The metal complexes of pyridine derivative ligand 2- ((E)-2-(1-(4-methylpyridin-2-yl)ethylidene)hydrazinyl) -4-methyl-6-phenylpyridine-3-carbonitrile (MPHPC) derived from 2-hydrazinyl-4-methyl-6-phenylpyridine- 3-carbonitrile and 1-(4-methylpyridin-2-yl)ethanone with metals [Co, Ni and Cu] have been synthesized and characterized with different spectral investigations viz.UV-Vis, FT-IR, 1H-NMR and ESR. The ligand and metal complexes were screened for in vitro cytotoxicity studies against two carcinoma cell lines A549 (Lung carcinoma cells) and HepG2 (Hepatocellular carcinoma cell). The results were found to possess cytotoxic effect. The ligand and metal complexes were screened for in vitro antibacterial activities against for pathogenic bacterial strains such as gram –ve bacteria like Pseudomonas desmolyticum, Escherichia coli and Klebsiella aerogenes as well as gram +ve bacteria like Staphylococcus aureus. The antibacterial studies were determined by agar well diffusion method using DMSO as negative control and Ciprofloxacin as positive control. Cobalt and nickel complexes show a moderate sensitivity whereas copper complex has significant activity at higher doses.

Published: March 2022

A mild and an efficient method catalyzed by copper iodide in TMEDA as solvent was used for the synthesis of bis(indolyl) methanes through a cascade process between indole and substituted aromatic aldehyde to produce the corresponding bis (indolyl) alkanes in moderate to good yields under reflux conditions. All structures of the desired products were evaluated using spectroscopic techniques 1H NMR, 13C NMR spectroscopy and LCMS. The structure of the compounds was determined by elemental analysis. The antibacterial activity of newly synthesized compounds was investigated against gram positive bacteria (Escherichia coli and Pseudomonas) and gram negative bacteria (Bacillus subtilis and Staphylococcus aureus). Anti fungal activity of some newly synthesized compounds was examined against three pathogens such as Aspergillus Niger, Aspergillus favus and Candida albicans.
Quantum effects in photosensitization: The case of singlet oxygen generation by thiothymines
Authors: Manae Meghna , Hazra Anirban
Published: March 2022

Photosensitization is the indirect electronic excitation of a molecule with the aid of a photosensitizer and is a bimolecular nonradiative energy transfer. In this study, we have attempted to elucidate its mechanism, and we do this by calculating rate constants of photosensitization of oxygen by thiothymines (2-thiothymine, 4-thiothymine and 2,4 dithiothymine). The rate constants have been calculated using two approaches: (a) a classical limit of Fermi's Golden Rule (FGR), and (b) a time-dependent variant of FGR, where the treatment is purely quantum mechanical. The former approach has previously been developed for bimolecular systems and has been applied to the photosensitization reactions studied here. The latter approach, however, has so far only been used for unimolecular reactions, and in this work, we describe how it can be adapted for bimolecular reactions. Experimentally, all three thiothymines are known to have significant singlet oxygen yields, which are indicative of similar rates. Rate constants calculated using the time-dependent variant of FGR are comparable across all three thiothymines and with experiment. While the classical approximation gives reasonable rate constants for 2-thiothymine, it severely underestimates them for 4-thiothymine and 2,4 dithiothymine, by several orders of magnitude. This work indicates the importance of quantum effects in driving photosensitization.

Over a span of two years ago, since the emergence of the first case of the novel coronavirus (SARS-CoV-2) in China, the pandemic has crossed borders causing serious health emergencies, immense economic crisis and impacting the daily life worldwide. Despite the discovery of numerous forms of precautionary vaccines along with other recently approved orally available drugs, yet effective antiviral therapeutics are necessarily needed to hunt this virus and its variants. Historically, naturally occurring chemicals have always been considered the primary source of beneficial medications. Considering the SARS-CoV-2 main protease (Mpro) as the duplicate key element of the viral cycle and its main target, in this paper, an extensive virtual screening for a focused chemical library of 15 batzelladine marine alkaloids, was virtually examined against SARS-CoV-2 main protease (Mpro) using an integrated set of modern computational tools including molecular docking (MDock), molecule dynamic (MD) simulations and structure-activity relationships (SARs) as well. The molecular docking predictions had disclosed four promising compounds including batzelladines H-I (8-9) and batzelladines F-G (6-7), respectively according to their prominent ligand-protein energy scores and relevant binding affinities with the (Mpro) pocket residues. The best two chemical hits, batzelladines H-I (8-9) were further investigated thermodynamically though studying their MD simulations at 100 ns, where they showed excellent stability within the accommodated (Mpro) pocket. Moreover, SARs studies imply the crucial roles of the fused tricyclic guanidinic moieties, its degree of unsaturation, position of the N-OH functionality and the length of the side chain as a spacer linking between two active sites, which disclosed fundamental structural and pharmacophoric features for efficient protein-ligand interaction. Such interesting findings are greatly highlighting further in vitro/vivo examinations regarding those marine natural products (MNPs) and their synthetic equivalents as promising antivirals.
Confinement of Luminescent Guests in Metal-Organic Frameworks: Understanding Pathways from Synthesis and Multimodal Characterization to Potential Applications of LG@MOF Systems
Authors: Gutiérrez Mario , Zhang Yang , Tan Jin-Chong
Published: March 2022

This review gives an authoritative, critical, and accessible overview of an emergent class of fluorescent materials termed “LG@MOF” — engineered from the nanoscale confinement of luminescent guests (LG) in a metal-organic framework (MOF) host, realizing a myriad of unconventional materials with fascinating photophysical and photochemical properties. We begin by summarizing the synthetic methodologies and design guidelines for representative LG@MOF systems, where the major types of fluorescent guest encompass organic dyes, metal ions, metal complexes, metal nanoclusters, quantum dots, and hybrid perovskites. Subsequently, we discuss the methods for characterizing the resultant guest-host structures, guest loading, photophysical properties, and review local-scale techniques recently employed to elucidate guest positions. A special emphasis is paid to the pros & cons of the various methods in the context of LG@MOF. In the following section, we provide a brief tutorial on the basic guest-host phenomena, focusing on the excited state events and nanoscale confinement effects underpinning the exceptional behavior of LG@MOF systems. The review finally culminates in the most striking applications of LG@MOF materials, particularly the “turn-on” type fluorochromic chemo- and mechano-sensors, non-invasive thermometry and optical pH sensors, electroluminescence and innovative security devices. This review offers a comprehensive coverage of general interest to the multidisciplinary materials community to stimulate frontier research in the vibrant sector of light-emitting MOF composite systems.

Published: March 2022

As a result of the rapid global challenges related to the nature of the crime over the past two decades and the criminal justice systems’ need for forensic graduates and practitioners who possess the necessary knowledge, skills, and capabilities and demonstrate high levels of professionalism, it is now more essential than ever to truly invest developing the education and training systems in the field of criminal justice and forensic sciences. This development should include the academic programs, the curricula, the pedagogical approaches, the assessment methods, and the practice-based facilities available, the research environment, and the partnerships in place between the educational institutions and the industry stakeholders (e.g., forensic laboratories, police departments, forensic science centers, research institutes, etc.).
This study provides a comprehensive worldwide review of forensic educational approaches and accreditation programs/frameworks. The aim of such a review is to prompt Arab forensic academic institutions to engage into a deeper educational and curricular conversation about how to continuously develop, review, and advance their academic and training programs to meet the needs of the forensic science community and their local judicial system.
This review strongly argues for creating an Arab forensic accrediting body that can
work closely with the various forensic academic and training institutions across the Arab
world on creating a set of standards and educational frameworks that are benchmarked
against international standards while maintaining the local contexts in each Arab country.
The aim of these standards and educational frameworks is to ensure consistency among the Arab countries in terms of program and course learning objectives, curricula, teaching methods, and assessment practices in a manner that addresses the required practical forensic skills, capabilities, and competencies; emphasizes workplace best practices; and prompts continuous training, research and development, and sustainable growth for both the forensic practitioners and forensic centers and laboratories.

Authors: Maltzahn Kathleen , Cox John , MacLean Sarah , Whiteside Mary , Lee Helen
Published: March 2022

Bingo is a distinct, enduring but understudied form of gambling. It provides comfort and pleasure to many of its players while also causing harm to some. While traditionally seen as low harm, it is being reshaped by technological and regulatory change. Despite this, there is no recent overview of the literature on bingo. This narrative review seeks to fill this gap by exploring the development of literature on bingo since the 1980s, first providing a chronological overview of writing on bingo and then a brief account of major themes in the literature. The literature reviewed was primarily identified through searches of academic databases using search terms such as betting, bingo, electronic and gambling. We find that bingo research makes a number of important contributions: it allows better understanding of groups of overlooked gamblers, corrects biases in gambling literature, highlights the importance of social and structural factors in understanding gambling and employs methodological approaches that are congruent with the people and practices being studied.  Additionally, it provides new perspectives on gambling in terms of skill, affect, harm and control and offers a distinct viewpoint to analyse gambling and other phenomena.

Legal Protection for Rape Victims in Indonesia: Seeking an Ideal Concept
Authors: Dewi Aida , Dimyati Khudzaifah , Subakti Natangsa , Absori Absori , Nurani Siti Syahida
Published: March 2022

This paper analyzes and provides advice on legal protection for rape victims in Indonesia in transcendental, restorative law, and responsive law perspectives. These perspectives are compared and combined in an effort to seek an ideal concept. The implication of this paper is to provide advice for an ideal concept of legal protection for victims of rape in an Indonesian context. This paper uses a normative juridical approach with a legal interpretation method. This paper concludes that law enforcement against perpetrators of rape in the Indonesian context can employ transcendental, restorative law, and responsive law approaches. However, in an effort to find an ideal concept, the transcendental perspective of maṣlaḥah mursalah which considers benefits for the public and prevents harm is more suitable for use in Indonesia’s pluralistic society. This is because, in addition to emphasizing moral, ethical, and religious values ​​in law enforcement, the approach will prevent recurrence of cases through handing out severe punishment to perpetrators of rape and providing physical and psychological rehabilitation to victims to make it in line with restorative justice in which victims get the right to recover physically and mentally without reducing the punishment for rape perpetrators.
Grandfather Clause in the Trade Sector as a Security in Investment after Job Creation Act
Authors: Fitriyani Anisa Hesti , Dirkareshza Rianda
Published: March 2022

This study discusses the application of the Grandfather Clause, especially in the trade sector, as a form of certainty in investment law after the issuance of the Job Creation Act. The main issues discussed in this study are how to apply the Grandfather Clause to ensure legal certainty for investors and business actors in the trade sector pre-Job Creation Act. And whether the Grandfather Clause can be a form of legal certainty for investors and business actors in the trade sector that engaged in the post-Job Creation Act. Of course, the aim is to analyze the application of the Grandfather Clause, especially in the trade sector, as a means of legal certainty for investors or business actors engaged in the trading sector. The research method used is a normative research method with a statute approach. The research results show that implementing the Grandfather Clause after changes of the Negative Investment List (DNI) from year to year can provide legal certainty for investors and business actors. In addition, it is also known that the actual implementation of the Grandfather Clause can be adjusted according to the preferences of investors and business actors. In this case, the Grandfather Clause may not be applied if it is felt that the provisions and licensing requirements in the existing regulations are considered more profitable.
Making sense of performance information on effectiveness, costs, and equality during the COVID-19 pandemic. The importance of reference points for citizens’ performance information use
Authors: Mikkesen Maria Falk
Published: March 2022

This paper uses the COVID-19 pandemic as an extreme case to test whether reference points affect how citizens use performance information on effectiveness, cost, and equality. Drawing on the evaluability hypothesis, the paper argues that citizens are more likely to make decisions based on performance information on equality and disregard performance information on effectiveness and costs when no reference points are available to aid interpretation. The paper uses a pre-registered between-subject conjoint survey experiment on 2,025 Danish citizens to test expectations. Respondents were randomly drawn to rate either one fictive government strategy to combat the Coronavirus—with no opportunity to compare performance information between strategies—or two strategies—with the opportunity to compare performance information between strategies. The strategies varied on effectiveness (mortality rate), costs (overall economic costs) and equality (distribution of the economic costs and access to testing). Results show that when respondents are presented with one strategy, only performance information on equality affects ratings. Strategies with lower fatality and lower economic costs are thus not rated higher than strategies with higher fatality and higher economic costs holding other factors constant. In contrast, when respondents are presented with two strategies, performance information on mortality rate and economic cost plays a significant role for citizens’ ratings. Even during a high-information high salience crisis such as COVID-19, citizens are thus more likely to make decisions based on performance information on equality than effectiveness and cost when no ‘yardstick’ is available. Results imply that performance information on effectiveness and cost risk being drown out by other information easier to interpret if not presented with relevant reference points.
Tangible information and charitable giving: When do nonprofit overhead costs matter?
Authors: Qu Heng , Levine Daniel Jamie
Published: March 2022

Nonprofit organizations in the U.S. have been under the pressure to demonstrate their “worthiness” by minimizing overhead costs. Prior experiment studies find that donors respond negatively to high overhead costs when overhead information is highlighted. In reality, donors receive all sorts of information about nonprofit organizations from various channels. While high overhead has been found to reduce donors’ perceived impact and donations, providing other types of tangible information can increase charitable giving by enhancing donors’ perceived impact. When other types of information are available, to what degree overhead aversion still exists? We use two online survey experiments to examine how information on overhead costs and donation use affect giving decisions in a single-organization and two-organization evaluation setting. We found that only a small proportion of people demonstrated overhead aversion when presented with a single organization. There was stronger evidence of overhead aversion when participants were asked to compare and choose between two organizations. Nonetheless, providing tangible information about what donations can buy mitigated overhead aversion in both settings. This study contributes to the growing experimental research on the relationship between overhead ratios and charitable giving, and provides practical insights for nonprofits hoping to ameliorate overhead aversion and increase donation support.

Improving lexical errors in EFL writing by using software-mediated corrective feedback
Authors: Chacón-Beltrán Rubén , Echitchi Raymond
Published: March 2022

This research aims at revisiting the role of software when it comes to providing learners with corrective feedback on their pieces of writing. The study, based on the analysis of handwritten and software-corrected versions of essays written by 33 undergraduate students enrolled in the undergraduate degree programme in English Studies at a Spanish University contributed to confirming the assumption that technology can indeed be a useful tool in the teaching and learning process. More specifically, this study demonstrated that students could reduce significantly the number of lexical errors in their essays through the autonomous use of error-correction software and that, over time, the students can improve on their ability to avoid such errors. Nevertheless, the study has also confirmed that software can in no way completely replace teachers, as computer programming is quite limited and there are errors that only proficient language users can detect and correct.

Given the pervasiveness of American products framed by an increased access provided by digital globalization, it reveals particularly useful to approach such texts from a critical academic perspective. Stemming from the answers a diverse range of students gave—and considering their limitations—the study delves into how popular culture informs and shapes the students’ disposition toward learning, consequently allowing to outline how a course in American Studies could be developed in order to exploit such texts and effectively stimulate a more diverse understanding of the American context(s).

›The Viable Small Change of Moral Education‹. Pedagogical Pathways to Tolerance in the Writings of the Ethical Movement

In this paper, a historical-systematic approach to pedagogical practices for promoting tolerance is developed based on selected texts of the Ethical Movement in Germany and the United States. The paper answers the question of how pedagogical practice and self-formation were conceptualized in order to educate tolerant individuals and thus reform society. It is shown that tolerance is not an adjunct in all the considerations taken into account, but rather a stated goal as a conscious acceptance of the otherness of others.

The Pedagogically Organized System of Lifelong Learning: In the Mirror of Living Conditions (›Lebenswelt‹) and System

The author examines the question of how professionally organized learning units can be described on an abstract-analytic level. In doing so, he turns away from concepts based on the existence of an educational system. Instead, he initially refers to the distinction between informal, non-formal and formal learning, he combines this scheme with theories of Jürgen Habermas and, eventually, develops a classification system tailored to the pedagogically organized system of lifelong learning.

Untuk mempersiapkan dan mematangkan pemahaman siswa menghadapi new normal, perlu dilakukan edukasi dan eksekusi secara serius terkait penerapan protokol kesehatan, sehingga tidak hanya sekedar narasi berupa perintah penerapannya, namun memberikan pemahaman secara mendalam dan praktik kepada siswa sebagai bentuk kepedulian dan kesadaran diri dalam siswa setelah ia memahami maksud dan tujuan dari penerapan protokol kesehatan itu sendiri. Sasaran dalam kegiatan ini adalah siswa dan guru di SD Negeri 1 Masiri. Metode pelaksanaan kegiatan terdiri dari 3 tahap kegiatan, di antaranya 1) kegiatan sosialisasi yang dilakukan melalui metode ceramah terkait panduan pelaksanaan pembelajaran tatap muka bagi daerah zona hijau dimasa pandemik melalui penerapan protokol kesehatan; 2) kegiatan simulasi, dengan mempraktikkan secara langsung tahapan pelaksanaan protokol kesehatan secara runtut dan tepat; 3) kegiatan evaluasi, pembagian masker gratis, hand sanitizer, dan sabun cuci tangan.
