Reconciling Organic-Medical and Psychological Paradigms in the Study of Counselors’ Cognitive Flexibility: a Critical Literature Review
Authors: Cahya Irani Luthfita , Hidayah Nur , Ramli M.
Published: March 2023

Cognitive flexibility of a counselor or therapist refers to their ability to adapt their cognitive approach to the unique needs and circumstances of their clients. This requires the ability to recognize and adapt to the unique cognitive processes and thought patterns of each individual. In the contextual development of cognitive flexibility in counselors, the organic-medical paradigm and the psychological paradigm have led to a revolution. The existence of these two paradigm perspectives necessitates a unique study that bridges the concept of understanding the two paradigms holistically in order to enhance the cognitive flexibility of the counselor. The purpose of this study is to investigate where the organic-medical paradigm and the psychological paradigm intersect when examining the cognitive flexibility of the counselor. The research design was quantitative and based on a critical literature review. The research focuses on three major components: (1) context issues regarding counselor cognitive flexibility from the perspective of the medical organic paradigm and psychological paradigm; (2) issues regarding the main implicit and boundary problems of counselor cognitive flexibility on professional work performance based on literature research data; and (3) the most promising questions for future research development. In this article, the research findings are discussed further.

Electrocoagulation process is widely used for the removal of pollutants from the industrial wastewater. In the present study, an attempt was made to investigate the performance of electrocoagulation process using alu-minum and iron electrodes to treat the metal ions present in the synthetic galvanic wastewater. The electrodes used are with and without perforations and it was observed that the efficiency of electrodes with perforation (80 %) was higher than without perforations (50 %). The removal efficiency of heavy metal ions increased with retention time and direct current. The optimized values of residence time, voltage, pH, current, electrode spacing were 160 min, 6 V, 5, 0.2 A, and 3 cm, respectively. The maximum removal percentage of nickel and copper ions using perforated iron electrodes was 90.7 % and 86.0 %, respectively, and for chromium using a combination of perforated iron and aluminum electrodes it was 93.1 %. The removal of metal ions followed pseudo second order kinetic model with current dependent parameters.

Produk pertanian baik buah buahan, sayuran dan bunga (hortikultura) maupun produk tanaman pangan terbatas dipasarkan secara lokal. Penyuluh lapangan dan para petani di lokasi itu sangat membutuhkan informasi pengetahuan pertanian maupun komunikasi untuk konsultasi permasalahan di lapang.  Tetapi, karena jarak yang cukup jauh dari ibukota (khususnya dari Universitas Lampung sebagai sumber pakar pertanian) diperlukan metode diseminasi hasil penelitian dari Universitas Lampung dan juga media komunikasi melalui aplikasi online. Sekelompok dosen Universitas Lampung telah mengembangkan suatu aplikasi yang diberi nama AGROPED. AGROPED merupakan sebuah aplikasi Pertanian Lampung berbasis mobile yang dibuat  sebagai alternatif bagi para petani untuk memasarkan hasil pertanian, mendapatkan konsultasi pertanian dan informasi terkait dengan pertanian. Petani akan dilatih bagaimana menjadi pelanggan AGROPED dan memanfaatkan fitur didalamnya termasuk fitur e-commerce dan konsultasi permasalahan. Kegiatan pengabdian ini bertujuan memperkenalkan, dan mempraktekkan aplikasi AGROPED kepada petani dan setidaknya petani penjual dan petani aktif menggunakan fitur konsultasi. Dalam pemasaran, 52% menjualnya kepada pengepul, dan 17.5 % menjualnya keberbagai kesempatan (pasar, pengepul, diambil langsung oleh pedagang). Berkaitan dengan aplikasi internet, 90.1 % petani yang di-survey memiliki HP Android, tetapi belum banyak digunakan untuk usaha tani mereka, 77.2% belum pernah menggunakan internet untuk mencari informasi harga, hanya 56.8% menggunakan internet untuk mencari info tentang pertanian.

Published: March 2023

Cassava peel is a waste from the cassava plant which has the potential to be used as ruminant animal feed. Processing of cassava skin with ammonia needs to be done to improve the quality of cassava skin. The research was conducted to determine the physical and chemical quality of cassava peels after amoniation. The study was analyzed using a completely randomized design (CRD) and the significant results were further tested using Duncan's multiple range test (DMRT). The treatment was T1 (cassava peels + 0kg urea); T2 (cassava peels + 0.02kg urea) ; T3 (Cassava peels + 0.04kg urea). Each treatment consisted of 5 repetitions. The organoleptic test was carried out with 30 test participants. The physical tests observed were color, texture and aroma. Chemical quality was determined through proximate analysis and Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX). Variables in the chemical quality test included dry matter, ash, crude protein, ether extract and crude fiber of cassava peels. The results showed that ammoniation of cassava peels affected the physical and chemical qualities of cassava peels (P<0.05). Ammoniation of cassava peel increases protein content up to 23.01% (T3) and reduces crude fiber up to 7.92% (T2). Increasing the level of urea can increase the process of degradation of starch structure in cassava peels.

The Quality-Adjusted Cyclical Price of Labor
Authors:   University of Rochester, Bils Mark ,   Federal Reserve Bank of Richmond,   NBER, Kudlyak Marianna ,   Federal Reserve Bank of San Francisco, Lins Paulo ,   University of Rochester
Published: March 2023

Typical measures of wages, such as average hourly earnings, fail to capture cyclicality in the effective cost of labor in the presence of (i) cyclical fluctuations in the quality of worker-firm matches, or (ii) wages being smoothed within employment matches. To address both concerns, we estimate cyclicality in labor’s user cost exploiting the longrun wage in a match to control for match quality. Using NLSY data for 1980 to 2019, we identify three channels by which hiring in a recession affects user cost: It lowers the new-hire wage; it lowers wages going forward in the match; but it also results in higher subsequent separations. All totaled, we find that labor’s user cost is highly procyclical, increasing by more than 4% for a 1 pp decline in the unemployment rate. For large recessions, like the Great Recession, that implies a decline in the price of labor of about 15%.

Published: March 2023

Los acontecimientos de los últimos meses en el Perú son consecuencia de la aguda crisis política que ha vivido el país en el último quinquenio, cuyos orígenes se remontan a 30 años atrás, con la imposición del modelo neoliberal. Los sectores enfrentados –la derecha que ha retomado el poder, tras la caída de Pedro Castillo, y un vasto movimiento popular, sin clara dirección política y que siente el poder usurpado por la primera– tienen agendas opuestas. Mientras que el sector conservador defiende el orden establecido, la sociedad movilizada quiere un cambio que se plasma en el reclamo de una asamblea constituyente. Evitar la proscripción es lo que permitiría una salida democrática.
The Meaning of the Social Purpose of School Education from Dewey's Perspective
Authors:   Korea Univ. Institute of Educational Research, Kim Dohyun , Kim Sanghyun
Published: March 2023

The purpose of this study is to find in the ‘social purpose of education’ that school education is still necessary in the future society despite various crisis factors inside and outside the school, and to clarify what the social purpose means, focusing on John Dewey’s view of education. To achieve this purpose of the study, Dewey’s books Democracy and Education, School and Society, My Educational Creed, and Experience and Education were analyzed. For Dewey, school education is a form of education as a social process rather than focusing on the individual, and it has characteristics as an open, purified, and simple environment. As a result, school education has no choice but to have a social purpose. The social purpose of education emerges in an era when education is biased towards natural purposes. It is also a purpose of a wider human dimension than a national purpose. It is not in conflict with personal goals and rather it is integrated. School education aims for social growth that goes beyond individual growth. And it is not a simple function, but a purpose concept with a clear intention and direction. The discussion raised according to this is the problem that the social purpose in the law and the purpose in dally life are so different that students learn a double mind.

Published: March 2023

Biogas plants are one of the most stable sources of renewable energy. Currently, there is a noticeable increase in the amount of post-production residues from agricultural production and agri-food processing (fruit and vegetable processing, fermentation, beet pulp, or lignocellulosic waste), which, can be used for biogas production after appropriate pretreatment. The aim of this study was to examine the possibility of using the biomass produced during the cultivation of grapes on a selected farm as a substrate for a biogas plant, taking into account the production process. The research was carried out in 2018–2020 in a vineyard located in the Sandomierz Upland in the south-eastern part of Poland. Own rooted vines were grown as a single continuous string with a trunk height of 40 cm and a length of one fixed arm approx. 0.9 m, on which six pivots were left every year after applying a short cut, from which 12–16 fruit shoots were derived, the so-called grapevines. Leaves were collected at random from three locations on the fruiting shoot, a total of 30 leaves in each replicate. Each sample consisted of 1/3 of the leaves collected at the bottom, 1/3 in the middle, and 1/3 at the top of the canopy. Leaf area was estimated with a model 3100 area meter on a sample of 30 leaves from each replicate. Both the quantity and quality of the obtained material as a substrate for methane fermentation were evaluated. Biogas yield tests in optimal conditions for mesophilic bacteria were conducted on three substrate samples referred to as ‘Regent’, ‘Seyval Blanc’, and ‘Solaris’. The yields of the tested material ranged from 51.0 to 59.0 Nm 3 biogas per Mg of biomass.
Regionalisation of watersheds with respect to low flow
Authors: Cupak Agnieszka , Michalec Bogusław
Published: March 2023

The aim of the study was to compare two grouping methods for regionalisation of watersheds, which are similar in respect of low flow and chosen catchments parameters (physiographic and meteorological). In the study, a residual pattern approach and cluster analysis, i.e. Ward’s method, were used. The analysis was conducted for specific low flow discharge q95 (dm3∙s–1∙km–2). In the analysis, 50 catchments, located in the area of the upper and central Vistula River basin, were taken. Daily flows used in the study were monitored from 1976 to 2016. Based on the residual pattern approach (RPA) method, the analysed catchments were classified into two groups, while using the cluster analysis method (Ward’s method) – into five. The predictive performance of the complete regional regression model checked by cross-validation R2cv was 47% and RMSEcv = 0.69 dm3∙s–1∙km–2. The cross validation procedure for the cluster analysis gives a predictive performance equal to 33% and RMSEcv = 0.81 dm3∙s–1∙km–2. Comparing both methods, based on the cross-validated coefficient of determination (R2cv), it was found that the residual pattern approach had a better fit between predicted and observed values. The analysis also showed, that in case of both methods, an overestimation of specific low flow discharge q95 was observed. For the cross-validation method and the RPA method, the PBIAS was –10%. A slightly higher value was obtained for the cross-validation method and models obtained using cluster analysis for which the PBIAS was –13.8%.

Published: March 2023

The content of structural carbohydrates and lignin are important assessment criteria of the feed value of meadow plants. It is affected by many independent factors, including among others its development stage during the harvest as well as climatic conditions, especially the amount of rainfall. During the years 2014–2016, plant samples were harvested at weekly intervals, respectively five times from late April to late May. The effect of harvest date on cellulose, hemicelluloses and lignin contents was evaluated. The chemical composition of plants was varied, depending not only on harvest date but also on the year of study. Regardless of the course of meteorological conditions in subsequent growing seasons, the increase of cellulose (from 236.5 to 297.9 g∙kg–1 DM), hemicelluloses (from 159.3 to 210.8 g∙kg–1 DM), and lignin (from 31.5 to 43.1 g∙kg–1 DM) in the following dates of harvest were observed. These parameters were also positively correlated with the total rainfall from the begging of vegetation season to the date of plants sampling (R2 = 0.65, 0.12 and 0.44 for cellulose, hemicelluloses and lignin, respectively), and with the average daily air temperature in the moment of harvest (R2 = 0.66, 0.32 and 0.52 for cellulose, hemicelluloses and lignin, respectively). The cellulose and lignin content, regardless of the harvest date, were significantly higher in the first year of the study (2014), when moisture conditions for plant development were optimal.

During evaluations of teat skin by the authors using National Mastitis Council procedures, teat open lesions (TOL) have been more commonly identified in dairies in the Northeast United States over the last 10 years. The TOL described here are found in all stages of lactation and in any age lactating cow, which is unique from TOL that present mainly in first lactation animals just after calving. Cows with these TOL exhibit more abnormal cow behaviors during the milking event. Based on the authors’ subjective field evaluations, dry teat skin condition appears to be a significant risk factor. Although there is a paucity of published literature, the other risk factors that the authors have observed are exposure to wind and significant temperature fluctuations, wet bedding, certain bedding additives, and occasionally mechanical, chemical, or thermal trauma. Teat open lesions have been observed in herds with all the common types of bedding. Treatment and preventative measures have focused on supporting skin conditions through higher emollients in the postmilking teat disinfection (PMTD) and controlling the environmental conditions to which the teat is exposed. This includes an evaluation of cow positioning in the stall as well as bedding levels, which influence bedding contamination. The accuracy of PMTD application can also have an influence. The objective of this narrative review was to search the current literature describing TOL, identify knowledge gaps, describe the authors’ field experience with TOL on dairy operations in the Northeast United States, and identify opportunities for future research.
Structural and pragmatic shifts in the development of newspaper headlines in the socialist and democratic period
Authors: Molnárová Patrícia
Published: March 2023

The newspaper headline is the first contact between the author and the recipient and in terms of stylistics, it is one of the compositional aspects of the text. In relation to the text itself, as well as to the communication partner, the headline fulfils an informative, engaging and especially in journalistic genres, persuasive function. Following the previous research focused on the 1960s, the aim of the study is to analyse and compare headlines in Slovak newspapers in the period of totalitarian and democratic establishment with a focus on the journalistic genre. The research sample, excerpted from the official discourse of the Communist Party of Czechoslovakia (1948 – 1956, 1961 – 1970) and the more recent Slovak mainstream e-discourse (2011 – 2021), contains almost 800 headlines to monitor the developmental tendencies of a given text component under the influence of changed extra lingual conditions. The aim of the research is to verify the expected linguistic and communicative modifications captured, for example, in a freer approach to the use of language. The given assumption expected at the structural-pragmatic level is conditioned by the dismantling of political-ideological control of the socialist period. At the stylistic-pragmatic level, we also assume a more direct and qualitatively more elaborate expressiveness in the language.
Language situation and position of Catalan in Northern Catalonia
Authors: Kadlec Jaromír
Published: March 2023

This paper focuses on Northern Catalonia, a territory ceded to France by Spain through the signing of the Treaty of Pyrenees in 1659. The focus is placed not only on the demography and the number of speakers using the Catalan language in Northern Catalonia but also on the linguistic politics and the use of the Catalan language in various areas of social life, especially in education. The school plays the most important role in the revitalization of the Catalan language, and without its active contribution, it is not possible to restore bilingualism in French Catalonia.
Contextual Sensitivity of the Lexemes Učiteľ [Teacher] and Učiteľka [Female Teacher]
Authors: Urbancová Lujza
Published: March 2023

The study deals with the lexical meaning of lexemes female teacher, teacher (male teacher and a generic meaning of the lexeme), which might be in Slovak influenced by context and discourse as well as by attitudes and gender stereotypes of interlocutors. In pragmatic research, the author focuses on semantic indeterminacy as an implicit component of lexical meaning determined by the socialization of interlocutors. Analysis of the lexemes female teacher, teacher and their collocations with the adjectives typical, crazy, burned out, in different contexts, has shown that the gender of the person referred to has an influence on the meaning. The implicit or socialized meaning of the lexemes of the feminine gender is frequently associated with those phenomena that are percieved negatively in society, while the names of the masculine gender do not contain this component.
Effects of Led Lighting Training on Response Time in Greco-Roman Wrestlers
Authors: Gierczuk Dariusz , Bujak Zbigniew , Cieśliński Igor
Published: March 2023

Introduction
Response time is one of the determinants of performance effectiveness in wrestling competitions. Its high levels help wrestlers fight more effectively when performing appropriate technical and tactical actions. Different factors such as a proper warm-up, unexpected situations, muscle fatigue, asthenic reactions, competition prestige and previous injuries may exert an influence on perceptual abilities (including RT and MT) and affect fighting effectiveness. Getting to know determinants of response time may provide a lot of valuable practical information that can be used in wrestling-related training. The study sought to determine changes in response time in Greco-Roman wrestlers produced by LLT.

Material and Methods
Twenty-four Greco-Roman wrestlers (age = 18.6 1.8, years of experience = 6.0 1.6) took part in the study. The wrestlers were divided according to two weight classes (lightweight and heavyweight). Within LLT programme, they performed special motor tasks using Batak Pro (15 minutes in total). Between the tasks, response time (reaction time and movement time) was measured. Reaction time test (RT, version S1) of the Vienna Test System was used in the study.

Results
Response time changed in a variety of ways (different directions and intensity of changes). The changes were noted both in RT and MT. Contrary to LLT, a standard warm-up did not contribute to an improvement in RT. The greatest changes were observed after ten minutes of exercising. Intragroup differences in response time grew smaller in the course of the task performance. No differences in response time were noted between wrestlers representing different weight classes.

Conclusions
Physical exertion within LLT affects response time in Greco-Roman wrestlers regardless of their weight classes. The most favourable changes occur after 10 minutes of exercising that requires high attentional focus (exercises performed after a standard warm-up). The type of warm-up and the exercises used may constitute a factor improving performance effectiveness. It is recommended that in a pre-competition warm-up, more time should be devoted to exercises requiring high attentional focus.

Published: March 2023

Introduction
The aim of the study was to assess the effect of caffeine and caffeine with guarana on the dehydration of young soccer players and the effect of dehydration on their reaction time.

Material and Methods
The study involved 57 players aged 16.8 ± 0.5 years, with an average body weight of 66.5 ± 9.3 kg, and height 178 ± 6.7 cm. An analysis of the body composition was performed. Thus, the results regarding body weight, adipose tissue, muscle tissue, BMI and body hydration were obtained. Next, the competitors performed successively a test for reaction time and speed over a distance of 5 and 15 meters with the use of photocells. After the tests, the players were randomized into 3 groups, where they received 200 mg caffeine, caffeine + guarana (200 mg + 40 mg), and placebo. Then, the players participated in a soccer training of medium intensity on the pitch, which lasted about 60 minutes. Immediately after completing the training, the procedure for testing reaction time and speed as well as body composition analysis were repeated.

Results
Water loss occurred in each of the study groups and was the highest in players consuming caffeine with guarana and caffeine, but these were not statistically significant differences compared to placebo. Lower BMI correlated with water loss; however, statistically significant differences were noticed only in the placebo group (p ---lt--- 0.001). Water loss also correlated with a smaller decrease in speed over a distance of the 5-meter sprint (p ---lt--- 0.039) and the 15-meter sprint (p ---lt--- 0.035), but only in the caffeine-guarana group.

Conclusions
Caffeine consumption in the amount of about 3 mg/kg of body weight and also caffeine with guarana did not result in significantly greater loss of water in young soccer players. The loss of water during training in players was almost 0.7 l and did not affect the reaction time. The obtained results are important in the context of consuming supplements based on caffeine and guarana for young footballers in order to improve parameters such as speed or reaction time. However, it is also worth conducting research on a group of adult players.

RELATION BETWEEN SELF-DECEPTION AND TAX EVASION IN BRAZIL
Authors: Pereira Ivone Vieira , De Ávila Lucimar Antônio Cabral
Published: March 2023

Objetivo: Identificar a relação entre autoengano e evasão fiscal no Brasil, tendo em vista que elas podem estar relacionadas, dada a diversidade comportamental dos contribuintes.
Referencial teórico: Conteúdos relacionados a autoengano e comportamento humano.
Método: A coleta de dados deu-se por aplicação de questionários da subescala Self-Deception Enhancement e a Impression Management no período de fevereiro e março de 2020. Utilizou-se da regressão logística sob a perspectiva univariada e multivariada para identificar a relação entre as variáveis.
Resultados e conclusão: Utilizando-se dos indicadores de cada constructo obtido na análise fatorial, verificou-se que o aumento na propensão ao autoengano diminui a chance de evadir fiscalmente. As motivações intrínsecas e extrínsecas dos contribuintes sugerem a necessidade de a gestão pública/privada estabelecer maior transparência tributária dos fatores socioeconômicos e fiscais para a redução e inibição de práticas de sonegação fiscal.
Implicações da pesquisa: Os achados são úteis para auxiliar a Administração Pública na implantação de estratégias eficazes na promoção da inibição de níveis e efeitos da evasão fiscal, considerando a diversidade de comportamento dos contribuintes, sem ignorar suas motivações intrínsecas, uma vez que estas são determinantes para compreender a atitude diante de práticas ilegais. Pelas consequências geradas à economia e à sociedade, a inibição à evasão fiscal se faz necessária para o seguimento do financiamento público e a garantia pelo respeito dos princípios constitucionais.
Originalidade/Relevância: O estudo aborda o tema por uma perspectiva que investiga o comportamento humano através de estratégias sociais que podem influenciar a prática de evasão fiscal e contribuir para a redução do gap tributário.
