Evaluation of Rotatable Downlets for Wing Weight Reduction

The use of winglets is known to benefit lift-to-drag ratios and induced drag. Coupling this benefit with the use of a rotatable component within the winglets allows the conversion of a passive aerodynamic device into an active manoeuver load alleviation device. A rotatable downlet allows the reduction of wing root bending moment by up to 8%. This reduction in bending moment, when coupled with aeroelastic tailoring, produces a 2.1% reduction in wing structural weight in addition to the increased lift to drag ratios.
School principals and leadership identity: A thematic exploration of the literature

ABSTRACT Background: In the last decade, much research attention has been paid to notions of leadership and the professional identity of school. It is widely agreed that school principals play a very important role in school improvement; international reports point to ‘school leadership’ as a key factor in education quality, and recent studies suggest that the leadership identity of principals is critical for achieving effective leadership in schools worldwide. Purpose: The purpose of this study was to conduct a thematic exploration of the literature relating to school principals and leadership identity. Design and methods: A scoping review was carried out. Two major databases were searched for papers published on this topic in the last decade. Once we had established an overview of research on this subject, we conducted a thematic analysis to identify the topical focus of research. Results: We found that the literature reflected an increasing and intensified interest in the topic of school leadership as the decade progressed. Furthermore, a range of emerging subtopics was identified. These included the relationship between school culture and professional identity in school principals; the influence of ethical and personal factors on the professional development of principals; the dilemmas of balancing education policies and personal experiences; and the relationships between gender identity, racial identity, professional experience/career, training and leadership identity. Conclusions: Several key issues emerged from the studies included in this review, such as the importance of external and internal influences in the construction of the professional identity of school principals. Some of the research suggested that school leaders felt the need to develop a new professional identity. Overall, the study indicates that school leadership and its relationship with school improvement should remain an important focus for educational research investigation.
The Effects of Problem-Oriented Policing on Crime and Disorder: A Systematic Review

Background: Problem-oriented policing (POP) was first introduced by Herman Goldstein who argued that police were not being effective in preventing and controlling crime because they had become too focused on the “means” of policing and had neglected the “goals” of preventing and controlling crime. Goldstein believed that the unit of analysis in policing must become the “problem” rather than calls or crime incidents. POP has had tremendous impact on American policing, and is now one of the most widely implemented policing strategies in the U.S. The goal of this study was to synthesize the extant problem-oriented policing evaluation literature and assess the effects of problem-oriented policing on crime and disorder using a Campbell Collaboration systematic review methodology 2 .
Which contextual and sociocultural information predict irony perception?

ABSTRACT The present study in French sought to investigate which factors predict irony perception most efficiently. An experiment was developed following three steps. The first two steps focused on the creation of stimuli to be evaluated in the third step. In this last step, participants, whose sociocultural characteristics (gender, age, and level of education) were taken into account as factors, evaluated utterances according to their level of irony and the presence of contextual factors (i.e., allusion to a failed expectancy, negative tension, and presence of a victim). The absence or presence of a lexical marker in the utterances was also a controlled factor. The main results revealed contextual factors as the strongest predictors of irony perception, but also pointed out the not inconsiderable role played by the sociocultural factors (gender and level of education) of the participants.
Wave Transmission on Submerged Rubble Mound Breakwater Using L-Blocks

Laboratory tests on a permeable submerged rubble mound breakwater (SRMB) constructed using L-Blocks armour unit with 40 tests for wave transmission were analyzed and the available empirical equations for wave transmission coefficient (K t ) were evaluated. The ranges of variation were 0.23< d s /d<0.38, 0.001< H i /(gT 2 ) <0.022, 0.011< H i /L<0.139, and 0.769<B/d<0.625 where B is the top width of the breakwater and L is the incident wave length. The design parameters varied systemically to investigate the impact of incident wave height (H i ), wave period (T), water depth (d), and submergence depth (d s ) on the values of K t . The tests were performed in a wave flume 23 m long and 2 m wide. The armor units were L-Block artificial armour unit with the relative density of 2.4. The results showed that for various relative submergence depth, d s /d, (i) little correlation was found when K t correlate with B/d. (ii) K t correlates well with wave steepness H i /L and with H i /(gT 2 ). Four commonly used
The contribution of cultural intelligence to the interaction involvement and performance of call center agents in cross-cultural communication

This paper aims to investigate the contribution of cultural intelligence (CQ) to the interaction involvement and job performance of call center agents in the Philippines. ,Data were collected from 213 call center agents from five business process outsourcing firms in the Philippines. Partial least squares structural equation modeling was used for data analysis. ,CQ was found to be positively associated with the quality of interaction involvement and job performance of the call center agents. Moreover, the positive contribution of CQ to interaction involvement and job performance was significantly greater for those that had less call center work experience than those that had more work experience. ,This study indicates that CQ not only matters in face-to-face communication but also is beneficial for non-personal communication, as with telephone conversation for example. In addition, this study showed new evidence –possessing high CQ tends to be more beneficial for agents that have less work experience.
Effects of a digital educational intervention on collaborative learning in nursing education: A quasi-experimental study

Collaborative digital learning is becoming increasingly popular in higher education. However, the use of collaborative digital learning does risk placing too big a responsibility on the learner and reducing face-to-face interaction with the educator. The aim of this quasi-experimental study was to evaluate the effects of a digital educational intervention on collaborative learning in nursing education. The intervention group (n = 87) studied using a collaborative digital learning environment and the control group (n = 38) studied in the traditional classroom setting. There were no significant differences between the groups in terms of student satisfaction. However, the students' satisfaction of studying decreased in the intervention group after completion of the course. In the intervention group students had higher satisfaction in the area of promoting collaborative group work and received statistically significant higher grades in the final course evaluation. This study emphasizes that collaborative digital learning can be an effective approach in nursing education in terms of learning outcomes. It also shows that more study is needed on the role of the teacher in collaborative digital nursing education.
Investigation into the Gender Difference of Attitude and Achievement in Engineering Mathematics

This study was carried out to investigate the students’ attitude towards engineering mathematics. The sample consist of 502 (332 males and 170 females) year one, higher national diploma students, Waziri Umaru Federal Polytechnic, Birnin Kebbi. The study examined the difference in attitudes towards mathematics between male and female students. Pearson correlation, paired samples t-test and independent samples t-test were used to analyze the data using SPSS version 20.0. The results obtained showed a significant difference in attitude towards mathematics between males and females. Female students exhibit more positive attitude than males. No significant difference was observed between males and females in mathematics achievement. The study revealed a weak negative correlation between students’ attitude towards mathematics and students’ achievement.
Young Children’s Use of Gender for Inductive Generalizations about Biological and Behavioral Characteristics: The Influence of Gender Categories and Gender Stereotypes

Using a triad inductive reasoning task, we examined the influence of gender category information, gender stereotypes, and gender salience on young children’s (N = 72; 36 to 69 months of age) generalizations concerning novel biological and behavioral characteristics. Prior to the inductive generalization task, children heard vignettes in which a teacher either engaged in gender stereotyping (Stereotype condition), grouped children according to gender (Salience condition), or grouped children in a gender-neutral manner (Neutral condition). Children generalized on the basis of gender more often in the Stereotype condition than in the Neutral condition, but older children made gender-based inductions at above chance levels in the Neutral condition and for behavioral traits in the Salience condition. Stereotyping influenced gender-based reasoning, but did not appear to be necessary among older preschool children.
Hispanic Millennial Ideology: Surprisingly, No Liberal “Monolith” Among College Students

The goal of this study is to analyze the ideological positions of Hispanic college students in the U.S. Rio Grande Valley (RGV). Building on Feldman and Johnston’s work, where they argue that a unidimensional model of political ideology provides an incomplete basis for study, we employ two dimensions to account for domestic policy preference. The core of the study is a taxonomic analysis of a survey of RGV college students taking government courses, where we find that the political beliefs of Hispanic millennials trend significantly more conservative and, especially, libertarian than expected. Possible implications for the future include a realignment of Hispanics with the Republican Party, a shift in a more libertarian direction within the Democratic Party itself, or an increase in younger Hispanics’ proclivity for independence from the two major parties. Our findings conform to Feldman and Johnston’s argument that the economic and social dimensions of political ideology are separate and distinct, making it essential that researchers analyze both dimensions in order to have an accurate and comprehensive understanding of individuals’ political ideology. In addition, using recent American National Election Studies (ANES) data sets, we compare how our samples are different from the general U.S. population, employing a principal component analysis (PCA).
Surface modification of nettle fibers by grafting to improve oil sorption capacity

In this study, an attempt was made to enhance the oil sorption capacity of nettle fibers by grafting of butyl acrylate. Box–Behnken experimental design was used to study the effect of parameters such as reaction time, reaction temperature and monomer concentration-to-fiber ratio on graft add-on (%) and oil sorption capacity. At 4-h reaction time, 70℃ temperature and 2% monomer concentration-to-fiber ratio, highest graft add-on (%) and oil sorption were attained. Maximum oil sorption capacity of grafted nettle was 36.60 g/g and 25.56 g/g against crude oil and vegetable oil, respectively. Grafted nettle fibers were also subjected to characterization by Fourier-transform infrared spectroscopy, scanning electron microscopy and contact angle tests. Reusability test results showed that grafted nettle exhibited better oil sorption capacity than unmodified nettle even after seven sorption–desorption cycles. It is also observed that the oil sorption capacity of grafted nettle was higher than that of commercial polypropylene material. Based on these results, it is concluded that functionalized nettle prepared by grafting technique can be a potential material for oil spill treatment.

The article is devoted to the analysis of problems of engineering specialists training in Russia. The methodology for the improvement of education quality in higher educational institutions, based on the use of active forms of psychological and pedagogical support in the teaching process, is proposed. The recommendations are developed for the improvement of educational process by teaching staff. The method of psychological and pedagogical support of engineering students training is proposed. Developed methodology is intended for the formation and improvement of psychological support of educational process. Its application contributes to simultaneous formation of cognitive and communicative competences of engineering specialists. An individual approach, with the use of proposed methodology, helps to identify the students' potential, to control the psychological state and to correct it in a timely manner. For the effective application of the proposed methodology, it is necessary to increase the professional level of teachers, in terms of psychological preparation, and also to involve professional psychologists in the work. The qualitative level of training of modern engineers can be enhanced through the active use in teaching the individual forms of education, taking into account the psychological characteristics of the student’s personality.
Diferencias de género en la influencia de la personalidad sobre la procrastinación académica en estudiantes universitarios peruanos

El objetivo del presente estudio fue analizar si existen diferencias entre varones y mujeres en cuanto a la influencia de las dimensiones de personalidad sobre la procrastinacion academica en 986 alumnos (69.8% mujeres; M edad = 20.81 anos) de diferentes carreras profesionales de dos universidades ubicadas en Lima. Para esto, se administro la Escala de Procrastinacion Academica (EPA) y el Big Five Inventory-15P (BFI-15P) y se implemento un analisis de invarianza de un modelo regresion estructural. Los resultados mostraron que la personalidad explica un porcentaje significativo de la variabilidad de las dimensiones de la procrastinacion academica, y que la influencia de las dimensiones responsabilidad y neuroticismo fue mayor en las mujeres. Se discuten las implicancias teoricas y practicas de los hallazgos, asi como la necesidad de fortalecer planes curriculares orientados a potenciar recursos y reducir los aspectos que podrian afectar negativamente la conducta academica del estudiante. Gender differences in the influence of personality on academic procrastination in Peruvian college students Abstract The objective of the present study was to analyze whether there are differences between men and women in terms of the influence of personality dimensions on academic procrastination. Participants were 986 students aged between 16 and 40 years (69.8 % women, Mage = 20.81 years), students of different professional careers from two universities located in Lima. The Academic Procrastination Scale (APS) and the Big Five Inventory-15P (BFI-15P) were the instruments administered. An invariance analysis of a structural regression model that indicates the influence of personality on academic procrastination was implemented. The results show that personality explains a significant percentage of the variability of the dimensions of academic procrastination. However, the influence of two dimensions, consciousness and neuroticism, is greater in women. The theoretical and practical implications of the findings are discussed, as well as the need to strengthen curricular plans aimed at enhancing resources and reducing those aspects that could negatively affect the academic behavior of the student. Key words : academic procrastination, personality, college students, invariance, structural regression.
Computational Aesthetics and Image Enhancements using Deep Neural Networks

Imaging devices have become ubiquitous in modern life, and many of us capture an increasing number of images every day. When we choose to share or store some of these images, our primary selection criterion invariably is to choose the most visually pleasing ones. Yet, quantifying visual pleasantness is a challenge, as image aesthetics not only correlate with low-level image quality, such as contrast and blurriness, but also include mid-level and high-level visual processes, like composition and context. For most users, a considerable amount of manual effort and/or professional knowledge is required to get aesthetically pleasing images. Developing automatic solutions thus benefits a large community. This thesis proposes several computational approaches to help users obtain the desired images. The first technique aims at automatically measuring the aesthetics, which benefits the users in selecting and ranking images. We form the aesthetics prediction problem as a regression task and train a deep neural network on a large image aesthetics dataset. The unbalanced distribution of aesthetics scores in the training set can result in bias of the trained model towards certain aesthetics levels. Therefore, we propose to add sample weights during training to overcome such bias. Moreover, we build a loss function on the histograms of user labels, thus enabling the network to predict not only the average aesthetics quality but also the difficulty of such predictions. Extensive experiments demonstrate that our model outperforms the previous state-of-the-art by a notable margin. Additionally, we propose an image cropping technique that automatically outputs aesthetically pleasing crops. Given an input image and a certain template, we first extract a sufficient amount of candidate crops. These crops are later ranked according to the scores predicted by the pre-trained aesthetics network, after which the best crop is output to the users. We conduct psychophysical experiments to validate the performance. Apart from cropping, we further present a keyword-based image color re-rendering algorithm. For this task, the colors in the input image are modified to be visually more appealing according to the keyword specified by users. Our algorithm applies local color re-rendering operations to achieve this goal. A novel weakly-supervised semantic segmentation algorithm is developed to locate the keyword-related regions where the color re-rendering operations are applied. The color re-rendering process benefits from the segmentation network in two aspects. Firstly, we achieve more accurate correlation measures between keywords and color characteristics, contributing to better re-rendering
Signalling Effects of Vlogger Popularity on Online Consumers

ABSTRACT This article investigates the effect of video loggers (vloggers) popularity on consumer credibility perception and purchase intention. It employs a two (high versus low vlogger popularity) by two (search versus experience product types) between-subject experimental design to uncover the signalling effect of vlogger popularity. While vlogger popularity influences the consumers’ credibility perception and purchase intention for all products, a high popularity vlogger is likely to be more effective in influencing the online consumers for experience products. We confirm the usefulness of the popularity construct in explaining purchase behavior in social media settings. In doing so, we provide an empirical evidence concerning the specific conditions under which credibility is more (or less) effective in influencing behavior. This study is the first to examine vlogger popularity effects in social media. Our findings provide important insights to both academics and practitioners.
Looking at the Road When Driving Around Bends: Influence of Vehicle Automation and Speed

When negotiating bends car drivers perform gaze polling: their gaze shifts between guiding fixations (GFs; gaze directed 1–2 s ahead) and look-ahead fixations (LAFs; longer time headway). How might this behavior change in autonomous vehicles where the need for constant active visual guidance is removed? In this driving simulator study, we analyzed this gaze behavior both when the driver was in charge of steering or when steering was delegated to automation, separately for bend approach (straight line) and the entry of the bend (turn), and at various speeds. The analysis of gaze distributions relative to bend sections and driving conditions indicate that visual anticipation (through LAFs) is most prominent before entering the bend. Passive driving increased the proportion of LAFs with a concomitant decrease of GFs, and increased the gaze polling frequency. Gaze polling frequency also increased at higher speeds, in particular during the bend approach when steering was not performed. LAFs encompassed a wide range of eccentricities. To account for this heterogeneity two sub-categories serving distinct information requirements are proposed: mid-eccentricity LAFs could be more useful for anticipatory planning of steering actions, and far-eccentricity LAFs for monitoring potential hazards. The results support the idea that gaze and steering coordination may be strongly impacted in autonomous vehicles.
