Why International Catch Shares Won't Save Ocean Biodiversity
Authors: Doremus Holly
Published: February 2022

Skepticism about the efficacy and efficiency of regulatory approaches has produced a wave of enthusiasm for market-based strategies for dealing with environmental conflicts. In the fisheries context, the most prominent of these strategies is the use of “catch shares,” which assign specific proportions of the total allowable catch to individuals who are then free to trade them with others. Catch shares are now in wide use domestically within many nations, and there are increasing calls for implementation of internationally tradable catch shares. Based on a review of theory, empirical evidence, and two contexts in which catch shares have been proposed, this Article explains why international catch shares are not likely to arrest the decline of ocean biodiversity. Catch shares were developed to promote greater economic efficiency and profitability in the fishing industry. They have proven capable of doing so at the domestic level, although their effects on wealth distribution have frequently been controversial. Theoretical and empirical support for the proposition that catch shares promote conservation, especially of non-target resources, is thinner. Furthermore, in the international context catch shares face special challenges. Catch shares cannot resolve the value differences that underlie the most intractable disagreements about international fisheries management. They are less likely to reduce conflicts over total allowable catch in the international than in the domestic context, because distrust of managers and competitors runs deeper. Finally, catch share strategies require effective enforcement, which is both institutionally and practically difficult to provide for many international fisheries. In general, catch shares are not a promising route to improving international fisheries management, and pursuing them could distract the international community from more important steps toward improving conservation of global ocean resources.

Published: February 2022

The study sought to assess the level of knowledge on the utilization of termites, harvesting methods and characterise local edible termite species. Focus group discussion with key informants was used to collect data that was analysed using SPSS Version 21.0 to generate descriptive statistics. Results indicated different levels of termites’ utilisation where 45% of farmers use alates as food, 35% as feed for chicks and quails, while 20% use the queen to fatten young bulls. Majority of farmers (40%) prefer the use of termites as feed because it is readily available, followed with 20% that use it because of nutritive value,10% relate its use with better taste of poultry products, 5 % associate termite use in enhancing early maturity weight while 5% said it improves growth and strength of bulls. On harvesting, three methods are commonly used with most farmers (45%) using underground trapping method, (35%) use above ground trapping method but 20% use mound excavation. Varied plant materials are used as attractants and the effect is more when combined with dry cow dung. Farmers further characterised species based on time of emergence of alates and habitat’s physical features. Most respondents (45%) associated: big mounds with Macrotermes bellicosus (Mafendete); small mount to Macrotermes subhyalinus (Kitunda); presence of open big tunnels with Coptotermes millitaris (Riamke) while seasonal gallaries and small tunnels was a confirmatory feature of either Pseudocanthotermes militaris (Chiisiisi) and Pseudocanthotermes spiniger (Maburi). The study demonstrates the richness in indigenous knowledge on techniques of termite production and utilization.

Published: February 2022

Structural measurements are indicators of animal performance, productivity and carcass characteristics. This study was conducted with the objectives of assessing structural measurements, developing body weight prediction and structural indices for cows of Arsi breed. The cows were purchased from highland and lowland agro-ecologies of Arsi and East Shoa zones of Oromia regional state, Ethiopia and kept in Adami Tulu Agricultural Research Center (ATARC) for the breed development purpose. Totally 222 cows were included in the structural traits measurement. Thirty four young heifers were also considered in the study. Twenty two structural traits were considered during observational survey. The structural index was calculated from the phenotypically correlated linear measurements. Structural traits were analyzed by T-test of SPSS version twenty four. The observed average values of height at wither, chest depth, heart girth, body length, pelvic width, cannon bone circumferences of the cows were 107, 55.62, 141.06, 117.82, 31.41 and 13.58cm, respectively. Heart girth (0.82), flank girth (0.73), hook circumferences (0.67), chest depth (0.65) and height at rump (0.64) were highly correlated (P< 0.01) to body weight of the cows. Regression analysis indicated that hearth girth had the highest coefficient of determination for body weight of the cows and heifers. Accordingly, the simple linear equations were developed to predict the body weight of cows and heifers. Body weight of Arsi cow (y) = -221.005 + 3.1(heart girth) and Body weight of Arsi heifer (y) = -188.452 + 2.75 (heart girth). Based on this, the measuring chart tape can be developed to estimate the body weight of Arsi cows and heifers at field condition where there is no access to weighing scales.

Published: February 2022

Shortage of freshwater is becoming a growing problem in both dry and semi-dry regions of the world, hence the need to make use of other source of water for agricultural production. The study was conducted to examine the performance of common reed in a constructed wetland for greywater treatment in Akure, Nigeria. Raw greywater was collected from Jadesola Hostel, Federal University of Technology, Akure, and pretreated through a combination of gravel of diameters < 32 mm, 24 mm and 16 mm with fine sand of diameter 0.2 mm arranged accordingly. The filtered water was thereafter released to a plastic constructed wetland (CW) which also consisted of same combination of layers of gravel and sand with common reed planted on it for complete treatment. The raw and treated greywater were analyzed for Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solid (TDS), and heavy metals. It was discovered that CW planted with common reed was effective in the treatment of greywater with reduction in BOD by 91.4%, COD by 91.5% and TDS by 38.7%. CW had appreciable removal effect on heavy metals with reduction in: manganese (Mn) from 0.100 ppm to 0.012 ppm, iron (Fe) from 0.014 ppm to 0.002 ppm, lead (Pb) from 0.05 ppm to 0.001 ppm and zinc (Zn) from 0.154 ppm to 0.148 ppm. Therefore, the use of common reed in constructed wetland for greywater treatment is recommended for farmers involved in irrigation with greywater, especially during dry seasons, and most importantly under the rising global water scarcity due to climate change.

Published: February 2022

OBJECTIVE Ionizing radiation (IR) has a wide area of use and its effects on human health have been discussed since its discovery. This study aimed to show oxidative stress and inflammation due to ionizing radiation exposure based on biomarkers in healthcare workers.

METHOD This study was conducted with 172 people, who were exposed to IR in the work environment and those who did not have exposure to radiation. In this cross-sectional study, a data collection form was used to obtain data from the participants. In addition, 6 ml of blood was taken to measure their tumor necrosis factor (TNF)-alpha, total oxidant status (TOS), interleukin (IL)-10 and total antioxidant status (TAS) levels, and calculate their oxidative stress index (OSI) values.

RESULTS In the ionizing radiation group, 50% of the participants were men, the mean age was 35.91±7.07 years, and the mean duration of employment was 9.80±7.1 years. The TOS, OSI, TNF-α and IL-10 values were higher and TAS was lower in the ionizing radiation group compared to the participants without exposure to ionizing radiation. Gender, smoking, alcohol use, presence of chronic diseases, regular medication use, antioxidant supplement use, and exposure to radiation for medical diagnosis and treatment within the last year did not affect oxidative stress and inflammation in the radiation workers. The cut-off values of the TOS, TAS, OSI, TNF-α and IL-10 biomarkers were also determined.

CONCLUSION Occupational low-dose long-term exposure to ionizing radiation was found to increase oxidative stress and inflammation.
ANALYSIS ON MACHINABILITY OF GFRP COMPOSITE MATERIALS USING TURNING PROCESSES
Authors: D Rajmohan
Published: February 2022

Glass fibre reinforced polymer (GFRP) composite materials replace traditional engineering materials due to their properties. Accordingly, the need for accurate machining of composites has increased enormously. The advantages include high strength to weight ratio, high fracture toughness and excellent corrosion and thermal resistance. Even though the moulding process may produce GFRP parts, they require further machining to facilitate dimensional control for easy assembly and control of surface quality for functional aspects. The material removal mechanism is different from that of machining single-phase materials, such as metals. GFRP are extremely abrasive when machined. Thus, selecting the cutting tool and the cutting parameters is very important in the machining process. The machinability in turning operations of glass fiber reinforced plastics (GFRP) will be investigated by the super-hard cutting tool (PCD and Ceramic Inserts). A plan of experiments will be performed on controlled machining with cutting parameters prefixed in the workpiece.

Empirical Analysis of Exchange Rate Volatility in Emerging African Economies
Authors: Kwarah Abdullahi Murtala
Published: February 2022

Purpose: The study examined the empirical nature of the exchange rates volatilities in a few selected African countries, viz. Botswana, Egypt, Morocco, and South Africa.
Method:  The study used quarterly data (1990q to 2018q) source from the International Monetary Fund (IMF) financial archive through the Easy-Data website. Thus conducted trend analysis which includes descriptive statistics, autoregressive conditional heteroscedasticity based on the Lagrange Multiplier (ARCH-LM) test, the EGARCH model, and the Constant Conditional Correlation GARCH (CCC-GARCH) models. Additionally, test volatility and evaluate the effect of capital flows volatility on exchange rate volatility for all the countries. Further, examine the contagious effect of the exchange rates among the countries. 
Result: The investigations revealed that throughout the study, Botswana experienced the highest rate of exchange rate volatility while Morocco was the least in the sample countries. Further, the series are all platykurtic, i.e. there is a reasonable level of fluctuation in the series throughout the study period. In other words, positive (appreciations) are more likely to occur in Morocco, while depreciation is more likely to occur in other countries. The trend analyses also revealed the presence of relative stability for Morocco's exchange rate, while the exchange rate of the remaining countries varied significantly.
Implications: These fluctuations were acute during the period 2001-2018. In this regard, the study has concluded that the exchange rate volatility of these countries was independently determined. Thus, they can ignore monetary and fiscal policy and pursue internal goals, such as full employment, stable growth, and price stability.

A Self-calibrating Halo-based Galaxy Group Finder: Algorithm and Tests
Authors: Tinker Jeremy L.
Published: February 2022

We describe an extension of the halo-based galaxy group-finding algorithm. We add freedom to the algorithm in order to more accurately determine which galaxies are central and which are satellites, and to provide unbiased estimates of halo masses. We focus on determination of the galaxy-halo relations for star-forming and quiescent galaxies. The added freedom in the group-finding algorithm is self-calibrated using observations of color-dependent galaxy clustering, as well as measurements of the total satellite luminosity in deep imaging data around stacked samples of spectroscopic central galaxies, L
sat. We test this approach on a series of mocks that vary the galaxy-halo connection, including one mock constructed from Universe Machine results. Our self-calibrated algorithm shows marked improvement over previous methods in estimating the color-dependent satellite fraction of galaxies. It reduces the error in

log

M

h

for central galaxies by over a factor of two, to ≲0.2 dex. Through the L
sat data, it can quantify differences in the luminosity-to-halo mass relations for star-forming and quiescent galaxies, even for groups with only one spectroscopic member. Thus, whereas previous algorithms cannot constrain the scatter in L
gal at fixed M

h
, the self-calibration technique can provide a robust lower limit to this scatter.

The relative rarity of giant planets around low-mass stars compared with solar-type stars is a key prediction from the core-accretion planet formation theory. In this paper we report on the discovery of four gas giant planets that transit low-mass late K and early M dwarfs. The planets HATS-74Ab (TOI 737b), HATS-75b (TOI 552b), HATS-76b (TOI 555b), and HATS-77b (TOI 730b) were all discovered from the HATSouth photometric survey and follow-up using TESS and other photometric facilities. We use the new ESPRESSO facility at the VLT to confirm systems and measure their masses. We find that these planets have masses of 1.46 ± 0.14 MJ, 0.491 ± 0.039 MJ, 2.629 ± 0.089 MJ, and

Published: February 2022

The BL Lacertae OJ 287 is a supermassive black hole binary system with complex physics of its irregular flares. During 2016 October–2017 April, a surprising outburst in the X-ray, UV, and optical bands was detected, while no variability was seen in the γ-ray light curve. During the outburst, the X-ray light curves were dominated by the soft X-rays, whose peak in luminosity was ∼1046 erg s−1—more than 10 times higher than the mean level before the outburst—and a “softer-when-brighter” phenomenon was exhibited. These above phenomena have been reported by some previous works. The hardness ratio showed negligible evolution with flare time and soft X-ray luminosity. Critically, the luminosity of the soft X-rays decayed following a power law of t
−5/3, which occurs in most tidal disruption events (TDEs), and a similar trend can be seen in the UV and optical bands during the soft X-ray declining period. Helium and oxygen narrow emission lines are strengthened prominently in the optical spectra of postoutburst epochs, that could be attributed to the surrounding gas caused by TDE. We discuss three possible origins of the event, including the jet’s precession, the aftereffects of the black hole–disk impaction, and the TDE. Our results show that the TDE is the more likely scenario to explain the outburst.

We present new and archival SOFIA FIFI-LS far-IR spectroscopic observations of the [O iii] 52 μm and/or the [N iii] 57 μm lines of 25 local galaxies. Including 31 other galaxies from Herschel-PACS, we discuss a local sample of 47 galaxies, including the H ii galaxies, luminous IR galaxies, low-metallicity dwarfs, and Seyfert nuclei. Analyzing the mid- to far-IR fine-structure lines of this sample, we assess the metallicity and compare it with the optical spectroscopy estimates. Using the IR, we find an O/H–N/O relation similar to that known in the optical. Conversely, we find systematically lower N/O IR abundances when compared to the optical determinations, especially at high values of N/O (

−0.8). We explore various hypotheses to account for this difference: (i) difference in ionization structure traced by optical (O+, N+ regions) versus IR lines (O2+, N2+ regions), (ii) contamination of diffuse ionized gas affecting the optical lines used to compute the N/O abundance, and (iii) dust obscuration affecting the optical-based determinations. However, we have not found any correlation of

with ionization, or electron density, or optical extinction. We speculatively suggest that the accretion of metal-poor gas from the circumgalactic medium could provide an explanation for this difference because the rapid decrease of total abundances during infall is followed by a N/O ratio decrease due to the primary production of young—possibly embedded—massive stars, which are preferentially traced by the IR diagnostics, while optical diagnostics would better trace the secondary production, when both N/O and O/H abundance ratios increase.
Subgalactic Scaling Relations with T

The scaling relationship is a fundamental probe of the evolution of galaxies. Using the integral field spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory survey, we select 1698 spaxels with a significant detection of the auroral emission line [O iii]λ4363 from 52 galaxies to investigate the scaling relationships at the low-metallicity end. We find that our sample’s star formation rate is higher and its metallicity is lower in the scaling relationship than the star-forming sequence after removing the contribution of the Fundamental Metallicity Relation. We also find that the stellar ages of our sample are younger (<1 Gyr) and the stellar metallicities are also lower. Morphological parameters from the Deep Learning catalog indicate that our galaxies are more likely to be mergers. These results suggest that their low-metallicity regions may be related to interaction; the inflow of metal-poor gas may dilute the interstellar medium and form new metal-poor stars in these galaxies during interactions.
Properties of Fast and Slow Bars Classified by Epicyclic Frequency Curves from Photometry of Barred Galaxies

Published: February 2022

We test the idea that bar pattern speeds decrease with time owing to angular momentum exchange with a dark matter halo. If this process actually occurs, then the radii of the corotation resonance and other resonances should generally increase with time. We therefore derive the angular velocity Ω and epicyclic frequency κ as functions of galactocentric radius for 85 barred galaxies using photometric data. Mass maps are constructed by assuming a dynamical mass-to-light ratio and then solving the Poisson equation for the gravitational potential. The locations of Lindblad resonances and the corotation resonance radius are then derived using the standard precession frequency curves in conjunction with bar pattern speeds recently estimated from the Tremaine–Weinberg method as applied to integral field spectroscopy data. Correlations between physical properties of bars and their host galaxies indicate that bar length and the corotation radius depend on the disk circular velocity while bar strength and pattern speed do not. As the bar pattern speed decreases, bar strength, length, and corotation radius increase, but when bars are subclassified into fast, medium, and slow domains, no significant change in bar length is found. Only a hint of an increase in bar strength from fast to slow bars is found. These results suggest that bar length in a galaxy undergoes little evolution, and is determined instead mainly by the size of the host galaxy.

N v and O vi outflows are present in about 60% of the QUEST quasars and span a broad range of properties, both in terms of equivalent widths (from 20 mÅ to 25 Å) and kinematics (outflow velocities from a few×100 km s−1 up to ∼10,000 km s−1). The rate of incidence and equivalent widths of the highly ionized outflows are higher among X-ray weak or absorbed sources. The weighted outflow velocity dispersions are highest among the X-ray weakest sources. No significant trends are found between the weighted outflow velocities and the properties of the quasars and host galaxies, although this may be due to the limited dynamic range of properties of the current sample. These results will be re-examined in an upcoming paper where the sample is expanded to include the QUEST ULIRGs. Finally, a lower limit of ∼0.1% on the ratio of time-averaged kinetic power to bolometric luminosity is estimated in the 2–4 objects with blueshifted P v

The observed correlation between outer giant planets and inner super-Earths is emerging as an important constraint on planet formation theories. In this study, we focus on Kepler-167, which is currently the only system known to contain both inner transiting super-Earths and a confirmed outer transiting gas giant companion beyond 1 au. Using long-term radial velocity monitoring, we measure the mass of the gas giant Kepler-167e (P = 1071 days) to be

⊕ of solids and is significantly enriched in metals relative to its solar-metallicity host star. We use these new constraints to explore the broader question of how systems like Kepler-167 form in the pebble accretion framework for giant planet core formation. We utilize simple disk evolution models to demonstrate that more massive and metal-rich disks, which are the most favorable sites for giant planet formation, can also deliver enough solids to the inner disk to form systems of super-Earths. We use these same models to constrain the nature of Kepler-167's protoplanetary disk and find that it likely contained ≳300 M
⊕ of dust and was ≳40 au in size. These values overlap with the upper end of the observed dust mass and size distributions of Class 0 and I disks and are also consistent with the observed occurrence rate of Jupiter analogs around Sun-like stars.
Excitation and Damping of Slow Magnetosonic Waves in Flaring Hot Coronal Loops: Effects of Compressive Viscosity
Authors: Ofman Leon , Wang Tongjiang
Published: February 2022

Slow magnetosonic waves associated with flares were observed in coronal loops by Solar and Heliospheric Observatory/Solar Ultraviolet Measurements of Emitted Radiation, Solar Dynamics Observatory/Atmospheric Imaging Assembly in various EUV bandpasses, and other instruments. The excitation and damping of slow magnetosonic waves provides information on the magnetic, temperature, and density structure of the loops. Recently, it was found using 1.5D models that the thermal conduction is suppressed and compressive viscosity is enhanced in hot (T > 6 MK) flaring coronal loops. We model the excitation and dissipation of slow magnetosonic waves in hot coronal loops with realistic magnetic geometry, enhanced density, and temperature (compared to background corona) guided by EUV observations using a 3D magnetohydrodynamic (MHD) visco-resistive model. The effects of the compressive viscosity tensor component along the magnetic field are included with classical and enhanced viscosity coefficient values for the first time in a 3D MHD coronal loop model. The waves are excited by a velocity pulse at the footpoint of the loop at the coronal lower boundary. The modeling results demonstrate the excitation of the slow magnetosonic waves and nonlinear coupling to other wave modes, such as the kink and fast magnetosonic. We find significant leakage of the waves from the hot coronal loops with a small effect of viscous dissipation in cooler (6 MK) loops, and more significant effects of viscous dissipation in hotter (10.5 MK) coronal loops. Our results demonstrate that nonlinear 3D MHD models are required to fully account for the various wave couplings, damping, standing wave formation, and viscous dissipation in hot flaring coronal loops. Our viscous 3D MHD code provides a new tool for improved coronal seismology.

The Multi-slit Solar Explorer (MUSE) is a proposed mission composed of a multislit extreme ultraviolet (EUV) spectrograph (in three spectral bands around 171 Å, 284 Å, and 108 Å) and an EUV context imager (in two passbands around 195 Å and 304 Å). MUSE will provide unprecedented spectral and imaging diagnostics of the solar corona at high spatial (≤0.″5) and temporal resolution (down to ∼0.5 s for sit-and-stare observations), thanks to its innovative multislit design. By obtaining spectra in four bright EUV lines (Fe ix 171 Å, Fe xv 284 Å, Fe xix–Fe xxi 108 Å) covering a wide range of transition regions and coronal temperatures along 37 slits simultaneously, MUSE will, for the first time, “freeze” (at a cadence as short as 10 s) with a spectroscopic raster the evolution of the dynamic coronal plasma over a wide range of scales: from the spatial scales on which energy is released (≤0.″5) to the large-scale (∼170″ × 170″) atmospheric response. We use numerical modeling to showcase how MUSE will constrain the properties of the solar atmosphere on spatiotemporal scales (≤0.″5, ≤20 s) and the large field of view on which state-of-the-art models of the physical processes that drive coronal heating, flares, and coronal mass ejections (CMEs) make distinguishing and testable predictions. We describe the synergy between MUSE, the single-slit, high-resolution Solar-C EUVST spectrograph, and ground-based observatories (DKIST and others), and the critical role MUSE plays because of the multiscale nature of the physical processes involved. In this first paper, we focus on coronal heating mechanisms. An accompanying paper focuses on flares and CMEs.

La dématérialisation des démarches administratives génère une mutation du travail social et renvoie aux usagers la responsabilité de gestion de leurs dossiers. Les difficultés rencontrées par les publics face à l’e-administration impactent l’activité des travailleurs sociaux, modifient leurs pratiques professionnelles et la nature de la relation d’aide, marquée chez les publics par des attentes d’immédiateté, des stratégies d’évitement et des menaces de sanction. Les travailleurs sociaux investissent variablement leurs marges de manœuvre dans l’accompagnement à l’e-administration en fonction de leurs propres usages du numérique, de leurs compétences et appétences, des représentations qu’ils ont de leurs missions mais aussi de leurs conditions de travail, de l’organisation des accueils, des directives et des moyens à disposition.
Are fructophilic lactic acid bacteria (FLAB) beneficial to humans?
Authors: Dicks L.M.T. , Endo A.
Published: February 2022

Fructophilic lactic acid bacteria (FLAB) are heterofermentative and related to the genera Fructilactobacillus, Convivina, Leuconostoc, Oenococcus and Weissella. Although they generally prefer fructose above glucose, obligate heterofermentative species will ferment glucose in the presence of external electron acceptors such as pyruvate and fructose. Little is known about the presence of FLAB in the human gut, let alone probiotic properties. In this review we discuss the possible role FLAB may have in the human gastro-intestinal tract (GIT) and highlight the advantages and disadvantages these bacteria may have in individuals with a diet high in fructose.
