Objective: to elaborate, validate and evaluate the reliability of the Safety Protocol for Pediatric Thirst Management in the immediate postoperative period. Method: methodological quantitative research, based on the assumptions on measurement instrument development. The protocol was elaborated after literature review, interview with specialists and observation of the child’s anesthetic recovery. The judges performed theoretical validation through apparent, semantic and content analysis. Content Validity Index was calculated for content validation, whose minimum established concordance was 0.80. Protocol’s reliability was evaluated in children between three and 12 years old in the Post Anesthesia Care Unit. Results: in its final version, the protocol consisted of five evaluation criteria: level of consciousness, movement, airway protection, breathing pattern and nausea and vomiting. It presented easy comprehension and relevant content, and all indexes exceeded the minimum agreement of 0.80. Pairs of nurses applied the protocol 116 times to 58 children, resulting in a high reliability index (kappa general = 0.98) Conclusion: the unprecedented protocol developed is valid and is a useful tool for use in anesthetic recovery, aiming to assess safety for reducing the thirst of infant patients.

Objective: to verify the association between the health-related quality of life of chronic renal patients on hemodialysis with sociodemographic, clinical, depression and medication adherence characteristics. Method: a cross-sectional study with 183 chronic renal patients undergoing hemodialysis in the state of Rio Grande do Sul, Brazil. A sociodemographic and clinical questionnaire, Kidney Disease and Quality of Life Short-Form, Beck Depression Inventory and Morisky Medication Adherence Scale - eight items were used. Among the variables, comorbidities, complications of kidney disease and intercurrences during and after hemodialysis were evaluated. The analysis was performed with descriptive and analytical statistics. Results: 55.2% of the patients were 60 years old or older, 35.0% were hypertensive, with regular quality of life, average of 62.61. Scores below average in the dimensions of quality of life were mainly associated with repetitive infections and edema as complications of the disease, pain during hemodialysis and weakness afterwards. Low drug adherence resulted in a worse quality of life, impacting ten of the 20 dimensions evaluated and depression in all, except for patient satisfaction. Conclusion: reduced quality of life in this population is associated with depressive symptoms, complications such as repetitive infections, pain and anemia, weakness after the dialysis session and low medication adherence. Actions aimed at changing these factors can promote well-being.

Published: July 2020

ABSTRACT Hydrogel hydration capacity in solution was evaluated at different levels of electrical conductivity (EC) using nitrate, phosphates, sulfates, and salts of calcium, potassium and magnesium. Four sequential experiments were performed using potassium polyacrylate copolymer. The first experiment aimed to determine the lowest hydrogel dose, at which occur maximum deionized water absorption. The test was assembled in a completely randomized design with six hydrogel doses (1, 2, 4, 6, 8 and 10 g L-1) and four replicates. The second experiment consisted of testing the sucrose P.A. doses (0, 1, 2, 4 and 6 %) in order to evaluate the change in osmotic potential of the solution on hydrogel hydration. The third and fourth studies were carried out in a complete randomized design, using a 6 x 3 x 2 factorial scheme with four replicates. For the third experiment, the factors were six levels of EC (0; 0.25; 0.50; 1.00; 1.50 and 2.00 mS cm1) increased by the addition of three anions (NO3-; PO43- and SO42-) along with counter-ions Ca++ and K+. For the fourth experiment, the same six levels of EC were achieved by adding the three cations (Ca++, Mg++ and K+), along with the counter-ions Cl- and SO42-. Hydration capacity of the hydrogel decreases when the ionic concentration of the solution increases and the reduction of the osmotic potential through the addition of sucrose does not interfere in its swelling capability. Anions and cations in the solution negatively influence the process of the hydrogel hydration. The most pronounced effect is for those with higher valence.

Published: July 2020

Abstract Capitulum wilting and neck bending are the two important complications that impair the post-harvest quality and vase life of the gerbera cut flowers. The present study investigates the effects of pre- and post-harvest treatments of spermine (SPER), γ-aminobutyric acid (GABA) and β-aminobutyric acid (BABA) on the vase life, qualitative features and enzyme activity of gerbera cut flowers ‘Stanza’. The pre-harvest treatments (1 mM doses) were applied by foliar spraying, and the post-harvest were by pulse treatment (5 mM doses). The flowers kept their quality longer in pre and post SPER and GABA treatments. The longest vase life was recorded in pre-SPER (14 days) and pre-GABA (13 days) compared to BABA treatments and controls (9 days). Neck bending was observed more frequently in controls whereas SPER and GABA showed a lower neck bending rate at 9 days after harvest. The highest vase solution uptake, total soluble solids, total flavonoid, total protein, the activities of catalase, peroxidase, superoxide dismutase, phenylalanine ammonia-lyase, and ascorbate peroxidase, besides the lowest neck bending, electrolyte leakage, malondialdehyde, H2O2 and polyphenol oxidase activity were observed in pre-SPER treatment and subsequently in pre-GABA. Pre- and post-harvest treatments with β-Aminobutyric acid (BABA) had no significant effects on cut flowers compared to SPER and GABA, although showed slightly better effects than water control. It is therefore suggested that pre-harvest treatment using SPER and GABA can improve the vase life and quality of gerbera cut flowers.

Published: July 2020

Abstract During in vitro propagation, cytokinins (CKs) and auxins (AUXs), such as 6-benzylaminopurine (BAP) and 1-naphthaleneacetic acid (NAA), are often used to induce adventitious shoots and roots, respectively. However, it is not clear how CKs affect plants over a long period of in vitro propagation as well as the synergy of direct exposure to AUX with previous CK treatments. The aim was to assess the physiological and anatomical responses of Alcantarea imperialis in function of the interaction of both previous BAP treatments and direct NAA exposure during in vitro propagation. Plants previously grown in vitro were transferred to media containing 0, 5, 10 or 15 μM BAP. After 60 days, the adventitious shoots from each previous BAP treatment were subcultured in media with 0, 2 or 4 μM NAA. Pigment content, anatomical and growth traits were assessed in the plants from each treatment. Both previous BAP treatments and direct NAA exposure altered the anatomy and pigment contents of plants as well as their growth traits. BAP induced negative effects over the long term on physiological status as well as changed the plants’ anatomy. NAA supplementation in the medium can partially reverse the negative effects induced by BAP. The application of 2 μM NAA during in vitro rooting improved the plants’ quality.

Published: July 2020

Abstract The flowers retail trade has shown good potential for development in agribusiness, despite the growth. Thus, in order to support a better understanding of the current scenario, it is presented the result of a research that sought to promote a classification by Porter’s Strategic Taxonomy, revealing what were the main lasting competitive advantages in the segment. In this context, a descriptive exploratory research was carried out between July and October 2019, where 23 flowers retailers in Paraná Coast, South of Brazil agreed to participate in the survey. The result of the classification of Porter’s taxonomy revealed that most retailers use the differentiation strategy (n = 52%), followed by the focus strategy (n = 48%), with no retailers that adopt the strategy of leadership in cost. The main threats from competitive forces were the bargaining power of the suppliers and the threat of substitute products. The main commercial tactics, which in the interviewees’ perception resulted in lasting competitive advantage, were the quality of the flowers sold, the experience in the flower segment that generated differentiated service, the offer of products different from the traditional ones and lower prices. The strategic typologies of Porter’s taxonomy adopted by retailers in Paraná Coast, in the current scenario, seem to be able to minimize the effects of competitive forces and they are able of generating sustainable competitive advantages.

Published: July 2020

Abstract This research was carried out to evaluate the effects of copper nanoparticles (CuNPs) on the postharvest physiology of carnation and chrysanthemum cut flowers. Synthesized CuNPs were applied at 10 and 20 mg L-1 to both cut flowers by the pulsing method. The physicochemical characteristics and the activity of antioxidant enzymes were measured on 0, 3, 6 and 9 days along the vase life. According to heat map analysis, changes in measured parameters were affected by flower type > vase period > CuNPs concentration. Results also showed that treating the two species of cut flower with CuNPS by the pulse treatment improved the relative fresh weight (RFW), vase solution uptake (VSU), membrane stability index (MSI), flower diameter and total soluble carbohydrate (TSC). Meanwhile, a decrease in both bacterial population of the stem end and the hydrogen peroxide (H2O2) was observed. In comparison with the control, CuNPs at 20 mg L-1 by pulse treatment almost increased the vase life in both cut flowers by 30%.
LA ADMINISTRACIÓN CIENTÍFICA DE LA EDUCACIÓN Y LA CONDICION CONTINGENTE DEL SER HUMANO
Authors: Losada-Sierra Manuel
Published: July 2020

RESUMEN La administración científica de la educación ha llevado a que las instituciones educativas muestren en los últimos años un marcado interés por los rankings, la rendición de cuentas y por una educación de calidad basada en la excelencia individual. Frente a esta dinámica, el presente trabajo muestra que las exigencias de una sociedad que ha venido de experiencias conflictivas o que quiere formar ciudadanos solidarios, requieren un cambio de perspectiva desde la autonomía individual hacia la construcción de escenarios de cooperación y respeto por el otro. Mediante un análisis teórico, este artículo muestra la insuficiencia del modelo taylorista de educación y propone una educación para la incertidumbre como apertura hacia la cooperación y la solidaridad.

Published: July 2020

Abstract This theoretical and reflective study aimed to assess the contribution of the ISO/TR 12300:2016 document for the mapping of nursing terminology. The referred document and related articles were used as an empirical framework. The study analyzed the content of the document, highlighting cardinality and equivalence principles. The standard presents conceptual and operational basis for mapping, with cardinality and equivalence as the support for the categorization of cross-terminology mapping in the area of nursing. Cardinality verifies candidate target terms to represent the source term, while the equivalence degree scale checks semantic correspondence. Among the principles included in the ISO/TR 12300:2016, cardinality and equivalence contribute to the accurate representation of the results of the cross-terminology mapping process and its use should decrease inconsistencies.

Published: July 2020

Um novo vírus denominado Sars-CoV-2, ou COVID-19, surgiu no final do ano de 2019 e causou diversas modificações em todo o mundo. Diante disso, os países estabeleceram medidas preventivas contra essa pandemia, tais quais o isolamento social, uso de equipamentos de proteção individual (EPI’s) e cuidado com indivíduos enquadrados nos chamados grupos de risco, como idosos, hipertensos, doentes crônicos e recentemente, as gestantes e puérperas foram inclusas. Para as puérperas, a amamentação é um momento primordial, que, além de um momento de alimentação natural, é uma oportunidade de fortalecer o vínculo mãe-bebê. Visando uma atenção mais cautelosa para uma possível transmissão de COVID-19 durante a amamentação, as medidas preventivas para esse ato podem dificultar esse binômio e trazer prejuízos para ambos.

Correlation of mescaline concentrations in Lophophora williamsii (Cactaceae) with rib numbers and diameter of crown (U.S.A.)
Authors: Newbold Richard , De Silva Sohan , Terry Martin
Published: July 2020

Lophophora williamsii, peyote, is a small cactus growing to approximately 10 cm in diameter with a flat to dome-shaped spineless crown with fissures or ribs that develop following the Fibonacci series and whose numbers indicate relative degree of maturing. In this study crown tissue of 30 wild-collected specimens was analyzed to determine whether there was a correlation between the concentration of the primary alkaloid mescaline in crown tissue with the average diameter of the crown. We also compared mescaline concentration in three groups of ten individuals: 5 ribs (juvenile stage), 8 ribs (intermediate), and 13 ribs (elder/mature stage), since these Fibonacci numbers are the most stable and long-lasting on L. williamsii. This was designed to test the hypothesis that there is a positive correlation between mescaline concentration and both diameter and rib number. Nine greenhouse-grown specimens were likewise analyzed to serve as a control group for the study. All 39 tissue samples were subjected to an alkaloid extraction procedure followed by an acid-base washing procedure. Mescaline was identified using liquid-chromatography and mass spectroscopy and then quantified using reverse-phase high-pressure liquid chromatography. The Pearson’s Chi-squared test showed no statistical correlation between increasing mescaline concentration and increasing rib numbers for field-collected samples and greenhouse?raised control samples. Field-collected samples: P-value of 0.392; greenhouse control samples: P-value of 0.313. Similarly, field and greenhouse samples showed no statistical correlation between mescaline concentration and average diameter of the crown. Field-collected samples: P-value of 0.251; greenhouse control samples: P-value of 0.229. This study contributes to the understanding of this vulnerable species and to approaches to its overall conservation and the preservation of Native American culture.

Published: July 2020

Abarema glaucum is a tree species native to Cuba, Hispaniola and Bahamas. It is considered Vulnerable to extinction in Cuba. The evaluation in Cuba also warns of the need to carry out population studies of the species. This work made the assessment of the status of Abarema glaucum in Artemisa, where the species had been reported before the half of 20th century. For this, the population structure was characterized; amount of accumulated aerial biomass in the region was estimated; and the threats to its conservation in the region were identified. Abarema glaucum has less than 250 individuals, with less than 50 mature individuals, dispersed between three sites in Güira de Melena y Alquízar. The diameter and height vary between 0.03 and 36.31 cm, and 0.05 and 15 m, respectively. The accumulated aerial biomass is estimated between 3 and 4 metric tons among 33 adults. The individuals are aggregated with good natural regeneration, but low recruitment towards older age phases. It is a species dispersed in patches of remaining forest in the region, where the risk of fire, logging, trampling, as well as the degradation of its habitat, constitute threats to its conservation. Logging could delay and even prevent flowering in the adults. The logging and the continuous decline of the quality of the habitat are putting the sustainability of the species in the area in danger.
Finding of the Thermophilic Harpacticoid Species Elaphoidella bidens (Schmeil 1893) in the Vychegda River (Northern Dvina, White Sea Basin)
Authors: Fefilova Elena B.
Published: July 2020

A harpacticoid copepod (Copepoda: Harpacticoida) species, Elaphoidella bidens, which was new for the North-East of European Russia, was found in the Vychegda River in July 2018. The species was identified in the area where heated wastewater is discharged from the wood-processing plant. The species was found in the extreme north of its range (61°48′ N). The present study compares the morphological, biological and ecological properties of this species with those of another native representative of the genus – E. gracilis. Comparison of morphology of the Vychegda E. bidens and individuals from tropical populations (New Zealand, Borneo, Vietnam) and populations of the temperate zone (Romania, Lake Glubokoe in Moscow region) showed that the structures of their antennae, body somites, swimming and rudimentary legs, and the caudal rami were similar in representatives of all populations. The fact that a thermophilic species was found for the first time in the northern region is indicative of potential changes in fauna diversity caused by thermal pollution or warming

Published: July 2020

Polyhydroxyalkanoates have attracted much attention as biodegradable alternative to petroleum-based synthetic plastics. Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] copolymer is one of the best characterized PHA copolymers because of its high commercial potential. However, commercial use of PHAs has been limited by their high price. One approach to reducing the cost of PHA production is to use inexpensive carbon sources (fatty acids, plant oils, etc.). The aim of this work was to study synthesis of P(3HB-co-3HV) by the Cupriavidus necator B-10646 bacterium grown on oleic acid and different biochemical precursors of 3HV. Bacterial cells were grown for 72 h at 30°C and 200 rpm on an incubator shaker. Salts of propionic or valeric acids were used as precursors of 3HV. The content and the composition of the polymer were determined by gas chromatography of fatty acid methyl esters. Lipids and polymer were extracted from biomass using the method of Folch. The addition of potassium propionate and valerate did not inhibit bacterial growth and polymer synthesis, the cell concentration and polymer content reaching 9.3-9.5 g/L and 80-83%, respectively. The addition of potassium valerate or propionate led to the synthesis of (P(3HB-co-3HV)) copolymer containing 21.2 and 14.3 mol% of 3HV, respectively. The number average molecular weight (Mn) of the polymer synthesized by the bacterium on oleic acid alone was 220 kDa; the polydispersity of the polymer was 3.5. The polymer synthesized in the presence of potassium valerate and propionate was characterized by a lower Mn (156-178 kDa) and a higher polydispersity of the polymer (4.4-4.9). The main fatty acids (FA) of intracellular lipids were oleic (33.26% of the total FA) and palmitic acid (27.48% of the total FA). The addition of potassium propionate or valerate did not cause any significant changes in the composition of the FA of intracellular lipids of the strain studied. This study demonstrates the ability of C. necator B-10646 to synthesize P(3HB-co-3HV) from mixtures of oleic acid and 3HV precursors. The data obtained can be used to develop and implement an economically feasible process of the P(3HB-co-3HV) production

Published: July 2020

The effect of oxidizing agents on the stability of bis (2,4,4-trimethylpentyl) dithiophosphinic acid (НR, Cyanex 301) and its extracts with Cu, Ni, Co, and Zn in decane and toluene was studied. It was shown that the stability of НR and extracts varies in the following series of oxidizing agents: HNO3> H2O2> J2. In a mixture of Cyanex 301 with trioctylamine, the oxidation of the extractant is much more effective than with Cyanex 301 alone. The degree of degradation of Cyanex 301 is higher than that of extracts, which indicates a higher stability of НR salts in comparison with the acid itself. The main oxidation products of Cyanex 301 and its extracts (NiR2 and ZnR2) with HNO3, H2O2 and J2 were determined

Scientific and Theoretical Modernization of the Concept of Syntax of the Ukrainian Language in Higher Education Textbooks
Authors: Mamalyha Anastasiya , Bykova Olga
Published: July 2020

The article deals with long overdue, topical issues of modern scientific and theoretical coverage of syntax of the Ukrainian language in higher education textbooks, in connection with signifi-cant new processes of scientific understanding of the system-structural organization of lan-guage, in particular its syntax, its hierarchically interconnected links. The objective of the article is to identify the real state and direction of the scientific and theoretical modernization of the concept, and, accordingly, the syntax course of the Ukrainian language in higher education textbooks in relation to the current development of science in the field of syntax. In the last decade of the twentieth century the textbooks related to syntax of the Ukrainian language with certain innovative content began to appear. In order to investigate their peculiarities, the direc-tion of updating was applied, first of all, by the following methods: analysis, synthesis, descrip-tive method – for separation, comparison, generalization of new syntactic aspects, units, terms revealed.

The methods of system analysis, induction, deduction have been used to find out the conformity of transformations to the principles of systematicity as a basic feature of the structure of a syn-tactic system. Supporting innovative processes of updating the editions related to syntax of the Ukrainian language, the authors considered it necessary to use the system-structural and communication-functional approaches to the study of text, its units, patterns of text-making, and also from these positions to provide an assessment of achievements, and in some cases disadvantages
of the updated educational literature. The result of the first frontal analysis of textbooks related to syntax of the Ukrainian language, which replaced the traditional ones, was first of all the conclusion that the performed research showed departure from the so-called «pretextual grammar» in them and going beyond the sentence to find out the essence of syntactic categories, structure of units and, finally, the whole structure of syntactic system in a multifaceted array of text-making as the final one for communication purposes, but unconventionally – at the sentence level, and at the text level – respectively with the modern scientific perspectives.

Effective currency risk management using various derivatives is particularly important under increased market volatility. The risk is relatively higher for longer than shorter time frames. This study highlights the implementation of selected instruments for long-term hedging. It presents the application of cross-currency interest rate swap as a currency risk hedging tool used by Polish exporters, mainly manufacturers generating their revenues mostly abroad (in euro area), exposed to negative exchange rate fluctuations. The paper covers issues related to the pricing, market risk estimation and collateral required in the OTC market, as well as undertakes a sensitivity analysis in search for exchange rates at which margin call occurs. There is a comparative analysis and back test simulation conducted using market data from exchange and money markets. The study emphasized that the analyzed instrument meets the expectations in terms of hedging the company cash flows, as well as may generate additional benefits due to the still existing interest rate differential.
China’s Foreign Investment Encouraged Catalogue and Negative Lists as a Tool of Foreign Direct Investment Attraction
Authors: Jakubczak Jacek
Published: July 2020

Theoretical background: Due to the growing maturity of Chinese market the country needs to adjust its policy regarding foreign direct investment (FDI), i.e. to increase openness for FDI, to keep control over them in key industries and to influence their inflow in desired industries and regions. Adopting the negative-list approach and changes in both the negative list and encouraged industry catalogue provides tools for this challenge.

Purpose of the article: The purpose of this article is to present how changes in China’s Foreign Investment Encouraged Catalogue and Negative Lists both in free-trade zones (FTZs) and at the national level are used as a tool for managing country’s FDI inflow.

Research methods: Analysis of legal documents and reports as well as literature review.

Main findings: Starting from the adoption of negative-list approach in FTZs in 2013, the negative lists had been drastically reduced both in reference to FTZs and national level. Those reductions lead to a decrease in China FDI restrictiveness index. FTZs were used as a testing area for both the negative list composition and negative-list approach itself. Negative lists allowed the state to keep control over FDI in key industries allowing, at the same time, greater freedom for foreign investors. Encouraged catalogue is used not only as a tool for attracting FDI from desired industries but also for addressing regional inequalities.
Audiodeskrypcja w percepcji sztuki przez osoby z niepełnosprawnością wzroku
Authors: Palak Zofia , Tukiendorf Karolina
Published: July 2020

Audiodeskrypcja, czyli słowny opis obrazów i treści wizualnych, umożliwia osobom z niepełnosprawnością wzroku pełniejszą i bardziej adekwatną percepcję sztuki filmowej, teatralnej, plastycznej. Audiodeskrypcja poprzez krótkie, precyzyjne i obiektywne opisy scen umożliwia widzom z niepełnosprawnością wzroku samodzielną interpretację treści wizualnych, pozwala podążać za rozwijającym się wątkiem historii oraz usłyszeć i zrozumieć, co dzieje się na ekranie. W filmie, audycjach telewizyjnych audiodeskrypcja przybiera postać dodatkowej ścieżki dźwiękowej umieszczanej między dialogami. Jest to technika wspomagająca. Nie zastępuje ona umiejętności obserwacji osób niewidomych i słabowidzących. Pomaga rozwijać wyobraźnię osób niewidomych, ułatwia rozumienie przekazu sztuki, pozwala na udział w życiu kulturalnym i społecznym. Tworzenie dobrej audiodeskrypcji jest niezmiernie trudnym, czasochłonnym i kosztownym przedsięwzięciem. Mimo dużej różnorodności potrzeb, oczekiwań oraz posiadanych doświadczeń życiowych odbiorców audiodeskrypcji konieczne jest wyznaczenie obowiązujących uniwersalnych standardów i zasad tworzenia opisu, aby optymalizować percepcję sztuki mimo utrudnień sensorycznych. Audiodeskrypcja jest dużą wartością i szansą dla niewidomych, gdyż wzbogaca proces kompensacji werbalnej, której istota polega na większym wykorzystaniu poznawczej funkcji mowy.
Regulacja nastroju i strategie radzenie sobie ze stresem a prokrastynacja we wczesnej dorosłości
Authors: Pisarska Agnieszka
Published: July 2020

Celem podjętej analizy było określenie związku między regulacją nastroju oraz typowymi sposobami reagowania i odczuwania w sytuacjach doświadczania silnego stresu a prokrastynacją. Przebadano 96 osób w okresie wczesnej dorosłości. W badaniach zastosowano następujące metody badawcze: do pomiaru prokrastynacji – kwestionariusz Pure Procrastination Scale; do analizy regulacji nastroju – Skale Regulacji Nastroju Bogdana Wojciszke; do oceny strategii radzenia sobie ze stresem – kwestionariusz Mini-COPE. Przeprowadzone analizy ujawniły istnienie związku między prokrastynacją a regulacją nastroju (osoby prokrastynujące częściej stosują strategie polegające na obniżaniu nastroju) oraz między prokrastynacją a ośmioma (spośród czternastu) strategiami radzenia sobie ze stresem. Wraz ze wzrostem prokrastynacji nasila się tendencja do stosowania nieadaptacyjnych stylów radzenia sobie ze stresem, w tym strategii polegającej na zaprzeczaniu istnieniu problemu oraz na zaprzestaniu działań i rezygnacji z prób osiągnięcia celu, a także strategii polegających na zajmowaniu się czymś innym i wykorzystywaniu poczucia humoru, zaabsorbowaniu pojawiającymi się nieprzyjemnymi emocjami poprzez ich wyładowanie oraz obwinianiu się. Odwrotnie proporcjonalny związek zaobserwowano między prokrastynacją a adaptacyjnymi strategiami radzenia sobie ze stresem, polegającymi na planowaniu postępowania i podejmowaniu działania w celu poprawy sytuacji. Przeprowadzona dodatkowa analiza nie ujawniła istotnych różnic między kobietami i mężczyznami w zakresie nasilenia prokrastynacji. Istotne różnice wystąpiły w zakresie dwóch wymiarów prokrastynacji: behawioralnego i decyzyjnego.
Początki bywają trudne. Zmiany rozwojowe poczucia kontroli wśród uczniów w okresie wczesnej adolescencji doświadczających transformacji systemu edukacji w Polsce

Celem artykułu było przedstawienie wyników i wniosków z badań dotyczących zmian rozwojowych poczucia kontroli wśród współczesnej młodzieży w okresie wczesnej adolescencji doświadczającej przekształceń systemu edukacji w Polsce. Analizy stanowią podsumowanie pierwszych dwóch, z zaplanowanych trzech, etapów badań podłużnych. Prezentowane wyniki odnoszą się do powtarzanego co rok pomiaru poczucia kontroli w dwóch grupach uczniów: rocznika ze szkół podstawowych, który jako pierwszy realizuje wydłużoną naukę w szkole podstawowej – w klasie szóstej i siódmej, oraz uczniów, którzy stanowią rocznik wygaszający naukę w gimnazjach – w klasie pierwszej i drugiej. Poczucie kontroli zgeneralizowane oraz w sytuacjach sukcesów i porażek zostało ustalone na podstawie Kwestionariusza do Badania Poczucia Kontroli KBPK i KBPK-R. W badaniach sprawdzono, jakie różnice wystąpiły w zakresie zmian rozwojowych poczucia kontroli między uczniami szkół podstawowych i gimnazjów. Wyniki pokazały, że na przełomie dwóch lat badań w obu grupach uczniów wzrosło wewnętrzne poczucie kontroli, jednak to uczniowie szkół podstawowych charakteryzują się istotnie wyższym wewnętrznym przypisywaniem sobie odpowiedzialności za zdarzenia, szczególnie w sytuacjach sukcesów. Dodatkowe analizy uwzględniające płeć ujawniły wzrost zgeneralizowanego poczucia kontroli u dziewcząt oraz wewnętrznej kontroli w sytuacjach porażek u chłopców z gimnazjum.

In addition, the legal effect of its creation is the introduction of an appropriate legal regime in the form of prohibitions allowed by law and the expropriation of real estate for the public purpose of its creation, which is the protection of unique natural values occurring in its territory.
Wpływ unijnej polityki klimatyczno-energetycznej oraz handlowej na realizację trwale zrównoważonej gospodarki leśnej – aspekty prawne
Authors: Leśkiewicz Katarzyna
Published: July 2020

The subject of considerations are the legal aspects of the influence of the EU climate and energy framework and trade policy on implementation of permanently sustainable forestry. Even though forestry belongs to the competences of Member States and there is no formal establishment of common forest policy in the TFEU, the new LULUCF Regulation and provisions of regulations regarding prevention of illegal timber trade prove that there is an ongoing process of subjecting forestry to the competencies of the European Union to a growing extent as well as reducing the area left to Member States. It must be stated that the platform for expansion of EU regulations on Member States’ forestry in terms of land use and timber trade – acts adopted within the trade policy and climate and energy framework – is the principle of sustainable development that derives from international legislation and is also included in the Constitution of the Republic of Poland. This principle is also the foundation for development of the beginnings of common forest policy that emerges at the verge of EU policies.

Interpretative Discretion of Judiciary and the Well-Being of the Child
Authors: Hanas Katarzyna
Published: July 2020

The well-being of the child is a common criterion in many Polish normative regulations pertaining to different branches of law. It is both a tool for the law-making and the executive bodies, employed to direct the law-applying bodies towards ensuring full protection of the child. This article is focused on analysing interpretative judicial discretion with respect to the well-being of the child as manifested in the judicial decisions of the Supreme Court and in the judgements of the Supreme Administrative Court and Constitutional Tribunal. In the course of the research, the author undertakes to determine the essence of interpretative judicial discretion in cases predominantly focused on establishing the current and postulated situation of the child with a view to ensuring the most favourable ruling for the same.
Open Axiology in Judicial Interpretation of Law and Possible Misuse of Discretion
Authors: Leszczyński Leszek
Published: July 2020

The subject of the article is to determine the extent to which the judicial interpretation of the law is affected by the use of an open axiology argument in the course of adjudication. Assuming that the use of open criteria is based primarily on the application of the legislative construction of general reference clauses, it is important to link these references to a legislative policy in which they constitute a means of deliberately extending the scope of discretionary power, derived from natural (independent of the legislator) sources. The essential function of the references is the axiological opening of findings made in all essential phases of judicial interpretation – validation, reconstruction and construction, resulting, among other things, in a change in the relationship between the roles of particular interpretation rules. This may lead to various manifestations of abuse of the interpretative discretion of judges, which in turn necessitates the search for certain remedies, among which the formation of permanent lines of jurisdiction and precedential practice, as well as the transparency of the reasoning of judgements, seems to be of the utmost importance.
