Full textTiivistelmä Innovaatiot syntyvät yritysten, yliopistojen, tutkimuslaitosten ja julkisten toimijoiden verkostoissa. Innovaatiot ovat yritysten, yhteisöjen ja kansojen menestyksen lähde, joten niiden tutkimuksella on pitkät perinteet. Verkostomaisella tuotekehitystoiminnalla uusien innovaatioiden: tuotteiden ja palveluiden kehittäjät vastaavat markkinoiden globalisaation, tutkimuksen erikoistumisen ja tiedon fragmentoitumisen aiheuttamaan tiedollisten ja taloudellisten resurssien vaatimusten kasvuun. Yhteistyö tutkimus- ja kehitysverkostoissa (T&K) on välttämätöntä, koska tarvittavat resurssit, osaaminen ja kyvykkyydet eivät ole yksittäisten toimijoiden hallussa tai hallittavissa. T&K-verkot voivat olla toimijoiden tarkoituksellisesti kokoamia, muodistua vapaasti toimijoiden havaitessa yhteiset intressit tai muodostua aikaisemmista verkostossa toimineiden toimijoiden sulautuessa tutkimaan ja kehittämään yhdessä. Tämä tutkimus keskittyy tarkoituksellisesti koottujen T&K-verkkojen tutkimus- ja kehitysverkkojen johtamiseen. Tämän tutkimuksen tavoitteena on kuvata, ymmärtää ja käsitteellistää: ensiksi, miten tutkimus- ja kehitysverkoissa johdetaan verkon muodostumisen ja varsinaisen tutkimus- ja kehitystoiminnan aikana, toiseksi mitä etuja tutkimus- ja kehitysverkon johtamisella on verkon toimijoille ja kolmanneksi, mitä haasteita tutkimus- ja kehitysverkon johtamisessa on ja kolmanneksi, T&K-verkkojen johtaminen kattaa tässä tutkimuksessa johtamisen prosessit ja johtamisen rooli. T&K-verkkojen johtamista tutkitaan kahdessa vaiheessa, ensiksi empiirisesti neljän (4) vertaisarvioidun tutkimuspaperin avulla. Tutkimuspaperit perustuvat yhden tapauksen pitkittäistutkimukseen T&K-verkoissa johtamisesta. Tapaustutkimuksessa tarkastellaan tapausta seuranta- ja historiatutkimuksen aikaperspektiivistä. Toiseksi, koska tutkimuspaperien julkaiseminen on ajoittunut vuosille 2005-2008, tulee niiden tuloksista johdettava kontribuutio verrata uudemman aikalaiskirjallisuuden kanssa. Tästä johtuen tutkimuksen toisessa vaiheessa on toteutettu järjestelmällinen kirjallisuuskatsaus vuosien 2004–2014 verkostojen johtamisen kirjallisuudesta. Sen jälkeen ja systemaattisen kirjallisuuskatsauksen vertailuun perustuen, keskustellaan tämän tutkimuksen tuloksista, jotka tukevat, kiistävät ja/tai esittävät yhä uusia tutkimustuloksia. Uusina tuloksia tämä tutkimus esittää T&K-verkkojen muodostumisen ja tuotekehitysyhteistyön johtamisen prosessin tarkastelujakson muutoksia. Toiseksi tutkimus esittää mallin T&K-verkkojen muodostumisen ja tuotekehitysyhteistyön aikaisen johtamisen mallin. Kolmanneksi tutkimus esittää T&K-verkkojen johtamisen roolien tyypittely ja analysointimallin. Lopuksi tutkimus esittää tutkimuksessa havaittuja T&K-verkkojen johtamisen etuja ja haittoja. Tämä tutkimus antaa suosituksia liikkeenjohtajille sekä tulevalle T&K-verkoissa tapahtuvan johtamisen tutkimukselle

Full textBackground and problem: The focus lies on the decision and judgment of how to account for R & D in the entities, if it is an intangible asset or not. Aim: The aim with the study is to increase the knowledge of how entities account for R&D. One part of the aim is to also explain why they are doing it in that way. Another aim of the study is to explore if the accounting of the R&D is influenced by subjectivity. Method: A qualitative research method where case studies as the main design has been used. The empirical material has been collected through four interviews. Three of these interviews were made with persons in for the study interesting companies which had the possibility to capitalize development cost in the balance sheet. To have another picture and perspective on the situation one interview was made with an authorized public accountant. Result and conclusion: The foremost reason to how the entities in the study account for R&D is what the standard, IFRS, tells. It is possible to convince with argument to do company specific interpretations and applications of the principles in IFRS. For example this could be done thrue application of the principle of carefulness or of the principle of essential in the judgment and decision if the R&D fulfills the criteria for capitalizing, especially IAS 38, point 57 d. Some entities who account according to IFRS use company specific criterion of essential for materiality which state a lowest amount for development cost to be activated. These lower boundaries for materiality leave a relative big space to the entities not to activate development cost in the balance sheet if that is what the company wish. None of the interviewed persons in the study think that scarce communication between economist and engineers affect the judgment and decision of R&D and if the development cost is an intangible asset.

Full textBackground and problem: We have identified a room for discretion and interpretation in IAS 38 regarding the criteria for capitalization of R&D expenses. This can be a problem if there is a risk for variation in interpretation and use of the criteria, which can in turn affect the comparability between companies in the accounting for R&D. Aim: The aim with this study is to analyze the comparability between companies in the accounting for R&D from an information asymmetry perspective. We intend to illustrate the use of the criteria in IAS 38 regarding variation between companies. Our purpose is to use the prudence and matching principle to explain a possible variation. Method: The choice of method is a qualitative research through deep interviews with five companies in the IT-industry. During the interviews we have treated the decision-making process for capitalization of R&D and the companies’ attitude to the trade off between prudence and matching principle. In the study we have used an analysis model that illustrate the conflict between the prudence and matching principle as a scale. The companies’ placement on the scale regarding their accounting for R&D makes the foundation for our analysis. Result and conclusion: From our empirical results we have found that the companies’ unique conditions, like the structure of R&D-projects, knowledge of the product demand and project accounting system affect the usage of the criteria in IAS 38. The different conditions in all the companies have resulted in different policy decisions regarding capitalization. Therefore the policy decision affects the usage of the criteria. We have only seen weak trends that the prudence and matching principle can explain the policy decision in the companies. Therefore we cannot for certainty conclude that accounting principles affect the usage of the criteria in IAS 38. The results indicate that the accounting for R&D is not comparable because of the variation in policy decision.

Full textAim: Developing an strong brand is a way for companies to stand out of the crowd, which today is necessary to conquer on the competitive market. The brand value is one of the most important assets in annual reports, but there are difficult to estimate an reliable value. It depends on the fact that the brand value is affected by few different factors, including innovativ-eness. Due to the thesis background the purpose enunciate: The purpose of this thesis is to investigate it there is a correlation between companies brand value and innovation capacity. Method: We have done a secondary data analysis, with help from the database Retriever. The combination of faint information and lack of quality in Retrievers capacity it contributed that we had to use semi-structured interviews as an complement to full follow the purpose. The paper per- form at Stockholm Nasdaq OMX and included de 250 largest companies that at least had one registered brand value. Companies with inapplicable data for the purpose of the study was elimi- nated. As a final the data was analysed by dint of linear regression, Pearsons correlation analysis, and interviews thru ”well-grounded theory”. Result & Conclusion: The result of the study indicated that there are positive relation between brand value and R&D. The complemented interviews contributed that the authors observed diff- erences between practitioners and researchers on the perception of between essential accounting information and the opportunities to provide principles to circumvent the recommendations. The conclusion of the study is that companies brand value are positively affected by the innovativeness. Suggestions for future research: Due to the lack of resources and qualitative database it wasn’t possible to satisfy the purpose of the study. Consequently our suggestion for future research will contain the recommendation to do the study on another stock exchange. Contribute of the thesis: Mainly this study contributes to illuminate the fact of accounting information: companies doesn't inform sufficient information to increase knowledge for there own business innovativeness and immaterial assets. Which can be seen as a problem. Second contribute comprises that there is, hence small or implicit, relation between brand value and their companies innovativeness at the researched companies. Consequently the results gets difficult to draw general conclusion from.

Full textDermatitis herpetiformis (DH) is an inflammatory skin disease characterized by granular IgA deposits in the papillary dermis and represents an extra-intestinal manifestation of coeliac disease (CD). DH and CD are autoimmune diseases, both share a similar genetic HLA background, have serum IgA antibodies and benefit clinical improvement with a gluten free dietary treatment. The epidermal transglutaminase (TG-3) has been recognised as the main autoantigen in DH disease. In this study the presence and the production of TG-3 protein at intestinal and peripheral level are demonstrated. This evidence induced us to investigate the origin’s site of TG-3 antibodies in both areas. To carry out a project, the antibody-Libraries display technologies are used. Antibody-Libraries from intestinal and peripheral B lymphocytes of three DH and three control patients were constructed and examined by using the phage and yeast-display antibody methods. The combination of these technologies allowed to isolate and characterize anti-TG-3 antibodies, suggesting that both, intestinal and peripheral level, could be the primary site of antibodies production. The present study also focused on investigating the pathogenetic role of anti-TG-3 antibodies in DH disease. Human keratinocytes, representing the inflammatory site of DH, are proposed as a suitable in vitro model. The TG-3 protein is detected in the intracellular compartment but not in the plasma membrane, suggesting that the antigen-antibody binding site does not occur on keratinocytes. Therefore, this in-vitro model does not allow to investigate the pathogenetic role of anti-tg3 antibodies.

Full texthowever, the control of the cell organization and cell behavior to create fully functional 3-D constructs has not yet been achieved. To overcome these, activities have been concentrated on the development of multi-functional tissue engineering scaffolds capable of delivering the required bioactive agents to initiate and control cellular activities. The aim of this study was to prepare tissue engineered constructs composed of polymeric scaffolds seeded with mesenchymal stem cells (MSCs) carrying a nanoparticulate growth factor delivery system that would sequentially deliver the growth factors in order to mimic the natural bone healing process. To achieve this, BMP-2 and BMP-7, the osteogenic growth factors, were encapsulated in different polymeric nanocapsules (poly(lactic acid-co-glycolic acid) (PLGA) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV)) with different properties (degradation rates, crystallinity) and, therefore, different release rates to achieve the early release of BMP-2 followed by the release of BMP-7, as it is in nature. Initially, these nanoparticulate delivery systems were characterized and then the effect of single, simultaneous and sequential delivery of BMP-2 and BMP-7 from these delivery systems was studied in vitro using rat bone marrow MSCs. The effect of using these two growth factors in a sequential manner by mimicking their natural bioavailability timing was shown with maximized osteogenic activity results. BMP-2 loaded PLGA nanocapsules were subcutaneously implanted into Wistar rats and according to initial results, their biocompatibility as well as the positive effect of BMP-2 release on the formation of osteoclast-like cells was shown. To complete the construction of the bioactive scaffold, this nanoparticulate sequential delivery system was incorporated into two different types of polymeric systems
natural (chitosan) and synthetic (poly(&

-caprolactone) (PCL)). 3-D fibrous scaffolds were produced using these materials by wet spinning and 3-D plotting. Incorporation of nanocapsules into 3-D chitosan scaffolds was studied by two different methods: incorporation within and onto chitosan fibers. Incorporation into 3-D PCL scaffolds was achieved by coating the nanocapsules onto the fibers of the scaffolds in an alginate layer. With both scaffold systems, incorporation of nanocapsule populations capable of delivering BMP-2 and BMP-7 in single, simultaneous and sequential fashion was achieved. As with free nanocapsules, the positive effect of sequential delivery on the osteogenic differentiation of MSCs was shown with both scaffold systems, creating multi-functional scaffolds capable of inducing bone healing.

Full textIntroduction: Vitamin D and its effects on human health are topics that are attracting great interest, and in recent years there is a rapid increase in the number of publications about vitamin D and its relationship to asthma, allergies and respiratory infections. This discovery, together with the realization that essentially every tissue and cell in the body has vitamin D receptors, has prompted new interests in the vitamin D system and its previously unrecognized actions. Recent data suggest that hypovitaminosis D is associated with many nonskeletal conditions such as asthma. Objectives: We investigated the relationship between vitamin D serum levels, lung function and asthma control in children and smoking habits of their parents. Materials and Methods: We estimated the correlation between the concentration of 25-hydroxycholecalciferol [25(OH)D], lung function parameters obtained from baseline spirometry and levels of asthma control, according to the guidelines Global Initiative for Asthma (GINA) and the Childhood Asthma Control Test (C- ACT), in 152 children with asthma (aged 5-15 years, 84 males) in a cross-sectional study conducted during the winter and spring. We have also studied the existence of a possible association between the smoking habits of parents and the vitamin D levels of these children with asthma. Results: Only 9.9 % of our children had sufficient vitamin D serum levels (between 30 and 40 ng / ml). We found a moderate positive correlation between the forced vital capacity percent predicted and the vitamin levels ( Spearman ρ = 0.36 , 95% CI = 0.22 to 0.50, P <0.001). This finding was also found for the forced expiratory volume in 1 second ( ρ = 0.36 , 95% CI = 0.23 to 0.50, P <0.001). Patients with well-controlled asthma showed serum levels of vitamin D higher than children with not or partly controlled asthma, with median values equal to 22.4 ng/ml (IQR = 18.2 - 26.0 ng / ml), 17.8 ng/ml (IQR = 12.6 - 22.0 ng/ml) and 13.5 ng/ml (IQR = 10.1 - 18.1 ng / ml), respectively (P <0.001) . We have also identified a moderately positive correlation between 25(OH)D levels of and the C -ACT score (r = 0:49, 95% CI = 0.36-0.62 , P <0.001). By analyzing the smoking habits of parents in relation to vitamin D serum levels, a statistically significant association between the two parameters was present. In particular, serum levels appear to be significantly reduced if both parents report smoking regularly (P <0.001). Conclusions: Our results suggest that hypovitaminosis D is frequent in children with asthma living in a Mediterranean country. In these children, lower vitamin D serum levels are associated with reduced asthma control and lung function. The study also suggests that passive smoking could be a causal factor for hypovitaminosis D in children with asthma. However, further studies to verify this relationship, in particular by analyzing biomarkers of exposure to cigarette smoke are necessary.

Full textAtopic dermatitis is a chronic relapsing inflammatory skin disease with multifactorial etiology with a structural damage to the barrier of the skin. Recent studies have revealed a possible role of vitamin D. Indeed, vitamin D reduced the expression of CLA on the T cells, regulating the recruitment skin, increased the e3xpression of keratinocyte catelicidina at enhancing the antimicrobial defenses of the skin. Serious atopic dermatitis are often associated with the presence of IgE anti-staphylococcal toxins . The aim of our study is therefore to assess whether the severity of the disease quantified with SCORAD scores correlated with serum levels of vitamin D and with the presence of IgE anti staphylococcal toxins and M. Furfur and if the damage to barriers and awareness staphylococcal eneterotoxins depend on vitamin D itself. Materials and method: the severity of dermatitis was quantified by the SCORAD score that classifies the dermatitis in mild, moderate, serious using objective parameters as extent and intensity and subjective parameters as itching and sleep loss. To measure the trans epidermal water loss (TEWLS) we used tewameter. The IgE to staphylococcal enterotoxins A,B,C and to Malassetia furfur occurred on peripheral blood. The dose of vitamin D was considered sufficient to level >30 ng/L, insufficient >30 ng/L, lacking <20 ng/L. Results: the significativity of the date and the comparisons between the various groups studied was made by the statistical method of linear regression analysis. The correlation between the dose of vitamin D and the SCORAD was significant (p=0.016, r=0.38). Between vitamin D and TEWL is not statistically significant as well as between the does of vitamin D and IgE to enterotoxins A,B, C and M. furfur. The correlation between the sensitization and the SCORAD was not statistically significant as well as between vitamin D and sensitization. Conclusions: children with low serum levels of vitamin D have a SCORAD more high and therefore greater severity of disease. The study provides a good basis for further studies on the treatment of atopic dermatitis with supplementation of vitamin D.

Full textIntroduction. Hypovitaminosis D is an independent risk factor for cardiovascular morbidity. In adults, low levels of vitamin D are associated with hypertension, insulin resistance, cardiovascular disease, metabolic syndrome and diabetes. At present, no data are available about the relationship between cardiovascular and metabolic risk factors and hypovitaminosis D in children. Aim. The aim of this study was to evaluate the relationship between hypovitaminosis D and cardiovascular and metabolic risk factors such as hypertension evaluated with 24-h ABP patterns, hepatic steatosis, dyslipidemia and glucose intolerance in overweight and obese children and adolescent. Subjects and methods. Fifty-three Caucasian children (35 males and 18 females) aged 7-16 yrs were recruited among the overweight and obese children followed at the Department of Paediatrics of the Verona University Hospital, between October 2009 and July 2010. Exclusion criteria were chronic diseases, malformations, chronic use of drugs, including vitamin D or multivitamin supplements. We recorded anthropometric parameters, took blood samples for 25-hydroxivitamin D measurements, total LDL and HDL cholesterol, triacylglycerol, ALT and monitored ambulatory blood pressure (ABP). All children underwent OGTT and hepatic ultrasonography. Results. Hypovitaminosis D was diagnosed in 81% of the study group children (vitamin D deficiency (25(OH)D < 20 ng/ml) in 66% of children, vitamin D insufficiency (25(OH)D between 20 ng/ml and 30 ng/ml) in 15%). Vitamin D levels were negatively correlated with HOMAIR and fasting insulin, and positively with QUICKI. No relationship was found neither between fasting glucose, OGTT parameters and vitamin D levels, or between vitamin D total, LDL, HDL and cholesterol. We found nocturnal systolic pressure to be significantly higher in children with lower values of vitamin D. The 24-h diastolic BP load, the nighttime diastolic BP load and the nighttime systolic BP index increased progressively as the vitamin D deficiency worsened. We found a negative correlation between vitamin D levels and with 24-hour and nighttime systolic BP, 24-h diastolic BP load, nighttime systolic and diastolic BP load, 24-h systolic ABP index and nighttime systolic BP index. No relationship was found between daily diastolic hypertension level, daytime BP index or daytime BP load and vitamin D levels except for diastolic BP load. Conclusions. Our study is the first study that analyzed the relationship between vitamin D levels and 24-h BP patterns in obese children and adolescents; in agreement with previous studies it adds relevant information about the relationship between low vitamin D levels and high nocturnal blood pressure levels. Moreover we found a high prevalence of hypovitaminosis D in obese children and adolescent and a correlation between the severity of vitamin D deficiency and insulin resistance evaluated as HOMAIR. Prospective studies and vitamin D supplementation trials could confirm a cause-effect relationship between vitamin D and BP or insulin resistance also in children/adolescents.

Full textThe aims of this research are to analyse the level of mandatory and voluntary disclosure about R&D activities, analyse the impact that the international financial crisis had on this disclosure and analyse the determinants of the information about these activities, after the adoption of IAS 38. For the empirical study a sample of 88 Information and Communication Technology and Pharmaceutical Industry companies was selected, which were listed on the Stock Exchanges of six European Union countries with a high level of R&D activities (Sweden, Finland, Austria, Denmark, Germany and France), in the years 2005-2008 and 2012-2013. The results obtained show that the companies of the sample, in general, disclosed in the Annual Reports the information required by IAS 38. As regards the voluntary disclosure, the results show that the level of disclosure is relatively low. It was also found that the international financial crisis did not negatively affect the level of disclosure of mandatory and voluntary information about R&D activities. With regard to the determinant factors of disclosure of information under study, the explanatory variables of industry type, R&D partnerships and company age are statistically significant for the Mandatory Disclosure Index dependent variable, and the explanatory variables of leverage, industry type, R&D partnerships and company age are statistically significant for the Voluntary Disclosure Index dependent variable.
