A alimentação fitness: corpo e comida na contemporaneidade
Authors: Costa Neuza Cristina Gomes , Abonizio Juliana
Published: April 2023

Dentre a diversidade de práticas alimentares e crenças nutricionais que existem na contemporaneidade, visamos a explorar a relação entre uma dieta e uma forma corporal que se tornou conhecida como alimentação fitness, com a finalidade de compreender as particularidades dessa recente e crescente configuração da alimentação contemporânea. Para atingir esse objetivo, propusemos uma pesquisa qualitativa, com utilização de entrevistas a partir de dois critérios: a autoidentificação e a evidência do formato corporal que caracteriza o pertencimento ao estilo de vida correspondente. Para maior compreensão do fenômeno, também realizamos observação participante em dois locais frequentados pelos sujeitos da análise. Como resultados, foi possível identificar o uso de discursos científicos para defender nutrientes, eficácia de um padrão alimentar que inclui produtos, modos de preparo e horários, entre outras variáveis consideradas essenciais para obter o formato do corpo desejado – hipertrofiado e com baixo índice de gordura. Tal corpo, apesar de percebido como o produto de uma responsabilidade individual, é amparado em discursos de várias modalidades de profissionais da saúde, da mídia e de outros membros que adotam o mesmo estilo de vida. Também pudemos aferir, contudo, que a mudança dos hábitos alimentares para inserção e aceitação no universo fitness afeta a sociabilidade dos sujeitos, em especial no espaço familiar, mas também a entrada e a permanência em novos grupos de pares, afastando os sujeitos de grupos antigos.

Published: April 2023

In this paper, an automated high-accuracy acoustic-based drone detection
and classification system using a frequency feature extraction method
based on the Prony algorithm is proposed. To show the efficiency of the
proposed method, the accuracy of detection and classification of the
suggested method is evaluated by an experimental dataset composed of
recorded drone audio in a natural environment and under different
conditions. Results show more than 97.7% and 93.6% accuracy for
detection and classification, respectively, while using typical audio
features like MFCCs, GTCCs, and FFT provide less than 78.6% accuracy
for classification.
A Psychological Stress Biomarker in Pregnant Women: Ultra-short-term Heart Rate Variability
Authors: Xie Weiyi , Wang Man , Li Huiyun , Wang Pingqiao , Emery Clifton , Ng Siuman
Published: April 2023

Prenatal maternal psychological stress is common in pregnant women.
Heart rate variability (HRV) has recently become considered to be a
potentially reliable stress biomarker in adults. Methods:In the current
study, we evaluated ultra-short-term HRV (1-minute measurement) as a
stress indicator among pregnant women (N = 230) by examining the
association between HRV parameters and self-reported prenatal maternal
psychological stress (emotional distress, and anxiety). Results:
Prenatal emotional distress was associated with a lower root mean square
of successive differences between normal heartbeats (RMSSD), pNN50, SDNN
Index, and low-frequency power (LF) among healthy pregnant women
participants. In addition, prenatal anxiety was related to a
lower-than-normal high-frequency power (HF) and elevated LF/HF values.
For high-risk pregnant women (with reported scores greater than or equal
to the 90th percentile), prenatal emotional distress and anxiety were
not significantly correlated with any HRV indicators. Conclusions: Low
HRV (associated with reduced parasympathetic activity) can serve as an
efficient biomarker for psychological stress in healthy pregnant women.
However, the HRV indicators in pregnant women with a high risk of
psychological stress problems may be affected by other mental or
physical problems, thus decreasing the biomarker’s efficiency in
predicting their prenatal psychological stress.
Perceptions of PrEP on Twitter: A Theoretically Guided Content Analysis on the Behavioral Determinants of PrEP Uptake
Authors: Calabrese Christopher , Zhang Jingwen , Yu Xudong
Published: April 2023

HIV pre-exposure prophylaxis (PrEP) is a preventative strategy that involves taking a daily, oral medication to reduce the risk of contracting HIV. Advancements in recent years may have changed the ways in which PrEP is discussed in public discourse, and the use of social media for openly discussing and disseminating PrEP-related promotion messages has been understudied. Thus, this study focuses on understanding the current discourse surrounding PrEP on Twitter. Through a quantitative content analysis, this study examined the messaging, sources, and sentiments and emotions expressed in PrEP-related tweets posted from April 2019 to April 2020, six months before and after the FDA approval of Descovy for PrEP. After the approval of Descovy, there was a significant decrease in tweets relating to barriers for using PrEP; further, informational tweets about PrEP significantly increased. However, a large proportion of tweets still discussed barriers (29.9%), suggesting that addressing barriers to PrEP remains a top priority for promoting PrEP uptake. A lack of tweets discussing individual attitudes, norms, and behavioral control about PrEP may suggest that the social media discourse is not covering the important aspects of behavioral determinants for PrEP adoption. Health communication researchers can focus on developing message strategies that target these theoretical constructs to promote the adoption of PrEP among key target populations.
A resins-neutralization coupled route for the treatment of stainless-steel pickling effluent: A research study
Authors: Bhadrinarayanan Lalgudi , Babu Chinthalacheruvu
Published: April 2023

One of the major environmental problems caused by stainless-steel industries is the liquid effluents generated during the production processes. It contains a high concentration of metal ions such as Fe (III), Cr (III), Cr (VI), and Ni (II) in HF and HNO3 mixture, oil, and rinse wastewater. The used pickling waste stream has a pH of 0.5 and Total Dissolved Salts (TDS) of 520g/L with a density of 1.20g/CC. The present work focused on recycling pickling effluent by combining filtration, resins, and neutralization to remove metal ions efficiently and F- greater than 99.5%. To remove TDS, laboratory experiments were performed using micro and ultra-filters with a membrane area 0.2m2. Cr (VI) was removed using TulsionFSMP 6301 resin and desorption using NaNO3 and subsequent conversion into Na2Cr2O7 as a by-product. For neutralization, Ca(OH)2 and NaOH were used to precipitate metal ions, and the resulting filtrate was polished using ZrOCl2 to remove F- to 0.12 mg/L effectively. The nitrate was recovered as NaNO3. Adsorption isotherm and kinetic studies were utilized for Cr (VI) from experimental data, and a process flow diagram was developed, which can eventually be tested on a larger scale.

Published: April 2023

OBJECTIVE

To simulate economic outcomes for individuals with diabetic macular edema (DME) and estimate the economic value of direct and indirect benefits associated with DME treatment.

RESEARCH DESIGN AND METHODS

Our study pairs individual and cohort analyses to demonstrate the value of treatment for DME. We used a microsimulation model to simulate self-reported vision (SRV) and economic outcomes for individuals with DME. Four scenarios derived from clinical trial data were simulated and compared for a lifetime horizon: untreated, anti-VEGF therapy, laser, and steroid. To quantify the relative magnitude of costs and benefits of DME treatment in the U.S., we used a cohort-level analysis based on real-world treatment parameters derived from published data.

RESULTS

In the model, excellent/good SRV roughly corresponded to 20/40 or better visual acuity. A representative 51-year-old treated for DME would spend 30–35% additional years with excellent/good SRV and 29–32% fewer years with fair/poor SRV relative to being untreated. A treated individual would experience 4–5% greater life expectancy and 9–13% more quality-adjusted life-years. Indirect benefits from treatment included 6–9% more years working, 12–19% greater lifetime earnings, and 8–16% fewer years with disability. For the U.S. DME cohort (1.1. million people), total direct benefit was $63.0 billion over 20 years, and total indirect benefit was $4.8 billion. Net value (benefit − cost) of treatment ranged from $28.1 billion to $52.8 billion.

CONCLUSIONS

Treatment for DME provides economic value to patients and society through improved vision, life expectancy, and quality of life and indirectly through improved employment and disability outcomes.
How Bulky of Base Adducts can be Responsible for Clastogenicity rather than Mutagenicity?
Authors: Sasaki Yu F
Published: April 2023

Two types of TK mutants are induced by genotoxic factors; normally growing (NG) TK mutants due to point mutations of targeted TK locus, and slowly growing (SG) mutants due to gross structural changes involving the growth-regulating gene outside targeted TK locus. In this study, human lymphoblstoid WTK1 cells were used to consider how bulky n- alkylated bases can induce SG mutants. For this purpose, n-alkyl methanesulfonates (AMS) having an n-alkyl group with 3-7 carbons [n-propy methanesulfonate (PMS), n-butyl methanesulfonate (BMS), n-pentyl methanesulfonate (PeMS), n- hexyl methanesulfonate (HexMS), and heptyl methanesulfonate(HepMS)] were synthesized. n-alkyl methanesulfonates having n-alkyl groups with 1-7 carbons induced NG mutants, but n-alkyl methanesulfonates having n-alkyl groups with ≥4 carbons but not with ≤3 carbons induced SG mutants. n-Alkyl methanesulfonates having n-Alkyl groups with ≥4 carbons have been shown to induce bulky adducts that cause disturbances to the helical DNA structure and are removed by nucleotide excision repair. It could be considered that n-alkyl groups with ≥4 carbons causing disturbances to the helical DNA structure induce SG mutants to result in clastogenicity rather than mutagenicity.
Pienryhmän yhteiskirjoittamisen prosessin vaiheet ja vuorovaikutus viidennen luokan historian tunnilla
Authors: Sopanen Sanni , Juvonen Riitta
Published: April 2023

Artikkelissa tarkasteltiin vuorovaikutuksen näkökulmasta, miten tietotekstiä laaditaan yhdessä pienryhmässä alakoulun historian oppitunnilla. Tutkimusaineisto koostui kolmen 5.-luokkalaisen oppilaan videoidusta pienryhmätyöskentelystä. Tutkimuksessa analysoitiin, miten yhdessä kirjoittamisen prosessi pienryhmässä rakentui ja millaisia kielellisen vuorovaikutuksen piirteitä siinä esiintyi. Yhdessä kirjoittamisen prosessia lähestyttiin diskurssianalyyttisestä näkökulmasta oppilaiden tekemien kielellisten aloitteiden kautta. Yhdessä kirjoittaminen ilmeni syklisenä prosessina, joka rakentui toistuvista työvaiheista: tiedonhausta, kirjoittamisen suunnittelusta ja kirjoittamisesta. Lisäksi kirjoitusprosessin työvaiheiden lomassa esiintyi työskentelyn säätelyä. Kielelliset aloitteet ja niistä kehkeytyvä vuorovaikutus erottivat vaiheita toisistaan, mutta toisaalta niillä rakennettiin ja ylläpidettiin kunkin vaiheen toimintaa. Tutkimuksessa havaittiin kirjoitusprosessissa korostuvan opittujen kirjoitustapojen rutiininomainen soveltaminen, mikä ilmeni oppilaiden yhteisymmärryksenä kirjoitustehtävän tekemisestä ja ryhmän työskentelyyn liittyvistä odotuksista. Tutkimus lisää tietoa siitä, millaisiksi oppilaiden yhdessä kirjoittamisen prosessit luokkahuonetilanteissa muotoutuvat.
Lauseenjäsenet suomen kielen ja kirjallisuuden perusopetuksen oppikirjoissa
Authors: Marjokorpi Jenni
Published: April 2023

Tutkimus tarkastelee aineistolähtöisen sisällönanalyysin keinoin, miten lauseenjäseniä opetetaan vuosiluokkien 5, 6 ja 8 suomen kielen ja kirjallisuuden oppi- ja tehtäväkirjoissa. Lisäksi kirjojen lauseenjäsentehtäviä luokitellaan teoriajohtoisen sisällönanalyysin keinoin. Tutkimuksessa havaitaan alakoulun lauseenjäsenjaksot tiiviiksi ja käsittelytavaltaan tutustuviksi, käsitteiden prototyyppisiä ominaisuuksia korostaviksi ja tunnistamispainotteisiksi. Käsiteltäviksi nousevat predikaatti, subjekti ja objekti. Adverbiaalia ei käsitellä alakoulun kirjoissa lainkaan ja predikatiivi vain yhdessä maininnanomaisesti. Yläkoulussa opetetaan lausekkeen käsite sekä tutustutaan lauseenjäseniin hieman aiempaa laajemmin. Soveltavia tehtäviä on kuitenkin edelleen selvästi tunnistus- ja tuottamistehtäviä vähemmän. Oppikirjojen mukaan jäsentyvä kielioppiopetus on enimmäkseen deskriptiivistä, ja opetussuunnitelman (POPS 2014) funktionaalinen orientaatio ja kielitiedon sitominen tekstitaitoihin näkyvät niissä paikoitellen. Tutkimuksessa pohditaan opetuksen jatkumoa ja sitä, kannattaisiko sisältöjen ja tehtävätyyppien toisteisuutta vähentää tutustumalla kaikkiin lauseenjäsenkäsitteisiin jo alakoulussa sekä painottamalla yläkoulussa soveltavia ja kielenkäyttötaitoihin sidottuja harjoituksia.
 
Clause constituents in comprehensive school Finnish language and literature textbooks
Abstract
The study applies data-based content analysis to examine how clause constituents are presented in nine Finnish language and literature textbook series for schoolyears 5, 6, and 8.  The analysis of the grammar exercises builds on a theoretical framework by Rättyä and Kulju (2018) in which exercise types are classified according to their level of cognitive processes. The results indicate that year 5 and 6 textbooks mainly present the most prototypical features of the clause constituents, focusing on familiarizing the students with the subject, the predicate, and the object (in one book also the predicative), and identifying them in simple clause types. Year 8 textbooks reintroduce the previous concepts, and also teach the adverbial and the concept of phrase. While grammatical description becomes more comprehensive, the exercises still focus on identification and production. Some application and analysis exercises are included. The textbooks teach grammar mainly descriptively, and the functional and contextual orientations of the National Core Curriculum (2014) are present to some extent. The study discusses the continuum of grammar teaching during basic education as well as the possibility of introducing all clause constituents already in years 5 and 6. During years 7 through 9, grammar teaching could focus on cognitively more complex exercises in a functional way that could also benefit the students’ text interpretation and production skills.

Mental Wellbeing and Recreational Sports – Two Together for a Healthy Win - Implications for Higher Education Institutions
Authors: Pandey Aparna , Chopra Anjali , Karve Shailaja
Published: April 2023

The current research highlights how recreational sports enhance student wellbeing and promote physical and mental health through positive social bonding. The Indian social fabric is culturally and traditionally more interconnected as Indians thrive on social networks and engage in several festivals, celebrations, and get-togethers across the year. Therefore, the pandemic and ensuing lockdown created a vacuum. The study explored how students at higher education institutes (HEIs) engaged in Recreational Sports during the lockdown and its role in increasing social bonds, experiencing a feeling of association, positive emotions, relaxing the mind, and promoting overall wellbeing. Further, the present study identifies factors that influence the intention to continue engaging in recreation sports on an ongoing basis (a behaviour that was picked up during the pandemic to cope with lockdown and isolation). The current need  is to understand how learning and developing behavioural competencies can be encouraged through active learning in open spaces to overcome social isolation as all types of physical-sports activities favor psychological wellbeing. The present study uses the TPB (Theory of Planned Behavior) framework to identify factors that influence the intention to continue engaging in recreation sports on an ongoing basis. Social contact time, with many shared experiences, has multiple benefits. It not only helps in stress release but also motivates and provides comfort in the company of friends and colleagues. Therein lies the importance and relevance of Outdoor Behavioral Experiential Learning (OBEL) and recreational sports.

The article presents the results of an experimental study on teachers’ personal qualities, as well as their self-development abilities. The aim of the study is to find out the peculiarities of lecturers’ personal qualities and self-development. Among the lecturers the following personal factors have been found above the average: warmth, rule-consciousness, emotional stability, social boldness, abstractedness, openness to change. And the indicators of self-development are average for lecturers, which shows that lecturers are able to realize their own opportunities, to develop themselves for professional growth. And after the analysis of the questionnaire results, we can conclude that for the Armenian lecturers the actions taken for self-recognition are as follows: self-development, retraining, communication with their colleagues, they prefer to be professional. The lecturers of the psychological weakness considered the following qualities: kindness, sincerity, difficult to accept innovations, lack of language knowledge.

Published: April 2023

Today's education faces modern challenges in the context of profound methodological and content changes in the world. Global realities have a fundamental impact on education processes, research and projected outcomes. As a result of the COVID-19 pandemic and thanks to the development of information technologies, the learning process of higher education is currently organized in a hybrid manner, with combination of face-to-face and distance learning modalities. We were somewhat prepared for it, because yet in 2010, the Government of Armenia had adopted a decision to approve the procedure for distance learning of Higher, Postgraduate and Vocational education specialties (Government of the RA – Hayastani Hanrapetutyun karavarutyan voroshumy. 2010).

 In order to understand the current issues of distance education and aiming to help to improve the process in the context of hybrid education, we conducted research and explored the process of organization of distance learning from different perspectives, tested its effectiveness and identified various problems at Khachatur Abovian Armenian State Pedagogical University?

Proline as an osmolyte modulates changes in morphological and physiological attributes of Capsicum annuum l. under water stress
Authors: Ojewumi Anthony W. , Ayoola Samuel A. , Ope Abdulqudus A. , Iyanda Toheeb M.
Published: April 2023

Water stress is an inevitable factor which limits growth, development, and production efficiency of vegetables such as Capsicum annuum (Linnaeus) (pepper). This study was carried out to investigate the use of proline as an osmolyte to ameliorate the effect of water stress on morphological and physiological attributes of Capsicum annuum. C. annuum seedlings were subjected to different levels of proline (20, 30 and 40 %) against droughted and well-watered seedlings as control in a completely randomized design. Results showed that water stress limits morphological and physiological attributes of C. annuum, while proline at different levels enhances it. Highest plant height (26.00±0.71 cm) was obtained in C. annuum sprayed with 40% proline. Well-watered seedlings of C. annuum produced the highest numbers of leaves (35.40±4.12 cm) and leaf length (12.60±0.68 cm). In addition, leaf area (89.40±2.04 cm2), specific leaf area (124.24±1.24 m2kg-1) and leaf area index (1.76±1.13 m2m-2) were significantly higher (p < 0.05) in C. annuum seedlings sprayed with 40 % proline compared with other treatments. Relative growth rate (0.30±0.09 mgg-1day-1), net assimilation rate (0.47±0.30 gm-2day-1) and leaf area ratio (0.58±0.11 m2kg-1) as well as, chlorophyll content (9.76±0.02 µgcm2), were higher in C. annuum seedlings sprayed with 40% proline. In conclusion, 20 and 30 % proline sustained morphological and physiological attributes of C. annuum under water stress, but 40% proline produced better ameliorative effects.
Preservice Teachers Learn: How Coal Keeps the Lights on
Authors: Schnittka Christine G.
Published: April 2023

At the end of 2022, there were 2439 coal-fired power plants operating around the world, and over 7000 active coal mines (Global Energy Monitor, 2022). Coal burning was the largest source of greenhouse gases that impact climate change, and coal mining caused extensive environmental damage (US Energy and Information Administration, 2022). Decisions about the use of coal in energy production are made by world leaders, but everyday citizens vote for and appoint those leaders. Do everyday citizens understand the most basic science about coal? Do the teachers who are supposed to educate them in their youth? Energy literacy is so important; it leads to informed decisions about energy use at home, wise consumer choices, and to national and international energy policies (DeWaters & Powers, 2011). In this study, 56 pre-service elementary teachers were asked if they understood how coal was used to produce electricity. They were then taught using a constructivist teaching methodology including manipulatives, diagrams, videos, and group discussions (Schnittka, 2017). After the lesson, they were asked again, “How does coal keep the lights on?” Pre-test scores were very low, but gains were strong from pre to post-test. In a delayed post-test, the participants who retained the concepts the best over time had discussed it with a friend or relative. For long-term retention and the ability to potentially apply a concept to everyday life, teachers must realize that learning gains can be ethereal, and that they need to build in tools to aid in long-term retention of concepts. More importantly, teachers need to understand the science and engineering behind the technologies that impact our world so severely, so that they can pass on lessons to youth and advocate for a sustainable future.
Sustaining Religious Education Leadership: Implications for Policy Reform
Authors: Buchanan Michael T
Published: April 2023

Religious education leaders promote the religious identity of the school as well as foster a sense of connectedness through building school community. However, these leaders who play a key role in this area are at times the ones who feel the least connected to the school community and are more likely than other leaders to resign from the position prior to completing their full term. One of the things principals of schools fear the most is the resignation of the religious education leader in their school (Crotty 2005). The high turnover rate of these leaders and the dearth of applicants to fulfil this role have resulted in less experienced personnel being appointed to these positions. Religious education leaders themselves as well as principals are concerned with the lack of suitable successors willing to take on the role. They want successors who are experienced and capable of senior leadership. Over the past decade the religious education leadership policy reforms and initiatives from diocesan based centralised authorities for Catholic education across Australia have attempted to address these concerns. Drawing on the insights from a study into the kinds of support religious education leaders need to do their job effectively, this chapter explores the general limitations of these policies and proposes some recommendations for policy reform that will sustain Religious Education Leadership as a viable career pathway.
Language Policies in STEM Subjects: Triggering Inclusion, Exclusion, or Abjection?
Authors: Andersen Katja N. , Bagger Anette
Published: April 2023

The combination of language policies, the global testing industry, and the role of STEM subjects in school systems have been shown to undermine the inclusion of all pupils, especially with regard to language backgrounds. This lack of inclusion shows signs of developing into a point of systematic exclusion for those students. In this article we will consider the language policies in two national contexts, the Swedish and the Luxembourgish ones, and specifically examine issues of in(ex)clusion in relation to multi-lingualism in STEM teaching. This study analyzes policy documents on (1) inclusion, (2) language use, and (3) STEM teaching at school in the two national contexts, using a methodology that builds on Popkewitz’s (2013; 2014) approach to politics of schooling. Our results show, first, that different policies on language and multilingualism become visible in policy documents for primary school teaching in Sweden and Luxembourg. Secondly, this article discusses what impacts these policies may have on matters of inclusion, exclusion, or abjection in STEM teaching contexts at primary schools.
The Shape of Things to Come: Introduction to Special Issue on Nothing to Come by Correia & Rosenkranz
Authors: Mariani Cristian , Torrengo Giuliano
Published: April 2023

In Nothing To Come: A Defence of the Growing Block Theory of Time, Correia and Rosenkranz present in great depth their own version of the Growing Block Theory. This special issue contains several commentaries on Correia and Rosenkranz’s position made by leading figures in contemporary philosophy of time, together with extremely thorough replies by the authors themselves which clarify crucial aspects of their view.
Taking Tense Seriously Cannot Help the Growing Block
Authors: Dyke Heather
Published: April 2023

Correia and Rosenkranz (C&R) defend their Growing Block theory of time by appealing to the importance of the notion of taking tense seriously. I argue that this phrase is ambiguous, having both a linguistic and a metaphysical interpretation, but neither interpretation will give C&R what they need. On its linguistic interpretation it fails to have the metaphysical significance required to establish the truth of their theory. On its metaphysical interpretation it consists of nothing more than an assertion of their view, or at best, an acknowledgement of its merely possible truth. Finally, I consider C&R’s response to the epistemic objection to their view, according to which, if the Growing Block theory is true, we cannot know that we are located at the objective present moment. The epistemic objection thus undermines the motivation for holding the Growing Block view in the first place. C&R argue that the objection founders because it fails to take tense seriously enough. I argue that taking tense seriously cannot save their view from the epistemic objection.
The Growing Block, the Epistemic Objection and Zombie Parrots
Authors: Markosian Ned
Published: April 2023

In this book symposium contribution, I raise a question about Correia and Rosenkranz’s version of the Growing Block Theory: Is it meant to be a Four-Dimensionalist theory (with a commitment to temporal parts), or a Three-Dimensionalist theory (according to which an object is wholly present whenever it is present)? I argue that a downside of giving the first answer to this question (that the theory is committed to temporal parts) is that in that case their theory will be vulnerable to the Epistemic Objection to the Growing Block Theory. I further argue that an important advantage of giving the second answer to my question (that the theory does not come with a commitment to temporal parts) is that the Three-Dimensionalist version of the Growing Block Theory is not susceptible to the Epistemic Objection. And I also suggest that an apparent disadvantage of saying that their theory is a Three-Dimensionalist theory, namely, that in that case they will have difficulty answering questions about the properties of non-present objects (such as parrots from the distant past), can be dealt with in a way that does not commit them to either zombie parrots or bare particulars.
Tensed Metaphysics and Non-Local Grounding of Truth
Authors: Wawer Jacek
Published: April 2023

It is argued that the assignment of truth values to future contingents is threatened not by a tensed metaphysics but by a temporally “local” notion of truth, i.e., by the assumption that whatever is true at a given time needs to be grounded in what exists at that time. If this assumption is accepted, tensed and tenseless metaphysics are equally vulnerable; if it is rejected, both can accommodate true future contingents. This means that semantic decisions are largely independent of metaphysical considerations. The work of Correia and Rosenkranz (2018) is a clear example of how the tensed metaphysics of the growing block can incorporate true future contingents. Two potential worries are discussed in the context of their work: (a) that their grounding strategy overgeneralizes and admits true counterfactual contingents; and (b) that the growing block theory lacks sufficient resources to distinguish the unique possible future course of events that is relevant for the grounding of future contingents.
The Growing Block, the Open Future and Future Truths
Authors: Torre Stephan
Published: April 2023

In Nothing to Come, Fabrice Correia and Sven Rosenkranz provide a sophisticated, compelling, and thoroughly defended account of the growing block theory. This note critically evaluates two aspects of this account. First, it evaluates Correia and Rosenkranz’s attempt at providing a grounding principle for future truths and argues that this principle fails to make progress in explaining why future truths are true. Second, it evaluates Correia and Rosenkranz’s construal of the open future arguing that the asymmetry in openness with respect to the past and future is not plausibly understood in terms of determinism and indeterminism, and in the final section, it evaluates their claim that a growing block theorist is able to maintain that the future is open in a stronger sense than the block theorist.
Nothing to Come in a Relativistic Setting
Authors: Dorato Mauro , Hoefer Carl
Published: April 2023

In the first part of the paper, we show that C&R’s axioms generate the following dilemma. On the one hand, they could admit that truths about future contingents have no real ground in reality. To reject the requirement of grounding, however, goes against the intuitions of most philosophers concerning truth. On the other hand, C&R could give up bivalence for future contingents at the cost of making their temporal logic more complicated and presumably losing certain theorems. In the second part, we evaluate C&R’s relativistic generalization of the growing block by discussing the various options that can be used to make relativity cohere with the growing block, and we illustrate the reasons why Stein’s “pointy present” looks preferable to bow-tie presentism.

In what follows, we will reply to the critical comments one by one in the order that seemed most natural to us, given the topics covered. Apart from the references section towards the end, our replies are conceived as pieces each of which can be read independently from any of the others (but not, of course, independently from the comments it responds to). We hope to have done justice to the critical points made by our commentators and to have come up with viable answers to the various challenges they raise.

The present research aims to highlight the relationship between locus of control and learning styles. The study was attended by 225 students from several faculties with a humanistic profile in the University of Bucharest, aged between 22 and 23, both male and female. Statistically significant differences in terms of locus of control depending on learning styles, are to be measured in terms of the dependent relationship between the two variables (p < 0.01). On the other hand, we aimed to highlight gender differences depending on learning styles and locus of control (p < 0.01). The results can be used in the adaptation of teaching methods in the university environment.

Authors: Șulea Ionela Cecilia
Published: April 2023

This article shape aspects regarding contravention liability with the help of the regulations mentioned in Law no. 8/1996 and completed with the Government Ordinance no. 2/2001, that forms the frame of contravention sanctions and the method of punishment. In the field on intellectual property contravention liability is not as known as criminal liability, and because of this, this article wants to emphasize its importance within society of today. In the first part, I focus on main and complementary categories of contraventional sanctions, highlighting the low gravity of the deed that form these categories and the purpose of rehabilitation, even the benefits for community, that some of these conventional sanctions have. In the second part, I point out how sanctions are applied, which persons can enforce this law and how it is possible to reach and confer the effect of social rehabilitation. Finally, I underline the need for contraventional sanctions to be rethought and anchored in today’s reality.

Our study focused at measuring stress, anxiety, and depression among the population of university students in Serbia. The sample included 493 students from The Faculty of Mechanical Engineering and the Higher Medical School, Kraljevo, University of Kragujevac, Central Serbia. The electronic survey was completed in approximately 10 minutes. Data collection was conducted during September and October, 2022. The research instruments included: General Questionnaire (used to collect demographic and personal data before and during the COVID-19 pandemic) and Depression Anxiety Stress Scales (DASS-21). All statistical calculations were performed using the standard commercial, standard software package SPSS, version 18.0. 12.8% of students reported severe and very severe symptoms of depression. In 21.7% of cases, severe and very severe symptoms of anxiety were reported. 20.3% of students reported sever and very severe symptoms of stress. Even though there are several studies on the mental health of Serbian college and university students during the COVID-19 pandemic, our article is unique in that it observes their mental health two years after the onset of the pandemic. This allows us to compare the findings with those obtained for the onset of the pandemic.

The objective was to evaluate the effectiveness and safety of video-assisted thoracoscopic surgery for closed chest trauma and to determine the most favorable terms for performing surgical intervention in case of complicated closed chest injury.

METHODS AND MATERIALS. The study included 95 patients who underwent video-assisted thoracoscopy (VATS) for closed chest trauma. Group I – operated within the first 5 days from the moment of injury; group II – operated within 5–10 days after injury; group III – operated later than 10 days after injury.

RESULTS. Performing thoracoscopic intervention within the first 5 days after the injury significantly reduces the incidence of complications such as pneumonia, pleurisy, empyema. VTS allows safely and effectively performing various surgical procedures in case of complicated closed chest trauma, and diagnosing diaphragm injuries.

CONCLUSION. Indications for video-assisted thoracoscopy should be set as early as possible.

Modern approaches to early diagnosis of CRC
Authors: Kiseleva E. V. , Nefedev F. S. , Zaharenko A. A. , Zaraiski M. I.
Published: April 2023

Screening allows detecting not only tumors in the early stages, but also precancerous diseases. Over the past decades, due to the introduction and implementation of screening programs in many Western countries, there has been a gradual decrease in morbidity and mortality. Several screening tests have been developed to detect and prevent colorectal cancer (CRC). These tests differ in technology, cost and object of study. At present, the stool occult blood test and fibrocolonoscopy are mainly used to detect CRC. However, the search for new non-invasive and reliable markers with high sensitivity and specificity and suitable for the early diagnosis of CRC remains an urgent task. Due to the ability of microRNAs to be present outside the formations in various biological fluids of the body and to be determined using the polymerase chain reaction (PCR), the detection of microRNAs has shown significant promise in the diagnosis and prognosis of CRC.
