Are sustainable fashion SMEs ready for circularity? The current state and vision of sustainable SMEs in the fashion system

The fashion industry is a significant contributor to global environmental and social issues. But as a system, it is composed of different stakeholders that can work together to make a change. One of those actors involved are small fashion labels, which according to the European Commission, account for more than 90% of the workforce and produce almost 60% of the value within the textile industry (2017). Small firms cannot be treated just as smaller versions of their larger counterparts. Thus, tailored policies addressing their specific needs and the specific sector in which they operate, should be implemented in order to facilitate their shift towards more sustainable and circular business models. The aim of this thesis is to improve our understanding on issues related to the current and potential practices of small enterprises to close their material loop. Through the analysis of 60 websites, which sustainable design strategies SMEs are implementing in the EU-28 are investigated. The results showed that nowadays sustainable labels are still focusing on eco- efficient principles, mainly materials selection, and are not considering all the phases of the lifecycle of their products. In accordance with this finding, the coding of 18 interviews with European-based brands revealed that the main challenges that these enterprises face when implementing sustainability innovation, are related to availability of sustainable materials, high minimum orders quantities, commercial relationships with suppliers, and consumers yet not properly-aware. Moreover, due to the industry in which they operate, when adopting green practices, they cannot compromise on style or aesthetic qualities of their products. Whereas the main driver mentioned by all the interviewees seem to be personal commitment. Moreover, because the current discussion in Europe focuses on circular economy, it is essential to investigate the perception of sustainable labels on this topic, because it should not be taken for granted that they will automatically move towards circularity. Indeed, this research revealed that they perceive circularity as a concept not yet applicable for their businesses, and this is justifiable by the fact that currently there is not a circular fashion system in place and recycling technologies are not industrially developed yet.
THE RELATIONSHIP BETWEEN TOURIST ARRIVALS AND ACCOMODATION IN ROMANIAN REGIONS. A PANEL DATA APPROACH

This research is a novelty for the literature regarding tourism demand modeling in Romania. Panel data approach has been applied to analyze the relationship between tourist arrivals and the establishments of tourists ’ reception with functions of tourists ' accommodation in the eight Romanian regions ( Nord-West region, Central region, Nord-East region, South-East region, South-Muntenia region, Bucharest-Ilfov region, South-West Oltenia and West regions ). According to panel VAR Granger causality test, the establishments of tourists ’ reception with functions of tourists ' accommodation are a cause for tourist arrivals, but the relationship is not reciprocal. A valid fixed effects model was built and an increase in the number of establishments of tourists ’ reception with functions of tourists ' accommodation with one establishment increased in average the number of tourist arrivals with around 293 people in Romanian regions over the period 1990-2015. According to panel vector-autoregressive model, the tourist arrivals in the current period were positively influenced by the establishments of tourists ’ reception with functions of tourists ' accommodation and tourist arrivals in the previous period.
Fake real quadratic orders

The study of fake real quadratic orders is fascinating as their class group structure is similiar to real quadratic fields. Statistical data strongly agree with the heuristics of Cohen and Lenstra of real quadratics with class number one. We will investigate why this holds true as well as explore other analogues to open conjecture on real quadratic fields, such as the Ankeny-Artin-Chowla Conjecture, and present various results that mark the similiarities between real quadratic fields and fake real quadratic orders. Fake real quadratics are defined by inverting an ideal above any prime p which is split in OK where K = Q( √ D) is an imaginary quadratic field.
Analysis and Calculation of Odd Cycle Centrality Aimed for Vertex-Cover

We propose a kind of centrality, the odd cycle centrality which has strong relationship with solving minimum vertex-cover. The formal definition of the odd cycle centrality with its comparison to other centralities is given. Besides, as a variant of MAX-2-XORSAT, it is analyzed in the viewpoint of solving linear equations set. To calculate this centrality and view its effect on different graph structures, a random-walk based method is built to realize the centrality of each node on random graphs and scale-free networks. Using the importance order such as centrality provides one way to understand the topological structure or functions of a network, and it also offers a new viewpoint to solve the constraint satisfaction problems and recognize their complexity. Keywords—centrality; minimum vertex cover; MAX-2XORSAT; random walk
modelling in the absence of supporting electrolyte : coping with migration and changing resistance in predicting v oltammetry

Convolutive modelling is a rigorous alternative to digital simulation for predicting the outcome of voltammetric experiments. The potentiality of this approach is here extended to embrace situations of low electrolyte concentration, in which both migration and changing uncompensated resistance cause complications. Two and three-electrode cells are considered and examples of chronopotentiometry and cyclic voltammetry are examined in detail. # 2002 Elsevier Science B.V. All rights reserved.
Digitalization of Physical Content Products-an Investigation into Consumer Perceived Value

The significance of consumer perceived value for marketing decisions and the link between value creation and business long-term success is widely acknowledged in the literature. However, no study has yet assessed empirically if different perception of value exist for physical products compared to their digital counterparts. A perceived value model consisting of five constructs –price value, quality value, epistemic value, emotional value and social value, is applied. Further, a digital basic version is tested against an ownership-enhanced digital version and one where the perceived effort to gain and handle the digital version is reduced. A significant increase for digital products by improving the ownership notion or reducing the perceived effort was not to be found. Nevertheless, tendencies support the general idea and prepare the ground for further investigations. This thesis progresses the value literature through increasing our comprehension of how individual value dimensions differ for physical and digital products. Based on the primary data gathered by a customer survey, the findings support that different perceptions of value exist for physical products compared to their digital counterparts, particularly for epistemic, emotional and quality value. This calls for the use of differentiated value-based marketing strategies for a company to be successful in both, the real and the digital world.
The Effect of microwave frequency on dielectric properties and Pyrolysis of oil shales

In the present work, the effect of in situ electromagnetic retorting technologies on the oil shales was reviewed. In this literature review on oil shales dielectric properties, we found that the relative dielectric constant (e′) and imaginary permittivity (e″) decrease with increased frequency and remain constant at higher frequencies. Formation fluids and mineral-bound water also affect measured dielectric properties. This review presents and synthesizes prior work on the influence of applied frequency on the dielectric properties of oil shales that can aid in the future development of frequency specific in situ retorting technologies and oil shale grade assay tools. The results obtained revealed that this process can be efficiently used for the purpose. The oil shale seems related to the retorting of the shale and the products of the degradation of the kerogen. In addition, the obtained oil has interesting characteristics. It is more maltenic, less polar than the oils obtained by conventional pyrolysis.
Delivery Long-Term Care Support Services and Care Recipients' Health Outcomes: Synthesis of Current Evidence

The combined impacts of population aging and longer life expectancies contribute to a surge in the number of older adults with physical and cognitive impairment. More than 12 million people (about 6.7 million are elderly aged over 65 years) in the U.S. need long-term care services and supports (LTSS) and this number is projected to be over 27 million by 2050. LTSS refers to a broad range of services to provide assistance over prolonged period of time due to physical or mental disability. People generally receive LTSS in a variety of settings- informally from friends and family or formal home and community based care or institutional care (such as nursing home). A major challenge facing the country is how best to meet the growing needs for LTSS in most homelike- setting and least institutional setting and to achieve best possible health outcomes. To address this challenge the evaluation of relative effectiveness of the use of informal and formal LTSS on care recipients’ physical, emotional and mental health outcomes is imperative. The goals of this brief review are 1) to investigate existing evidence on the benefits of the use of informal and formal LTSS on the older adults’ physical and mental health outcomes and 2) potential areas for future research on empirical evidence of the effectiveness of the use of informal and formal LTSS influencing care recipients’ health outcomes.
Elastic properties of elemental, binary and ternary semiconductor materials

Elastic properties of elemental (C, Si, Ge), binary (II-VI, III-V) and ternary (I-III-VI 2 , II-IV-V 2 ) semiconductors have been studied. New relations, based on plasma oscillation theory of solids, have been proposed for the calculation of bulk modulus ( B ), microhardness ( H ) and shear modulus ( G ) of these materials. The values of B, H, G and G / B ratio have been calculated for 13 new compounds of II-IV-V 2 family. The calculated values are compared with the available experimental and reported values. Reasonably good agreement has been obtained between them. The average percentage deviation of proposed relations has also been estimated and found to be better than earlier correlations.
Comparison of RAPD and PCR-RFLP markers for classification and taxonomic studies of insects

Experiments were conducted to assess the efficiency of RAPD and PCR-RFLP marker systems as molecular tools for taxonomy and classification of insects. Three species of adult ants, Camponotus maculatus, Monomorium pharoensis and Cataglyphis bicolor, were used in this study. Total genomic DNA was extracted and used for PCR amplification of the ITS region. The purified PCR products were subjected to single digestion with EcoRI, MspI, TaqI and SacI enzymes and visualized on 2% agarose gel. In addition, 40 arbitrary primers were used to generate RAPDPCR profiles. Data obtained from RFLP, RAPD and RFLP+RAPD were statistically and phylogenetically analyzed to determine the level of polymorphism in each case. Intraspecific, interspecific variation levels and phylogenetic relationships were investigated. Results were discussed, comparatively, and the final conclusion was: on the bases of ease, cost, technical labor, speed and amount of DNA needed, the RAPD marker system is preferentially used in taxonomic and classification studies. On the bases of degree of polymorphism, precision of genetic distance estimates and the statistical power of the test, no differences were observed between RAPD and PCRRFLP tests.
The role of fungal taxa and developmental stage of mushrooms in determining the composition of the mycophagous insect community in a Japanese forest

We hypothesize that differences in fungal taxonomic groups may exert a direct influence on the composition of myco- phagous insect communities, and that the relative importance of taxonomy compared to other fungal traits may change as the mush- rooms decay. We conducted a 3-year field survey and analyzed the species composition of mycophagous insect communities using partial canonical correspondence analysis (partial CCA). We collected 2457 mushrooms belonging to 27 genera, and 4616 insects belonging to 16 families emerged from 439 of the mushrooms. For the whole insect community, fungal genera explained 10-19% of the total variance in the family composition of the insect communities of mushrooms at different developmental stages. Only the fungal genus Collybia significantly affected the community composition almost irrespective of developmental stage. In the droso- philid community, which consisted of 844 individuals from 9 species, fungal genera explained 19-34% of the total variance. Some fungal genera, such as Amanita and Collybia, affected the drosophilid community, but not at all developmental stages. The number of fungal genera that significantly affected the insect community composition did not differ among fungal stages both in the whole insect community and in the drosophilid community. Thus, our former hypothesis was supported by the present analysis, whereas the latter was not. However, the percentages of variance explained by fungal genera were rather small. This suggests that the importance of fungal genera is likely to be less significant than that of other selection pressures in determining the species composition of myco- phagous insect communities.
Antecedents and Consequences of Affect-based and Role-based Loyalty of Section Chiefs to Supervisors in Taiwanese Elementary Schools

This study surveyed 660 section chiefs in public elementary schools in Taoyuan and revealed that affect- and role-based loyalty are two distinct types of loyalty to supervisors. The findings indicated that role-based loyalty had a positive impact on affect-based loyalty for section chiefs in public elementary schools. The ethical behavior of supervisors and perceived supervisor sharing vision predicted affect-based loyalty, whereas leadership justice perception and respect for hierarchy predicted role-based loyalty to the supervisor. In addition, affect-based loyalty had positive impacts on word of mouth, supervisor-directed organizational citizenship behavior (OCB) and a negative impact on emotional exhaustion. Role-based loyalty had positive impacts on in-role performance and supervisor-directed OCB. In particular, affect-based loyalty had a greater impact on supervisor-directed OCB than role-based loyalty did.
Harnessing sustainability complexity : a strategy to incorporate social factors into engineering education

As societal expectations have changed from narrowly focused environmental issues to broader sustainable development concerns, it is vital that future engineers graduate with an understanding of how social impacts may affect or may be affected by their decisions. Drawing on complexity theory and sustainability literature, this paper describes how engineering programs can incorporate a course that will enable graduating engineers to explore the interdependencies among technical, economic, environmental and social dimensions of sustainability. System’s elements and interdependences are identified using modularity, a technique that applies deductive and inductive methods. Using the example of a sustainable lignin-based product we demonstrate how such methods are performed in practice. We then discuss the implications for engineering teaching and propose an integrated sustainability analysis course that focuses on harnessing social factors within sustainability complexity, by seeking them out and exploiting interdependencies. This will prepare future engineers to work on a more realistic scenario, and more broadly explore new ideas and possible solutions.
The Effect of the Use of Oxytocin in Labor on Neonatal Jaundice: A Systematic Review and Meta-Analysis

Background: Neonatal Jaundice is a common problem that occurs in most preterm and term neonates. This systematic review aimed to examine the evidence for the effects of oxytocin in labor on neonatal jaundice. Materials and Methods: In this systematic review study, English databases including PubMed, Google Scholar, Embase, Cochrane Library, Scopus, Web of Sciences, and Persian databases including SID, Magiran, and Barakat Knowledge Network System Were searched from Jan 1980 to Dec 2017. Persian and English human clinical trials were targeted. The review was limited to human clinical trials examining the effect of oxytocin in labor on neonatal jaundice. The searched MESH vocabulary was "neonatal hyperbilirubinemia" OR "jaundice" in combination with "oxytocin in labor" OR "induction of labor". Two authors examined the articles separately and the disagreements were resolved through discussion. Results: Out of 583 articles searched in the databases, 440 title, 83 abstracts, and 60 full texts were reviewed, of which 5 English language articles entered the study and 4 articles entered the meta-analysis. Meta-analysis results showed that oxytocin did not affect the serum bilirubin level of the umbilical cord (Mean difference: 1.60; 95% confidence interval [CI]:-2.50 to 5.69; P=0.44; I2=78%). Furthermore, administering oxytocin in labor did not significantly affect serum bilirubin level on days 1 (-0.32; -1.36 to 0.71; P=0.54; I2=72%), and day 3 (3.75; -11.76 to 18.90; P=0.65; I2=63%), while it significantly affected serum bilirubin level on day 2 (-1.63; -2.81 to -0.45; P=0.007; I2=0%). Conclusion: The result of meta-analysis showed that the administration of oxytocin during labor does not affect serum bilirubin level on days 1 and 3, while induction of labor with oxytocin causes serum bilirubin to increase on the second postnatal day. However, due to the high heterogeneity of the studies, better designed clinical trials are recommended to achieve better results.
The coexistence of traditional and large-scale water supply systems in central northern Namibia

Looking at recent research projects in the field of water resources management, it often seems that historical, social and cultural issues are not taken into account fully. In this paper, a methodology and its application are presented which address and overcome these shortcomings. Interviews with relevant regional stakeholders provide a deeper insight into the interrelations in the system. The area of investigation is the so-called Cuvelai-Etosha-Basin which is located in central northern Namibia. It is estimated that 1 million people live in this area, which is approximately half of the Namibian population. There are no perennial rivers within the region and groundwaters are saline. To supply the population with potable water, a large technical system has been established which is fed by the Namibian-Angolan border river Kunene. However, at the same time, traditional water supply techniques such as Oshanas and excavation dams (Ometale), shallow dug wells (Omuthima), dug wells (Oshikweyo), and rainwater harvesting play a considerable role. Preliminary results of the PhD project are presented in this article in the form of perceptions and opinions of the interviewees.
ON THE COOPERATIVE AND DOPPLER DIVERSITY FOR AMPLIFY-AND- FORWARD RELAY NETWORK

This paper investigates Cooperative and Doppler diversity for Amplify-and-Forward (AF) relay network assuming the channel between Mobile Station (MS)s and Relay Station (RS)s as well as the channel between the RSs and Base Station (BS) are nonstationary. More specifically, this paper analyzes and demonstrates how both the Doppler and cooperative diversities can be achieved to improve the system performance of an AF relay network in high user mobility scenario. To facilitate the analysis, a model for 011hogonal Frequency Division Multiple Access (OFDMA) based AF relay is developed. The time varying channel is modeled using Basis Expans ion Model (BEM). Using both models we present efficient signal detection methods which can exploit the Doppler spread to improve Symbol Error Rate (SER) performance. Theoretical analysis together with simu lation results are presented to demonstrate the improvement on system performance.
Remote sensing monitoring to preserve ancestral semi-natural mountain meadows landscapes.

“Lameiros” are ancestral semi-natural meadows, essential elements of mountain landscapes in Northern Portugal. In the “lameiros” a traditional irrigation system is used and water is applied all year around. They are mainly used for forage production for autochthonous bovine feeding, but they are also important for the water and nutrients cycle regulation, erosion control and as barrier to forest fires propagation. Although recognized for their economical, environmental, landscaping, cultural and genetic value, the perpetuation of these “lameiros” could be at risk, at medium term, due to human desertification in the mountain regions and to the announced constraints in use of water resources. To preserve these landscapes it is essential to know them better and to better characterize them. Therefore a monitoring program using remote sensing tools is now being developed to evaluate different patterns of “lameiros”, and their spatial extent and evolution. Two important questions are determinant in this program: the selection of the most appropriate spatial resolution for monitoring “lameiros”, and the availability of satellite historical data. In this context, NDVI were compared in two selected test sites, with and without full irrigation. Data were derived from several field campaigns with a spectroradiometer and using different sensors: i) Landsat 5 and Landsat 7 (30m pixel), ii) SPOT 4 and SPOT 2 (20m pixel), iii) SPOT 5 (10m pixel). The NDVI temporal series produced were evaluated considering “lameiros” management and weather data. Results obtained so far indicate that the SPOT images provide data at the most adequate scale.
The Consequences of Measurement Error When Estimating the Impact of BMI on Labour Market Outcomes

This paper uses data on both self-reported and true measures of individual Body Mass Index (BMI) to examine the nature of measurement error in self-reported BMI and to look at the consequences of using self-reported measures when estimating the effect of BMI on economic outcomes. In keeping with previous studies we find that self-reported BMI is subject to significant measurement error and this error is negatively correlated with the true measure of BMI. In our analysis this non-classical measurement error causes the traditional approach to overestimate the relationship between BMI and both income and education. Furthermore we show that popular alternatives estimators that have been adopted to address problems of measurement error in BMI, such as the conditional expectation approach and the instrumental variables approach, also exhibit significant biases.
