Tourist Information

Travel Question and Answer (Q&A) platforms are widely used by travelers to exchange information online. This paper examined one such platform, Ctrip Q&A, to better understand the features of high-quality answers. The questions were first categorized into four types of information required by tourists (knowledge, efficiency, risk, and hedonic types) and then subdivided into more concrete elements, such as accommodation, food, and climate. The characteristics of high-quality answers on the platform were identified and a regression analysis was conducted to determine their importance. The study found that negative emotional expressions negatively impacted the quality of answers while the usefulness, richness, and amount of information had a positive effect. The usefulness of the answer content and quantity of information consistently predicted high-quality answers, whereas richness and conciseness were inconsistently related. Finally, the characteristics of high-quality answers to questions about different elements of tourism in the same category of tourist information varied significantly. This study may help travelers select and provide high-quality answers on tourism Q&A platforms. It may also assist platform operators in optimizing the features of their platforms, thereby improving user satisfaction and overall quality.

Filtration Device

The production technology of high-quality vodka used in Russia involves filtration through activated charcoal. To approach the quality of renowned Russian vodka, one prominent Czech spirit-producing company installed on its production premises a filtration device including a charcoal column, and launched test runs during which different filtration conditions were tested. Samples collected during the test runs were analysed by GC-FID and GC-MS with the aim to compare their composition; sensory analysis was an integral part of the evaluation. The results documented a positive effect of charcoal filtration on the quality of produced vodka, which was not reduced when higher flow rates were applied.

Abstract Context Previous studies have characterized code comments in various programming languages, showing how high quality of code comments is crucial to support program comprehension activities, and to improve the effectiveness of maintenance tasks. However, very few studies have focused on understanding developer practices to write comments. None of them has compared such developer practices to the standard comment guidelines to study the extent to which developers follow the guidelines. Objective Therefore, our goal is to investigate developer commenting practices and compare them to the comment guidelines. Method This paper reports the first empirical study investigating commenting practices in Pharo Smalltalk. First, we analyze class comment evolution over seven Pharo versions. Then, we quantitatively and qualitatively investigate the information types embedded in class comments. Finally, we study the adherence of developer commenting practices to the official class comment template over Pharo versions. Results Our results show that there is a rapid increase in class comments in the initial three Pharo versions, while in subsequent versions developers added comments to both new and old classes, thus maintaining a similar code to comment ratio. We furthermore found three times as many information types in class comments as those suggested by the template. However, the information types suggested by the template tend to be present more often than other types of information. Additionally, we find that a substantial proportion of comments follow the writing style of the template in writing these information types, but they are written and formatted in a non-uniform way. Conclusion The results suggest the need to standardize the commenting guidelines for formatting the text, and to provide headers for the different information types to ensure a consistent style and to identify the information easily. Given the importance of high-quality code comments, we draw numerous implications for developers and researchers to improve the support for comment quality assessment tools.

Abstract. The study concerned examination of 120 of young Pietrain and Duroc boars and hybrids descending from reciprocal crossing of those breeds. On 230th, 250th and 270th day of their lives, their sperm was given a detailed examination. It is assessed that Pietrain boars gave ejaculates of the lowest volume, lowest mobility, and the lowest total number of spermatozoa. Semen of boars of this group had also the highest percentage of spermatozoa with major and minor morphological changes, and defected acrosome. Along with the age of boars (from 230th to 270th day of life) there was a significant improvement of quality of semen of all of the groups except the semen of Pietrain boars. We detected the positive effect of crossing especially in hybrids boars descending from mating of Duroc fathers and Pietrain mothers. Even during the first evaluation, they gave the semen of the highest total number of normal sperms, with normal acrosome, and with the highest value of osmotic resistance test and the lowest activity of AspAT in semen plasma. That proves the high quality of ejaculates of those hybrids comparing to the ejaculates of the boars of other groups – purebreds as well as hybrids of the opposite combination, i.e. descending from crossing of Pietrain fathers and Duroc mothers. This conclusion suggests to use Duroc fathers and Pietrain mothers in production of hybrid boars.

The work is devoted to the search for answers to the question: “Are there any differences in the public procurement of customers who provide services of different quality?”. The article identifies the stages of the hospital procurement process in the contract system and highlights the main customer strategies used in the auction. The results of an independent quality assessment are examined and comparative hospital characteristics with low and high quality rating are conducted. The hospital needs according to the types of purchases and their annual volumes of contracts are analyzed. The advantages of competitive procedures are determined and the key factors affecting the level of competition with possible risks of unreliable execution of contracts are identified. The empirical study is based on the database which includes 5390 contracts of 2 hospitals in Moscow for years of 2011–2017. Using the methods of econometric analysis, in particular, the method of least squares and the difference in the average, the hypothesis is tested the high competition has a positive effect on the quality of medical services. The constructed regression models show that the customer providing high quality services has low competition and small rebates at the auction. At the same time there are more contract terms, delays in the supply of goods and services as compared with the customer providing low quality services. Thus it was found that the underestimation of competition at the auction indicates the desire of the hospital to guarantee a higher quality of medical services to patients while as aggressive bids of participants lead to the supply of poor purchases. The results of the study may be useful for the competent authorities in the development of legal acts for the participants of the contract system in the field of health procurement.

As part of a new harbor development, a new offshore breakwater will be constructed, for which the use of coastal protection plain precast concrete elements (AccropodesTM II) is required. The applicable exposure class is S1 (ACI 318). Over 4'000 elements have been produced. The owner required guarantees on the sulfate resistance of the elements before accepting them for usage in the project. For this, a revision of the documentation available was conducted, complemented by a thorough field investigation, measuring the coefficient of air-permeability kT (Swiss Standard SIA 262/1) of preselected elements (damaged during transportation) and elements representing the 28 weeks of production. The site NDTs confirmed a high quality of the majority of elements that were judged fit for the purpose. However, the NDTs confirmed the questionable quality of those cast during the initial period, requiring further evaluation before acceptance.The paper presents the results of: water aggressiveness, cement chemistry, strength quality control and air-permeability kT, and the criterion used to assess sulfate resistance of the elements.

Studies of online social influence have demonstrated that friends have important effects on many types of behavior in a wide variety of settings. However, we know much less about how influence works among relative strangers in digital public squares, despite important conversations happening in such spaces. We present the results of a study on large public Facebook pages where we randomly used two different methods—most recent and social feedback—to order comments on posts. We find that the social feedback condition results in higher quality viewed comments and response comments. After measuring the average quality of comments written by users before the study, we find that social feedback has a positive effect on response quality for both low and high quality commenters. We draw on a theoretical framework of social norms to explain this empirical result. In order to examine the influence mechanism further, we measure the similarity between comments viewed and written during the study, finding that similarity increases for the highest quality contributors under the social feedback condition. This suggests that, in addition to norms, some individuals may respond with increased relevance to high-quality comments.

The paper presents requirements to high-quality beef in terms of its general view, biochemical composition, taste and nutritional properties. The parameters which determine the taste, aroma, juiciness, tenderness of meat, as well as the strength and richness of the broth are given. Quality of beef obtained from animals of different beef breeds and their hybrids was assessed. Meat quality of the Hereford breed is higher than that of other most common breeds by the main parameters. The effect of the cow class on the meatproductivity of the young Hereford bulls was experimentally established. They were superior to animals of the control group in pre-slaughter weight by 25 kg (6.4%), slaughter weight - by 15.4 kg (7.5%), relative mass of flesh - by 7.8 kg, half-carcass weight - by 8.1 kg (7.6%). At the age of 20 months Hereford x Simmental steers of the 1st generation and heifers of the 3rd generation were characterized by high quality meat. Depending on housing conditions (with an area of 3.5 m 2 per head), the Kazakh-white-headed x Simmental steers of the 1st generation were in the lead in terms of meat quality. When fattened at the site, the Kazakh-white-headed x young Simmental bulls and heifers of the 1st generation were superior. The positive effect of semen production of Australian stud bulls on meat marbling of Siberian analogues (6 points) was experimentally proven. A new accelerated method of taking a sample of meat for research is described. In this method probes are taken from four easily accessible large muscles: m. supraspinatus, longissimus dorsi, m. iliopsoas (fillet), m. semimembranosus. Their biochemical composition is determined, after which the quality composition of carcass flesh is defined by a special formula with allowance for correction factors.
