Self-questioning in the literature classroom: effects on students’ interpretation and appreciation of short stories

In this study we examined the effects of self-questioning on students’ interpretation and appreciation of complex short stories. Two experiments were carried out, in which tenth grade students from different secondary schools participated. In Experiment 1 self-questioning instruction was compared to instructor-made questions about stories. In Experiment 2 two forms of self-questioning instruction were compared: an unguided and a guided form. Literature discussions in peer groups formed a substantial part of all conditions. Results showed that (unguided) self-questioning had a positive effect on students’ appreciation of literary stories, compared to instructor-prepared questions and to guided self-questioning. The results for quality of interpretation were more diffuse. In Experiment 1 effects on students’ story interpretation could not be established. In Experiment 2 a main effect on story interpretation was found for both the guided and unguided form of self-questioning instruction. In addition, students’ reading experience appeared to be important for the effectiveness of the unguided self-questioning condition: avid readers tended to benefit more from this condition than infrequent readers. We conclude that an open literature approach, based on ‘authentic’ student-generated questions in response to short stories, can be beneficial for students’ story interpretation and appreciation.
Seasonal streamflow forecasting by conditioning climatology with precipitation indices

Many fields, such as drought-risk assessment or reservoir management, can benefit from long-range stream- flow forecasts. Climatology has long been used in long- range streamflow forecasting. Conditioning methods have been proposed to select or weight relevant historical time series from climatology. They are often based on general circulation model (GCM) outputs that are specific to the fore- cast date due to the initialisation of GCMs on current conditions. This study investigates the impact of conditioning methods on the performance of seasonal streamflow forecasts. Four conditioning statistics based on seasonal forecasts of cumulative precipitation and the standardised precipitation index were used to select relevant traces within historical streamflows and precipitation respectively. This resulted in eight conditioned streamflow forecast scenarios. These scenarios were compared to the climatology of historical stream- flows, the ensemble streamflow prediction approach and the streamflow forecasts obtained from ECMWF System 4 precipitation forecasts. The impact of conditioning was assessed in terms of forecast sharpness (spread), reliability, overall performance and low-flow event detection. Results showed that conditioning past observations on seasonal precipitation indices generally improves forecast sharpness, but may reduce reliability, with respect to climatology. Conversely, conditioned ensembles were more reliable but less sharp than streamflow forecasts derived from System 4 precipitation. Forecast attributes from conditioned and unconditioned ensembles are illustrated for a case of drought-risk forecasting: the 2003 drought in France. In the case of low-flow forecasting, conditioning results in ensembles that can better assess weekly deficit volumes and durations over a wider range of lead times.
CRYSTALLOGRAPHIC CONTROLS ON TRACE-ELEMENT INCORPORATION IN AURIFEROUS PYRITE FROM THE PASCUA EPITHERMAL HIGH-SULFIDATION DEPOSIT, CHILE–ARGENTINA

The distribution of gold and other trace elements in the ore-stage pyrite from the high-sulfi dation Au–Ag–Cu Pascua deposit in the El Indio belt in north-central Chile was studied using electron-microprobe and secondary-ion mass spectrometry (SIMS) imaging and analysis. The images show that concentrations of Au and Cu are concentrically zoned, and those of Ag, As, Se and Te are zoned both concentrically and sectorally. The principal trace-element associations are As–Ag, Au–Cu and Se–Te. We propose that the fi rst two associations, As–Ag and Au–Cu, refl ect coupled substitutions for Fe, whereas Te and Se replace S by direct-ion exchange. The near-identical patterns of sector zoning of Ag and As suggest that silver enters the structure of pyrite via a coupled substitution with As, in which one atom of Ag and one of As substitute for two Fe atoms, yielding (Ag + 0.5As 3+ 0.5)S2. Gold and copper were excluded during an interval in which growth conditions promoted the development of | hk0 | sectors at the expense of | 111 | sectors; their enrichment patterns show only slight evidence of sectoral preferences. With the analytical methods employed, we could not distinguish unequivocally between incorporation of gold as minute inclusions of the native metal or a coupled substitution of gold as an Au 3+ ion and copper as a Cu + ion for two Fe 2+ ions, yielding (Au 3+ 0.5Cu + 0.5)S2. However, we favor the latter interpretation. Incorporation of gold as Au 3+ is also consistent with evidence of unusually oxidizing conditions during the formation of the Pascua deposit. The zonation of invisible gold and associated trace elements in the ore-stage pyrite at Pascua is the fi rst documented example of crystallographic structural control of the surface on the incorporation of multiple trace elements in pyrite. Moreover, the nature of this zonation provides clear evidence that incorporation of gold in pyrite does not necessarily involve coupled substitution with arsenic, as proposed for many other deposits. Not only can arsenic behave as a metal in the structure of pyrite, but its sectoral pattern of incorporation is a potentially sensitive indicator of redox conditions during mineralization.
EFFECT OF TITANIA COLLOID SOLUTION CONCENTRATION ON HYDROPHOBICITY OF WELL-ALIGNED TIO2 NANORODS SYNTHESIZED VIA HYDROTHERMAL METHOD

Nanorod TiO2 Hydrothermal method WC-12Co Hydrophobicity Among one dimensional nanomaterials, TiO2 nanorods have found important applications in various industries due to optical, photocatalyst and self-cleaning properties. In this research, at first TiO2 nanorods were synthesized on a glass substrate by hydrothermal method. Then a thin film of TiO2 particles was dip coated (as seed layer) on the substrate. After that, hydrothermal synthesis of TiO2 nanorods with 0.05 and 0.1 mol concentrations was carried out on the seed layer. Morphology and microstructure of the seed layer and nanorods were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD) and atomic force microscopy (AFM). Hydrophobicity of nanorods was studied by contact angle instrument. Results revealed that nanorods synthesized on the glass substrate without seed layer are not aligned at all and have the average diameter of 120 nm, whereas nanorods synthesized on the seed layer are well-aligned with 30nm average diameter. The result obtained from contact angle instrument showed that nanorods synthesized with 0.05mol concentration have larger contact angle (157o), compared to those synthesized with 0.1mol concentration which have 115o contact angle.
EFFECT OF SEAWATER MAIN COMPONENTS ON FROTHABILITY IN THE FLOTATION OF Cu-Mo SULFIDE ORE

The main problem in the flotation of Cu-Mo sulfide ores in seawater is poor floatability of molybdenite at pH>9.5. Froth stability plays a very important role in determining concentrate grade and recovery in flotation operations and in this paper both floatability and frothability have been tested. The frothability have been studied by measuring froth equilibrium layer thickness in a modified laboratory flotation cell. Two chemical aspects of seawater need to be considered: the content of NaCl (around 87% of salinity), and the concentration of secondary ions (around 13%) (sulfate, magnesium, calcium, bicarbonate ions, etc.). Seawater, NaCl solutions, and seawater's ions were found to depress frothability. The effect of pH on frothability over the pH range from 9.5 to 11, which is very strong in freshwater, becomes negligible in seawater and the tested electrolyte solutions. The analysis of the relationship between the mechanisms of molybdenite depression and the loss of frothability in seawater implies that the effects of the studied ions on molybdenite floatability and on pulp frothability are different. While depression of molybdenite floatability could be tracked down to magnesium hydroxide precipitation as a main culprit, the depression of frothability is a much more complicated issue.
The pertinence of training and development and their componentsin non-training standards from the viewpoints of the managers andexperts of the manufacturing-service organizations in Iran

The purpose of this study is to investigate the pertinence of training and its components in non-training standards from the viewpoints of the managers and experts of the manufacturing-service organizations in Iran. It is a functional research in purpose. The research method is a mixed one consisting of qualitative and quantitative methods. For data collection and quantitative analysis, the questionnaire was used through a survey method and the categorization is also applied qualitatively. The statistical population includes all the managers and experts of human resources training and development in manufacturing-service organizations in Iran and 64 of them were selected as the research sample through simple sampling. In this study three training standards and 11 non-training standards were weighted and analyzed. In the content analysis with a categorization approach, 9 components were identified and weighted. The data analysis is presented in two general sections: 1) the training experts’ viewpoints toward evaluating and prioritizing training components and 2) the perspectives of the managers and the experts toward the pertinence of training components in non-training standards. In the first section, competence was the most important component while the training strategy was considered the least important one. The most prominent point presented in the second section is that “the pertinence of training in the non-training standards is generally inappropriate”.
Characterization of Laser Scanners for Detecting Cracks for Post-Earthquake Damage Inspection

Objective, accurate, and fast assessment of damage to buildings after an earthquake is crucial for timely remediation of material losses and safety of occupants of buildings. Laser scanners are promising sensors for collecting geometrical data regarding the damaged states of buildings, as they are able to provide high coverage and accuracy at long ranges. Yet, we have limited knowledge on the performance of laser scanners for detecting earthquake damage, and requirements of such data collection. This paper focuses on characterizing the performance of laser scanners for detecting thin cracks for damage assessment of reinforced concrete frames. We identified a series of crack parameters based on the state-of-the-art damage assessment codes and standards. Similarly, we identified parameters, which affect the performance of laser scanners for detecting cracks, based on prior research in this area. We studied the width, depth, and orientation of cracks; sampling interval of the scanner, and the range of the laser beam from the surface. Effects of these parameters on the detection of the minimum crack size were determined in an experimental setting. An automated algorithm was used to analyze the data. The results show that it is possible to detect as small as ~1mm cracks.
Cross-Media Production in Spain's Public Broadcaster RTVE: Innovation, Promotion, and Audience Loyalty Strategies

Multiplatform content broadcasts are one way of securing the position of public-service broadcasting in a competitive and changing market. This research focuses on the crossmedia fiction series Aguila Roja (Red Eagle) and Isabel, produced by Globomedia and Diagonal TV for Radio Television Espanola (RTVE), the Spanish radio and television corporation. RTVE is a public-service broadcaster that has recently undergone a significant reconversion as a consequence of the recession and a new funding system based exclusively on financial contributions from the state, with a ban on paid advertising, which had been permitted in the past. We examine the way this organization creates productions for multiple platforms and the innovation strategies that support these processes. Using a comparative case study approach based on the actor-network theory, we found a strong 360-degree cross-media production logic in RTVE’s fiction series. However, a detailed analysis reveals difficulties and contradictions regarding the efficacious use of each of the technological platforms available as well as limitations on the actions undertaken in the social media.

LOCOMOTION IN FOSSIL CARNIVORA: AN APPLICATION OF EIGENSURFACE ANALYSIS FOR MORPHOMETRIC COMPARISON OF 3D SURFACES

We present a new geometric morphometric method called ‘eigensurface analysis’ for the quantitative analysis of three-dimensional (3D) surfaces. Eigensurface can be viewed as an extension of outline- and landmark-based geometric methods to deal with complete 3D surfaces of objects. We applied eigensurface analysis to the problem of functional inference based on the mammalian calcaneum bone, which is commonly preserved in isolation. Functional interpretations in vertebrate paleontology can be confidently drawn from relatively complete skeletons based on limb proportions and suites of locomotor characters. Interpretations drawn from isolated bones are often less certain, in part because the functionally important features on which the interpretations are based are the curvatures and angles of joint surfaces, which are difficult to quantify using standard linear measurements or 2D geometric morphometric approaches. Eigensurface analysis allows the entire surface (or surface region) of a specimen to be analyzed by interpolating an evenly spaced grid of semi-landmark points from a standard 3D point-cloud, such as those generated by laser scanners. The same mathematically homologous point grid is fit into each object in a study, which allows the geometry of the grids to be analyzed in the same way one would standard landmark or outline point data. Eigensurface analysis also supports direct shape modelling within the ordination spaces formed to represent shape similarities, thus forming a critical bridge between these mathematical spaces and the qualitative assessment-comparisons of the shapes they represent. We used the eigensurface method to characterize the calcaneum shape of modern carnivorans in respect to stance, number of digits, and locomotor style. We then quantitatively matched the calcanea of four extinct species to those categories to infer stance, digit number, and locomotor style. Four taxa—Ictitherium, an extinct hyaena, Enhydriodon, an extinct otter, Paramachairodus, an extinct sabre-toothed cat, and Cynelos, an extinct amphicyonid—whose anatomy and locomotion are known from independent evidence, were used to assess the effectiveness of eigensurface analysis of individual calcanea. Results allowed us to infer the number of toes, the stance, and the locomotor mode of all four of the taxa correctly. Cynelos was incorrectly inferred to have been digitigrade, and Enhydriodon was incorrectly inferred to have been terrestrial.
Stearn , under a multivariate framework Selección del genotipo de Pouteria sapota ( Jacq . )

The Pouteria sapota, also popularly known as sapote or mamey sapote, is a fruit tree of sapotaceae family originally from the tropical region of Central America with a great importance due to the almost complete utilization of the tree (fruit, seeds and wood) by industries. Thus, the study of its features becomes indispensable for selecting the most promising genotypes to increase the profitability of its production. In this study, it was used a dataset of 63 sapote trees placed in the botanical garden of Centro Agronómico Tropical de Investigación y Enseñanza (CATIE), located in Turrialba, Costa Rica. 17 quantitative characteristics were measured from trees, in order to evaluate the yield potential through the application of two multivariate statistical techniques: factor analysis (FA) and cluster analysis (CA). Firstly, the FA was performed and the 17 initial characteristics were reduced to four common factors that might describe particular characteristics like “fruit”, “seed”, “wood” and “leaf”. Thereafter, a CA was performed, with scores of FA, which allows the formation of five groups of trees with different traits. This methodology revealed the most promising trees in the economic point of view for every industry that uses the tree as raw material.

Adolescent rights comprehension: The influence of age, intelligence, and interrogative suggestibility

Research demonstrates that many adolescents show poor comprehension of their legal arrest rights. This finding is concerning given recent trends towards the increased availability of severe punishments for youths convicted of serious crimes. This study investigates the relationship between age, intellectual ability, interrogative suggestibility and arrest rights comprehension in a Canadian sample of 94 adolescents 12 to 19 years of age. Participants completed the Wechsler Abbreviated Scale of Intelligence, Grisso's Instruments for Assessing Understanding and Appreciation of Mirundu Rights, and the Gudjonsson Suggestibility Scales. Results showed that age and IQ significantly and independently predicted rights comprehension. Younger adolescents did not understand their rights as well as older adolescents, and youths with lower intellectual ability levels also demonstrated more impaired comprehension of their rights. Interrogative suggestibility was inversely related to rights comprehension, and this relationship was mediated by IQ, but not moderated by age. The implications of these findings are discussed.
Spin-wave logic devices based on isotropic forward volume magnetostatic waves

We propose the utilization of isotropic forward volume magnetostatic spin waves in modern wave-based logic devices and suggest a concrete design for a spin-wave majority gate operating with these waves. We demonstrate by numerical simulations that the proposed out-of-plane magnetized majority gate overcomes the limitations of anisotropic in-plane magnetized majority gates due to the high spin-wave transmission through the gate, which enables a reduced energy consumption of these devices. Moreover, the functionality of the out-of-plane majority gate is increased due to the lack of parasitic generation of short-wavelength exchange spin waves.
