Globalization or Glocalization? Higher Education Reforms in Singapore

Globalization and the evolution of the knowledge‐based economy have caused dramatic changes to the character and functions of higher education in most countries around the world. However, the impacts of globalization on universities are not uniform though business‐like practices have been adopted to cope with competition in the global marketplace. The pressure for restructuring and reforming higher education is mainly derived from growing expectations and demands of different stakeholders in society. In recent years, widespread concerns over widened access, funding, accountability, quality, and managerial efficiency are perceived as the prominent global trends related to university education. Because of the divergent political, social, economic, cultural and historical backgrounds, national/local governments may adopt similar strategies in response to pressures generated from globalization. Nonetheless, through a close scrutiny of the ways that national policies are made, we may find that governments around the globe, particularly in East Asia, have tried to make use of the globalization discourse to address/justify the local policy/political agendas. This paper aims to examine the latest higher education reform initiatives proposed by the Singapore Government, with particular reference to reflect upon how the Singapore Government reforms its university systems in the context of globalization. It is argued that the latest comprehensive review of public university governance and funding brings about a changing role of the government in the regulation, finance and provision of higher education in Singapore and eventually alters the state‐university relationship.     

From natural numbers to numbers and curves in nature - II

In this second part of the article we discuss how simple growth models based on Fibbonachi numbers, golden section, logarithmic spirals, etc. can explain frequently occuring numbers and curves in living objects. Such mathematical modelling techniques are becoming quite popular in the study of pattern formation in nature.     

Grade retention: Current decision‐making practices and involvement of school psychologists working in public schools

Research examining student outcomes (e.g., achievement, adjustment) after grade retention reveals that it does not result in long‐term improvements for students; however, grade retention continues to be used as an intervention. The purpose of this study was to examine retention decision‐making practices, as well as school psychologists' knowledge, beliefs, and opinions regarding retention. Actual and ideal roles of school psychologists in grade retention decisions were also examined. Participants included 250 school psychologists randomly selected from the membership of the National Association of School Psychologists. Results revealed that the decision to retain is a subjective one, typically made by a team. Responding school psychologists did not support retention and found the research moderately applicable to practice. However, most school psychologists indicated that they were not centrally involved in decision making. Findings also revealed a desire among school psychologists for increased involvement in developing and/or implementing programs aimed at improving performance and consulting on the effects of retention. © 2009 Wiley Periodicals, Inc.     

Determinants of Malaysian adult learners＇ distance learning

This study attempts to identify the factors perceived to be important in choosing an Institution of Higher Learning （IHL） for distance learning. One thousand five hundred questionnaires were distributed to the first year students in the social sciences distance learning programs and 980 valid responses were received of Malaysian public university. The results show that the top three factors influencing their preferred institution are qualification recognition IHL, future career advancement, and personal satisfaction. The results of this study provide insights to the IHL, employers and academics on the nature and relative importance of the factors perceived important for adult learners in the selection of their preferred IHL.     

Learning to observe: using video to improve preservice mathematics teachers’ ability to notice

Video has assumed an increasingly prominent role in teacher education, particularly in the form of the viewing of videotaped class lessons by preservice teachers. Yet there is little research that confirms whether preservice teachers attend to the aspects of the video(s) that teacher educators anticipate or desire. This article explores this issue and reports on the impact of video viewing as a means to improve teachers’ ability to be observers of classroom practice. We utilized a pre- and post-test design to measure the quantity and type of classroom events that preservice mathematics teachers noticed before and after a teaching methods course where improving observation skills was an explicit goal. The results of the pre-assessment suggest that preservice teachers generally do not enter teaching methods courses with well-developed observation skills. The post-assessment indicates that the course led to significant increases in preservice teachers’ observation skills, particularly in teachers’ ability to notice features of the classroom environment, mathematical content of a lesson, and teacher and student communication during a lesson.

Predicting Suicide Risks Among Outpatient Adolescents Using the Family Environment Scale: Implications for Practice and Research

This study was designed to identify characteristics of family functioning that relate to suicide potential in an outpatient adolescent population. Participants included 51 adolescents between the ages of 14 and 18 who were involved in outpatient counselling. The Family Environment Scale and the Suicide Probability Scale were used to assess adolescents’ perception of family social climate and degree of suicide risk respectively. Results revealed significant correlations between suicide risk and family systems characterized by heightened conflict and lower levels of cohesion, independence, and organization. A stepwise multiple regression analysis suggested that organization (related to clarity and structure in family activities and responsibilities) was the strongest predictor of suicide risk. Implications for research and practice are considered.     

Transport and shear in a microfluidic membrane bilayer device for cell culture

Microfluidic devices have been established as useful platforms for cell culture for a broad range of applications, but challenges associated with controlling gradients of oxygen and other soluble factors and hemodynamic shear forces in small, confined channels have emerged. For instance, simple microfluidic constructs comprising a single cell culture compartment in a dynamic flow condition must handle tradeoffs between sustaining oxygen delivery and limiting hemodynamic shear forces imparted to the cells. These tradeoffs present significant difficulties in the culture of mesenchymal stem cells (MSCs), where shear is known to regulate signaling, proliferation, and expression. Several approaches designed to shield cells in microfluidic devices from excessive shear while maintaining sufficient oxygen concentrations and transport have been reported. Here we present the relationship between oxygen transport and shear in a "membrane bilayer" microfluidic device, in which soluble factors are delivered to a cell population by means of flow through a proximate channel separated from the culture channel by a membrane. We present an analytical model that describes the characteristics of this device and its ability to independently modulate oxygen delivery and hemodynamic shear imparted to the cultured cells. This bilayer configuration provides a more uniform oxygen concentration profile that is possible in a single-channel system, and it enables independent tuning of oxygen transport and shear parameters to meet requirements for MSCs and other cells known to be sensitive to hemodynamic shear stresses.     

Effect of seasonality on the dynamical behavior of an ecological system with impulsive control strategy

In this paper, on the basis of the theories and methods of ecology and ordinary differential equation, an ecological model consisting of two preys and one predator with impulsive control strategy and seasonal effects is established. Conditions which guarantee the global asymptotical stability of the prey-eradication periodic solution are obtained using the theory of impulsive equations, small amplitude perturbation skills, and comparison techniques. Further, the influences of the impulsive perturbation and seasonal effects on the inherent oscillation are studied numerically. These show to be consistent with the theoretical analysis and rich complex population dynamics, such as species extinction and permanence. Moreover, the population dynamical behavior of the model is demonstrated by the computed largest Lyapunov exponent. By investigating the strange attractors through their computed Fourier spectra, we know that seasonality has a profound effect on the population dynamical behavior. All these results are expected to be of use in the study of dynamic complexity of ecosystems.
