A Novel Optical/digital Processing System for Pattern Recognition
This paper describes two processing algorithms that can be implemented optically: the Radon transform and angular correlation. These two algorithms can be combined in one optical processor to extract all the basic geometric and amplitude features from objects embedded in video imagery. We show that the internal amplitude structure of objects is recovered by the Radon transform, which is a well-known result, but, in addition, we show simulation results that calculate angular correlation, a simple but unique algorithm that extracts object boundaries from suitably threshold images from which length, width, area, aspect ratio, and orientation can be derived. In addition to circumventing scale and rotation distortions, these simulations indicate that the features derived from the angular correlation algorithm are relatively insensitive to tracking shifts and image noise. Some optical architecture concepts, including one based on micro-optical lenslet arrays, have been developed to implement these algorithms. Simulation test and evaluation using simple synthetic object data will be described, including results of a study that uses object boundaries (derivable from angular correlation) to classify simple objects using a neural network
A preliminary study on Dodecaceria pacifica (Fewkes)
In various areas along the coast in the vicinity of Monterey there are many colonies of the Polychaete worm Dodecaceria pacifica. An attempt has been made to find out something of the distribution, size, structure and the flora and fauna associated with these colonies

Land Subdivision, Heterogeneity, and Declining Food Security for African Pastoralists
Pastoral livestock inhabit landscapes that are spatially heterogeneous and have forage patches that pulse in their value to animals. Mobile pastoralists have evolved movement patterns to maximize use of these ephemeral food sources. In pastoral communities across Africa, changes in land tenure policy and socioeconomic pressures have caused pastoralists to decrease their mobility. Pastoralists recognize that shrinking access to land reduces their options to find forage, and theory suggests that the capacity of land to support herbivores decreases as a power of the square root of area accessible. We used ecosystem modelling in South Africa and Kenya to quantify declines in the number of livestock that can be supported under subdivision
Improving Employee Engagement: Making the Case for Planned Organizational Change Using the Burke-Litwin Model of Organizational Performance and Change
This case analysis focuses on a community college program environment, which is challenged by low employee participation and engagement. The purpose of this writing is to describe an assessment and proposal for planned changed in this program based on the Burke-Litwin Model of Organizational Performance and Change (Burke, 2002). The outcome of the assessment and plan for change is a theoretically based strategy applicable to this organization and suggested for consideration by other organizations where the presenting problem (low engagement in this case) is a symptom of deeper and underlying issues related to employee morale and organizational culture. This example is submitted to promote practitioner reflection in any organization challenged by low employee engagement, participation, or involvement. The depiction of the case describes the problem, a review of alternative organizational models to address it, the selection of an appropriate model, and the plan of action, which was proposed, consisting of initiatives to address the issues at specific points within the organization
Optimal Unemployment Insurance with Monitoring and Sanctions
This paper analyzes the design of optimal unemployment insurance in a search equilibrium framework where search effort among the unemployed is not perfectly observable.We examine to what extent the optimal policy involves monitoring of search effort and benefit sanctions if observed search is deemed insuficient.We find that introducing monitoring and sanctions represents a welfare improvement for reasonable estimates of monitoring costs; this conclusion holds both relative to a system featuring indefinite payments of benefits and a system with a time limit on unemployment benefit receipt.The optimal sanction rates implied by our calibrated model are much higher than the sanction rates typically observed in European labor markets.unemployment insurance;job search
A Study of The Food Habits Of 490 Students In A College Diving Hall
It is essential in group feeding, that principles of modern scientific management be applied with intelligence and discrimination to aid in the nations all out war effort. These principles should assure maximum utilization of available food supplies, improved quality of the products served and, most important, improved nutritional health and greater meal enjoyment for those who are served. Improved nutritional health can be a major factor in attaining optimum output and increase efficiency in everyday undertakings. The nation, as a whole, is emphasizing that healthful eating is an individual\u27s patriotic responsibility and for that reason, people have become nutrition consoious. Everyone may be aroused to his responsibility through education as well as through research.
Nutrition experts are the logical ones to provide the knowledge of nutrition needed to improve national food habits. Long time practice, however, is necessary to break old habits which may have been formed over a period of years. Fortunately, though, there are several approaches to this task, and one of them, if not begun before, maybe started at the college level. One of the foremost objectives of college education is learning how to live and learn. Good food practices should be included as essential in the successful completion of this objective. Nutrition may easily be taught through a program of education to a group of students eating in a college dining hall where the choices of food might easily he observed. Then,as students gain a knowledge of nutrition there should be evidence of changes in their selections of foods
