Published: August 2024

The Newcastle disease virus (NDV) poses a significant threat to commercial chicken operations and is prevalent in Bangladesh. This rapidly spreading viral illness has severe economic implications for the poultry industry globally. In Bangladesh, the velogenic strain of NDV is particularly widespread. This study utilized primers from the Fusion (F) and Matrix (M) genes along with haemagglutination (HA) testing and reverse transcription-polymerase chain reaction (RT-PCR) to isolate and identify NDV. Post-mortem examinations provided 12 samples (from brain, trachea, and proventriculus) taken from four birds suspected of having NDV from Trishal and Mymensingh Sadar. The samples were injected into 10-day-old embryonated chicken eggs using the chorioallantoic membrane technique. Embryos and allantoic fluid (AF) were collected at 48 and 96 hours post-infection. NDV-infected embryos showed edema and hemorrhage. Significant hemagglutination was observed in the allantoic fluid tested with HA. Through the HA test and lesion observation, four NDV isolates were identified. Pathotypic characterization of the field isolates using the Intracerebral Pathogenicity Index (ICPI) and Mean Death Time (MDT) indicated velogenic strains (ICPI: 1.5–2.0, MDT: <60). RT-PCR confirmed the NDV status of all four isolates using primers for partial amplification of the F gene (839 bp) and the common sequence of the ‘F-M’ genes (970 bp). This study demonstrates that RT-PCR is an effective molecular technique for the rapid and confirmatory identification of velogenic NDV strains, particularly prevalent in Mymensingh at the field level.

AI detection of malicious push notifications in augmented reality in the workplace
Authors: Katz Sarah
Published: August 2024

Distraction caused by the visual processing of multiple objects during augmented reality (AR) immersion could make users more susceptible to malicious push notifications, thus potentially exposing organisations to unwitting insider threats. This case study consulted four experts in the field of AR application development to design a proposed artificial intelligence (AI) equipped feature that could detect possibly malicious artefacts entering the user’s line of sight during partial immersion in an augmented reality application at the workplace. Participants included a business partner at an AR company, a security engineering manager, an AI engineer focused on machine learning (ML) and a data analytics specialist. The case study determined that a security application natively implemented into the device could use heuristic analysis of user screen captured activity to assess potentially malicious push notifications in real time.
Common pitfalls when mitigating cyber risk : Addressing socio-behavioural factors
Authors: Işik Öykü , Viskovich Yanya , Pavitt Si
Published: August 2024

Although humans constitute a pivotal dimension of the cyber security attack surface, prevailing approaches are often ineffective at addressing human risk. From the vantage point of three key socio-behavioural perspectives, a critical analysis of contemporary cyberattacks and cyber security practices offers insights and a range of opportunities to manage the human factor in cyber security. First, the role of metaphors in shaping cyber security discourse, particularly militaristic analogies, is analysed, supported by research advocating for careful metaphor selection to enhance comprehension, foster shared responsibility and reduce counterproductive assumptions. Secondly, the paper explores the significance of psychological safety within organisational cultures. It discusses the concept of a ‘just culture’ and the impact of cultivating an environment that encourages risk reporting. The discussion expands to highlight the interconnectedness of security culture with broader organisational values, emphasising the critical role of leadership in shaping resilient cyber security postures. Finally, an examination of blame-centric practices and associated consequences provides an insight into less visible forms of victim blaming, such as phishing tests and traditional training-centric strategies. It offers a psychological perspective on the distinction between blame and accountability and highlights the need for a shift away from a compliance-based focus towards a positivist approach. In presenting insights from these three key perspectives, this paper offers opportunities to innovatively manage socio-behavioural risk in cyber security, critiquing prevailing approaches that fail to do so. By linking metaphors, psychological safety and blame-centric practices, it contributes to a comprehensive understanding of the human dimension in cyber security and provides a foundation for advancing effective risk management strategies.
Rethinking Performance: The Challenge of Identifying and Dealing with Mediocrity
Authors: Farid Mehar Tahir , Shoukat Iqra
Published: August 2024

This study aims to conceptualize mediocrity, how a mediocre person survives in the organization, and how to eradicate that problem. A Plethora of research focuses on low and high performance; surprisingly, mediocrity in organizations remains largely overlooked. Despite the lack of attention from organizational scholars, mediocrity remained relevant and pinching problems. Partially this neglect is caused by a lack of clear conception of the mediocrity construct. It has been conceptualized contradictorily as poor performance, lack of commitment, lack of opportunity, and inadequacy of leadership traits. The biggest test of an organization is not poor performance —it is mediocrity and how it addresses mediocrity. Mediocrity is a multifaceted concept, having psychological, behavioral, and social facets. A Mediocre is a person who holds a survival instinct but lacks the vision to outperform and the passion for leading. These psychological traits lead to a behavioral dimension where he commands minimum skills, satisficing commitment, and satisfactory performance (not more than required). Eventually, the person earns a reputation that this is an average person who is not a top performer but does a good enough job. In an increasingly competitive business environment, organizational survival depends on identifying and dealing with mediocrity. Unless mediocrity is defined and validated, the antecedents, consequent, and vis-à-vis their solutions offer little to theory and practice for dealing with this slow killer of organizational performance (i.e., Mediocrity). The phenomenology research method is used whereby 10 participants are selected for the interview. A purposive sampling technique is used for this study, and a two-phase coding cycle is used to conduct the analysis.

UM SÍMBOLO CHAMADO MANDALA
Authors: Gomes Rosilene
Published: August 2024

A presente pesquisa enfatiza o significado da palavra mandala que é um círculo ou esfera da essência em sânscrito, uma língua ancestral da Índia, e suas definições externa como uma representação visual do universo e interna como um guia para várias práticas espirituais que ocorrem em diversas tradições asiáticas, incluindo a meditação. Nas culturas religiosas como do budismo e hinduísmo existe uma crença de que ao entrar numa mandala e se direcionar ao seu centro, a pessoa é guiada para um processo cósmico de transformação do sofrimento em alegria e felicidade. Para essas duas religiões esse maravilhoso círculo auxilia na concentração da prática meditativa e são encontradas nos seus templos, simbolizando o universo e a mente humana. Na cultura dos povos indígenas norte-americanos, como os Sioux, esse incrível círculo é chamado de filtro dos sonhos e tem o poder de proteção dos maus sonhos e espíritos malignos. Já no cristianismo as mandalas são símbolos da cura e são vistas nos vitrais das catedrais góticas. Os desenhos de mandalas podem ser encontradas também nas artes, objetos de decoração, na natureza e até nas edificações. Assim o objetivo de estudo tende a analisar as ideias práticas das confecções de mandalas de todos os tipos e práticas espirituais, tais como: de Chakras que envolvem energia vinculadas as cores e símbolos; de animais totêmicos ligadas as figuras de lobo, urso, cavalo e outros; de Yoga que auxiliam na meditação e mantras; de Geometrias sagradas que são compostas por formas geométricas complexas como Sri yantra, cubo de metatron ou flor da vida; de Arte abstrata que varia as criações de acordo com criatividade do artista; de Crianças sendo mais simplificadas e compostas por elementos do mundo infantil; de religiosidades que são confeccionadas com cruz cristã, OM hindu, estrela de Davi e outros. Enfim a pesquisa será de campo e metodologia em estudo de caso, num universo de realidade multidimensional e multicultural. Portanto as mandalas vão além da construção de uma arte, envolve no momento da criação individual ou em grupo uma demonstração de sentimentos e o que está dentro de cada um, a fim de promover o autoconhecimento, emocional e equilíbrio mental e ajuda liberar emoções retraídas, e cada indivíduo envolvido no processo pode expressar pensamentos, emoções e sentimentos de maneira não verbal, ajuda assim a restaurar a harmonia interna, aliviando a ansiedade, depressões, melhorando a saúde mental.

Breaking Through the Glass Wall: How Organizations Can Support Women Freelancers
Authors:   Utah Valley University, Westover Jonathan
Published: August 2024

Abstract: This article explores the "glass walls" women freelancers and entrepreneurs perceive as barriers to their professional advancement and business development, through an examination of existing research on unconscious gender biases and social norms that delineate how subtle stereotypes associate leadership more readily with masculine traits, undermining some women's confidence in their expertise while also revealing studies that show this dynamic hinders women's self-promotion and willingness to position themselves as prospective business owners. Additionally, the piece investigates how closely-knit 'old boy's clubs' and networking traditions privileging stereotypically masculine social activities disadvantage women seeking clients within their industries, while organizational dynamics like homogenous cultures and family-unfriendly policies unintentionally exacerbate these issues, limiting women's access to opportunity. The article concludes by outlining practical, research-backed strategies organizations can implement to break down glass walls through inclusive practices such as auditing for biases, establishing mentorship programs, and showcasing female role models, sending a strong message that all entrepreneurs will find supportive communities where talent alone determines success through a judicious, data-driven approach that progressively advances equity within the freelance sphere.

Authors:   Utah Valley University, Westover Jonathan
Published: August 2024

Abstract: This article discusses strategies for leaders to foster an organizational culture of innovation. Innovation requires certain environmental and psychological conditions, namely psychological safety, autonomy, flexibility, and access to resources. Leaders must establish these enabling factors to allow creative ideas to flourish. They should also cultivate a growth mindset among employees by emphasizing learning over fixed abilities. Practices like communication, coaching, and recognition systems can shape mindsets. Additionally, leaders should actively engage employees in the innovation process through crowdsourcing platforms, cross-functional projects, hackathons, and senior leadership involvement. Storytelling, recognition events, and communicating impacts keeps innovation visible and motivates participation. The article presents case studies of companies like Atlassian, Toyota, and Kaiser Permanente that have successfully operationalized these strategies. It argues that nurturing creativity from within inspires new strategies and positions organizations to embrace disruption.

Importance of vegetation for manganese cycling in temperate forested watersheds

Published: January 2015

Many surface soils are enriched in metals due to anthropogenic atmospheric inputs. To predict the persistence of these contaminants in soils, factors that impact rates of metal removal from soils into streams must be understood. Experiments at containerized seedling (mesocosm), pedon, and catchment scales were used to investigate the influence of vegetation on manganese (Mn) transport at the Susquehanna/Shale Hills Critical Zone Observatory (SSHCZO) in Pennsylvania, USA, where past atmospheric inputs from industrial sources have enriched Mn in surface soils. Large quantities of Mn that were leached from soil components into solution were taken up by vegetation; as a result, only relatively small quantities of Mn were removed from soil into effluent and streams. Manganese uptake into vegetation exceeded Mn losses in soil leachate by 20–200X at all scales, and net Mn loss from soils decreased in the presence of vegetation due to uptake into plant tissues. The majority of Mn taken up by forest vegetation at SSHCZO each year was returned to the soil in leaf litter and consequently immobilized as Mn oxides that formed during litter decomposition. Thus, plant uptake of Mn combined with rapid oxidation of Mn during litter decomposition contribute to long‐term retention. Current release rates of soluble Mn from SSHCZO soils were similar to release rates from the larger Susquehanna River Basin, indicating that the processes observed at SSHCZO may be widespread across the region. Indeed, although atmospheric deposition of Mn has declined, surface soils at SSHCZO and throughout the eastern United States remain enriched in Mn. If recycling through vegetation can attenuate the removal of Mn from soils, as observed in this study, then Mn concentrations in soils and river waters will likely decrease slowly over time following watershed contamination. Understanding the role of vegetation in regulating metal transport is important for evaluating the long‐term effects of historical and ongoing metal loading to soils.
Assessing the controllability of Arctic sea ice extent by sulfate aerosol geoengineering

Published: January 2015

In an assessment of how Arctic sea ice cover could be remediated in a warming world, we simulated the injection of SO2 into the Arctic stratosphere making annual adjustments to injection rates. We treated one climate model realization as a surrogate “real world” with imperfect “observations” and no rerunning or reference to control simulations. SO2 injection rates were proposed using a novel model predictive control regime which incorporated a second simpler climate model to forecast “optimal” decision pathways. Commencing the simulation in 2018, Arctic sea ice cover was remediated by 2043 and maintained until solar geoengineering was terminated. We found quantifying climate side effects problematic because internal climate variability hampered detection of regional climate changes beyond the Arctic. Nevertheless, through decision maker learning and the accumulation of at least 10 years time series data exploited through an annual review cycle, uncertainties in observations and forcings were successfully managed.
Self‐Limited Switching in Ta2O5/TaOx Memristors Exhibiting Uniform Multilevel Changes in Resistance
Authors: Kim Kyung Min , Lee Seung Ryul , Kim Sungho , Chang Man , Hwang Cheol Seong
Published: January 2015

To facilitate the development of memristive devices, it is essential to resolve the problem of non‐uniformity in switching, which is caused by the random nature of the filamentary switching mechanism in many resistance switching memories based on transition metal oxide. In addition, device parameters such as low‐ and high‐state resistance should be regulated as desired. These issues can be overcome if memristive devices have switching limits for both the low‐ and high‐resistance states and if their resistance values are highly controllable. In this study, a method termed self‐limited switching for uniformly regulating the values of both the low‐ and high‐resistance states is suggested, and the circuit configuration required for the self‐limited switching is established in a Ta2O5/TaOx memristive structure. A method of improving the uniformity of multi‐level resistance states in this memristive system is also proposed.
Mesoporous Colloidal Superparticles of Platinum‐Group Nanocrystals with Surfactant‐Free Surfaces and Enhanced Heterogeneous Catalysis
Authors: Hu Yongxing , Liu Yuzi , Sun Yugang
Published: January 2015

Synthesis of colloidal superparticles (CSPs) of nanocrystals, a class of assembled nanocrystals in the form of colloidal particles, has been emerging as a new frontier in the field of nanotechnology because of their potential novel properties originated from coupling of individual nanocrystals in CSPs. Here, a facile approach is reported for the controlled synthesis of mesoporous CSPs made of various platinum‐group nanocrystals that exhibit high colloidal stability and ligand‐free surfaces to significantly benefit their applications in solution‐phase heterogeneous catalysis. The synthesis relies on self‐limiting growth of composite particles through coprecipitation of both Pt‐group nanocrystals (or their precursor compounds) and silver halides on sacrificial substrates of colloidal silver particles. The intermediate silver halides in the composite particles play the critical role in limiting the continuous growth (and/or coalescence) of individual Pt‐group nanocrystals and they can be selectively dissolved to create nanoscale pores in the resulting CSPs.

Published: January 2015

Dielectric elastomer actuators (DEA) are smart lightweight flexible materials integrating actuation, sensing, and structural functions. The field of DEAs has been progressing rapidly, with actuation strains of over 300% reported, and many application concepts demonstrated. However many DEAs are slow, exhibit large viscoelastic drift, and have short lifetimes, due principally to the use of acrylic elastomer membranes and carbon grease electrodes applied by hand. Here a DEA‐driven tunable lens, the world's fastest capable of holding a stable focal length, is presented. By using low‐loss silicone elastomers rather than acrylics, a settling time shorter than 175 μs is obtained for a 20% change in focal length. The silicone‐based lenses show a bandwidth 3 orders of magnitude higher compared to lenses of the same geometry fabricated from the acrylic elastomer. Stretchable electrodes, a carbon black and silicone composite, are precisely patterned by pad‐printing and subsequently cross‐linked, enabling strong adhesion to the elastomer and excellent resistance to abrasion. The lenses operate for over 400 million cycles without degradation, and show no change after more than two years of storage. This lens demonstrates the unmatched combination of strain, speed, and stability that DEAs can achieve, paving the way for complex fast soft machines.

First reported by Farnum as much as 40 years ago, diketopyrrolopyrroles (2,5‐dihydropyrrolo[4,3‐c]pyrrolo‐1,4‐diones) are currently one of the most widely used dyes, with applications that span high‐quality pigments, field‐effect transistors, bulk‐heterojunction solar cells, dye‐sensitized solar cells, and fluorescence imaging. Due to the breadth of their utility, there have been several focused reviews on this topic since 1988. Considering the growing importance of these dyes, this review describes the overall progress made in four decades in both synthesis and the elucidation of their reactivity, and offers a critical comparison of various methods reported in the literature. The relationship between their structure and optical properties is also reviewed in detail. The extension of diketopyrrolopyrroles' chromophore leads to a significant change in both linear and nonlinear optical properties. A very strong bathochromic shift in the absorption and an increase in the two‐photon absorption cross‐section are typical for these analogues. Straightforward synthesis combined with good stability and a near‐unity fluorescence quantum yield ensures that diketopyrrolopyrroles will continue to attract attention for years to come. The goal of this review is to systematize knowledge on these dyes, enabling their use in more real‐world applications.

Silane derivatives with wide energy gap (≈3.5 eV) containing different electron‐withdrawing groups of quinoline and naphthyridine are synthesized and used as the electron transporting materials. The different electron transporting and hole/exciton blocking properties of the silane derivatives are investigated via multilayered structure of organic electrophosphorescent devices by using fac‐tris(2‐phenylpyridine)iridium (Ir(ppy)3) as the phosphorescent emitter. 15.4% of maximum external quantum efficiency (EQE) corresponding to 56.2 cd A−1 of maximum current efficiency is obtained with a maximum power efficiency of 58.9 lm W−1 by employing di‐(4‐(1,8‐naphthyridin‐2‐yl)phenyl)diphenylsilane (DNPS) as the electron transporting material, combining with 2,9‐dimethyl‐4,7‐diphenyl‐1,10‐phenanthroline as the hole blocking layer, which is higher than the performance of conventional Alq3 device. When changing naphthyridine of DNPS to the electron‐withdrawing group of quinoline (di‐(4‐(isoquinolin‐4‐yl)phenyl)diphenylsilane), only 11.4% of maximum EQE with 41.4 cd A−1 of maximum current efficiency and 32.5 lm W−1 of a maximum power efficiency is obtained. These indicate that the electron transporting ability increases while the electron‐withdrawing group changes from quinoline to naphthyridine, which is also consistent with the calculated reorganization energy.

Genome‐wide association studies (GWAS) hold tremendous promise to improve our understanding of human biology. Recent GWAS have revealed over 75 loci associated with erythroid traits, including the 4q27 locus that is associated with red blood cell size (mean corpuscular volume). The close linkage disequilibrium block at this locus harbors the CCNA2 gene that encodes cyclin A2. CCNA2 mRNA is highly expressed in human and murine erythroid progenitor cells and regulated by the essential erythroid transcription factor GATA1. To understand the role of cyclin A2 in erythropoiesis, we have reduced expression of this gene using short hairpin RNAs in a primary murine erythroid culture system. We demonstrate that cyclin A2 levels affect erythroid cell size by regulating the passage through cytokinesis during the final cell division of terminal erythropoiesis. Our study provides new insight into cell cycle regulation during terminal erythropoiesis and more generally illustrates the value of functional GWAS follow‐up to gain mechanistic insight into hematopoiesis.Am.

In the Roman period, urban and rural ways of living were differentiated philosophically and legally, and this is the first regional study of these contrasting life‐ways. Focusing on frailty and mortality risk, we investigated how these differed by age, sex, and status, using coffin type as a proxy for social status. We employed skeletal data from 344 individuals: 150 rural and 194 urban (1st–5th centuries A.D.) from Dorset, England. Frailty and mortality risk were examined using indicators of stress (cribra orbitalia, porotic hyperostosis, nonspecific periostitis, and enamel hypoplastic defects), specific metabolic and infectious diseases (rickets, scurvy, and tuberculosis), and dental health (carious lesions and calculus). These variables were studied using Chi‐square, Siler model of mortality, Kaplan–Meier analysis, and the Gompertz model of adult mortality. Our study found that overall, mortality risk and survivorship did not differ between cemetery types but when the data were examined by age, mortality risk was only significantly higher for urban subadults. Demographic differences were found, with urban cemeteries having more 0–10 and >35 year olds, and for health, urban cemeteries had significantly higher frequencies of enamel hypoplastic defects, carious lesions, and rickets. Interestingly, no significant difference in status was observed between rural and urban cemeteries. The most significant finding was the influence of the skeletal and funerary data from the Poundbury sites, which had different demographic profiles, significantly higher frequencies of the indicators of stress and dental health variables. In conclusion, there are significant health, demographic, and mortality differences between rural and urban populations in Roman Britain.

Published: January 2015

Pickering‐Emulsionen sind tensidfreie Dispersionen von zwei nicht mischbaren Flüssigkeiten, die durch Kolloidpartikel stabilisiert werden. Diese Systeme sind ökologisch besonders interessant, weil hiermit Reaktionen tensid‐ und lösungsmittelfrei durchgeführt werden können. Die kolloidstabilisierten Emulsionen unterscheiden sich in ihren Eigenschaften deutlich von tensidstabilisierten Emulsionen, Mikroemulsionen und micellaren Systemen. Trotz dieser spezifischen Vorteile sind die Anwendungsmöglichkeiten von Pickering‐Emulsionen noch wenig erforscht. In diesem Kurzaufsatz werden neue amphiphile Hybridmaterialien und Komposite für Grenzflächenkatalysatoren in Pickering‐Emulsionen beschrieben. Ein besonderer Fokus liegt dabei auf dem Einsatz in industrierelevanten Zweiphasenreaktionen zur Synthese von Feinchemikalien, Biokraftstoffveredelung und Dekontamination.

An efficient catalytic system using 1‐benzyl‐4‐aza‐1‐azoniabicyclo[2.2.2]octane chloride and PdCl2 was developed for the cross‐coupling reaction of arylboronic acids with acyl chlorides. The catalytic amount of this homogeneous catalytic system affords the corresponding diaryl and alkyl aryl ketones in good to excellent yields under mild reaction conditions.
