The role of cultural value dimensions in relational demography

The Malaysian public sector has undergone various transformations since the Independence. From its custodial role in the newly independent country, the public sector had changed and taken an active role in the country’s economic development. However, since 1980s onwards, the philosophy and techniques of New Public Management (NPM) have been implemented in Malaysia.This again transformed the public sector from being an engine of economic growth to become a facilitator to the private sector and service provider to the public. In line with NPM’s underlying belief of the superiority of businesslike practices, various contemporary management practices and philosophy were implemented in the Malaysian public sector. The implantation of private sector practices in the public sector was enhanced with the introduction a performance measurement system which utilises the use of key performance indicators in 2005. Thus, the purpose of this paper is to examine and analyse the current improvement programme within the wider public sector reform programmes in Malaysia. The issues and consequences of using key performance indicators in the public sector are discussed. To understand further the reasons and the push for reform, contextual descriptions of the various phases of public sector reform in Malaysia are also discussed in this paper

The Role of Cultural Value Dimensions In Relational Demography

This paper examines how cultural value dimensions affect processes related to social identity theory and relational demography. Gender differentiation, individualism/collectivism, and power distance are each positioned as important variables that have the potential to impact the level of salience for particular social identity characteristics. The value dimensions of uncertainty avoidance and long-term/short-term orientation are each positioned as contextual variables, moderating the relationships between demographic dissimilarity and outcomes related to bias and discrimination. The framework presented should have implications for future research in relational demography and assist managers in their attempt to understand individual differences in organisations.

Cosmic microwave background constraints on the duration and timing of reionization from the South Pole Telescope

The epoch of reionization is a milestone of cosmological structure formation, marking the birth of the first objects massive enough to yield large numbers of ionizing photons. The mechanism and timescale of reionization remain largely unknown. Measurements of the CMB Doppler effect from ionizing bubbles embedded in large-scale velocity streams (the patchy kinetic Sunyaev-Zel'dovich effect) can constrain the duration of reionization. When combined with large-scale CMB polarization measurements, the evolution of the ionized fraction can be inferred. Using new multi-frequency data from the South Pole Telescope (SPT), we show that the ionized fraction evolved relatively rapidly. For our basic foreground model, we find the kinetic Sunyaev-Zel'dovich power sourced by reionization at l=3000 to be <= 2.1 micro K^2 at 95% CL. Using reionization simulations, we translate this to a limit on the duration of reionization of Delta z <= 4.4 (95% CL). We find that this constraint depends on assumptions about the angular correlation between the thermal Sunyaev-Zel'dovich power and the cosmic infrared background (CIB). Introducing the degree of correlation as a free parameter, we find that the limits on kSZ power weaken to <= 4.9 micro K^2, implying Delta z <= 7.9 (95% CL). We combine the SPT constraint on the duration of reionization with the WMAP7 measurement of the integrated optical depth to probe the cosmic ionization history. We find that reionization ended with 95% CL at z > 7.2 under the assumption of no tSZ-CIB correlation, and z>5.8 when correlations are allowed. Improved constraints from the full SPT data set in conjunction with upcoming Herschel and Planck data should detect extended reionization at >95% CL provided Delta z >= 4.
