Subjective Performance Evaluation in the Public Sector: Evidence from School Inspections

This paper investigates the effects of being evaluated under a novel subjective assessment system where independent inspectors visit schools at short notice, disclose their findings, and sanction schools rated fail. I demonstrate that a fail inspection rating leads to test score gains for primary school students. I find no evidence to suggest that fail schools are able to inflate test score performance by gaming the system. Relative to purely test-based accountability systems, this finding is striking and suggests that oversight by evaluators who are charged with investigating what goes on inside the classroom may play an important role in mitigating such strategic behavior. There appear to be no effects on test scores following an inspection for schools rated highly by the inspectors. This suggests that any effects from the process of evaluation and feedback are negligible for nonfailing schools, at least in the short term.
Thermoelastic properties of MgSiO3 perovskite using the Debye approach

Abstract MgSiO3 perovskite is shown to be a Debye-like mineral by the determination of specific heat, CV, entropy, S, and thermal pressure, ΔPTh, using the Debye theory up to 1800 K. Sound velocities and bulk moduli at ambient conditions published by Yeganeh-Haeri were used to find the ambient acoustic Debye temperature, ΘacD. The variation of ΘacD with T was assumed to be a curve parallel to the ΘacD vs. T curves previously found for Al2O3, MgO, and MgSiO3, enabling ΘacD (T) to be given up to 1800 K. To determine CP, the thermal expansivity, α, and the isothermal bulk modulus, KT, are needed. After considering several sets of α(T), the α(T) data of Funamori and his colleagues were chosen. Using the ambient KT and the values of (მKT /]T)P vs. T reported by Jackson and Rigden, KT(T) up to 1800 K was found. Then CP(T) up to 1800 K was found assuming quasiharmonicity in CV. The data behind the CP(T) calculation are also sufficient to find the Grüneisen parameter, γ(T), and the Anderson-Grüneisen parameters, δT and δS, up to 1800 K. The value of q = (მ ln γ/] ln V)T was found, and with γ and ρ, ΔPTh vs. V and T was determined. The three sound velocities, vs, vρ, and vb = √KS/ρ, were then determined to 1800 K. From vs and vρ, Poisson’s ratio and the isotropic shear modulus, G, were found to 1800 K. MgSiO3 perovskite is one of a small, select group of Debye-like minerals for which thermoelastic properties and the equation of state (EOS) are calculable from acoustic data.
EFFECT OF CROSSING FAYOUMI AND RHODE ISLAND RED ON GROWTH PERFORMANCE , EGG AND REPRODUCTIVE TRAITS UNDER EGYPTIAN CONDITIONS

This study was conducted to evaluate body weights, average daily gain (ADG), relative growth rate (RGR), average egg weight, hen day egg production% (HDEP%), hen housed egg production% (HHEP%), age at sexual maturity, body weight at sexual maturity, fertility%, scientific and commercial hatchability percentage in a complete 2x2 diallel crossbreeding experiment [Fayoumi and Rhode Island Red (RIR)]. RIR showed significant (p ≤ 0.05) higher body weight, ADG, RGR, age at sexual maturity and body weight at sexual maturity (1898.76 g, 9.04 g, 19 3.95%, 144.66 day and 1559.05 g, respectively) compared other genotypes. In addition, RIR recorded the highest egg weight, fertility percentage, scientific and commercial hatchability percentage (44.28 g, 85.59%, 94.91% and 81.49%, respectively). While Fayoumi male×RIR female crossbred recorded the highest significant estimate for HDEP % and HHEP % (54.41 and 51.65%).
Analysis of Angiogenesis During Mouse Embryo Implantation

Uterine receptivity and embryo implantation depend on local induction of angiogenesis and vascular permeability. Poor uterine receptivity has been implicated in implantation failure; however, relatively little is known about the mechanism that underlies endometrial vascular hyperpermeability in implantation sites. Here we show that contrast-enhanced (CE)-MRI and fluorescence microscopy using biotin-BSA-GdDTPA allowed high-resolution detection and quantitative assessment of mouse embryo implantation sites as early as embryonic day 4.5 (E4.5), and subsequent vascular expansion at E5.5. Vessel permeability, but not blood volume, was significantly elevated in E4.5 implantation sites relative to nonimplanted uterus, showing that elevation of vascular permeability is a very early response preceding E4.5. A significantly increased blood volume was detected by MRI and fluorescence microscopy in implantation sites between E4.5 and E5.5. On the other hand, despite the increase in blood volume, implantation sites showed only a small nonsignificant further increase in vascular permeability during these 2 days, demonstrating the rapid dynamics of vascular remodeling during the early days of pregnancy. Functional imaging by MRI, as reported here, allows multiparametric measurement of angiogenesis during normal mouse implantation and would facilitate the application of MRI to evaluate involvement of the vasculature in mouse models of impaired implantation.

ENERGY AND STABILITY ANALYSIS OF BIPED LOCOMOTION

This paper presents energy and stability functions, integrating the stability parameters of the Zero Moment Point (ZMP) classed bipeds where stability parameters are the positions of Center of Mass (CoM) and ZMP respectively. The Energy function is derived using the concept of Orbital Energy and is optimized using Real Coded Genetic Algorithm to produce an optimum set of walk parameters, which consumes minimum energy, during walking. A Stability function is also proposed, which is obtained by modifying the pre-existing ZMP trajectory. The ZMP trajectory is modified in such a manner, that it remains at the center of the convex hull, not only during the single support phase, but also during the transition of the robot from the Double Support Phase (DSP) to Single Support Phase (SSP) and vice-versa. The analytical results show that, when the energy function is optimized, the stability of the robot decreases. Similarly, if the stability function is optimized, the energy consumed by the robot increases. Thus, there is a clear trade-off between the stability and energy functions.
Pattern of Adverse Drug Reactions and its Potential Impact on Drug Resistant Tuberculosis Patients at a Tertiary Care Teaching Hospital in Western India

Medicines are double edged sword that may result into beneficial as well as undesirable/harmful effects like Adverse Drug Reactions (ADRs) [1]. They are important cause of morbidity and mortality in patients accounting for about 100,000 deaths annually and are estimated to be 4th to 6th largest cause of death in USA [2]. Tuberculosis (TB) is the world’s second commonest cause of death from infectious disease, after HIV/AIDS and India accounts for nearly 1/3rd of global tuberculosis burden. Out of the 8.6 million TB cases worldwide, 2.2 million (25%) cases are in India, making India the country with highest TB burden [3]. Several patient and drug factors has led to resistance to first line anti TB drugs resulting into Multi Drug Resistant Tuberculosis (MDR-TB) & Extensively Drug Resistant Tuberculosis (XDR-TB) [4]. The incidence of ADRs with anti-tubercular drugs is varies from 5% to 50% requiring either modification of treatment or stoppage of the drug therapy [5]. In addition, ADRs can lead to frequent treatment interruption and results into avoidable morbidity, drug-resistance, treatment failure and reduced quality of life. Often the ADRs are mild to moderate in nature and initiate with warning signals which needs to be captured by close monitoring of the patients [6]. Whereas, ADRs, which are serious and require interventions, are reported or noticed late in course of therapy and these ADRs may be irreversible resulting in disability or permanent damage. Therefore, ADRs during the course of anti-tubercular treatment are of significant medical importance and should be routinely monitored. In view of multi drug therapy with high rate of serious and irreversible toxicity and long duration of treatment, MDR-TB & XDR-TB being of national importance, the present study was conducted with following aims and objectives to evaluate ADRs for clinical spectrum, risk factors, outcome and analyze specific organ toxicity in the patients of drug resistant TB.

Predicting Query Execution Time using Statistical Techniques

Predicting query execution time is crucial for a number of tasks in database systems such as query scheduling, progress monitoring and costing during query optimization. Query optimizers uses two separate estimation models to find an optimal plan to execute a query a) selectivity estimators to predict the number of input tuples for each operator node of a query plan tree b) cost model to derive execution cost for a given plan. Significant errors occur in estimation of execution time of a query as a result of errors in selectivity estimates as well as inaccuracies in cost modeling [15]. In this work we are trying to minimize the error in the prediction of query execution time which occurs because of inaccurate cost model in the current optimizer of PostgreSQL database. We built a learning based cost model as opposed to traditional analytical models which are predominant in the current optimizer. We chose learning technique over analytical methods because it can capture operator interactions that happen within the query plan. A modeling technique was proposed previously [13] to learn query execution behavior at a fine-grained operator level. Combining this with a different learning technique, we are able to produce significantly better estimates than state of art the technique for a set of (test set) benchmark queries. We evaluate our approach using the TPC-H [4] and TPC-DS [6] workload on PostgreSQL 9.6 [1].
Pathological Study of the Experimentally Visceral Gout in Nasiriya City Broilers

Pathological study (crossly and histologically) of experimentally induced of visceral gout syndrome was studied for 35 days after intake of high dietary calcium and protein concentration in Nassirya City Broilers. Forty healthy birds (aged 1 day) were used and divided into two groups. The first group had given normal diet {NCNP, 8.5g ca kg and 175g cp kg}, while the second group had given high concentration of dietary calcium and crude protein {HCHP, 30G CA KG AND 250G cp kg}. All birds at 35 days examined grossly and histopathologically. Typical visceral gout was induced by the HCHP in which caused severe kidney damage (failure of urinary excretion) leading to accumulation of urate crystals in various parts of the body like pericardium, peritoneum, air sacs and liver capsule. Distended ureters often containing white calcium urate calculi (uroliths), besides histological changes in the myocardium, kidney, and ureters.
ON THE EXISTENCE OF FORCED OSCILLATIONS OF RETARDED FUNCTIONAL MOTION EQUATIONS ON TOPOLOGICALLY NONTRIVIAL MANIFOLDS

Using a topological approach, based on the fixed point index theory for locally compact maps on metric ANRs, we prove the existence of forced oscillations for retarded functional motion equations defined on topologically nontrivial compact constraints, provided that the frictional coefficient is nonzero. We do not know if an analogous result holds true in the frictionless case. Dedicated to Fabio Zanolin on the occasion of his 60th birthday
Rheological Properties of Barbari Bread Containing Apple Pomace and Carboxy Methyl Cellulose

Fast staling of traditional bread is one of the reasons for bread wastes. This study was designed to investigate the effect of applied apple fiber and carboxy methyl cellulose on improve the rheological properties and staling of traditional barbari bread. The rheological properties of dough were evaluated using farinograph and extensograph. Bread staling test was applied by sensory evaluation during 1, 2, and 3 days. For this purpose, three different amounts of apple fiber (5%, 8%, and 11%) were dried in a cabinet dryer at 58oC as a powder as well as carboxymethyl cellulose (CMC) at 0.1%, and 0.5% (w/w) were added to the flour. A full factorial design used to arrange treatments. The results of farinograph showed that, the sample containing 11% apple fiber and 0.5% CMC showed higher water absorption capacity, lower degree of softening, and higher quality properties compared to control and also the other samples. The results of extensograph in the sample containing 11% apple fiber and 0.5% CMC indicated lower ratio and high energy for all three time ranges (45, 90, 135 min) as compared with other experimental samples. The results of the panelists indicated that the enriched breads containing 11% apple fiber and 0.5% CMC obtained highest bread score for overall acceptability. The results of this study demonstrated that the combination of high level of apple fiber and CMC in the barbari flat bread significantly retard staling on it and improved its rheological properties.

Eff ect of Long-term Freezing on Renneting Properties of Sarda Sheep Milk

Cold storage is a well-known strategy to limit concerns about seasonality for sheep dairy productions. Th e aim of this study was to investigate the eff ect of long-term freezing on milk renneting properties from the Sarda sheep, an autochthonous breed from Italy. Two-hundred milk samples from 50 pluriparous Sarda ewes were collected at monthly intervals throughout the lactation from April to July. Each sample of fresh milk was analysed for composition and subsamples were obtained and frozen for one, three and fi ve months. Renneting properties, both from the fresh and frozen subsamples, were achieved using the Formagraph instrument and results were submitted to a mixed model statistical analysis. Th e storage eff ect signifi cantly aff ected (P<0.01) the renneting parameters. A large amount of non coagulating subsamples was registered aft er a long-term frozen storage. Furthermore, milk clotting time was longer in frozen subsamples and curd fi rmness diminished aft er a freezing period of fi ve months. In conclusion, the remarkable decreasing of sheep milk renneting characteristics aft er frozen storage can predict a worse yield and quality of cheese-making and suggests that freezing of Sarda raw milk should be limited to shorter periods.
Firm Heterogeneity and the Two Sources of Gains from Trade Itai Agur

Recent empirical work identi es two main channels through which consumers bene t from trade. Trade liberalization lowers prices, while it raises product variety. This paper develops the rst model that connects both channels and interprets their interaction. It shows that heterogeneity in rm productivity is the source behind both. Upon liberalization e¢ cient exporters enter, pushing out the least e¢ cient domestic rms. Two countervailing forces emerge, both stylized facts. Liberalization leaves a more concentrated market. But exporters o¤er more variety than the rms that they replace. Remarkably, total variety unambiguously increases. Exploration of comparative statics leads to an intuitive explanation.

Measurement of the 12 C + 12 C Fusion Cross Section at Sub-Barrier Energies

The goal of nuclear astrophysics is to understand the nuclear processes which power the stars and synthesize heavier elements. One important nuclear process is the 12C+12C fusion occurring in massive stars. The 12C+12C fusion produces 24Mg which can decay to 20Ne or 23Na via particle evaporation. Most of the residues may emit gamma radiation that can be detected using a gamma detector. We have studied the 12C+12C fusion reaction within the center of mass energy range of 4.1 MeV to 6.5 MeV by detecting the 440 keV and 1634 keV gamma lines using a germanium detector. The total fusion reaction cross section is determined after correcting decay branching ratios and summing effect.
High Pressure Structural Instability and Thermal Properties of Rutile TiO 2 from First-principles

We report a first-principles calculation to investigate the structural instability of rutile TiO2. The high pressure structural parameters are well reproduced. The calculated phonon dispersion curves agree with experiments at zero pressure. Under compression, we capture a large softening around Γ point, which indicates the structural instability. From the high pressure elastic constants, we find that the rutile TiO2 is unstable when the applied pressure is larger than 17.7 GPa. Within the quasi-harmonic approximation, the thermal equation of state, thermal expansion coefficient, bulk modulus, and entropy are well reproduced. The thermal properties confirm the available experimental data and are extended to a wider pressure and temperature range.
SHORT-RANGE ENSEMBLE FORECASTING

Short range forecasts do not use any probabilistic information. Although such forecasts are more and more skilful, some events remain unpredictable. Météo-France wishes now to use probabilistic forecasts at short range in order to get an assessment on extreme events risks. At the time being, ensemble forecasting seems to be the more simple and efficient tool to achieve these goals. Ensemble prediction is already used for medium range forecasting (Molteni et al. 1994 ; Toth and Kalnay, 1997). However, methods used in such ensembles can not be directly applied for the short range forecasting (Brooks et alt., 1995). Research has already been performed in this area and a short range ensemble system is operational at NCEP (Tracton et al. 1998; Stensrud et al. 1999). We are presenting here the description of an experimental ensemble developped at Météo-France in the PEACE (Prévision d’Ensemble A Courte Echéance) project. This ensemble is devoted to detect rare severe events such as storms in the short range (24-48h). Emphasis is put on assessing skill of predicting strong mean sea level pressure gradient probabilities.
Ultrasound-Guided Injection of Platelet-Rich Plasma and Hyaluronic Acid , Separately and in Combination , for Hip Osteoarthritis : A Randomized Controlled Study

Background: The effectiveness of intra-articular platelet-rich plasma (PRP) injections has been evaluated in knee chondroplasty and osteoarthritis (OA); however, little evidence of its efficacy in hip OA exists. Purpose: To compare the therapeutic efficacy of autologous PRP, hyaluronic acid (HA), or a combination of both (PRP+HA) in hip arthritis (OA). Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Patients aged between 18 and 65 years who were treated with outpatient surgery and who had hip OA and pain intensity at baseline of . 20 on a 100-mm visual analog scale (VAS) were recruited for this study. Exclusion criteria were extensive surgery; presence of excessive deformities; or rheumatic, infective, cardiovascular, or immune system disorders. The primary outcome measure was a change in pain intensity as assessed by the VAS at 2, 6, and 12 months after treatment. Secondary outcome measures were the Harris Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and concentration of growth factors in PRP and their correlation with clinical outcomes. Clinical outcomes were evaluated by assessors and collectors blinded to the type of treatment administered.
Habitual Green Tea Intake and Effects on Blood Glucose and Blood Lipids of Diabetic Rats

The effects of green tea on blood glucose and blood lipids were evaluated on alloxan-induced diabetic rats. The rats were grouped into four treatment groups: DC (diabetic group fed with rat feed and water), CON1 (diabetic group fed with rat feed and 1g/100ml of green tea intake), CON2 (diabetic group fed with rat feed and 2g/100ml of green tea intake) and CON3 (diabetic group fed with rat feed and 6g/100ml of green tea intake). The tea was brewed in boiling water for two minutes, cooled and then served. Feed, water and green tea were provided ad libitum for the respective groups for 21days. The blood glucose was determined every seven days from the day of confirmation of diabetes to the end of the experiment while the lipid analysis was carried out at the end of the experiment. The results obtained showed that green tea did not have any reduction effect on blood glucose at 1g/100ml and 2g/100ml of tea intake. It caused 0.05% reduction in blood glucose at 6g/100ml of tea intake. However,it caused significant reduction in total cholesterol, triglyceride, LDL-cholesterol and LDL/HDL ratio.
Photon and π 0 electroproduction in Jefferson lab Hall A ( 6 GeV experiments )

Generalized Parton Distribution (GPDs) are universal functions which provide a comprehensive description of hadron properties in terms of quarks and gluons. GPDs can be accessed experimentally with hard exclusive processes such as Deeply Virtual Compton Scattering (DVCS) and deeply virtual π0 production. Two experiments were performed in the Hall A of Jefferson Lab to measure the unpolarized cross sections of these two processes off the proton and off the neutron in the valence region (xB=0,36) at Q2 ≈2 GeV2. After a brief description of the experimental setup, the DVCS off the proton results will be discussed and interpreted as being unexpectedly sensitive to gluons. Then, the longitudinal/transverse separation of the π0 electoproduction cross sections, showing a dominance of the transverse terms, will be presented. Finally, an estimation of the quarks up and down contributions to the π0 electroproduction cross sections, by combining the proton and the neutron measurements, will be shown.
