Cartels in an Nth-Best World: The Wholesale Foodstuff Trade in Ibadan, Nigeria

The purpose of this paper is to develop an understanding of the economic functions and associated welfare implications of the cooperative associations that dominate the wholesale trade in two staple foods. Questionnaire responses lead to several conclusions. Individual traders face incomplete markets, imperfect information, and little government-provided institutional and physical infrastructure. The associations are sophisticated Coase-like responses to this market environment: they focus on reducing their members\u27 transaction costs, and hence the marginal private costs of trading. Thus it is likely that these associations enhance efficiency. We conclude with a critique of current government policy with respect to this trade

Confianza metacognitiva: una aproximación desde la neurociencia

This is an Accepted Manuscript of an article published by Taylor & Francis Group in [JOURNAL TITLE] on [date of publication], available online at:http://www.tandfonline.com/[Article DOI].Metacognition refers to thinking about our own thinking and implies a distinction between primary and secondary cognition. This article reviews how neuroscience has dealt with this distinction between first and second-order cognition, with special focus on meta-cognitive confidence. Meta-cognitive confidence is important because it affects whether people use their primary cognitions in guiding judgments and behaviors. The research described in this review is organized around the type of primary thoughts for which people have confidence, including judgments about memory, choices, and evaluative judgments. Along with other areas, prefrontal cortex and parietal regions have been consistently associated with judgments of meta-cognitive confidence in these three domains. Although metacognitive confidence might be associated with particular brain activity in most of the studies reviewed, confidence often seems to be confounded with other potentially important dimensions, such as effort and ease. Given that people tend to be less certain in tasks that are more difficult, more research is needed to examine the brain activity specifically linked to confidence.La meta cognición se refiere a lo que pensamos sobre nuestros propios pensamientos e implica la distinción entre cognición primaria y secundaria. El presente artículo describe como la neurociencia ha examinado esta distinción entre cognición de primer y segundo orden, presentado especial atención al concepto de confianza metacognitiva. Este tipo de confianza es importante ya que determina en qué medida las personas usamos los pensamientos a la hora de guiar nuestros juicios y acciones. La investigación descrita en este trabajo se organiza a través del tipo de cognición primaria sobre la que se tiene confianza o duda, incluyendo juicios sobre nuestra memoria y también sobre nuestras evaluaciones y decisiones. En la mayoría de estudios, las áreas de la corteza prefrontal y parietal aparecen vinculadas con los juicios de confianza en estos tres dominios. A pesar de la asociación observada entre la confianza metacognitiva y algunas zonas concretas de actividad cerebral, el presente trabajo precisa que la confianza a menudo se confunde con otros aspectos como la facilidad y el esfuerzo. En la medida en que se suele estar menos seguro de los juicios de tareas difíciles, se hace necesario llevar a cabo investigaciones en las que se especifique con mayor precisión la actividad cerebral vinculada con la confianza

Dynamics of Bulk vs. Nanoscale WS_2: Local Strain and Charging Effects

We measured the infrared vibrational properties of bulk and nanoparticle WS$_2$ in order to investigate the structure-property relations in these novel materials. In addition to the symmetry-breaking effects of local strain, nanoparticle curvature modifies the local charging environment of the bulk material. Performing a charge analysis on the \emph{xy}-polarized E$_{1u}$ vibrational mode, we find an approximate 1.5:1 intralayer charge difference between the layered 2H material and inorganic fullerene-like (IF) nanoparticles. This effective charge difference may impact the solid-state lubrication properties of nanoscale metal dichalcogenides.Comment: 6 pages, 5 figure

Mycoplasmal conjunctivitis in wild songbirds: the spread of a new contagious disease in a mobile host population.

A new mycoplasmal conjunctivitis was first reported in wild house finches (Carpodacus mexicanus) in early 1994. The causative agent was identified as Mycoplasma gallisepticum (MG), a nonzoonotic pathogen of poultry that had not been associated with disease in wild songbirds. Since the initial observations of affected house finches in the mid-Atlantic region, the disease has become widespread and has been reported throughout the eastern United States and Canada. By late 1995, mycoplasmal conjunctivitis had spread to an additional species, the American goldfinch (Carduelis tristis). This new disease exemplifies the rapid spread of a pathogen following introduction into a mobile wildlife population and provides lessons that may apply to emerging human diseases

Autonomous Tennis Ball Collector

Practicing tennis often involves hitting many tennis balls from one side of the court to the other without an opponent to hit the balls back. In training sessions like these, the task of collecting the balls is laborious when performed manually. The objective of this project is to develop a robotic tennis ball collector that can automatically collect the balls from one side of the court so that the player can rest rather than collect the balls manually. This document outlines the process of designing such a robot. Included in this report is background research, prototype, and concept modeling, along with a finalized design, and a complete timeline of our process. We will also detail the manufacturing process and the design verification. In the conclusion we will provide you with recommendations for future projects. Throughout our research, we discovered many similar products, but none met all of the customer’s requirements, thus opening a window for our product. After copious design consideration, we selected the strongest idea that satisfied our customers’ needs and are moving forward with structural modeling and preliminary analysis on it. After the structural prototype revealed issues in the design we went back to work and finalized a design that we felt confident with and still satisfied all the requirements. As seen in this report the final design utilizes structural framing materials to build the robot and allows for ease of attachment for all the electrical components. The final step in the design process was to test the verification prototype to ensure that it met all our specifications. Unfortunately, our design did not pass as many of the tests as we would have liked, and this is detailed in that section. While at the conclusion of this project, we did not complete as much as we hoped, there is a good foundation in place for the project to continue as our sponsor so desires

Distributed venting in the ~200 × 200‐m hydrothermal field creates a plume with vertical velocities of ~10 cm/s in the mid‐water column. Salinity profiles indicate that during the period of strong summer stratification the plume rises to a neutral buoyancy horizon at ~45‐m depth, corresponding to a ~70‐m rise height, where it generates an anomaly of ~5% (−0.0014 psu) relative to background lake water. We simulate the plume with a numerical model and find that a heat flux of 28 MW reproduces the salinity and vertical velocity observations, corresponding to a mass flux of 1.4 × 103 kg/s. When observational uncertainties are considered, the heat flux could range between 20 to 50 MW.The authors thank Yellowstone National Park Fisheries and Aquatic Sciences, The Global Foundation for Ocean Exploration, and Paul Fucile for logistical support.
