服务型政府一公共行政的理性选择

在马克思·韦伯提出关于“合理性”的概念以后，对于其价值理性与工具理性的讨论便在在学术界生生不息。价值理性与工具理性对于服务型政府建设的理论认识题中必有意义“本文以马克斯韦伯的合理性为出发点，在公共行政的框架下讨论工具理性与价值理性的辩证关系，从而在理性选择层面，为服务型政府的提出找到了哲学基础，并呼吁价值理性的回归。

Metabolic Changes in Rats with Photochemically Induced Cerebral Infarction and the Effects of Batroxobin:A Study by Magnetic Resonance Imaging,~1H-and ^(31)p-Magnetic Resonance Spectroscopy

Metabolic changes in rats with photochemically induced cerebral infarction and the effects of batroxobin were investigated 1, 3, 5 and 7 days after infarction by means of magnetic resonance imaging (MRI), 1H- and 31P-magnetic resonance spectroscopy (MRS). A region of T2 hyperintensity was observed in left temporal neocortex in infarction group and batroxobin group 1, 3, 5 and 7 days after infarction. The volume of the region gradually decreased from 1 day to 7 days after infarction. The ratio of NAA/Cho + Cr in the region of T2 hyperintensity in the infarction group was significantly lower than that in the corresponding region in the sham-operated group 3, 5 and 7 days after infarction respectively (P

Magnetic resonance imaging:A new tool for diagnosis of acute ischemic colitis?

AIM： To define the evolution of ischemic lesions with 7T magnetic resonance imaging （7T-MRI） in an animal model of acute colonic ischemia. METHODS： Adult Sprague-Dawley rats were divided into two groups. Group I underwent inferior mesenteric artery （IMA） ligation followed by macroscopic observa- tions and histological analysis. In group H, 7T-MRI was performed before and after IMA ligation and followed by histological analysis. RESULTS： Morphological alterations started to develop 1 h after IMA ligation, when pale areas became evident in the splenic flexure mesentery and progressively wors-ened up to 8 h thereafter, when the mesentery was less pale, and the splenic flexure loop appeared very dark. The 7T-MRI results reflected these alterations, showing a hyperintense signal in both the intraperitoneal space and the colonic loop wall 1 h after IMA ligation; the lat- ter progressively increased to demonstrate a reduction in the colonic loop lumen at 6 h. Eight hours after IMA ligation, MRI showed a persistent colonic mural hyper- intensity associated with a reduction in peritoneal free fluid. The 7T-MRI findings were correlated with histolog- ical alterations, varying from an attenuated epithelium with glandular apex lesions at 1 h to coagulative necro- sis and loss of the surface epithelium detected 8 h after IMA ligation. CONCLUSION： MRI may be used as a substitute for invasive procedures in diagnosing and grading acute ischemic colitis, allowing for the early identification of pathological findings.

The Current Metamorphosis of Instrumental Rationality

In the first part, the concept of instrumental reason is defended. Although we live in the age of pluralism, in which a tendency prevails to put all types of rationality on the same plane, there is a rationality that has a unique position： the instrumental rationality. The article then examines Luk^ics＇s roots of this concept and its elaboration by Adomo and Horkheimer. The second part refers to the current transformation of instrumental reason that these authors could not register. Instrumental reason changes so that it can connect several seemingly incoherent elements： postmodern non-objectivity, social and ecological normativity, and reified imperatives of capitalism. This formation is here called over-instrumental instrumental reason. In conclusion, the article deals with the question of how its non-instrumental component to exempt from its instrumental ones.

Development of Diamond-like Carbon Fibre Wheel

A unique diamond-like carbon (DLC) grinding wheel was developed, in which the DLC fibres were made by rolling Al sheets coated with DLC films and aligned no rmally to the grinding wheel surface by laminating Al sheets together with DLC fibres. In this paper, the formation process of DLC fibres and the fabrication process of a DLC fibre wheel were investigated. Many grinding experiments were also carried out on a precision NC plane milling machine using a newly developed DLC wheel. Grinding of specimens of silicon wafers, optical glasses, quartz, granites and hardened die steel SKD11 demonstrated the capabilities of nanometer surface finish. A smooth surface with a roughness value of Ra2.5 nm (Ry26 nm) was achieved.

Storage and Management for Medicines in the Home of University Students of the Health Area of Espoch, Ecuador

This work collects the characteristics of the family kits of students from the careers related to health in the Espoch, by identifying their knowledge and habits to determine the relationship between self-medication and the possession of medicines contained in the first-aid kit. This is related to the most outstanding frequency （48.1% bedroom） with the use of medicines in the home （48.5% when the treatment ends）. Taking into account that 63.6% do not have a kit, they stored them in inadequate places to control their stability and quality for the use they were made, being analgesics and antibiotics those commonly found during the inspection that took place in the home. This determines that storage habits are not adequate for the proper storage of medications, including having knowledge of health and the importance of proper use by students, being essential to know that medicines must be stored in fresh places and dry, to avoid damage and problems associated with its stability.

Adaptive fuzzy integral sliding mode pressure control for cutter feeding system of trench cutter

A nonlinear pressure controller was presented to track desired feeding pressure for the cutter feeding system(CFS) of trench cutter(TC) in the presence of unknown external disturbances.The feeding pressure control of CFS is subjected to unknown load characteristics of rock or soil; in addition,the geological condition is time-varying.Due to the complex load characteristics of rock or soil,the feeding velocity of TC is related to geological conditions.What is worse,its dynamic model is subjected to uncertainties and its function is unknown.To deal with the particular characteristics of CFS,a novel adaptive fuzzy integral sliding mode control(AFISMC) was designed for feeding pressure control of CFS,which combines the robust characteristics of an integral sliding mode controller and the adaptive adjusting characteristics of an adaptive fuzzy controller.The AFISMC feeding pressure controller is synthesized using the backstepping technique.The stability of the overall closed-loop system consisting of the adaptive fuzzy inference system,integral sliding mode controller and the cutter feeding system is proved using Lyapunov theory.Experiments are conducted on a TC test bench with the AFISMC under different operating conditions.The experimental results demonstrate that the proposed AFISMC feeding pressure controller for CFS gives a superior and robust pressure tracking performance with maximum pressure tracking error within ?0.3 MPa.

Measuring and mapping the pollution data and at the same time performing the geographical analysis of the complexity and the characteristics of natural and human environment can be useful tool in observation, management, and planning of the environmental policy of the country.

PSSA-Management Tool for Protection of a Marine Biodiversity in the Vietnam East Sea

Particularly Sensitive Sea Areas （PSSA） is an important management tool for protection of marine biodiversity of a marine area. At the time of designation of PSSA, an associated protective measure, which meets the requirements of the appropriate legal instrument establishing such measure, must have been approved or adopted by IMO to prevent, reduce, or eliminate the threat or identified vulnerability. Information on each of the PSSA that has been designated by IMO is available on the nautical chart. The Vietnam＇s coastal zones and island is an isolated oceanic habitat of extremely rich marine life in very good condition which is important to the maintenance and dispersal of the marine life of the Western Tropical Pacific. Vietnam coastal areas are very high risk areas affected by maritime activities, particularly international shipping, therefore in the future identification of some PSSA is necessary.

Landscape and Road Integration in Greece

This paper concerns the Strategic Environmental Assessment of the construction of some major Greek motorways： the Ionia Motorway, the Peloponnese Motorway and the Athens-Lamia Motorway. In the beginning the natural and cultural diversity of the Greek landscape as well as its conservation needs are discussed. The landscape impact assessment methodology consists of the identification of environmental goals, of sensitive landscape parameters, of environmental indicators and of acceptable impact thresholds. The selection of alternative solutions as well as of mitigation measures has been studied, on the basis of relevant environmental indicators. The developed methodology may constitute a tool for the environmental management of other road programs of great scale.

A novel smooth and discontinuous oscillator with strong irrational nonlinearities

In this paper,we propose a novel nonlinear oscillator with strong irrational nonlinearities having smooth and discontinuous characteristics depending on the values of a smoothness parameter.The oscillator is similar to the SD oscillator,originally introduced in Phys Rev E 69(2006).The equilibrium stability and the complex bifurcations of the unperturbed system are investigated.The bifurcation sets of the equilibria in parameter space are constructed to demonstrate transitions in the multiple well dynamics for both smooth and discontinuous regimes.The Melnikov method is employed to obtain the analytical criteria of chaotic thresholds for the singular closed orbits of homoclinic,homo-heteroclinic,cuspidal heteroclinic and tangent homoclinic orbits of the perturbed system.

Comprehension of functional support by enculturated chimpanzees Pan troglodytes

Studies of causal understanding of tool relationships in captive chimpanzees have yielded disparate findings, particularly those reported by Povinelli ＆ colleagues （2000） for tool tasks by laboratory chimpanzees. The present set of experiments tested nine enculturated chimpanzees on three versions of a support task, as described by Povinelli （2000）, during which food re- wards were presented in different experimental configurations. In Experiment 1, stimulus pairs included a choice between a cloth with a reward on the upper right comer or with a second reward off the cloth, adjacent to a comer, with the second pair comprised of a cloth with food on the upper right comer, and a second cloth with the reward on the substrate, partially covered. All subjects were successful with both test conditions in Experiment 1. In a second study, the experimental choices included one of two possi- ble correct options, paired with one of three incorrect options, with the three incorrect choices all involving varying degrees of perceptual containment. All nine chimpanzees scored significantly above chance across all six conditions. In Experiment 3, four unique conditions were presented, combining one of two possible correct choices with one of two incorrect choices. Six of the subjects scored significantly above chance across the four conditions, and group performance on individual conditions was also significant. Superior performance was demonstrated by female subjects in Experiment 3, similar to sex differences in tool use previously reported for wild chimpanzees and some tool tasks in captive chimpanzees. The present results for Experiments 2 ＆ 3 were significantly differed from those reported by Povinelli et al. （2000） for laboratory-born, peer-reared chimpanzees. One contribution towards the dramatic differences between the two study populations may be the significant rearing and housing differences of the chimpanzee groups. One explanation is that under conditions of enculturation, rich social interactions with humans and conspecifics, as well as active exploration of artifacts, materials, and other aspects of their physical environment had a significant impact on the animals＇ ability to recognize the support relationships among the stimulus choices. Overall, the present findings provide strong support for the hypothesis that our chimpanzee subjects based their responses on an understanding of functional support which represented one facet of their folk physics repertoire [Current Zoology 57 （4）： 429-440, 2011].
