The Impact

In the EU, sheep bred for dairy and meat purposes are of low quality, their economic value is not even enough to cover shearing costs, and their wool is generally seen as a useless by-product of sheep farming, resulting in large illegal disposal or landfilling. In order to minimize environmental and health-related problems considering elemental compositions of discarded materials such as waste wool, there is a need to recycle and reuse waste materials to develop sustainable innovative technologies and transformation processes to achieve sustainable manufacturing. This study aims to examine the application of waste wool in biocomposite production with the help of a sustainable hydrolysis process without any chemicals and binding material. The impact of superheated water hydrolysis and mixing hydrolyzed wool fibers with kraft pulp on the performance of biocomposite was investigated and characterized using SEM, FTIR, tensile strength, DSC, TGA, and soil burial testing in comparison with 100% kraft pulp biocomposite. The superheated water hydrolysis process increases the hydrophilicity and homogeneity and contributes to increasing the speed of biodegradation. The biocomposite is entirely self-supporting, provides primary nutrients for soil nourishment, and is observed to be completely biodegradable when buried in the soil within 90 days. Among temperatures tested for superheated water hydrolysis of raw wool, 150 °C seems to be the most appropriate for the biocomposite preparation regarding physicochemical properties of wool and suitability for wool mixing with cellulose. The combination of a sustainable hydrolysis process and the use of waste wool in manufacturing an eco-friendly, biodegradable paper/biocomposite will open new potential opportunities for the utilization of waste wool in agricultural and packaging applications and minimize environmental impact.

The purpose of this work is to understand the impact of superheated water hydrolysis treatment on the chemical properties of wool, and compare it with a conventional method of alkaline hydrolysis. The effects of hydrolysis temperature and concentration of alkali on the properties of wool were investigated. Superheated water hydrolysis was carried out at the temperatures of 140℃ and 170℃, with a material to liquor ratio of 1:3 for 1 hour. In conventional alkaline hydrolysis, the experiments were carried out in the same conditions using potassium hydroxide (KOH) and calcium oxide (CaO) with a concentration in the range of 5%–15% on the fiber weight (o.w.f.). The effects of hydrolysis temperature and alkali concentrations on wool properties were checked using optical and scanning electron microscopy. It was observed that the hydrolyzates obtained in both cases contained low molecular weight proteins and amino acids. Both the hydrolysis processes resulted in degradation of the wool fibers. However, superheated steam hydrolysis is an environmentally friendly and less expensive process, as it is performed using water as a solvent. The wool hydrolyzates produced using superheated water hydrolysis could find a potential application in agriculture, such as fertilization, soil improvement and suchlike.

The Impact

The state of Tamil Nadu, India, is in the grips of a water crisis, with demand far outstripping supply. As the economy of the state grows, this crisis is going to become ever more serious. To date the focus of state water policy has been on trying to augment supplies, from within the state (even from desalinization) and from neighboring states. In addition, the water use is regulated in a way that does not encourage the highest value uses. International experience shows that supply-side measures must be complemented by demand-side measures and that practice must move away from fixed, command-and-control allocation policies towards flexible allocation mechanisms, which facilitate the voluntary movement of water from low to high-value uses. This study addresses the question of whether such a change in allocation policies is worth doing. It addresses this question by developing optimization models for each of the 17 river basins in Tamil Nadu (including an assessment of the economic value of water in different end-uses – agriculture, domestic and industry), then using an input–output model embedded in a social accounting matrix (SAM), to assess the impact of these changes on the state economy and on different rural and urban employment groups. The results suggest that a shift to a flexible water allocation system would bring major environmental, economic and social benefits to the state. Compared with the current “fixed sectoral allocation” policy, a flexible allocation policy would, in 2020, result in 15% less overall water used; 24% less water pumped from aquifers; 20% higher state income; with all strata, rich and poor, benefiting similarly, with one important exception, that of agricultural laborers.

This Community Service is a Community Partnership Program that was carried out by to partners of the Brown Sugar Cane Business Group in Latellang Village, Patimpeng District. The processing of sugar cane so far has been very simple, and some of the sugar cane businesses were out of business due to the consumption and need for brown sugar cane by the community, especially the Latellang and other villages, who are reluctant to consume brown sugar cane. This reluctance is caused by the aroma of brown sugar cane. Therefore, diversification of brown sugar cane products was carried out by processing brown sugar cane into Liquid sugar and Recengan sugar. The results of the PKM program were able to provide partners with increased knowledge of processing brown sugar cane into a diversified product that has high economic value and reduced the price of brown sugar cane from Rp. 10,000 per kilogram into products with 250 grams of brown sugar cane as raw material. 2-3 bottles of Liquid Sugar (250 ml plastic packaging) with a price of Rp.10,000 per bottle and produce 15 pieces of Recengan Sugar. Especially for Recengan sugar packaging, it is packaged in pouch containing 8 Recengan sugar ata a price of Rp.10,000. The impact will be revive the production of cane brown sugar to the Cane Brown Sugar Business Group partners, especially in Latellang Village.

Nowadays the main potential for growth comes from the ability to innovate and succeed with breakthrough ideas. However, despite growing importance of the subject matter, there are still no standard practices that would perform such a measurement and employ tendencies of human capital circulation. Various attempts have been made over recent years, but none have achieved general acceptance among experts in the business field. Although there is no universally accepted theory, each has its own strengths and weaknesses in the deriving approximate value of intellectual capital for various companies. In this work, we looked over some theories that have been suggested to estimate intellectual capital and analyzed data from Ukrainian IT companies in order to prove how important measurement of intellectual capital and human capital circulation trends to allow for much better representation of an organization’s competitive position. Additionally, the impact of intellectual capital on various Key Performance Indicators, such as Economic Value Added and Weighted Average Cost of Capital, was examined with supporting financial analysis performed. The paper concludes with an overview of methodological and managerial implications of the research, theoretical and practical limitations and possible improvements, and considerations for further research in the field of study.

Primary Forests

Large primary forest residuals can still be found in boreal landscapes. Their areas are however shrinking rapidly due to anthropogenic activities, in particular industrial-scale forestry. The impacts of logging activities on primary boreal forests may also strongly differ from those of wildfires, the dominant stand-replacing natural disturbance in these forests. Since industrial-scale forestry is driven by economic motives, there is a risk that stands of higher economic value will be primarily harvested, thus threatening habitats, and functions related to these forests. Hence, the objective of this study was to identify the main attributes differentiating burned and logged stands prior to disturbance in boreal forests. The study territory lies in the coniferous and closed-canopy boreal forest in Québec, Canada, where industrial-scale logging and wildfire are the two main stand-replacing disturbances. Based on Québec government inventories of primary forests, we identified 427 transects containing about 5.5 circular field plots/transect that were burned or logged shortly after being surveyed, between 1985 and 2016. Comparative analysis of the main structural and environmental attributes of these transects highlighted the strong divergence in the impact of fire and harvesting on primary boreal forests. Overall, logging activities mainly harvested forests with the highest economic value, while most burned stands were low to moderately productive or recently disturbed. These results raise concerns about the resistance and resilience of remnant primary forests within managed areas, particularly in a context of disturbance amplification due to climate change. Moreover, the majority of the stands studied were old-growth forests, characterized by a high ecological value but also highly threatened by anthropogenic disturbances. A loss in the diversity and functionality of primary forests, and particularly the old-growth forests, therefore adds to the current issues related to these ecosystems. Since 2013, the study area is under ecosystem-based management, which implies that there have been marked changes in forestry practices. Complementary research will be necessary to assess the capacity of ecosystem-based management to address the challenges identified in our study.

Research background: The modern goal of enterprises, value creation, is achieved through the concept of economic profit. Profit, as part of profit or loss, is one of the most important flows, pointing to how efficiently corporate capital is used in an entity (Coatney & Poliak, 2020). The article deals with the difference between accounting and economic profit, the selected form of economic profit - the EVA indicator. The economic value added (EVA) indicator is one of the best-known modern indicators of a company's performance (Siekelova et al., 2019). It shows whether the given entity increases its value or only earns for its economic survival. The benefit of this indicator is the valuation of equity and taking into account the risk. It is difficult to express the economic profit itself, therefore the article also addresses the issue of its calculation (Shah et al., 2016). The company needs to know its financial status and the direction it is heading, so we decided to calculate a selected form of economic profit. Purpose of the article: The company needs to know its financial status and the direction it is heading, so we decided to calculate a selected form of economic profit. When expressing the value of the economic value added indicator, it is also important to know the items and components of the calculation that have the strongest meaning and effect on the possible amount of the indicator. Given this, we decided to use a sensitivity analysis, which points to the effect of individual variables that participate in the construction of the EVA calculation. Methods: In this work, the methods of induction, deduction, and comparison were used to obtain a true picture of the subject issue. Methods of synthesis and analysis of the researched issues were also used. Findings & Value added: In the paper there is pointed out the intensity of the impact of individual variables that entered into the calculation of the economic value added indicator as a dominant indicator of concept of economic profit.

Virola surinamensis is a dioecious timber species of Amazonian floodplain forests. It is threatened by extinction and a priority species in the conservation program of genetic resources with high economic value for Brazil. The present study was aimed to assess the population structure of Virola surinamensis and the impact of logging in the estuary region of Brazilian Amazonia. Our data suggest that altering the dioecious population structure by logging likely creates the imbalance of male and female individuals in the population. New policies are needed to protect Virola trees with a special regard on reproductive matriarch trees.

Employees are one of the key resources involved in building of corporate reputation. The efficiency of employees is reflected in the corporate reputation and depends on the development of the employer brand. The concept of the employer brand is aimed at building the image of attractive employer in the labor market and implies providing functional, psychological and economic benefits for potential and current employees. The aim of this paper is to examine the interdependence of the employer brand dimensions and the corporate reputation of the observed hotels in the Republic of Serbia. The research involved the application of correlation analysis, regression analysis and non-parametric tests to check the differences between groups. In the paper are observed three dimensions of the employer brand: functional-economic value, social value and interest value. It is proved and the presence of a positive and statistically significant correlation between the dimensions of the employer brand and the corporate reputation of the observed hotels. Based on the processed data, the influence of the dimensions of the employer brand on the corporate reputation of the hotel has been proven, with the strongest influence on the social value and functional-economic value. Non-parametric tests did not reveal a statistically significant difference in the level of development of the employer's brand dimensions between different categories of hotels.

Purpose – This paper aims to investigate a guest’s subjective appraisal of a hotel’s green marketing program, or green equity, along with value, brand and relationship equities on guest loyalty. Design/methodology/approach – Study 1 presents three models to explicate the role of a luxury hotel’s green initiatives in influencing guest loyalty. By means of structural equation modeling, one model emerges with the best fit. Study 2 examines how tourists assign economic value to a hotel’s green programs. Findings – Green equity plays a significant role in customers’ overall assessment of a hotel’s marketing programs; however, the effect is weaker when compared with the other indicators, including a hotel’s value proposition, brand image and loyalty programs. Furthermore, the results reveal that tourists are willing to pay a price premium for a hotel’s green marketing programs. Research limitations/implications – The paper links green marketing to the customer equity model and clarifies the impact of green marketing programs on loyalty and profitability. However, the study was conducted among luxury hotel guests and tourists in Macau, a leading gambling destination; thus, these customers might not have been concerned with green marketing initiatives. Practical implications – The results show that green initiatives are beneficial as long as managers include these initiatives in their overall strategic marketing programs that also promote firm value propositions, brand images and reputation. Originality/value – The paper clarifies the role of green marketing programs in hospitality and shows how hotels can benefit from enhanced guest loyalty and decreased operational expenses by implementing green initiatives.
