Published: June 2017

We have developed highly transparent color liquid crystal display (LCD) using newly developed scattering‐type liquid crystal, which shows transparent state when voltage is not applied, with field sequential color (FSC) driving method without employing color filter and polarizer. Furthermore the light is directly introduced to the panel glass substrates from the edge of the substrates (not from back surface). At surface of the substrates, the light takes a total reflection by difference of refractive index between glasses and air. So the light propagates through the substrate. On the other hand, when a voltage as higher than a threshold voltage (Vth) is applied to liquid crystal (LC) layer, the light is scattered towards the viewers. This newly developed display has high transmittance (80%), wide color gamut and fast response time.
82‐1: Distinguished Paper: Glass Substrate for Micro Display Devices
Authors: Hayashi Kazutaka , Nomura Shuhei , Sakai Yusuke
Published: June 2017

Glass substrate suitable for wearable micro display devices for augmented/virtual reality was developed. This glass has highly matched thermal expansion coefficient with that of silicon and it enables to suppress amount of warpage caused by the boding between Si and glass wafers. The glass also shows lower thermal shrinkage than that of conventional non alkali glass for thin film transistor substrate. In this paper, the effect of the temperature dependence of CTE on warpage generation after bonding process was investigated using both numerical simulation and experiment. The newly developed glass showed remarkably low warpage after the bonding process.
P‐1: Fabrication of a Short‐Channel Oxide TFT Utilizing the Resistance‐Reduction Phenomenon in In‐Ga‐Sn‐O
Authors: Nakata Mitsuru , Ochi Mototaka , Tsuji Hiroshi , Takei Tatsuya , Miyakawa Masashi , Fujisaki Yoshihide , Goto Hiroshi , Kugimiya Toshihiro , Yamamoto Toshihiro
Published: June 2017

The resistance of an In‐Ga‐Sn‐O (IGTO) film with a SiNx /SiOx passivation layer was found to decrease significantly by thermal annealing, due to hydrogen diffusion from the SiNx layer into the IGTO film through the SiOx layer. We propose a method that utilizes this “resistance‐reduction phenomenon” to reduce the effective channel length in IGTO thin‐film transistors with a SiNx /SiOx passivation layer by the partial formation of a low‐resistance region in the IGTO film. The method is experimentally validated, and we show that even shorter channel lengths can be achieved by employing a SiNx /SiOx layer as an etch‐stop layer.

The experiment results demonstrated that the shift of threshold voltage (Vth), which happened during the NBTIS, can induce the dot mura. Then the mechanism and the improvement of dot mura was discussed.

Authors: Liu Chan-Jui , Chen Chien-Tao , Li Hung-Wei , Tsai Chih-Hung , Lu Hsueh-Hsing , Lin Yu-Hsin , Chen Bo-Wei , Chang Ting-Chang
Published: June 2017

Thickness of buffer layers affects performance of flexible polycrystalline silicon thin film transistors (TFT). A thicker buffer SiO2 film demonstrates better endurance to thermal expansion stress from the polyimide substrate. However, the thickness of buffer SiO2 film would causes the variation of optimal excimer laser annealing (ELA) crystallization condition. In addition, the simulation results shows that the non‐uniform stress in the gate insulator is more pronounced near the poly‐silicon/gate insulator edge and at the two sides of the poly‐silicon protrusion. It would affect the stability results and device performance. By optimization the process condition, the device would still have good device performance after operating under high temperature (60 □) and long period of time (500hrs).

Published: June 2017

This work proposes a novel pixel circuit based on amorphous indium‐gallium‐zinc‐oxide thin‐film transistors (a‐IGZO TFTs) for blue‐phase liquid crystal displays (BPLCDs) with the in‐plane switching (IPS) mode.

P‐35: Evaluation of Perceived See‐through Level for Transparent OLED Displays
Authors: Yang Chang-Mo , Kim Choon-Woo , Kwon Hyeok-Jun , Kim Min-Cheol , Ahn Ji-Young , Kim Pu-Reum
Published: June 2017

See‐through capability is an important performance indicator of transparent display. The visibility of the background is affected by the transmittance factor, haze, distance between the transparent display and an object in the background, and the illuminance. In this paper, the perceived see‐through level (PSL) is proposed to represent the degree of visibility of the background. The PSL is determined by considering both transmittance factor and haze. Experimental results indicate that the proposed PSL effectively describes the visibility of the background behind the transparent displays.

It inflicts negative impact on the visual quality of touch products. This paper discusses the mechanism of the interference and also develops an effective model By means of simulation, the model and hence the mechanism is verified. It reveals that if proper mesh period and the gap between LCD and metal mesh are selected, color moiré pattern can be eliminated.

Picturing waters: a review of Photovoice and similar participatory visual research on water governance
Authors: Fantini Emanuele
Published: June 2017

Seeing is one of the main sensory experiences for knowing water and for generating meanings of it. To acknowledge this, visual research methods are increasingly popular in social sciences. In this paper, research using Photovoice or similar participatory visual methods is reviewed in order to assess their potential contribution to the study of water governance. A total of 23 articles related to 20 projects on (1) water, health, and sanitation; (2) participation in water management; (3) landscapes and water spaces; and (4) domestic urban waters, were identified. They are assessed on the basis of the research's purpose, participants, visual outputs, and outcomes. Results are discussed against the three main goals stated by Photovoice's advocates: to record and reflect on communities’ strengths and concerns, to facilitate critical dialogue, and to reach policymakers. We find some evidence about participatory visual methods contribute to the first two goals. However, while most articles assert that Photovoice proved an effective tool for communicating participants’ views to a wider audience and for reaching policy makers, data and analysis on these processes are generally lacking. Documenting and reflecting on these processes are crucial issues that future visual research on water governance should address, particularly in a time when science is increasingly asked to outreach and impact on societal issues.

Background Receiving feedback while in the clinical workplace is probably the most frequently voiced desire of students. In clinical learning environments, providing and seeking performance-relevant information is often difficult for both supervisors and students. The use of entrustable professional activities (EPAs) can help to improve student assessment within competency-based education. This study aimed to illustrate what students’ perceptions are of meaningful feedback viewed as conducive in preparing for performing EPA unsupervised.

Methods In a qualitative multicentre study we explored students’ perceptions on meaningful feedback related to EPAs in the clinical workplace. Focus groups were conducted in three different healthcare institutes. Based on concepts from the literature, the transcripts were coded, iteratively reduced and displayed.

Results Participants’ preferences regarding meaningful feedback on EPAs were quite similar, irrespective of their institution or type of clerkship. Participants explicitly mentioned that feedback on EPAs could come from a variety of sources. Feedback must come from a credible, trustworthy supervisor who knows the student well, be delivered in a safe environment and stress both strengths and points for improvement. The feedback should be provided immediately after the observed activity and include instructions for follow-up. Students would appreciate feedback that refers to their ability to act unsupervised.

Conclusion There is abundant literature on how feedback should be provided, and what factors influence how feedback is sought by students. This study showed that students who are training to perform an EPA unsupervised have clear ideas about how, when and from whom feedback should be delivered.
Does being ‘well off’ help people with epilepsy cope better? The social impact of epilepsy
Authors: Walker Christine , Peterson Chris
Published: June 2017

Introduction Studies demonstrate that there is a positive association between socioeconomic status (SES) and personal control where higher SES groups are likely to have higher personal control and better health outcomes. People with epilepsy however usually show lower levels of personal control. This paper aims to explore the relationship between self-rated prosperity and personal control in an epilepsy sample.

Methods Using the results of the 2013 Australian Epilepsy Longitudinal Survey (AELS) a group was identified who perceived themselves as prosperous or very comfortable. Hypothesising that prosperity would provide greater personal control, we compared this group with other groups from HILDA Wave 11, a random sample of the Australian population surveyed in 2011. HILDA is a household, labour and income study funded by the Australian government.

Results All respondents in Wave 3 (AELS) had lower levels of personal control than the HILDA Wave 11 groups. In a comparison between Wave 3 of those reporting themselves as prosperous or very comfortable with similar groups in HILDA Wave 11, prosperous people from Wave 3 demonstrated much lower levels of personal control than the HILDA Wave 11 group.

Conclusion Personal control is considered to have far-reaching consequences for people's health. The effects of stigma and the unpredictability of epilepsy far outweigh the effects of prosperity for people with epilepsy compared to a random sample of the Australian population.

Introduction

In North Africa and the Middle East, studies about dementia prevalence are scarce. A pilot study was conducted in Lebanon to assess dementia prevalence, using the Arabic‐validated 10/66 Dementia Research Group (DRG) diagnostic assessment for case ascertainment. The study also examined care arrangement and access to care.

Methods

A random sample of 502 persons older than 65 years and their informant were recruited from Beirut and Mount Lebanon governorates through multistage cluster sampling.

Results

The crude and age‐standardized dementia prevalences were 7.4% and 9.0%, respectively. People with dementia were mainly cared for by relatives at home. Access to formal care was very limited.

Discussion

Dementia prevalence in Lebanon ranks high within the global range of estimates. These first evidence‐based data about disease burden and barriers to care serve to raise awareness and call for social and health care reform to tackle the dementia epidemic in Lebanon and in North Africa and the Middle East.
Moral values and good citizens in a multi-ethnic society: A content analysis of moral education textbooks in Malaysia
Authors: Tan Bee Piang , Mahadir Naidu Noor Banu , Jamil Osman Zuraini
Published: June 2017

One of the most important roles of schools is to enable students to become good citizens, capable of participating in the public affairs of society. However, the term ‘good citizens’ evokes different interpretations and definitions in different value systems. Using the methods of quantitative content analysis and narrative analysis, this paper aims to identify the dominant moral values of a good citizen that are conveyed by Malaysian moral education textbooks. The findings demonstrate that ‘responsibility’ is the dominant value for shaping a good citizen in Malaysia. The value of responsibility in the textbooks embraces not only the meanings of self-obligation and accountability, but responsibility is also defined as an individual's sense of self-discipline in their behaviour that enables them to avoid conflict and strive for harmonious social order. The other important values are “Respect”, “Helpful”, “Hard-working” and “Caring”. This study provides an example of how a multi-ethnic nation state like Malaysia promotes these moral values through its educational curriculum, for political legitimacy and forging national unity.
Relationship Between Use of Videogames and Sexual Health in Adult Males

Published: June 2017

Background

Videogame use is increasingly prevalent in people of all ages, and despite the wide amount of scientific evidence proving a role for electronic entertainment in human health, there is no evidence about the relation between use of videogames and sexual health.

Aim

To investigate the association between use of videogames and male sexual health.

Methods

We administered the two validated questionnaires, the Premature Ejaculation Diagnostic Tool (PEDT) and the International Index of Erectile Function (IIEF-15), to men 18 to 50 years old recruited through social networks and specific websites. In addition to the questionnaires, volunteers were asked to provide information on their gaming habit and lifestyle.

Outcomes

An extended version of the IIEF-15 and PEDT, including data about gaming habits and relevant lifestyles.

Results

From June 18, 2014 through July 31, 2014, 599 men 18 to 50 years old completed the questionnaires. One hundred ninety-nine men reported no sexual activity during the previous 4 weeks; four records were rejected because of inherent errors. The remaining 396 questionnaires were analyzed, with 287 “gamers” (playing >1 hour/day on average) and 109 “non-gamers” providing all the required information. We found a lower prevalence of premature ejaculation in gamers compared with non-gamers (mean PEDT score = 3.57 ± 3.38 vs 4.52 ± 3.7, P < .05, respectively). Analysis of the IIEF-15 showed no significant differences between gamers and non-gamers in the domains of erectile function, orgasmic function, and overall satisfaction. Median scores for the sexual desire domain were higher for non-gamers (median score [interquartile range] 9 [8–9] vs 9 [8–10], respectively; P = .0227).

Clinical Implications

These results support the correlation between videogame use and male sexual health. Compared with non-gamers, men playing videogames for more than 1 hour/day were less likely to have premature ejaculation but more likely to have decreased sexual desire.

Strengths and Limitations

This is the first study aimed to assess male sexual health in gamers. We identified an association between PEDT and IIEF scores and videogame use; however, these findings require validation through interventional studies. Furthermore, volunteers were recruited through social networks, thus increasing the risk of recruitment bias.

Conclusion

To our knowledge, this is the first observational study investigating the link between electronic entertainment and male sexuality, specifically for ejaculatory response and sexual desire.
Public Opinion and Politics in the Late Roman Republic
Authors: Rosillo-López Cristina
Published: June 2017

This book investigates the working mechanisms of public opinion in Late Republican Rome as a part of informal politics. It explores the political interaction (and sometimes opposition) between the elite and the people through various means, such as rumours, gossip, political literature, popular verses and graffiti. It also proposes the existence of a public sphere in Late Republican Rome and analyses public opinion in that time as a system of control. By applying the spatial turn to politics, it becomes possible to study sociability and informal meetings where public opinion circulated. What emerges is a wider concept of the political participation of the people, not just restricted to voting or participating in the assemblies.
The Marshall Islands Judgments and Multilateral
Disputes at the World Court: Whither Access to International
Justice?
Authors: Proulx Vincent-Joël
Published: June 2017

The International Court of Justice (ICJ) has mostly emphasized substance over
form and developed a pragmatic, flexible, objective, and fact-based analytical
approach to jurisdiction. That is until a recent series of judgments veering
towards jurisdictional formalism. However, to truly reflect its designation as
the “World” Court, the UN's principal judicial organ must
surely adjudicate some of the “big cases” with global security
implications and involving important obligations erga omnes
beyond strictly bilateral dynamics: the Marshall Islands cases
were as good contenders as any for the Court to enhance its legitimacy
capital.1 As a
corollary, accepting this role might entail that the Court interpret its
jurisdiction in a flexible and progressive manner, which had always been its
mantra up until recently, so that the “big cases” have a chance of
getting their foot in the door and being litigated.
On Form, Substance, and Equality Between States
Authors: Galindo George R. B.
Published: June 2017

The International Court of Justice (ICJ)’s 2016 judgments on the three
cases Obligations concerning negotiations relating to cessation of the
nuclear arms race and to nuclear disarmament show the omnipresence
of the dichotomy between form and substance in the Court's case-law.
Commentators and several dissenting judges have stressed that the judgments
represent a landmark in the sense that the Court has radically
departed from the consideration of flexible standards in applying
procedural rules to the determination of the issue of identification of a legal
dispute. In other words, it made form prevail over substance.
Unlocking collections at the John Rylands Research Institute, University of Manchester Library
Authors: Halkyard Stella
Published: June 2017

In 2013 a new research institute or ‘Arts Lab’ was set up at the University of Manchester. The John Rylands Research Institute (JRRI), based in the John Rylands Library, is a unique partnership between the University of Manchester (UofM) Library and the Faculty of Humanities at the university. Its aim is to establish an internationally renowned centre for research that attracts, and supports work by local, national, or international scholars on the library's special collections. By bringing together a multi-disciplinary team of library professionals, humanities scholars, students and scientists, new approaches are being developed within the JRRI to increase and improve our understanding of these collections, in all their richness and diversity. This piece will provide insights into the work of the JRRI and through a specific case study it will demonstrate how some of the works of art in the library are beginning to benefit from the research carried out under its umbrella. However, it is first necessary to explain why these collections merit such intensive investigation.
