School effectiveness: new managerialism, quality and the Japanisation of education

School effectiveness is a microtechnology of change. It is a relay device, which transfers macro policy into everyday processes and priorities in schools. It is part of the growing apparatus of performance evaluation. Change is brought about by a focus on the school as a site-based system to be managed. There has been corporate restructuring in response to the changing political economy of education. There are now new work regimes and radical changes in organizational cultures. Education, like other public services, is now characterized by a range of structural realignments, new relationships between purchasers and providers and new coalitions between management and politics. In this article, we will argue that the school effectiveness movement is an example of new managerialism in education. It is part of an ideological and technological process to industrialize educational productivity. That is to say, the emphasis on standards and standardization is evocative of production regimes drawn from industry. There is a belief that education, like other public services can be managed to ensure optimal outputs and zero defects in the educational product.

Measurement of the salinity and freezing tolerance of Crataegus genotypes using chlorophyll fluorescence

The effect of increasing salinity and freezing stress singly and in combination on a range of chlorophyll fluorescence parameters in foliar tissue of six Crataegus genotypes was examined. In general, increased stress reduced fluorescence values and absorption, trapping and electron transport energy fluxes per leaf reaction center and cross section, with decreased sigmoidicity of OJIP curves as a measure of the plastoquinone pool, reflecting decreased energy fluxes. Based on percentage reduction in a performance index from controls compared to stress-treated values, plants were ranked in order of tolerant > intermediate > sensitive. Use of this PIp ranking criteria enabled the distinguishing of marked differences in foliar salt/freezing hardiness between the Crataegus species used. Interpretation of the photochemical data showed that salinity and freezing affects both the acceptor and donor side of Photosystem II, while OJIP observations provided information regarding structural and functional changes in the leaf photosynthetic apparatus of the test species. It is concluded that chlorophyll fluorescence offers a rapid screening technique for assessing foliar salinity and freezing tolerance of woody perennials

Everyday revolution: the making of the Soviet Urban commune

This chapter charts the rise the urban commune as a cultural construct in early Soviet Russia and, in so doing, explores the implication of assessing the spaces in-between the apparatus of state -- very much a new venture in Soviet history.

A mídia impressa sergipana nas eleições para governador em 2006: cobertura do Cinform, correio de Sergipe e jornal da cidade

The elections for governor in 2006 with its victory Marcelo Déda Workers Party (PT), were a landmark in the state of Sergipe, for the first time, called progressive fronts (an alliance of parties formed mostly by origin of the left) broke the hegemony of two political groups, Franco and the Alves, whose direction was in force for over 30 years. This study proceeds on the assumption that the print media has certain standards of conduct in covering the election period. Therefore, this study seeks to quantify, classify and compare data from three newspapers more representative of the State of Sergipe (Cinform, Cidade Journal and Correio de Sergipe) to analyze the behavior of these journals, such as private apparatus of hegemony in election coverage 2006. It also uses the concept of hegemony Gramsci and theories of journalism framing (Entman and Porto) and agenda setting (McCombs and Shaw) to identify these patterns

Direct effects of colchicine on myocardial function - Studies in hypertrophied and failing spontaneously hypertensive rats

The aging spontaneously hypertensive rat (SHR) is a model in which the transition from chronic stable left ventricular hypertrophy to overt heart failure can be observed. Although the mechanisms for impaired function in hypertrophied and failing cardiac muscle from the SHR have been studied, none accounts fully for the myocardial contractile abnormalities. The cardiac cytoskeleton has been implicated as a possible cause for myocardial dysfunction. If an increase in microtubules contributes to dysfunction, then myocardial microtubule disruption by colchicine should promote an improvement in cardiac performance. We studied the active and passive properties of isolated left ventricular papillary muscles from 18- to 24-month-old SHR with evidence of heart failure (SHR-F, n=6), age-matched SHR without heart failure (SHR-NF, n=6), and age-matched normotensive Wistar-Kyoto rats (WKY, n=5). Mechanical parameters were analyzed before and up to 90 minutes after the addition of colchicine (10(-5), 10(-4), and 10(-3) mol/L). In the baseline state, active tension (AT) developed by papillary muscles from the WKY group was greater than for SHR-NF and SHR-F groups (WKY 5.69+/-1.47 g/mm(2) [mean+/-SD], SHR-NF 3.41+/-1.05, SHR-F 2.87+/-0.26; SHR-NF and SHR-F P<0.05 versus WKY rats). The passive stiffness was greater in SHR-F than in the WKY and SHR-NF groups (central segment exponential stiffness constant, K-cs: SHR-F 70+/-25, SHR-NF 44+/-17, WKY 41+/-13 [mean+/-SD]; SHR-F P<0.05 versus; SHR-NF and WKY rats). AT did not improve after 10, 20, and 30 minutes of exposure to colchicine (10(-5), 10(-4), and 10(-3) mol/L) in any group. In the SHR-F group, AT and passive stiffness did not change after 30 to 90 minutes of colchicine exposure (10(-4) mol/L). In summary, the data in this study fail to demonstrate improvement of intrinsic muscle function in SHR with heart failure after colchicine. Thus, in the SHR there is no evidence that colchicine-induced cardiac microtubular depolymerization affects the active or passive properties of hypertrophied or failing left ventricular myocardium.

Comparative study on extracts from the tissue covering the stingers of freshwater (Potamotrygon falkneri) and marine (Dasyatis guttata) stingrays

Stingrays are elasmobranchs found along the seacoast and in some rivers of Brazil. Pain is the most conspicuous symptom observed in patients wounded by the bilaterally retroserrate stingers located in the tail, which are covered by glandular and integument tissues. In addition, cutaneous necrosis is commonly observed in injuries caused by freshwater stingrays. The aim of this work was to characterize and compare certain properties of tissue extracts obtained from the glandular tissues covering the stinger apparatus of Potamotrygon falkneri and Dasyatis guttata stingrays. By sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), tissue extracts have similar bands above 80kDa, but most differences were observed below this molecular mass. Lethal, dermonecrotic and myotoxic activities were detected only in P. falkneri tissue extract. Edematogenic activity was similar and dose dependent in both tissue extracts. Nociceptive activity was verified in both tissue extracts, but P. falkneri presented a two-fold higher activity than D. guttata tissue extract. No direct hemolysis, phospholipase A(2) and coagulant activities were observed in both tissue extracts. Antigenic cross-reactivity was noticed by ELISA and Western blotting, using antisera raised in rabbits. Species-specific sera reacted with several components of both tissue extracts, noticeably above 22 kDa. Both tissue extracts presented gelatinolytic, caseinolytic and fibrinogenolytic activities, which were not caused by the action of metalloproteinases. Hyaluronidase activity was detected only in P. falkneri tissue extract. Our experimental observations suggest that P. falkneri tissue extract is more toxic than D. guttata tissue extract. These results may explain why injuries caused by freshwater stingrays are more severe in human accidents. (c) 2007 Elsevier Ltd. All rights reserved.

Changes in the morphology and ultrastructure of the Dufour's gland during the life cycle of the bumble bee queen, Bombus terrestris L-(Hymenoptera : Bombini)

The Dufour's gland is found closely associated with the sting apparatus of all female hymenopterans, playing multiple roles among bees. In some species of Bombus the gland may be involved in production of nestmate recognition pheromones, but in B. terrestris its function is not certain yet. The morphology of the :Dufour's gland of B. terrestris queens and the ultrastructural features of its cells were studied in different ages and behavioural stages using routine transmission electron microscopy. Measurements of the length and the diameter of the gland in the same conditions were also made. The Dufour's gland of the queen increases significantly in size (both in length and in diameter) with age and reproductive activity the ultrastructural features of the gland show electrondense material that comes from the haemolymph. This material is also present in the intercellular spaces, and is conducted to the subcuticular space, to be released directly into the glandular lumen. Hence at least part of the secretion is probably taken up directly from the haemolymph. The ultrastructural features indicate a more active phase of the gland corresponding to the period of egg-laying of the queen, and a decrease in activity when the queen is in hibernation as well as after the competition point. In conclusion, the gland is probably involved in reproduction, more specifically, in the marking off eggs.

Jaw musculature of the Meiglyptini (Aves: Piciformes: Picidae)

The Meiglyptini comprise eight species of woodpeckers grouped into three genera, two of which contain three species ( Meiglyptes and Mulleripicus), while one genus includes two species ( Hemicircus). The purpose of this study is to describe the mandibular apparatus found in six species of Meiglyptini and to compare them with each other and with other woodpecker species. The results reveal a number of structures that are worth mentioning: (i) the components of the external mandibular adductor system of Hemicircus concretus, particularly the M. adductor mandibulae externus caudalis medialis, are underdeveloped compared with the other investigated species; (ii) the muscles of the internal mandibular system are structurally different among Meiglyptes species and are less developed, both in size and in structure, in H. concretus; (iii) the M protractor quadrati is vestigial in Meiglyptes species; (iv) the muscles of the protractor system of the quadrate are relatively undeveloped in H. concretus; (v) most of the muscles of the pterygoideus system are structurally differentiated in Meiglyptes species. It appears that the complexity of the mandibular apparatus is associated with the type of food consumed, as the apparatus of the frugivorous species H. concretus is markedly different from that of the insectivorous species. © 2012 The Royal Swedish Academy of Sciences.

Permethrin chronic exposure alters motor coordination in rats: Effect of calcium supplementation and amlodipine

Recently was observed that pyrethroids decrease motor coordination and that calcium channels can be important targets for this effect. To contribute with this observation, this work studied the motor coordination and exploration (using hole-board apparatus), and locomotion (using open-field apparatus) of rats exposed to following treatments: permethrin (PM), PM plus calcium gluconate (CG) and PM plus amlodipine (AML). The results obtained show that CG or AML alone not changed the motor coordination while PM decreases it. CG kept the effect of permethrin; AML, however, decreased the values of permethrin to the control. Locomotor activity and exploration, which could confound results of motor coordination, were not modified by treatments. The concentration of PM in brain tissue was increased by the CG and AML. The neurosomatic index (weight brain/body weight) was increased by the PM and PM + CG. In conclusion, the combined results here obtained indicates that the calcium ion and the channels in which it is involved can be important targets for the toxic effect of pyrethroid insecticide permethrin on motor nerve activity of rats.

Working Alliance Inventory-Short Revised (WAI-SR): psychometric properties in outpatients and inpatients

The Working Alliance Inventory-Short Revised (WAI-SR) is a recently refined measure of the therapeutic alliance that assesses three key aspects of the therapeutic alliance: (a) agreement on the tasks of therapy, (b) agreement on the goals of therapy and (c) development of an affective bond. The WAI-SR demonstrated good psychometric properties in an initial validation in psychotherapy outpatients in the USA. The generalizability of these findings is limited because in some countries a substantial portion of individual psychotherapy is delivered in inpatient settings. This study investigated and compared the psychometric properties of the WAI-SR in German outpatients (N = 88) and inpatients (N = 243). In both samples reliability (alpha > 0.80) and convergent validity with the Helping Alliance Questionnaire were good (r > 0.64). Confirmatory factor analysis showed acceptable to good model fit for the proposed Bond-Task-Goal model in both samples. Multi-group analysis demonstrated that the same constructs were measured across settings. Alliance ratings of outpatients and inpatients differed regarding the overlap of alliance components and the magnitude of the alliance ratings: The differentiation of the alliance components was poorer in inpatients and they reported lower alliances. Unique aspects of the alliance in inpatient treatment are discussed and a need for further research on the alliance in inpatient settings is pointed out. Overall, the WAI-SR can be recommended for alliance assessment in both settings.

The Language of Political Conflict: A Logico-Semantic Approach

A semantic approach towards political conflict first emerged in the 1930s and provides the methodological foundations for the description of political conflicts, in particular as the correlation between the language of description and reality. Any military or political confrontation presupposes axiological, conceptual and ideological confrontation. The form of adequate description can only be comprehended if the characteristic features of its language (structure) and thesaurus are revealed. Admitting the possibility of different descriptions implies the necessity of analysing this possible ambiguity, i.e. the characteristic features of the language which enable us to form various statements, including mutually exclusive ones. The insoluble task of finding a middle ground between the viewpoints of the conflicting parties should be replaced by soluble procedures of explaining and assessing the conflicting axiologies. For the description of conflict situations, when it is essential to represent various positions within a uniform system, an apparatus of model semantics seems to be the most appropriate one both for generating alternatives and for bringing them together in a modal system of a world in which procedures of transition from one world to another (i.e. the transworld compatibility between them) are also reflected. Reality is reconstructed not as a sort of middle ground between the mutually exclusive approaches nor as their sum, but as a result of the overlapping of various worlds and the procedures of transition from one state of affairs to another. The description of a conflict is therefore seen as a system of worlds connected by modal relations, with a system of worlds emerging as a reality to be described. This approach makes it possible to describe the processes from the points of view of the participating parties and, at the same time, to reveal their basic attitudes. The main idea of this research is shown by the problems analysed: the description of conflict as methodology; language and behaviour (general problems of semiotic description), the logico-semantic analysis of the notions of "problem and conflict", "Genesis and Chronology", "the recurrent model of the (historical) explanation and interpretation of the conflict". Zolyan used data on the Karabagh conflict to demonstrate the dependence of the structure of semio-cultural codes on current political development and considered post-soviet history as a semio-cultural problem. He sought to consider and reveal the logic of manipulations with history, and proposed the logic of preferences as a possible instrument for achieving compromise.

The cloning and expression of myogenin, a gene regulating myogenesis

Expression of the differentiated skeletal muscle phenotype is a process that appears to occur in at least two stages. First, pluripotent stem cells become committed to the myogenic lineage. Although undifferentiated and capable of continued proliferation, determined myoblasts are restricted to a single developmental fate. Upon receiving the appropriate environmental signals, these determined myoblasts withdraw from the cell cycle, fuse to form multi-nucleated myotubes, and begin to express a battery of muscle-specific gene products that make up the functional and contractile apparatus of the muscle. This project is aimed at the identification and characterization of factors that control the determination and differentiation of myogenic cells. We have cloned a cDNA, called myogenin, that plays an important role in these processes. Myogenin is expressed exclusively in skeletal muscle in vivo and myogenic cell lines in vitro. Its expression is sharply upregulated during differentiation. When constitutively expressed in fibroblasts, myogenin converts these cells to the myogenic lineage. Transfected cells behave as myogenic tissue culture cells with respect to the genes they express, the way they respond to environmental cues, and are capable of fusing to form multinucleated myotubes. Sequence analysis showed that this cDNA has homology to a family of transcription factors in a region of 72 amino acids known as the basic helix-loop-helix motif. This domain appears to mediate binding to a DNA sequence element known as an E-box (CANNTG) essential for the activity of the enhancers of many muscle-specific genes.^ Analysis of myogenin in tissue culture cells showed that its expression is responsive to many of the environmental cues, such as the presence of growth factors and oncogenes, that modulate myogenesis. In an attempt to identify the cis- and trans-elements that control myogenin expression and thereby understand what factors are responsible for the establishment of the myogenic lineage, we have cloned the myogenin gene. After analysis of the gene structure, we constructed a series of reporter constructs from the 5$\prime$ upstream sequence of the myogenin gene to determine which cis-acting sequences might be important in myogenin regulation. We found that 184 nucleotides of the 5$\prime$ sequence was sufficient to direct high-level muscle-specific expression of the reporter gene. Two sequence elements present in the 184 fragment, an E-box and a MEF-2 site, have been shown previously to be important in muscle-specific transcription. Mutagenesis of these sites revealed that both sites are necessary for full activity of the myogenin promoter, and suggests that a complex hierarchy of transcription factors control myogenic differentiation. ^

How nice is good for patients and for therapy outcome? The role of confrontation in the process of psychotherapy

It is well established that the therapeutic relationship contributes about as much to therapy outcome as 'technical' intervention. Furthermore, it follows clear prescriptive concepts in the same manner as technical interventions do. 'Motive Oriented Therapeutic Relationship' is such a concept for establishing a solid basis for whatever therapeutic work the patients' problems require (Grawe, 1980, 1992; Caspar, 1996). Yet, the therapeutic relationship doesn't explain everything because other factors play a significant role too. Previous studies showed that outcome is clearly better when therapists achieved a generally high quality of a therapeutic relationship when they did not shy away from possibly threatening interventions such as confrontations. This ratio of a fruitful alliance and marginally present confrontations in the same session also showed significant correlations with patient's assessment of alliance and progress in therapy (Figlioli et al., 2009).Aim: The current state of research in the field does not give any answers to questions like how good and bad confrontations can be characterized or what role does the intensity, respectively frequency of confrontations play in the process of psychotherapy. Methods: A sample of 80 therapies of 3 sessions each representing either good or bad outcome was judged moment by moment by independent raters if and how therapists used confrontative interventions. Results: Preliminary analyses show that successful confrontations are explicitly uttered, short but intense, related to important patients goals in therapy and embedded in prior complementarity. Discussion: The results will be discussed in terms of their implications for the clinical daily work.
