The informal sector in Kingston, Jamaica: A description of literacy, educational attainment, and occupational skills
Creators: name: Jalloul, Janet Terrell
Publisher: name: American University
Year: 2023

description: The purpose of this study was to describe the degree of functional literacy, educational attainment levels, and the variety of occupational skills of a sample population working in the informal sector in Kingston, Jamaica. The study provided an educational/skills profile of the sample population and an examination of related policy issues. The methodology used was non-intrusive and designed specifically for persons engaged in informal sector economic activities. An interview guide, functional literacy tests, and observations of occupational skills were used to gather quantitative and qualitative information from two hundred participants in four informal sector activities: street foods, handicrafts, fruits and vegetables, and small-scale services. Twenty-five men and twenty-five women were interviewed in each of the four economic groups. The researcher contacted participants while they were working at their business sites. A survey instrument developed by the researcher was administered through personal interviews. To test functional literacy participants responded to information or questions written on a card about their particular economic activity. Each participant in the study was contacted a minimum of two times and a maximum of three times. The findings showed that ninety percent of those in the sample were functionally literate, and all but 35 had completed at least through the primary school level. The majority of those in the sample had three or more occupational skills. Forty-five percent of the sample kept written records or ledgers of business activities, and had formulated plans for expansion of their businesses. Data were also collected through ten interviews with government officicals, Agency for International Development staff, and voluntary organization staff, focusing on policies toward and attitudes about the informal sector population in Kingston. Results of the research suggest that those in the Kingston informal sector are not expecting to enter the formal economy, nor are they seeking additional training. The most often expressed need was for small-scale loans to expand stock and enlarge the businesses; none of those in the study was able to meet that need. New directions in government policies to promote the development of the informal sector have been suggested by the researcher.

description: Background: Despite the technological advancements made in pediatric liver transplant, concerns remain about the equality of patient care during the peri-operative period. Analyses have consistently shown discrepancies in mortality, graft failure, and waitlist time across race, ethnicity and socioeconomic status. National analyses, however, are lacking as most reported data comes from single-hospital studies without adequate power to account for possible confounding variables. The aim of this study was to evaluate the impact of race, ethnicity, and SES on transplant outcomes and resource utilization on a national level, using a linked administrative database. Methods: Utilizing a novel linkage of the Scientific Registry of Transplant Recipients and the Pediatric Health Information System administrative databases, we performed a multicenter, retrospective analysis of 3609children age  18 years, who received a LT in the US between 2003 and 2017. Proportional hazards models were used to assess effect of race and SES on patient and graft survival. Resource utilization was measured by length of stay (LOS), intensive care unit (ICU) LOS, length of mechanical ventilation (MV) and vasopressors, and total charges.Results: White recipients had graft survival advantages compared to black patients (p= .007). This difference persisted after adjusting for resource utilization and recipient and donor characteristics (hazard ratio [HR]1.47; 95% CI 1.082.00). There was no significant difference in overall survival between races. Resource utilization did not differ significantly between black and white races. Privately insured recipients had advantages in both graft (p = .003) and patient survival(p = .014)compared to publicly insured patients. This difference remained when 3adjusted with the multivariate model(graft failure: HR = 1.28, 95% CI 1.011.62; survival: HR 1.38 (95% CI, 1.071.77). Publicly insured patients also had increased resource utilization compared to privately insured patients: LOS (16vs 15days, p= .001), ICU LOS (4 vs. 3 days, p=.001),TPN time(2vs. 1days, p = .004) ), and total charge ($145871vs. $129872, p< .001).Conclusions: In pediatric LT recipients, publicly insured patients showed increased risk of graft failure, death, and resource utilization as compared to privately insured patients; these differences were not as consistent across patient race, but still showed trends towards worse survival and graft failure with minority status.

description: A radio interferometer uses time delays to maximize its response to radiation coming from a particular direction. These time delays compensate for differences in the time of arrival of the wavefront at the different elements of the interferometer, and for delays in the instrument's signal chain. If the radio interferometer is operated as a phased array (tied array), the time delays cannot be accounted for after an observation, so they must be determined in advance. Our aim is to characterize the time delays between the stations in the core of the LOw Frequency ARray (LOFAR). We used radio holography to determine the time delays for the core stations of LOFAR (innermost 3.5 km). Using the multibeaming capability of LOFAR we map the voltage beam faster than with a raster scan, while simultaneously calibrating the observed beam continuously. For short radio holographic observations (60 s and 600 s) of 3C196, 3C147, and 3C48 we are able to derive time delays with errors of less than one nanosecond. After applying the derived time delays to the beamformer, the beam shows residuals of less than $20\%$ with respect to the theoretical beam shape. Tied-array holography could be a way towards semi-real-time beam calibration for the Square Kilometer Array.

description: We report here a distinct reaction, which generates aryl radicals from aryl pinacol boronates under mild aqueous conditions and can be used for peptide and protein modifications. The strategy leverages the versatile reactivity of aryl pinacol boronates to form aryl radicals in presence of ammonium persulfate (APS). The formed aryl radicals insert readily into peptide disulfide bonds while tolerating other functionalities. On the protein level, the reactivity extends beyond the disulfide bonds. The methodology benefits from the accessibility of starting aryl pinacol boronates, as well as biocompatible conditions. In contrast to conventional methods used for aryl radical generation, the strategy is metal‐free, does not require photoinduction and can be readily performed under aqueous conditions. The mechanism of the reactions was investigated by radical‐trapping experiments, spectroscopic analysis and oxygen scavenging. The presented approach broadens the application of aryl pinacol boronate esters in radical reactions.

description: Sen has recently drawn attention to an exact time-dependent Boundary Conformal Field Theory with the space-time interpretation of brane creation and annihilation. An interesting limit of this BCFT is formally equivalent to an array of D-branes located in imaginary time. This raises the question: what is the meaning of D-branes in imaginary time? The answer we propose is that D-branes in imaginary time define purely closed string backgrounds. In particular we prove that the disk scattering amplitude of m closed strings off an arbitrary configuration of imaginary branes is equivalent to a sphere amplitude with m+1 closed string insertions. The extra puncture is a specific closed string state, generically normalizable, that depends on the details of the brane configuration. We study in some detail the special case of the array of imaginary D-branes related to Sen's BCFT and comment on its space-time interpretation. We point out that a certain limit of our set-up allows to study classical black hole creation and suggests a relation between Choptuik's critical behavior and a phase-transition a` la Gregory-Laflamme. We speculate that open string field theory on imaginary D-branes is dual to string theory on the corresponding closed string background.

description: This document contains an investigation into the use of plastic containers and cardboard boxes for the storage and transportation of produce for the UBC Farm. Since it began distributing the produce it grows, the UBC Farm has been using plastic crates and totes exclusively, and wishes to know how this practice compares to alternative methods. To answer this, environmental, economic, and social factors are taken into account when comparing the performance of cardboard boxes and plastic containers. The containers currently in use are superior in the financial and environmental categories and have similar performance to cardboard in the social category. It is recommended that the UBC Farm does not change its current system. Also suggested are several avenues for further investigation that could improve the UBC Farm’s use of plastic containers.

Perception of self and others: A comparison of depressed and nondepressed college students

description: Little is known about the relationship among the three dimensions of Beck's (1967) cognitive triad in depression, negative view of the self, the world, and the future. The present study focuses on the first two by having subjects rate themselves and others. Male and female subjects were classified as depressed or nondepressed on the basis of their Beck Depression Inventory scores (Beck, 1967), giving rise to four groups: Male-Nondepressed, Female-Nondepressed, Male-Depressed, and Female-Depressed. Using a percentile scale, subjects were asked to rate themselves and the average college student of their own sex on a list of 38 variables: some skill-related, some interpersonal, and some emotional. Subjects tended to rate themselves and the average person above the 50th percentile. Since self and average ratings were positively correlated for almost all of the variables in each of the four groups, self rating data were reanalyzed by subtracting the average rating from the self rating in order to obtain an improved index of self perception. Both depressed and nondepressed subjects usually rated themselves better than average, nondepressed subjects doing so more frequently and to a greater degree than depressed subjects. Items for which all subjects evinced a self serving bias seemed to be related to the social aspects of their life circumstances. Some of the 38 variables elicited different ratings from depressed and nondepressed subjects. Others elicited ratings from nondepressed males different from those for the other three groups. A third collection of variables elicited ratings from nondepressed females different from those for the other three groups. Items from the two latter categories shed some light on depressive symptomatology for males and females respectively. The presence of the self serving bias in both depressives and nondepressives may be related to the personal, relevant nature of the items.

description: The birth of the new field of Microplasma Physics, at the turn of the century, follows decades of miniaturization of plasma sources. The empirical Paschen law from the early twentieth century ensures that increasing the pressure allows a reduction in the reactor dimensions and vice versa. However stable operation of a direct current microscopic discharge had been elusive, until the end of the 1990s. At microscopic dimensions the importance of surface reactions is magnified, emphasizing the role of the reactor materials. Diamond, obtained synthetically by Chemical Vapour Deposition, offers unprecedented versatility and robustness. By selecting, during deposition, between insulating and semiconducting thin films, diamond-based micro-reactors were fabricated and operated for the first time. The ignition conditions were similar to results reported with other microplasma sources, in argon and helium at pressures ranging from a few torr to atmospheric pressure. The same abnormal and normal glow modes were obtained by comparing the V-I characteristics with those obained with more common microplasma reactor materials. The dielectric spacer was shown to drive heat transfer through the reactor. Its role on the microplasma was studied via gas temperature measurements. Measurements in diamond were compared with glass-based results. Occupying opposite ends of the thermal conductivity spectrum, they led to significantly different results. Owing to the excellent thermal conductivity of diamond, gas temperature decreased with reactor diameter. That is, heat transfer through the dielectric prevailed over that through the gas phase. To the contrary, glass-based microdischarges were hotter at smaller diameters, when heat conduction through the dielectric was too poor. Finally, diamond outlived glass and is poised to become a material of choice for microplasma research. Indeed, no diamond-based reactors suffered any failure from the microplasma operation, showing signs of long lifetime.

description: Thanks to recent measurements of tidal deformability and radius, the nuclear equation of state and structure of neutron stars are now better understood. Here, we show that through resonant tidal excitations in a binary inspiral, the neutron crust generically undergoes elastic-to-plastic transition, which leads to crust heating and eventually meltdown. This process could induce $\sim \mathcal{O}(0.1)$ phase shift in the gravitational waveform. Detecting the timing and induced phase shift of this crust meltdown will shed light on the crust structure, such as the core-crust transition density, which previous measurements are insensitive to. A direct search using GW170817 data has not found this signal, possibly due to limited signal-to-noise ratio. We predict that such signal may be observable with Advanced LIGO Plus and more likely with third-generation gravitational-wave detectors such as the Einstein Telescope and Cosmic Explorer.

Minimal nonlinear modal aeroelastic descriptions for highly flexible aircraft control
Creators: name: Artola, Marc
Publisher: name: Imperial College London
Year: 2021

description: The increase in aircraft structural flexibility, resulting from the use of slender wings and composite light-weight materials, to improve aerodynamic efficiency, poses a severe control problem. The dynamics of these vehicles, described by nonlinear mathematical models, are complex, with large wing deformations that significantly affect the vehicle flight mechanics and make them vulnerable to disturbances or adverse atmospheric conditions. Therefore, advanced control methodologies capable of accounting for the nontrivial dynamics of such aircraft are required to improve their manoeuvrability and ensure their structural integrity. We propose a control framework that employs a model predictive controller and its dual moving horizon estimator. These strategies are highly suitable to address this challenge, since they rely on solving optimal control problems which are constrained by arbitrary nonlinear dynamics and can explicitly account for state and actuator constraints. With available proofs on stability and algorithmic improvements to enable real-time application, the focus of this work is placed on deriving efficient characterisations that encapsulate the relevant dynamics of these complex systems for successful control. The conceived internal models for control build upon a recently developed geometricallyexact beam description, known as the intrinsic formulation. It uses velocities and strains as main variables, which leads to a compact mathematical model, amenable to efficient nonlinear model-order reduction using the structural modes of vibration. These are also used to project the typically high-dimensional inputs and outputs of a linearised unsteady vortex lattice formulation onto lower dimensional subsets. This enables efficient model order reduction of its state-space representation and establishes a common fluid-structure interface facilitating the aeroelastic coupling. Finally, data-driven modelling is explored to improve known limitations of the coupled aeroelastic models and further optimise their size for control. The resulting framework, able to operate in the nonlinear regime, allows for exploration of unconventional control and stabilisation mechanisms as shown in the numerical examples, which would be unattainable with traditional control methods.

description: Awaous Valenciennes, 1837
 Gobius gutum Hamilton, 1822, from India has been considered a junior synonym of Glossogobius giuris by Kottelat (2013). However, the original description, clearly indicates that the upper jaw overhangs the lower jaw, unlike Glossogobius. Hora (1929) published Hamilton’s original drawing of Gobius gutum and it is clearly a species of Awaous. Britz (2019) provided the image in colour and added the type locality as Podma River. Plamoottil (2016) recorded and figured the species as Awaous gutum.
 Gobius neglectus Jerdon, 1949. Although not treated by Koumans (1953) the species was originally compared with species of Glossogobius. The species was described as having a sloping snout and an eye going into head length 5 times. The counts are given as D 6 I,11 and anal I,10 or 11. Under Gobius kokius Jerdon (1849) describes the snout as being in line with the back and D I,9 anal I,8. That species is consistent with the “giuris” head form, but neglectus is a closer match to Awaous, although it is reported from near the mountain and may belong elsewhere, but is clearly not a Glossogobius.

description: The attachment of proteins to the cell membrane using a glycosylphosphatidylinositol (GPI) anchor is a ubiquitous process in eukaryotic cells. Deficiencies in the biosynthesis of GPIs and the concomitant production of GPI-anchored proteins lead to a series of rare and complicated disorders associated with inherited GPI deficiencies (IGDs) in humans. Currently, there is no treatment for patients suffering from IGDs. Here, we report the design, synthesis, and use of GPI fragments to rescue the biosynthesis of GPI-anchored proteins (GPI-APs) caused by mutation in genes involved in the assembly of GPI-glycolipids in cells. We demonstrated that the synthetic fragments GlcNAc-PI (1), Man-GlcN-PI (5), and GlcN-PI with two (3) and three lipid chains (4) rescue the deletion of the GPI biosynthesis in cells devoid of the PIGA, PIGL, and PIGW genes in vitro. The compounds allowed for concentration-dependent recovery of GPI biosynthesis and were highly active on the cytoplasmic face of the endoplasmic reticulum membrane. These synthetic molecules are leads for the development of treatments for IGDs and tools to study GPI-AP biosynthesis.

description: Almost all research on superintegrable potentials concerns spaces of constant curvature. In this paper we find by exhaustive calculation, all superintegrable potentials in the four Darboux spaces of revolution that have at least two integrals of motion quadratic in the momenta, in addition to the Hamiltonian. These are two-dimensional spaces of nonconstant curvature. It turns out that all of these potentials are equivalent to superintegrable potentials in complex Euclidean 2-space or on the complex 2-sphere, via "coupling constant metamorphosis" (or equivalently, via Staeckel multiplier transformations). We present tables of the results.

 Gobius phaiospilosoma Bleeker, 1849. The species was described with a size given of 46 mm TL from Pasuruan, Sumanap Regency, east Java Province on Madurae Strait from estuarine waters. It is unclear whether the species was described from a single specimen or multiple specimens. A possible holotype is RMNH 4456, 34 mm SL. The caudal is damaged, but total length would be expected around 40–42 mm TL. The second dorsal and anal ray counts are I,8 of the possible holotype. Bleeker recorded I,9, but probably counted the last branched ray as a separate ray. The predorsal scale count is 10, very low for a Glossogobius. The sensory papillae are arranged in multiple vertical rows on the lower cheek, characteristic of some species of Favonigobius. The tongue is rounded, and clearly the species is not a Glossogobius and assigned here as a valid species of Favonigobius. Most species of Favonigobius have few or no predorsal scales.

description: On a very basic level those who study suicide are either explicitly or implicitly concerned with the certification of suicide deaths by coroners and medical examiners. Although many authors have questioned the accuracy of officially reported rates, these statistics continue to be quoted as fact, a potentially problematic practice for researchers who seek accurate and true causative factors for suicidal behavior. The virtual absence of any determination criteria for suicide has been cited as a possible key source of error and variability in officially reported suicide statistics. To address this concern, an exploratory case study experiment was conducted to test the potential impact of expert suicide determination criteria on medical examiners' and lay-coroners' medicolegal certifications of death. The study showed that expert criteria had no impact on manner of death determination or certainty of certification. This result may have stemmed from inadequacies in the criteria, the high expertise of the sampled officials, or methodological problems in the study (e.g., resulting in respondent failure to use the criteria). The first of these interpretations was addressed in the second part of this project by a survey investigation which evaluated the 22 expert-derived suicide determination criteria and 33 additional items obtained from the literature. A checklist of these items was used to collect data on a sample of 126 recent suicides and accidents investigated by 70 medical examiners. The data were divided into two separate (normative and concurrent) sets for analyses, Initial analysis of the normative data empirically confirmed that medical examiners define suicide as a self-inflicted death in which there is intent to die. Therefore, these data were used to construct an instrument to predict self-infliction and intention. This instrument proved to be a 16 item subset of the original 55 items. When validated against the concurrent data, its reliability was.869 for self-infliction scoring and.876 for intention scoring. Validity was.898 for self-infliction scoring and.843 for intention scoring. This instrument predicted 100% of suicides and 83% of accidents in the concurrent sample, thus correctly identifying 93% of all cases.

description: The purpose of this study was to identify factors which affect the performance of students on the computation/mathematics subtest of the Florida College-Level Academic Skills Test. Subjects in the study were 385 students at two private Florida colleges, who were Florida residents and had taken the CLAST between fall 1985 and spring 1987. Data collected on the students included: information on high school and college mathematical backgrounds; racial composition of high school from which they graduated; high school class rank; SAT/ACT math scores; college GPAs in mathematics and overall; race, sex, and age; CLAST mathematics subtest scores. Multiple regression analysis was used with the CLAST score as the dependent variable. Overall, the results of the study indicated that performance on the mathematics subtest of the CLAST is determined to a great extent by factors determined before the student has entered college: racial composition of high school, and SAT scores. In addition, the overall college GPA had a significant influence. The number of remedial math courses taken in college was found to affect the CLAST score significantly, but in a negative fashion. Conclusions from the study were: (1) the predictability value of the SAT score should not be ignored if students are expected to exhibit competency based on standardized test scores after college entrance; (2) the content of remedial mathematics course taken in college should be carefully examined to determine relevance to competencies expected to be achieved before taking the CLAST; (3) articulation programs between colleges and high schools should be established in order to overcome low-level math course tracking and low teacher and student expectations of black students in predominantly white schools.

description: We develop here a new approach for the relativistic modeling of the photons moving into a quasi-Minkowskian space-time, where the metric is generated by an arbitrary n-body distribution within an isolated Solar System. Our model is built on the prescriptions of the theory of General Relativity and leaves the choices of the metric, as well as that of the motion of the observer, arbitrary. Adopting a quasi-Minkowskian expression of the metric accurate to order (v/c)^2, a thorough numerical test campaign is conducted to verify correctness and reliability of the model equations. The test results show that the model behaves according to predictions. Specifically, comparisons to true (simulated) data demonstrate that stellar distances are reconstructed up to the specified level of accuracy. Although the (v/c)^2 approximation is not always sufficient for its application to future astrometric experiments, which require modeling to (v/c)^3, this work serves also as a natural test-ground for the higher order model, whose formulation is now close to completion, and will be presented in a forthcoming paper.

description: Die nicht-alkoholische Fettlebererkrankung (NAFLD) ist die häufigste chronische Lebererkrankung im Kindes- und Jugendalter und ätiologisch mit der Adipositas und der einhergehenden metabolischen Dysregulation assoziiert. Das Erkrankungsspektrum der NAFLD umfasst die benigne nicht-alkoholische Fettleber (NAFL) und die nicht-alkoholische Steatohepatitis (NASH), welche potentiell eine fortschreitende Leberfibrose bis hin zur NASH-assoziierten Leberzirrhose bedingen kann. In der vorliegenden Arbeit wurden genetische, lipidomische und radiologische Merkmale der pädiatrischen NAFLD untersucht. In einer Studie zur genetischen Prädisposition wurden 14 aus der Erwachsenenmedizin bekannte Einzelnukleotid-Polymorphismen in einer pädiatrischen Kohorte evaluiert. Hier wurde die Bedeutsamkeit der PNPLA3 148M Risikovariante sowohl für die Entwicklung der NAFLD als auch für den histologischen Schweregrad bei Kindern und Jugendlichen bestätigt. In der Untersuchung lipidomischer Profile aus dem Lebergewebe zeigte sich eine positive Assoziation bioaktiver Epoxyeicosanoide mit dem Grad der Steatose, während die Aktivität der Cytochrom P450 Epoxygenasen, als entscheidender enzymatischer Bildungsweg der Epoxyeicosanoide, mit steigendem Grad der Fibrose eingeschränkt war. Die Elastographie als radiologische Modalität zur Leberfibrosemessung wurde sowohl Ultraschall- als auch Magnetresonanz-basiert angewandt. Beide Methoden ergaben eine hohe diagnostische Genauigkeit in der Detektion moderater oder fortgeschrittener Fibrose. Weiterhin wurde ein neuer histologischer Score unter Einbeziehung der zonalen Verteilungsmuster der pädiatrischen NAFLD entwickelt. In der Zusammenschau zeigen die Ergebnisse der Arbeiten Beispiele für eine präzisere klinische Risikostratifizierung, ein nicht-invasives Monitoring und neue Konzepte zur therapeutischen Intervention der NAFLD im Kindes- und Jugendalter auf.

description: Follow-up neutron measurements, performed on a sample much larger than the one used in the original study, show that in the energy range 0.5-45 meV the magnetic excitations in BaCu2SiGeO7 are indistinguishable from those in conventional (disorder-free) quantum S=1/2 chains. Scrutinizing the previous data, we found that the analysis was affected by a poorly identified structured background and an additional technical mistake in the data reduction.

description: Psammogobius Smith, 1936
 Although often treated as a synonym of Glossogobius, Hoese et al. (2015) provided detailed morphological reasons for recognising the genus.
 Gobius sublitus Cantor, 1849. The species was described from Malaysia. The holotype is a varnished skin and clearly has a lappet over the eye and a broad gill opening indicating Psammogobius. Two species are being confused under the name Psammogobius biocellatus: P. biocellatus with opercular scales and fully scaled predorsal and a second species without opercular scales and reduced predorsal scales. The second species probably has a name, but we have not examined sufficient type material to be sure of the appropriate name. Psammogobius biocellatus is known from the Indian Ocean and western Pacific, but the second species is only known from the western and central Pacific.

description: We study a transition between a homogeneous and an inhomogeneous phase in a system of one-dimensional, Raman tunnel-coupled Bose gases. The homogeneous phase shows a flat density and phase profile, whereas the inhomogeneous ground state is characterized by periodic density ripples, and a soliton staircase in the phase difference. We show that under experimentally viable conditions the transition can be tuned by the wavevector difference $Q$ of the Raman beams and can be described by the Pokrovsky-Talapov model for the relative phase between the two condensates. Local imaging available in atom chip experiments allows to observe the soliton lattice directly, while modulation spectroscopy can be used to explore collective modes, such as the phonon mode arising from breaking of translation symmetry by the soliton lattice. In addition, we investigate regimes where the cold atom experiment deviates from the Pokrovsky-Talapov field theory. We predict unusual mesoscopic effects arising from the finite size of the system, such as quantized injection of solitons upon increasing $Q$, or the system size. For moderate values of $Q$ above criticality, we find that the density modulations in the two gases interplay with the relative phase profile and introduce novel features in the spatial structure of the mode wave-functions. Using an inhomogeneous Bogoliubov theory, we show that spatial quantum fluctuations are intertwined with the emerging soliton staircase. Finally, we comment on the prospects of the ultra-cold atom setup as a tunable platform studying quantum aspects of the Pokrovsky-Talapov theory in and out-of-equilibrium.
