  • 1. Castele, Daniel Designing Within Historic Guidelines: an American Epidemic

    MARCH, University of Cincinnati, 2019, Design, Architecture, Art and Planning: Architecture

    Architectural intervention on historic properties or within historic districts is often a spirited debate. The appropriateness of a restoration, renovation, or reuse of a building or site has become so integral to the cohesive urban fabric that historic committee have sprang up all over the United States to help govern and restrain new design in interest of preserving a unified historic urban fabric. And while there are countless local committees; whether or not to intervene on historic structures, and exactly what to do, is perhaps the most perplexing and aggravating for modern architects. This thesis aims to tackle such contradictions as “similar but different” within the field of Historic Preservation, by more specifically taking a look at designing within historic contexts. This is significant to the discipline considering the widespread re-urbanization of historic districts that has been seen in every major metropolis across the United States over the past few decades. In some instances, proper intervention has retained the historic character of such neighborhoods and has, as a result, raised property values incredibly; while other instances have, when done poorly, destroyed all authenticity and cultural purity (something that took centuries to build up organically).

  • 2. Roy, Kingkini A Case for Change in Indian Historic Preservation Planning: Re-Evaluating Attitudes toward the Past

    MSARCH, University of Cincinnati, 2011, Design, Architecture, Art and Planning: Architecture

    This thesis critically surveys heritage management in present day India and the legislative apparatus that underpins it. Keeping within the Indian context, the research seeks to verify the suitability of the strategies that are upheld by the institutional and legislative setup of architectural conservation practices for present day India. This appraisal would be based on the premise that preservation, as it is currently understood in India, is a product of modernity and in India's case the direct import of the Western construct of these disciplines during the colonial period. This is made evident from the history and origins of the interest in Indian antiquity as well as the development of the formalized discipline of archaeology and antiquity management. Despite the fact that India has been independent from colonial British rule for sixty one years, the legislation that continue to underpin the heritage management policies of India have remained unrevised for fifty of those years with the exception of a few minor amendments. The current active piece of legislation is in fact a slight variation on the one laid down by the British more than a century ago. Consequently, India's prevalent heritage management policies are not only outdated, but also contextually unsuitable since it originates from a non-indigenous and particularly colonial mode of thinking. The research primarily focuses on the practices of the Archaeological Survey of India (ASI), the formal institution concerned with upholding the legislation concerning heritage. Using case studies the contextual suitability of the prevalent preservation policies have been analyzed through the successes and failures of the ASI in the cases under consideration. The argument is extended to the conceptual notions of time and the past as signified by the current preservation laws and studying them in contrast with alternative approaches to those notions. It is concluded that present day heritage management practices in In (open full item for complete abstract)

  • 3. DE SOLA, MEGAN A REVIEW OF CEMETERY PRESERVATION STRATEGIES IN BOONE COUNTY, KENTUCKY

    MCP, University of Cincinnati, 2002, Design, Architecture, Art, and Planning : Community Planning

    Boone County, Kentucky is located approximately 20 miles southwest of Cincinnati, Ohio. The county, which remained rural for most of the twentieth century, has become, over the past twenty years, the site of new suburban residential, commercial, and industrial development. Unfortunately, the increase in development resulted in a rise in the number of small family cemeteries lost during construction. During the late 1980s, Boone County realized that the destruction of local cemeteries by new development was becoming a problem and was likely to worsen in the future. The county developed a Cemetery Preservation Plan designed to protect existing cemeteries from disturbances during construction projects. The plan was approved and implemented in 1989. This thesis discusses and analyzes the impact of the Boone County Cemetery Preservation Plan, and a similar plan established by Cobb County, Georgia in 1990. A comparative case study of the two plans is conducted. Specifically, the number of disturbed and preserved cemeteries, before and after the implementation of the plans, is reviewed. Furthermore, a careful analysis of the existing plan recommendations is performed. The findings are then compared to cemetery preservation issues in Campbell County, Kentucky, which does not currently have a preservation plan or a preservation zoning ordinance. Based on the case study and the literature review, this thesis finds that both Boone County and Cobb County have had positive impacts on the preservation of their local cemeteries. Both counties have improved their methods of record-keeping and have successfully implemented cemetery protection zoning regulations. However, only Cobb County established a dedicated Cemetery Preservation Commission to manage their preservation efforts. This study finds that a dedicated cemetery preservation organization is needed in order for a county to institute, promote, and accomplish specific preservation goals. The cemetery organization should be g (open full item for complete abstract)

  • 4. Leake, Michael Improving the Learning of Laparoscopic Colon Resection Procedural Skills for General Surgery Residents by Working with Soft-Preserved Donors

    Master of Science, The Ohio State University, 2022, Anatomy

    Under ideal circumstances, surgical skills training should emulate live surgical conditions as closely as possible. While new anatomically accurate models and virtual/augmented reality simulators make surgical anatomical knowledge acquisition more accessible, research shows that these resources are limited in their ability to fully reflect the live human anatomy. As such, the animal and human body donor models have remained the gold standards for surgical simulation. And while there have been studies comparing the porcine and human body donor models, very little is known about Imperial College of London – Soft Preservation (alcohol-preserved) human body donors in the context of surgical training and education. The objective of our study was to examine the alcohol-preservation technique and to further elucidate its utility in general surgery resident education. Utilizing questionnaire-based feedback and semi-structured interviews, we analyzed quantitative and qualitative data obtained from the accounts of general surgery residents and surgical faculty instructors who experienced both the porcine and alcohol-preserved models at The Ohio State University Wexner Medical Center. Results indicated that the porcine and alcohol-preserved human body donor models were preferred for different aspects of surgical training. While the porcine model was preferred for its ability to teach tissue-handling and to simulate live blood flow, the alcohol-preserved human body donor model was unanimously preferred for its anatomical relevance, colon suturing/stapling, and reflection of live operating conditions. Surgical faculty specifically noted that while there is anatomical overlap between the two models with the anatomy of the rectum, “the small bowel and colon are dramatically different, which does not give the full breadth of colon resection needed for the human model.” In addition, the alcohol-preserved model was regarded as superior to the formalin-fixed human body dono (open full item for complete abstract)

  • 5. Lemke, Matthew Polylactic acid (PLA) Membrane as a Sole Treatment For Alveolar Ridge Preservation

    Master of Science, The Ohio State University, 2014, Dentistry

    Abstract Background: The combination of membranes and bone grafting materials has been shown to preserve the post-extraction dimensions of the alveolar ridge and constitutes the currently accepted protocol for socket preservation. However, the use of bone grafting materials in extraction sockets has been questioned because of possible interference with bone formation in the wound sites; particles of graft material have been found in alveolar sockets more than 6 months after placement. Histologic examination of extraction sockets filled with allograft bone revealed the presence of graft particles with no evidence of bone formation on the particle surface, suggesting that the allograft bone may delay healing and affect the quality of regenerated bone. The purpose of this preliminary study is to determine whether use of a polylactic acid (PLA) membrane alone (without bone graft) after tooth extraction results in sufficient bone formation for implant placement and to determine the quality of the newly formed bone. Methods: Patients with single rooted non-esthetic teeth deemed hopeless for various reasons and in need of extraction, socket preservation and implant placement were recruited at the Graduate Periodontology Clinic, College of Dentistry, The Ohio State University. Extraction sites were randomly assigned to either control group (extraction alone) or test group (extraction + PLA membrane). Clinical measurements, including relative ridge height and soft tissue level, were recorded using a pre-fabricated plastic stent before and immediately after extraction, and pre-implant placement. Clinical parameter measurements were recorded at six different positions (MB, B, DB, ML, L, and DL) per extraction site. Bone cores (2 x 6 mm) were retrieved with a trephine immediately before implant placement and subjected to micro-computed tomography (micro-CT) and cone beam CT (CBCT) scans followed by histomorphometric analysis.

  • 6. ZHANG, YING KEEPING OUR PAST: SMALL TOWN PRESERVATION IN AMERICA SINCE 1950

    MS ARCH, University of Cincinnati, 2001, Design, Architecture, Art, and Planning : Architecture

    Although the major focus of the American preservation movement has been in cities, preserving traditional small towns and villages has also been important. An increasing sensitivity to environmental issues has given small town preservation greater support than at any time in its history. However, there is not much research about ideas in small town preservation. The aim of this thesis is to discuss the history and theory of preservation in American small towns since the 1960's, giving a systematic review on this movement. The first part of the paper presents the development of thinking in historic preservation since the 1950's. The idea of preserving the historical and cultural patrimony is not new, but the significance of historic preservation has broadened substantially in past half century. The paper discusses its background and its various forms in order to understand how it has evolved, especially since the passage of the National Historic Preservation Act in 1966. The second part considers the specific issues related to small towns, the special economic, cultural, and architectural issues that affect preservation efforts in communities of less than 20,000 inhabitants. The thesis looks at the American small town and its diverse representations in both highbrow and popular culture from a number of angles, exploring the meaning of the sense of community and the sense of the land in small towns. This study also presents detailed accounts of what two American small towns have accomplished, illustrating why, what and how preservation occurs in specific contexts and circumstances. A concluding section generalizes from the experience of American small town preservation, comparing it to the situation of Chinese traditional towns and villages. As China left the 20th Century behind it saw the beginnings of a "Post-Industrial" movement stimulating economic development and social interest in its smallest towns, villages and hamlets. Despite their small size, these places h (open full item for complete abstract)

  • 7. BANYAS, JEANNE RECONNECTION: INDUSTRIAL WATERFRONTS IN A POST-INDUSTRIAL CITY

    MARCH, University of Cincinnati, 2004, Design, Architecture, Art and Planning : Architecture

    Urban waterfronts developed as areas of intense, industrial use. The water and its edge often became polluted to the point where they were toxic. Cities moved away from this environmental degradation by re-centering inland. After years of thinking of the waterfront as a contaminated, industrial area unfriendly to normal life, highways and other massive pieces of infrastructure were built, decisively separating city and water. Now, through the decentralization of industry, the shift from an industrial to a service economy, and general pressures of globalization, most large-scale industry and shipping has moved away from city centers. This has left behind industrial waterfront sites which are currently seen as areas in which to remake the post-industrial city. In order to create successful waterfront redevelopment projects, it is important to examine and facilitate connections that exist or should exist between the city and the water. The types of connections essential to waterfront development are the connection with the industrial past, the connection with the landscape, and connections within the fragmented city. Re-connection will ultimately lead to richer environments that help to sustain cities both socially and economically. Cleveland, Ohio is a city that typifies the problems of post-industrial cities. Through the exploration of this discussion of connections on a site bordering the Cuyahoga River, it will be possible to create a waterside community that both embraces the past industrial use and supports the struggling city.

  • 8. Salas, Mabel Alveolar Ridge Preservation at different anatomical locations – Clinical and Histological evaluation of treatment outcome

    Master of Science, The Ohio State University, 2009, Dentistry

    Background: Alveolar ridge preservation (ARP) is a surgical technique designed to prevent naturally occurring post-extraction bone resorption.. The purpose of this study was to investigate clinical and histological healing outcomes following ARP performed on molar and premolar sites by using freeze-dried bone allograft (FDBA) together with a collagen membrane. Maxillary and mandibular sextants were compared for clinical and histological parameters. Methods: Inclusion criteria were single tooth extraction with intact mesial and distal adjacent teeth. Exclusion criteria were smokers, patients with ystemic health problems and acute infection. A stent was prepared from clear acrylic. Pre-operative clinical measurements included the amount of keratinized gingiva and clinical attachment level at tooth scheduled for extraction and at adjacent teeth were taken. The thickness of buccal and lingual plate, the length and diameter of the extracted tooth, buccal-lingual and mesial-distal defect size and, the distance from stent in place-occlusal plate to alveolar crest were measured. FDBA and collagen membrane were placed and flap was sutured. A re-entry surgery was performed following approximately 140 days healing period. Clinical measurements were repeated. A bone core was obtained and immediately frozen in liquid nitrogen. Frozen bone cores were analyzed with micro-CT scan for bone volume density and bone trabecular connectivity. Following micro-CT scan, cores were fixed in formalin, decalcified, embedded in paraffin and sectioned. Slides obtained from the mid-portion of the bone core were stained with trichrome and analyzed under light microscopy. Results: Twenty-one patients were completed the study. Following ARP, ridge height loss change was negligible (a loss of 0.4±0.3 mm in maxilla and a gain of 1.3±0.3 mm in mandible). However, average ridge width loss was 2.4±0.8 mm and 2.5±0.5 mm in maxilla and in mandible, respectively. In maxilla, initial CAL at mesial surface of (open full item for complete abstract)

  • 9. Quesada-Embid, Mercedes Dwelling, Walking, Serving: Organic Preservation Along the Camino de Santiago Pilgrimage Landscape

    Ph.D., Antioch University, 2008, Antioch New England: Environmental Studies

    This study is an exploration of the people and the landscape of the well-known Camino de Santiago pilgrimage route. Although there are many routes that make up the entirety of the pilgrimage, this research is specifically focused on the landscape of the Camino Frances, or French Route, in northern Spain. The path has been written about in many ways and for a myriad of reasons since it became affiliated with the Christian tradition in the early ninth century. This research, however, is different. By way of an environmental history and hermeneutic approach, an investigation of the interrelated and overlapping human actions of dwelling, movement, and service that stem from the pilgrimage tradition on the Camino de Santiago is conducted. Unlike other studies of this pilgrimage path, both pilgrim and resident receive equal attention, and the landscape emerges as central to the research. This study provides: an integrated evaluation of the ancient pre-Christian and medieval Christian histories and perceptions of the path; a description of the physical landscape; an in-depth assessment of conventional landscape and cultural heritage strategies for preservation; and a linguistic, social, and philosophical discussion of the correlations among dwelling, walking, serving, and preserving that are apparent on the landscape. Embedded within this examination of the Camino de Santiago landscape is a return to the essence and origin of the ideal of preservation itself. This analysis of landscape preservation is specifically centered on traditionally peopled landscapes and cultural landscapes, i.e., those with a deep history and presence of people. This study proposes that the Camino de Santiago landscape serves as a model for the preservation of tradition, history, culture, and nature. Moreover, it contends that the landscape is an exemplar of what I have termed organic preservation precisely because the people evolved in a reciprocal relationship with each other and the la (open full item for complete abstract)

  • 10. Abdelkader, Nadia MASS SPECTROMETRIC ANALYSIS OF CLINICALLY RELEVANT MOLECULES

    Doctor of Philosophy in Clinical-Bioanalytical Chemistry, Cleveland State University, 2024, College of Arts and Sciences

    Over the past 60 years, mass spectrometry (MS) has emerged as a premier analytical technique for fatty acid (FA) analysis due to its exceptional sensitivity and selectivity. Techniques combining chromatography with MS, such as liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS), have significantly enhanced the accuracy and robustness of FA quantification. Among FA metabolites, polyunsaturated fatty acids (PUFAs), particularly arachidonic acid-derived eicosanoids, play crucial roles in inflammation and disease pathology. Dysregulated eicosanoids are implicated in various diseases, underscoring the need for precise quantification in biological samples. LC-MS is the preferred method for eicosanoid analysis due to their low concentrations in biological matrices. The first part of this dissertation presents the development and validation of an LC-MS/MS method for quantifying 11-dehydrothromboxane B2 (11-DHTXB2) in human urine, a stable metabolite of thromboxane A2. Elevated urinary 11-DHTXB2 levels serve as a robust prognostic biomarker for atherosclerosis progression, offering the potential for monitoring disease progression and evaluating the efficacy of anti-atherogenic therapies. Short-chain fatty acids (SCFAs), produced by bacterial fermentation of undigested dietary components, are vital gut health biomarkers. Alterations in SCFA concentrations reflect gut microbial imbalances and are linked to inflammatory bowel disease (IBD), which arises from genetic, environmental, and microbial factors leading to an aberrant immune response. IBD-associated gut dysbiosis involves a reduction in SCFA-producing bacteria such as Bacteroides, Firmicutes, and Lactobacillus, resulting in significantly altered SCFA levels. GC-MS, widely regarded as the gold standard for analyzing volatile and semi-volatile compounds, excels in SCFA analysis due to its superior separation capabilities.

  • 11. Kang, Yeram Alveolar Socket Preservation Clinical Outcomes: Comparison of Two Surgical Approaches

    Master of Science, The Ohio State University, 2024, Dentistry

    Background and objective: Socket preservation is a bone regeneration procedure indicated immediately following tooth extraction to preserve existing alveolar ridge height and to control alveolar ridge width. Primary wound closure following socket preservation is not indicated since it is a flapless procedure and wound edges cannot be proximated to close the bone graft through suturing. Instead, a collagen plug and/or a resorbable membrane is generally used to stabilize bone graft and seal the orifice of the socket. The purpose of this approach is to allocate time for soft tissue granulation and complete epithelization. To our knowledge the indications for these two types of biomaterials are not well-established and there are no clinical studies in the literature comparing clinical outcomes in relation to the use of these wound management approaches. Thus, the purpose of this study was to evaluate and compare the early clinical outcomes following socket preservation procedures performed by using collagen plug (CP) or collagen membrane (CM) as a sealing material. In addition, soft tissue phenotype was evaluated as a variable possibly affecting clinical healing outcomes. Material and Methods: Patients who need single tooth extraction (surrounded with mesial and distal intact teeth) and socket preservation procedures for a future implant placement procedure were recruited (IRB protocol #2022H0277). Impressions (digital) were obtained prior to surgery and at 3-6 months to study ridge dimensional changes. Soft tissue phenotype was determined prior to extraction by probing and buccal tissue thickness was determined by using a surgical caliper. Buccal bone integrity was determined by probing immediately after extraction. FDBA was used as bone graft material. Decision to use a collagen plug or collagen membrane was clinician's choice based on the case and site anatomy. The membrane and plug were stabilized via simple interrupted and cross matrix suture using a resorbab (open full item for complete abstract)

    Doctor of Philosophy, Case Western Reserve University, 2024, Genetics

    Alzheimer disease (AD) affects more than 6 million individuals in the US, and accounts for 60-80% of dementia cases. AD demonstrates mixed pathologies of amyloid beta and tau tangle accumulation, leading to symptoms such as cognitive impairment and memory loss. Taking advantage of a closed, isolated population, the Midwestern Amish, variants both in protection against AD as well as risk for AD were explored. The comparative reduction in incidence of AD within the Amish versus a general European population led to the examination cognitive preservation, rather than AD, as the diagnosis of interest. A genome-wide association study (GWAS) was performed on the Amish to identify protective loci for AD via the GENESIS R Package. PC-AiR and PC-Relate were used for principal component analysis to assist in correcting for the highly related sample. Linkage analyses across the entire genome, once again for cognitive preservation, were used to supplement and corroborate GWAS findings. These analyses were initially completed in MERLIN, but certain regions demonstrating repeated 16 significance were run through MORGAN, an MCMC linkage analysis software. These analyses highlighted one region on chromosome 2p11.2-13.1 that demonstrated a protective effect against AD. This region was previously associated with risk for AD in the Midwestern Amish, potentially indicating both protective and risk variants within this locus. Further evaluations of genetic loci implicated in AD took advantage of this unique sample population to examine a potential risk factor. The MGMT locus was previously associated with increased risk for AD in the Hutterites, who are another closed, isolated population of European decent. In the Midwestern Amish, one SNP in the MGMT locus was significantly associated with AD diagnosis. However, this SNP was a novel result, distinct from those detected in a previous study and not in linkage disequilibrium with previously associated MGMT SNPs for (open full item for complete abstract)

    Master of Science, University of Akron, 2024, Polymer Science

    Adhesives are commonly used in art restoration, and one of the most essential synthetic adhesives was introduced by Gustav Berger's BEVA in 1970 for relining artworks. For improving low-temperature tackiness, this adhesive formulation is dissolved in toluene and applied onto a relining canvas. However, this process relies on the use of solvents that are not good for health and environmental concerns. My research is focused on reducing the use of toluene and developing water-dispersed formulations. The amount of toluene-water mixture was optimized to prepare stable dispersion with the required adhesive content and the optimum activation temperature required for the relining of the canvas. To enhance the duration of suspension stability, surfactants were added, which increased the shelf-life of the dispersion. The goal of my research was to offer a safer and environmentally friendly method for preserving cultural heritage.

    The development of hybrid organosilicon materials as both rapid curing coatings and photo-responsive sponges has been conducted utilizing silsesquioxane (SQ) based chemistries for the robustness they provide in the final materials. Additional research was conducted on the formation of sulfur-based SQ analogs. Chapter I will provide background about the synthesis of silsesquioxanes, their properties, and the favorability for three-dimensional material formation using these molecules. Additional information will include challenges and histories of siloxane based protective coatings and the use of both photo-radical and photo-acid-generating initiators in them, along with a brief explanation of photo-switches, specifically azobenzene and its derivatives and their use in sol-gels. Chapter II will discuss protective coatings for monuments and the specific needs associated with these materials. A history of the types of materials used and their faults will detail the desire for new materials aimed at this application. The development of a coating with three distinct curing methods (including photo-radical and photo-acid generating processes) which forms a protective layer with a mixture of partially formed polisilsesquioxane and oligosilsesquioxane structures as the backbone of the network. Findings and properties of the resulting coating formulations, modifiability, and alternative functionalities will be discussed in detail. Chapter III will discuss the use of photo-switches as crosslinkers in silicon-based networks. Previous work utilized Q-type silsesquioxanes (Q8M8H) and 4,4'-diallyloxyazobenzene (DAA) to develop photodynamic sponges.

    PHD, Kent State University, 2022, College of Arts and Sciences / Department of Earth Sciences

    This dissertation contains 6 chapters which examine the effects of volcanic ash deposition on paleoenvironment, sedimentology, fossil preservation, and paleoecology. It includes field-based research and experimental data which demonstrate that volcanic ash deposition can play an important role in shaping the nature of the sedimentary and fossil records in marine settings at both distal and proximal localities. Chapters 1 and 2- Summary and introduction. Chapter 3 – This chapter discusses two Cenozoic marginal marine settings which occur proximal (within 100 km) to prominent volcanic centers; one in the Pacific Northwestern United States, and one in the south of the Patagonian Cordillera, Argentina. The Oligocene Lincoln Creek Formation in Washington contains an exceptionally well-preserved marine fauna dominated by crustaceans and mollusks, and the late Miocene-early Oligocene Estancia 25 de Mayo Formation in southern Patagonia, Argentina, contains a similar exceptionally preserved fauna. In both settings, evidence shows that exceptional fossil preservation was facilitated by the deposition of mass quantities of volcanic ash via marine hyperpycnal flows following large volcanic eruptions. Chapter 4 – As discussed in the previous chapter, volcanic sediments can facilitate exceptional fossil preservation. The rapid deposition of fine-grained material in marine settings can preserve fossil material which may otherwise not be preserved. One such example of preservation in volcanic ash is a new species of isopod from the above-described Estancia 25 de Mayo Formation. In this chapter, Cirolana centinelensis n. sp. is described as the first known occurrence of the Isopoda in the fossil record of Argentina. The chapter discusses the recalcitrance of fossil isopods with respect to preservation and elucidates how the rapid deposition of volcanic ash facilitated the preservation of this exceptionally rare fossil specimen.

    MARCH, University of Cincinnati, 2022, Design, Architecture, Art and Planning: Architecture

    Heritage is always at risk when developers and advocates tear down and replace structures for their own profit and commercial purposes. Preserving sites and their history has become more popular and has been gaining a foothold in movements across the world. The appropriation of the intervention on historic sites has become a subject prone to criticism from the polarities of conservative to more liberal heritage conservationists. In Beirut, Lebanon, a city that has been rebuilt several times throughout history and now faces the need of intervention after sustaining severe damages from the 2020 Port Blast, the debate is a sensitive subject. The efforts to rebuild following the Civil War (1975 – 1990) are criticized for the demolition of historic structures and gentrification. What lesson can be learned and applied to the current situation of Beirut and its few remaining heritage structures? This thesis aims to approach the subject of rebuilding after the Port Blast by using methods of adaptive reuse to preserve the history and memories embedded in the structures while bringing new life and purpose to their post-blast conditions.

    MARCH, University of Cincinnati, 2022, Design, Architecture, Art and Planning: Architecture

    In a developing country as India, there is a vast sociocultural gap between Urban and Rural ecosystems. As per the Census 2021, ‘urbanization is spreading, and rural India will be History' soon (Down to Earth,2019). While this might seem like progress at face value, the phenomenon of a predominantly rural community converting to urban spheres is a sign of alarm to the cultural diversity of India. But more importantly, ‘the immediate concern is whether India's farming population will' ‘migrate to nonfarm occupation', posing an obvious question; will food scarcity become more rampant than it is, or can farming be ‘lucrative enough to provide for the survival of its farmers', and the rural community at large. While 74% of India's population is rural people, architecture has done little to reverse this migration force. The thesis proposes Rural Agro-tourism as a solution to reverse the migration flow from rural to urban areas by providing economic opportunities and retaining socio-cultural fabric through the appropriation of threshold spaces using critical regional theory. A threshold is a structural entity that marks the transition from one region to another which facilitates transition, in-betweenness, and is characterized by ambivalence fosters a mix of conditions, people and creates a dynamic nature of space. The paper focuses on developing a design methodology for the concept of swadeshi thresholds where swadeshi means ‘of one's own country'. Swadeshi Thresholds discuss built identity that evokes a sense of place, through the socio-cultural ethos and climatic appropriation which is ignored in many contemporary constructions due to a fascination with Western glass facades. Thresholds will be deconstructed and reconstructed through Till Boettger's framework of threshold analysis. The lack of vocabulary in the framework for describing the location of place-making elements in the threshold is filled by borrowing Ing Kevin lynches framework of places (open full item for complete abstract)

Some in the architectural industry have chosen to address this issue through methods of transformation and adaptive reuse an attempt to preserve and alter previously unpopular, aging identities. By understanding the concepts of value, permanence, obsolescence, and preservation, innovative design solutions can challenge the widespread endangerment of buildings. Brutalism is slowly gaining popularity after a large period of distaste. However, a timely response is needed in order to prevent the end of this controversial, unique, and historical style. In the case for Crosley Tower, a concrete high rise associated with Brutalism, on the University of Cincinnati's campus in Cincinnati, Ohio, demolition is soon approaching. Innovative methods of transformation, preservation, and demolition will alter the structures identity and provide hybridized solutions that challenge its unique existence. A matrix of iterations involving constraints of addition, subtraction, and combinations of both provides a selection of four designs to be iterated on a more detailed level. These four project proposals both meet and challenge the physical and metaphysical nature of Crosley Tower in order to realize potentials hindered by traditional, uninventive demolition.
