The application of capillary electrophoresis to examine protein modifications in baked versus fried tortilla chips
Although lipid oxidation is recognized as a major chemical reaction limiting shelf life of foods, its role in degrading food quality and the mechanisms involved remain incompletely elucidated. Interactions of oxidizing lipids with other food molecules have been largely ignored, even though these reactions can have dramatic impact on food properties. Lipid co-oxidation of proteins occurs extensively in nearly all processed foods and degrades textures, flavors, color, and nutritional value. It is important to measure both lipid and protein co-oxidation products to understand the full extent of oxidative deterioration during food storage. This thesis is part of a larger project examining baked and fried tortilla chips to differentiate thermal damage to proteins from lipid co-oxidation during processing and storage. In a previous study, gel electrophoresis revealed modification of protein surfaces that affected dye binding, as well as formation of sizeable protein aggregates too large to enter normal gels involving disulfide, free radical, and other crosslinks. As an alternative to polyacrylamide gels, capillary electrophoresis can separate peptides without molecular weight limits, by modes that may be more sensitive to side chain modifications, and requires only a few nanoliters of sample. Thus, this study investigated the use of capillary electrophoresis for tracking fragmentation and crosslinking in co-oxidized proteins. Results corroborated observations that fried tortilla chip samples had greater changes than baked tortilla chip samples and higher incubation temperature resulted in more protein damage, most notably in fried reducing fractions. In addition, surface modifications altered protein charge, which interfered with migration in capillary electrophoresis. Peptide detection was limited to zeins of about 50 kDa because the sample filtration step intended to prevent capillary blockage also removed higher molecular weight fractions, including glutelins. However, fragmentation products not distinguishable in gel electrophoresis were detected. Overall, results of this study suggest that capillary electrophoresis has intriguing possibilities for supplementing SDS-PAGE and other protein analyses, particularly in verifying the presence of surface modifications. However, significant hurdles—such as reasons for lack of high molecular weight peptide loading and migration—remain to be overcome before capillary electrophoresis can become a primary method for analysis of modified proteins.M.S.Includes bibliographical referencesby Lisa Hayley Schult
Hayley's biography of Dante
William Hayley’s literary relationship with Dante had a central role in the rediscovery of the Italian poet at the turn of the nineteenth century in England. His knowledge of Dante likely dates back to his student years at Trinity Hall in the 1760s, when he learned “to read, write, and speak Italian with fluency” from his master Agostino Isola, “an elderly, ingenious and distressed Italian” who taught in Cambridge. Hayley invoked Dante in The Triumphs of Temper (1781) and An Essay on Epic Poetry (1782) and was one of the earliest to attempt rendering the Commedia from the original terza rima, offering the most extended English version available in print at the time. The translation was first published in his notes to An Essay on Epic Poetry and encompassed the first three cantos of Inferno. Contemporary writers’ views on his Dante translation, particularly those expressed by Anna Seward and Horace Walpole, are significant. Seward had little admiration for “the fire and smoke poet” and Walpole was notorious for his hostility to Dante. However, they greatly admired Hayley’s version, even more so than Boyd’s. In a letter to Helen Williams, Seward confesses that “after reading and comparing it with Mr. Hayley’s sublime English version of the three first cantos, we cannot place great confidence in Boyd’s justice to his author” (25 August 1785). Boyd himself praised Hayley’s translation and highlighted that in his edition “many biographical particulars of Dante, are taken from Mr. Hayley’s Notes to his Essay on Epic Poetry.” But Hayley’s An Essay on Epic Poetry, apart from his acclaimed translation of the Commedia, includes other noteworthy parts such as his translations of sonnets by Dante, Petrarch, and Camõens and a series of European poets’ biographies, including those of Dante, Boccaccio, and Tasso. In his sketch of Dante’s life, Hayley emphasizes “the lighter graces of sprightly composition,” going beyond the common perception of Dante as a poet “inclined to melancholy.” Hayley’s notes raise questions about the readership of Italian poetry at the time, particularly in what way poets such as Dante were introduced to the English reader, and how the inclusion of Dante’s biography in An Essay might have contributed to the reception of his verse-in-translation. This chapter revolves around the exploration of these concerns in order to contextualize Hayley as a prominent figure who, besides his important connections to Blake and Romney, crucially contributed to literary and artistic negotiations across borders.</p

Private rhino conservation : diverse strategies adopted in response to the poaching crisis
CITATION: Clements, H. S., et al. 2020. Private rhino conservation : diverse strategies adopted in response to the poaching crisis. Conservation Letters, 2020:e12741, doi:10.1111/conl.12741.The original publication is available at https://conbio.onlinelibrary.wiley.comPublication of this article was funded by the Stellenbosch University Open Access Fund.Private landowners in South Africa conserve roughly 40% of white rhinos globally. Given concerns that escalating poaching has caused private‐rhino owners to disinvest, we used a national survey to assess 171 private‐rhino owners’ responses to the crisis. Twenty‐eight percent of rhino owners are disinvesting in rhino, 57% are pursuing business‐as‐usual (largely ecotourism), and 15% are investing in more rhinos. It is currently unclear whether this diversity in private‐rhino owners’ responses to the crisis is increasing the resilience of the rhino population to poaching. Some rhino investors show signs of financial stress. Most owners support rhino‐horn trade to fund conservation, yet international trade remains banned. By contrast, a recent national policy amendment allows rhinos to be managed as livestock, risking a shift from rhino‐for‐conservation to rhino‐for‐production on private land. Our findings highlight an urgent need to ensure policies keep pace with dynamic socioeconomic environments that influence the sustainability of wildlife use.https://conbio.onlinelibrary.wiley.com/doi/abs/10.1111/conl.12741Publisher's versio
Understanding the socio-economic contributions of different wildlife ranching business models in South Africa
Amidst the biodiversity loss crisis, the expansion of wildlife ranching has been associated with a numerous conservation benefits and linked to job creation and substantial economic contributions. However, an understanding of the socio-economic contributions of wildlife ranching that account for the heterogeneity and diverse business strategies within the wildlife economy remains limited. The aim of this research was to determine some of the socio-economic contributions of different wildlife-based business models, as defined by their main revenue-generating activities, within the wildlife ranching industry in South Africa, as well as the financial sustainability of these business models and their contributions. In total, 268 owners and managers of privately-owned wildlife ranches and agricultural farms (for comparative purposes) in the Eastern Cape and Limpopo provinces of South Africa were surveyed. Through these surveys, I collected data on the revenue-generating activities they rely on, differences in their financial metrics, the number of jobs they provided and the salaries and non-salary benefits their employees received. This data was based on a non pandemic year (2019/2020) and a post-Covid-19 pandemic year (2021/2022) to assess the sustainability of ranches in response to a large-scale threat. Through a hierarchical clustering analysis of revenue-generating activities, six business models within the wildlife ranching sector were delineated according to their primary focus: ecotourism, trophy hunting, mixed hunting (i.e., biltong and trophy), mixed wildlife-agriculture, wildlife breeding and trophy hunting-game meat business models. On average, trophy hunting and ecotourism focused business models were found to make greater economic contributions, through high upfront capital investment and operating expenditure, than the mixed wildlife-agriculture and mixed hunting focused models. Ecotourism focused ranches employed more people than all business models except trophy hunting. They also provided higher quality jobs (defined as jobs that increase job security, workplace equality, and job satisfaction through higher compensation) by employing the highest proportion of women (41% on average) and the highest proportion of skilled employees (45% on average) across business models, including when compared with conventional agriculture. Trophy hunting focused ranches also employed more people per hectare than other models (although on average, over a quarter of these jobs are seasonal). They also offer the greatest variety of non-salary benefit types to employees (particularly in the form of housing and food), along with mixed hunting ranches. Trophy hunting ranches are considerably more profitable than ecotourism and wildlife breeding ranches, though there was high variability within the ecotourism model, likely as a result of some being focused on high-end ecotourism, and others on low-end ecotourism. After Covid-19, all business models experienced lower profitability and some enterprises across all business models retrenched employees. On average, the mixed-activity models did not retrench employees post-pandemic. Those that fared better during Covid-19 had more diversified profiles of revenue-generating activities (i.e., the mixed activity models), suggesting that enabling this diversity of approaches is important for the sustainability of wildlife ranching. The evidence presented here advances our understanding of the heterogeneous impacts and responses of wildlife ranches and suggests that differences in the socio-economic contributions of these ranches should be considered across business models as several distinctions exist between these models. A more nuanced approach to understanding the socio-economic contributions of wildlife ranching will benefit the policy discourse surrounding the industry by providing information relevant to specific business models', which may lead to more effective policy implementation and improve the industry's sustainability and growth
Performancemania
Monograph; Hayley Newman (introduction by Aaron Williamson)
Published: Matt’s Gallery, London
Pages 96, Binding softback, Illustration 58 colour, 17 b&w plates,
Dimensions 255mm x 210mm, ISBN 0 907623379

This monograph presents selected performance works made between 1994 and 2001. Actual and fictional performance works are published alongside each other. The book includes Research Output 1 - Connotations Performance Images 1994-1998 (1998).
In his introduction, Aaron Williamson writes that by titling the book Performancemania the author reveals herself as; ‘a long standing enthusiast, or fan, of what she considers to be a genuinely revolutionary moment in art, namely European performance art of the 60s and 70s’. This theme of fandom continues throughout the publication, which is reflexive, visibly modelling itself on the traditional artist’s monograph.
The latter half of the book contains an edited version of a self-interview, extracted from my unpublished doctoral thesis; Locating Performance: Textual Identity and the Performative (University of Leeds, 2001). The self-interview identifies itself as a performance and points to ‘the interview’ as a structure with both a temporal and physical location beyond the page.
The book presents 24 actual performance works alongside 21 fictional ones. Works are presented as images with accompanying texts. Fictional works are embedded in the book, distinguished by the colour of the page and an inverse positioning of image and text.
I am currently represented by Matt’s Gallery. However, this book was published before representation was agreed.

How I Made an 37
“How I Made an 37”
Author: Hayley Lind, B.S. Fashion Industry Management, Philadelphia University, M.A. CUNY Graduate School of Journalism
Abstract:
Fashion counterfeiting takes away more than 750 million jobs and more than 880 jacket by Japanese brand, Sacai, and replicated it by repurposing a denim jacket and replacing the sleeves with polyester fabric. I then went shopping at Bergdorf Goodman to see if I could get service. The goal was to see if craft could replace couture.
