Abstract:
Organizing function is the significant component of management guaranteeing the success of construction works. Many studies have been emphasizing on the topic of critical success factors (CSFs) within construction works, yet the results have rarely emphasized examining organizing behaviors within public construction work management; these less researched topics were the aims of this study. To fulfil this research aim, a regression analysis design was employed. Data were collected using questionnaires conducted from 139 professionals involved in public construction works management in Vietnam. The structural equation modelling (SEM) technique with partial least-squares estimation (PLS) was utilized to analyze the data. The results revealed 6 behavioral dimensions (i.e., structure organizing (OR1), authorization organizing (OR2), coordination organizing (OR4), human resource organizing (OR3), job organizing (OR5), responsibility organizing (OR6) to assess organizing function in terms of public construction work management. The study also reveals that structure organizing (OR1), authorization organizing (OR2), coordination organizing (OR4) have significant effects on management effectiveness (ME). In addition, coordination organizing (OR4) acts as the mediator of Human resource organizing (OR3), job organizing (OR5); while responsibility organizing (OR6) indicates an indirect influence through the mediator of OR5. The success of this approach is expected to reinforce the contribution of organizing function and suggest a useful tool for supporting the professionals in enhancing public construction work management.

Abstract:
This study aimed to replicate, for the first time on Serbian population, the own-race bias (ORB), a classical effect from the face perception domain. The ORB was additionally contrasted with familiarity and the own-gender bias (OGB). Recognition accuracy for own race faces was higher in comparison both to African (Z=3.29, p<0.01) and Asian faces (Z= 2.59, p<0.01). The introduction of famous faces led to a significant drop in the ORB. However, in all of the conditions a ?seen before? effect was measured, suggesting better recognition for own race faces, independent of familiarity. The OGB was obtained for own-race faces (?2(28, 7) = 119, 34 p <0, 05), while there were no differences in recognition accuracy between the own and the other-race faces of the other gender. These results imply that the ORB could be explained, at least partially, by the OGB. However, these results were obtained on an exclusively female sample.

Abstract:
Based on investigation of rural buildings in china, there are more than 20% of the masonry structures constructed in 1970s. Thus, the old blue bricks (OBB) and old red bricks (ORB), which demolished from the typical brick masonry structures was built in 1970s, was chosen in the test. During demolishing the OBB and ORB, the original mortar was destroyed. Thus, the 1:7.8 cement mortar was chosen instead of original mortars and the 1:5 cement mortar was chosen as the reinforcement mortar. In order to know the performant of the reinforcement methods, there are three-level test plan was put forward in the study. Firstly, the mechanical properties of OBB and ORB and mortars was tested; Secondly, the experiment tested the shear strength of the reinforced and unreinforced masonry specimens along mortar joints; Thirdly, there are four walls (OBB reinforced wall and unreinforced wall, ORB reinforced wall and unreinforced wall) have been made for the pseudo-static tests. This research conducted physical performance tests on masonry bricks, masonry components, and masonry walls of typical masonry structures. Through experiments, the shear capacity of the masonry structure reinforced by high-strength mortar and steel bars can be obtained.

Abstract:
Purpose – Within controlled environments such as prisons or forensic facilities, strong sanctions and other factors can inhibit the expression of offence-linked behaviours otherwise observable in community settings. For example, institutional restrictions may distort the offender’s habitual expression of aggressive behaviours such that the individual’s aggressive characteristics are less intense or observable. Thus, the influences of controlled settings can make it difficult for staff to capture idiosyncratic evidence of change or lack thereof over time or with treatment. The purpose of this paper is to describe an assessment and measurement framework that can be used to assist treatment and correctional staff collectively focus attention on relevant characteristics and behaviours idiosyncratically linked to offending. Design/methodology/approach – The authors use the terms “offence analogue behaviours (OAB)” to describe proxies of offence behaviours observable in controlled settings and “offence replacement behaviours (ORB)” as the contrasting positive, pro-social skills and strategies that the individual implements to change and manage problem areas linked to aggression and criminality. This paper discusses the application and practical utility of the framework and an associated assessment and measurement tool; the Offence Analogue and Offence Replacement Behaviour Guide (Gordon and Wong, 2009-2013). Findings – The OAB and ORB Guide has shown to be useful by directing the attention of treatment personnel to the here-and-now offence related behaviours displayed by offenders in custodial settings. In the absence of such focused attention, relevant proxy behaviours can often be masked in these highly controlled environments. The Guide is therefore a useful adjunct to identify such behaviours for treatment and for assessing treatment-related changes. Research limitations/implications – The OAB/ORB Guide was developed based on a conceptual framework derived from the empirical literature on correctional treatment, risk assessment, psychological theories and clinical practice. While there has been some positive pilot use of the Guide’s utility and preliminary research, at this point, empirical evidence is still lacking. Practical implications – The OAB/ORB Guide provides quantified and structured guidelines to assess offence proxy and offence replacement behaviours observable day-to-day within controlled environments, such as during custody or supervised release to the community. Originality/value – This guide was developed to assist staff with the identification, documentation and measurement of idiosyncratic negative and positive offence-related proxy behaviours observable across custodial or supervised contexts. Accordingly, the authors suggest that OAB/ORB guide information can be used to evaluate changes in risk over treatment and/or time. Further, the authors describe how this framework may enhance the efficacy of multi-disciplinary treatment and management teams. Two cases are used to illustrate the application of the Guide.

Abstract:
Abstract Background Injured oil workers are exposed to a broad microbiome in hydraulic fracturing fluids (HFF) and oil wells at the time of injury. This includes Pseudomonas, Stenotrophomonas, Acinetobacter, and rare human pathogens which may be harder to culture. This study evaluates oil-related burn (ORB) microbiology. Methods Patients admitted to the USAISR burn center enrolled in the Epidemiology of Workplace Burns and Injuries in Texas registry from April 2011 to November 2016 were included as cases and controls. Patients hospitalized ≤2 days were excluded. ORB was defined as exposure to HFF (FORB), or non-HFF (NFORB). Controls were patients admitted with industrial burns (non-ORB). Patient demographics and clinical cultures (days 1–15) were obtained through the registry and electronic medical record. Results 149 industrial burns were included, of which 35 (23%) were ORB and 114 (77%) were non-ORB. Of the ORB, 11 (31%) were FORB and 24 (69%) were NFORB. ORB had a median age, TBSA, and Baux score of 31, 25, and 58 compared with non-ORB with 36, 4, and 44, respectively (P &lt; 0.01). Twenty-five patients had positive cultures: 12 (48%) non-ORB and 13 (52%) ORB. Sixty Isolates identified from the ORB population included Flavobacterium, Pseudomonas, and Serratia. FORB accounted for three (25%) of the culture positive ORB. S. marcescens was isolated in 1 FORB (33%) compared with 0 NFORB and non-ORB (P &lt; 0.05). Otherwise, there was no statistical difference in isolates. Median time to first positive culture differed among non-ORB (4 days), FORB (13 days), and NFORB (3.5 days, P = 0.03). Forty-six (31%) patients had cultures obtained during admission: three (7%) FORB, 12 (26%) NFORB, and 31 (67%) non-ORB. Of cultured patients, ORB had a median TBSA and Baux score of 44 and 90 compared with non-ORB with 11 and 47, respectively (P &lt; 0.01). Comparing all cultured patients, ORB had more positive, negative, and total cultures compared with non-ORB with 2 vs. 0, 7 vs. 3, and 10 vs. 3, respectively (P &lt; 0.01). Conclusion Within this cohort, ORB was associated with more severe injuries compared with non-ORB. They had more positive, negative, and total cultures, and recovery of S. marcescens was associated with FORB. Larger studies with non-culture based technology could help further define the microbiology of this uniquely exposed population. Disclosures All authors: No reported disclosures.

Abstract:
The RRM-type RNA binding protein Orb plays a central role in the establishment of polarity in the Drosophila egg and embryo. In addition to its role in the formation and initial differentiation of the egg chamber, orb is required later in oogenesis for the determination of the dorsoventral (DV) and anteroposterior (AP) axes. In DV axis formation, Orb protein is required to localize and translate gurken mRNA at the dorsoanterior part of the oocyte. In AP axis formation, Orb is required for the translation of oskar mRNA. In each case, Orb protein is already localized at the appropriate sites within the oocyte before the arrival of the mRNAs encoding axis determinants. We present evidence that an autoregulatory mechanism is responsible for directing the on site accumulation of Orb protein in the Drosophila oocyte. This orb autoregulatory activity ensures the accumulation of high levels of Orb protein at sites in the oocyte that contain localized orb message.

Abstract:
orb encodes one of the two fly CPEB proteins. These widely conserved proteins bind to the 3′UTRs of target messenger RNAs (mRNAs) and activate or repress their translation. We show here that a positive autoregulatory loop driven by the orb gene propels the specification of oocyte identity in Drosophila egg chambers. Oocyte fate specification is mediated by a 3′UTR-dependent mechanism that concentrates orb mRNAs and proteins in one of the two pro-oocytes in the 16-cell germline cyst. When the orb 3′UTR is deleted, orb mRNA and protein fail to localize and all 16 cells become nurse cells. In wild type, the oocyte is specified when orb and other gene products concentrate in a single cell in region 2b of the germarium. A partially functional orb 3′UTR replacement delays oocyte specification until the egg chambers reach stage 2 of oogenesis. Before this point, orb mRNA and protein are unlocalized, as are other markers of oocyte identity, and the oocyte is not specified. After stage 2, ∼50% of the chambers successfully localize orb in a single cell, and this cell assumes oocyte identity. In the remaining chambers, the orb autoregulatory loop is not activated and no oocyte is formed. Finally, maintenance of oocyte identity requires continuous orb activity.

Abstract:
Allteftersom forskningen inom Human Computer interaction (HCI) fortskrider konstrueras det allt fler innovativa sätt att interagera med spelkonsoller. Då fler sätt att interagera med spelkonsoller utvecklas förbättras även förutsättningarna för spelbranschen att öka interaktionen i spelen. Den senaste generationen av spelkonsoller har kommit fram med egna lösningar och innovativa sätt att öka spelupplevelsen och interaktionen. Nintendo Wii har t.ex. en rörelsesensor som reagerar på rörelserna av handkontrollen, och Xbox Kinect reagerar med hjälp av en kamera som läser av kroppens rörelser och Playstation Move reagerar på en kombination av en kamera och en kontroll med sensorer. Handkontrollens design har inte förändrats mycket under de senaste konsol-generationerna om man bortser från Nintendo Wii som formade sin kontroll som en stav. Kontrollen har haft en bumerangform, som med tiden har fått fler knappar och i senare generationer analoga spakar. Kontrollen ligger bra i handen och designen ger en bra spelupplevelse i vissa genrer av spel. I vissa spel ökas interaktionen med tillbehör, som t.ex. musikinstrument för karaokespel som underlättar för spelaren. Undantaget är FPS-genren, där precisionen kompenseras med hjälp av mjukvara. Frågeställningen i denna avhandling är om man med hjälp av en ny handkontrollsdesign i formen av en sfär kan öka precisionen i FPS-spel. Designen avviker från den traditionella, och i kontrollen används modern teknologi för att kunna registrera lutningar av handkontrollen. Med hjälp av intervjuer kan jag utvisa huruvida kontrollen förbättrar precisionen och spelkänslan, och vilka områden som behövs förbättras. Slutsatsen blev att testerna inte var tillräckliga för att rättvist kunna säga om det misslyckades eller lyckades då respondenterna som var missnöjda med känsligheten trots allt gillade styrningen.

Abstract:
"The use of cameras and computer vision algorithms to provide state estimation for robotic systems has become increasingly popular, particularly for small mobile robots and unmanned aerial vehicles (UAVs). These algorithms extract information from the camera images and perform simultaneous localization and mapping (SLAM) to provide state estimation for path planning, obstacle avoidance, or 3D reconstruction of the environment. High resolution cameras have become inexpensive and are a lightweight and smaller alternative to laser scanners. UAVs often have monocular camera or stereo camera setups since payload and size impose the greatest restrictions on their flight time and maneuverability. This thesis explores ORB-SLAM, a popular Visual SLAM method that is appropriate for UAVs. Visual SLAM is computationally expensive and normally offloaded to computers in research environments. However, large UAVs with greater payload capacity may carry the necessary hardware for performing the algorithms. The inclusion of general-purpose GPUs on many of the newer single board computers allows for the potential of GPU-accelerated computation within a small board profile. For this reason, an NVidia Jetson board containing an NVidia Pascal GPU was used. CUDA, NVidia’s parallel computing platform, was used to accelerate monocular ORB-SLAM, achieving onboard Visual SLAM on a small UAV. Committee members:"

Abstract:
An object recognition system called ORB1 is proposed and implemented for use on a mobile robot. ORB utilizes the QUADRIS sensor platform developed at the Centre for Intelligent Machines (CIM) at McGill University, which is composed of two BIRIS2 laser rangefinders. ORB performs a series of sensory and perceptual tasks in conjunction with a mobile robot control architecture called SPOTT. ORB's main task is to sense the mobile robot's surroundings and provide laser range data, in the form of line segments, for SPOTT's map database. In an office environment, ORB also identifies and labels the structural objects (i.e., walls, doors) in this map. While navigating through an office space, the mobile robot may be required to search for certain objects in the area. In these scenarios, ORB is used to recognize the movable objects (i.e., chairs, tables and desks).
ORB is able to perform its tasks in a fast and efficient manner by using simple models to represent the structural and movable objects in its database. ORB's recognition procedures only require sparse sets of range scans to identify the aforementioned objects. The structural object models are built from prior knowledge of the office environment. For example, the doorway model would consist of the known doorway widths found on the experimental office floor. ORB has been tested extensively in the CIM environment, but it can also be applied to any office space provided the structural dimensions are known a priori. ORB's models for the movable objects are idealized descriptions with the object's surfaces represented by planes. The physical dimensions of the movable object models are defined by Architectural Standards, as office furniture are built to conform to these standards.

Among a myriad of spider web geometries, the orb web presents a fascinating, exquisite example in architecture and evolution. Its structural component, the silk protein, is an exemplary natural material because its superior properties stem intrinsically from the synergistic cooperativity of hierarchically-organized components, rather than from the particular properties of the building blocks themselves. By bridging together different levels of hierarchy in the web, we elucidate the mechanisms by which structure at each composite level contributes to organization and material phenomena at subsequent levels, demonstrating that the web is a highly adapted system where both material and hierarchical structure across all length-scales is critical for its functional properties. Further, the material hierarchy scheme within the orb web is exploited to address questions of silk evolution. Spider orb webs can be divided into two categories distinguished by the capture silk used in construction: cribellate orb webs composed of pseudoflagelliform silk coated with dry cribellate threads and ecribellate orb webs, composed of viscid flagelliform silk fibers, coated by adhesive glue droplets. Cribellate capture silk is generally stronger but less extensible than viscid capture silk and a body of phylogenic evidence suggests that cribellate capture silk is more closely related to the ancestral form of capture spiral silk. Here, we use a coarse-grained web model to investigate how the mechanical properties of spiral capture silk affect the behavior of the web system, illustrating that more extensible capture spiral silk yields a decrease in the web's energy absorption, suggesting that the function of the capture spiral shifted from prey capture to other structural roles. Additionally, we observe that in webs with more extensible capture silk, the effect of thread strength on web performance is reduced, indicating that thread extensibility is a dominant driving factor in web diversification. In this thesis, we propose a novel model-centered materials-hierarchy based approach to studying evolutionary trends and suggest possible applications for other fields.

The Araneidae Clerck, 1757 has 3029 species in 168 genera. They are common in nature, weaving orbicular bidimensional webs on trees and bushes and, apparently, have nocturnal habits. Spiders of Eustala Simon, 1895 occur throughout all American continent and it seems to be the most speciose Neotropical Araneidae genus. The genus contains about 90 species, 16 of which have been described from Brazil. The male is characterized by the palpus with only one patellar macroseta; conic, whitish hanging down posteriorly median apophysis and the terminal apophysis is a sclerotinized extension, resting on a transparent, baloon-like, subterminal apophysis. The females are characterized by the epigynum with ringed scape pointed anteriorly. The most common pattern color on the abdomen dorsum is a folium. However, this could vary from specimen to specimen, being more or less pigmented. Although frequently collected, species of this genus are poorly known, at present, there are just a few studies on the genus from South America. Thus this study aims to contribute to the knowledge of the Brazilian species of Eustala, through diagnosis and illustrations of species from Southern Brazil, giving continuity to the work initiated about the genus on Rio Grande do Sul state. In order to carry out this study, Eustala material from several arachnological collections was analyzed. Illustrations were made with the aid of camera lucida coupled to the stereoscopic microscope. The left male palpus was illustrated on mesal and ventral views; the epigynum was illustrated on ventral, posterior and lateral views. In current study Eustala ulecebrosa (Keyserling, 1892), from Rio Grande do Sul and E. mourei Mello-Leitão, 1947, from Paraná are illustrated and redescribed. Eight new species from Southern Brazil are described: E. guarani sp. nov., from Paraná; E. catarina sp. nov., from Santa Catarina and E. ericae sp. nov., E. cidae sp. nov., E. lisei sp. nov., E. cuia sp. nov. and E. farroupilha sp. nov, all based on males and females and E. eldorado sp. nov., based only on males, from Rio Grande do Sul. Eustala albiventer (Keyserling, 1884), E. taquara (Keyserling, 1892), E. minuscula (Keyserling, 1892), E. itapocuensis Strand, 1916, E. photographica Mello-Leitão, 1944, E. levii and E. palmares, Poeta, Marques & Buckup, 2010 present new distribution records from Brazil and E. perfida Mello-Leitão, 1947 has a first record in Uruguay.
A família Araneidae Clerck, 1757 agrega 3029 espécies em 168 gêneros. Aranhas comuns na natureza, tecem teias orbiculares bidimensionais na vegetação arbustiva e arbórea e, aparentemente, têm hábitos noturnos. Eustala Simon, 1895 ocorre em todo o continente Americano e parece ser o gênero Neotropical de Araneidae com maior riqueza de espécies. O gênero contém cerca de 90 espécies, das quais 16 são descritas do Brasil. O macho caracteriza-se pelo palpo com única macrocerda patelar, apófise média cônica e esbranquiçada, voltada posteriormente e pela apófise terminal que é um prolongamento esclerotinizado sobre a apófise subterminal, em forma de balão transparente. As fêmeas se caracterizam pelo epígino com escapo dirigido anteriormente, podendo ser liso ou anelado. O padrão de colorido frequente no dorso do abdômen é o fólio, no entanto, muitos espécimes variam na coloração, podendo ser mais ou menos pigmentados. Apesar de frequentemente colecionadas as espécies desse gênero são pouco conhecidas, visto que são escassos os trabalhos taxonômicos do gênero para a América do Sul. Assim, este estudo visa contribuir para o conhecimento das espécies brasileiras de Eustala, através da diagnose e ilustração das espécies dos estados da região Sul do Brasil, dando continuidade ao trabalho iniciado sobre o gênero no estado do Rio Grande do Sul. Para a execução deste projeto, o material de Eustala depositado nas coleções aracnológicas das regiões Sudeste e Sul do Brasil foram examinados. As ilustrações foram realizadas com o auxílio de câmara-clara acoplada ao microscópio estereoscópio. O palpo esquerdo foi ilustrado nas vistas ventral e mesial e o epígino nas vistas ventral, posterior e lateral. No presente trabalho são redescritas Eustala ulecebrosa (Keyserling, 1892), do Rio Grande do Sul e E. mourei Mello-Leitão, 1947, do Paraná. Oito novas espécies são descritas do Sul do Brasil: E. guarani sp. nov., do Paraná; E. catarina sp. nov., de Santa Catarina e E. ericae sp. nov., E. cidae sp. nov., E. lisei sp. nov., E. cuia sp. nov. e E. farroupilha sp. nov., todas baseadas em machos e fêmeas, e E. eldorado sp. nov., baseada em exemplar macho, do Rio Grande do Sul.

Abstract:
Circadian clocks enable coordination of essential biological and metabolic processes in relation to the 24-hour light cycle. However, there are many habitats that are not subject to this light cycle, such as the deep sea, arctic regions, and cave systems. This study analyzes the circadian pattern of isolated populations of a subterranean spider, Meta ovalis from two Tennessee caves and five Indiana caves. Locomotor activity was recorded with TriKinetics LAM50 Locomotor Activity Monitor under a 12-hour light (L), 12-hour dark (D) (LD 12:12) cycle preceding total darkness (DD). Significant differences were found within and among populations found in Tennessee cave systems in average free running period and onset of locomotor activity. Selection, drift, and genetic fixation are explored as the causes of variation in the present study, using M. ovalis as the model organism. All five caves in Indiana show little variation, whereas both Tennessee caves show large interindividual variation.

Abstract:
Circadian clocks are endogenous time keeping mechanisms that are ubiquitous among animals. They enable coordination of many essential biological and metabolic processes in relation to the 24 hour light cycle on earth. However, there are many habitats on earth that are not subject to this light cycle. This study aims to look at the potential genetic drift of the circadian rhythm of a subterranean spider, Meta ovalis, as well as gathering general natural history information on this under-studied spider. This study will fill general gaps in knowledge of this spider and its habitat, highlight the importance of studying organisms within a subterranean environment, and place importance on cave conservation and acquiring knowledge of these specialized, and sensitive species. This study integrates circadian and foraging theory to evaluate species as circadian specialists and generalists based on how narrowly or widely their activity is spread over the 24 h cycle. We suggest that M. ovalis benefits from a generalist strategy, showing small bursts of focused activity widely dispersed across the 24 h cycle, allowing it to capture prey opportunistically whenever it is available. Live spiders were collected from area caves, monitored in an environment controlled for light and temperature, and returned to their cave of origin. The activity of each spider was analyzed for differences in circadian activity among and between populations to determine if there is a significant drift of the circadian strategy between isolated populations of Meta ovalis. We expect to see a different circadian strategy implemented between populations due to drift from the spiders being isolated from other populations.

Abstract:
This thesis investigates the problem of tracking objects for an Augmented Reality (AR) setting. More specifically, the issue of tracking Post-It® notes to be used in a Mobile Augmented Reality (MAR) application using the Oriented FAST and Rotated BRIEF (ORB) keypoint extractor and descriptor, is investigated. This problem explores the relatively new and unexplored territory of tracking specific objects in real-time on mobile devices. Since MAR is becoming more prevalent, this is a field that is likely to be explored in more depth in the future. A solution was implemented in an existing note scanning application. Test sequences, with accompanying ground truth, were created for the applicable scenarios. The test sequences were used to reliably verify and evaluate the implementation with regard to precision, recall, accuracy, and speed. The ground truth was generated in a Mixed-Initiative Computing (MIC) application. The results show that tracking using only ORB is not viable if high precision, recall, or accuracy is needed. While tracking via ORB may not be viable as a standalone solution, the thesis describes methods for using it in a MIC setting, which may be viable.
Denna masteruppsats undersöker spårning av objekt för användning i en AR- miljö. Mer specifikt så undersöks spårning av Post-It®-notiser för användning i en MAR applikation med hjälp av ORB. Det här problemet utforskar det relativt nya och outforksade området rörande spårning av specifika objekt i realtid på mobila enheter. Eftersom MAR blir alltmer vanligt förekommande, så kommer det här forskningsområdet troligtvis att utforskas mer ingående i framtiden. En lösning implementeras utöver en existerande applikation for att skanna notiser. Testsekvenser, med ackompanjerande faktisk data skapades för de relevanta scenarierna. Dessa testsekvenser användes för att kunna verifiera och utvärdera implementationen med avseende på precision, återkall, träffsäkerhet och snabbhet. All faktisk data genererades i en MIC-applikation. Resultaten visar att spårning med enbart ORB är inte genomförbart om höga krav på precision, återkall, träffsäkerhet eller snabbhet behövs. Medan spårning via ORB måhända inte är genomförbart i nuläget som en självstående lösning, så har den här mastersuppsatsen beskrivit metoder för att använda ORB i en MIC-applikation. Något som faktiskt kan vara genomförbart.
