Interactions and the Theta Term in One-Dimensional Gapped Systems

We study how the \theta -term is affected by interactions in certain one-dimensional gapped systems that preserve charge-conjugation, parity, and time-reversal invariance. We exploit the relation between the chiral anomaly of a fermionic system and the classical shift symmetry of its bosonized dual. The vacuum expectation value of the dual boson is identified with the value of the \theta -term for the corresponding fermionic system. Two (related) examples illustrate the identification. We first consider the massive Luttinger liquid and find the \theta -term to be insensitive to the strength of the interaction. Next, we study the continuum limit of the Heisenberg XXZ spin-1/2 chain, perturbed by a second nearest-neighbor spin interaction. For a certain range of the XXZ anisotropy, we find that we can tune between two distinct sets of topological phases by varying the second nearest-neighbor coupling. In the first, we find the standard vacua at \theta = 0, \pi, while the second contains vacua that spontaneously break charge-conjugation and parity with fractional \theta / \pi = 1/ 2, 3/2. We also study quantized pumping in both examples following recent work.Comment: 17 pages, harvmac; v.2 typo corrected and slight re-wording

On the Cognition of States of Affairs

The theory of speech acts put forward by Adolf Reinach in his "The A Priori Foundations of the Civil Law" of 1913 rests on a systematic account of the ontological structures associated with various different sorts of language use. One of the most original features of Reinach's account lies in hIs demonstration of how the ontological structure of, say, an action of promising or of commanding, may be modified in different ways, yielding different sorts of non-standard instances of the corresponding speech act varieties. The present paper is an attempt to apply this idea of standard and modified instances of ontological structures to the realm of judgement and cognition, and thereby to develop a Reinachian theory of how intentionality is mediated through language in acts of thinking and speaking

The Original Progressive Farmer: The Agricultural Legacy of Thomas Spalding of Sapelo

During the first half of the nineteenth century, a thriving plantation emerged on Sapelo Island, Georgia. The plantation’s owner was Thomas Spalding (1774-1851), who was one of Georgia’s foremost planters, and yet his substantial contributions to Georgia’s agricultural development have gone unnoticed by most historians. Spalding built a prosperous enterprise around staple crops such as Sea Island cotton; however, he was better known for his experiments with novel crops such as sugar cane, as well as his innovations in the areas of crop rotation and diversification and the successful implementation of tabby as a viable construction material on the Georgia coast. This paper analyzes these areas of Spalding’s career with particular attention given to his extensive writings on the subjects in the leading agricultural journals of the period. Spalding’s accomplishments are many, and this study seeks to shed new light on his most noteworthy agricultural endeavors and to demonstrate that his life and career deserve further investigation by historians

Tax professionals at work in Silicon Valley

Article in Press© 2015 Elsevier Ltd. This paper analyses a previously unexamined but nonetheless important facet of modern society - the nature and impact of the relationship between in-house tax professionals in large multinational organizations, and the external business, tax and regulatory environments within which they operate. Drawing on face-to-face interviews conducted with senior tax executives in US multinational enterprises (MNEs), we uncover the social reality of the world in which MNEs' tax executives operate, and find that these tax professionals are a powerful, elite group of knowledge experts who can significantly shape tax law and practices. We analyze the activities of these experts who, although working largely in the shadows of their organizations, are very much engaged in constructing and shaping the wider institutional environment. From a theoretical perspective that brings together institutional work and the endogeneity of law, we find these elite professionals engaging in subtle and diffuse exercise of power at a micro level within their organizations, a meso level between organizations within the field and at a macro level within the wider external environment. This has important implications for our broader understanding of the tax and regulatory environments which corporate actors inhabit

An Examination of Australians of Hellenic Descent in the State Parliament of Victoria

Continuing a series of analyses of the role of elected State and Federal representatives of Hellenic descent in Australia, this paper will focus on the Victorian State Parliament, but with reference also to current and former Victorian Federal parliamentarians

Citizenship education in New Zealand: policy and practice

The desire to mould citizens through curricula and educational initiatives is reflected in government policy around the world. Schools can be thought of as an aggregation of the values, aspirations and ideals held by society and sites where a range of strategies are employed to attempt to shape young citizens in certain ways (Staeheli, 2011). New Zealand is no exception. From the first Education Act in 1877 through to the latest New Zealand curriculum (Ministry of Education, 2007), successive governments have attempted to engender the dispositions, skills and understandings perceived as constituting responsible, ‘good’ citizens through a variety of citizenship education initiatives.&nbsp

Testosterone replacement therapy for older men

Despite intensive research on testosterone therapy for older men, important questions remain unanswered. The evidence clearly indicates that many older men display a partial androgen deficiency. In older men, low circulating testosterone is correlated with low muscle strength, with high adiposity, with insulin resistance and with poor cognitive performance. Testosterone replacement in older men has produced benefits, but not consistently so. The inconsistency may arise from differences in the dose and duration of testosterone treatment, as well as selection of the target population. Generally, studies reporting anabolic responses to testosterone have employed higher doses of testosterone for longer treatment periods and have targeted older men whose baseline circulating bioavailable testosterone levels were low. Most studies of testosterone replacement have reported anabolic that are modest compared to what can be achieved with resistance exercise training. However, several strategies currently under evaluation have the potential to produce greater anabolic effects and to do so in a safe manner. At this time, testosterone therapy can not be recommended for the general population of older men. Older men who are hypogonadal are at greater risk for the catabolic effects associated with a number of acute and chronic medical conditions. Future research is likely to reveal benefits of testosterone therapy for some of these special populations. Testosterone therapy produces a number of adverse effects, including worsening of sleep apnea, gynecomastia, polycythemia and elevation of PSA. Efficacy and adverse effects should be assessed frequently throughout the course of therapy

A Quiet Celebration of Whitman’s 200th Birthday: A Collaborative Opportunity to Discover, Grow, and Share a Collection

Over the past several years, special collections libraries and archives have been more proactive in engaging in educational outreach and promoting forward-facing programs. Additionally, subject and special collections librarians have sought ways to expand their collaboration to maximize their reach and impact. The occasion of the 200th anniversary of Walt Whitman’s birth was the perfect opportunity for two librarians at Binghamton University to collaborate, promote a jewel from the Libraries’ holdings, build a stronger collection, and interact with local audiences through an exhibit and events

Dentistry

The specialty of Dental Surgery has progressed from the "blood and acrylic" of the early seventies. Dentistry has undergone a quantum leap over the past twenty-five years, with improvements in both technique and technology, bringing us the sophisticated procedures used in today's practice.peer-reviewe
