The Changing Nature of Employment and the Reform of Labor and Social Security Legislation in Post-Apartheid South Africa

This paper tries to understand the current status of South African labor market, which is changing in contradictory directions, i.e. a strengthening of the rights and protection of workers at the same time as the flexibilization of employment, in the context of the characteristics of labor and social security legislation in South Africa, as well as the nature of labor and social security reforms after democratization. We put emphasis on the corporatist nature of labor policy-making as the factor influencing the course of reforms; it is argued that the apparently contradictive changes can be explained consistently by the corporatist labor policy-making process which has been practiced notwithstanding the problem of representativeness.

Decentralization in Nation State Building of Indonesia

Introduction：Today, many countries, regardless of developed or developing, are trying to promote decentralization. According to Manor, as his quoting of Nickson’s argument, decentralization stems from the necessity to strengthen local governments as proxy of civil society to fill the yawning gap between the state and civil society (Manor [1999]: 30). With the end to the Cold War following the collapse of the Soviet Union rendering the cause of the “leadership of the central government to counter communism” meaningless, Manor points out, it has become increasingly difficult to respond flexibly to changes in society under the centralized system. Then, what benefits can be expected from the effectuation of decentralization? Litvack-Ahmad-Bird cited the four points: attainment of allocative efficiency in the face of different local preferences for local public goods; improvement to government competitiveness; realization of good governance; and enhancement of the legitimacy and sustainability of heterogeneous national states (Litvack, Ahmad & Bird [1998]: 5). They all contribute to reducing the economic and social costs of a central government unable to respond to changes in society and enhancing the efficiency of state administration through the delegation of authority to local governments. Why did Indonesia have a go at decentralization? As Maryanov recognizes, reasons for the implementation of decentralization in Indonesia have never been explicitly presented (Maryanov [1958]: 17). But there was strong momentum toward building a democratic state in Indonesia at the time of independence, and as indicated by provisions of Article 18 of the 1945 Constitution, there was the tendency in Indonesia from the beginning to debate decentralization in association with democratization. That said debate about democratization was fairly abstract and the main points are to ease the tensions, quiet the complaints, satisfy the political forces and thus stabilize the process of government (Maryanov [1958]: 26-27). 　　　What triggered decentralization in Indonesia in earnest, of course, was the collapse of the Soeharto regime in May 1998. The Soeharto regime, regarded as the epitome of the centralization of power, became incapable of effectively dealing with problems in administration of the state and development administration. Besides, the post-Soeharto era of “reform (reformasi)” demanded the complete wipeout of the Soeharto image. In contraposition to the centralization of power was decentralization. The Soeharto regime that ruled Indonesia for 32 years was established in 1966 under the banner of “anti-communism.” The end of the Cold War structure in the late 1980s undermined the legitimate reason the centralization of power to counter communism claimed by the Soeharto regime. The factor for decentralization cited by Manor is applicable here. 　　　Decentralization can be interpreted to mean not only the reversal of the centralized system of government due to its inability to respond to changes in society, as Manor points out, but also the participation of local governments in the process of the nation state building through the more positive transfer of power (democratic decentralization) and in the coordinated pursuit with the central government for a new shape of the state. However, it is also true that a variety of problems are gushing out in the process of implementing decentralization in Indonesia. 　　　This paper discusses the relationship between decentralization and the formation of the nation state with the awareness of the problems and issues described above. Section 1 retraces the history of decentralization by examining laws and regulations for local administration and how they were actually implemented or not. Section 2 focuses on the relationships among the central government, local governments, foreign companies and other actors in the play over the distribution of profits from exploitation of natural resources, and examines the process of the ulterior motives of these actors and the amplification of mistrust spawning intense conflicts that, in extreme cases, grew into separation and independence movements. Section 3 considers the merits and demerits at this stage of decentralization implemented since 2001 and shed light on the significance of decentralization in terms of the nation state building. Finally, Section 4 attempts to review decentralization as the “opportunity to learn by doing” for the central and local governments in the process of the nation state building. 　　　In the context of decentralization in Indonesia, deconcentration (dekonsentrasi), decentralization (desentralisasi) and support assignments (tugas pembantuan; medebewind, a Dutch word, was used previously) are defined as follows. Dekonsentrasi means that when the central government puts a local office of its own, or an outpost agency, in charge of implementing its service without delegating the administrative authority over this particular service. The outpost agency carries out the services as instructed by the central government. A head of a local government, when acting for the central government, gets involved in the process of dekonsentrasi. Desentralisasi, meanwhile, occurs when the central government cedes the administrative authority over a particular service to local governments. Under desentralisasi, local governments can undertake the particular service at their own discretion, and the central government, after the delegation of authority, cannot interfere with how local governments handle that service. Tugas pembantuan occur when the central government makes local governments or villages, or local governments make villages, undertake a particular service. In this case, the central government, or local governments, provides funding, equipment and materials necessary, and officials of local governments and villages undertake the service under the supervision and guidance of the central or local governments. Tugas pembantuan are maintained until local governments and villages become capable of undertaking that particular service on their own.

Backward-bending of labor supply function and free riders

It seems like that backward- bending of labor supply function can be observed in Central Asian Countries such as Uzbekistan and Kazakhstan. People’s basic needs of life are satisfied and they do not increase labor supplies even if wage increases. It is possible to find some cases in which slowdowns increase, when a manager in a firm enforces penalties for workers have slowdowns. This phenomenon occurs because a worker prefers the position of equilibrium on the labor supply function always in the upper direction. This article explains the increase of free-riders by penalties and how to avoid them.

Authoritarianism and labor market : preference of labor policies in the Arab Gulf countries

Migrant and labor issues are a primary concern in the Arab Gulf countries. With focus on the economic and political conditions that influence actors' decisions when framing labor policies, this study analyzes how preferences of such policies are formed and explains why the governments of the Arab Gulf countries attempt to implement less economical policies. The findings suggest that governments avoid concessions for enterprises required to implement more economical policies and chose uneconomical ones to maintain authoritarian regimes.

Reaction pathways in the solid state synthesis of multiferroic BiFeO 3

The obtaining of multiferroicBiFeO3 as a pure single-phase product is particularly complex since the formation of secondary phases seems to be unavoidable. The process by which these secondary impurities are formed is studied by analyzing the diffusion and solidstate reactivity of the Bi2O3–Fe2O3 system. Experimental evidence is reported which indicates that the progressive diffusion of Bi3+ ions into the Fe2O3 particles governs the solidstatesynthesis of the perovskite BiFeO3 phase. However a competition is established between the diffusion process which tends to complete the formation of BiFeO3, and the crystallization of stable Bi2Fe4O9 mullite crystals, which tend to block that formation reaction.

Steady state analysis of a storage integrated solar thermophotovoltaic (SISTPV) system

This paper presents the theoretical analysis of a storage integrated solar thermophotovoltaic (SISTPV) system operating in steady state. These systems combine thermophotovoltaic (TPV) technology and high temperature thermal storage phase-change materials (PCM) in the same unit, providing a great potential in terms of efficiency, cost reduction and storage energy density. The main attraction in the proposed system is its simplicity and modularity compared to conventional Concentrated Solar Power (CSP) technologies. This is mainly due to the absence of moving parts. In this paper we analyze the use of Silicon as the phase change material (PCM). Silicon is an excellent candidate because of its high melting point (1680 K) and its very high latent heat of fusion of 1800 kJ/kg, which is about ten times greater than the conventional PCMs like molten salts. For a simple system configuration, we have demonstrated that overall conversion efficiencies up to ?35% are approachable. Although higher efficiencies are expected by incorporating more advanced devices like multijunction TPV cells, narrow band selective emitters or adopting near-field TPV configurations as well as by enhancing the convective/conductive heat transfer within the PCM. In this paper, we also discuss about the optimum system configurations and provide the general guidelines for designing these systems. Preliminary estimates of night time operations indicate it is possible to achieve over 10 h of operation with a relatively small quantity of Silicon.

Variable threshold algorithm for division of labor analyzed as a dynamical system

Division of labor is a widely studied aspect of colony behavior of social insects. Division of labor models indicate how individuals distribute themselves in order to perform different tasks simultaneously. However, models that study division of labor from a dynamical system point of view cannot be found in the literature. In this paper, we define a division of labor model as a discrete-time dynamical system, in order to study the equilibrium points and their properties related to convergence and stability. By making use of this analytical model, an adaptive algorithm based on division of labor can be designed to satisfy dynamic criteria. In this way, we have designed and tested an algorithm that varies the response thresholds in order to modify the dynamic behavior of the system. This behavior modification allows the system to adapt to specific environmental and collective situations, making the algorithm a good candidate for distributed control applications. The variable threshold algorithm is based on specialization mechanisms. It is able to achieve an asymptotically stable behavior of the system in different environments and independently of the number of individuals. The algorithm has been successfully tested under several initial conditions and number of individuals.
