The potential of social networking sites in inpatriate adjustment

People make up one of the most important resources for a corporation and therefore it has to continuously seek an ever more diverse and international workforce. Inpatriation is another way of utilizing foreign expertise in a corporation. An inpatriate refers to a person that is on an international assignment at the headquarters of a corporation, where they have been sent either from a subsidiary abroad or from a third country outside the corporation. Strengthening the social network of the inpatriate and their family contributes to the adjustment process and furthermore the success of the work assignment. As social networking sites are currently the fastest developing personal networking tools in the world, it is interesting to see how they can help in inpatriate adjustment. The objective of this thesis is to explore the potential of social networking sites (SNS) in inpatriate adjustment. The main objective can be divided into three sub objectives: 1. What is SNS used for during the inpatriate assignment? 2. What are the inpatriates’ motivations to use SNS? 3. Could the three facets of adjustment (work, interaction and general) be gained through SNS? This qualitative study utilizes the theme interview data collection method and the thematic analysis approach for analysing the interview data. From the interviews with five Indian inpatriates in Finland the most mentioned uses of SNS were related to participating (sharing opinions, recommendations and discussing things and connecting to friends, family and colleagues) and consuming (collecting information for work and free time), the least mentioned use of SNS was producing (posting videos, photos and updates). An interesting finding was that the five interviewees did not use SNS for purely entertainment motives at all during their assignment. This thesis found that all three facets of adjustment could potentially be gained through SNS.

Knowledge, processes and relationships in organizational change: Understanding how to facilitate management of intellectual capital in diverse organization structures and cultures.

This study examined relationships of organizational dependencies, change management and developed intellectual knowledge resources, in different intellectual capital based development programs on ICT-sector. Study was carried out in a research context, where high degree of external organizational contingencies existed and lots of changes in several development programs had taken place in the last years. From a scientific perspective the main contribution was that evidence between relationships of organizational dependencies, change model portfolio and developed knowledge resources could be suggested. From managerial perspective the primary implication was that in situations where sustainable competitive advantage is pursued by means of increasing knowledge based productivity of labor, firms should seek to pursue organizational settings where external dependencies have minimal amount of effect.

Improving customer service by identifying critical success factors and utilizing business process outsourcing

Consumers increasingly demand convenience when dealing with companies and therefore it is important to provide professional, diverse and speedy service via customer’s preferred communication channel. These interactions between the customer service and customer have a critical role in customer’s future purchasing decisions. Those customers who don't receive satisfactory customer service are willing to do business with another company that charges more but offers better customer service. This study identifies the critical success factors for the customer service in order to improve the customer service according to the company’s mission and meet customer expectations. Case study is used as a research method and data is collected via observation, archival records and interviews during a time span of fourteen months. The analysis suggests three critical success factors: voice support, scalable and flexible customer service and customer service champions. The study further analyzes the improvement measures according to the critical success factors concluding the Business Process Outsourcing to be the most proper to proceed with. As a conclusion of the study, critical success factors enable achieving the goals of the customer service and align operations according to the company’s mission. Business Process Outsourcing plays important role in improving the customer service by allowing fast expansion of new service offering and obtaining specialized workforce.

Communicative Purposes of Press Releases Announcing Reduction in Workforce

Tämä tutkielma käsittelee kaupallisten yhtiöiden julkaisemia lehdistötiedotteita, joissa ilmoitetaan henkilöstövähennyksistä. Erityisenä tutkimuskohteena ovat lehdistötiedotteiden informatiiviset ja promotionaaliset päämäärät ja tarkoitukset sekä näiden päämäärien ja tarkoitusten ilmentyminen tekstin retorisen rakenteen, valittujen retoristen strategioiden sekä leksikaalisten ja kieliopillisten valintojen kautta. Tutkimuksen aineisto koostuu 50 englanninkielisestä lehdistötiedotteesta, jotka sisältävät ilmoituksen henkilöstövähennyksistä. Lehdistötiedotteet kerättiin yritysten verkkosivuilta. Tutkimuksen teoreettisena viitekehityksenä toimivat soveltavan kielentutkimuksen alalla erityisesti ammattikielentutkimuksessa (ESP, English for Specific Purposes) laajalti käytetty Swalesin (1990) tekstilajia (genre) koskeva määritelmää ja Bhatian (1993) kehittämä geneerisen analyysin malli. Ennen aineiston kielitieteellistä analysointia tutkimuksessa perehdyttiin Bhatian (1993) mallin mukaisesti lehdistötiedotteiden historiaan, kohdeyleisöihin, diskurssiyhteisöön ja sen tuottamiin muihin tekstilajeihin, aikaisempiin lehdistotiedotteita käsitteleviin kielitieteellisiin tutkimuksiin sekä erityisesti yritysten henkilövähennyksiin liittyvään tilannekontekstiin. Kielitieteellisessä analyysissä tutkittavista teksteistä tunnistettiin kahdeksan retorista vaihetta (move), jotka olivat tyypillisiä tutkituille teksteille. Kunkin retorisen vaiheen yksittäiset ilmentymät koottiin yhteen erillisiksi aineistoiksi, joista pyrittiin tunnistamaan kullekin vaiheelle tyypilliset retoriset strategiat sekä toistuvat leksikaaliset ja kieliopilliset valinnat. Tutkimuksessa todettiin, että vaikka tutkittujen lehdistötiedotteiden pääasiallinen tarkoitus oli yhtiön toiminnasta tiedottaminen, niillä oli myös promotionaalinen päämäärä, joka ilmeni mm. pyrkimyksenä välittää yhtiöstä mahdollisimman positiivinen kuva eri kohdeyleisöille, erityisesti sijoittajille. Tämän positiivisen kuvan välittämiseen käytettyjä keinoja olivat mm. odotettavissa olevien saavutusten korostaminen, ulkoisten tekijöiden nimeäminen nykyisen tilanteen aiheuttajaksi, passiivin käyttö sekä erilaiset yrityksen julkisen kuvan säilyttämiseen pyrkivät (face-saving) strategiat.

Roles of leadership in complex environments : Enhancing Knowledge Flows in Organisational Constellations through Practice-Based Innovation Processes

Global challenges, complexity and continuous uncertainty demand development of leadership approaches, employees and multi-organisation constellations. Current leadership theories do not sufficiently address the needs of complex business environments. First of all, before successful leadership models can be applied in practice, leadership needs to shift from the industrial age to the knowledge era. Many leadership models still view leadership solely through the perspective of linear process thinking. In addition, there is not enough knowledge or experience in applying these newer models in practice. Leadership theories continue to be based on the assumption that leaders possess or have access to all the relevant knowledge and capabilities to decide future directions without external advice. In many companies, however, the workforce consists of skilled professionals whose work and related interfaces are so challenging that the leaders cannot grasp all the linked viewpoints and cross-impacts alone. One of the main objectives of this study is to understand how to support participants in organisations and their stakeholders to, through practice-based innovation processes, confront various environments. Another aim is to find effective ways of recognising and reacting to diverse contexts, so companies and other stakeholders are better able to link to knowledge flows and shared value creation processes in advancing joint value to their customers. The main research question of this dissertation is, then, to seek understanding of how to enhance leadership in complex environments. The dissertation can, on the whole, be characterised as a qualitative multiple-case study. The research questions and objectives were investigated through six studies published in international scientific journals. The main methods applied were interviews, action research and a survey. The empirical focus was on Finnish companies, and the research questions were examined in various organisations at the top levels (leaders and managers) and bottom levels (employees) in the context of collaboration between organisations and cooperation between case companies and their client organisations. However, the emphasis of the analysis is the internal and external aspects of organisations, which are conducted in practice-based innovation processes. The results of this study suggest that the Cynefin framework, complexity leadership theory and transformational leadership represent theoretical models applicable to developing leadership through practice-based innovation. In and of themselves, they all support confronting contemporary challenges, but an implementable method for organisations may be constructed by assimilating them into practice-based innovation processes. Recognition of diverse environments, their various contexts and roles in the activities and collaboration of organisations and their interest groups is ever-more important to achieving better interaction in which a strategic or formal status may be bypassed. In innovation processes, it is not necessarily the leader who is in possession of the essential knowledge; thus, it is the role of leadership to offer methods and arenas where different actors may generate advances. Enabling and supporting continuous interaction and integrated knowledge flows is of crucial importance, to achieve emergence of innovations in the activities of organisations and various forms of collaboration. The main contribution of this dissertation relates to applying these new conceptual models in practice. Empirical evidence on the relevance of different leadership roles in practice-based innovation processes in Finnish companies is another valuable contribution. Finally, the dissertation sheds light on the significance of combining complexity science with leadership and innovation theories in research.

Diverse effects of renal denervation on ventricular hypertrophy and blood pressure in DOCA-salt hypertensive rats

Cardiac hypertrophy that accompanies hypertension seems to be a phenomenon of multifactorial origin whose development does not seem to depend on an increased pressure load alone, but also on local growth factors and cardioadrenergic activity. The aim of the present study was to determine if sympathetic renal denervation and its effects on arterial pressure level can prevent cardiac hypertrophy and if it can also delay the onset and attenuate the severity of deoxycorticosterone acetate (DOCA)-salt hypertension. DOCA-salt treatment was initiated in rats seven days after uninephrectomy and contralateral renal denervation or sham renal denervation. DOCA (15 mg/kg, sc) or vehicle (soybean oil, 0.25 ml per animal) was administered twice a week for two weeks. Rats treated with DOCA or vehicle (control) were provided drinking water containing 1% NaCl and 0.03% KCl. At the end of the treatment period, mean arterial pressure (MAP) and heart rate measurements were made in conscious animals. Under ether anesthesia, the heart was removed and the right and left ventricles (including the septum) were separated and weighed. DOCA-salt treatment produced a significant increase in left ventricular weight/body weight (LVW/BW) ratio (2.44 ± 0.09 mg/g) and right ventricular weight/body weight (RVW/BW) ratio (0.53 ± 0.01 mg/g) compared to control (1.92 ± 0.04 and 0.48 ± 0.01 mg/g, respectively) rats. MAP was significantly higher (39%) in DOCA-salt rats. Renal denervation prevented (P>0.05) the development of hypertension in DOCA-salt rats but did not prevent the increase in LVW/BW (2.27 ± 0.03 mg/g) and RVW/BW (0.52 ± 0.01 mg/g). We have shown that the increase in arterial pressure level is not responsible for cardiac hypertrophy, which may be more related to other events associated with DOCA-salt hypertension, such as an increase in cardiac sympathetic activity

Collective Action in Commons: Its Diverse Ends and Consequences

Collective Action in Commons: Its Diverse Ends and Consequences explores new ways in which collective action theories can contribute to our understanding of natural resource management, especially the management of common-pools. Combining classical collective action theories and lessons from earlier empirical works, the study shows that cooperation among resource users is not only a possible solution to “the tragedy of the commons”, but it can be a part of the problem as well. That is, successful cooperation may increase the likelihood of resource depletion, for example, through more effective resource utilization or collusion against sanctioning and monitoring systems. The study also explores how analytic narratives can be used to tell the story behind problems of resource use and their solutions, including the diverse roles of cooperation.

Extracellular matrix molecules play diverse roles in the growth and guidance of central nervous system axons

Axon growth and guidance represent complex biological processes in which probably intervene diverse sets of molecular cues that allow for the appropriate wiring of the central nervous system (CNS). The extracellular matrix (ECM) represents a major contributor of molecular signals either diffusible or membrane-bound that may regulate different stages of neural development. Some of the brain ECM molecules form tridimensional structures (tunnels and boundaries) that appear during time- and space-regulated events, possibly playing relevant roles in the control of axon elongation and pathfinding. This short review focuses mainly on the recognized roles played by proteoglycans, laminin, fibronectin and tenascin in axonal development during ontogenesis.

Understanding value congruence : a sport organization case study

With the recent growth in cultural complexity, many organizations are faced with increasingly diverse employee pools. Gaining a greater understanding of the values that employees possess is the first step in effectively satisfying their needs and achieving a more productive workforce (lung & Avolio, 2000). Values playa significant role in influencing individual behaviours. It is therefore necessary to assess the qualities of employee value systems and directly link them to the values of the organization. The importance of values and value congruence has been emphasized by many organizational behaviour researchers (cf. Adkins & Caldwell, 2004; Erdogan, Kraimer, & Liden, 2004; Jung & Avolio, 2000; Rokeach, 1973); however the emphasis on value studies remains fairly stagnant within the sport industry (Amis, Slack, & Hinings, 2002). In order to examine the realities that were constructed by the participants in this study a holistic view of the impact of values within a specific sport organization were provided. The purpose of this case study was to examine organizational and employee values to understand the effects of values and value congruence on employee behaviours within the context of a large Canadian sport organization. A mUltiple methods case study approach was adopted in order to fully serve the purpose and provide a comprehensive view of the organization being examined. Document analysis, observations, surveys, as well as semi-structured interviews were conducted. The process allowed for triangulation and confirmability of the findings. Each method functioned to create an overarching understanding of the values and value congruence within this organization. The analysis of the findings was divided into qualitative and quantitative sections. The qualitative documents were analyzed twice, once manually by the researcher and once via AtIas.ti Version 4 (1998). The a priori and emergent coding that took place was based on triangulating the findings and uncovering common themes throughout the data. The Rokeach Value Survey (1973) that was incorporated into the survey design of the study was analyzed using descriptive statistics, as well as Mann-Whitney U, and Kruskal Wallis formulas. These were deemed appropriate for analysis given the non-parametric nature of the survey instrument (Kinnear & Gray, 2004). The quantitative survey served to help define the values and value congruence that was then holistically examined through the qualitative interviews, document analyses, and observations. The results of the study indicated incongruent value levels between employees and those stated or perceived as the organization's values. Each finding demonstrated that varying levels of congruence may have diverse affects on individual behaviours. These behaviours range from production levels to interactions with fellow employees to turnover. In addition to the findings pertaining to the research questions, a number of other key issues were uncovered regarding departmentalization, communication, and board relations. Each has contributed to a greater understanding of the organization and has created direction for further research within this area of study.

Locating home : the diverse experiences of recent newcomer youth and first generation youth within Ontario's education system

This study has found that youth who or whose parents had left their home country for fear-based reasons were less involved within their school and wider community than youth who left or whose parents left for reasons concerning their social mobility. Many existing studies focus on the challenges newcomer youth experience within the education system (see Anisef, Brown, Phythian, & Sweet, 2010), however through the use of qualitative methodologies this study expanded on the current literature by further examining why it is some youth are successful in overcoming such challenges, while others are not. This study supported what has been demonstrated in the literature regarding challenges faced by newcomer youth and resources to address such challenges. Despite challenges experienced within the education system, youth planned to complete secondary school and attend a postsecondary institution. However, not all youth anticipated remaining in Canada upon completion of their education, with youth or youth whose parents left their home country for fear-based reasons frequently discussing the possibility of returning to their or their parents' home country. Thus, perhaps these youth were less involved within their school, as their goal was not necessarily to establish or maintain connections within their community as they may have viewed residing in Canada as temporary. This finding has important implications, as there are benefits to involvement in extracurricular activities, which may assist youth in overcoming challenges encountered within the education system. Therefore, it would seem that youth who had or whose parents had left their home country for reasons concerning their social mobility may have be at an advantage within the education system with respect to their involvement in school. Perhaps then this differential involvement may at least partially explain why it is some newcomer youth are able to overcome challenges they experience in the education system, while others are not. Both policy and theoretical implications are discussed.

Poverty and Education: Preparing Teacher Candidates for Economically Diverse Classroom Environments

The poverty rate in Ontario affects approximately 1 in 6 children. Consequently, many classrooms in the province include students who come from poverty, and teachers are faced with the challenge of providing an equitable education to students who come from economically diverse backgrounds. Because student poverty in our education system is so prevalent, this challenge exists also for teacher candidates who enter the education system and complete their practicums in classrooms that often include students from impoverished backgrounds. This project examined issues of poverty and education and developed a workshop to assist teacher candidates to develop knowledge in this area. The project combined existing pedagogical approaches with participants’ recommendations and developed a workshop that could be delivered to Faculty of Education students. The workshop addresses poverty, the relationship between poverty and education, student academic achievement and well-being, and the relationship between school and home. The goal and hope of the workshop is that teacher candidates will be better prepared when working in economically diverse school environments.

Systematics and floral evolution of the Dialiinae (Caesalpinioideae), a diverse lineage of tropical legumes

Le clade Dialiinae représente l’une des premières lignées de la sous-famille Caesalpinioideae des Leguminosae. Il se compose de 17 genres (environ 90 espèces), avec des taxons qui sont répandus dans toutes les régions tropicales du monde. Morphologiquement, le groupe comprend un assemblage divers de taxons qui peut représenter une «phase expérimentale» dans l’évolution florale des légumineuses. Différents représentants du clade présentent de la poly-, mono-, et asymétrie, et semblent avoir subi un haut degré de perte d’organe, produisant, dans certains cas, des fleurs extrêmement réduites qui sont à peine reconnaissables comme appartenant à la famille des légumineuses. Afin d’obtenir une image plus claire de l’évolution florale du clade Dialiinae, une phylogénie bien résolue et bien soutenue est nécessaire. Dans le but de créer une telle phylogénie, un total de 37 échantillons d’ADN des Dialiinae a été séquencé pour deux régions chloroplastiques, soit rps16 et trnL. De plus, une étude morphologique complète a été réalisée. Un total de 135 caractères végétatifs et reproductifs a été évalué pour 79 espèces de Dialiinae et pour quatre groupes externes. Les analyses phylogénétiques ont d’abord été effectuées sur un groupe restreint de taxons pour lesquels les trois types de données étaient disponibles. Les nœuds fortement soutenus de cette phylogénie ont ensuite été utilisés comme contrainte pour une seconde analyse de parcimonie avec les données morphologiques d’un ensemble plus important de taxons. Les caractères morphologiques ont été optimisés sur l’un des arbres les plus parcimonieux de cette seconde analyse. Un certain nombre de nouvelles relations au niveau de l’espèce ont été résolues, créant une image plus claire quant à l’évolution de la forme florale dans le temps, particulièrement pour les genres Labichea et Dialium. En plus de leur morphologie florale mature diverse, les Dialiinae sont également très variables dans leur ontogénèse florale, affichant à la fois la perte et la suppression des organes, et présentant une variété de modes d’initiation d’organes. Afin de construire une image plus complète du développement floral et de l’évolution dans ce clade, l’ontogénèse florale de plusieurs espèces non documentées à ce jour a été étudiée. La série complète du développement a été compilée pour six espèces de Dialiinae; quatre de Dialium, ainsi que Poeppigia procera et Mendoravia dumaziana. Le mode et le moment de l’initiation des organes étaient pour la plupart uniforme pour toutes les espèces de Dialium étudiés. Tant pour ce qui est des gains ou des pertes d’organes chez Dialium, une tendance est apparente – l’absence d’organe abaxial. Que ce soit pour les sépales ou les étamines, les gains se produisent toujours en position médiane adaxiale, tandis que les étamines et les pétales perdus sont toujours les organes les plus ventraux. Les taxons étudiés ici illustrent le manque apparent de canalisation du développement observé chez les Caesalpinioideae. Cette plasticité ontogénétique est le reflet de la diversité morphologique au niveau des fleurs tel qu’observée dans l’ensemble de la sous-famille. Une des espèces de Dialiinae, Apuleia leiocarpa, produit une inflorescence andromonoïque, une caractéristique qui est unique en son clade et rare dans les légumineuses dans son ensemble. La microscopie optique et électronique ont été utilisées pour entreprendre une étude détaillée de la morphologie florale de ce taxon. On a constaté que tandis que les fleurs hermaphrodites produisent un seul carpelle et deux étamines, les fleurs staminées produisent trois étamines sans toutefois montrer signe de développement du carpelle. Les inflorescences semblent produire près de quatre fois plus de fleurs staminées que de fleurs hermaphrodites, lesquelles occupent toujours la position centrale de l’inflorescence cymeuse. Ce ratio élevé mâle/bisexuel et la détermination précoce du sexe chez Apuleia sont rares chez les Caesalpinioideae, ce qui suggère que l’andromonoecie se développe dans ce genre comme un moyen d’accroître la dispersion du pollen plutôt qu’en réponse à des limitations de ressources.

Effects of diverse plant species on the bioavailability of contaminants in soil

La phytoremédiation constitue une technologie alternative pour le traitement de sols contaminés en métaux. Toutefois, la biodisponibilité des métaux dans le sol peut limiter l’efficacité de cette approche. Nous émettons l’hypothèse que diverses espèces de plante, caractérisées par systèmes racinaires différents, peuvent affecter différemment la biodisponibilité des éléments traces (ET) dans le sol. Une étude utilisant un dispositif expérimental en bloc aléatoire complet avec cinq réplicats a été conduite entre le 6 juin et le 3 septembre 2014, sur le site du Jardin botanique de Montréal. Dans ce contexte, l’impact de la présence de huit espèces de plantes, herbacées ou ligneuses, sur le pool labile de six métaux (Ag, Cu, Pd, Zn, Ni et Se) dans la rhizosphère de celles-ci a été étudié. Après trois mois de culture, la biomasse aérienne et souterraine de chaque espèce a été mesurée et la concentration en ET dans les tissus des plantes a été analysée. La fraction labile de ces ET dans la rhizosphère (potentiellement celle qui serait biodisponible) de même que d’autres paramètres édaphiques (le pH, la conductivité, le pourcentage de matière organique et le carbone organique dissous (COD)) ont aussi été mesurés et comparés en fonction de la présence d’une ou l’autre des espèces utilisées. Les résultats montrent que pour la plupart des plantes testées, les plus fortes concentrations en ET ont été trouvées dans les racines alors que les plus faibles niveaux s’observaient dans les parties aériennes, sauf pour le Ni dans le Salix nigra. Ceci suggère que le Ni peut être extrait du sol par des récoltes régulières des tiges et des feuilles de cette espèce de saule. Les pools labiles de l’Ag, Ni et du Cu dans la rhizosphère étaient significativement et différemment affectés par la présence des plantes. Toutefois, la présence des plantes testées n’a pas affecté certains paramètres clés de la rhizosphère (ex. le pH, conductivité, et le pourcentage de matière organique). À l’opposé, les niveaux de COD dans la rhizosphère de toutes les plantes testées se sont révélés supérieurs en comparaison des témoins (sols non plantés). De plus, une corrélation positive a pu être établie entre la concentration disponible du Ni et la concentration en COD. Une relation similaire a été déterminée pour le Cu. Ceci suggère que certains systèmes racinaires pourraient modifier les niveaux de COD et avoir un impact indirect sur les pools labiles des ET dans le sol.
