Paradigms and promises : new approaches to educational administration

In the field of educational administration there have been several years of active debate over how America's school systems are run. Contemporary educational administrators have been forced to reflect not only on educational policy and practice, but on the very nature of their position. How does administration contribute to the type of society we have? In what ways does it impede or enhance our cultural ideals and values? "Paradigms and Promises" offers an unorthodox solution by presenting administration as an arena for critical reflection and humanistic action, rather than a more technically-oriented style of management. Foster's critical analysis is premised on an understanding of the relationship of theory to practice, and as he provides alternative theories, he sheds new light on educational administration. Orthodox administrative theory receives heavy criticism in this text. Foster employs progressive critical theory as well as conventional analyses in critical appraisal, and advocates a dialectical concept, through which administrators, teachers and students are encouraged to challenge and question each other - the eventual result being a more responsive, democratically-run system.
The Changing Architecture of Global Science

The emerging political economy of global science is a significant factor influencing economic, social and cultural development, building national systems of innovation, and the rise of new multinational corporate, private/public and community involvement.1 It is only since the 1960s with the development of research evaluation and increasing sophistication of bibliometrics that it has been possible to map this emerging economy of global science on a comparative national and continental basis.2

Sensor network based device free trespasser detection and localisation

Device free detection and localization is a promising and a very practical research area where installation of expensive sensors and/or tagging the intruder is not feasible. This paper reports a mesh network developed for device free trespasser detection. We use the Received Signal Strength Indicator (RSSI) measurements of the wireless links within the mesh as the sole sensing mechanism. A fingerprint of RSSI measurements characterizes the environment under normal conditions including multi-path effects. A technique to differentiate RSSI variations due to trespassers from those due to multi-path effects is demonstrated. The results of the experiments conducted in an outdoor environment have verified that the proposed method can be used to detect trespassers successfully. The reliability of the detection is improved by cross-correlating RSSI variations among the multiple links in the mesh. The ability to extend the system for localization is also investigated.
Random safety audits in the neonatal unit

Background: Random safety audits have been shown to be effective in improving standards of practice in high-risk industries. They are process audits rapidly performed during real-time clinical activity, with immediate feedback, allowing for immediate change of practice. Aim: Based on a concept described by the Vermont-Oxford Network, we aimed to introduce random safety audits to our unit to improve infection control and routine neonatal care. Method: We designed simple data collection tables to audit 11 infection control and four routine care standards. Audits were undertaken during the weekly grand round. Immediate feedback was given. Results: In 6 months we completed three cycles of 15 audits each. Complete results were available for 14 audits. The compliance with the infection control standards improved from a median of 70% (range 20%–100%) to 95% (range 66%–100%). The results of the routine care standards were more variable. Conclusion: We have shown that this innovative method of random safety audits is effective in quickly improving practice. We believe this to be due to the instant feedback, continued emphasis on infection control and good clinical practice, and improved teamwork.
STRONGER ASSOCIATION RULES FOR POSITIVE ATTRIBUTES

By a context we mean a binary table with crosses at some entries, i.e. a relation between two sets. The elements of these sets are called objects (= row labels) and attributes (= column labels). Each context determines a pair of Galois closure operators. This gives rise to formal concept analysis, cf. Ganter and Wille [6], and also to studying strong association rules in data mining, cf. Agrawal, Imielinski and Swami [1]; the term “association rule” being kept for the fuzzy version. There are cases where the Galois closure is too large or, in other words, even the strong association rules challenge decision making with too many choices. In [3], some stronger association rules (i.e., a smaller pair of closure operators) have been introduced. Their mathematical features and possible further applicability have been studied in [4] and [5]. While [3] makes it clear that the new operator is useful in (pure) algebra, [4] and [5] point out that we expect its use in applied fields only when all the attributes are advantageous or good or useful, shortly, if the attributes are positive. The goal of this paper is to introduce a more general pair of closure operators, smaller than the Galois one, such that the corresponding stronger association rules take into account that not all the attributes are positive. The main result confirms that our definition gives indeed closure operators. A strong emphasis is put on detailing how and why the new stronger association rules promise future applications although no concrete database has been analyzed from this aspect yet.

A Video Transmission Framework Based on Packet Criticality Model

During video streaming over packet-erasure network, packets may lose due to network congestion. Since video packets have different significance and validity for decoding, the streaming system is expected to transmit the most critical packets when congestion occurs. In this paper, a packet criticality model is proposed and then a video transmission framework based on this model is presented. The criticality model describes how critical a video packet should be sent and provides information to transmitter to decide which packet to be transmitted firstly. Experimental results show that the proposed criticality model can help video streaming system with improved performance and raised quality of reconstructed images.
Prevention of DDoS Attacks 1

Distributed denial-of-service (DDoS) is an increasingly worrying threat to availability of Internet resources. DDoS Attacks have recently emerged as one of the most newsworthy, if not the greatest weaknesses of the Internet. DDoS attacks cause economic losses due to the unavailability of services and potentially serious security problems due to incapacitation of critical infrastructures. The goal of the paper is to place some order into the existing attack, defense principles and classification of DDoS prevention mechanisms so that a better understanding of DDoS attacks can be achieved. I. Introduction Distributed denial-of-service(DDoS), is a relatively simple, yet very powerful technique to attack Internet resources. With little or no advance warning, a DDoS attack can abruptly drain the computing and communication resources of its victim within a short time ,until the attack is resolved or in some cases slowly eat up the resources with out being noticed. Thus these disruptive or degrading attack flows often lead to complete shutdowns of Internet resources or at least cause performance degradations. Distributed Denial of Service (DDoS), is a simple, yet very powerful technique to attack Internet resources. DDoS attacks add the many-to-one dimension to the DoS problem making the prevention and mitigation of such attacks more difficult and the impact proportionally severe.
Frontostriatal Circuits and the Development of Bulimia Nervosa

Bulimia nervosa (BN) is characterized by both recurrent episodes of binge eating that are, in part, defined by a sense of loss of control and compensatory behaviors to avoid weight gain. Impulsive behaviors are also common in individuals with BN, indicating more pervasive difficulties in behavioral self-regulation. Findings from functional and anatomical neuroimaging studies of individuals with BN suggest dysfunction in the dorsal frontostriatal circuits that support self-regulatory capacities and habit learning and in overlapping ventral circuits that support reward processing and reward-based learning. In this review, we describe the normal development of frontostriatal circuits and then present behavioral and neuroimaging data from adolescents and adults with BN. These data suggest that the abnormal maturation of frontostriatal circuits may contribute to the habitual binge-eating and purging behaviors of BN. Future longitudinal imaging studies will improve understanding of how these circuits contribute to the developmental trajectory of BN and will inform novel interventions that could target or prevent the impulsive and habit-like features of this disorder.
Human Probing Behavior of Aedes aegypti when Infected with a Life-Shortening Strain of Wolbachia

Background Mosquitoes are vectors of many serious pathogens in tropical and sub-tropical countries. Current control strategies almost entirely rely upon insecticides, which increasingly face the problems of high cost, increasing mosquito resistance and negative effects on non-target organisms. Alternative strategies include the proposed use of inherited life-shortening agents, such as the Wolbachia bacterium. By shortening mosquito vector lifespan, Wolbachia could potentially reduce the vectorial capacity of mosquito populations. We have recently been able to stably transinfect Aedes aegypti mosquitoes with the life-shortening Wolbachia strain wMelPop, and are assessing various aspects of its interaction with the mosquito host to determine its likely impact on pathogen transmission as well as its potential ability to invade A. aegypti populations. Methodology/Principal Findings Here we have examined the probing behavior of Wolbachia-infected mosquitoes in an attempt to understand both the broader impact of Wolbachia infection on mosquito biology and, in particular, vectorial capacity. The probing behavior of wMelPop-infected mosquitoes at four adult ages was examined and compared to uninfected controls during video-recorded feeding trials on a human hand. Wolbachia-positive insects, from 15 days of age, showed a drastic increase in the time spent pre-probing and probing relative to uninfected controls. Two other important features for blood feeding, saliva volume and apyrase content of saliva, were also studied. Conclusions/Significance As A. aegypti infected with wMelPop age, they show increasing difficulty in completing the process of blood feeding effectively and efficiently. Wolbachia-infected mosquitoes on average produced smaller volumes of saliva that still contained the same amount of apyrase activity as uninfected mosquitoes. These effects on blood feeding behavior may reduce vectorial capacity and point to underlying physiological changes in Wolbachia-infected mosquitoes.
Utilizing Topographic Finance to Understand Volatility

Visual representation methods are a common problem in econometrics and finance in order to describe system dynamics. In this paper we address this problem by using the bi-harmonic oscillation process and the Brownian motion components, to generate a three-dimensional volatility surface.The empirical analysis have been carried out on the S&P500 Index, the 10-year US Treasury Rates, and the West Texas Intermediate oil price, by using 85 daily closing observations, at the purpose to show how visualization of volatility can help understand longitudinal movements of price within different asset classes.
Environmental Research and Public Health Pm 2.5 -induced Oxidative Stress and Mitochondrial Damage in the Nasal Mucosa of Rats

Exposure to PM 2.5 (particulate matter ≤2.5 µm) increases the risk of nasal lesions, but the underlying mechanisms, especially the mechanisms leading to mitochondrial damage, are still unclear. Thus, we investigated the in vivo effects of PM 2.5 exposure on the inflammatory response, oxidative stress, the enzyme activities of Na + K +-ATPase and Ca 2+-ATPase, and the morphology and function of mitochondria in the nasal mucosa of rats. Exposure to PM 2.5 occurred through inhalation of a PM 2.5 solution aerosol. The results show that the PM 2.5 exposure induced increased levels of malondialdehyde (MDA) and levels of proinflammatory mediators, including interleukin 6 (IL-6), IL-8, and tumor necrosis factor-α (TNF-α). These changes were accompanied by decreases in the activities of total superoxide dismutase (T-SOD), Na + K +-ATPase, and Ca 2+-ATPase in rat nasal mucosa. PM 2.5 significantly affected the expression of specific mitochondrial fission/fusion genes (OPA1, Mfn1, Fis1, and Drp1) in nasal mucosa. These changes were accompanied by abnormal alterations of mitochondrial structures, including mitochondrial swelling, cristae disorder, and even fission resulting from higher doses of PM 2.5. Our data shows that oxidative damage, inflammatory response, and mitochondrial dysfunction may be the toxic mechanisms that cause nasal lesions after exposure to PM 2.5 .
Object-oriented model of parallel programs

The aim of this paper is to investigate an object oriented model of parallel programs in a distributed memory environment that is structural and yet has reduced complexity in dealing with parallel software. The presented model enables integration of well-known methods based on the common concept of a program control flow. A parallel program is described by a multi-flow graph, being an extension of an ordinary flow-graph. It allows developers to design structural tests, to assess test coverage and to estimate quality parameters.
Image Reconstruction Algorithm Based on Inverse Problem for Multi-Excitation-Modes Electromagnetic Tomography System

Electromagnetic Tomography (EMT) sensing system with multi-excitation-modes is introduced. It can produce three excitation modes, among which the quasi-parallel excitation mode can give more independent projections than the parallel mode and produces relatively more even sensitivity distribution than the coil-pair mode. A new kind of image reconstruction algorithm based on inverse problem is proposed for the quasi-parallel excitation mode. The simulated results prove that this algorithm performs better than the former algorithms.
Performance Analysis of SRTLD and BIOSARP Protocols in Wireless Sensor Networks

With the growing of wireless network technology researchers find that Wireless Sensor Network (WSN) is one the newest technology to make the life more comfortable and interesting. Security is needed to ensure the communication between the sensor node which is already a part from the same network and not outside intruder or attacker. To guarantee implementing the security in wireless sensor network, there are many protocols coming into the picture; this project selects the recent two protocols SRTLD and BIOSARP for critical analysis and investigation. After comparing the power consumption and delivery ratio to guarantee long life time for sensor node and to ensure the wireless senor network is working probably. According to what we reviewed there is an essential need to critical analyzes the recent security protocols in WSNs to determine which protocol is suitable for each network and application type. Two different security protocols for wireless sensor networks (WSN) will be analyzed to study the most effective protocol. After implementing BIOSARP and SRTLD using NS-2 simulator the project found that SRTLD is better energy consumption by 16.82%, but in delivery ratio BIOSARP is better by 4.21%.
Cloud resource provisioning for Amazon EC2

The Cloud Computing can be used as a buzzword for the big turn to an IT world where computing resources provided over the internet can be acquired from IaaS providers with different purchasing plans. A critical challenge is to determine the right amount of resources to minimize the completion time and financial cost from consumers point of view. Finding optimal provisioning solutions thus becomes an NP problem. Taking Amazon EC2 for instance, it provides three purchasing plans with different price and yields different benefits to consumers. This paper addresses the issue of how cloud consumers could make resource provisioning plan for their computation. Heuristic algorithm is devised to determine number of instances required to execute workload so as to achieve optimization goal based on the characteristics of workload and purchasing plans provided by Amazon EC2 which can significantly reduce the total cost incurred to consumer.
The impact of long working hours on employed fathers and their families

In Australia and other western countries, two countervailing trends relating to workforce participation have affected family life. On the one hand, there has been a surge in the workforce participation of women – including women with partners and dependent children and associated calls on fathers to play a more active role in the non-financial aspects of home making. On the other hand, the proportion of men working long hours is considerably greater today than it was 20 years ago. This paper uses data from the first wave of the Household, Income and Labour Dynamics in Australia (HILDA) Survey to examine links between aspects of work hours (most particularly, the number of hours usually worked and the satisfaction with this regime), other employment circumstances, family characteristics, perceptions of work-family balance, and wellbeing across various other domains of personal and family life. The HILDA survey is the first household panel survey in Australia. It has been designed to improve our understanding of the dynamics of and interconnections between various aspects of life, including labour force participation, financial circumstances and housing, family formation, relationships and parenting, and personal attitudes, health and subjective wellbeing (for further information, see the HILDA website, http://www.melbourneinstitute.com/hilda/). The present paper represents a preliminary analysis that is designed to stimulate discussion, in preparation for a more detailed analysis of links between working hours and wellbeing.
Effect of eating vegetables before carbohydrates on glucose excursions in patients with type 2 diabetes

The aim of this review was to evaluate whether eating vegetables before carbohydrates could reduce the postprandial glucose, insulin, and improve long-term glycemic control in Japanese patients with type 2 diabetes. We studied the effect of eating vegetables before carbohydrates on postprandial plasma glucose, insulin, and glycemic control for 2.5 y in patients with type 2 diabetes. The postprandial glucose and insulin levels decreased significantly when the patients ate vegetables before carbohydrates compared to the reverse regimen, and the improvement of glycemic control was observed for 2.5 y. We also compared the postprandial glucose and glucose fluctuations assessed by continuous glucose monitoring system for 72-h in patients with type 2 diabetes and subjects with normal glucose tolerance when subjects ate vegetables before carbohydrates and carbohydrates before vegetables in a randomized crossover design. The glycemic excursions and incremental glucose peak were significantly lower when the subjects ate vegetables before carbohydrates compared to the reverse regimen. This evidence supports the effectiveness of eating vegetables before carbohydrates on glucose excursions in the short-term and glycemic control in the long-term in patients with type 2 diabetes.
DECIDE: An Interoperative Environment for Distributed Diagnostic Expert Systems

When one diagnostic expert system fails in solving problems alone, how can it get information available to improve itself from another similar diagnostic expert system ? This paper presents the interoperation environment to support the process. First, inference primitive structure templates have been presented to share inference structures between two diagnostic expert systems. Next, the cooperation method has been presented, using the di erence arising in the context of the correspondence between inference primitives of an originator and those of a recipient. The wrapper with conversion facilities has been also provided, using a common domain ontology developed manually. After designing and implementing such an interoperation environment, the experiment has been done between the following model-based like diagnostic expert systems in real task-domains, a trouble-shooting expert system and an enterprise diagnosis ( nancial management) expert system. The empirical results have shown us that the former supports the latter in nding a better solution.
The History of the Basic Symptom Concept

Th e basic symptom concept (BSC) has been developed since the 50s by clinical psychiatrists [66-70] and, independently of this group, in the 70s by clinical psychologists [144, 146]. A comprehensive synopsis of the concept of basic symptoms (BS) and basic stages has been given a.o. in the book of Süllwold and Hu-ber [147], in the seven editions of Huber's textbook of psychiatry since 1974 [99] and in my papers »Pure defect syndromes and basic stages of endogenous psy-choses« [72] and »Th e concept of substrate-close basic symptoms and its meaning for theory and therapy of schizophrenic disorders« [80], furtheron in the reports Th e BSC originated with two observations which I made in the early 50s as a pupil of Kurt Schneider in his University Hospital in Heidelberg. Th e one concerned the so-called pure defect syndromes [70, 72], the other the cenesthetic type of schizophrenia [69, 91] with its long lasting prodromes, preceding the fi rst psychotic episode. (1) Pure defect syndrome of schizophrenia. We observed patients whose psychopathological cross-sectional syndrome appeared at fi rst sight psycho-pathic-asthenic or organic-pseudoneurasthenic. Th e syndrome was determined by disturbances which were reported by the patients e.g. as diminished resistance to certain stressors, diminished resilience, energy, endurance, drive and activity, as increased exhaustibility and fatigability, as decreased emotional reagibility and as vegetative and sleep disorders. Only when the careful inquiry of case history had elicited psychotic episodes, as a rule occurring many years ago, the tentative diagnosis of a pure, nonpsychotic residual state of schizophrenia was possible. In the actual psychopathological picture none of the typical symptoms of schizophrenia could be recognized, as also K. Schneider at his own painstaking psycho-pathological exploration of those patients stated. It ensued that in these patients the psycho-pathologically uncharacteristic residues could not be diagnosed in their schizophrenic provenance without comprehensive inquiry and knowledge of the anamnesis [20, 21, 70, 72, 140]. In the following years, as I (G. Huber) was the chairman of the outpatient department of the Psychiatric University Hospital in Heidelberg, we followed-up patients in their domestic environment, who had shown as inpatients (1949-1953) a fl orid schizophrenic psychosis, but who were neither readmitted in the further course in a psychiatric hospital nor had a medical treatment as outpatients. Th e results of these follow-up studies were published in several papers since the late 50s [68, 69, 70, 71, 72]. We described the psychosyndromes …
