Social media usage among wine tourism DMOs

Social media is an important tool for tourism destination promotion. The usage and the contents published on these platforms have an important role in visitors’ decision-making process. Information and communication technologies are changing DMOs’ markets and communication paradigm, since they allow the interaction between these organizations, visitors, and stakeholders. Therefore, social media are increasing their relevance on DMOs’ marketing strategies. This purpose of this study is to analyze comparatively social media platforms’ usage by six wine tourism DMOs. The results were provided by the analysis of secondary data available on these platforms and DMOs posts on the four most popular social media platforms to tourism industry: Facebook, Instagram, Twitter, and YouTube. Results indicate that DMOs use their official accounts on these platforms on different ways. This study also reveals that Facebook is more interactive than other platforms, and YouTube achieves less engagement levels.info:eu-repo/semantics/publishedVersio

Pecking order theory versus trade-off theory : are service SMEs’ capital structure decisions different?

This paper seeks to analyse if the capital structure decisions of service small and medium-sized enterprises (SMEs) are different from those of other types of firm. To do so, we consider four research samples: (i) 610 service SMEs; (ii) 126 service large firms; (iii) 679 manufacturing and construction SMEs; and (iv) 132 manufacturing and construction large firms. Using the two-step estimation method, the empirical evidence obtained in this study shows that the capital structure decisions of service SMEs are different from those of other types of firm. Service SMEs’ capital structure decisions are closer to the assumptions of Pecking Order Theory and further removed from those of Trade-Off Theory compared with the case of other types of firm

Soil organic carbon sequestration as affected by afforestation: the Darab Kola forest (North of Iran) case study

Following the ratification of the Kyoto Protocol, afforestation of formerly arable lands and/or degraded areas has been acknowledged as a land-use change contributing to the mitigation of increasing atmospheric CO2 concentration in the atmosphere. In the present work, we study the soil organic carbon sequestration (SOCS) in 21 year old stands of maple (Acer velutinum Bioss.), oak (Quercus castaneifolia C.A. Mey.), and red pine (Pinus brutia Ten.) in the Darab Kola region, north of Iran. Soil samples were collected at four different depths (0\u201310, 10\u201320, 20\u201330, and 30\u201340 cm), and characterized with respect to bulk density, water content, electrical conductivity, pH, texture, lime content, total organic C, total N, and earthworm density and biomass. Data showed that afforested stands significantly affected soil characteristics, also raising SOCS phenomena, with values of 163.3, 120.6, and 102.1 Mg C ha 121 for red pine, oak and maple stands, respectively, vs. 83.0 Mg C ha 121 for the control region. Even if the dynamics of organic matter (OM) in soil is very complex and affected by several pedo-climatic factors, a stepwise regression method indicates that SOCS values in the studied area could be predicted using the following parameters, i.e., sand, clay, lime, and total N contents, and C/N ratio. In particular, although the chemical and physical stabilization capacity of organic C by soil is believed to be mainly governed by clay content, regression analysis showed a positive correlation between SOCS and sand (R = 0.86**), whereas a negative correlation with clay (R = 120.77**) was observed, thus suggesting that most of this organic C occurs as particulate OM instead of mineral-associated OM. Although the proposed models do not take into account possible changes due to natural and anthropogenic processes, they represent a simple way that could be used to evaluate and/or monitor the potential of each forest plantation in immobilizing organic C in soil (thus reducing atmospheric C concentration), as well as to select more appropriate species during forestation plan management at least in the north of Iran
