Full textAbstract:
In this dissertation, I use Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) to study the structure and energetics of gas phase ions. Infrared multiphoton dissociation spectroscopy (IRMPD) is a technique for measuring the IR spectrum of gas phase ions in a Penning trap. I use this technique to investigate the conformation of cucurbituril complexes, terminal diamines, and protonated amino acids. Cross sectional areas by Fourier transform ion cyclotron resonance mass spectrometry (CRAFTI) is a technique developed by the Dearden lab to measure the cross section of gas phase ions. In this work, I further develop a fundamental understanding of this technique. I investigate the role that dissociation plays in this and other FTICR-MS techniques. I also show that the principles of the CRAFTI technique can be used to measure the pressure inside the cell of an FTICR-MS. This technique, linewidth pressure measurement (LIPS), allows for a quantitative measurement and comparison of CRAFTI cross sections. To demonstrate the improvements to the technique, I measure the CRAFTI cross sections for the 20 standard amino acids and compare these to literature values measured by ion mobility measurements.

Full textAbstract:
This dissertation investigates Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) based techniques to study the impact of molecular structure on conformation and binding energetics. A novel method to determine collison cross sectional areas using FTICR (CRAFTI), initially developed by the Dearden lab, was applied to study the conformations of molecular systems with unique structural attributes in an attempt to explore the molecular range of CRAFTI. The systems chosen for CRAFTI studies include crown-ether alkylammonium complexes and biogenic amino acids. The results were found to be consistent with expected behavior, and strongly correlated with experimental measurements made using ion mobility spectrometry (IMS) and predictions from computations. The analytical sensitivity of CRAFTI was highlighted by its ability to distinguish the normal and branched structural isomers of butylamine. Besides conformation characterization, quantitative evaluation of binding was undertaken on metal ion-cryptand complexes on the FTICR instrument using sustained off-resonance irradiation-collision-induced dissociation (SORI CID) method. Complex formation and dissociation was found to be a strong function of both guest and host sizes which impacted steric selectivity, and polarizability. The results demonstrate the ability of FTICR to simultaneously determine structure, conformation and binding thereby providing comprehensive molecular characterization.

Full textAbstract:
In my dissertation, I use a Fourier Transform Ion Cyclotron Resonance Mass Spectrometer (FTICR-MS) to investigate supramolecules. Cross-sectional areas by Fourier transform ICR (CRAFTI), a novel technique for measurements of collision cross sections by FTICR, is demonstrated for the first time. The CRAFTI method measures the total "dephasing cross section" for removal of the ions from the coherent packet in the FTICR cell, including contributions not only from momentum transfer but also from reactive collisions including those leading to collisional dissociation. Experimental CRAFTI collision cross sections correlate linearly with theoretically computed results and with results obtained using ion mobility measurements. Different collision gases, including Xe, N2, Ar, and SF6, are all appropriate for the CRAFTI technique when the experiments are done at proper kinetic energies. The CRAFTI technique was applied to characterize the molecular shape of complexes of alkyl mono- and n-alkyldiamine with cucurbit[n]uril in the gas phase. The CRAFTI results are consistent with corresponding computational geometries. The CRAFTI technique was combined with SORI-CID (sustained off-resonance irradiation collision induced dissociation) for characterization of complexes of α,ω-alkyldiammonium with cucurbit[n]urils (n=5, 7 and 8) and cucurbituril derivatives. The results demonstrate that for bigger cucurbiturils, the complexes have the alkyldiamine tails threaded through the cavity of the host; for smaller cucurbiturils, the complexes have the tails of the alklydiamines external to the portal of the host.Capping molecules for larger CBn to form larger containers were also investigated. Using SORI-CID methods, CB7, a bigger cucurbituril cage, was found to form a more stable complex with Gu+ (guanidinium). Several neutral guests (benzene, fluorobenzene and toluene) were trapped in CB7 cavity to form inclusion complexes.

Singleton, Benedict. "On craft and being crafty." Thesis, Northumbria University, 2014. http://nrl.northumbria.ac.uk/21414/.
Full textAbstract:
This thesis explores how designers might approach human behaviour as a material to be worked on. Unlike politicians, economists, lawyers, philosophers, psychiatrists and many others, designers have few disciplinary resources to draw on in this space. Indeed, it is barely discussed at all. Contemporary designers are, we are told, supposed to treat people and things differently, and ensure that the latter are subservient to the agendas of the former - calls that become all the more insistent when designers are looking for ways to incorporate the design of services and organisations into their practice, a project that summons the prospect of breaking this taboo. But what would a form of design that took human behaviour as its object actually be like? This thesis takes up this question as an issue in the philosophy of design, through investigating a long and rich history of suspicions about designers - namely, suspicions that they might extend their material palette from dead materials to living human beings. This exploration uncovers the emergence in the Industrial Revolution of today’s fears that designers might ‘treat people like things’; but it also uncovers an older, almost lost history of ideas about design, which understood its applicability to human beings in a way that, today, is strikingly unfamiliar. Here we find the almost forgotten but still-lingering link between craft and being crafty, encapsulated well by the lost ancient Greek concept of mêtis, 'cunning intelligence'. Mêtis isolates that aspect of design at work when extraordinary effects are elicited from unpromising materials, connecting design to political intrigues, daring military stratagems, the operations of impresarios and salesmen, and other instances wherein, through ingenious means, the weak prevail over the strong. By uncovering and developing these ideas, the thesis provides a view of design that connects it to human behaviour not through domination but through clever manipulation, a morally complex but undoubtedly potent approach that informs an alternative conception of how human behaviour might be understood as the object of design. The principle contribution of this thesis is, therefore, to provide a novel examination of human behaviour as the object of design; its main achievement is to provide the design disciplines with, on the one hand, an exposition of the implicit associations this project has at present; and on the other, the disinterment of mêtis and related ideas as a promising counter-perspective.

The following report examines the craft beer industry as a major component of the beverage production cluster in Northern Colorado. By using the four locational determinants derived by Porter (1990) as a framework, this study evaluates the role of geography as a key component in an industry’s ability to foster a competitive advantage. Despite his focus on national competitiveness, Porter's diamond model has influenced strategic thinking on a regional scale (Stimson, Stough & Roberts, 2006). In turn, it can help us to understand the interactions that underlie localized cluster dynamics. The cluster conception in economic development literature assumes that each of Porter's components is equally spatially connected. Resources are focused towards building assets in a region defined by analyzing the cluster. However, factors of the craft beer industry in Northern Colorado did not completely adhere to the traditional parameters of regional cluster geography. Personal interviews with key actors involved in the craft beer industry, along with economic data revealed that local factors are not always the driving force behind the development of the craft beer industry. In addition, the data analysis indicates that determinants of cluster success may be significant at various geographic scales. Locational determinants may not operate within the same area as defined by cluster analysis. Thus, this report closes with a recommendation to consider the significance of proximity when looking to increase the competitiveness of a given industry cluster—for the relationship between locational determinants and geography varies between factors.

Full textAbstract:
Museum collections contain examples of Aboriginal Northwest Coast material culture that have been categorised as curios, artefacts, tourist art, arts and crafts, or art. This dissertation examines the emergence of Native Northwest Coast Aboriginal objects made for sale as "arts and crafts". The discussion draws on the multidisciplinary field of material culture studies, on the theories of commodification and on the concept of the reinvention of culture. At the end of the nineteenth century the British Arts and Crafts Movement called for a return to the values and practices of an earlier period of hand crafted objects. For the next half-century in North America government agents, missionaries and philanthropic societies encouraged the production of traditional Aboriginal functional objects as a form of arts and crafts. This activity was perceived as a means of economic self-sufficiency, and to promote feelings of self-identity and self-worth among Native producers. At the onset of World War II. various individuals, private organisations, and government departments worked to transform the producer and the marketplace through education and public policy. Change was to be accomplished by establishing new venues, new expectations of behaviour, and a new social relationship between the supplier and the consumer. Today, a growing number of Native studio crafts people create objects of traditional material culture as a means of livelihood, and as participants in the revitalisation of Northwest Coast Aboriginal society. The term arts and crafts, however, has fallen into disuse and disfavour among Western scholars and Indigenous producers who associate the phrase with poor quality and low income. The term of choice today is art and artist. This work suggests that the production of arts and crafts in British Columbia was an important transition stage in the development of the Native art market. The efforts by private individuals, philanthropic societies and government programs during the mid-20th century raised the value of the hand crafted object. The thesis also suggests that the concept inherent in the Arts and Crafts Movement of "doing good when doing craft", is cyclical, reappearing as strategic policy during times of economic and social crisis on the Northwest Coast.

Cutler, J. E. "Crafting Minoanisation : textiles, crafts production and social dynamics in the Bronze Age southern Aegean." Thesis, University College London (University of London), 2011. http://discovery.ucl.ac.uk/1335717/.
Full textAbstract:
The mid second millennium BC material record of the southern Aegean shows evidence of strong Cretan influence. This phenomenon has traditionally been seen in terms of ‘Minoanisation’, but the nature and degree of Cretan influence, and the process/processes by which it was spread and adopted, have been widely debated. This thesis addresses the question of ‘Minoanisation’ through a study of the adoption of Cretan technologies in the wider southern Aegean: principally, weaving technology. By the early Late Bronze Age, Cretan-style discoid loom weights had appeared at a number of settlements across the southern Aegean. In most cases, this represents not only the adoption of a particular type of loom weight, but also the introduction of a new weaving technology: the use of the warp-weighted loom. The evidence for, and the implications of, the adoption of this new technology is examined. Drawing upon recent advances in textile experimental archaeology, the types of textiles that are likely to have been produced at a range of sites both on Crete itself and in the wider southern Aegean are discussed, and the likely nature and scale of textile production at the various settlements is assessed. A consideration of the evidence for the timing and extent of the adoption of Cretan weaving technology in the light of additional evidence for the adoption of other Cretan technologies is used to gain insight into the potential social and economic strategies engaged in by various groups across the southern Aegean, as well as the motivations that may have driven the adoption and adaptation of Cretan cultural traits and accompanying behaviours. By examining how technological skills and techniques are learned and considering possible mechanisms for the transmission of such technical knowledge and know-how, new perspectives can be proposed concerning the processes through which Cretan techniques were taken up and imitated abroad.

Full textAbstract:
This thesis studies the intersection of crafts and feminism in the Swedish context by focusing on two events organized in Stockholm in the spring of 2018: a feminist market and a #MeToo tagging event. The thesis focuses on the relationship between crafts and contemporary feminism in the Swedish context, in particular how feminism is expressed and done through crafts as well as what kind of feminism is expressed and whom it can be said to represent. Moreover, the thesis explores possible connections between Swedish feminist crafting and activism. Based on field notes from the two events as well as recorded material from six interviews with seven women from the two events, this thesis suggests that there exists a feminist crafts movement in the Swedish context. Moreover, this thesis shows that there are many ways in which crafts may be feminist, such as when crafts are used to convey explicit feminist statements, when they are placed in public or when they empower women. The kind of feminism expressed through crafts has women as its subject, though without specifying if this includes all women or only certain kinds of women. As demonstrated by the visitors and exhibitors at the feminist market and the tagging event, this feminism seems to mainly attract white, middle-class women and feminists. The question of whether feminist crafts in general, and these two events in particular, are connected to activism cannot be easily determined and it is thus argued that what is of importance is not if these two events can be labeled as activist, but rather if they can be understood as events that make a difference. As a result, this thesis suggests that feminist crafts reflect a broader Swedish feminist discourse that, despite acknowledging the importance of intersectionality, fails to analyze how sex/gender intersect with ethnicity and race. A critical discussion is thus needed within the feminist crafting community where the issue of homogeneity within the community is prioritized. More specifically, this thesis suggests that the community ask itself how it can change, and what actions could be taken in order to make feminist crafts more attractive to a wider group of feminists. Likewise, they should also reflect on the underlying factors as to why this community is homogenous and why it fails to attract a more diverse crowd of feminists.Denna studie undersöker intersektionen mellan hantverk och feminism i den svenska kontexten genom att fokusera på två evenemang som organiserades i Stockholm under våren 2018: en feministisk marknad och en #MeToo taggning. Uppsatsen fokuserar på relationen mellan hantverk och samtida feminism i den svenska kontexten, framförallt i form av hur feminism uttrycks och görs genom hantverk liksom vilken typ av feminism som uttrycks och vem den kan sägas representera. Dessutom utforskar uppsatsen möjliga kopplingar mellan svenskt feministiskt hantverkande och aktivism. Baserat på fältanteckningar från de två eventen liksom inspelat material från sex intervjuer med sju kvinnor från de två evenemangen så föreslår denna uppsats att det existerar en feministisk hantverksrörelse i den svenska kontexten. Dessutom visar uppsatsen att hantverk kan vara feministiskt på många olika sätt, så som när hantverk används för att förmedla explicita feministiska åsikter, när de tar plats i offentligheten eller när de stärker kvinnor. Den typ av feminism som uttrycks genom hantverk har kvinnor som sitt subjekt, dock utan att specificera om detta inkluderar alla kvinnor eller endast vissa grupper av kvinnor. Besökarna och utställarna vid den feministiska marknaden och taggningen visar att denna typ av feminism främst attraherar vita medelklasskvinnor och -feminister. Frågan om huruvida feministiskt hantverkande i allmänhet, och dessa två evenemang i synnerhet, är kopplade till aktivism kan inte besvaras enkelt och därför argumenterar uppsatsen för att det är viktigare att fokusera på om dessa två evenemang kan sägas göra skillnad snarare än om de kan tillskrivas en form av aktivistetikett. Som sitt resultat så föreslår denna uppsats att feministiskt hantverkande reflekterar en bredare svensk feministisk diskurs som misslyckas med att analysera hur kön/genus är sammanflätat med etnicitet och ras, trots att den erkänner vikten av intersektionellt tänkande. En kritisk diskussion inom den feministiska hantverksrörelsen är därför nödvändig, där frågan om rörelsens homogenitet bör prioriteras. Mer specifikt så föreslår denna uppsats att rörelsen bör fråga sig själv hur den kan förändras och vilka åtgärder som kan tas för att göra feministiskt hantverkande attraktivt för en bredare grupp av feminister. På samma sätt bör den feministiska hantverksrörelsen också reflektera kring underliggande faktorer till varför den egna rörelsen är homogen och varför den misslyckas med att attrahera en mer mångfaldig grupp av feminister.

Full textAbstract:
This dissertation demonstrates that Sarah Orne Jewett’s The Country of the Pointed Firs (1896), Mary Hunter Austin’s The Land of Little Rain (1906), Kate Chopin’s The Awakening (1899), and Mary Wilkins Freemans The Portion of Labor (1903) exemplify the radical politics and aesthetics that late nineteenth-century literary regionalism shares with the Arts and Crafts Movement. Despite considerable feminist critical accomplishments, scholarship on regionalism has yet to relate its rural folkways, feminine aesthetics, and anti-urban stance to similar ideals in the Arts and Crafts Movement. Jewett, Austin, Chopin, and Freeman all depict the challenges of the regional woman artist in order to oppose the uniformity and conventionality of urban modernity. They were not alone in engaging these concerns: they shared these interests with period feminists, sexual radicals, and advocates of the Arts and Crafts Movement like John Ruskin and William Morris, all of whom deeply questioned industrial capitalism and modernization.
Jewett, Austin, Chopin, and Freeman envisioned women’s Arts and Crafts communities that appealed to readers through narratives that detailed the potential uniqueness of homemade decorative arts and other aspects of women’s material culture. For Arts and Crafts advocates and regionalists, handcrafted goods made using local folk methods and natural materials fulfilled what they saw as the aesthetic requirements for artistic self-definition: The Country of the Pointed Firs and The Land of Little Rain embrace the destabilizing effect queer and feminist characters have on a presumably heterosexual domestic environment, and they formally resist the narrative structures of industrial modernity, emphasizing the Arts and Crafts ideal union between woman artist, natural environment, and communal bonds. The Awakening and The Portion of Labor expose the suffocating impact of industrial capitalism and sexism on women artists who strive for connection with their local environments and communities and cannot achieve their creative goals. I prove that all four texts do more than simply interpret regionalism through the Arts and Crafts Movement as a means to launch their critiques of industrial modernity, they transform the meaning of regionalist Arts and Crafts aesthetics and politics in late nineteenth-century American literature.

Full textAbstract:
Craft beer as a cultural phenomenon coincided with the revitalization of downtown Denton, Texas. Much of the existing literature on craft beer and its relation to place focuses on breweries rather than bars. This exploratory study aims to explain why people consume craft beer, what factors influenced its popularity in Denton despite little beer production, and to explore considerations for the promotion of Denton as a craft beer destination and making downtown an inclusive space. Data was collected through interviews, participant observation, and a survey. Findings indicated that craft beer consumption in Denton is largely related to perceptions of community, localism, and knowledge seeking. The ethos of the craft beer industry closely aligned with participants' perceptions of Denton as a city.

Full textAbstract:
The focus of this dissertation aims to bring about a dialogue between craft and design by using interior architecture as design medium. The study will investigate how craft can be implemented in space, in the form of products and as a part of place-making, in order for it to be elevated to the status of design. The roles of the producer and the user are of particular focus and are the means by which this re-establishment of craft’s identity, previously prey to local and global perceptions, will take place. An intervention that enables a productive work ethic is envisioned, to help contextualise a product effectively in order for it to reach its full potential. This concern for craft can raise awareness of local and global trends in its innovation and encourage the continuous integration of various creative fields. Furthermore, the investigation anticipates a redefinition of the term, commonly associated with souvenirs or curios, into an entity that harbours independence: an attribute that many designed products have. A vacant building in the Pretoria CBD is home to this crafts centre and its refurbishment aims at addressing the needs of those within the creative fields, as well as the general public. This Pretoria regionalist building from the 1960s poses an opportunity in terms of its materiality and its interior, comprising only a column grid. Thus a design opportunity arises in the form of vertical planes as infill, light entry and pedestrian movement, allowing surfaces and details to illustrate craft’s potential within the built environment. The value in the Modern facade is considered to a great extent in terms of retention, whereas the interior allows for a bolder intervention.Dissertation (MInt(Prof))--University of Pretoria, 2011.

Includes bibliographical references.In recent years South Africa has seen the formation of a nascent craft beer industry, with scores of small, independently owned breweries appearing in all corners of the country. Given this growth this descriptive study aims to provide an account of the marketing strategies used within the industry. This study used method and data triangulation, involving both qualitative and quantitative research approaches . Consecutive sampling of all active South African craft breweries was us ed, in order to give a holistic and accurate account (where n=86) . Data was analysed through qualitative content analysis of surveys administered to 24 craft brewers. Furthermore, social media data from the Facebook and Twitter pages of the 86 breweries was analysed quantitatively and through inferential statistics. This aimed at determining whether there were relationships between social media activity and audience size and engagement. The results of this research suggest that craft breweries in South Africa rely heavily on below - the - line and direct marketing tactics. The social media analysis also showed significant positive correlations between brewery -driven activity and audience size as well as engagement.

Quinn, Natalie. "The "Crafting" of Austen: Handicraft, Arts and Crafts, and the Reception of Austen during the Victorian Period." BYU ScholarsArchive, 2011. https://scholarsarchive.byu.edu/etd/2942.
Full textAbstract:
This thesis addresses the significant but often overlooked relationship between Jane Austen's works and the body of criticism about them and the two major craft movements of the nineteenth century: the Handicraft Movement and the Arts and Crafts Movement. The connections occur at two important moments during that century—first, at the moment of Austen's career during the Regency/Romantic period, and second, at the Victorian moment of the years surrounding the 1869 publication of James Edward Austen-Leigh's Memoir about Austen. In both of these moments, critics and reviewers repeatedly respond to Austen's life and works by using craft-related diction. This diction and the coetaneous nature of the craft and critical movements are indicative of the ongoing struggle throughout the nineteenth century to negotiate, eliminate, or redefine the art versus craft aesthetic binary. During the Regency moment, this negotiation begins to emerge in the heyday of the Handicraft Movement and its love for ornamentation. However, it is not until the years surrounding the publication of Austen-Leigh's Memoir that the interdisciplinary ideologies of craft and literary aesthetics burst forth. This period of overlap is short-lived, lasting approximately two decades. Nevertheless, by acknowledging its existence and examining its influence upon the Memoir and the criticism surrounding it, we can gain a greater appreciation for the aesthetic context in which the Memoir was published and for the image of Austen crafted by Victorian reviewers—an image that would ultimately become the literary inheritance of readers and scholars in the twentieth century.

Yair, Karen. "Craft and industry : investigating the nature and value of collaboration between crafts practitioners and manufacturers within the new product development process." Thesis, Sheffield Hallam University, 2001. http://shura.shu.ac.uk/20579/.
Full textAbstract:
The thesis investigates the nature and value of crafts knowledges in the context of the new product development (NPD) process. Its aim is to develop an empirically-derived understanding of the potential benefits for both crafts practitioners and manufacturers of collaborative NPD, and of the factors influencing its outcome. The study adopted a grounded theory methodology, deriving theory from the lived experiences of participants in collaborative projects. Crafts practitioners, crafts-based manufacturers and designers with differing backgrounds and motivations were interviewed in relation to their own perceptions and experiences of the NPD process and its management. From this study, a network of inter-related case studies was developed, enabling comparative evaluation to be undertaken. Data analysis was conducted in relation to an emerging theoretical framework which drew upon an ongoing, critical review of literature relating to theories of design management, cognitive psychology, communication in design, and craft and design epistemologies. The thesis finds that the manufacturers' NPD activities were facilitated by the involvement of crafts practitioners, which resulted in significant intangible gains in addition to successful product outcomes. Collaboration was discovered in exemplary cases to enhance competitiveness, mobilising latent knowledge-based resources and learning capabilities, whilst initiating developments in organisational culture. For the crafts practitioners interviewed, the industrial environment was discovered to offer new affordances and constraints, which could then become a catalyst to creativity. In summary, the research: identifies the impact of crafts knowledges on the NPD process and its intangible outcomes. proposes strategies for the rejuvenation of the crafts-based industries. identifies problems inherent in collaboration and factors influencing project outcome. proposes implications for practitioners, manufacturers, educators and training providers. critiques theoretical advocacy for crafts-industry collaboration.

Full textAbstract:
In recent years, craft fairs, shows and markets where crafters sell their handmade goods such as pottery, jewelry, handmade clothes and needlework have grown in popularity across the United States. A common intent among individuals in this community echo political statements made by the turn of the century Arts and Crafts movement, while there are political aspects of the community that can also be seen as an extension of the third wave feminist do-it-yourself (DIY) ethic of the late 1990s. This newly enlarged community of crafters that congregates in person also has a strong online presence. Etsy.com plays a large role in this community. The introduction of websites such as Etsy.com to the communities they serve has widespread impacts. The aim of this study is to analyze how Etsy.com impacts the lives of women who use the website to earn income. Following ethnographic traditions, the researcher interviewed five community members. The focus was on thick description of the DIY community and thematization of interview narratives. To meet participant observation criteria, the researcher also volunteered at the Independent Publishing Resource Center (IPRC) in Portland, Oregon for 4 months. Additionally, the researcher conducted a textual analysis of blogs, websites, artwork, and other sources of data collected from the online hand crafting community. The study presents and discusses the themes that emerged from the data, including women's work, feminism and technology, the crafters' political statements, the crafters as owners of legitimate businesses, and Etsy.com's impact on local economy. The results paint a picture of the community (both on and offline) and how Etsy.com helps to shape this. The researcher then discusses how to assess the impacts tools such as community websites will have on the communities they serve.

Full textAbstract:
Nowadays, people engage in a diverse range of craft practices in their everyday lives, which take place in physical and digital realms, such as creating decorations for their homes, modifying IKEA furniture, making digital photo collages, or creating their own personal websites. Within this increasingly hybrid age, in which people engage with physical and digital artefacts alongside each other and simultaneously, the research presented in this thesis poses that there are opportunities for new forms of making and creativity at the intersection of physical and digital realms. In other words, it introduces hybrid craft as a new everyday craft practice. Using an interaction design research methodology that consists of research for design (interviewing physical and digital crafters about their current practices) and research through design (designing, prototyping, and evaluating a novel toolkit for hybrid craft, called Materialise), this thesis explores what forms hybrid craft practice may take in everyday life, and what new systems or tools could be designed that facilitate this practice. Employing a comparison of physical and digital craft practices, and findings from design work, design guidelines are formulated for effective combination of physical and digital materials, tools, and techniques, and the realisation of interactive hybrid craft results in interaction design, for example by implementing surprising material behaviour within physical-digital combinations, and by realising techniques to work with physical and digital materials in the same materiality realm. Through empirical and theoretical grounding and reflection, this thesis establishes hybrid craft as a novel concept within design research and craft communities that has a wide range of possibilities in everyday life, both in offering ways to do more with digital media, and in encouraging new forms of making and creativity.

Full textAbstract:
Background: The production of textile crafts requires resources and skilled artisans. In modern times, textile crafts sold in the global market are often made through collaboration involving artisans and profit, social and non-profit enterprises with aim to globalize the aesthetic or styling, structural aspects, and marketability of the crafted product. Collaboration is understood here as two or more enterprises working together towards common profit ideologies, values or goals. Textile craft producer Jordan River Foundation’s (JRF) and IKEA’s Social Entrepreneurship Initiative; collaboration creates home furnishing collections through design and product development, that aim to promote and develop so called local crafts-based economy. Need: In a collaboration, the textile craft producer plays the role of leveraging its resources, and keeps the capability to test its making in the design development and implementation process of craft products. It is thus this need to know of how these collaborative relationships function from a producer’s perspective, emphasizing on the most value adding factor of the design development process. Purpose: The purpose of the study was to investigate and understand primarily from the craft producer Jordan River Foundation’s point of view, the collaborative design development and implementation process with IKEA. Method: The study is a qualitative, narrative, analysing the data and experience from a two-week participatory field study at Jordan River Foundation. Conclusion: As exposed through the collaboration, with IKEA, JRF is challenged with working with cost efficient process of the usage of materials and techniques in design development and methods of craft production, and at the same time maintains its niche as a craft producer. The study concludes that collaborative design efforts in textile crafts, uplifts and enhances, tangible and intangible values. Within the perspective of textile management, the knowledge of collaborative design development in textile crafts interconnects new spaces and turns skill knowledge into a force of competitive advantage for the participating organisations.

Full textAbstract:
The Coulomb propulsion system has no exhaust plume impingement problem with neighboring spacecraft and does not contaminate their sensors because it requires essentially no propellant. It is suitable to close formation control on the order of dozens of meters. The Coulomb forces are internal forces of the formation and they influence all charged spacecraft at the same time. Highly nonlinear and strongly coupled equations of motion of Coulomb formation makes creating a Coulomb control method a challenging task. Instead of positioning all spacecraft, this study investigates having a sensor craft be sequentially controlled using dedicated drone craft. At least three drone craft are required to control a general sensor craft position in the inertial space. However, the singularity of a drone plane occurs when a sensor craft moves across the drone plane. A bang-bang control method with a singularity check can avoid this problem but may lose formation control as the relative distances grow bounded. A bang-coast-bang control method utilizing a reference trajectory profile and drone rest control is introduced to increase the control effectiveness. The spacecraft are assumed to be floating freely in inertial space, an approximation of environments found while underway to other solar system bodies. Numerical simulation results show the feasibility of sensor craft control using Coulomb forces.Master of Science

Sensor device miniaturization and breakthroughs in novel materials are allowing for the placement of technology increasingly close to our physical bodies. However, unlike all other media, the human body is not simply another surface for enhancement - it is the substance of life, one that encompasses the complexity of individual and social identity. The human body is inseparable from the cultural, the social, and the political, yet technologies for placement on the body have often been developed separately from these considerations, with an emphasis on engineering breakthroughs. This dissertation investigates opportunities for cultural interventions in the development of technologies that move beyond wearable clothing and accessories, and that are purposefully designed to be placed directly on the skin surface. How can we design emerging on-body interfaces to reflect existing cultural practices of decorating the body, with the intent to expand the agency of self-expression? This dissertation looks at this question through the development of a series of research artifacts, and the contextualization of a design space for culturally sensitive design. In this dissertation, Body Craft is defined as existing cultural, historical, and fashion-driven practices and rituals associated with body decoration, ornamentation, and modification. As its name implies, Hybrid Body Craft (HBC) is an attempt to hybridize technology with body craft materials, form factors, and application rituals, with the intention of integrating existing cultural practices with new technological functions that have no prior relationships with the human body. With this grounding, HBC seeks to support the generation of future technologized customs in which technology is integrated into culturally meaningful body adornments. The artifacts in this dissertation encompass the integration of technologies such as flexible electronics, chemical processes, and bio-compatible materials into existing Body Craft customs. These artifacts contribute novel, culturally inspired form factors, and introduce unprecedented interaction modalities for on-body technologies. A design space is created in which to examine shifts in the communicative qualities of these Body Crafts due to the integration of technology, as well as new forms of self-expression that have emerged. This dissertation contributes a culturally sensitive lens to the design of on-body technologies. The intention is to expand their lifetimes and purposes beyond mere novelty and into the realms of cultural customs and traditions.

Programing is a singular creative tool with the potential to support personal expression. Unfortunately, many people who are new to programing view it as a highly specialized, difficult and inaccessible skill that is only relevant for career paths in science, engineering, or business fields. Despite this perception, programing enables novel forms of creative expression and communication in the medium of computation. Visual and physical art, craft, and design are interrelated domains that offer exciting possibilities when extended by computation. By forging strong connections between the skill of programming and the construction of personally relevant physical objects, it may be possible to foster meaningful creative experiences in computation and making for non-professionals. The combination of computational design, digital fabrication, and hand craft to create functional artifacts offers an opportunity to make programing compelling for people with an interest in craft sensitive forms of making. I define the synthesis of these fields with the term algorithmic craft. This thesis describes my work in developing a set of software tools that attempt to make the practice of algorithmic craft accessible for novice programers. Through it, I describe the design of each tool and discuss my experiences in engaging people in the creation of objects that are imagined by the mind, designed with programming, formed by machines, and shaped by hand.

A certain amount of care is inferred with the thought of craftsmanship. With a decline in craftsmanship in today’s society, the care and thoughtfulness inherent in the skill of making objects are gradually being replaced by the "ready-made" and the immediate. In order to reverse this trend we must educate the children, teach them the love of craft and making. The children must learn that care and its resultant lasting product are important.
To help preserve the care for making lasting and significant things, I have chosen as my thesis to design a school of craft where children are to gain such knowledge. My hope is to design a space which is expressive of the ideas of craftsmanship using the knowledge of today’s technology.Master of Architecture

This research attempts to identify patterns of successful independent practice among contemporary visual arts practitioners for the purpose of increasing understanding of the structures of and activity within the visual arts in England. The intention is to draw conclusions regarding how such practice can be facilitated and supported. It looks at a particular kind of practice in the area of design craft, and at the organisations charged with the responsibility for state provision, setting this critique in a context of a historical and social perspective. Much of recent conventional practice in the visual arts is considered to have a narrow view of what constitutes acceptable practice and is based on the gallery-based fine arts model. This model is a dubious base line from which to encourage a healthy range of independentpractice, and is of little use to the practitioners in this study, and others of similar intent. The practitioners encountered in this research might beconsidered applied artists, as they have a need to engage with a public during the processes of conception, creation and selling of their work. The patterns have been documented with the assistance of concepts regarding small business, particularly a subsector called micro business. Micro business has recently been identified to describe a pattern of activity which is not conducted for profit or with goals of expansion. The motivation behind micro business is to maintain self determination.

Full textAbstract:
Over the last few decades, the production and consumption of craft beer in the United States has witnessed a spectacular increase. According to the Brewer's Association (2020), there were approximately 89 breweries operating in the United States in 1978 compared to 8,386 in 2019. Along with this rapid market expansion, the cultural status of beer also underwent significant changes. Despite the exponential rise in the number of craft breweries as well as the emergence of a craft beer culture, little empirical scholarship on the field of craft beer exists. In this study, I analyze the rapid status shift of craft beer by exploring its social history of changes that occurred both exogenously to the cultural field of craft beer as well as endogenous developments within the field. Further, I examine in detail the emergence and role of a critical discourse surrounding craft beer culture in relation to its involvement in the elevation of status as well as the construction of symbolic and social boundaries. The theoretical foundation for this study draws on insights from work on cultural fields (Bourdieu 1993), art worlds (Becker 1982), cultural and artistic legitimation (Baumann 2001; 2007a; 2007b; 2011), social and symbolic boundaries (Lamont and Molnar 2002), and the production of culture perspective (Peterson and Anand 2004). Data for this project come both from secondary and original sources including All About Beer magazine and semi-structured face-to-face interviews with craft beer industry professionals. My findings suggest that while the status elevation of the field of craft beer has closely followed those of other legitimized fields (e.g., film), unique discursive and institutional dynamics are also salient. Specifically, I find that through critical discourse, the status elevation of craft beer in the United States context was directly related to a.) the establishment of beer travel as a cultural good, b.) the linkage of craft beer to predominantly white, middle-class leisure activities, c.) the association of beer to other high status gastronomic fields, and d.) the historicization of the field craft beer particularly via the mythologization of early pioneers.Doctor of Philosophy

Drawing on multiple sociological theoretical frameworks I employ a multi-method research design to analyze both secondary and original data to explore questions surrounding the upward status elevation of craft beer from 2002 to 2017 in the United States context. My main findings suggest that through critical discourse, the status elevation of craft beer in the United States context was directly related to a.) the establishment of beer travel as a cultural good, b.) the linkage of craft beer to predominantly white, middle-class leisure activities, c.) the association of beer to other high status gastronomic fields such as wine, and d.) the historicization of the field craft beer particularly via the mythologization of early pioneers.

Chen, Shuling. "Hydrodynamic behaviour of gliding hydrofoil crafts." Thesis, City University London, 2013. http://openaccess.city.ac.uk/2455/.
Full textAbstract:
A new type of high-speed craft, called a Gliding-Hydrofoil Craft (GHC), has recently been developed in Jiangsu University of Science and Technology, China. This craft is similar to a planing hull but with a hydrofoil in the front part of its body. The fixed hydrofoil improves the seakeeping properties and stability of the craft compared with a conventional planing hull. In addition, the GHC has a more simple structure and higher stability when compared to a hydrofoil craft. Unlike conventional planing hulls and hydrofoil crafts, the study of hydrodynamics of GHC has been overlooked. The present work aims to advance our understanding on hydrodynamics of GHC, both model tests and numerical investigations are presented. To study its hydrodynamic characteristics, model tests are carried out in a towing tank, and the total resistance, trim angle and wetted area of the craft in the cases with different Froude numbers are measured. For the purpose of comparison, model tests have also been carried out for the hull without the hydrofoil. This thesis presents analysis on the experimental data and discusses the effects of the submerged depth and initial attack angle of the hydrofoil on the hydrodynamic features of the GHC. On this basis, the FLUENT software is then adopted to numerically investigate the hydrodynamics of the GHC. The accuracy of the FLUENT addressing this problem is validated by comparing the numerical solutions with the experimental data. The validation cases include 2D hydrofoil in current, Wigley hull with steady forward speed. Good agreement between numerical results and experimental data was obtained. Considering the significance of the turbulence involved in the problem, especially near the hydrofoil, a numerical investigation aiming to find a suitable turbulence model has been carried out. After being validated, 3D numerical simulations on both the planing craft and the GHC in steady flow are considered. The resistance coefficient, pressure coefficient and wave pattern with different Froude number are investigated. Some results are compared with experiment data obtained in the model tests. The wave pattern, velocity field and pressure distribution near the hulls are discussed in detail as well as the influence of the hydrofoil. Finally, the hydrodynamic performance of GHC in unsteady flow is investigated. Three cases were considered: ship berthing, leaving the harbour and turning navigation direction; which are very commonly seen unsteady examples in reality. The preliminary results presented in this thesis have confirmed the significant effects due to the unsteady procedure and imply the need of carrying out unsteady simulations in the future.

The work contained in this thesis covers the sulfonylation reaction between toluene and one of methanesulfonic anhydride and methanesulfonyl chloride. The desired products of these reactions are the three isomers (onho. meta and para) of methyl tolyl sulfone and the by-products are methanesulfonic acid, when methanesulfonic anhydride was used as the sulfonylating agent, and hydrogen chloride when methanesulfonyI chloride was the sulfonylating agent. When this reaction was carried out using the traditional Friedel-Crafts catalyst, AlCl) the thermodynamic isomer ratio of 60 % ortlw, 30 % para and 10 % meta was obtained. The aim of this work was to increase the selectivity of the sulfonylation reactions to the para isomer as this was required by the industrial partner (Zeneca) for use in further reactions. The two sulfonylation reactions were carried out over a range of catalysts including Alell , a silica-alumina, a montmorillonite clay and several zeolite catalysts. The main catalyst studied was zeolite Beta as in an empirical test of a range of catalsyts it had given the greatest percentage of para isomer, with a selectivity of 60 per cent obtained under certain conditions. Reaction times, temperatures and stoichiometry were amongst the variables investigated for their role in the reaction. It was found that the reaction had an initial induction period whichever solid-acid catalyst was used, and also that the reaction stopped by twenty four hours, presumably due to catalyst coking. Yields of methyl tolyl sulfone of up to fifty per cent with a selectivity of sixty per cent for the para isomer were obtained using zeolite Beta with some catalysts giving higher yields but correspondingly lower para selectivities. The catalysts were studied using a variety of analytical techniques. The analysis of the catalysts, particularly for a series of well-characterised zeolite Y’s, was compared to the catalysis results and several interesting trends were observed. The Sil Al ratio of catalysts did not have a consistent effect on the yield or selectivity, however the amount of extra› framework aluminium was shown to have a near-linear relationship to the yield. The disproportionate yield in the sulfonylation reaction for zeolite Beta was linked to the ability of zeolite Beta, much investigated recently, to have very mobile aluminiums either in the framework or dislodging from the framework. These act as Lewis acid sites.

Full textAbstract:
This thesis contains new results on the problem of coordinating a group of vehicles. The main motivation driving this work is the development of control laws that steer individual members of a formation, such that desired group behavior emerges. Special attention is paid to analysis of coordination issues, in particular formation control of marine craft where robustness to unknown environmental forces is important. Coordinated control applications for marine craft include: underway replenishment, maintaining a formation for increased safety during travel and instrument resolution, and cooperative transportation. A review of formation control structures is given, together with a discussion of special issues that arise in coordination of independent vehicles.
The main contributions of this thesis may be grouped into two categories:
• Path-following designs for controlling a group of vehicles
• Multi-body motivated formation modeling and control
A previously developed path following design is used to control a group of vehicles by synchronizing the individual path parameters. The path following design is advantageous since the path parameter, i.e., that parameter which determines position along a path, is scalar; hence coordination is achieved with a little amount of real-time communication. The path following design is also extended to the output-feedback case for systems where only parts of the state vector are known. The path following scheme is exploited further in a passivity-based design for coordination where the structural properties render an extended selection of functions for synchronization available. Performance and robustness properties in different operational conditions can be enhanced with a careful selection of these functions. Two designs are presented; a cascaded interconnection where a consensus system provides synchronized path parameters as input to the individual path following systems renders time-varying formations possible and increases robustness to communication problems; a feedback interconnection which is more robust to vehicle failures. Both designs are extended to sampled-data designs where plant and controller dynamics are updated in continuous-time and path parameters are exchanged over a communication network where transmission occurs at discrete intervals. Bias estimation is included to provide integral action against slowlyvarying environmental forces and model uncertainties.
A scheme for formation modeling and control, inspired by analytical mechanics of multi-body systems and Lagrangian multipliers, is proposed. In this approach to formation control, various formation behaviors are determined by imposing constraint functions on group members. Several examples illustrate these formation behaviors. The stabilization scheme presented is made more robust with respect to unknown time-varying disturbances. In addition, the scheme is extended towards adaptive estimation of unknown plant and parameters. Furthermore, it can be applied with no major modifications to the case of position control for a single vehicle.
The formation control scheme is such that it may be used in combination with a set of position control laws for a single vessel, thus enabling the designer to choose from a large class of control laws available in the literature. The input-to-state stability (ISS) framework is utilised to investigate robustness to environmental and communication disturbances. A loop-transform, together with the ISS framework, yields an upper bound on the inter-vessel time delay below which formation stability is maintained.

Common asymmetric weapons such as Anti-Ship Cruise Missiles (ASCM), Low Slow Flying (LSF) aircraft and Fast Attack Craft (FAC) / Fast Inshore Attack Craft (FIAC) threaten U.S. strategic goals and can produce unacceptable losses of men and material. The SEA-18B team presents an operational concept for a family of Unmanned Surface Vessels USV) capable of defending ships from asymmetric swarm attacks. This USV, the Tailorable Remote Unmanned Combat Craft (TRUCC), can operate in concert with the next generation of capital surface vessels to combat this critical threat with maximum efficiency. Critical performance criteria of the TRUCC family were determined through agent-based simulation of a Straits of Hormuz Design Reference Mission. Additional models addressed ship synthesis and operational availability. A Technology and Capability Roadmap outlines areas of interest for investment and development of the next-generation USV. Interim technology and capability milestones in the Roadmap facilitate incremental USV operational capabilities for missions such as logistics, decoy operations and Mine Warfare. The TRUCC operational concept fills a critical vulnerability gap. Its employment will reduce combat risk to our most valuable maritime assets: our ships and our Sailors.

Howarth, Barry. "The craft of Arnold Bennett." Thesis, University of Liverpool, 2016. http://livrepository.liverpool.ac.uk/3001694/.
Full textAbstract:
For the first thirty years of the twentieth century, Arnold Bennett (1867-1931) was one of most famous writers in Great Britain and the United States of America. His stock began to wane after the end of the First World War, and since his death his work has been neglected. What remains of his reputation today rests largely on his achievements in his Five Towns fiction. During his lifetime and posthumously, Bennett was accused of operating as a literary profiteer and vulgar self-promoter. Some of his contemporaries alleged that, as a literary reviewer, he exercised a capricious and excessive influence on the middlebrow reading public. His detractors also suggested that his penchant for writing potboiling serials revealed that he was little more than a commercial servant of magazine and newspaper editors, and of the mass consumerist ideology which they blandly sustained. Most damagingly, his critics came to believe that the quality of his fiction had so declined by the end of the war that he was artistically incapable of embracing the radical challenges of Modernist experimentation. The thesis shows that, as a prolific journalist and perceptive literary critic, his catholic appeal to the reading public was extensive. It also shows that his articles are important for contemporary readers because they sketch out a relief map pointing to the most significant contours of the literary landscape between 1900 and 1930. In addition, the thesis demonstrates that his serials have been injudiciously undervalued. Whilst they were never conceived as high Art, they were important because they helped him to develop as a writer. They provide cogent proof that he always travelled freely along a continuum linking the artist to the craftsman and tradesman. Furthermore, the cultural codes, social values and moral shibboleths which they presciently evoke still resonate in the digital age of the twenty-first century. In his presentation of the enclosed Five Towns communities, the thesis argues that Bennett combined mimetic topography and local culture with deft and complex interpretations of social and private identity. This sophisticated construct allowed him to combine his fidelity to realism with subtle explorations of self-definition. Bennett was not just an accomplished regionalist, and the thesis concludes that he never became stranded as a beached reactionary after the war. His metropolitan novels draw freely upon the interest which he took in the work of Freud and W.H.R. Rivers. They shaped the emergence of his new manner fiction and several of his short stories, allowing him to demonstrate the invalidity of Virginia Woolf's claim that he could not write convincingly and powerfully about human psychology and its susceptibilities to the refracted and sublimated impressions of daily life.
