Apakah Overprotektif Orang Tua Berkorelasi Dengan Agresivitas? Studi Pada Mahasiswa Rantau Asal Daerah Yang Pernah Berkonflik Sosial
Authors: Wattimena Marice Meigy , Huwae Arthur 
Published: June 2023

Aggressive behavior is a form of action whose purpose is to hurt or injure another person, physically or verbally. There are several factors behind the emergence of aggressive behavior, one of which is overprotective parenting. Overprotective parenting causes children to feel pressured and less free. Moving on from this, this study aims to find out the correlation between overprotective parents and the aggressiveness of wander students from regions who have had social conflicts. The research method used is correlational quantitative. The study participants were 60 students who came from areas that had experienced social conflict (Moluccas, Papua, Central Borneo and Central Sulawesi) using the incidental sampling technique. Data collection used the Parent Overprotectiveness Scale (α = 0.863) and the Aggressiveness Scale (α = 0.898). The research results prove that the research hypothesis is accepted (r = 0.387 and sig. = 0.002). It can be concluded that the increased aggressiveness of wander students from regions who have had social conflicts is due to an increase in parental overprotectiveness. Perilaku agresif merupakan bentuk tindakan yang tujuannya meyakiti atau melukai orang lain, secara fisik maupun verbal. Terdapat beberapa faktor yang melatarbelakangi timbulnya perilaku agresif, salah satunya pola pengasuhan orang tua yang overprotektif. Pengasuhan orang tua yang overprotektif menyebabkan anak merasa tertekan dan kurang bebas. Beranjak dari hal tersebut, maka penelitian ini bertujuan mencari tahu korelasi antara overprotektif orang tua dan agresivitas mahaswa rantau asal daerah yang pernah berkonflik sosial. Metode penelitian yang digunakan yaitu kuantitatif korelasional. Partisipan penelitian sebanyak 60 mahasiswa yang berasal dari daerah yang pernah berkonflik sosial (Maluku, Papua, Kalimantan Tengah, dan Sulawesi Tengah) dengan teknik insidental sampling. Pengumpulan data menggunakan Skala Overprotektif Orang Tua (α = 0,863) dan Skala Agresivitas (α = 0,898). Hasil penelitian membuktikan bahwa hipotesis penelitian diterima (r = 0,387 dan sig. = 0,002). Dapat disimpulkan bahwa meningkatnya agresivitas mahasiswa rantau asal daerah yang pernah berkonflik sosial, karena adanya peningkatan overprotektif orang tua yang diterapkan.

Published: June 2023

Abstract
The fungal community associated with marine crabs is poorly known, except for the fungi causing diseases of marine animals of economic value. In this study we examined the diversity of fungi cultured from carapace and gut of the marine crab Portunus sanguinolentus, and the identification was based on nucleotide BLAST search results of the internal transcribed spacers of rDNA (ITS). A total of 256 fungal isolates representing 23 species were cultured from seven individuals of P. sanguinolentus including two unidentified species. The majority of the species belong to the Ascomycota, while three species of the Basidiomycota were isolated from the gut. Overall, Candida tropicalis (45.70 %, percentage occurrence), Apiotrichum lignicola (8.98 %) and Rhodotorula sp. (8.20 %) were the dominant fungi on the crab. The most dominant fungi on the carapace were C. tropicalis (66.95 %), Emericellopsis maritima (8.47 %), A. lignicola and Purpureocillium lilacinum (both 4.24 %). In the gut, C. tropicalis (27.54 %), A. lignicola (16.67 %), Rhodotorula sp. (15.22 %) and Fusarium solani (14.49 %) were dominant. The fungal diversity in the gut of P. sanguinolentus was higher than on the carapace according to the diversity indices. Although some of the isolated fungi were reported to be pathogenic, none were reported as pathogens of crabs, and no disease symptoms were noticed from the crab samples.
Virtual Corporate Seat: A Case for Reform?
Authors: Mikalonienė Lina 
Published: June 2023

Abstract

685This article argues that the general location of the registered office of a company without a physical business address in a Member State, accompanied by a digital business address, should qualify a corporate seat as “virtual”. Moreover, the concept of the virtual corporate seat should essentially be seen as a modernized version of the model developed under the substantive company law of some Member States when two separate concepts – the general location of the company’s registered office in that Member State and the domestic business address – are used to determine a fully fledged notion of the corporate seat. The article further addresses the key functions that the virtual corporate seat should perform on an EU-wide, cross-border basis that are typically delivered by the traditional (physical) registered office. It also considers the major challenges that lie ahead of the innovative concept of the virtual corporate seat, chief among which is ensuring proper communication with the company while maintaining a virtual corporate seat.686
Sustainability‐Related Disclosures in Financial Services and Dialogue Policies in Listed Companies
Authors: Della Tommasina Luca 
Published: June 2023

Abstract

782The article analyzes the impact of the Regulation (EU) 2019/2088 on the dialogue policies in listed companies. Starting from the new obligations of sustainability‐related disclosure in the financial services sector, the essay envisages governance solutions which are able to grant interim information flows between the board of directors and the institutional investors about sustainability performances, also in light of the recent Directive (EU) 2022/2464. The essay deals more specifically with the following topics: a) the division of power between directors and supervisory board, and then the directors who are entitled to intervene in the hypothesized ESG-dialogues; b) the modality of the dialogue, if one-way or two-way, and the impact that such ESG-dialogues have on the company’s governance, especially on the relationship between the directors and the supervisory board; c) the possibility of selecting shareholders who are entitled to attend the meeting; d) the relation between the board of directors and the general meeting of shareholders; e) the possibility of involving investors who are not shareholders, particularly a bidder, in ESG-dialogues with institutional investors.783
Harmonising Shareholder Protection Laws for Related Party Transactions
Authors: Florstedt Tim 
Published: June 2023

Abstract

701
Related party transactions have gained significant importance in Europe as a result of the reformed Shareholders’ Rights Directive (SRD). Previously, only a few Member States had created regulatory regimes governing such transactions, yet as of the reform of 2019, detailed procedural and disclosure requirements are compulsory in the European Union today. The Directive’s specifications in Article 9 c grant national legislators substantial discretion to implement new safeguards into national law. This article compares the implementations chosen by Member States and assesses the degree of harmonisation that countries have achieved. It advocates for a more balanced approach and increased coordination with accounting laws. Furthermore, it argues that the new legal regime should be regarded as a significant part of European Corporate Group Law.

New results of uncertain integrals and applications
Authors: Shao Zehui , Kosari Saeed , Yadollahzadeh Milad , Beikaee Seyed Abdollah 
Published: June 2023

Abstract
Based on the uncertainty theory, Liu [B. Liu,
Some research problems in uncertainty theory,
J. Uncertain Syst. 3 2009, 1, 3–10]
introduced an uncertain integral for applying uncertain differential equation,
finance, control, filtering and dynamical systems. Since uncertain integrals are the important content of
uncertainty theory, this paper explores an approach of the relationship
between uncertain integrals by the well-known Chebyshev-type inequality.
Also, we propose the concept of an uncertain fractional integral which is generalized version of an uncertain integral. The definition of a strong comonotonic uncertain
process and some new properties of the uncertain integral were presented in [C. You and N. Xiang,
Some properties of uncertain integral,
Iran. J. Fuzzy Syst. 15 2018, 2, 133–142]. Based on the strong
comonotonic uncertain process, as an application, we provide Chebyshev’s
inequality for a fractional uncertain integral and an uncertain integral.
Schwann cells in neuromuscular in vitro models
Authors: Hörner Sarah Janice , Couturier Nathalie , Hafner Mathias , Rudolf Rüdiger 
Published: June 2023

Abstract
Neuromuscular cell culture models are used to investigate synapse formation and function, as well as mechanisms of de-and regeneration in neuromuscular diseases. Recent developments including 3D culture technique and hiPSC technology have propelled their ability to complement insights from in vivo models. However, most cultures have not considered Schwann cells, the glial part of NMJs. In the following, a brief overview of different types of neuromuscular cocultures is provided alongside examples for studies that included Schwann cells. From these, findings concerning the effects of Schwann cells on those cultures are summarized and future lines of research are proposed.

§ 44 WpHG als Strafe im Sinne der Verfassung – Grenzen privatrechtlicher Normdurchsetzung
Authors: Kochendörfer Luca 
Published: June 2023

Abstract

316
Verstöße gegen die kapitalmarktrechtliche Beteiligungspublizität (§§ 33–47 WpHG) führen gemäß § 44 WpHG zu einem vorübergehenden Verlust sämtlicher Aktionärsrechte. Unter knappem Verweis auf den pönalen Charakter dieser Rechtsfolge begründet die herrschende Meinung von Verfassungs wegen einen – ungeschriebenen – Verschuldensvorbehalt. Weitere Implikationen eines solchen Strafcharakters, namentlich die Anwendung des Gesetzlichkeitsprinzips (Art. 103 Abs. 2 GG) und der Unschuldsvermutung, werden hingegen abgelehnt oder gar nicht thematisiert. Die reich317haltige, in sich zum Teil dissonante Verfassungsrechtsprechung wird dabei nur eklektisch ausgewertet. Der status quo ist sowohl in Begründungstiefe als auch Ergebnis defizitär. Angesichts der erheblichen Auswirkungen für die gesamte Beteiligungspublizität bedarf es einer eingehenderen Analyse der verfassungsrechtlichen Vorgaben, namentlich der Frage, ob und wenn ja wann Rechtsfolgen auf dem Feld des Privatrechts Strafcharakter im Sinne des Grundgesetzes aufweisen. Auf die Sanktion des Rechtsverlusts in § 44 WpHG gewendet kann danach der schon bisher überwiegend geforderte Verschuldensvorbehalt argumentativ untermauert werden. Die Außerachtlassung des Gesetzlichkeitsprinzips und der Unschuldsvermutung sind jedoch vor dem Hintergrund des einheitlichen, auch von der (jüngeren) Rechtsprechung favorisierten Strafbegriffs nicht zu halten. Den angestellten Überlegungen kommt über die kapitalmarktrechtliche Frage hinaus Bedeutung zu, bildet die Sanktion des Rechtsverlusts in § 44 WpHG doch ein Musterbeispiel für den vieldiskutierten Einsatz privatrechtlicher Normen zur Durchsetzung öffentlicher Interessen („private enforcement“). Die Diskussion präzisiert insofern die bisher zu wenig behandelten verfassungsrechtlichen Grenzen des Funktionalisierungsdiskurses.
Specific features of electromagnetic waves in degenerate two stream electron-ion plasma: self-induced magnetic field
Authors: Rozina Ch. , Pervaiz Maryam , Iqbal Zafar , Nadeem Nourina 
Published: June 2023

Abstract
Generation and amplification of magnetic fields is a subject of interest to both laboratory and astrophysical plasmas. The counter-streaming instability or Weibel instability is a mechanism responsible for self-generating magnetic fields in plasmas. In this paper, we investigate that the non-stationary ponderomotive force of a large amplitude electromagnetic wave (EMWs) propagating through dense two stream quantum electron ion plasma, may lead to the generation of d.c. magnetic fields. It is shown that degeneracy parameters, specifically the exchange correlation potential and Fermi pressure can reduce/control the self-induced magnetic field. Next the linear propagation of EMWs through plasma under consideration has also been considered in the presence of exchange correlation potential along with other quantum effects. Linear dispersion relation, the instability conditions and growth rate have been derived. It is found that the degeneracy parameters stabilize the propagation of instability and lead to reduction of the exponentially growing magnetic field. Threshold scale length of EMWs is also obtained for the stable propagation. The present result may be account helpful to understand the seed magnetic fields in dense plasmas.
Selective oxidation of benzene to phenol in the liquid phase over copper-substituted LaFeO3 perovskite oxide as catalyst
Authors: Mistri Rajib 
Published: June 2023

Abstract
Selective oxidation of benzene to phenol is done in the liquid phase over copper-substituted LaFeO3 perovskite oxides as catalyst using H2O2 as oxidant under mild reaction conditions. Among the different copper-substituted perovskite catalysts synthesized by a novel solution combustion method, the LaFe0.90Cu0.10O3 catalyst showed highest activity (∼56 % with 100 % selectivity of phenol) and also gives better activity than the corresponding catalyst made via incipient wetness impregnation of 10 at % Cu over combustion-synthesized LaFeO3. XRD analysis revealed formation of the perovskite phase as the predominant one. The greater activity of the combustion-made catalyst has been attributed to the occurrence of a peculiar poorly-defined structure having substitutional copper ion sites on top of the LaFeO3 particle as observed in HRTEM analysis. Much less occurrence of this phase in the impregnated catalyst, where copper is primarily present as dispersed CuO crystallites, explains its comparatively lower activity in the oxidation reaction. The effect of catalyst recycling shows negligible change of activity for the combustion-made catalyst whereas the analogous impregnated catalyst shows considerable decrease in activity in recycling. This explained to be due to the essentially intact poorly-defined structure in the former and leaching of the finely dispersed CuO crystallites from the latter catalyst during cycling.
LIGAÇÕES ENTRE GENÉTICA, GEOMETRIAS E PROBABILIDADE
Authors: Filho Nilo Pinto Da Silva , Nunez Emílio , Martins Caubi Blanck 
Published: June 2023

RESUMO
A Genética é uma ciência que se dedica ao estudo da hereditariedade, baseada muitas vezes nas teorias da Probabilidade. Nesse ramo da Biologia, os fenômenos envolvem eventos aleatórios, onde ocorre o encontro de gametas masculinos e femininos com os genes da fecundação. A Geometria, desde a Grécia antiga, dedica-se ao estudo de figuras planas ou espaciais e suas propriedades. Descartes o criador da Geometria Analítica no plano, conseguiu unir a Álgebra com a Geometria, através da criação do Plano Cartesiano. O presente artigo objetiva demonstrar que ciências como Genética, Probabilidades, Geometria Plana e Geometria Analítica podem se aliar na busca pelo aprofundamento do conhecimento humano e evidenciar que nesses tempos onde a tecnologia avança tão rapidamente, torna-se inevitável admitir, de forma inequívoca, a indivisibilidade do conhecimento humano.
MÉTODO DE LIE PARA EQUAÇÕES DIFERENCIAIS PARCIAIS DE SEGUNDA ORDEM
Authors: Filho Nilo Pinto Da Silva , Nunez Emílio , Martins Caubi Blanck 
Published: June 2023

RESUMO
Este trabalho apresenta uma solução heurística para equações diferenciais parciais de segunda ordem. Com esta finalidade desenvolvemos um algoritmo para se determinar as simetrias infinitesimais de Lie, onde seus infinitésimos xi(x,y) e h(x,y) são tratados, supostamente, como sendo funções polinomiais de segundo grau. A determinação das funções infinitesimais se faz necessário para a determinação da equação característica da equação diferencial inicial. O interesse do processo então se foca na determinação dos coeficientes polinomiais. Uma vez determinadas as simetrias, substituímos na equação característica e integramos para obter a solução por quadratura. Para esse processo utilizamos a condição de invariância, da função resposta, para a transformação de Lie. Fixados os infinitésimos, construímos geradores de simetria e mostramos que estes formam grupos fechados. O trabalho também apresenta o que chamamos de método de solução pelo invariante onde, de uma determinada simetria, obtemos uma transformação para as variáveis de Lie o que nos permite encontrar novas soluções para a equação diferencial parcial. Para exemplificar o algoritmo usamos a equação do calor, uma 2pde bem conhecida na literatura. Um programa, na plataforma MAPLE, também foi desenvolvido no auxílio dos cálculos.

Richard Lovelace's Selected Animal Fables and the Transformation of the Emblem Tradition
Authors: Ismail Araz 
Published: June 2023

It is difficult, if not impossible to give a comprehensive, cogent definition of the ‘emblem’ to accommodate its diversity as a genre, a definition that covers all the works produced under the name emblem during the sixteenth and seventeenth centuries. It is, therefore, neither necessary nor possible here to discuss definitions for such a large and eclectic field like the emblem tradition. Soon after its emergence, the emblem became an accepted form and exercised a vast influence over literature, art, and decoration of the period. Many writers were fascinated by it, including English poet Richard Lovelace (1616-1657), who used strategies of emblem books in his representation of creatures by integrating pictures and texts in a genre. This paper is an attempt to read Lovelace's poems The Grasshopper, A Fly Caught in a Cobweb, The Ant, The Snayl ‘The Snail’, and The Falcon in the light of the emblem tradition, showing how Lovelace uses the tradition. Focusing on his animal fables, the paper illustrates the different ways in which Lovelace employs or transforms the strategies of emblem books. Various references will be made to the poems to explain how the poet capitalises on the emblem heritage, while at the same time adapting it by rewriting the original story behind the emblem to channel his staunch political views in favour of the Royalists. The paper contends that, without referring to the emblem legacy accessible to Lovelace, certain aspects of his poetry would remain ambiguous.
