    Consumer acceptance of new bio-based products plays a key role in the envisioned transition towards a forest-based bioeconomy. Multi-storey wooden buildings (MSWB) exemplify a modern, bio-based business opportunity for enacting low-carbon urban housing. However, there is limited knowledge about the differing perceptions consumers hold regarding wood as an urban building material. To fill this gap, this study explores Finnish students' perceptions of MSWB relative to their familiarity with wooden residential buildings, and then connects these perceptions to 'consumption styles.' Data were collected in the Helsinki metropolitan area via an online questionnaire (n = 531). The results indicate that the aesthetic appearance of MSWB are appreciated most by frugal and responsible consumers, whereas the comfort, environmental friendliness, and longevity of MSWB are important to consumers who identify themselves as 'thoughtful spenders.' The study suggests that both environmental and hedonic young consumers already familiar with the use of wood in housing contribute to a successful bioeconomy in the urban context.

    This review article examines how social science literature co-produces various imaginaries of forest-based bioeconomy transformations and pathways for reaching desired ends. Based on an analysis of 59 research articles, we find that despite a growing number of social sciences studies on the forest-based bioeconomy, much of the research tends to replicate a bioeconomy imaginary articulated in EU and national bioeconomy policies and strategies. Accordingly, the research primarily reproduces a weak approach to sustainability, which prioritize economic growth and competitiveness. Expectations are largely directed at national and regional corporate interests and forest industrial renewal, while the state has a supportive rather than restricting role. We discuss the findings against the role of social sciences, and conclude that social science scholars may adopt various strategies if interested in opening up forest-based policy debates and offer alternative imaginaries of sustainable bioeconomy transformations.

    Arctic sea ice concentration (SIC) has been studied extensively using passive microwave (PM) remote sensing. This technology could be used to improve navigation along vessel cruise paths; however, investigations on this topic have been limited. In this study, shipborne photographic observation (P-OBS) of sea ice was conducted using oblique-oriented cameras during the Chinese National Arctic Research Expedition in the summer of 2016. SIC and the areal fractions of open water, melt ponds, and sea ice (A(w), A(p), and A(i), respectively) were determined along the cruise path. The distribution of SIC along the cruise path was U-shaped, and open water accounted for a large proportion of the path. The SIC derived from the commonly used PM algorithms was compared with the moving average (MA) P-OBS SIC, including Bootstrap and NASA Team (NT) algorithms based on Special Sensor Microwave Imager/Sounder (SSMIS) data; and ARTIST sea ice, Bootstrap, Sea Ice Climate Change Initiative, and NASA Team 2 (NT2) algorithms based on Advanced Microwave Scanning Radiometer 2 (AMSR2) data. P-OBS performed better than PM remote sensing at detecting low SIC (<10%). Our results indicate that PM SIC overestimates MA P-OBS SIC at low SIC, but underestimates it when SIC exceeds a turnover point (TP). The presence of melt ponds affected the accuracy of the PM SIC; the PM SIC shifted from an overestimate to an underestimate with increasing A(p), compared with MA P-OBS SIC below the TP, while the underestimation increased above the TP. The PM algorithms were then ranked; SSMIS-NT and AMSR2-NT2 are the best and worst choices for Arctic navigation, respectively.

    So far, consumer housing values have not been addressed as factors affecting the market diffusion potential of multi-storey wood building (MSWB). To fill the void, this study addresses different types of consumer housing values in Denmark, Finland, Norway, and Sweden (i.e., Nordic region), and whether they affect the likelihood of prejudices against building with wood in the housing markets. The data collected in 2018 from 2191 consumers in the Nordic region were analyzed with exploratory factor analysis and logistic binary regression analysis. According to the results, consumers' perceptions on ecological sustainability, material usage and urban lifestyle were similar in all countries, while country-specific differences were detected for perceptions on aesthetics and natural milieus. In all countries, appreciating urban lifestyle and living in attractive neighborhoods with good reputation increased the likelihood of prejudices against wood building, while appreciation of aesthetics and natural milieus decreased the likelihood of prejudices. In strengthening the demand for MSWB and sustainable urbanization through actions in businesses (e.g., branding) and via public policy support (e.g., land zoning), few messages derive from the results. In all, abreast with the already existing knowledge on the supply side factors (e.g., wood building innovations), more customized information is needed on the consumer-driven issues affecting the demand potential of MSWB in the housing markets. This would enable, e.g., both enhancing the supply of wooden homes for consumers appreciating urban lifestyle and neighborhoods and fortifying positive image of wood among consumers especially appreciating good architecture and pleasant environmental milieus.

    This study identifies new wood-based products with considerable potential and attractive markets, including textiles, liquid biofuels, platform chemicals, plastics, and packaging. We apply a mixed-methods review to examine how the position of the forest industry in a given value chain determines the respective production value. An assessment is provided as to the degree to which these emerging wood-based products could compensate for the foreseen decline of graphic paper markets in four major forest industry countries: USA, Canada, Sweden, and Finland. A 1%-2% market share in selected global markets implies a potential increase in revenues of 18-75 billion euros per annum in the four selected countries by 2030. This corresponds to 10%-43% of the production value of forest industries in 2016 and compares with a projected decline of graphic paper industry revenue of 5.5 billion euros by 2030. The respective impacts on wood use are manifold, as many of the new products utilize by-products as feedstock. The increase in primary wood use, which is almost entirely attributed to construction and to some extent textiles markets, would be in the range of 15-133 million m(3), corresponding to 2%-21% of the current industrial roundwood use in the selected countries.

    A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at root s = 13 TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lljj final state with l including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The measured cross section in a kinematic region defined by invariant masses m(ll) > 50 GeV, m(jj) > 120 GeV, and transverse momenta P-Tj > 25 GeV is sigma(EW) (lljj) = 534 +/- 20 (stat) fb (syst) fb, in agreement with leading-order standard model predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. No evidence is found and limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are -2.6 <cwww/Lambda(2) <2.6 TeV-2 and -8.4 <cw/Lambda(2) <10.1 TeV-2. The additional jet activity of events in a signal-enriched region is also studied, and the measurements are in agreement with predictions.

    The transformation of the forest sector toward a bioeconomy calls for finding new sources of competitive advantage for the whole sector to retain its future viability. Non-industrial private forest owners are an important group of actors in the Finnish forest-based sector, as they supply 80% of industrial roundwood and control numerous other tangible and intangible forest-based ecosystem services. Our study analyzes forest owner views on the future use of forests in Finland, their perceptions on the evolving sectorial interlinkages and the position of the forest sector now and in the future bioeconomy. The data were collected in two phases: through telephone interviews of forest owners (n=278) and four focus group (FG) discussions (n=17), and were analyzed both qualitatively and quantitatively. The interviews showed that forest owners consider the highest potential for strengthening the sector toward bioeconomy to come from collaboration with energy and construction businesses. During the FG phase, we identified new possibilities founded on forest-based recreational services, cooperation with nature-based tourism and in increasing value-added wood products. In total, forest owners as a high-involvement group emphasized future value creation to be based upon forest ecosystem services and in diversifying the utilization of forests beyond the dominant raw material-driven mindset.

    With the international community's increasing concern for social and environmental problems, the fulfilment and disclosure of corporate social responsibility (CSR) has been advocated and promoted across the world. Forestry companies, which are particularly sensitive to environmental and social issues, are increasingly developing and improving their levels of CSR disclosure. However, information on emerging country contexts is still lacking. To fill this gap, this study focuses on Chinese forestry companies' CSR disclosure and introduces new disclosure indices through content analysis of annual reports by listed companies between 2011 and 2015. It then builds a correlation analysis of the factors influencing these companies' disclosure indices in order to gain a better understanding of the current situation for CSR implementation by forestry companies in emerging economies like China. Although context-specific, our findings can provide a reference for researchers and policy makers, and promote sustainable development via improved CSR disclosure by forestry companies, especially in developing regions.

    As wine supply chains become increasingly globalized, sustainability issues take on ever greater importance. This is the first study to analyse the environmental sustainability aspect of greenhouse gas (GHG) emissions from a global wine supply chain perspective, covering just over 90% of Finland's wine imports. Lacking substantial domestic production capacity, virtually all wine consumed in Finland is imported. Finland is comparable to its Nordic neighbours, Sweden and Norway, in this respect. The Life Cycle Assessment (LCA) methodology was combined with sensitivity and scenario analyses to investigate GHG emissions implications from prospective policy changes. Our results spotlight differences related to wine production in the eight main wine producing countries for the Finnish market (Australia, Chile, France, Germany, Italy, Spain, South Africa, and the United States), related logistics, and all packaging types for wine used in Finland (glass bottle, Bag-in-Box, PET bottle, beverage carton, and pouch). We found an average value of 1.23 kg CO2e for 0.75 L wine consumed in Finland, ranging from 0.59 kg CO2e for French wine in a bag-in-box packaging to 1.92 kg CO2e for Australian wine in a glass bottle. After identifying the main GHG emission hotspots in the wine supply chain, our scenario analyses highlight the effects of reducing glass bottle weight, moving away from glass packaging toward bag-inbox, increasing bulk wine export volumes to Finland, and following the European Commission's Energy 2020 strategy which targets increasing energy efficiency by 20 percent.

    The aim of this explorative study is to find out how the EU Timber Regulation (EUTR) has affected the forest and chain of custody (CoC) certification strategies and practices among the Finnish wood industry companies. We are especially interested to find out whether more integrated strategies and collaborative networks have emerged for enhanced communications throughout the industry value chains. This qualitative interview study included both EUTR ex ante and ex post analysis, based on three rounds of managerial and expert interviews during 2011-2015. The results indicate that the EUTR appears to have enforced the supplier-client relations in the Finnish wood industry value chain. The sector still lacks integrated communication strategies with better understanding of customer and stakeholder values, which could contribute to more cohesive communication and marketing efforts reflecting the values of the whole industry. The certification practices are fairly spontaneously implemented following the traditional industry culture, which is not supportive of innovations and gaining competitive advantages in the broader material markets. Furthermore, the existence of two parallel forest certificates (Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC)) seems to hamper the effective communication and building of an image of sustainable wood products among customers and end consumers, groups that are also exposed to more general environmental communication, e.g., in the building material markets.

    With the development of ecological paradigm coupled with the relentless implementation of myriad environmental policies in China, the rapid development of carbon emission trading and carbon trading market has had a vital impact on the financial performance of enterprises at the microlevel. This study has sampled the A-share listed companies in China, from 2009 to 2018, and adopted the difference-in-difference (DID) method to investigate the effect of the carbon emission trading on corporate financial performance from the microlevel. Evidence showed that the implementation of carbon emission trading effectively improved the total asset-liability ratio of enterprises, though it reduced the value of the current capital market. Moreover, in the regions under strict legal environment, the enhancement effect of the total asset-liability ratio was more obvious, whereas in the regions under loose legal environment, the reduction effect of the value of the capital market was more obvious. Further analysis showed that the implementation of carbon emission trading could not promote Chinese enterprises to increase R&D investment. Hence the implementation of carbon emission trading has improved the level of non-business income of enterprises incorporated into the trading system, but its impact on the investment income of enterprises was not significant.

    Intermediaries can potentially help reduce institutional lock-ins that slow down sustainability transitions by influencing policy processes, because of their connectedness and often high level of legitimacy. In this paper, we analysed intermediaries seeking to accelerate the diffusion of wooden multi-storey construction (WMC) in Finland, their roles and engagement in policy processes. Increasing the use of wood in construction has high policy support nationally, backed up with climate and forest policies. Yet, market diffusion has been slow. The data consist of qualitative interviews of intermediaries and other actors, participatory observation and a review of secondary materials. The results reveal a complex set of intermediaries, including systemic, niche and regime-based ones. The intermediaries are characterised by multiple goals, partly overlapping roles and means of policy influencing. The low degree of coordination among the intermediaries and the differences in their agenda for transition are critical challenges which limit the effectiveness of their actions.

    Making use of a dimensionally-reduced effective theory at high temperature, we perform a nonperturbative study of the electroweak phase transition in the Two Higgs Doublet model. We focus on two phenomenologically allowed points in the parameter space, carrying out dynamical lattice simulations to determine the equilibrium properties of the transition. We discuss the shortcomings of conventional perturbative approaches based on the resummed effective potential — regarding the insufficient handling of infrared resummation but also the need to account for corrections beyond 1-loop order in the presence of large scalar couplings — and demonstrate that greater accuracy can be achieved with perturbative methods within the effective theory. We find that in the presence of very large scalar couplings, strong phase transitions cannot be reliably studied with any of the methods.

    Objectives This study aimed to develop and validate a risk prediction model for long-term sickness absence. Methods Survey responses on work-and lifestyle-related questions from 65 775 public-sector employees were linked to sickness absence records to develop a prediction score for medically-certified sickness absence lasting > 9 days and >= 90 days. The score was externally validated using data from an independent population-based cohort of 13 527 employees. For both sickness absence outcomes, a full model including 46 candidate predictors was reduced to a parsimonious model using least-absolute-shrinkage-and-selection-operator (LASSO) regression. Predictive performance of the model was evaluated using C-index and calibration plots. Results Variance explained in >= 90-day sickness absence by the full model was 12.5%. In the parsimonious model, the predictors included self-rated health (linear and quadratic term), depression, sex, age (linear and quadratic), socioeconomic position, previous sickness absences, number of chronic diseases, smoking, shift work, working night shift, and quadratic terms for body mass index and Jenkins sleep scale. The discriminative ability of the score was good (C-index 0.74 in internal and 0.73 in external validation). Calibration plots confirmed high correspondence between the predicted and observed risk. In > 9-day sickness absence, the full model explained 15.2% of the variance explained, but the C-index of the parsimonious model was poor ( Conclusions Individuals' risk of a long-term sickness absence that lasts >= 90 days can be estimated using a brief risk score. The predictive performance of this score is comparable to those for established multifactorial risk algorithms for cardiovascular disease, such as the Framingham risk score.

    We consider the Higgs-radion mixing in the context of warped space extradimensional models with custodial symmetry and investigate the prospects of detecting the mixed radion. Custodial symmetries allow the Kaluza-Klein excitations to be lighter and protect Zbb to be in agreement with experimental constraints. We perform a complementary study of discovery reaches of the Higgs-radion mixed state at the 13 and 14 TeV LHC and at the 500 and 1000 GeV International Linear Collider (ILC). We carry out a comprehensive analysis of the most significant production and decay modes of the mixed radion in the 80 GeV-1 TeV mass range and indicate the parameter space that can be probed at the LHC and the ILC. There exists a region of the parameter space which can be probed, at the LHC, through the diphoton channel even for a relatively low luminosity of 50 fb(-1). The reach of the four-lepton final state in probing the parameter space is also studied in the context of 14 TeV LHC, for a luminosity of 1000 fb(-1). At the ILC, with an integrated luminosity of 500 fb(-1), we analyze the Z-radion associated production and the WW fusion production, followed by the radion decay into b (b) over bar and W+W-. The WW fusion production is favored over the Z-radion associated channel in probing regions of the parameter space beyond the LHC reach. The complementary study at the LHC and the ILC is useful both for the discovery of the radion and the understanding of its mixing sector.

    Climate change has recently been a subject of increased attention in the shipping sector. Along with technical issues of GHG emissions reduction, a question of appropriate governance has been raised. The argument regarding the role of global, regional, and local policies in curbing shipping emissions is a part of a broader theoretical debate on forms of global governance. This paper examines the recent literature on polycentric climate governance and suggests principles for environmental regulation in shipping based on a polycentric approach.

    The models based on SU(3)C x SU(3)L x U(1)X gauge symmetry (331-models) have been advocated to explain the number of fermion families. These models place one quark family to a different representation than the other two. The traditional 331-models are plagued by scalar mediated quark flavour changing neutral currents (FCNC) at tree- level. So far there has been no concrete mechanisms to suppress these FCNCs in 331- models. Recently it has been shown that the Froggatt-Nielsen mechanism can be incorporated into the 331-setting in an economical fashion (FN331-model). The FN331-model explains both the number of fermion families in nature and their mass hierarchy simultaneously. In this work we study the Higgs mediated quark FCNCs in FN331-model. The flavour violating couplings of quarks are suppressed by the ratio of the SU(2)L x U(1)Y and SU(3)L x U(1)X breaking scales. We find that the SU(3)L x U(1)X -breaking scale can be as low as 5 TeV in order to pass the flavour bounds.

    The rise of wooden multistory construction (WMC) in the Nordic countries has turned out to be the most evident construction-related new business opportunity in the emerging bioeconomy. Based on earlier literature, the future growth prospects for the rise of WMC are rooted in the concerns regarding environmental issues, as witnessed in a plethora of studies focusing on carbon footprinting. But do new (performance-based) regulations ‘favor’ WMC or do they give a more ‘just’ comparison of alternative building concepts? Therefore, more information is needed on the role of growing environmental awareness and preferences for wood as a renewable and recyclable material in the markets. Our paper presents results from a two-round Delphi study focusing on the relative strength and perceived interplay between likelihood and the desirability of environmental concerns in driving WMC in Finland and Sweden. Using qualitative analysis of expert interviews in the first Delphi round, the issues related to sustainable development appear to have growing importance in the marketplace. However, the panelists perceive that the emphasis on sustainability is mainly driven by the changing regulation reflecting societal needs, and only few experts saw it as echoing directly from changing individual consumer needs. In the second Delphi round, implemented with an online survey, the likelihood and desirability of sustainability as a megatrend in housing was perceived to gain further impetus toward 2030, both in the form of consumer demand for sustainable living and wood construction as a modern way of living. However, future research is needed to get a better understanding on the strength and scope of these drivers.

    We calculate the vacuum stability conditions and renormalisation group equations for the extensions of standard model with a higher colour multiplet scalar up to the representation 1 5 0 that leaves the strong interaction asymptotically free. In order to find the vacuum stability conditions, we calculate the orbit spaces for the self-couplings of the higher multiplets, which for the representations 1 5 and 1 5 0 of SU(3)(c) are highly complicated. However, if the scalar potential is linear in orbit space variables, it is sufficient to know the convex hull of the orbit space. Knowledge of the orbit spaces also facilitates the minimisation of the potentials. In contrast to the self-couplings of other multiplets, we find that the scalar quartic couplings of the representations 3 and 8 walk rather than run, remaining nearly constant and perturbative over a vast energy range. We describe the conditions for walking couplings using a schematic model. With these technical results at hand we revise earlier results of generation of new scales with large SU(3) c scalar multiplets. Our results are easily extendable to models of new physics with additional SU(3) or SU(N) gauge symmetries.
