Game-based cognitive measure

description: Concept formation is a term that refers to the ability to create abstract categories and rules for the objects in our environment. It is an ability that develops throughout childhood, and is important in education and learning. However, there are limited concept formation measures for six- and seven-year-old children, many of which are adaptations from adult tests. The present study seeks to explore the utility of a game-based task, called the Alien Game, originally designed by Pavitt (2017) as a child-friendly and culturally fairer measure of concept formation.

In this cross-sectional study, 13 six- and seven-year-old participants, completed the Alien Game, and WISC-IV Similarities and Matrix Reasoning. Teachers completed working memory and inhibition ratings. The concurrent validity, applicability and likability of the Alien Game were explored.

The Alien Game Abstraction score (AS) had high applicability as a reflection of children’s strategy based on concept formation. Spearman’s Rank correlation tests found a good concurrent validity of AS with Similarities and Matrix Reasoning scores, indicating that the AS is a good measure of concept formation. The AS had low predictive validity of working memory and inhibition. The Alien Game was rated highly by participants, who preferred it to established measures of concept formation.

The Alien Game merits further development as a concept formation measure for six- and seven-year-old children. Further development should involve replication with a larger sample, analysis of the relationship between culture and performance in the Alien Game, and clinical utility for children with neurodevelopmental diagnoses and brain injury.

Farm Management

description: The objective of this paper is to provide a framework of accounting to allow the evaluation and comparison of both conventional and traditional agriculture by accounting for both traditional market transactions and the environmental resources and changes in those resources. Even if a study estimates the value of the change in the resource inventory, the correction to the farmer's financial condition is not made in an explicit way. Again, the study by Faeth et al. makes a strong contribution to the need to have such an accounting system for farms. Farmers should be interested in this information because it is their own backyard where they are working, living and using their own assets. We start with a brief review of the work done with national accounts and then move to accounting on individual farms.

description: The interaction between extratropical cyclones and the underlying boundary layer has been a topic of recent discussion in papers by Adamson et. al. (2006) and Beare (2007). Their results emphasise different mechanisms through which the boundary layer dynamics may modify the growth of a baroclinic cyclone. By using different sea-surface temperature distributions and comparing the low-level winds, the differences are exposed and both of the proposed mechanisms appear to be acting within a single simulation.

description: The objective of this paper is to improve our knowledge of how the traditional goals of income and risk reduction may affect farmers' choice of production methods especially those that are more environmentally sensitive. The distribution of net cash flows for alternative crop production methods or strategies were estimated. These distributions were compared to predict whether the traditional goals of income level and risk avoidance will be at odds with environmental goals or whether farmers can find production strategies that support both types of goals. Previous studies have used average yields and conditions to find that alternative tillage systems have lower costs that conventional systems (e.g., Smolik, Dobbs, and Rickerl; Weersink et al.) Salin, Dobbins, and Preckel estimated the distribution of net returns of different tillage systems but used only yield variation with no correlations. This paper extends their work by incorporating price variation and correlations between yields and prices. This study uses data from the initial years of a long-time, systems study in southwestern Minnesota. Even though the concept of sustainability in crop production involves a long-term, systems view of the use of natural resources, most studies have focused on single crop or single treatment effects. To address this lack of long-term, systems comparisons, two such studies were initiated near Lamberton in southwestern Minnesota in 1989: the Minnesota variable input crop management systems trials (VICMS I and II). Similar studies have begun in Wisconsin (Posner et al., 1995) and Italy (Giupponi, Olson, and Rosato, 1993). The emphasis of this paper is on whole systems analysis of the economic consequences of the transition to different production strategies.

description: We investigate a quantum vacuum state for $1 + 1$ dimensional de Sitter space, corresponding to a region within a perfectly reflecting symmetric box of fixed physical size. We find that a particle detector inside the box registers zero response, implying that the walls of the box screen out the thermal effects of the de Sitter horizon. The box thus creates a `quiescent oasis' with a temperature below the de Sitter horizon temperature, an unexpected feature that opens the way to an analysis of heat and entropy exchange between the box and the horizon in the context of the generalized second law of thermodynamics. We also calculate the stress-energy-momentum tensor of the region within the box, showing that the total energy in the box is less than the same volume of de Sitter space in the presence of thermal fluctuations.

description: The IoT is set to permeate our lives as a new and global super infrastructure, where billions of devices with an unprecedented variety of hardware architectures will interact. To enable IoT applications and services to run everywhere without major adaptation, operating systems (OS) provide standardized interfaces to the heterogeneous hardware. As a consequence, an operating system for IoT devices must be available for a huge number of target platforms, from low-end to high-end devices, and it must guarantee different levels of dependability (e.g., safety, security, real-time, maintainability) that each application will require. Some of these hardware architectures do already exist, others will emerge over time and introduce new or improved features that must be supported or exploited by the OS. In order to succeed, an OS must thus be portable, not only concerning its functionality, but also its verified dependability. This paper tries to answer the question of how portable existing IoT OSs are, analyzing five popular OSs on their design, development, and testing processes, as well as the quality of available ports. We close with a suggestion on how to improve portability for future OS designs.

description: Among unidentified gamma-ray sources in the galactic plane, there are some that present significant variability and have been proposed to be high-mass microquasars. To deepen the study of the possible association between variable low galactic latitude gamma-ray sources and microquasars, we have applied a leptonic jet model based on the microquasar scenario that reproduces the gamma-ray spectrum of three unidentified gamma-ray sources, 3EG J1735-1500, 3EG J1828+0142 and GRO J1411-64, and is consistent with the observational constraints at lower energies. We conclude that if these sources were generated by microquasars, the particle acceleration processes could not be as efficient as in other objects of this type that present harder gamma-ray spectra. Moreover, the dominant mechanism of high-energy emission should be synchrotron self-Compton (SSC) scattering, and the radio jets may only be observed at low frequencies. For each particular case, further predictions of jet physical conditions and variability generation mechanisms have been made in the context of the model. Although there might be other candidates able to explain the emission coming from these sources, microquasars cannot be excluded as counterparts. Observations performed by the next generation of gamma-ray instruments, like GLAST, are required to test the proposed model.

description: The reform process of the CAP has been, till now, driven by market and financial factors. The Mid Term Review, however, reveals that new important issues have emerged. The impact of the next main events, the ongoing WTO Round and the enlargement, on the CAP are examined. The analysis shows that the Mid Term Review is mainly inspired by an attempt to deliver a prompt political response to the concerns of EU citizens, although, on the market side, it goes beyond the line drawn by Agenda 2000 anticipating part of the reform supposed to be needed after 2006 in preparation of the CAP for the enlarged EU. The new tools introduced by the Proposal may be seen to contribute at restoring market conditions in the EU agricultural sector and at promoting higher level of positive externalities output. After a preliminary examination of the new reform Proposal, the document highlights the main difficulties it may encounter in the approval process, the questions that need to be explored and the inconsistencies with the main long term goal of the 'European model of agriculture.'

description: The possibility to use the ultrashort ion bunches produced by circularly polarized laser pulses to drive a source of fusion neutrons with sub-optical cycle duration is discussed. A two-side irradiation of a thin foil deuterated target produces two countermoving ion bunches, whose collision leads to an ultrashort neutron burst. Using particle-in-cell simulations and analytical modeling, it is evaluated that, for intensities of a few $10^{19} W cm^{-2}$, more than $10^3$ neutrons per Joule may be produced within a time shorter than one femtosecond. Another scheme based on a layered deuterium-tritium target is outlined.

description: The free lunch is over – again? In 2004, Herb Sutter observed the stagnation of clock frequencies and predicted hyperthreading and multicore capabilities as drivers for performance growth on CPUs. This prediction and the resulting advice to focus more on concurrency to achieve sustainable application performance, has become the daily reality of HPC software engineers. In this paper, we compare trends in the development of CPU and GPU architectures and examine their implications for the parallelization and portability of HPC software. The data analysis still reveals levelling clock frequencies but this time also for GPUs. Additionally, an increasing amount of hardware parallelism can be observed for both architectures.

description: We report Chandra ACIS observations of the fields of 4 QSOs showing strong extended optical emission-line regions. Two of these show no evidence for significant extended X-ray emission. The remaining two fields, those of 3C 249.1 and 4C 37.43, show discrete (but resolved) X-ray sources at distances ranging from ~10 to ~40 kpc from the nucleus. In addition, 4C 37.43 also may show a region of diffuse X-ray emission extending out to ~65 kpc and centered on the QSO. It has been suggested that extended emission-line regions such as these may originate in the cooling of a hot intragroup medium. We do not detect a general extended medium in any of our fields, and the upper limits we can place on its presence indicate cooling times of at least a few 10^9 years. The discrete X-ray emission sources we detect cannot be explained as the X-ray jets frequently seen associated with radio-loud quasars, nor can they be due to electron scattering of nuclear emission. The most plausible explanation is that they result from high-speed shocks from galactic superwinds resulting either from a starburst in the QSO host galaxy or from the activation of the QSO itself. Evidence from densities and velocities found from studies of the extended optical emission around QSOs also supports this interpretation.

description: Almost all properties of a photodissociation region (PDR) depend on its metallicity. The heating and cooling efficiencies that determine the temperature of the gas and dust, the dust composition, as well as the elemental abundances that influence the chemical structure of the PDR are just three examples that demonstrate the importance of metallicity effects in PDRs. PDRs are often associated with sites of star formation. If we want to understand the star formation history of our own Galaxy and of distant low-metallicity objects we need to understanding how metallicity acts on PDR physics and chemistry.

description: Let $n>1$, $e\geq 0$ and a prime number $p\geq 2^{n+2+2e}+3$, such that the index of regularity of $p$ is $\leq e$. We show that there are infinitely many irreducible Galois representations $ρ: Gal(\bar{\mathbb{Q}}/\mathbb{Q})\rightarrow {GL}_n(\mathbb{Q}_p)$ unramified at all primes $l\neq p$. Furthermore, these representations are shown to have image containing a fixed finite index subgroup of ${SL}_n(\mathbb{Z}_p)$. Such representations are constructed by lifting suitable residual representations $\barρ$ with image in the diagonal torus in ${GL}_n(\mathbb{F}_p)$, for which the global deformation problem is unobstructed.

description: The $^3$He$(e,e^\prime p)$$d$ reaction is studied using an accurate three-nucleon bound state wave function, a model for the electromagnetic current operator including one- and two-body terms, and the Glauber approximation for the treatment of final state interactions. In contrast to earlier studies, the profile operator in the Glauber expansion is derived from a nucleon-nucleon scattering amplitude, which retains its full spin and isospin dependence and is consistent with phase-shift analyses of two-nucleon scattering data. The amplitude is boosted from the center-of-mass frame, where parameterizations for it are available, to the frame where rescattering occurs. Exact Monte Carlo methods are used to evaluate the relevant matrix elements of the electromagnetic current operator. The predicted cross section is found to be in quantitative agreement with the experimental data for values of the missing momentum $p_{\rm m}$ in the range (0--700) MeV/c, but underestimates the data at $p_{\rm m} \simeq 1$ GeV/c by about a factor of two. However, the longitudinal-transverse asymmetry, measured up to $p_{\rm m} \simeq$ 600 MeV/c, is well reproduced by theory. A critical comparison is carried out between the results obtained in the present work and those of earlier studies.

Bless Your Heart: A Deconstruction of Southern Hostility Disguised as Southern Hospitality and its Effects on Black Identity in Blues for Mister Charlie and The Vanishing Half
Creators: name: Neill, Sterling
Publisher: name: Georgia State University
Year: 2023

description:
Southern hospitality, whether real or perceived, is a cultural stereotype tied to the Southern region of the United States. Studies on Southern hospitality are growing, possibly due to the recent surge of anti-Black legislation including disbandment of Affirmative Action, critical race theory, and women and gender studies in schools. As more racist and sexist doctrine is dispersed throughout America, it is imperative to evaluate false narratives, such as Southern hospitality, that perpetuate and reinforce structural discrimination, which historical literary works can function to counter. This thesis examines Blues for Mister Charlie by James Baldwin and The Vanishing Half by Brit Bennett, to divulge their perspectives on Southern hospitalitys prompting of guise and performance, giving rise to what I term Southern hostility. I posit that these works reveal the true American past, exposing performative allyship and victimhood by Whites and identity struggles for Blacks to critique issues surrounding race and identity.
Camber Design Study for Concrete Pipe Culvert
Creators: name: Deen, Robert C.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1964
Subjects: subject: Transportation Engineering

description: When a pipe culvert is constructed on or near the natural ground surface and covered by a highway fill or embankment, the weight of the embankment compresses and consolidates the foundation soil, settlement occurs, and the culvert subsides and sags below the original grade line. Experience has shown that culverts which become clogged with silt and debris, become disjointed and faulted, leak, become undermined, and endanger the stability of the embankment. These and other damages attendant to settlement restrict the flow of water, prevent adequate inspection of the structure, and may eventually require extensive maintenance or complete replacement of the structure. Some of this damage may be avoided by placing the culvert on cambered grades--that is, by installing the culvert with its flow line somewhat above its normal or desired elevation along the central portion of its length. This idea anticipates that settlement under the load of the embankment will, in time, lower the flow line to the desired straight grade.  The project reported in this paper was undertaken to develop a simplified criterion which would permit the inclusion of camber as a routine design feature in highway culvert installations. The work was based on the theory of consolidation and consisted of consolidation tests and prediction of settlement profiles under proposed embankments, the installation of these culverts cambered according to the predicted settlement profiles, and the observance of the settlements during and following the completion of the embankments. Fairly close agreement between the predicted and observed settlements invited serious speculation as to the possibility of estimating camber, within reasonable limitations, from typical void ratio-pressure curves obtained from typical or average soils.

description: Spoken language understanding (SLU) requires a model to analyze input acoustic signal to understand its linguistic content and make predictions. To boost the models' performance, various pre-training methods have been proposed to learn rich representations from large-scale unannotated speech and text. However, the inherent disparities between the two modalities necessitate a mutual analysis. In this paper, we propose a novel semi-supervised learning framework, SPLAT, to jointly pre-train the speech and language modules. Besides conducting a self-supervised masked language modeling task on the two individual modules using unpaired speech and text, SPLAT aligns representations from the two modules in a shared latent space using a small amount of paired speech and text. Thus, during fine-tuning, the speech module alone can produce representations carrying both acoustic information and contextual semantic knowledge of an input acoustic signal. Experimental results verify the effectiveness of our approach on various SLU tasks. For example, SPLAT improves the previous state-of-the-art performance on the Spoken SQuAD dataset by more than 10%.

description: We propose Corder, a self-supervised contrastive learning framework for source code model. Corder is designed to alleviate the need of labeled data for code retrieval and code summarization tasks. The pre-trained model of Corder can be used in two ways: (1) it can produce vector representation of code which can be applied to code retrieval tasks that do not have labeled data; (2) it can be used in a fine-tuning process for tasks that might still require label data such as code summarization. The key innovation is that we train the source code model by asking it to recognize similar and dissimilar code snippets through a contrastive learning objective. To do so, we use a set of semantic-preserving transformation operators to generate code snippets that are syntactically diverse but semantically equivalent. Through extensive experiments, we have shown that the code models pretrained by Corder substantially outperform the other baselines for code-to-code retrieval, text-to-code retrieval, and code-to-text summarization tasks.

A Study of the Effects of Quick Freezing on Saturated Fragments of Rocks

Year: 1964
Subjects: subject: Transportation Engineering

description: Quick freezing of a fragment of rock which is fully saturated with water is, perhaps, the most rigorous of all tests for soundness, durability, or resistance to weathering. So-called soundness or quality tests employed currently, or heretofore, for evaluating concrete aggregates are usually less rigorous inasmuch as the state of saturation at the outset of freezing is not at a critical level. Hence, the number of freeze-thaw cycles endured by a rock specimen undergoing freezing and thawing in the presence of available water may merely reflect the duration of the exposure before the rock becomes vulnerable to damage -- i.e., time required for critical saturation. Damage arises wholly from the combined effects of the volume dilation accompanying the freezing of absorbed water, the dilation pressure induced, and the inherent restraining strength of the aggregate particle. Thus, the severest freezing condition, to which rock or concrete may be exposed, occurs after long periods of sustained wetting -- when the degree of saturation is the highest.

For the two oxygen phonon modes found in Raman experiments, $A_{1g}$ and $E_{1g}$, we calculate the matrix elements of the electron-phonon interaction. Analyzing the feedback effect of the conduction electrons on the phonon frequency we compare the calculated and experimentally observed doping dependence of the $A_{1g}$ mode. Furthermore, due to the momentum dependence of the electron-phonon coupling for the $E_{1g}$ symmetry we find no renormalization of the corresponding phonon frequency which agrees with experiment. Our results shed light on the possible importance of the electron-phonon interaction in this system.

description: The Drakesboro-Paradise Road (KY 176), extending 2.84 miles from its junction with KY 70 at Drakesboro to a point on KY 176 approximately 1.8 miles southwest of Paradise, was surfaced in early August with a 1 1/4-in, course of Class I, Type A bituminous concrete containing 40 percent wet-bottom-boiler slag from the T.V.A. power plant at Paradise, Kentucky. The use of the slag was on an experimental basis, and the objective was to determine the feasibility of utilizing the slag as an anti-skid aggregate in other, high-type,bituminous surfacing in that area. A laboratory investigation preceded the field experiment, and the results therefrom have been reported previously. Previous experiences with the use of the slag in seal-coats and slurry-seals have also been reported.

description: We propose that the solar neutrino deficit may be due to oscillations of mass-varying neutrinos (MaVaNs). This scenario elucidates solar neutrino data beautifully while remaining comfortably compatible with atmospheric neutrino and K2K data and with reactor antineutrino data at short and long baselines (from CHOOZ and KamLAND). We find that the survival probability of solar MaVaNs is independent of how the suppression of neutrino mass caused by the acceleron-matter couplings varies with density. Measurements of MeV and lower energy solar neutrinos will provide a rigorous test of the idea.

description: Let X be a pointed connected simplicial set with loop group G. The linearisation map in K-theory as defined by Waldhausen uses G-equivariant spaces. This paper gives an alternative description using presheaves of sets and abelian groups on the simplex category of X. In other words, the linearisation map is defined in terms of X only, avoiding the use of the less geometric loop group. The paper also includes a comparison of categorical finiteness with the more geometric notion of finite CW objects in cofibrantly generated model categories. The application to the linearisation map employs a model structure on the category of abelian group objects of retractive spaces over X.

description: The ANtarctic Impulsive Transient Antenna (ANITA) long-duration balloon experiment is sensitive to interactions of ultra high-energy (E > 10^{18} eV) neutrinos in the Antarctic ice sheet. The third flight of ANITA, lasting 22 days, began in December 2014. We develop a methodology to search for energetic neutrinos spatially and temporally coincident with potential source classes in ANITA data. This methodology is applied to several source classes: the TXS 0506+056 blazar and NGC 1068, the first potential TeV neutrino sources identified by IceCube, flaring high-energy blazars reported by the Fermi All-Sky Variability Analysis, gamma-ray bursts, and supernovae. Among searches within the five source classes, one candidate was identified as associated with SN 2015D, although not at a statistically significant level. We proceed to place upper limits on the source classes. We further comment on potential applications of this methodology to more sensitive future instruments.

title: Developing Bare-Metal GPGPU Drivers From Scratch: What prevents scientists from developing own GPGPU drivers?
Creators: name: Lütke Dreimann, Marcel

subject: GPU documentation
subject: development challenges

description: Most of modern computers use Graphic Processing Units (GPUs) as an additional source of computing power. However, using GPUs in bare-metal research operating systems comes with some challenges. Existing drivers for Linux or Windows are complex and cannot be used for without much effort. Documentation of modern GPUs is often missing or incomplete and drivers are incomprehensive or closed source. This paper tries to explain what prevents scientists from creating their own GPU drivers. Additionally, it gives an overview about GPGPU driver development for GPUs from different manufactur- ers and shows some challenges. Nevertheless, we have ambitiously started an undertaking to develop our own driver from scratch. To some extend this was successful, but with many problems on the way.

subject: FOS: Economics and business

description: The objective of this study is to identify the relationship between food quality and store's perceived quality and how they effect the perceived value of products. In particular, the organic product's characteristics have been considered. A consumer survey was carried out through a questionnaire. The sample was stratified by purchasing performance of customers: supermarket, specialties' store, grocery's, producers market. The statistical model was devoted to understand the causal interactions among the explanatorial variables rather than their functional structure. For that purpose, path analysis was applied. Specialties' store interacts with food characteristics as following: health, no preservatives, nutrient, good for children, producer identifiable, fresh. Supermarket is associated with: entertainment, convenience, practicity, generic magazines.
A Qualitative Exploration of Self-Perceived Problematic Pornography Use Amongst Young People
Creators: name: Richards, Laura May

Subjects: problematic pornography use

pornography

description: Pornography use is prevalent amongst young people, with technology developments meaning that it is now available like it has never been available before. Research to date has indicated that for a minority of users that this may be problematic for them. However, there had been no research interviewing those who experience this difficulty. This thesis explores the experience of young people with self-perceived problematic pornography use.

Semi-structured interviews were conducted with nine 16–24-year-olds with self-perceived problematic pornography use. The data was analysed from a social constructionist paradigm following Braun and Clarke (2022) reflexive thematic analysis. There were seven themes constructed which are: 1. What is problematic use? Too much or too extreme?, 2. Using porn as a coping strategy, 3. The shame/guilt associated with pornography use, 4. The negative effect of problematic pornography use on relationships, 5. Things can get better, 6. People minimising the problem, and 7. A lacking in education.

The experience of self-perceived problematic pornography use is not a stand-alone issue. It is important when working with people who present with this experience that counselling psychologists hold this in mind, understanding this is not just an individual problem but also a relational one, and that understanding what the client exactly means about the problem is key to supporting them.

This thesis has a very broad scope, and the participants were not a homogenous group aside from age and self-perceived problematic pornography use and the research questions were very open. It could be useful for future research to either look into particular identity groups, or to broaden the research more to people of all ages. It could also be interesting to do quantitative research to investigate whether there is a relationship between pornography use and beliefs about sexual education.

description: Due to power constraints, recent Intel CPUs reduce their frequency when executing AVX2 and AVX-512 instructions. Often, this frequency reduction affects other applications as well, which reduces overall performance and prevents contemporary operating systems from fairly distributing system resources. In our work, we show that these problems are fundamental problems of power-limited computing. We analyze the problems and show a method to quantify the underlying AVX overhead. Based on our analysis, we then describe a set of operating system techniques to improve performance and scheduler fairness. Our results show the importance of active management of hardware-controlled frequency scaling by the OS. Based on this observation, we sketch improved hardware-software interfaces which could further reduce AVX overhead and improve the efficacy of our approach.
Islands for Entanglement Negativity

description: We advance two alternative proposals for the island contributions to the entanglement negativity of various pure and mixed state configurations in quantum field theories coupled to semiclassical gravity. The first construction involves the extremization of an algebraic sum of the generalized Renyi entropies of order half. The second proposal involves the extremization of the sum of the effective entanglement negativity of quantum matter fields and the backreacted area of a cosmic brane spanning the entanglement wedge cross section which also extremizes the generalized Renyi reflected entropy of order half. These proposals are utilized to obtain the island contributions to the entanglement negativity of various pure and mixed state configurations involving the bath systems coupled to extremal and non-extremal black holes in JT gravity demonstrating an exact match with each other. Furthermore, the results from both the proposals match precisely with the island contribution to half the Renyi reflected entropy of order half providing a strong consistency check. We then allude to a possible doubly holographic picture of our island proposals and provide a derivation of the first proposal by determining the corresponding replica wormhole contributions.

A simulation pipeline for the Planck mission

description: We describe an assembly of numerical tools to model the output data of the Planck satellite. These start with the generation of a CMB sky in a chosen cosmology, add in various foreground sources, convolve the sky signal with arbitrary, even non-symmetric and polarised beam patterns, derive the time ordered data streams measured by the detectors depending on the chosen satellite-scanning strategy, and include noise signals for the individual detectors and electronic systems. The simulation products are needed to develop, verify, optimise, and characterise the accuracy and performance of all data processing and scientific analysis steps of the Planck mission, including data handling, data integrity checking, calibration, map making, physical component separation, and power spectrum estimation. In addition, the simulations allow detailed studies of the impact of many stochastic and systematic effects on the scientific results. The efficient implementation of the simulation allows the build-up of extended statistics of signal variances and co-variances. Although being developed specifically for the Planck mission, it is expected that the employed framework as well as most of the simulation tools will be of use for other experiments and CMB-related science in general.

Divisions of a different vein: expressions of African affinity in Afro-Caribbean and African-American poetry
Creators: name: Swanigan, Pamela
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines whether Afro-Caribbean, poets of the English-speaking West Indies and black American poets express differences in their sense of Africa and of being African-descended, and, if so, what the nature of those differences might be. Section I constitutes a brief overview of the slave histories in both regions, so as to suggest some political and sociological bases for the divergent literary expressions of Africa that might emerge. Sections II and III explore a range of written and oral poems, from both regions, that have Africa as a theme or a central reference. In these sections, the pattern that emerges is that West Indian poets generally employ strong and concrete topographical, political, religious and historical images of Africa, and increasingly, over the course of the twentieth century, accept and incorporate the West African component of their racial heritage, whereas black American poets show a vague sense of Africa as a place, refer more often to North Africa (and specifically Pharaohic Egypt, via parallels between the Mosaic era of the Old Testament and the American slave period) than to West African, and, overall, only connect their experiences of being "black" in America explicitly to their West African origins at a couple of points in their poetic history-during the Harlem Renaissance of the 1920s and the Black Power era of the late 1960s and early 1970s. The conclusion suggests that acknowledging and understanding these poetic divergences, as well as the attendant and underlying historical and social divergences, might help ease the tensions that are currently mounting between the black American and West Indian peoples.
