Abstract This article discusses the construction of an intervention program on counting principles for first grade children, as well as the pilot study that put it into practice to evaluate its applicability (quality of proposals, duration and children engagement) and dynamics (contextualization, previous motivation, activity and systematization). Initial application was performed with ten children from a state school located in Porto Alegre (RS). A field diary was the instrument used for recording the sessions progress. The results showed a clear need for adjustments in the intervention (dynamics reorganization and selection of tasks), which were then made aimed at improving the program, enabling its future application in an experimental study.

The quality of multiple-choice questions (MCQs) can be determined by the discrimination index (DsI), difficulty index (DI), and distractor efficiency (DE) in post exam analysis. Selection of distractors is one of the most neglected aspects of MCQ preparation. The present study evaluated the effect on DsI by replacing nonfunctional distractor (NFD) with more plausible alternatives using a quasi-experimental study model. The DsI and NFD values were obtained from the MCQ examinations that were conducted during the year 2017 from 37 courses with each containing 50 MCQ’s in the College of Dentistry, Majmaah University. The post exam analysis results were informed to the course directors and the faculty were given orientation program about replacing the NFD’s with more plausible options. In the following year (2018), sixty percent of the previous year MCQ’s were used with modified NFD’s in those questions (1100 MCQ’s). The average DsI and NFD were significantly improved from the year 2017 to 2018 (P< 0.000) with significant negative correlation between them (P<0.000). This study shows that the psychometric properties of MCQs can be improved by creating better distractors. The researchers recommend providing faculty with more training on how to use distractors effectively in MCQ writing.

Purpose This paper aims to test the idea generation capabilities of online text-based focus groups as compared to the traditional in-person focus groups using sustainability in the hospitality industry as the idea generation topic. Idea generation quantity and quality are analyzed and the theoretical and practical implications for the hospitality industry are discussed. Design/methodology/approach An experimental study tested the quality of ideas generated by online versus in-person focus groups. Participants were purposively sampled from the hospitality program at a large southeastern United States university and randomly assigned into one of two treatment groups: online text-based or traditional in-person focus groups. During both treatment groups participants generated ideas focused on sustainability in the hospitality industry. Findings The online focus group generated a comparable quantity of ideas, in addition to a similar average quality of ideas and number of good ideas. Practical implications The generation of ideas and the selection of opportunities drive the innovation process through which firms can strengthen their competitive advantage and maintain and grow market share and profitability. The results of this study may assist hospitality firms in determining which form of qualitative research delivers the highest return on investment by generating the best ideas at the lowest cost. Originality/value This paper breaks new ground by assessing the effectiveness of idea generation in online versus traditional focus groups, comparing both the quantity and quality of ideas generated from an experimental study that uses random assignment.

Quality Of Health Services

Abstract. The quality of health services depends on the contribution of all the professionals involved in the system, including certain groups, usually forgotten and underrated, such as the health-transport technicians (HTT). With the aim of improving this group's performance, an intervention program, focusing on the development of the workers' technical and social skills, was designed in a collective of enterprises. Information about the first stage of this program, consisting of the assessment of these workers' social skills, is offered in this study. A specific questionnaire was developed: The Health-Transport Technicians Social Skills Questionnaire (HTT-SSQ), made up of three scales (assertive, passive, and aggressive behavior). It was administered to a large sample (N = 530) from the above-mentioned association. The psychometric properties of the questionnaire were analyzed, with quite satisfactory indexes of internal consistency and factor validity, and the group's deficiencies (excess or deficit) were evaluated.

The article discusses the reasonsfor an expert to participate in legal proceedings. The gnoseological reason for that consists of the bad quality of materials subject to examination that renders the examination either completely impossible or compromises objective, reasoned and reliable assessment of the findings. The procedural reason consists ofa proscription for an expert to collect evidence himself or herself. The author investigates into the ways of how an expert can participate in legal proceedings. If the defense invites an expert to participate in the proceedings, then it is recommended that his or her involvement should be in the presence of attesting witnesses and recorded in the protocol. In the course of the legal proceedings an expert has the following tasks: adding initial data, acquiring new initial data, understanding the situation of the incident, acquiring new objects to be studied, including samples for examination. An expert’s participation in legal proceedings differs from the participation of a specialist or an examination on the scene of the incident. The author describes the tasks that an expert solves in the course of legal proceedings, the peculiarities ofan investigation experiment practices, the selection of samples for an examination, inspection, interrogation.

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.

The construction and selection of a suitable bijective function, that is, substitution, is now becoming an important applied task, particularly for building block encryption systems. Many articles have suggested using different approaches to determining the quality of substitution, but most of them are highly computationally complex. The solution of this problem will significantly expand the range of methods for constructing and analyzing scheme in information protection systems. The purpose of research is to find easily measurable characteristics of substitutions, allowing to evaluate their quality, and also measures of the proximity of a particular substitutions to a random one, or its distance from it. For this purpose, several characteristics were proposed in this work: difference and polynomial, and their mathematical expectation was found, as well as variance for the difference characteristic. This allows us to make a conclusion about its quality by comparing the result of calculating the characteristic for a particular substitution with the calculated mathematical expectation. From a computational point of view, the thesises of the article are of exceptional interest due to the simplicity of the algorithm for quantifying the quality of bijective function substitutions. By its nature, the operation of calculating the difference characteristic carries out a simple summation of integer terms in a fixed and small range. Such an operation, both in the modern and in the prospective element base, is embedded in the logic of a wide range of functional elements, especially when implementing computational actions in the optical range, or on other carriers related to the field of nanotechnology.
