This thesis examines the migrationary processes of graduates leaving their home country and their post-migration experiences and aspirations in a receiving state. Using the case study of England, findings are presented from qualitative research with Polish graduates born between the late 1970s and early 1980s, and who moved to England after 2004. It is argued that this generation of Polish migrants is particularly important given the profound impacts of socio-cultural and economic transformation in Poland, tied to the emergence of capitalism, the preparation for accession of Poland to the European Union (EU) and EU citizenship in 2004, on current debates on the geographies of graduate migration within and beyond Europe. Several important findings are revealed by the research. First, it is asserted that perspectives of migration which focus on structure-agency relations (Halfacree, 1995) need to encompass the economic and political aspects of participants sending state at the time of migration, as well as the historical influences on migration decision-making processes. Second, the discussion shows that graduate migration to another country leads to differing approaches to career and life trajectory development after migration and this thesis conceptualises these using the following typology: Continuers , Switchers and Late Awakeners , with dynamism and slippage across the groupings. Third, the findings expose graduate migrant perceptions of becoming and being highly-skilled, and the role of university preparation, and other forms of post-graduate training and potentially strategic acquisitions of citizenship for labour market confidence to compete and undertake professional jobs in Poland and England. Fourth, the thesis stresses that migration is often a first step in graduate migrants life trajectories and it emphasises the importance of a stepping-stone migration , both socially and spatially, and which is embedded within individuals' life-phases and perceptions of home and place. It is argued that this conceptual and geographic contribution to wider studies of graduate migration across countries may have wider resonance to other graduate migrant groups in Europe and beyond.

ABSTRACT Ago, E.K. EU Common Commercial Policy’s Perception by Ghana- Based Businesses. Diploma thesis; Brno: Mendel University, Brno , 2019 This diploma thesis covers extensive investigations into the existing EU-Ghana bilateral trade, and provides recommendations instructive for top managerial decision making regarding how best trade ties between the two organizations will be tightened and ensure effective trade relations. The thesis provides deep insights information that is vital for Ghanaian companies on the EU common commercial policies and the 2016 stepping stone Economic Partnership Agreement. Analyses were based on qualitative and quantitative approaches on general perception by Ghanaian companies about the European Union Economic Partnership Agreement and commercial policy. The questionnaire data has shown that most companies in Ghana are willing to transact business with the EU within a favourable framework of trade. Keywords: CCP, Economic Partnership Agreement, EU, Ghana - Based Companies, Stepping Stone

In the last decades, in most of the OECD countries employment relations have been changing and atypical forms of employment have been spreading rapidly. The “standard contract”, permanent and full-time, has lost importance, replaced by “flexible jobs”, such as fixed-term contracts, temporary work agency employment, variable working hours jobs, on call employment. A debate has been rising on whether atypical jobs, especially short-term contracts, might spur the development of a secondary labour market, in which the unemployed might get trapped in a cycle between dead-end jobs and unemployment. On the other hand, disadvantaged groups excluded from employment by too strict regulations might benefit most from the enhanced flexibility. Chapter 1 introduces this debate, Chapters 2 and 3 shed light on it. I analyse the labour market performance of workers who left unemployment through short-term jobs. I infer what counterfactual labour market performance would have been undertaken if the unemployed had rejected these jobs. In this way, it can be established whether short-term jobs may increase or decrease the chances of having a more stable career later in life, i.e. whether they are “stepping stones” or “dead ends”. I find evidence supporting the stepping stone hypothesis both in Italy and in Belgium. In terms of future job stability, even precarious and unsuccessful jobs are to be preferred to longer searches for directly finding better jobs. Chapter 4 is an identification analysis of the econometric models for duration data that encompass competing risks of exits, consecutive spells, and lagged duration dependence. Finally, Chapter 5 provides a new estimation strategy to look at the effect of past labour market experiences on two aspects of the subsequent job quality: wage and tenure on the job. The methodological novelty consists in jointly modelling labour market durations, transitions, and wages by way of a hazard-function based approach.

La tesi è strutturata in 3 capitoli e analizza gli investimenti e la regolamentazione nel broadband market". Il primo capitolo analizza la letteratura teorica ed empirica sul rapporto tra gli investimenti e la regolamentazione nel settore delle telecomunicazioni. Il secondo capitolo fornisce un'analisi teorica sullo "stepping-stone theory". La terza parte fornisce un'analisi sull'impatto dei diversi regimi normativi per la costruzione della Next Generation Networks. / This dissertation is composed of three papers and discusses the issue of investment and regulation in broadband market. The first paper reviews the specialized but growing branch of the literature. It surveys the relevant theoretical and empirical literature on the relationship between regulation, at both retail and wholesale level, and investment in telecoms infrastructures. Theoretical analyses state that with respect to retail (incentive) regulation, the firm‘s incentive to invest is related to the level of price cap. As for access regulation, mandatory unbundling can possibly discourage firms‘ incentive to invest, but this is not the case for all circumstances because some studies have displayed an opposite (positive) effect on investment. The influence of regulators‘ limited ability to make credible commitment ex ante is not negligible either. Evidence in empirical findings exhibits a certain disunity. The majority concludes that local loop unbundling based on forward-looking cost methodology discourages both ILECs and CLECs from investing in networks, so that the stepping-stone theory is possibly not supported by the data; other findings support the non-negative effect of access regulation on investment. The second paper provides theoretical analysis on the stepping-stone theory. We dynamically model the competition between a vertically-integrated incumbent firm and a facilities-free new entrant in broadband market, where both firms are entitled with investment options: not only can the incumbent decide how much to spend in upgrading its existing network, but also the entrant can choose whether and when to invest on the construction of its own network. The analysis is conducted under three different kinds of competition: pure services-based, pure facilities-based and mixed competition. We find that the entrant's ability to provide value-added services affects the incumbent's investment choice. Our simulation results support the stepping-stone theory that access regulation provides an impetus for the entrant to invest in their own facilities after entering the market based on leased lines. It is also socially desirable because both the overall welfare and the consumer surplus are maximized in a regulated market under mixed competition. The third paper studies impacts of different regulatory regimes on the construction of Next Generation Networks (NGNs). We model the competition between a vertically-integrated incumbent firm and a facilities-free entrant firm in broadband market, where the incumbent has an investment option to upgrade its current network to the NGN. In order to analyze how policy settings affect the incumbent firm‘s investment choice, three kinds of regulatory regimes are discussed: no regulation, partial regulation (only the traditional network is regulated and the NGN is unregulated) and full regulation (both the traditional network and the NGN are regulated). We find that not only the entrant‘s ability to provide value-added services, but also the substitution factor that indexes the decrease in consumers‘ willingness to pay for the traditional service once the investment occurs, affect the incumbent‘s investment choice. Moreover, the comparison of results under different regimes shows that the incumbent invests the most under partial regulation, which sheds some light on impelling the deployment of Next Generation Networks.

Stepping stones are compromised hosts in a network which can be used by hackers and other malicious attackers to hide the origin of connections. Attackers hop from one compromised host to another to form a chain of stepping stones before launching attack on the actual victim host. Various timing and content based detection techniques have been proposed in the literature to trace back through a chain of stepping stones in order to identify the attacker. This has naturally led to evasive strategies such as shaping the trac di erently at each hop. The evasive techniques can also be detected. Our study aims to adapt some of the existing stepping stone detection and antievasion techniques to software-dened networks which use network function virtualization. We have implemented the stepping-stone detection techniques in a simulated environment and use sFlow for the trac monitoring at the switches. We evaluate the detection algorithms on di erent network topologies and analyze the results to gain insight on the e ectiveness of the detection mechanisms. The selected detection techniques work well on relatively high packet sampling rates. However, new solutions will be needed for large SDN networks where the packet sampling rate needs to be lower.

This thesis studies the role of new firms in the labour market and uses Swedish data to analyze labour mobility in new firms, including both transitions of workers into and from new firms. In particular, it focuses on employees’ wages in new firms and post-new firm employment labour market outcomes as transitions into long-term employment and entrepreneurship.  This thesis consists of four essays. The first two essays concern labour mobility into new firms. The last two essays focus on post-new firm employment mobility. The first essay explores the role of new firms as an entry point into the labour market for individuals with little (or no) labour market experience. The findings show that the wage penalty found in previous research, which includes more heterogeneous groups of employees, decreases once the focus is solely on labour market entrants.  The second essay investigates whether there is a wage penalty for being employed at a new firm if the individual employee’s experience and status in the labour market are taken into account; this essay focuses on individuals who decide to switch jobs. The findings show that there is a wage penalty for being employed at a new firm; however, considering a random selection into new firms may underestimate the wage differentials. The third essay studies the role that new firms play for the career path of their employees. In particular, this paper analyzes whether short-term employment in new firms (employment lasting less than one year) may serve as a stepping stone toward long-term employment (at least two years of employment with the same employer) for non-employed individuals. The findings indicate that short-term employment in new firms may serve as a stepping stone toward long-term employment. The fourth paper examines the new firm effect on entrepreneurship, which the findings indicate is positive and statistically significant; this effect remains even after controlling for a worker's ability and shows that employees with both high and low levels of ability may transition to entrepreneurship. / <p>QC 20160916</p>

Bakgrund Revisionsbranschen   präglas av en hög personalomsättning vilket   har resulterat i att antalet kvalificerade revisorer sedan 2005 minskat med 20 %. Detta   är ett problem för revisionsbyråer då de   satsar mycket resurser på anställda   som sedan lämnar innan de hunnit uppnå auktorisation. Representanter   från Big 4-byråer beskriver att   revisorsassistenter erhåller attraktiva kompetenser som är intressanta för   rekryterare i andra branscher. Revisorsassistenter är medvetna om detta och   använder således yrket som en språngbräda. Syfte Syftet med studien är att utforska varför ett   arbete som revisorsassistent   fungerar som en karriärmässig språngbräda. Metod Studien har tillämpat   en intervjumetod med en huvudsaklig deduktiv ansats med induktiva inslag. För   datainsamlingen har sammantaget 17 semistrukturerade intervjuer genomförts   med respondenter från fyra olika intervjugrupper. Slutsats På grund av den stora   mängden utbildning som ges på revisionsbyråer erhåller revisorsassistenter en   rad kunskapsmässiga kompetenser som är attraktiva för rekryterare utanför   branschen. Revisorsassistenter blir även attraktiva till följd av branschens   arbetsklimat, som präglas av en intensiv högsäsong som bidrar till att   revisorsassistenter lär sig hantera stress och arbeta på ett effektivt sätt.   Studien indikerar även att revisorsassistenter utvecklar en god social   kompetens som värderas högt av rekryterare. / Introduction The audit industry is affected by a high employee turnover   that has resulted in a 20 % loss of certified public accountants since the year 2005. This is a problem for audit firms since they invest a lot of resources in educating their employees, who in turn leave the industry before they achieve their authorization. Representatives from the Big 4 describe that audit assistants acquire attractive knowledge which are appealing for recruiters in other lines of business. Audit assistants are aware of this which results in them using the job as a stepping stone in to other industries. Purpose    The purpose of the study is to examine why an employment as an audit assistant works as a stepping stone in to other industries. Method The study applies an interview method with a mainly deductive approach. To collect data the authors have carried out 17 interviews in total, with respondents from four different interview groups. Conclusion The findings of the study is that the large amount of internal education that the firms provide results in audit assistants gaining lots of attractive knowledge. Audit assistants also become attractive because of the industry’s work climate. The audit industry is affected by an intense peak season which teaches the audit assistants to cope with stress and to work efficient. The study also  indicates  that  audit  assistants  develop  social skills which are highly attractive in the eyes of recruiters.

The Swedish regulation concerning fixed-term contract has been a topic for discussion during the last decade. It has been criticised for not following the council’s directive 1999/70/EG on the measures to prevent the abuse of fixed-term contracts. Since 2016 the regulation has changed. It has changed in order to have the legislation within the purpose and measures set in the fixed-term directive. This essay aims to clarify whether the new Swedish legislation is in accordance with the framework agreement attached to the directive on fixed-term contracts. This will be done by analysing the measures established in the framework agreement and the purpose of the directive, then compare the result with the Swedish legislation. This part of the essay will be written using the legal dogmatic methodology. Since fixed-term contracts are more common among young people this essay will focus on how fixed-term contract, and regulations on fixed-term contracts, will affect the position of young people in the labour market. It is obvious that there are some difficulties to harmonize a legislation that suits all the social partners on the labour market. In fact, it can almost be impossible. By illuminate the political discussion regarding the use of fixed-term contracts it will help to understand why this matter is so complex and how it can be a stepping stone or a dead-end job. This will be done with a legal policy method.
