A simple ultrasonic sensor coupled with a colour sensing system has been designed and built in the laboratory of the French National Institute of Applied Science at Rennes, and mounted on the laboratory's VESA mobile robot. It can distinguish simple configurations of obstacles and measure their distance from the robot, and within certain limits of illumination can classify obstacles to eight reference colours.

Identifying negative attitudes toward mental illness among students on nursing undergraduate degrees can help to design teaching strategies able to reduce the stigma attached to this condition. This study aims to assess attitudes toward mental health and intentions regarding future behavior in university nursing students initiating their training in the treatment of mental health problems (MHPs).

A descriptive, observational and cross-sectional study was designed. A sample of 162 nursing students completed scales to assess their attitudes toward mental health, stigma, predicted behavior and social desirability. Simple and a multiple linear regression was performed adjusted for the social desirability scale result.

Nursing students with previous experience of MHPs presented positive attitudes and behavioral intentions toward mental illness. Those who had no such experience before their training in mental health nursing presented certain stigmatizing attitudes. Attitudes toward MHPs may be affected by stigma and also by social desirability bias. The training in mental health care given to nursing students should aim to reduce its influence to help them carry out their future duties efficiently and compassionately.

This study demonstrates the relevance of university teaching plans, which should place special emphasis on promoting knowledge and developing skills and attitudes in nursing students undergoing training in mental health care to ensure optimal levels of performance in their future careers.

The evolution of Knowledge-Management (KM)-related literature has highlighted that Knowledge Management Systems (KMSs) have undergone massive changes in collaborative environments. Information-Systems-enabled KM seems to be the necessary response to the recent challenges posed by globalisation and technology dynamics to both large companies (LCs) and small and medium enterprises (SMEs).

This paper provides a systematic review about KMSs to offer an analytical overview of their role in supporting innovative forms of knowledge translation occurring in collaborative relationships. A sample of 129 papers was selected and analysed according to three perspectives: unit of analysis (LCs, SMEs), phases of the KM process (adoption, translation) and topic area (KM Practices, KM Tools, KMSs).

The findings highlight five literature gaps: (1) the role of KM practices supporting knowledge translation; (2) the impact of the alignment among KM practices, firm's complexity, dimension and culture on KM process; (3) the effect of KM tools on knowledge translation; (4) the variety of KMSs exploited in both LCs and SMEs; and (5) the alignment between organisational structure and information systems in KM context. Accordingly, 13 research questions were formulated.

The proposed research questions define a formal research agenda that could steer further research efforts about the KMS topic for improving the body of knowledge in the KM field. Scientific literature is currently lacking a contribution assessing the role of KMSs in supporting innovative forms of knowledge translation that occur in collaborative relationships.

The study investigates how cultural festival attendees’ familiarity and involvement may influence their overall satisfaction and future behavioral intentions towards the festival.

A path analysis is used to test the proposed model. The Sobel test is performed to determine the mediating role of attendee satisfaction on future behavioral intentions.

Attendee familiarity positively and directly impacts attendee involvement. Attendee satisfaction mediates the relationship between involvement and intention to return to the festival. The findings did not demonstrate a relationship between attendee involvement and intention to recommend the cultural festival. Attendees’ intention to return to the festival positively and directly impacts intention to recommend the festival.

For repeat cultural festival attendees, satisfaction is influenced by festival familiarity and involvement. As attendees become more satisfied with their festival involvement, their decision to return to the festival increases. The mediation effect of satisfaction indicates that this should be a priority, as it fully mediates the relationships. However, this is not the case as it relates to the intentions to recommend the festival.

The study contributes to literature on the impact of familiarity and involvement on repeat attendee satisfaction levels and how these relationships influence attendees’ decisions to return or recommend the festival. It is one of the first studies that investigates actual behavior of festival attendees, specifically in the context of an African-American cultural festival.

In his report for the year 1919, Dr. WILLIAM J. HOWARTH, C.B.E., Medical Officer of Health for the City of London, makes some very important observations in regard to the conveyance and handling of meat. He points out that a considerable responsibility rests upon the Sanitary Committee to ensure that the food passing through the City is of a satisfactory character, and the following matters are of interest. Meat is purchased at Smithfield by butchers from all parts of Greater London, and even from districts outside. It is removed from the market either in the purchaser's own carts, or in vans belonging to the numerous carriers who attend the market. From the stalls in the market it is carried to the waiting carts either by the purchasers or by market porters. The meat is either conveyed in trucks which are provided or on the backs and shoulders of these persons. The number of carts in waiting to receive meat is so considerable that during the busier hours they form practically a continuous barricade round the market. The rear parts of the carts are brought up to the edge of the causeway. These vans and carts carry a considerable amount of meat, in the form of quarters or cuts of larger or smaller size and offal. The division of the meat facilitates increased loading. It often happens that the supply arrives at the carts more quickly than it can be packed, and, as a consequence, it is allowed to stand about on the trucks for a longer time than is desirable. During this waiting period the meat is sometimes deposited on the footway. It should be noted that the sectioning of meat results in large areas of muscular tissues being exposed, and as the cut surface is moist, dust readily settles on it with the resulting disadvantages which are common to dust deposition; dust is excessive in dry weather as the streets in the loading‐up areas are fouled by the large number of horses which stand about. As regards the pavement, I need only mention that there is considerable fouling of the surface by blood and particles of fat, etc., which are trodden into a hard layer mixed with street refuse. The further risk of contamination by animals is obvious. Dr. HOWARTH further observes, I have had occasion officially to complain of one more than usually gross instance of piling meat on the ground. In this case the meat was separated from the wet ground by a layer of coarse sacking, the edge of the cover being also practically flush with the sides of the pile. The surroundings were foul. As regards the carts, the general practice is to cover the bottom of the cart with straw. In other cases a kind of sacking is used with or without an under layer of straw, and in exceptional cases white calico or some similar matter is used. Some of the carts do not come to the market in a thoroughly clean condition. They are certainly washed at times but not every day. The straw may be clean but it is not a suitable material on which to place the cut sections of meat. The cloths I have seen used day by day, being washed, in some cases, not oftener than once a week. Blood‐stained cloths should be washed before being used again. White cloths are more desirable, as staining and dirt readily show and this results in greater care being displayed. The procedure during packing is open to criticism. I have often seen, even on wet days, men, whose boots were soiled with road dirt, get into the cart to fill the front part. In doing so they soil the straw or cloth at the rear and on this soiled part meat is afterwards laid. If a white cover were used this would probably be rolled up at the back, whilst the front was being packed, and it would be straightened out as the packing progressed. I have seen a dog in a cart in which uncovered joints of meat were lying, and the dog would have been driven away in the cart if I had not objected. My protest in this and other cases was received badly. This is simply mentioned as an instance of disregard of an obvious precautionary essential. I have seen men stretching over uncovered meat to reach the front of the cart, and in exceptional cases have seen them with their feet on it. I have also noticed, at times, meat soiled with roadway dirt. As regards the transfer of meat from the stalls to the cart, I take exception to the infrequency of change of overalls by the porters, and to meat being carried on a man's head when he is wearing a cap which has done duty for weeks without being washed. Meat is not allowed to be placed on the floor of the stalls inside the market, and practically every trader has slightly raised wooden benches. There are no such facilities outside the market, nor are there any powers to require them to be provided. It seems strange that whilst in the slaughterhouses due regard must be paid to the observance of cleanliness, and in the markets the traders recognise the advantage of cleanliness and order, and further that butchers at their shops encourage brightness and cleanliness as is evidenced by good lighting, clean benches bright brass and steel fittings, and clean‐looking tiles to line the shop, so little regard should be paid to the elementary rules of cleanliness in the interval which elapses between purchase from the wholesale dealer and the reception of the meat at the shop.

We have observed in the reports of those engaged in the administration of the Acts several references to the practice of milking so that a portion of the milk is left in the udder of the cow, this portion being removed subsequently and not included in the milk sent out to customers. The inspector for the southern division of the county of Northampton reports that on a sample of milk being found deficient in fat to the extent of 17 per cent., a further sample was taken at the time of milking when a milkman was found to be not properly “stripping” the cows. He was warned. The analyst for the county of Notts writes: “The first strippings obtained before the milk glands have been normally excited by the milking are very low in fat yet are “genuine” milk in the sense that nothing has been added to or taken from it. It is nonsense to talk of genuine milk in the sense that everything that comes from the udder of the cow is to be taken as genuine milk fit for sale.” In a case tried before the Recorder of Middlesbrough, one witness said that among some farmers it was a common practice not to “strip” cows until after the milk was sent away.

The purpose of this paper is to develop a leakage model of metallic static seals, which can be used to accurately predict the leakage rate and study the corresponding seal characteristics. The metallic static seal is effectively applied to severe rugged environments where conventional seals cannot meet the needs. More research efforts for deepening the understanding of its seal characteristics are important for its effective and safe applications, of which the study about its leak is one key component.

In the microscopic observations of the turning surface that is general in the processing of flange surfaces, it is found that the spiral morphology is dominant, which had been also obtained by other researches. There are two potential leakage paths for the flange surface of spiral morphology, one is the radial direction perpendicular to the spiral ridges and the other is the circumferential direction along the spiral groove. Based on the microgeometry characteristics of spiral morphology, the micromorphology of turning flange surface is simplified for the calculation of leakage rate, and the simplified methods of the radial and circumferential leakage paths are presented separately. The topography of flange surface studied in this paper is actually measured, and the Abbott bearing surface curve is adopted to represent the micro-profiles parameters. The radial and circumferential leakage models are further developed based on the assumption of laminar flow of the viscous compressible gas.

The experiments used to verify the leakage models were carried out, and the experimental values are well agreed with the calculated values. As the contact pressure increases, the change rules of both radial and circumferential leakage rates are obtained and the obvious transition from radial leak to circumferential leak can be found. Using the proposed leakage models, the effects of the key micro-profiles parameters on the leakage rates are studied, and some specific conclusions are given simultaneously, which are favorable for the theoretical study and practical application of the metallic static seal.

By the interpretations of the micromorphology characteristics of turning flange surface, the leakage mechanism of the metallic static seal is further made clear. The proposed leakage model reveals the relationships between the key micro-profiles parameters and some sealing performances about the leakage and can predict the leakage rates of the metallic static seal used in various working conditions.

For the metallic static seal, the simplification of the radial leakage path and the radial leakage model are put forward for the first time, so the total leakage model can be systematically reported based on the micromorphology characteristics of turning flange surface. The effects of the key micro-profiles parameters on the seal behaviors including of the leak rate, critical contact pressure and transition from radial leak to circumferential leak etc are also clarified firstly.

This paper aims to examine the recent evolution of the regulation of statutory auditing since the passage of the Sarbanes-Oxley Act of 2002 in the USA by comparing the regulatory structures for auditing in the USA, France and Canada.

Using publicly available documents, the paper seeks to understand how the regulatory structures for statutory auditing have changed in the period since the passage of the Sarbanes-Oxley Act. The USA, France and Canada were chosen for analysis because prior to Sarbanes-Oxley the regulatory structures of these three countries were relatively distinct, whereas subsequent to the Act they appear to be becoming similar.

The authors interpret the increasing apparent similarity in the regulatory structures for statutory auditing in these three countries to be the result of external pressures from global capital markets for standardized regulatory practices. However, this apparent similarity may also be a form of “decoupling”, whereby actors in the institutional field of professional regulation, under pressures from powerful external forces, seek to enhance their legitimacy while maintaining internal flexibility and a certain capacity for resistance against external pressures in the institutional field.

The paper relies on a qualitative analysis of regulatory structures based on a review and analysis of publicly available documents and legislation. As such, it has limitations similar to other qualitative studies.

The regulation of statutory auditing is important to society both to assure the proper functioning of capital markets and to provide reliable information to the general public. Gaining a better understanding of the regulatory structures for statutory auditing advances the public interest.

There have been few prior research efforts that have examined the regulation of statutory auditing through the lens of new institutional theory.

This paper aims to investigate the effects of descent time spent with flaps extended on fuel burn (FB) and specific range for five different flight path angles (FPAs) ranging between 2.0° and 4.0° for a commercial aircraft.

A large data set of actual flight data (n = 475) of the same type of a frequently used commercial aircraft were investigated by using statistical methods.

The result of the comparison of the highest and the lowest FBs of flight profiles for each FPAs present that the fuel saving was achieved by keeping at as a high airspeed as possible and deploying flaps as late as possible, which is in line with the objective of delayed deceleration approaches. From analyzing the flight profiles, it was proven that delaying deceleration and also descending without flaps or with flap over a shorter time resulted in less FB of 101.1, 70.9 and 94.9 kg for FPA 2.5°, FPA 3.0° and FPA 3.5°, respectively.

This study differs from prior studies because it focused on the effects of the different vertical profiles on FB. Also, the use of real flight data recorder data in the analysis presents the originality of this study.

The purpose of this paper is to analyze the tourist landscape as represented in Turisme de Barcelona’s YouTube tourism promotional videos, looking at the landscape’s tangible locations, symbolic and tourist assets and the protagonists in an effort to interpret its storytelling in an overtourism context.

The mixed methodology is based on a visual content analysis of promotional videos posted on the official Barcelona tourism YouTube channel. Quantitative data analysis about the assets and their localization was completed with a qualitative assessment of the way these assets are displayed to unveil the narrative they convey.

The results highlight that Barcelona’s projected image is mainly based on tangible heritage (especially monuments), its recognizable cityscape and its eno-gastronomic assets. This rather conventional image is geographically concentrated on the neighborhoods perceived as tourist neighborhoods.

This analysis provides a critical reflection of the actual strategy of destination management organizations and the storytelling they transmit. The findings can help to orientate their future actions and provide a method of analysis that can be repeated for other destinations.

This paper sheds new light on the use of urban landscapes in nonstatic images both as a narrative subject and as a tangible tourist space in promotional discourse.
