During the competition period highly skilled athletes who specialize in sailing experience fatigue, which manifests itself in the form of coordination disorders in maintaining balance. Therefore, it is important to determine the level and dynamics of the vestibular sense development, provide forecasts and perform the professional selection of athletes into the team. The research on the biomechanical process of maintaining the vertical posture by athletes in this kind of sport and the relevant psychological characteristics is reduced to establishing a qualitative and quantitative relationship between the coordinating properties of an athlete and their main psychological characteristics.

A general contractor’s ability to select proper subcontractors in foreign projects is a key competitive advantage. Toward this aim, a subcontractor selection model (CoSMo) was developed in this study. As a computational approach, the fuzzy sets method was employed because it can model human judgment by means of linguistic values, combining qualitative and quantitative decision criteria into an aggregate measure. Although the algorithm may be complex for easy acceptance by industrial practitioners, this disadvantage was minimized through a computer-supported system. In order to gain a better understanding of the current practice of CoSMo, a real world construction project was conducted. As a result, it was observed that CoSMo has high practical application and can be used as an advisory system by satisfying principal contractor’s requirements to reduce the risk involved in the selection of a subcontractor. Moreover, it gives an initial idea of how subcontractors perform on each decision criterion and allows the main contractor to understand the picture on the strong and weak points of each bidder and thereby to take conscious decisions.

In view of the dire state of literacy levels in South Africa and the fact that few literacy programmes provide research reports to evaluate best practices and effectivity, this article reports on the evaluation of a literacy project. The project, inspired by two children, is referred to as the Zoë-reading aloud project and targeted children in and around Upington in the Northern Cape, South Africa. The project was set up according to acknowledged reading promotion principles and it was structured to collect detailed data. Qualitative and quantitative data collection methods were used and a selection of methods provided reliability. The findings of the analysis of a collection of data for a period of 15 months revealed the best practices of the project. It highlights, for example, the need for financial assistance and challenges the concept of family literacy in low-literate and poor communities.

The guinea pig, as a livestock species, is still developing and growing throughout Peru and neighboring countries, as reflected by its increasing export since 2000. However, the selection of proven fertile males is tedious due to the absence of seminal parameter standards and the lack of safe semen collection techniques. Thus, pregnancy detection or live births are required for males’ selection. The purpose of this study was to describe the qualitative and quantitative semen parameters of fertile guinea pig males, to set reference values, and to validate a novel electroejaculation technique for the species. Semen was collected at weekly intervals from sixteen fertile males. Four transrectal electroejaculations were performed per male with 95% successful collections, yielding 39 viable semen samples. Seminal characteristics were as follows: pH 7.0 ± 0.13; ejaculate volume 0.67 ± 0.55 mL; sperm motility 90.81 ± 6.64%; sperm concentration 36.7 ± 28.41 × 106 sperm/mL; sperm count 20.09 ± 17.56 × 106 sperm/ejaculate; percentage of abnormal morphology 18.26 ± 8.52%; and percentage ubiquitinated spermatozoa 5.57 ± 6.28%. These values will serve as a reference to detect best breeding and infertile males rapidly. The described techniques are reproducible by commercial producers.

In the first and second generation of hybrids revealed different character of inheritance of basic qualitative and quantitative traits – dominance, heterosis, over-domination and intermediate inheritance, which allows to assume high efficiency of individual selections in the following generations, with the selection of transgressive forms. The actual ratio of distribution groups in F2 hybrids and the genetic control of these traits in parental forms by weight of 1000 seeds were determined. The source material and the perspective hybrid combinations in the breeding nursery were studied and the perspective numbers were distinguished according to the complex of features.

Study designs have numerous advantages and disadvantages that must be considered when addressing a research question, hypothesis, and objective. These include but are not limited to cost, feasibility, and ethical concerns. This review describes common study designs from the dysphagia literature with corresponding relevant examples for each design type. Further, discussion of the main differences between descriptive and analytical, qualitative and quantitative, observational and experimental, and retrospective and prospective study designs is provided. Specific aspects of various study designs, including matching, randomization, and blinding are also discussed. Finally, the importance of working closely with experts, such as epidemiologists and biostatisticians, in the early stages of research to assist with selection of the most appropriate study design and development of the research protocol is strongly recommended.

Adoption was a process of behavior change either in the form of knowledge, attitudes  and  skills  in  a  person  in  accepting  innovation  delivered  by  farming educator.The  research  objective  was  to  determine  the  level  of  Inpara  adoption   in swampyland with information output of Inpara adoption varieties in swampylands.The research  was  conducted  in  swampyland  on  Tapin  and  Hulu  Sungai  Utara  (HSU) district  during  February  to  May  2015.Total  sample  of  60  people  selected  randomly distributed in the six villages.  Data were analyzed descriptively both qualitative and quantitative  data  with  scoring  techniques.Results  showed  that  the  level  of  Inpara adoption  on  swampyland  remained  low,  i.e.  66.88%/year  on  HSU  district  and  (-74.56%/year) on Tapin district.The low level of adoption was due to the selection of varieties  that  had  been  developed  in  swampland,  namely  Ciherang,  Mekongga  and some  numbers  Inpari  adaptive  and  dissemination  of  varieties  Inpara  not  widely distributed to  swampyland  area.Despite the level of knowledge of  farmers on Inpara varieties was relatively high (68.3%) and attitudes of farmers toward Inpara varieties innovation  were  classified  agree  (72.9%),  not  yet  ensure  increased  adoption  of Inpara varieties in the two districts.

The inventory of the geological heritage of the state of São Paulo, Brazil, was carried out from 2012 to 2015 and resulted in the selection of 142 geosites in 11 geological frameworks representative of its geological history. Among the frameworks is the “Geomorphological units and landforms”, which includes fourteen geosites representative of the main geomorphological features in the area. Since these kinds of geosites are very suitable to interpretative and educational purposes, in this work we present both qualitative and quantitative assessments of the potential educational use of the geosites present in this geological framework. The assessment was carried out using the GEOSSIT platform, which was developed by the Geological Survey of Brazil (CPRM). The outcomes of the quantitative assessment made it possible to rank the geosites according to their importance. The geosites Jaraguá Peak and Itapeva Peak achieved the highest rankings, a result that reinforces their current use for tourist activities; on the other hand, the geosites Jureia Massif and Diabo Hill were the lowest ranked. The data obtained in this study suggest the need to establish educational measures that may increase activities of valorisation, dissemination and conservation of these geosites, and that take into account the geodiversity elements. In order to implement such measures, some support from public and private agencies is fundamental. In general, geosites present excellent conditions for the dissemination of geoscientific knowledge, making a key to the construction of a geoconservation conscience by the general public.
