The Effect of EDTA in Attachment Gain and Root Coverage

Root surface biomodification using low pH agents such as citric acid and tetracycline has been proposed to enhance root coverage following connective tissue grafting. The authors hypothesized that root conditioning with neutral pH edetic acid would improve vertical recession depth, root surface coverage, pocket depth, and clinical attachment levels. Twenty teeth in 10 patients with Miller class I and II recession were treated with connective tissue grafting. The experimental sites received 24% edetic acid in sterile distilled water applied to the root surface for 2 minutes before grafting. Controls were pretreated with only sterile distilled water. Measurements were evaluated before surgery and 6 months after surgery. Analysis of variance was used to determine differences between experimental and control groups. We found significant postoperative improvements in vertical recession depth, root surface coverage, and clinical attachment levels in test and control groups, compared to postoperative data. Pocket depth differences were not significant (P\u3c.01)

Early Relationships, Pathologies of Attachment, and the Capacity to Love

Psychologists often characterize the infant’s attachment to her primary caregiver as love. Philosophical accounts of love, however, tend to speak against this possibility. Love is typically thought to require sophisticated cognitive capacities that infants do not possess. Nevertheless, there are important similarities between the infant-primary caregiver bond and mature love, and the former is commonly thought to play an important role in one’s capacity for the latter. In this work, I examine the relationship between the infant-primary caregiver bond and love. I argue that while these very early attachments do not represent genuine love, a fuller understanding of them can inform extant philosophical views of love

Attachments to nature : design and eco-emotion

This paper is concerned with how technology influences people’s emotional attachments to nature. The paper proposes two theoretical works in progress: a model which shows how emotions are constructed through social, technological and ecological experience; and a framework which proposes ways in which technology influences the construction of emotional attachments to nature. The aim of these models and frameworks are to enable designers to reframe their perceptions of ecological issues and recognise the behavioural, cultural and social complexities. The paper also hopes to further the relevance of the design and emotion field to sustainable development. The paper emerges from an investigation into an anthropological approach to ecodesign, and one of the key aims of presenting the paper is to understand its relevance of this enquiry to the design and emotion field

Wild Emptiness: A Zen Approach to Environmental Ethics

When Buddhism took root in China and integrated with the nation’s Taoist intellectual climate, the tradition retained the orthodox central objective of overcoming suffering. While conserving this principal aspiration, the rise of Zen is associated with deviation from the orthodox practice of monasticism and toward the practical embodiment of emptiness while integrated in society, which can be likened to the practice of unwavering compassion. This piece offers a Zen approach to environmental ethics such that it is an attempt to explicate how and why an individual practicing Zen should compassionately engage with the earth. With respect to the Buddhist employment of skillful means, different approaches are offered as tailored ethical frameworks to appeal to individuals at different stages in their path to awakening. Furthermore, the environmental ethic appealed to by the awakened individual is explicated as spontaneous harmonization with the flow of emptiness, that which the Buddhists regard to be the driving force of the phenomenal realm. The awakened individual is considered to non-deliberately take on a lifestyle that provides perpetual intimacy with the rhythms of wild emptines

Developmental Stages of Perception and Language Acquisition in a Perceptually Grounded Robot

The objective of this research is to develop a system for language learning based on a minimum of pre-wired language-specific functionality, that is compatible with observations of perceptual and language capabilities in the human developmental trajectory. In the proposed system, meaning (in terms of descriptions of events and spatial relations) is extracted from video images based on detection of position, motion, physical contact and their parameters. Mapping of sentence form to meaning is performed by learning grammatical constructions that are retrieved from a construction inventory based on the constellation of closed class items uniquely identifying the target sentence structure. The resulting system displays robust acquisition behavior that reproduces certain observations from developmental studies, with very modest “innate” language specificity

IPv6 Network Mobility

Network Authentication, Authorization, and Accounting has been used since before the days of the Internet as we know it today. Authentication asks the question, “Who or what are you?” Authorization asks, “What are you allowed to do?” And fi nally, accounting wants to know, “What did you do?” These fundamental security building blocks are being used in expanded ways today. The fi rst part of this two-part series focused on the overall concepts of AAA, the elements involved in AAA communications, and highlevel approaches to achieving specifi c AAA goals. It was published in IPJ Volume 10, No. 1[0]. This second part of the series discusses the protocols involved, specifi c applications of AAA, and considerations for the future of AAA
