Purpose The purpose of this paper is to empirically investigate the effects of knowledge management (KM) enablers on KM processes in research universities and testing the direct relation between KM processes and OP. This study also proposes to examine the mediating role of intellectual capital (IC) and innovation in the relationship between KM processes and performance of universities. Design/methodology/approach Using a sample of 217 academic and administrative personnel from research universities of Pakistan, the hypothesized relationships were tested through partial least squares structural equation modeling technique. Findings The results reveal that KM enablers have a significant impact on KM processes. The results also indicate that KM processes influence organizational performance (OP) directly and indirectly through innovation and IC. Practical implications Findings of this study reinforce the corporate experience of KM and suggest how administrators of research universities and higher educational institutions can promote innovation and IC, which in turn enhance OP. Originality/value Despite the augmented importance of KM in higher education institutions or research universities, there is a dearth of studies that investigate the interplay of KM, innovation, IC and OP. This is one of the earliest studies that not only empirically investigate the interaction of KM enablers, KM processes and performance of research universities but also shed insights into the existing literature by simultaneously investigating mediating role of IC and innovation in the underlying relationship.

Purpose Knowledge management in the public sector is relatively an ignored avenue of research and practice that has recently been given attention. Knowledge management initiatives in the public sector are now not limited to the developed countries anymore. The public sectors of various developing countries including Pakistan have developed knowledge management functions to address the problems of low organizational commitment (higher turnover rates) and knowledge-workers’ performance. Consequently, the purpose of this paper is to examine the mediation role of organizational commitment in the relationship between knowledge management practices and knowledge-worker performance. Design/methodology/approach The data were gathered from 341 knowledge workers of the public sector health department of Punjab Province, Pakistan, where knowledge management unit initiative has been taken. It was then analyzed using the structural equation modeling. Findings Organizational commitment partially mediates the relationship between knowledge management practices and knowledge-work performance. Practical implications The public sector policy makers are strongly advised to implement knowledge management units and practices in order to enhance knowledge-work performance as well as organizational commitment. Originality/value First, the model on the mediating role of organizational commitment has never been examined before. Second, the data collection from the public Health Department of Pakistan, a developing country, is relatively rare because the public sector knowledge management studies have mostly been conducted in developed countries. Finally, this study extends the literature on knowledge management in the public sector that is the developing theme in knowledge management discipline while adding knowledge management as a toolkit to enhance knowledge-workers’, organizational commitment and knowledge-work performance.

There is a growing interest in solid oxide fuel cells (SOFCs) technology among the researchers a promising power generation with high energy efficiency, inflated fuel flexibility, and low environmental impact compared to conventional power generation systems. SOFCs are devices in which the chemical energy is directly converted into electrical energy with negligible emission. SOFCs have low pollution characteristics, high efficiency (~ 60%), and possess expanded fuel selection with little environmental effects. A single cell component of SOFCs is consisting an anode, cathode and an electrolyte which are stacked layer by layer to produce higher amount of power. The dense ceramic electrolyte transporting O2− ions and fills the space between the electrodes material. Redox reaction occurred at the electrodes side in the presence of fuels. The operating temperatures of SOFCs of 600–1200 °C which produced heat as a byproduct and fast electro-catalytic activity while using nonprecious metals. Many ceramic materials have been investigated for SOFCs electrolyte. Yttria-stabilized zirconia (YSZ) material was extensively used as dense electrolyte in SOFCs technology. In this review, the article presents; overview of the SOFCs devices and their related materials and mostly reviewed newly available reported.

Detection of brain tumor using a segmentation based approach is critical in cases, where survival of a subject depends on an accurate and timely clinical diagnosis. Gliomas are the most commonly found tumors having irregular shape and ambiguous boundaries, making them one of the hardest tumors to detect. The automation of brain tumor segmentation remains a challenging problem mainly due to significant variations in its structure. An automated brain tumor segmentation algorithm using deep convolutional neural network (DCNN) is presented in this paper. A patch based approach along with an inception module is used for training the deep network by extracting two co-centric patches of different sizes from the input images. Recent developments in deep neural networks such as drop-out, batch normalization, non-linear activation and inception module are used to build a new ILinear nexus architecture.The module overcomes the over-fitting problem arising due to scarcity of data using drop-out regularizer. Images are normalized and bias field corrected in the pre-processing step and then extracted patches are passed through a DCNN, which assigns an output label to the central pixel of each patch. Morphological operators are used for post-processing to remove small false positives around the edges. A two-phase weighted training method is introduced and evaluated using BRATS 2013 and BRATS 2015 datasets, where it improves the performance parameters of state-of-the-art techniques under similar settings.

The literature on the knowledge management relatively ignores an important concept, the individual knowledge management engagement-the degree to which a knowledge worker is involved with the knowledge management-related activities. This concept is imperative for nurturing the productivity of knowledge workers, knowledge management architecture effectiveness, and innovation. Therefore, this study proposes the mediating role of knowledge-worker productivity between individual knowledge management engagement and innovation. The data

Purpose Nowadays in the competitive economy, the field of entrepreneurship and particularly female entrepreneurship is rapidly advancing, and its contribution to the economy is imperative. Consequently, the female business students’ factors and university support factors are imperative to nurture the entrepreneurial intentions, but the literature does not address them at large. Therefore, this study aims to examine the impact of proactive personality, entrepreneurial self-efficacy and perceived university support factors on female student’s entrepreneurial intentions. Design/methodology/approach The data from a total of 306 female students from the business schools of universities of Pakistan is collected through the personal physical-survey questionnaires. The data were then analyzed through Partial Least Square-Structural Equation Modelling (PLS-SEM) technique for results. Findings The results indicate that the proactive personality, entrepreneurial self-efficacy and university support factors are the significant predictors of entrepreneurial intentions of female students. Moreover, the results also support that entrepreneurial self-efficacy partially mediates the relationship between proactive personality and entrepreneurial intentions of female students. Originality/value To the best of authors’ knowledge, the study originality lies in the testing of university support factors and individual personality factors (entrepreneurial self-efficacy and proactive personality) as the predictors of entrepreneurial intentions. Moreover, the present study provides the useful insight for the policymakers in formulating, delivering and evaluating educational policies into the universities for female students.

A wearable noninvasive biosensor for in situ urea detection and quantification was developed using a ureaseimmobilized photonic interpenetrating polymer network (IPN urease ) film. The photonic IPN film was intertwined with solid-state cholesteric liquid crystals (CLC solid ) and a poly(acrylic acid) (PAA) network on a flexible poly(ethylene terephthalate) substrate adhered to a poly(dimethylsiloxane) (PDMS) chip that was fabricated using an aluminum mold. The presence of urea in the chemical matrix of human sweat red-shifted the reflected color of the photonic IPN urease film, and quantification was achieved by observing the wavelength at the photonic band gap (λ PBG ) with a limit of detection of 0.4 mM and a linear range of 0.9−50 mM. The color changes observed in the photonic IPN film were digitalized using the CIE 1931 xy coordinates on a cell phone image, thereby enabling fast, direct diagnosis via a downloadable app. This novel PDMS chip can be expanded for use with other biosensors.
