Nordliga landskap : "Tillämpning av den europeiska landskapskonventionen i kommunerna på Nordkalotten" - Konferensen 7.-9.9.2011, Enare, Finland

För att kunna nå de uppsatta målen för den europeiska landskapskonventionen anordnades en internationell europeisk konferens den 7–9 september 2011 i Enare. Konferensen var främst inriktad på att öka kunskapen om den europeiska landskapskonventionen och de möjligheter och behov den ger vad gäller det praktiska planeringsarbetet, särkilt på kommunnivå. Den här rapport är samlat artikel skrev av ledande expertes som var föreläsare i konferensen. Vi hoppas att den här rapport underlättar det praktiska arbetet för planerarna av de här områdena och inspirerar kommunerna att genomföra sina framtidsplaner enligt den europeiska landskapskonventionen. Publikationen finns tillgänglig på fem olika språk: finska, svenska, norska, nordsamiska och engelska. Naturen på Nordkalotten återspeglar på bred front de gemensamma karaktäristiska dragen, såsom de fantastiska älvlandskapen och de vackra fjälltrakterna formade av samekulturen och renskötseln. Turism, energiproduktion, gruvnäring och utbyggnad av infrastruktur leder till nya och mångfacetterade utmaningar för dem som är ansvariga för områdena. Kommunerna behöver kunskap och stöd för att kunna förverkliga de allt mer komplexa planerna i framtiden, så att de unika och värdefulla särdragen kan bevaras. Landskapsskyddet och -vården genomförs i landskapsområdena via områdesplanering och planering av markanvändning, i huvudsak genom planläggning och utarbetande av landskapsvårdsplaner. Kommunerna i Nordkalotten har egna, delvis olikartade metoder och praxis, på basis av vilka olika processer i anslutning till områdesanvändningen sköts. Kommunerna och kommuninvånarna har ett stort intresse att bevara och skydda den egna livsmiljön och att upprätthålla och öka områdets attraktionskraft. Landskapet ses ju i kommunerna som en av de viktigaste attraktionsfaktorerna som man inte vill förlora. Kommunernas ökade markanvändningsbehov med avseende på bland annat energiproduktionen, gruvindustrin och den växande turistnäringen skapar ett välgrundat behov av en planering med ännu fler dimensioner. Det är viktigt att lokala intressegrupper deltar i planeringen redan i början av processen. Mångsidigt samarbete mellan medborgare, aktörer och myndigheter kan minska eller hindra konflikter. En dialog mellan medborgare, organisationer och myndigheter har en stor inverkan på många projekts effekter på landskapet. Med hjälp av forskning får vi mer information om landskapen, deras betydelse och hur olika markanvändningsmetoder påverkar landskapen. Gemensamma erfarenheter och praktik, uppdelningen av kunnande (know-how) samt uppfattningen av bredare landkapshelheten dörbättrar tilsammans de möjligheterna att förverkliga målen som definierats i Europeiska landskapkonventionen.För att säkerställa att arbetet fortsätter upprättas en landskapssamarbetsgrupp på Nordkalottens område, som huvuduppgift är att utveckla landskapspolitiken och driva den framåt.

Chronic subdural hematoma: epidemiological and prognostic analysis of 176 cases

Objective : To characterize patients with chronic subdural hematoma undergoing surgery and to identify prognostic indicators. Methods : We conducted a retrospective analysis of patients diagnosed with chronic subdural hematoma (CSDH) undergoing surgical treatment. We analyzed: age, period from trauma to diagnostic imaging, pre and postoperative Glasgow coma scale, type of surgery, associated comorbidities, use of postoperative drainage and outpatient treatment. Results : The sample consisted of 176 patients, 126 male and 50 female patients (ratio 2.5 : 1), ages ranged from six months to 97 years, with an average of 59.3 years. CSDH was caused by trauma in 52% of patients, with the time from trauma to imaging averaging 25.05 days; 37.7% were hypertensive patients and 20% had a neurological disease. Eighty-five (48.3%) patients were elderly and altered consciousness was present in 63% of cases. Of the 91 (51.7%) non-elderly patients, 44% presented with headache, altered consciousness occurred in 40% and motor abnormalities in 27.5%. The CSDH was located on the right in 41%, left in 43% and bilaterally in 16% of patients. Conclusion : the change of consciousness was the most common clinical alteration in the elderly and headache in non-elderly. The most associated comorbidity was the arterial hypertension and the most frequent cause, head trauma. The trepanation with two oriffices associated with a closed drainage system was the most used operating, with high efficacy and low complication rate.

Quality enhancement in teacher education : Tanzanian teacher educators’ conceptions and experiences

The overall aim of this study was to investigate and examine teacher educators’ conceptions and experiences of quality of teacher education. The research interest therefore was two-fold: a) to deepen understanding of the concept quality and b) scrutinize experiences of teacher educators of quality enhancement. To achieve this ambition the study was conducted in the context of a newly established university college-based teacher education in Tanzania. Two research questions guided the study. The first focused on investigating how teacher educators conceived quality in the domain of teacher education and the second intended to explore teacher educators’ experiences of quality enhancement. The theoretical framework of the study centered on the concepts of teacher education, quality, and criteria for quality enhancement. Phenomenographic and phenomenological approaches under the main umbrella of qualitative research design were selected. Twenty five teacher educators participated in the study. Interviews were used for the collection of the data. The results of the first research question, in brief, indicate that teacher educators’ conceptions of quality are expressed in two main categories, namely, outstanding academic scholarship and adequate professional scholarship. Quality as outstanding academic scholarship was illustrated by two subcategories: excellence and positive transformation. While the former was composed of two aspects, the latter was demonstrated by three aspects. Quality as adequate professional scholarship was described in three sub-categories. The first was improved teaching competency, consisting of two aspects. The second was conscious research orientation, which is displayed by three aspects, and the last was enhancing the ability to reflect, represented by two aspects. The results of the second research question, which focused on exploring teacher educators’ experience of quality enhancement, were classified into two main categories of description: insufficient programs of teacher education and unsatisfactory professional development of teacher educators. From the two categories, the strengths, weaknesses, opportunities and challenges related to programs of educating teachers, particularly curriculum development and implementation, and the professional development of educators, were exposed. Since the ambition of conducting the study was to deepen the understanding by producing insight that would act as a platform for appraising and enhancing the quality of teacher education, the results hopefully can be used for the development of the quality of teacher education in Tanzania.

Arseeni ja elohopea maaperässä ja vesistöissä

Maapallon väestön kasvaessa ja tarpeen makealle vedelle, ruualle ja viljelymaalle noustessa on tärkeää alkaa kiinnittää entistä tarkemmin huomiota vesistöjen ja maaperän saastumiseen myrkyllisillä raskasmetalleilla. Erityisesti elohopea ja arseeni, jotka jo nyt vaikuttavat heikentävästi miljoonien ihmisten elämään eri puolilla maapalloa, on syytä ottaa huolelliseen tarkkailuun. Raskasmetallien päästölähteet voidaan jakaa kahteen luokkaan, luonnollisiin ja ihmisperäisiin. Ihmisperäisiin päästölähteisiin voidaan vaikuttaa muun muassa teollisuutta ja liikennettä koskevalla lainsäädännöllä. Luonnollisiin päästölähteisiin vaikuttaminen on huomattavasti haastavampaa, mutta niiden haittaa ihmisille on mahdollista pienentää muun muassa parempien vedenpuhdistustekniikoiden avulla. Tämän työn kirjallisuusosassa tullaan esittelemään erityyppisiä luonnossa esiintyviä arseenin ja elohopean yhdisteitä, suurimpia arseenin ja elohopean päästölähteitä, sekä näiden raskasmetallien haitallisia terveysvaikutuksia. Kokeellisessa osassa tullaan keskittymään arseenin analysointiin nestemäisistä näytteistä. Näytteinä käytettiin tuntemattomilta kaatopaikoilta otettuja suotovesinäytteitä, sekä Pien-Saimaan pintavesinäytteitä. Analyyseihin on käytetty ICP-AES laitteistoa sekä kapillaarielektroforeesia.

State of logistics and transport in the Baltic Sea region in 2025

The world’s pace of change is accelerating and new innovations, inventions and technologies come about every day. Change is unavoidable. It is difficult to keep up and even more difficult to prepare for the future. Even though it is not possible to know exactly what will happen in the future, by studying futures people can better anticipate what might lie ahead. By making decisions and realizing the consequences of their choices today, people and governments are able to actively decide how they will act in the future. Both opportunities and pitfalls lie ahead, which encourages actors to make more farsighted decisions. The Baltic Sea region is an interesting area for futures studies. It comprises 11 nations and more than 100 million inhabitants and entails countries with advanced, high-income economies, like Finland, Germany and Denmark, and developing economies, like Russia, Latvia and Lithuania. The western, eastern, northern and southern parts of the region are separated by the Baltic Sea, which at the same time represents a barrier and a facility for trade and travel between the countries belonging to the region The purpose of this study was to uncover the most probable future of transport and logistics in the Baltic Sea region in 2025 by using the Delphi method. Altogether 109 responses were collected in two separate instances from experts in all the Baltic Sea region countries, 56 of whom were defined as academic respondents and 53 of whom business respondents. Only minor differences in the opinions of academic and business experts were discovered, and the larger differences lie between eastern and western response groups. The Baltic Sea region is a very heterogeneous region and the division is clearest between East and West, which differ in political, economic, social, technological and environmental aspects. The probable future of the Baltic Sea region presented in this study is coherent with previous studies on the same subject. The future of the Baltic Sea region in terms of logistics and transport looks quite bright according to the experts who participated in the study. Trade volumes will grow and the importance of logistics and transport to the competitiveness of the region will increase. Respondents from eastern countries seemed to be more optimistic about the future in general. Most differences between opinions could be explained by the gap in technological and infrastructural development between the East and West. As eastern countries are less-developed in some parts of their economies, it is easier for them to improve the technical condition of infrastructure by merely catching up with the western countries.

Weed mapping using a machine vision system

Weed mapping is a useful tool for site-specific herbicide applications. The objectives of this study were (1) to determine the percentage of land area covered by weeds in no-till and conventionally tilled fields of common bean using digital image processing and geostatistics, and (2) to compare two types of cameras. Two digital cameras (color and infrared) and a differential GPS were affixed to a center pivot structure for image acquisition. Sample field images were acquired in a regular grid pattern, and the images were processed to estimate the percentage of weed cover. After calculating the georeferenced weed percentage values, maps were constructed using geostatistical techniques. Based on the results, color images are recommended for mapping the percentage of weed cover in no-till systems, while infrared images are recommended for weed mapping in conventional tillage systems.

Toimittajan oikeus uutisoida ja toimitustyötä sääntelevät normit

Luettaessa uutisia lehdestä harvoin pohditaan sitä, onko toimituksellisessa työssä noudatettu lakia ja alan eettisiä ohjeita. Lukija luottaa siihen, että sääntöjä noudatetaan, mutta näin ei aina ole. Käytettäessä materiaalia toiselta lehdeltä jätetään alkuperäinen lähde usein mainitsematta. Tämän tutkielman tarkoituksena on selvittää keskeiset tekijänoikeuslain pykälät ja käytännössä kaikkein keskeisimmät Journalistin ohjeet sanomalehden toimittajan työssä ja miten nämä säännöt pääosin ilmenevät. Suoritetun kyselytutkimuksen perusteella tekijänoikeuslain pykälä oikeus uutisoida toisen lehden uutinen ja Journalistin ohjeista sääntö, jonka mukaan sisältöratkaisut on tehtävä journalistisin perustein, ovat keskeisimpiä sääntöjä käytännön työssä. Tutkimuksessa näitä sääntöjä käsitellään oikeusdogmaattisin menetelmin kieliopillisen tulkinnan kautta sekä toimittajan työn näkökulmasta. Tutkimuksen lainsäädännöllisen viitekehyksen muodostavat Suomen perustuslaki, laki sananvapauden käyttämisestä joukkoviestinnässä, kansallinen tekijänoikeuslaki ja Journalistin ohjeet. Tämän vuoksi tutkimuksessa on aiheellista tarkastella myös sananvapautta ja tekijänoikeuslakia toimituksellisessa työssä sekä näiden suhdetta toisiinsa ja myös median rakenteellista ja toiminnallista muutosta.

Effect of the injection of an extract of Ascaris suum on macrophage activation during the early phase of Mycobacterium bovis BCG infection in C57Bl/6 mice

Injection of an Ascaris suum extract (Asc) affects both the humoral and cellular immune responses to unrelated antigens when it is co-administered with these antigens. In the present study we evaluated the effect of Asc on macrophage activation in the early phase of Mycobacterium bovis BCG (Pasteur strain TMCC 1173) infection in C57Bl/6 mice. C57Bl/6 mice were injected intraperitoneally (ip) with 0.1 mg BCG (BCG group) or BCG plus 1 mg Asc (BCG + Asc group). The peritoneal exudates were obtained at 2, 7 and 14 days after infection. The numbers of IFN-g-secreting cells were assessed by the ELISPOT assay. Nitric oxide (NO) production was measured by the Griess method and by the evaluation of NADPH diaphorase activity in the peritoneal exudates. The administration of Asc extract increased NADPH diaphorase activity (2 days: control = 0, BCG = 7%, BCG + Asc = 13%, and Asc = 4%; 7 days: control = 4, BCG = 13%, BCG + Asc = 21%, and Asc = 4.5%) and TNF-a levels (mean ± SD; 2 days: control = 0, BCG = 169 ± 13, BCG + Asc = 202 ± 37, and Asc = 0; 7 days: control = 0, BCG = 545 ± 15.5, BCG + Asc = 2206 ± 160.6, and Asc = 126 ± 26; 14 days: control = 10 ± 1.45, BCG = 9 ± 1.15, BCG + Asc = 126 ± 18, and Asc = 880 ± 47.67 pg/ml) in the early phase of BCG infection. Low levels of NO production were detected at 2 and 7 days after BCG infection, increasing at 14 days (mean ± SD; 2 days: control = 0, BCG = 3.7 ± 1.59, BCG + Asc = 0.82 ± 0.005, Asc = 0.48 ± 0.33; 7 days: control = 0, BCG = 2.78 ± 1.54, BCG + Asc = 3.07 ± 1.05, Asc = 0; 14 days: control = 0, BCG = 9.05 ± 0.53, BCG + Asc = 9.61 ± 0.81, Asc = 10.5 ± 0.2 (2 x 106) cells/ml). Furthermore, we also observed that Asc co-injection induced a decrease of BCG-colony-forming units (CFU) in the spleens of BCG-infected mice during the first week of infection (mean ± SD; 2 days: BCG = 1.13 ± 0.07 and BCG + Asc = 0.798 ± 0.305; 7 days: BCG = 1.375 ± 0.194 and BCG + Asc = 0.548 ± 0.0226; 14 days: BCG = 0.473 ± 0.184 and BCG + Asc = 0.675 ± 0.065 (x 102) CFU). The present data suggest that Asc induces the enhancement of the immune response in the early phase of BCG infection.

Amplification of 9q34 in childhood adrenocortical tumors: a specific feature unrelated to ethnic origin or living conditions

Adrenocortical tumors (ACT) in children under 15 years of age exhibit some clinical and biological features distinct from ACT in adults. Cell proliferation, hypertrophy and cell death in adrenal cortex during the last months of gestation and the immediate postnatal period seem to be critical for the origin of ACT in children. Studies with large numbers of patients with childhood ACT have indicated a median age at diagnosis of about 4 years. In our institution, the median age was 3 years and 5 months, while the median age for first signs and symptoms was 2 years and 5 months (N = 72). Using the comparative genomic hybridization technique, we have reported a high frequency of 9q34 amplification in adenomas and carcinomas. This finding has been confirmed more recently by investigators in England. The lower socioeconomic status, the distinctive ethnic groups and all the regional differences in Southern Brazil in relation to patients in England indicate that these differences are not important to determine 9q34 amplification. Candidate amplified genes mapped to this locus are currently being investigated and Southern blot results obtained so far have discarded amplification of the abl oncogene. Amplification of 9q34 has not been found to be related to tumor size, staging, or malignant histopathological features, nor does it seem to be responsible for the higher incidence of ACT observed in Southern Brazil, but could be related to an ACT from embryonic origin.

Effects of chronic ethanol treatment on monoamine levels in rat hippocampus and striatum

We studied the effects of ethanol on concentrations of noradrenaline (NE), dopamine (DA) and serotonin (5-HT) and their metabolites in rat hippocampus and striatum. Ethanol (2 or 4 g/kg, po, from a 20% aqueous solution) was administered daily to male Wistar rats (4-13 per group) for 30 days and animals were sacrificed 30 min or 48 h after the last administration. Monoamines were measured by HPLC and considered significant at P < 0.05. A 47% increase in 5-HT levels was observed in the hippocampus with 4 g/kg ethanol in the 30-min protocol. Ethanol (2 and 4 g/kg) decreased DA (2114.5 ± 126.4 and 1785.1 ± 234.2 ng/g wet tissue, respectively) and 3,4-dihydroxyphenylacetic acid (DOPAC, 1477.6 ± 132.1 and 1218.8 ± 271.7 ng/g wet tissue, respectively) levels, while the higher dose also decreased NE (159.8 ± 13.5), 5-HT (228.0 ± 46.8) and 5-hydroxy-3-indoleacetic acid (5-HIAA, 304.4 ± 37.2 ng/g wet tissue), in the striatum after a 48-h withdrawal as compared to controls (DA: 3063.9 ± 321.3; DOPAC: 2379.6 ± 256.0; NE: 292.8 ± 50.2; 5-HT: 412.4 ± 36.2; 5-HIAA: 703.9 ± 61.4 ng/g wet tissue). In the 30-min protocol, ethanol (2 or 4 g/kg) decreased striatal NE (66 and 70%) and DA (50 and 36%) levels. On the other hand, increases were seen in 5-HIAA (146 and 153%) and 5-HT (59 and 86%) levels. Ethanol (2 g/kg, po) increased the homovanillic acid (HVA)/DA ratio (129%) in the striatum in the 30-min protocol, while at the higher dose it increased the HVA/DA ratio in the 48-h protocol (61%). These results indicate alterations in monoamines, mainly in the striatum, after chronic ethanol, which are influenced by dose and by the length of time after the last drug administration.

Social inequality and perinatal health: comparison of three Brazilian cohorts

The objective of the present study was to estimate and compare social inequality in terms of three indicators, i.e., low birth weight (LBW), preterm birth (PTB) and small for gestational age (SGA) birth, in three birth cohorts. Two cohorts were from the city of Ribeirão Preto, where data were collected for all 6748 live born singletons in 1978/79 and for one third of live born singletons (2846) in 1994. The third cohort consisted of 2443 singletons born in São Luís over a period of one year (1997/98). In Ribeirão Preto, LBW and PTB rates increased in all social strata from 1978/79 to 1994. Social inequalities regarding LBW and PTB disappeared since the increase in these rates was more accelerated in the groups with higher educational level. The percentage of SGA infants increased over the study period. Social inequality regarding SGA birth increased due to a more intense increase in SGA births in the strata with lower schooling. In São Luís, in 1997/98 there was no social inequality in LBW or PTB rates, whereas SGA birth rate was higher in mothers with less schooling. We speculate that the more accelerated increase in medical intervention, especially due to the increase in cesarean sections in the more privileged groups, could be the main factor explaining the unexpected increase in LBW and PTB rates in Ribeirão Preto and the decrease or disappearance of social inequality regarding these perinatal indicators in the two cities.

Genetic variations of EBV-LMP1 from nasopharyngeal carcinoma biopsies: potential loss of T cell epitopes

To find Epstein-Barr virus (EBV) strains with genetic variations of EBV latent membrane protein 1 (EBV-LMP1) from nasopharyngeal carcinoma (NPC), the full-length DNA of LMP1 genes from 21 NPC biopsies obtained in Hunan province in southern China was amplified and sequenced. Our sequences were compared to those previously reported by the Clustal V method. Results showed that all 21 sequences displayed two amino acid changes most frequently in LMP1 of CD4+ T cell epitopes at codons 144 (F®I, 21/21) and 212 (G®S, 19/21) or (G®N, 2/21). We also show that type A EBV strain is prevalent in the cases of NPC from Hunan province with a 30-bp 18/21 deletion, and we highlight that this deletion resulted in loss of one of the CD4+ T cell-restricted epitopes. The other 3 sequences without this deletion all had a change at codon 344 (G®D). Furthermore, in the major epitope sequence of CD8+ T cells restricted by HLA-A2, all 21 sequences showed changes at codons 126 (L®F) and 129 (M®I). Our study discovered that one of the 21 sequence variations harbored a new change at codon 131 (W®C), and 5/21 specimens showed another novel change at codon 115 (G®A) in the major epitope sequence of CD8+ T cells restricted by HLA-A2. Our study suggests that these sequence variations of NPC-derived LMP1 may lead to a potential escape from host cell immune recognition, protecting latent EBV infection and causing an increase in tumorigenicity.

MMP-1/PAR-1 signal transduction axis and its prognostic impact in esophageal squamous cell carcinoma

The matrix metalloprotease-1 (MMP-1)/protease-activated receptor-1 (PAR-1) signal transduction axis plays an important role in tumorigenesis. To explore the expression and prognostic value of MMP-1 and PAR-1 in esophageal squamous cell carcinoma (ESCC), we evaluated the expression of two proteins in resected specimens from 85 patients with ESCC by immunohistochemistry. Sixty-two (72.9%) and 58 (68.2%) tumors were MMP-1- and PAR-1-positive, respectively, while no significant staining was observed in normal esophageal squamous epithelium. MMP-1 and PAR-1 overexpression was significantly associated with tumor node metastasis (TNM) stage and regional lymph node involvement. Patients with MMP-1- and PAR-1-positive tumors, respectively, had poorer disease-free survival (DFS) than those with negative ESCC (P = 0.002 and 0.003, respectively). Univariate analysis showed a significant relationship between TNM stage [hazard ratio (HR) = 2.836, 95% confidence interval (CI) = 1.866-4.308], regional lymph node involvement (HR = 2.955, 95%CI = 1.713-5.068), MMP-1 expression (HR = 2.669, 95%CI = 1.229-6.127), and PAR-1 expression (HR = 1.762, 95%CI = 1.156-2.883) and DFS. Multivariate analysis including the above four parameters identified TNM stage (HR = 2.035, 95%CI = 1.167-3.681), MMP-1 expression (HR = 2.109, 95%CI = 1.293-3.279), and PAR-1 expression (HR = 1.967, 95%CI = 1.256-2.881) as independent and significant prognostic factors for DFS. Our data suggest for the first time that MMP-1 and PAR-1 were both overexpressed in ESCC and are novel predictors of poor patient prognosis after curative resection. The MMP-1/PAR-1 signal transduction axis might be a new therapeutic target for future therapies tailored against ESCC.

Missale (C.ö.IV.9, Oripään missale II)

A (mainly votive) missal consisting of seven distinct parts. Put together in several stages, somewhat haphazardly. Parts II and III are probably the oldest parts. The final stage in the composition of the book is probably the addition of part VII. Part II belongs in the same liturgical tradition as C.ö.IV.7 (Oripään Missale I), probably that of Diocese of Linköping. Part III, a votive missal, is an informal copy of a book that would most probably have been used close to a Swedish cathedral (Linköping?). How the present book found its way to Oripää chapel is not known.

Role of service and data reuse in enterprises

Digitalization has been predicted to change the future as a growing range of non-routine tasks will be automated, offering new kinds of business models for enterprises. Serviceoriented architecture (SOA) provides a basis for designing and implementing welldefined problems as reusable services, allowing computers to execute them. Serviceoriented design has potential to act as a mediator between IT and human resources, but enterprises struggle with their SOA adoption and lack a linkage between the benefits and costs of services. This thesis studies the phenomenon of service reuse in enterprises, proposing an ontology to link different kinds of services with their role conceptually as a part of the business model. The proposed ontology has been created on the basis of qualitative research conducted in three large enterprises. Service reuse has two roles in enterprises: it enables automated data sharing among human and IT resources, and it may provide cost savings in service development and operations. From a technical viewpoint, the ability to define a business problem as a service is one of the key enablers for achieving service reuse. The research proposes two service identification methods, first to identify prospective services in the existing documentation of the enterprise and secondly to model the services from a functional viewpoint, supporting service identification sessions with business stakeholders.
