Navigation and Bearing Estimation Tasks in 360 ° Video Interfaces for 2 D Desktop Displays

360° field of view (FOV) is becoming a vital part of various human-robot/computer applications, such as urban search and rescue task. Despite growing importance of 360° FOV, very few studies have assessed the effect of 360° visual display on users' remote spatial ability, specifically in the case of 2D 360° User Interface (UI), which is the focus of the current study. We aim to evaluate the efficacy and efficiency of desktop 360° display designs on teleoperators' egocentric spatial ability, specifically navigation and direction judgment in an unknown environment. A previous study[1] showed an advantage of the segmented interface over seamless 360° UI on angle estimation error. However, we are still not clear as to the determining factors that lead to a difference in interface interaction ability. We conducted two studies that studied the scanning effort while using a 360° interface and the ability to estimate the mental egocentric bearing of a target in an environment. We measured the effects of gaming experience, and time constriction, with metrics consisting of time to task completion, target bearing estimation, and latency of target estimation. Further data was collected by an eye-tracking device to help support and complement the data from the studies. We found that gaming experience is a significant positive factor in accuracy and time to task completion. Further, a seamless panoramic view was found to be least effective compared to a segmented interface view of the 360° video feed for target bearing estimation across the entire field of vision presented through the interfaces. Eye tracking data supports the behavioral data collected. It was found that the estimation frequencies in the first study were high for forward heading direction, which was seen in the increased eye movement activity in the same region. In the second study, it was found that angle estimation error was the lowest along mental egocentric axes. This was again observed in the eye tracker data that reported increased activity along the mental egocentric axes.
Monocyte MRI Relaxation Rates Are Regulated by Extracellular Iron and Hepcidin

Many chronic inflammatory conditions are mediated by an increase in the number of monocytes in peripheral circulation, differentiation of monocytes to macrophages, and different macrophage subpopulations during pro- and anti-inflammatory stages of tissue injury. When hepcidin secretion is stimulated during inflammation, the iron export protein ferroportin is targeted for degradation on a limited number of cell types, including monocytes and macrophages. Such changes in monocyte iron metabolism raise the possibility of non-invasively tracking the activity of these immune cells using magnetic resonance imaging (MRI). We hypothesized that hepcidin-mediated changes in monocyte iron regulation influence both cellular iron content and MRI relaxation rates. In response to varying conditions of extracellular iron supplementation, ferroportin protein levels in human THP-1 monocytes decreased two- to eightfold, consistent with paracrine/autocrine regulation of iron export. Following hepcidin treatment, ferroportin protein levels further decreased two- to fourfold. This was accompanied by an approximately twofold increase in total transverse relaxation rate, R2*, compared to non-supplemented cells. A positive correlation between total cellular iron content and R2* improved from moderate to strong in the presence of hepcidin. These findings suggest that hepcidin-mediated changes detected in monocytes using MRI could be valuable for in vivo cell tracking of inflammatory responses.
What does coaching have to offer to young people at risk of developing mental health problems? A grounded theory study

Objectives:This study sought to identify what coaching psychology has to offer young people at risk of developing mental health problems.Design:The study used a semi-structured interview design and self-reflective data analysis within a qualitative approach.Method:Grounded theory was employed to analyse the transcripts and self-reflective data from coaches and young people and to build a series of descriptive and conceptual codes, and in the creation of a theoretical model.Results:The study results in a theoretical model, which suggests the experience of coaching creates a process, a positive relationship and a set of skills where the young person, through growing accountability, awareness and responsibility, develops choice and control over their thoughts, feelings and behaviour. This helps them to deal with their situations.Conclusions:The study results in an initial theoretical model to assist with the application of coaching interventions, targeted specifically at young people at risk of developing mental health problems. It provides a tentative theoretical understanding that requires further research.
Petrology of carbonate beds from the stratotyPe of the carnian (stuores Wiesen section, dolomites, italy): the contribution of Platform-derived microbialites

12 abstract The modal composition of carbonate grains in para-autochthonous carbonate beds from the Ladinian-Carnian stratigraphic succession of Stuores Wiesen in the Dolomites was evaluated by point-counting. The stratigraphic series of Stuores, which includes the GSSP of the Carnian stage, is mostly composed of shales and marls deposited in a rather deep-water setting, at the foot of high-relief carbonate platforms. Numerous cmto dm-scale calciturbidite beds, ranging from carbonate mudstone-siltstone to rudstone, are intercalated within the fine siliciclastics. In the Ladinian lowermost Carnian portion of the succession, many of these calciturbidites are mixed carbonate-siliciclastic. Most of the carbonate grains in the granular facies of Stuores are fragments of microbialite with clotted peloidal fabric, Tubiphytes, calcimicrobes, peloids, ooids, mollusks, echinoderms and other types of skeletal grains. The major constituents of the carbonate grain associations are microbialitic allochems of various types, accounting for 64% of the volume of carbonate on average, with peaks of ca. 90%. This is in agreement with estimates on in-situ microbial-metazoan boundstones of the Dolomites with approximately the same age, and suggests that not only boundstone facies, but also basinal calciturbidites faithfully register the modal composition of microbial carbonate platforms. It is presently impossible to reconstruct the provenance of these microbialites within the depositional profile of the carbonate platform, because the formation of microbialites is not restricted to the photic zone: microbial carbonates may form at water depths of 0 to 250 m and below. Ooids are commonly associated with coarse terrigenous sand, and often grew on siliciclastic nuclei, demonstrating that siliciclastics were encroaching the submerged shelf on adjacent platforms. Overall, terrigenous supply did not hamper the development of high relief carbonate platforms during the Late Ladinian Early Carnian at Stuores, but seems to have had an influence on carbonate grain associations. Fine carbonates contain calcareous nannofossils, which however contribute minimally to the sediment budget at Stuores. 1 Department of Geosciences, University of Padova, Italy; nereo.preto@unipd.it 2 Leibniz Center of Marine Tropical Ecology, Bremen, Germany
Factored Neural Machine Translation at LoResMT 2019

Low resource languages face a major challenge in developing machine translation systems due to unavailability of accurate and parallel datasets with a large corpus size. In the present work, Factored Neural machine Translation Systems have been developed for the following bidirectional language pairs: English & Bhojpuri, English & Magahi, English & Sindhi along with the uni-directional language pair English - Latvian. Both the lemma and Part of Speech (PoS) tags are included as factors to the surface-level English words. No factoring has been done on the low resource language side. The submitted systems have been developed with the parallel datasets provided and no additional parallel or monolingual data have been included. All the seven systems have been evaluated by the LoResMT 2019 organizers in terms of BLEU score, Precision, Recall and F-measure evaluation metrics. It is observed that better evaluation scores have been obtained in those MT systems in which English is the target language. The reason behind this is that the incorporation of lemma and pos tags factors for English words has improved the vocabulary coverage and has also helped in generalization. It is expected that incorporation of linguistic factors on the low resource language words would have improved the evaluation scores of the MT systems involving those languages on the target side.
Deaf students’ access to higher education in Greece

In 1983 the Greek Parliament approved a bill that enabled deaf graduates of high schools (amongst others) to be admitted to institutions of higher education without having to take entrance examinations. Until very recently the education of deaf children in Greece has been based on the exclusive use of the oral approach (i.e. the use of spoken Greek as the language of instruction and excluding the use of Greek Sign Language). The educational attainments of Greek deaf children on completing their school education have been poor compared to those of hearing children and, it has been argued (Lampropoulou 1994), has resulted in the situation that many Deaf people are poorly prepared for participation in society. In light of this situation I investigated the experiences of Deaf students who have availed of the opportunity provided by the above law to enter higher education. The subjects of the study are deaf people whose first or preferred language is Greek Sign Language (GSL) who, hereafter, are referred to as Deaf (spelt with an upper case 'D') people. The samples of Deaf students were made up of students who had graduated, interrupted their studies, were studying or were about to commence their studies at a Greek institution of higher education. In addition I obtained the views of schoolteachers of deaf children, higher education lecturers and representatives of the Greek Federation of the Deaf Brief overviews of the Greek education system and different models of d/Deafness are provided as way of background to the study. The data obtained from interviews with the above groups are presented and discussed, and include proposals as to how access for Deaf students to Greek higher education can be improved. The author hopes that this study will be seen as a contribution to the education of Deaf people in Greece. It provides suggestions for consideration by Greek Deaf and hearing people interested in the education of Deaf people, as well as public and private organisations, as to how improvements in Deaf people's education in Greece can be achieved.
Aquatic Insect Taxa as Indicators of Aquatic Species Richness , Habitat Disturbance , and Invasive Species Impacts in Hawaiian Streams

In this study we provide a synthesis of numerous stream assessments in the Hawaiian Islands that began in the early 1990s and have continued to the present. Data from numerous sites within the five major high Hawaiian Islands with flowing streams (excluding Läna‘i, which lacks flowing waters) were used to assess native and introduced aquatic insect communities, the impacts of various invasive freshwater species and the threats from habitat disturbance. The primary objective of this study was to provide the first comprehensive analysis of aquatic insect populations in various urbanized and virtually pristine stream reaches on the five major Hawaiian Islands, and to assess if various suites of introduced aquatic species may be impacting aquatic insect populations. We were also interested in assessing the suitability of native aquatic insects as key indicator, flagship, or umbrella species regarding the overall health of Hawaiian aquatic ecosystems. If key indicator species can be found, then aquatic habitats with high native biodiversity can be identified and management efforts can be made to ensure this high level of biodiversity persists. These indicator species could also be used for monitoring future rehabilitation programs on disturbed streams.
Highs and lows : Reconstructing tone in proto-Ambel

Ambel is a South Halmahera-West New Guinea (SHWNG) language, spoken in the Raja Ampat archipelago (West Papua, Indonesia). There are two main dialects of Ambel: Metsam, spoken in two villages to the south of the Ambel area, and Metnyo, spoken in the nine remaining Ambel villages. Both dialects have tonal word-prosodic systems (Author forthcoming). The most salient difference between the two dialects is in the tonal phonologies. In this talk, I will present comparative data from monosyllabic cognates in the two dialects, as a first step towards reconstructing the tone system of proto-Ambel. The tone system of Metnyo Ambel is binary and privative: High (H) syllables contrast with toneless (Ø) syllables, leading to minimal pairs such as tún ‘moon’ vs. tun ‘thorn’. Utterance-medially, H syllables are realized [H], and Ø syllables are realized [L]. While work on the tone system of Metsam Ambel is still preliminary, monosyllabic words can be divided into three groups, depending on the utterance-medial realization: those realized [H] (e.g. páy ‘heron’), those realized [LH] (e.g. běy ‘sago’), and those realized [L] (e.g. gèy ‘areca nut’). For the purposes of this presentation, monosyllables realized [H] are analyzed as High, those realized [LH] are realized as Rise (LH), and those realized [L] are analyzed as toneless. So far, 62 monosyllabic cognates have been identified between the two dialects. These monosyllables can be sorted into five different correspondence sets, which will be referred to as sets A-E. Examples of each of the five correspondence sets are given in Table 1. The proto-Ambel reconstructions are also provided.

We apply a panel vector autoregression model to a firm-level longitudinal database to observe the co-evolution of sales growth, employment growth, profits growth and growth of R&D expenditure. Contrary to expectations, profit growth seems to have little detectable effect on R&D investment. Instead, firms appear to increase their total R&D expenditure following growth in sales and growth of employment. In a sense, firms behave ‘as if’ they aim for a roughly constant ratio of R&D to employment (or sales). We observe heterogeneous effects for growing or shrinking firms however, suggesting that firms are less willing to reduce their R&D levels following a negative growth shock than they are willing to increase R&D after a positive shock.

The CER 3 wax biosynthetic gene from Arabidopsis thaliana is allelic to WAX 2 / YRE / FLP 1

The cuticle coats the aerial organs of land plants and is composed of a cutin matrix embedded and overlayed with waxes. The Arabidopsis CER3 gene is important for cuticular wax biosynthesis and was reported to correspond to At5g02310 encoding an E3 ubiquitin ligase. Here, we demonstrate that CER3 is not At5g02310 and instead corresponds to WAX2/ YRE/FLP1 (At5g57800), a gene of unknown function required for wax biosynthesis. CER3 protein has also been implicated in cutin production because strong cer3 alleles display organ fusions. Leaf cutin analysis of two cer3 alleles did not reveal significant differences in cutin load or composition, indicating that CER3 has no major role in leaf cutin formation. 2007 Federation of European Biochemical Societies.

LAVANDULA HYBRIDA : MICROSCOPIC CHARACTERIZATION AND THE EVALUATION OF THE ESSENTIAL OIL

Lavandin (Lavandula hybrida Reverchon) is related to Lavandula angustifolia, but the species cultivated in Romania are poorly studied in terms of their secondary metabolites and their uses in therapy. The purpose of the study was mainly to reveal the microscopic characteristics of Romanian lavandin grown in Piatra Neamț, Romania. Moreover, the biological potential of volatile fractions isolated from lavender (used for comparison) and lavandin were assessed especially on standard microorganisms. The results indicated similar microscopic elements, and some common chemical characteristics to Lavandula angustifolia, but also an important variation regarding the antimicrobial activity of the essential oils.
Exploring the Problems, Issues and Challenges of E-government in Kiribati

ABSTRACT:The use of e-government to deliver public service is a recent phenomenon for the small island developing states (SIDS). This paper uses the Contingency approach to explore e-government in Kiribati. The Contingency approach is chosen for his paper on the grounds that it is able to adequately explain the 'situational factors' that affect the provision and delivery of e-government services in the context of Kiribati. Some of the situational factors present in the small island developing states that affect the provision and delivery of e-government services are poor infrastructure environment, technological environment, political environment, socio-economic conditions and dispersed geographical environment. The findings from this study showed that some of the problems, issues and challenges of e-government in Kiribati are poor internet connectivity, poor infrastructure environment, technical problems in developing and maintaining e-government website, low level of computer literacy rate, low level of computer and internet access, cultural issues and digital divide, lack of awareness on e-government services, privacy and trust issues, and language problems on the e-government website. Some of the ways how these problems can be addressed are development of infrastructure environment, training and development of staff, integrating e-government dynamics in the school curriculum, financial support, improving the e-government website and increasing awareness on e-government service.
Investigation of Excess Sludge Generated from Activated Sludge Treatment Plant of Concentrated Latex Factories: An Investigative Case Study in Southern Thailand

Activated sludge technology has been employed for wastewater treatment in the concentrated latex factories in the south of Thailand. This paper highlights the survey results of the excess sludge generated from activated sludge treatment plants of the concentrated latex factories, including sludge generation rate, sludge characteristics, as well as sludge management and its problems. The total number of 11 factories was investigated. The findings showed that 20% of the investigated factories using activated sludge did not know how much the excess sludge generation rate was. With an in-depth investigation, the excess sludge generation rate was determined as for 28 kg/ton concentrated latex product or 10 kg/ton of field latex used in the concentrated latex factories. The excess sludge had a low C/N ratio with an average value of 4.7 and contained N, P, and K with the average of percentage values of 8.0, 2.0, and 1.0% dry basis, respectively. However, the excess sludge consisted of Zn with an average of 3.01% dry basis. 60% of the investigated factories using an activated sludge system had issues concerning the management of excess sludge. Moreover, various aspects of the excess sludge management were discussed and lessons were learned on the current excess sludge management of the concentrated latex industry in the south of Thailand.
Effect ofTGF-pt on Re-Epithelialization ofHum . an Keratinocytes In Vitro : An Organotypic Model

Transforming growth factor beta-t (TGF-ftt) has been shown to inhibit keratinocyte proliferation in vitro yet to stimulate wound healing in vivo. To explore this apparent paradox, the effect of TGF-fit on proliferation and migration was investigated in organotypic cultures after incisional wounding. Organotypic cultures provide a more in vivo -like epidermal tissue and may therefore respond in a different manner than previous culture models in which epidermal differentiation is incomplete. Without TGF-ftt, keratinocytes were hyperproliferative in response to wounding. At doses of2.5 ngjmlor greater, a delay in re-epithelialization was seen at 24 h post-wounding along with a reduction in hyperpro-
Measuring the effects of two different simulation settings on participants in emergency medicine scenarios

Background: Simulation training is now widely used in medical education. Traditionally, simulation courses take place in simulation centers where considerable effort is done to mimic a real working environment. In-Situ simulation provides simulation in a real working environment, where highly realistic training conditions can be provided. This study looks especially into the question whether or not the simulation environment in in-situ simulations changes the student’s perception of realism of the scenario and evaluates if perceived realism correlates to the students statement on how relevant the scenario was for achieving the learning objectives. Methods: This observational study compares two groups of healthcare professionals (n = 25) who participated at an one-day course on emergency medicine. For both groups, a medium-fidelity simulator and authentic medical equipment was used to simulate complex emergency medicine scenarios. For the study group, an In-Situ setting was chosen in a mobile intensive care unit (MICU), whereas the control group did the scenarios in a conference room. A participant response tool was used to measure student’s perception of realism based on three dimensions of realism. 5-point Likertscales (5=fully agree, 1= fully disagree) where used to measure immersion and relevance from students perspective. Results: There were significant differences in the level of perceived physical realism between the two groups, efforts done to increase the level of realism in In-Situ simulation were perceived by the students (4.48 vs 4.11, P<0.05). Simulation settings, however, did not influence the perception of both semantic and phenomenal realism significantly (4.33 vs. 4.44, 4.22 vs. 4.43 respectively). In general, those students with higher levels of perceived realism rated the scenarios as more relevant for their professional life, realism indices correlate well with relevance indices using the Pearson correlation (P=0.008). Conclusions: In-Situ Simulation alters the level of perceived physical realism, but not the level of perceived relevance in general. However, results of this study suggest that factors including scenario design help to reach high levels of perceived realism, especially in its phenomenal and semantic dimension. Perceived realism in general increases the relevance of the simulation scenario for the learner.
