A comprehensive analysis of contrast formation mechanisms in scanning tunneling microscopy (STM) experiments on a metal oxide surface is presented with the oxygen-induced (2√2×√2)R45 missing row reconstruction of the Cu(100) surface as a model system. Density functional theory and electronic transport calculations were combined to simulate the STM imaging behavior of pure and oxygen-contaminated metal tips with structurally and chemically different apexes while systematically varying bias voltage and tip-sample distance. The resulting multiparameter database of computed images was used to conduct an extensive comparison with experimental data. Excellent agreement was attained for a large number of cases, suggesting that the assumed model tips reproduce most of the commonly encountered contrast-determining effects. Specifically, we find that depending on the bias voltage polarity, copper-terminated tips allow selective imaging of two structurally distinct surface Cu sites, while oxygen-terminated tips show complex contrasts with pronounced asymmetry and tip-sample distance dependence. Considering the structural and chemical stability of the tips reveals that the copper-terminated apexes tend to react with surface oxygen at small tip-sample distances. In contrast, oxygen-terminated tips are considerably more stable, allowing exclusive surface oxygen imaging at small tip-sample distances. Our results provide a conclusive understanding of fundamental STM imaging mechanisms, thereby providing guidelines for experimentalists to achieve chemically selective imaging by properly selecting imaging parameters. © 2013 American Chemical Society.

Investigators are continually faced with the task of detecting deception. Assessment Criteria Indicative of Deception (ACID) is a system of interviewing and credibility assessment that maximizes verbal cues to detect deception, and teaches content analysis that highlights attempts to withhold, distort, or manipulate information. The ACID technique has been successful in discriminating honest from deceptive statements when credibility determinations are made either by statistical methods or trained raters. Unfortunately, the training has required several hours and application has required the time-consuming process of transcription. The current study demonstrates the utility of ACID following a brief training, and compares the credibility ratings made from analysis of transcripts to the credibility ratings made from the analysis of audio recordings. Twenty-nine university undergraduate and graduate students read or listened to a series of eight transcripts. Raters were provided with accounts before training and 4 accounts after training. Prior to training, raters performed at 55% accuracy. Following training, raters performed at 71% accuracy. Additionally, there was an untrained control group that performed at 53% accuracy. Of note, the post-training performance was identical for accounts presented in written and audio formats. In sum, the ACID technique was reliable, valid, easy to train, and showed that accurate decisions can be made from simple audio recordings. Copyright 2013 American Journal of Forensic Psychology,.

Home health care is an important aspect of community health and a growing area of healthcare services. Clinical Case Studies in Home Health Care uses a case-based approach to provide home healthcare professionals, educators, and students with a useful tool for thoughtful, holistic care. The book begins with a thorough and accessible introduction to the principles of home health care, including a discussion of supporting theoretical frameworks and information on managing complexities, transitioning patients to home care, and preparation for the home visit. Subsequent sections are comprised entirely of case studies organized by body system. Though cases are diverse in content, each is presented in a consistent manner, incorporating relevant data about the patient and caregivers and the approach to patient care and promoting a logical approach to patient presentation. Cases also include helpful tips about reimbursement practices, cultural competence, community resources, and rehabilitation needs. © 2011 by John Wiley & Sons, Inc.

'Rauisuchia' comprises Triassic pseudosuchians that ranged greatly in body size, locomotor styles and feeding ecologies. Our concept of what constitutes a rauisuchian is changing as a result of discoveries over the last 15 years. New evidence has shown that rauisuchians are probably not a natural (monophyletic) group, but instead are a number of smaller clades (e.g. Rauisuchidae, Ctenosauriscidae, Shuvosauridae) that may not be each other's closest relatives within Pseudosuchia. Here, we acknowledge that there are still large gaps in the basic understanding in the alphalevel taxonomy and relationships of these groups, but good progress is being made. As a result of renewed interest in rauisuchians, an expanding number of recent studies have focused on the growth, locomotor habits, and biomechanics of these animals, and we review these studies here. We are clearly in the midst of a renaissance in our understanding of rauisuchian evolution and the continuation of detailed descriptions, the development of explicit phylogenetic hypotheses, and explicit palaeobiological studies are essential in advancing our knowledge of these extinct animals. © The Geological Society of London 2013.

"Pina Palma's Savoring Power, Consuming the Times: The Metaphors of Food in Medieval and Renaissance Italian Literature is an innovative look at the writings of five important Italian authors--Boccaccio's Decameron, Pulci's Morgante, Boiardo's Innamorato, Ariosto's Furioso, and Aretino's Ragionamento. Through the prism of gastronomy, Palma examines these key works in the Western literary canon, bringing into focus how their authors use food and gastronomy as a means to critique the social, political, theological, philosophical, and cultural beliefs that constitute the fabric of the society in which they live." -- Publisher's website.

Friday Night Fighter relives a lost moment in American postwar history, when boxing ruled as one of the nation's most widely televised sports. During the 1950s and 1960s, viewers tuned in weekly, sometimes even daily, to watch widely-recognized fighters engage in primordial battle, with the Gillette Cavalcade of Sports Friday Night Fights being the most popular fight show. Troy Rondinone follows the dual narratives of the Friday Night Fights show and the individual story of Gaspar "Indio" Ortega, a boxer who appeared on primetime network television more than almost any other boxer in history. From humble beginnings growing up poor in Tijuana, Mexico, Ortega personified the phenomenon of postwar boxing at its greatest, appearing before audiences of millions to battle the biggest names of the time, such as Carmen Basilio, Tony DeMarco, Chico Vejar, Benny "Kid" Paret, Emile Griffith, Kid Gavilan, Florentino Fernández, and Luis Manuel Rodriguez.--(Source of description unspecified.)

Among language testing researchers, the notion of fairness has accumulated a number of complex, technical definitions over the years. However, since the word has such a widespread, everyday usage, consulting a dictionary can be a good starting-point for discussion. For example, YourDictionary.com (2011) states that to be fair is to be “just and honest,” “impartial,” and “unprejudiced,” specifically, “free from discrimination based on race, religion, sex, etc.“Merriam-Webster (Mish et al., 2003) states similarly that fairness is “marked by impartiality or honesty” and is “free from self-interest, prejudice, or favoritism.” As this volume deals with second/foreign/other language testing, it would seem appropriate (or perhaps one should say, fair) to include a dictionary definition crafted for L2 learners, as is this one from Cambridge (Walter et al., 2006): “Treating someone in a way that is right or reasonable, or treating a group of people equally and not allowing personal opinions to influence your judgment.”. © 2012 Selection and editorial matter, Glenn Fulcher and Fred Davidson.

Physical mistreatment has been estimated to affect 2 million older persons each year and dramatically affects health outcomes. While researchers have attempted to examine risk factors for specific forms of abuse, many have been able to focus on only victim or perpetrator characteristics, or a limited number of psychosocial variables at any one time. Additionally, data on risk factors for subgroups such as persons with Alzheimer's disease who may have heightened and/or unique risk profiles has also been limited. This paper examines risk for physical violence in caregiver/patient dyads who participated in the Aggression and Violence in Community-Based Alzheimer's Families Grant. Data were collected via in-person interview and mailed survey and included demographics as well as measures of violence, physical and emotional health, and health behaviors. Logistic regression analysis indicated that caregivers providing care to elders with high levels of functional impairment or dementia symptoms, or who had alcohol problems, were more likely to use violence as a conflict resolution strategy, as were caregivers who were providing care to elders who used violence against them. By contrast, caregivers with high self-esteem were less likely to use violence as a conflict resolution strategy. Significant interaction effects were also noted. © 2013 Carla VandeWeerd et al.

As the fastest growing population sector worldwide, older adults are seen in almost every care setting in which clinicians practice. Developed as a resource for advanced practice nurses in any setting, Case Studies in Gerontological Nursing for the Advanced Practice Nurse presents readers with a range of both typical and atypical cases from real clinical scenarios. The book is organized into six units covering cases related to ageism, common health challenges, health promotion, environments of care, cognitive and psychological issues, and issues relating to aging and independence. Each case follows a similar format including the patient's presentation, critical thinking questions, and a thorough discussion of the case resolution through which students and clinicians can enhance their clinical reasoning skills. Designed to promote geriatric clinical education through self-assessment or classroom use, Case Studies in Gerontological Nursing for the Advanced Practice Nurse is a key resource for all those dedicated to improving care for older adults. © 2012 by John Wiley & Sons, Inc.

A successful Software maintenance process depends on three factors: the maintenance goals, the technical properties of the system and the people performing the software maintenance. Most of the current work to investigate software maintenance only considers the first two factors, ignoring the third factor, which limits the scope and accuracy of these approaches. In this paper, we use change theory to introduce a deeper understanding of the software maintenance process. We utilize three change theories: Lewin's, Prochaska and DiClemente's, and Lippit's theories to introduce three different software maintenance models. These models consider the three success factors and incorporate contextual information to help maintainers better understand the software maintenance task to bring about an effective change.

Introduction: Like medicine, public health practitioners seek to understand causes of mortality, practices of humans and issues that can change population conditions, in order to preserve and care for life. The murder pandemic has been such in Jamaica that the World Bank sponsored a qualitative study on crime in urban areas in Jamaica in the late 1990s to provide a platform to guide policy intervention and programmes. As a result this study will fill the gap in the literature by providing the evidence to support that divorce and marriage are public health concerns from the perspective of murders. Objective: To evaluate the role of divorce and marital relationships on murders. Materials and methods: The data for this study are taken from various Jamaica Government Publications. The period for this work is from 1950 through 2013. Data were recorded, stored and retrieved using the Statistical Packages for the Social Sciences (SPSS) for Windows, Version 21.0. The level of significance that is used to determine statistical significance is less than 5% (0.05). Ordinary least square (OLS) regression analyses and curve estimations were used to determine models and best fitted models. Results: On average, annually, 523 Jamaicans are murdered (± 484), with there being 9,531 marriages (±22,747) and 904 divorces (±468). Logged marriage rate and divorce rate are factors of murder rate, with both independent factors accounting for 82.2% of the variability in the murder rate. Both factors are positively correlated with the murder rate, with the divorce rate accounting for most of the variance in the murder rate (R2 = 79.2%). Conclusion: Death can be extremely devasting to families, however, murder among married couples can severely disrupt the lives of both families along with any children from such relationship. © 2014, Chevron Publishing Corporation.
