Leadership and motivation for improved academic performance in schools in low socio-economic contexts

Field: Social Sciences (Social Sciences)

Purpose This paper examines motivational practices and engagements of schools – through strategies developed by principals with the members of the school management team – to improve academic performance. Design/methodology/approach The research used an interpretive approach within a qualitative design in which schools were purposefully selected. In each of the sampled schools, individual interviews were conducted with the principal as well as a focus group with the school management team and another focus group was identified teachers. Findings The main findings reveal that school labelling (where schools are labelled as underperforming schools) as a public notice was identified as the main push towards intrinsic motivation, especially when positive results in learner performance are eventually achieved. Extra classes, teaching collaboration, monitoring and team building were some of the main strategies used. Efforts appear to focus on performance in Grade 12 examinations. Therefore, the study recommends that attention be spread across all grades as a long-term improvement plan for the education system. Furthermore, since these strategies have worked successfully, the national and the provincial education departments should consider developing plans for academic improvement based on these strategies. Research limitations/implications This research contributed to the understanding of school improvement in a specific context of low socio economic and societal context and schools are able to improve in spite of the challenging context. This is specifically in a developing country's context. More research can be conducted about the specific influence of intrinsic motivation and how extrinsic factors can become internalised as intrinsic motivation factors. Practical implications The findings from this project can provide leadership at schools with the necessary information and examples of what can be done to get teachers to improve the performance in a challenging context. The use of extrinsic as well as intrinsic motivational actions can provide the leadership with the necessary guidelines to implement in their schools. The appointment of principals with specific characteristics needed attention in policy as well as the practice of the appointment process. Originality/value The research is contributed to the knowledge of school improvement from a perspective of a developing country and is using motivational theories within this context. The limited literature which links motivation to the process of school improvement is advanced from ice perspective of low socio economic context in a developing country.

Constraint-induced breaking and restoration of ergodicity in spin-1 PXP\n models

Field: Physics and Astronomy (Physical Sciences)

Eigenstate Thermalization Hypothesis(ETH) has played a pivotal role in\nunderstanding ergodicity and its breaking in isolated quantum many-body\nsystems. Recent experiment on 51-atom Rydberg quantum simulator and subsequent\ntheoretical analysis have shown that hardcore kinetic constraint can lead to\nweak ergodicity breaking. In this work, we demonstrate, using 1d spin-1 PXP\nchains, that miscellaneous type of ergodicity can be realized by adjusting the\nhardcore constraints between different components of nearest neighbor spins.\nThis includes ETH violation due to emergent shattering of Hilbert space into\nexponentially many subsectors of various sizes, a novel form of\nnon-integrability with an extensive number of local conserved quantities and\nstrong ergodicity. We analyze these different forms of ergodicity and study\ntheir impact on the non-equilibrium dynamics of a Z2 initial state. We use\nforward scattering approximation (FSA) to understand the amount of\nZ2-oscillation present in these models. Our work shows that not only ergodicity\nbreaking but an appropriate choice of constraints can lead to restoration of\nergodicity as well.\n
Is nasogastric suction necessary in acute pancreatitis?

Field: Medicine (Health Sciences)

Fifty-eight patients with mild to moderately severe acute pancreatitis were randomly allocated to treatment with or without nasogastric suction (27 and 31 patients respectively). Intravenous fluids and pethidine hydrochloride were also given. The two groups were comparable clinically at the start of the study. There were no differences between the two groups in the mean duration of the following features: abdominal pain or tenderness; absence of bowel movements; raised serum amylase concentration; time to resumption of oral feeding; and days in hospital. Prolonged hyperamylasaemia (serum amylase greater than 0.33 mU/l) occurred in one patient in the suction group and in three patients in the non-suction group. A mild recurrence of abdominal pain after resumption of oral feeding occurred in three patients in the suction group and in two patients in the non-suction group. Two patients in the suction group developed overt consumption coagulopathy and two others pulmonary complications. No patient in the non-suction group had complications. The findings suggest that most patients with mild to moderately severe acute pancreatitis do not benefit from nasogastric suction. The procedure should be elective rather than mandatory in treating this condition.
Test of a Model Linking Employee Positive Moods and Customer Service Evaluations

Field: Business, Management and Accounting (Social Sciences)

This study developed a theoretical model that integrates two distinct perspectives on workplace emotions: the intrapersonal and the interpersonal (Grandey, 2008). We examined the mechanisms that underlie the previously observed association between the positive moods of employees and customer evaluations of service experiences. The results, based on 120 service transactions from a variety of service organizations in Taiwan, indicate that there exists an indirect relationship between employee positive moods and the emotional displays. In other words, employees experiencing higher positive moods in the workplace are more likely to express the authenticity of positive displays, that is mediated by the strategies of surface acting and the display of naturally felt emotions. Further, the results of the present study demonstrate that service employee used different emotional labor strategies such as surface acting and the expression of spontaneously felt emotions which resulted in different customer outcomes (i.e., customer satisfaction and loyalty intentions) through sincerely displaying desired positive emotions. We discuss the implications of our findings on scholarly research in the field of affect at work and suggest practical implications for service managers.
Evaluating the Effectiveness of Relational Marketing Strategies in Corporate Website Performance.

Field: Business, Management and Accounting (Social Sciences)

The study aligns marketing intelligence approaches with website performance assessment for evaluating the effectiveness of a company’s relational marketing strategies (RMS) in the performance of its corporate website. We develop a web mining based methodology that combines a classification procedure with discriminant analysis for analyzing clickstream data. Furthermore, we integrate managerial perspectives in investigating and interpreting customer website usage for determining RMS effectiveness. As a result, we are able to quantify the moderating effect of the website’s structure and content on the effectiveness of Internet based relational marketing (RM) efforts. The applicability of this approach is demonstrated by investigating RMS effectiveness in the performance of a software developer’s website. The results of our approach support website optimization and also enable customization for different relational marketing strategies. 1
Craters in the Telsen area, Chubut Province, Argentina: Satellite imagery digital processing techniques applied to surficial geology mapping

Field: Earth and Planetary Sciences (Physical Sciences)

Subcircular features, with crater morphology, developed in a volcano-sedimentary context, with diameters no greater than 2 km, were recognized in the vicinity of the Telsen locality, northeastern Chubut Province, Argentina. These structures are surrounded by tabular volcanic rocks of the Quiñelaf Formation with low radial-centrifugal dip, exhibit an external ring with dark visual levels enclosing topographic highs with mostly light visual levels. Surficial geological aspects of one of the larger structures in the area (S 42° 22’ 55’’, W 66° 49’ 15’’) were mapped from raster data at a scale of 1:3.000, following the stages of the photographic interpretation. Panchromatic and multispectral Spot images, and Google Earth image with 0.5 m. spatial resolution were used. Idrisi, Global Mapper, StitchMaps and Corel Draw software were used in the digital processing. The geological references of the area were obtained from the Telsen Geological map, herein georeferenced with Global Mapper. The frequency distribution histograms of the image windows of the different mapped sectors, allowed the generation of different contrast enhancements. Directional filters of the menu texture analysis of Idrisi permitted the identification of the oriented features. The images obtained herein, allowed the recognition of homogeneous units in terms of interpretation keys linked to the photo-analysis phase. Subsequent field observations contributed to the adjustment and to the final assignment of categories to each homogeneous unit (photo-interpretation last stage).The final map was compiled with the software Corel Draw, it was based on the synthesis image from the digital processing and referenced using Global Mapper. Deposits and fragments of basalt that constitutes the external ring of the crater along with different volcanic rocks, breccia and Chubut Group rocks fragments enclosed within the crater are mainly showed in this map. Also, deposits and dipping strata of the Chubut Group following the strike of the ring and outcrops of volcanic rocks in the central - south part of the mapped area were recognized. Detailed geophysical surveys detected magnetic anomalies in the SE part of the mapped crater. Several mechanisms such as magmatism, phreatomagmatism and/or bolide impacts constitute hypotheses related to the probable origin of these landforms.
Solid self-microemulsifying drug delivery system (S-SMEDDS) prepared by spray drying to improve the oral bioavailability of cinnamaldehyde (CA)

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The aim of this study was to prepare a solid self-microemulsifying drug delivery system (S-SMEDDS) of cinnamaldehyde (CA) by spray drying technique to improve the oral bioavailability of CA. The preparation of CA S-SMEDDS with maltodextrin as the solid carrier, a core-wall material mass ratio of 1:1, a solid content of 20% (w/v), an inlet air temperature of 150 °C, an injection speed of 5.2 mL/min, and an atomization pressure of 0.1 MPa was determined by using the encapsulation rate as the index of investigation. Differential scanning calorimetry (DSC) revealed the possibility of CA being encapsulated in S-SMEDDS in an amorphous form. The

Buckeye Poisoning of the Honeybee A Progress Report

Field: Agricultural and Biological Sciences (Life Sciences)

The poisonous effect of the California buckeye on the honeybee was shown to have a cumulative effect on the queen to the extent of either preventing the egg from hatching or so weakening the larva that it died soon after hatching. All queens of the same race or of hybrid stock were not affected alike as some showed greater resistance than others. The sap of the buckeye was shown to be poisonous to bees but no bees were observed to gather it after it had oozed from punctures made in the stems by lrbisia solani Heid.
Model selection for pressure-flow velocity relationships of cerebral arteries

Field: Medicine (Health Sciences)

Five different mathematical models of pressure-flow velocity relationships of the middle cerebral artery have been studied using 93 records of data obtained from 35 newborn babies. The models considered are based on a general autoregressive/moving average structure which can be translated into physical/haemodynamic analogs. Each model was fitted to individual heart beats of a sequence of 200 cardiac cycles and mean values, variability estimates, and model statistics were obtained for each record. Although all models studied are highly significant and accurate, considerations of parameter significance, variability and the nature of the clinical problem should determine the final choice of the most appropriate model for each application.< >

Enhanced amplified spontaneous emission performance through effective regulation of phase distribution in Ruddlesden–Popper perovskite films

Field: Materials Science (Physical Sciences)

Ruddlesden–Popper (RP) perovskites promise next-generation gain media for laser devices. However, most RP perovskite lasers are still suffering from inferior performance characteristics, such as inadequate energy transfer, unstable emission, and short lifetime. To address the above problems, high crystalline quality, compact, and smooth PEA 2 FA 2 Pb 3 Br 10 films with uniform phase distribution were successfully prepared by ionic liquid (IL) methylammonium acetate (MAAc) in an air environment. Compared with the PEA 2 FA 2 Pb 3 Br 10 film prepared by the traditional solvent dimethyl sulfoxide (DMSO), an enhanced amplified spontaneous emission (ASE) with a lower threshold of 58 µJ·cm −2 from the MAAc-treated film was obtained under nanosecond laser excitation. The transient absorption (TA) spectroscopy revealed that a uniform phase distribution and more efficient energy transfer processes were achieved in the PEA 2 FA 2 Pb 3 Br 10 -MAAc film, leading to an enhanced band-to-band spontaneous emission process. Furthermore, the films exhibited better stability, showing no signs of degradation under the 120 min pulsed laser pumping in air and stability of ASE spectra at even 95% humidity conditions. This study provides an important foundation for achieving high-performance optically pumped lasers based on the unique RP perovskites.

Laplacian Mesh Smoothing with Bilateral Weight for Characterization of Freeform Surfaces

Field: Computer Science (Physical Sciences)

In additive manufacturing, freeform surfaces are commonly used but difficult to be characterized due to their complex geometrical shapes. Therefore, it is preferable to remove the form in the first step. Freeform surfaces are widely represented by polygon meshes, especially triangular meshes. In cases where general freeform surfaces cannot be fitted with a geometrical form, the form of the surface can be estimated using a smooth version of the surface. The most widely used mesh smoothing method is Laplacian smoothing. Traditional Laplacian mesh smoothing techniques employ uniform, distance, or cotangent weights to discretize the Laplacian-Beltrami operator for each vertex but have limitations in preserving dimensions while effectively dealing with noise. This paper presents an innovative approach to enhance Laplacian mesh smoothing by using a bilateral weight for each vertex, thereby mitigating the limitations.
Evaluation of effect of food ingestion on bioavailability of cephalexin by moment analysis.

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The effect of food ingestion on the bioavailability of cephalexin in humans was investigated. The amounts of urinary excretion following single oral doses to healthy male subjects were determined by high-performance liquid chromatography, and the bioavailability was evaluated by means of moment analysis of excretion rate-time curves. The ingestion of test meals (high carbohydrate, high protein and high fat) delayed the excretion rate with the peaks approximately two-thirds lower and 1-1.5 hr later than that in fasting subjects, but did not affect the total excretion amounts. No significant difference was found among the test meals. The moment analysis indicated that the rate of bioavailability increased by an average of 71% following food ingestion without significant change in the extent of bioavailability.
Amphiphilic poly(ethylene glycol) gels and their swelling features

Field: Chemistry (Physical Sciences)

This article describes the preparation of poly(ethylene glycol) (PEG) ‐based gels for removal of both organic solvents and water through a clean synthesis process without using any initiator, catalyst, activator, or liquid medium. The synthesis of the gels is based on the condensation of different molecular weights of PEG macromolecules with the nine‐functional crosslinker tris[3‐(trimethoxysilyl) propyl] isocyanurate (ICS). Solid‐state 13 C and 29 Si cross‐polarization magic angle spinning (CPMAS) nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), and elemental analysis were used to characterize the prepared sorbents. Thermal properties of the synthesized sorbents were examined using thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The swelling capacities of the sorbents were determined by swelling tests in dichloromethane (DCM), tetrahydrofuran (THF), benzene, acetone, and toluene. The water absorbency of the PEG‐based sorbents is also investigated. The effect of the reaction time and reaction temperature on swelling features of the sorbents was studied systematically. The prepared PEG gels have high swelling ratios both in polar and nonpolar solvents. Copyright © 2015 John Wiley & Sons, Ltd.
Effects of Atmospheric Ozone on Microarray Data Quality

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

A data anomaly was observed that affected the uniformity and reproducibility of fluorescent signal across DNA microarrays. Results from experimental sets designed to identify potential causes (from microarray production to array scanning) indicated that the anomaly was linked to a batch process; further work allowed us to localize the effect to the posthybridization array stringency washes. Ozone levels were monitored and highly correlated with the batch effect. Controlled exposures of microarrays to ozone confirmed this factor as the root cause, and we present data that show susceptibility of a class of cyanine dyes (e.g., Cy5, Alexa 647) to ozone levels as low as 5-10 ppb for periods as short as 10-30 s. Other cyanine dyes (e.g., Cy3, Alexa 555) were not significantly affected until higher ozone levels (> 100 ppb). To address this environmental effect, laboratory ozone levels should be kept below 2 ppb (e.g., with filters in HVAC) to achieve high quality microarray data.
Heterogeneity of treatment response in bronchiectasis clinical trials

Field: Medicine (Health Sciences)

Introduction: Recent randomized clinical trials (RCTs) in bronchiectasis have failed to reach primary endpoints, suggesting a need to reassess how we measure treatment response. We aimed to determine patterns of response to treatment in bronchiectasis RCT and to study a new composite endpoint Methods: We evaluated treatment response in 3 RCTs that evaluated mucoactive therapy (inhaled mannitol), an oral anti-inflammatory/antibiotic (azithromycin) and an inhaled antibiotic (aztreonam). Treatment response was defined by change in the outcomes greater than the minimum clinically important difference (MCID). The composite endpoint was defined by one of 1) absence of exacerbation during follow-up, 2) improvement in quality of life (QOL) above the MCID and 3) improvement of FEV1 of ≥100ml. Results: Cumulatively the three studies included 984 patients. Response to treatment was heterogeneous in all trials. Improvement in QOL was not correlated to changes in FEV1 in the azithromycin and aztreonam trials (r=-0.17, p=0.1 and r=0.04, p=0.4) and weakly correlated in the mannitol trial (r=0.22, p<0.0001). Using the primary endpoints only the azithromycin trial showed a statistically significant difference versus placebo. Using a composite endpoint of clinical response, 82% of the patients receiving mannitol were responders vs 69% receiving placebo (p=0.002) and 81% of patients receiving azithromycin were responders vs 53% receiving placebo (p=0.01). Conclusions: Patients with bronchiectasis respond to drugs in different ways indicating that single endpoints do not measure the totality of treatment response. The use of a composite endpoint increases the precision of measuring treatment benefit in bronchiectasis clinical trials.
