Authors: Limouni Tariq , Yaagoubi Reda , Bouziane Khalid , Guissi Khalid , Baali El Houssain
Published: June 2022

The energy demand is increasing due to population growth and economic development. To satisfy this energy demand, the use of renewable energy is essential to face global warming and the depletion of fossil fuels. Photovoltaic energy is one of the renewable energy sources, widely used by several countries over the world. The integration of PV energy into the grid brings significant benefits to the economy and environment, however, high penetration of this energy also brings some challenges to the stability of the electrical grid, due to the intermittency of solar energy. To overcome this issue, the use of a forecasting system is one of the solutions to guarantee an effective integration of PV plants in the electrical grid. In this paper, a PV power ultra short term forecasting has been done by using univariate and multivariate LSTM models. Different combinations of input variables of the models and different timesteps forecasting were tested and compared. The main aim of this work is to study the influence of the different combinations of variables on the accuracy of the LSTM models for one-step forecasting and multistep forecasting and comparing the univariate and multivariate LSTM models with MLP and CNN models  . The results show that for one step forecasting, the use of a univariate model based on historical data of PV output power is sufficient to get accurate forecasting with 28.98W in MAE compared to multivariate models that can reach 35.39W. Meanwhile, for multistep forecasting, it is mandatory to use a multivariate model that has historical data of meteorological variables and PV output power in the input of LSTM model. Moreover, The LSTM model shows great accuracy compared to MLP and CNN especially in multistep PV power forecasting.

Authors: Nugroho Dedi
Published: June 2022

Pengoperasian turbin angin terbagi atas beberapa zona operasi dengan tujuan untuk memaksimalkan kinerja turbin angin dan melindungi bilah turbin dari kerusakan saat diterpa oleh angin berkecepatan tinggi.  Pembagian zona didasarkan pada besarnya kecepatan angin.  Jika kecepatan angin berada diantara kecepatan nominal dan kecepatan cut out, maka turbin angin dapat dioperasikan pada nilai daya nominalnya dengan cara mengatur sudut pitch bilah turbin angin sedemikian rupa sehingga turbin angin dapat menghasilkan daya nominal.  Riset ini bertujuan menganalisis hubungan antara perubahan kecepatan angin dan sudut pitch bilah turbin angin untuk mendapatkan daya nominal generator sinkron 3 fasa. Metode riset dilakukan melalui pemodelan turbin angin dengan generator sinkron 3 fasa. Turbin angin dirancang memiliki kapasitas daya mekanik 34,7 kW untuk kecepatan nominal angin 8 m/s yang dapat menghasilkan daya listrik nominal 32,68 kW, 408 volt pada kecepatan generator 1500 rpm. Hasil riset memperlihatkan perubahan kecepatan angin antara 8 m/s sampai dengan 15 m/s dapat mempertahankan  kecepatan dan daya nominal generator tersebut dengan mengatur sudut  pitch bilah turbin  antara 00 sampai dengan 26,9270.

Panel surya menangkap cahaya sinar matahari diwaktu siang hari dan disimpan pada baterai setelah melalui regulator. Energi yang disimpan digunakan untuk charging baterai sepeda listrik dan peralatan sistem penyewaan sepeda.
Culture Entrenched Gender Inequality in Othello by William Shakespeare and Night of No Moon by Syed Waliullah: A Comparative Study
Authors: Kabir K.M. Wazed , Israt Kashfia
Published: June 2022

Culture of a society directly influences the pattern of behavior of the people. It is such a strong force that, people are hardly able to go and think beyond the boundary of their cultural practices. The problem begins when cultural indoctrination controls human thought process and appears to justify inhuman practices in the name of culture and tradition. This study has been done with a view to exposing the gender-based inequality prevailing in the society which is nurtured by culture. In doing so Othello by William Shakespeare and Night of No Moon by Syed Waliullah, two great pieces of literary works have been picked. Both of the literary pieces depict unequal treatment of the women in the society. Although, two of them are composed in different contexts, yet there are similarities in terms of treatment of females in the society. In both Othello and Night of No Moon the fate of women is decided by the men and the whole societal system fuels the unjust action. The authors draw real life characters to show how the females become victims in the hand of social organizations formed and dominated by men. This study explores through the characters and plots of the two texts and intends to see the facts from a feminist point of view to analyze behavior of people. Therefore, we observe the condition of women of the society, who are considered as ‘the weaker sex', and continuously dominated, suppressed and victimized by culturally motivated men. Thus, we have put our logical argument drawing evidences from the literary texts to establish that, Culture of a society substantially contributes to constitute patriarchal mindset among the people of the society which results in treating women as so called ‘Second sex'.
On legal income targets for agriculture in Switzerland and in the European Union
Authors: Richli Paul
Published: June 2022

This article deals with the legislation regulating income from agriculture in Switzerland and in the EU. The provision of Article 5(1) of the Swiss Agriculture Act treats agricultural income similarly to incomes from other branches of economy This regulation, however, does not ensure farmers any income guarantee and is not enforceable in courts. The Common Agricultural Policy provisions are more general and also unenforceable. Article 39(1)(b) of the TFEU refers to a “fair standard of living for the agricultural community.” While the average agricultural income in Switzerland in the period 1997–1999 was only 52% of the comparative income, this percentage was already 66% by the period 2017–2019. The agricultural policy 22+ seeks to reduce this income gap even more. In the EU, the average income from agricultural activity increased from 32% in 2009 to 49% in 2017 of the comparative income from other branches and the new CAP policy 2022–2025 also seeks to reduce this income gap further. As can be seen, when compared to income in the economy as a whole, farmers’ income in Switzerland is substantially higher than in the EU. However, both Switzerland and the EU must undertake further efforts to comply with the current legal requirements to support legal income targets in agriculture.
La contratación agroalimentaria tras las medidas de la nueva Ley 16/2021 de 14 de diciembre para mejorar el funcionamiento de la cadena alimentaria
Authors: Sánchez Hernández Ángel
Published: June 2022

Los desequilibrios en la cadena alimentaria debidos, entre otros factores, a las diferencias en el poder de negociación entre los productores agrícolas y otros operadores más poderosos de la cadena de suministro, conducen a la imposición de precios y prácticas comerciales desventajosas a los agricultores y ganaderos (que son los actores más vulnerables de la cadena). La Ley 12/2013 y sus sucesivas modificaciones pretenden eliminar estos importantes desequilibrios y mejorar la posición de la parte contractual más débil (los productores primarios) en la cadena agroalimentaria, asegurando así a los agricultores y ganaderos un precio de venta (determinado en el correspondiente contrato alimentario) que estará por encima del coste real de producción, de forma que obtengan un margen de beneficio que les permita mantenerse y continuar con su actividad agraria.

Społeczne i polityczne uwarunkowania nierówności oświatowych w Polsce. Geneza – rozmiary – polityka bezczynności
Authors: Pilch Tadeusz
Published: June 2022

Opracowanie poświęcone jest zjawisku nierówności oświatowych, w szczególności między miastem a wsią, które traktuję jako podstawowe źródło wszelkiej nierówności w nowoczesnym społeczeństwie. Dostęp do kształcenia i udział w systemie oświaty jest głównym źródłem społecznego awansu człowieka we współczesnym świecie. Dostęp do szkolnictwa reguluje prawo narodowe i traktaty międzynarodowe. Udział w kształceniu warunkowany był w przeszłości okolicznościami społecznymi i obyczajowymi (np. nauka kobiet, polityka stanowa w Rzeczpospolitej szlacheckiej), współcześnie natomiast jest zależny głównie od warunków ekonomicznych. Wszelkie wskaźniki mierzące poziom rozwoju i warunków materialnych mieszkańców miasta i wsi ukazują głębokie zróżnicowanie sytuacji ekonomicznej między tymi dwoma środowiskami, zawsze na niekorzyść wsi. Genezy tych nierówności upatrywać należy zarówno w uwarunkowaniach historycznych, które dla wsi były wręcz tragiczne, w postaci jednej z najokrutniejszych, opresyjnych form pańszczyzny, jak również w czasach współczesnych, które na wieś nałożyły bezwzględne serwituty, np. tzw. obowiązkowych dostaw, odbierając rolnikom wszelki kapitał rozwojowy. I ta nieprzyjazna polityka ekonomiczna wobec wsi jest kontynuowana przez aktualne władze, które tworząc pozory „dobroczynności” finansowej w postaci spektakularnych, jednorazowych gestów wyłączyły wieś z procesu awansu cywilizacyjnego, którego przykładem była w czasach realnego socjalizmu np. elektryfikacja wsi. Dziś symptomami upośledzenia ekonomicznego, a tym samym i kulturowego jest m.in. wykluczenie komunikacyjne; likwidacja infrastruktury kulturalnej; wykluczenie dziecka wiejskiego z wszelkich zajęć rozwojowych, pozaszkolnych – co automatycznie skazuje je na intelektualną drugorzędność; wzrost kosztów kształcenia, komercyjnych opłat za internaty, bursy; beztroska rządu o stan zdrowia dzieci wiejskich. Strategia rozwoju, mityczny ład gospodarczy nie tworzą żadnych złudzeń, że awans ekonomiczny i kulturowy wsi jest przedmiotem troski rządu o równomierny rozwój wszystkich środowisk, a szczególnie środowisk upośledzonych. W zakresie awansu oświatowego wsi, w świetle ogłaszanych deklaracji ministerstwa edukacji, trzeba porzucić wszelkie nadzieje. Blokada społecznego charakteru szkoły, wyjęcie jej spod wpływów samorządu i wspólnoty rodziców, groteskowe deklaracje programowych celów kształcenia, wszechwładza kuratorów, która nigdy w historii nie dała dobrych owoców, odbierają nadzieję na szanse awansu i równości.

Traumatic memory and the abuse of child rights in Things Fall Apart
Authors: Onuoha Onyekachi Peter
Published: June 2022

Neglect is a form of child abuse it is the failure of parents to redeem their obligation towards their children. In the novel titled: Things Fall Apart (henceforth TFA) written by Chinua Achebe, the protago- nist called Okonkwo suffers parental neglect, which of course led to his ultimate downfall. Okonkwo’s father, Unoka failed to give adequate parental care to his son as portrayed by Achebe in the novel and that parental gap acted as an inertia in Okonkwo’s tragic end. Through the application of trauma theory, this study examines childhood trauma and how it conditions the character in adulthood in African novel. The study adopts the discursive approach to textual analysis and observes that toxic masculinity is a product of poor parenting resulting in childhood traumatic experiences that culminate into the use of force, exploitation and victimization cum abuse of children and women as depicted in TFA. The study submits that Okonkwo’s childhood trauma in TFA is an unexplored fear that influences and conditions him even unto adulthood. This study opines that Okonkwo’s trauma is a site for extended traumatization of kin and that Okonkwo’s unhealed trauma finds expression in his survival antics. The study concludes that Okonkwo is a trauma patient and his success and failure in Umuofia is a product of trauma.

Published: June 2022

Objectives

Accurate measurement of serum folate is essential for the diagnosis and management of various disorders. This study aims to investigate the between-method differences of four immunoassays and a rapid isotope-dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) method.

Methods

Roche Cobas (USA), Abbott Alinity i2000 (USA), Beckman Coulter Access (USA), Mindray CL-6000i (China), and the ID-LC-MS/MS method were compared using 46 human serum samples. The results were analysed by Passing–Bablok regressions and Bland–Altman plots. A bias of 13.31% based on biological variation was used as the bias criterion.

Results

All the within-run and total coefficients of variation (CVs) met the specification. The folate concentrations determined by all the assays were significantly different (p=0.0028). All assays had correlation coefficients over 0.97 with each other. The 95% confidence intervals (CIs) for the slope seldom contained 1 and few 95% CIs for the intercept contained 0 in the regression equations. Compared to ID-LC-MS/MS, the biases of all assays ranged from −20.91 to 13.56 nmol/L, and the mean relative biases ranged from −9.85 to 40.33%. The predicted mean relative biases at the medical decision levels rarely met the criterion.

Conclusions

Assays for serum folate had good correlations with each other but lacked good agreement. The accuracy and consistency of assays for serum folate should be measured and assessed routinely. Standardization work to improve the accuracy of serum folate assays, such as the extension of traceability to reference methods or materials, calibration standardization efforts, and assay-adjusted cut-offs should be promoted.
Assessing verbal interaction: towards European harmonization. Insights from the co-operation between Spanish and French language exams for Higher Education (CertAcles/CLES)
Authors: Zabala Delgado Julia , Rouveyrol Laurent
Published: June 2022

Verbal interaction has been the subject of a growing interest among language professionals in Europe since the CEFR was published in 2001; in linguistics, verbal interaction has long been studied. In the Bakhtinian approach, it is even considered “the fundamental reality of language”. All types of interaction share the fact that they are dynamically co-constructed by participants. How then can we assess or certify interactional competence on an individual basis when dynamic instability prevails? What criteria can be defined in order to deconstruct interactional competence into specific operational criteria, if interaction is intrinsically multidimensional? These are the questions that we address in this paper. To do so, this paper presents the insights gained as a result of the co-operation between two certification systems: CertAcles (Spain) and CLES (France), both belonging to NULTE (Network of University Language Testers in Europe). These certification systems have agreed to collaborate extensively, sharing their constructs and assessment routines. As a result, CertAcles is shifting towards more contextualized tasks and CLES is considering adopting descriptive assessment scales for interaction (C1 level). We hope to demonstrate that the materialization of scientific collaboration of this kind can help improve individual systems.
Critical incidents as a window into simple language management
Authors: Sieglová Dagmar
Published: June 2022

Language learning is a life-long process. In a world that connects people across nations through study, work, travel and socializing, new chances and challenges arise, intensifying a need to improve modern foreign language skills. The aim of language education, therefore, should not be limited to providing mere language instruction but it should also involve the development of learner autonomy so that students are equipped with strategies, methods, and approaches for managing their language development over the course of their whole lives. Higher Education Institution (HEI) teaching practices need to react to this reality through their teaching approaches and methodologies. The following study conducted with ŠKODA AUTO University presents an analysis of the current students’ simple language management (LM) process, which reveals their language learning attitudes, behaviors and ‘acts toward’ language. Data were collected between 2017 and 2020 from students’ written narratives describing and analyzing critical incidents (CI) that reflect the learning strategies the students adopt, the study styles they use, motivation for learning, as well as the actions they plan and conduct. As a result, these findings form the basis of a deeper understanding of the language teaching process, which in turn enhances language education methodology.
Self-access learning of English intonation with speech software: examining learners’ perceptions with a focus on their concerns and negative comments
Authors: Tsang Art
Published: June 2022

Language laboratories exist in many language centres across the globe. Situated in the popularity of self-access and computer-assisted language learning in the present era, the study investigated tertiary-level English as a foreign language (EFL) learners’ general and, particularly, negative views of speech analysis software. Two hundred and eighty intermediate-level (CEFR B1 and B2 levels) EFL participants completed trial sessions with some free speech software in which they listened to and recorded utterances to practise English intonation at a language laboratory in Hong Kong. Each participant was observed during the session, completed a questionnaire, and attended a brief post-questionnaire interview after the session. Both quantitative and qualitative data were collected. The results showed that learning with this kind of software was perceived generally positively in relation to language enhancement and self-access learning. However, from the qualitative data collected about their negative views and concerns, three themes emerged: absence of a teacher, an interaction-less environment, and the little value of graphic outputs. This article concludes with a discussion of these findings and implications for language educators and researchers in self-access and computer-assisted language learning, which are in vogue globally nowadays. Suggestions for addressing learners’ negative views and comments, which have not received much attention among stakeholders, are also provided.
Native peers as mediators and experts in language learning in Higher Education
Authors: Kotkavuori Suvi , Hahl Kaisa , Hilden Raili
Published: June 2022

This qualitative study explores how native peers as teaching assistants can support language learning in Higher Education. The data of five semi-structured group interviews of 15 teaching assistants in total were analysed thematically. The results indicate that the assistants embraced multiple roles during the programme and within the lessons. However, in the role of a peer student who collaborated on an equal level with the learners, they could best facilitate learning and communication. As native speakers, they complemented the teacher’s expertise by their regional and up-to-date cultural and linguistic knowledge. This article supports a wide view of mediation adopted by the CEFR Companion Volume and focuses on its two mediation activities. The so-called didactic triangle was used to illustrate how native peers mediated between the teacher, the student and the subject to facilitate the language learning process. The assistants acted as mediators in different ways, interculturally and pedagogically. Nevertheless, a few assistants experienced challenges when assisting at lower CEFR levels. Thus, it is essential to discuss roles and expectations as well as the process together with the teachers, the students and the assistants.
Jóvenes bachilleres durante la COVID-19. ¿Nativos digitales?

Published: June 2022

A partir del surgimiento de la pandemia por COVID-19 generada por el virus del SARS-CoV-2, la población escolar mexicana fue confinada en su domicilio para continuar su ciclo escolar a través de la virtualidad en un formato en línea. Este artículo, derivado de un proyecto de investigación institucional, tiene por objetivo mostrar los problemas a los que se enfrentan estudiantes de un bachillerato tecnológico en México, relacionados a su carencia de competencias y habilidades digitales para integrarse a esta “escolarización remota emergente”, lo cual, aunado a desigualdades en el acceso al equipamiento y conectividad no les permite integrarse a dicha modalidad como nativos o migrantes digitales, sino en condición de desplazados digitales. La población escolar encuestada es una muestra no probabilística, lo que impide generalizar resultados, mismos que se obtuvieron mediante la encuesta “Jóvenes bachilleres y pandemia”, donde se exploraron las dificultades que enfrentan, sus emociones experimentadas tanto por el confinamiento en sí, como por el formato de trabajo actual. Entre los hallazgos, se encontró que los estudiantes a pesar de pertenecer a un bachillerato tecnológico no han adquirido y/o desarrollado competencias digitales para afrontar una educación virtual. El proyecto del que deriva este artículo se desarrolla en un contexto local en el momento mismo del fenómeno, por tanto, le confiere un rasgo coyuntural.

Published: June 2022

WHO recommend to associate a proper dose of movement with healthy and balanced diet, also in elderly. Promoting healthy lifestyles and adopting healthy habits can lead to a successful aging. The Mediterranean diet model is considered the gold standard nutritional treatment in some Non Communicable Diseases and the evaluation of adherence to this diet becomes essential to study the lifestyle of the population in order to prevent the risk of onset of age-related chronic diseases. In order to implement appropriate interventions for successful aging and to prevent functional alterations affecting the people autonomy in Activities of Daily Living, the LIFestyle of the Elderly in Umbria Population Project (LIFEUP) was promoted in 2018, in Italy. 36 subjects were invited to fill out self-report questionnaires used to assess health status and quality of life (EuroQol), physical activity levels (IPAQ) and Mediterranean diet adherence (MED Diet Score). Anthropometric variables (height, BMI), body composition and functional capacities (through Senior Fitness Test battery) were studied. We observed a situation of overweight (average BMI=27.4) with fat mass=30.45% and low total body water 47.64%), with a medium adherence to the Mediterranean diet (Score=7.19). Furthermore, we noted a good health status perceived (71,14/100), and acceptable physical activity levels (36.55 MET/h/week), and good functional capacities (2 minutes steps average=86.73; chair stands average=14.09; 8-foot up and go test average=6.47 sec.), according to international guidelines and standard ranges for this age. This pilot study gave an overview of a small group of the elderly Umbrian population to implement prevention and health promotion plans among the elderly.
Promoting active lifestyles in schools. Effect of school day on daily physical activity levels
Authors: Varela-Garrote Lara , Carretero-García Miriam , Fraguela-Vale Raúl , Losada-Puente Luisa
Published: June 2022

Introduction: The effect of school day is a major factor in everyday rhythms during childhood and adolescence. The relevance of Physical Activity (PA) in school-aged children raises the need to: (a) analyse whether Primary School pupils achieve the recommended levels of daily PA; (b) find out the impact of school day and, specifically, Physical Education (PE) classes on levels of PA compared to weekends; and (c) explore the differences according to sex in daily PA at these ages. Method: A cross-sectional study was carried out, using a sample of 126 participants (aged 10.2±0.48 years; 51.6% girls, 48.4% boys) from primary schools. Data on the steps taken by pupils during a week were recorded with an ADXK362 three-axis accelerometer integrated into a wristband. Descriptive (means and standard deviation) and inferential analyses (Student’s T-Test) were performed, assuming a 95% confidence interval (p<0.05). The magnitude of the difference was quantified with power (1-β), α=0.05 (bilateral). Results: The average of steps was lower than the minimum recommended, revealing a weekly pattern in which, the most active children were so throughout the week and vice versa. Significant variations were found depending on the days of the week (r=0.40, p<0.001, d= 0.63) or whether they had PE classes (r=0.65, p<0.001, d= 0.79). School day contributed significantly to greater activity and families were less physically active on weekends (t=6.62, p<0.001, d=0.70). Girls had a lower level of PA than boys, and more difficulty reaching the recommended levels of daily PA (t=-4.05, p<0.001, d=0.96), except on weekends. Conclusion: Pupils do not reach the minimum recommended daily steps for their age, with a well-established gender gap in favour of boys. School day (especially when PE is taught) increases their daily PA more than at weekends.
Effect of Physical Exercise on Adiposity and Physical Fitness in Middle Age Men with Different Body Mass
Authors: Bunc Václav
Published: June 2022

Purpose: Overweight and/or obesity is a growing problem over the world. Alongside a range of health problems associated with increased body mass (BM) – adiposity and reducing of fitness level it is an important limiting factor for realization of regular physical exercise and quality of life. Therefore, the aim of our study was to verify the effect of physical intervention based on walking in men of middle age with different weight status with minimal changes in their eating habits. Material and Methods: Study was carried out in 25 middle age men with normal BM (mean age=43.7±3.6 years; BM=78.3±3.9 kg; height=177.5±4.6 cm; %BF=22.1±2.1 %, VO 2peak=33.2±3.1 ml/kg.min), 26 overweight men (42.0±2.9; 89.9±3.1; 178.1±4.0; 27.9±2.2; 30.2±3.9) and 18 obese men (43.8±3.0; 97.4±4.6; 178.3±3.2; 33.1±3.4; 24.1±4.2). All these subjects were without regularly movement training before the starting of intervention. Body composition was assessed by bioimpedance method using prediction equations that are valid for the Czech men population, functional variables were assessed on a treadmill. Results: The energy content per kg BM of weekly exercise for subjects with normal BM was 20.40±4.51 kcal/kg (13.4 – 20.4 kcal/kg), in overweight 20.36±3.00 kcal/kg (15.4 – 24.5), and in obese 20.33±3.39 kcal/kg (17.6 – 24.0). Reduction in %BF ranged from 9.4±2.7 % in obese to 8.6±2.1 % in normal BM of starting value, ECM/BCM relationship was decreased from 11.0±1.4 % in subjects with normal BM to 12.2±1.9 % in obese, and in VO 2peak increased from 10.3±2.2 % in normal BM to 12.7±2.6 % in obese. In men differing in BM are absolute changes in adiposity and aerobic fitness like a result of imposed movement intervention substantively and statistically significant (p<0.05, d≥0.05). On the contrary, differences in percentages of pre-intervention values are non-significant. Conclusion: Exercise program with a similar energy content, form and intensity causes the similar changes in adiposity and in functional performance in middle age men, differing in BM. Movement intervention based on walking reduces body weight and at the same time improves the morphological preconditions for physical activity.
The player’s penal responsibility for the actions of violence in sports: legal analysis in context of United Arab Emirates law

Published: June 2022

This study deals with the issue of the player’s penal responsibility for acts of violence in sports; it aims at briefing the important legal issues related to this subject and clarifying the position of the UAE legislator on a player’s criminal liability for sports injuries and acts of violence in sports by researching the legal framework for sports injuries and sports accidents that occur during sports competitions. The study concluded that to be exempt from criminal liability in sports competitions, the game must be one of the games recognized by sports games laws, it must have recognized rules, and the acts of violence committed during the match must not violate the game rules. Also, the UAE has included sports insurance in certain sports activities as a club obligation, so any player registered with the relevant association is not allowed to participate in sports activities managed by the union unless this player is insured under a contract of insurance that includes the risks of death, permanent or temporary disability, sports injury, and medical expenses. The study suggests that the UAE legislature should pass a sports criminal law criminalizing the use of stimulants in sports.

Published: June 2022

The aim of this study is to assess the development of fair play soft skills by means of validated tools in the native language for the target group of adolescents. Fair Play in Physical Education Questionnaire (FPQ-PE) was completed by 450 secondary school students from the 9–14 age group, 490 secondary school students aged 9–13 years and 725 students aged 18–21 years. Linguistic validation was provided. Psychometric properties were assessed by exploratory and confirmatory factor analysis. The final version of the translation was the result of review process according to consultation with translators, redactor of scientific literature, and results of pilot testing. The general internal consistency was 0.861, indicating the good consistency of the instrument. In terms of test-retest validity of FPQ-PE, scores at first and second-time points have no significant differences. The CFA indicated a good model fit (χ2/df = 2.15, RMSEA = 0.074, SRMR = 0.058, CFI = 0.949). The results showed good test-retest reliability (Spearman’s rho = 0.80, p < 0.01). In the age group 9–14 years old males had higher level of antisocial skills, but also a higher index according to “Convention” scale. For another group (18–21 years old) females had better prosocial skills according to results of “Respect towards teammates,” “Gamesmanship,” and “Cheating” scales.

Do perspective-sensitive anaphors and subjective adjectives exhibit perspectival uniformity? An experimental investigation
Authors: Kaiser Elsi
Published: June 2022

Many kinds of linguistic expressions are perspective-sensitive, including predicates of personal taste and some anaphoric forms. This paper reports three experiments testing sentences like “Nora told/heard from Kimberly about the frightening photograph of her/herself”, with two perspective-sensitive elements. The studies investigate how perspectival factors – in particular, a referent’s status as a source or perceiver of information – guide interpretation of these two types of expressions and whether participants’ interpretation of whose opinion is expressed by a subjective adjective is linked to their interpretation of who is the antecedent of the reflexive or pronoun. The results replicate and extend earlier findings concerning the source/perceiver biases of reflexives and pronouns in picture-NPs, and also reveal a clear preference to interpret the attitude holder of PPTs as the individual who is the source of information (subject of ‘told’, object of ‘heard from’). However, the results fail to provide clear evidence for a systematic link between interpretation of the attitude-holders of PPTs on the one hand, and the antecedent of the pronouns and reflexives in picture-NPs on the other. Consequences of these results for theories of PPTs, anaphor resolution and perspective-shifting are discussed.

Resistance spot welding (RSW) of dissimilar metals is an emerging trend in automobile industries in the manufacture of passenger-vehicle bodies. It provides the material characteristics and advantages of both metals. In this research work, the influence of heat addition and maximum interface temperature in the RSW of austenitic stainless-steel sheets (AISI 304 and AISI 316L) is investigated by welding the specimens at various levels of welding current and weld time. The ultimate strength of the spot-welded joints is analyzed to evaluate the amount of heat utilization and the quality of spot welds, finite-element analysis, and macrostructural evaluations. The thermal distribution profile and stress-strain analysis on the welded specimens are carried out with the 3D finite-element model developed using ABAQUS V6.6 software through incremental electro-thermal-structural analysis. A maximum tensile shear failure strength of 253 MPa was obtained with a nugget diameter 6.55 mm and the heat utilization being 59.69 %.

Published: June 2022

Este trabalho investiga a resistência mecânica de Blocos de Terra Comprimida (BTC) estabilizados com Cinza de Bagaço de Cana-de-açúcar (CBC) em substituição parcial ao cimento Portland, com o objetivo de valorizar os materiais de construção locais e a contribuir para a redução de custos de moradias especialmente em áreas rurais. Neste contexto, uma série de blocos foram fabricados usando solo, 10% de cimento em peso do solo (T1) e substituições do cimento por 10% (T2), 20% (T3) e 30% (T4) de cinza de bagaço de cana-de-açúcar, compactados com uma energia de 3,98 kg/cm². A resistência à compressão dos blocos foi avaliada aos 14 dias de idade. Os resultados demonstram que a energia de compactação adotada de 3,98 kg/cm² foi o suficiente para obter blocos com acabamento liso em todas as faces e uma boa uniformidade ao longo do comprimento, largura e profundidade. Todos os tratamentos apresentaram excelente resistência à compressão com valores superiores ao exigido pela norma brasileira NBR 8491 (2012) de 2,00 MPa, com resultados de 3,98, 3,63, 3,30 e 3,51 MPa para os traços T1, T2, T3 e T4, respectivamente. De maneira geral, os resultados mostram a viabilidade técnica da fabricação de blocos alternativos para construção de alvenaria utilizando solos naturais estabilizados com cinza de bagaço de cana-de-açúcar contribuindo com construção de moradias seguras, eficientes e ambientalmente corretas.

Published: June 2022

A indústria da construção civil é um importante setor para a economia do Brasil. Contudo, seu crescimento segue atrelado ao aumento da geração de resíduos advindos da sua produção e da demolição de edificações anteriores. O crescimento e transformação das cidades trouxeram preocupações para o setor, em função do impacto ambiental negativo causado pelos resíduos gerados. É fundamental que tal avanço não cause prejuízos ao meio ambiente, e para isso, uma possível solução pode ser a utilização de princípios como da Lean Construction, que tem como um dos objetivos reduzir o desperdício da operação produtiva, por meio do uso de tecnologia e novas soluções para o reuso dos resíduos gerados. O objetivo do estudo foi descrever o manejo de resíduos provenientes da obra de infraestrutura do Colégio Militar de São Paulo (CMSP). Trata-se de uma pesquisa qualitativa, por meio de estudo de caso. Foi possível evidenciar que o planejamento para a gestão dos resíduos contemplou uma análise quanto a demolição, redução, reutilização, reciclagem e destinação final dos resíduos, bem como do reuso de materiais e dos recursos financeiros necessários. Identificou-se que a aplicação dos princípios da Lean Construction, permitiu reduzir os desperdícios e melhorar o desempenho da obra, tais ações reduziram o custo de transporte da destinação final dos RCC em 72%. Este estudo realizado em uma obra do CMSP poderá ser replicado em outras obras do mesmo segmento, fomentar novas pesquisas bem como contribuir para a mitigação dos impactos ambientais negativos advindos dos RCC.

O termo sustentabilidade está em evidência global. É tema inafastável quando se discute agronegócios, produtividade, preservação da fauna, da flora, clima, uso dos recursos naturais, descarte de resíduos, entre outros. No entanto, formas de se melhorar tal cenário se mostram através do emprego da educação ambiental e da conscientização das comunidades. Este trabalho, em específico, teve como objetivo avaliar os aspectos sociais, econômicos e ambientais de propriedades rurais do Município de Floreal - SP, bem como a percepção dos agropecuaristas. Foram aplicados questionários junto a 40 produtores contendo 26 questões com diversas respostas, abordando questões ambientais e como são tratadas. Avaliou-se fatores como: composição familiar, renda, produção, assistência e uso de tecnologias. Estimou-se também a produção agrícola e animal, além de fatores consequentes destas atividades, como o descarte do lixo, destino do esgoto, conservação do solo e de matas ciliares. A partir das respostas, revelaram-se problemas, como exemplo: destino incorreto do lixo, do esgoto, entre outros fatores. Outro fator de suma importância, são as consequências, como contaminação do meio ambiente, disseminação de agentes de enfermidades às pessoas presentes nas propriedades. Ao final, verificou-se uma carência de programas de educação ambiental que proporcionaria ao produtor rural uma visão de equilíbrio de manejo de sua atividade, sem descuidar da segurança de sua própria saúde e do meio em que vive.
