Abstract

Purpose

Despite unanimity in the literature that eco-innovation (EI) leads to sustainable development, evidence remains limited on measuring EI efficiency with the Malmquist productivity index (MPI). In conventional data envelopment analysis (DEA) models, decision-making units (DMUs) are inclined to assign more favorable weights, even zero, to the inputs and outputs to maximize their own efficiency. This paper aims to overcome this shortcoming by developing a common set of weights (CSW).

Design/methodology/approach

Using goal programming, this study develops a CSW model to evaluate the EI efficiency of the organization for economic co-operation and development (OECD) countries and track their changes with MPI during 2010–2018.

Findings

Achieving a complete ranking of DMUs, findings show the higher discrimination power of the proposed CSW compared with the original DEA models. Furthermore, results reveal that Iceland, Latvia and Luxembourg are the only OECD countries that have incessantly improved their EI productivity (MPI > 1) from 2010 to 2018. On the other hand, Japan is the OECD country that has experienced the highest yearly EI efficiency during 2010–2018. This paper also found that Iceland has the highest MPI over 2010–2018.

Practical implications

More investment in environmental research and development (R&D) projects instead of generic R&D enables OECD members to realize more opportunities for sustainable development through minimizing energy use and environmental pollution in any form of waste and greenhouse gas emissions.

Originality/value

In addition to developing a novel common weights model for DEA-MPI to measure and evaluate the EI of OECD countries, this paper develops a CSW model by including the undesirable outputs for EI analysis.

Abstract

Purpose

The purpose of this paper is to discuss the challenges of assessment and management of psychotic symptoms in a background of intellectual disability (ID) and treatment-resistant epilepsy caused by a genetic syndrome.

Design/methodology/approach

Ring chromosome 20 [r(20)] syndrome is characterised by the triad of severe refractory epilepsy, mild to severe ID and behavioural problems. This paper describes the presentation of r(20) syndrome in a young woman with moderate ID and treatment-resistant epilepsy, who experiences psychotic symptoms at times of improved seizure control.

Findings

There are several diagnostic possibilities for such a presentation, including psychotic symptoms due to adverse effects of anti-epileptic medications and forced normalisation (alternating psychosis).

Originality/value

This paper advocates judicious use of antipsychotic medication to manage psychotic symptoms, as well as involvement of both patient and close family members throughout all stages of care. It is essential to strike a balance between control of epileptic seizures and psychiatric symptoms, providing an optimal benefit to the patients’ quality of life by meeting their complex needs through a multidisciplinary and multi-agency team input.

Abstract

Purpose

Universities play a central role in scientific development and progress in societies, so, the need for supporting new businesses in universities becomes very important that science and technology park-based incubators can meet it. The purpose of this paper is to prioritize the factors influencing strategic management of university business incubators (UBIs).

Design/methodology/approach

Present research prioritizes the factors influencing strategic management of incubators using analytic network process (ANP). The authors gathered data from UBIs affiliated with science and technology park of Guilan, located in city of Rasht (Iran) using the ANP questionnaire during year 2017.

Findings

Factors influencing strategic management of incubators comprised of four main criteria and 14 sub-criteria. The criteria and sub-criteria were ranked based on their importance. Results show that “talented managers” has the highest importance for strategic management of UBIs.

Originality/value

This study offers a novel analysis and contribution to the knowledge of ranking UBIs with a multi-criteria decision-making technique. Results of this research show the relative importance of criteria and sub-criteria, which contributes to further improvement of incubator management. University managers and incubator directors can utilize the findings for better resource allocation and aligning the strategies of incubators with macro strategies of the country.

Abstract

Purpose

The purpose of this paper is to investigate the potential or actual role of rural libraries in preserving indigenous knowledge (IK) of the rural residents in South Khorasan province.

Design/methodology/approach

The study, based on a qualitative research, was carried out by employing the grounded theory method. Data were collected by semi-structured interviews from the research sample population which included 20 rural males, 10 rural females, 8 librarians and 3 well-informed regional IK specialists. The validity of the research was confirmed by peer evaluation, compounded by detailed thorough explanations and external reviewers’ reaffirmations.

Findings

The rural residents of the South Khorasan villages across the province, after having realized the vitality of carrying out this project, were fully motivated and cooperative to provide indigenous knowledge. On the basis of the results from the rural libraries, due to being the solitary knowledge center in the area, these libraries could actively participate in preserving the knowledge and contribute toward the documentation of the indigenous knowledge. This required motivating librarians and increasing their professional, technical, research and verbal skills. The results of the study indicated that, even if the rural libraries of the South Khorasan province did not participate in documentation, preservation, and promotion of the IK and opt for the present form of non-participation, due to their inherent nature, they could become a focal point and play an indispensable role in achieving the objectives by aiding and leading the process at country level and become a focal point for the new generations of rural inhabitants to enlighten themselves and become fully aware of the value of the ancestral knowledge.

Originality/value

Hitherto, none of the researchers in Iran has covered the role of the libraries in general and rural libraries in particular in preserving the indigenous knowledge.

Abstract

Purpose

Conventional data envelopment analysis (DEA) models permit each decision-making unit (DMU) to assess its efficiency score with the most favorable weights. In other words, each DMU selects the best weighting schemes to obtain maximum efficiency for itself. Therefore, using different sets of weights leads to many different efficient DMUs, which makes comparing and ranking them on a similar basis impossible. Another issue is that often more than one DMU is evaluated as efficient because the selection of weights is flexible; therefore, all DMUs cannot be completely differentiated. The purpose of this paper is to development a common weight in dynamic network DEA with a goal programming approach.

Design/methodology/approach

In this paper, a goal programming approach has been proposed to generate common weights in dynamic network DEA. To validate the applicability of the proposed model, the data of 30 non-life insurance companies in Iran during 2013-2015 have been used for measuring their efficiency scores and ranking all of the companies.

Findings

Findings show that the proposed methodology is an effective and practical approach to measure the efficiency of DMUs with dynamic network structure.

Originality/value

The proposed model delivers more knowledge of the common weight approaches and improves the DEA theory and methodology. This model makes it possible to measure efficiency scores and compare all DMUs from multiple different standpoints. Further, this model allows one to not only calculate the overall efficiency of DMUs throughout the time period but also consider dynamic change of the time period efficiency and dynamic change of the divisional efficiency of DMUs.

Abstract

Purpose

This paper aims to study the features of microstructures and mechanical properties of the joints which were produced by transient liquid phase method. The difference between phases in bonding region identified through metallography pictures and applying hardness and shear strength tests.

Design/methodology/approach

The bonding process was carried out at a temperature of 300°C for time durations ranging from 15 to 120 min. The scanning electron microscopy equipped with energy dispersive spectroscopy system and optical microscopy were used to examine microstructural characteristics, and mechanical properties of the joints were studied by applying microhardness and shear tests. The shear tests were conducted by a shear fixture which was mounted on the tensile machine.

Findings

The intermetallic compounds of the Cu6Sn5 −η and the Cu3Sn-ε were formed simultaneously in the bonding interface. Although the η-phase, which exhibits scallop-shaped morphology, grows very quickly, upon completion of the isothermal solidification stage, it turns into the ε-phase. The hardness of the bonding interface is significantly higher than that of the substrate. The shear results show that once the bonding process is complete, brittle fracture occurs. Moreover, a greater decrease in strength was observed when the ε-phase is the only phase in the bonding region.

Originality/value

The hardness number of the η-phase is higher than that of the ε-phase. The hardness numbers of the η-phase and the ε-phase are 894 and 689 HV, respectively. The mean shear strength values of the samples that were bonded at 300 °C for 15, 60 and 120 min were 11.7, 9.5 and 5.4 MPa, respectively.

Abstract

Purpose

This paper aims to present a novel robust control method based on an adaptive PI controller (APIC) to compensate for different disturbances and unknown dynamics for multi-phase induction machines.

Design/methodology/approach

The gains of the APIC are adapted online according to the tracking error. Proposed APIC is accompanied with designed linear disturbance observer (LDO) to present robust behavior to machine parameter variations and fault disturbances.

Findings

The results show remarkable dynamic performance in both healthy and faulty conditions when the six-phase induction machine works under APIC and LDO schemes.

Originality/value

The proposed controller need not readjust current controllers for the post-fault condition. The developed Simulink model efficiency is confirmed through experimental tests.

Abstract

Purpose

The diagnosis and management of cancer in people with intellectual disabilities (PWIDs) are fraught with difficulties. The purpose of this paper is to present a case study to highlight these difficulties.

Design/methodology/approach

The present case analysis describes the presentation of a 56-year-old man with a profound intellectual disability, who developed recurrent chest infections and died as a result of obstructive pneumonitis.

Findings

Despite a presentation over several years and numerous chest X-rays demonstrating a consistent lung abnormality, it was only on postmortem examination that a right-sided lung carcinoma was detected.

Originality/value

The papers have provided an update on the topic in light of recent legislations and management strategies which need to be applied to clinical practice if any improvement is to happen in the care of PWID.

Abstract

States that advertisers on the World Wide Webb (WWW) rely on a traditional mass communication model, which may be inappropriate for electronic commerce. Sets out to explore how marketing could happen on the WWW. Explains the WWW, its origins, its phenomenal growth, and the opportunities it opens up for commercial transactions, particularly in the USA. Refers to literature which indicates that conventional marketing activities need to be revisited and turned into virtual marketing if there is to be any success in electronic commerce. Cites five phases in this evolutionary process. Focuses on interactivity between the consumer and the marketing organization, predicting that good marketing will be based on good conversation, customer satisfaction and consumer access to the company.

Abstract

Prevalence of hearing impairment is quite common in people with learning disabilities (double jeopardy). However, this debilitating co‐morbidity remains largely undetected by carers and professionals due to presence of additional disabilities and complex clinical presentation in this population on the one hand, and lack of specialist hearing impairment service provision and difficulty in accessing generic audiology services on the other hand. This article aims to provide practical guidance on assessment and management of hearing impairment in people with learning disabilities by offering a narrative review of available literature on gaps in service delivery.
