The Downside Effect of Emotional Intelligence on Job Stress Among Non-Academic University Staff

Behavioral science researchers and scholars have attempted to find effective elements that influence efficiency and effectiveness to improve organizational performance, as well as factors that contribute to job stress. Meanwhile, previous studies shows that by enhancing emotional intelligence, it can help individual to cope with stress, develop great relationships, empathize with others, and accomplish goals. Thus, this study aimed to examine the relationship between four types of emotional intelligence: self- emotion appraisal, other’s emotion appraisal, use of emotions, and regulation of emotion on job stress. A cross-sectional design method was used to employ a quantitative approach via a self-administered questionnaire with respondents were among the non-academic staff from a Malaysian public university. Interestingly, the results contradict to previous studies whereby all four types of emotional intelligence were positively associated to job stress with regulation of emotion being the main unique predictor to job stress. Specifically, the results indicate that the higher the individual’s emotional intelligence, the more prone they were to job stress. Thus, further explanation and implications of high emotional intelligence to one’s functioning has been discussed in this paper.
An Empirical Study of the Impact of Lockdown Measures on the Presumptive Taxation of Zimbabwe: A Case Study of ZIMRA

Following the health-care crisis caused by COVID-19, the Zimbabwean government, like many others across the world, imposed a lockdown. This had varying degrees of impact on various tax systems. This research paper examined the effects of lockdown measures on Zimbabwe's presumptive taxation. The study adopted a quantitative research approach, and semi-structured questionnaires were used to obtain detailed data. The results showed that COVID-19-induced lockdown restrictions impacted Zimbabwe Revenue Authority's (ZIMRA’s) presumptive tax collection and the livelihood of informal merchants. Many factors exacerbated the situation, one of which was the short notice in declaring lockdown enforcement. The informal traders indicated that the COVID-19 lockdown measures had a negative impact on their revenue generation and demand for their goods and services. The COVID-19-induced lockdown measures resulted in a drastic fall in presumptive tax collections in 2020. The study recommends that the Zimbabwean government assist small company owners, empower them and enable them to restart their operations. Furthermore, there is an urgent need to educate informal merchants about health hazards such as COVID-19, and support from the formal sector and international donors should ensure that informal traders such as vegetable vendors, cobblers, and transport operators have protective equipment as recommended by medical experts so that they can safely continue to be in business for them to be able to pay their presumptive taxes in time without fail.
The Earth's Equilibrium Climate Sensitivity and Thermal Inertia

The Earth's equilibrium climate sensitivity has received much attention because of its relevance and importance for global warming policymaking. This paper focuses on the Earth's \emph{thermal inertia time scale} which has received relatively little attention. The difference between the observed transient climate sensitivity and the equilibrium climate sensitivity is shown to be proportional to the thermal inertia time scale, and the numerical value of the proportionality factor is determined using recent observational data. Many useful policymaking insights can be extracted from the resulting empirical quantitative relation.
Jet-dominated quiescent states in black hole X-ray binaries: the case of V404 Cyg

The dynamical structure and radiative properties of the quiescent state (X-ray luminosity less than or similar to 10(34) erg s(-1)) of black hole X-ray transients (BHXTs) remain unclear, mainly because of low luminosity and poor data quantity. We demonstrate that the simultaneous multi-wavelength (including radio, optical, ultraviolet and X-ray bands) spectrum of V404 Cyg in its bright quiescent state can be well described by the radiation from the companion star and more importantly, the compact jet. Neither the outer thin disc nor the inner hot accretion flow is important in the total spectrum. Together with recent findings, i.e. the power-law X-ray spectrum and the non-variable X-ray spectral shape (or constant photon index) in contrast to the dramatic change in the X-ray luminosity, we argue the quiescent state spectrum of BHXTs is actually jet-dominated. Additional observational properties consistent with this jet model are also discussed as supporting evidence.
Stationarity of asymptotically flat non-radiating electrovacuum spacetimes

It is proven that a solution to the Einstein-Maxwell equations whose gravitational and electromagnetic radiation fields vanish at infinity is in fact stationary in a neighbourhood of spatial infinity. That is, if in adapted coordinates the Weyl and Faraday tensors decay suitably fast and there is an asymptotically-to-all-orders Killing vector field, then this is indeed a Killing vector field in the region outside the bifurcate horizon of a sphere of sufficiently large radius. In particular, electrovacuum time-periodic spacetimes, which are truly dynamical, do not exist. This can be interpreted as a mild form of the statement: “Gravitational waves carry energy away from an isolated system". This is an extension of earlier work by Alexakis and Schlue, and Bicak, Scholtz and Tod, to include matter/energy models, in this case electromagnetism. It is also shown that the same result holds when the Einstein's equations are coupled to a massless Klein-Gordon field.
Assessment of Oxidative Stress Indices in Tissues of Cadmium-challenged Female Wistar Rats Treated with Combined Ethanolic Leaf Extract of Manihot esculenta and Citrus sinensis

This research assessed the oxidative stress indices in tissues of cadmium-challenged female Wistar rats treated with combined ethanolic leaf extract of Manihot esculenta and Citrus sinensis. Eighteen female rats (150±20g) were divided put into three (3) groups: Group 1 (received feed and water only); Group 2 (received single dose of cadmium, 30mg/kg body weight at the start of the experiment) and Group 3 (received cadmium as in group 2 above and 200mg/kg body weight of combined extract of orange and cassava leaf, daily for two weeks). Cadmium load in the tissues of the rats were analyzed using AAS after acid digestion and oxidative stress indices were analyzed using standard procedures. Data obtained showed that the cadmium tissue load (𝑥̅±SD, μg/g tissue) were 0.005±0.0007 (liver), 0.007±0.0004 (kidney); 55.4±5.2 (liver), 28.3±4.6 (kidney); and 13.6±2.3 (liver), 20.7±2.5 (kidney) for Groups 1, 2 and 3 respectively. There was a higher concentration of Cd in the liver and kidney of rats exposed to Cd alone (Group 2) compared to the control (Group 1) and Cd-challenged rats treated with combined leaf extract of Manihot esculenta and Citrus sinensis (Group 3). Exposure to Cd alone caused significant (p<0.05) increase in lipid peroxidation and glutathione peroxidase in the liver and kidney compared to the control. Conversely, the administration of Cd alone to rats caused significant (p<0.05) reduction in the level of glutathione and the activities of superoxide dismutase and catalase compared to the control in both tissues. Significant amelioration was witnessed in all the parameters in Cd-challenged rats treated with the extract compared to rats challenged with Cd alone. The results show that Cd-induced oxidative stress can be countered effectively by combined leaf extract of Manihot esculenta and Citrus sinensis which is rich in antioxidant molecules.
Complement Regulation in Immortalized Fibroblast-like Synoviocytes and Primary Human Endothelial Cells in Response to SARS-CoV-2 Nucleocapsid Protein and Pro-Inflammatory Cytokine TNFα

Background: Case reports are available showing that patients develop symptoms of acute arthritis during or after recovery from SARS-CoV-2 infection. Since the interrelation is still unknown, our aim was to study the impact of the SARS-CoV-2 nucleocapsid protein (NP) on human fibroblast-like synoviocytes and human endothelial cells (hEC) in terms of complement and cytokine regulation. Methods: Non-arthritic (K4IM) synoviocyte, arthritic (HSE) synoviocyte cell lines and primary hEC were stimulated with recombinant NP and/or TNFα. Analyses of cell viability, proliferation, gene and protein expression of cytokines and complement factors were performed. Results: NP suppressed significantly the vitality of hEC and proliferation of HSE. NP alone did not induce any significant changes in the examined gene expressions. However, NP combined with TNFα induced significantly higher TNFα in HSE and K4IM as well as higher IL-6 and CD55 gene expression in HSE and suppressed C3aR1 gene expression in hEC. HSE proliferated twice as fast as K4IM, but showed significantly lesser gene expressions of CD46, CD55, CD59 and TNFα with significantly higher IL-6 gene expression. CD35 gene expression was undetectable in K4IM, HSE and hEC. Conclusions: NP might contribute in combination with other inflammatory factors to complement regulation in arthritis.
Magnetic and transport properties of rare-earth-based half-Heusler phases RPdBi: Prospective systems for topological quantum phenomena

RPdBi (R = Er, Ho, Gd, Dy, Y, Nd) compounds were studied by means of x-ray diffraction, magnetic susceptibility, electrical resistivity, magnetoresistivity, thermoelectric power and Hall effect measurements, performed in the temperature range 1.5-300 K and in magnetic fields up to 12 T. These ternaries, except diamagnetic YPdBi, exhibit localized magnetism of $R^{3+}$ ions, and order antiferromagnetically at low temperatures ($T_{N}$ = 2-13 K). The transport measurements revealed behavior characteristic of semimetals or narrow-band semiconductors. Both, electrons and holes contribute to the conductivity with dominant role of p-type carriers. The Hall effect of ErPdBi is strongly temperature and magnetic field dependent, reflecting complex character of the underlying electronic structures with multiple electron and hole bands. RPdBi, and especially DyPdBi, exhibit very good thermoelectric properties with a power factor coefficient $PF$ ranging from 6 to 20 $\mu$Wcm$^{-1}$K$^{-2}$.
Sleep Problems and Disabilities of the Arm, Shoulder, and Hand in Persons with Thoracic Outlet Syndrome—A Cross-Sectional Study

Thoracic outlet syndrome (TOS) arises as a result of a specific relationship among the anatomical structures that may cause compression in the muscles, nerves, and/or blood vessels in the neck, thereby compromising the local circulation. The aim of the current study was to establish the presence of sleep disturbance and disability in the shoulder, arm, and hand in individuals affected by TOS, as well as to ascertain if there are any differences in these findings relative to TOS-free individuals. The study sample comprised 82 TOS patients and 81 TOS-free individuals aged 19–66 years. Data were gathered by administering the Disabilities of the Arm, Shoulder, and Hand (DASH) and Pittsburgh Sleep Quality Index (PSQI) instruments. The results showed that both the DASH (t = −13.21, p < 0.001) and PSQI (t = −7.27, p < 0.001) scores obtained by the TOS group were higher relative to the controls and were strongly and positively correlated (ρ = 0.58, p < 0.01). As positive DASH scores may be indicative of TOS, they signal the need for further diagnostic evaluations. In individuals in whom TOS is already diagnosed, high DASH scores imply that further sleep quality assessments are required, as compromised sleep patterns may undermine quality of life.
**title** Asp Conference Series, Vol. **volume**, **publication Year** **editors** Host Galaxies of Agn

The relationship of an AGN to its host galaxy is a crucial question in the study of galaxy evolution. We perform stellar population synthesis in the central regions of galaxies of different activity levels. A large number of stellar features are measured both in the optical and near-infrared. We find the nuclear stellar population to be related to the level of activity. These differences are no more conspicuous further away in the bulge of the galaxy.
Coronal hole boundaries evolution at small scales - II. XRT view. Can small-scale outflows at CHBs be a source of the slow solar wind?

Aims. We aim to further explore the small-scale evolution of coronal hole boundaries using X-ray high-resolution and high-cadence images. We intend to determine the fine structure and dynamics of the events causing changes of coronal hole boundaries and to explore the possibility that these events are the source of the slow solar wind. Methods. We developed an automated procedure for the identification of transient brightenings in images from the X-ray telescope on-board Hinode taken with an Al Poly filter in the equatorial coronal holes, polar coronal holes, and the quiet Sun with and without transient coronal holes. Results. We found that in comparison to the quiet Sun, the boundaries of coronal holes are abundant with brightening events including areas inside the coronal holes where closed magnetic field structures are present. The visual analysis of these brightenings revealed that around 70% of them in equatorial, polar and transient coronal holes and their boundaries show expanding loop structures and/or collimated outflows. In the quiet Sun only 30% of the brightenings show flows with most of them appearing to be contained in the solar corona by closed magnetic field lines. This strongly suggests that magnetic reconnection of co-spatial open and closed magnetic field lines creates the necessary conditions for plasma outflows to large distances. The ejected plasma always originates from pre-existing or newly emerging (at X-ray temperatures) bright points. Conclusions. The present study confirms our findings that the evolution of loop structures known as coronal bright points is associated with the small-scale changes of coronal hole boundaries. The loop structures show an expansion and eruption with the trapped plasma consequently escaping along the "quasi" open magnetic field lines. These ejections appear to be triggered by magnetic reconnection, e.g. the so-called interchange reconnection between the closed magnetic field lines (BPs) and the open magnetic field lines of the coronal holes. We suggest that these plasma outflows are possibly one of the sources of the slow solar wind.
Microstructural characterization and properties of aluminium 7075/Mo prepared by microwave sintering for high-strength application

ABSTRACT Ceramic particulates are often used in reinforcement of aluminium alloys. The use of this particulates results in embrittlement and lowering of ductility. In tackling this, the present study involved the use of relatively ductile metal particles (molybdenum) as reinforcement. Molybdenum (Mo) powder was blended with Al-7075 powder at 4, 8 and 12 wt. %, compacted at 25 MPa, and microwave sintering was performed at 350, 450 and 550 °C. The effect of the variation in Mo dosage and sintering temperature on the phases, microstructure and properties was evaluated. The result showed varying phases and microstructural evolution in the composites. For all proportion of the Mo particles, 350 and 450 °C favoured porosity and sintered and relative densities, whereas 550 °C was detrimental to the properties. It was observed that 4 and 8 % Mo enhanced microhardness and tensile strength, while 12 % Mo showed a decrease in hardness and a strength. In the same way, sintering temperatures of 350 and 450 °C aided improvement in hardness and tensile strength, even as 550 °C exhibited lower property values. It was concluded that proportions of molybdenum not greater than 8 wt. % and sintering temperature not greater than 450 °C are suitable for property improvement.
RAPID TRANSITION OF UNCOMBED PENUMBRAE TO FACULAE DURING LARGE FLARES

In the past two decades, the complex nature of sunspots has been disclosed with high-resolution observations. One of the most important findings is the “uncombed” penumbral structure, where a more horizontal magnetic component carrying most of Evershed flows is embedded in a more vertical magnetic background. The penumbral bright grains are locations of hot upflows and dark fibrils are locations of horizontal flows that are guided by a nearly horizontal magnetic field. On the other hand, it was found that flares may change the topology of sunspots in δ configuration: the structure at the flaring polarity inversion line becomes darkened while sections of peripheral penumbrae may disappear quickly and permanently associated with flares. The high spatial and temporal resolution observations obtained with the Hinode/Solar Optical Telescope provide an excellent opportunity to study the evolution of penumbral fine structures associated with major flares. Taking advantage of two near-limb events, we found that in sections of peripheral penumbrae swept by flare ribbons the dark fibrils completely disappear, while the bright grains evolve into faculae that are signatures of vertical magnetic flux tubes. The corresponding magnetic fluxes measured in the decaying penumbrae show stepwise changes temporally correlated with the flares. These observations suggest that the horizontal magnetic field component of the penumbra could be straightened upward (i.e., turning from horizontal to vertical) due to magnetic field restructuring associated with flares, which results in the transition of penumbrae to faculae.
In‐Situ Monitoring of Interstellar Dust in the Inner Solar System

We present in this paper new interstellar dust data obtained in the inner solar system by the dust instruments on‐board the Cassini, Galileo and Helios spacecraft. While the Ulysses dust instrument provided an in‐situ monitoring of the interstellar dust stream at high ecliptic latitude between 3 AU and 5 AU, the new data cover an heliocentric distance range between 0.3 AU and 3 AU in the ecliptic plane. We show therefore in this paper the deep penetration of interstellar dust inside the Solar System. Furthermore, the data provide evidence of the interstellar dust stream alteration in the inner solar system, caused by radiation pressure forces and gravitation focusing.
Integrability of the η-deformed Neumann–Rosochatius model

An integrable deformation of the well-known Neumann–Rosochatius system is studied by considering generalised bosonic spinning solutions on the η-deformed AdS5×S5 background. For this integrable model we construct a 4×4 Lax representation and a set of integrals of motion that ensures its Liouville integrability. These integrals of motion correspond to the deformed analogues of the Neumann–Rosochatius integrals and generalise the previously found integrals for the η-deformed Neumann and (AdS5×S5)η geodesic systems. Finally, we briefly comment on consistent truncations of this model.
Two-dimensional kinematics of SLACS lenses – III. Mass structure and dynamics of early-type lens galaxies beyond z ≃ 0.1

We combine in a self-consistent way the constraints from both gravitational lensing and stellar kinematics to perform a detailed investigation of the internal mass distribution, amount of dark matter, and dynamical structure of the 16 early-type lens galaxies from the Sloan Lens ACS Survey (SLACS Survey), at z= 0.08-0.33, for which both Hubble Space Telescope/Advanced camera for Surveys and NICMOS high-resolution imaging and Very Large Telescope VIMOS integral-field spectroscopy are available. Based on this data set, we analyse the inner regions of the galaxies, that is, typically within one (three-dimensional) effective radius re, under the assumption of axial symmetry and by constructing dynamical models supported by two-integral stellar distribution functions. For all systems, the total mass density distribution is found to be well approximated by a simple power law ? (with m being the ellipsoidal radius): this profile is on average slightly super-isothermal, with a logarithmic slope = 2.074+0.043-0.041 (errors indicate the 68 per cent confidence interval) and an intrinsic scatter ? , and is fairly round, with an average axial ratio = 0.77 ± 0.04. The lower limit for the dark matter fraction (fDM) inside re ranges, in individual systems, from nearly zero to almost a half, with a median value of 12 per cent. By including stellar masses derived from stellar population synthesis models with a Salpeter initial mass function (IMF), we obtain an average fDM= 31 per cent, and the corresponding stellar profiles are physically acceptable, with the exception of two cases where they only marginally exceed the total mass profile. fDM rises to 61 per cent if, instead, a Chabrier IMF is assumed. For both IMFs, the dark matter fraction increases with the total mass of the galaxy (correlation significant at the 3σ level). Based on the intrinsic angular momentum parameter calculated from our models, we find that the galaxies can be divided into two dynamically distinct groups, which are shown to correspond to the usual classes of the (observationally defined) slow and fast rotators. Overall, the SLACS systems are structurally and dynamically very similar to their nearby counterparts, indicating that the inner regions of early-type galaxies have undergone little, if any, evolution since redshift z≈ 0.35.
Haematological and Serum Biochemical Profiles of Clarias gariepinus (Burchell, 1822) Fed Commercial and Farm-made Feeds

The present study was carried out to determine the haematological and serum biochemical profiles of Clarias gariepinus juveniles fed commercial and farm-made feeds and reared in intermediate bulk containers (IBC) tanks. Nine hundred juveniles (15.15±3.48g; 128.37± 9.67mm) were stocked in 09 IBC tanks (1m3) at a density of 100 fish/tank in triplicate and fed with imported extruded (Le), locally pelleted (Lpe) and locally extruded (Lex) feeds thrice a day to satiation for 16 weeks. At the end of the experiment, blood samples were collected from 10 fish/ dietary treatment to determine haematological and biochemical indices. Results revealed that Red Blood Cells Count, Packed Cell volume and Haemoglobin concentration were highest (p<0.05) in fish fed with “Le” feed while Mean Cell Haemoglobin Concentration, Mean Cell Haemoglobin, Mean Cell Volume, White Blood Cells Count, Lymphocytes, Monocytes, Granulocytes and Platelets showed no significant difference (p>0.05) among the dietary treatments. As for serum biochemistry, Total Cholesterol and Glucose were highest (p<0.05) in fish fed with “Le” feed while Total Protein, Alanine Transaminase, Aspartate Transaminase and Alkaline Phosphatase were significantly higher (p<0.05) in fish fed “Lpe” and “Lex” feeds. Conclusively, variation of dietary treatments was not detrimental to the health status of C. gariepinus reared in plastic IBC tanks.
