PurposeThe aim of the research is to determine the influence of photovoltaic (PV) installation and the share of façade glazing on the energy profile of nursery buildings in the Baltic Sea region, as well as defining the most favorable configuration in terms of energy efficiency.Design/methodology/approachThe article provides comparative calculations of energy performance indicators (Ep, Ed, Eu) and CO2 emissions (mCO2) made for the defined model of the nursery. It includes calculations concerning energy performance of the building, depending on its PV power (0–60 kWp), PV efficiency (100 and 85%) and façade glazing ratio (GR = 25%, 50% and 75%).FindingsThe results of the research indicate that an increase in the PV power exerts proportional impact on the reduction of the Ep and Ed indicators, as well as on the CO2 emissions. Only low GR values (25%) reduce the Eu indicator significantly. Decrease in high range of GR values (over 50%) does not provide proportional effects. In the variant: 60 kWp (100% efficiency) with GR = 25%, the biggest share (99.5%) of RES was obtained. This proves that the concept of energy independent nursery buildings is feasible and reasonable in the examined location.Practical implicationsDesigning buildings towards environmental neutrality requires laborious pre-design conceptual work before developing the right solutions. The set of results of the relationship between the variables of the building's envelope, energy performance indicators and the required involvement of active RES installations to achieve high energy performance of a building presented in the article is valuable. It allows for a preliminary decision of the direction of the design solutions selection in the design process of public utility buildings, such as nurseries. Thus, it may significantly shorten the pre-design analysis process for the location of the southern part of the Baltic Sea region.Originality/valueThe novelty of the paper relies on examining the dependences between PV power and façade glazing ratio in terms of their influence on energy profile of nursery buildings.

Purpose – Purpose of this research is to shed light on the changes caused by shipping sulphur regulation, which will globally take off during years 2015 and 2020. It has significant effects on diesel markets globally, but especially in regions, where demanding 0.1 per cent level is required. One of these regions is the Baltic Sea. It is relatively undealt issue, how this forthcoming change will affect these specific sub-regions of stiff 0.1 per cent sulphur level demand and their transportation modes with different tax obligations. Design/methodology/approach – The authors use second-hand data from various different sources, earlier research as well as simulation to estimate the effects on the diesel markets and transportation prices in the Baltic Sea region. Different transportation modes have diverging taxation treatment on diesel oil use, which complicates analysis further. Findings – Based on research findings, it is rather probable that diesel markets for sulphur-free diesel oil shall face price spike in the beginning of 2015 in the Baltic Sea region. This is mostly explained with needed large-scale scrubber investment and short-time span to complete these (there are both technical and financial challenges). Therefore, numerous ships shall enter sulphur-free diesel oil market. Based on the simulation study, freight transportation will mostly be hurt in shipping, whereas road and rail shall face smaller price increases. Results are mostly explained with taxation treatment, where shipping is still using tax-free diesel oil, and no fixed taxes are hedging this transportation mode from sudden price changes. Research limitations/implications – Analysis concerns only Baltic Sea region, and effects and changes in the entire Europe from sulphur regulation change in 2015 are unknown. This would mean to extent study to North Sea. In addition, taxation system harmonization is not yet complete in Europe, and differences exist between member states. Research work was completed with diesel oil tax treatment regarding different transportation modes in Finland. Practical implications – Based on this study, short sea shipping will be hurt by regulation change in 2015. However, in the future, this transportation mode shall face additional cost increases, as most probably, tax harmonization in diesel markets shall lead to fixed taxes added on shipping diesel. So, transportation mode shall face difficult and challenging times ahead. Originality/value – Research is seminal study from possible sulphur regulation change implications in transportation mode level. It takes into account taxation treatment, cost share of diesel in transportation mode level and possible diesel price change. Until today, no other study exists in this detailed level.

ABSTRACTThe genetic diversity ofVibrio vulnificusisolates from clinical and environmental sources originating from the Baltic Sea region was evaluated by multilocus sequence typing (MLST), and possible relationships between MLST clusters, potential genotypic and phenotypic traits associated with pathogenicity, and source of isolation were investigated. The studied traits included genotyping of polymorphic loci (16S rRNA,vcg, andpilF), presence/absence of potential virulence genes, includingnanA,nab, and genes of pathogenicity regions, metabolic features, hemolytic activity, resistance to human serum, and cytotoxicity to human intestinal cells. MLST generated 35 (27 new) sequence types and divided the 53 isolates (including four reference strains) into two main clusters, with cluster I containing biotype 1 and 2 isolates of mainly environmental origin and cluster II containing biotype 1 isolates of mainly clinical origin. Cluster II isolates were further subdivided into two branches. Branch IIB included isolates from recent cases of wound infections that were acquired at the German Baltic Sea coastline between 2010 and 2011 and isolates from seawater samples of the same regions isolated between 1994 and 2010. Comparing the MLST data with the results of genotyping and phenotyping showed that strains of MLST cluster II possess a number of additional pathogenicity-associated traits compared to cluster I strains. Rapid microbiological methods such as matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) mass spectrometry combined with typing of selected virulence-associated traits (e.g., serum resistance, mannitol fermentation,nanA, and pathogenicity region XII) could be used for risk assessment purposes regardingV. vulnificusstrains isolated from the Baltic Sea region.

Purpose – The purpose of this paper is to advance a new way of explaining and tackling the illegitimate wage practice where employers pay their employees an undeclared (envelope) wage in addition to their formal salary. Drawing upon institutional theory, it is here proposed that envelope wages result from the lack of alignment of a society’s formal institutions (i.e. the codified laws and regulations) with its informal institutions (i.e. the socially shared unwritten understandings which reflect citizens’ norms, values and beliefs). Design/methodology/approach – To evaluate this, data are reported from a 2013 Eurobarometer survey involving 1,738 face-to-face interviews with formal employees in four Baltic countries, namely, Estonia, Latvia, Lithuania and Poland. Findings – The finding is that the greater is the asymmetry between the formal and informal institutions (i.e. the level of disagreement of citizens with the codified laws and regulations of formal institutions), the higher is the propensity to pay envelope wages. This is the case at both the individual- and country levels. Practical implications – To reduce the prevalence of envelope wages, the resultant argument is that the values of employers and employees need to be aligned with the formal institutions. This requires alterations not only in the informal institutions, using measures such as tax education, awareness raising campaigns and normative appeals, but also changes in formal institutions so as to improve trust in government by fostering greater procedural justice, procedural fairness and redistributive justice. Originality/value – This is the first paper to apply institutional theory to explaining and tackling envelope wages in the Baltic Sea region.

AbstractGeological investigations of a part of the crystalline basement in the Baltic Sea have been performed on a drill core collected from the depth of 1092–1093 m beneath the Phanerozoic sedimentary cover offshore the Latvian/Lithuanian border. The sample was analyzed for geochemistry and dated with the SIMS U–Pb zircon method. Inherited zircon cores from this migmatized granodioritic orthogneiss have an age of 1854 ± 15 Ma. Its chemical composition and age are correlated with the oldest generation of granitoids of the Transscandinavian Igneous Belt (TIB), which occur along the southwestern margin of the Svecofennian Domain in the Fennoscandian Shield and beneath the Phanerozoic sedimentary cover on southern Gotland and in northwestern Lithuania. It is suggested that the southwestern border of the Svecofennian Domain is located at a short distance to the SW of the investigated drill site. The majority of the zircon population shows that migmatization occurred at 1812 ± 5 Ma, with possible evidence of disturbance during the Sveconorwegian orogeny.

AbstractThe increased demand for wood to replace oil-based products with renewable products has lifted focus to the Baltic Sea region where the environment is favorable for woody biomass growth. The aim of this study was to estimate broad-sense heritabilities and genotype-by-environment (G×E) interactions in growth and phenology traits in six climatically different regions in Sweden and the Baltics. We tested the hypothesis that both bud burst and bud set have a significant effect on the early growth of selected poplar clones in Northern Europe. Provenance hybrids of Populus trichocarpa adapted to the Northern European climate were compared to reference clones with adaptation to the Central European climate. The volume index of stemwood was under low to medium genetic control with heritabilities from 0.22 to 0.75. Heritabilities for phenology traits varied between 0.31 and 0.91. Locally chosen elite clones were identified. G×E interactions were analyzed using pairwise comparisons of the trials. Three different breeding zones for poplars between the latitudes of 55° N and 60° N in the Baltic Sea Region were outlined. The studied provenance hybrids with origin from North America offer a great possibility to broaden the area with commercial poplar plantations in Northern Europe and further improve the collection of commercial clones to match local climates. We conclude that phenology is an important selection criterion after growth.

Abstract In the future, health promotion would require developed strategies that lead to stronger cross-sectoral cooperation. Cross-sectoral cooperation enables the integration of fragmented resources and competencies, which benefit service solutions for urban health. Healthy Boost “Urban Labs for Better Health for All in the Baltic Sea Region”, funded by the EU Interreg Baltic Sea Region -program, aims to develop the Model for cross-sectoral cooperation, which will be tested in the cities of the Baltic Sea Region during 2020-21. The self-assessment tool for cross-sectoral cooperation was developed, and the self-assessment among the nine cities in seven countries from the Baltic Sea Region was conducted in 2019. The results indicated to what extent the staff (n = 329) in the cities have recognized the cross-sectoral cooperation for health and wellbeing as strategically crucial in their policies, communication, and in the design of their organizational functions. The daily practices were evaluated in terms of how systematically cities have implemented cross-sector actions for health and wellbeing. The biggest challenges for cooperating across sectors for the cities were coordination and systematic identification of the community needs for health promotion. The cooperative actions were less systematic than expected in the strategic approach. The variation among respondents' assessments was high within the cities that lead to a conclusion about existing gaps in coordination, communication, and leadership of cross-sectoral work within the cities. The Likert type self-assessment measurement was statistically reliable in both strategic and operational dimensions of cooperation. Key messages Evaluation and measurements are needed to identify cross-sectoral actions to health and well-being. The evidence-based Model developed in the Healthy Boost project will guide partners towards systematic cross-sectoral cooperation processes.
