This collection navigates the process of grief after the speaker’s loss of both parents. The speaker struggles to connect with both the dead and the living through her physical intimacy and relationship with a troubled lover. These poems explore and exhume the speaker’s buried memories, moving from moments of wry humor to meaningful and sometimes painful discovery. Ultimately, these poems attempt to reach beyond the self, to transform loss and loneliness from a human condition into a musical tool of art for human connection.

The period of the 18th and 19th centuries was one of great change in the Highlands and Islands of Scotland. Improvement, the Jacobite Rebellions, and the Clearances transformed its communities and landscapes. These events have rightly been a focus of research. However, archaeological approaches have often sought simply to illustrate these processes, rather than create new narratives about life in the past. The resulting picture of the period can over-emphasise economic change whilst failing to reflect the richness and variety of everyday life. This thesis aims to suggest a new approach to the place and period, one which addresses matters often ignored in previous work. Whilst it has an archaeological sensibility, it draws on ideas from outside archaeology, such as landscape theory and on Gaelic oral tradition, an underused resource, to create a novel and broad-based approach to the period. An important part of the method is a synchronic approach that seeks to reconstruct the experience of the landscape at very particular times, engaging fully with the everyday experience of landscape rather than grand historical narratives. Two Hebridean case studies are utilised: Hiort (St Kilda) and Loch Aoineart, South Uist. Thematic discussions drawn from these landscapes are intended as critical assessments of the efficacy of the approach, as well as new narratives about life in the past in themselves. The thesis concludes by comparing the two case studies, reflecting on the merits of the approach, discussing recurrent themes in the work, and considering its wider context and implications. It is concluded that taking a novel approach to the case study landscapes can create narratives that often contrast or expand upon those produced by previous scholars, allow for a more detailed consideration of everyday life in the period, and open up new areas for archaeological enquiry. The extensive and critical use of evidence from Gaelic oral tradition is highlighted as crucial in understanding life and society in the period. The thesis questions the utility of grand historical narratives as a framework for archaeological study of post-medieval Gaeldom and suggests that our understanding of the past is best served by approaching the evidence in ways which allows for many different voices and stories from the past to emerge.

This study had three purposes. First, it aimed to re-conceptualize organization-public relationships (OPRs) in public relations and crisis communication. This OPR re-conceptualization helps find out when the OPR buffering effect or the OPR love-becomes-hate effect happens. Second, it aimed to examine how consumer emotions are influenced by OPRs and influence consumer behavioral intentions. Third, it aimed to address the current problematic operationalization of the concept of consumer. Three pilot studies and one main study were conducted. Apple and Whole Foods were the two brands examined. One crisis that undermined the self-defining attributes shared between the brand and its consumers and another crisis that did not were examined for each brand. Almost 500 Apple consumers and 400 Whole Foods consumers provided usable questionnaires. This study had several major findings. First, non-identifying relationship and identifying relationship were different constructs. Moreover, trust, satisfaction, and commitment were not conceptually separate dimensions of OPRs. Second, the non-identifying relationships offered buffering effects by increasing positive attitudes and tempering anger and disappointment. The identifying relationships primarily offered the love-becomes-hate effects by increasing anger and disappointment. Third, if the crisis was relevant to consumers’ daily lives, brand response strategies were less effective at mitigating consumer negative reactions. Moreover, apology-compensation-reminder strategy was more effective compared to no-comment strategy. However, the apology-compensation-reminder strategy was no more effective than other strategies as long as brands compensate to the victims. Identifying relationships increased the effectiveness of response strategies. If the crisis did not undermine the self-defining attributes shared between consumers and brands, the response strategies worked even better. This study contributes to crisis communication research in multiple ways. First, it advances the OPR conceptualization by demonstrating that non-identifying relationship and identifying relationship are different concepts. More importantly, it advances the theory building of OPRs’ influences on crises by finding out when the buffering effect and the love-becomes-hate effect happen. Second, it adds to emotion research by demonstrating that strong OPRs can lead to negative emotions and positive emotions can have negative behavioral consequences on organizations. Third, the precise operationalization of the concept of consumer gives more insights about consumer reactions to crises.

Being married may raise worker productivity and increase the probability of remaining in a job and, as consequence, obtaining a wage premium -- Yet, this effect may be different for males and females -- In developing countries, such as Colombia, the premium may be larger than in developed countries due to the differing social norms and labor market structures -- Using cross-sectional data from Colombian Household Surveys, this paper examines the marriage wage premium and its evolution in Colombia both at the aggregate level and by gender -- We find a marriage wage premium for both male and female populations; this wage premium is explained by the greater human capital endowment in married people and to employer favoritism due to the “social norms” which consider being married an appropriate behavior and reward it

There has been considerable interest in developing shape-changing soft materials for potential applications in drug delivery, microfluidics and biosensing. These shape- changing materials are inspired by the morphological changes exhibited by plants in nature, such as the Venus flytrap. One specific class of shape-change is that from a flat sheet to a folded structure (e.g., a tube). Such “self-folding” materials are usually composed of polymer hydrogels, and these typically fold in response to external stimuli such as pH and temperature. In order to develop these hydrogels for the previously described applications, it is necessary to expand the range of triggers. The focus of this dissertation is the advancement of shape-changing polymer hydrogels that are sensitive to uncommon cues such as specific biomolecules (enzymes), the substrates for such enzymes, or specific multivalent cations. First, we describe a hybrid gel that responds to the presence of low concentrations of a class of enzymes known as matrix metalloproteinases (MMPs). The hybrid gel was created by utilizing photolithographic techniques to combine two or more gels with distinct chemical composition into the same material. Certain portions of the hybrid gel are composed of a biopolymer derivative with crosslinkable groups. The hybrid gel is flat in water; however, in the presence of MMPs, the regions containing the biopolymer are degraded and the flat sheet folds to form a 3D structure. We demonstrate that hydrogels with different patterns can transform into different 3D structures such as tubes, helices and pancakes. Furthermore, this shape change can be made to occur at physiological concentrations of enzymes. Next, we report a gel with two layers that undergoes a shape change in the presence of glucose. The enzyme glucose oxidase (GOx) is immobilized in one of the layers. GOx catalyzes the conversion of glucose to gluconic acid. The production of gluconic acid decreases the local pH. The decrease in local pH causes one of the layers to swell. As a result, the flat sheet folds to form a tube. The tube unfolds to form a flat sheet when it is transferred to a solution with no glucose present. Therefore, this biomolecule- triggered shape transformation is reversible, meaning the glucose sensing gel is reusable. Furthermore, this shape change only occurs in the presence of glucose and it does not occur in the presence of other small sugars such as fructose. In our final study, we report the shape change of a gel with two layers in the presence of multivalent ions such as Ca2+ and Sr2+. The gel consists of a passive layer and an active layer. The passive layer is composed of dimethylyacrylamide (DMAA), which does not interact with multivalent ions. The active layer consists of DMAA and the biopolymer alginate. In the presence of Ca2+ ions, the alginate chains crosslink and the active layer shrinks. As a result, the gel converts from a flat sheet to a folded tube. What is particularly unusual is the direction of folding. In most cases, when flat rectangular gels fold, they do so about their short-side. However, our gels typically fold about their long-side. We hypothesize that non-homogeneous swelling determines the folding axis.

Louise Erdrich (s. 1954) on yksi tunnetuimmista yhdysvaltalaisista Pohjois-Amerikan alkuperäiskansoihin kuuluvista kirjailijoista. Hänen juuriltaan saksalais-amerikkalainen sekä kuuluu chippewa-heimoon. Erdrichin esikoisromaani Love Medicine (1984) sijoittuu kuvitteelliseen chippewa-heimon reservaattiin Pohjois-Dakotassa. June Morriseyn kuoleman jälkeen hänen sukulaisensa kokoontuvat Kashpawien taloon muistelemaan häntä. Junen läheisten elämä avautuu lukijalle eri kertojien äänellä 1930-luvulta 1980-luvulle. Keskityn siihen, kuinka romaanin henkilöt selviytyvät valkoisen valtakulttuurin ja alisteisessa asemassa olevan chippewa-kulttuurin välitilassa. Tarkastelen erityisesti kulttuurisen muistin roolia henkilöiden selviytymisstrategioissa. Kulttuurinen muisti on sosiaalisesti muodostettua yhteistä tietoa menneisyyden tapahtumista ja ryhmää koossa pitävästä merkitysjärjestelmästä. Traditio ja yhteisöllisyys merkitsevät heimoyhteisölle voimaantumisen mahdollisuutta, toivoa kulttuurisen tyhjiön täyttämisestä ja katkenneiden sosiaalisten siteiden korjaamisesta. Kulttuurinen muisti tarjoaa romaanin henkilöille mahdollisuuden muodostaa yhteyden heimon kulttuuriperintöön. Erdrich hyödyntää romaanissaan monenlaisia viittauksia sekä chippewa-mytologiaan että valkoiseen kulttuuriin. Monet chippewa-perinteen ainekset, kuten trickster-hahmot, lemmenlääke ja laaja perhekäsitys, toimivat välineinä, joiden avulla romaanin henkilöt rakentavat identiteettiään ja pyrkivät löytämään paikkansa yhteisössä. Tarkastelen myös sitä, miten osa henkilöistä pyrkii assimiloitumaan ja saavuttamaan toimijuutta valkoisen valtakulttuurin keinoin. Yhteisöllisyyden ja kulttuurin eteenpäin siirtämisen voima mahdollistaa sen, että nuori sukupolvi löytää paikkansa ja asettuu osaksi heimon jatkumoa. Vaikka kolonisaatiota ja sen aiheuttamia tuhoja ei voi kumota, chippewa-traditio ei sammu, vaan Erdrichin romaani osoittaa, että selviytyminen on mahdollista.

The novel Jane Eyre, written by Charlotte Brontë, is very appreciated and famous. It has been adapted several times into different media, such as films, musicals and theatres. In this essay I will compare the novel with Cary Joji Fukunaga’s film adaption from 2011. I will compare the characters Jane Eyre and Mr. Rochester and examine how they are portrayed, and I will also discuss the difference between Mr. Brocklehurst in the novel and in the film. I argue that the characters and some of the situations are adjusted to fit a modern audience. I also argue that the film is a romanticized, de-politicized version of the novel. Many of Jane’s reflections upon life, love, class, gender and so on are less developed in the film and the film is more of a love story than a story about a young woman’s life in the Victorian era.

Using the concept of time travel as a contextual and narrative tool, the author explores themes of love, loss and growth after trauma. Reflections relate primarily to the experience of conducting the qualitative research method of autoethnography. Opening with consideration of existing work (Yoga and Loss: An Autoethnographical Exploration of Grief, Mind, and Body), discussion moves on to academic thought on mental time travel, and personal transformation, culminating in the construction of a new memory combining past, present, and future.

One of the main features of nineteenth-century fiction is the quasi-total disappearance of the epistolary novel that had had its heydays in the previous century. For this reason, some scholars have declared the “death” of the letter in literature after the transitional romantic period. However, Victorian novels overflow with letters that are embedded, quoted in part or described and commented on by narrators or characters. Even when its content is not revealed to the reader, the letter becomes a signifier loaded with meanings, also and particularly so, when it is burnt, torn, hidden, found or buried. The Postal Reform of 1839-40 caused the number of letters sent every year in Britain to grow from 75 to 410 million in only 14 years, and the mediatic campaign that supported it drew the attention of the population to the material aspects concerning this means of communication. Newspapers became more affordable too and they promoted a taste for sensationalism that often involved the “spectacularization” of private correspondence. Starting from an excursus on the history of the letter aimed at identifying the key aspects of the genre, this work deals with some real love correspondences from people belonging to different classes in the period from 1840 to the 1870s, to then analyse their fictional and pictorial counterparts. The general picture that emerges from this analysis is that of a Victorian society where letters were able to break down the boundaries between high and low forms of cultural expressions and where, more than ever, letters were present in people’s everyday lives as well as in the art and literature they enjoyed.
