Annual energy flow and mean annual biocontent of eighteen compartments were determined for a 0.94 ha north central Texas pond ecosystem. Annual primary production was 7,780 kcal m^-2 yr^-2, and community production-to-respiration ratio was 1.49. One-third of annual primary production accumulated on the substrate as silt and sedimentation. Community production, production-respiration ratio, and biocontents of all compartments except aquatic insects were large in summer, small in winter. Biocontents of four trophic levels in the pond were all of the same order of magnitude, approximately 50 kcal m^-2. Suspended and benthic organic material forprimary consumers and terrestrial insects for tertiary consumers were substantial allochthanous energy imports into the pond system.

The present study investigated the relationship of 16 Personality Factor (16 PF) Scores to institutional adjustment, educational level, recidivism, and escapism of 665 prisoners in a maximum security prison. Two phases of data analysis were conducted. Multiple two-tailed Students' t tests resulted in significant differences on all 16 PF Factor Scores between prisoners and Cattell adult norm group. Significant differences were also found between prisoners and Cattell prisoner norms. In phase two, four multiple linear regression models were constructed. Significant 16 PF scales, age, and educational differences were found within the prisoner sample. Possible implications of the use of the 16 PF in regression models in paramorphic clinical prediction programs are discussed.

Serotonin has been implicated as a modulator of feeding behavior. This experiment was designed to alter brain serotonin levels through dietary means in hypothalamic ventromedial-lesioned and unlesioned rats. Daily food, water, and animal weights were measured. The purpose was to determine if VMH lesions altered the feeding pattern found in unlesioned rats. Although food intake for tryptophanenriched diets and tryptophan-deficient diets did not differ from their respective control groups, in some cases gross animal weights did differ significantly between experimental and control groups and between lesioned and unlesioned groups. A proposed model explains how a "low" energy signal and a "high" protein signal cycles amino acids through gluconeogenesis to comPensate for an energy deficit.

The purpose of this study was to determine the various value levels that may be affecting communication in the church and to discover the predominant levels of psychological existence. Data was collected using the Value for Religion test. A total of 288 college and seminary students were tested. Comparisons of the differing scores of demographic variables formed the bases of the conclusions drawn in the study. Significant relationships were found between one's personal value cluster and sex, career intention, and type of college attended. Much research is still needed in the area of value levels in religion. Hopefully, this research will contribute to the success of religion in the future.

Anxiety levels of partially sighted were compared with totally blind people. Using the Anxiety Scale for the Blind, the primary hypothesis tested was that the partially sighted would manifest more anxiety than would the totally blind. The study was designed to ascertain whether the primary hypothesis would hold within the structure of this study, and to obtain information useful in future anxiety studies of the visually handicapped. A residential center for the blind furnished subjects, facilities, and biographical data. The primary hypothesis lacked statistical significance at the .05 level as did comparisons of anxiety levels by age, sex, economic need, and age at onset. The use of a different instrument may be indicated for future studies.

Title: Habitual physical activity of Portuguese university students in the period of summer holidays Aim of the study: The aim of study is to evaluate habitual physical activity of Portuguese university students and to find out if they are meeting physical activity recommendations and could be seen as a sample of active population. Methods: Sample of the study was made of Portuguese university students, exactly students of physical education and sport sciences faculty. Sample size was 125 respondents, 81males and 44females. The sample refers to young adult age group from 18 years old, both genders. Instrument used was International physical activity questionnaire (IPAQ), long version. Data were collected electronically by Google Docs and then analyzed in Microsoft Excel 2007 and IBM SPSS Statistics 20. Results: Physical activity and sport scientist's students can be seen as a sample of active population. 122 (97.6%) respondents are meeting physical activity recommendations from which 87 (69.6%) are over-meeting these recommendations. PAL of the sample was high in 69,6%, moderate in 28% and low in 6,8% of the cases. No statistical significance was found between total physical activity score and academic year. The habitual physical activity of the sample is not influenced by their study curriculum....

This investigation sought to identify sound levels potentially harmful to directors' hearing, and examine the effects of band size, instrumentation, bandroom and playing ability on sound levels. The subjects were 2 elementary, 2 middle, and 4 high school bands, in 7 rooms, 10 to 66 members, and 26 students, beginning and advanced. A sound level meter was used. Sounds were measured in flat and A-weighted decibels. Sounds measured were steady state (>.5 sec.) and impulse (<.5 sec.). Results were compared with safety limits of OSHA, EPA and Baughn's study of safety limits (1966). Results show exceedences of limits used for comparison. Small rehearsal areas and younger players seemed to cause high levels in the tests. Further testing may prove potential hazards.

Approved for public release, distribution is unlimited / The term "security" has always been vague in terms of its definition. After the end of the Cold War, however, this vagueness increased as new paradigms emerged. Those studying security need a better understanding of the term "security" to deal with complex issues within the broadly understood discipline of security studies. This thesis describes the uncertain nature of security by analyzing: (1) various definitions of security and some of the terms directly related to it in different contexts; and (2) the empirical meaning of security by examining threats as indicators of "insecurity," based on the different characters of threats, and levels of analysis from the field of international relations. The thesis argues that regardless of the vague meaning of the term "security," empirically its parameters are quite certain and definable by the specification of threats as indicators of insecurity. This clarification of the meaning of security studies, in turn, makes it easier for scholars and policy-makers to deal with this increasingly important sphere of human life. / Captain, Polish Army

The Stenger Principle describes the observation that when two tones of the same frequency are presented simultaneously, a single tone is perceived only in the ear in which the tone is louder. This principle underlies the Stenger Test, which is used to identify the presence of unilateral nonorganic hearing loss (NOHL). Minimum contralateral interference levels (MCILs), which can be used to estimate true hearing thresholds in individuals with unilateral NOHL, are also based on this principle. In this study, the Stenger Principle is used to examine MCILs and the correspondence of the MCILs to true hearing thresholds in 16 adults with normal hearing. In Part I of the study, subjects were asked to feign a unilateral hearing loss. Average MCILs were 12.5, 15.1, and 13.5 dB HL for 1.0, 2.0, and 4.0 kHz, respectively. These were obtained with nearly equal interaural stimulus levels. The average difference between MCIL and true hearing threshold was 7.6, 9.7, and 8.9 dB, respectively. In Part II of this study, subjects were asked to make lateralization judgments for simultaneously presented tones with varying interaural intensity differences. Individual subject ratings were compared to MCILs obtained in Part I. Although most subjects showed the Stenger Effect with a midline percept of the two tones, variability between subjects existed. In some cases the Stenger Effect was not apparent until the tonal image was pulled nearly to the "poor" ear. Because of the potential differences in response bias (a client may show the Stenger Effect with a small shift in the tonal signal away from the "good" ear or may require the tonal signal to be fully lateralized to the "poor" ear), clinicians cannot predict exact hearing thresholds. Rather, it is useful to describe a range within which the true threshold will be. The 90% ranges (5th and 95th percentiles) calculated in this study were approximately 1 and 17 dB. That is, the MCILs for the majority of the subjects were within ~ 1 and 17 dB of true hearing thresholds.

The diploma thesis "Manifestations in the language levels of the 1st grade pupils of the regular elemntary school" consists of theoretical and practical part. The theoretical part deals with general terms from the area of speech and language development, describes the development of motor skills, auditory and visual perception. Furthermore, it describes individual language levels and the most common types of speech disorders encountered in primary school pupils. The research part of the thesis is devoted to the analysis of speech manifestations on individual levels of pupils of the first grade of the regular elementary school. The partial aim of the research is to analyze the gross, fine and oromotorics of the examined children, to analyze their auditory and visual perception and to analyze the quality of all language levels.
