This article describes a revised Conflict Tactics Scales (the CTS2) to measure psychological and physical attacks on a partner in a marital, cohabiting, or dating relationship; and also use of negotiation. The CTS2 has (a) additional items to enhance content validity and reliability; (b) revised wording to increase clarity and specificity; (c) better differentiation between minor and severe levels of each scale; (d) new scales to measure sexual coercion and physical injury; and (e) a new format to simplify administration and reduce response sets. Reliability ranges from .79 to .95. There is preliminary evidence of construct validity.

Relative quantities of DNA in individual nuclei of stem and leaf epidermal cells of Arabidopsis were measured microspectrofluorometrically using epidermal peels. The relative ploidy level in each nucleus was assessed by comparison to root tip mitotic nuclei. A clear pattern of regular endopolyploidy is evident in epidermal cells. Guard cell nuclei contain levels of DNA comparable to dividing root cells, the 2C level (i.e., one unreplicated copy of the nuclear DNA). Leaf trichome nuclei had elevated ploidy levels of 4C, 8C, 16C, 32C, and 64C, and their cytology suggested that the polyploidy represents a form of polyteny. The nuclei of epidermal pavement cells were 2C, 4C, and 8C in stem epidermis, and 2C, 4C, 8C, and 16C in leaf epidermis. Morphometry of epidermal pavement cells revealed a direct proportionality between nuclear DNA level and cell size. A consideration of the development process suggests that the cells of highest ploidy level are developmentally oldest; consequently, the developmental pattern of epidermal tissues can be read from the ploidy pattern of the cells. This observation is relevant to theories of stomate spacing and offers opportunities for genetic analysis of the endopolyploidy/polyteny phenomenon.

Clostridioides difficile infection occurs when the bacterium produces toxin that causes diarrhea and inflammation of the colon. These guidelines indicate the preferred approach to the management of adults with C. difficile infection and represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation process. In instances where the evidence was not appropriate for Grading of Recommendations Assessment, Development, and Evaluation but there was consensus of significant clinical merit, key concept statements were developed using expert consensus. These guidelines are meant to be broadly applicable and should be viewed as the preferred, but not the only, approach to clinical scenarios.

A study by a ITiCSE 2001 working group ("the McCracken Group") established that many students do not know how to program at the conclusion of their introductory courses. A popular explanation for this incapacity is that the students lack the ability to problem-solve. That is, they lack the ability to take a problem description, decompose it into sub-problems and implement them, then assemble the pieces into a complete solution. An alternative explanation is that many students have a fragile grasp of both basic programming principles and the ability to systematically carry out routine programming tasks, such as tracing (or "desk checking") through code. This ITiCSE 2004 working group studied the alternative explanation, by testing students from seven countries, in two ways. First, students were tested on their ability to predict the outcome of executing a short piece of code. Second, students were tested on their ability, when given the desired function of short piece of near-complete code, to select the correct completion of the code from a small set of possibilities. Many students were weak at these tasks, especially the latter task, suggesting that such students have a fragile grasp of skills that are a prerequisite for problem-solving.

Nursing research often requires inquiry into sensitive topics that involve hidden or hard- to reach populations. However, identifying and sampling these populations for research purposes is often fraught with difficulties. Barriers include society's lack of tolerance of diverse groups, social stigma, concern for issues of confidentiality, and fear of exposure because of possible threats to security. Chain referral sampling techniques are proposed to minimize bias while maintaining privacy and confidentiality. Techniques of chain referral sampling are detailed for use in researching sensitive topics and hidden populations. When carefully planned and executed, this sampling design offers transcultural nurse researchers a reasonable method for accessing and studying special populations that are particularly hard-to-reach.

In this study, we build on recent social disorganization research, estimating models of the relationships between disorder, burglary, cohesion, and fear of crime using a sample of neighborhoods from three waves of the British Crime Survey. The results indicate that disorder has an indirect effect on burglary through fear and neighborhood cohesion. Although cohesion reduces disorder, nonrecursive models show that disorder also reduces cohesion. Part of the effect of disorder on cohesion is mediated by fear. Similar results are obtained in nonrecursive burglary models. Together, the results suggest a feedback loop in which decreases in neighborhood cohesion increase crime and disorder, increasing fear, in turn, further decreasing cohesion.

The Politics of Home examines the changing representations of home in twentieth-century English literature. Examining imperial fiction, contemporary literary and cultural theory, and postcolonial narratives on belonging, exile and immigration, Rosemary Marangoly George argues that literary allegiances are always more complicated than expected and yet curiously visible in textual reformulations of home. She reads English women's narration of their success in the empire against Joseph Conrad's accounts of colonial masculine failure, R. K. Narayan alongside Frederic Jameson, contemporary Indian women writers as they recycle the rhetoric of the British Romantic poets, Edward Said next to M. G. Vassanji and Jamaica Kincaid, and Conrad through Naipaul and Ishiguro.

Blending strong narrative history and a fascinating look at the interface of business and technology, Computer: A History of the Information Machine traces the dramatic story of the invention of the computer. Earlier histories of the computer have depicted it as a tool both created by and to be used by scientists to solve their own number-crunching problems - as late as 1949 it was thought by some that the world would never need more than a dozen machines. This book suggests a richer story behind the computer's creation, one that shows how business and government were the first to explore the unlimited potential of the machine as an information processor. Not surprisingly, at the heart of the business story is the name IBM

Two hundred and seventy five randomly selected social workers who were practicing in Massachusetts in 1988 were studied to better understand burnout and job satisfaction. The findings from hierarchical multiple regressions revealed that perceived lack of autonomy and the influence of the funding sources are major contributors to burnout, and perceived autonomy and bureaucratization are major contributors to job satisfaction. The findings challenge the assumption that bureaucracy is the most efficient form of organization and question the ideological and social control functions of organizations. A focus on the effects of the organizational structure as it contributes to burnout and job satisfaction is suggested for policy, practice, and professional decisions.

Abstract The growth of outsourcing has led outsourcing strategies to become an increasingly important component of firm success (Gottfredson et al., 2005). While the purported goal of outsourcing in supply chains is to derive a competitive advantage, it is not clear whether the outsourcing decisions of firms are always strategically aligned with their overall competitive strategy. In this paper we evaluate the degree of congruence (fit or alignment) between a firm's outsourcing drivers and its competitive priorities and assess the impact of congruence on both supply chain performance and business performance, using empirical data collected from manufacturing business units operating in the United States. We find outsourcing congruence across all five competitive priorities to be positively and significantly related to supply chain performance. We also find the level of supply chain performance in a firm to be positively and significantly associated with the firm's business performance.

OBJECTIVES: Previous attempts at meta-analysis and systematic review have not provided clear recommendations for the clinical application of thermal ablation in metastatic colorectal cancer. Many authors believe that the probability of gathering randomised controlled trial (RCT) data is low. Our aim is to provide a consensus document making recommendations on the appropriate application of thermal ablation in patients with colorectal liver metastases. METHODS: This consensus paper was discussed by an expert panel at The Interventional Oncology Sans Frontières 2013. A literature review was presented. Tumour characteristics, ablation technique and different clinical applications were considered and the level of consensus was documented. RESULTS: Specific recommendations are made with regard to metastasis size, number, and location and ablation technique. Mean 31 % 5-year survival post-ablation in selected patients has resulted in acceptance of this therapy for those with technically inoperable but limited liver disease and those with limited liver reserve or co-morbidities that render them inoperable. CONCLUSIONS: In the absence of RCT data, it is our aim that this consensus document will facilitate judicious selection of the patients most likely to benefit from thermal ablation and provide a unified interventional oncological perspective for the use of this technology. KEY POINTS: • Best results require due consideration of tumour size, number, volume and location. • Ablation technology, imaging guidance and intra-procedural imaging assessment must be optimised. • Accepted applications include inoperable disease due to tumour distribution or inadequate liver reserve. • Other current indications include concurrent co-morbidity, patient choice and the test-of-time approach. • Future applications may include resectable disease, e.g. for small solitary tumours.

Digital, online, and other electronic technology has transformed the nature of social work practice. Contemporary social workers can provide services to clients by using online counseling, telephone counseling, video counseling, cybertherapy (avatar therapy), self-guided Web-based interventions, electronic social networks, e-mail, and text messages. The introduction of diverse digital, online, and other forms of electronic social services has created a wide range of complex ethical and related risk management issues. This article provides an overview of current digital, online, and electronic social work services; identifies compelling ethical issues related to practitioner competence, client privacy and confidentiality, informed consent, conflicts of interest, boundaries and dual relationships, consultation and client referral, termination and interruption of services, documentation, and research evidence; and offers practical risk management strategies designed to protect clients and social workers. The author identifies relevant standards from the NASW Code of Ethics and other resources designed to guide practice.

Children of Latino immigrants, many of whom live in “mixed-status” families, are a rapidly growing group in the United States. It is widely accepted that their development is affected by multiple and complex factors, including those in their distal context (e.g., laws, institutions, policies). Despite the enormity of the deportation system and its vigorous implementation in recent years, little research has investigated how this particular component of the distal context affects Latino immigrant families. The present survey was designed to statistically explore the impact of detention/deportation on Latino immigrant parents and children ( N = 132). Regression analyses indicated that (1) parents with higher levels of legal vulnerability report a greater impact of detention/ deportation on the family environment (parent emotional well-being, ability to provide financially, and relationships with their children) and children’s well-being (child’s emotional well-being and academic performance) and (2) parents’ legal vulnerability and the impact of detention/deportation on the family predict outcomes for children. Implications for practice and policy are discussed.

An attitude scale was constructed using the method of summated ratings. The scale was used to investigate the effect of selected institutional variables on the attitude of the regular-classroom teacher toward mainstreaming special-needs children. The scale was administered to a sample of nearly 1,000 public school teachers in the 6 New England states. A stepwise multiple regression analysis was used to investigate the effect of the institutional variables on teacher's attitude toward mainstreaming. Results of the analyses indicated that of the 7 variables considered, the regular-classroom teacher's perception of degree of success in dealing with special-needs students had the most significant relationship to teacher attitude.

Importance: Prolonged opioid use after surgery may be associated with opioid dependency and increased health care use. However, published studies have reported varying estimates of the magnitude of prolonged opioid use and risk factors associated with the transition of patients to long-term opioid use. Objectives: To evaluate the rate and characteristics of patient-level risk factors associated with increased risk of prolonged use of opioids after surgery. Data Sources: For this systematic review and meta-analysis, a search of MEDLINE, Embase, and Google Scholar from inception to August 30, 2017, was performed, with an updated search performed on June 30, 2019. Key words may include opioid analgesics, general surgery, surgical procedures, persistent opioid use, and postoperative pain. Study Selection: Of 7534 articles reviewed, 33 studies were included. Studies were included if they involved participants 18 years or older, evaluated opioid use 3 or more months after surgery, and reported the rate and adjusted risk factors associated with prolonged opioid use after surgery. Data Extraction and Synthesis: The Meta-analysis of Observational Studies in Epidemiology (MOOSE) and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines were followed. Two reviewers independently assessed and extracted the relevant data. Main Outcomes and Measures: The weighted pooled rate and odds ratios (ORs) of risk factors were calculated using the random-effects model. Results: The 33 studies included 1 922 743 individuals, with 1 854 006 (96.4%) from the US. In studies with available sex and age information, participants were mostly female (1 031 399; 82.7%) and had a mean (SD) age of 59.3 (12.8) years. The pooled rate of prolonged opioid use after surgery was 6.7% (95% CI, 4.5%-9.8%) but decreased to 1.2% (95% CI, 0.4%-3.9%) in restricted analyses involving only opioid-naive participants at baseline. The risk factors with the strongest associations with prolonged opioid use included preoperative use of opioids (OR, 5.32; 95% CI, 2.94-9.64) or illicit cocaine (OR, 4.34; 95% CI, 1.50-12.58) and a preoperative diagnosis of back pain (OR, 2.05; 95% CI, 1.63-2.58). No significant differences were observed with various study-level factors, including a comparison of major vs minor surgical procedures (pooled rate: 7.0%; 95% CI, 4.9%-9.9% vs 11.1%; 95% CI, 6.0%-19.4%; P = .20). Across all of our analyses, there was substantial variability because of heterogeneity instead of sampling error. Conclusions and Relevance: The findings suggest that prolonged opioid use after surgery may be a substantial burden to public health. It appears that strategies, such as proactively screening for at-risk individuals, should be prioritized.

Nuclear and mitochondrial genomes are under continuous assault by a combination of environmentally and endogenously derived reactive oxygen species, inducing the formation and accumulation of mutagenic, toxic, and/or genome-destabilizing DNA lesions. Failure to resolve these lesions through one or more DNA-repair processes is associated with genome instability, mitochondrial dysfunction, neurodegeneration, inflammation, aging, and cancer, emphasizing the importance of characterizing the pathways and proteins involved in the repair of oxidative DNA damage. This review focuses on the repair of oxidative damage-induced lesions in nuclear and mitochondrial DNA mediated by the base excision repair (BER) pathway in mammalian cells. We discuss the multiple BER subpathways that are initiated by one of 11 different DNA glycosylases of three subtypes: (a) bifunctional with an associated β-lyase activity; (b) monofunctional; and (c) bifunctional with an associated β,δ-lyase activity. These three subtypes of DNA glycosylases all initiate BER but yield different chemical intermediates and hence different BER complexes to complete repair. Additionally, we briefly summarize alternate repair events mediated by BER proteins and the role of BER in the repair of mitochondrial DNA damage induced by ROS. Finally, we discuss the relation of BER and oxidative DNA damage in the onset of human disease.

Consensus refers to the extent to which judges agree in their ratings of a common target. Consensus has been an important area of research in social and personality psychology. In this article, generalizability theory is used to develop a percentage of total variance measure of consensus. This measure is used to review the level of consensus across 32 studies by considering the role of acquaintance level and trait dimension. The review indicates that consensus correlations ranged from zero to about .3, with higher levels of consensus for ratings of Extraversion. The studies do not provide evidence that consensus increases with increasing acquaintance, a counterintuitive result that can be accounted for by a theoretical model (D.A. Kenny, 1991, in press). Problems in the interpretation of longitudinal research are reviewed.

The wide-ranging varieties of capitalism literature rests on a particular conception of banks and banking that, the authors argue, no longer reflects the reality of modern financial systems. They take advantage of the greater information regarding bank activities revealed by the financial crisis to consider the reality, across eight of the world's largest developed economies, of the financial power of banks to act as bulwarks against market forces. This article offers a market-based banking framework that transcends the bank-based/capital market–based dichotomy that dominates comparative political economy's consideration of financial systems and argues that future CPE research should focus on the activities of banks. By demonstrating how market-based banking increases market influences on the supply of credit, the authors highlight an underap-preciated source of financial market pressure on nonfinancial companies (NFCs) that can have a potential impact across the range of issues that the varieties of capitalism (VoC) literature has seen as differentiating national systems. This approach has implications in areas such as labor, welfare, innovation, and flexibility.

The Park City Math Institute 2016 Summer Undergraduate Faculty Program met for the purpose of composing guidelines for undergraduate programs in data science. The group consisted of 25 undergraduate faculty from a variety of institutions in the United States, primarily from the disciplines of mathematics, statistics, and computer science. These guidelines are meant to provide some structure for institutions planning for or revising a major in data science.

Professional learning communities have become one of the most talked about ideas in education today. Many K-12 schools are working to become professional learning communities in the hope that student learning will improve when adults commit themselves to talking collaboratively about teaching and learning and then take action that will improve student learning and achievement. The researchers in this study believe that a school must understand and practice the five disciplines of a learning organization to be a true professional learning community and that leadership plays a significant role in the ability of a school to become a professional learning community that enhances student learning. The questions explored in this study of six middle schools, three urban and three suburban, were: 1) What does a professional learning community look like in a middle school? 2) What kind of principal creates a professional learning community in his/her school? 3) What are the beliefs and dispositions of such a leader? 4) Do teachers perceive their school to be a professional learning community? and, 5) Is there a relationship between professional learning communities, leadership, and student learning?
