CORRECTIVE FEEDBACK , REVISION , AND LEARNING

Corrective feedback, the necessity of providing it, and how it should be provided has been one of the hot topics in the area of ELT. Amid continuing controversies over whether providing feedback helps L2 learners improve their writing accuracy, many research studies have been undertaken to compare the relative effectiveness of different types of feedback. However, the difference between two types of indirect corrective feedback, namely indication and indication plus location, have not been properly examined yet. Motivated to narrow this gap, this study is designed to compare two groups of Iranian learners, each revising their papers based on one of the aforementioned options. For data analysis, a series of independent samples t tests were employed. The results revealed that the difference between the two groups in their reduction of errors from the original draft to the revision of each task followed a growing trend and became significant. Nonetheless, the difference in accuracy of new pieces of writing fell short of significance. Finally, it was found that error reduction in revision stage cannot be considered as learning. The results of the study, discussed in relation to that of others, implicate that the purpose for which feedback is provided is essential in determining the type of feedback; more explicit feedback is better for revising purposes while more implicit feedback is good for learning purposes.
Estimation of genetic parameters of Thoroughbred racing performance in the Czech Republic

The aim of this study was to estimate the breeding value of English Thoroughbreds in the Czech Republic using racing results from a 22-year period (1980-2001). The data include the performance of two and three-year-old horses which raced in flat races at hippodromes in the Czech Republic. The racing results (30 203) were available corresponding to 6 333 horses descending from 762 sires and 2 836 dams. Different criteria were applied in order to analyse the performance: Log of earnings per race, a normalized ranking value, distance of the race when placed, earnings and number of starts for 2, 3, 2+3 year-old horses. After preliminary studies, a year effect or a sex by year effect was finally retained. Variance component estimation using VCE software gave the following values for heritability (±standard errors): 0.14 ± 0.01 and 0.16 ± 0.01 for the Log of earnings per race and the ranking value. Repeatability was 0.31 and 0.35, respectively. The maternal environment component was evaluated as 0.02 ± 0.004 for the Log of earnings per race and 0.03 ± 0.004 for the ranking value. We found that the Log of earnings per race and the ranking value were two appropriate criteria when taking into account racing performance in selection for Thoroughbreds in the Czech Republic. The genetic correlation of the two criteria was 0.98 ± 0.003. The heritability for the distance when placed was 0.18 ± 0.01. The genetic correlation of the Log of earnings per race and distance was medium, 0.38 ± 0.05 and of the same order, 0.39 ± 0.05 for ranking value and distance. In the case where we used the Log of annual earnings and the number of starts, the heritabilities were for the Log of earnings: 0.15 ± 0.03 for two-year-olds, 0.34 ± 0.03 for three-year-olds and 0.32 ± 0.03 for two and three-year-old careers together and respectively, 0.12 ± 0.03, 0.21 ± 0.03 and 0.20 ± 0.02 for number of starts. The genetic correlations between the earnings and the number of starts were respectively: 0.26 ± 0.14, 0.33 ± 0.06 and 0.19 ± 0.07. The genetic correlation between the number of starts for two and three year-olds which was restricted to horses earning money for two consecutive years, was average: 0.35 ± 0.05 and between earnings for the same ages was high 0.80 ± 0.04.
KELVIN–HELMHOLTZ INSTABILITY OF THE CME RECONNECTION OUTFLOW LAYER IN THE LOW CORONA

New capabilities for studying the Sun allow us to image for the first time the magnetic Kelvin–Helmholtz (KH) instability developing at the surface of a fast coronal mass ejecta (CME) less than 150 Mm above the solar surface. We conduct a detailed observational investigation of this phenomenon, observed off the east solar limb on 2010 November 3, in the EUV with SDO/AIA. In conjunction with STEREO-B/EUVI, we derive the CME source surface position. We ascertain the timing and early evolution of the CME outflow leading to the instability onset. We perform image and spectral analysis, exploring the CME plasma structuring and its parabolic flow pattern. As we evaluate and validate the consistency of the observations with theoretical considerations and predictions, we take the view that the ejecta layer corresponds to a reconnection outflow layer surrounding the erupting flux rope, accounting for the timing, high temperature (∼11.6 MK), and high flow shear (∼680 km s−1) on the unstable CME northern flank and for the observed asymmetry between the CME flanks. From the irregular evolution of the CME flow pattern, we infer a shear gradient consistent with expected spatial flow variations across the KH-unstable flank. The KH phenomenon observed is tied to the first stage of a linked flare–CME event.
Non-methane hydrocarbon variability in Athens during wintertime: the role of traffic and heating

Abstract. Non-methane hydrocarbons (NMHCs) play an important role in atmospheric chemistry, contributing to ozone and secondary organic aerosol formation. They can also serve as tracers for various emission sources such as traffic, solvents, heating and vegetation. The current work presents, for the first time to our knowledge, time-resolved data of NMHCs, from two to six carbon atoms, for a period of 5 months (mid-October 2015 to mid-February 2016) in the “greater Athens area” (GAA), Greece. The measured NMHC levels are among the highest reported in the literature for the Mediterranean area during winter months, and the majority of the compounds demonstrate a remarkable day-to-day variability. Their levels increase by up to factor of 4 from autumn (October–November) to winter (December–February). Microscale meteorological conditions, especially wind speed in combination with the planetary boundary layer (PBL) height, seem to contribute significantly to the variability of NMHC levels, with an increase of up to a factor of 10 under low wind speed (<3 m s−1) conditions; this reflects the impact of local sources rather than long-range transport. All NMHCs demonstrated a pronounced bimodal, diurnal pattern with a morning peak followed by a second peak before midnight. The amplitude of both peaks gradually increased towards winter, in comparison to autumn, by a factor of 3 to 6 and closely followed that of carbon monoxide (CO), which indicates a contribution from sources other than traffic, e.g., domestic heating (fuel or wood burning). By comparing the NMHC diurnal variability with that of black carbon (BC), its fractions associated with wood burning (BCwb) and fossil fuel combustion (BCff), and with source profiles we conclude that the morning peak is attributed to traffic while the night peak is mainly attributed to heating. With respect to the night peak, the selected tracers and source profiles clearly indicate a contribution from both traffic and domestic heating (fossil fuel and wood burning). NMHCs slopes versus BCwb are similar when compared with those versus BCff (slight difference for ethylene), which indicates that NMHCs are most likely equally produced by wood and oil fossil fuel burning.
Calculation of cross selection for elastic scattering of electrons by a magnesium atom at intermediate energies

Elastic electron-atom collision data from experimental and theoretical studies is useful in the interpretation of spectra obtained in X-ray photoelectron spectroscopy and Auger electron spectroscopy as well as in the Monte Carlo simulation of conduction electrons in solids. In principle the behaviour of an electron-atom collision system is predicted by solving the Schrödinger equation. However this task is far from simple in that the equation can only be solved exactly for a two-body collision problem and consequently approximation methods are necessary for electron-atom scattering. In this study the Optical Model Potential method was used to calculate cross sections for elastic scattering of electrons by a magnesium atom at intermediate energies. Computer program PSCATT was developed to solve the Schrödinger equation numerically. Through use of a complex optical potential which accounts for possibility of inelastic processes at intermediate energies, the results obtained were found to be in fairly good agreement with recent measured results. The present results were also found to be comparable to, and in some cases better than, theoretical results obtained using sophisticated multi-channel methods. The computer program used in this study is much less demanding on computer power than the computer codes associated with multi-channel methods which has implications in terms of reducing research costs.
Comparison of the Levels of LH and FSH, TSH, Prolactin, Progesterone and Estradiol Hormones between Iranian Infertile Women with Polycystic Ovary Syndrome and Healthy Women

Polycystic ovary syndrome (PCOS) with the prevalence of 5 to 7% among Iranian women is a leading cause of infertility and endocrine disorder. Metabolic disorders such as increased levels of LH and FSH hormones in these patients was common and influences health of women with PCOS in long-term. Treatment of female infertility and other complications in many cases need to regulate hormones and receive exogenous hormone, and then the effect of female hormones on the disease is very important. In this study, levels of Luteinizing hormone (LH) and Folliclestimulating hormone (FSH) and other female hormones among Iranian women with PCOS and infertility and healthy people were measured in this regard and values were compared. The result of this study showed that LH and progesterone hormone levels were significantly different in this syndrome than healthy women.
EFFECT OF IMMUNOGLOBULIN Y PURIFIED FROM IMMUNIZED HEN EGGS ON THE GROWTH OF STAPHYLOCOCCUS AUREUS

A novel purification method of egg yolk immunoglobulin (IgY) based on precipitation using agarPEG was developed. This me thod was compared with chloroform extraction and polyethylene glycol (PEG) precipitation methods. The results showed the protein contents were high with chloroform method followed by agarPEG then PEG method. The purity of resultant I gY was homogeneous with agar� PEG method followed by PEG method then chloroform extraction method. The IgY purified by agar -PEG method, obtained from hens immunized by formalintreated S. aureus , showed a significant reduction in bacterial growth and the growth inhibition was dependent on specificIgY concentration.
Milling Characteristics and Nutritional Quality of Paddy Rice Processed Using Biomass Powered Stove

Milling and nutritional quality of rice processed using wood and rice-husk briquette powered biomass stove was investigated. There was significant difference (p≤0.05) in milling attributes of the processed rice among volumetric air flow rates. There was no significant difference (p≥0.05) in the milling attributes of the processed rice between the treatments. The L-values ranged from 60.20 to 62.40 with the least values at 0.18 m3/s and 0.20 m3/s and the highest value at 0.25 m3/s. The percentage head rice (HR) ranged from 98.50 to 98.83% which were fairly the same. The lowest and highest values of (HR) were obtained at 0.25 m3/s and natural air flow. Milling recovery (MR) ranged from 68.21 to 68.60% with the highest values at 0.25 m3/s and the least value at natural air flow. Similar trends were observed for milling attributes with exception of chalkiness that remained constant for all treatments. The values for other quality parameters of the milled rice showed that fire wood and briquette recorded fairly similar values, although, briquette recorded higher values in some cases with the exception of chalkiness that showed exactly the same trend at different treatments. The carbohydrate content of the rice processed using briquette was higher than those processed using fire wood and most of the other quality indices such as protein, ash which is an indication of presence of mineral elements were higher for briquettes compared with fire wood. The results revealed that powering the stove was advantageous since the quality indices of the rice were enhanced.
Mangrove Area Assessment in India: Implications of Loss of Mangroves

Mangroves are extremely important bio-resources which are crucial to coastal environment. Mangroves are declining rapidly as they are getting degraded for agriculture, aquaculture, tourism, urban development and over-exploitation. India lost 40% of its mangrove area during the last century. Hence, it is highly necessary to assess the status and trends of mangroves in India. We have assessed the trends of mangrove area in India during 1987-2013 and found that the mean annual change during the period is 24.25 ± 82.57 km2. Most of the states are experiencing an increase in area except Andhra Pradesh (-5.95 ± 15.70 km2) and Andaman and Nicobar (-3.41 ± 52.32 km2). The present review is focused on assessing the status and trends of mangrove area in India including the causes of loss and its restoration and traditional conservation. Implications of loss of mangroves have been discussed with respect to exposure to cyclones, hurricanes and sea water intrusion, tsunami and climate change. Effective governance structures, better planning for rehabilitation of degraded mangroves, education and awareness building in local communities are needed to conserve, protect and restore the valuable mangrove wetland ecosystems. Further, mitigation and adaptation to climate change aspects are considered.
Factors Influencing Saudi Mothers Success in Exclusive Breastfeeding for the First Six Months of Infant Life: A Cross-Sectional Observational Study

Introduction: Although breastfeeding has been shown to have dual benefits for both infants and their mothers, the global rate of breastfeeding has been declining, especially in Middle Eastern countries. This decline necessitates an urgent exploration of the determinants of breastfeeding practices. Objectives: This study was conducted to evaluate the breastfeeding practices of Saudi mothers, compare them to the guidelines and recommendations of the World Health Organization and to examine the possible determinants of success in exclusive breastfeeding for the first six months of life. Methods: A quantitative observational cross-sectional study was conducted in 322 selected mothers of children between 6 months and 24 months of age who attended the well-baby clinic at King Saud University Medical City, Riyadh (2015). Results: Although 94.4% of the 322 Saudi mothers were successful in initiating breastfeeding on the first day of delivery, only 13.7% of all infants were exclusively breastfed at the age of 6 months. Factors predicting exclusive breastfeeding for the first six months of life in the study sample were previous experience with exclusive breastfeeding and the intention to exclusively breastfeed. In addition, the frequency of breastfeeding on demand at day and night was found to be significant. Sources of breastfeeding support are of great concern. Conclusion: The majority of Saudi mothers have suboptimal breastfeeding practices. A cohort study enrolling a larger number of exclusively breastfed infants is needed to gain a full understanding, as are actions to bridge the gap between current breastfeeding practices and the World Health Organization recommendations.
The Structure of Atomic and Molecular Clusters, Optimised using Classical Potentials

The problem of the determination of the minimum energy configuration of an arrangement of point particles under the interaction of their interatomic forces is discussed. The interatomic forces are described by classical many body potentials. Different optimisation methods are considered, multi level single link, topographical differential evolution and a genetic algorithm but it is shown that genetic algorithms combined with an efficient local optimisation method is especially quick and reliable for this task. In addition to comparing some different optimisation methods, the structures of clusters of atoms described by interatomic potential functions containing up to a few hundred atoms are calculated including some with some special symmetries. A number of applications are given including covalent carbon and silicon clusters, close-packed structures such as argon and silver and the two-component carbon-hydrogen system.
THE ROLE OF A SPECIFICATION IN THE DESIGN PROCESS: A CASE STUDY

The role of design specification in the design process is recognised as significant because it helps design engineers to proceed from the abstract to the concrete solution so as to fulfill the aim of the product. Thus to obtain insight about the role of design specifications during the design process, a case study was carried out in a consultancy company. The interview was chosen as a data collection method and the transcription of the interviews was indexed against a predefined coding scheme. The study found the specification has multiple roles in the product development environment and the company, product and project was very much influencing the development of a specification.
PAN nanofibers reinforced with MMT/GO hybrid nanofillers

Single component nanofiller has shown some limitations in its performance, which can be overcome by hybrid nanofillers with two different components. In this work, montmorillonite (MMT)/graphene oxide (GO) hybrid nanofillers were formed by self-assembly and then incorporated into the polyacrylonitrile (PAN) nanofibers by electrospinning process. X-ray diffraction (XRD), atomic force microscopy (AFM), and transmission electron microscopy (TEM) were utilized to analyze the structures of MMT/GO hybrid nanofillers. And the effects of MMT/GO hybrid nanofillers on the morphology, thermal stability, and mechanical properties of PAN/MMT/GO composite nanofibrous membrane were examined by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and tensile test machine, respectively. The incorporation of MMT/GO hybrid nanofillers into PAN nanofibers showed a noticeable increase up to 30°C for the onset decomposition temperature and 1.32 times larger tensile strength than the pure PAN, indicating that the hybrid nanofiller is a promising candidate in improving thermal and mechanical properties of polymers.
Exploring project portfolio management decisions : the role of intuition and entrepreneurship in project portfolio outcomes

The PPM literature highlights that project portfolio management (PPM) is a decision-making process [1] which involves both minimising and diversifying risk and making trade-offs [2]. For an enterprise, PPM is a critical topic since it integrates a number of key areas: project selection and prioritisation, resource allocation across projects, and implementation of the business strategy [3, 4]. A strategic decision is one which is important in terms of the actions taken, the resources committed, or the precedents set i.e. those decisions that can critically affect organisational health and survival [5]. In this context PPM decisions are strategic. Cooper et al. [6, 7, 8] note that new products are the leading edge of a firm’s strategy. The product choices made today determine how the firm’s product offering and market position will be in the future. This is why the PPM literature has focused on innovation or New Product Development projects. The literature regarding PPM decision making is based around the rational approach [9] even though the conditions under which executives operate may preclude this approach. Intuition has really been overlooked or discarded in the PPM decision-making process literature. Research suggests that executives do make significant use of intuition [10]. In fact intuition (business instinct) is a distinguishing characteristic of the successful performers [11]. Entrepreneurial intuition is suggested to be associated (non-exhaustively) with creativity and innovation [12]. The resulting topologies of PPM decision making have, therefore, tended to be incomplete or overlapping. None have captured the full range of content associated with the phenomenon of entrepreneurial intuition and its role in the PPM decision making process. This paper reviews the PPM literature with special emphasis on the decision-making process and the role of entrepreneurship and intuition in project portfolio outcomes and concludes with suggestions for further research. It is hoped that a deeper understanding of the PPM decision process will result in improvement in management practice and instigate changes in management thinking within the PPM field.
Quality Control of Honey Using New Generation Infrared Spectrometers

The objective of this study was to develop a rapid infrared technique to determine 10 key quality parameters (sucrose, glucose, fructose, reducing sugar, 5-HMF, °Brix, moisture content, water activity, pH and free acidity) in honey by using new generation portable and handheld devices. The composition of honey samples (n=59) collected from different parts of Turkey was analyzed by using established reference methods, giving wide range of concentrations for each parameter. The levels of sucrose and 5-HMF in some samples were above the established regulatory limits (Codex Alimentarius and European Union standards), indicating possible adulteration or process and storage abuse. Spectra were collected by using portable Fourier-Transformed infrared (FTIR) and handheld NIR (Near Infrared) spectrometers. Partial least squares regression (PLSR) approach was used to correlate the spectral features with compositional reference values, giving strong linear correlation coefficients and standard errors of prediction. Although both systems performed similarly, portable FTIR system was superior in predictions of sucrose, 5-HMF and free acidity while portable NIR system performed noticeably better for °Brix and moisture content. The data indicates that all of the 10 parameters can be measured within the minutes using both systems, providing reliable screening capabilities, flexibility and the potential for in-field applications.
