Torsion Of A Wandering Spleen: A Rare Cause Of Acute Abdomen, Nwashilli N. Jude, Nwajei C. Onochie

Saudi Medical Journal

Wandering spleen is a rare condition that accounts for less than 0.25% of all indications for splenectomy. It is characterized by ectopic localization of the spleen owing to the lack or weakening of its ligaments. Torsion is the most common complication due to its long pedicle and high mobility, which may result in acute abdomen. We report a case of torsion in a wandering spleen in a 28-year-old male presenting with an acute abdomen that was treated by splenectomy.

Wernicke’S Encephalopathy Following Roux En Y Gastric Bypass Surgery, Azra Zafar

Saudi Medical Journal

Wernicke’s encephalopathy (WE) is a serious neurological disorder characterized by a classical triad of acute mental confusion, ataxia, and opthalmoplegia due to thiamine deficiency. It was initially described in chronic alcoholics; however, any condition resulting in poor nutritional status places the patient at risk of WE. Bariatric surgery is now considered as an emergent cause of WE. The number of bariatric surgery is increasing for morbid obesity. We present a case of a 40-year-old male who presented with confusion and difficulty in maintaining the balance while walking 3 months after Roux en Y gastric bypass surgery. Diagnosis of WE was …

Situational Judgment Test, Britt De Soete, Filip Lievens

Research Collection Lee Kong Chian School Of Business

In this article, we give an overview of situational judgment tests (SJTs) as selection instruments. Their history, basic characteristics, and development are presented. The available research evidence regarding their reliability, construct-related validity, criterion-related validity, incremental validity, subgroup differences, and test-taker perceptions is also reviewed. As a general conclusion, the increasing popularity of SJTs in personnel selection seems to be accredited to their potential to capture a variety of constructs and for different purposes. Additionally, SJTs are able to predict several job-related and/or academic criteria while at the same time offering prospects permitting to select for diversity.

Conveying The Adaptation Of Management Panaceas: The Case Of Management Gurus, Timothy Adrian Robert Clark, Pojanth Bhatanacharoen, David Greatbatch

Research Collection Lee Kong Chian School Of Business

In this chapter we examine how management gurus through the telling of epiphanic and non-epiphanic stories convey the level of adaptability of their ideas. We argue that for their ideas to leave the auditorium with the audience members they have to present them in ways which convincingly demonstrate that they are potentially pertinent to the variety of working lives of those who attend. Drawing on a Conversation Analytic approach, the chapter shows that in the post-story assessment the gurus use a double structure of humor then seriousness. The contrast between the light-heartedness of the story and the seriousness of the …

Supply Management In Multiproduct Firms With Fixed Proportions Technology, Onur Boyabatli

Research Collection Lee Kong Chian School Of Business

This paper studies the supply management of a primary input, where this input gives rise to multiple products in fixed proportions. My objective is twofold. First, I study fixed proportions technology under demand uncertainty in comparison with flexible and the dedicated technologies. I show that fixed proportions technology has a cost- pooling value over dedicated technology, which is larger than the capacity-pooling value of flexible technology over dedicated technology. I identify the critical role that demand correlation plays with the fixed proportions technology: In contrast to the capacitypooling value which decreases in demand correlation, the cost-pooling value increases in demand …

Bldc Motor Speed Measurement Using Zcp Detection For Fuzzy Speed Controlling., Mohamed Elksasy, Ahmed Ahmed, Amr Ali-Eldin, Faiz Areed

Mansoura Engineering Journal

Sensorless Brushless DC (BLDC) motors have many advantages because of their greet characteristics which make them an interested field of research home and abroad. One of the biggest issues which face BLDC motors is the rotor position detection, as they are electrically commutated the rotor position must be detected with or without sensors. The position detection is used for commutation, speed measurement and speed control. The traditional method for BLDC motor rotor position detection which depends on Hall sensors has lots of problems that decrease the system reliability, so sensorless BLDC motor drives are extensively used. The sensorless position detection …

The Psychology Of Patent Protection, Stephanie Plamondon Bair

Faculty Scholarship

This Article offers the first comprehensive assessment of the major justifications for our patent system using a behavioral psychology framework. Applying insights from the behavioral literature that I argue more accurately account for the realities of human action than previous analytical tools, I critically evaluate each of the major justifications for patents — incentive theory, disclosure theory, prospect theory, commercialization theory, patent racing theory, and non-utilitarian theories. I ask whether our current patent system is an effective regime for meeting the stated goals of these accounts. When the answer to this question is no, I again turn to the behavioral …

Differences In Literacy Scores Among Students Who Attended School-Based Prekindergarten, Head Start, And No Prekindergarten, Melissa Hughes

Doctoral Dissertations and Projects

With no state-funded prekindergarten program in Mississippi, some school districts have chosen to divert Title I funds to the creation of school-based prekindergarten programs. This study looked at archival data to determine differences in the beginning of the year kindergarten scores between students who attended local Head Start programs (n = 41), students who attended school-based prekindergarten programs (n = 64) in schools that use Title-I funds to support such programs, and students who did not attend prekindergarten (n = 31). The study sought to examine the question of whether a difference existed in the overall scaled score of the …

A Comparison Of Two Function-Based Interventions: Ncr Vs. Dro In A Preschool Classroom, Zachary C. Labrot

Master's Theses

The purpose of this study was to determine the relative efficacy of non-contingent reinforcement (NCR) and differential reinforcement of other behavior (DRO) after behavioral functions have been identified through indirect, descriptive, and experimental assessment. Participants included three preschool-age children in center-based classrooms (Head Start) in a southeastern school district. Functional assessment data were used to inform treatment procedures, which were examined with an alternating treatments design. This study examined (1) relative differences in the efficacy of NCR and DRO in decreasing problem behaviors in preschool children, (2) relative differences in the efficacy of NCR and DRO in increasing appropriate behavior, …

An Integrated Drought Index (Idi) Incorporating Physical And Social Aspects, Rebecca L. Lanier

Master's Theses

The purpose of this research was to determine significant bio-physical (physical and environmental) and social variables that can be integrated into a drought index to predict areas susceptible to drought. Severe drought events are capable of causing millions of dollars in damage. The 1988 drought caused the United States approximately $40 billion in damage. Drought forecasting, modeling, and detection have, therefore, become imperative to understand the social, economic and environmental impacts of droughts, and also to explore how these impacts play a role in the occurrence of a drought. A number of drought indices widely used in the U.S. rely …

Achieving Relationships, Frederick C. Melancon

Master's Theses

These stories attempt to follow John Gardner’s instruction to create a dream that will engage the reader. Mirroring the goal that an author has to create a relationship with his audience, each story in turn focuses on emotional details that convey the characters’ feelings of isolation or, alternatively, inclusion in their communities. In the first story, a young man tries to recreate his father’s king cake. In the next, a middle school girl fixates on her relationship with her sister. Trying to recapture the memory of a lost daughter, a man searches for the perfect nectar snowball. A mom, then, …

Paleopathology At The Shady Grove Site (22qu525): A Study Of Health In The Upper Yazoo Basin During The Middle Mississippian Period, Christopher Brady Davis

Master's Theses

The Mississippian Period (AD 1000-1539) is characterized by increasingly sedentary populations, mound building, ranked societies, and intensified agriculture. As agriculture spread throughout the Eastern Woodlands, it led to widespread health consequences, including poor nutrition and increased levels of infection. Also, environmental shifts during the Mississippian Period (AD 1000-1539) caused drier conditions, potentially leading to crop failures further exacerbating nutritional problems.

This thesis focuses on the health of the Shady Grove site in the Upper Yazoo Basin, a Middle to Late Mississippian medium sized mound center where an ossuary containing up to 100 individuals was excavated in 2010. Focusing only on …

Development And Validation Of A Survey Of Knowledge Of Autism Spectrum Disorder, Laura Katherine Hansen

Master's Theses

As autism spectrum disorder (ASD) is more commonly diagnosed, having knowledge of the disorder becomes increasingly important for educators, parents, and the general public. Previous research regarding knowledge of ASD, focused mainly on knowledge possessed by those in the educational field, has found that individuals may perceive themselves as possessing average knowledge regarding ASD but have low actual knowledge (as defined by the researchers) regarding specific aspects of the disorder (Williams et al., 2011). Studies support the notion that there is a general lack of knowledge of different aspects of ASD among teachers; however, there has been little research regarding …

A Platform For Fast Detection Of Let-7 Micro Rna Using Polyaniline Fluorescence And Image Analysis Techniques, Partha P. Sengupta

Master's Theses

The project describes a new strategy for transducing hybridization events through modulating intrinsic properties of the electroconductive polymer polyaniline (PANI). When DNA based probes electrostatically interact with PANI, its fluorescence properties are increased, a phenomenon that can be enhanced by UV irradiation. Hybridization of target nucleic acids results in dissociation of probes causing PANI fluorescence to return to basal levels. By monitoring restoration of base PANI fluorescence as little as 10^-11 M (10 pM) of target oligonucleotides could be detected within 15 minutes of hybridization. Detection of complementary oligos was specific, with introduction of a single mismatch failing to …

Bioarchaeological Analysis Of Oak View Landing (40dr1): An Archaic Population In The Kentucky Lake Reservior, Katy D. Grant-Mclemore

Master's Theses

The biocultural examination of the Archaic population recovered at Oak View Landing (40DR1) investigates the lifeways and adaptations of prehistoric people as they reflect sociopolitical and subsistence strategies.

A comprehensive bioarchaeological analysis was conducted on the adult individuals (18 males, 16 females, 16 of indeterminate sex) excavated from a multiple occupation site located along the Tennessee River in Decatur County, Tennessee. Skeletal indicators used to understand biocultural phenomena were assessed macroscopically on cranial and postcranial elements. Furthermore, mortuary data, for adults and subadults, were used to determine any patterns of preferential treatment at death.

Results from this study indicate that …

Staging Sex Or Fighting Foreignness? Marlowe's Edward Ii As Xenophobic Drama, James D. Baker

Master's Theses

Christopher Marlowe’s drama Edward II has long been known for its representation of a close male, arguably homosexual, friendship between King Edward II and his favorite, the French Piers Gaveston, as well as their union’s negative effects on the court. Indeed much criticism exists on the common belief that the characters’ relationship is problematic in early modern England both because the two characters are male and because there is an obvious class divide. However, critics have seemed to overlook Gaveston’s being French, even in light of the massive immigration to England during the late sixteenth and early seventeenth centuries. This …

Effects Of Failure On Subsequent Performance In The Bottlenose Dolphin (Tursiops Truncatus), Lisa Kay Lauderdale

Master's Theses

The current study examined the immediate effects of two types of failure during operant-conditioning based training sessions in 11 bottlenose dolphins (Tursiops truncatus) at the U.S. Navy Marine Mammal Program in San Diego, CA. While learning a multi-faceted behavior not commonly found in nature, such as beaching, animals are likely to perform approximations of the behavior that are not successful and do not result in reinforcement. The effects of failure on beaching trials were systematically investigated over a three-month period by determining the mean failure rate and the probability of success after initial success, initial attempts, and initial …

The overall goal of this project is to investigate Mississippi’s rural food environment by assessing the food resources available to rural Mississippians. The primary objectives were to identify sample locations in each of the four cultural regions of Mississippi and determine the food resources available to residents of those counties. The intellectual merit of this research lies in its in-depth exploration of food accessibility in rural areas. Though there is a wealth of literature on the topics of urban food access and food deserts, very little research has been done in rural areas. Most studies focus on urban environments which …

Management Strategy Evaluation For The Atlantic Surfclam, Spisula Solidissima, Using A Fisheries Economics Model, Kelsey M. Kuykendall

Master's Theses

The Atlantic surfclam, Spisula solidissima, is an economically valuable bivalve harvested along the northeastern United States. The surfclam’s range has contracted and the center of the stock’s distribution has shifted north driven by warmer bottom water temperatures. Declining landings per unit effort (LPUE) in the Mid-Atlantic Bight (MAB) is one result. Declining stock abundance and LPUE suggest that overfishing may be occurring off New Jersey. The objective of this project is to perform a management strategy evaluation (MSE) for Spisula solidissima. The terminal goal is to identify a preferred management option that promotes enhanced surfclam productivity in the …

High Resolution Melt Analysis Of Samples With Differential Dna Methylation To Identify Tissue Source Of Origin, Stephanie M. Ledgerwood

Master's Theses

In Forensic Science casework, identifying the source of a tissue can assist in crime scene reconstruction. Currently, presumptive testing methods to identify tissue type are utilized in crime scene laboratories, but there is a need for a more reliable confirmatory test for tissue type identification. High Resolution Melt (HRM) analysis is an innovative technology that has the potential to determine tissue types through variations in DNA methylation patterns. Recently, DNA methylation patterns have been found to correspond with specific tissue types in particular regions of DNA. Two markers, B_SPTB_03 and DDX4 have been effective in differentiating sperm from other tissue …

Recreation Ecology Of Colorado Fourteeners: An Assessment Of Trail Usage And Impacts, James C. Ewing

Master's Theses

The popularity of climbing Colorado’s 14,000 ft. peaks, or “Fourteeners”, has risen dramatically in recent years, raising important sustainability and management questions. Moreover, groups managing the peaks operate with major capital constraints so their efforts need to be informed, prioritized, and efficient. This paper gauges the dynamics of trail usage, explanatory variables, and recreational impacts across all 58 Fourteeners, and details evaluation adjustments that minimize error and produce results in-step with the resource management framework. Relative to a baseline study completed in 2005, substantial changes occurred in trail usage and impact dynamics. The greatest changes were concentrated on peaks previously …

Territorial Defense Strategies In The Northern Cardinal (Cardinalis Cardinalis): Who Is The Bigger Threat?, Kaylee M. Gentry

Master's Theses

This thesis examines the use of defensive strategies in relation to territories year round in the northern cardinal (Cardinalis cardinalis). Responses to recorded neighbor song and stranger song playback from the middle of a focal male’s territory were measured. This allowed for an estimation of aggression in both the winter and spring seasons. Each focal male was subjected to both treatments (stranger song and neighbor song). Males were more responsive over-all to neighbor song playback, however in the winter months, persistence of response to neighbor song playback increased. It was also shown that southeastern United States cardinals show …
