description: The coenzyme A (CoA) biosynthesis pathway has attracted attention as a potential target for much-needed novel antimicrobial drugs, including for the treatment of tuberculosis (TB), the lethal disease caused by Mycobacterium tuberculosis (Mtb). Seeking to identify inhibitors of Mtb phosphopantetheine adenylyltransferase (MtbPPAT), the enzyme that catalyses the penultimate step in CoA biosynthesis, we performed a fragment screen. In doing so, we discovered three series of fragments that occupy distinct regions of the MtbPPAT active site, presenting a unique opportunity for fragment linking. Here we show how, guided by X-ray crystal structures, we could link weakly-binding fragments to produce an active site binder with a KD <20 μM and on-target anti-Mtb activity, as demonstrated using CRISPR interference. This study represents a big step toward validating MtbPPAT as a potential drug target and designing a MtbPPAT-targeting anti-TB drug.

description: Asset-accumulation interventions are promising tools for promoting better educational outcomes. However, little is known about the educational effects of youth-owned assets, particularly in resource-limited countries. The Ghana YouthSave Experiment established a rigorous foundation for exploring youth responses when offered opportunities to save for their education. This study uses data from 2000 junior high YouthSave participants, who were randomly assigned to one of two treatments (in-school or local bank access) or the control group. Treatment effects on school attendance and academic performance are examined using difference-in-difference estimation with bootstrapped standard errors. Treatment effects were significant for attendance but not performance. Findings suggest longer posttreatment follow-up is needed for effects to manifest. This study demonstrates the potential of asset-accumulation programs to contribute to improved behavioral outcomes, and offers insights for the integration of financial capability programs in youth development policies.

description: Introduction: Research on the influence of academic self-efficacy and educational aspirations on academic performance is underdeveloped in resource-limited countries. This study replicates and expands on earlier research that investigated a complex network of relationships between academic self-efficacy, educational aspirations, and academic performance. Methods: Data from 4282 adolescents in Ghana and path analysis were used to test the causal pathways, and path invariance analysis was used to assess the moderation role of gender. Instrumental variable techniques were used to validate the path models. Results: Increase in academic self-efficacy indirectly accounts for improvement in academic performance through the mediational role of educational aspirations. The effects of self-efficacy on educational aspirations, and educational aspirations were stronger for boys than for girls. Conclusions: These findings suggest that in resource-limited countries where the financial burden of schooling tends to be a demotivating factor, interventions that target adolescents' academic self-efficacy may be an effective means to boost educational aspirations and academic performance. Interventions should be tailored to meet the needs of all students so that all children can think of school as an important part of their lives and aspire to achieve, now and in the future.

description: Background: The present study aims to (1) identify classes of psychosocial syndemics among adolescents in the U.S. based on psychological factors, such as depression and suicidal ideation, and social factors, such as binge drinking, alcohol use, and drug use; (2) identify correlates of psychosocial syndemics; and (3) examine the independent associations between psychosocial syndemic factors and sexual risk practices. Method: We used latent class analysis and a sample of 14,762 U.S. high school students who participated in the 2017 Youth Risk Behavior Surveillance System to examine youth population profiles based on shared characteristics of syndemics. Adjusting for sociodemographic factors, we conducted logistic regression to explore the connections between psychosocial syndemic factors and three sexual risk practices, namely, early initiation of sexual intercourse, condom use, and sex with multiple partners. Results: The study results indicate that three classes of risk exist among the sample: substance misuse (class 1, n = 3872, 26.2%), normative (class 2, n = 8791, 59.6%), and mental health problems (class 3, n = 2099, 14.2%). Class membership of psychosocial syndemics was significantly different by gender, age group, and race. The odds of initiating sexual intercourse before age 13 were positively associated with participants belonging in the substance misuse class and the mental health problem class. The odds of using condoms during the last sexual intercourse for currently sexually active adolescents were lower for participants classified in the substance misuse class. The likelihood of reporting having sex with four or more partners in a lifetime was higher among participants belonging to the substance misuse class. Conclusion: The study advances our understanding of the heterogeneity of class membership associated with psychosocial syndemic risk factors among adolescents and extends our understanding of syndemics in the area of adolescent health. Thus, practitioners and policymakers can design multicomponent and multilevel school-based HIV/STI prevention programs that meet the needs of adolescents.
High Energy Polarization of Blazars : Detection Prospects

description: Emission from blazar jets in the ultraviolet, optical, and infrared is polarized. If these low-energy photons were inverse-Compton scattered, the upscattered high-energy photons retain a fraction of the polarization. Current and future X-ray and gamma-ray polarimeters such as INTEGRAL-SPI, PoGOLITE, X-Calibur, Gamma-Ray Burst Polarimeter, GEMS-like missions, ASTRO-H, and POLARIX have the potential to discover polarized X-rays and gamma-rays from blazar jets for the first time. Detection of such polarization will open a qualitatively new window into high-energy blazar emission; actual measurements of polarization degree and angle will quantitatively test theories of jet emission mechanisms. We examine the detection prospects of blazars by these polarimetry missions using examples of 3C 279, PKS 1510-089, and 3C 454.3, bright sources with relatively high degrees of low-energy polarization. We conclude that while balloon polarimeters will be challenged to detect blazars within reasonable observational times (with X-Calibur offering the most promising prospects), space-based missions should detect the brightest blazars for polarization fractions down to a few percent. Typical flaring activity of blazars could boost the overall number of polarimetric detections by nearly a factor of five to six purely accounting for flux increase of the brightest of the comprehensive, all-sky, Fermi-LAT blazar distribution. The instantaneous increase in the number of detections is approximately a factor of two, assuming a duty cycle of 20% for every source. The detectability of particular blazars may be reduced if variations in the flux and polarization fraction are anticorrelated. Simultaneous use of variability and polarization trends could guide the selection of blazars for high-energy polarimetric observations.

description: After reviewing the construction of metric from premetric electrodynamics with empirical improvement of accuracy in the skewonless case, we explore the role of skewons in the construction of spacetime metric in the full premetric electrodynamics. For metric principal part plus skewon part, we have shown that the Type I skewon part is constrained to < a few x 10^(-35) in the weak field/weak EEP violation limit. Type II skewon part is not constrained in the first order. However, in the second order it induces birefringence; the nonbirefringence observations constrain the Type II skewon part to 10^(-19). Nevertheless, an additional nonmetric induced second-order contribution to the principal part constitutive tensor compensates the Type II skewon birefringence and makes it nonbirefringent. This second-order contribution is just the extra piece to the core-metric principal constitutive tensor induced by the antisymmetric tensor. From the Tamm-Rubilar tensor density and the dispersion relation for the spacetime medium with the asymmetric-metric-induced constitutive tensor, we know that it is nonbirefringent. The antisymmetric metric induced constitutive tensor has a pseudoscalar part in the decomposition. The variation of his part is constrained by observation on cosmic polarization rotation to < 0.03, and gives one constraint on the 6-degree-of-freedom antisymmetric metric. Further studies of these 6 degrees of freedom experimental and theoretically are desired.

Processes affecting macrofaunal community structure in sandy sediments on the New Jersey inner continental shelf with a focus on the dominant polychaete, polygordius jouinae
Creators: name: Ramey, Patricia Ann
Publisher: name: No Publisher Supplied
Year: 2008

description: Continental shelves contain a rich array of habitats that appear significant for macrofauna and play an essential role in managing living resources. Yet, many habitats have not been adequately defined or quantified, temporally or spatially. Macrofaunal communities were examined at spatial and temporal scales within the context of known distributions of topographic habitats and associated sediment properties on the shelf off New Jersey, USA (39° 28' N, 74° 15' W). Focusing on a dominant polychaete, species identification and natural history information, together with manipulative experiments on behavior and habitat selection, provided a multi-pronged approach to research. Nested sampling designs were employed. Samples taken at large-spatial scales (m-km) showed that community differences were most pronounced among sampling dates, however, on any single date differences were related to crests and troughs in the rippled sandbeds. At small-scales (cm-m) community patterns and sediment properties corresponded with crests, flanks, and troughs. Concentrations of organic matter associated with finer sediments in troughs were ~1.2 times higher than in crests and flanks. Density of P. jouinae Ramey, Fiege and Leander, 2006, was higher in troughs than in crests. This species appears to thrive in sandy sediments from Massachusetts to southern New Jersey. The reproductive period occurred from May-August. Individuals that spawn, live for one year. Recruitment begins no later than July. The smallest individual was 2.01 mm long providing an estimate of size at initial recruitment. It was hypothesized that heterogeneity in organic matter generated by rippled beds may influence small-scale distribution patterns of P. jouinae. In a racetrack flume under realistic flow, almost all P. jouinae moved through the sediment to patches containing higher amounts of organic matter in 48-h. Subsequent experiments showed that locating organic patches was not the consequence of a directed search. Rate of movement indicated that P. jouniae could potentially travel the wavelength of a typical ripple (14-30 cm) in 35-75 min. Thus subsurface movement is a plausible mechanism accounting for the similar small-scale spatial distributions of P. jouinae and food resources. This research reveals the fundamental influence of topographic differences in habitats on a member of the benthic macrofaunal community.

description: Purpose: The purpose of this paper is to examine the spatial patterns of gender inequality in junior high school enrollment and the educational resource investments associated with the spatial trends. Design/methodology/approach: The paper uses data on 170 districts in Ghana and hot spot analysis based on the Getis-Ord Gi statistic, linear regression, and geographically weighted regression to assess spatial variability in gender parity in junior high school enrollment and its association with resource allocation. Findings: The results reveal rural-urban and north-south variability in gender parity. Results show that educational resources contribute to gender parity. At the national level, educational expenditure, and the number of classrooms, teachers, and available writing places have the strongest positive associations with girls’ enrollment. These relationships are spatially moderated, such that predominantly rural and Northern districts experience the most substantial benefits of educational investments. Practical implications: The findings show that strategic allocation of infrastructure, financial, and human resources through local governments holds promise for a more impactful and sustainable educational development of all children, regardless of gender. Besides seeking solutions that address the lack of resources at the national level, there is a need for locally tailored efforts to remove the barriers to equitable distribution of educational resources across gender and socioeconomic groups. Originality/value: This paper’s use of advanced spatial analysis techniques allows for in-depth examination of gender parity and investments in educational resources, and highlights the spatial nuances in how such investments predict gender disparities in junior high school enrollment. The findings speak to the need for targeted and localized efforts to address gender and geographical disparities in educational opportunities.

description: Nongovernmental organizations (NGOs) play important roles in social development in the Global South. However, little evidence exists concerning NGOs’ capacity-building needs. We sought to understand organizational and network factors that explain capacity-building needs. Using an online survey of 282 NGOs in Ghana, Kenya, and Nigeria, we found high levels of capacity-building need, particularly concerning resource development. Using multivariate analyses, we found greater staff size predicted less overall capacity-building need based on a 15-item index (α =.88). Examining individual capacities, receiving at least half of funding from international sources and prior capacity-building assistance were consistent predictors of lower odds of capacity-building need.

description: (Abridged) Gaia aims to make a 3-dimensional map of 1,000 million stars in our Milky Way to unravel its kinematical, dynamical, and chemical structure and evolution. Gaia's on-board detection software discriminates stars from spurious objects like cosmic rays and Solar protons. For this, parametrised point-spread-function-shape criteria are used. This study aims to provide an optimum set of parameters for these filters. We developed an emulation of the on-board detection software, which has 20 free, so-called rejection parameters which govern the boundaries between stars on the one hand and sharp or extended events on the other hand. We evaluate the detection and rejection performance of the algorithm using catalogues of simulated single stars, double stars, cosmic rays, Solar protons, unresolved galaxies, and asteroids. We optimised the rejection parameters, improving - with respect to the functional baseline - the detection performance of single and double stars, while, at the same time, improving the rejection performance of cosmic rays and of Solar protons. We find that the minimum separation to resolve a close, equal-brightness double star is 0.23 arcsec in the along-scan and 0.70 arcsec in the across-scan direction, independent of the brightness of the primary. We find that, whereas the optimised rejection parameters have no significant impact on the detectability of de Vaucouleurs profiles, they do significantly improve the detection of exponential-disk profiles. We also find that the optimised rejection parameters provide detection gains for asteroids fainter than 20 mag and for fast-moving near-Earth objects fainter than 18 mag, albeit this gain comes at the expense of a modest detection-probability loss for bright, fast-moving near-Earth objects. The major side effect of the optimised parameters is that spurious ghosts in the wings of bright stars essentially pass unfiltered.

description: With the recent LHCb data on $η_c$ production and based on heavy quark spin symmetry, we obtain the long-distance matrix elements for both $η_c$ and $J/ψ$ productions, among which, the color-singlet one for $η_c$ is obtained directly by the fit of experiment for the first time. Using our long-distance matrix elements, we can provide good description of the $η_c$ and $J/ψ$ hadroproduction measurements. Our predictions on $J/ψ$ polarization are in good agreement with the LHCb data and pass through the two sets of CDF measurements in medium $p_t$ region. Considering all the possible uncertainties carefully, we obtained quite narrow bands of the $J/ψ$ polarization curves.

description: The effects of soft errors in processor cores have been widely studied. However, little has been published about soft errors in uncore components, such as memory subsystem and I/O controllers, of a System-on-a-Chip (SoC). In this work, we study how soft errors in uncore components affect system-level behaviors. We have created a new mixed-mode simulation platform that combines simulators at two different levels of abstraction, and achieves 20,000x speedup over RTL-only simulation. Using this platform, we present the first study of the system-level impact of soft errors inside various uncore components of a large-scale, multi-core SoC using the industrial-grade, open-source OpenSPARC T2 SoC design. Our results show that soft errors in uncore components can significantly impact system-level reliability. We also demonstrate that uncore soft errors can create major challenges for traditional system-level checkpoint recovery techniques. To overcome such recovery challenges, we present a new replay recovery technique for uncore components belonging to the memory subsystem. For the L2 cache controller and the DRAM controller components of OpenSPARC T2, our new technique reduces the probability that an application run fails to produce correct results due to soft errors by more than 100x with 3.32% and 6.09% chip-level area and power impact, respectively.

description: Schools are the primary settings where both education and health services are delivered to youth in developing countries. A similar approach can be used for financial inclusion. Financial inclusion, in turn, can lead to positive youth development outcomes in education and health. But a critical first step is financial access. This study examines how schools can serve as the setting for financial education and financial services, increasing youth economic participation. Research in four developing countries finds an increase in youth savings account uptake when financial institutions provide opportunities at schools for youth to receive financial education, open savings accounts, and make deposits. Findings are that school banking can overcome some of the regulatory, geographic, and information barriers that limit youth access to safe and affordable savings services. Marginalized youth, including those who are low-income and females, participate as much as other youth. We conclude that schools can play an important role in increasing youth economic participation, a positive step toward economic strengthening and overall well-being. As a possible implication, school-based health programming might consider integrating school banking features, such as opening savings accounts, into future program design and implementation.

description: Research has shown that several factors influence student engagement, but little is known about the predictive role of family economic hardships on student engagement, particularly in the sub-Saharan African context. This study used data from junior high school students in Ghana to examine the association between perceived family economic hardship and students' classroom engagement, and the intervening role of future intentions. The structural equation modeling results indicate that perceived economic hardship is associated with behavioral engagement in school in two ways. The first is the direct positive link from perceived economic hardship to engagement (i.e., the motivational pathway). The second is a more nuanced channel whereby perceived economic difficulties are negatively associated with students' participation in academic work, but only through the inconsistent mediating (suppression) role of students' future intentions (i.e., the demoralizing pathway). The nuanced psychological and behavioral outcomes suggest the need for programs that cultivate educational resilience among young people.
Assessing multiple indicators of nutrient limitation in marine phytoplankton on the Louisiana continental shelf
Creators: name: Sylvan, Jason B.
Publisher: name: No Publisher Supplied
Year: 2008

description: Eutrophication on the Louisiana continental shelf is driven by excess nitrogen (N) and phosphorus (P) delivered by the Mississippi River. While the eutrophication is driven primarily by excess nitrogen, scattered data going back to the early 1990's suggests that the ecosystem on the Louisiana shelf may be seasonally P-limited in the spring and early summer during high runoff periods, primarily in areas of intermediate salinity. These intermediate salinity zones are also the areas where chlorophyll biomass and primary productivity are often maximal. This production likely drives the annual bottom water hypoxia in the region, known in the popular press as the "dead zone." Three very different methods were used to address the question of nutrient limitation on the Louisiana shelf. In July 2002, a Fast Repetition Rate fluorometer (FRRf) was used in conjunction with nutrient addition bioassays and mapping of surface water parameters to examine the response of the phytoplankton community to eutrophication. In incubations, chlorophyll a biomass responded to phosphorus additions, but not those of N alone and FRRf parameters indicated a positive response to P additions in the way of higher efficiency in photosystem II. The mapping data was more heterogeneous in nature, but overall patterns indicated that P limited phytoplankton biomass. Three cruises in March, May and July 2004 were conducted in order to investigate seasonal patterns of dissolved inorganic, dissolved organic, and particulate nutrients on the Louisiana shelf. The combination of low P concentrations, high inorganic and total N:P ratios and high alkaline phosphatase activities indicated P limitation of phytoplankton biomass on the Louisiana shelf during the spring and early summer of 2004. A study of pstS, a gene induced under P-stress, revealed that its distribution in oceanic waters is related to location of the sample. The pstS gene in Synechococcus spp. taken from various sites around the world clustered on a phylogenetic tree closest to other sequences taken nearby. The combination of FRRf, nutrient data, enzyme assays and molecular markers of P-limitation strongly confirm seasonal P-limitation on the Louisiana continental shelf in the spring and early summer, driven by extreme N loads during these seasons.

description: Non-governmental organizations (NGOs) in sub-Saharan Africa (SSA) experience financial challenges that hinder efforts to promote social change and development. Revenue diversification is one adaptive response to these challenges, yet there is a lack of evidence concerning the relationship between revenue diversification and financial vulnerability among NGOs in SSA. Using data from an online survey of NGOs (N = 170), we hypothesized that a greater number of revenue sources is associated with lower probability of financial vulnerability, while a greater level of dependence on international funding is associated with higher probability of financial vulnerability. Results from probit regression models controlling for organizational characteristics indicated partial support for hypotheses. Having four or more types of revenue was associated with 87% lower probability of financial vulnerability compared to having one type of revenue (p < 0.001). Also, NGOs with up to half of their budgets covered by international sources had 17% lower probability of financial vulnerability compared to NGOs with no international funding (p < 0.05). Implications for future research to further explore these relationships are discussed.
An evaluation of clam amiantis umbonella (bivalve) as a bio-indicator of heavy metal pollution in Kuwait marine coastal waters

description: To evaluate the clam Amiantis umbonella as a bio-indicator of metal contamination, the concentrations of a number of metals (Hg, Cd, Pb, Cu, Ni, Mn, Cr, V, Zn, and Fe) were determined in clam's soft tissues, in different organs, water, and sediment in Kuwait Bay of the Arabian Gulf. The primary objective of this study was to evaluate the relationship of all metals concentrations in soft tissue and various organs of clam, water and sediment and to compare them with a reference site, and with results obtained from other geographical areas of the world. Metal concentrations and metal burdens of Pb, Hg, Cu, and Cd in the soft tissues of clam were also compared as a function of clam size. Hg, Cd, Cu, Ni, Cr, V and Pb were significantly higher in water and sediment near point sources compared to reference sites. The concentration of all metals, except Zn were significantly higher in kidneys, gonads, mantles, gills, livers and hearts of contaminated site clams, compared to the reference site clams. The highest inter-location variability was in kidneys, compared to all other organs. The concentration of Cu, Hg, Ni and Fe in contaminated site clams was significantly higher in the gonads (15.0 ppm, 2.32 ppm, 4.3 ppm, 4.6 ppm wet weight respectively) than in kidneys, mantles and livers. The highest Cr concentration (12.5 ppm) was in the mantles. The liver was found to be the main depository of Cu (16.7 ppm) in contaminated site clams. Among the metals, Cd body burden and concentration was positively correlated to clam's wet weight/length. However, the concentrations of Pb, Hg and Cu were not correlated with clam length or weight, indicating it may be biologically regulated.The concentrations of Ni, Cu, Cd, Pb, Mn, V and Cr in sediment were highly correlated with those in water. The levels of metals in clams from this study are generally within the range of mean values reported in the literature for other areas of the world. Only elevated levels of Hg (6.2 ppm), Pb (2.0 ppm) and Cd (4.8 ppm) from Kuwait exceeded the levels set by FAO, WHO and FDA for human consumption.

description: This paper explores experimental impacts of in-school banking and marketing outreach on the savings performance of youth in Ghana. Findings suggest that youth in treatment schools performed better than those in control schools in terms of account opening, depositing and savings. Between the two treatment conditions, in-school banking was more effective than marketing outreach in promoting savings. These findings demonstrate that a meaningful proportion of low-income youth, in a resource-limited country, can be connected to formal financial services and save if access and opportunities are available. The results support the offering of financial services at schools as a strategy to expand youth financial inclusion.
A tale of two prisons: a study in the relationship between communities and prisons in two rural towns

Year: 2008

description: This dissertation is about the nuts and bolts of local politics, something not studied enough in our discipline. Studies of politics and prisons at the higher levels of government abound, but very little has been done to understand these entities on the micro level. To just discuss the prison building boom writ large is to forget that these prisons are actually built in towns. Although some large cities may be able to absorb a large facility with very little impact on the community as a whole, this is not the case in a small rural community, where the prison population may equal the population of free citizens. This is a study of two of these new prison towns: Beeville, Texas and Florence Colorado. Both are small rural communities who began the lobbying process in the late 1980's. Beeville had fallen on hard economic times with the decline of the Texas oil boom and Florence, though never an economic hot spot, lost a significant number of jobs and residents with the decline of the mining industry. Both communities worked hard to land a facility, Beeville from the Texas Department of Corrections (now Texas Department of Criminal Justice or TDCJ) and Florence from the Federal Bureau of Prisons (BOP) and both have since become the site of multiple facilities. They are both examples of the new rural prison towns that have cropped up all over the country over the past 25 years. This dissertation is a study of the institutional relationships that develop after the prison opens.

description: FastCam is an instrument designed to obtain high spatial resolution images in the optical wavelength range from ground-based telescopes by using the Lucky Imaging technique. This technique is based on the idea of registering the instants of atmospheric stability, typically lasting just some milliseconds, using very short exposures. The instrument consists of a very low noise and very fast readout speed EMCCD camera capable of reaching the diffraction limit of medium-sized telescopes from 380 to 1000 nm. At the beginning of 2019, a new camera was commissioned. Now the instrument makes use of an Andor iXon DU-888U3-CSO#BV back-illuminated system containing a 1024x1024 pixel frame transfer CCD sensor from E2V Technologies. The pixel size is 13 microns and the camera allows up to 30 exposures per second. A new update of the camera acquisition software is currently being worked on. A complete characterisation of the detector is also being carried out in order to better understand and exploit all the performances of the instrument, applying particular configurations for each scientific case. A standard reduction of the data is also being implemented in order to offer it to all users of the instrument. The first FastCam was an instrument jointly developed by the Spanish Instituto de Astrofísica de Canarias (IAC) and the Universidad Politécnica de Cartagena which started in 2006. Since then, the IAC assumed the instrument and tested it on several telescopes of the OOCC, among them the Nordic Telescope (NOT) where images were obtained in the optical domain diffraction-limited with high contrast, reaching a resolution of 0.1"/px.
 Currently FastCam is a common-user instrument at the Cassegrain focus of the 1.52-meter Carlos Sánchez Telescope (TCS, Teide Observatory) where observations are being made to calibrate the detector with sky tests. The idea is that in the near future it will be installed in the NOT to finish the commissioning process of the new camera and the whole acquisition system so that this instrument can be used by the international community.

description: The literature is unequivocal about the importance of improving academic engagement in addressing challenges such as school drop out or increasing student motivation. What is less certain, particularly in the literature from developing countries, is how social support systems (parents, teachers, and classmates) influence students’ emotional and behavioral engagement. Drawing from the ecological perspective, this study analyzes data from Ghana using structural equation modeling to examine mediated and unmediated pathways through which parent, teacher, and classmate support affect students’ emotional and behavioral engagement. Findings suggest classmate support has the strongest association with student engagement, followed by parental support. Teacher support is neither a mediator nor a direct predictor of student engagement. These findings have implications for teacher training and professional development, especially training on how to actively involve parents in motivating their children to be engaged scholars.

description: The purpose of this multiple case study was to investigate the language practices of men and women in VXI. These language practices range from the manner of speaking, listening and interacting. Using purposive sampling, the participants of this inquiry were two call center agents of VXI. After employing a thematic and cross-case analysis, the following themes emerged: create connections, straightforward, talkative, eye contact, apologize and explain. These themes presented different language practices of VXI call center agents according to gender. The study was able to provide implications, insights and topics which will require future explorations.

description: Studies have examined a broad range of factors for how students use their time, but few attempts have been made to explore the nuanced link between different types of asset ownership and students' use of study time, particularly in resource-limited countries. This study uses data from junior high school students in Ghana to examine how students spend their time after school hours, the predictive influence of different types of household assets, and the extent to which these trends and relationships vary by gender. Polynomial quantile regression models were fitted across three quantiles (24th, 53rd, and 76th percentiles) to align with one hour, one and half hours, and two hours of study time. Results show that the average student spends well above the recommended 90 minutes on their schoolwork during afterschool hours, regardless of gender. Multivariate results indicate that owning limited assets tends to have a negative relationship with use of study time, but higher levels tend to be positively related to use of study time. Also, the predictive influence of asset ownership varies by asset type, and higher levels of asset ownership favor girls more than boys. Given this study's realtively small sample size, caution must be exercised in generalizing the study findings to the general population of junior high school students in Ghana. In light of the study's limitations, the finding of varying asset effect may have practical implications for asset development programs designed to enhance the well-being of low-income families.
Segregation of a Keplerian disc and sub-Keplerian halo from a Transonic flow around a Black Hole by Viscosity and Cooling processes

description: A black hole accretion is necessarily transonic. In presence of sufficiently high viscosity and cooling effects, a low-angular momentum transonic flow can become a standard Keplerian disc except close to the where hole where it must pass through the inner sonic point. However, if the viscosity is not high everywhere and cooling is not efficient everywhere, the flow cannot completely become a Keplerian disc. In this paper, we show results of rigorous numerical simulations of a transonic flow having vertically varying viscosity parameter (being highest on the equatorial plane) and optical depth dependent cooling processes to show that the flow indeed segregates into two distinct components as it approaches a black hole. The component on the equatorial plane has properties of a standard Keplerian disc, though the flow is not truncated at the inner- most stable circular orbit. This component extends till the horizon as a sub-Keplerian flow. This standard disc is found to be surrounded by a hot, low angular momentum component forming a centrifugal barrier dominated oscillating shock wave, consistent with the Chakrabarti-Titarchuk two component advective flow configuration.

description: The stability of networks is greatly influenced by their degree distributions and in particular by their broadness. Networks with broader degree distributions are usually more robust to random failures but less robust to localized attacks. To better understand the effect of the broadness of the degree distribution we study here two models where the broadness is controlled and compare their robustness against localized attacks (LA) and random attacks (RA). We study analytically and by numerical simulations the cases where the degrees in the networks follow a Bi-Poisson distribution $P(k)=αe^{-λ_1}\frac{λ_1^k}{k!}+(1-α) e^{-λ_2}\frac{λ_2^k}{k!},α\in[0,1]$, and a Gaussian distribution $P(k)=A \cdot exp{(-\frac{(k-μ)^2}{2σ^2})}$ with a normalization constant $A$ where $k\geq 0$. In the Bi-Poisson distribution the broadness is controlled by the values of $α$, $λ_1$ and $λ_2$, while in the Gaussian distribution it is controlled by the standard deviation, $σ$. We find that only for $α=0$ or $α=1$, namely degrees obeying a pure Poisson distribution, LA and RA are the same but for all other cases networks are more vulnerable under LA compared to RA. For Gaussian distribution, with an average degree $μ$ fixed, we find that when $σ^2$ is smaller than $μ$ the network is more vulnerable against random attack. However, when $σ^2$ is larger than $μ$ the network becomes more vulnerable against localized attack. Similar qualitative results are also shown for interdependent networks.
