Assessing Program Effects Or Impact In Enterprise Development Programs, Tristi C. Nichols

Journal of Rural Social Sciences

Responding to questions increasingly posed by finders regarding what works best in assisting small businesses and what impacts are caused by program interventions, this paper aims to help program administrators answer these questions. Focusing on business development service provision, specific conceptual measures and quantitative variables are presented with examples in an effort to provide some guidance for collecting and analyzing data. The paper elucidates how program planners may emphasize the impact of their interventions, thereby explaining to finders what works best and how to prove it. It presents two major reflections about measures that yield robust results. The first conceptual …

Tidal Perturbations And Variability In Mesopause Region Over Fort Collins, Co(41n, 105w): Continuous Multi-Day Temperature And Wind Lidar Observations, C. Y. She, T. Li, R. L. Collins, Tao Yuan, B. P. Williams, T. Kawahara, J. D. Vance, P. Acott, D. A. Krueger, H. L. Liu, M. E. Hagan

An unusually long data set was acquired at the sodium lidar facility at Colorado State University (41N, 105W), between Sep 18 and Oct 01, 2003, including a 9-day continuous observation. This time is long enough to average out the perturbations of gravity waves and short-period planetary waves. As such, it can be used to define tidal-period perturbations in temperature and horizontal wind. Assuming the sodium mixing ratio is a constant of motion, the observed tidal-period oscillation in sodium density follows that of vertical wind. Thus, the data set defines tidal-period perturbations of temperature and wind vector. The observed amplitudes and …

University-Wide Entrepreneurship Education: Alternative Models And Current Trends, Deborah H. Streeter, John P. Jaquette Jr.

Journal of Rural Social Sciences

The paper examines the trend towards university-wide programs in entrepreneurship education. We present a conceptual framework for dividing university-wide programs into two categories: "magnet programs," which draw students into entrepreneurship courses offered in the business school, and "radiant programs," which feature entrepreneurship courses outside the business school, focused on the specific context of the nonbusiness students. Examining 38 ranked entrepreneurship programs, we found that about 79 percent now have university-wide programs, most of which follow a magnet model. In interviews with stakeholders at sample institutions, we found that magnet and radiant programs differ in terms of program definition, motivation for …

Entrepreneurship And Small Business Development As A Rural Development Strategy, Kenneth L. Robinson, Wylin Dassie, Ralph D. Christy

Journal of Rural Social Sciences

Many social scientists believe that supporting entrepreneurship development within low-income communities is a viable development strategy to combat poverty. Some even suggest that if economic development is to be effective, new businesses in low income areas must be started through local initiatives, and that entrepreneurship is critical to the maintenance of a healthy economy. Underpinned by recent scholarship and grassroots movements that suggest that presence of smaller scale, locally-controlled enterprises can help determine whether communities prosper or decline, this paper explores the links between entrepreneurship and rural development. Using a theory of change framework (Oldsman and Hallberg 2002), the authors …

Cetacean Brain Evolution: Multiplication Generates Complexity, Lori Marino

Anatomy Collection

Over the past 55-60 million years cetacean (dolphin, whale, and porpoise) brains have become hyperexpanded so that modern cetacean encephalization levels are second only to modern humans. At the same time, brain expansion proceeded along very different lines than in other large-brained mammals so that substantial differences between modern cetacean brains and other mammalian brains exist at every level of brain organization. Perhaps the most profound difference between cetacean and other mammalian brains is in the architecture of the neocortex. Cetaceans possess a unique underlying neocortical organizational scheme that is particularly intriguing in light of the fact that cetaceans exhibit …

Scaling A Dataflow Testing Methodology To The Multiparadigm World Of Commercial Spreadsheets, Marc Randall Fisher Ii, Gregg Rothermel, Tyler Creelan, Margaret Burnett

School of Computing: Technical Reports

Spreadsheet languages are widely used by end users to perform a broad range of important tasks. Evidence shows, however, that spreadsheets often contain faults. Thus, in prior work we presented a dataflow testing methodology for use with spreadsheets, that provides feedback about the coverage of cells in spreadsheets via visual devices. Studies have shown that this methodology, which we call WYSIWYT (What You See Is What You Test), can be used cost-effectively by end-user programmers. To date, however, the methodology has been investigated across a limited set of spreadsheet language features. Commercial spreadsheet environments are multiparadigm languages, utilizing features often …

The Effects Of Education Level On Physical Fitness Among Middle-Aged Adults In Taiwan, Shih-Wei Chou, Yin-Chou Lin, Chi-Te Li, Alice M. K. Wong

Rehabilitation Practice and Science

Health-related physical fitness can be assessed with four main attributes: body composition, muscular strength and endurance, flexibility, and cardiorespiratory endurance. Regular exercise is thought to improve physical fitness, and objective physical fitness assessment and appropriate exercise prescriptions may help unfit individuals to become fit. Assessment of physical fitness among the general population can aid the understanding of general levels of physical fitness in the community, promote healthy habits, and reduce the burden of chronic illness caused by physical inactivity. A total of 13,187 healthy adult Taiwanese citizens between 40 and 65 years of age were enrolled in this study between …

Effect Of Temperature On Type Of Cerebrovascular Accident, Sen-Yung Liu, Ta-Sen Wei, Cheng-Hsiung Hong

Rehabilitation Practice and Science

Monthly or seasonal change of climate has been suggested to associate with the incidence and type of stroke, but this association is not conclusive owing to variation in study design and geographic area. The aim of this study was to investigate the short-term effect of temperature variation on type of cerebrovascular accident in first-time stroke patients.There were 1008 in-patients enrolled in this study, including 718 ischemic (infarct) stroke and 290 hemorrhagic stroke patients. The age was 68.9±11.0 years in the infarct and 62.9±13.6 years in the hemorrhagic group; 62%(181 cases) of the infarct group and 55%(395 cases) of the hemorrhagic …

Automated Evaluation Of Radiodensities In A Digitized Mammogram Database Using Local Contrast Estimation, Min Taek Kim

Theses and Dissertations

Mammographic radiodensity is one of the strongest risk factors for developing breast cancer and there exists an urgent need to develop automated methods for predicting this marker. Previous attempts for automatically identifying and quantifying radiodense tissue in digitized mammograms have fallen short of the ideal. Many algorithms require significant heuristic parameters to be evaluated and set for predicting radiodensity. Many others have not demonstrated the efficacy of their techniques with a sufficient large and diverse patient database. This thesis has attempted to address both of these drawbacks in previous work. Novel automated digital image processing algorithms are proposed that have …

Vlsi Implementation Of An Efficient Method For The Computation Of Line Spectral Frequencies, David L. Reynolds

Theses and Dissertations

In speech coding applications using linear predictive techniques, the computation of line spectral frequencies (LSFs) from the predictor coefficients is an extremely computationally intensive task. The unique properties of the symmetric and antisymmetric polynomial roots limit the region which must be searched, however it is still necessary to perform a root-finding algorithm on a high-order polynomial.

Certain algorithms have been developed to reduce the complexity of the root finding exercise. One such algorithm, developed by Ramachandran and Kabal, takes advantage of certain properties of the symmetric and antisymmetric polynomials to map the upper portion of the unit circle onto the …

Three-Dimensional Shape Characterization For Particle Aggregates Using Multiple Projective Representations, Jonathan Paul Corriveau

Theses and Dissertations

Shape descriptors are used extensively in computer vision/automated recognition applications such as fingerprint matching, robotics, character recognition, etc. The conventional two-dimensional shape descriptors used in these applications do not readily lend themselves to compact representations in three dimensions. The situation is even more challenging when one attempts to numerically describe the three-dimensional shapes of a mixture of objects such as in an aggregate mix.

The goal of this study is the design, development and validation of automated image processing algorithms that can estimate three-dimensional shape-descriptors for particle aggregates. The thesis demonstrates that a single set of numbers representing a composite …

Short-Term Scheduling Of A Hydro-Thermal System Using Linear Programming Technique, A Kyaruzi

Tanzania Journal of Engineering and Technology (TJET)

The paper discusses the short term scheduling of Hydrothermal for Tanzania Electricity Supply Company (TANESCO) Power System. The problem is to determine on hourly interval the Hydro and Thermal generation. The scheduling keeps balance between production and consumption in a reliable and economical way during the study period. Linear programming (LP) mathematical model using MATL4B has been developed. The constraints are hydrological balance, thermal power plants limitations and load requirements. The result from LP solution gave low operation cost. Generation was mainly from hydro and all reservoirs elevation was high at the end ofplanning period.

Acute Simultaneous Multiple Infarctions In One Cerebral Hemisphere: A Casereport, Ting-I Han, Mu-Jung Kao, Der-Yang Chou, Pey-Yu Yang

Rehabilitation Practice and Science

Acute ischemic stroke is well known to be a single event. However, multiple simultaneous acute strokes involving more than one vascular territory are less studied. Large-artery disease of corresponding vessels and cardioembolism are thought to be the most important risk factors for multiple simultaneous infarctions. Diffusion-weighted imaging (DWI), which successfully discriminats acute from chronic infarct, is particularly useful in patients with multiple infarcts in more than one territory. The most common combinations of simultaneous multiple infarction in one cerebral hemisphere involve the territories of the anterior superficial middle cerebral artery (MCA) plus the posterior superficial MCA, and the territories of …

Trauma-Related Vertebral Artery Dissection With Delayed Onset Cerebellar Infarction: A Casereport, Tsung-Ying Li, Liang-Cheng Chen, Shuu-Hai Jiang, Shiou-Ping Lin, Kao-Chung Tsai

Rehabilitation Practice and Science

Cerebellar stroke is uncommon in young patients. We report the case of a 22-year-old man with a delayed cerebellar infarction secondary to vertebral artery dissection caused by trauma. While riding a bicycle as part of an extreme sport, his left clavicle struck a bicycle handle. Evaluation in the emergency room led to a diagnosis of left shoulder contusion without fracture of clavicle or cervical spine. Headache, severe vomiting, and weakness of the right-sided limbs developed three days later, and he presented to emergency staff again. Head injury was initially suspected, but the diagnosis was left vertebral artery dissection with delayed-onset …

Theoretical Modeling Of Protective Oxide Layer Growth In Non-Isothermal Lead-Alloys Coolant Systems, Yitung Chen

Transmutation Sciences Materials (TRP)

The goal of the proposed research project is to provide basic understanding of the protective oxide layer behaviors and to develop oxide layer growth models of steels in non-isothermal lead-alloys (lead or lead-bismuth eutectic) coolant systems. It is widely recognized that the corrosiveness of the lead-alloys is a critical obstacle and challenge for which it can be safely used or applied in the nuclear coolant systems. Active oxygen control technique can promote the formation of the “self-healing” oxide films on the structural material surface, drastically reducing steel corrosion and coolant contamination. Many experiments of steels exposed to flowing lead-alloys have …

Evaluation Of Fluorapatite As A Waste-Form Material: First Quarter Report (2004-05), October 1 - December 31, 2004, Dennis W. Lindle, Oliver Hemmers

Separations Campaign (TRP)

Fluorapatite, fluorinated calcium phosphate, has been identified as a potential matrix for the entombment of the zirconium fluoride fission product waste stream from the proposed FLEX process. If the efficacy of fluorapatite-based waste-storage can be demonstrated, then new and potentially more-efficient options for handling and separating high-level wastes, based on fluoride-salt extraction, will become feasible. This proposal will develop a dual-path research project to develop a process to fabricate a synthetic fluorapatite waste form for the ZrF₄, FP waste stream, characterize the waste form, examine its performance under environmental conditions, and correlate the behavior of the waste form …

Thickening Of Finger Extensor Tendons In Hemiplegic Hands Of Stroke Patients, Nai-Hsin Meng, Sui-Foon Lo, Ting-I Han, Yi-Fang Hu, I-Shien Tseng, Mu-Jung Kao

Rehabilitation Practice and Science

Thickening of finger extensor tendons in hemiplegic hands of stroke patients has never been reported. We reported 11 patients with stroke who experienced gradual onset of a painless swelling at the dorsal aspect of the hemiplegic wrist. Soft tissue sonography revealed that the swellings were mainly composed of thickened finger extensor tendons. This thickening typically involved the tendons of the 4th dorsal extensor compartment between the proximal carpal and mid-metacarpal levels. The maximal thickness of these tendons could reach over three times that of the corresponding tendons of the contralateral hand. The synovial tissue surrounding the thickened tendon was also …

Primary Adrenal Insufficiency Developing After Traumatic Brain Injury: A Casereport, June-Kai Chen, Tien-Wen Chen, Ming-Cheng Weng, Mao-Hsiung Huang

Rehabilitation Practice and Science

There have been isolated reports in the literature of the natural history and less than complete knowledge of the epidemiology and the pathophysiology of endocrine alteration occurring after traumatic brain injury (TBI). This article describes one primarily adrenal-dysfunction patient with severe TBI who had no evidence of present or prior adrenal autoimmune disease, infection, hemorrhage, or malignancy. It is suggested that this distinct condition can be labeled as ”primary adrenal insufficiency (PAI) developing after TBI”.

Metatarsal Stress Fracture: A Casereport, Chwan-Chin Leu, Chorng-Song Chou, Chin-Teng Chung, Chun-Fu Wang

Rehabilitation Practice and Science

A stress fracture is defined as a partial or complete fracture of bone due to the inability to withstand non-violent stress applied in a rhythmic, repeated, subthreshold manner. It could occur in any kind of sport. However, it usually occurs in running-based sports and running or jogging. Initial diagnosis of stress fracture is difficult. A careful study of the patient's history amd physical examination combined with appropriate radiographic examination, or if indicated, scintigraphy, provides a highly accurate diagnosis.A 19-year-old male athlete suffered from insidious onset of pain in the right forefoot after judo training. This focal pain eventually precluded any …

An Investigation Of Multi-Dimensional Evolutionary Algorithms For Virtual Reality Scenario Development, Scott Papson

Theses and Dissertations

Virtual reality (VR) has emerged as a powerful visualization tool for design, simulation, and analysis in modem complex industrial systems. The primary motivation for this thesis is to develop a framework for the effective use of VR in design-simulation-analysis cycles, particularly in situations involving large, complex, multi-dimensional data-sets. This thesis develops a framework that is intended to support not only the integration of such data for visual, interactive, and immersive displays, but also provides a method for performing risk analysis. Previously "static" VR environments are enhanced with time-evolutionary capabilities. Four candidate algorithms are evaluated for this purpose – deterministic modeling, …

Heterogeneous Multi-Sensor Data Fusion Using Geometric Transformations And Parzen Windows For The Nondestructive Evaluation Of Gas Transmission Pipelines, Joseph Anthony Oagaro

Theses and Dissertations

The natural gas transmission pipeline network in the United States is a key component of the nation's energy supply infrastructure and extends for over 280,000 miles and has an average age of over 60 years. The integrity of the pipeline is maintained by periodic inline inspections using magnetic or ultrasonic pigs. Defect characterization algorithms developed using current pigging data are hampered by the fact that single inspection techniques (either magnetic or ultrasonic) do not yield sufficient information for accurately and repeatably characterizing defects. This thesis demonstrates that defect characterization algorithms using multiple inspection techniques can accomplish this task. In particular, …
