Les enjeux et le statut des méthodologies de l’imaginaire à l’ère du numérique
Authors: Thomas Joël
Published: May 2022

Un regard croisé entre les méthodologies de l’imaginaire et la théorie générale des systèmes est parfaitement pertinent, du fait des nombreuses analogies entre les deux approches. Il nous permet de mieux cerner les enjeux qui se présentent à nous dans le domaine du numérique. On s’efforcera de montrer, à travers quelques exemples empruntés à des univers totalement séparés (la symbolique des gravures rupestres ; le design automobile…) que, avec une grande constance, le modèle systémique associant ordre et désordre participe d’une symbolique du tissage en réseau : unitas multiplex. Dans ce contexte de complexité, l’avenir appartient peut-être aux ordinateurs quantiques…
L’imaginaire des TIC en questions
Authors: Robert Pascal
Published: May 2022

La notion d’imaginaire des TIC, qui connaît un réel succès, doit-elle être prise, sans autre forme d’inventaire, comme un cadre pertinent de compréhension des TIC ou bien doit-elle faire l’objet d’une mise en discussion ? Cet article pose une série de questions à cette notion afin d’en tester la cohérence et l’efficacité intellectuelle. Il montre que la notion (et ses déclinaisons, mythes et utopie notamment), à défaut d’être véritablement convaincante sur le plan intellectuel, remplit une fonction sociale singulière : elle rassure le sociologue (au sens large) quant à sa capacité à porter un discours, fondé sur l’héritage d’anciennes catégories, sur la prolifération de nos techniques. Cette communication indique également qu’il existe des alternatives, peut être mieux adaptées à leur objet, et notamment la notion d’impensé informatique (et des TIC).
Imaginaire éducatif et technologies numériques
Authors: Rinaudo Jean-Luc
Published: May 2022

Le projet de ce texte est de montrer comment s’articule l’imaginaire autour du numérique et de la fantasmatique de la formation. Le numérique se construit sur un imaginaire social qui va de l’assujettissement à la libération et comment les pratiques éducatives conjuguent un travail psychique de déliaison et de subjectivation. Trois modalités des imaginaires du numérique en éducation sont analysées : l’accès à tous les savoirs du monde et les transformations de l’apprentissage et de l’enseignement qui en découlent ; l’abolition des frontières spatiales et temporelles ; la mise en cause des générations. L’auteur formule une hypothèse autour de l’impossible métier d’éducateur pour rendre compte de la permanence de ces imaginaires.
Imaginaire(s) de la jeunesse à l’heure du numérique
Authors: Cordier Anne
Published: May 2022

Nos recherches en sciences de l’information et de la communication nous conduisent à travailler la notion d’imaginaire(s) d’Internet comme objet socialement partagé et objet d’enseignement-apprentissage, de la recherche d’information et des lieux d’information. Plus précisément, nous focalisons sur les liens entre imaginaires et pratiques d’information. Cette publication propose une analyse des imaginaires que véhiculent les discours sociaux à propos des « Jeunes », et de leurs pratiques numériques, et cherche à mettre en lumière la réception de ces discours par les adolescents eux-mêmes, et les conséquences de tels discours sur la prise en charge des pratiques numériques adolescentes.
Des jeux vidéo comme œuvres et véhicules expérientiels
Authors: Serdane Thierry , Siegel Claire
Published: May 2022

Plus que le simple fun qui revient comme un leitmotiv dans la description des jeux vidéo, certains de ces objets dépassent la sphère mercantile de l’expérience de l’immédiateté et de l’éphémère pour délivrer un plaisir plus complexe qui passe au travers des différentes strates du médium vidéoludique. C’est de ce plaisir et de son potentiel contre-culturel dont il sera question par la proposition du concept de « véhicule expérientiel », comme co-construction d’expérience, mettant en relation l’intention d’un concepteur inscrite dans les valeurs de son époque et le voyage proposé au cœur de l’usage du joueur, pilote de son expérience.
Metal Halide Perovskite and Perovskite−like Materials Through the Lens of Ultra−wideline 35/37Cl NMR Spectroscopy

Published: May 2022

With their exceptional optoelectronic features, metal halide perovskites (MHPs) are pushing the next wave of energy−related materials research. Heretofore, most solid–state nuclear magnetic resonance (NMR) investigations have focused on readily accessible nuclei. In contrast, the halogen environments have been avoided due to their challenging quadrupolar nature. Here, we report a rapid 35/37Cl NMR strategy for MHPs, halide double perovskites (HDPs) and perovskite−inspired (PI) materials embracing ultra−wideline acquisition approaches at moderate and ultrahigh magnetic fields. The observed quadrupolar NMR parameters (CQ and η), supported by GIPAW−DFT computations, provide an analytical fingerprint revealing distinct features for chemically unique Cl environments sensitive to ion mixing, dimensionality, cell volume and Cl coordinating polyhedra. Moreover, we report resolution between two nearly identical and two distinct Cl environments of 3D and 2D Cs–based lead halide perovskites, respectively. These results reveal a strategy for a routine and robust spectroscopic approach to analyze local Cl chemical environments in metal halide perovskites that can be extended broadly to other halogen containing semiconductors.
A Quantum Mechanical Description of the Diffusion Properties of C1-C2 Hydrocarbon Molecules in MOF-74-Mg
Authors: Degaga Gemechis , Studinger Amanda , Valenzano-Slough Loredana
Published: May 2022

Among the numerous metal organic framework (MOF) families, of significant importance is the MOF-74-M series (M = metal, -also known as CPO-27-M), characterized by a high density of not fully coordinated open metal site centers; this peculiarity has been demonstrated to translate into a higher hydrocarbons’ separation potential than other known MOFs and zeolites. To provide a more comprehensive description of the behavior of the hydrocarbon molecules within the MOF-74 cavity, diffusion processes and corresponding diffusion barriers of small hydrocarbons in the MOF-74-Mg were modeled. This work provides a description of the molecular transport processes of CH4, C2H2, C2H4 and C2H6 within and along the cavity of MOF-74-Mg; in addition, the influence of pre-adsorbed water molecules is also addressed. Density functional theory (DFT), as implemented within a plane-wave (PW) approach under periodic boundary conditions (PBC), has been used to investigate the diffusion mechanisms using the climbing-image nudge elastic band (CI-NEB) method, coupled with the van der Waals functional (vdW-DF) and ultra-soft pseudopotentials. Two transport mechanisms were identified: M1, referring to the molecular migrations within the MOF cavity; and M2, referring to the molecular migrations along the MOF longitudinal channel. The M1 transport mechanism was further analyzed to address the molecular migration from one metal atom to its adjacent one (M1a), and with respect to the second metal over (M1b). All the transport mechanisms considered show that the diffusion of paraffin molecules in MOF-74-Mg is energetically more favorable than that of olefin molecules. An interesting trend is observed across all the diffusion mechanisms where the stronger the molecule binds to the open metal site, the higher the diffusion barrier it needs to overcome. For all the small hydrocarbons considered in this study, transport mechanism M1a is significantly more energetically favorable than M1b, showing that it is easier for molecules to drift along the longitudinal cavity than to remain trapped cross-sectionally within the cavity itself. This work shows how this computational approach can be successfully applied not only to reveal the molecular transport in other MOF-74 isostructural species, but also in the fundamental understanding of the screening of MOFs and other nano-porous materials for gas separation applications.

Glutathione (GSH) is the most abundant thiol in mammalian cells and plays a crucial role in maintaining the redox state of many biomolecules, in detoxification and in antioxidant defence. The thiols of two GSH molecules can be oxidized to the disulphide GSSG. The cytosolic GSH/GSSG ratio is very high (> 100), and its decrease can lead to apoptosis or necrosis, which are of interest in cancer research. CuII ions are very efficient oxidants of thiols, but with an excess of GSH, the formed CuIn(GS)m clusters are only slowly re-oxidized by O2 at pH 7.4, and even more slowly at lower pH. Here, the oxidation of GSH by CuII was investigated in the presence of the anticancer thiosemicarbazone Dp44mT. The results showed that CuII-Dp44mT oxidizes GSH faster than CuII alone at pH 7.4, and hence accelerates the production of the very reactive hydroxyl radicals. Interestingly, the GSH oxidation and hydroxyl radical production by CuII-Dp44mT were accelerated at the acidic pH found in lysosomes, where CuII-Dp44mT was previously shown to accumulate and induce lysosomal membrane permeabilization. To decipher this unusually faster thiol oxidation a lower pH, Density Functional Theory (DFT) calculations and spectroscopic studies were performed. The results suggest that the acceleration is due to the protonation of CuII-Dp44mT on the hydrazinic nitrogen, which favours the rate-limiting reduction step without subsequent dissociation of the CuI-complex. Furthermore, preliminary biological studies in cell culture using the proton pump inhibitor bafilomycin A1 indicated that the lysosomal pH plays a role in the activity of Dp44mT.
Assessing Enzyme-Catalysed Phosphorylation of Nucleosides to Aid Synthetic Approaches to Novel Antiviral Nucleotides
Authors:   , Dye Crispin
Published: May 2022

Nucleoside analogues acting as chain terminators of viral RNA and DNA polymerases represent an effective therapeutic strategy for the inhibition of viral replication and treatment of viral infections. These compounds must be anabolised into their triphosphate forms before inclusion into the nascent nucleic acid chain by the relevant polymerase thus their action is somewhat reliant on intracellular phosphorylation machinery. The synthetic addition of α-, β-, and γ-phosphate groups to the 5’-carbons of these compounds may provide a means to circumvent this reliance and produce more effective antiviral nucleoside analogues. This can be achieved through the utilisation of enzymes as a synthetic tool, enzymes capable of phosphorylating nucleoside analogues can be expressed in and purified from bacterial cell lines for use in the synthetic process.

The present study has optimised the catalytic reaction of human UCK1 for synthetic purpose and assessed the activity of the enzyme against a range of nucleoside analogues. A range of nucleoside kinase enzymes were recombinantly expressed and purified with the goal of developing an enzymatic reaction process with synthetic utility. A linear regression model capable of calculating the substrate turnover of UCK from 31P NMR spectra of reaction samples was developed, and optimal conditions for a PK-coupled UCK reaction were identified (12.5 mM substrate, 1.5 mg/mL UCK, 3 mg/mL PK) using this model. Under the previously stated reaction conditions UCK1 was found to phosphorylate 71.68% of cytidine and 14.12% of uridine in the sample in a thirty-minute duration, translating to a production of 2.90 mg of CMP and 0.57 mg of UMP from 1 mL reaction volume. Assessment of UCK1 activity against unnatural substrates of the enzyme revealed 13.67% conversion of 5-methyl-U to the corresponding monophosphate. UCK1 was also shown to have phosphorylative activity against aza-C and riboaminopyrrole via LCMS analysis, at a level below the sensitivity of the 31P NMR-based model. The results of this study reinforce the importance of the sugar moiety in nucleoside binding to UCK and indicate a low tolerability of the enzyme for modifications to the substrate at this moiety. These results also suggest the potential of UCK1 to be used as a tool in the synthesis of nucleobase-modified nucleoside analogues.

The reaction process developed in the present study represents a significant step towards the development of an efficient means of synthesising phosphorylated derivatives of nucleoside analogues through enzyme-catalysed reaction. Future efforts on this research should focus on the development of an effective means of isolating product compound from the reaction mixture and increasing the scale of reaction to be synthetically useful.

UD. Sayur Mayur merupakan perusahaan distributor sayur-mayur, buah-buahan dan bahan baku makanan lainnya yang melakukan pemesanan produk kepada pemasok lalu didistribusikan ke setiap retail, dimana tujuan distribusi yang memasok bahan baku makanan dari UD. Sayur Mayur berada di wilayah Malang Raya, Yogyakarta dan Jawa Tengah. Dalam memenuhi permintaan retailer, perusahaan melebihkan jumlah pesanan kepada pemasok sebesar 9% hingga 40% terganting jenis produk untuk mengantisipasi adanya cacat/rusak karena produk bersifat perishable atau tidak tahan lama. Pertimbangan melebihkan pesanan tersebut ternyata berdampak pada timbulnya bullwhip effect atau peningkatan variabilitas permintaan. Maka dari itu, tujuan dari penelitian ini adalah untuk mengetahui nilai bullwhip effect di tingkat distributor, tingkat retailer dan tingkat retailer kategori produk, sehingga nilai bullwhip effect merupakan dasar penentuan rekomendasi perbaikan untuk mengatasi permasalahan bullwhip effect pada perusahaan. Berdasarkan hasil perhitungan, dapat diketahui bahwa terjadi bullwhip effect sebesar 81.3% di tingkat distributor, 80% di tingkat retailer, dan 66.7% di tingkat retailer kategori produk. Produk maupun kategori yang mengalami bullwhip effect dimana nilai BE lebih besar dari parameternya dipengaruhi oleh adanya selisih yang cukup signifikan antara demand dan order, sedangkan produk maupun kategori yang berada di posisi stabil dipengaruhi oleh selisih antara demand dan order yang tidak signifikan sehingga nilai BE tidak melebihi parameternya.
Marriage with Same Tribes in the Customary Law of Minangkabau Batipuh Ateh (A Legal Anthropology Approach)
Authors: Sopyan Yayan , Suryani Helma
Published: May 2022

This paper explores the causes of the prohibition of ethnic marriage in Minang Batipuh Ateh. This legal anthropological research uses a qualitative approach. Information and data are obtained by observation, interviews and literary studies. Informants were selected purposive and developed using the Snowball method. The analysis used an interactive model. The results showed that, the prohibition of tribal marriages in Minang Batipuh Ateh aims to restore the disturbed balance due to violations committed by a person and to maintain the existence of the culture and lineage of the Minang tribe based on matrilineal. Apart from that, the prohibition of inter-ethnic and ethnic marriages in Batipuh Ateh, because: 1) maintaining and preserving customary law; 2) limiting associations; 3) give birth to quality offspring; 4) does not interfere with children's psychology; 5) do not lose their customary rights, and 6) customary payment sanctions. Sanctions for violations of tribal marriages in Batipuh Ateh are: 1) the perpetrator was expelled from Nagari 2) the penalty imposed on Ninik-Mamak by paying a fine; 3) thrown away according to custom, or discarded saro, and 4) excluded from social interactions. Therefore, the permissibility of tribal marriages originating from different Nagari is a solution provided by traditional leaders, as an answer to the changing times, and accommodation to the view of Islamic marriage law, although with strict conditions, to maintain the existence of customary law.
The Epystimology of Islamic Jurisprudence on Covid-19 Vaccine in Indonesia

Published: May 2022

The Covid-19 vaccination program in Indonesia, practically has received a pro and contra in the society. In this context, the Majelis Ulama Indonesia (MUI) came through its fatwa to respond the contra-productive of the community over the succession of the vaccination program. This study analysis the epistemological basis of Islamic law in the construction of the MUI Fatwa Number. 02 of 2021 about Covid-19 Vaccine Products from Sinovac Life Sciences Co. Ltd. China And Pt. Bio Farma (Persero). This qualitative research used philosophical approach, statute approach and conceptual approach. The results show, the epistemological construction of the MUI fatwa No. 02 of 2021 about the Covid-19 vaccine, Sinovac tends to integrate the paradigm of idealism and realism of Islamic law. The tendency of the integrative paradigm can be seen from the epistemological basis of the MUI fatwa formulation on the halalness of the Sinovac Covid-19 vaccine, which is normative-deductive and empirical-inductive, beside that still use preventive fiqh rules (sad al-dhariah) and benefit (maslahatul mursalah) as the basis for formulating a fatwa. This conclusion can be seen in various elements in the epistemological construction of the MUI Fatwa. First, universal ethical moral values ('am) are taken from the texts (al-Qur'an and Hadith). Second, several fiqh rules emphasize the sadd al-zari'ah (preventive action) and maslahah mursalah (public benefit). Third, the opinion of classical scholars. Fourth, the thought of experts regarding the Covid-19 vaccine.

Published: May 2022

Since the beginning of the second decade of the 21 st century, a new blockchain technology (which has not yet been widely used in Russia) has appeared in the world. The paper considers the history of its origin, the stages of implementation, the current state and prospects of development; it gives ex- amples of implementing the technology in the world and in various spheres of the Russian economy including the example of launching a digital platform for knowledge exchange and copyright management for the Ministry of Education and Science of Russia and that of the successful implementation of blockchain technology in Moscow and in a number of regions of the country with electron- ic remote voting during the elections of deputies to the State Duma of the 8 th convocation in September 2021, etc. The article also analyzes the positive dy- namics of the growth in publication activity and citation of Russian researchers in this field of knowledge in 2015–2020. Based on scientometric indicators and using the RSCI system the authors identified promising areas of research for Russian scientists in this subject area among them are legal aspects of the use of smart contracts and blockchain technologies under Russian law; blockchain as a communication basis for the formation of the digital economy: advantages and challenges; approaches to international regulation of cryptocurrencies in certain foreign jurisdictions; cryptocurrency and blockchain technology in the digital economy: the genesis of development; blockchain as a technology for changing existing business models. In conclusion, the paper highlights the main issues that at present slow down the active introduction of blockchain technology in Russia among them an issue of the lack of an appropriate full- fledged legal framework in this area; the lack of a single arbitrator who would be trusted by all users of the technology, etc.
COORDINATE REPRESENTATION OF RABI OSCILLATIONS OF AN ARTIFICIAL ATOM IN AN OPTICAL CAVITY

The possibility of the electron oscillations in a two-well potential is investigated in the article. The Hamiltonian of the system is calculated taking into account the formulas of the James-Cummings model. The unitary dynamics is carried out using a general solution of the Schrodinger equation. The conditions for the parameters of the problem under which the oscillation takes place are shown. These conditions for the exact formulation are discrete. However, it is valuable to find out at what parameters of the problem there occur approximate oscillations, at which an incomplete transition of a particle from one well to another is observed. In the standard manuals on the quantum theory of a single particle, the Hamiltonian was considered from the very beginning without photons, so it was assumed that complete oscillations always take place. This approximate consideration corresponds to reality only with a high potential between the wells. If the potential is low, the wells actually merge into one well, so that the spectrum and eigenvalues of the Hamiltonian become similar to the spectrum and eigenvalues of a one-dimensional potential – a radically different case. Such a discrepancy occurs due to ignoring the interaction of the electron with the electromagnetic field. If such an interaction is taken into account we get the dynamics described by the Jaynes-Cummings Hamiltonian. At a low potential, the energy gap between the ground and excited energy states of the electron grows. Since the probability of photon emission is proportional to this value, the interaction with the field cannot be ignored.

Making an informed decision about the loading of machine parts during operation is of importance for assessing durability both by calculation methods and in laboratory tests. Engineers must create a so-called generalized load block based on taking into account the distribution of their work time during operation. Since the loading of transport vehicles is not stationary, the study of modes is an important issue for making a decision: the list of modes should be neither too long nor too short. Cluster analysis, as one of the machine learning tools, was used in this work to distinguish modes, looking similar at first glance. Since the generalized loading block is created to assess the durabi- lity, those parameters were chosen that are associated with accumulating the fatigue damage. Based on empirical data, a cluster analysis was carried out, which was later checked by the “teacher” – that is, by the a priori information available to researchers.
ein lǫg ok einn siðr: Law, Religion, and their Role in the Cultivation of Cultural Memory in Pre-Christian Icelandic Society
Authors: Nygaard Simon
Published: May 2022

ABSTRACT: The transmission of law in pre-Christian Iceland was an oral process in
an oral society. In oral societies, such transmission processes may be characterized
as a cultivation of cultural memory, which suggests that it was transmitted through
a ritualized performance by a memory specialist. In the Icelandic context, this specialist
was in all likelihood the lǫgsǫgumaðr. However, the connection between the transmission of law by the lǫgsǫgumaðr and ritual
and religion has not yet been established explicitly. This is the subject of the present
article, which first views the intricate relationship between law and religion in
pre-Christian Iceland through the lens of Max Weber’s theory of value spheres and
subsequently treats the transmission of early Icelandic law as a cultivation of cultural
memory.

Propostas Curriculares e a Educação para as Relações Étnicorraciais no Ifes – Ressonâncias outras nos documentos institucionais.
Authors: Pina Ignêz Brigida de Oliveira
Published: May 2022

Este texto se mostra um exercício de reflexão sobre a proposta curricular em Educação para as Relações Étnicorraciais – Erer do Instituto Federal do Espírito Santo - Ifes. Objetivou-se realizar uma análise crítica-reflexiva do Projeto Pedagógico Institucional – PPI, que retrata as concepções ontológicas e epistemológicas da instituição e dos Relatórios de Gestão que trazem os resultados de cada exercício. Uma busca por ecos das propostas assumidas nos resultados apresentados, delineando assim os percursos institucionais na dinâmica de implementação da Erer enquanto proposta curricular. Ao (re) visitar os documentos do Ifes, em busca de marcadores que pudessem indicar as concepções e ações institucionais de implementação da Erer, investiu-se da concepção de currículo enquanto campo de possibilidades pensadas e as práticas curriculares como frutos híbridos das intencionalidades e possibilidades outras – imponderáveis. A compreensão de currículo ora apresentada mostrou-se alternativa de acomodação das complexidades e engendramentos que compreendem as relações étnicorraciais enquanto proposta curricular, ou seja, a Erer e o currículo enquanto territórios de disputa, se aliam constituindo um campo em disputa, um campo unificado que vai ao encontro não somente do reconhecimento da diversidade como potencialidade – transcendendo, portanto, as questões meramente de acesso aos sistemas escolares - mas que também traz para a centralidade das possibilidades pensadas e praticadas os aspectos históricos, estruturais, sociais, culturais, políticos e humanos das relações raciais brasileiras, possibilitando, assim, a construção positiva da identidade de grupos sociais que vivenciam até hoje graves distorções e desigualdades de toda sorte como herança de uma cultura colonialista e escravocrata que constitui o nosso país. Amparando-se na pesquisa documental e compreendendo que os documentos analisados são a essência das possibilidades pensadas, mas que pouco podem espelhar as possibilidades praticadas pelo Ifes, conclui-se que há tentativas, acenos amistosos em direção à Erer, mais especificamente nos dois últimos anos analisados. Todavia, não há como ignorar o silêncio institucional em determinados períodos. A Erer é responsabilidade institucional de reparação de uma população historicamente aligeirada de seus direitos, dentre eles o direito à educação. Políticas de Erer são reparatórias e demandam ações imediatas – sintoniza-ação, sob a pena de perpetuar o racismo, o preconceito, as desigualdades e as atrocidades cometidas e reproduzidas como herança escravocrata aos povos negros e indígenas no Brasil. Logo, compreende-se que ainda sintonizando, pois sintoniza-ação, ressonância, só será possível analisar mediante a concretude dos acontecimentos, das possibilidades outras, aguardando reverberações das tessituras praticadas - ecos que competem a você e a mim - a cada um de nós.

Introduction: Overweight and obesity during pregnancy is associated with increased risk for cesarean delivery. BMI is the most frequently used parameters to define and to assess risk of pregnancy related complications. Maternal abdominal subcutaneous fat thickness (SCFT) can be used as a measure of obesity. The present study was done to find association of maternal SCFT with risk of cesarean section. Methods: 200 women with singleton live pregnancy at 16-18 weeks were included in the study after obtaining written informed consent. Ultrasonography was done to assess foetal wellbeing and rule out congenital malformation. Maternal abdominal subcutaneous thickness was measured. All women were followed during labour till discharge. ROC curve analysis was done to predict the risk of cesarean section. Odd ratio for SCFT mediated risk of cesarean section was calculated. Results: 32.5% women had cesarean delivery. Mean SCFT was also significantly more in women delivered by cesarean than who delivered vaginally (p <0.001). ROC curve analysis for SCFT showed that SCFT above 11.5 mm (AUC=0.735) predicted LSCS with a sensitivity of 86.2% and specificity of 47.4% and Youden index of 0.34. Increased abdominal SCFT was significantly associated with increased risk of LSCS. . Using 11.5 mm cut -off value (by ROC curve) for SCFT, the odd ratio of LSCS was 7.5 (95% CI 3.4056 – 16.5837, p <0.0001). Stitch line infection was seen in 15.38% women. Conclusion: This study observed that measurement of SCFT by ultrasonography at 16-18 weeks pregnancy is a significant predictor of cesarean section.

One prominent aspect of forensic deoxyribonucleic acid testing is the establishment and expansion of centralized national forensic DNA databases and body of evidence have continued to emerge, demonstrating the extensive efficiency and effectiveness of the DNA database in assisting criminal investigation globally. Therefore, the present study aimed to examine public awareness on Forensic DNA Database and the willingness for storage of DNA profiles. The design used in this study is the survey research design and the sample size of this study was a total number of five hundred University of Benin students drawn from our population for empirical investigation. The study adopted descriptive statistics which involves the use of frequency and percentage. The result of this study revealed that majority of the respondent demonstrated an adequate level of awareness and knowledge (71.2%), showed good knowledge on the function of a national forensic DNA database (54.4%), demonstrated increased level of awareness and knowledge on the benefit of a national forensic DNA database (44.8%), and revealed that 422 (84.4%) were willing for the storage of their profiles in the national forensic DNA database.The study also observed that a vast proportion of the respondents indicated that fear of violation of individual’s privacy was the only barrier they considered for the storage of DNA profiles in the National Database and our observations provides a good a basis for reviewing and implementing policies that find a reasonable balance based on the creation of moral and ethical spectrum involving professionals in the area of forensics, law enforcement and the public, in particular, social groups which are less involved in genetics.

Infants’ early understanding of different forms of negation
Authors: Szabó Eszter , Kovács Ágnes Melinda
Published: May 2022

How do infants acquire the meaning of abstract words expressing negation? ‘No’ is among the first uttered words and emerges around the age of one, nevertheless, it is a subject of intense debate when and how exactly infants start interpreting utterances containing negation. According to one hypothesis, early in development, the comprehension and the production of verbal negation is restricted to a narrow range of meanings, for example to non-existence (‘No cookies’), and only much later infants develop a broader understanding and can correctly interpret propositional denial (‘Not x’) that may map onto a fully-fledged negation concept. Alternatively, however, they may rely on an adult-like negation concept from early on, but some forms of negations may pose more mapping difficulties. Here we tested infants’ understanding of two syntactically and semantically different forms of negation, existential negation and propositional denial. We engaged 15- and 18-month-old infants in a search task where they had to find a toy in one out of two locations based on verbal utterances involving existential negation or propositional denial. In Experiments 1-3 we found a parallel development for these two kinds of negation. 18-month-olds successfully comprehended both, while 15-month-olds did not understand either forms of negation. In Experiment 4 we excluded the possibility that 15-month-olds’ poor performance is explained by task-related difficulties. The parallel performance of the two age groups in the tasks involving two types of negation suggests that different forms of negation may share common conceptual underpinnings already in early development.
