Differences between supplier development programme of foreign and local Malaysian automotive suppliers

Research into supplier development has raised issues on the buyer’s relationship with the supplier.A buyer with collaborative relationship would have more interest in supplier development.From the viewpoint of the suppliers, buyers who provided assistance could help the suppliers in developing their capability, a situation that might be particularly relevant in developing and emerging countries. The automotive manufacturers have implemented supplier development programmes for their suppliers, both in developed and developing countries.This raises a question on supplier development programmes in developing countries: How do supplier development programmes differ between a local (Malaysian) supplier and a foreign (non-Malaysian) supplier for Malaysian automakers (buyers)? In this research, interviews were conducted at three supplier organisations, of which one was Australian and two were Malaysian, where all three were suppliers for a Malaysian automaker.This study found that the Malaysian and Australian suppliers differed in supplier categories, customisation versus standardised products and buyer involvement.The study suggests that buyer differences with regard to supplier relationship, supplier commitment, type of product and size of supplier organisation play a role in supplier development

Technical Change, Technical Efficiency, and Their Impact on Input Demand in the Agricultural and Manufacturing Sectors of Pakistan

Technical change has been considered as one of the most important determinants of economic growth. In developed economies, a proportionately higher percentage of GDP growth is attributable to technological progress and technical efficiency. However, technical change in developing countries is in its early stages and increased use of factor inputs is still the dominant source of economic growth. An attempt has been made in this paper to analyse technological progress and technical efficiency and their contribution to economic growth along with other factors of production by using more efficient methods in the manufacturing and agriculture sectors of Pakistan. There are a few studies on technological growth and technical efficiency change in Pakistan but they suffer from certain limitations. Most of them use the terms of technical change and productivity synonymously. Further, all of them use Hicks’s formula of neutral technical change and assume that technical change is happening at a constant rate. We have attempted to measure technical change, technical efficiency, and productivity in the form of the Hicks neutral technical change as well as in the form of variable and continuous and discrete technical change. Besides, this paper also analyses the impact of technical change on input demand (i.e., its impact on labour and capital demand) and examines the issue of technical change being either labour-saving or capital-saving. We found that technical change was taking place at a continuous and variable rate. The major contributor to the growth of output and value-added in both sectors was capital, contributing over 50 percent. Labour share was about 20 percent in the agriculture sector and about 10 percent in the manufacturing sector. Technical change share was very significant in manufacturing but not so in agriculture. The manufacturing sector in Pakistan has grown at an annual rate of about 6 percent during 1970s and at 8.7 percent during 1980s, and its share in GDP has increased from 16.5 percent to about 19 percent, but it has failed to generate new employment opportunities for the labour force. The employment growth rate is only about 2 percent.

Entrepreneurial characteristics of indigenous housing developers: the case of Malaysia

Since the colonisation era, the immigrants from mainland China (and now their descendents) dominate the Malaysian housing industry. Their high entrepreneurial ethics stimulated early venture in all economic sectors to become dominant in business. To increase the participation of indigenous entrepreneurs in economic activities, Malaysia has practiced its own version of the affirmative policy since the 1970s which is known as National Economic Policy (NEP). Unlike other economic sectors such as construction, manufacturing and agricultural, the government has not provided special assistance (other than those that are generic in nature) for the indigenous populace to penetrate and thrive in housing development. As a consequence, their participation in this sector is conspicuous by their absence. A study was conducted to look into the involvement of indigenous housing developers in housing industry. Data was collected through postal questionnaires followed by face-to-face interviews. The discussion on the data analysis is presented together with interview findings.indigenous housing developer, housing development industry, entrepreneur characteristic

Modeling the correlations of crude oil properties based on sensitivity based linear learning method

This paper presented a new prediction model of pressure–volume–temperature (PVT) properties of crudeoil systems using sensitivity based linear learning method (SBLLM). PVT properties are very important in the reservoir engineering computations. The accurate determination of these properties, such as bubble-point pressure and oil formation volume factor, is important in the primary and subsequent development of an oil field. Earlier developed models are confronted with several limitations especially their instability and inconsistency during predictions. In this paper, a sensitivitybasedlinearlearningmethod (SBLLM) prediction model for PVT properties is presented using three distinct databases while comparing forecasting performance, using several kinds of evaluation criteria and quality measures, with neural network and the three common empirical correlations. In the formulation used, sensitivity analysis coupled with a linear training algorithm for each of the two layers is employed which ensures that the learning curve stabilizes soon and behaves homogenously throughout the entire process operation. In this way, the model will be able to adequately model PVT properties faster with high stability and consistency. Empirical results from simulations demonstrated that the proposed SBLLM model produced good generalization performance, with high stability and consistency, which are requisites of good prediction models in reservoir characterization and modeling

Estimation of the engineering elastic constants of a directionally solidified superalloy for finite element structural analysis

The temperature-dependent engineering elastic constants of a directionally solidified nickel-base superalloy were estimated from the single-crystal elastic constants of nickel and MAR-MOO2 superalloy by using Wells' method. In this method, the directionally solidified (columnar-grained) nickel-base superalloy was modeled as a transversely isotropic material, and the five independent elastic constants of the transversely isotropic material were determined from the three independent elastic constants of a cubic single crystal. Solidification for both the single crystals and the directionally solidified superalloy was assumed to be along the (001) direction. Temperature-dependent Young's moduli in longitudinal and transverse directions, shear moduli, and Poisson's ratios were tabulated for the directionally solidified nickel-base superalloy. These engineering elastic constants could be used as input for performing finite element structural analysis of directionally solidified turbine engine components

Thermal-structural analyses of Space Shuttle Main Engine (SSME) hot section components

Three dimensional nonlinear finite element heat transfer and structural analyses were performed for the first stage high pressure fuel turbopump (HPFTP) blade of the space shuttle main engine (SSME). Directionally solidified (DS) MAR-M 246 and single crystal (SC) PWA-1480 material properties were used for the analyses. Analytical conditions were based on a typical test stand engine cycle. Blade temperature and stress strain histories were calculated by using the MARC finite element computer code. The structural response of an SSME turbine blade was assessed and a greater understanding of blade damage mechanisms, convective cooling effects, and thermal mechanical effects was gained

The security gap in Syria: individual and collective security in ‘rebel-held’ territories

This paper examines security in Syria through the conceptual lens of the security gap, understood as the gap between security practices and objectives which have implications for individual and collective security. Practices of security can be the state apparatus, the military, and militias. The objective – safety – can refer to the safety or security of a range of collectives including the state, political parties, and ethnic groups, while individual security refers to the general safety of inhabitants and the protection of human rights. This paper compares the security situation in so-called ‘rebel-held’ areas of Syria where alternative governance structures have emerged, examining the security approaches of Local Administrative Councils and Rebel Councils in Deir Azzor, Manbij, Dera, and areas dominated by the Kurdish Democratic Union Party (PYD). It argues that security and safety are strongly influenced by authority formation and the nature of deals and relationships involved in the formation of these nascent authorities. It also argues that security in these areas is strongly influenced by the Syrian government, which disrupts collectives that threaten its own collective security while giving limited support to those which serve its agenda of retaining power. It also demonstrates the limited utility of the ‘regime’ vs. ‘rebel-held’ dichotomy, as rebel groups at times must accommodate the Syrian state in limited ways for instrumental purposes. The article is based on fieldwork conducted in Turkey in 2013–2014, interviews conducted in 2015, and secondary sources based on field research

Multi-Index Monte Carlo: When Sparsity Meets Sampling

We propose and analyze a novel Multi-Index Monte Carlo (MIMC) method for weak approximation of stochastic models that are described in terms of differential equations either driven by random measures or with random coefficients. The MIMC method is both a stochastic version of the combination technique introduced by Zenger, Griebel and collaborators and an extension of the Multilevel Monte Carlo (MLMC) method first described by Heinrich and Giles. Inspired by Giles's seminal work, we use in MIMC high-order mixed differences instead of using first-order differences as in MLMC to reduce the variance of the hierarchical differences dramatically. This in turn yields new and improved complexity results, which are natural generalizations of Giles's MLMC analysis and which increase the domain of the problem parameters for which we achieve the optimal convergence, $\mathcal{O}(\text{TOL}^{-2}).$ Moreover, in MIMC, the rate of increase of required memory with respect to $\text{TOL}$ is independent of the number of directions up to a logarithmic term which allows far more accurate solutions to be calculated for higher dimensions than what is possible when using MLMC. We motivate the setting of MIMC by first focusing on a simple full tensor index set. We then propose a systematic construction of optimal sets of indices for MIMC based on properly defined profits that in turn depend on the average cost per sample and the corresponding weak error and variance. Under standard assumptions on the convergence rates of the weak error, variance and work per sample, the optimal index set turns out to be the total degree (TD) type. In some cases, using optimal index sets, MIMC achieves a better rate for the computational complexity than the corresponding rate when using full tensor index sets..
