Workplace adjustment of an expatriate manager: identifying key components from a social capital perspective

Perustaen tutkimuksen kansainvälisen sopeutumisen teoreettiselle rungolle täydentäen sitä sosiaalisen pääoman teorialla, tämä tutkielma tutkii kuinka johtoasemassa oleva ulkosuomalainen luo hyvin toimivan sosiaalisen verkoston hong kongilaisella työpaikallansa. Tutkielma lähestyy aihetta Nahapietin ja Ghoshalin (1998) kehittämän sosiaalisen pääoman kolmen ulottuvuuden mallin avulla. Tutkielmassa kirjallisuudesta haettua teoriaa käytetään tutkimustavarten tehtyjen haastattelujen analysointiapuna. Tutkimalla sosiaalista pääomaa, kansainvälisen sopeutumisen kirjallisuutta, ekspatriootin perinteisiä menestystekijöitä ja guanxia (kiinalaisten henkilökohtaisia siteitä) tämän tutkimuksen teoriaosuus implikoi, että sosiaalisella pääomalla tulisi olla täydentävä rooli kansainvälisen sopeutumisen kirjallisuudessa. Sosiaalisen pääoman kolmen ulottuvuuden mallia käytetään pohjana empiirisen datan analysointiin. Tutkielman empiiriset tulokset osoittavat, että työpaikan sosiaaliseen verkostoon sopeutuminen liittyy exspatriootin kykyyn käsitellä estäviä ja mahdollistajia sosiaalisen pääoman luontiin vaikuttavia tekijöitä. Lisäksi sopeutuminen vaatii exspatriootin tunnistavan kohdemaalle tyypillisiä exspatriootin menestystekijöitä ja ekspatriootinomia tärkeitä henkilökohtaisia ominaisuuksia.

Holocene Varved Lake Sediments as Records of Palaeoenvironmental Change and Geomagnetic Palaeosecular Variation in Eastern Finland

This dissertation discusses Holocene palaeoenvironmental and palaeomagnetic secular variation (PSV) records reconstructed from sediments preserved in Lake Lehmilampi (63º37´N, 29º06´E) and Lake Kortejärvi (63º37´N, 28º56´E) in eastern Finland. Several piston and freeze cores were obtained from both lakes for varve and magnetic analyses. Sediment samples were impregnated in low-viscosity epoxy and physical parameters of varves, including varve thickness and relative grey-scale values, were recorded using x-ray densitometry combined with semiautomatic digital image analysis. On average, varve records of Lehmilampi and Kortejärvi cover 5122 and 3902 years, respectively. Past solar activity, as estimated by residual ₁₄C data, compares favourably with varve thicknesses from Lehmilampi during the last 2000 years. This indicates the potential of clastic-organic varves to record sensitively climatic variations. Bulk magnetic parameters, including magnetic susceptibility together with natural, anhysteretic and isothermal remanent magnetizations, were measured to describe mineral magnetic properties and geomagnetic palaeosecular variation recorded in the sediments. Main stages in the development of the investigated lakes are reflected in the variations in the mineral magnetic records, sediment lithology and composition. Similar variations in magnetic parameters and sediment organic matter suggest contribution of bacterial magnetite in the magnetic assemblages of Lehmilampi. Inclination and relative declination records yielded largely consistent results, attesting to the great potential of these sediments to preserve directional palaeosecular variation in high resolution. The PSV data from Lehmilampi and Kortejärvi were stacked into North Karelian PSV stack, which may be used for dating homogenous lake sediments in the same regional context. Reconstructed millennial variations in relative palaeointensity results are approximately in agreement with those seen in the absolute palaeointensity data from Europe. Centennial variations in the relative palaeointensity, however, are influenced by environmental changes. Caution is recommended when using varved lake sediments in reconstructing relative palaeointensity.

Internal communication during an organizational change: An ethnographic case study

This study discusses the importance of internal communication during organizational change of a case study company X. The purpose of this study is to find out how to use internal communication effectively during organizational change. This study is an ethnographic cade study where a unique case of an organizational change was chosen as the research object. The theoretical background of this study consists of literature relating to the concepts of communication, organizational communication, organizational change, change management and communication of change. The empirical research conducted for this study is based on an ethnographic research method where data was collected through participant observation, informal interviews and field records in the form of a research diary. The research data was collected between September and December 2015. During this period the researcher was working within the case study organization while observing the internal communication during the organizational change process. Triangulation was used to analyze the research data in order to build a united and theoretical picture of the topic. The study finds that without clear internal communication strategy the effectiveness of communication is ought to be poor, which may lead to resistance of change, lack of trust and lower level of overall job satisfaction. Moreover the study findings highlight the importance of managerial presence during an organizational change process and consistency in using formal and informal communication and utilizing multiple communication channels. Based on the findings of this research the study suggests that during an organizational change process a clear internal communication strategy should be carefully planned and executed. The goals of internal communication should be clearly stated and communicated to the company’s employees. The findings of this study enhance importance of managers promoting sense of belonging, developing awareness of the overall change process and contributing to the manager employee relationships and trust. In addition this study points out the key factors that should be included in the internal change communication strategy which are how to ensure that the communications, both vertical and horizontal, are constant. Future research is however necessary in order to gain a more comprehensive view of the research and wider perspective of the case study. Nevertheless, this study deepens the understanding of how to use internal communication effectively during organizational change.
