Investigation project: Representations about the professional role of recently graduated from the psychology career, state University of La Plata : Its relation with job insertion and performance

In this paper we present a research that took place between 2010 and 2012 included in an investigation scholarship awarded by the State University of la Plata. It is about the problem with the transition between college and professional work. It is a part of the produced studies on the importance of social representations as factors that impact on the performance of specific activities. In this case it's about finding out the relations given among the representations about graduated professional role of the Psychology career and its job insertion and performance. The theoretical framework corresponds to Social Psychology and Guidance theories. Methodologically this is an exploratory and descriptive study, based on the 'triangulation' conception, of multiple type, that allows combining in the same investigation, different strategies, theoretical perspectives and sources; however qualitative techniques were prioritized to analyze data. Finally there are some considerations about the social representations concerning to the professional performance, mainly in the clinical field associated to education, and also to the problems of both situations over other fields

Standard meteorological measurements on board of POLARSTERN during expedition ANT-IV (PS08, 4 cruises, south summer 1985/86) in the Atlantic and Weddell Sea, Antarctica

During the fourth Antarctic voyage ANT-IV of the research icebreaker POLARSTERN standard meteorological measurements have been performed. The measurements include 3-hourly synoptic observations as well as daily upper air soundings. The measurements started on September 6 1985 at Bremerhaven and were terminated at April 28 1986 in Punta Arenas. The 3-hourly synoptic observations are performed following the instructions of the FM 13 ships code defined by the World Meteorological Organization (WMO). The datasets include automatic measurements such as mean ship's speed, wind velocity, wind direction, air temperature, water temperature as well as visual observations such as total cloud amount, present weather, clouds, height and period of swell waves, ice classification. The visual observation are not performed during night time. For the upper air soundings VAISALA RS80 radiosondes, carried by helium-filled balloons (TOTEX 350 - 1500) were used. Data reception and evaluation were carried out by a MicroCora System (VAISALA). The upper air soundings include profile measurements of pressure, temperature, relative humidity and wind vector. Usually the soundings started at the heliport (10 m above sea level) and terminated between 15 and 37 km. The height of the measurements was calculated by applying the barometric formula. The wind vector was determined with the aid of the OMEGA navigation system.

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.

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.

Yeast chorismate mutase in the R state: Simulations of the active site

The isomerization of chorismate to prephenate by chorismate mutase in the biosynthetic pathway that forms Tyr and Phe involves C5—O (ether) bond cleavage and C1—C9 bond formation in a Claisen rearrangement. Development of negative charge on the ether oxygen, stabilized by Lys-168 and Glu-246, is inferred from the structure of a complex with a transition state analogue (TSA) and from the pH-rate profile of the enzyme and the E246Q mutant. These studies imply a protonated Glu-246 well above pH 7. Here, several 500-ps molecular dynamics simulations test the stability of enzyme–TSA complexes by using a solvated system with stochastic boundary conditions. The simulated systems are (i) protonated Glu-246 (stable), (ii) deprotonated Glu-246 (unstable), (iii) deprotonated Glu-246 plus one H2O between Glu-246 and the ether oxygen (unstable), (iv) the E246Q mutant (stable), and (v) addition of OH− between protonated Glu-246 and the ether oxygen. In (v), a local conformational change of Lys-168 displaced the OH− into the solvent region, suggesting a possible rate-determining step that precedes the catalytic step. In a 500-ps simulation of the enzyme complexed with the reactant chorismate or the product prephenate, no water molecule remained near the oxygen of the ligand. Calculations using the linearized Poisson–Boltzmann equation show that the effective pKa of Glu-246 is shifted from 5.8 to 8.1 as the negative charge on the ether oxygen of the TSA is changed from −0.56 electron to −0.9 electron. Altogether, these results support retention of a proton on Glu-246 to high pH and the absence of a water molecule in the catalytic steps.
