by Johnson Ojiyovwi Okorhi, Joe E. Amadi‐Echendu, Helen Olubunmi Aderemi, Roland Uhunmwangho, Osita Benedict Agbatah
Abstract: Nigeria still considers Waste Electrical and Electronic Equipment (WEEE) problem as more of socio-economic benefits rather than long-term human and environmental impacts. The study assessed the socio-economic factors affecting the trend of WEEE generation and handling in South Eastern Nigeria. The research concept identified key strategic aspects relative to socio-economic assessment of WEEE management. It used investigative approach through questionnaire administration. 20 local government areas were purposively selected from 5 mutually exclusive strata. Data from 201 respondents were analyzed using linear multiple regression and percentage. Results revealed that monetary provisions and public participation does not have significant relationship with WEEE generation and collection. The study revealed that the factors determined as affecting the trend of WEEE generation and collection cut across cheaper pricing of WEEE, availability of WEEE, quality/superiority of E.o.L EEE to newer ones, durability of device, low income consumers and the accessibility of end-users to WEEE.
Keywords: Waste Electrical and Electronic Equipment (WEEE); Socio-economic Assessment; South Eastern Nigeria; WEEE Framework.
Numerical Investigations on Feasibility of Surfactant Enhanced Remediation of Polycyclic Aromatic Hydrocarbonc in an Unsaturated Subsurface System beneath an Onshore Surface Spill Site
by VASUDEVAN MANGOTTIRI, BERLIN MOHANDHAS, MOHANASUNDARAM S, SURESH KUMAR GOVINDARAJAN, INDUMATHI NAMBI
Abstract: The adaptability of in situ remediation techniques for low soluble fractions in petroleum products such as Polycyclic Aromatic Hydrocarbon (PAH) is generally constrained due to their limited bio-availability owing to hydrophobicity. In the present study, a numerical model is developed to evaluate the effect of unsaturated hydraulic properties, equilibrium chemical partitioning as well as coupled reactions on the fate and transport of a typical PAH (phenanthrene) originating from a surface spill. Simulation of surfactant enhanced remediation using a non-ionic surfactant (Triton N-101) resulted in significant modifications in unsaturated hydraulic properties. Presence of natural organic matter (adsorption partitioning coefficient of 8.97

Interactive learning and technology transfer in wind energy. Dynamics and policy implications
by Pedro Varela-Vázquez, María Del Carmen Sánchez-Carreira
Abstract: Technology transfer and interactive learning are two key mechanisms to upgrade wind sectors in peripheral regions. Interactive learning involves bidirectional knowledge flows with beneficial outcomes for participants and the overall sector through a closed interaction within value chains. The main aim of this paper is to analyse the main features, drivers and outcomes of interactive learning in peripheral wind sector, as well as its coexistence with technology transfer schemes. For this purpose, two industrial partnerships are analysed in the Galician wind sector (Spain). The methodology is based on interviews with the main stakeholders involved in the partnerships. Empirical evidences underline supply-base capabilities and regional bidding procedures as key drivers of partnerships and the beneficial outcomes for the auxiliary industry of reciprocal technology learning process. Likewise, technology learning process could lead to diversifying firm core activities and makiing easier autonomous internalisation strategies.
Keywords: interactive learning; technology transfer; wind energy; policy implications; case-study; technology learning; Galicia.
Presence of tetracycline-resistant genes in manures from different-size farms situated close to Kazan (Russia)
by Natalya Danilova, Svetlana Selivanovskaya, Anil Kumar Sharma, Galitskaya Polina
Abstract: Antibiotic resistance is currently one of the most serious medical and environmental problems. In this study, the level of tetracycline resistant-gene contamination of the manures of different size farms that provide meat for Kazan (Russia) was investigated. A polymerase chain reaction (PCR) with specific primers for tet(A), tet(B), tet(C), tet(E), tet(M), tet(O), tet(S), tet(X) and subsequent electrophoresis was used to reveal the level of pollution. It was found that all 16 samples investigated contained at least one resistant gene. The genes tet(M), tet(O), tet(S), responsible for encoding ribosome protection, and tet(X), which encodes antibiotic decomposition, were the most abundant. No correlation was found between the farm size and the level of antibiotic resistant-gene pollution.
Keywords: Antibiotics; tetracycline; antibiotic-resistant genes; tetracycline-resistant genes; manures; manure fertilization; polymerase-chain reaction.
A consumption-based, regional input-output analysis of greenhouse gas emissions and the Carbon Regional Index
by Bas Straatman, Britta Boyd, Diana Mangalagiu, Peter Rathje, Christian Eriksen Rathje
Abstract: This paper presents a consumption-based method accounting for greenhouse gas emissions at regional level based on a multi-region input-output model. The method is based on regional consumption and includes imports and exports of emissions, factual emission developments, green investments as well as low carbon development policies. We comparatively analyse three regional case studies in Denmark and show how regional initiatives implemented to reduce emissions are translated into easy to access input-output parameter changes and how the method transparently assesses the impact of various long-term regional climate plans on emissions. For the comparative analysis we further develop a Carbon Regional Index (CRI), which delineates five key dimensions that define past, current and planned regional and embedded emissions. The method can form a basis for regional climate policies, promote the export of solutions from one region to another and enable policy-makers to observe good practices and test them at regional level before potential implementation on a larger scale.
Keywords: regional input-output analysis; carbon footprint; emissions import and export; regional comparison; carbon regional index; comparative benchmarking; DenmarkEngagement.
An Evaluation of Changes in Opinion from an Expert Workshop on Turbidity in Drinking Water Supplies and Acute Gastrointestinal Illness
by Arjita Rai, Patrick Gurian, Michelle Kondo, Issa Zakeri, Lucy Robinson, Anneclaire De Roos
Abstract: Over the past two decades a series of epidemiological studies have found associations between turbidity in drinking water supplies and acute gastrointestinal illness. The methods used in these studies, and the implications for drinking water supplies have been controversial. This research effort sought to critically evaluate these epidemiological studies through the preparation of a literature review and convening of an expert workshop. The research team prepared a literature review and circulated it to subject matter experts from a variety of disciplines and institutions. A set of issues identified during the literature review were discussed at a one-day workshop. Pre- and post-workshop surveys were conducted to assess any changes in opinion occurring after the workshop. Differences between pre- and post-survey responses were small, though shifted toward less favorable views of the studies. Pre- and post-survey means differed significantly regarding whether studies suggest more should be done to ensure U.S. drinking water quality. Responses shifted from weak agreement to weak disagreement with the statement that more should be done. Responses differed significantly by affiliation (academic institution, consulting, utility, and other) for three questions, by discipline (engineer, epidemiologist, other public health, statistician, and other) for one question, and by role in the study (research team, project advisory committee, and invited expert) for four questions. The research team consistently had the most favorable views of the studies compared to other participants. The survey results indicate that the workshop did not produce consensus among the participants. The survey provided a means of documenting that opinions expressed in the workshops discourse were not necessarily shared by all attendees.
Keywords: turbidity; drinking water; acute gastrointestinal illness; expert workshop; survey research.

Antecedents of Consumer Environmental Attitude and Intention to Purchase Green Products: Moderating Role of Perceived Product Necessity
by Chirag Malik, Neeraj Singhal, Surendra Tiwari
Abstract: With the increasing environmental problems, companies have started realizing their moral and ethical duties and gradually adopting sustainable business practices. The challenging task of communicating with the consumers with varied attitude towards the environment can be undertaken by understanding the factors influencing environmental attitude. This paper aims at identifying the antecedents of consumer environmental attitude and studying its relationship with the green purchase intention. Another objective of this paper is to find out the moderating effect of perceived product necessity on the relationship of consumer environmental attitude and intention to purchase green product. A conceptual model has been proposed and tested using confirmatory factor analysis and SEM. From a dataset of 729 Indian consumers, it has been found that four antecedents; environmental knowledge, environmental concern, interpersonal influence and collectivism are positively related to consumer environmental attitude which is further positively related to intention to purchase green product. It has also been found that perceived product necessity does not moderate the relationship between environmental attitude and green purchase intention.
Keywords: Consumer environmental attitude; environmental knowledge; environmental concern; collectivism; individualism; green purchase intention; perceived product necessity; structural equation modeling; green consumers.

by Mani Bansal, Anil Vij, Ruchi Nayyar
Abstract: Although organizational learning theory and practice has been studied by the practitioners and scholars over the past several years, there is much to be explored regarding interactions between variables related to organizational learning. Learning starts from individuals and ultimately forms the basis of organizational learning. In the present paper, interrelationship of variables related to effective organisational learning has been studied using Interpretive Structural Modelling. The model aims to identify the strategic and performance variables so that their role dominance can be identified. Further these variables have been categorized according to their driving power and dependence.
Keywords: Organizational Learning; Interpretive Structural Modelling Technique.
AN EMPIRICAL STUDY OF WORK-LIFE BALANCE OF PUBLIC SECTOR EMPLOYEES
by Padmini Jayagopal
Abstract: Work-life balance has turned into an imperative issue in the twenty-first century. Work and family life are two sides of an indistinguishable coin from both are interconnected and meddle with each other. Expanded work requests meddle with family life, and then again, family requests meddle with the work-life of employees. In this way, clashes happen, which adversely influence an employees performance at work and also at home. Taking a gander at the pattern, organisations have progressively begun to take a dynamic enthusiasm for executing rehearses that empower employees to adapt to the work-life balance issues. The review endeavored to investigate the work-life balance practices of chosen public sector undertaking. The finding proposed that public sector undertaking in India have understood that work-life balance practices are pivotal for organizational performance.
