Cattleya granulosa Lind is a large and endemic orchid in Atlantic Forest fragments in Northeast Brazil. The facility of collecting, uniqueness of their flowers, which have varying colors between green and reddish brown, and distribution in coastal areas of economic interest make their populations a constant target of predation, which also suffer from environmental degradation. Due to the impact on their populations, the species is threatened. In this study, we evaluate the levels of spatial aggregation in a preserved population, analyze the phylogenetic relationships of C. granulosa Lindl. with four other Laeliinae species (Brassavola tuberculata, C. bicolor, C. labiata and C. schofieldiana) and also to evaluate the genetic diversity of 12 remaining populations of C. granulosa Lindl. through ISSR. There was specificity of epiphytic C. granula Lindl. with a single host tree, species of Eugenia sp. C. granulosa Lindl. own spatial pattern, with the highest density of neighbors within up to 5 m. Regarding the phylogenetic relationships and genetic patterns with other species of the genus, C. bicolor exhibited the greatest genetic diversity (HE = 0.219), while C. labiata exhibited the lowest level (HE = 0.132). The percentage of genetic variation among species (AMOVA) was 23.26%. The principal component analysis (PCA) of ISSR data showed that unifoliate and bifoliolate species are genetically divergent. PCA indicated a close relationship between C. granulosa Lindl. and C. schofieldiana, a species considered to be a variety of C. granulosa Lindl. by many researchers. Population genetic analysis using ISSR showed all polymorphic loci. The high genetic differentiation between populations (ФST = 0.391, P < 0.0001) determined the structure into nine groups according to log-likelihood of Bayesian analysis, with a similar pattern in the dendrogram (UPGMA) and PCA. A positive and significant correlation between geographic and genetic distances between populations was identified (r = 0.794, P = 0.017), indicating isolation by distance. Patterns of allelic diversity suggest the occurrence of population bottlenecks in most populations of C. granulosa Lindl. (n = 8). Genetic data indicate that enable the maintenance of genetic diversity of the species is complex and is directly related to the conservation of different units or groups that are spatially distant.

Research on women prisoners and drug use is scarce in our context and needs theoretical tools to understand their life paths. In this article, I introduce an intersectional perspective on the experiences of women in prison, with particular focus on drug use. To illustrate this, I draw on the life story of one of the women interviewed in prison, in order to explore the axes of inequality in the lives of women in prison. These are usually presented as accumulated and articulated in complex and diverse ways. The theoretical tool of intersectionality allows us to gain an understanding of the phenomenon of women prisoners who have used drugs. This includes both the structural constraints in which they were embedded and the decisions they made, considering the circumstances of disadvantage in which they were immersed. This is a perspective which has already been intuitively present since the dawn of feminist criminology in the English-speaking world and can now be developed further due to new contributions in this field of gender studies.

Numerous studies show that increasing species richness leads to higher ecosystem productivity. This effect is often attributed to more efficient portioning of multiple resources in communities with higher numbers of competing species, indicating the role of resource supply and stoichiometry for biodiversity-ecosystem functioning relationships. Here, we merged theory on ecological stoichiometry with a framework of biodiversity-ecosystem functioning to understand how resource use transfers into primary production. We applied a structural equation model to define patterns of diversity-productivity relationships with respect to available resources. Meta-analysis was used to summarize the findings across ecosystem types ranging from aquatic ecosystems to grasslands and forests. As hypothesized, resource supply increased realized productivity and richness, but we found significant differences between ecosystems and study types. Increased richness was associated with increased productivity, although this effect was not seen in experiments. More even communities had lower productivity, indicating that biomass production is often maintained by a few dominant species, and reduced dominance generally reduced ecosystem productivity. This synthesis, which integrates observational and experimental studies in a variety of ecosystems and geographical regions, exposes common patterns and differences in biodiversity-functioning relationships, and increases the mechanistic understanding of changes in ecosystems productivity.

Background and Problem: Despite the exploding increase in revenue by more than 500 percent (1996-2014) among European football clubs, the operating profit in the “big five” leagues are, paradoxically, inexistent or very low. Hence, there is a need for more transparent financial reporting in European football. To preserve the game’s well-being and establish a sustainable future, UEFA introduced Financial Fair Play (FFP) back in 2010 as a part of their club licensing requirements. The transparency that FFP is intended to improve is however only disclosed to UEFA and its member associations, which is only one of many stakeholders. In times of financial turmoil in European football clubs, where fair play and sustainability is frequently discussed since the implementation of FFP, one could ask; is it really fair play that not all European football clubs are obligated to be transparent towards all their stakeholders and supporters? Purpose: The purpose of this thesis is to, from a supporter perspective, look at how transparent European football clubs’ financial disclosure is. Methodology: The research has elements of both a deductive and an inductive approach and uses a disclosure checklist with a cross-sectional design, in order to measure disclosure transparency.  Empirical Results and Conclusion: Even though the empirical findings proved that financial reporting transparency are present within European football, the conclusion is that the financial reporting is generally not transparent within the industry.

Introduktion: Stroke är en av de stora folksjukdomarna och en av de ledande dödsorsakerna i Sverige. Det är en vanlig orsak till funktionsnedsättning och påverkar personen både fysiskt och psykiskt. Syfte: Litteraturstudiens syfte var att belysa upplevelse av psykisk ohälsa efter en stroke, ur ett patientperspektiv. Metod: Den metod som användes var en litteraturstudie, med deduktiv ansats. Med hjälp av relevanta sökord identifierades elva artiklar i databaserna CINAHL och PubMed, som sedan genomgick en kvalitetsgranskning och slutligen utgjorde resultatet. Resultat: Presenterades i tre kategorier utifrån en modifiering av referensramen enligt följande: Avsaknad av emotionellt välbefinnande, Avsaknad av socialt välbefinnande, Avsaknad av psykisk välbefinnande. Dessa kategorier visade upplevelser av psykisk ohälsa på olika sätt och hur de påverkade patienten. Slutsats: Upplevelser av psykisk ohälsa var vanligt förekommande hos patienterna. Då fokus låg på den fysiska rehabiliteringen hamnade den psykiska dimensionen i skymundan. Det är av stor vikt att sjuksköterskan uppmärksammar och möter dessa upplevelser av psykisk ohälsa i ett tidigt utvecklingsskede, för att undvika vidareutveckling mot mer allvarliga psykiatriska tillstånd.

Tässä tutkielmassa tutkitaan lukion pitkän matematiikan pakollisia kursseja ja on keskitytty juuri sellaisiin matematiikan alueisiin, joita voi ratkaista wxMaximan avulla. Tutkielmassa ei ollenkaan opeteta wxMaximan käyttöä, mutta ohessa on kirjoittajan tekemä kandin työ, wxMaximan pikaopas, jossa neuvotaan wxMaximan käyttöä. Tutkielmasta on kuitenkin jätetty pois geometrian, trigonometrian ja vektorien osuudet, koska kolmioita ja vektoreita on hankala piirtää wxMaximan avulla. Näin ollen myös trigonometriset laskut on jätetty pois raja-arvon, derivaatan ja integraalin yhteydestä. Tutkielmasta on jätetty pois myös lukujonot, lukuteoria ja todistaminen. Sen sijaan tutkielmaan on otettu pitkän matematiikan syventävistä kursseista puolisuunnikassääntö, Newtonin menetelmä ja laajennettu raja-arvon sekä integraalin osa-alueita. Ekstra asiaa kohdissa käsitellään asioita, jotka ovat kokonaan lukion pitkän matematiikan kurssien opetuksen ulkopuolella. Tutkielman toisessa luvussa kerrotaan, mitä lukion opetussuunnitelman perusteet eli OPSin (2015) kurssien sisältöjä, tutkielman luvat vastaavat. Kurssien OPS (2015) tavoitteissa kerrotaan vain se osuus OPSin kurssien sisällöistä, joita tässä tutkielmassa käsitellään. Mukaan on laadittu myös tuntisuunnitelma, kuinka monta tuntia mihinkin lukuun voisi käyttää aikaa, jos tutkielmaa käytettäisiin pitkän matematiikan kertauskurssina lukiossa. Tutkielman lopussa on kaikkiin tehtäviin vastaukset. Ensin löytyy pelkät loppuvastaukset ja sitten on täydelliset vastaukset, jotka on tehty wxMaximalla. Varmaan moniin laskuihin löytyisi toinenkin tapa ratkaista ne. Tällaisen tutkielman tekeminen on ajan kohtainen, sillä vuonna 2019 matematiikan yo-kirjoitukset muuttuvat sähköiseen muotoon. wxMaxima on valittu juuri yhdeksi ohjelmaksi, jota voi käyttää sähköisissä kirjoituksissa.

Background: increasing numbers of patients are surviving critical illness, but survival may be associated with a constellation of physical and psychological sequelae that can cause on going disability and reduced health-related quality of life. Limited evidence currently exists to guide the optimum structure, timing, and content of rehabilitation programmes. There is a need to both develop and evaluate interventions to support and expedite recovery during the post-ICU discharge period. This paper describes the construct development for a complex rehabilitation intervention intended to promote physical recovery following critical illness. The intervention is currently being evaluated in a randomised trial (ISRCTN09412438; funder Chief Scientists Office, Scotland). Methods: the intervention was developed using the Medical Research Council (MRC) framework for developing complex healthcare interventions. We ensured representation from a wide variety of stakeholders including content experts from multiple specialties, methodologists, and patient representation. The intervention construct was initially based on literature review, local observational and audit work, qualitative studies with ICU survivors, and brainstorming activities. Iterative refinement was aided by the publication of a National Institute for Health and Care Excellence guideline (No. 83), publicly available patient stories (Healthtalkonline), a stakeholder event in collaboration with the James Lind Alliance, and local piloting. Modelling and further work involved a feasibility trial and development of a novel generic rehabilitation assistant (GRA) role. Several rounds of external peer review during successive funding applications also contributed to development. Results: the final construct for the complex intervention involved a dedicated GRA trained to pre-defined competencies across multiple rehabilitation domains (physiotherapy, dietetics, occupational therapy, and speech/language therapy), with specific training in post-critical illness issues. The intervention was from ICU discharge to 3 months post-discharge, including inpatient and post-hospital discharge elements. Clear strategies to provide information to patients/families were included. A detailed taxonomy was developed to define and describe the processes undertaken, and capture them during the trial. The detailed process measure description, together with a range of patient, health service, and economic outcomes were successfully mapped on to the modified CONSORT recommendations for reporting non-pharmacologic trial interventions. Conclusions: the MRC complex intervention framework was an effective guide to developing a novel post-ICU rehabilitation intervention. Combining a clearly defined new healthcare role with a detailed taxonomy of process and activity enabled the intervention to be clearly described for the purpose of trial delivery and reporting. These data will be useful when interpreting the results of the randomised trial, will increase internal and external trial validity, and help others implement the intervention if the intervention proves clinically and cost effective.

Forest trees, like oaks, rely on high levels of genetic variation to adapt to varying environmental conditions. Thus, genetic variation and its distribution are important for the long-term survival and adaptability of oak populations. Climate change is projected to lead to increased drought and fire events as well as a northward migration of tree species, including oaks. Additionally, decline in oak regeneration has become increasingly concerning since it may lead to decreased gene flow and increased inbreeding levels. This will in turn lead to lowered levels of genetic diversity, negatively affecting the growth and survival of populations. At the same time, populations at the species’ distribution edge, like those in this study, could possess important stores of genetic diversity and adaptive potential, while also being vulnerable to climatic or anthropogenic changes. A survey of the level and distribution of genetic variation and identification of potentially adaptive genes is needed since adaptive genetic variation is essential for their long-term survival. Oaks possess a remarkable characteristic in that they maintain their species identity and specific environmental adaptations despite their propensity to hybridize. Thus, in the face of interspecific gene flow, some areas of the genome remain differentiated due to selection. This characteristic allows the study of local environmental adaptation through genetic variation analyses. Furthermore, using genic markers with known putative functions makes it possible to link those differentiated markers to potential adaptive traits (e.g., flowering time, drought stress tolerance). Demographic processes like gene flow and genetic drift also play an important role in how genes (including adaptive genes) are maintained or spread. These processes are influenced by disturbances, both natural and anthropogenic. An examination of how genetic variation is geographically distributed can display how these genetic processes and geographical disturbances influence genetic variation patterns. For example, the spatial clustering of closely related trees could promote inbreeding with associated negative effects (inbreeding depression), if gene flow is limited. In turn this can have negative consequences for a species’ ability to adapt to changing environmental conditions. In contrast, interspecific hybridization may also allow the transfer of genes between species that increase their adaptive potential in a changing environment. I have studied the ecologically divergent, interfertile red oaks, Quercus rubra and Q. ellipsoidalis, to identify genes with potential roles in adaptation to abiotic stress through traits such as drought tolerance and flowering time, and to assess the level and distribution of genetic variation. I found evidence for moderate gene flow between the two species and low interspecific genetic differences at most genetic markers (Lind and Gailing 2013). However, the screening of genic markers with potential roles in phenology and drought tolerance led to the identification of a CONSTANS-like (COL) gene, a candidate gene for flowering time and growth. This marker, located in the coding region of the gene, was highly differentiated between the two species in multiple geographical areas, despite interspecific gene flow, and may play a role in reproductive isolation and adaptive divergence between the two species (Lind-Riehl et al. 2014). Since climate change could result in a northward migration of trees species like oaks, this gene could be important in maintaining species identity despite increased contact zones between species (e.g., increased gene flow). Finally I examined differences in spatial genetic structure (SGS) and genetic variation between species and populations subjected to different management strategies and natural disturbances. Diverse management activities combined with various natural disturbances as well as species specific life history traits influenced SGS patterns and inbreeding levels (Lind-Riehl and Gailing submitted).
