Visual Field Examination in Glaucoma Patients : Humphrey Visual Field Analysis vs Amsler Grid

Introduction and Objective: Glaucoma is the leading cause of global irreversible blindness, signed by glaucomatous optic neuropathy related to visual field defect. The purpose of the study is comparing visual field defect examination using HVFA to Amsler Grid in glaucoma patient at dr. Kariadi Hospital. Methods: This is a cross-sectional study. Amsler Grid were performed to the patients who have reliable HVFA at last 6 months and presented as descriptive analytic results. Result: There were 40 eyes involved in this study from 27 patients (15 men, 12 women), 26-68 years old and visual acuity 1/60-6/6. Seventeen eyes showed visual field defect in HVFA and Amsler Grid had average MD - 24.97 dB, CDR 0.89 and RNFL thickness 51.74. We found that 11 eyes didnâ€™t showed in both of examination had average MD -8.06, CDR 0.63 and RNFL thickness 103.23 and those parameters are significantly different to the 17 eyes before (p<0.05). Data from 12 eyes that showed visual field defect only one of examination (9 only in HVFA and 3 in Amsler Grid) didnâ€™t show difference statistically each other. Conclusion: HFVA and Amsler Grid seemed to be comparable in detecting visual field defect in advanced glaucoma.
(Meta)Modeling "Constitutive Communication": Toward a Real-Time Reflexive Infrastructure for Coordination and Codesign

ions of complex responsive coordination mechanisms. The general middleware approach of treating configuration as constitutive may resonate with understandings of design as configuration work. However when compared to the theoretical depiction of communication-as-constitutive outlined in the previous chapters (to extend to communication-in-design and design-in-communication), the configuration of preexisting elements and components is a limited realization of communicative complexity, insofar as the components and their functionality are already black-boxed and reified before being entered into configurations. While ambiguity, extensibility, and complex notions of identity and equality improve the potential richness of configuration, the infrastructures considered above do not provide a full model of communication-as-constitutive, since only a limited type of communication (articulation of configurations) is involved in specifying structure. This notion of configuration as constitutive differs from the metamodel approach above, in that communication within these systems, as interaction between participants, can only be constitutive in limited ways, limited to explicit sorts of configuration (i.e. articulation work).
Teach-In: Positive Responses during Divisive Times

ABSTRACT In response to the well documented divisiveness throughout the 2016 presidential campaign, faculty members at one university developed a “teach-in” to help students identify and respond to the resulting difficult communications in positive ways. This was accomplished through planned activities implementing micro/macro theories and skills. In March 2017, as part of Social Work Month, 71 BSW and MSW students participated in a Teach-in event. Paired sample t-tests showed significant differences between pre-post test scores on seven measured items. The teach-in appeared to be successful in increasing student preparedness to talk to individuals with differing political opinions through self-reflective participatory exercises related to their own (and conflicting) political perspectives, knowledge related to understanding contemporary political conflicts, and instruction on positively and professionally responding to divisive communications. Social work educators are important catalysts in helping students effectively respond to and advocate for those threatened during these divisive times. Teach-ins may also be an appropriate tool for addressing contemporary issues when curriculum requirements provide limited options for additional elective course offerings.
Electronic Word-Of-Mouth (eWOM) Behavior in Malaysia: Successful Marketing Strategy

The major purpose of this research is to discover the influences of Active User of Social Media (AUSM), Innovativeness and Trust towards electronic word of mouth (eWOM) behaviour in Malaysia. Enormous past research on the electronic word-of-mouth, but only few have analysed the topic from Malaysian perspective. A quantitative method was adopted in this study and responses from 120 respondents in Malaysia that were analyzed using PLS-SEM. The result shows that there are significant relationship between active user of social media (AUSM), innovativeness and trust toward eWOM behaviour among Malaysian. Practically, the result indicate that electronic word of mouth behaviour via social media and mobile technology can be part of marketing strategy in promotion to influence buyer to increase sales of product of a company. This empirical study attempts to enrich the understanding of electronic word of mouth behaviour via social media and mobile technology in Malaysian context.
Informational Efficiency in Securitization After Dodd-Frank

We analyze how Dodd-Frank-mandated risk retention affects the information investors extract from issuers’ retention choices in the CMBS market. We show that the required retention level is both binding and stringent. Although this implies issuers cannot signal using the level of retention, we provide a model showing that signaling can occur by varying the retention structure. The model is consistent with spreads being empirically lower in deals with a purely first-loss retention structure. A stated concern of rulemakers is asymmetric information. However, we show that, post-crisis, the level of asymmetric information in this market is quite low.
Using EBG to improve antenna efficiency in proximity to the human body

This paper presents a 2.45 GHz patch antenna over an EBG substrate with the objective of higher radiation efficiency and compact operation in close proximity to a lossy medium, both of which are critical for body worn antennas. To achieve compact size, several sizes of EBG are included and the individual antenna efficiency and radiation pattern are studied. From these results, the EBG substrate demonstrates great improvement of the antenna efficiency but its size has a considerable effect on efficiency when the antenna is used in close proximity to the human body.
The Impact of Social Influence, Gender, and Non-Parental Guardianship on Adolescents in Substance Use Recovery

This study explored potential barriers to sustaining recovery from substance use disorders (SUD) in adolescence, particularly for youth enrolled in school-based recovery programs, or recovery schools. Participants (N = 28) enrolled full-time in a Massachusetts recovery high school completed a survey of demographic information and scales assessing social desirability, parent and peer influence, and stigma. Results indicated that peers have slightly higher influence than parents, particularly among girls and adolescents with non-parental guardians. Participants living with parents who use substances reported being sober an average of 28.7 months, versus 40.9 months for those living with nonusing parents. Participants with parental guardians also reported experiencing significantly greater social desirability when there is no family history of substance abuse.
Spectrum of imaging findings in pulmonary infections. Part 1: Bacterial and viral

Chest radiography is generally the first imaging modality used for the evaluation of pneumonia. It can establish the presence of pneumonia, determine its extent and location, and assess the response to treatment. Computed tomography is not used for the initial evaluation of pneumonia, but it may be used when the response to treatment is unusually slow. It helps to identify complications, detect any underlying chronic pulmonary disease, and also to characterise complex pneumonias. Although not diagnostic, certain imaging findings may suggest a particular microbial cause over others. Knowledge of whether pneumonia is community-acquired or nosocomial, as well as the age and immune status of the patient, can help us in narrowing the differential diagnoses. The purpose of this article is to briefly review the various pulmonary imaging manifestations of pathogenic organisms. This knowledge along with clinical history and laboratory investigations of the patient may help in guiding the treatment of pneumonia.
It is All in the System's Parameters: Privacy and Security Issues in Transforming Biometric Raw Data into Binary Strings

Biometrics traits such as faces, fingerprints, and irises, are becoming prevalent in computer security applications: from authentication systems to identification systems. Given the sensitive nature of biometrics, a great deal of effort is put into protecting the biometric data after it is acquired — from secure sketch and fuzzy extractors to the use of secure multiparty computations (in protocols such as SCiFI or GSHADE). While these solutions make sure that the extracted values (e.g., binary strings or vectors) that correspond to the biometrics are kept privately and securely, their practical implementations are not optimal with respect to privacy guarantees in the process of extracting the information from the raw biometric data. This paper analyses current solutions for protected systems and discusses the existing and potential problems in the security and privacy of their feature extraction and the binarization processes. As an illustrative example, we show a PoC of an attack on a feature extraction solution from facial images, used in several protected systems, and show that it reveals information which is very close to the training image of the user. As we argue in this paper, other solutions provide privacy for the system's users but make use of external set of biometric data which is often quite large, thus facing privacy and ownership issues associated with the external set of people. The take home message of this paper is: Many of the existing “privacy preserving” solutions neglect the privacy and security aspects of the feature extraction and binarization processes. Hence, we urge future research to close this gap in the security and privacy of biometric systems.
Effects of translanguaging as an intervention strategy in a South African Chemistry classroom

ABSTRACT The study sought to investigate the role played by language in the academic performance of science students at a high school in the Free State province, South Africa who are taught through a language different from their mother tongue. The paper reports on the decisive mantle language plays in the comprehension and subsequent scholastic performance of these Chemistry students. The study adopted a mixed method research design in which the participants were randomly assigned to either the control or experimental group using Research Randomizer. Participants in the experimental group were bestowed intervention in form of lessons and learning materials in their mother tongue. Responses were drawn from a sample of 30 tenth grade students on the role language plays in the tutelage of tenth-grade Chemistry. Data was gathered from three tests written by the participants as well as from interview responses. A paired t-test disclosed a statistically significant difference in the academic achievement of the two research groups in the posttest. The upshot affirms that the employed paradigm shift, where languages of input and output were deliberately interchanged, proved to be an indispensable instructional approach as these Chemistry students were accorded the opportunity to learn in their home language. The present research findings are in line with previous research which affirms the use of students’ mother tongue as being a social practice that goes beyond the four walls of the classroom.
Döviz Kuru Değişkenliğinin Türkiye’nin Euro Kullanan Ülkelere İhracatı Üzerindeki Etkisi

This paper investigates the impact of real exchange rate volatility on the Turkey’s export to the Euro 12 countries. Econometric analysis bases on panel data methods and uses quarterly data for the years after 2002 when Euro entered into circulation in these countries. Estimation results indicate that real exchange rate volatility affects Turkey’s export to the Euro using countries in a low level negatively and not in a permanent manner. Furthermore it is found that reel exchange rate does not affect Turkey’s export to these countries.
El tránsito de la escuela pública a la escuela privada en el sector emergente de Lima Metropolitana : ¿Buscando mejor calidad?

The massive transit from public to private school in the emerging sector tends to be considered as a response to the low quality of public education. This study argues that the private option would be also responding to the formation of a disposition or habitus that makes that this option be assumed inertial and automatically by families as a realization of an aspirational logic within their path of upward social mobility. Through the exploration of the processes of school choice in a sample of emerging families the study shows how the decision-making processes are mediated by the search for a balance among different criteria which include costs, material conditions of schools, its location and closeness, the pursuit of getting safe places for their children or the student-teacher ratio, among others. In addition, their decisions are strongly influenced by the strategies of identification and social differentiation in the school space. The parents’ strong commitment with the education of their children and the social composition of the families that make up a school are relevant factors for both the identification of those «as one», and the differentiation and exclusion of those who represent «the other», marking a distance from families who send their children to public school or schools of fewer resources. This study seeks to introduce into the debate a better understanding of the process of school choice that goes beyond the search for quality and includes more complex social processes.
Research on Trade Credit and Bank Credit Based on Dynamic Inventory

Trade credit is a short-term business financing based on purchases between the retailer and the supplier. This paper considers a supply chain consisting of a well-funded supplier and a capital-constrained retailer. At the beginning of each sales season, the retailer need to place an order from the supplier to meet the stochastic demand. The capital-constrained retailer determines the order quantity and whether to borrow loans from a bank or the supplier or just use its initial capital, according to its finance and stock status with the wholesale price provided by the supplier. We build the Stackelberg game with the supplier as the leader and divide the retailer’s initial inventory and capital into different wealth regions to discuss the optimal strategies of different wealth regions. We extend to the two-period dynamic financing model based on dynamic inventory and capital flow so as to obtain the optimal strategy matrix of the retailer and the supplier under bank and trade credit. Numerical results validate our theoretical analysis of bank credit and supplier credit with dynamic inventory under different period setting.

The effects of metaphonological awareness training on L3 Mandarin tone acquisition by Cantonese learners

ABSTRACT According to the speech learning model [Flege, J. E. (1995). Second language speech learning: Theory, findings, and problems. In W. Strange (Ed.), Speech perception and linguistic experience: Issues in cross-language research (pp. 233–277). York Press], learners whose first language (L1) is a tonal language (e.g. Cantonese) can be confused by similar yet different tones in their L1 and another tonal language (e.g. Mandarin). Encouraged by the biliteracy and trilingualism language policy in Hong Kong, L1 Cantonese learners of Mandarin have been committed to learning the third language (L3) Mandarin tones but are struggling with that task. The main purpose of this study is to examine Cantonese learners’ perceptions and production of Mandarin tones, and to investigate learners’ performance in production tasks before and after implementing metaphonological awareness protocols. Twenty-five Cantonese learners studying at a local university were recruited to complete the production, perception and verbal protocol tasks. Based on Wrembel’s [2015. Metaphonologcial awareness in multilinguals: A case of L3 Polish. Language Awareness, 24(1), 60–83. https://doi.org/10.1080/09658416.2014. 890209] framework, this study categorised the participants’ statements of metaphonological awareness shown in their self-correction and self-reflection performances in the introspective and retrospective protocols. The error rates and patterns in the production and perception tasks were analysed. Metaphonological awareness training has a significant positive effect on improving learners’ Mandarin tone pronunciation.
Student Academic Streaming Using Clustering Technique

The balance of human capital supply and industry demands are crucial to sustain a competitive advantage in order to ensure stability of economic growth. Unfortunately, companies often find it hard to recruit the right people. Many ideas obviously relate to connect human capital to education because human capital is created through education. In the education sector, there is a critical need to develop an effective planning mechanism to distribute the students into the most suitable area in the industry. In order to achieve this, the student’s pathway needs to be planned systematically in school by identifying the student’s streaming based on their academic performance. In this case, students who have the same performance will be grouped in the same cluster using a data mining technique. However, the problem is that, it is difficult to identify real potential for the students, because their performance is not well monitored, and current assessment systems do not support the student’s academic planning activities. Besides, there is no specific technique used to group students into clusters based on their performance. This study aims to overcome the problem by grouping the students according to their performance using clustering techniques and to propose a suitable model. This study aims to overcome the problem by identifying a suitable clustering model that can be used to analysis an educational data. The data involves is student performance data. Based on the data, two clusters of students are created which is science and arts. A novelty in the method of study is the use of three clustering models and a comparison among them in order to find a suitable clustering model to be used with student academic performance data. The study was conducted in five schools in Malaysia to support students’ grouping in two different academic streams, which are science and art. The result demonstrated the best model of clustering technique that is suitable for mining the educational data. Moreover, suitable streaming based on the students’ performance and education policy was created from the results. It can be used to assist schools and students in determining the appropriate streaming for the students, and support for the human capital needs by the country in the future .

Railway obstacle detection algorithm using neural network

Aiming at the difficulty of detection of obstacle in outdoor railway scene, a data-oriented method based on neural network to obtain image objects is proposed. First, we mark objects of images(such as people, trains, animals) acquired on the Internet. and then use the residual learning units to build Fast R-CNN framework. Then, the neural network is trained to get the target image characteristics by using stochastic gradient descent algorithm. Finally, a well-trained model is used to identify an outdoor railway image. if it includes trains and other objects, it will issue an alert. Experiments show that the correct rate of warning reached 94.85%.
On the reciprocal relationship between attention and visual working memory.

ON THE BIDIRECTIONAL RELATIONSHIP BETWEEN ATTENTION AND VISUAL WORKING MEMORY Blaire Dube Advisor: Dr. Naseem Al-Aidroos University of Guelph, 2019 Visual attention and visual working memory—VWM; our short-term storage system for visual information—are both inherently limited in their processing capabilities, yet critical to process, and navigate through, our complex visual environments. How is it that attention and VWM support efficient visually guided behaviour? A longstanding theory addressing this question centers on the role of attention in regulating how we use VWM, suggesting that attention serves as a filter to VWM, restricting access to goal-consistent information. The relationship between attention and VWM, however, is more complex than this theory suggests and, moreover, is reciprocal in nature—attention influences the way information is encoded in VWM and, in turn, the contents of VWM guide subsequent attention. As such, the goal of the present thesis is to explore the bidirectional interactions between attention and VWM, with a focus on the flexibility with which the individual mechanisms operate, to extend our understanding of how attention and VWM, although inherently limited, support efficient behaviour. Here I demonstrate that attention regulates the flexible distribution of resources in VWM, but also that its contents can be flexibly prioritized to serve different behavioural needs. Overall, top-down control influences the way attention and VWM interact as part of a larger system that ultimately guides behaviour.
De-Identification of Personal Information

De-identification removes identifying information from a dataset so that individual data cannot be linked with specific individuals. De-identification can reduce the privacy risk associated with collecting, processing, archiving, distributing or publishing information. De-identification thus attempts to balance the contradictory goals of using and sharing personal information while protecting privacy. Several U.S laws, regulations and policies specify that data should be deidentified prior to sharing. In recent years researchers have shown that some de-identified data can sometimes be re-identified. Many different kinds of information can be de-identified, including structured information, free format text, multimedia, and medical imagery. This document summarizes roughly two decades of de-identification research, discusses current practices, and presents opportunities for future research.
