        We present an ongoing study of the complete sample of supernova remnants (SNRs) and candidates in the Magellanic Clouds. 108 objects in both Clouds are considered to be either SNR or reliable candidates. This represents the most complete sample of all known SNRs in any galaxy. It therefore allows us to study SNR population properties such as the age-diameter (Age-D) relation. Here, we show that this Age-D relation is strongly dependant on the local environment in which SNRs are residing.

        We describe a survey of nearby core-collapse supernova (SN) explosion sites using integral field spec- troscopy (IFS) techniques, which is an extension of the work described in Kuncarayakti et al. (2013). The project aims to constrain SN progenitor properties based on the study of the immediate environment of the SN. The stellar populations present at the SN explosion sites are studied by means of integral field spectroscopy, which enables the acquisition of both spatial and spectral information of the object simultaneously. The spectrum of the SN parent stellar population gives an estimate of its age and metal- licity. With this information, the initial mass and metallicity of the once coeval SN progenitor star are derived. While the survey is mostly done in optical, the additional utilization of near-infrared integral field spectroscopy assisted with adaptive optics (AO) enables us to examine the explosion sites in high spatial detail, down to a few parsecs. This work is being carried out using multiple 2-8 m class telescopes equipped with integral field spectrographs in Chile and Hawaii.

        We made phase-referencing Very Long Baseline Interferometry (VLBI) observations of Galactic 22 GHz H2O maser sources with VLBI Exploration of Radio Astrometry (VERA). We measured the parallax dis- tances of G48.61+0.02, G48.99-0.30, G49.19-0.34, ON1, IRAS 20056+3350, IRAS 20143+3634, ON2N, and IRAS 20126+4104, which are located near the tangent point and the Solar circle. The angular ve- locity of the Galactic rotation at the LSR (i.e. the ratio of the Galactic constants) is derived using the measured parallax distances and proper motions of these sources. The derived value of Ω0 = 28:8  1:7 km s-1 kpc-1 is consistent with recent values obtained using VLBI astrometry but 10% larger than the International Astronomical Union (IAU) recommended value of 25.9 km s-1 kpc-1 = (220 km s-1) / (8.5 kpc).

        In photobiophysics, biophoton means a kind of biological energy which enhances most metabolisms of the body. To investigate the immuno-enhancing effects of biophoton energy projector (BEP) producing light energy, pigs were irradiated with BEP for 8 weeks. Swine peripheral blood mononuclear cells (sPBMCs) were isolated from the blood of irradiated pigs. In this study, the antigen uptake and mitochondrial membrane potential of sPBMCs were measured by flow cytometric analysis. The irradiation of BEP increased the antigen uptake of sPBMCs. For functional analysis, the production of Bordetella bronchiseptica-specific IgG, measured using antigen-specific ELISA, was increased during the period of BEP irradiation. Taken together, the results suggest that the irradiation of BEP has immune-enhancing effects on sPBMCs.

        The surfaces of most atmosphereless solar system objects are referred to as regolith, layers of loosely connected fragmentary debris, produced by meteorite impacts. Measurements of light scattered from such surfaces provides information about the composition and structure of the surface. A suitable way to characterize the scattering properties is to consider how the intensity and polarization of scattered light depends on the particle size, composition, porosity, roughness, wavelength of incident light and the geometry of observation. In the present work, the effect of porosity on bidirectional re ectance as a function of phase angle is studied for alumina powder with grain size of 0.3 μm and olivine powder with grain size of 49 μm at 543.5 nm. The optical constants of the alumina sample for each porosity were calculated with Maxwell Garnett e ective medium theory. On using each of the optical constants of alumina sample in Mie theory with the Hapke model the variation of bidirectional re ectance is obtained as a function of phase angle with porosity as a parameter. Experimental re ectance data are in good agreement the model. For the olivine sample the effect of porosity is studied using Hapke (2008).

        The purpose of this research is to study the evolution of the price of Burgundy wines and to try to identify the reasons for such an evolution. Land prices, rent prices and wine prices in Burgundy will be analysed over the last decades. In terms of results, the price of wine in Burgundy has been observed to rise drastically in recent years as well as the evolution of land and rent prices. A better comprehension of price variations could help wine companies manage their long term profitability, especially if land were considered as an investment (and therefore, part of the company). As a recommendation, marketing tools but also training should be used by craftsmen to build, promote and distribute strong brands in order to remain on the market but also to attract major agents and importers and be distributed worldwide.

        Fashion brands are influenced by multiple identities. Even though, for example, the brand name might still be associated with one or more creative founders (Gucci, Prada, Chanel, Hermès, Adidas, Joop) the brand image, and moreover the overall brand reputation are influenced by many different identities. For instance, a specific product identity (e.g., Gucci’s Bamboo Bag), the identity of the city or country of origin (Florence, Italy), the identities of well-known key customers as brand ambassadors (Sophia Loren, Vanessa Redgrave, Lady Diana, Naomi Watts etc.). Of course, also fashion brands who are not directly associated with the name of creative founders are composed of the effects of several identities. In the case of e.g. Nike especially successful athletes (Steve Prefontaine, Michael Jordan etc.), specific sports and sport events, and product lines tailor-made for them did help to build a strong brand reputation. All in all, it seems to be expedient to understand fashion brands as more of less complex systems composed of several identities. To deal in more detail with such “brand systems” is becoming particularly important against the background of several strategic challenges – e.g., when fashion brands are growing older and the creative founders lose their specific gravitational power, when in the process of internationalization new countries gain more and more importance who’s citizens might not have a strong access to the existing brand reputation drivers, or simply when in the context of the growing global competition the fashion brand needs to be “refreshed”. Against the background of cultural differences, or even - as within countries - lifestyle differences between different groups of customers, it can also be quite possibly that very different reputation drivers account for the success of a brand. Thus, it is necessary to identify, in different contexts, the relevant reputation drivers, and to analyze which interplay of those drivers might be particularly promising. Is it the creative founder, the corporate heritage, the country and/or city of origin, a special designer, a specific corporate culture, an outstanding product design, attractive key customers etc.? Which combination of such identity factors leads to what kind of success (e.g., brand loyalty, brand trust, price premium)? Will, for instance, heritage especially lead to brand trust, whereas an outstanding product design and specifically attractive key customers create the readiness for a higher price premium? And, is it necessary to create sub-brands to especially highlight specific identities in the process of building a brand system (e.g., the sub-branding of a Michael Jordan product line in the case of Nike)? Or is sufficient to only communicate an alignment with the brand (e.g., ads showing Naomi Watts wearing a Gucci Bamboo Handbag)? In other words, which kind of brand system, and which kind of brand communications has to be designed to attract specific target groups and to sustain competitive advantages? The present contribution aims to present a conceptual framework for analyzing “brand systems” in the fashion industry. Concomitantly, an approach of measuring such brand systems will be presented. Furthermore, a concept for analyzing the impact of several sub-identities on the development of the overall brand reputation and brand success against the background of existing contingencies will be outlined. With the introduction and discussion of such a conceptual framework it especially is intended to initiate the launching of an international research project which attempts to find an answer basically to the following question: Which via an integrated branding and brand systems communication carefully crafted composition of sub-identities might be how successful under what kind of situational conditions?

        For many brands, offering valuable and original experiences for customers is the main means of gaining awareness, image values and hence, strategic competitive advantage. Brands like Abercrombie and Fitch, BONOBOS and Victoria’s Secret have understood the opportunities offered by experiential marketing as a new philosophy of thinking, conceiving and proposing a marketing offer. This challenge is as important for online fashion brands that target millennial customers considered as internet addicts (Bergman et al., 2005) always looking for information, exhibitionism and enjoyable online experiences. With the growth of online fashion shopping it is important that fashion retailers pay attention to the relationship between specific website quality dimensions and customer satisfaction (Kim and Stoel, 2004). Fashion brands must go beyond the vision of the website as a medium of information to a medium of entertaining proposing additional extraordinary and optimal experiences for these customers. As noted by Kim (2007), online fashion retailers need to be able to communicate the product information virtually in order to create accurate product perceptions for consumers who are visiting their website. Thus, the main question is “what are the elements of the website which could help achieve these aims?” There has been little empirical research which focuses on how information features affect consumers` commitments to a shopping site on the web (Park and Kim, 2006). Consequently,the main aim of this paper is to further research in the domain by illustrating how the online fashion brand provides a valuable shopping, consuming and cognitive experience that fits with the consumer’s expectations aligning these with the extraordinary and symbolic world of the brand. From this perspective, the website of the brand – due to its multisensory, interactive and hyper-mediatized nature – can be a very effective digital support for achieving these goals. It represents the virtual environment that enables the brand to create and open up a universe that transcribes its functional, experiential and symbolic values. From the consumer’s psychological perspective, this online communication strategy questions the psychological process that underlines the perception, elaboration and reactions of the consumer during his online experience: To this is end, it is relevant to focus on the influences of the usability of the website on the attributes of the mental images the consumer experiences and the moderating role that brand attitude and involvement in the product category could have in this. Also, based on MacInnis and Price (1987) recommendations, it is relevant to analyze the role the consumer’s style of processing could have in this process. Thus, the research questions are: How do the attributes of the website impact the mental imagery experience of the consumer during his/her website visit?; and what are the consequences of these psychological reactions on the consumer’s post-visit attitude and behavior. In attempt to respond to these questions, we explore the psychological process that underlies consumer online behavior. We draw on the literature which emphasizes the link between the website attributes and the imagery processing of the online consumer. We present and empirically test our conceptual model within the current quantitative study. We follow with a discussion of our results and presentation of the implications of our study for theory and practice.

        Greece wine production has shown swinging trends: in 2013 it grew by 17,9% reaching 3.7 Million Hectoliters (USDA), but it 2014 it decreased by 15% (Greek Wine Federation), whilst grape prices went up. Greece has a huge potential, but it is still a small producer in Europe. The Greek wine industry got through several phases: before the 80s the product was quite “poor”, but with the entrance in the market of some educated winemakers who have introduced a new business philosophy and approach to wine, production has changed (GaiaWines.gr). The population of firms consist of a few larger producers, and most of the companies are relatively small. Although the quality has been improved, most of the production is addressed to the domestic market, since only few producers have established export networks (Vlachvei et al., 2012). Thus, the economic crisis that affected Greece has created difficulties also for domestic sales. Background research has outlines some of the limits of the Greek wine industry: according to Vlachvei et al. (2012),the new competitive challenges require owner and managers to achieve a better understanding of operational and marketing process that can contribute to the development of their brand in order to develop an integrated marketing communication approach. The Greek wine sector is extremely fragmented with a high predominance of small size firms; as size increases, the degree of professional organization grows, as well as the relative presence of foreign markets (Papalexiou, 2009). Thus, it has been recognized that Greek wine export is disorganized (Baiocchi, 2011; Papalexiou, 2009). The limits imposed by UE to plantings have affected Greece growth strategy: Greece is still a small producer and although it shows similarities with the south of Italy, it is impossible to think to follow the “Italian Style” (Baiocchi, 2011). Thus the urgency of undertaking a propter model for the development of the industry is seen as a priority for the Greek wine system. Wineries have seen in related businesses an effective tool for improving the competitiveness of the wine industry (Papalexiou, 2009); a lot has been done for achieving an integration between wine tourism and the wine business. Background research describes the experiments undertaken around wine routes, conceived as a useful tool for improving the wine sector (Hall & Mitchell, 2000) and for the development of rural areas (Karafolas, 2007). In 2014 the Joint Research Center (JRC) of the European Commission has undertaken a Smart Specialization pilot project that involves rural areas in Northern Greece, in order to foster local economic development by adopting an entrepreneurial discovery approach (EDP). JRC can be considered as a source of technology generation and a service that provides expert advice to the institutions of the European Union and more specifically to the European Commission and the European Parliament (Moncada-Paterno`-Castello, 2003). It can be guessed how JRC outcomes could impact citizens’ lives. From September 2014 for 15 months JRC has been involved in the European Parliament Preparatory Action; the aims of this project are: to facilitate the refinement and implementation of the RIS3 strategy in a region heavily hit by the crisis; and to serve as a model for other convergence regions in Greece and Europe (from JRC website). The project has seen the collaboration of JRC – IPTS (Institute for Prospective Technological Studies) with DG Regio and the Managing Authority of Eastern Macedonia and Thrace. The wine sector has been selected, together with few others for the preparatory action. The approach that has been adopted was the Entrepreneurial Discovery Process (EDP), in order to allocate resources under the guide of entrepreneurial actors, from the public and private sector. EDP is “a process in which the entrepreneurial actors are discovering and producing information about new business and innovation activities and the government is collecting, assessing and transforming this knowledge into policy action” (http://s3platform.jrc.ec.europa.eu/s3-governance).EDP plays a leading role in the Smart Specialization Strategy (S3): EDP suggests that the allocation of resources is the result of a process undertaken by entrepreneurial actors. It emerges how innovative this process is, if compared to past industrial policies. EDP contributed to minimise failures of market innovation. The Smart Specialisation perspective let entrepreneurs discovering the right domains of future specializations (Foray, 2012). A newer approach to regional competitiveness (Ketels, 2013) has been followed by European Commission, that, in order to promote an efficient and effective public funding policy in regional economic development (Mempel-Śnieżyk, 2013), has actively supported Smart Specialisation Initiatives. On the other side, S3 has a prior role in the EU Regional and Cohesion Policy 2014-2020 (Martínez-López & Palazuelos-Martínez, 2014). This paper examines the role that EDP and S3 have had in the definition of a strategy for the development of the local wine industry. The paper aims to answering to the following research questions: What are the elements seen as priorities from entrepreneurs for developing the local wine industry in Greece? Is there an overlapping between the findings emerging from JRC workshops and those that have been pointed out by relevant opinion makers and experts in the Greek wine industry? What about the effectiveness of EDP in wine? The paper is structured as follows: In the first part a description of the Greek wine industry will be carried out; in a second section authors will point out JRC’s EDP approach; thirdly an analysis of data collected from JRC sessions and from interviews with international experts in Greece will be performed. 9 experts that took part to the workshop will be interviewed. Data will be collected through telephone interviews and web based survey; once collected data will be analyzed through a text analysis. A literature review on EDP and theoretical issues that have inspired the organization of JRC sessions will be presented in order to support Research Questions. The papers ends up with a discussion and conclusions in order to provide inputs for professionals, and policy makers.

        Research aim and objectives Fashion blogs are personal online diaries created in order to collect and spread information about fashion trends, products and brands for a community of followers. Since their advent, fashion bloggers became key players in the field of fashion (Rocamora, 2011). Some fashion blogs achieved so much fame and notoriety to establish themselves as crucial reference points for consumers, fundamental spaces for “the production and circulation of fashion discourse” (ibidem, p.409). This exponentially growing phenomenon revolutionized the world of fashion and the concept of fashion industry itself: fashion bloggers have been included in the institutional system of fashion, beside the traditional media industry and considered together with the fashion journalism (Pedroni, 2014). The relevance of this research field is proved by the fashion bloggers’ copious and promising revenue. It is estimated that the most successful bloggers have incomes which soar into the million-dollar range annually (Blalock, 2014). According to Forbes (2015), Chiara Ferragni, the owner of ‘The Blonde Salad’ which became the Harvard’s Business School case study, is on track to take in $8 million in revenues this year. The most of the revenue comes not only from website advertisement but from celebrity appearances, partnership with luxury brands and bloggers’ handbag, shoes and clothes line collections (Keinan et al., 2015). However, despite it constitutes an extremely appealing domain for marketing studies (Kim & Jin, 2006), research on fashion blogging is still incipient (Rocamora, 2011). As the bloggers are brands themselves, the aim of this research is to deepen the fragmentary understanding of this phenomenon through the adoption of a personal brand perspective, i.e. personal branding. In order to achieve this aim, the following objectives have been set: - How do the fashion bloggers develop and turn their personal identity and value into a personal brand? - What are their communication strategy? - What are their interaction strategies? Personal Branding: an overview The expression “personal branding” was introduced for the first time by Tom Peters (1997) in his article emblematically entitled “The brand called you”. In his contribution, considered to be the manifesto of personal branding, Peters points out the dramatic changes that affected the labour market, suggesting that the only way for people to succeed in a highly competitive scenario is to transform themselves into Chief Executive Officers of their own company and promote themselves learning from some of the most successful brands as Nike, Coke, Pepsi (ibidem). Personal branding (also known as self-branding, cf. Kaputa, 2003) is based on the idea that it is possible to apply to people the same marketing and branding principles originally developed for products and companies (Sheperd, 2005). It can be defined as a process by which individuals recognize their strengths and uniqueness and promote themselves to a target audience. In other words, building a personal brand means to identify what makes a person unique and different from their competitors or peers, but it also refers to the ability to communicate, in an effective way, your own source of competitive advantage (Centenaro and Sorchiotti, 2013; Kaputa, 2012; Labrecque, Markos & Milne, 2011; Shepherd, 2005). Although Peter’s (1997) original idea of personal branding was more generally based on individuals facing the “off-line” labour market, this approach can be used also to explain some “on-line” phenomenon. New technologies, in fact, created computer mediated environments, resulting in virtual spaces where people can present and express themselves using digital traces (Schau and Gilly, 2003). Research Methodology Using in-depth interviews and netnography, this work examines how a group of popular Italian fashion bloggers managed to build their personal brands and grow their value. A multi-methods research based on the combination of no-structured interviews (conducted both face-to-face and through Instant Messaging channels) and a netnographic approach1 was used to analyze the fashion blogging phenomenon. The in-depth interviews involved four Italian fashion bloggers selected with a snowball sampling. These interviews, performed in the explorative phase of the research, in addition to provide a preliminary exploration of the fashion blogging scenario and first empirical evidence, favoured the development of categories of analysis that have been successively deepened through the netnographic approach. The netnographic analysis, started in April and still in progress, has been applied to fifteen Italian fashion blogs, selected among the 100 most followed blogs indicated by Les Cahiers Fashion Marketing, an online fashion marketing magazine. Among them, the blogs selection was performed following the criteria suggested by the literature about netnography (Kozinets, 2010): the presence of relevant information related to the research focus and questions; the presence of recent and regular communication and a large interactivity between the blogger and other participants2; the occurrence of detailed and descriptively rich data. Drawing lessons from the literature (ibidem)3, data collection was performed trough a non-participant observation approach, that has allowed researchers to collect data in a completely unobtrusive manner and work on naturally occurring texts, not distorted in any way by the analyst’s presence. The collected data included both bloggers’ posts and audience’s comments. Moreover, in addition to textual material, visual and audiovisual data have been collected and analyzed. During the analysis, two different processes of netnographic analysis, analytical coding and hermeneutic interpretation, have been usefully combined and performed. In the following paragraph, the first results obtained, until now, through a combined analysis of excerpts of interviews and netnography will be shown. Results Preliminary research evidence shows that the success of a fashion blogger depends mainly on: • A clear definition and development of a personal identity; • The effort to coherently convey the personal identity through an effective management of different communication and interaction tools; • The development of a network that can maximize blogger’s visibility and notoriety. Identity and value dimension: self-presentation strategies Blogs are usually presented as spaces in which an authentic personal style can be expressed. Analyzing the bloggers’ entries, it is possible to recognize how the concept of personal style plays a fundamental role, representing the main element on which the blogger’s identity is based (Kulmala, Mesiranta and Tuominen, 2013). The most important tool for the expression of the blogger’s personal style is posting the outfit of the day: i.e. an outfit worn on a particular day or during a particular event or occasion, based on the combination of different brands and products. As bloggers and readers’ attention is not focused on specific products and brands, but, rather, on how single pieces of clothing are assembled and combined together, every daily outfit works as a style statement expressing and reinforcing the blogger’s personal identity and, at the same time, provides inspiration and identification by his followers (Pihl, 2014). Communication strategy: style and tools The netnographic analysis shows how the starting level of the published contents is very amateur, where the bloggers usually lack a well-defined communication strategy. However, observing the sampled blogs through a diachronic netnographic approach, it is possible to recognize a gradual change involving both the writing style and the visual elements. Texts became better-finished, effective, studied in detail, with continuous intertextual references to older posts about similar or related topics. The products or brands presentation and description are never de- contextualized, but always inserted within a narrative structure. In other words, fashion bloggers make use of the potentials offered by visual storytelling, presenting products as a part of bloggers’ daily life, always intertwined with bloggers’ autobiographical information (Rocamora, 2011). Simple and interesting personal stories are displayed in order to allow readers to identify themselves with the blogger and his core values. Moreover, pictures are taken in a very professional way, paying close attention to every element as light, colours, and locations. In addition to the daily update of the blog, bloggers’ communication strategy embraces the logics of a pervasive personal branding by managing different platforms like Facebook, LinkedIn, Pinterest and Instagram in order to build a strong and coherent diffused identity on the net. Interaction strategies: network and partnerships The relational dimension involves three main types of relations. First, with readers: bloggers try to ensure audience’s engagement and loyalty, encouraging readers to express their opinions about the proposed outfit; provide customised advice and suggestions; promote their active participation through contests and giveaways. On the other hand, users use comments to support the blogger’s activity, show their approval for the proposed outfits or suggest modifications and variations to the blogger’s proposal. Secondly, the relational dimension concerns the connections with other bloggers: fashion blogs define together a community of style (Pihl , 2014), a real network characterized by continual mutual references among its nodes. It is especially through the tools of comments that bloggers promote each other, posing at the bottom of the comments links to their blog and inviting other readers to visit it. Finally, the relational dimension concerns the relationships between bloggers and fashion brands. The analysis of the in-depth interviews puts in evidence that collaboration dynamics frequently established between fashion brands and bloggers can take different forms: from inviting the blogger to choose specific brand products and give them visibility through a review on the blog, to invite the blogger to take part as a guest or model in a fashion parade or new collection presentation or in a brand photo shoot. These forms of cooperation can take more structured forms and transform into more complex co- branding strategies: there many examples of bloggers that, in partnership with well- known brands, realize and launch limited or special products edition. Implications and limitations According to our preliminary results, the success of a fashion blogger depends mainly on his ability to transform the blogging activity into a personal brand. In some cases, the branding process reaches its highest fulfilment when the blogger launches and promotes a personal collection resulting in an independent fashion brand. The interest in the phenomenon for marketers mainly derives from the different forms of collaboration that can be established between bloggers and fashion companies. For bloggers, those partnerships represent important occasions to enrich their portfolio and increase their reputation and credibility by the target audience. On the other hand, fashion companies can use blogs as a tool to collect decisive information about consumers (cf. Kulmala et al., 2013), exploit the visibility and reputation of fashion bloggers and benefit of an extremely powerful communication means. In fact, as bloggers use their own language, their messages are considered to be more direct, intimate and authentic by readers. As this study has an explorative nature, it is not aimed at generalizing its results, but rather at deepening the knowledge about a still underdeveloped and uncertain phenomenon, i.e. the Italian fashion blogging. However, the research has been performed following the evaluative criteria proposed by literature about netnography (Kozinets, 2010), i.e. coherence, rigour, verisimilitude and innovation.

        This paper aims to investigate the alignment between fashion companies’ CSR policy, as communicated through company website, and CSR retail practices customers can actually observe or get information about when visiting company’s retail stores. The case study analysis is carried out using the Mystery Shopping technique. The sample is made up of companies belonging to the top of the fashion luxury pyramid, whilst the visited stores are located in Italy. The purpose of this paper is to provide a classification of companies’ behaviours in deploying CRS policy at the retail level, and to highlight different levels of fit between companies’ CSR policy and CSR practices communicated at the retail-store level. Our results reveal that several companies show a mismatch between their CSR policy and CRS practices communicated in stores to customers.

        Aging water pipe networks hinder efficient management of important water service indices such as revenue water and leakage ratio due to pipe breakage and malfunctioning of pipe appurtenance. In order to control leakage in water pipe networks, various methods such as the minimum night flow analysis and sound waves method have been used. However, the accuracy and efficiency of detecting water leak by these methods need to be improved due to the increase of water consumption at night. In this study the Principal Component Analysis (PCA) technique was applied to the night water flow data of 426 days collected from a water distribution system in the interval of one hour. Based on the PCA technique, computational algorithms were developed to narrow the time windows for efficient execution of leak detection job. The algorithms were programmed on computer using the MATLAB. The presented techniques are expected to contribute to the efficient management of water pipe networks by providing more effective time windows for the detection of the anomaly of pipe network such as leak or abnormal demand.

        Most religious teachings support the idea that money and materialism are at the root of all evil. However, reality is not so rigorous and many times materialism seems even a blessing. The purpose of this study is to investigate and compare religious and non-religious consumer on their perspective toward materialism, and through it, luxury brand and purchase intention. The total sample consisted of 491 university Asian students. Results show that religious consumers are not necessarily against neither materialism nor luxury brand possession. Consumers’ religiosity did not influence their perspective toward materialism or luxury goods. This creates an opportunity for managers to promote luxury brand toward religious consumers especially in Asia, where religion is more prevalent.
