description: Deep learning models for MRI classification face two recurring problems: they are typically limited by low sample size, and are abstracted by their own complexity (the "black box problem"). In this paper, we train a convolutional neural network (CNN) with the largest multi-source, functional MRI (fMRI) connectomic dataset ever compiled, consisting of 43,858 datapoints. We apply this model to a cross-sectional comparison of autism (ASD) vs typically developing (TD) controls that has proved difficult to characterise with inferential statistics. To contextualise these findings, we additionally perform classifications of gender and task vs rest. Employing class-balancing to build a training set, we trained 3$\times$300 modified CNNs in an ensemble model to classify fMRI connectivity matrices with overall AUROCs of 0.6774, 0.7680, and 0.9222 for ASD vs TD, gender, and task vs rest, respectively. Additionally, we aim to address the black box problem in this context using two visualization methods. First, class activation maps show which functional connections of the brain our models focus on when performing classification. Second, by analyzing maximal activations of the hidden layers, we were also able to explore how the model organizes a large and mixed-centre dataset, finding that it dedicates specific areas of its hidden layers to processing different covariates of data (depending on the independent variable analyzed), and other areas to mix data from different sources. Our study finds that deep learning models that distinguish ASD from TD controls focus broadly on temporal and cerebellar connections, with a particularly high focus on the right caudate nucleus and paracentral sulcus.

description: My research study seeks to discover how women of Color and White women victims of sexual harassment respond to their harassment. My study uses a sample of the data collected by the Department of Defense for their 1995 study of sexual harassment in the military. Hierarchical log-linear models were specified to test situational, personal, and organizational factors as predictors of responses. The results showed that situational factors are the most important predictors; the personal and organizational factors were not found to be significant predictors. Also, women of Color and White women were found to have differences in the ways they responded to sexual harassment.

description: An important driver of household dietary diversity is nutrition knowledge which can be improved through access to nutrition information. However, in many rural areas, formal flow of nutrition information is limited, and social networks could play an important role as an informal source of such information. This paper evaluates effects of social network on household dietary diversity in Kenya. Cross sectional data collected from 198 farmers using multi stage sampling technique, was analysed using a Poisson regression model. The results show that the average household dietary diversity of an individual s network members has a positive effect on the dietary diversity of the individual. The effects are more when the network includes at least a strong tie. Household size and farm size also have a positive effect on household dietary diversity. These results imply that farmers social networks could be used as a complementary tool for effective delivery of nutrition education which targets to enhance nutritional quality.

description: Based on the research of Thompson et al. (2002), this paper developed a nonlinear commodity market model to analyze the impacts of China s soybean price control policy on price and welfare. A structural model of China soybean economy and its links to the rest of the world is established to analyze the impacts of policy on the variance of domestic price. Also, a Monte Carlo simulation is adopted to evaluate the domestic welfare change and its distributional effects. Results showed that the policy failed to reduce volatility of domestic price. Its stabilizing effects were offset by increases in world volatility due to the high degree of integration between domestic and international market. An inverse U-type relationship appeared between the price transmission elasticity and the domestic price volatility. The policy led to a net welfare increase to producers in China and a net welfare gain in exporting countries at the expense of loss of consumer welfare and huge budgetary costs.

description: The U.S. Government has supported the price of honey since 1950 by providing market price stability to honey producers to encourage them to maintain sufficient honeybee populations to pollinate important agricultural crops. When honey support prices moved above the average domestic price in the early 1980's, domestic producers began to find it profitable to forfeit their honey to the Government. Packers and food manufacturers found it economical to import lower priced honey for domestic use. However, changes made to the honey program by the Food Security Act of 1985 have reduced forfeitures of honey to the Government and made domestic honey competitive with imports. Government expenditures to operate the honey price support program totaled $525.6 million for fiscal years 1980-88. As of May 3, 1989, over 520 million pounds of the 1980-88 honey crops were forfeited to the Government under the loan program. Most of the forfeited honey has been disposed of through various Federal food distribution programs.
Mere reflection or real bias? An analysis of guests on "Nightline", "MacNeil /Lehrer", and "This Week with David Brinkley"

Publisher: name: American University

description: This research examines news interview guests and their treatment on three of the leading news interview programs, Nightline, The MacNeil/ Lehrer NewsHour, and This Week with David Brinkley. It presents statistical evidence in support of the proposition that the leading television news interview programs practice preferential selection and treatment of news interview guests. Labor representatives appeared on these programs less frequently, spoke later both in news interview segments and in the program overall, were interviewed alone less often, and were given shorter interviews than guests from business and professional occupations. This research also presents case study evidence of selection and treatment bias. The selection case studies resolve a key problem with previous efforts to answer the reflection defense of the news media against charges of bias. They demonstrate that guest selection depends upon who defines the news, rather than the abstract goal of reflection. If different selectors perform guest selection, the result is a different type of guest being selected. The treatment case studies provide compelling evidence of some of the conditions under which differential treatment is both likely and unlikely to occur. Differential treatment in news interviews appears more likely when labor and business representatives are on opposite sides of an issue, when labor representatives challenge other guests in the same interview segment, and when interviews are conducted with high-level labor union officials. Such treatment appears less likely when labor and business representatives appear together on the same side of an issue, when interviews deal with late-breaking news events, and when lead-in news reports clearly favor one side over the other.

description: This paper empirically examines the role of exchange rates, cropland returns, and the real interest rate as determinants of foreign investment in U.S. cropland. Investments from the top six countries of origin were analyzed. Investments from Mexico were also examined because of that country's close physical proximity to the United States. The evidence presented suggests that foreign investment in U.S. cropland is negatively related to the value of the dollar and the level of U.S. real interest rates, and positively related to returns on U.S. cropland.

description: Catheter ablation (CA) is a commonly used treatment for persistent atrial fibrillation (AF). Since its medium/long-term success rate remains limited, preoperative prediction of its outcome is gaining clinical interest to optimally select candidates for the procedure. Among predictors based on the surface electrocardiogram, the dominant frequency (DF) and harmonic exponential decay (g) of the fibrillatory waves ( f -waves) have reported promising but clinically insufficient results. Hence, the main goal of this work was to conduct a broader analysis of the f -wave harmonic spectral structure to improve CA outcome prediction through several entropy-based measures computed on different frequency bands. On a database of 151 persistent AF patients under radio-frequency CA and a follow-up of 9 months, the newly introduced parameters discriminated between patients who relapsed to AF and those who maintained SR at about 70%, which was statistically superior to the DF and approximately similar to g. They also provided complementary information to g through different combinations in multivariate models based on lineal discriminant analysis and report classification performance improvement of about 5%. These results suggest that the presence of larger harmonics and a proportionally smaller DF peak is associated with a decreased probability of AF recurrence after CA.
Global Reach of Italian Fashion: Biki’s Cosmopolitan Legacy

description: The celebration of Giovanni Battista Giorgini’s catwalk show in February 1951 aims to give the historical relevance of an event that wasn’t just an episode, but the result of long and established relations, especially with America. It revealed also an international attitude expressed by Italian fashion practitioners long before Italian fashion was officially recognised. For this reason, some narratives around the different processes of “emancipation from Paris” deserve to be scrutinized in more nuanced narratives. The archive of seamstress and then couturière Elvira Leonardi Bouyeure (1906-1999), aka Biki, offers one of those narratives.

description: The widespread environmental pollutants, polycyclic aromatic hydrocarbons (PAHs), are changed to dihydrodiol epoxides in living systems. Bay-region diol epoxides, as ultimate carcinogens of the PAHs, react with the exocyclic nitrogens of purines of DNA (N-6 of A or N-2 of G). Most PAH diol epoxides make a mixture of adducts that may differ in carcinogenicity, and factors that alter the composition of the mixture may alter the overall carcinogenicity of the mixture. Changes in DNA base sequence were found to alter systematically the ratio of S vs. R configured dA adducts formed by the (+)-(4S,3R,2S,1R) diol epoxide isomer of benzo[c]phenanthrene (BcPh) (Cheh et al., Biochemistry 33, 12911(1994)). This dissertation probed whether S vs. R adduct ratio varied systematically with DNA sequence when other diol epoxides, dG as well as dA targets and methylated vs. nonmethylated cytosine nearest neighbors were employed. With other BcPhDE isomers, changes in sequence were also seen to alter both adduct S vs. R ratio and adduct yield systematically. The decreasing ratio of S vs. R dA adducts as the sequence changed from 5 '-GAT > CAT > TAC > TAG, that was observed with the (4S,3R,2S,1R)-BcPhDE isomer, was also seen with the (+)-(4S,3R,2R,1S)-BcPhDE isomer. The (-)-(4R,3S,2R,1S)-BcPhDE isomer exhibited decreasing S/R dA adduct formation following the pattern 5'-CAT > TAG >> GAT > or ∼ TAC. With BcPhDE isomers, it was observed that methylation of nearest neighbor C to target A systematically affected the S/R dA adduct ratio and had variable effects on adduct yield, but on average the yield increased by about 40%. With (+)-(4R,3S,2S,1R)-dibenz[a,j]anthracene diol epoxides (DBADE), a pattern of S/R dG adduct ratio dependent on the identity of nearest neighbors was not observed. Methylation of a nearest neighbor C also systematically altered the S/R dG adduct ratios, and often greatly increased the adduct yields. With (-)-(4R,3S,2R,1S) DBADE, there also was no obvious pattern linking S/R dG ratios and nearest neighbors.

description: GPU architectures have become popular for executing general-purpose programs. Their many-core architecture supports a large number of threads that run concurrently to hide the latency among dependent instructions. In modern GPU architectures, each SM/core is typically composed of several sub-cores, where each sub-core has its own independent pipeline.
 Simulators are a key tool for investigating novel concepts in computer architecture. They must be performance-accurate and have a proper model related to the target hardware to explore the different bottlenecks properly.
 This paper presents a wide analysis of different parts of Accel-sim, a popular GPGPU simulator, and some improvements of its model. First, we focus on the front-end and developed a more realistic model. Then, we analyze the way the result bus works and develop a more realistic one. Next, we describe the current memory pipeline model and propose a model for a more cost-effective design. Finally, we discuss other areas of improvement of the simulator.

description: We show that when a drop of water is maintained in its Leidenfrost regime, a sound in the form of periodic beats emits from the drop. The process of beat emission involves two distinct frequencies. One component is the frequency of beats itself and second is the frequency of sound in every beat which is emitted when one oscillation in the drop occurs. Experiments have been performed by placing a drop of water over a concave metallic surface and the beats of the drop were recorded by fixing a microphone above the drop. A video camera was also fixed above the drop to record its oscillations. Simple analytical techniques like Fourier and wavelet transforms of the audio signals and image processing of the videos of the drop have been used to gain insight about mechanism of beat emission process. This analysis also helped us in studying the dependence of frequencies, if any, on the radius of the drop and the substrate temperature.

description: Every 5 years, the Forest Service is required to update its estimates of the value of Forest Service grazing. This report provides estimates of the maximum ability of ranchers to pay for Forest Service grazing. Abilities to pay vary greatly depending on the region of the country and assumptions about costs. Based on current cash costs, the value of Forest Service grazing is greater than the grazing fee. Based on longrun economic costs, the value of grazing is less than the grazing fee. In some regions of the United States, the longrun value of grazing is zero. These low longrun values reflect the low returns to cow/calf producers in the period on which this study was based.

description: This work is concerned with phrasing the concepts of fault-tolerant quantum computation within the framework of disordered systems, Bernoulli site percolation in particular. We show how the so-called "threshold theorems" on the possibility of fault-tolerant quantum computation with constant error rate can be cast as a renormalization (coarse-graining) of the site percolation process describing the occurrence of errors during computation. We also use percolation techniques to derive a trade-off between the complexity overhead of the fault-tolerant circuit and the threshold error rate.

Peru purchased $162 million worth of U.S. agricultural commodities in 1988. Agricultural imports from the United States have increased more than sevenfold since 1970. Peru is in a severe slump and is the second largest recipient of P.L.-480 aid in Latin America. Wheat, feed grains, and oilseed products will continue to constitute the major share of U.S. agricultural exports to Peru. Commercial purchases may decrease in the near future, and food aid needs will continue to be substantial.

description: The reformulation of field theory for avoiding self-energy parts in the dynamical evolution has been applied successfully in the framework of the Lee model, [M. de Haan. Ann. Phys., 311, 314-349 (2004)] enabling a kinetic extension of the description. The basic ingredient is the recognition of these self-energy parts. [M. de Haan and C. George. Trends in Statistical Physics 3 (2000), 115] The original reversible description is embedded in the new one and appears now as a restricted class of initial conditions. [M. de Haan and C. George. Prog. Theor. Phys.,109, 881-909 (2003)] This program is realized here in the reduced formalism for a scalar field, interacting with a two-level atom, beyond the usual rotating wave approximation. The kinetic evolution operator, previously surmised, [M. de Haan. Physica, A171 (1991), 159] is here derived from first principles, justifying the usual practice in optics where the common use of the so-called pole approximation should no longer be viewed as an approximation but as an alternative description in the appropriate formalism. That model illustrates how some dressing of the atomic levels (and vertices), through an appropriate operator, finds its place naturally into the new formalism since the bare and dressed ground states do no longer coincide. Moreover, finite velocity for field propagation is now possible in all cases, without the presence of precursors for multiple detections.

G.B. Giorgini: Fashion, Florence and Diplomacy, 1950-55
Creators: name: Stanfill, Sonnet
Publisher: name: ZoneModa Journal
Year: 2021

description: Three key factors contributed Florence’s mid-century reign as Italy’s premier fashion city. Chief among them was the active championing of Florence by fashion impresario, Giovanni Battista Giorgini (1898–1971) whose bi-annual fashion shows associated Florence with high style and confirmed Italy’s reputation as a source for modish, high-quality clothing. Also crucial was the United States Government’s support of the Italian fashion industry; in diplomatic circles, encouraging a flourishing fashion sector was part of an American political strategy to deter communism in Italy. Members of the United States Foreign Service advocated on behalf of the Florence fashion events as part of a wider effort to reestablish Italy as an American economic and political ally. A third factor was the seductive beauty and historic charm of Florence, which Giorgini used strategically to entice guests to his shows and further his aims. These three elements combined to make Florence Italy’s one-time fashion capital, from Giorgini’s first show in 1951 until Milan took center stage in the 1970s.

description: Growth in the agricultural sector of the Soviet Union has been low and a constant cause of concern for the Soviet leadership. Western economists have long argued that the Soviet system lacks the efficiency in production that market forces provide in the West. This study finds little empirical evidence to support the argument of low levels of static allocative or technical efficiency in Soviet-type economies, compared with the West. Instead, the study shows that the slow pace of technological innovation is the main reason for slow Soviet growth.
Effects of an education program on radiation oncology patients and families
Creators: name: Hoff, Ann Cartledge
Publisher: name: American University

description: One hundred patients and family members in the radiation oncology department of the Carilion Cancer Center of Western Virginia participated in a study to test the effects of a new education/orientation program. We presented the information in verbal and written form. We measured the program's effect on anxiety, distress, compliance, use of support services, knowledge of radiation therapy, and satisfaction with care. There were no significant differences between the orientation and control groups in their level of anxiety and distress at the end of radiation treatment. There were also no significant differences between groups in the area of compliance. We found a few significant differences in knowledge of radiation therapy but no more than we would expect to find by chance given the number of analyses. We did find support for our hypotheses involving the utilization of support services. The orientation group was significantly more likely to use counseling services, meet with the dietitian, use the library, and seek outside support than the control group. Patients in the orientation group were significantly more satisfied with the care they received in the radiation oncology department than patients in the control group.

description: This report uses Granger's notion of causality to examine the relationship between the EC export subsidies and U.S. wheat export prices. The hypothesis that the EC's per unit export subsidy does not "cause" U.S., world, or EC export prices in the short run cannot be rejected, nor can the hypothesis be rejected that the U.S. or the world wheat price does not "cause" the per unit wheat subsidy. The results suggest a one-way causal relationship between EC exports and EC export price, but neither the export volume nor the per unit subsidy "cause" U.S. wheat export prices. The hypothesis that EC wheat exports are not caused by U.S. export prices is rejected, but causation is one directional without feedback; EC exports do not cause U.S. export prices. In determining the level of the monthly per unit subsidy granted, the EC responds to changes in the price of U.S. corn, but not to changes in the price of U.S. wheat, indicating that EC wheat competes with feed grains rather than U.S. wheat. The refund level also depends upon the ECU-U.S. dollar exchange rate. A 10-percent devaluation of the dollar relative to the ECU results in a 15-percent increase in the maximum wheat subsidy.

description: In this paper, we provide some equivalences on dentability in normed spaces. Among others we prove: the origin is a denting point of a pointed cone $C$ if and only if it is a point of continuity for such a cone and $\overline{C^*-C^*}=X^*$; $x$ is a denting point of a convex set $A$ if and only if $x$ is a point of continuity and a weakly strongly extreme point of $A$. We also analize how our results help us to shed some light on several open problems in the literature.

The Formation of the First Low-Mass Stars From Gas With Low Carbon and Oxygen Abundances

description: The first stars in the Universe are predicted to have been much more massive than the Sun. Gravitational condensation accompanied by cooling of the primordial gas due to molecular hydrogen, yields a minimum fragmentation scale of a few hundred solar masses. Numerical simulations indicate that once a gas clump acquires this mass, it undergoes a slow, quasi-hydrostatic contraction without further fragmentation. Here we show that as soon as the primordial gas - left over from the Big Bang - is enriched by supernovae to a carbon or oxygen abundance as small as ~0.01-0.1% of that found in the Sun, cooling by singly-ionized carbon or neutral oxygen can lead to the formation of low-mass stars. This mechanism naturally accommodates the discovery of solar mass stars with unusually low (10^{-5.3} of the solar value) iron abundance but with a high (10^{-1.3} solar) carbon abundance. The minimum stellar mass at early epochs is partially regulated by the temperature of the cosmic microwave background. The derived critical abundances can be used to identify those metal-poor stars in our Milky Way galaxy with elemental patterns imprinted by the first supernovae.

description: We place the first constraints on the obliquity of a planetary-mass companion (PMC) outside of the Solar System. Our target is the directly imaged system 2MASS J01225093-2439505 (2M0122), which consists of a 120 Myr 0.4 M_sun star hosting a 12-27 M_J companion at 50 AU. We constrain all three of the system's angular momentum vectors: how the companion spin axis, the stellar spin axis, and the orbit normal are inclined relative to our line of sight. To accomplish this, we measure projected rotation rates (vsini) for both the star and the companion using new near-infrared high-resolution spectra with NIRSPEC at Keck Observatory. We combine these with a new stellar photometric rotation period from TESS and a published companion rotation period from HST to obtain spin axis inclinations for both objects. We also fitted multiple epochs of astrometry, including a new observation with NIRC2/Keck, to measure 2M0122b's orbital inclination. The three line-of-sight inclinations place limits on the true de-projected companion obliquity and stellar obliquity. We find that while the stellar obliquity marginally prefers alignment, the companion obliquity tentatively favors misalignment. We evaluate possible origin scenarios. While collisions, secular spin-orbit resonances, and Kozai-Lidov oscillations are unlikely, formation by gravitational instability in a gravito-turbulent disk - the scenario favored for brown dwarf companions to stars - appears promising.

description: Exporting processed agricultural products rather than raw commodities benefits society much more than just the increased value of the commodities themselves. Processing adds to the value of the products and generates greater business activity, more jobs, higher personal income, and greater tax revenues. The issue of adding value to exports becomes even more relevant in view of the recently expanded use of subsidies to spur growth of raw grain and oilseed exports. Do such subsidies fully exploit the U.S. agricultural competitive advantage? Processing wheat worth $1 million would generate as much as $9 million in business activity, 109 full-time jobs, $1.9 million in personal income, $160,000 in Federal personal income taxes, and $199,000 in Federal corporate income taxes. Processing other commodities could yield even greater economic benefits. Trade barriers, foreign demand, and domestic capacity could prevent full realization of the potential economic benefits.
