Addiction and arousal: the hypocretin connection

The hypocretins, also known as orexins, are two neuropeptides now commonly described as critical components to maintain and regulate the stability of arousal. Several lines of evidence have raised the hypothesis that hypocretin-producing neurons are part of the circuitries that mediate the hypothalamic response to acute stress. Intracerebral administration of hypocretin leads to a dose-related reinstatement of drug and food seeking behaviors. Furthermore, stress-induced reinstatement can be blocked with hypocretin receptor 1 antagonism. These results, together with recent data showing that hypocretin is critically involved in cocaine sensitization through the recruitment of NMDA receptors in the ventral tegmental area, strongly suggest that activation of hypocretin neurons play a critical role in the development of the addiction process. The activity of hypocretin neurons may affect addictive behavior by contributing to brain sensitization or by modulating the brain reward system. Hypocretinergic cells, in coordination with brain stress systems may lead to a vulnerable state that facilitates the resumption of drug seeking behavior. Hence, the hypocretinergic system is a new drug target that may be used to prevent relapse of drug seeking

Consommation de cannabis : quels sont les risques ?

Abstract - Cannabis: what are the risks ? Cannabinoids from cannabis have a dual use and display often opposite pharmacological properties depending on the circumstances of use and the administered dose. Cannabinoids constitute mainly a recreative or addictive substance, but also a therapeutic drug. They can be either neurotoxic or neuroprotector, carcinogenic or an anti-cancer drug, hyperemetic or antiemetic, pro-inflammatory or anti-inflammatory... Improvement in in-door cultivation techniques and selection of high yield strains have resulted in a steadily increase of THC content. Cannabis is the most frequently prohibited drug used in Switzerland and Western countries. About half of teenagers have already experimented cannabis consumption. About 10% of cannabis users smoke it daily and can be considered as cannabis-dependant. About one third of these cannabis smokers are chronically intoxicated. THC, the main psychoactive drug interacts with the endocannnabinoid system which is made of cellular receptors, endogenous ligands and a complex intra-cellular biosynthetic, degradation and intra-cellular messengers machinery. The endocannabinoid system plays a major role in the fine tuning of the nervous system. It is thought to be important in memory, motor learning, and synaptic plasticity. At psychoactive dose, THC impairs psychomotor and neurocognitive performances. Learning and memory abilities are diminished. The risk to be responsible of a traffic car accident is slightly increased after administration of cannabis alone and strongly increased after combined use of alcohol and cannabis. With the exception of young children, cannabis intake does not lead to potentially fatal intoxication. However, cannabis exposure can act as trigger for cardiovascular accidents in rare vulnerable people. Young or vulnerable people are more at risk to develop a psychosis at adulthood and/or to become cannabis-dependant. Epidemiological studies have shown that the risk to develop a schizophrenia at adulthood is increased for cannabis smokers, especially for those who are early consumers. Likewise for the risk of depression and suicide attempt. Respiratory disease can be worsen after cannabis smoking. Pregnant and breast-feeding mothers should not take cannabis because THC gets into placenta and concentrates in breast milk. The most sensitive time-period to adverse side-effects of cannabis starts from foetus and extends to adolescence. The reason could be that the endocannabinoid system, the main target of THC, plays a major role in the setup of neuronal networks in the immature brain. The concomitant use of other psychoactive drugs such as alcohol, benzodiazepines or cocaine should be avoided because of possible mutual interactions. Furthermore, it has been demonstrated that a cross-sensitisation exists between most addictive drugs at the level of the brain reward system. Chronic use of cannabis leads to tolerance and withdrawals symptoms in case of cannabis intake interruption. Apart from the aforementioned unwanted side effects, cannabis displays useful and original medicinal properties which are currently under scientific evaluation. At the moment the benefit/risk ratio is not yet well assessed. Several minor phytocannabinoids or synthetic cannabinoids devoid of psychoactive properties could find their way in the modern pharmacopoeia (e.g. ajulemic acid). For therapeutic purposes, special cannabis varieties with unique cannabinoids composition (e.g. a high cannabidiol content) are preferred over those which are currently used for recreative smoking. The administration mode also differs in such a way that inhalation of carcinogenic pyrolytic compounds resulting from cannabis smoking is avoided. This can be achieved by inhaling cannabis vapors at low temperature with a vaporizer device. Résumé Les cannabinoïdes contenus dans la plante de cannabis ont un double usage et possèdent des propriétés opposées suivant les circonstances et les doses employées. Les cannabinoïdes, essentiellement drogue récréative ou d'abus pourraient, pour certains d'entre eux, devenir des médicaments. Selon les conditions d'utilisation, ils peuvent être neurotoxiques ou neuroprotecteurs, carcinogènes ou anticancéreux, hyper-émétiques ou antiémétiques, pro-inflammatoires ou anti-inflammatoires... Les techniques de culture sous serre indoor ainsi que la sélection de variétés de cannabis à fort potentiel de production ont conduit à un accroissement notable des taux de THC. Le cannabis est la drogue illégale la plus fréquemment consommée en Suisse et ailleurs dans le monde occidental. Environ la moitié des jeunes ont déjà expérimenté le cannabis. Environ 10 % des consommateurs le fument quotidiennement et en sont devenus dépendants. Un tiers de ces usagers peut être considéré comme chroniquement intoxiqué. Le THC, la principale substance psychoactive du cannabis, interagit avec le "système endocannabinoïde". Ce système est composé de récepteurs cellulaires, de ligands endogènes et d'un dispositif complexe de synthèse, de dégradation, de régulation et de messagers intra-cellulaires. Le système endocannabinoïde joue un rôle clé dans le réglage fin du système nerveux. Les endocannabinoïdes régulent la mémorisation, l'apprentissage moteur et la plasticité des liaisons nerveuses. À dose psychoactive, le THC réduit les performances psychomotrices et neurocognitives. Les facultés d'apprentissage et de mémorisation sont diminuées. Le risque d'être responsable d'un accident de circulation est augmenté après prise de cannabis, et ceci d'autant plus que de l'alcool aura été consommé parallèlement. À l'exception des jeunes enfants, la consommation de cannabis n'entraîne pas de risque potentiel d'intoxication mortelle. Toutefois, le cannabis pourrait agir comme facteur déclenchant d'accident cardiovasculaire chez de rares individus prédisposés. Les individus jeunes, et/ou vulnérables ont un risque significativement plus élevé de développer une psychose à l'âge adulte ou de devenir dépendant au cannabis. Des études épidémiologiques ont montré que le risque de développer une schizophrénie à l'âge adulte était augmenté pour les consommateurs de cannabis et ceci d'autant plus que l'âge de début de consommation était précoce. Il en va de même pour le risque de dépression. Les troubles respiratoires pourraient être exacerbés par la prise de cannabis. Les femmes enceintes et celles qui allaitent ne devraient pas consommer de cannabis car le THC traverse la barrière hémato-placentaire, en outre, il se concentre dans le lait maternel. La période de la vie la plus sensible aux effets néfastes du cannabis correspond à celle allant du foetus à l'adolescent. Le système endocannabinoïde sur lequel agit le THC serait en effet un acteur majeur orchestrant le développement des réseaux neuronaux dans le cerveau immature. La prise concomitante d'autres psychotropes comme l'alcool, les benzodiazépines ou la cocaïne conduit à des renforcements mutuels de leurs effets délétères. De plus, il a été montré l'existence d'une sensibilité croisée pour la majorité des psychotropes qui agissent sur le système de la récompense, le cannabis y compris, ce qui augmente ainsi le risque de pharmacodépendance. La prise régulière de doses élevées de cannabis entraîne l'apparition d'une tolérance et de symptômes de sevrage discrets à l'arrêt de la consommation. À part les effets négatifs mentionnés auparavant, le cannabis possède des propriétés médicales originales qui sont l'objet d'études attentives. Plusieurs cannabinoïdes mineurs naturels ou synthétiques, comme l'acide ajulémique, pourraient trouver un jour une place dans la pharmacopée. En usage thérapeutique, des variétés particulières de cannabis sont préférées, par exemple celles riches en cannabidiol non psychoactif. Le mode d'administration diffère de celui utilisé en mode récréatif. Par exemple, la vaporisation des cannabinoïdes à basse température est préférée à l'inhalation du "joint".

A common biological basis of obesity and nicotine addiction.

Smoking influences body weight such that smokers weigh less than non-smokers and smoking cessation often leads to weight increase. The relationship between body weight and smoking is partly explained by the effect of nicotine on appetite and metabolism. However, the brain reward system is involved in the control of the intake of both food and tobacco. We evaluated the effect of single-nucleotide polymorphisms (SNPs) affecting body mass index (BMI) on smoking behavior, and tested the 32 SNPs identified in a meta-analysis for association with two smoking phenotypes, smoking initiation (SI) and the number of cigarettes smoked per day (CPD) in an Icelandic sample (N=34,216 smokers). Combined according to their effect on BMI, the SNPs correlate with both SI (r=0.019, P=0.00054) and CPD (r=0.032, P=8.0 × 10(-7)). These findings replicate in a second large data set (N=127,274, thereof 76,242 smokers) for both SI (P=1.2 × 10(-5)) and CPD (P=9.3 × 10(-5)). Notably, the variant most strongly associated with BMI (rs1558902-A in FTO) did not associate with smoking behavior. The association with smoking behavior is not due to the effect of the SNPs on BMI. Our results strongly point to a common biological basis of the regulation of our appetite for tobacco and food, and thus the vulnerability to nicotine addiction and obesity.

Insulin induces long-term depression of ventral tegmental area dopamine neurons via endocannabinoids.

The prevalence of obesity has markedly increased over the past few decades. Exploration of how hunger and satiety signals influence the reward system can help us understand non-homeostatic feeding. Insulin may act in the ventral tegmental area (VTA), a critical site for reward-seeking behavior, to suppress feeding. However, the neural mechanisms underlying insulin effects in the VTA remain unknown. We demonstrate that insulin, a circulating catabolic peptide that inhibits feeding, can induce long-term depression (LTD) of mouse excitatory synapses onto VTA dopamine neurons. This effect requires endocannabinoid-mediated presynaptic inhibition of glutamate release. Furthermore, after a sweetened high-fat meal, which elevates endogenous insulin, insulin-induced LTD is occluded. Finally, insulin in the VTA reduces food anticipatory behavior in mice and conditioned place preference for food in rats. Taken together, these results suggest that insulin in the VTA suppresses excitatory synaptic transmission and reduces anticipatory activity and preference for food-related cues.

Hypocretin/orexin in addiction: a mediator of stress-induced reinstatement of cocaine-seeking behaviour

The importance of the lateral hypothalamus in the pursuit of reward has long been recognized. However, the hypothalamic neuronal network involved in the regulation of reward still remains partially unknown. Hypocretins (aka orexins) are neuropeptides synthesized by a few thousand neurons restricted to the lateral hypothalamus and the perifornical area. Compelling evidence indicates that hypocretin neurons receive inputs from sensory and limbic systems and drive hyper-arousal possibly through modulation of stress responses. Major advances have been made in the elucidation of the hypocretin involvement in the regulation of arousal, stress, motivation, and reward seeking, without clearly defining the role of hypocretins in addictionrelated behaviors. We have recently gathered substantial evidence that points to a previously unidentified role for hypocretin-1 in driving relapse for cocaine seeking through activation of brain stress pathways. Meanwhile, several authors published concordant observations rather suggesting a direct activation of the mesolimbic dopamine system. In particular, hypocretin-1 has been shown to be critically involved in cocaine sensitization through the recruitment of NMDA receptors in the ventral tegmental area. Overall, on can conclude from recent findings that activation of hypocretin/orexin neurons plays a critical role in the development of the addiction process, either by contributing to brain sensitization (which is thought to lead to the unmanageable desire for drug intake) or by modulating the brain reward system that, in coordination with brain stress systems, leads to a vulnerable state that may facilitate relapse for drug seeking behavior.

Transfer pricing as a means for motivating management of profit centers

The main objective of this study is to analyze the role and potential of transfer pricing as a means of management control in large organizations. The special emphasis is on analyzing the potential of transfer pricing when we are motivating the profit center managers. The research approach is theoretical and literature reviews include studies about profit center organizations, performance measurement and analysis, incentive systems, transfer pricing techniques and agency theory. Based on the analysis, it seems that transfer pricing is a suitable tool for controlling, motivating and managing profit center managers. This requires that the performance measurement can be done fairly and transfer prices are set using fair assumptions. The motivating effects of transfer pricing can be enhanced if the reward system is connected to performance measurement system. In synthesis there is presented effects of transfer pricing to profit center managers behavior. There is also presented opinion about fair transfer pricing policy.

The 16p11.2 rearrangments genetic paradigms for obesity and neurodevelopmental disorders.

Recent discoveries of recurrent and reciprocal Copy Number Variants (CNVs) using genome- wide studies have led to a new understanding of the etiology of neuropsychiatric disorders. CNVs represent loss (deletion) or gain (duplication) of genomic material. This thesis work is focused on CNVs at the 16p11.2 BP4-BP5 locus, which are among the most frequent etiologies of neurodevelopmental disorders and have been associated with Autism Spectrum Disorders (ASD), schizophrenia, cognitive impairment, alterations of brain size as well as obesity and underweight. Because deletion and duplication of the 16p11.2 locus occur frequently and recurrently (with the same breakpoints), CNVs at this locus represent a powerful paradigm to understand how a genomic region may modulate cognitive and behavioral traits as well as the relationship and shared mechanisms between distinct psychiatric diagnoses such as ASD and schizophrenia. The present dissertation includes three studies: 1) The first project aims at identifying structural brain-imaging endophenotypes in 16p11.2 CNVs carriers at risk for ASD and schizophrenia. The results show that gene dosage at the 16p11.2 locus modulates global brain volumes and neural circuitry, including the reward system, language and social cognition circuits. 2) The second investigates the neuropsychological profile in 16p11.2 deletion and duplication carriers. While deletion carriers show specific deficits in language and inhibition, the profile of duplication carriers is devoid of specific weaknesses and presents enhanced performance in a verbal memory task. 3) The third study on food-related behaviors in 16p11.2 deletion and duplication carriers shows that alterations of the reponse to satiety are present in CNV carriers before the onset of obesity, pointing toward a potential mechanism driving the Body Mass Index increase in deletion carriers. Dysfunctions in the reward system and dopaminergic circuitries could represent a common mechanism playing a role in the phenotype and could be investigated in future studies. Our data strongly suggest that complex cognitive traits correlate to gene dosage in humans. Larger studies including expression data would allow elucidating the contribution of specific genes to these different gene dosage effects. In conclusion, a systematic and careful investigation of cognitive, behavioral and intermediate phenotypes using a gene dosage paradigm has allowed us to advance our understanding of the 16p11.2 BP4-BP5 locus and its effects on neurodevelopment. -- La récente découverte de variations du nombre de copies (CNVs pour 'copy number variants') dans le génome humain a amélioré nos connaissances sur l'étiologie des troubles neuropsychiatriques. Un CNV représente une perte (délétion) ou un gain (duplication) de matériel génétique sur un segment chromosomique. Ce travail de thèse est focalisé sur les CNVs réciproques (délétion et duplication) dans la région 16p11.2 BP4-BP5. Ces CNVs sont une cause fréquente de troubles neurodéveloppementaux et ont été associés à des phénotypes « en miroir » tels que obésité/sous-poids ou macro/microcéphalie mais aussi aux troubles du spectre autistique (TSA), à la schizophrénie et au retard de développement/déficience intellectuelle. La fréquence et la récurrence de la délétion et de la duplication aux mêmes points de cassure font de ces CNVs un paradigme unique pour étudier la relation entre dosage génique et les traits cognitifs et comportementaux, ainsi que les mécanismes partagés par des troubles psychiatriques apparemment distincts tels que les TSA et la schizophrénie. Ce travail de thèse comporte trois études distinctes : 1) l'étude en neuroimagerie structurelle identifie les endophénotypes chez les porteurs de la délétion ou de la duplication. Les résultats montrent une influence du dosage génique sur le volume cérébral total et certaines structures dans les systèmes de récompense, du langage et de la cognition sociale. 2) L'étude des profils neuropsychologiques chez les porteurs de la délétion ou de la duplication montre que la délétion est associée à des troubles spécifiques du langage et de l'inhibition alors que les porteurs de la duplication ne montrent pas de faiblesse spécifique mais des performances mnésiques verbales supérieures à leur niveau cognitif global. 3) L'étude sur les comportements alimentaires met en évidence une altération de la réponse à la satiété qui est présente avant l'apparition de l'obésité. Un dysfonctionnement dans le système de récompense et les circuits dopaminergiques pourrait représenter un mécanisme commun aux différents phénotypes observés chez ces individus porteurs de CNVs au locus 16p11.2. En conclusion, l'utilisation du dosage génique comme outil d'investigation des phénotypes cliniques et endophénotypes nous a permis de mieux comprendre le rôle de la région 16p11.2 BP4-BP5 dans le neurodéveloppement.

Osakeperusteinen palkitseminen: maksuttoman osakkeen hyödyntäminen kannustinjärjestelmissä

Tutkielman tavoitteena on selvittää osakeyhtiön palkitsemisjärjestelmiin liittyviä kysymyksiä päämies–agenttisuhteiden ja osakeyhtiöoikeudellisten periaatteiden kautta. Tutkielmassa selvitetään, kuinka maksuttomia osakkeita voidaan hyödyntää julkisen osakeyhtiön palkitsemisjärjestelmissä ja mitä haasteita ja mahdollisuuksia niiden käyttöön liittyy. Tutkimusmetodi työssä on lainopillinen ja aihetta lähestytään luontevasti kauppatieteellisen ja oikeustieteellisen näkökulman yhdistävän oikeustaloustieteen kautta. Ensisijaisena aineistona tutkielmassa käytetään voimassaolevaa lainsäädäntöä valmisteluaineistoineen ja näkökulmaa syvennetään aiemmin voimassa olleen lainsäädännön tarkastelulla. Toissijaisena aineistona tutkielmassa käytetään sekä eri asiantuntijoiden oikeudellista kirjallisuutta että palkitsemisen asiantuntijoiden laatimaa kirjallisuutta Suomesta ja muista länsimaista. Teoreettista työtä on syvennetty asiantuntijahaastattelulla ja yhtiöiden sijoittajatiedosta saatavalla informaatiolla. Merkittävin osakeyhtiön johdon ja yhtiön välisen suhteen tehokkuutta alentava seikka on päämies–agenttisuhteen valvontaongelma. Tämä liittyy päämies - agenttisuhteeseen, joka ilmenee negatiivisesti yhtiön ja yhtiön johdon intressien ristiriitatilanteissa. Valvontaongelma voi aiheuttaa ylimääräisiä transaktiokustannuksia ja tämä näkyy yhtiön toiminnan tehokkuuden laskemisena. Päämies–agenttisuhteen ratkaisuna lainsäädäntö ja erilaiset valvonnan keinot ovat tehottomia ja nykyisen yhtiöoikeudellisen ajattelun vastaisia. Tehokkaimmin valvontaongelma saadaan ratkaistua erilaisin kannustimin tapahtuvalla johdon ohjauksella. Osakesidonnainen palkitseminen on suosituin johdon ja yhtiön intressien yhdistämisen keino. Osakesidonnainen palkitseminen on parhaimmillaan eri osapuolien näkökulmasta sitouttavaa ja kannustavaa mutta osakepalkitsemisen käyttöön liittyy myös riskejä. Eräs keskeisistä yhtiöoikeudellisista periaatteista on yhdenvertaisuus, jota saatetaan loukata eri palkitsemisjärjestelmiä käytettäessä. Varojen jakoon ja järjestelmien rahoitukseen liittyy niin ikään riskejä, jotka saattavat vaarantaa järjestelmän onnistumisen. Liian avokätiset palkkiojärjestelmät taas saattavat aiheuttaa yhtiön eri sidosryhmien piirissä tyytymättömyyttä joka taas alentaa järjestelmän tehokkuutta. Yhtiön johto vastaa yhtiön strategian toteutumisesta ja linjaa Corporate Governance käytännön mukaisesti johdon palkitsemisen tavat. Yhtiön johto on kuitenkin päätöksistään vastuussa yhtiön residuaalioikeuden omaaville päämiehille, eli osakkeenomistajille. Vaikka yhtiön johto vastaa viime kädessä yhtiön toiminnasta, sen on huomioitava toiminnassaan yhtiön toiminnan tarkoitus ja sitä kautta yksittäisen osakkeenomistajan etu. Vaikka osakeyhtiössä toteutettaisiin enemmistöomistajan valitsemaa toimintalinjaa, osakeyhtiön yhdenvertaisuusperiaate korostaa juuri vähemmistöosakkeenomistajan asemaa. Johdon fidusiaaristen velvoitteiden voidaankin nähdä korostuvan johdon suhteessa vähemmistöosakkeenomistajaan. Tämä on huomioitava myös palkitsemisjärjestelmissä. Johdon palkitsemisjärjestelmien suunnittelussa ja toteutuksessa on suunnattava keskeinen huomio sen tavoitteiden toteutumiseen, eli yksittäisen osakkeenomistajan omistuksen arvon kasvattamiseen pidemmällä aikavälillä, pitäen huolta osakeyhtiön kantavista periaatteista.

Customer consciousness in the production process of a steel factory

The purpose of this thesis is to examine the level of customer consciousness of the production process employees in a steel factory and to investigate the methods of internal marketing in order to propose development practices to enhance the customer consciousness of the case company employees. The significance of the level of customer consciousness is discussed and practices already implemented affecting the level of customer consciousness in the company are examined. The literature review gives an insight to the role of customer consciousness in the CRM philosophy of a manufacturing company and examines the means of internal marketing in enhancing customer consciousness. In the empirical part of the study, the level and significance of customer consciousness is determined by conducting individual and focus group interviews. The interviews are also used to examine the practices that could function in enhancing the customer consciousness of the employees. Development suggestions to improve the level of customer consciousness in the production process are given based on the results. The level of customer consciousness is at a poor level in the production process and influences above all on work motivation and job satisfaction, but possibly on customer satisfaction as well. The enhancement of customer consciousness in the production process should be done e.g. by ensuring the distribution of right knowledge coherently to all of the employees, gathering large customer reference database to exploit in work and in training, using visual illustration in presenting the customer information, training proactively and letting the employees to participate in the customer oriented development activities. Customer satisfaction focused reward system can be considered.

Kehitysehdotus kattaa edellisiä ongelmakohtia korjaavia toimenpiteitä, jolloin kohdeyrityksen palkitsemisesta on saatavissa toiminnan ohella kehittyvä, kannustava ja toimintaa ohjaava kokonaisuus.

Rewards for Motivating Employees

When considering ways to motivate employees, one must keep in mind that each individual is different and therefore everyone is motivated in different way. Employees can have quite different motivators, for example, more money, more recognition, flexible working hours, promotions, opportunities for learning, or discounts for employee and his/her family. Therefore, when attempting to help motivate people, it is important to discover what the individual motivation factors are for each one personally. Another key factor is the variation over time. Nobody experiences a constant set of needs over time, it will change slowly. One of the most fundamental concerns of reward management is how it can help to motivate people so that they achieve their full potential. The development of a performance culture is a typical aim of reward strategy. It is therefore necessary to understand the factors that motivate people and how, in the light of these factors, rewarding process and practices that will enhance motivation, commitment, job engagement and positive discretionary behavior, can be developed. The purpose of this research is to examine more in detail of the total reward systems which are used in two public sectors and their cultural differences and/or similarities. The study is focused on two different public sectors; Vantaa City Authority (Finland) and Hertfordshire County Authority (the United Kingdom). The research questions are: How do public sector employers attempt to reward their employees with a total reward system? • What are the different ways to motivate employees? • What is the reward system in the public sector based on? • What characteristics are included in the total reward system? • How does the culture affect the ways of motivation and rewarding? The benefits of a total reward approach are, for example, the greater impact which means that the combined effect of the different types of rewards will make a deeper and longer-lasting impact on the motivation and commitment of people. It also enhances the employment relationship, meaning that the employment relationship created by a total rewards approach makes the maximum use of relational as well as transactional rewards and will therefore appeal more to individuals. The research findings point out that in Finland rewards are based on just for the employees, recognition of individuals is high, in several cases they reward teams, and organisation climate is important issue for them. In the United Kingdom, the reward system is based on rewarding employees and their families, employer offer several discounts for employees and families, and flexible working hours are favourable.

Intra-organizational knowledge transfer in a Finnish multinational company

The ability of a multinational company to effectively transfer knowledge from one unit to another can create a great source of competitive advantage and is crucial for long-term success. However, in their attempts to disseminate existent knowledge across national boundaries, organizations encounter several obstacles. Especially challenging is the transfer of tacit knowledge, the most valuable kind, as it is embedded in the minds and the behavior of people. The purpose of this study is to identify the main factors and challenges to be considered in intra-organizational knowledge transfer and consequently develop a framework that could be utilized to improve the process. The research is of qualitative nature and it adopts an exploratory approach. The study was further conducted as an intensive single-case study through studying a Finnish multinational company, and the researcher adopted a role as a participant observant in the research setting. Other data collection methods include semi-structured interviews and an online survey. The research findings show that knowledge transfer is currently challenging within the international sales organization of the case company. The majority of knowledge is currently concentrated in the company headquarters, and it is not always systematically distributed to the regional offices abroad. The main factor affecting knowledge transfer seems to be the organizational culture, which does not support or encourage knowledge sharing. The company is struggling in having a common place for information and employees that lack proper social networks have difficulties accessing relevant knowledge. Some recommended improvement suggestions include the institutionalization of knowledge transfer by turning it into an articulated organizational goal, and the implementation of a reward system that includes soft factors, such as teamwork and knowledge sharing behavior. Furthermore, the organizational culture should be more open and supportive in order to reinforce trust. Individuals in regional offices should be given better support by offering them dedicated mentors and increasing the amount of expatriation. Finally, knowledge should actively be codified and stored in commonly shared platforms where it is easily accessible by all employees.
