Selected perceptions of aspects of sex equity and affirmative action within Iowa community colleges

This research project was undertaken in order to study selected perceptions of issues related to sex equity and affirmative action within chosen Iowa merged area community colleges. The four major objectives of this research project were to determine the extent of knowledge of the adoption of institutional policies relating to state-mandated affirmative action, to determine the extent of knowledge of the implementation of state-mandated policies relating to affirmative action, to determine if there is a need for policy implementation on the part of community colleges, and to determine if the Iowa Department of Education should continue to promote affirmative action policy and sex equity. To achieve the major objectives, the perceptions of nonadministrative employees were assessed and evaluated as they relate to the State of Iowa mandated affirmative action objectives;A total of 176 faculty and professional student service staff responded to mailed surveys (a response rate of 73.3%). Of this total, 90 (51.1 percent) surveys were received from male respondents and 86 (48.9 percent) surveys were received from female respondents. The purpose of the surveys were to assess current affirmative action activities within community colleges and to assess perceived policies their institutions may have incorporated and/or actions they believe are presently being carried out that affect sex equity. To achieve the stated objectives of this study, mandated State of Iowa affirmative action guidelines within merged area community colleges were measured by faculty and professional student service staff through their perceptions of their college\u27s policies/actions. Survey respondents were subgrouped according to gender, professional position, and urban or rural setting of their respective college. In addition, years of professional experience in the community college setting and years of formal education were controlled factors;Differences in perception of affirmative action among the subgroups were determined through ANOVA with covariance. Statistically significant F value differences were observed at the.05 level;Statistically significant differences of perception were determined for the variable of demographic setting. The variables of gender and professional position did not produce statistical significance. The findings also reported that the factors of years of community college experience and years of formal education did not affect perceptions in relation to the stated variables;From the findings there was agreement of perception that the surveyed community colleges were following state-mandated affirmative action procedures. However, the documented perceptions indicated inconsistencies in awareness and knowledge among community colleges\u27 personnel

An investigation of the deformation textures of cobalt

Deformation textures of various cobalt structures as a result of cold rolling together with some annealing textures were studied. The textures of cobalt were determined using a modification of the Schulz-Decker Geiger counter technique. Pole figures of the (1011), (0001) and (1010) planes were constructed. Also, a study of the microhardness of cobalt was made. Microhardness tests were performed on various cobalt structures, in both the cold rolled and unworked conditions. The microhardness was found to vary with the source of the cobalt, the crystal orientation, and the amount of deformation and twinning. Deformation lines about the hardness impressions diffused and became broader with time, indicating that partial self-relief of the imposed stress may take place. Textures of electrodeposited cobalt in (1) the as- deposited condition; (2) cold rolled eight percent without an initial anneal; and (3) cold rolled twenty percent with an initial anneal above the allotropic transformation were studied. Electrodeposited cobalt was found to have mainly a [1010] texture with a large spread toward a [1120] texture. The texture of the deposited cobalt with eight percent reduction by rolling was unchanged from the original texture. However, twenty percent reduction by rolling after annealing above the allotropic transformation produced a (0001) \u3c1120\u3e texture with partial retention of the original [1010] texture. The texture of the as-deposited cobalt could not be completely destroyed by heat treatment. Cold-rolled textures of sintered cobalt powders and annealed sponge were determined. The textures of both were practically the same. The texture can be described as (0001) \u3c1120\u3e in which the (0001) planes are rotated twenty to twenty-five degrees in the rolling direction from the rolling plane normal with the \u3c1120\u3e directions rotated twenty to twenty-five degrees in the transverse direction. The textures obtained are representative of cobalt textures up to approximately fifty or sixty percent reduction. The deformation textures of cobalt were examined theoretically by the Calnan and Clews method of texture analysis. From these theoretical considerations, the deformation mechanisms occuring during cold rolling of cobalt were determined to be (0001) [1120] slip and {1012} twinning. A study of these deformation mechanisms in tension and compression allowed a theoretical (0001) pole figure to be constructed. The construction of this pole figure was made from considerations of the rotations involved in tension and compression during deformation. Annealing textures of rolled electrodeposited cobalt were also studied. The temperatures used were 385°F and 720°F, the latter being above the recrystallization range but below the allotropic transformation. The textures resulting from the annealed rolled as-deposited cobalt are not representative of annealing textures because of the partial retention of the as-deposited texture throughout all the physical operations performed on the material --Introduction, pages 1-3

Integration of a Large Text and Audio Corpus Using Speaker Identification

We report on an audio retrieval system which lets Internet users efficiently access a large text and audio corpus containing the transcripts and recordings of the proceedings of the United States House of Representatives. The audio has been temporally aligned to corresponding text transcripts (which are manually generated by the U.S. Government) using an automatic method based on speaker identification. This system is an example of using digital storage and structured media to make a large multimedia archive easily accessible. Introduction In the United States, the text of proceedings of the two houses of the Congress has long been published in the Congressional Record. No systematic effort has been made, however, to record audio from the floor of the House and Senate. In 1995, the non-profit Internet Multicasting Service (IMS) began sending out live streaming audio to the Internet and making complete digital audio recordings of the proceedings on computer disks. The challenge was to ..

Detecting and Mitigating Denial-of-Service Attacks on Voice over IP Networks

Voice over IP (VoIP) is more susceptible to Denial of Service attacks than traditional data traffic, due to the former's low tolerance to delay and jitter. We describe the design of our VoIP Vulnerability Assessment Tool (VVAT) with which we demonstrate vulnerabilities to DoS attacks inherent in many of the popular VoIP applications available today. In our threat model we assume an adversary who is not a network administrator, nor has direct control of the channel and key VoIP elements. His aim is to degrade his victim's QoS without giving away his presence by making his attack look like a normal network degradation. Even black-boxed, applications like Skype that use proprietary protocols show poor performance under specially crafted DoS attacks to its media stream. Finally we show how securing Skype relays not only preserves many of its useful features such as seamless traversal of firewalls but also protects its users from DoS attacks such as recording of conversations and disruption of voice quality. We also present our experiences using virtualization to protect VoIP applications from 'insider attacks'. Our contribution is two fold we: 1) Outline a threat model for VoIP, incorporating our attack models in an open-source network simulator/emulator allowing VoIP vendors to check their software for vulnerabilities in a controlled environment before releasing it. 2) We present two promising approaches for protecting the confidentiality, availability and authentication of VoIP Services
