ferenda proposals for potencial changes that could be made in the Czech real property tax law are provided. The thesis consists of 8 chapters. In the introductory chapters, the thesis deals with the general characteristics of taxes, the various constructional elements of the tax and the changes made by the recodification of private law, which influenced more than just the title of the real estate tax. The main content of the thesis is in Chapter 3, which gives insight into the theme by giving a detailed introduction of the various elements of the tax. The object of the tax, subject of the tax, tax basis and tax rate are presented. Chapters 4 to 7 deal in detail with tax exemption, tax rate issues, tax administration, and the comparison of the revenue from real estate tax and the revenue from the real estate acquisition tax. Both of these taxes relate to real estates and belong to the category of property taxes. The thesis also deals with a description of the...

Důsledky porušení předpisů o dokazování pro účinnost důkazů / Breach of evidence rules and its consequences for the effectiveness of evidence

Holubcová, Nikola January 2019 (has links)
Breach of evidence rules and its consequences for the effectiveness of evidence Abstract The aim of this diploma thesis is to provide a complex overview of the issue of the legality of evidence in the Czech criminal proceedings. The consideration of the legality of the evidence is viewed as a criterion for evaluation of the evidence. As a result of such criteria, there is a legal consequence - the effectiveness of the evidence, that can be absolute and relative. The diploma thesis consists of 8 chapters, including the introduction and conclusion. The first three chapters are general in nature, and they aim to provide an overview of the rules of evidence and point out mistakes of the lawmakers and inadequacy of the case law in these procedural aspects. I first introduce the terminology. The following chapter is devoted to basic principles that are applied in the rules of evidence. I consider them to be very important as these must be followed in order for the evidence process to be considered lawful. Chapter 4 deals with the introduction of individual phases of the criminal proceedings. Next 2 chapters (chapter 5 and 6) are the core of the thesis as they analyze the legality of the evidence and the criteria used to determine such legality. Next, the effectiveness and nullity is analyzed also in the context...
