Factprs affecting private forest owners' choice of business partner : a market survey of VIDA's core values

I Sverige är omkring hälften av den produktiva skogsmarken privatägd. VIDA, som är Sveriges största privatägda sågverkskoncern, anskaffar främst sina råvaror genom köp från privata skogsägare i södra Sverige. För att bli en attraktiv virkesköpande organisation har VIDA utvecklat kärnvärden. Eftersom det finns få studier som undersöker vad privata skogsägare efterfrågar hos virkesköpande organisationer var syftet med denna studie att undersöka om VIDA:s kärnvärden är viktiga för skogsägarna när de väljer samarbetspartner och om skogsägarna uppfattar VIDA så som VIDA önskar uppfattas. I studiens syfte ingick även att utföra en SWOT-analys och att undersöka om det finns skillnader i uppfattningen av VIDA mellan nuvarande och äldre leverantörer samt mellan VIDA:s olika regioner. Studien baserades på en enkätundersökning där 1 500 enkäter skickades ut till VIDA:s leverantörer. Totalt inkom 616 svar. Resultatet visar att respondenterna främst fokuserar på den personliga kontakten med virkesinköparen, priserna och tidigare utförda arbeten när de väljer samarbetspartner. De kärnvärden som flest respondenter tyckte var viktigast var att företaget håller vad de lovar, har professionella entreprenörer och att de har en kontaktperson genom hela affären. En klassificering av kärnvärdena visade att tio klassades som viktiga, fyra som intermediära och fem som oviktiga. Över hälften av respondenterna ansåg att VIDA uppfyllde 18 av 19 kärnvärden ganska eller mycket bra. Resultatet visade att det fanns ett samband mellan leverantörstyp, nuvarande eller äldre leverantörer, och inställningen till hur väl VIDA uppfyllde kärnvärdena. Det fanns inget tydligt samband mellan leverantörernas regiontillhörighet och inställningen till VIDA. SWOT-analysen visade på tio nyckelstyrkor, fem överflödiga styrkor och fyra styrkor i gränslandet mellan överflödiga-/nyckelstyrkor. Analysen visade inga svagheter. För de flesta skogliga åtgärderna finns det möjlighet till fler framtida uppdrag för VIDA. Ett hot för VIDA är lågkonjunkturer.In Sweden, about 50 percent of the productive forest land is owned by private forest owner. VIDA which is the largest privately owned sawmill group in Sweden procures its raw materials primarily through purchases from private forest owners in southern Sweden. To become an attractive timber buying organization VIDA has developed core values. Since there are a few studies that examine what private forest owners require from timber purchasing organizations, the aim of this study was to investigate whether VIDA's core values are important for forest owners when they choose partner and if the forest owners perceive VIDA as they want to be perceived. The aim of the study was also to perform a SWOT analysis and to examine whether there are differences in the perception of VIDA between current and older suppliers and between different regions. The study was based on a survey where 1 500 questionnaires were sent to VIDA's suppliers, and a total of 616 responses were received. The results show that respondents primarily look at the personal contact with the timber buyer, prices and the previously work when they choose a partner. The core values that most respondents thought were most important were that the company keeps its promises, has professional contractors and that they have one contact person through the full contract. A classification of the core values showed that ten were classified as important, four as intermediate and five as unimportant. Over 50 percent of the respondents found that VIDA performed 18 of the 19 core values fairly or very well. The result showed that there was a relationship between the supplier type, current or older suppliers, and attitudes to how well VIDA fulfill its core values. There was no clear connection between the suppliers' regional affiliation and attitude to VIDA. The SWOT analysis showed ten key strengths, five superfluous strengths and four strengths on the border between superfluous and key strengths. The analysis showed no weaknesses. For the most forest operations, VIDA has opportunities to do more assignments in the future. A threat for VIDA is economic recessions

Evaluación de diferentes técnicas moleculares para la identificación Oenococcus oeni en mosto y vino

[ES] La comunidad de microorganismos utilizados en la elaboración de vino es muy diversa. Este trabajo se va a centrar en la especie Oenococcus oeni. Oenococcus es un género de bacterias Gram positivas, dentro del cual se encuentra la bacteria más conocida, Oenococcus oeni cuya misión es llevar a cabo la fermentación maloláctica que aporta una composición, color y unas características organolépticas que definen la calidad en muchos vinos, especialmente en los tintos. El vino presenta una dinámica microbiana diversa que cambia desde el mosto hasta transcurrir la fermentación alcohólica y maloláctica. En los últimos años, se han desarrollado técnicas moleculares que permiten identificar los microorganismos en el vino para controlar el proceso de vinificación y así obtener el vino deseado. En este trabajo se van a evaluar las principales técnicas moleculares para la identificación de Oenococcus oeni y su identificación frente a las demás bacterias en el vino. En este estudio se han descrito las principales técnicas moleculares divididas en dos apartados, el primero para la identificación de la bacteria Oenococcus oeni como especie y el segundo para la identificación de sus cepas. Cada apartado a su vez se ha dividido en tres secciones según se realizaba el análisis completo o parcial del genoma bacteriano. Para la identificación a nivel de especie se ha expuesto las técnicas de FISH, 16S-ARDRA, DGGE, PCR especie-específica y a nivel de cepa se ha puntualizado las técnicas de MLST, ITS-PCR, AFLP, RAPD y PCR en tiempo real. Los estudios más recientes han demostrado que el PCR en tiempo real tiene muchas ventajas respecto a la PCR tradicional para la identificación a nivel de especie y cepa de la bacteria Oenococcus oeni.[EN] The community of microorganisms used in winemaking is very diverse. This study is focussed on Oenococcus oeni species. Oenococcus is a genus of Gram positive bacteria, which is the best-known bacterium, Oenococcus oeni whose mission is to carry out malolactic fermentation that provides a composition, color and organoleptic characteristics that define the quality of many wines, especially red ones. The wine presents a diverse microbial dynamics that change from the must to the alcoholic and malolactic fermentation. In recent years, molecular techniques have been developed that allow the identification and control of microorganisms in wine to control the winemaking process and thus obtain the desired wine. In this project the main molecular techniques for the identification of Oenococcus oeni and its identification against the other bacteria in wine will be evaluated. In this study, the main molecular techniques are divided into two sections have been described, the first one for the identification of the bacterium Oenococcus oeni as a species and the second one for the identification of its strains. Each section has also been divided into three sections according to the complete or partial analysis of the bacterial genome. For the identification at species level, the techniques of FISH, 16S-ARDRA, DGGE, species-specific PCR have been exposed and at strain level the techniques of MLST, ITS-PCR, AFLP, RAPD and real-time PCR have been specified. The most recent studies have shown that real-time PCR has many advantages over traditional PCR for the species and strain level identification of the Oenococcus oeni bacterium.Piquer Fideli, P.

The landscape architect, the artist and the creative process : a study on the cooperation between landscape architect and artist in the process of designing public spaces

Det här arbetet sammanfattar ett urval faktorer i den gemensamma gestaltningsprocessen som är viktiga för att dialogen och den kreativa processen mellan landskapsarkitekt/arkitekt och konstnär ska nå ett önskvärt resultat. Arbetet inleds med en kort historik över de två yrkenas verksamhet i Sverige och redovisar sedan en litteraturstudie som berör vilka faktorer som påverkar den gemensamma gestaltningsprocessen och den ömsesidiga kommunikationen. Vidare redovisas intervjuer genomförda med sex konstnärer, landskapsarkitekter/arkitekter och landskaps-arkitekter vilka medverkat i samverkansprojekt utförda under Statens Konstråds uppdrag; Samverkan om gestaltning av offentliga miljöer. Studien visar att faktorer som påverkar samverkan är ömsesidig förståelse för gestaltningsprocessen, användning av skissen som kommunikationsverktyg, samverkan i ett tidigt skede, en förståelse för roller och förväntningar, vikten av möten samt en gemensam kunskap hos yrkesgrupperna. Den övergripande tendens som kan utläsas är att behovet finns hos konstnärer att få en större förståelse för byggprocessen och dess praktiska aspekt samt för de kompromisser som kommer med samverkan. Landskapsarkitekten/arkitekten uttrycker en önskan om utöka sin kunskap om olika konstnärliga tillvägagångssätt för att kunna möta konstnären med större förståelse och ha möjlighet att verka i samma begreppsvärld. Resultatet i studien tyder på ett behov av ökad gemensam kunskap hos yrkesgrupperna.This study aims to summarize a number of important factors that facilitates dialogue and creativity in the design process between architect/landscape architect and artist. The study partly consists of a literature study that touches upon the factors that affect the common design process and the mutual communication between the professions. Furthermore the study accounts for interviews executed with six artists, landscape architects and architects. All of whom have cooperated in the collaboration-projects initiated by the Swedish state art council under the governmental assignment: Collaboration through design of public spaces. During the interviews the participants reflect on which factors that affect the concerted process and possible improvements to the process as it is today. The study shows that the factors which alter the collaboration are; mutual understanding of the design process, the use of sketching as a communication tool, collaboration early on in the process, mutual understanding of roles, stereotypes and expectations, the importance of meeting and mutual knowledge and education possibilities. The overall tendency seems to be that there is a need amongst artist to gain an extended understanding about both the building process and its practical aspects and the compromising aspects that comes with collaboration. Architects on the other hand need to gain knowledge about different artistic approaches to be able to meet the artist on equal and professional terms. Generally the study shows that there is a need of common education and shared knowledge between the professional groups

Methylmercury in outlet from wetlands

Antropogen utsläpp av metylkvicksilver har i flera århundranden skett till atmosfären och vattensystem. I Sverige har ansträngningar för att minska kvicksilverutsläpp pågått sedan 1970-talet, men problem med kvicksilverförgiftad fisk kvarstår. Problemen med kvicksilver uppstår när grundformen syntetiseras till en organiskform, metylkvicksilver. Metylkvicksilver kan ta sig över cellmembran och stanna kvar i biologiskvävnad där den påverkar enzymatiska funktioner negativt. Studier för att utreda var omvandlingen till metylkvicksilver sker har identifierat våtmarker som källor. Tjerngren I. har samlat in data från åtta olika våtmarkstyper i hela Sverige och kom fram till att sju av de åtta våtmarkerna hade en nettoproduktion av metylkvicksilver. I samband med Tjerngrens våtmarksstudie samlades data från våtmarkernas utlopp in vid olika tidpunkter på året. Syftet med föreliggande studie är att utreda säsongsvariationerna för metylkvicksilver och andra vattenkemiska variabler i utloppsvattnet, samt undersöka om mätningar i våtmarkers utlopp säger något om metyleringsprocessen som sker i omgivande våtmark. Metylkvicksilverhalten i våtmarkernas utlopp var signifikant korrelerad till halterna i markens porvatten. Årscykeln för metylkvicksilverhalt och årscykeln för lufttemperatur följde varandra mycket nära under året, förutom under vintern. Det fanns ingen uppenbar tidsfördröjning mellan de två kurvorna. Halterna av metylkvicksilver och löst organiskt material (DOC) var starkt korrelerade och haltkurvorna följdes åt tämligen väl under perioden vår till höst. Sulfathaltens utveckling under vår och sommar var negativt korrelerad med metylkvicksilverhalten, sulfatet minskade när metylkvicksilvret ökade. Sammantaget tyder utvärderingen av vattenanalyserna på att processer som sker i våtmarken syns i dess utlopp.The problem of mercury occurs when the basic form is synthesized into an organic form, methylmercury. Methylmercury can cross the cell membrane where it affects the enzymatic functions negatively. Studies to investigate the conversion to methylmercury have identified wetlands as sources. Tjerngren. I collected data from eight different wetland types in Sweden and found that seven out of eight wetlands had a net production of methylmercury. In connection with Tjerngrens wetland study, data were collected from wetland outlets at different times of the year. The aim of the present study is to investigate the seasonality of methylmercury and other water chemistry variables in the wetland outlets and examine whether measurements of wetland outlet say something about the methylation reaction that is going on in the surrounding wetlands. Methylmercury concentrations in wetland outlets were significantly correlated with concentrations in soil pore water. Annual cycle for methylmercury concentrations and annual cycle of air temperature followed each other very closely during the year, except during the winter. There was no apparent time delay between the two curves. Concentrations of methylmercury and dissolved organic matter (DOC) were highly correlated and concentration curves followed each other fairly well during the period from spring to autumn. The development of the sulfate concentrations in spring and summer were negatively correlated with methylmercury, sulfate levels decreased when methylmercury levels increased. Overall, the evaluation of the water analyzes tells us that processes occurring in the wetland is visible in the outlet

Enhancing Collaboration and Creative Thinking Skills through Technology Preparedness in a Mixed Learning Environment

This study aimed to investigate the technology preparedness of Grade 10 students as to their collaborative and creative thinking skills. Specifically, it determined the extent of technology preparedness in mixed learning environment in terms of performance expectancy, effort expectancy, facilitating conditions, and social influence, the level of collaboration and creative thinking skills in learning science and the relationships of technology preparedness as to collaborative and creative thinking skills. The study employed descriptive correlational research through the utilization of self-made questionnaire to measure the students’ technology preparedness. Meanwhile, the assessment of the collaboration and creative thinking skills, different activities with rubrics were used. The findings revealed that the students are were moderately prepared in technology but they were proficient in learning science. The study further showed significant relationship between the student’s technology preparedness and some skills in collaboration and creative thinking skills. With this finding, it is recommended that collaborative and creative thinking skill activities as a teaching method be used in classes across levels and programs

Lack of Detectable HIV-1–Specific CD8+ T Cell Responses in Zambian HIV-1–Exposed Seronegative Partners of HIV-1–Positive Individuals

Human immunodeficiency virus type 1 (HIV-1)–specific T cell responses were characterized in a blinded study involving infected individuals and their seronegative exposed uninfected (EU) partners from Lusaka, Zambia. HIV-1–specific T cell responses were detected ex vivo in all infected individuals and amplified, on average, 27-fold following in vitro expansion. In contrast, no HIV-1–specific T cell responses were detected in any of the EU partners ex vivo or following in vitro expansion. These data demonstrate that the detection of HIV-1–specific T cell immunity in EU individuals is not universal and that alternative mechanisms may account for protection in these individuals

Longitudinal study about the adherence to Mediterranean Diet patterns in Health Sciences students

Introducción: El período universitario suele ser el momento en que los estudiantes asumen por primera vez su propia alimentación y pueden adquirir hábitos que repercutirán en su futura salud. Se analiza la evolución del índice de masa corporal (IMC) y adherencia a la Dieta Mediterránea en estudiantes de Ciencias de la Salud estudiando los efectos de la formación recibida en el primer curso y en el segundo curso académico. Material y Métodos: Estudio piloto sobre el seguimiento de 124 estudiantes de Ciencias de la Salud de la Universidad CEU Cardenal Herrera (grados de Enfermería y Fisioterapia), mediante el cuestionario KIDMED en primer curso y durante el segundo curso académico, valorando los cambios en la adherencia a la Dieta Mediterránea y posibles factores asociados (sexo, grado de procedencia, comensalidad, estado de IMC y valoración de la adherencia previa). Resultados: Se encuentra buena correlación entre IMC inicial y final (r2=0,848; p<0,001) y valoración KIDMED inicial y final (r2=0,691; p<0,001). El IMC no muestra diferencias significativas al recibir la formación. Se produce un incremento significativo de la valoración KIDMED, mayor en los alumnos de Enfermería (p=0,045). El 50,8% mejora su adherencia a la dieta, tanto en el análisis bivariante como multivariante de regresión logística binaria, únicamente se observa asociación inversa a la adherencia inicial (OR=1,68[1,35–2,08]; IC=95%; p<0,001). Conclusiones: Se observó una ligera mejoría en la adherencia a la Dieta Mediterránea cuando los estudiantes cursaban segundo curso de Ciencias de la Salud. Por ello, incluir información científica acerca de hábitos dietéticos y estilos de vida saludables a los universitarios contribuye a mejorar sus propios hábitos y poderlos promover entre sus futuros pacientes.Introduction: The university period is usually the moment when students assume their own diet for the first time and can acquire habits that will affect their future health. The evolution of the nutritional status of the body mass index (BMI) and adherence to the Mediterranean Diet in Health Sciences students in the Nursing and Physiotherapy degrees is studied by studying the effects of the training received in the first year and in the second academic course on Dietetics and Nutrition. Material and Methods: Pilot study on the follow-up of 124 students of Health Sciences of the Universidad CEU Cardenal Herrera (Nursing and Physiotherapy degrees), by means of the KIDMED questionnaire before and after studying a subject of Nutrition in first year and during the second academic year, assessing the changes in the adherence to the Mediterranean Diet and possible associated factors (sex, degree of origin, commensality, state of nutrition through BMI and assessment of previous adherence). Results: A good correlation was found between initial and final BMI (r2=0.848, p<0.001) and initial and final KIDMED assessment (r2=0.691, p<0.001). The nutrition status BMI does not show significant differences when receiving the training. There was a significant increase in KIDMED assessment, higher in Nursing students (p=0.045). 50.8% improves its adherence to the diet, both in the bivariate and multivariate analysis of binary logistic regression, only an inverse association with the initial adherence is observed (OR=1.68[1.35–2.08]; IC=95%, p<0.001). Conclusions: A slight improvement in the adherence of the students’ diet to the Mediterranean Diet was observed when the students were taking a second course in Health Sciences and had received nutrition training. Therefore, include scientific information about dietary habits and healthy lifestyles to college students help improve their own habits and promote them among their future patients
