Abstract:
Abstract We present observations of 23 Starlink satellites in the g′ bandpass, obtained from the Dominion Astrophysical Observatory’s Plaskett 1.8 m telescope. The targets include a mixture of satellites with and without brightness mitigation measures (i.e., visors). At the time of the observations (2021 July 16), Starlink satellites were sunlit throughout the night, and, even with strict elevation and azimuth limits, there were over 800 candidate Starlink arcs. The satellites altogether have a median range corrected brightness (550 km) of H ¯ g 550 = 5.3 mag. Dividing the targets into those without and with visors, their median range corrected magnitudes are H ¯ g 550 ( no visor ) = 5.1 and H ¯ g 550 ( visor ) = 5.7 mag, respectively. While the visor sample is dimmer in aggregate, the range corrected brightness distribution ranged from H g 550 = 4.3 mag to 9.4 mag. The two brightest satellites have similar H g 550 to within the uncertainty, but one is visored and the other nonvisored. The dimmest satellite we observed is one without mitigations. The intrinsic brightness dispersion among the full sample is σ g = 0.5 mag.

Abstract:
The need to protect aircrews from ocular laser exposures increases as lasers proliferate in military systems. Many aircraft lighting incompatibilities are associated with the current Air Force daytime laser eye protection (LEP) visor. Weapons Systems Trainer (WST) and ground tests were conducted to determine the compatibility of three prototype LEP visors with F-15E aircraft lighting. In the WST, aircrews rated statements concerning the visibility and color appearance of the instruments with the LEP. For ground tests, F-15E instructors viewed lights inside and outside of the cockpit with the LEP before and after sorties and completed questionnaires about their visibility. The visibility of most of the F-15E instruments was not detrimentally affected by LEP use, but their color appearance was altered, which affected the utility of two head-down displays (HDDs). One LEP visor also affected exterior aircraft lighting visibility. The majority of the aircrews judged the LEP visors to be safe for F-15E flight operations.

Abstract:
The purpose of this investigation was to determine the effects of varying facemask reinforcement and visor tint on peripheral visuomotor abilities in collegiate football players. Division I NCAA football players (n = 14) completed two peripheral visuomotor experiments: (1) Varying facemask reinforcement, (2) Varying visor tinting. In experiment 1, participants were tested under the following conditions: baseline (no helmet; BL), helmet + light (HL), helmet + medium (HM), helmet + heavy (HH), and helmet + extra heavy (HXH) reinforced facemasks. In experiment 2, participants were tested under the following conditions: baseline (no helmet; BL), helmet only (HO), helmet + clear (HCV), helmet + smoke-tinted (HSV), and helmet + mirror-tinted (HMV) visors. For each condition, a 60 s peripheral visuomotor test was completed on a Dynavision D2 visuomotor board. For experiment 1, the BL peripheral reaction time (PRT) was faster than all facemask conditions (p < 0.05). Furthermore, PRT was impaired with the HXH compared to HL (p < 0.001), HM (p < 0.001), and HH (p = 0.001). Both HH and HXH resulted in the potentiation of PRT impairments in the outermost and inferior peripheral visual areas (p < 0.05). In experiment 2, BL PRT was faster than all helmeted conditions (p < 0.05). Additionally, PRT was slower in HSV (p = 0.013) and HMV (p < 0.001) conditions compared to HO. HMV resulted in slower PRT in all peripheral areas (p < 0.05) while PRT was impaired only in outer areas for HSV (p < 0.05). Wearing protective football headgear impairs peripheral visuomotor ability. Lighter reinforced facemasks and clear visors do not appear to exacerbate impairment. However, heavier reinforced facemasks and tinted visors further decrease visuomotor performance in outer and inferior visual areas, indicating a potential need for considerations of on-field player performance and safety.

Abstract:
Aerodynamic drag is one of the most important sources of the driving resistance suffered by an on-road heavy-duty truck. The previous studies have rarely involved the role of the external sun visor. Therefore, numerical method is used for the research of the influence of six kinds of sun visors differenced by shapes or layouts on the aerodynamic drag reduction. It is demonstrated that the sun visor has a great influence on the local flow field where it is fixed, while a relatively small effect on the global flow field. Moreover, compared to the original one, the CDvalues of each case have different degrees of reduction which illustrates that an appropriate shape and layout of a sun visor benefits the air drag reduction, the largest decline is 4.7%.

Abstract:
Three subjects were used to compare superior visual-field threshold for 5 North American industry-standard opaque safety hard hats with a prototype clear translucent-visor safety hard hat and a no-hat baseline condition. Average maximum degrees of superior visual field was equivalent for the clear-visor safety hat and no-hat conditions (52.0° versus 48.3°) but the opaque-visor safety hats resulted in only 15.1°. The opaque safety hats were worse than the clear-visor safety hat and no-hat conditions by, on the average, an order of 3. Analysis indicated that visual-field obstruction is a potential problem for wearers of opaque safety hats. Field research will be required to assess the extent of injuries caused by an impaired superior field of vision when wearing opaque-safety-hat visors. The potential positive effects of the clear-visor safety hat on reduction of accidents also must be determined.

Abstract:
The objective of the investigation is to establish the effect of the protection measures established by the government to reduce the contagion by Covid -19 in the district of Barranca during the second wave of infections. Data were collected on compliance with protection measures such as distancing, use of masks, visors and disinfection with alcohol in public places such as streets, markets, banks and parks. For this, data collection instruments based on visual inspection were used to verify the appropriate use of protection measures, as well as a survey regarding the use of alcohol as a disinfectant; and the data obtained was processed through basic statistics and correlation with the data reported by the Ministry of Health of positive infections by Covid-19. It was determined that there is a growth relationship between compliance with protection measures and the number of positive infections, with correlation coefficients for distance of 0.7458, use of 0.6710 masks, 0.8784 visors and use of alcohol as a disinfectant of 0.7310. Regarding the analysis of variance, it is obtained that the use of visors influences the number of positive infections, which is why it is concluded that maintaining distance, in addition to the use of masks and disinfectant alcohol are effective measures to control the number of infections per coronavirus.

Abstract:
Prior studies on museum visitors are extensively centred on national museums, the studies on regional museums are scarce. To fill in the academic gap, a research is proposed concerning the visitors of Dalarna Museum, a regional museum in Sweden. With an aim to profile visitors’ demographic characteristics and investigate the motivational factors that influence visitors’ frequency of visits, a face-to-face questionnaire survey was implemented at Dalarna Museum. To get visitors’ demographic characteristics, a few closed and open questions are devised to profile visitors’ gender, age, occupation, income, education, number of children and residence place. To investigate the motivational factors that influence visitors’ frequency of visits, a seven-point Likert questionnaire is employed with 17 motivational factors included. During a 12-day data collection, 372 visitors were invited to participate in the questionnaire survey, whereof 357 had filled in the questionnaire, generating a response rate that is as high as 96 percent. After data cleansing, there are 355 completed and valid responses in total. According to the results, some of visitors’ demographic characteristics are similar including gender, age, occupation, income, and number of children. However, the characteristics regarding visitors’ residence places and educational attainments are different comparing the frequent visitors to occasional visitors. Through running a multiple regression analysis, 13 out of the 17 motivational factors are detected having significant influences on visitors’ frequency of visits to Dalarna Museum, of which the most influential one is visitors’ day-outs with their friends and relatives.

Abstract:
The literature suggests that a correlation exists between visitor satisfaction and a visitor's choice to re-experience a product. The higher one's satisfaction level, the more likely he/she is to experience the product again and/or provide positive word-of-mouth advertising to friends and family. The Tian-Cole and Crompton model was chosen because of its acknowledgment and explanation of the differences between Visitor Satisfaction (VS) and Service Quality (SQ) and how their relationship influences satisfaction and contributes to Future Destination Selection. In addition to identifying a theoretical framework that explains why visitors return, it was necessary to identify a survey methodology to be used in developing the Mountain Pine Ridge Forest Reserve (MPRFR) visitor satisfaction surveys. It was determined that a combination of the Relative Performance Assessment (RPA) and Customer Service Questionnaire (CSQ) was an appropriate survey framework for a visitor satisfaction survey. As a result of the research, two visitor satisfaction surveys were developed: Intercept Survey and Mail-back Survey. The Intercept Survey will be administered at a MPRFR site. It was designed to be concise and not take much of the visitor's time. This survey will be used to gather general information about visitor characteristics and level of satisfaction while at a site. The Mail-back Survey will be sent to the visitor after their trip so more time can be devoted to answering a more detailed visitor satisfaction survey. This survey asks visitors to indicate what site characteristics are important to them and then rate their satisfaction with each item. Instruments from the report entitled "A Front Country Visitor Study for Grand Staircase-Escalante National Monument" were used as an example of how to format a visitor satisfaction survey and how to use the collected data as a managerial tool. The two main objectives of this research were accomplished and have established a foundation upon which subsequent research efforts will begin. This work serves as a catalyst to improving Belizean site planning, design, and management by better understanding what site characteristics contribute to visitor satisfaction.

Plews, Caroline Margaret Coatsworth. "Clients' reports of the work of health visitors in the child health clinic and during home visits." Thesis, University of Hull, 2001. http://hydra.hull.ac.uk/resources/hull:4626.

Full text
Abstract:
This study examines clients' reports of aspects of a single child health clinic visit and of a home visit by the health visitor. There are two foci of the thesis. First: recall; value and use of the advice/information selected by the client as the most important; second, an exploration of the meaning of support identified by some clients.Seven health visitors participated in the research, which incorporated two studies. In the first study, the researcher observed the content of discussions between 100 clients and the health visitor in child health clinics. These clients were then interviewed at home and asked questions about the advice/information received from the health visitor during theirprevious visit to the child health clinic.For the second study, information was recorded by the health visitor describing the content of 149 home visits. Clients were interviewed at home and asked similar questions regarding advice/information received from the health visitor. In addition, those clients who described receiving support were asked to describe the meaning to them of this aspectof the visit.Data analysis for both studies included descriptive and inferential statistics and content analysis.Findings from both studies indicate that recall of advice/information is related to the amount of advice/information given to the client. This may have implications for the amount of advice/information that health visitors are encouraged to provide.Advice/information received from the health visitor was generally valued and used by the mothers in both studies. Clients appeared most likely to be dissatisfied when topics had been raised which they had no interest in discussing. It is suggested that that there may be correspondence between some clients' descriptions of support, and taxonomies of social support found in social support literature. An exploration of health visiting work employing the concepts of social support is recommended.

Full text
Abstract:
This thesis approaches the study of the (aerial) military and non-military drone through an examination of the communities that variously compel and propel it into action: that culturally constitute it. Employing the term ‘proponent communities’, this thesis approaches the drone through an empiric-led exploration of such actors, those including: manufacturers, industry, regulators, governments, militaries, trade associations and end users. These proponent communities are accessed through fieldwork at three central sites, namely military and non-military tradeshows, military conferences, and through the completion of numerous industry educational courses. Whilst by no means a homogenous group, such communities remain important in crafting, composing, (re)producing and circulating both technical and cultural knowledges of the drone. In approaching the drone’s cultural constitution, the thesis pursues two distinct analytic foci. First, in response to the tendency of extant scholarship to focus upon what the functioning drone does and its implications, thus treating it like a ‘black box’, the thesis ‘opens’ the drone through an exploration of particular proponent cultures through which it is instituted. Examining both the role of military drone operators and the employment of drones with multi-sensory payloads in emergency service settings, over two chapters the thesis explores the cultures through which the drone comes to function in framing that below it. Second, the thesis explores a series of mechanisms through which the drone is articulated, visualized and otherwise legitimated as a tool, asset, and commodity within military and non-military drone tradeshows. In approaching the drone at the tradeshow, the thesis expands extant analyses of the drone by considering its cultural constitution at such hitherto unexamined sites of consumption. In approaching the cultural constitution of the drone through these two strands of investigation the thesis offers three contributions. First, in working within a research context punctuated with access limitations, the thesis opens up different windows of access at which drone proponent communities gather, form, and (re)compose drone knowledges. Second, in approaching the drone at sites in which it is instituted and traded, the thesis engages with both proponent knowledges of employment, and articulations of expectation and potential therein. It demonstrates that such an engagement facilitates the challenging of several dominant and entrenched narratives surrounding the drone, variously revealing them as inadequate, fractured, or fantastical. Third, whilst the main contribution of this thesis is to geographies, and the wider interdisciplinary field, of drone scholarship, the thesis argues for, and demonstrates the value of, engaging with alternative geographical literatures in developing its argumentation. In situating the drone within such wider discussions and landscapes the thesis thus productively develops distinct frameworks through which to conceptually and empirically engage with the drone.

Abstract:
The main purpose of the sun visor is to prevent the driver and passengers to get blinded by the sunlight. It is essential that the sun visor is not blocking the view and that the driver has a clear line of sight so that collisions can be prevented. However, the solution of today is limited as it only covers superior parts of the light and its functionality depends on the head position of the driver and passengers. Therefore, ÅF has initiated this thesis project to develop and improve the product with the goal to further prevent the driver and passengers from being blinded by the sunlight. The scope of the project is to generate new concepts for the sun visor using product development methods. The product development process involves various phases. Collecting and identifying customer needs and wishes resulted in a detailed requirement specification. Competitor analysis, or benchmarking, was conducted to create awareness of what already exists on the market. New concepts were created by two separate brainstorming sessions. These new concepts were evaluated by concept screening and concept scoring matrices and a final concept was chosen for further development. The final concept was modeled and developed with all necessary components in CAD with help of the software Catia V5. A material selection was performed on the new components with help of CES Edupack and a final material suggestion for each component was presented. The new sun visor consists of a sun curtain that is connected to profiles in the WEM cover and the a-pillar. An electric motor in combination with a spring regulates the upward and downward motion of the sun visor to a precise position. The driver or passenger can regulate the height of the sun curtain by pushing a button. An advantage with the new design is that it eliminates the leakage between the sun visor and the WEM cover and to the a-pillar. The designed sun visor does not fit in the current interior of the driver compartment but has been created as close as possible to fit the current space with only small adjustments to the interior. In addition, the components of the new sun visor needs to be redesigned, mainly the WEM cover, to allow the new sun visor to reach down to the lowest allowed point. The new concept has the potential to increase the visibility more efficient than the standard sun visor.
Solskyddets huvuduppgift är att förhindra att föraren och passagerarna blir bländade av solljus. Det är viktigt att solskyddet inte blockerar sikten samt att föraren har fri sikt så att kollisioner kan förebyggas. Dock är dagens lösning begränsad eftersom den endast täcker en viss del av det inkommande ljuset och dess funktion är beroende av huvudets position. Därför vill ÅF utveckla och förbättra dagens produkt till ett nytt koncept med hjälp av produktutvecklingsmetoder som förhindrar att föraren och passagerarna blir bländade. Produktutvecklingsprocessen omfattar olika faser. Genom att samla och identifiera kundernas behov och önskemål kunde en detaljerad kravspecifikation erhållas. Konkurrensanalys genomfördes för att skapa medvetenhet om vad som redan finns på marknaden idag. Nya koncept skapades genom brainstormning. Dessa nya koncept utvärderades genom konceptscreening och konceptscoring och ett slutgiltigt koncept valdes för vidareutveckling. Det slutgiltiga konceptet designades och utvecklades med alla ingående komponenter i CAD med hjälp av programvaran Catia V5. Ett materialval utfördes på de nya komponenterna med hjälp av CES Edupack och ett slutgiltigt materialvalsförslag för varje komponent presenterades. Det nya solskyddet består av en gardin som är kopplad till profiler i WEM covern och a-stolpen. En elektrisk motor i kombination med en fjäder kontrollerar solskyddets uppåtgående och nedåtgående rörelse till en exakt position. Föraren eller passageraren kan reglera höjden på solskyddet genom att trycka på en knapp. En fördel med det nya solskyddet är att läckage har eliminerats mellan solskyddet och WEM cover samt a-stolpen. Det nya solskyddet får dock inte plats i den nuvarande interiören men har designats så nära som möjligt för att passa i det aktuella utrymmet med endast små ändringar av interiören. Dessutom måste vissa komponenter designas om, huvudsakligen WEM covern, på grund av att gardinen inte går hela vägen ner till den lägsta tillåtna punkten. Det nya konceptet har dock potential att blockera det inkommande ljuset effektivare än det nuvarande solskyddet.

Abstract:
Bicycle helmets present complex geometries intended for protection and ventilation. Models often seem driven by esthetic considerations rather than by designs for optimal ventilation. To quantify the amount of flow entering a helmet, four bicycle helmets were investigated using flow visualization in a water tunnel, at representative riding speed for two helmet inclinations. Design features such as location of vents, visors and wall thickness of openings were examined as potential factors influencing ventilation efficiency. Cross-sections of streamtubes available for ventilation ahead of a helmet were evaluated. Results revealed that several helmet openings were seldom ventilated making them largely ineffective for forced convection under the given conditions. Velocities of the flow entering helmet vents were estimated to decrease by a factor &gt; 3 relative to the freestream and varied from one vent to another. The general trend observed for velocities was described by a simple analytical model based on channel flow.

Abstract:
The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports economic activity within park gateway communities. This report summarizes the annual economic contribution analysis that measures how NPS visitor spending cycles through local economies, generating business sales and supporting jobs and income. In 2020, the National Park System received over 237 million recreation visits (down 28% from 2019). Visitors to national parks spent an estimated $14.5 billion in local gateway regions (down 31% from 2019). The estimated contribution of this spending to the national economy was 234,000 jobs, $9.7 billion in labor income, $16.7 billion in value added, and $28.6 billion in economic output. The lodging sector saw the highest direct effects, with $5 billion in economic output directly contributed to this sector nationally. The restaurants sector saw the next greatest effects, with $3 billion in economic output directly contributed to this sector nationally. Results from the Visitor Spending Effects report series are available online via an interactive tool. Users can view year-by-year trend data and explore current year visitor spending, jobs, labor income, value added, and economic output effects by sector for national, state, and local economies. The interactive tool is available at https://www.nps.gov/subjects/socialscience/vse.htm.
