Abstract:

We consider a brokered market with heterogeneous suppliers and consumers of identical items or services. Each supplier determines a minimum acceptable price for the items it supplies, based on its costs and target rate of return. The broker begins with a fixed set of items from the suppliers. Customers arrive periodically to the market and offer a bid for an item. If a customer wants more than one item, a set of bids is made. If the broker accepts a bid it must be assigned an item with minimum accceptable price less than or equal to the bid, and the price paid is the bid price. The broker has the option of rejecting a bid. The broker makes acceptance and assignment decisions to maximize the total expected discounted revenue. We show the optimal policy has a simple threshold structure where thresholds can be easily determined by finding the individually optimal policies subject to priorities.

Abstract:

The research study aimed to trace the BSCA graduates of JBLFMU-Molo and know their level of satisfaction. The descriptive survey research design was employed in the study. The participants were the 64 conveniently selected BSCA graduates in the years 2009, 2010, 2011, 2012 and 2013. The data used were responses from the graduates with the use of the alumni tracer questionnaire. Descriptive statistics used were mean, frequency count and content analysis. Inferential statistics included a t-test for independent samples and One-Way ANOVA set at .05 alpha. Results revealed that the graduates had a “high” employment rate. The level of satisfaction of the graduates was also found to be “moderate”. When classified according to employment status, broker licensure status and year graduated, there was no significant difference existed among their level of satisfaction.

Abstract:

Purpose – To analyze the cases and sanctions FINRA reported in 2014 and prior years to evaluate what issues may be important for broker-dealers and their representatives in the future. Design/methodology/approach – This article discusses the overall statistics for cases reported by FINRA in 2014 and then focuses on the top enforcement issues for FINRA and some of the key cases. All of this analysis includes a comparison to enforcement statistics from prior years to help identify potential trends. Findings – This article concludes that 2014 was a blockbuster year for FINRA as the fines imposed by the regulator increased by 125 per cent. This article also finds that while FINRA is still focusing on many of the same issues as before, including advertising and trade reporting, other issues, such as anti-money laundering, received a significant spike in attention in 2014. Originality/value – This article contains valuable information about recent FINRA enforcement activity and practical guidance from experienced securities lawyers.

Abstract:

This study determines the extent to which middle, senior and top managers fulfill their managerial roles (mentor, facilitator, monitor, coordinator, director, producer, broker, and innovator). It also evaluates their focus (internal versus external) and preference for structure (stability and control versus flexibility and change) as well as whether their orientations are aligned towards the same vision/goal. A sample of 202 managers (middle, senior, top) was drawn using a stratified random sampling technique. Data was collected using a questionnaire and analyzed using descriptive and inferential statistics. The results of the study emphasize the importance of aligning the organizational focus and preference for structure with the organizational vision/goal and ensuring that the managerial cadre is appropriately developed in the competencies needed to attain the vision/goal.

Abstract:

This study was analyzed value chain analysis of sesame in Bench Maji Zone of Southwestern, Ethiopia. It was specifically aimed to address the research gaps by, identifying the major value chain actors and mapping the value chain, and identifying major factors affecting market outlet choices of sesame producers in Meinit Goldya and Guraferda Districts. For addressing these objectives the study used both primary and secondary data obtained from field survey and desk review. Multistage random sampling technique was used to draw 270 sesame producers. Descriptive statistics and econometric method of data analysis were used to analyze the data. The major value chain actors for sesame marketing in the districts were producers, wholesalers, rural collector, cooperatives, broker/commission agents, retailers, local consumers, ECX, exporters and non-governmental organizations. The multivariate probit model results indicated that Years of experiences, Coop membership, household size, Education level, Land under sesame, Quantity supply, participating in training and distance to nearest market significantly influenced sesame producer’s choice of market outlet. Depending on results of this study recommend that strengthening farmers sesame cooperative and enhancing the financial capacity of cooperative, improving accessibility of Transport services and developing infrastructure, improving farmers’ knowledge through adult education as well as their experience sharing with other sesame producing farmers, improving productivity through strengthening supportive institutions(extension service provider) motivating sesame producing farm household to participate different training. Therefore, those important socioeconomic and institutional factors which are mentioned above must take into account to improve the productivity of sesame in the study area.

Abstract:

The purpose of this paper aims to get empirical evidence about the performance of Technical analysis considering profitability when coupled on a stand-alone system to trigger orders of buy/selling shares via home broker at Bovespa, also present a modified methodology for the Lorenzoni et al. (2007) test to check the presence of informational content in technical analysis. This autonomous system consists of a modified routine of rational choice constant in Arrow (1959) which seeks maximum profit trying to simulate human behavior as a strategy for triggering orders. It was tested 352 different combinations of possible orders when attached to the rational behavior for each series tested. The data used were companies listed in FGV-100 index (theoretical portfolio of the year 2009) and Ibovespa (theoretical portfolio of Sept/Dez 2009) with a total of 129 companies from 3/01/2000 to 09/30/2009. The main results show that the best results were obtained by moving average followed by Bollinger bands and, finally the histogram, which has not proved by self efficient. Orders were counted in quantities. It was found rational choice behaviors of buy/sell with superior performance to its peers when compared in terms of profitability with the returns obtained by Ibovespa. The statistics of White (2000) and the modified test of Lorenzoni et al. (2007), proposed by the author, had suggested the presence of informational content for the majority of the series tested in the sample when the graphs indicated long position for both the original data and for the recreated data from the AR(1)-GARCH(1,1) model.

Abstract:

The existence of degenerated quantum vacua (coherent states of zero modes), for N-level quantum systems, leads to a breakdown of the original unitary U (N) symmetry in the many-particle theory. The action of some spontaneously broken symmetry transformations destabilize these pseudo-vacua and make them radiate. We study the structure of this thermal radiation, which turns out to be of Fermi–Dirac type.

Abstract:

Abstract Cellular statistical models are designed to provide a simple two-parameter characterization of the structure of broken cloud fields described through distributions of cloud fraction and of chord lengths for clouds and clear gaps. In these analytical models cloud fields are assumed to occur on a semiregular grid of cells (which can be vaguely interpreted as atmospheric convective cells). In a simple, discrete cell model, cell size is fixed and each cell can either be completely filled with cloud with some probability or remain empty. Extending the discrete model to a continuous case provides more realism by allowing arbitrary cloud and gap sizes. Here the continuous cellular model is tested by comparing its statistics with those from large-eddy simulations (LES) of marine boundary layer clouds based on case studies from three trade-cumulus field projects. The statistics largely agree with some differences in small sizes approaching the LES model grid spacing. Exponential chord-length distributions follow from the assumption that the probability of any cell being cloudy is constant, appropriate for a given meteorological state (narrow sampling). Relaxing that assumption, and instead allowing this probability to have its own distribution, leads to a power-law distribution of chord lengths, appropriate to a broader sample of meteorological states (diverse sampling).

Abstract:

We review aspects of broken symmetry and the nature of long range order in theories of anyons starting with bosons with a statistical interaction. We introduce a novel gauge invariant quantization scheme that allows the identification of local and gauge invariant order parameters. The connection between spin and statistics is reviewed and the consequences of broken symmetries in the anyon representation are discussed. An anyon gas is studied in the Bogoliubov approximation, it is determined that the ground state is a condensate of charge-flux composites with “quasi-long-range order” at zero temperature, a “weak” gap in the spectrum and finite helicity modulus. The system is disordered at nonzero temperatures. The disorder is not caused by Goldstone bosons but by the strong infrared behavior arising from the Coulomb interaction induced by the long-range statistical interaction. The properties of topological vortices in nonrelativistic and in relativistic Landau-Ginzburg theories are studied in detail. We study the physics of the mean-field ansatz and quasi-long range order in a simple exactly soluble relativistic model. This model exhibits a novel phenomenon of charge redistribution to the boundaries and restoration of translational invariance in the infinite volume limit. It also illuminates the physics of quasi-long-range order with a gap in the spectrum, statistical charge polarization by external magnetic fields and the role of “large” gauge transformations.

Abstract:

OBJECTIVES/SPECIFIC AIMS: Community health coalitions (CHC) aim to improve local cultures of health, health behaviors, and health outcomes. However, challenges sustaining partnerships and activities limit CHC impact. Traditional CHC evaluations survey members about perceived effectiveness, failing to capture underlying network structures and community health outcomes. Thus, we applied a mixed-methods evaluation in eight rural Indiana CHC, triangulating social network analysis [(SNA), conducted in 2017], functioning effectiveness [Coalition Self-Assessment Survey (CSAS), also 2017], and latest county health statistics (2015–2016) to assess existing CHC building efforts, inform best practices, and facilitate the adoption of evidence-based programming. METHODS/STUDY POPULATION: Across the eight rural Indiana CHC, relationships between the three evaluation components were analyzed using Pearson’s correlations. We are now collaborating with Purdue’s Nutrition Education Program Community Wellness Coordinators to scale up evaluation efforts throughout Indiana. RESULTS/ANTICIPATED RESULTS: CHC effectiveness was positively correlated with the average number of connections CHC members held in the network (mean indegree) and negatively correlated with the presence of a network broker (eigenvector centrality). However, effective leadership was positively correlated with opioid deaths and treatment, food insecurity, smoking during pregnancy, lack of healthcare coverage, and fair/ poor health status, and negatively correlated with prenatal care. Effective operating norms was positively correlated with smoking during pregnancy and preterm births, and negatively correlated with prenatal care. Effective action outcomes was positively correlated with opioid deaths and treatments, smoking during pregnancy, preterm births, and fair/ poor health status, and negatively correlated with respondents reporting they had no personal doctor. DISCUSSION/SIGNIFICANCE OF IMPACT: Interestingly, CHC effectiveness was positively correlated with poor county health outcomes related to infant well-being. Thus, CHC may develop in counties with a high unmet need for effective pregnancy and infant services. Alternatively, the prevalent CHC focus on obesity prevention may eclipse programmatic efforts to improve infant well-being. Longitudinal evaluations and scaling up evaluation efforts across Indiana are being pursued to clarify trajectories and inform best practices, which in turn should provide recommendations for network structures to improve CHC effectiveness and county health.

Abstract:

e18317 Background: The National Cancer Institute (NCI) Surveillance, Epidemiology, and End Results (SEER) Program curates population-based cancer data representing 34% of the US population. CancerLinQ is an ASCO initiative that collects and analyzes electronic health record (EHR) data to give oncologists opportunities to improve the quality of patient care. With the shared goal of understanding care delivery, NCI SEER and CancerLinQ launched a pilot linkage. Purpose: Establish data exchange between registries and oncology practices to a) provide clinicians with SEER data to more effectively evaluate care within their practices, and b) enhance ability of SEER registries to capture cancer-related data and facilitate compliance of legally mandated public health reporting requirements while supporting metrics for quality reporting to providers. Methods: The SEER Iowa Cancer Registry is developing bidirectional linkages with CancerLinQ practices. The initial pilot in Iowa establishes connectivity and a data pipeline to capture discrete data elements in EHRs. The linkage methods are securely conducted by IMS, an honest broker for the Registry and ASCO. Patterns of care will be evaluated in the matched patient population. Analysis of shared data elements will provide comparative validation of data captured electronically (EHR) and manually (abstraction). Enhancing the patient care quality through efficient utilization of shared data was paramount when selecting treatment-related Quality Oncology Practice Initiative (QOPI) measures for calculation focusing on breast (QPP 449, QPP 450) and prostate cancer (QPP 102, QPP 104). Results: Publicly available SEER data for cohort evaluation is available to providers via SEERLinQ. The two-way exchange data pipeline complies with reporting requirements. Validation of shared data elements, statistics for matched patients, improved data completeness measures, and automated calculation of QOPI measures will be demonstrated. Conclusions: This collaboration builds an initial foundation of curated Registry-EHR linked data to automate cancer reporting to lower the physician burden, improve SEER evaluation of clinical care patterns, and enhance patient care quality.

Abstract:

Abstract A new analytical statistical model describing the structure of broken cloud fields is presented. It depends on two parameters (cell size and occupancy probability) and provides chord distributions of clouds and gaps between them by length, as well as the cloud fraction distribution. This approach is based on the assumption that the structure of a cloud field is determined by a semiregular grid of cells (an abstraction of the atmospheric convective cells), which are filled with cloud with some probability. First, a simple discrete model is introduced, where clouds and gaps can occupy an integer number of cells, and then a continuous analog is developed, allowing for arbitrary cloud and gap sizes. The influence of a finite sample size on the retrieved statistics is also described.

Abstract:

Abstract In the third part of the “Cellular Statistical Models of Broken Cloud Fields” series the cloud statistics formalism developed in the first two parts is interpreted in terms of the theory of Markov processes. The master matrix introduced in this study is a unifying generalization of both the cloud fraction probability distribution function (PDF) and the Markovian transition probability matrix. To illustrate the new concept, the master matrix is used for computation of the moments of the cloud fraction PDF—in particular, the variance—which until now has not been analytically derived in the framework of the authors’ previous work. This paper also serves as a bridge to the proposed future studies of the effects of sampling and averaging on satellite-based cloud masks.

Abstract:

Crime is costly, yet we understand little about it. The United States justice system costs $280 billion per year, but compared to other areas, such as medicine and agriculture, we have few answers for the field's fundamental questions, like what causes crime and how we can best use our justice system to respond to it. In addition, the success or failure of the justice system impacts our safety, freedoms, and trust in government. Criminologists are working to bridge this gap in knowledge using methods that are fundamentally statistical, including randomized designs, case-control studies, instrumental variables, and natural experiments. This review discusses how criminologists explore the police, courts, sentencing, and communities and their effect on crime using daylight saving time, natural disasters, coding errors, quirks in funding formulas, and other phenomena to simulate randomization. I include analyses of racial bias, police shootings, public defense, parolees, graffiti, vacant lots, and abandoned buildings. This review should encourage statisticians to bring their methods and expertise to bear on criminological questions, as the field needs broader and deeper scientific examination.

Abstract:

We study the inequivalent quantizations of (1 + 1)-dimensional nonlinear sigma models with space manifold S1 and target manifold X. If X is multiply connected, these models possess topological solitons. After providing a definition of "spin" and "statistics" for these solitons and demonstrating a spin-statistics correlation, we give various exmples where the solitons can have exotic statistics. In some of these models, the solitons may obey a generalized version of fractional statistics called ambistatistics. The relevance of these 2D models to the statistics of vortices in (2 + 1)-dimensional spontaneously broken gauge theories is also discussed. We close with a discussion concerning the extension of our results to higher dimensions.

The curves characteristics for the weight percent of the broken debris with the mesh size distribution were obtained through the screening statistics. Furthermore, the fractal dimension of the specimen broken debris was derived through theoretical calculations and statistical analysis. The results showed that the rock cutting fragmentation is of significant fractal features under the mechanical shock loads. The broken debris fractal dimension of the structural integrity specimens is bigger, the range of the fractal dimension is smaller and the broken debris size distribution is more even than that of the poor structural integrity specimens. The fractal dimension is the ideal test indicator to assess and analysis the rock-breaking degree.

Abstract:

It is believed that non-Gaussian statistics of intermittency leads to anomalous scaling in turbulence, and self-similarity normal scaling corresponds to Gaussian assumptions. By a reasonable model of probability density function (PDF) of intermittent velocity increment, we demonstrate the possibility that non-Gaussian statistics may lead to self-similarity and normal scaling. The experimental facts of scaling-range exponents being anomalous, are not against a non-Gaussian self-similarity in the inertial range. In scaling ranges at experimental Reynolds numbers, viscous and large-scale effects are not negligible, the non-Gaussian self-similarity is broken due to viscous and large-scale effects, and anomalous scaling is observed.

Abstract:

Measurements of ionizing and nonionizing particles are performed during the rupture tests of steel rods having different diameter. A ZnS ( Ag ) alpha detector, a Geiger counter and a 3 He proportional counter for neutrons are used. From the distributions of the recorded intensity maxima, different particles emissions are suggested to occur in broken and nonbroken samples. A hint for the emission of neutrons at rupture is also obtained. Such neutron emissions are predicted in the framework of the piezonuclear theory.

Abstract:

Teachers’ attitudes towards statistics can have a significant effect on their own statistical training, their teaching of statistics, and the future attitudes of their students. The influence of attitudes in teaching statistics in different contexts was previously studied in the work of Estrada et al. (2004, 2010a, 2010b) and Martins et al. (2011). This work is part of a broader study of Portuguese education teachers and statistics. In the current paper, we use a qualitative content analysis of survey responses from Portuguese first-stage in-service teachers, focusing on nine open-ended items extracted from the Escala de Actitudes hacia la Estadística de Estrada (Estrada, 2002). These responses allow us to investigate teachers’ attitudes towards statistics, and their reasons and motivations for holding these attitudes.

Abstract:

Abstract A simple and fast algorithm for generating two correlated stochastic two-dimensional (2D) cloud fields is described. The algorithm is illustrated with two broken cumulus cloud fields: cloud optical depth and cloud-top height retrieved from the Moderate Resolution Imaging Spectroradiometer (MODIS). Only two 2D fields are required as an input. The algorithm output is statistical realizations of these two fields with approximately the same correlation and joint distribution functions as the original ones. The major assumption of the algorithm is statistical isotropy of the fields. In contrast to fractals and the Fourier filtering methods frequently used for stochastic cloud modeling, the proposed method is based on spectral models of homogeneous random fields. To retain the same probability density function as the (first) original field, the method of inverse distribution function is used. When the spatial distribution of the first field has been generated, a realization of the correlated second field is simulated using a conditional distribution matrix. This paper serves as a theoretical justification of the publicly available software “Simulation of a two-component cloud field,” which has been recently released. Although 2D rather than full 3D, the stochastic realizations of two correlated cloud fields that mimic statistics of given fields have proven to be very useful to study 3D radiative transfer features of broken cumulus clouds for a better understanding of shortwave radiation and the interpretation of remote sensing retrievals.
