Investigation Of Insect-Weed Interactions In The Rice Agroecosystem, Kelly V. Tindall

LSU Doctoral Dissertations

Interactions between graminaceous weed and insect pests of rice and between management practices for these pests were investigated. Studies were conducted to examine preference and performance of rice water weevil, Lissorhoptrus oryzophilus Kuschel, on several weeds commonly found in rice fields. Several weeds were more preferred than rice, and larvae were present on several dicotyledonous weeds, suggesting the host range of L. oryzophilus is broader than previously thought. Effects of the presence of barnyardgrass, (Echinochloa crus-galli Beauv.), on rice stink bugs, Oebalus pugnax F., and L. oryzophilus populations in rice fields were investigated. Presence of barnyardgrass and the synchrony …

The Relation Between Knowledge Of Adhd And Treatment Acceptability In A Multi-Disciplinary Pediatric Clinic, Rebecca Owen Currier

LSU Doctoral Dissertations

Behavior modification and medication have been proven to be the most effective interventions for children with ADHD. For these treatments to be effective, utilization of mental health care services as well as compliance with treatment recommendations is necessary. There has been shown lower care utilization among minorities for the treatment of behavioral disorders. In addition, lack of adherence among these populations to ADHD treatment is not explained by SES, parenting stress, or family coping. An alternative explanation may be parental knowledge of ADHD and opinions of commonly used treatments. The present investigation examined the effect of a brief knowledge intervention …

Obvious To Whom? Evaluating Inventions From The Perspective Of Phosita, Rebecca S. Eisenberg

Articles

In this Article, I consider the possibility of giving the USPTO input from currently active technological practitioners in evaluating the obviousness of claimed inventions. Such input could potentially serve three useful functions. First, it could improve the accuracy of USPTO decisionmaking by providing access to the perspective of actual practitioners as to the obviousness of inventions from the perspective of the hypothetical PHOSITA. Second, it could help the USPTO document the evidentiary basis for rejections that rest in part upon tacit knowledge within technological communities. Third, it could provide a quality control mechanism that would improve the credibility of USPTO …

Bioevaluation Of Insecticidal And Repellen Plants From Central Region Of Kenya And Chemical Identification Of Bioactive Derivatives, Silas Khamala Simiyu

All Master’s Theses

Despite considerable control efforts, malaria still remains the most prevalent and devastating disease in the tropics. With more than 40% of the world population at risk, malaria undermines the welfare of several South American, Asian and African states, endangering the survival of children (killing one child every 30 seconds) and straining scarce resources. It is estimated that US $ 2 billion is spent on malaria control and treatment programmes in Africa annually. The problem is becoming increasingly difficult to manage because of the continuous intensification and spread of resistance to anti-malarial drugs by the parasites. This poses a serious threat …

Expression Of The Glossina Proteolytic Lectin (Gpl) Gene In Tsetse Flies And Other Haematophagous Arthropods, Marion Burugu Warigia

All Master’s Theses

African animal trypanosomosis, transmitted by the tsetse fly (Glossina spp.) remains a major constraint to food security in areas of Africa that hold the continent's greatest potential for expanded agriculture production. The flies also transmit the parasite responsible for human sleeping sickness. Other haematophagous arthropods like stable flies also transmit trypanosomes mechanically. Mechanical transmission only accounts for a small percentage (-16 % ) of the trypanosomes transmission since the haematophagous arthropods do not provide an environment for tr)-panosome development within their tissues unlike in tsetse flies. The life cycle of the parasitic African trypanosome in its invertebrate vector begins when …

Biochemical Examination And Identification Of Botanicals Active Against Adult Anopheles Gambiae From The Coastal Region Of Kenya, Josiah Ochieng Odalo

All Master’s Theses

Malaria still remains one of the most important tropical parasitic and vector-borne diseases in terms of geographical distribution, incidence, the extent of the morbidity and mortality. It is endemic in about 100 countries inhabited by >40010 of the world's population with at least 500 million clinical cases reported each year. More than 90% of these cases occur in Africa, where it is one of the most important causes of morbidity and mortality among infants, young children, pregnant women, non-immune travelers, refugees, displaced persons and labourers entering endemic zones. Management of malaria has become more difficult due to the development of …

Management Of Marine Wildlife Disturbance, C. Kelly, G. A. Glegg, C. D. Speedie

School of Geography, Earth and Environmental Sciences

In recent years, concerns have been raised about the health and status of a range of marine species in UK waters, including the bottlenose dolphin (Tursiops truncatus) and basking shark (Cetorhinus maximus). Disturbance and harassment from increasing inshore leisure traffic and a fascinated public have been identified as potential threats to these large marine species. This concern is coupled with a legislative framework that is perceived to be less effective in protecting key species than it could be, and difficult to enforce. This study examined the extent of anthropogenic disturbance to a range of marine wildlife in inshore waters around …

Capitalism And Freedom -- For Whom? Feminist Legal Theory And Progressive Corporate Law,, Kellye Y. Testy

Articles

Beginning at least in the 1980s, the version of corporate law and governance prevailing in the U.S. (as well as widely exported to other nations) was a radically privatized one, treating the corporation as a contractual arrangement for maximizing shortterm share price in a laissez faire global marketplace. Though many robust and varied social movements, many of which were bolstered by the 1999 WTO protests in Seattle, have been and are engaged in challenging this hegemony from many angles, few have found their way into corporate law reform. That is not to say, however, that there are no progressive legal …

Cash For Kidneys? Utilizing Incentives To End America's Organ Shortage, Steve P. Calandrillo

Articles

This article addresses the growing organ shortage in America, analyzes current donation and procurement law, and explores both monetary and nonmonetary incentives aimed at eliminating the worsening crisis.

Part I details the law governing human organ donation. Under both the Uniform Anatomical Gift Act (“UAGA”) and the National Organ Transplant Act (“NOTA”), no donor of a human organ may receive “valuable consideration” for providing it. Congress’ intention was simply that the organ recipient be given the “gift” of life—not one which she had to purchase on the market. In reality, the consequences of the Act bear little resemblance to its …

Vanishing Vaccinations: Why Are So Many Americans Opting Out Of Vaccinating Their Children?, Steve P. Calandrillo

Articles

Part I of this Article details the historical development and medical achievements made possible by vaccines. From Edward Jenner to Jonas Salk to Albert Sabin, immense strides have been made in eradicating or substantially eliminating some of the worst diseases in human history. Smallpox, polio, measles, mumps, rubella, diphtheria, pertussis, tetanus, influenza, hepatitis A and B, and even the chicken pox are all now largely preventable.

Literally hundreds of millions of deaths have been avoided and many more lives markedly improved, to say nothing of the financial ramifications for the American healthcare system. All fifty states have therefore enacted compulsory …

Technology Forecasting Using Data Envelopment Analysis, Oliver Lane Inman

Dissertations and Theses

The ability to anticipate future capabilities of technology products has broad implications for organizations. Technological forecasting allows management to improve resource allocation, make better staffing decisions, and more confidently plan facilities and capital expenditures. Technology forecasting may also identify potential new markets and opportunities, such as finding ways to exploit current technology beyond its originally intended purposes.

Modern technology forecasters use an array of forecasting methods to predict the future performance of a technology, such as time-series analysis, regression, stochastic methods, and simulation. These quantitative methods rely on the assumption that past behavior will continue. Shortcomings include their lack of …

Age Analysis On Different Bony Structures Of Perch (Perca Fluviatilis L. 1758) Inhabiting Derbent Dam Lake (Bafra, Samsun), Nazmi̇ Polat, Derya Bostanci, Savaş Yilmaz

Turkish Journal of Veterinary & Animal Sciences

The age determination method and its accuracy are the most important subjects for the evaluation of age-length-weight relations in fisheries biology, since estimates of survival, growth and mortality rates, analysis of year-classes, and recruitment all depend on age structure. Thus, the aim of this study was to determine the most reliable bony structure for ageing Perca fluviatilis inhabiting Derbent Dam Lake. Scales, vertebrae, otoliths and opercles removed from each fish were examined by 2 readers 3 times, without referring to any information except for the date of capture and gonad state. The precision of the readers was estimated and ageing …

The Third Alphabet Of Life: Carbohydrate-Protein Interactions, Kami̇l Seyrek

Turkish Journal of Veterinary & Animal Sciences

The structural diversity of oligosaccharides found in glycoconjugates is enormous. This is due to the number of different ways in which sugar monomers may be linked to each other regarding linkage position, anomeric configuration, pyranosidic or furanosidic ring form and chain branching. It has been proposed that these factors contribute to the exquisite potential of oligosaccharides to establish a code system of biological information. The information contained in these structures is decoded by complementary sites present on carbohydrate binding proteins (lectins).

The Effect Of Gnrh Administration On Plasma Progesterone And Reproductive Performance In Ewes, Mehmet Aki̇f Çam, Mehmet Kuran, Erdoğan Selçuk

Turkish Journal of Veterinary & Animal Sciences

Two experiments were carried out to investigate the effect of GnRH administration at mating and on day 12 post-mating on the reproductive performance of Karayaka and Sakız x Karayaka (F_2) crossbred sheep. In the first experiment, ewes were allocated into a control group (K, n = 27), and groups administered 4 µg GnRH at mating (A, n = 27), on day 12 post-mating (AS, n = 30) and both at mating and on day 12 post-mating (AAS, n = 30). GnRH administration in the A and AS groups increased plasma progesterone concentrations (P < 0.01). The pregnancy rate at first mating in the AS group (86.7%) was higher than those in the ASS (66.7%), A (51.9%) and K (51.9%) groups (P < 0.01). There was no difference between the treatment groups in terms of litter sizes (1.31, 1.21, 1.21 and 1.20 for AS, K, A and ASS, respectively). In the second experiment, ewes were allocated into 2 groups, a control group (K, n = 70) and a group administered 4 µg GnRH on day 12 post-mating (AS, n = 73). The pregnancy rate at first mating was 71.4% and 80.8% (P > 0.05) and litter size was 1.24 and …

Introducing A New Approach To Estimating Red Meat Production In Turkey, Fahri̇ Yavuz, Carl R. Zulauf

Turkish Journal of Veterinary & Animal Sciences

A common concern with official estimates of red meat production in Turkey is that they underestimate the level of production. One of the frequently cited reasons is that unregulated slaughter is undercounted. This study uses an estimation method based on the biology of red meat production to examine the potential impact of this undercounting. The production estimates obtained for 1991-1998 using this biological-based method exceed the numbers estimated by official organizations, but fall within the range of estimates obtained from other proposed approaches to estimating red meat production.

The Reproduction Biology Of Chub (Leuciscus Cephalus L. 1758) In Topçam Dam Lake (Aydın, Turkey), Hüseyi̇n Şaşi

Turkish Journal of Veterinary & Animal Sciences

In this study, the reproduction biology of 332 chub (Leuciscus cephalus L. 1758) was studied from June, 1999, to June, 2000, on a monthly basis in Topçam Dam Lake. Egg numbers were estimated in 65 females caught just prior to spawning. The sex and age compositions of chub were determined. The specimens were composed of 27.11% males and 72.89% females. Male and female chub become sexually mature in the second year of their life spans. Spawning is in March and April. The fecundity of chub varies from 2100-66,400 per female. The average egg diameter was between 0.391 and 0.744 mm …
