PurposeThe aim of the current study is to empirically assess the effects of organizational flexibility on project portfolio (PP) performance, with the mediating role of innovation and moderating effects of environmental dynamism (ED) and absorptive capability (AC).Design/methodology/approachData were collected from 173 manufacturing firms and analyzed using structural equation modeling (SEM) with the help of a partial least squares (PLS) approach.FindingsResults show that innovation partially mediates the relationship between organizational flexibility and PP performance. Furthermore, the moderating effect of ED between organizational flexibility and innovation was analyzed. Additionally, AC also observed as a moderator between innovation and PP performance.Originality/valueBased on the resource-based view, this study contributes to the literature by addressing the roles of innovation, ED and AC in the relationship between organizational flexibility and PP performance. Implications for managers also discussed in the end; for example, to be more competitive, they should incorporate flexibility into the firm to encourage innovation. It also emphasizes to select new innovative opportunities that correspondingly have effects on the PP performance.

Non-Invasive Glucose Monitoring devices useMultivariate Calibration (MC) methods to estimate glucose concentration in blood. The accuracy of methods depends on spectral data obtained from tongue-to-spectrometer interface. In this work we examine four widely used MC methods, they are: Classical Least Square (CLS), Inverse Least Square (ILS), Principal Component (PC) and Partial Least Square (PLS). We discuss the impact of factor selection on the prediction of response for first overtone transmission spectra collected across human tongues. Results are exposed for various Signal-toNoise Ratio (SNR) and different factor values. We explicitly tackle the issue of low SNR in tongue-tospectrometer interface. We show that CLS outperforms factor based regression techniques where SNR is as low as 30 dB. Our results are useful in calibration models that are used to predict vivo glycemia from human tongue spectra.

Purpose The purpose of this paper is to investigate the relationship between knowledge sharing and project portfolio success in Chinese construction firms. It also examines how and under what conditions knowledge sharing contributes to project portfolio success. Design/methodology/approach The authors collected questionnaire survey from 178 construction enterprises in China that manage project portfolio as a main form of their business. Hierarchical multiple regression was used to test the proposed framework. Findings The empirical results indicate that all three types of knowledge sharing (knowledge sharing within the project, knowledge sharing among projects and knowledge sharing within the organization) are positively related to project portfolio success. Portfolio management quality (PMQ) conduits the impact of knowledge sharing on project portfolio success. Furthermore, portfolio interdependency moderates the main effect. Originality/value This research is among the first to explicitly differentiate three types of knowledge sharing existing in project portfolios. Also, this research contributes to the literature on the antecedents of project portfolio success by showing the effect of knowledge sharing. Furthermore, this study empirically contributes to portfolio management research by clarifying the critical role of PMQ and portfolio interdependency in the mechanism of knowledge sharing and project portfolio success.

In recent years there has been an increase in the enrollment of Muslim international students in higher education institutions in China. This research provides a brief overview of the issues that international Muslim students face during their campus life, such as adopting a new culture, lack of understanding from the broader university community, poor cultural or religious-responsive education, lack of accommodation for religious practices, and social isolation. This qualitative study also highlights some information about the unique needs of the Muslim students on campus and identifies areas for improvement. To overcome these issues, specific practical suggestions are given to the university administration, faculty, and staff to meet the needs of Muslim students, not only academically, but also socially and culturally.
