In the context of the publication of DSM-5, the Personality Inventory for DSM-5 (PID-5) has been proposed as a new dimensional assessment tool for personality disorders. This instrument includes a pool of 220 items organized around 25 facets included in a five-factor second-order domain structure. The examination of the replicability of the trait structure across methods and populations is of primary importance. In view of this need, the main objective of the current study was to validate the French version of the PID-5 among French-speaking adults from a European community sample (N=2,532). In particular, the assumption of unidimensionality of the 25 facet and the five domain scales was tested, as well as the extent to which the five-factor structure of the PID-5 and the DSM-5 personality trait hierarchical structure are replicated in the current sample. The results support the assumption of unidimensionality of both the facets and the domains. Exploratory factor and hierarchical analyses replicated the five-factor structure as initially proposed in the PID-5.

This study main purpose was the validation of both French and German versions of a Perceived Neighborhood Social Cohesion Questionnaire. The sample group comprised 5065 Swiss men from the "Cohort Study on Substance Use Risk Factors." Multigroup Confirmatory factor analysis showed that a three-factor model fits the data well, which substantiates the generalizability of Perceived Neighborhood Social Cohesion Questionnaire factor structure, regardless of the language. The Perceived Neighborhood Social Cohesion Questionnaire demonstrated excellent homogeneity (α = 95) and split-half reliability (r = .96). The Perceived Neighborhood Social Cohesion Questionnaire was sensitive to community size and participants' financial situation, confirming that it also measures real social conditions. Finally, weak but frequent correlations between Perceived Neighborhood Social Cohesion Questionnaire and alcohol, cigarette, and cannabis dependence were measured.

Thermodynamic properties and radial distribution functions for liquid chloroform were calculated using the Monte Carlo method implemented with Metropolis algorithm in the NpT ensemble at 298 K and 1 atm. A five site model was developed to represent the chloroform molecules. A force field composed by Lennard-Jones and Coulomb potential functions was used to calculate the intermolecular energy. The partial charges needed to represent the Coulombic interactions were obtained from quantum chemical ab initio calculations. The Lennard-Jones parameters were adjusted to reproduce experimental values for density and enthalpy of vaporization for pure liquid. All thermodynamic results are in excelent agreement with experimental data. The correlation functions calculated are in good accordance with theoretical results avaliable in the literature. The free energy for solvating one chloroform molecule into its own liquid at 298 K and 1 atm was computed as an additional test of the potential model. The result obtained compares well with the experimental value. The medium effects on cis/trans convertion of a hypotetical solute in water TIP4P and chloroform solvents were also accomplished. The results obtained from this investigation are in agreement with estimates of the continuous theory of solvation.

This paper adopts dynamic factor models with macro-finance predictors to test the intertemporal risk-return relation for 13 European stock markets. We identify country specific, euro area, and global macro-finance factors to determine the conditional risk and return. Empirically, the risk- return trade-off is generally negative. However, a Markov switching model documents that there is time-variation in this trade-off that is linked to the state of the economy. Keywords: Risk-return trade-off; Dynamic factor model; Macro-finance predictors; European stock markets; Markov switching model JEL Classifications: C22; G11; G12; G17

Soil properties on the Cap de Creus Peninsula, NE Spain depend primarily on scarce agricultural practices and early abandonment. In the study area, 90% of which is mainly covered by Cistus shrubs, 8 environments representing variations in land use/land cover and soil properties at different depths were identified. In each environment variously vegetated areas were selected and sampled. The soils, collected at different depths, were classified as Lithic Xerorthents according to the United States Department of Agriculture system of soil classification (USDA-NRCS 1975). Differences in soil properties were largely found according to the evolution of the plant canopy and the land use history. To identify underlying patterns in soil properties related to environmental evolution, factor analysis was performed and factor scores were used to determine how the factor patterns varied between soil variables, soil depths and selected environments. The three-factor model always accounted for 80% of the total variation in the data at the different soil depths. Organic matter was the more relevant soil property at 0–2 cm depth, whereas active minerals (silt and clay) were found to be the most relevant soil parameters controlling soil dynamics at the other depths investigated. Results showed that vineyards and olive tree soils are poorly developed and present worse conditions for mineral and organic compounds. Analysis of factor scores allowed independent assessment of soils, depth and plant cover and demonstrated that soils present the best physico-chemical characteristics under Erica arborea and meadows. In contrast, soils under Cistus monspeliensis were less nutrient rich and less well structured

Music is one of the most pleasant human experiences, even though it has no direct biological advantage. However little is known about individual differences in how people experience reward in music-related activities. The goal of the present study was to describe the main facets of music experience that could explain the variance observed in how people experience reward associated with music. To this end we developed the Barcelona Music Reward Questionnaire (BMRQ), which was administrated to three large samples. Our results showed that the musical reward experience can be decomposed into five reliable factors: Musical Seeking, Emotion Evocation, Mood Regulation, Social Reward, and Sensory-Motor. These factors were correlated with socio-demographic factors and measures of general sensitivity to reward and hedonic experience. We propose that the five-factor structure of musical reward experience might be very relevant in the study of psychological and neural bases of emotion and pleasure associated to music.

Työssä tutkitaan erään tekniseen auringonsuojaukseen keskittyneen yrityksen päätöstä tuottaa aloittelevia yrityksiä palveleva tukikonsepti. Konsepti sisältää mitoitusohjelmia, kokoonpano-ohjeita sekä markkinointimateriaalia. Oleellista on selvittää kannattaako yrityksen keskittyä kyseisiin asiakkaisiin, sekä onko konsepti oikea ratkaisu tälle segmentille. Tätä varten työssä tutustuttiin toimiala-analyysiin, strategiaan, segmentointiin sekä differointiin. Työssä selvitettiin, että Porterin viiden voiman malli on yhä toimiva aloitus toimiala-analyysin laatimiseen. Strategiaan liittyviä koulukuntia löytyy kirjallisuudesta useita erilaisia, oleellista on löytää oikea lähestymistapa kuhunkin tilanteeseen. Segmentointi on tärkeä vaihe, koska sen avulla selvitetään yrityksen eri asiakasryhmiä. Differointi on usein suositeltu keino kilpailuedun tavoittelemiseen. Työtä varten laadittiin yritykselle toimiala-analyysi. Lisäksi yritykselle etsittiin segmenttejä sekä pohdittiin sen mahdollisuuksia differointiin. Segmenttejä löydettiin kolme erilaista. Samalla todettiin, että paras tapa differoida yrityksen tuotteita on keskittyä tuotteiden aineettomiin ominaisuuksiin. Toimiala-analyysin, segmenttien sekä differointimahdollisuuksien perusteella päädyttiin siihen, että yrityksen päätös keskittyä enemmän uusiin ja aloitteleviin asiakkaisiin vaikuttaa järkevältä. Konseptin ominaisuuksien perusteella myös konsepti vaikuttaa hyvältä tavalta palvella kyseistä asiakassegmenttiä.

Tämän tutkimuksen tarkoituksena on selvittää mitkä tekijät ovat mikroyrityksen kasvun edellytyksenä ja mitkä tekijät ovat kasvun esteinä. Tutkimuksen taustalla on mikroyritysten yleisesti vähäinen kasvuhalukkuus. Tässä tutkimuksessa yrittäjien kasvuaikomuksia tarkastellaan kasvun prosessimalliin tukeutuen ja mikroyritysten kasvuun vaikuttavia tekijöitä tarkastellaan Perrenin mikroyrityksen kasvuun vaikuttavien tekijöiden mallin avulla. Tutkimuksessa on käytetty kvalitatiivista tutkimusmenetelmää. Tutkimus on toteutettu haastattelututkimuksena, jossa on haastateltu mikroyrittäjiä Päijät-Hämeessä Lahden ja Hollolan alueilla. Tämän tutkimuksen mukaan mikroyritysten kasvuun vaikuttavat yrittäjän tahtotila ja kyky yrityksen kehittämiseen sekä yrittäjän riskinottokyky että suotuisat ympäristölliset olosuhteet. Näiden tekijöiden puuttuminen estää kasvun. Yrityksen kasvua estäviä muita tekijöitä ovat tutkimuksen mukaan mikroyritysten liiallinen paikallisuus, yhteistyön vähäisyys sekä yrittäjän liiallinen kietoutuminen liiketoimintaan että toiminnan liian vähäinen strateginen suunnittelu.

Female sexual dysfunctions, including desire, arousal, orgasm and pain problems, have been shown to be highly prevalent among women around the world. The etiology of these dysfunctions is unclear but associations with health, age, psychological problems, and relationship factors have been identified. Genetic effects explain individual variation in orgasm function to some extent but until now quantitative behavior genetic analyses have not been applied to other sexual functions. In addition, behavior genetics can be applied to exploring the cause of any observed comorbidity between the dysfunctions. Discovering more about the etiology of the dysfunctions may further improve the classification systems which are currently under intense debate. The aims of the present thesis were to evaluate the psychometric properties of a Finnish-language version of a commonly used questionnaire for measuring female sexual function, the Female Sexual Function Index (FSFI), in order to investigate prevalence, comorbidity, and classification, and to explore the balance of genetic and environmental factors in the etiology as well as the associations of a number of biopsychosocial factors with female sexual functions. Female sexual functions were studied through survey methods in a population based sample of Finnish twins and their female siblings. There were two waves of data collection. The first data collection targeted 5,000 female twins aged 33–43 years and the second 7,680 female twins aged 18–33 and their over 18–year-old female siblings (n = 3,983). There was no overlap between the data collections. The combined overall response rate for both data collections was 53% (n = 8,868), with a better response rate in the second (57%) compared to the first (45%). In order to measure female sexual function, the FSFI was used. It includes 19 items which measure female sexual function during the previous four weeks in six subdomains; desire, subjective arousal, lubrication, orgasm, sexual satisfaction, and pain. In line with earlier research in clinical populations, a six factor solution of the Finnish-language version of the FSFI received supported. The internal consistencies of the scales were good to excellent. Some questions about how to avoid overestimating the prevalence of extreme dysfunctions due to women being allocated the score of zero if they had had no sexual activity during the preceding four weeks were raised. The prevalence of female sexual dysfunctions per se ranged from 11% for lubrication dysfunction to 55% for desire dysfunction. The prevalence rates for sexual dysfunction with concomitant sexual distress, in other words, sexual disorders were notably lower ranging from 7% for lubrication disorder to 23% for desire disorder. The comorbidity between the dysfunctions was substantial most notably between arousal and lubrication dysfunction even if these two dysfunctions showed distinct patterns of associations with the other dysfunctions. Genetic influences on individual variation in the six subdomains of FSFI were modest but significant ranging from 3–11% for additive genetic effects and 5–18% for nonadditive genetic effects. The rest of the variation in sexual functions was explained by nonshared environmental influences. A correlated factor model, including additive and nonadditive genetic effects and nonshared environmental effects had the best fit. All in all, every correlation between the genetic factors was significant except between lubrication and pain. All correlations between the nonshared environment factors were significant showing that there is a substantial overlap in genetic and nonshared environmental influences between the dysfunctions. In general, psychological problems, poor satisfaction with the relationship, sexual distress, and poor partner compatibility were associated with more sexual dysfunctions. Age was confounded with relationship length but had over and above relationship length a negative effect on desire and sexual satisfaction and a positive effect on orgasm and pain functions. Alcohol consumption in general was associated with better desire, arousal, lubrication, and orgasm function. Women pregnant with their first child had fewer pain problems than nulliparous nonpregnant women. Multiparous pregnant women had more orgasm problems compared to multiparous nonpregnant women. Having children was associated with less orgasm and pain problems. The conclusions were that desire, subjective arousal, lubrication, orgasm, sexual satisfaction, and pain are separate entities that have distinct associations with a number of different biopsychosocial factors. However, there is also considerable comorbidity between the dysfunctions which are explained by overlap in additive genetic, nonadditive genetic and nonshared environmental influences. Sexual dysfunctions are highly prevalent and are not always associated with sexual distress and this relationship might be moderated by a good relationship and compatibility with partner. Regarding classification, the results supports separate diagnoses for subjective arousal and genital arousal as well as the inclusion of pain under sexual dysfunctions.

The construction material sector, as a capital intensive industry, is highly vulnerable to rapid fluctuations in the economic cycles. In Finland this was witnessed especially during the late 2000s, as in 2007 and 2008 the demand for several construction materials exceeded their supply and right after this, in 2009 the demand collapsed fast as a result of an international recession. These factors brought about the need to study the future trends of the market place of the commissioning company, Finnsementti Oy. As reliable short term market forecasts for the sector are difficult to compose, the study concentrates primarily in examining and identifying the trends that are likely to affect the Finnish cement industry, and as an extension, the concrete industry in a frame of 10 to 15 years. The study’s scope comprehends also the examination of the domestic construction sector, as it represents the end user industry of both cement and concrete. These motives for the study produce the research problem, which is to conduct a trend analysis for cement based building in the Finnish market area in the 2020s. The theoretical frame for composing a trend analysis in the case of this study is twofold. This is due to the fact that both, the macro and micro environments of the examined industries are studied. The main methods used are the PESTE-model (macro) and Porter’s five forces model (micro). The study applies a qualitative approach and the data is gathered by interviewing a group of experts from the cement, concrete and construction industries. The result of the paper is an overall trend analysis for the Finnish cement based building sector, which is based on ‘sub trend analyses’ concerning four identified sub-sectors of the Finnish construction industry. The results are a combination of findings from these sub-sectors and the analyzed data that deals with the studied sector’s macro and micro environment. The conclusions provide an overall picture of the examined sectors’ potential future as a whole and by defined sub-sectors of the construction industry. The recognition of future trends in different areas of the construction industry can be applied as a means for an industry actor’s decision making and in estimating the types of construction that are likely to grow or decline. Finally, based on the analyzed data and conclusions, the commissioning company is provided with a brief SWOT analysis, that provides additional tools for decision making and planning processes regarding the future.

Tutkimuksessa kuvataan yksityisten lääkäripalveluyritysten kilpailuetuja. Tutkimus ottaa kantaa taloustieteissä esiintyviin kilpailuetuteorioihin ja pyrkii löytämään toimialan kilpailuvoimia. Tutkimuksessa syvennytään myös toimialan rakenteeseen, sen merkitykseen kilpailuedun luomisessa sekä peilataan alan kirjallisuutta toimialan todelliseen rakenteeseen. Empiirisen aineiston kerääminen toteutetaan teema-haastattelumenetelmällä. Haastattelu on laadullinen tutkimus, jonka tarkoitus on paljastaa toimialan kilpailuvoimia ja selvittää, miten yritykset säilyttävät kilpailuetujaan. Teoreettisena viitekehyksenä tutkimuksessa käytetään viiden kilpailuvoiman mallia ja yrityksen resurssiperustaista näkemystä. Tutkimus osoittaa toimialan olevan monitahoinen ja kompleksinen kokonaisuus, joka koostuu monia toisiaan tukevista osista. Yritykset tuottavat lääkäripalveluiden lisäksi myös muita palveluita, jotka osaltaan tukevat kilpailuetua tutkittavassa liiketoiminnassa. Haastattelujen perusteella voidaan todeta kilpailuetujen syntyvän tekijöistä kuten sosiaaliset prosessit, jotka syntyvät yrityksissä jokapäiväisen toiminnan sivutuotteena. Lisäksi tärkeitä ovat yritysten ja asiakkaiden väliset suhteet sekä yrityksen suhteet omaan työvoimaansa, jolla palvelut tuotetaan.
