Modification of nektonic fish distribution by piers and pile fields in an urban estuary
No full textLarge urban piers degrade habitat value for several estuarine benthic fish species by shading, but their effects on mobile nektonic species is less well understood due to sampling challenges. Dual Frequency Identification Sonar (DIDSON) allowed equal access to sampling in the water column of structured shaded and unshaded vs. open environments in both dark and light conditions by methods similar to video but without light. Sampling (n = 228, 5-minute transects) occurred under and around four large municipal piers of varying dimensions in the Hudson River estuary during day and night from summer and fall in 2007 - 2009. The distribution of small (5 - 25 cm in length) and large (25 – 850 cm) fishes were analyzed separately in recognition of functional guild differences. Small fishes occupied open water, shaded under-pier, and un-decked relict piling habitats, but were significantly more abundant during the day in open unshaded water than under adjacent piers or in piling habitats.. Small fish occurred under 3 of 4 piers of varying size and configuration at 10 - 20% of the median abundances of adjacent open water. However, while schools were rare under piers they could be very large, so that abundance greatly exceeded mean open water abundance variance so as to preclude confidence in differences among piers. The differences among habitats was not significant at night, and the difference among piers was also not significant at night. School membership for small fish appeared to mitigate adverse effects of shading and may influence scaling of their response to shading and could therefore influence pier design. Large (>25 cm) predatory fish were uncommon but responded similarly to habitat effects as did small fish. Habitats did not segregate fish by guild as small forage fish co-occurred in 65.8% of samples with large piscivores. Studies that provide species-specific and mechanistic interpretation of dynamic habitat use as well as further quantification of scaling effects could improve our understanding of how fishes respond to piers and other structures on urban shorelines.Peer reviewed
Kenneth M Alexander - Author and Artist
No full textI was born to Dennis and Kathleen Alexander in a single motor garage at 21 Limerick Road in Athlone. In those days, the midwife would do her rounds on a bicycle at the time when the stork was seen flying over the now-collapsed, missing going, gone forever Athlone Towers. Either that or she went to the foot of Table Mountain and placed a hollowed out pumpkin with a precision cut hole in one side. The monkey would come, stick his or her hand in the hole, grab some pips and in trying to pull its hand out in a fist, it gets stuck. The midwife then pounces on the helpless monkey, knocks it out with her case, and then stuffs "it" into that same black case and off she motors on her "dik" wheel bicycle to deliver the latest addition to an Athlone family. The monkey cries with relief when let out of the case. I have since moved on from that belief system. For some reason, the majority of the employers I worked for still believe that. In fact, far too many white people still do. To them we are monkeys and they pay us with peanuts

The effect of parental involvement as perceived by parents and teachers of the Navasota Elementary and John C. Webb Middle Schools (Navasota ISD, Texas)
No full textVita.The purpose of this study was to address three questions regarding parental involvement: 1. What perceptions do the parents of children at the Navasota Elementary School and John C. Webb Middle School in the Navasota ISD have regarding parent involvement? 2. What perceptions do the teachers have regarding parent involvement in the Navasota Elementary School and John C. Webb Middle School in the Navasota ISD? 3. Are there differences between the perceptions held by parents and teachers regarding parent involvement as seen in the Navasota Elementary School and John C. Webb Middle School in the Navasota ISD? In order to accomplish this, the researcher utilized a parent survey and a teacher survey adapted from similar instruments utilized for a National Institute of Education research project on parental involvement. These instruments w ere used to gather the perceptions of parents and teachers regarding parent involvement in the Navasota ISD at Navasota, Texas. The perceptions of parents and teachers were assessed on Likert type scales. The responses were indicated using a 4-point scale of 1 (strongly disagree) to 4(strongly agree). The following conclusions were drawn based upon the data gathered by the researcher: 1. Navasota ISD parents gave strong support to their involvement in the education of their children. This is evidenced from the support to the statement "I should make sure that my children do their homework" which peaked to the first rank with a mean level of agreement of 3.689. 2. Teachers in grades kindergarten through fourth grade had favorable inclinations toward parent involvement. The responses to the statement "most parents who assist in classrooms become more involved with their child's learning" ranked second with a mean of 3.543. 3. Both parents and teachers in the Navasota ISD indicated support for the various roles that parents could play in the schools, which is seen from the favorbale response to the statement "make the parents feel more welcome in the school". 4. No expression of any significant barriers to the development of an effective model parent involvement program in the Navasota ISD was witnessed

James Webb Throckmorton: the life and career of a southern frontier politician, 1825-1894
No full textMany scholars of the Reconstruction era have examined
James Webb Throckmorton??s political career between 1860 and
1867 and have revealed that his racist views helped hasten
the end of Radical Reconstruction in Texas. However, these
scholars have not explained the motivations behind
Throckmorton??s political ideology, nor have they explained
adequately the origins of the North Texan??s racism. This
dissertation focuses on these critical issues by examining
the development of Throckmorton??s personal and political
beliefs between 1850 and 1874. It shows that
Throckmorton??s political ideology was influenced by four
primary factors: his early experiences on the North Texas
frontier, his desire to create a community on the frontier
that was primarily designed to be a haven for white
settlers, his commitment to political conservatism which
evolved from his early affiliation with Whig political
ideology, and his quest to bring economic improvement to
the North Texas region. In contrast to other scholarly
works on Throckmorton which claim that the North Texan??s
political views were contradictory and inconsistent, this
study demonstrates that Throckmorton??s ideological beliefs
remained constant and changed little over time. His
commitment to preserving the whiteness of the frontier, to
protecting the settlers of his home region, to conservative
political ideology, and to internal improvements,
especially railroads, never wavered during one of the most
turbulent periods in Texas politics. This study also
reinforces several important conclusions about the South in
the nineteenth century: The region was never a homogeneous
society; southern racism was multifaceted; and southern
settlers migrating westward, especially those from the
Upper South, viewed the frontier as a potential escape from
the political and social dominance of large slaveholders
Selected factors associated with performance rating of male country extension agents in Texas
No full textPurpose The purpose of this study was to identify factors associated with the performance ratings of male county Extension agents in Texas so that criteria might be developed for selecting new county personnel who will be effective Extension educators. Specific objectives to accomplish this purpose were: 1. To identify factors common to male county Extension agents who are rated high, medium, or low in performance. 2. To determine if a significant association exists among factors peculiar to agents that are rated high, medium, or low in performance. 3. To develop criteria for use in recruitment, selection and employment of male county personnel who would develop into superior Extension educators. Procedure Data were obtained from the permanent records of the Texas Agricultural Extension Service utilizing the agent's personal data file, the agent's college transcript, and the Performance Review rating of the agent. The data were analyzed by the Data Processing Center at Texas A&M University. Variables of the continuous nature were treated by analysis of variance while discrete variables were tested by the use of chi square. A sample of 80 male county Extension agents was selected to study the association of 26 factors to performance rating. ..

Effects of lysine nutrition on production characteristics and ammonia excretion of red drum Sciaenops ocellatus
No full textDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references (leaves 35-40).Issued also on microfiche from Lange Micrographics.The red drum (Sciaenops ocellatus) has traditionally been an important commercial and recreational fish species in the Gulf of Mexico; therefore, its aquacultural production for food and for stock enhancement continues to develop. The minimum dietary lysine requirement of juvenile red drum was previously quantified to be 1.55% of a 35% crude protein (CP) diet (4.4% of dietary protein). However, red drum are usually fed diets containing 40 to 50% CP under commercial production. Therefore, the purpose of this study was to reevaluate the dietary lysine requirement of red drum as a function of dietary CP, and determine the effects of dietary manipulations on ammonia excretion. Control diets at 35 and 45% CP contained only the intact protein provided by a 50/50 mixture of red drum muscle and wheat gluten. Four experimental diets at each CP level contained the mixture (64% of CP) and crystalline amino acids (34% of CP) to provide lysine levels above and below the previously determined requirement. Each diet was fed to triplicate groups of 20 juvenile red drum initially averaging 3.4 g/fish in 110-l aquaria containing brackish (7ppt) water at 27��1 ��C and operated in a recirculating mode. Diets were fed at a fixed rate approaching apparent satiation twice daily for 6 weeks after which total ammonia nitrogen (TAN) excretion at 4-h postprandial was determined. Diets supplemented with crystalline amino acids supported similar weight gain (94 - 98%) as that obtained by fish fed control diets with intact protein. Based on weight gain, protein efficiency ratio (PER), and protein conversion efficiency (PCE) data, the minimum dietary lysine requirement was not influenced by dietary CP. Broken-line regression analysis of weight gain data of fish fed increments of lysine in both 35 and 45% CP diets yielded a lysine requirement estimate of 1.49��0.07% of diet, confirming the previously determined value. Weight gain and TAN excretion were significantly (P#0.05) higher in fish fed the 45% CP diets while PER and PCE values were significantly reduced. Lysine deficiency also resulted in elevated ammonia excretion, but significant reductions were not achieved when dietary lysine was at or above the established requirement
