As a crucial part of producer services, the logistics industry is highly dependent on the manufacturing industry. In general, the interactive development of the logistics and manufacturing industries is essential. Due to the existence of a certain degree of interdependence between any two factors, interaction between the two industries has produced a basis for measurement; identifying the key factors affecting the interaction between the manufacturing and logistics industries is a kind of decision problem in the field of multiple criteria decision making (MCDM). A hybrid MCDM method, DEMATEL-based ANP (DANP) is appropriate to solve this problem. However, DANP uses a direct influence matrix, which involves pairwise comparisons that may be more or less influenced by the respondents. Therefore, we propose a decision model, Grey DANP, which can automatically generate the direct influence matrix. Statistical data for the logistics and manufacturing industries in the China Statistical Yearbook (2006–2015) were used to identify the key factors for interaction between these two industries. The results showed that the key logistics criteria for interaction development are the total number of employees in the transport business, the volume of goods, and the total length of routes. The key manufacturing criteria for interaction development are the gross domestic product and the value added. Therefore, stakeholders should increase the number of employees in the transport industry and freight volumes. Also, the investment in infrastructure should be increased.

Gelatin production is the most industry polluting process where huge amounts of raw organic materials and chemicals (HCl, NaOH, Ca2+) are utilized in the manufacturing accompanied by voluminous quantities of end-pipe effluent. The gelatinous wastewater (GWW) contains a large fraction of protein and lipids with biodegradability (BOD/COD ratio) exceeding 0.6. Thus, it represents a promising low-cost substrate for the generation of biofuels, i.e., H2 and CH4, by the anaerobic digestion process. This review comprehensively describes the anaerobic technologies employed for simultaneous treatment and energy recovery from GWW. The emphasis was afforded on factors affecting the biofuels productivity from anaerobic digestion of GWW, i.e., protein concentration, organic loading rate (OLR), hydraulic retention time (HRT), the substrate to inoculum (S0/X0) ratio, type of mixed culture anaerobes, carbohydrates concentration, volatile fatty acids (VFAs), ammonia and alkalinity/VFA ratio, and reactor configurations. Economic values and future perspectives that require more attention are also outlined to facilitate further advancement and achieve practicality in this domain.

Research background: The global environment influences the behaviour of companies. This concerns the requirements for increasing number of products, product lines, brands, the need for market segmentation, consumer demand, innovations as well as the behaviour of consumers and suppliers including environmentally appropriate purchasing. The forest-based industries must respond to changes from the perspective of the globalization process by appropriate adaptation and, inter alia, to focus on the introduction of environmentally properly procurement. The integration of green purchasing principles into business systems is increasingly mentioned in the process of globalization of economies in connection with the huge potential for gaining a sustainable competitive advantage. Purpose of the article: The aim of the paper is to identify and analyze the factors affecting the implementation of environmentally friendly purchasing in the companies of forest-based sector in Slovakia. Methods: The reasons for implementing responsible practices in supply chains are based either on the stakeholder theory or the assumption that companies have a more proactive approach to implement sustainable purchasing practices as they are aware of the possible benefits. Using a questionnaire survey the companies operating in all sub-sectors of the forest-based industry - wood, pulp and paper and furniture manufacturing, including their suppliers of wood raw material in Slovakia, were questioned with the aim to identify the reasons for implementing sustainable purchasing practices. Findings & Value added: Data obtained are used to identify the factors that are crucial for the introduction of green purchasing in companies in dependence on the specific company characteristics and conditions of the market environment under which companies operate.


With the automobile sector pacing the tracks among their competitors to lead the market and adopting eco-friendly technologies, a much economic and vital field of making use of the manufactured product beyond its useful life span is widely neglected. This paper throws light on the necessity for implementing and highlights the various reasons for which these guidelines have not come to the attention of the responsible organizations including law making agencies, automobile manufacturers and as well the consumers. An interpretive structural modelling analysis is made to point out ten driving factors in consultation with various experts from the relevant fields and the results provide guidance to how far the idea of design for dis-assembly and re-manufacturing has sought the world for the sustainability of the automobile manufacturers in the industry, for the days to come.

AbstractFactors that affect the decision to feed or sell calves at weaning are analyzed for Arkansas cow-calf operators. A discrete choice logit model is used to analyze the adoption of value-added cattle production. Farm size, human capital, perception of risk/returns and enterprise diversification are hypothesized to explain this decision. Regional factors and land quality are also accounted for. Operator perceptions towards risk, profitability and facilities were important. Production control and attention to marketing were also significant, but farm size and scale of cattle production had a minimal impact. Effects of human capital and off-farm labor opportunities need further investigation.

As firms grow, taxation and, in particular, value added tax (VAT), is one of the first areas in which they must deal with government regulations. It has been argued in the United Kingdom that regulatory requirements are burdensome and can even be a constraint on the development and growth of small and medium-sized enterprises (SMEs). The authors focus on SMEs and link the literature on VAT regulations and compliance costs to wider issues relating to SMEs. The costs of complying with VAT regulations are separated into core costs and total costs. Core costs are the mandatory costs that SMEs have to incur in order to comply with the VAT legislation and regulations. Total costs include VAT planning and one-off costs. For SMEs core costs represent a larger proportion of total compliance costs than is the case for larger businesses. A reduction in core costs would have a significant impact on the total VAT-compliance costs for SMEs. Factors expected to be associated with higher compliance costs are identified and tested in a multivariate framework. Empirical data were obtained from a survey of 4796 firms resulting in a final sample of 1085 firms and a response rate of 25.1%. Higher compliance costs (in absolute terms) are associated, inter alia, with increased turnover, newly registered firms, and increased complexity. Firms with higher compliance costs also perceived high psychological costs of VAT compliance. Compliance costs were also higher for individuals who did not have English as their first language, and individuals with special needs. The important implications of the findings for policy are highlighted.

AbstractDuring the twenty-five years of existence, water quality has declined and severe blooms of cyanobacteria have occurred in the Grlište Reservoir. Changes in phytoplankton functional groups over time and along horizontal and vertical gradients were investigated in the course of a one-year study in this water-supply reservoir. We identified 19 dominant taxa, classified into 12 phytoplankton associations. The presence of the codons C, P, D and S1 differentiated the transitional from the lacustrine part of the reservoir. The nitrogen-fixing cyanobacteria Dolichospermum viguieri dominated the phytoplankton community in the epilimnion during August and September, when the reservoir showed P-limitation, but the bloom was not observed. The driving factors that accounted for the main variability in phytoplankton functional groups along the seasonal and vertical profile were identified using the direct gradient analysis (RDA). Our results revealed the importance of two bipolar factors. The first factor explained the variability in phytoplankton due to thermal stratification and physical mixing, each process affecting the algal community in contrasting ways. The second factor was interpreted as reduction vs. oxidation processes. Positive correlation between stratification and water pumping by a drinking water plant indicated that human activities were not severe enough to break down the thermal stability of the reservoir and to cause a cyanobacterial bloom.

Research background: Since the introduction of the concept in 1972 Autopoiesis has enjoyed great popularity among academicians representing various fields of science. However, the number of studies devoted to the investigation of factors that have an impact on the formation of autopoietic economic structures is quite limited. This paper addresses the gap in scientific research on autopoiesis of economic structures in small open markets, specifically in the Baltic States.Purpose of the article: The paper aims to identify and evaluate factors that turn on self-organization mechanisms of autopoietic economic structures in the Baltic States, in particular in Latvia.Methods: Expert survey was used to identify the most important factors affecting the for-mation of meso-economic entities in the Baltic States. The factors’ assessments provided by seven experts were analyzed. Analytic Hierarchy Process (AHP) with fuzzy numbers was employed to process the data. Two different scales of evaluation (inverse linear and balanced) were used.Findings & Value added: The factors influencing the process of formation of business groups were evaluated by experts. Research results allow for making conclusions regarding the causes of the business integration, and impact of diversified integrated business structures on the country's business system in Central Europe.
