Dynamic Acromiohumeral Interval Changes During Scapular Plane Arm Motions, Melissa Deen Thompson 2010 Louisiana State University and Agricultural and Mechanical College

Dynamic Acromiohumeral Interval Changes During Scapular Plane Arm Motions, Melissa Deen Thompson

LSU Doctoral Dissertations

This purpose of this dissertation is to explore changes in the acromiohumeral interval during dynamic motion in the scapular plane. All of the experiments were completed in the Football Operations Athletic Training Room at Louisiana State University. The first experiment which investigated dynamic acromiohumeral interval changes in baseball players during a loaded and unloaded scaption exercise from 0°-75°, has been accepted for publication by the Journal of Shoulder and Elbow Surgery (in press, 2010). The mean acromiohumeral interval (AHI) for unloaded and loaded scaption decreased significantly (p<.001) from the arm at the side until 45° and loaded scaption narrowed AHI at 60° (p=.005) and 75° (p=.003). The second experiment investigates AHI and scapular upward rotation (SUR) changes in baseball and softball players during scaption exercises from 0°-75°. Significant load related narrowing of the AHI at 45°(p=.005), 60°(p=.001), and 75°(p<.001) and a significant load-position interaction (p=.001) at 0° and 75°was observed for all subjects. No gender differences in SUR or AHI were found. AHI and SUR displayed moderate positive correlations at 30° for both the unloaded scaption (r=.648, p=.001) and the loaded scaption (r=.445, p=.038) however, no significant relationships were present at 0°, 45°, 60° or 75°. The third experiment compared dynamic acromiohumeral interval and scapulohumeral rhythm changes in trained and untrained females during scaption exercises from 0°-90°. In general, AHI was maximal with the arm at the side and declined significantly (p<.001) during arm elevation until 60°, but increased significantly (p<.001) between 60° and 90°. Significant load related narrowing of the AHI at all positions (p<.05), a more negative SUR at 0° (p<.001) and a more positive SUR at 90° (p=.009) was observed for all subjects. Female athletes had significantly stronger external rotators (p<.001), larger overall AHI (p=.003) and more SUR (p=.008) than untrained females. Significant positive correlations (p<.05) between AHI and SUR were observed at 0°, 30°, and 60° during both loaded and unloaded scaption.

Coex-Rank, An Approach For Microarray Combined Analysis-Oarray Combined Analysis: Applications To Pparγ Related Datasets Applications To Pparγ Related Datasets, Jinlu Cai

Theses and Dissertations

Microarrays have been widely used to study differential gene expression at the genomic level. They can also provide genome-wide co-expression information. Robust approaches are needed for integration and validation of independently-collected datasets which may contribute to a common hypothesis. Previously, attempts at meta-analysis have contributed to solutions to this problem. As an alternative, for microarray data from multiple highly similar biological experimental designs, a more direct combined approach is possible. In this thesis, a novel approach is described for microarray combined analysis, including gene-level unification into a virtual platform followed by normalization and a method for ranking candidate genes based ...


Who Do You Think You Are? Constructing Self/Identity In Women's Rugby Through Aggression, Control And Unacceptable Behavior, Shannon M Baird 2010 University of Iowa

Who Do You Think You Are? Constructing Self/Identity In Women's Rugby Through Aggression, Control And Unacceptable Behavior, Shannon M Baird

Theses and Dissertations

Some behaviors in sport may be labeled: bad, unnecessary and distasteful. Sport psychologists have used concepts of aggression to understand and lessen these behaviors. To date, most research has conceptualized aggression as a product of individual cognition. Specifically, aggression is defined in the sport psychology literature as any behavior motivated by the intent to harm one's opponent (Baron, 1977; Bredemeier & Shields, 1986b; Husman & Silva, 1984; Kirker, Tenenbaum & Mattson, 2000). Consequently, sport psychology analyses of aggression tend to reproduce take-for-granted conceptions of aggression as male, physical and other-directed. To better understand sport aggression, it has been argued that symbolic interactionism has much to offer (Baird & McGannon, 2009). By utilizing symbolic interactionism we can reconceptualize aggression as a social construct given meaning in and through interaction with self and others. From this perspective, self notions and interactions with others are important "locations" of meaning making and are significant in the study of behavior.

The present study used symbolic interactionism to explore female rugby players' experiences of aggression and how they interpret, define and structure experiences relative to self development. In conjunction with participant-observation, 12 semi-structured interviews with female rugby players ages 18-45 were conducted to explore: (1) how do women define themselves as ruggers/how do they (re)produce these identities in and out of rugby, (2) how do women define and experience aggression, and (3) how are these accounts used in the construction of self/identity?

Data emerging from interviews and observations suggested that athletes defined and experienced behavior in ways challenging contemporary sport psychology conceptualizations of aggression. The participants often used the word aggression to describe forceful and physical play. In sport psychology literature, this is typically referred to as assertive behavior (Husman & Silva, 1984; Tenenbaum, Saks, Miller, Golden, & Doolin, 2000) and aggressive behavior is a label reserved for unacceptable behavior motivated by the intent to harm (Tenenbaum et al., 2000). According to the women in this study, unacceptable behavior was not defined by intent; rather, unacceptable behavior was a negotiated space that was constructed through notions of lack of control. That is, if a player was constructed as out of control, that player was seen as ...


New Binary Ti Vectors With Co-Directional Replicons For Agrobacterium Tumefaciens-Mediated Transformation Of Higher Plants, Seokhyun Lee 2010 Louisiana State University and Agricultural and Mechanical College

New Binary Ti Vectors With Co-Directional Replicons For Agrobacterium Tumefaciens-Mediated Transformation Of Higher Plants, Seokhyun Lee

LSU Doctoral Dissertations

Small, high-yielding binary Ti vectors of Agrobacterium tumefaciens were constructed. All four basic components of the vector, ColE1 replicon (715 bp) for Escherichia coli, VS1 replicon (2,659 bp) for A. tumefaciens, a bacterial kanamycin resistance gene (999 bp), and the T-DNA region (170 bp), were modified to reduce the vector size to 4,566 bp and to introduce a number of mutations to increase the copy number and other functionality. The transcriptional direction of VS1 replicon can be the same as that of ColE1 replicon (co-directional transcription), or opposite (head-on transcription) as in the case of widely used vectors ...

Evaluation Of Green Tea Extract As A Glazing Material For Shrimp Frozen By Cryogenic And Air-Blast Freezing, Srijanani Sundararajan

LSU Master's Theses

Green tea (Camellia sinensis) extract (GTE) is rich in polyphenolic compounds, especially catechins that are potent antioxidants. The antioxidant property of GTE may make it ideal for use as a glazing solution for suppressing lipid oxidation in shrimp (Litopenaeus setiferus) during frozen storage. In this study, GTE was evaluated as a glazing material for shrimp frozen by air-blast (BF) and cryogenic freezing (CF). Two percent, three percent and/or five percent green tea extract solutions (2GTE, 3GTE, 5TGE) were used for glazing. Distilled water glazed (GDW) and non-glazed (NG) shrimp were used as controls. The GTE was characterized by measuring ...

Copper Oxide Wire Particles In Feed Pellets For Controlling Gastrointestinal Nematode Infection In Ewes And Lambs, Sarah Tammy Nicole Orlik 2010 Louisiana State University and Agricultural and Mechanical College

Copper Oxide Wire Particles In Feed Pellets For Controlling Gastrointestinal Nematode Infection In Ewes And Lambs, Sarah Tammy Nicole Orlik

LSU Master's Theses

Gastrointestinal nematode parasites cause extensive damage to small ruminants, and Haemonchus contortus is a major concern to production. In the past, small ruminants were dewormed at regular intervals and control methods were based primarily on the use of anthelmintics. At present, anthelmintic resistance has been reported worldwide and has developed into a serious problem for small ruminant management programs. In view of this, alternate control methods are needed. One alternative method is the use of copper oxide wire particles (COWP). Three independent trials were conducted during Spring, Summer, and Fall of 2008. Two trials evaluated the effect of COWP in ...


Three Essays On The Role Of Amenities As An Economic Development Strategy, Junpyo Hong 2010 Louisiana State University and Agricultural and Mechanical College

Three Essays On The Role Of Amenities As An Economic Development Strategy, Junpyo Hong

LSU Doctoral Dissertations

It is well known that an amenity is a key driving engine to regional economic growth. However, the site-specific nature of an amenity can characterize them as public goods. Due to this characteristic, local governments have difficulty optimally supplying amenities. This dissertation tries to find relationships between an amenity and economic growth. Three empirical papers comprise the original research in this dissertation. The findings of the meta-analysis in the first essay suggest little methodological diversity exists among researchers linking amenities to economic growth., I do find that employment growth is more likely related to man-made amenities even in research on ...


Formation Of The Neural Tube Epithelium Basement Membrane During Secondary Neurulation In The Chick Embryo, Leslie Ann Mataya 2010 University of Northern Iowa

Formation Of The Neural Tube Epithelium Basement Membrane During Secondary Neurulation In The Chick Embryo, Leslie Ann Mataya

Honors Program Theses

Neurulation, the formation of the neural tube, is an important process in the development of vertebrates. Because this organ ultimately becomes the central nervous system of the organism, the proper development of a fully-functioning neural tube is paramount to its survival. Neural tube defects, like spina bifida and anencephaly, are among the most common congenital malformations present in live human births. The prevalence of these defects is a definite concern to medicine and human health.

Toxicity Interaction Of Fipronil And Imidacloprid Against Coptotermes Formasanus, Pan Luo

LSU Master's Theses

The Formosan subterranean termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), is considered one of the most destructive structural pests in the world, especially in warm and humid areas. Insecticide application is an effective strategy in termite control. In recent years, non-repellent insecticides have become popular for their high efficacy due to delayed toxicity and horizontal transfer. Fipronil (registered name Termidor®) and imidacloprid (registered name Premise®) have been applied to the perimeter of millions of houses in the United States. Fipronil and imidacloprid have different modes of action which may produce a synergistic effect when combined. There have been no studies on ...

Papers in Plant Pathology

Paramecium bursaria chlorella virus 1 (PBCV-1), a member of the family Phycodnaviridae, is a large double-stranded DNA, plaque-forming virus that infects the unicellular green alga Chlorella sp. strain NC64A. The 330-kb PBCV-1 genome is predicted to encode 365 proteins and 11 tRNAs. To monitor global transcription during PBCV-1 replication, a microarray containing 50-mer probes to the PBCV-1 365 protein-encoding genes (CDSs) was constructed. Competitive hybridization experiments were conducted by using cDNAs from poly(A)- containing RNAs obtained from cells at seven time points after virus infection. The results led to the following conclusions: (i) the PBCV-1 replication cycle is temporally ...
