Purpose – The present study involved the development of a value-added comminution process for different recycled meat processing by-products such as bones for management of waste products. The paper aims to discuss these issues. Design/methodology/approach – An indigenous cryo-grinding system was developed and pilot scale comminution tests were carried out on goat and hen bones under different temperature conditions ranging between −15°C and −40°C and sample pre-conditioning adopting liquid nitrogen as a grinding medium. Findings – Cryo comminution produces finer, uniform particle sizes, increased specific surface area per unit mass with lesser specific energy consumption in comparison to room temperature comminution. Breakage behavior studies showed that hardness (609-685 MPa) and brittleness (24-29 m−1/2) and strain energy decreased (3.1-1.1 N-m) as the temperature was lowered. Weight mean diameter, specific energy consumption under ambient and cryogenic conditions, respectively, were 125 and 80 μm, 1,303 and 1,108 kJ/kg. The process developed attempts to eliminate environmental pollution by reducing food wastes generated and incorporates value to waste products. Originality/value – A value-added comminution process for meat processing by-products such as bones was developed to reduce food wastes generated as well as environmental pollution. The process aims to improve public health stressing the importance of recycling through the management of food waste products. Public and private organizations can act as profit centers generating significant revenue and employment by adopting the process.

Purpose – The purpose of this paper is to discuss the challenges and obstacles encountered in the implementation of a mentoring program for Master of Business Administration (MBA) students at the University of South Australia (UniSA) Business School. The paper starts with an exploration into the need for a mentoring program, the trial and subsequent four years of implementation. The paper also explores the network model of mentoring and the reasons why this, rather than a more traditional model, was chosen for the program’s implementation. Design/methodology/approach – This exploratory case study uses data from over 600 students and their alumni mentors over a five-year period to evaluate and improve the program as well as cultivating a critical community of adult learners. Findings – Feedback from students indicates that the mentoring program is regarded by most as a value-added feature of their early learning as it offers support, if and when it is required, from those who have been there before. Research limitations/implications – Results are limited to one institution. However, as research into mentoring for higher education students is thin on the ground, this study contributes to our understanding of the positive impacts of mentoring on student success. Practical implications – This paper emphasizes the importance of business leaders giving back to their alma mater through mentoring current MBA students. It shows how mentoring can support learning and management development. Originality/value – This is an original study which explores ways to increase the learning of higher education students for positive social outcomes.

Purpose This study aims to explore the dynamics enabling strategic account management (SAM) to function as a value co-creation selling model in the pharmaceutical industry. Design/methodology/approach Using an inductive qualitative research design, data are collected within 11 industry customers in Canada. This work focuses on hospitals as strategic accounts of pharmaceutical companies, exploring SAM value co-creation in the “hospital-pharmaceutical company” relationship. Findings The findings suggest the presence of two key dimensions that can enable a value co-creation SAM model in the hospital-pharmaceutical relationship: “customer-tailored value-added initiatives” and “relationship enhancers”. Customer-tailored value-added initiatives explain the activities that are central to the hospital-pharmaceutical company relationship and can lead to the provision of value added that is unique to the hospital. Relationship enhancers explain the activities that can help strengthen hospital-pharmaceutical company relations in the pursuit of enhanced value-added interactions between the two parties. The research demonstrates a cyclical relationship between “customer-tailored value-added initiatives” and “relationship enhancers”, leading to value co-creation through a SAM model. Practical implications The study informs pharmaceutical industry practitioners on how to improve their value proposition through new, more sustainable selling practices. It offers information on implementing a value co-creation SAM model, which can enable pharmaceutical companies to sustain long-lasting value-added relationships with key accounts such as hospitals. Originality/value The study contributes to the field of SAM by conceptualizing SAM as a value co-creation system. It introduces new knowledge in pharmaceutical marketing by offering empirical insight on the applicability and use of SAM in the hospital-pharmaceutical company dyad.

Purpose The purpose of this study is to explore the impact of Wi-Fi service on the millennial generation’s loyalty to restaurants. Additionally, this study examines the impact of Wi-Fi service on three different types of restaurants (coffee shops, fast-food restaurants and casual dining restaurants). Furthermore, this study examines the similarities and differences that exist cross-culturally between Americans and Koreans. Design/methodology/approach A total number of 480 questionnaires were collected to empirically test the study model. A factor analysis that used a principal components analysis with varimax rotation was performed to condense the loyalty items into a few underlying constructs, and the Cronbach’s alpha was checked to test for reliability. A multiple regression analysis and t-test were performed to test the study hypotheses. Findings The results show that Wi-Fi service has a significant impact on millennials’ loyalty behavior on all three types of restaurants in this study. However, the differences between Americans and Koreans on how they perceive the Wi-Fi services turned out to be significant only for coffee shops. Research limitations/implications The authors used a non-probability convenience sampling method for data collection. The findings cannot be generalized to other types of restaurants, such as fine dining and luxury restaurants. Although the results indicate a positive relation between Wi-Fi usage and a customer’s loyalty, loyalty is a multifaceted concept where a variety of factors, such as frequency or convenience can have an impact. Practical implications The findings should encourage marketers in the restaurant industry to use Wi-Fi as a value-added service for their customers. Originality/value There are limited studies on how significant Wi-Fi service is for the hospitality industry, and in particular, for restaurants. This study builds on the scholarship of Cobanoglu et al. (2012) on the value of the customer loyalty by providing new insights into customers’ views on Wi-Fi service in the restaurant industry.

Purpose – The purpose of this paper is to extricate value-added exports in information and communications technology (ICT) industry earned by Taiwan and Korea. Additionally, the authors decompose Taiwan and Korea’s gross exports into various meaningful components. Design/methodology/approach – The authors use the inter-country input-output (ICIO) table which endows with cost structures of industries as well as trade information, facilitating in keeping track of the flow of products and value-added. The ICIO table used in this paper comes from the World Input-Output Database. The authors also use the way Wang et al. (2013) decomposed the intermediate goods exports into various components to provide further insights. Findings – The empirical results indicate that Taiwan and Korea’s ICT export to the world shrink by 47.8 and 40.9 percent when the trades are measured in value-added terms. Taiwan and Korea’s ICT export will also decrease by 75.1 and 57.8 percent. From the viewpoint of value added in trade, the share of value added embodied in Taiwan and Korea’s gross ICT exports continued to decrease and reached 24.9 and 42.2 percent in 2011, while the components of pure double counted terms kept growing in recent years. Originality/value – With global value chains flourishing in recent years, conventional trade statistics not only fails to highlight the vertical specialization among different countries, but also distorts the measurement of a country’s competitiveness. This paper extricates value-added exports in ICT industry earned by Taiwan and Korea and bring into focus the importance of trade in value added.

Purpose The continuous increase in the discharges of carbon emissions (CO2) in the global atmosphere and the likely negative consequences of this practice on the atmosphere draw the attention of researchers and policymakers to argue on the causes and perpetrators of CO2 emissions. This paper aims to examine the impacts of hydropower consumption, FDI and manufacturing performance on CO2 emissions in the Association of southeast Asian nations (ASEAN)-4 countries. Design/methodology/approach The study uses the data on variables, such as hydro-power consumption, FDI, manufacturing value added and CO2 emissions spanning the period 1980–2015. Autoregressive Distributive Lag Bound test approach was used to assess the relationships among the variables. Findings The long run estimation of elasticities for all the countries indicates that the coefficient of hydro power consumption was found to be significantly related to CO2 emissions only in Malaysia. Additionally, the coefficients manufacturing performance were found to be significant in influence the amount of CO2 emission in all the ASEAN-4 countries. Furthermore, the coefficients of FDI inflows were found to be significant in explaining CO2 emissions in Malaysia and the Philippines, respectively. In the short run, the estimated results show that all the variables were found to be significant in explaining CO2 emissions in the countries under study. Research limitations/implications Singapore is excluded from the ASEAN-4 due to insufficient data on hydro energy consumption. Practical implications The study recommends that as Hydro power energy is a clean source of renewable electricity. Its consumption indicates a negative relationship with CO2 emissions. The countries should emphasize more on the use of hydro source of energy than the other sources which increase the rate of CO2 emissions in the atmosphere. Originality/value As most of the relevant previous studies did not consider the simultaneous impact of hydro energy consumption, FDI and manufacturing value added on CO2 emissions in the ASEAN-4, this study is an important contribution to the existing relevant literature.

Bioconversion is the process whereby nutrients are recovered from organic waste products, often by flies, to produce value-added products such as protein for animal feed and lipids for biodiesel production. Currently, research and industry focus on a select few fly species for use in bioconversion that are generalists in their feeding behaviour, the black soldier fly, Hermetia illucens L., and the housefly, Musca domestica L. More investigation is needed on species of flies that are more suited to underutilised waste streams, including meat processing waste. Species of flies that breed in carrion, such as blowflies (Calliphoridae) and flesh flies (Sarcophagidae) can be used to reduce meat processing waste and produce a valuable source of protein. In this review, we propose more investigation and use of a wider range of fly species for bioconversion of organic waste. Four blowfly species are recommended for use in the bioconversion of meat processing waste or a mixture of manure waste and meat processing waste. Chrysomya chloropyga (Wiedemann) is a large mammal carcass specialist and has been found to be effective at recovering nutrients from abattoir waste within four days and producing large larvae in the process. Chrysomya putoria (Wiedemann) and Chrysomya megacephala (Wiedemann) naturally breed in carrion and faeces, are associated with pit latrines and respond well under mass rearing conditions, with high egg production. These species would be recommended for a large-scale bioconversion facility that receives mixed waste streams including manure and animal remains. Lucilia sericata is known to produce antimicrobial compounds that assist in wound healing and has been frequently bred and studied and responds well to lab and mass rearing conditions. We recognise the potential obstacles to using alternative species in industrial-scale bioconversion facilities and pose future directions for research to overcome these challenges.

Purpose The framework of the International Integrated Reporting Council (IIRC) is principles-based and does not provide specific key performance indicators (KPIs) for integrated thinking and reporting. Therefore, the purpose of this paper is to propose KPIs for integrated reporting which decipher a firm’s sustainability through empirical analysis. Design/methodology/approach As a proxy of firms’ sustainability, the authors focus on firms that have survived for more than 100 years and that have already achieved sustainability, and analyze these firms to reveal the financial features that distinguish sustainable firms from the other firms. Findings The study found two distinguishing facts: the value added that is distributed to stakeholders other than shareholders is significantly larger, and the stability of profitability and the profitability itself are significantly higher in sustainable firms. Practical implications The study proposes a value-added distribution and the stability of profitability as sustainability KPIs for integrated reporting. Originality/value First, this study provides the first evidence that value added distribution and the stability of profitability distinguish a firm’s sustainability. Second, it provides a new perspective in the search for sustainability KPIs. Third, as the empirical data consist of all listed firms in 136 countries, the results should be robust and general.
