This thesis explores how gender and sexuality are expressed in southern Manabí Province, Ecuador. The study employs ethnographic methods to recruit local people who identify as LGBTQ (called LGBTI regionally) to participate in interviews on sexuality and gender identity/expression. Based on this research, I explore the construction of “gay” in this part of Ecuador as identity and performance; additionally, reflective viewpoints of those who self-identify as “gay” are thematically incorporated...
Show moreThis thesis explores how gender and sexuality are expressed in southern Manabí Province, Ecuador. The study employs ethnographic methods to recruit local people who identify as LGBTQ (called LGBTI regionally) to participate in interviews on sexuality and gender identity/expression. Based on this research, I explore the construction of “gay” in this part of Ecuador as identity and performance; additionally, reflective viewpoints of those who self-identify as “gay” are thematically incorporated. The term “gay” is used to describe a spectrum of identities that include: homosexual, transformista, travestí, transexual, and transgénero. These identities are not necessarily static, as many individuals traverse categories in a culturally specific progression that I describe. I propose that coastal Ecuadorians utilize a structuring of sexualities and genders within the region that challenges Western LGBTQ+ labels. This research suggests a new regional depiction of non-conforming identities and their manifestations through language, shared strife, communal beliefs, and individual experience.

- THE ZODIACAL CONSTRUCTION OF "TAMBURLAINE I AND II.".

- JEFFERSON, ESTELLE FUGATE., Florida Atlantic University, Collins, Robert A.
- Abstract/Description
-
While the text of Tamburlaine I and II contains the classic pattern of act and scene divisions, the organic structure of the play is governed by the twelve signs and houses of the zodiac. The play's metaphorical patterns are consciously formulated to correspond to the zodiacal year, and consequently represent a circular pattern. The play's well-known rising and falling movement (Parts I and II) is analogous to both solar day and solar year. As hero, Tamburlaine's role is that of Sol, the...
Show moreWhile the text of Tamburlaine I and II contains the classic pattern of act and scene divisions, the organic structure of the play is governed by the twelve signs and houses of the zodiac. The play's metaphorical patterns are consciously formulated to correspond to the zodiacal year, and consequently represent a circular pattern. The play's well-known rising and falling movement (Parts I and II) is analogous to both solar day and solar year. As hero, Tamburlaine's role is that of Sol, the central planet in the Ptolemaic system, ascending with the vernal equinox in Part I and descending with the autumnal equinox in Part II. The imagery traverses, in sequential fashion, the signs and houses, with one radical adjustment: Pisces is removed from the end of the cycle and placed at the beginning of Act I, an alteration which probably has concealed the metaphorical pattern heretofore.

Show moreThe purpose of this study was to investigate the process used by Haitians and Haitian Americans who must make healthcare decisions for a terminally ill family member. There is a large population of Haitians and Haitian Americans in South Florida and there has been no research regarding their decision-making process about end-of-life healthcare. The study design was descriptive, applying constructivist grounded theory methodology. Data were collected using semi-structured, face-to-face qualitative interviews. Data analysis and collection occurred simultaneously. Participants (n=12) were purposefully recruited, with 11 from a single, faith-based community. The findings resulted in six concepts: (1) imminent or actual death, (2) disrupted unity, (3) managing disrupted unity, (4) consequences, (5) restoring unity, and (6) creating memories you can live with. These six concepts, elaborated by an additional 17 dimensions, were incorporated into a process model relating to the cultural value of communal unity to the end-of-life decision-making process. The implications of this study include a need to improve the congruence between the nursing care provided at this vulnerable time and the cultural values of this population. Successful access to this population through the structure of the faith-based community points the way to increasing access to appropriate end-of-life healthcare. Practice implications informed by caring science include the importance of nurses’ coming to know the family and listening to the unique care needs.

Show moreKindergarten, second, and fifth graders were given 15 self-adhesive line drawings to affix on either (1) a simple scene, (2) a scrambled scene, (3) a blank sheet of paper, or (4) a sheet of paper divided into 15 squares. Recall of the objects was tested immediately and again after one week. In general, immediate recall was greater in the simple-scene condition than in all others for all grades tested. Recall in the scrambled condition was also greater than in the other two conditions for second and fifth graders, but not for the kindergarten children. The sheet divided into squares and the blank sheet conditions did not differ from each other at any time. The results for delayed recall were similar in that the condition with the simple scene yielded performance superior to all others. However, the scrambled condition no longer differed from the other two conditions. The results suggest the importance of assessing children's memory for information in conditions or backgrounds which approximate those found in the real world, and of the use of schematic or episodic organization by young children.

Show moreThe purpose of this phenomenological study was to understand, describe, and make meaning of the experiences of early childhood educators of young foster care students. The researcher examined the experiences of teachers regarding the attachment behaviors of their foster care students. This study also sought to explore how early childhood teachers implement their curriculum and how they design their classroom environment to meet the needs of young foster care children. Data collection and analysis included 20 questionnaires and 20 face-to-face semistructured interviews. Data analysis consisted of a three step process. The first step began by reading interviews through a holistic approach. During this step, the researcher read the entire transcript as a whole before digging deeper. The second step in coding was a selective reading. In this step, the researcher read through each transcript by finding key words and/or phrases. The third step in the coding process was a detailed reading. The researcher read the text word-by-word. This step aided the researcher in finding those words that captured the phenomenon of the teachers. The researcher found three major overarching themes: social and emotional behaviors, triad relationship, and classroom accommodations. This study revealed three main themes: attachment-related behaviors of social and emotional development, teacher relationship strategies with student and caregiver, and classroom curricular and environmental adjustments. Within all three of these themes was an underlying theme of a teacher-as-mother perceived attachment from the teachers. The teacher-as-mother perceived attachment was embedded in the experiences of the teachers. It is recommended that this main theme be explored in future research. The experiences of the teachers were completely based on their experiences in this study. The way they intervened on behalf of their foster care students did not appear to relate to any professional development or training; it was entirely based on their experiences. It is recommended that the arena of early childhood would benefit immensely with a course, training, or professional development in learning about the foster care system and dealing with young children in foster care.

Show moreWhile online dating is very convenient, it causes an evolutionary mismatch, our ancestors did not have websites to search for partners. However, there are some similarities that can be seen between current and ancestral times in relation to societal perception, especially in relation to parental investment theory. Using an OkCupid dataset of 2620 questions, 166 were selected in order to evaluate how much of an influence societal perception ( the influence of family and friends, substance use, education, stigma, religion, appearance, and morals) has on searching for a romantic partner. The data was evaluated in four separate stages: Initially just 100 cases were examined to reduce computational burden, then an additional 2000 were used to look at the structure of key variables. Of the remaining cases, 60% were used to develop a prediction model and 40% to test this model. It was found that women tended to be more selective on six of the seven scales that were measured, this selectiveness can be attributed to parental investment theory. significant influence in revolutionary politics through agricultural and industrial collectivization, communes, militia resistance, and participation in government. Many historians have explained anarchism through the lens of ideology, a doctrine based upon a structure of authority. This thesis, however, explains anarchist power and unity during the Spanish Civil War as a matter of identity, as a meaningful sense of self. Spanish anarchists defined themselves through the process of negation – the act of defining who you are by defining what you are not – by their opposition to authority, to religion, to feudalism, to capitalism and fascism, to communism, and to anarchism. The anarchists also affirmed who they were as individuals and as communities through three values: yearning for absolute freedom, the capacity for absolute fraternity removed from centralized authority, and absolute egalitarianism – the unreserved equality of all individuals.

The collection largely focuses on the process of making and preserving memories and how the lack of control over one’s memory can lead to paranoia and displacement in their life. Particular value is attached to certain memories and the value and emotion attached can at times overwrite the actual content of the memory. The stories center around the Riviera family and particularly Ana Riviera’s life as she considers the many aspects of her family history she continues to inherit and the comfort and paranoia she associates with such inheritance.

Any person that goes behind the wheel impaired is at greater risk for hurting themselves or someone else at that time.

Show moreThis dissertation proposes YACAD (Yet Another Congestion Avoidance Design for ATM-based Networks), a congestion prevention model that includes admission control, traffic shaping, and link-by-link flow control for ATM-based networks. Network traffic in this model is composed of real-time traffic and data traffic. As real-time traffic is delay-sensitive and connection-oriented, its call acceptance is based upon the effective bandwidth at all nodes. Effective bandwidth is defined as a vector of bandwidth and maximum node delay. As data traffic can be either connection-oriented or connectionless, it is subject to link-by-link flow control based on a criterion known as effective buffer which is defined as a scalar of buffer size. Data traffic is not delay-sensitive but is loss-sensitive. Traffic shaping is imposed on real-time traffic to ensure a smooth inflow of real-time cells. YACAD also allocates a large buffer (fat bucket) to data traffic to accommodate sudden long bursts of data cells. Absence of data cell loss is a major feature of YACAD. Two simulation studies on the performance of the model are conducted. Analyses of the simulation results show that the proposed congestion avoidance model can achieve congestion-free networking and bounded network delays for real-time traffic at high levels of channel utilization. The maximum buffer requirements for loss-free cell delivery for data traffic, and the cell loss probabilities for real-time traffic are also obtained. In addition, results of performance comparisons to other similar models have shown that YACAD outperforms several other leaky-bucket based congestion control methods in terms of cell loss probability for real-time traffic. The simulation source program has also been verified using existing queueing theories, and the Paired-t Confidence Interval method with satisfactory results at 99% confidence level.

This disparity is reflected in literary and cinematic representations. The Mexican male is the agent that perpetuates the fractured society, and his representation in the arts reflects the impediments to social progress in both the heterosexual and homosexual communities. The novels Los de abajo, Pedro Paramo , and La muerte de Artemio Cruz, present the traditional Mexican male and images of masculinity in the heterosexual community. El vampiro de la Colonia Roma by Luis Zapata introduces the male homosexual character into Mexican discourse and implies how he is affected by fragmentation. The film Y tu mama tambien (2001) by Alfonso Cuaron proposes that inequality will be perpetuated if Mexican society does not change its views of what is to be considered "masculine."

The author uses clustering method to create the system backbone by connecting the cluster heads together and uses color clustering method to create color overlays. Any lookup for a file with a color will only be forwarded in the color overlay with the same color so that the searching space is minimized. Simulations and analysis are also provided in this thesis.

Show moreXYZ Video Compression denotes a video compression algorithm that operates in three dimensions, without the overhead of motion estimation. The smaller overhead of this algorithm as compared to MPEG and other "standards-based" compression algorithms using motion estimation suggests the suitability of this algorithm to real-time applications. The demonstrated results of compression of standard motion video benchmarks suggest that XYZ Video Compression is not only a faster algorithm, but develops superior compression ratios as well. The algorithm is based upon the three-dimensional Discrete Cosine Transform (DCT). Pixels are organized as 8 x 8 x 8 cubes by taking 8 x 8 squares out of 8 consecutive frames. A fast three-dimensional transform is applied to each cube, generating 512 DCT coefficients. The energy-packing property of the DCT concentrates the energy in the cube into few coefficients. The DCT coefficients are quantized to maximize the energy concentration at the expense of introduction of a user-determined level of error. A method of adaptive quantization that generates optimal quantizers based upon statistics gathered for the 8 consecutive frames is described. The sensitivity of the human eye to various DCT coefficients is used to modify the quantizers to create a "visually equivalent" cube with still greater energy concentration. Experiments are described that justify choice of Human Visual System factors to be folded into the quantization step. The quantized coefficients are then encoded into a data stream using a method of entropy coding based upon the statistics of the quantized coefficients. The bitstream generated by entropy coding represents the compressed data of the 8 motion video frames, and typically will be compressed at 50:1 at 5% error. The decoding process is the reverse of the encoding process: the bitstream is decoded to generate blocks of quantized DCT coefficients, the DCT coefficients are dequantized, and the Inverse Discrete Cosine Transform is performed on the cube to recover pixel data suitable for display. The elegance of this technique lies in its simplicity, which lends itself to inexpensive implementation of both encoder and decoder. Finally, real-time implementation of the XYZ Compressor/Decompressor is discussed. Experiments are run to determine the effectiveness of the implementation.

Show moreData are the backbone to any organization. In some organizations there are applications that operate on a distributed platform. These applications might often communicate with applications on a different platform, that structures data in a different format. The manner in which data is transferred between such applications can become complex, because there will be many platform dependent applications that need to process the data transferred. Hence a mechanism for exchange of data in a simple, effective manner for such applications is a basic necessity. In this thesis, such a mechanism to deal with data exchange in a platform independent manner is discussed. The proposed model is XML-based, and data between the applications is exchanged in the form of XML documents. XML is text-based and can be processed by any application existing on any platform. The model has an interface that processes the XML documents transferred between the client applications and the underlying database systems. The model is implemented in a System administration application. The application is a Web application that transfers data in the XML format. This is processed by the interface and transferred to the database. Data from the database is retrieved and converted to XML documents by the interface and transferred to the client (Web) applications.

The problem of the carbonate substitution in bioapatites is studied via x-ray and neutron powder diffraction. A series of samples of low temperature carbonate hydroxyapatites with varying carbonate content was synthesized. The carbonate solubility in the hydroxyapatite system was studied with x-ray diffraction. The detailed crystal structure parameters of the synthetic carbonate hydroxyapatites were studied as a function of temperature and carbonate content from the analysis of Rietveld...
Show moreThe problem of the carbonate substitution in bioapatites is studied via x-ray and neutron powder diffraction. A series of samples of low temperature carbonate hydroxyapatites with varying carbonate content was synthesized. The carbonate solubility in the hydroxyapatite system was studied with x-ray diffraction. The detailed crystal structure parameters of the synthetic carbonate hydroxyapatites were studied as a function of temperature and carbonate content from the analysis of Rietveld refinements of neutron powder diffraction data. The phosphate tetrahedron is distorted by the carbonate substitution. The tetrahedral bond lengths P-O1 and P-O2 decrease by 2--3%. The atomic displacement parameters (ADPs) of the tetrahedral P, O1, O2, and O3 sites reveal a static disorder in the carbonate hydroxyapatite specimens. The results of the present comparison are consistent with the mechanism of carbonate substitution on the mirror plane of the phosphate tetrahedron.
