I can see clearly now the wall Is gone: Situated Professional Learning in a Collaborative Innovative Learning Environment

The development of effective collaborative teacher practice within Innovative Learning Environments (ILEs) in primary schools forms a critical component that might underpin how successfully they operate. For many teachers, this shift into new and shared spatial settings may well coincide with increased levels of openness, visibility, deprivitisation of practice and opportunity to learn from their colleagues. Physical proximity, however, does not guarantee this learning, although professional exposure is perhaps more inherently assured. In such an environment, where does the difference lie between seeing and observing? And what role does feedback play between colleagues? ‘What’s working’ can perhaps therefore be constructed in terms of predominant cultural conditions, shared understandings, and teachers’ capacities to ‘be comfortable being uncomfortable’. This article draws on material from a wider study on teacher collaboration in ILE, and presents findings from data conducted in one of the New Zealand primary schools case study sites. It utilises data collected through interviews with principals and teachers, and observations of teacher teams practicing in ILEs. It reflects the notion that while spatial proximity may well present opportunities for teachers, it also presents complex challenges at the professional, social, and cognitive level.
Mutually consistent revealed preference bounds

Revealed preference restrictions are increasingly used to bound demand responses and as shape restrictions in nonparametric estimation exercises. However, the restrictions imposed are not su? cient for rationality when predictions are made at more than a single price regime. We highlight the nonlinearities in revealed preference restrictions and the nonconvexities in the set of predictions that arise when making multiple predictions. We develop a mixed integer programming characterisation of the problem that can be used to impose rationality on multiple predictions. The approach is applied to the UK Family Expenditure Survey to recover jointly rational nonparametric estimates of income expansion paths.
Attacker's advantages in a homogeneous market: The case of GSM

Abstract This article deals with the market entry and competitive strategies of two third entrants into the Western European GSM market: The Greek mobile communications operator Cosmote and the German operator E‐Plus. Starting point of our research is the analysis of the entire Western European GSM market, which shows a broad variance in performance indicators of the operators although the market characteristics regarding the product, the supply and the demand side are quite homogeneous. In order to explain the performance variance and the success of late movers we examine the market entry and competitive strategy of the most successful third entrant in Western Europe, Cosmote, and contrast this case to E‐Plus. The market environment and the company characteristics of both companies are similar, but their performance differs significantly. The major results of our analysis are (1) that quality of service, including particularly the network coverage at launch and in the first stage, is more important than time to market, (2) that the image of an operator depends strongly from the customer's perception in the starting phase, and (3) that the commitment in combination with the resources of the shareholders are crucial for the operators’ success.
Serological Relationships between Strains of Coryneform Bacteria Responsible for Annual Ryegrass Toxicity and Other Plant-Pathogenic Corynebacteria

Immunodiffusion and an enzyme-linked immunosorbent assay (ELISA) were used to reveal serological relationships between coryneform bacteria responsible for annual ryegrass toxicity (ARGT) and other plant-pathogenic corynebacteria, particularly those associated with similar diseases of grasses, Clavibacter iranicum, Clavibacter rathayi, and Clavibacter tritici. Antisera were raised in rabbits against one strain each of C. iranicum, C. rathayi, C. tritici, and the ARGT bacterium. The antisera were tested against 26 strains belonging to that group of species and one strain each of eight other species of plant-pathogenic corynebacteria. Immunodiffusion with antiserum against the ARGT bacterium did not show cross-reactions with any of the other species tested, whereas, antisera against C. iranicum, C. rathayi, and C. tritici all showed some heterologous cross-reactions. The ELISA revealed cross-reactions undetected by immunodiffusion and allowed the organisms to be grouped by hierarchical cluster analysis. The results indicate that coryneform bacteria pathogenic to Lolium rigidum and responsible for its toxicity to livestock are serologically distinct from the other plant-pathogenic corynebacteria causing similar diseases of grasses. Amino acid analysis of the ARGT bacterium cell wall revealed the presence of 2,4-diaminobutyric acid, indicating that this bacterium should be classified in the genus Clavibacter.
The Relationship of Cultural Similarity, Communication Effectiveness and Uncertainty Reduction.

The purpose of this study was to investigate the relationship ofcultural similarity/dissimilarity, communication effectiveness and communication variables associated with uncertainty reduction theory. The aub3ects were a multinational groups of students living on an "international floor" in a dormitory at a state university and an unrelated group of U.S. students living in another dormitory. Multivariate analysis of variance was used to test the relationship of cultural similarity of roommates and communication effectiveness of roommates on self-disclosure, interrogation, deception detection, attraction, attitude similarity, shared communication networks, and attributional confidence. Results indicate that communication effectiveness had a significant multivariate effect on the dependent measures. Cultural similarity produced no effect, nor was there an interaction affect between cultural similarity and communication effectiveness. The findings suggest that degree of communication effectiveness and stableness of the roommate relationship are more important predictors of communication than is the intraor intercultural nature of the roommate pair.
A New Method for Recognition of Arcing Faults in Transmission Lines using Wavelet Transform and Correlation Coefficient

In this paper a novel method based on discrete wavelet transform and correlation coefficient is presented for distinguishing between arcing and permanent faults. The algorithm includes offline and online processing. In the offline, discrete wavelet transform is used to decompose typical faulted phase voltage waveforms during arcing faults. An index is then defined and computed. The index is based on the normalised energy of detail coefficients at resolution levels 1 to 14. The online processing consists of capturing the faulted phase voltage waveform using a 20 kHz sampling rate, and decomposing it by db4. Finally, arcing faults are distinguished from permanent faults based on correlation coefficient of the computed index of the pre-stored typical arcing faults and a recorded indistinct signal. The effectiveness of the approach has been tested for numerous arcing and permanent fault conditions on a transmission line using the Electromagnetic transient Program (EMTP) software tool. The simulation results show the capability of the proposed method in distinguishing between arcing faults from permanent faults.

Playing below the poverty line: Investigating an online game as a way to reduce prejudice toward the poor

A plethora of research indicates that viewing media can reduce prejudice. Emerging work on computer gaming shows that games can also influence social attitudes. The present studies investigated the influence of an interactive computer game about living in poverty on attitudes and beliefs about the poor. Playing the poverty game was compared to playing a control game and merely observing the poverty game. In Study 1, playing an interactive poverty game did not influence attitudes while watching someone else play the game increased positive attitudes, empathic concern, and support for government-funded anti-poverty policies. In Study 2, meritocracy beliefs moderated the influence of the game; people lower in meritocracy showed less positive attitudes toward the poor after playing the poverty game. This effect was mediated by an increase in the belief that poverty is personally controllable. Future directions for and implications of studying the unique intergroup effects of games are discussed.
THE INFLUENCE OF SHAREHOLDER VOTING RIGHTS ON INTERNAL CONTROL MECHANISMS: A COMPARATIVE STUDY OF PUBLICLY TRADED FIRMS IN PORTUGAL AND UNITED KINGDOM

This work analyses the role of shareholder voting rights on the adoption of internal control mechanisms by firms from both a small emerging and developed economies. It also studies the influence that sector of activity and company size have on these mechanisms. The sample is comprised of publicly traded companies from Portugal and the United Kingdom. Data analysis using path analysis and multiple linear regression shows that shareholder ownership has a weak influence on control mechanisms. It also reveals that sector of activity and company size have differing influences on control mechanisms in differing contexts.
A LOOK INTO NATIVE SPEAKERS ’ SPEECH MARKERS , OR DISCOURSE MARKERS ?

Based on Speech Production and Genre studies, I supply real data and describe informal interviews with native English speakers collected in the Speak up Magazine, a publication dedicated to Brazilian English speakers. Speech markers, or also known as discourse markers, which are used to signal different functions in conversation and commonly used by native speakers (NS) comprising the patterning of natural talk were highlighted. I show that in informal interviews in English, NS use, although not always, the discourse markers ‘you know’ and ‘I mean’ to give a continuum in the flow of speech and to maintain a connection with the interlocutor. Finally, I discuss the value of fluency features that do not normally contribute with additional lexical information and present the contributions of this study to the teaching of English as a foreign language, to didactic material production in real contexts, and for social relations. KEY-WORDS: interviews – discourse/speech markers genres
Applikation von fermentierter Soja bei Krebspatienten zur Verminderung von Kachexie und Erhöhung der Apoptose - eine prospektive Pilotstudie

Application of Soy in Cancer Patients to Reduce Cachexia and Increase Apoptosis by Fermental Soy – a Prospective Pilot Study. Clinically, cachexia manifests with excessive weight loss in the setting of ongoing disease, usually accompanied by muscle wasting. It affects more than 5 million persons in the United States alone: Aids, cancer, rheumatoid arthritis. Other causes of weight loss include anorexia, sarcopenia, and dehydration. The major cause described in the scientific literature appears to be cytokine excess, particularly increase of IL-6 and TNF-α. Both nutritional support and anorexigenic agents play a role in the management of cachexia. A fermented soy product available in Germany and Austria, which was marketed in the US in 1987 for reduction of symptoms accompanied in cancer patients, was investigated. It was shown in a small-scale prospective study in prostate, mammary and ovarian cancer patients that a fermented soy product could reduce depression, stress and cachexia which were unresponsive to conventional therapy. Significant increase of body weight was achieved. Apoptosis markers in disseminated tumor cells like BAX/Bcl2-ratio, cell cycle inhibitor p21 and anti-proliferation factor Estrogen Receptor beta (ER-β) gene expressions were increased in prostate cancer and ovarian cancer patients. Breast cancer patients did show increased cell cycle inhibitor p21, however no increase in apoptosis or ER-β-expression. Results may confirm our assumption that cachexia and reduced apoptosis are linked via NFκB, at least for prostate and ovarian cancer patients. Results have to be confirmed in a larger clinical trial.

Evaluating Correlation and Factor Analysis of Morphological Traits in Potato Cultivars in Fall Cultivation of Jiroft Area

4 Abstract: In order to evaluate and classify morphological traits of Potato cultivars in fall cultivation of jiroft area, 22 Potato cultivars and experiment in randomized complete block design with three replications, was done in Jiroft Agricultural Research Center. Correlation coefficient showed that tuber weight and harvest index have positive and significant correlation with tuber yield. Factor analysis based on principal component analysis method and varimax rotation indicated that three important factors accounted for about 80.05 percent of the total variation among traits. The first factor assigned 33.29 percent of total variation between traits and was significantly related with tuber yield. Therefore, this factor was regarded as tuber yield factor. Other factors accounted for 30.48 and 16.28 percent of variation between traits and were entitled as stolon length factor and negative factor for diagonal height, respectively.
Potential Bioactive Compounds Isolated from Boesenbergia rotunda as Antioxidant and Antimicrobial Agents

Objective: This study was conducted to identify some bioactive compounds of Boesenbergia rotunda rhizome and to test as antioxidant and antimicrobial agents. Methods: The milled dried rhizome of B. rotunda (5kg) was extracted exhaustively with ethanol. The ethanol extract was partitioned three times by n-hexane, chloroform, and ethyl acetate respectively. Each fraction was fractionated by vacuum liquid chromatography (VLC) and then purified by column chromatography gravitation. Structural identification of all pure compounds were elucidated based on spectroscopic methods (UV, IR, and NMR). The antioxidant activity was tested by 2,2-diphenyl-1-picrylhydrazyl (DPPH). Antimicrobial character was screened for activities againts pathogenic bacteria i.e. Escherichia coli ATCC-11229, Staphylococcus aureus ATCC-25923, Staphylococcus epidermidis FNCC-0048, and Streptococcus mutans by the disk-diffusion method. The assay was done in triplicate, and chloramphenicol was used as the positive control. Results and Discussion: From ethanol extract of B. rotunda three known compounds of flavanones, namely 2’,4’-dihydroxy-6-methoxychalcone (compound-1), 5-hydroxy-7methoxyflavanone (compound-2), and 5,7-dihydroxyflavanone (compound-3) were isolated. The ethanol extract of B. rotunda and the three isolated compounds -1,-2, and -3 showed an antioxidant activity with the IC value of 92.64; 46.66; 62.84, and 62.66 μg/mL, respectively. The zone of inhibition of extract and the three isolated compounds showed moderate activity against Escherichia coli ATCC-11229, Staphylococcus aureus ATCC-25923, Staphylococcus epidermidis FNCC-0048, and Streptococcus mutans.The maximum zone of inhibition was 13.20±0.76 mm at the maximum concentration used (500 μg/mL) against Escherichia coli ATCC-11229, and the minimum inhibitory concentration(MIC) for each bacteria was found to be 0. 5μg/mL. Conclusion: The result of the study suggests that B. rotunda rhizome contains potential bioactive compounds which could be suitable for antioxidant and the treatment of various infections caused by Escherichia coli ATCC-11229, Staphylococcus aureus ATCC25923, Staphylococcus epidermidis FNCC-0048, and Streptococcus mutans.

Munich Personal RePEc Archive Profitability and Crisis in the South African Economy

Based on new quarterly estimates of the general rate of pro t over 19602016, this paper shows that the South African economy experienced two phase changes in the pace and rhythm of capital accumulation. The rate of pro t exhibits a cyclical tendency to fall, mainly driven by the tendency of capital intensity to rise. The economy experienced a crisis of absolute overproduction of capital in the mid-1980s. This crisis was not only characterised by stagnation in the mass of pro ts, it was also characterised by a halt in capital accumulation. Thereafter, the rate of pro t recovered primarily because of the fall in the capital-output ratio but it failed to reach the levels seen in the 1970s. We estimate that in 2012, the South African economy entered a new and on-going crisis of overproduction of capital characterised by stagnant pro ts and prolonged overaccumulation, which makes it impossible for economic growth to recover. Keywords: falling rate of pro t, capital intensity, overproduction of capital, overaccumulation. JEL Codes: B5, E11, O5
EFFECTS OF PIPER UMBELLATUM LINN. (PIPERACEAE) LEAVES EXTRACT ON ALUMINIUM CHLORIDE REPRODUCTIVE TOXICITY IN MALE RATS

Numerous studies found that aluminium has detrimental effects on body systems, including the reproductive one. Piper umbellatum, a plant used as spice and vegetable in the southern part of Cameroon, has been reported having many therapeutic properties such as antiinflammatory, analgesic, antioxidant and aphrodisiac. So, this study was undertaken to assess the effects of Piper umbellatum leaves extract on aluminium chloride reproductive toxicity in male rats and to perform the phytochemical screening of the extract. Rats first received aluminium chloride for 35 days. Then, for 60 days, rats were treated with Piper umbellatum aqueous leaves extract at the doses of 75 and 150 mg/kg. A libido test was performed the 55 th day. The 61 st day, rats were sacrificed and blood taken for biochemical analysis. Sexual organs were weighted. The epididymal sperm was collected for evaluation of sperm count and motility. The testis and the epididymis were homogenised for biochemical analysis. The testis and the epididymis were kept in the Bouin’s solution for histological analysis. The phytochemical screening revealed the presence of alkaloids, flavonoids and saponins in the extract. Aluminium caused a significant decrease in organ weight (p < 0.05), sperm count and motility (p < 0.05) and oxidative stress (p < 0.05). In addition, histological damages were observed in the testes and epididymis. Our results revealed that aluminium reproductive toxicity was reversed by Piper umbellatum extract WORLD JOURNAL OF PHARMACY AND PHARMACEUTICAL SCIENCES SJIF Impact Factor 6.647 Volume 6, Issue 6, 338-362 Research Article ISSN 2278 – 4357 Article Received on 14 April 2017, Revised on 04 May 2017, Accepted on 24 May 2017, DOI: 10.20959/wjpps20176-9379 *Corresponding Author Pr.

Fine‐grained dust rims in the Tagish Lake carbonaceous chondrite: Evidence for parent body alteration

Abstract— The Tagish Lake carbonaceous chondrite consists of heavily aqueously altered chondrules, CAIs, and larger mineral fragments in a fine‐grained, phyllosilicate‐dominated matrix. The vast majority of the coarse‐grained components in this meteorite are surrounded by continuous, 1.5 to >200 μm wide, fine‐grained, accretionary rims, which are well known from meteorites belonging to petrological types 2 and 3 and whose origin and modification is still a matter of debate. Texturally, the fine‐grained rims in Tagish Lake are very similar throughout the entire meteorite and independent of the nature of the enclosed object. They typically display sharp boundaries to the core object and more gradational contacts to the meteorite matrix. Compared to the matrix, the rims are much more finegrained and characterized by a significantly lower porosity. The rims consist of an unequilibrated assemblage of phyllosilicates, Fe,Ni sulfides, magnetites, low‐Ca pyroxenes, and forsteritic olivines, and are, except for a much lower abundance of carbonates, very similar to the Tagish Lake matrix. Electron microprobe and synchrotron X‐ray microprobe analyses show that matrix and rims are also very similar in composition and that the rims differ significantly from matrix and bulk meteorite only by being depleted in Ca. X‐ray elemental mapping and mineralogical observations indicate that Ca was lost during aqueous alteration from the enclosed objects and preferentially crystallized as carbonates in the porous matrix. The analyses also show that Ca is strongly fractionated from Al in the rims, whereas there is no fractionation of the Ti/Al‐ratios. Our data suggest that the fine‐grained rims in Tagish Lake initially formed by accretion in the solar nebula and were subsequently modified by in situ alteration on the parent body. This pervasive alteration removed any potential evidence for pre‐accretionary alteration but did not change the overall texture of the Tagish Lake meteorite.
Natural infection of Run1-positive vines by naïve genotypes of Erysiphe necator

The Run1 locus for dominant resistance to powdery mildew ( Erysiphe necator ) has been successfully introgressed into Euvitis from Vitis rotundifolia . In the current study, Run1 vines were hybridized with breeding lines at Cornell University, and the presence of the locus was assayed using the markers GLP1-12 and VMC8g9. Signs of powdery mildew were observed on 14 of 113 Run1 -positive seedlings in October 2010 in Geneva, N.Y. Severity of infection was lower for Run1 -positive than for Run1 -negative seedlings. Presence of mature cleistothecia suggested infection by at least two pathogen genotypes, which since V. rotundifolia is not grown within 800+ km of Geneva, N.Y. , evolved from a pathogen population naive to Run1 resistance. Therefore, caution in the deployment of the Run1 locus in new resistant cultivars is suggested so the effectiveness of Run1 does not diminish over time.
Development of a low-cost motorcycle riding simulator for emergency scenarios involving swerving

The development of advanced riding assistance systems requires the analysis of user reactions in emergency situations. Motorcycle riding simulators are an alternative to ‘on-road’ testing so that virtual environment dangerous scenarios can be investigated without risks for the participants. In this paper, we propose a process for validation of a low-cost motorcycle simulator characterized by, first, an elastic resistance on the steering input and, second, a counter-steering strategy. For this, 16 riders tested the simulator in different manoeuvres, including a cornering manouvre in a non-urban environment, a slalom manoeuvre and a lane-change manoeuvre. Objective evaluations and subjective evaluations showed that the simulator was realistic, in particular for investigating lateral avoidance scenarios. The development of suitable motorcycle simulators will significantly advance the field of motorcycle safety research.
