The main aim of this article is to describe central elements of, and the relationships among, three interrelated domains of inquiry. The first domain is Charles Peirce's semiotic theory which offers five concepts of special relevance to the other two domains: (a) primary components of the triadic sign, including the object, representamen, and interpretant; (b) the unceasing process of semiosis, or continuous growth of the developing sign; (c) the three forms of inference, of which Peirce's notion of abduction is of special interest; (d) the element of surprise in experience, and (e) the universal categories of Firstness, Secondness, and Thirdness that ground Peirce's overarching theory. The second domain incorporates the discipline of psychosemiotics, which is defined as the study of how we learn, understand, and use the signs of culture. The article outlines the nature and scope of psychosemiotics and emphasizes its grounding in Peircean semiotics, meaning‐making, and the five concepts listed above. The claim will be made that signs, semiosis, and meaning act through the seven signways outlined in the article and thereby bind the individual into the surrounding physical and cultural environments. The third domain is formal education, for which implications are presented as derived from Peircean theory and viewed through the psychosemiotic lens. In this perspective, all forms of education are semiotic processes grounded in signs and meaning‐making. Further, formal education consists of learning a wide variety of culturally‐valued signs by way of the seven signways and through processes that often differ from a technocratic, standards‐driven, accountability‐oriented approach to learning and instruction.

How We Speak When We Say Things about Ourselves in Social Media: A Semiotic Analysis of Content Curation

In this article I situate Peircean semiotics within Peirce’s larger phenomenological project. Because Peircean theory is directed at the analysis of specific instances of experience it provides a series of powerful conceptual tools for ethnomusicologists and scholars in other ethnographic disciplines. After revisiting the social potentials of Peirce’s primary sign types and their utility for ethnomusicological work, I explore the importance of Peirce’s three basic ontological categories-Firstness, Secondness, Thirdness-for understanding and analyzing musical experience. I suggest that these categories are useful for parsing out the whole range of musical states of mind-from trance and "deep listening" to the thoughtful planning of variations and contrasts during performance. Finally, I attempt to show the systematic nature of Peircean theory and why an understanding of different sign functions is necessary for comprehending the states of mind represented by the categories of Firstness, Secondness, and Thirdness. I use my own performance of string band music as a case study.

The problem of the Ukrainian semiotic metalanguage still remains a subject of controversy for those who are interested in the scholarly heritage of the greatest and an extraordinarily prolifi c American philosopher, logician (mathematical and general) and semiotician Charles Sanders Peirce (1839 – 1914). In the course of his polymathic researches he created numerous terminological neologisms. The latter are most commonly rendered into Ukrainian applying transliteration. Peirce was extremely fond of placing things into groups of three, of trichotomies, and of triadic relations. His theory of signs is also based on his ʻtriadism’. The article discusses the interpretation of the fundamental categories of Firstness, Secondness, and Thirdness as presented in Peirceʼs work “A Guess at the Riddle” and focuses on the challenges of rendering these and other important terminological units of Peircean semiotics into Ukrainian. The article contains excerpts from the above mentioned Peirce’s work translated into Ukrainian by the author of this paper and the issues of translating Peircean neologisms are approached with the aim of revealing logic in the management of semiotic realities and specifi cally the logic of constructing diff erent Ukrainian equivalents. The lack of the generally accepted tradition of translating semiotic terms brings to life many terminological variants used by diff erent Ukrainian scholars and translators. The present paper reviews some terminological variants used by Ukrainian semioticians and seeks to provide arguments to support the necessity of selecting Ukrainian equivalents using the native stock of morphemes instead of applying transliteration of the original English terms. Following this line of thought, the author suggests her options for rendering such key semiotic terms as Firstness, Secondness, Thirdness, representation and determination, representamen and interpretant and some others and claims that the suggested approach is justifi ed and can ensure the adequacy of the translation and the unifi cation of the Ukrainian terminology of semiotics. Key words: Charles S. Peirce, metalanguage of semiotics, terminological neologism, translation, native Ukrainian terminology.

The present study shows the results of six case studies referring to an intervention applied to mathematical learning difficulties. Participants were 8 to 12 years old. The intervention considered mathematics as a language and it is theoretically based on Bronfenbrenner's bioecological model, Vygotsky's sociocultural theory and Peircean semiotics. The objective was to work on the development of academic skills associating mathematics with interactional social skills. The analysis was based on qualitative data collected during the intervention process and quantitative data from scales and instruments with pre- and post-intervention measures. However, due to the COVID-19 pandemic context, some methodological issues were affected, mainly because the evaluations took place before and in the midst of the pandemic. Social impacts of the pandemic have unevenly affected participants, especially adolescents and children. The pandemic had a worse effect on adolescents than on children, especially regarding procedures that involve memory, and those with attentional problems also had worse results.

The verjuice sample (14.5 ± 0.2% total soluble solid [TSS] content) was concentrated (at 102 ± 2°C evaporation temperature) until reach 50% TSS content by applying ohmic heating at 13, 15, 17, and 19 V/cm voltage gradients. The total process times up to 50% TSS content were determined as 2,100, 1,500, 1,200, and 1,020 s for 13, 15, 17, and 19 V/cm, respectively. The electrical conductivity values increased until reach 32% TSS content and then showed a decrease until the final TSS content. The total energy consumption values increased as the voltage gradient decreased. The total power and specific water removal ratio (SWRR) values decreased as the voltage gradient decreased. The efficiency of ohmic heating assisted concentration process increased with the applied voltage gradient and it ranged from 71.27 to 75.22%. By evaluating the effects of ohmic heating conditions applied in the present study on total process time, total energy consumption, and process efficiency, 19 V/cm voltage gradients could be recommended to be optimum evaporation conditions of verjuice concentration in case of decreasing process time and higher energy efficiency.Practical applicationsFruit juices are generally concentrated to extend their shelf life. Therefore, for concentration purposes, various techniques, such as thermal evaporation, freezing methods, and membrane techniques, are applied in the fruit juice industry. This technique has some disadvantages, such as high energy requirements, the formation of undesirable compounds, high initial investment cost, and high failure rate to reach the desired total soluble solid content. The ohmic heating method, which is among the alternative heating methods, has advantages such as high energy efficiency, shorter processing time, higher product quality, and not causing wastewater. As a result of this study, it is thought that the verjuice samples were successfully concentrated up to 50% TSS content by using the ohmic heating method and this method can be used as an alternative method instead of the traditional method due to higher process efficiency and shorter process time.

Gasification-degradation reactions of polyethylene (PE) over NaX zeolite and silica-alumina (SA) catalysts were studied in a fixed bed flow reactor system at 452-526°C and under 19.7-37.5g-cat•min/g-PE. The initial values in terms of the extent of gasification (RgF) at 25.0g-cat•min/g-PE were 0.23 and 0.41 at 477°C over NaX and SA, respectively. These values of RgFwere significantly greater than 0.015 for thermal degradation. However, these catalysts were deactivated by coke deposition and the RgFafter 2.5 hours was 33-55% of the initial value of NaX or 65-69% of that of SA. Product distribution in terms of carbon number for SA was almost independent of process time and reaction temperature, but the ratio of olefin to paraffin for the C3 fraction and that for C4 fraction increased gradually with process time and reaction temperature. For NaX, the fractions in the C1-C3 range increased, but other fractions and ratios decreased with increasing process time, while the increase in the reaction temperature caused a complex change in product distribution. The isobutane produced was 1-5mol% or 10-14mol% of the total gaseous products formed over NaX and SA. The main products formed over both of these catalysts were C3 and C4 olefins. The apparent activation energy was 25.2kcal/mol for NaX and it was 14.7kcal/mol for SA. The activity of these catalysts was reduced by pyridine poisoning. Moreover the poisoning of SA catalyst with sodium ion caused sharp drops in the activity levels and brought about marked changes in product distribution. The product distribution obtained over a Na-poisoned SA was quite similar to that over NaX. From the results obtained in the present study, it was suggested that the gasification-degradation reaction of PE over SA proceeded through the carbonium ion mechanism, while the gasification-degradation reaction involved over NaX was complex, competitive reactions of both the radical and carbonium ion mechanisms.

Hitherto quantitative E.D. analysis has been carried out generally at pulse throughput rates up to about 5 kHz. Some commercially available E.D. systems are, however, now capable of rates exceeding 30 kHz. The present study is concerned with the feasibility of quantitative analysis at high count-rates, with the emphasis on applications to geological samples, especially silicates. Benefits of high count-rates include reduction in the time required per quantitative analysis. Also lower detection limits are obtainable with a constant time. Furthermore, flexibility with regard to count-rate is useful in combined E.D. and W.D. analysis.The Link Analytical XP2 pulse processor used in this study has a choice of 6 ‘process times’ (equivalent to the peaking time in a conventional amplifier). The throughput (or output) rate as a function of input count-rate for process times 1-4 is shown in Figure 1. The shortest (no. 1) gives a maximum throughput rate of 32 kHz, the dead time per pulse being 12 μS.

Facile synthesis of iron(II) doped carbonaceous aerogel as a three-dimensional cathode and its excellent performance in electro-Fenton degradation of ceftazidime from water solution

During speech pathology professional preparation there is a need for adequate student instruction with speech-restructuring treatments for adults. An important part of that clinical educational experience is to participate in a clinical setting that produces outcomes equivalent to those attained during clinical trials. A previous report showed that this is possible with a traditional, intensive speech-restructuring treatment. Considering the treatment process advantages and time efficiency of the Camperdown Program, it is arguably a compelling prospect for clinician education. Therefore, the present study is a Phase I trial of the treatment at a student university clinic, with a similar design to a previous report.

Considering the treatment process advantages and time efficiency of the Camperdown Program, it is arguably a compelling prospect for clinician education. The present study is a Phase I trial of the treatment at a student university clinic, with a similar design to a previous report. The design was a non-randomized Phase I clinical trial with 12 adult participants. Primary outcomes were per cent syllables stuttered (%SS) within and beyond the clinic, and speech naturalness scores from pre- and post-treatment stutter-free speech samples. Pooled %SS scores pre-treatment were 5.7, at immediate post-treatment were 1.0, and at 12 months post-treatment were 2.4. The group speech naturalness scores post-treatment did not increase to a clinically significant extent. Results essentially replicate the previous study by producing similar outcomes to those attained with clinical trials. The Camperdown Program is recommended as a clinical environment for speech-restructuring speech pathology student training.

For multivariable production process, knowing the first time of process really changes (change point) will help to accelerate the location of assignable causes and make measures for process adjustment. So effective estimating the change point is an important way to analyse the quality fluctuation of process. In the present study, an intelligent ensemble model for quality fluctuation analysis is proposed to estimate the variance change point in multivariable process. With the method, the process is decomposed based on moving window analysis, then different types of kernel functions are combined together to form the multi-kernel support vector machine model, which has combined the feature mapping capability of each basic kernel in the new feature space. The particle swarm optimisation is considered to search the optimised multi-kernel parameters. After that, each sub-characteristic is regarded as a pattern to be recognised to determine the change point by using the optimised intelligent ensemble model. Finally, a case study is conducted to evaluate the performance of proposed approach. It reveals that the method could estimate the time of variance change point in continuous production process accurately.

The present study was focussed on investigating the corrosion properties of plasma-oxidized and -nitrided CoCrMo alloys under different conditions. The structural properties of untreated and treated samples were examined by using scanning electron microscopy (SEM) and X-ray diffraction (XRD). Corrosion behavior of samples was mainly investigated by potentiodynamic polarization and electrochemical impedance spectroscopy in simulated body fluid solution. The results showed that corrosion resistance of the oxidized layers was better than that of the nitrided ones. The corrosion resistance of the alloys increased as the plasma oxidation process temperature and time increased. However, the corrosion resistance of the alloys reduced with increase in the process temperature and time after plasma nitriding process.

In automotive applications, friction stir spot welding (FSSW) has been practically used in the construction of aluminium car bodies. In this study, the weld strength and factors governing the weld strength in the friction stir spot welded aluminium alloy 6061-T6 were examined. The weld strength increased with the process time during FSSW up to 3 s, beyond which it decreased. The fracture path changed from the lapped interface into the shoulder edge as the process time increased, and the maximum strength was obtained at the process time when the transition of the fracture path occurred. The cross-sectional microstructure depended on the threads on the probe surface, i.e. the elliptical zone was formed in the stir zone by the threads, but an effect of the thread on the weld strength was hardly found. The present study suggests that the weld strength was strongly related to the size of the well-consolidated region, which was larger than the elliptical zone observed in the vicinity of the exit hole.
