The consequences of removing fluorinated compounds from rigid contact lenses
Authors: Eddleston Mark D. , Raduly Levente , Tapper Tristan T. , Hughes Reece J. , Browne Gareth M. , Conway Martin J.
Published: May 2023

Fluorine free analogues of three commercially available rigid contact lens materials were prepared by replacing the fluorinated component, hexafluoroisopropyl methacrylate (HFPM), with the widely used, non-fluorinated monomers methyl methacrylate (MMA) and 3-methacryloxypropyltris-(trimethylsiloxy)silane (TRIS). The properties of the commercial materials and analogues were measured and compared. The oxygen permeabilities of the MMA analogues were found to be significantly lower than those of the commercial materials, decreasing by 87 % on average, while the TRIS analogues lacked sufficient hardness, dimensional stability and lipid deposit resistance to be viable for use in rigid contact lenses. Analogues prepared using a 1:1 mixture of MMA and TRIS had the best overall combination of properties, but were still on average 47 % less permeable to oxygen and also significantly less resistant to lipid deposition. The analogues prepared in this study did not adequately replicate the performance of marketed, fluorine containing rigid contact lens materials. These observations give an indication of the challenges that would face contact lens material manufacturers in preparing rigid lens polymers without the use of fluorinated species. A reduction in effectiveness would be almost inevitable, and would be expected to have a negative impact on the safety and eye health of rigid contact lens patients.

Authors: Khanna Nitin , Tamrakar Raunak Kumar , Tiwari Samit , Upadhyay Kanchan
Published: May 2023

Inorganic metal oxide ZnO in the form of nano particles can change the way diseases are diagnosed and treated. ZnO Nps are selective in targeting cancer cells and due to its nano size can enter into cells and destroy it. Drugs, fluorescent agents (for imaging), targeting agents (to target diseased cells only) etc. be loaded on ZnO Nps to deliver drugs selectively in a controlled manner to specific site. ZnO Nps is non toxic as declared by medical community and hence can replace the inaccuracy and harmful side effects of conventional medicine in bulk form. In this review we have discussed about the preparation and characterization of ZnO Nps. Later part concentrated on applications in various fields including biomedical field.
Wertschätzung und WahrheitEine Studie zur gewaltvollen Kommunikation in der Wissenschaft
Authors: Kron Thomas , Härpfer Claudius
Published: May 2023

Wir begründen in unserem Beitrag die These, dass die Art des Kommunizierens wichtigen Einfluss auf das Prozessieren der Funktionssysteme nehmen kann. Wir orientieren uns hierbei an der Unterscheidung wertschätzender//gewaltvoller Kommunikation. Der Argumentationsgang erfolgt in folgenden Schritten: Wir beginnen mit einer Diskussion der Unterscheidung von Handlung und Kommunikation. Im Ergebnis räumen wir den psychischen Systemen einen höheren Stellenwert im Kommunikationsprozess ein als dies bei Luhmanns Kommunikationsmodell der Fall ist. Eine Folge hiervon ist eine erhöhte Relevanz der Sprache und ihrer Vagheit. Zur Erhöhung der Erfolgswahrscheinlichkeit wird Empathie als Kommunikationsmedium vorgeschlagen. Mit diesen Modifikationen demonstrieren wir exemplifizierend an einem Fallbeispiel die Konsequenzen gewaltvoller Kommunikation in der Wissenschaft.
Flow structure comparison of film cooling versus hybrid cooling: a CFD study
Authors: Panda Rajesh Kumar , Pujari Arun Kumar , Gudla Babji
Published: May 2023

Film and jet impingement cooling are widely used techniques in gas turbine vane and blade cooling. The present work investigates and compares the flow structure of a film-cooled flat plate with a hybrid cooling scheme. The hybrid cooling scheme combines both impingement hole and film holes and is named combined impingement-film (IFC) cooling. Experimental validation and computational analyses are carried out on a flat plate with film holes. Different flow parameters, such as velocity pattern, Turbulent kinetic energy, and streamline flow structure, are compared for the two cases in different regions of the flat plate. It is observed that the hybrid scheme shows advantages over film cooling. The jet-to-jet interaction, jet crossflow interaction, and vortex formation are the main factors affecting film cooling performance. There is a 52 % drop in turbulent kinetic energy for the hybrid cooling compared to the film cooling at the film hole exit. More mixing in the coolant and mainstream interaction is observed for the FC case than in the IFC.
Der Mitverschuldenseinwand des Abschlussprüfers – Eine historische, rechtsvergleichende und ökonomische Analyse
Authors: Thomale Chris
Published: May 2023

Die Haftungsverantwortung des Abschlussprüfers für fehlerhafte Finanzberichterstattung bildet einen Grundpfeiler des gesellschaftsrechtlichen Informationsmodells. Dadurch wird sie zugleich zum Seismografen tektonischer Spannungen im Wirtschaftssystem insgesamt, wie insbesondere die weltweiten Bilanzskandale der letzten Jahre belegen. Der vorliegende Beitrag widmet sich dem Mitverschuldenseinwand des Abschlussprüfers, also der Frage, ob und mit welcher Rechtsfolge er gegenüber der eigenen Verschuldenshaftung Sorgfaltswidrigkeiten der Prüfklientin einwenden kann. Eine historisch-rechtsvergleichende Rekonstruktion der dogmatischen Figuren ‚Abschlussprüferhaftung‘ und ‚Mitverschuldenseinwand‘ bietet dabei die Folie für eine ökonomische Analyse. Danach erweist sich eine Schadensteilung zwischen Abschlussprüfer und Prüfklientin als vorzugswürdig, die sich proportional zum pflichtwidrig unterlassenen Vorsorgeaufwand verhält. Gleichzeitig bietet diese sonderprivatrechtliche Studie die Grundlage für eine fundamentale Neuorientierung des Mitverschuldenseinwands überhaupt: Dessen klassisch-naturrechtliche Ausrichtung an der Idee proportionalen Verschuldens ex post erlaubt keine kohärenten Maßstäbe der Schadensteilung. Deshalb sollten der Mitverschuldenseinwand und die in seinem Sinne vollzogene Schadensteilung konsequent an den durch sie ex ante erzielten Handlungsanreizen orientiert werden.
Green’s function analysis of the neutron Lloyd interferometer
Authors: Käding Christian , Pitschmann Mario , Abele Hartmut
Published: May 2023

The neutron optical Lloyd interferometer can serve as a potent experiment for probing fundamental physics beyond the standard models of particles and cosmology. In this article, we provide a full Green’s function analysis of a Lloyd interferometer in the limit that the reflecting mirror extends to the screen. We consider two distinct situations: first, we will review the theoretical case of no external fields being present. Subsequently, we will analyze the case in which a gravitational field is acting on the neutrons. The latter case provides the theory necessary for using a Lloyd interferometer as a probe of gravitational fields.

Niños por la causa
Authors: Terry Jennifer Robin
Published: May 2023

This article argues that children were central to the United Farm Workers’ (UFW) social justice appeal in the late 1960s and early 1970s. As marginalized laborers and a vulnerable group in need of protection, child farmworkers were emblematic of the movement’s aspirations. As agents of protest and activism, both farmworker and non-farmworker children were key to its advancement. Additionally, the article highlights the many ways that the UFW shaped children’s politics, fostered their identity, and contributed to student-led civil rights efforts in rural California. Drawing on a wide variety of sources, including oral histories and children’s correspondence with Cesar Chavez, this article details children’s unprecedented level of labor rights activism in the UFW movement's first decade.
The California Dream
Authors: Warren Louis S.
Published: May 2023

In recent years, press and political leaders have lamented the demise of the California Dream, a vaguely defined, popular ideal of California life that is said to have originated in the gold rush and to have energized California’s ascent. This essay argues that the emergence of a national ideal of California life can tell us much about changes in American culture, especially since the actual history of the California Dream departs so widely from popular perception. The concept of a “California Dream” did not emerge in the gold rush, but only after The Mamas & The Papas’ smash hit “California Dreamin’” in 1965. It served as both a reinscription of the American Dream and a revision of it to incorporate new social values of the Cold War era, including, among others, the importance of leisure, environmental protection, and healthy living. Warnings of the dream’s decline have attended it from birth, and yet it remains surprisingly popular across an increasingly diverse California population. The dream signaled the exceptional growth that distinguished California in the twentieth century and has represented a quasi-national aspiration that both hearkens to older American ideals and implicitly critiques them by offering an ostensible alternative.
Alleviation of Seed Dormancy in Kala Zeera (Bunium Persicum) Through Chilling and Phytohormones

Published: May 2023

Kala zeera (Bunium persicum) is a high-value medicinal spice plant. The seeds and extracts are used for culinary, perfumery, flavouring food and medicinal purposes. The commercial cultivation of kala zeera is hampered due to poor seed germination and deep physiological dormancy.
To break the dormancy of kala zeera, three phytohormones, gibberellic acid (100 μmol L-1), 6-benzylaminopurine (10 μmol L-1) and thidiazuron (6.3 μmol L-1) were tested individually and in combination, under two temperature levels: continuous chilling
at 4°C and one week chilling at 4°C followed by incubation at room temperature. The combined application of the three phytohormones under continuous chilling (4°C) improved the germination from 11.25 to 93.25% and reduced the mean germination time 60 to 50 days. The lowest mean
germination time (34.78 days) and high mean daily germination (1.57 seeds day-1) with a high coefficient of germination velocity (2.88), were found under combined application of phytohormones as compared to their individual application. The findings have implications in successful
propagation and systematic cultivation of this high-value medicinal spice plant.
Neuropeptide Y regulates osteocyte phenotype and function through AHNAK-Smad signalling
Authors: Wu Xiangnan , Wang Yiqiao , Wang Hang , Ma Meirui , Hao Zhichao , Ma Yuanyuan
Published: May 2023

Neuropeptide Y (NPY) is a widespread hormone in the central and peripheral nervous systems that maintains body homeostasis. Central actions of hypothalamic NPY have been identified in bone metabolism. Osteocytes are the main source of NPY in bone tissue, indicating that osteocytic NPY could be a local alternative pathway for hypothalamic mediated regulation of bone and bone cells. Here, we show that osteocytic NPY induces cell viability and proliferation. Osteocyte-derived factors are also closely associated with changes in cellular NPY mRNA levels. Furthermore, osteoblast mineralization was significantly induced by conditioned medium collected from NPY-overexpressing osteocytes (P < 0.05). Importantly, the NPY–AHNAK interaction was identified for the first time by co-immunoprecipitation, and significant inactivation of p-Smad1/5/9 was found in osteocytes with NPY or AHNAK insufficiency (P < 0.05). The activation of p-Smad1/5/9 reversed NPY insufficiency-caused decreases in the expression of osteocytic proliferating cell nuclear antigen and osteoblast markers including osteocalcin and Runx2 (P < 0.05); these findings showed an additional molecular mechanism by which NPY acts on cells through AHNAK-mediated Smad1/5/9 signalling. Collectively, our findings provide novel insights into the function of NPY in regulating osteocyte phenotype and function and provide new insights for further investigation into osteocytic NPY-mediated therapy.

Authors: Herrmann Lisa E. , Elliott Laura E. , Sucharew Heidi , Jerardi Karen , Zackoff Matthew W. , Klein Melissa , Real Francis J.
Published: May 2023

OBJECTIVES

Conflict management skills are essential for interprofessional team functioning, however existing trainings are time and resource intensive. We hypothesized that a curriculum incorporating virtual reality (VR) simulations would enhance providers’ interprofessional conflict communication skills and increase self-efficacy.

METHODS

We conducted a randomized controlled pilot study of the Conflict Instruction through Virtual Immersive Cases (CIVIC) curriculum among inpatient clinicians at a pediatric satellite campus. Participants viewed a 30-minute didactic presentation on conflict management and subsequently completed CIVIC (intervention group) or an alternative VR curriculum on vaccine counseling (control group), both of which allowed for verbal interactions with screen-based avatars. Three months following VR training, all clinicians participated in a unique VR simulation focused on conflict management that was recorded and scored using a rubric of observable conflict management behaviors and a Global Entrustment Scale (GES). Differences between groups were evaluated using generalized linear models. Self-efficacy was also assessed immediately pre, post, and 3 months postcurriculum. Differences within and between groups were assessed with paired independent and 2-sample t-tests, respectively.

RESULTS

Forty of 51 participants (78%) completed this study. The intervention group (n = 17) demonstrated better performance on the GES (P = .003) and specific evidence-based conflict management behaviors, including summarizing team member’s concerns (P = .02) and checking for acceptance of the plan (P = .02), as well as statistical improvements in 5 self-efficacy measures compared with controls.

CONCLUSIONS

Participants exposed to CIVIC demonstrated enhanced conflict communication skills and reported increased self-efficacy compared with controls. VR may be an effective method of conflict communication training.
De vagos a reclutas y desertores. Las deserciones en las milicias coloniales de las provincias del Caribe neogranadino, siglo XVIII
Authors: Daza-Villar Vladimir
Published: May 2023

En este artículo se analizan los esfuerzos por impulsar una reforma militar en el Caribe neogranadino, vistos como medidas de las autoridades coloniales por contener las deserciones de los militares durante el siglo XVIII. Asimismo, se exponen los tratamientos represivos que se instituyeron para controlarlas y comprender la naturaleza de este fenómeno. Para ello, se apoyó en fuentes documentales del Fondo Milicias y Marina de la Sección Colonia del Archivo General de la Nación de Colombia. Este fondo documental, que cubre casi todos los siglos coloniales en el Caribe, contiene noticias sobre prófugos y quejas de las autoridades contra los desertores. La investigación pretende contribuir al estudio de la reforma militar en el Caribe neogranadino en el siglo XVIII en relación con los desertores. Para llegar así a la conclusión de que las estrategias de fuga y de ocultamiento muestran que la decisión de desertar era consciente y mantenida en el tiempo, y, en cierta manera, se trataban de una fuerte oposición al orden social colonial.

Developing and implementing a virtual writing workshop for doctoral students in a Global Leadership PhD program
Authors: Bottomley Kevin , Bourgeois Jeff
Published: May 2023

Writing support is one facet of doctoral education with implications on student retention, persistence, and completion. Previous research suggests focus has been given to undergraduate writing, while little attention has been paid to support graduate writing overall and even less at the doctoral level (Rose & McClafferty, 2001). After observing student struggles with doctoral-level academic writing, members of the faculty determined a need to better support writing development from coursework through the final dissertation in an online Global Leadership PhD program. In this article, we describe the development and implementation of a multi-day, interactive, and synchronous online writing workshop collaboratively offered by faculty and staff to address challenges experienced by pre-dissertation students, as well as those in the dissertation stage of the program. Students had demonstrated a wide variety of challenges, including trouble writing using conventional standards, difficulty organizing their thoughts, understanding and applying appropriate APA formatting, and minor proofreading errors in their writing. These challenges are often exacerbated by differences in priorities from instructors, creating confusion for the student on how to best address these challenges and become more proficient in their writing. Following a description of the practice, we include a discussion on student evaluations of the workshop and make recommendations for the application of similar support initiatives.

The second part of the discussions concerning the Ministerial Sessions of the Baltic Sea States deals with the meetings of ministers which were held between 1999 and 2005. The course of the sessions and the decisions made in Palanga (1999), Bergen (2000), Hamburg (2001), Svetlogorsk (2002), Pori (2003), and Szczecin (2005) were discussed. Attention was paid to political, economic, and cultural issues, as well as to the subject of safety brought up during the debate. The role that the Russian Federation tried to play during these sessions was stressed. The Russian side made attempts to exploit the sessions for the protection of the rights of Russian-speaking population in Lithuania, Latvia and Estonia, and to use the sessions as the convenient international stage for accusing those states of violating human rights. The measures taken by Russia were not successful. As it seems, that failure was mainly caused by the fact that the Russians themselves ran short of determination in their attempts at reaching the aforementioned goals.

Published: May 2023

The article presents the results of the European Social Survey on the political involvement of youth aged 16–29 in Poland, Russia and Ukraine. It can be concluded from the observations that the level of political commitment is low among the researched youths. The phase of life and the social status are the decisive factors affecting a young person’s involvement in politics. Working young people with university education are more likely to participate in political life. Additionally, more commitment to political life is demonstrated in people with higher social status. There are also differences between the youth in the analysed countries. In Russia, young people are more interested in politics and show political party preferences. In Ukraine, the youth more frequently participates in the elections. In Poland, young people are present in various civil campaigns.

Published: May 2023

Feliks Koneczny, professor of history, was one of the most interesting Polish thinkers of the first half of the twentieth century. He was born in 1862 in Krakow. He studied history at the Jagiellonian University. He is primarily known as a philosopher of history and the creator of the theory of civilizations. For Koneczny, history is a confrontation between civilizations. He described seven great civilizations: Arabic, Byzantine, Brahminical, Chinese, Latin, Turanian, and Jewish. Their mutual relations are the axis of history. The Byzantine and the Turanian civilizations were particularly expansive, with the West being the main field of their expansion. According to Feliks Koneczny, the East (the Orient) was the birthplace of civilizations that threaten the Latin civilization.
Chorągiew jazdy hospodara multańskiego (wołoskiego) Konstantego Serbana w wojsku koronnym w latach 1673–1676
Authors:   Uniwersytet Kardynała Stefana Wyszyńskiego w Warszawie, Hundert Zbigniew
Published: May 2023

In 1673 Constantin Şerban formed a banner (military unit, company) of light-cavalry in the Polish-Lithuanian Commonwealth for the purpose of waging war against Turkey. The banner followed the Wallachian model of service. The unit’s founder was the Hospodar (ruler) of Wallachia from the period 1654-1658. Since 1661 he has been living in political exile in the Polish-Lithuanian Commonwealth. The banner he had formed was a part of the Polish (Crown) army establishment until 1676, when it was disbanded. The banner’s actual commander was Florian Dobrzelewski, a nobleman from Sieradz. The Hospodar’s cavalry banner fought in the battle of Chocim in November 10–11, 1673, after which it was transformed into a unit of heavy cavalry on the orders of the Grand Crown Hetman, Jan Sobieski. This transformation entailed an obligation to raise the standard of equipment and to increase the soldiers’ quarterly pay from 31 to 41 Zlotys. At the turn of the years 1673 and 1674 the unit fought alongside the corps of Mikolaj Hieronim Sieniawski in Moldova. Along with its rittmeister Constantin, the unit also took part in the autumn-winter military campaign of 1674–1675. In 1676 the unit was obligatorily equipped with lances, like other banners of heavy cavalry. Afterwards, it became a part of the Michal Zbrozek’s group. Next, the unit found itself in the composition of the crew of Stanislawow, where it took part in the successful defense of this fortress against the main Turkish forces in September. The banner’s size regulated by the letter of recruitment should have amounted to 100 horses. In fact, however, it was far from that number, having no more than 30 people shortly before its disbandment. The unit was composed of the residents of the Polish-Lithuanian Commonwealth. Some of them can be identified as members of the Podolian nobility

Construction of miRNA-mRNA Regulatory Network to Identify Potential Biomarkers in Infantile Hemangioma by Integrated Bioinformatics Analysis
Authors: Zhao Boming , Li Bin , Zhang Jun , Qi Yongjian , Chen Biao , Chen Liaobin
Published: May 2023

Infantile hemangioma (IH) is the most common vascular tumor among infants and children. However, the understanding of pathogenesis about IH has not been fully elucidated, and the potential diagnostic maker remains further explored. In this study, we aimed to find miRNAs as potential biomarkers of IH through bioinformatic analysis. The microarray datasets GSE69136, GSE100682 were downloaded from the GEO database. The co-expressed differential miRNAs were identified by analyzing these two datasets. The downstream common target genes were predicted by the ENCORI, Mirgene, miRWalk, and Targetscan databases. GO annotation and KEGG pathway enrichment analysis for target genes were performed. The STRING database and Cytoscape software were used to construct the protein-protein interaction network and screen hub genes. Then potential diagnostic markers for IH were further screened and identified by using Receiver operating characteristic curve analysis. A total of thirteen co-expressed up-regulated miRNAs were screened out in the above two datasets, and 778 down-regulated target genes were then predicted. GO annotation and KEGG pathway enrichment analysis indicated that the common target genes strongly correlated with IH. Through the DEM-hub gene network construction, six miRNAs associated with the hub genes were identified. Finally, has-miR-522-3p, has-miR-512-3p, has-miR-520a-5p with high diagnostic values were screened out by receiver operating characteristic analysis. In the study, the potential miRNA-mRNA regulatory network was firstly constructed in IH. And, the three miRNAs might be used as potential biomarkers for IH, which also provided novel strategies for the therapeutic intervention of IH.
MODELING THE EFFECT OF PHYSICAL AND CHEMICAL HETEROGENEITY OF GRAIN SURFACE ON NANOPARTICLE TRANSPORT IN A SINGLE PORE IN SOIL
Authors: Joseph Molsy , Pallam Harsha Vardhan , Seetha N.
Published: May 2023

The physical and chemical heterogeneity of soil grains significantly affects nanoparticle transport. However, no quantitative relationships exist for particle deposition rates accounting for grain-surface heterogeneity. This study quantifies the effect of various physicochemical parameters on the nanoparticle deposition rate coefficients in a single heterogeneous pore in soil. A mathematical model is developed to simulate the transport of nanoparticles through an idealized pore of cylindrical shape with rings of the same height on the wall representing roughness. Chemical heterogeneity is considered by assigning positive and negative charges to the top of the ring elements and the remaining area of the pore wall, respectively. Particle transport is simulated by solving the advection-diffusion equation with first-order sorption at the pore wall. Nanoparticle breakthrough curves obtained from simulations are fitted with a 1D advection-dispersion-sorption equation. The pore-averaged deposition rate coefficients obtained thus are satisfactorily described using a power-law relationship vis-a-vis pore-scale parameters. The Damkohler number for nanoparticle attachment to the pore wall is significantly affected by parameters representing pore and particle radii, flow velocity, surface potentials of nanoparticles, and regions of the pore wall having positive and negative charges, and Hamaker constant. However, the Damkohler number for nanoparticle detachment from the pore wall is predominantly influenced by parameters representing particle size, roughness height, surface potentials of nanoparticles, and regions of the pore wall having positive and negative charges, Hamaker constant, and ionic strength. Chemical heterogeneity plays a dominant role in nanoparticle retention than wall roughness. The above relations can be incorporated into a pore-network model to quantify the effect of grain-surface heterogeneity on nanoparticle deposition at the continuum scale.
IMPROVEMENT OF ENERGY COLLECTION EFFICIENCY IN MOBILE SENSOR NETWORKS
Authors: Ka'bi Amin Al
Published: May 2023

A proposed technique for increasing the lifespan of mobile wireless sensor networks that are energy constrained is provided in this paper. This technique is based on the idea that radio frequency (RF) signals simultaneously carry information and energy. Thus, the lifespan of a wireless network can be greatly increased by improving the efficiency of energy harvesting from RF signals. This technique's
simultaneous wireless information and power transfer allows relay nodes to gather energy for use in wireless data transfer. At the receiver side, the transmitted RF energy can be recycled to lengthen the life of the mobile wireless network. Conversely, to maximize the system's overall effectiveness, a balance between energy harvesting and wireless data transfer is necessary. In the suggested method, the received power is divided into two continuous sets of power streams using arbitrary power splitting
ratios. A resource allocation (ResAll) method is used to identify the resource allocation values by taking into account the various power splitting capacities of receivers. The ResAll algorithm system balances the data rate, energy efficiency, power splitting ratio, and transmitted power to achieve energy efficiency. The best resource allocation strategies are then obtained using particle swarm optimization (PSO), which maximizes the system energy efficiency. In the process, a cost function is created and
PSO maximizes the energy efficiency by optimizing the cost function's solution with regard to the restrictions applied during iterations.

Published: May 2023

The objective of this study was to identify the adherence of industrial companies to the criteria of the integrity program established in the anti-corruption law and the implementation of internal controls. Therefore, descriptive research was carried out, based on the application of a questionnaire, reaching a sample of 74 industries, 30% of which have been in operation for more than 41 years and 68% have family and/or mixed management. The results showed that the companies included in the sample have greater adherence to some criteria of the integrity program established by law, however, there are still opportunities for improvement in their control systems. When observing whether companies have a code of ethics, conduct and integrity, 51% have this document, 64% indicated that training on the subject takes place in the corporate environment and regarding the existence of an ethics committee or compliance and a whistleblower channel, the percentage of adherence can be considered relatively low, being 22% and 24%. When addressing the adoption of procedures and internal controls to avoid the occurrence of conflicts of interest and fraud, 50% of the companies have these procedures and 15% did not know how to respond. It was observed that Law 12.846/2013 is still little known, there is an awareness of its importance to reduce the risk of corruption, conflict of interest and increase the degree of transparency of actions, but at the same time, many entities do not yet have policies and procedures in place.
Revisiting how scientific research drives technological change: The Fifth Industrial Revolution
Authors: Callaghan Chris
Published: May 2023

Moll, Marwala, and Ntlatlapa highlight salient criticisms of terminologies and definitional uncertainties associated with the term ‘Fourth Industrial Revolution’ (4IR). Scientific research on technological change seems to suggest a need for theoretical synthesis to address a failure of 4IR notions to consider the central role of a revolution in the scientific/knowledge creation process itself – that is seemingly a causal driver of current technological and societal changes. The term ‘Fifth Industrial Revolution’ might helpfully be used to differentiate 4IR debates from those deriving from revolutionary changes in science itself that may underlie our current trajectory of technological change.

Folk medicine has been considered one of the novel remedies for treating cancers. Women's cancers are increasing worldwide, and disease recurrence has been a major threat all over the world. Our current study focused on the formation of silver nanoparticles (AgNPs) by organic methods and their chemo-preventive capacity against the breast (MCF-7) and ovarian cancer (PA-1) cell lines from humans by employing MTT, Flow cytometry, and migration assays. Plant extracts in organic nanoparticle production have become more common in recent years due to their benefits, including affordability, effectiveness, simplicity and briefness. Melia azedarach leaf and fruit methanolic extracts were used to successfully create silver nanoparticles simultaneously to evaluate the potency and efficacy of the extracts. Characterization studies were performed using synthesized M. azedarach silver nanoparticles (MA-AgNPs). A typical SPR peak was discovered ranging from 400 nm (leaf) and 427 nm (fruit) using absorption spectroscopy, with an average particle size of 92.5 nm (leaf) and 124.1 (fruit) nm. The zeta potential for Melia leaves and fruits was found to be -20.9 and -31.2 mV for the extracts. The relevant functional groups for the capping agent found in the extracts and silver nanoparticles formed as a result of the reduction of silver nitrate were identified using Fourier transform infrared spectroscopy (FTIR). Antimicrobial activity against Escherichia coli, Bacillus aureus, Staphylococcus aureus, and Klebsiella pneumonia would be useful in new antimicrobial medications being developed. MCF-7 and PA-1 cell lines were found to be more susceptible to the cytotoxic action of the biosynthesized nanoparticles. The silver nanoparticles that were synthesized exhibited extremely positive anti-cancer activity.
Etnik Terörde Ahlaki Ayrılma Sürecine Yönelik Politik Psikolojik Yaklaşım
Authors: TUGAY Burcu , DURAN Hasan
Published: May 2023

Etnik terörizm, diğer terörizm çeşitlerinden daha az çalışılan araştırma konusudur. Konuyla ilgili çalışmalar ise genellikle milliyetçilik kavramı altında yapılmıştır. Etnik terörizmi bireyleri anlamlı sosyal dokudan koparan unsurlar üzerinden ahlaki boyutta değerlendirmek, konuya yönelik gelişen yaklaşımdır. Etnik terörün gerçekleşmesinde, etnik kimliklerini tanımlayan dava için fail olanların, suçlarını uygun ahlaki zemine yerleştirme çabasının temelinde “ahlaki ayrılma” süreci yatmaktadır. Ahlaki ayrılmanın alt kavramlarından olan “insan dışılaştırma”, ülkemizde uluslararası ilişkiler alanında çok kısıtlı çalışılmış olan mağdur/kurban bilimini siyasi analize katma noktasında teşvik edicidir. Çalışma, etnik terörün ahlaki sınırlarla etkileşimini ve ahlaki sınırlara meydan okuyuşunu “Sosyal Kimlik Teorisi” kapsamında ele alan literatür araştırmasıdır. Çalışmaya göre, etnik terörizmde ahlaki ayrılma meselesi; duygulardan arındırılmış şekilde değil, kararlı duygu yönetimi ve bilinçli duygusal körlük süreci ile açıklanabilir.

Isolation of sex specific PND 1/2 rat corticalprimary astrocytes v1
Authors: Paranjape Neha
Published: May 2023

Many xenobiotic metabolizing enzymes, such as P450s, SULTs, UGTs, and sulfatases, are expressed in the brain, including astrocytes, the most abundant cell type in the brain. To obtain a purified culture of primary astrocytes, a method was developed and confirmed through flow cytometry. Primary glial cells are isolated separately from male and female postnatal day 1/2 (PND1/2) rat pups to isolate developing astrocytes. Sex is first determined by the anogenital distance and then confirmed through PCR followed by gel electrophoresis. Once isolated, the medium is changed every 3-4 days with additional incubation at room temperature for 10 min on a plate shaker before aspirating media to release microglia. When flasks reach confluency, cells are passaged and reseeded with 2 x 105 cells per flask. Once the cells reached passage 3, or appear to be confluent with only astrocytes, flow cytometry is performed utilizing Anti-Iba1 and GFAP primary antibodies.
Positively Fearful: Activating the Individual’s HERO Within to Explain Volitional Security Technology Adoption
Authors: Mattson Thomas ,   University of Richmond, Aurigemma Sal ,   University of Tulsa, Ren Jie ,   Fordham University
Published: May 2023

Regardless of what security professionals do to motivate personal users to adopt security
technologies volitionally, the end result seems to be the same—low adoption rates. To increase these
rates, we propose activating their positive psychological capital (PsyCap), which consists of hope,
self-efficacy, resilience, and optimism (i.e., their “HERO within”). We propose that greater PsyCap
toward a security technology is associated with greater adoption rates (and intentions thereof)
because positivity increases motivation. We further posit that PsyCap both moderates and is
moderated by other constructs. We suggest that personal users’ conditioned fear from the security
threat moderates the effect of PsyCap on adoption intentions because some fear is necessary to
activate their positive PsyCap to form their behavioral intentions to adopt security technologies. We
further hypothesize that PsyCap moderates the effect of adoption intentions on actual adoption rates
because activating an individual’s HERO within encourages individuals to exert the effort necessary
to translate their intentions into actual adoption. Finally, we theorize that enhancing fear appeal
messages with appeals to an individual’s HERO has a greater effect on volitional adoption rates
relative to messages without these PsyCap-related appeals. To support our hypotheses, we conducted
two experiments using the volitional adoption of a password manager application and a two-factor
authentication (2FA) service. We found differential support for our hypotheses across the two
security technologies, which suggests technology characteristics might mitigate the impact of
PsyCap on volitional adoption decisions.
The Effectiveness of Highlighting Different Communication Orientations in Promoting Mobile Communication Technology at Work vs. at Home: Evidence from a Field Experiment

Published: May 2023

With the development of mobile communication technologies, people can now engage in seamless
communications with family members and coworkers at both home and work. When promoting a
new mobile communication technology (e.g., the 5G network), firms may be tempted to emphasize
how the technology can strengthen communication both within and across the two domains with the
hope of improving purchase rates. Yet research has suggested that people may perceive mobile
communication differently depending on whether those they are communicating with others who
belong to the same domain. Thus, the promotion of the technology to potential users should perhaps
consider users’ location domain and their communication targets. Through a field experiment, we
show that when promoting mobile communication technology in the home domain, highlighting
prevention-focused communication promotes greater purchase rates. However, at work, when
coworkers are the target of communication, highlighting promotion-focused communication works
better. These findings can not only help practitioners design more effective promotional messages in
promoting mobile communication technologies but also contribute to the understanding of nuanced
differences in the nature of mobile communication that make it more appealing to users in different
within- and cross-domain communication scenarios.
