Internationalization of higher education： Challenges, strategies, policies and programs

In today＇s changing world, the idea of internationalization of higher education especially in developing countries has been deduced from globalization of education process. The international aspect of higher education is becoming increasingly important, composite, and confusing. The higher education has an effect on the society through policy-making, funding, and planning. The purpose of this paper is to analyze the meaning, definition, importance, necessity, and pre-requisites of internationalization of higher education. This paper also studies the programs and strategies of internationalization of higher education. Key challenges for the future direction of internationalization are identified in this paper.

Ionized Calcium Measurement in Serum and Plasma by Ion Selective Electrodes: Comparison of Measured and Calculated Parameters

To determine the concentration of ionized calcium (iCa) collected in lithium heparin and gel tubes and to correlate the measured iCa with calculated iCa. Anaerobic fasting blood samples were simultaneously collected from healthy laboratory workers in lithium-heparin and gel tubes. iCa, pH, total calcium (CaT), total protein and albumin were measured. Ionized Ca was calculated with albumin and globulin values using an appropriate formula. Mean iCa in gel tubes showed a positive constant bias of 0.08 mmol/L (p < 0.001) when compared to lithium heparin results. The mean pH of blood taken in lithium heparin and gel tubes was non-significant (p = 0.3). Measured iCa poorly correlated with CaT (r = 0.2, p = 0.1) and calculated iCa (r = 0.2, p = 0.2). To evaluate the calcium status direct measurement of iCa must be done rather than using the formulae for iCa determination. In addition serum is recommended as the choice of sample for iCa determination in comparison to plasma samples.     

Marketing graduate employability: understanding the tensions between institutional practice and external messaging

ABSTRACT

Do the narratives of employability constructed by higher education institutions for marketing purposes differ from the conceptualisation and/or the realisation of employability within those institutions? The study reported here drew on interviews with 16 senior academic and student support staff who were tasked with developing student employability at one of nine institutions in Australia, Canada and the UK. We employed Holmes’ conceptions of employability as possessional, positional or processual to analyse how the interviewees conceptualised employability and the presentation of employability on the institutional websites. We found that most institutions’ employability marketing narratives were inconsistent with the institutional practice reported by staff. We explain this tension in the context of two competing characterisations of higher education: a university-student transaction view; and a learning view. We emphasise the need for internal and external narratives to align and advocate the need for engagement in a constructive and critical dialogue involving all stakeholders.     

A programme-wide training framework to facilitate scientific communication skills development amongst biological sciences Masters students

In this article we describe the effectiveness of a programme-wide communication skills training framework incorporated within a one-year biological sciences taught Masters course designed to enhance the competency of students in communicating scientific research principally to a scientific audience. In one class we analysed the numerical marks achieved by students (N 61) for specific communication assignments completed at the start and at the end of the course. This was complemented by questionnaires administered to students at the beginning and at the end of the course to self-assess their competency and to elicit their views on the usefulness of the training received. We considered three questions: did students’ communication skills improve during the course; did the outcomes depend on the place of previous education (UK or non-UK); and how useful did students consider the learning and teaching activities to be? We show that the training improved students’ self-reported competency in most of the communication skills considered. Coursework marks for writing literature reviews improved during the course (p < 0.001). Those marks were marginally associated (that is, approaching statistical significance after Bonferroni correction) with the place of previous education (relatively high in UK students; p = 0.005). Coursework marks for writing research proposals did not change during the course (p = 0.361) but did depend on place of previous education (relatively high for UK students (p = 0.001). Although this small study’s intriguing results merit further investigation, our initial data supports the use of a programme-wide framework of the type presented here to facilitate communications skills development amongst biological science graduate students.     

Quantitative estimation of dust fall and smoke particles in Quetta Valley

INTRODUCTION Over the recent decades extensive research on atmospheric particles in urban environments was carried out. Most of the following papers refer to their authors’ contribution to air pollution and the effects on human health (Dzubay and Mamane, 1989; van Borm et al., 1989; 1990; Rojas et al., 1990; Paoletti et al., 1991; 1999; Al-Rajhi et al., 1996; McMurry et al., 1996; Querol et al., 1996; BéruBé et al., 1997; Esteve et al., 1997; Harrison et al., 1997; Zou and Hooper…     

Secure distributed Kalman filter using partially homomorphic encryption

In this paper, we present a secure distributed estimation strategy in networked systems. In particular, we consider distributed Kalman filtering as the estimation method and Paillier encryption, which is a partially homomorphic encryption scheme. The proposed strategy protects the confidentiality of the transmitted data within a network. Moreover, it also secures the state estimation computation process. To this end, all the algebraic calculations needed for state estimation in a distributed Kalman filter are performed over the encrypted data. As Paillier encryption only deals with integer data, in general, this, in turn, provides significant quantization error in the computation process associated with the Kalman filter. However, the proposed estimation approach handles quantized data in an efficient way. We provide an optimality and convergence analysis of our proposed method. It is shown that state estimation and a covariance matrix associated with the proposed method remain with a certain small radius of those of a conventional centralized Kalman filter. Simulation results are given to further demonstrate the effectiveness of the proposed scheme.
