Consumer Behaviour and Sensory Preference Differences: Implications for Wine Product Marketing

Purpose- Exploratory research was conducted in a well-known Australian wine region to determine the differences in the behaviour dynamics and sensory preferences of consumer groups. The overall aim is to gain some insights into the product style preferences of consumers and what this means in practical terms to wine product marketing. Design/methodology/approach- Information was obtained from a random sample of 150 visitors to ten wineries in the Yarra Valley wine region in Australia. Data were collected by means of self-administration surveys using a highly structured questionnaire at each of the winery tasting room venues. Findings- Specific differences exist in the wine consumption behaviour and sensory preferences of males and females and between generational cohorts, specifically Millennial and older consumers. Females drink less wine than males, spend less thereon but tend to “compensate” for this by buying higher priced wine per bottle, which could represent a risk-reduction strategy. Females are noticeably higher than their male counterparts in white wine consumption, showing a preference for a sweeter wine style at a young age, and reported a strong preference for medium body style wines over light and full-bodied wines. From a sensory preference viewpoint, fruit tastes and aromas are by far the most important, especially among females, as are vegetative characters, wood/oak, and mouth-feel characters. More males, on the other hand, preferred the aged characters of wine. Research limitations/implications- It is possible to target wine consumers in accordance with their gender and lifecycle stage as far as the sensory and certain behavioural aspects of the product are concerned. However, this should not be oversimplified and drive product marketing strategies in the wrong direction. Originality/value- This study is of value to academic researchers, wine industry practitioners and other wine distribution channel members alike, as it provides insights into consumer behaviour differences and one of the core tangible aspects of a wine product, namely the sensory preferences of consumers.
Body Mass Index and Waist Circumference of HIV-Infected Youth in a Miami Cohort: Comparison to Local and National Cohorts

Objectives: Human immunodeficiency virus (HIV)–infected youth are healthier because of effective antiretroviral therapies. We compared anthropometric measurements and prevalence of overweight and obesity between perinatally HIV-infected youth, a local HIV-uninfected comparison group, and 2007 to 2010 National Health and Nutrition Examination Survey (NHANES) data. In addition, we compared only African American HIV-infected youth with NHANES African Americans. Methods: Height, weight, body mass index (BMI), and waist circumference (WC) of HIV-infected youth, aged 10 to 19 years, were compared among groups. BMI percentiles were categorized as underweight (<5%), normal (5% to <85%), overweight (85% to <95%), and obese (≥95%). Clinical correlates were modeled as predictors of BMI and WC. Results: A total of 134 HIV-infected (including 103 African Americans) (mean age 16.5 years), 75 HIV-uninfected (mean age 14.2 years), and 3216 NHANES (including 771 NHANES African Americans) (mean age 15.0 years) youth were included in the analysis. Height and weight z scores of HIV-infected youth were lower than those of HIV-uninfected and NHANES (P ⩽ 0.056) youth. BMI, WC, and BMI category were not statistically different between groups. In the HIV-infected African American group, BMI z score was lower (0.49 vs 0.76, P = 0.04) compared with NHANES African Americans. There were no significant predictors of BMI or WC for the HIV-infected group. Conclusions: HIV-infected children have similar BMIs and WCs as uninfected children both locally and nationally and show similar high rates of obesity and overweight. When compared with a more racially similar African American national sample, HIV-infected children have a lower BMI, suggesting that there may be persistent anthropometric differences in HIV.
Large-Scale Automatic Vessel Monitoring Based on Dual-Polarization Sentinel-1 and AIS Data

This research addresses the use of dual-polarimetric descriptors for automatic large-scale ship detection and characterization from synthetic aperture radar (SAR) data. Ship detection is usually performed independently on each polarization channel and the detection results are merged subsequently. In this study, we propose to make use of the complex coherence between the two polarization channels of Sentinel-1 and to perform vessel detection in this domain. Therefore, an automatic algorithm, based on the dual-polarization coherence, and applicable to entire large scale SAR scenes in a timely manner, is developed. Automatic identification system (AIS) data are used for an extensive and also large scale cross-comparison with the SAR-based detections. The comparative assessment allows us to evaluate the added-value of the dual-polarization complex coherence, with respect to SAR intensity images in ship detection, as well as the SAR detection performances depending on a vessel’s size. The proposed methodology is justified statistically and tested on Sentinel-1 data acquired over two different and contrasting, in terms of traffic conditions, areas: the English Channel the and Pacific coastline of Mexico. The results indicate a very high SAR detection rate, i.e., >80%, for vessels larger than 60 m and a decrease of detection rate up to 40 % for smaller size vessels. In addition, the analysis highlights many SAR detections without corresponding AIS positions, indicating the complementarity of SAR with respect to cooperative sources for detecting dark vessels.
Broadband Strong Ground Motion Simulation of the 2011 Tohoku , Japan , Earthquake

Strong ground motions simulation of the 2011 Tohoku earthquake (MW 9.0) is studied. The record section of acceleration waveforms along the Pacific coast of east Japan exhibits four isolated wave packets propagating from different locations to north and south. A source model that consists of four strong motion generation areas (SMGA) is constructed. Each isolated wave packet is assumed to be contributed by the corresponding SMGA. Firstly the rupture starting points of each SMGA are identified by picking up the onset of individual wave packets. Then the model parameters of these four SMGAs are determined by strong motion simulations using the empirical Green's function method (Irikura, 1986). The obtained source model explains the acceleration, velocity, and displacement time histories in the period range from 0.1 to 10 s at most stations well. SMGA should be appropriately considered in source modelling for strong motion prediction of future great plate-boundary earthquakes.
Effects of Music on Pain, Anxiety and Vital Signs of Children during Colonoscopy

This study aimed to investigate the effect of music on pain, anxiety and vital signs in children undergoing colonoscopy. This was a randomized clinical study. It was carried out on 100 children (7 to 14 years old) requiring colonoscopy. Children were randomly allocated to a control or music group. The music group was played relaxing music (by Clayderman) during the procedure. Spiegelberger and pain questionaires were administered immediately after the colonoscopy. Pulse rate, blood pressure and percent blood oxygen saturation were recorded for each subject. The control group was treated in an identical manner, but was not played music during the procedure. Data were analyzed using SPSS software. Satisfaction, anxiety, pain, and blood pressure were significantly different between the groups (P <0.05), but oxygen saturation and heart rate did not differ significantly (P> 0.05). Music can reduce anxiety and pain during colonoscopy. [Kiani MA, Nagaphi M, Jafari SA, Ghayour MM, Mohammadi S, Saeidi M, Kiani E, Ferns AAG.

Promoting self-efficacy through microteaching in a flipped classroom in US teacher education: focusing on elementary pre-service teacher’s ESL teaching for culturally and linguistically diverse English language learners

This study explores the impact of a flipped classroom, in terms of self-efficacy, for elementary pre-service teachers in US teacher education programs. This research project explores how ESL microteaching activity in the flipped classroom shapes teacher-candidates' self-efficacy regarding teaching culturally and linguistically diverse (CLD) students. By analyzing ESL microteaching videos, pre-service teachers' reflection papers, and individual interviews with the course instructors, the study results show how pre-service teachers enhance their self-efficacy in teaching CLD English language learners in mainstream content subject classrooms. Moreover, the researchers provide suggestions on how teacher educators can utilize the flipped classroom to create an authentic and meaningful learning experience, such as using ESL microteaching for pre-service teachers to shape their self-efficacy in order to be well-prepared for CLD English language learners. The implication is that Korean pre-service teachers should be prepared to teach CLD students in their mainstream classrooms. 요 약 초등예비교사들이 다문화 배경 학습자를 가르쳐 그들의 학업성취도를 높이는 것이 국가적 과제로 떠올랐다. 본 연구 는 초등 예비교사를 양성하는 미국 대학의 예비교사들이 수업시연을 통해 다문화 배경 영어학습자를 가르칠 때 어떻게 자기 효능감이 향상되는지 고찰하였다. 대학의 수업을 플립드 러닝으로 설계하여 수업 전에 내용을 미리 학습한 뒤, 실제 수업시간 에는 다문화 배경 영어학습자 대상 예비교사들의 ESL 수업시연을 연습하였다. 예비교사의 ESL 수업시연 동영상, 예비교사 의 감상문 및 담당교수 인터뷰를 분석한 결과, 내용교과를 가르치는 초등학교 교실에서 다문화 배경 영어학습자를 잘 가르칠 수 있도록 예비교사들은 적절하게 준비되고 있다고 느꼈으며 자기 효능감이 향상되었다. 또한, 본 연구는 교사 교육자들이 플립드 러닝을 활용하여 수업시연과 같은 실제적인 학습 경험을 제공하여 다문화 배경 영어학습자를 잘 가르칠 수 있도록 예비교사를 준비시키는 방안을 덧붙였다. 마지막으로 이상의 연구를 한국의 상황에 적용하여 국제화 시대에 한국의 예비교 사들도 다문화 학생을 가르칠 수 있도록 교사양성기관에서 준비될 필요가 있음을 지적하였다.
Tonal stability modeling from audio chroma features

This work explores the possibility of modeling tonal stability from music signals, in an attempt to approximate in a different way an ubiquitous, yet controversial, topic in music research: that of the perception of tension and relaxation over time. We rely upon some of the most agreed hypothesis about the hierarchical properties of the tonal system, to define a scenario in which such features could be modeled and exploited from audio signals. From the methodological point of view, we reinterpret current paradigms from music theory and cognitive psychology, in order to define a coherent and manageable concept of tonal stability, around the idea of perceptual degree of closeness between tonal events and their tonal contexts. Our proposed algorithm extracts chroma information from music signals and builds a representation in which several hierarchies of pitch events, related with traditional categories of pitches, chords and keys, are simultaneously accessible. The different levels on this keyscape establish the required hierarchical relationships between tonal events and -withintheir tonal contexts. This information is discussed in terms of stability through time and pitch space and, after its mapping into a geometric model of perceptual interkey distances, several metrics of tonal stability are proposed. Through three case studies, we discuss the applicability of the algorithm for cadence finding, tonal tension peaks modeling and stability-based structural analysis.
Be a Fit Kid: Nutrition and Physical Activity for the Fourth Grade

This article describes the inclusion of Be a Fit Kid in the fourth-grade curriculum. Be a Fit Kid is a fitness-emphasized physical activity and heart-healthy nutrition education program for elementary school children. Five parent—education lessons were offered and nutrition workbooks were distributed to parents. Following the 10-week intervention, significant improvements in fitness, body fat, nutrition knowledge, dietary habits, and levels of lipids and lipoproteins were observed in the intervention group compared with baseline levels. Changes in fitness, body fat, and nutrition knowledge were significant compared with the control group. These findings suggest that comprehensive physical activity and nutrition programs included in the school curriculum may be effective for improving cardiovascular health and reducing future risk for lifestyle-related diseases.

A Content Analysis of School Counselors' Legal Experiences through Self-Reflective Letter Writing.

School counselors can write letters to themselves to practice self-reflection and enhance learning from experience. Using inductive and deductive content analysis, we analyzed how twelve school counselors used letters to themselves to reflect on their legal experiences. In their letters, participants demonstrated a wide range of depth in dimensions of self-reflection. Implications for future and current school counselors’ selfreflective practices are provided.
Algebra and Geometry of Hamilton ’ s Quaternions ‘ Well , Papa , Can You Multiply Triplets ?

(right) Sonakshi Sachdev is a PhD student at the Chennai Mathematical Institute. She has worked on the dynamics of rigid bodies, fluids and plasmas. Inspired by the relation between the algebra of complex numbers and plane geometry, William Rowan Hamilton sought an algebra of triples for application to three-dimensional geometry. Unable to multiply and divide triples, he invented a non-commutative division algebra of quadruples, in what he considered his most significant work, generalizing the real and complex number systems. We give a motivated introduction to quaternions and discuss how they are related to Pauli matrices, rotations in three dimensions, the three sphere, the group SU(2) and the celebrated Hopf fibrations.
Does the Principle of Compensation Provide a Solid Basis for Establishing Corporate Environmental Responsibility : A Case Study of Madagascar’s Mining Industry

The mining sector has been criticized for its lack of environmental responsibility, but a certain amount of progress has been evident. At the same time, a number of developing countries have opted for an environmental management framework underpinned by the principle of compensation. Even though this principle is closely aligned to corporate social responsibility, it does not appear to represent the most effective way of achieving corporate social responsibility. Based on a case study in Madagascar, we examine the application of the principle within a mining project and show that its inadequacy stems from failing to consider the population’s response to the actions taken by companies. In our study, the principle of compensation was strictly applied, but the local population began to clear the forest once the mining project was underway. Our findings hence suggest that corporate social responsibility in this kind of context would be more effective if it were based on a stakeholder approach. In addition, our case study sheds new light on how the stakeholder approach should be interpreted.
Effects of REFe 2 on microstructure and magnetic properties of Nd-Ce-FeB sintered magnets

Ce substitution level in Nd-Fe-B magnets has been significantly increased via the binary main phase (BMP) approach, i.e. sintering the mixture of Ce-free and Ce-containing RE2Fe14B (RE, rare earth) powders. REFe2 phase that forms in the high Ce-containing Nd-Ce-Fe-B magnets has been considered to be harmful to magnetic performance due to its soft magnetism. In this work, we found that REFe2 phase with lower melting point than the 2:14:1 phase plays positive role on optimizing the microstructure and retaining magnetic performance of the Nd-Ce-Fe-B BMP magnets. The wettability of 2:14:1 phase can be improved by sintering above the melting point of REFe2 phase, which promotes densification of the magnet and the formation of continuous and smooth grain boundary (GB) phases. This contributes to the weakened short-range exchange coupling between adjacent grains, hence ensures superior magnetic performance of BMP magnets to the single main phase (SMP) ones with the same average composition. As a result, magnetic properties of Br 1⁄4 12.4 kG, Hcj 1⁄4 9.0 kOe and (BH)max 1⁄4 36.7 MGOe can be obtained even when 45 wt % Ce substitutes for Nd in the BMP magnets. © 2017 Acta Materialia Inc.

Studies of the Mechanism of Enhancement of Human Adenovirus Infection in Monkey Cells by Simian Virus 40

The defect which prevents human adenovirus replication in monkey cells and the mechanism whereby this restriction is overcome by coinfection with simian virus 40 (SV40) have been studied. Adenovirus capsid proteins are not synthesized efficiently in monkey cells in the absence of SV40. Adenovirus “enhancement” by SV40 was found to be the product of increased efficiency of replication by a small percentage of cells. This enhancement effect apparently occurred only when SV40 and adenovirus infected the same cells. These findings suggest that the replicative block occurs prior to virion assembly, and an accompanying report seeks to locate the site of restriction more precisely at the post-transcriptional level.
Multiple-Valued Decomposition of Generalized Boolean Functions and the Complexity of Programmable Logic Arrays

Generalized Boolean functions are shown to be useful for the design of programmable logic arrays (PLA's), and the complexity of three types of PLA's is obtained by the theory of multiple- valued decomposition. A two-level PLA consists of an AND array and an OR array, and they are cascaded to perform a two-level AND-OR circuit. A PLA with decoders consists of decoders, an AND array, and an OR array. A three-level PLA consists of a D array, an AND array, and an OR array, and they are cascaded to perform a three-level OR- AND-OR circuit. It is shown that a generalized Boolean function f(X1, X2,··, Xr):X Bni → B, where B = {0,1}, is represented by a generalized Boolean expression of 2<sup>ni</sup>-valued variables X<inf>i</inf>; and f can be directly realized by a PLA with decoders or a three-level PLA. To realize a function of n-variables (n = 2r), the following sizes are shown to be sufficient: for a two-level PLA, (n + ½) 2<sup>n</sup>; for a PLA with two-bit decoders, 4(n + 4) 2<sup>n</sup>; for a three-level PLA, 2<sup>n</sup>+ (3n + l)√2<sup>n</sup>+ 2n<sup>2</sup>Especially in the case of PLA with two-bit decoders, the following sizes are shown to be necessary and sufficient: for an arbitrary symmetric function, 3/2(n + ½) √3<sup>n</sup>; and for a parity function, (n + ½)√ 2<sup>n</sup>.
Vision-Based Probabilistic Map Estimation with an Inclined Surface Grid for Rough Terrain Rover Navigation

This paper describes a novel map representation called Inclined Surface Grid (ISG) maps that provides the ability of modeling traversability of an environment. In order to accomplish safer navigation autonomously with a planetary rover by avoiding hazardous areas, appropriate traversability of the terrain has to be evaluated. In the ISG maps, the patch on each grid stores not only traversability but more detailed information — height, slopes (roll and pitch angle) and roughness. The ISG maps have higher degree-of-freedom knowledge about the surface compared with two-dimensional grid or elevation maps and have very good performance to analyze traversability. In order to assure the reliability of surface estimation in far range areas where the point cloud density decreases, an expanding sampling area approach is introduced to homogenize the point density in a grid by increasing the sampling points. Moreover, probabilistically updating using a stereo vision-specified error model is introduced to estimate the information of each patch. Thus, probabilistic updating allows the ISG maps to yield few failed patches. In the experiment, the resulting geometrical information of our ISG maps converged into an accurate geometry of terrain more than the simple overwriting approach. It is shown that our approach can also create the appropriate traversability map in rough terrain.
Visual positioning systems — An extension to MoVIPS

Due to the increasing popularity of location-based services, the need for reliable and cost-effective indoor positioning methods is rising. As an alternative to radio-based localization methods, in 2011, we introduced MoVIPS (Mobile Visual Indoor Positioning System), which is based on the idea to extract visual feature points from a query image and compare them to those of previously collected geo-referenced images. The general feasibility of positioning by SURF points on a conventional smartphone was already shown in our previous work. However, the system still faced several shortcomings concerning real-world usage such as request times being too high and distance estimation being unreliable because of the employed estimation method not being rotation invariant. In this paper, three extensions are presented that improve the practical applicability of MoVIPS. To speed up request times, both a dead reckoning approach (based on step counting using the accelerometer) and an orientation estimation (based on the smartphones compass) are introduced to filter relevant images from the database and thus to reduce the amount of images to compare the query image to. Furthermore, the vectors of the SURF points are quantized. For this purpose, clusters are calculated from all SURF points from the database. As a result, each image can be represented by a histogram of cluster frequencies, which can be compared with each other a lot more efficiently. The third extension is an improvement of the distance estimation method, which uses the matched feature points of an image to perform a perspective transformation and to determine the actual position with the aid of the transformation matrix.
