Job satisfaction is a pleasurable tendency towards an individual’s job. It enables one to realize his/her maximum potential to accomplish organizational goals productively. There is a strong correlation between job satisfaction and leadership, absenteeism, turnover, exhaustion, physical and psychological well-being, content life, productivity personality, and organizational citizenship. The world's top educational organizations view it as being extremely important for development. This cross-sectional comparative study focuses on the impact of achievement, altruism, autonomy, comfort, safety, and status gender-wise on the job satisfaction of the teachers of private secondary schools in Karachi. The Statistical Package for the Social Sciences (SPSS) 25 was used for the data analysis of the study. There were (n=210) teachers of private secondary schools who participated in the study. An independent sample t-test about the comparison between the JS level on its six dimensions of the male and female teachers working in private secondary schools in Karachi. The analysis of the data showed significant differences. The study's findings revealed that male and female teachers had significantly different degrees of job satisfaction associated with various facets. The female teachers were much more satisfied than the male teachers in success, altruism, autonomy, comfort, safety, and status.

The Cuban Music Room is a pilot low-tech immersive music system designed by an Anglo-Cuban team working in Matanzas, Cuba. It allows viewers to experience a performance of Cuban rumba in its home setting: an inner city tenement yard in Matanzas, Cuba. The approach to capture changes the traditional roles of the cinematographer and subjects, allowing the musicians control over the outputs. The viewing format allows audience members to set their own subject-position, choosing what they hear and see at any point in the performance while interacting with other viewers. The format has potential for both museum and educational applications.

Electronic Knowings
Authors: Gough-Brady Catherine , Rogers Christine
Published: December 2022

Through short essay films, Christine Rogers and Catherine Gough-Brady, creative practice researchers and filmmakers, attempt to collaborate with each other and the theories of ethnographers and documentarians David and Judith MacDougall. Christine and Catherine use the writing and films of the MacDougall’s as prompts to turn their attention to the processes of filming. Christine speaks to how holding the camera viewfinder to her face can manufacture belonging, and at other times, provide welcome distancing. Catherine explores observational filmmaking as a methodology that can applied to other endeavours, for instance academia. Alongside this, Catherine uses this film to explore how to create a visual dialogue (or collaboration) between filmic elements within the film. Because of their divergent responses the final works by Christine and Catherine become related rather than collaborative. They reveal that this may result from them both allowing research questions to arise as part of their independent creative processes, rather than being set at the outset.

Published: December 2022

В статье рассматривается определение суммарных нелинейных сил и соответствующих амплитуд второго порядка различных видов качки на основании применения трехмерной потенциальной теории. Проведена оценка влияния отдельных составляющих нелинейных сил в суммарном силовом воздействии на судно. Выполнено сравнение расчетов амплитудно-частотных характеристик второго порядка с расчетами по различным двумерным методам. Показано хорошее согласование результатов между собой в большинстве случаев. Показано, что влияние нелинейных сил приводит к появлению супергармонических резонансных режимов вертикальной, бортовой и килевой качки, имеющих место в зоне частот в два раза меньших соответствующих собственных частот. Приведены результаты расчетов амплитуд вторых гармоник на различных курсовых углах. Показано, что наибольшее влияние нелинейные факторы имеют место при расположении судна лагом. Приведены результаты расчетов амплитудно-частотных характеристик поперечных видов качки с учетом нелинейных факторов. Показано их значительное влияние в зоне низких частот.

The article considers the determination of the total nonlinear forces and the corresponding amplitudes of the second order of various types of motions based on the application of three-dimensional potential theory. An assessment of the influence of individual components of nonlinear forces in the total force effect on the ship was carried out. The calculations of the amplitude-frequency characteristics of the second order are compared with the calculations by various two-dimensional methods. Good agreement between the results was shown in most cases. It is shown that the influence of non-linear forces leads to the appearance of superharmonic resonant modes of heave, roll and pitch modes of motions occurring in the frequency zone twice as low as the corresponding natural frequencies. The results of calculations of the amplitudes of the second harmonics at different heading angles are presented. It is shown that the greatest influence of non-linear factors takes place during the motions in beam waves. The results of calculations of the amplitude-frequency characteristics of transverse types of motions are given, taking into account non-linear factors. Their significant influence in the low frequency zone is shown.
Method for calculating the vibration isolation of a marine diesel generator set, taking into consideration the influence of thrust onboard, bow and stern vibration isolators

Published: December 2022

Статья является обобщением ранее выполненных работ mamsar и рассматривает методику расчета амортизации судовой электростанции на примере СДГА-500 с неуравновешенным приводным дизелем 5ЧН 25/30 с учетом влияния упорных бортовых, носовых и кормовых виброизоляторов. Расчеты амортизации СДГА усложняются, если приводной дизель неуравновешенный, а упорные виброизоляторы относительно несущей рамы установлены без зазоров. Целью представленной методики является исследование влияния упорных виброизоляторов на эффективность виброизоляции общей системы амортизации и обоснование необходимости расчета амортизации СДГА с учетом влияния упорных виброизоляторов. Методика расчета амортизации предусматривает порядок представления: схем опорной и упорной систем амортизации с соответствующими компонентами; исходных данных; последовательности расчетов амортизации по двум вариантам – без учета и с учетом влияния упорных виброизоляторов и построения частотных диаграмм. Частоты свободных колебаний без учета влияния упорных виброизоляторов на 30–54% меньше значений, соответствующих частотам с учетом влияния упорных виброизоляторов, что свидетельствует о целесообразности расчета амортизации агрегата с учетом влияния упорных виброизоляторов.

The article is a generalization of MAMSAR's previously performed work and examines the methodology for calculating the vibration isolation of a ship's power plant using the example of SDGA-500 with an unbalanced 5CHN 25/30 drive diesel engine, taking into account the influence of thrust on-board, bow and stern vibration isolators. Calculations of SDGA vibration isolation become more complicated if the drive diesel is unbalanced, and the thrust vibration isolators relative to the load-bearing frame are installed without gaps. The purpose of the presented methodology is to study the effect of persistent vibration isolators on the effectiveness of vibration isolation of the general suspention system and substantiate the need to calculate the depreciation of the SDGA taking into account the influence of persistent vibration isolators. The vibration isolation calculation methodology provides for the presentation of: schemes of the support and thrust suspention systems with the corresponding components; initial data; the sequence of vibration isolation calculations according to two options – without and taking into account the influence of thrust vibration isolators and the construction of frequency diagrams. The frequencies of free vibrations, without taking into account the influence of persistent vibration isolators, are 30–54% less than the values of the corresponding frequencies, taking into account the influence of persistent vibration isolators, which indicates the expediency of calculating the vibration isolation of the unit, taking into account the influence of persistent vibration isolators.

Повышение безопасности судов в штормовых условиях при наличии зарываемости носовой оконечности, когда может произойти её захват волной, сопряжено с необходимостью определения гидродинамических сил и моментов, возникающих в носовой оконечности судна и оценки влияния на их величину конструктивных элементов носовой части судна, в частности, фальшборта. В настоящей работе для исследования динамики взаимодействия носовой оконечности судна с внешней средой использовался метод SPH. Выполнена оценка гидродинамических сил, действующих на носовую оконечность в направлении обтекания и в поперечном направлении, показавшая, что их величина может быть весьма существенной и представлять опасность с точки зрения обеспечения безопасности мореплавания. Исследовано изменение гидродинамических сил и моментов, действующих на носовую оконечность, в зависимости от угла крена судна а также геометрических характеристик фальшборта. Показано существенное влияние главных размерений и условий загрузки судна, а также фальшборта и его характеристик, на величину гидродинамических сил и кренящих моментов, действующих на носовую оконечность судна в условиях ее зарываемости в волну.

Improving the safety of ships in stormy conditions in the presence of burrowing of the bow, when it can be captured by a wave, is associated with the need to determine the hydrodynamic forces and moments that arise in the bow of the ship and assess the impact on their magnitude of the structural elements of the bow of the ship, in particular, the bulwark. In this work, the SPH method was used to study the dynamics of the interaction of the bow of the ship with the external environment. An assessment of the hydrodynamic forces acting on the bow in the flow direction and in the transverse direction has been carried out, showing that their magnitude can be very significant and pose a danger from the point of view of ensuring the safety of navigation. The change in hydrodynamic forces and moments acting on the bow is investigated, depending on the roll angle of the vessel and the geometric characteristics of the bulwark. A significant influence of the main dimensions and loading conditions of the vessel, as well as the bulwark and its characteristics, on the magnitude of hydrodynamic forces and heeling moments acting on the bow end of the vessel in the conditions of its burrowing into a wave.

Published: December 2022

The field of digital forensics has become commonplace due to the increasing prevalence of technology since the late 20th century and the inevitable relevance of this technology in the conducting of criminal activity. In traditional forensics, the evidence is generally something tangible that could identify the criminal, such as hair, blood or fingerprints. In contrast, digital forensics deals with files and data in digital form extracted from digital devices like computers, and phones, among other digital devices, meaning is derived from the fact that a computer or computerised device is the subject or object of crime. In this paper, we explore the challenges faced by the National Identification and Registration Authority (NIRA) digital forensic investigation and develop a process model that enhances the accuracy of digital forensic investigation. We adopted a mixed method approach of research involving qualitative, quantitative and experimental design. The study makes significant findings in areas of enhancement accuracy of digital forensic investigation by enumerating the processes that must be followed. As a recommendation for future work, for purposes of generalisation of the study findings, a wider study involving other security agencies such as the police should be conducted.

Charging Our Electrical Devices in Anywhere and at Any time
Authors: Shun Lam Kai
Published: December 2022

Being able to charge electronic devices anywhere is a modern-day problem. That said, ‘Made in China’ external charging devices can solve this problem to some extent. However, these de- vices are often poor quality and can be a fire hazard. To address this issue, the author suggests using an electromagnetic spread spectrum, which is highly related to harvesting electrical energy from clean, renewable energy sources, and then transmitted to charge all types of electrical devices. By applying this author’s proposed probability-random variables assignment — each type of electromagnetic wave is associated with a spe-cial channel with a centralized management information system controlled in the background. Such de-sign can avoid EM-wave interference and encourage a delicate (or special) channel for energy transmit-ting. Hence, it can solve electrical devices charging problem or one may get the device charged anywhere and anytime. Furthermore, with a professional electronic circuit de- sign, together with meta-materials coated on the surface of a set antenna block, 90–100% of harvested renewable-clean energy might be transmitted. There is an alternative way of charging by using induc- tive coils; however, there are some defects in such case. Further advance is the introduction of electro- magnetic wormhole which can shield human beings from the influence of magnetic flux outside the tunnel during charging

Published: December 2022

The global energy crisis affects all of us. With a growing global population and finite fossil fuel supplies, we must find new energy sources. Alternative energy sources must be prioritized. Biofuels like biodiesel, biohydrogen, biomethanol, and bioethanol have come a long way in recent decades. These alternative fuels are from low-cost, renewable sources like algal, microbial, and plant biomass. Several governments, including India, are improving their renewable energy production capabilities. The main obstacles to rapid biofuel adoption are time and cost. For biofuel to truly become a viable alternative to fossil fuels, nanotechnology has recently provided the much-needed impetus. Nanomaterials' unique structural behavior, such as small size (nanoscale size), has increased their use in biofuel production. It improves efficiency and reduces the time required to convert waste into biofuels. This review addresses the latest information on various types of nanoparticles, and challenges faced and the future prospects of emerging applications of nanoparticles in biofuel production.

Close Trans-Neptunian Object Passages as a Driver of the Origin and Evolution of Ultrawide Kuiper Belt Binaries
Authors: Campbell Hunter M. , Stone Lukas R. , Kaib Nathan A.
Published: December 2022

Within the dynamically cold low-inclination portion of the Classical Kuiper Belt, there exists a population of weakly bound binary systems with a number of unusual properties, most notable of which is their extremely wide orbital separations—beyond 7% of their Hill radii. The stability and evolution of these ultrawide Trans-Neptunian binaries (TNBs) have, in the past, been studied extensively under the assumption that the primary evolving mechanisms are interactions between the binary components and impacting Trans-Neptunian Objects (TNOs). Here, we instead study their evolution as driven by the gravitational perturbations of close passing but nonimpacting TNOs. By simulating these passages, we show that the aggregate effects of encounters over billions of years have a significant effect on Kuiper Belt binary evolution. Such processes can lead to tight binaries widening significantly over time, approaching and sometimes surpassing the separation of the widest known TNBs. We also find that the eccentricity and inclination distributions of observed ultrawide TNBs can be sampled from such widened binaries. While we are unable to produce enough wide binaries to explain their abundance, the orbital properties of ones we do produce are consistent with known wide binaries.
A Red Giants’ Toy Story
Authors: Miller Bertolami Marcelo M.
Published: December 2022

In spite of the spectacular progress accomplished by stellar evolution theory, some simple questions remain unanswered. One of these questions is “Why do stars become red giants?”. Here we present a relatively simple analytical answer to this question. We validate our analysis by constructing a quantitative toy model of a red giant and comparing its predictions to full stellar evolutionary models. We find that the envelope forces the value of

at, and above, the burning shell into a very narrow range of possible values. Together with the fact that the stellar material at the burning shell both provides and transports most of the stellar luminosity, this leads to tight relations between the thermodynamic variables at the burning shell and the mass and radius of the core—T

We show that for all stellar masses evolution leads to an increase in the pressure and density contrasts between the shell and the core, forcing a huge expansion of the layers on top of the burning shell. Besides explaining why stars become red giants our analysis also offers a mathematical demonstration of the so-called shell homology relations, and provides simple quantitative answers to some properties of low-mass red giants.
SPYGLASS. III. The Fornax–Horologium Association and Its Traceback History within the Austral Complex
Authors: Kerr Ronan , Kraus Adam L. , Murphy Simon J. , Krolikowski Daniel M. , Bedding Timothy R. , Rizzuto Aaron C.
Published: December 2022

The study of young associations is essential for building a complete record of local star formation processes. The Fornax–Horologium association (FH), including the χ
1 Fornacis cluster, represents one of the nearest young stellar populations to the Sun. This association has recently been linked to the Tuc-Hor, Carina, and Columba associations, building an extensive “Austral Complex” almost entirely within 150 pc. Using Gaia astrometry and photometry in addition to new spectroscopic observations, we perform the deepest survey of FH to date, identifying over 300 candidate members, nearly doubling the known population. By combining this sample with literature surveys of the other constituent populations, we produce a contiguous stellar population covering the entire Austral Complex, allowing the definitions of subpopulations to be reassessed along with connections to external populations. This analysis recovers new definitions for FH, Tuc-Hor, Columba, and Carina, while also revealing a connection between the Austral complex and the Sco-Cen-affiliated Platais 8 cluster. This suggests that the Austral complex may be just a small component of a much larger and more diverse star formation event. Computing ages and tracing stellar populations back to formation reveals two distinct nodes of cospatial and continuous formation in the Austral Complex, one containing Tuc-Hor, and the other containing FH, Carina, and Columba. This mirrors recent work showing similar structure elsewhere, suggesting that these nodes, which only emerge through the use of traceback, may represent the clearest discrete unit of local star formation, and a key building block needed to reconstruct larger star-forming events.
Solar Polar Magnetic Fields: Comparing Full-disk and High-resolution Spectromagnetograph Data
Authors: Petrie Gordon J. D.
Published: December 2022

This is the first systematic comparison between photospheric polar magnetic field data from a full-disk synoptic observing program, the National Solar Observatory’s Synoptic Optical Long-term Investigations of the Sun Vector Spectromagnetograph (SOLIS/VSM), and a high-resolution vector spectromagnetograph, the Hinode Solar Optical Telescope Spectropolarimeter (SOT/SP). Polar magnetic fluxes derived from longitudinal magnetic field measurements from both telescopes and from SOT/SP full-Stokes vector data are all compared in the form of polar synoptic maps. Measurements taken over 35 day periods with advantageous rotation axis tilt angle are used; observations extend to the poles, and no synthetic pole-filling is needed. Polar fluxes are derived from longitudinal data assuming an approximately radial field, whereas those derived from vector data are based on measured vector magnitude and direction. However, the full-vector measurements may have a detection problem: polar fields are observed as mostly transverse from (near) Earth, and Zeeman sensitivity to transverse fields is significantly lower than for longitudinal fields. Accordingly, the SOT/SP vector-based polar fluxes are lower than the longitudinal-based fluxes from both telescopes, a result driven by pixels without sufficient Q and U signals for the full-Stokes inversions to detect significant radial field but with good Stokes V signal implying a significant field. Furthermore, the SOT/SP longitudinal-based fluxes are significantly higher than their VSM counterparts because of superior seeing-free spatial resolution and longer observation time. The SOT/SP longitudinal-based polar fluxes appear large enough to account for radial interplanetary field measurements whereas the SOT/SP vector-based and the VSM ones are generally too low.
V5856 Sagittarii/2016: Broad Multiepoch Spectral Coverage of a Sustained High-luminosity Nova

Published: December 2022

Nova V5856 Sagittarii is unique for having remained more than nine magnitudes above its pre-outburst brightness for more than 6 yr. Extensive visible and infrared (IR) spectra from the time of outburst to the present epoch reveal separate emitting regions with distinct spectral characteristics. Permitted emission lines have both broad and narrow components, whereas the forbidden line profiles are almost entirely broad. The permitted line components frequently display P Cygni profiles indicating high optical depth, whereas the broad components do not show detectable absorption. The densities and velocities deduced from the spectra, including differences in the O i
λ7773 and λ8446 lines, are not consistent with an ongoing wind. Instead, the prolonged high luminosity and spectral characteristics are indicative of a post-outburst common envelope that enshrouds the binary, and is likely the primary source of the visible and IR emission.
Biodiversity of Coleoptera (Insecta) in Mordovia State Nature Reserve (Russia) using fermental traps

Published: December 2022

Protected areas are unique ecosystems that are minimally affected by anthropogenic activities. Therefore, in many cases, they are refugia and relevance of faunistic research is undeniable here. A simple method of catching insects, such as trapping with the help of fermental traps, was used in this area for the first time. The authors of the dataset used this method from 2018 to 2021. One thousand and fifty-one traps of our own design were installed. The dataset includes data on 367 species from 52 families (6,497 records of 44,600 specimens). Ten species were dominant in the traps (Cryptarcha strigata, Protaetia marmorata, Glischrochilus grandis, Glischrochilus hortensis, Soronia grisea, Rhagium mordax, Leptura thoracica, Leptura quadrifasciata, Quedius dilatatus and Protaetia fieberi). These species accounted for 76.9% of all individuals in the total amount of captured specimens. Cryptarcha strigata was the most numerous species (28.8% of the total) and the most frequently encountered species (64.9%). The greatest species diversity was recorded in the families Cerambycidae (53 species), Elateridae and Curculionidae (39 species each), Nitidulidae and Coccinellidae (22 species each). The dataset contains information on the occurrence of 15 rare species.

We have recently published a checklist of the Coleoptera of Mordovia State Nature Reserve (Egorov et al. 2020). It included 2,145 species from 88 families. However, the published list did not contain information about the occurrence of various species of beetles, especially caught in recent years. Part of this list contained information about species collected using fermental traps. However, the list of species did not provide information about specific locations.

Background: Members of editorial boards of academic journals are often considered gatekeepers of knowledge and role models for the academic community. Editorial boards should be sufficiently diverse in the background of their members to facilitate publishing manuscripts representing a wide range of research paradigms, methods, and cultural perspectives.

Objectives: To critically evaluate changes in the representation of binary gender and geographic diversity over time on the editorial boards of Chemical Geology and Geochimica et Cosmochimica Acta, flagship geochemistry journals, respectively, from the European Association of Geochemistry and the Geochemical Society – Meteoritical Society partnership.

Methods: The composition of editorial boards was ascertained as given in the first issue of each year, over 1965–2021 for Chemical Geology and 1950–2021 for Geochimica et Cosmochimica Acta, and members of the editorial boards were coded for their country of affiliation (the country of origin may have been different) and for their binary gender.

Results: Gender parity, limited to men and women, and the number of countries of affiliation increased steadily between the late 1980s and 2021. However, the geographic distribution remained dominated by affiliations from North America and Western Europe. The editor-in-chief or board of editors had a significant impact on the diversity of the editorial boards, and both geographic and gender diversity may evolve with nearly every newly appointed editor. However, the persistently substantial under-representation on editorial boards of affiliations outside North America and Europe is of concern and needs to be the focus of active recruitment and ongoing monitoring. This approach will ensure that traditionally low geographic diversity is increased and maintained in the future.

Conclusion: Improving diversity and inclusion of editorial boards of academic journals and strengthening journal and disciplinary reputations are mutually reinforcing. Instituting a rotating editorship with emphasis on embedding broader geographic networks and more equitable international recruitment could ensure sustained and wider geographic representation and gender balance of editorial boards and promote originality and quality of published research, representing our global communities.
Should editors with multiple retractions or a record of academic misconduct serve on journal editorial boards?
Authors: Teixeira da Silva Jaime A.
Published: December 2022

In the academic world, despite their corrective nature, there is still a negative stigma attached to retractions, even more so if they are based on ethical infractions. Editors-in-chief and editors are role models in academic and scholarly communities. Thus, if they have multiple retractions or a record of academic misconduct, this viewpoint argues that they should not serve on journals’ editorial boards. The exception is where such individuals have displayed a clear path of scholarly reform. Policy and guidance is needed by organizations such as the Committee on Publication Ethics.

Canals provide wide-ranging economic benefits, while also serving as corridors for the introduction and spread of aquatic alien species, potentially leading to negative ecological and economic impacts. However, to date, no comprehensive quantifications of the reported economic costs of these species have been done. Here, we used the InvaCost database on the monetary impact of invasive alien species to identify the costs of those facilitated by three major canal systems: the European Inland Canals, Suez Canal, and Panama Canal. While we identified a staggering number of species having spread via these systems, monetary costs have been reported only for a few. A total of $33.6 million in costs have been reported from species linked to European Inland Canals (the fishhook waterflea Cercopagis pengoi and the zebra mussel Dreissena polymorpha) and $8.6 million linked to the Suez Canal (the silver-cheeked toadfish Lagocephalus sceleratus, the lionfish Pterois miles, and the nomad jellyfish Rhopilema nomadica), but no recorded costs were found for species facilitated by the Panama Canal. We thus identified a pervasive lack of information on the monetary costs of invasions facilitated by canals and highlighted the uneven distribution of costs.
The immatures of the New World treehopper tribes Acutalini Fowler and Micrutalini Haupt (Hemiptera, Membracidae, Smiliinae)
Authors: McKamey Stuart H. , Wallner Adam M.
Published: December 2022

The nymphs of Acutalis Fairmaire, Bordoniana Sakakibara, Thrasymedes Kirkaldy, and Micrutalis Fowler are described and illustrated (Bordoniana and Thrasymedes for the first time). The nymphs of all four genera are exceedingly cryptic. The nymphs of some species lack scoli on the head and pronotum but all have paired scoli on the meso- and metathoracic nota and abdominal segments III–IX. Some species also have lateral rows of enlarged chalazae on the abdomen, and even large scoli ventrolaterally—the latter condition is unique within Smiliinae. The eggs are deposited in stems (not in exposed masses) and nymphs are solitary and not ant-attended. The fifth instar nymphs of Micrutalini range in length from 3.0–3.5 mm, much smaller than the fifth instars of most other treehoppers.
