Negative parenting is shaped by the genetically-influenced characteristics of children (via evocative rGE) and by parental antisocial behavior, however, it is unclear how these factors jointly impact parenting. The current study examined the effects of birth parent and adoptive parent antisocial behavior on negative parenting. Participants included 546 families within a prospective adoption study. Adoptive parent antisocial behavior emerged as a small but significant predictor of negative parenting at 18 months and of change in parenting from 18 to 27 months. Birth parent antisocial behavior predicted change in adoptive father’s (but not mother’s) parenting over time. These findings highlight the role of parent characteristics and suggest that evocative rGE effects on parenting may be small in magnitude in early childhood. PMID:27716897

Land ownership and technology adoption revisited: Improved maize varieties in Ethiopia.

The lack of land ownership can discourage agricultural technology adoption, yet there is scarce evidence of the impact of land rental contracts on the adoption of improved crop varieties in developing countries. The current study investigates such impact using a nationally representative survey of Ethiopian maize farmers. In contrast to many previous studies, we show in a simple model that cash-renters are as likely to adopt improved maize varieties as owner-operators, while sharecroppers are more likely to adopt given that such varieties are profitable. Empirical analysis reveals a significant impact of sharecropping on improved maize variety adoption, and no significant impact from cash-rental, lending support to the above hypotheses. These results imply that improvements in land rental markets can potentially enhance household welfare through crop variety adoption in agrarian economies where land sales markets are incomplete or missing.

Adoption of Injectable Naltrexone in U.S. Substance Use Disorder Treatment Programs

PubMed Central

Aletraris, Lydia; Edmond, Mary Bond; Roman, Paul M

2015-01-01

Objective: Medication-assisted treatment for substance use disorders (SUDs) is not widely used in treatment programs. The aims of the current study were to document the prevalence of adoption and implementation of extended-release injectable naltrexone, the newest U.S. Food and Drug Administration–approved medication for alcohol use disorder (AUD), in U.S. treatment programs and to examine associations between organizational and patient characteristics and adoption. Method: The study used interview data from a nationally representative sample of 307 U.S. SUD treatment programs to examine adoption and implementation of injectable naltrexone. Results: Thirteen percent of programs used injectable naltrexone for AUD, and 3% of programs used it for opioid use disorder. Every treatment program that offered injectable naltrexone to its patients used it in conjunction with psychosocial treatment, particularly cognitive behavioral therapy. Multivariate logistic regression results indicated that adoption was positively associated with the provision of wraparound services, the percentage of privately insured patients, and the presence of inpatient detoxification services. For-profit status and offering inpatient services were negatively associated with adoption. Within adopting programs, an average of 4.1% of AUD patients and 7.1% of patients with opioid use disorder were currently receiving the medication, despite clinical directors’ reports of positive patient outcomes, particularly for relapsers and for those who had been noncompliant with other medications. Cost was a significant issue for the majority of adopting organizations. Conclusions: The rate of adoption of injectable naltrexone in U.S. treatment programs remains limited. Researchers should continue to examine patient, organizational, and external characteristics associated with the adoption and implementation of injectable naltrexone over time. PMID:25486403

Little work has examined relationship dissolution or divorce in adoptive parents or same-sex parent couples. The current study examined predictors of relationship dissolution across the first 5 years of parenthood among a sample of heterosexual, lesbian, and gay male adoptive couples. Of the 190 couples in the study, 15 (7.9%) dissolved their relationships during the first 5 years of adoptive parenthood. Specifically, 7 of 57 lesbian couples (12.3%), 1 of 49 gay male couples (2.0%), and 7 of 84 heterosexual couples (8.3%) dissolved their unions. Results of our logistic regression analysis revealed that the odds of relationship dissolution were significantly higher for (a) couples who adopted a non-infant (i.e., older) child); (b) participants who reported feeling less prepared for the adoption, three months post-adoptive placement; and (c) couples in which both partners reported very low, or very high, pre-adoption levels of relationship maintenance behaviors. Findings have implications for adoption professionals seeking to support same-sex and heterosexual prospective adopters, as well as societal debates and policy regarding same-sex relationships and parenting.

2017-01-01

This paper presents preliminary research findings on the ICT adoption framework for education. Despite many studies have been conducted on ICT adoption framework in education at various countries, they are lack of analysis on the degree of component contribution to the success to the framework. In this paper a set of components that link to ICT adoption in education is observed based on literatures and explorative analysis. The components are Infrastructure, Application, User Skills, Utilization, Finance, and Policy. The components are used as a basis to develop a questionnaire to capture the current ICT adoption condition in schools. The data from questionnaire are processed using Structured Equation Model (SEM). The results show that each component contributes differently to the ICT adoption framework. Finance provides the strongest affect to Infrastructure readiness, whilst User Skills provides the strongest affect to Utilization. The study concludes that development of ICT adoption framework should consider components contribution weights among the components that can be used to guide the implementation of ICT adoption in education.

Adoption and use of e-invoicing in Greece

NASA Astrophysics Data System (ADS)

Marinagi, C.; Trivellas, P.; Reklitis, Panagiotis; Skourlas, C.

2015-02-01

This paper investigates the adoption and use of electronic invoices (e-invoices) in Greek organizations. The study attempts to evaluate current practices applied in implementing e-invoicing. A field research has been conducted, which is based on a structured questionnaire. The target sample consisted of 42 Greek enterprises. The main issues of the investigation include the existing invoice processing practices, the barriers that prevent the extended adoption and use of e-invoicing, the observed benefits from e-invoicing implementation, and the strategic drivers for transition to e-invoicing. Currently, the use of e-invoicing in Greece is low. However, the research results testify that the adoption of e-invoicing in Greece is promising. Even though, a number of enterprises state that benefits of e-invoicing are not clear yet, the majority of enterprises agree that there are crucial financial priorities that e-invoicing is expected to support.

Twins and virtual twins: Do genetic (as well as experiential) factors affect developmental risks?

PubMed

Segal, Nancy L; Tan, Tony Xing; Graham, Jamie L

2015-08-01

Factors underlying developmental delays and psychosocial risks are of interest to international adoption communities. The current study administered a Pre-Adoption Adversity (PAA) Questionnaire to mostly American parents raising (a) adopted Chinese twins or (b) same-age unrelated adopted siblings. A goal was to replicate earlier analyses of pre-adoption adversity/adjustment among adopted preschool-age Chinese girls. A second goal was to conduct genetic analyses of four content areas (Developmental Delays at Adoption, Initial Adaptation to Adoption, Crying/Clinging, and Refusal/Avoidance) derived from the PAA Questionnaire. A key finding was that age at adoption added less than other predictors to adoptees' externalizing and internalizing behaviors. Family factors (e.g., parental education) contributed significantly to behavioral outcomes among the adopted Chinese twins. Genetic effects were indicated for all four content areas, with shared environmental effects evident for Developmental Delays at Adoption and Crying/Clinging. Future investigators should consider incorporating genetically sensitive designs into developmental research programs. Copyright © 2015 Elsevier Inc. All rights reserved.

Costs, Benefits, and Adoption of Additive Manufacturing: A Supply Chain Perspective

PubMed Central

Thomas, Douglas

2017-01-01

There are three primary aspects to the economics of additive manufacturing: measuring the value of goods produced, measuring the costs and benefits of using the technology, and estimating the adoption and diffusion of the technology. This paper provides an updated estimate of the value of goods produced. It then reviews the literature on additive manufacturing costs and identifies those instances in the literature where this technology is cost effective. The paper then goes on to propose an approach for examining and understanding the societal costs and benefits of this technology both from a monetary viewpoint and a resource consumption viewpoint. The final section discusses the trends in the adoption of additive manufacturing. Globally, there is an estimated $667 million in value added produced using additive manufacturing, which equates to 0.01 % of total global manufacturing value added. US value added is estimated as $241 million. Current research on additive manufacturing costs reveals that it is cost effective for manufacturing small batches with continued centralized production; however, with increased automation distributed production may become cost effective. Due to the complexities of measuring additive manufacturing costs and data limitations, current studies are limited in their scope. Many of the current studies examine the production of single parts and those that examine assemblies tend not to examine supply chain effects such as inventory and transportation costs along with decreased risk to supply disruption. The additive manufacturing system and the material costs constitute a significant portion of an additive manufactured product; however, these costs are declining over time. The current trends in costs and benefits have resulted in this technology representing 0.02 % of the relevant manufacturing industries in the US; however, as the costs of additive manufacturing systems decrease, this technology may become widely adopted and change the supplier, manufacturer, and consumer interactions. An examination in the adoption of additive manufacturing reveals that for this technology to exceed $4.4 billion in 2020, $16.0 billion in 2025, and $196.8 billion in 2035 it would need to deviate from its current trends of adoption.

The internet offers major opportunities in supporting mental health care, and a variety of technology-mediated mental and behavioral health services have been developed. Yet, despite growing evidence for the effectiveness of these services, their acceptance and use in clinical practice remains low. So far, the current literature still lacks a structured insight into the experienced drivers and barriers to the adoption of electronic mental health (eMental health) from the perspective of clinical psychologists. The aim of this study was to gain an in-depth and comprehensive understanding of the drivers and barriers for psychologists in adopting eMental health tools, adding to previous work by also assessing drivers and analyzing relationships among these factors, and subsequently by developing a structured representation of the obtained findings. The study adopted a qualitative descriptive approach consisting of in-depth semistructured interviews with clinical psychologists working in the Netherlands (N=12). On the basis of the findings, a model was constructed that was then examined through a communicative validation. In general, a key driver for psychologists to adopt eMental health is the belief and experience that it can be beneficial to them or their clients. Perceived advantages that are novel to literature include the acceleration of the treatment process, increased intimacy of the therapeutic relationship, and new treatment possibilities due to eMental health. More importantly, a relation was found between the extent to which psychologists have adopted eMental health and the particular drivers and barriers they experience. This differentiation is incorporated in the Levels of Adoption of eMental Health (LAMH) model that was developed during this study to provide a structured representation of the factors that influence the adoption of eMental health. The study identified both barriers and drivers, several of which are new to the literature and found a relationship between the nature and importance of the various drivers and barriers perceived by psychologists and the extent to which they have adopted eMental health. These findings were structured in a conceptual model to further enhance the current understanding. The LAMH model facilitates further research on the process of adopting eMental health, which will subsequently enable targeted recommendations with respect to technology, training, and clinical practice to ensure that mental health care professionals as well as their clients will benefit optimally from the current (and future) range of available eMental health options. ©Milou A Feijt, Yvonne AW de Kort, Inge MB Bongers, Wijnand A IJsselsteijn.

Schönwetter, D; Reynolds, P

2013-02-01

Given the exponential explosion of online learning tools and the challenge to harness their influence in dental education, there is a need to determine the current status of online learning tools being adopted at dental schools, the barriers that thwart the potential of adopting these and to capture this information from each of the various stakeholders involved in dental online learning (administrators, instructors, students and software/hardware technicians). The aims of this exploratory study are threefold: first, to understand which online learning tools are currently being adopted at dental schools; second, to determine the barriers in adopting online learning in dental education; and third, to identify a way of better preparing stakeholders in their quest to encourage others at their institutions to adopt online learning tools. Seventy-two participants representing eight countries and 13 stakeholder groups in dentistry were invited to complete the online Survey of Barriers in Online Learning Education in Health Professional Schools. The survey was created for this study but generic to all healthcare education domains. Twenty participants completed the survey. demonstrated that many online learning tools are being successfully adopted at dental schools, but computer-based assessment tools are the least successful. Added to this are challenges of support and resources for online learning tools. Participants offered suggestions of creating a blended (online and face-to-face) tutorial aimed at assisting stakeholders to help their dental schools in adopting online learning tools The information from this study is essential in helping us to better prepare the next generation of dental providers in terms of adopting online learning tools. This paper will not only provide strategies of how best to proceed, but also inspire participants with the necessary tools to move forward as they assist their clients with adopting and sustaining online learning tools and models. © 2012 John Wiley & Sons A/S.

Goldberg, Abbie E.; Smith, JuliAnna Z.; Kashy, Deborah A.

2010-01-01

The current study examined pre-adoptive factors as predictors of relationship quality (love, ambivalence, and conflict) among 125 couples (44 lesbian couples, 30 gay couples, and 51 heterosexual couples) across the first year of adoptive parenthood. On average, all new parents experienced declines in their relationship quality across the first year of parenthood, regardless of sexual orientation, with women experiencing steeper declines in love. Parents who, pre-adoption, reported higher levels of depression, greater use of avoidant coping, lower levels of relationship maintenance behaviors, and less satisfaction with their adoption agencies reported lower relationship quality at the time of the adoption. The effect of avoidant coping on relationship quality varied by gender. Parents who, pre-adoption, reported higher levels of depression, greater use of confrontative coping, and higher levels of relationship maintenance behaviors reported greater declines in relationship quality. These findings have implications for professionals who work with adoptive parents both pre- and post-adoption. PMID:20545395

The current longitudinal study examined trajectories of child negative emotionality, parenting efficacy, and overreactive parenting among 382 adoptive families during infancy and toddlerhood. Data were collected from adoptive parents when the children were 9, 18, and 27 months old. Latent growth curve modeling indicated age-related increases in child negative emotionality and overreactive parenting for adoptive fathers and adoptive mothers, and decreases in parent efficacy among adoptive mothers. Increases in child negative emotionality were also associated with increases in parent overreactivity and decreases in maternal efficacy. Mothers' and fathers' developmental patterns were linked within but not across parenting domains. Limitations and directions for future research are discussed. PMID:21883160

Process analytical technology in the pharmaceutical industry: a toolkit for continuous improvement.

PubMed

Scott, Bradley; Wilcock, Anne

2006-01-01

Process analytical technology (PAT) refers to a series of tools used to ensure that quality is built into products while at the same time improving the understanding of processes, increasing efficiency, and decreasing costs. It has not been widely adopted by the pharmaceutical industry. As the setting for this paper, the current pharmaceutical manufacturing paradigm and PAT guidance to date are discussed prior to the review of PAT principles and tools, benefits, and challenges. The PAT toolkit contains process analyzers, multivariate analysis tools, process control tools, and continuous improvement/knowledge management/information technology systems. The integration and implementation of these tools is complex, and has resulted in uncertainty with respect to both regulation and validation. The paucity of staff knowledgeable in this area may complicate adoption. Studies to quantitate the benefits resulting from the adoption of PAT within the pharmaceutical industry would be a valuable addition to the qualitative studies that are currently available.

Proximal antecedents and correlates of adopted error approach: a self-regulatory perspective.

PubMed

Van Dyck, Cathy; Van Hooft, Edwin; De Gilder, Dick; Liesveld, Lillian

2010-01-01

The current study aims to further investigate earlier established advantages of an error mastery approach over an error aversion approach. The two main purposes of the study relate to (1) self-regulatory traits (i.e., goal orientation and action-state orientation) that may predict which error approach (mastery or aversion) is adopted, and (2) proximal, psychological processes (i.e., self-focused attention and failure attribution) that relate to adopted error approach. In the current study participants' goal orientation and action-state orientation were assessed, after which they worked on an error-prone task. Results show that learning goal orientation related to error mastery, while state orientation related to error aversion. Under a mastery approach, error occurrence did not result in cognitive resources "wasted" on self-consciousness. Rather, attention went to internal-unstable, thus controllable, improvement oriented causes of error. Participants that had adopted an aversion approach, in contrast, experienced heightened self-consciousness and attributed failure to internal-stable or external causes. These results imply that when working on an error-prone task, people should be stimulated to take on a mastery rather than an aversion approach towards errors.

Predictors of relationship dissolution in lesbian, gay, and heterosexual adoptive parents.

Goldberg, Abbie E; Garcia, Randi

2015-06-01

Little work has examined relationship dissolution or divorce in adoptive parents or same-sex parent couples. The current study examined predictors of relationship dissolution across the first 5 years of parenthood among a sample of heterosexual, lesbian, and gay male adoptive couples. Of the 190 couples in the study, 15 (7.9%) dissolved their relationships during the first 5 years of adoptive parenthood. Specifically, 7 of 57 lesbian couples (12.3%), 1 of 49 gay male couples (2.0%), and 7 of 84 heterosexual couples (8.3%) dissolved their unions. Results of our logistic regression analysis revealed that the odds of relationship dissolution were significantly higher for (a) couples who adopted a noninfant (i.e., older child); (b) participants who reported feeling less prepared for the adoption, 3 months postadoptive placement; and (c) couples in which both partners reported very low or very high preadoption levels of relationship maintenance behaviors. Findings have implications for adoption professionals seeking to support same-sex and heterosexual prospective adopters, as well as societal debates and policy regarding same-sex relationships and parenting.

This study examined teen mothers' romanticism and self-esteem. The Dean Romanticism Scale and the Bachman Self-esteem Scale were administered to 94 mothers between the ages of 13 and 18 in Southern California. The study also investigated the relationship between the dependent variables--romanticism and self-esteem--and ten independent variables--age, age of mother when first child was born, incidence of sexual abuse, incidence of abortion, current sexual activity, adoption considerations, current use of birth control, whether paternity was denied by the baby's father, whether the mother's parents were living together, and the quality of the relationship between the mother's parents. Results indicated that five variables were significantly related to romanticism--whether the teenager had a previous abortion, adoption considerations, current sexual activity, whether the parents were living together, and the quality of the relationship between the parents. Two variables were significantly related to self-esteem--age and current use of birth control.

The dynamics of de-adoption: a case study of policy change, de-adoption, and replacement of an evidence-based HIV intervention.

McKay, Virginia R; Margaret Dolcini, M; Hoffer, Lee D

2017-12-01

Evidence-based intervention (EBI) de-adoption and its influence on public health organizations are largely unexplored within public health implementation research. However, a recent shift in support for HIV prevention EBIs by the Centers for Disease Control and Prevention provides an opportunity to explore EBI de-adoption. The current mixed-method study examines EBI de-adoption and the subsequent impact on a community-based organization (CBO) dedicated to HIV prevention. We conducted a case study with a CBO implementing RESPECT, an HIV prevention EBI, over 5 years (2010-2014), but then de-adopted the intervention. We collected archival data documenting RESPECT implementation and conducted two semi-structured interviews with RESPECT staff (N = 5). Using Fixsen and colleagues' implementation framework, we developed a narrative of RESPECT implementation, delivery, and de-adoption and a thematic analysis to understand additional consequences of RESPECT de-adoption. Discontinuation of RESPECT activities unfolded in a process over time, requiring effort by RESPECT staff. RESPECT de-adoption had wide-reaching influences on individual staff, interactions between the staff and the community, the agency overall, and for implementation of future EBIs. We propose a revision of the implementation framework, incorporating EBI de-adoption as a phase of the implementation cycle. Furthermore, EBI de-adoption may have important, unintended consequences and can inform future HIV prevention strategies and guide research focusing on EBI de-adoption.

Predicting re-involvement for children adopted out of a public child welfare system.

PubMed

Orsi, Rebecca

2015-01-01

Some of the approximately 400,000 children currently placed out-of-home in a public child welfare system will not reunify with their family of origin. They may instead be adopted into a new family. Adoption placements can be characterized by poor adjustment for children; some such placements even result in disruption or dissolution. We conducted a stratified Cox regression of 4,016 children from the Colorado public child welfare system. All of the children had a finalized adoption during the years 2002 through 2006. The two outcomes analyzed were new child protection and youth-in-conflict referrals and assessments for these previously adopted children. New child welfare referrals and assessments may be early indicators of poor adjustment for adopted children within the adoptive family. Study results indicate that older children and Hispanic children had higher rates of referral and assessment. Children with a pre-adoption history including longer time out-of-home or a larger number of out-of-home placements also experienced higher referral and assessment rates. Additional factors which predicted subsequent system re-involvement included presence of paid adoption assistance, adoption by a non-relative foster parent and younger adoptive parent age. Several study results were moderated by the presence or absence of an ethnic match between the child and the adoptive parents. We provide an overview of the statistical model used for analysis and we discuss implications of the study results for child welfare practice. Copyright © 2014 Elsevier Ltd. All rights reserved.

A matter of attachment? How adoptive parents foster post-institutionalized children's social and emotional adjustment.

PubMed

Barone, Lavinia; Lionetti, Francesca; Green, Jonathan

2017-08-01

The current study investigates the contribution of children's age at adoption (M = 46.52 months, SD = 11.52 months) and parents' attachment on post-institutionalized children's attachment and social-emotional adjustment. A total of 132 subjects, 48 post-institutionalized children aged 3-5 years, and their adoptive parents, took part in the study. One year from adoption, children's attachment distribution was as follows: 31% secure, 42% disorganized, and 27% insecure. Parents' secure attachment increased children's probability of presenting a secure attachment pattern; specifically, mothers' attachment patterns were most strongly associated with those of their adopted children, with fathers' making an additional contribution. Two years from adoption, secure children showed more adequate social competences than their insecure and disorganized peers and presented better emotional comprehension. The effect of age at adoption was delimited to a marginal association with behavioral problems. This pattern of associations suggests that attachment - both of adoptive parents and of children - substantially fosters social-emotional adjustment of post-institutionalized children who have experienced a period in emotionally neglecting environments beyond their first year of life, regardless of their age at adoption. Implications for policies and practices are discussed.

Aggarwal, Neil Krishan; Cedeno, Kryst; John, Dolly; Lewis-Fernandez, Roberto

2017-08-01

This study reports the extent to which states have adopted the national culturally and linguistically appropriate services (CLAS) standards. Officials from public mental health agencies in the 50 states, Washington, D.C., and Puerto Rico were contacted between January and June 2016 to obtain information about adoption of CLAS standards in current policies. Each policy was coded through thematic analysis to determine its correspondence with any of the 14 national CLAS standards, which are grouped into three domains. Officials from 47 states and territories (90%) responded. Eight states (17%) reported adopting all national CLAS standards. Ten (23%) had adopted no CLAS policies, five (12%) had adopted policies under one domain, three (7%) under two domains, and 25 (58%) under all three domains. Most states do not have policies that meet all CLAS standards, raising questions about how CLAS standards should be adopted.

Confirmatory evidence for a multidimensional model of racial-ethnic socialization for transracially adoptive families.

Langrehr, Kimberly J; Thomas, Anita Jones; Morgan, Sydney K

2016-07-01

The purpose of the current study is to test a recently established model of racial-ethnic socialization (Langrehr, 2014) among 2 samples of White transracially adoptive parents and to assess whether the proposed model functions similarly after accounting for adopted child race. Based on a modified version of the Racial Bias Preparation Scale (Fisher, Wallace, & Fenton, 2000), confirmatory factor analysis was used to test the 3-factor model (i.e., Prejudice Awareness, Racial-Ethnic Pride, and Egalitarianism) among 172 White transracially adoptive parents with Asian children (Mage = 45.72) and 140 White transracially adoptive parents with Black children (Mage = 42.62). In addition, multigroup invariance testing was used to assess whether the proposed model functioned similarly across the 2 groups of parents. Results indicate that the proposed 3-factor model demonstrated partial measurement invariance such that the subconstruct of Egalitarianism functioned similarly across groups, whereas Racial-Ethnic Pride and Prejudice Awareness were deemed noninvariant. Findings are intended to help expand the concept of racial-ethnic socialization for transracially adoptive families and address the degree to which current research on racial-ethnic socialization can be applied to different transracially adoptive families. Results are intended to highlight ways that various social-cultural dimensions of family can culminate into different socialization experiences.

Lin, Julia Ying-Chao; Wang, Edward Shih-Tse; Kao, Leticia L Y; Cheng, Julian Ming-Sung

2007-12-01

The potential of online games to become a major global business and the existence of limited related references led to the current study. In this study, Rogers's diffusion of innovation (DOI) theory is applied to investigate the principles for the adoption of online games in Taiwan. The findings suggest that relative advantages and compatibility both have a significant effect on the adoption of online games for purposes of amusement, with the former being more important for early gamers and the latter being regarded as more critical for later gamers. In addition, complexity is found to impede online game diffusion and is regarded as the most important facilitator.

Tarullo, Amanda R.; Garvin, Melissa C.; Gunnar, Megan R.

2012-01-01

While effects of institutional care on behavioral development have been studied extensively, effects on neural systems underlying these socioemotional and attention deficits are only beginning to be examined. The current study assessed electroencephalogram (EEG) power in 18-month-old internationally adopted, post-institutionalized children (n = 37) and comparison groups of non-adopted children (n = 47) and children internationally adopted from foster care (n = 39). For their age, post-institutionalized children had an atypical EEG power distribution, with relative power concentrated in lower frequency bands compared to non-adopted children. Both internationally adopted groups had lower absolute alpha power than non-adopted children. EEG power was not related to growth at adoption or to global cognitive ability. Atypical EEG power distribution at 18 months predicted indiscriminate friendliness and poorer inhibitory control at 36 months. Both post-institutionalized and foster care children were more likely than non-adopted children to exhibit indiscriminate friendliness. Results are consistent with a cortical hypoactivation model of the effects of early deprivation on neural development and provide initial evidence associating this atypical EEG pattern with indiscriminate friendliness. Outcomes observed in the foster care children raise questions about the specificity of institutional rearing as a risk factor and emphasize the need for broader consideration of the effects of early deprivation and disruptions in care.

Legal decisions concerning adoption taken over the last thirty years have usually followed changes in public opinion. For instance, the July 11 1966 Act has practically put an end to conflicts between adopting parents and biologic mothers (or parents) and has specified adoption eligibility criteria. At present, because most adoptions are successful and numbers of children eligible for adoption are falling steadily, efforts are being made to allow the adoption of the greatest possible number of children at a young age; some handicapped children as well as older children are also considered as adoptable. Older children who were neglected in their former environment occasionally experience psychologic problems; for them, decisions can be taken only individually and foster home placement with the potential adoptive parents can be used as a first step. Today, the practitioner's role is mainly to inform the adoptive parents on the impact of a given somatic or (if possible) psychologic handicap. The current tendency is to maintain the greatest possible number of children within their family environment by supporting the family and allowing the child and parents to participate in all the decisions concerning them. Adoption of French children is becoming more and more difficult, explaining why foreign-born children are being increasingly adopted.

Prevalence of anaesthesia information management systems in university-affiliated hospitals in Europe.

An increasing number of studies suggest that anaesthesia information management systems (AIMS) improve clinical care. The purpose of this web survey study was to assess the prevalence of AIMS in European university-affiliated anaesthesia departments and to identify the motivations for and barriers to AIMS adoption. A survey was e-mailed to 252 academic anaesthesia chairs of 294 university-affiliated hospitals in 22 European countries, with 41 e-mails returned as undeliverable, leaving the final sample equal to 211. Responders provided information on demographics, the other information technology systems available in their hospitals, and current implementation status of AIMS. Adopters were asked about motivations for installing AIMS, whereas nonadopters were asked about barriers to AIMS adoption. Eighty-six (29%) of 294 hospitals responded. Forty-four of the 86 departments (51%) were considered AIMS adopters because they were already using (n = 15), implementing (n = 13) or selecting an AIMS (n = 16). The 42 remaining departments (49%) were considered nonadopters as they were not expecting to install an AIMS owing to lack of funds (n = 27), other reasons (n = 13) such as lack of support from the information technology department, or simply did not have a plan (n = 2). The top ranked motivators for adopting AIMS were improved clinical documentation, improvement in patient care and safety, and convenience for anaesthesiologists. AIMS adopters were more likely than nonadopters to already have other information technology systems deployed throughout the hospital. At least 44 (or 15%) of the 294 university-affiliated departments surveyed in this study have already implemented, are implementing, or are currently selecting an AIMS. The main barrier identified by AIMS nonadopters is lack of funds.

On the dual equivalence of the self-dual and topologically massive /p-form models

We study the duality symmetry in p-form models containing a generalized Bq∧Fp+1 term in spacetime manifolds of arbitrary dimensions. The equivalence between the Bq∧Fp+1 self-dual (SDB∧F) and the Bq∧Fp+1 topologically massive (TMB∧F) models is established using a gauge embedding procedure, including the minimal coupling to conserved charged matter current. The minimal coupling adopted for both tensor fields in the self-dual representation is transformed into a non-minimal magnetic like coupling in the topologically massive representation but with the currents swapped. It is known that to establish this equivalence a current-current interaction term is needed to render the matter sector unchanged. We show that both terms arise naturally from the embedding adopted. Comparison with Higgs/Julia-Toulouse duality is established.

Exposure to environmental tobacco smoke (ETS) constitutes a threat to the health of many people. In order to diminish ETS exposure, countries (including Poland) implemented legal restrictions of smoking in public places and worksites. Currently more attention is also paid to reduce overall and residential ETS exposure by voluntary smoke-free home policy adoption. The aim of current analysis was to evaluate the prevalence and determinants of implementing smoking bans at place of residence among economically active males and females in Poland. Data from cross-sectional, household study - Global Adult Tobacco Survey (GATS 2009-2010) were analyzed. The logistic regression model was applied for appropriate calculations. Out of 3696 studied subjects only 37.1% adopted total smoking ban within the home. Decreased likelihood of adopting total smoking bans was associated with current smoker status, low education attainment, lack of awareness on adverse health consequences of ETS, low level of support for tobacco control policies, and cohabitation with a smoker in both genders. Having smoke-free homes was also linked with age in women, place of residence and work smoking policy in indoor areas in men. Targeted activities to encourage adopting voluntary smoke-free rules among groups least likely to implement 100% smoking bans in the home and activities to decrease social acceptance of smoking in the presence of nonsmokers, children, pregnant woman are urgently needed.

Intimate Relationship Challenges in Early Parenthood among Lesbian, Gay, and Heterosexual Couples Adopting via the Child Welfare System

Goldberg, Abbie E.; Kinkler, Lori A.; Moyer, April M.; Weber, Elizabeth

2014-01-01

Little research has examined the transition to parenthood among couples who adopt through the child welfare system. The current qualitative study of 84 individuals within 42 couples (17 lesbian, 13 gay, and 12 heterosexual), who were placed with a child via foster care three months earlier, examined perceived changes in their intimate relationship. Findings indicated that, like heterosexual biological-parent couples, some adoptive parents perceived the loss of their partner’s undivided attention as stressful to the relationship. Adoption-specific stressors were also identified, including the need to find state-approved child care to facilitate “couple time” and the legal insecurity of foster-to-adopt placements. Although our findings were similar for heterosexual, lesbian, and gay adoptive parents, same-sex couples cited some additional stressors related to their sexual minority status. Findings have implications for individual, couple, and family practitioners who work with lesbian, gay, and heterosexual adoptive parents, particularly during their transition to parenthood.

2012-01-01

Children adopted from China currently represent the largest group of newly internationally adopted children in the US. An exploratory investigation of the communicative development of six young females adopted at ages 9 to 17 months from China by US families was conducted. Children were followed longitudinally from approximately three months post-adoption to age three years. English language skills were assessed at approximately three-month intervals, detailed communicative analyses were conducted at six months post-adoption, and outcomes were measured at three years of age. Results indicated wide variability in rates of English language development. Phonological, social-communicative, and lexical bases of communication were intact for each child at six months post-adoption. At age three years, four of the children demonstrated speech and language skills within one standard deviation of standardized test norms, one child demonstrated skills above the normal range, and one child’s skills were below the normal range. This study provides evidence of the resiliency of children’s language learning abilities. PMID:23204925

This paper investigates the adoption and use of electronic invoices (e-invoices) in Greek organizations. The study attempts to evaluate current practices applied in implementing e-invoicing. A field research has been conducted, which is based on a structured questionnaire. The target sample consisted of 42 Greek enterprises. The main issues of the investigation include the existing invoice processing practices, the barriers that prevent the extended adoption and use of e-invoicing, the observed benefits from e-invoicing implementation, and the strategic drivers for transition to e-invoicing. Currently, the use of e-invoicing in Greece is low. However, the research results testify that the adoptionmore » of e-invoicing in Greece is promising. Even though, a number of enterprises state that benefits of e-invoicing are not clear yet, the majority of enterprises agree that there are crucial financial priorities that e-invoicing is expected to support.« less

2012-01-01

Similar to biological mothers during the postpartum period, women who adopt children experience increased stress and life changes that may put them at risk for developing depression and anxiety. The purpose of the current study was to compare levels of depression and anxiety symptoms between postpartum and adoptive women and, among adoptive women, to examine associations between specific stressors and depressive symptoms. Data from adoptive mothers (n=147), recruited from Holt International, were compared to existing data from postpartum women (n=147). Differences in the level of depression and anxiety symptoms as measured by the Inventory of Depression and Anxiety Symptoms among postpartum and adoptive women were examined. Associations between specific stressors and depressive symptoms were examined among adoptive mothers. Postpartum and adoptive women had comparable levels of depressive symptoms, but adoptive women reported greater well-being and less anxiety than postpartum women. Stressors (e.g., sleep deprivation, history of infertility, past psychological disorder, and less marital satisfaction) were all significantly associated with depressive symptoms among adoptive women. The level of depressive symptoms was not significantly different between the two groups. In contrast, adoptive women experienced significantly fewer symptoms of anxiety and experienced greater well-being. Additionally, adoptive mothers experienced more depressive symptoms during the year following adoption when the stressors were present. Thus, women with these characteristics should be routinely screened for depression and anxiety. PMID:21725836

2015-02-01

Prior theoretical and empirical research suggests that multiple aspects of an organization's context are likely related to a number of factors, from their interest and ability to adopt new programming, to client outcomes. A limited amount of the prior research has taken a more community-wide perspective by examining factors that associate with community readiness for change, leaving how these findings generalize to community organizations that conduct prevention or positive youth development programs unknown. Thus for the current study, we examined how the organizational context of the Cooperative Extension System (CES) associates with current attitudes and practices regarding prevention and evidence-based programming. Attitudes and practices have been found in the empirical literature to be key indicators of an organization's readiness to adopt prevention and evidence-based programming. Based on multi-level mixed models, results indicate that organizational management practices distinct from program delivery may affect an organization's readiness to adopt and implement new prevention and evidence-based youth programs, thereby limiting the potential public health impact of evidence-based programs. Openness to change, openness of leadership, and communication were the strongest predictors identified within this study. An organization's morale was also found to be a strong predictor of an organization's readiness. The findings of the current study are discussed in terms of implications for prevention and intervention.

2009-01-01

The purpose of this study is to reassess the projected rate of Electronic Health Record (EHR) diffusion and examine how the federal government's efforts to promote the use of EHR technology have influenced physicians' willingness to adopt such systems. The study recreates and extends the analyses conducted by Ford et al. (1) The two periods examined come before and after the U.S. Federal Government's concerted activity to promote EHR adoption. Meta-analysis and bass modeling are used to compare EHR diffusion rates for two distinct periods of government activity. Very low levels of government activity to promote EHR diffusion marked the first period, before 2004. In 2004, the President of the United States called for a "Universal EHR Adoption" by 2014 (10 yrs), creating the major wave of activity and increased awareness of how EHRs will impact physicians' practices. EHR adoption parameters--external and internal coefficients of influence--are estimated using bass diffusion models and future adoption rates are projected. Comparing the EHR adoption rates before and after 2004 (2001-2004 and 2001-2007 respectively) indicate the physicians' resistance to adoption has increased during the second period. Based on current levels of adoption, less than half the physicians working in small practices will have implemented an EHR by 2014 (47.3%). The external forces driving EHR diffusion have grown in importance since 2004 relative to physicians' internal motivation to adopt such systems. Several national forces are likely contributing to the slowing pace of EHR diffusion.

How Static is the Statics Classroom? An investigation into how innovations, specifically Research-Based Instructional Strategies, are adopted into the Statics Classroom

NASA Astrophysics Data System (ADS)

Cutler, Stephanie Leigh

The purpose of this dissertation is to investigate how educational research, specifically Research-Based Instructional Strategies (RBIS), is adopted by education practice, specifically within the engineering Statics classroom. Using a systematic approach, changes in classroom teaching practices were investigated from the instructors' perspective. Both researchers and practitioners are included in the process, combining efforts to improve student learning, which is a critical goal for engineering education. The study is divided into 3 stages and each is discussed in an individual manuscript. Manuscript 1 provides an assessment of current teaching practices; Manuscript 2 explores RBIS use by Statics instructors and perceived barriers of adoption; and Manuscript 3 evaluates adoption using Fidelity of Implementation. A common set of concurrent mixed methods was used for each stage of this study. A quantitative national survey of Statics instructors (n =166) and 18 qualitative interviews were conducted to examine activities used in the Statics classroom and familiarity with nine RBIS. The results of this study show that lecturing is the most common activity throughout Statics classrooms, but is not the only activity. Other common activities included working examples and students working on problems individually and in groups. As discussed by the interview participants, each of Rogers' characteristics influenced adoption for different reasons. For example, Complexity (level of difficulty with implementation of an RBIS) was most commonly identified as a barrier. His study also evaluated the Fidelity of Implementation for each RBIS and found it to be higher for RBIS that were less complex (in terms of the number of critical components). Many of the critical components (i.e. activities required for implementation, as described in the literature) were found to statistically distinguish RBIS users and non-users. This dissertation offers four contributions: (1) an understanding of current practices in Statics; (2) the instructor perspective of the barriers to using RBIS in the classroom; (3) the use of Fidelity of Implementation as a unique evaluation of RBIS adoption, which can be used by future engineering education researchers; and (4) a systematic approach of exploring change in the classroom, which offers new perspectives and approaches to accelerate the adoption process.

Creating grander families: older adults adopting younger kin and nonkin.

PubMed

Hinterlong, James; Ryan, Scott

2008-08-01

There is a dearth of research on older adoptive parents caring for minor children, despite a growing number of such adoptions finalized each year. This study offers a large-scale investigation of adoptive families headed by older parents. We describe these families and explore how preadoptive kinship between the adoptive parent and the child impacts adoption outcomes. We analyze data from kin (n = 98) and nonkin (n = 310) adoptive families headed by adults aged 60 years and older. We find that older kin adoptive families are smaller, report lower income, and include adoptive mothers with less formal education. Children in these families had less severe needs for special care at the time of placement. Although kin and nonkin older parents offer similar assessments of their parent-child relationships, kin adopters indicate a greater willingness to adopt the same child again and yet report less positive current family functioning. Multivariate regression analyses reveal that preadoptive kinship predicts more negative parental assessment of the adoption's impact on the family and less positive family functioning net of other parent, family, and child characteristics. Externalizing behavior by the child (e.g., delinquency or aggression) is the strongest predictor of deleterious outcomes for both groups. Kin adoption by older adults creates new families under strain but does not reduce parental commitment to the child. We conclude that older adults serve as effective adoptive parents but would benefit from preadoption and postadoption services to assist them in preparing for and positively addressing the challenging behaviors exhibited by adopted children.

The Association between Parent-Child Conflict and Adolescent Conduct Problems over Time: Results from a Longitudinal Adoption Study

Klahr, Ashlea M.; McGue, Matt; Iacono, William G.; Burt, S. Alexandra

2010-01-01

A handful of prior adoption studies have confirmed that the cross-sectional relationship between child conduct problems and parent/child conflict is at least partially shared environmental in origin. However, as the direction of causation between parenting and delinquency remains unclear, this relationship could be better explained by the adolescent's propensity to elicit conflictive parenting, a phenomenon referred to as an evocative gene-environment correlation. The current study thus examined the prospective relationship between conduct problems and parent-child conflict in a sample of adoptive families. Participants included 672 adolescents in 405 adoptive families assessed at two time points roughly 4 years apart. Results indicated that parent-child conflict predicts the development of conduct problems, whereas conduct problems do not predict increases in parent-child conflict. Such findings suggest that evocative gene-environment correlations are highly unlikely as an explanation of prior shared environmental effects during adolescence. Moreover, because the adolescents in this study do not share genes with their adoptive parents, the association between conduct problems and parent-child conflict is indicative of shared environmental mediation in particular. Implications of our findings are discussed. PMID:21038930

Psychotic-like experiences (PLEs) or subclinical psychotic experiences have received increased attention as some studies have suggested continuity between PLEs and psychotic disorders. However, epidemiological and correlational studies of PLEs showed mixed findings - it is observed that different studies use a wide variety of definitions of PLEs, as well as different assessment tools that are designed to capture such described experiences. The differences in definitions and assessment tools adopted could contribute to the discrepancy of findings. The current review aims to examine the definitions and assessment tools adopted in the studies of PLEs. Literature search was conducted between October 2013 and February 2014 using three search engines: Medline, Web of Science and PubMed. A total of 76 papers met the selection criteria and were included in the current review. It is found that the majority of papers reviewed defined PLEs quantitatively using assessment tools and do not have a specific phenomenological definition, whereas assessment tools adopted have a wide variety. Furthermore, phenomenological studies of PLEs were rare. The variations in definitions and assessment tools of PLEs might contribute to mixed findings in researches. Reaching to a consensus through the study of phenomenology of PLEs is essential to further advancement of the research in this area. © 2015 Wiley Publishing Asia Pty Ltd.

Data from the 2011–2012 National Survey of Children’s Health and the 2013 National Survey of Children in Nonparental Care were used to fit a multinomial logistic model comparing three groups to those who never considered adoption: those who ever considered, but are not currently planning adoption; those planning adoption; and those who adopted. Adoption may be more likely when the caregiver is a nonkin foster parent, a foster care agency was involved, and/or financial assistance is available. Those with plans to adopt but who have not adopted may face adoption barriers such as extreme poverty, lower education and being unmarried. PMID:26949328

Artificial pancreas (AP) systems are currently an active field of diabetes research. This pilot study examined the attitudes of AP clinical trial participants toward future acceptance of the technology, having gained firsthand experience. After possible influencers of AP technology adoption were considered, a 34-question questionnaire was developed. The survey assessed current treatment satisfaction, dimensions of clinical trial participant motivation, and variables of the technology acceptance model (TAM). Forty-seven subjects were contacted to complete the survey. The reliability of the survey scales was tested using Cronbach's α. The relationship of the factors to the likelihood of AP technology adoption was explored using regression analysis. Thirty-six subjects (76.6%) completed the survey. Of the respondents, 86.1% were either highly likely or likely to adopt the technology once available. Reliability analysis of the survey dimensions revealed good internal consistency, with scores of >0.7 for current treatment satisfaction, convenience (motivation), personal health benefit (motivation), perceived ease of use (TAM), and perceived usefulness (TAM). Linear modeling showed that future acceptance of the AP was significantly associated with TAM and the motivation variables of convenience plus the individual item benefit to others (R(2)=0.26, P=0.05). When insulin pump and continuous glucose monitor use were added, the model significance improved (R(2)=0.37, P=0.02). This pilot study demonstrated that individuals with direct AP technology experience expressed high likelihood of future acceptance. Results support the factors of personal benefit, convenience, perceived usefulness, and perceived ease of use as reliable scales that suggest system adoption in this highly motivated patient population.

Few children meet physical activity (PA) recommendations, and are therefore at increased risk for overweight/obesity and adverse health outcomes. To increase children's opportunities for PA, several Canadian provinces have adopted school-based daily PA (DPA) policies. It is not clear why some jurisdictions have adopted DPA policies, and others have not, nor whether these policies have been implemented and have achieved their intended outcomes. The purpose of this study was to understand the processes underlying adoption and diffusion of Canadian DPA policies, and to review evidence regarding their implementation and impact. We adopted a multiple case history methodology in which we traced the chronological trajectory of DPA policies among Canadian provinces by compiling timelines detailing key historical events that preceded policy adoption. Publicly available documents posted on the internet were reviewed to characterize adopter innovativeness, describe the content of their DPA policies, and explore the context surrounding policy adoption. Diffusion of Innovations theory provided a conceptual framework for the analyses. A systematic literature search identified studies that had investigated adoption, diffusion, implementation or impact of Canadian DPA policies. Five of Canada's 13 provinces and territories (38.5%) have DPA policies. Although the underlying objectives of the policies are similar, there are clear differences among them and in their various policy trajectories. Adoption and diffusion of DPA policies were structured by the characteristics and capacities of adopters, the nature of their policies, and contextual factors. Limited data suggests implementation of DPA policies was moderate but inconsistent and that Canadian DPA policies have had little to no impact on school-aged children's PA levels or BMI. This study detailed the history and current status of Canadian DPA policies, highlighting the conditional nature of policy adoption and diffusion, and describing policy and adopter characteristics and political contexts that shaped policy trajectories. An understanding of the conditions associated with successful policy adoption and diffusion can help identify receptive contexts in which to pioneer novel legislative initiatives to increase PA among children. By reviewing evidence regarding policy implementation and impact, this study can also inform amendments to existing, and development of future PA policies.

Adoption of innovations, whether new ideas, technologies, or products, is crucially important to knowledge societies. The landmark studies of adoption dealt with innovations having great societal impact (such as antibiotics or hybrid crops) but where determining the utility of the innovation was straightforward (such as fewer side effects or greater yield). Recent large-scale studies of adoption were conducted within heterogeneous populations and focused on products with little societal impact. Here, we focus on a case with great practical significance: adoption by small groups of highly trained individuals of innovations with large societal impact but for which it is impractical to determine the true utility of the innovation. Specifically, we study experimentally the adoption by critical care physicians of a diagnostic assay that complements current protocols for the diagnosis of life-threatening bacterial infections and for which a physician cannot estimate the true accuracy of the assay based on personal experience. We show through computational modeling of the experiment that infection-spreading models—which have been formalized as generalized contagion processes—are not consistent with the experimental data, while a model inspired by opinion models is able to reproduce the empirical data. Our modeling approach enables us to investigate the efficacy of different intervention schemes on the rate and robustness of innovation adoption in the real world. While our study is focused on critical care physicians, our findings have implications for other settings in education, research, and business, where small groups of highly qualified peers make decisions about the adoption of innovations whose utility is difficult if not impossible to gauge.

Study on rejection characteristic of current loop to the base disturbance of optical communication system

Mao, Yao; Deng, Chao; Liu, Qiong; Cao, Zheng

2016-10-01

As laser has narrow transmitting beam and small divergence angle, the LOS (Line of Sight) stabilization of optical communication system is a primary precondition of laser communication links. Compound axis control is usually adopted in LOS stabilization of optical communication system, in which coarse tracking and fine tracking are included. Rejection against high frequency disturbance mainly depends on fine tracking LOS stabilization platform. Limited by different factors such as mechanical characteristic of the stabilization platform and bandwidth/noise of the sensor, the control bandwidth of LOS stabilization platform is restricted so that effective rejection of high frequency disturbance cannot be achieved as it mainly depends on the isolation characteristic of the platform itself. It is proposed by this paper that current loop may reject the effect of back-EMF. By adopting the method of electric control, high frequency isolation characteristic of the platform can be improved. The improvement effect is similar to increasing passive vibration reduction devices. Adopting the double closed loop control structure of velocity and current with the combining of the rejection effect of back-EMF caused by current loop is equivalent to reducing back-EMF coefficient, which can enhance the isolation ability of the LOS stabilization platform to high frequency disturbance.

Hybrid modelling for ATES planning and operation in the Utrecht city centre

NASA Astrophysics Data System (ADS)

Jaxa-Rozen, Marc; Bloemendal, Martin; Kwakkel, Jan; Rostampour, Vahab

2016-04-01

Aquifer Thermal Energy Storage (ATES) systems can significantly reduce the energy use and greenhouse gas emissions of buildings in temperate climates. However, the rapid adoption of these systems has evidenced a number of emergent issues with the operation and management of urban ATES systems, which require careful spatial planning to avoid thermal interferences or conflicts with other subsurface functions. These issues have become particularly relevant in the Netherlands, which are currently the leading market for ATES (Bloemendal et al., 2015). In some urban areas of the country, the adoption of ATES technology is thus becoming limited by the available subsurface space. This scarcity is partly caused by current approaches to ATES planning; as such, static permits tend to overestimate pumping rates and yield excessive safety margins, which in turn hamper the energy savings which could be realized by new systems. These aspects are strongly influenced by time-dependent dynamics for the adoption of ATES systems by building owners and operators, and by the variation of ATES well flows under uncertain conditions for building energy demand. In order to take these dynamics into account, previous research (Jaxa-Rozen et al., 2015) introduced a hybrid simulation architecture combining an agent-based model of ATES adoption, a Matlab control design, and a MODFLOW/SEAWAT aquifer model. This architecture was first used to study an idealized case of urban ATES development. This case evidenced a trade-off between the thermal efficiency of individual systems and the collective energy savings realized by ATES systems within a given area, which had already been suggested by other research (e.g. Sommer et al., 2015). These results also indicated that current layout guidelines may be overly conservative, and limit the adoption of new systems. The present study extends this approach to a case study of ATES planning in the city centre of Utrecht, in the Netherlands. This case is particularly relevant due to a combination of dense ATES development and complex subsurface conditions. An agent-based model of ATES adoption was thus parameterized to represent historical development patterns in the area over the 1998-2015 period, as well as plausible future adoption dynamics under a range of socio-technical uncertainties. An existing geohydrological model (Deltares, 2009) was used to represent local subsurface conditions. Preliminary results from this case study indicate that the idealized dynamics obtained in the previous case can also be observed under more realistic conditions; the geographic constraints introduced by building plot layouts and other spatial features tend to further constrain the adoption of new systems, emphasizing the risk of a scarcity of space under current layout guidelines. Furthermore, order effects appear to play a more significant role for system efficiency than in the idealized case. Earlier adopters thus tend to benefit from higher thermal efficiency due to the transient development of thermal bubbles, which could make older systems more robust to thermal interactions. In order to better understand the relationships between these processes and the operation of ATES wells under uncertainty, the case study will be extended by incorporating a Model Predictive Control approach for simulated ATES operation.

Babies born with clefts of the lip, and the alveolus or palate, or both, require multidisciplinary, highly specialised treatment from birth to early adulthood. We review the contemporary management of clefts and outline the current treatment protocol adopted by cleft networks in the United Kingdom. We also look at the level of evidence and the restructuring of services that has defined current practice. In light of the recent Cleft Care UK study, we ask whether it is now time to adopt a new philosophy towards the surgical techniques that are used.

Late-adoptions in adolescence: Can attachment and emotion regulation influence behaviour problems? A controlled study using a moderation approach.

PubMed

Pace, Cecilia Serena; Di Folco, Simona; Guerriero, Viviana

2018-03-01

A growing body of research suggests that, compared to normative adolescence, adoptive adolescence could be considered a specific risk condition characterized by more psychiatric problems, attachment insecurity, and emotional regulation difficulties as consequences of negative experiences in preadoption relationships. The current study explores (a) a moderation model of adoption status on the association between attachment representations (secure, dismissing, preoccupied, and disorganized) and behavioural problems and (b) a moderation model of adoption status on the association between emotion regulation processes (cognitive reappraisal and expressive suppression) and behavioural problems. Both the moderation models were controlled for verbal skills. Forty-six adopted adolescents and a control group of 34 nonadopted peers (12-16 years old) living with both their biological parents were assessed using the Friends and Family Interview, the Emotion Regulation Questionnaire for Children and Adolescents, the Child Behaviour Check List 6-18, and the verbal subtests of the Wechsler Intelligence Scale for Children, the latter as control measure. Results showed that adoption status (but not attachment) positively predicted externalizing and total behaviour problems, whereas attachment disorganization (but not adoption status) positively predicted internalizing problems in both group. Moreover, low cognitive reappraisal had a negative impact on externalizing problems only for adopted adolescents, but not for nonadopted youths. The clinical implications of these findings are discussed in order to enhance effective intervention with adopted adolescents and their parents. Copyright © 2017 John Wiley & Sons, Ltd.

More than just a question of technology: factors related to hospitals' adoption and implementation of health information exchange.

PubMed

Vest, Joshua R

2010-12-01

The provisions of the American Recovery & Reinvestment Act increased the likelihood of more widespread health information exchange (HIE), the electronic transfer of patient-level information between organizations, by essentially mandating the use of electronic health record systems. While important, the sparse body of research on HIE efforts and anecdotal reports indicate the barriers to HIE adoption and implementation include factors beyond simply the presence or absence of a specific technology. This paper examines those technological, organizational, and environmental factors that are associated with both HIE adoption and implementation in a sample of 4830 U.S. hospitals. Factors associated with adoption and implementation were modeled using random-intercept logistic regression. Consistent with a perspective that adoption and implementation are different phenomena, many factors associated with an increased odds of adoption, were unassociated with implementation and vice versa. Non-profit status, public hospitals, more live and operation applications, more emergency room visits, network membership, and the presence of physician portals all increased hospitals' odds of HIE adoption. However, only network membership increased the odds of HIE implementation, whereas competition decreased those odds significantly. This study agreed with earlier case-studies and anecdotal reports that factors beyond technology were important to both adoption and implementation. While current U.S. policy on healthcare information technology adoption focuses on technological barriers, many other non-technological factors may ultimately hinder effective HIE.

Agent-based modeling is commonly used for studying complex system properties emergent from interactions among many agents. We present a novel data-driven agent-based modeling framework applied to forecasting individual and aggregate residential rooftop solar adoption in San Diego county. Our first step is to learn a model of individual agent behavior from combined data of individual adoption characteristics and property assessment. We then construct an agent-based simulation with the learned model embedded in artificial agents, and proceed to validate it using a holdout sequence of collective adoption decisions. We demonstrate that the resulting agent-based model successfully forecasts solar adoption trends andmore » provides a meaningful quantification of uncertainty about its predictions. We utilize our model to optimize two classes of policies aimed at spurring solar adoption: one that subsidizes the cost of adoption, and another that gives away free systems to low-income house- holds. We find that the optimal policies derived for the latter class are significantly more efficacious, whereas the policies similar to the current California Solar Initiative incentive scheme appear to have a limited impact on overall adoption trends.« less

Battery charging and discharging research based on the interactive technology of smart grid and electric vehicle

NASA Astrophysics Data System (ADS)

Zhang, Mingyang

2018-06-01

To further study the bidirectional flow problem of V2G (Vehicle to Grid) charge and discharge motor, the mathematical model of AC/DC converter and bi-directional DC/DC converter was established. Then, lithium battery was chosen as the battery of electric vehicle and its mathematical model was established. In order to improve the service life of lithium battery, bidirectional DC/DC converter adopted constant current and constant voltage control strategy. In the initial stage of charging, constant current charging was adopted with current single closed loop control. After reaching a certain value, voltage was switched to constant voltage charging controlled by voltage and current. Subsequently, the V2G system simulation model was built in MATLAB/Simulink. The simulation results verified the correctness of the control strategy and showed that when charging, constant current and constant voltage charging was achieved, the grid side voltage and current were in the same phase, and the power factor was about 1. When discharging, the constant current discharge was applied, and the grid voltage and current phase difference was r. To sum up, the simulation results are correct and helpful.

2011-01-01

Objective: The current study investigated the relationship between different types of academic motives—specifically, intrinsic motivation, introjected regulation, and external regulation—and high school students' current and lifetime alcohol consumption. Method: One thousand sixty-seven high school students completed measures of academic motivation, other school-related factors, and lifetime and current alcohol consumption. Results: Using structural equation modeling, different types of motivation and school-related factors were differentially related to student drinking. Specifically, intrinsic motivation was negatively related to lifetime and current alcohol consumption. External regulation, on the other hand, was positively associated with current drinking. Grade point average was the only school-related factor related to student alcohol use. Conclusions: These findings suggest that motivation is an important construct to consider in predicting students’ alcohol use, even when other more commonly studied educational variables are considered. In addition, it supports the adoption of a motivation framework that considers different types of motivation in understanding the relationship between academic motivation and alcohol use. Suggestions for incorporating the self-determination model of motivation into studies of alcohol and substance use, as well as potential impacts on intervention efforts, are discussed. In particular, it may be important to foster only certain types of motivation, rather than all types of academically-focused motives, in efforts to deter alcohol use. PMID:22051210

E-detailing means using digital technology: internet, video conferencing and interactive voice response. There are two types of e-detailing: interactive (virtual) and video. Currently, little is known about what factors influence physicians' adoption of e-detailing. The objectives of this study were to test a model of physicians' adoption of e-detailing and to describe physicians using e-detailing. A mail survey was sent to a random sample of 2000 physicians practicing in Iowa. Binomial logistic regression was used to test the model of influences on physician adoption of e-detailing. On the basis of Rogers' model of adoption, the independent variables included relative advantage, compatibility, complexity, peer influence, attitudes, years in practice, presence of restrictive access to traditional detailing, type of specialty, academic affiliation, type of practice setting and control variables. A total of 671 responses were received giving a response rate of 34.7%. A total of 141 physicians (21.0%) reported using of e-detailing. The overall adoption model for using either type of e-detailing was found to be significant. Relative advantage, peer influence, attitudes, type of specialty, presence of restrictive access and years of practice had significant influences on physician adoption of e-detailing. The model of adoption of innovation is useful to explain physicians' adoption of e-detailing.

Challenges of implementing fibromyalgia treatment guidelines in current clinical practice.

PubMed

Arnold, Lesley M; Clauw, Daniel J

2017-09-01

The current diagnostic and treatment pathway for patients with fibromyalgia (FM) is lengthy, complex, and characterized by multiple physician visits with an average 2-year wait until diagnosis. It is clear that effective identification and appropriate treatment of FM remain a challenge in current clinical practice. Ideally, FM management involves a multidisciplinary approach with the preferable patient pathway originating in primary care but supported by a range of health care providers, including referral to specialist care when necessary. After the publication of individual clinical studies, high-quality reviews, and meta-analyses, recently published FM treatment guidelines have transitioned from an expert consensus to an evidence-based approach. Evidence-based guidelines provide a framework for ensuring early diagnosis and timely adoption of appropriate treatment. However, for successful outcomes, FM treatments must adopt a more holistic approach, which addresses more than just pain. Impact on the associated symptoms of fatigue and cognitive problems, sleep and mood disturbances, and lowered functional status are also important in judging the success of FM therapy. Recently published guidelines recommend the adoption of a symptom-based approach to guide pharmacologic treatment. Emerging treatment options for FM may be best differentiated on the basis of their effect on comorbid symptoms that are often associated with pain (e.g. sleep disturbance, mood, fatigue). The current review discusses the most recently published Canadian guidelines and the implications of the recent European League Against Rheumatism (EULAR) recommendations, with a focus on the challenges of implementing these guidelines in current clinical practice.

2012-02-01

The current qualitative study of 35 pre-adoptive gay male couples (70 men) examined gay men's motivations to parent and their reasons for pursuing parenthood at the current time. Similar to heterosexual couples, gay men described a range of psychologically-oriented reasons as shaping their decision to become parents. Some of these (e.g., desire to teach a child tolerance) may have been uniquely shaped by their sexual minority status, and others (e.g., desire to give a child a good home) in part reflect their adoptive status. Men named age, finances, and relationship factors, as well as unique contextual factors such as the need to find and move to gay-friendly neighborhoods, as influencing their readiness to pursue parenthood at the current time. Gay men's motivations to parent echo normative life course decision-making processes, but also reflect concerns that are uniquely informed by their sexual minority status.

Approximately 30 000 children are adopted across national borders each year. A review of the literature on the cultural belonging of these internationally adopted children shows substantial differences between the literature from English-speaking countries and that from France and Europe in general. The objective of this study is to start from the discourse of French adoptive parents to explore their representations of their child's cultural belonging and their positions (their thoughts and representations) concerning connections with the child's country of birth and its culture. The study includes 51 French parents who adopted one or more children internationally. Each parent participated in a semi-structured interview, focused on the adoption procedure and their current associations with the child's birth country. The interviews were analyzed according to a qualitative phenomenological method, Interpretative Phenomenological Analysis. The principal themes that emerged from our analysis of the interviews made it possible to classify the parents into three different groups. The first group maintained no association with the child's country of birth and refused any multiplicity of cultural identities. The second group actively maintained regular associations with the child's country of birth and culture and affirmed that their family was multicultural. Finally, the third group adapted their associations with the child's birth country and its culture according to the child's questions and interests. Exploring parental representations of the adopted child enables professionals involved in adoption to provide better support to these families and to do preventive work at the level of family interactions.

Objective The purpose of this study is to reassess the projected rate of Electronic Health Record (EHR) diffusion and examine how the federal government's efforts to promote the use of EHR technology have influenced physicians' willingness to adopt such systems. The study recreates and extends the analyses conducted by Ford et al. 1 The two periods examined come before and after the U.S. Federal Government's concerted activity to promote EHR adoption. Design Meta-analysis and bass modeling are used to compare EHR diffusion rates for two distinct periods of government activity. Very low levels of government activity to promote EHR diffusion marked the first period, before 2004. In 2004, the President of the United States called for a “Universal EHR Adoption” by 2014 (10 yrs), creating the major wave of activity and increased awareness of how EHRs will impact physicians' practices. Measurement EHR adoption parameters—external and internal coefficients of influence—are estimated using bass diffusion models and future adoption rates are projected. Results Comparing the EHR adoption rates before and after 2004 (2001–2004 and 2001–2007 respectively) indicate the physicians' resistance to adoption has increased during the second period. Based on current levels of adoption, less than half the physicians working in small practices will have implemented an EHR by 2014 (47.3%). Conclusions The external forces driving EHR diffusion have grown in importance since 2004 relative to physicians' internal motivation to adopt such systems. Several national forces are likely contributing to the slowing pace of EHR diffusion. PMID:19261931

The nonstandard cooling of a neutron star with the central pion core is explored. By adopting the latest results from the pion condensation theory, neutrino emissivity is calulated for both pure charged pions and a mixture of charged and neutral pions, and the equations of state are constructed for the pion condensate. The effect of superfluidity on cooling is investigated, adopting methods more realistic than in previous studies. Our theoretical models are compared with the currently updated observational data, and possible implications are explored.

Lesbian, Gay, and Heterosexual Adoptive Parents' Experiences in Preschool Environments

Little research has examined the school experiences of lesbian/gay (LG) parent families or adoptive parent families. The current exploratory study examined the experiences of 79 lesbian, 75 gay male, and 112 heterosexual adoptive parents of preschool-age children with respect to their (a) level of disclosure regarding their LG parent and adoptive family status at their children's schools; (b) perceived challenges in navigating the preschool environment and advocating on behalf of their children and families; and (c) recommendations to teachers and schools about how to create affirming school environments with respect to family structure, adoption, and race/ethnicity. Findings revealed that the majority of parents were open about their LG and adoptive family status, and had not encountered challenges related to family diversity. Those parents who did experience challenges tended to describe implicit forms of marginalization, such as insensitive language and school assignments. Recommendations for teachers included discussing and reading books about diverse families, tailoring assignments to meet the needs of diverse families, and offering school community-building activities and events to help bridge differences across families.

Mindfulness training, which teaches individuals to bring awareness and acceptance to the present moment, has been effective in improving the well-being of health care workers. Limited research examines the adoption of mindfulness practices using health behavior theories. The current study sought to conceptualize hospital health care workers' experiences in adopting mindfulness practices using the Health Belief Model (HBM), a theoretical framework used by health promotion practitioners to design and implement health behavior change interventions. Hospital health care workers in Colorado participated in an 8-week Mindfulness-Based Stress Reduction (MBSR) course. Participants ( n = 19) answered open-ended questions about their experiences adopting mindfulness practices. A theory-driven thematic analysis approach was used to analyze data with key constructs of the HBM acting as the framework for the analysis. Results showed that HBM constructs, including internal cues to action, perceived benefits and barriers, and self-efficacy, helped portray the participants' experiences and challenges in adopting and adhering to the mindfulness practices taught in the MBSR course.

Healthy public policy is an important tool for creating environments that support human health and wellbeing. At the local level, municipal policies, such as zoning bylaws, provide an opportunity for governments to regulate building location and the type of services offered. Across North America, there has been a recent proliferation of municipal bylaws banning fast food drive-through services. Research on the utilization of this policy strategy, including bylaw adopters and adopter characteristics, is limited within the Canadian context. The aim of this study was to identify and characterize Canadian municipalities based on level of policy innovation and nature of their adopted bylaw banning fast food drive-through services. A multiple case history methodology was utilized to identify and analyse eligible municipal bylaws, and included development of a chronological timeline and map of adopter municipalities within Canada. Grey literature and policy databases were searched for potential adopters of municipal fast food drive-through service bylaws. Adopters were confirmed through evidence of current municipal bylaws. Geographic diffusion and diffusion of innovations theories provided a contextual framework for analysis of bylaw documents. Analysis included assignment of adopter-types, extent and purpose of bans, and policy learning activities of each adopter municipality. From 2002 to 2016, 27 municipalities were identified as adopters: six innovators and twenty-one early adopters. Mapping revealed parallel geographic diffusion patterns in western and eastern Canada. Twenty-two municipalities adopted a partial ban and five adopted a full ban. Rationales for the drive-through bans included health promotion, environmental concerns from idling, community character and aesthetics, traffic concerns, and walkability. Policy learning, including research and consultation with other municipalities, was performed by nine early adopters. This study detailed the adoption of fast food drive-through bylaws across Canada. Understanding the adopter-type characteristics of municipalities and the nature of their bylaws can assist other jurisdictions in similar policy efforts. While the implications for research and practice are evolving and dynamic, fast food drive-through service bans may play a role in promoting healthier food environments. Further research is required to determine the viability of this strategy for health promotion and chronic disease prevention.

Despite the advantages of electronic health record (EHR) systems, the adoption of these systems has been slow among community-based physicians. Current studies have examined organizational and personal barriers to adoption; however, the influence of market characteristics has not been studied. The purpose of this study was to measure the effects of market characteristics on EHR adoption by physicians. Generalized hierarchal linear modeling was used to analyze EHR survey data from Florida which were combined with data from the Area Resource File and the Florida Office of Insurance Regulation. The main outcome variable was self-reported use of EHR by physicians. A total of 2,926 physicians from practice sizes of 20 or less were included in the sample. Twenty-one percent (n = 613) indicated that they personally and routinely use an EHR system in their practice. Physicians located in counties with higher physician concentration were found to be more likely to adopt EHRs. For every one-unit increase in nonfederal physicians per 10,000 in the county, there was a 2.0% increase in likelihood of EHR adoption by physicians (odds ratio = 1.02, confidence interval = 1.00-1.03). Health maintenance organization penetration rate and poverty level were not found to be significantly related to EHR adoption. However, practice size, years in practice, Medicare payer mix, and measures of technology readiness were found to independently influence physician adoption. Market factors play an important role in the diffusion of EHRs in small medical practices. Policy makers interested in furthering the adoption of EHRs must consider strategies that would enhance the confidence of users as well as provide financial support in areas with the highest concentration of small medical practices and Medicare beneficiaries. Health care leaders should be cognizant of the market forces that enable or constrain the adoption of EHR among their practices and those of their competitors.

Dragoni, Nicola; Mazzara, Manuel

While current studies on Web services composition are mostly focused - from the technical viewpoint - on standards and protocols, this work investigates the adoption of formal methods for dependable composition. The Web Services Business Process Execution Language (WS-BPEL) - an OASIS standard widely adopted both in academic and industrial environments - is considered as a touchstone for concrete composition languages and an analysis of its ambiguous Recovery Framework specification is offered. In order to show the use of formal methods, a precise and unambiguous description of its (simplified) mechanisms is provided by means of a conservative extension of the π-calculus. This has to be intended as a well known case study providing methodological arguments for the adoption of formal methods in software specification. The aspect of verification is not the main topic of the paper but some hints are given.

2009-01-01

This research was conducted at a Substance Abuse Forum designed to address local community needs by focusing on Evidence-Based Practices (EBPs) in addiction treatment. The purpose of the study was to assess substance abuse treatment professionals’ readiness to adopt EBPs, experience with EBPs, and attitudes toward EBPs, as well as agency support for EBPs. A total of 119 addiction treatment providers completed pre-test measures, and 82% completed a post-test. Eighty-three percent of participants reported using some EBPs in the past year, and 75% reported currently using EBPs. Participants who were currently licensed or certified in addictions had less negative attitudes toward EBPs than those without credentials. While respondents reported agency support for EBPs, most expressed interest in further training. This study underscores the movement toward EBPs in addiction treatment and the need for effective dissemination and training in this area. PMID:18724657

Foster-to-adopt families can be viewed as systems that are influenced by many other systems (e.g., the legal system, the social service agency, and the birth family). The current qualitative study of 84 foster-to-adopt parents (members of 42 lesbian, gay, and heterosexual couples) examined the types of challenges that parents faced as they navigated multiple systems during the initial post-placement period. Some participants described the legal insecurity associated with their role as foster-to-adopt parents as impacting their personal well-being and their attachment to their children. Lack of support services and disorganization within social service agencies, as well as strained relationships with birth parents, were also identified as stressors for foster-to-adopt parents. Importantly, lesbian and gay participants faced additional concerns regarding the security of their placement, due to the possibility for discrimination within the various systems involved with the foster-to-adopt process. Participants as a whole also identified positive aspects of their experiences within various systems; for example, they appreciated child care subsidies, state-provided health insurance, and supportive social workers. Our findings provide insights into foster-to-adopt parents’ experiences during the initial post-placement period, and have implications for adoption services aimed to improve placement stability and enhance family functioning in foster-to-adopt families.

Age at adoption from institutional care as a window into the lasting effects of early experiences

PubMed Central

Julian, Megan M.

2013-01-01

One of the major questions of human development is how early experience impacts the course of development years later. Children adopted from institutional care experience varying levels of deprivation in their early life followed by qualitatively better care in an adoptive home, providing a unique opportunity to study the lasting effects of early deprivation and its timing. The effects of age at adoption from institutional care are discussed for multiple domains of social and behavioral development within the context of several prominent developmental hypotheses about the effects of early deprivation (cumulative effects, experience-expectant developmental programming, and experience-adaptive developmental programming). Age at adoption effects are detected in a majority of studies, particularly when children experienced global deprivation and were assessed in adolescence. For most outcomes, institutionalization beyond a certain age is associated with a step-like increase in risk for lasting social and behavioral problems, with the step occurring at an earlier age for children who experienced more severe levels of deprivation. Findings are discussed in terms of their concordance and discordance with our current hypotheses, and speculative explanations for the findings are offered. PMID:23576122

Adopting and implementing nutrition guidelines in recreational facilities: Public and private sector roles. A multiple case study

PubMed Central

2012-01-01

Background Recreational facilities are an important community resource for health promotion because they provide access to affordable physical activities. However, despite their health mandate, many have unhealthy food environments that may paradoxically increase the risk of childhood obesity. The Alberta Nutrition Guidelines for Children and Youth (ANGCY) are government-initiated, voluntary guidelines intended to facilitate children’s access to healthy food and beverage choices in schools, childcare and recreational facilities, however few recreational facilities are using them. Methods We used mixed methods within an exploratory multiple case study to examine factors that influenced adoption and implementation of the ANGCY and the nature of the food environment within three cases: an adopter, a semi-adopter and a non-adopter of the ANGCY. Diffusion of Innovations theory provided the theoretical platform for the study. Qualitative data were generated through interviews, observations, and document reviews, and were analysed using directed content analysis. Set theoretic logic was used to identify factors that differentiated adopters from the non-adopter. Quantitative sales data were also collected, and the quality of the food environment was scored using four complementary tools. Results The keys to adoption and implementation of nutrition guidelines in recreational facilities related to the managers’ nutrition-related knowledge, beliefs and perceptions, as these shaped his decisions and actions. The manager, however, could not accomplish adoption and implementation alone. Intersectoral linkages with schools and formal, health promoting partnerships with industry were also important for adoption and implementation to occur. The food environment in facilities that had adopted the ANGCY did not appear to be superior to the food environment in facilities that had not adopted the ANGCY. Conclusions ANGCY uptake may continue to falter under the current voluntary approach, as the environmental supports for voluntary action are poor. Where ANGCY uptake does occur, changes to the food environment may be relatively minor. Stronger government measures may be needed to require recreational facilities to improve their food environments and to limit availability of unhealthy foods. PMID:22632384

2009-01-01

The purpose of this study was to examine the adoption of health information technology by children's hospitals and to document barriers and priorities as they relate to health information technology adoption. Primary data of interest were obtained through the use of a survey instrument distributed to the chief information officers of 199 children's hospitals in the United States. Data were collected on current and future use of a variety of clinical health information technology and telemedicine applications, organizational priorities, barriers to use of health information technology, and hospital and chief information officer characteristics. Among the 109 responding hospitals (55%), common clinical applications included clinical scheduling (86.2%), transcription (85.3%), and pharmacy (81.9%) and laboratory (80.7%) information. Electronic health records (48.6%), computerized order entry (40.4%), and clinical decision support systems (35.8%) were less common. The most common barriers to health information technology adoption were vendors' inability to deliver products or services to satisfaction (85.4%), lack of staffing resources (82.3%), and difficulty in achieving end-user acceptance (80.2%). The most frequent priority for hospitals was to implement technology to reduce medical errors or to promote safety (72.5%). This first national look at health information technology use by children's hospitals demonstrates the progress in health information technology adoption, current barriers, and priorities for these institutions. In addition, the findings can serve as important benchmarks for future study in this area.

2012-10-01

This study examined the perceived barriers to adopting an Asian-language quitline service among agencies that fund current state quitline services across the U.S. A self-administered survey on organizational readiness was sent to the funding agencies of 47 states plus Washington D.C. that currently fund state quitlines in English and Spanish, but not in Asian languages (response rate = 58%). The 2010 Census and the 2009 North American Quitline Consortium Survey were used to obtain the proportion of Asians among the state population and state quitline funding level, respectively. The most frequently cited reasons for not adopting an Asian quitline are: the Asian population in the state would be too small (71.4%), costs of service would be too high (57.1%), and the belief that using third-party translation for counseling is sufficient (39.3%). However, neither the actual proportion of Asians among the state population (range = 0.7% to 7.3%), nor the quitline funding level (range = $0.17 to $20.8 per capita) predicts the reported reasons. The results indicate that quitline funding agencies need more education on the necessity and the feasibility of an Asian-language quitline. Three states are currently participating in a multi-state Asian-language quitline in which each state promotes the service to its residents and one state (CA) provides the services for all the states. This centralized multi-state Asian-language quitline operation, which helps reduce practical barriers in adoption and disparity in access to service, could be extended.

Predictors of school engagement among same-sex and heterosexual adoptive parents of Kindergarteners.

Goldberg, Abbie E; Smith, JuliAnna Z

2014-10-01

Little research has explored parental engagement in schools in the context of adoptive parent families or same-sex parent families. The current cross-sectional study explored predictors of parents' self-reported school involvement, relationships with teachers, and school satisfaction, in a sample of 103 female same-sex, male same-sex, and heterosexual adoptive parent couples (196 parents) of kindergarten-age children. Parents who reported more contact by teachers about positive or neutral topics (e.g., their child's good grades) reported more involvement and greater satisfaction with schools, regardless of family type. Parents who reported more contact by teachers about negative topics (e.g., their child's behavior problems) reported better relationships with teachers but lower school satisfaction, regardless of family type. Regarding the broader school context, across all family types, parents who felt more accepted by other parents reported more involvement and better parent-teacher relationships; socializing with other parents was related to greater involvement. Regarding the adoption-specific variables, parents who perceived their children's schools as more culturally sensitive were more involved and satisfied with the school, regardless of family type. Perceived cultural sensitivity mattered more for heterosexual adoptive parents' relationships with their teachers than it did for same-sex adoptive parents. Finally, heterosexual adoptive parents who perceived high levels of adoption stigma in their children's schools were less involved than those who perceived low levels of stigma, whereas same-sex adoptive parents who perceived high levels of stigma were more involved than those who perceived low levels of stigma. Our findings have implications for school professionals, such as school psychologists, who work with diverse families. Copyright © 2014 Society for the Study of School Psychology.

To assess the current state of electronic health record (EHR) use by ophthalmologists, including adoption rate, user satisfaction, functionality, benefits, barriers, and knowledge of meaningful use criteria. Population-based, cross-sectional study. A total of 492 members of the American Academy of Ophthalmology (AAO). A random sample of 1500 AAO members were selected on the basis of their practice location and solicited to participate in a study of EHR use, practice management, and image management system use. Participants completed the survey via the Internet, phone, or fax. The survey included questions about the adoption of EHRs, available functionality, benefits, barriers, satisfaction, and understanding of meaningful use criteria and health information technology concepts. Current adoption rate of EHRs, user satisfaction, benefits and barriers, and availability of EHR functionality. Overall, 32% of the practices surveyed had already implemented an EHR, 15% had implemented an EHR for some of their physicians or were in the process of implementation, and another 31% had plans to do so within 2 years. Among those with an EHR in their practice, 49% were satisfied or extremely satisfied with their system, 42% reported increased or stable overall productivity, 19% reported decreased or stable overall costs, and 55% would recommend an EHR to a fellow ophthalmologist. For those with an electronic image management system, only 15% had all devices integrated, 33% had images directly uploaded into their system, and 12% had electronic association of patient demographics with the image. The adoption of EHRs by ophthalmology practices more than doubled from 2007 to 2011. The satisfaction of ophthalmologists with their EHR and their perception of beneficial effects on productivity and costs were all lower in 2011 than in 2007. Knowledge about meaningful use is high, but the percentage of physicians actually receiving incentive payments is relatively low. Given the importance of imaging in ophthalmology, the shortcomings in current image management systems need to be addressed.

2018-01-01

Mobile chronic disease management systems (MCDMS) have become increasingly important in recent years, but in China, challenges remain for their adoption. Existing empirical studies have not completely explored the adoption behavior of potential MCDMS users. This article presents a study in which we investigated factors that influence chronically ill patients in China and their families to adopt or decline to use MCDMS. We applied a research model based on the technology acceptance model (TAM) as well as four contextual constructs (perceived disease threat, perceived risk, initial trust, and technology anxiety) to a survey of 279 potential MCDMS service participants in China. Our key findings include: (1) as consistent with current research, both perceived usefulness and perceived ease of use have positive impact on potential users' MCDMS adoption intention; (2) both perceived disease threat and initial trust have positive impact on MCDMS adoption intention; (3) the impact of perceived risk is negative, and technology anxiety has negative impact on perceived ease of use of MCDMS; (4) young people place more importance on their perceptions of usefulness, ease of operation, and disease threat than middle-aged and older users; (5) family members are more influenced by their perception of ease of use and disease threat than chronically ill patients, while chronically ill patients place more importance on perceived usefulness than family members. This article concludes by discussing the implications of our study for research and practice, as well as limitations and future research directions.

Anthelmintic resistance is emerging in dairy cattle and this can result in a lack of effective control and production losses. Therefore, sustainable control strategies, such as targeted treatments (TT) and targeted selected treatments (TST), should be adopted by the industry. TT and TST approaches require the use of diagnostic methods to take informed treatment decisions. To understand the factors affecting the farmers' intention to adopt diagnostic methods before implementing anthelmintic drugs ('adoption intention'), a cross-sectional survey was carried out in dairy farms in Belgium (Flanders). A framework was constructed to predict adoption intentions based on two fundamental theories in the field of behavioural psychology and health psychology: the Theory of Planned Behaviour and the Health Belief Model. In the tested model, adoption intentions were predicted based on attitudes towards anthelminthics, attitudes towards diagnostic methods, subjective norms, behavioural control and perceived risk. Structural equation modelling was used for analyses. The model fitted the data well and explained 46% of the variance in adoption intention of diagnostics. The factors 'attitude towards diagnostic methods' and 'subjective norm'; i.e. the influence of significant others, had the strongest, positive influence on adoption intention of diagnostic methods. 'Perceived behavioural control' had a weak, positive effect on intention. Further, 'attitude towards the use of anthelmintic drugs' had a negative effect on adoption intention of the diagnostic methods. This implicates an effect of current behaviour on future adoption, which should be considered in future research. Factors measuring risk perception of anthelmintic resistance; perceived severity and perceived susceptibility, had no effect on the adoption intention of diagnostic methods. The threat of anthelmintic resistance is perceived to be low for dairy herds. The study further did not find any differences in the effects of the predictors for young stock and adult dairy cows. The results of this study can be used to develop communication strategies to advertise sustainable nematode control on dairy farms. Copyright © 2015 Elsevier B.V. All rights reserved.

This study examines the effect of air quality and administrative policies on use of urban trails in Indianapolis, IN. Attention is focused on two policy variables: (1) issuance of air pollution advisories and (2) the adoption of Daylight Savings Time. Results suggest that while trail use varies with air quality, current public advisories regarding air pollution may be of limited effectiveness in reducing trail users' exposures to hazardous pollutants. In contrast, the adoption of Daylight Savings Time was associated with a statistically significant increase in traffic levels.

Diffusion of laparoscopic cholecystectomy among general surgeons in the United States.

1995-03-01

Introduced in 1989, laparoscopic cholecystectomy has rapidly become the treatment of choice for symptomatic gallstones. This study describes the diffusion of laparoscopic cholecystectomy among general surgeons; assesses the importance of various reasons for surgeons adopting the procedure; and examine the influence of surgeon, practice, and health care market characteristics on the timing of adoption. The data were obtained from a survey of a national sample of surgeons. Most surgeons (81%) adopted laparoscopic cholecystectomy by early 1992. More than three fourths of adopters identified the desire to keep up with the state-of-the-art and improved patient outcomes as very or extremely important reasons for adoption. Results of proportional hazards regression analysis indicate that individual surgeons' adoption behavior generally was consistent with expected utility maximization in an uncertain new technological environment. Of particular interest, fee-for-service payment and more competitive practice settings and markets were associated with earlier adoption. These findings suggest that the "technological imperative" and surgeons' perception of the relative clinical and financial advantages of laparoscopic cholecystectomy were important reasons for the rapid diffusion of laparoscopic cholecystectomy. Policies that accelerate current trends toward payment of physicians based on salary or capitation and promote the growth of multispecialty group practice could slow the diffusion of new physician-based product innovations in health care.

In early 2016, the United States and Canada formally agreed to reduce phosphorus inputs to Lake Erie by 40% to reduce the severity of annual Harmful Algal Blooms (HABs). These blooms have become more severe, with record events occurring in 2011 and 2015, and have compromised public safety, shut down drinking water supplies, and negatively impacted the economy of the western Lake Erie basin. Now, a key question is what management options should be pursued to reach the 40% reduction. This presentation will highlight interdisciplinary research to compare the amount and types of practices needed for this reduction to the current and projected levels of adoption. Multiple models of the Maumee watershed identified management plans and adoption rates needed to reach the reduction targets. For example, one successful scenario estimated necessary adoption rates of 50% for subsurface application of fertilizer on row crops, 58% for cover crops, and 78% for buffer strips. Current adoption is below these levels, but future projections based on farmer surveys shows these levels are possible. This information was then used to guide another round of watershed modeling analysis to evaluate scenarios that represented more realistic scenarios based on potential levels of management adoption. In general, these results show that accelerated adoption of management plans is needed compared to past adoption rates, and that some of these greater adoption levels are possible based on likely adoption rates. Increasing the perceived efficacy of the practices is one method that will support greater voluntary rates of adoption.

Chimeric Antigen Receptor T Cell Therapy in Hematology.

It is well demonstrated that the immune system can control and eliminate cancer cells. Immune-mediated elimination of tumor cells has been discovered and is the basis of both cancer vaccines and cellular therapies including hematopoietic stem cell transplantation. Adoptive T cell transfer has been improved to be more specific and potent and to cause less off-target toxicity. Currently, there are two forms of engineered T cells being tested in clinical trials: T cell receptor (TCR) and chimeric antigen receptor (CAR) modified T cells. On 1 July 2014, the United States Food and Drug Administration granted 'breakthrough therapy' designation to anti-CD19 CAR T cell therapy. Many studies were conducted to evaluate the benefits of this exciting and potent new treatment modality. This review summarizes the history of adoptive immunotherapy, adoptive immunotherapy using CARs, the CAR manufacturing process, preclinical and clinical studies, and the effectiveness and drawbacks of this strategy.

2012-02-01

The current study examines the interplay between parental overreactivity and children's genetic backgrounds as inferred from birth parent characteristics on the development of negative emotionality during infancy, and in turn, to individual differences in externalizing problems in toddlerhood. The sample included 361 families linked through adoption (birth parents and adoptive families). Data were collected when the children were 9, 18, and 27 months old. Results indicated links between individual levels and changes in negative emotionality during infancy and toddlerhood to externalizing problems early in the third year of life. Findings also revealed an interaction between birth mother negative affect and adoptive mother overreactive parenting on children's negative emotionality. This Genotype × Environment interaction predicted externalizing problems indirectly through its association with negative emotionality and revealed stronger effects of genetic risk for children with less overreactive parenting from their mothers. Limitations of this study and directions for future research are discussed.

It has become a trend that worldwide enterprises and organizations apply new technologies to improve their operations; besides, it has higher cost and less flexibility to construct and manage traditional servers, therefore the current mainstream is to use server virtualization technology. However, from these new technology organizations will not necessarily get the expected benefits because each one has its own level of organizational complexity and abilities to accept changes. The researcher investigated key factors affecting the adoption of virtualization technology through two phases. In phase I, the researcher reviewed literature and then applied the dimensions of "Information Systems Success Model" (ISSM) to generalize the factors affecting the adoption of virtualization technology to be the preliminary theoretical framework and develop a questionnaire; in phase II, a three-round Delphi Method was used to integrate the opinions of experts from related fields which were then gradually converged in order to obtain a stable and objective questionnaire of key factors so that these results were expected to provide references for organizations' adoption of server virtualization technology and future studies.

High School Teachers’ Openness to Adopting New Practices: The Role of Personal Resources and Organizational Climate

2016-01-01

Although evidence-based practices for students’ social, emotional, and behavioral health are readily available, their adoption and quality implementation in schools are of increasing concern. Teachers are vital to implementation; yet, there is limited research on teachers’ openness to adopting new practices, which may be essential to successful program adoption and implementation. The current study explored how perceptions of principal support, teacher affiliation, teacher efficacy, and burnout relate to teachers’ openness to new practices. Data came from 2,133 teachers across 51 high schools. Structural equation modeling assessed how organizational climate (i.e., principal support and teacher affiliation) related to teachers’ openness directly and indirectly via teacher resources (i.e., efficacy and burnout). Teachers with more favorable perceptions of both principal support and teacher affiliation reported greater efficacy, and, in turn, more openness; however, burnout was not significantly associated with openness. Post hoc analyses indicated that among teachers with high levels of burnout, only principal support related to greater efficacy, and in turn, higher openness. Implications for promoting teachers’ openness to new program adoption are discussed. PMID:28533823

Agrawal, M; Calantone, R J

1995-01-01

New drug products today are the key to survival in the pharmaceutical industry. However, the new product development process in the pharmaceutical industry also happens to be one of the riskiest and most expensive undertakings because of the huge research and development costs involved. Consequently market forecasting of new pharmaceutical products takes on added importance if the formidable investments are to be recovered. New drug adoption models provide the marketer with a means to assess new product potential. Although several adoption models are available in the marketing literature for assessing potential of common consumer goods, the unique characteristics of the prescription drug market makes it necessary to examine the current state of pharmaceutical innovations. The purpose of this study, therefore, is to: (1) review new drug adoption models in the pharmaceutical literature, (2) evaluate the existing models of new drug adoption using the ten criteria for a good model as prescribed by Zaltman and Wallendorf (1983), and (3) provide an overall assessment and a ¿prescription¿ for better forecasting of new drug products.

Reducing Lake Erie's Harmful Algal Blooms: Projection and Adoption of Management Plans

In early 2016, the United States and Canada formally agreed to reduce phosphorus inputs to Lake Erie by 40% to reduce the severity of annual Harmful Algal Blooms (HABs). These blooms have become more severe, with record events occurring in 2011 and 2015, and have compromised public safety, shut down drinking water supplies, and negatively impacted the economy of the western Lake Erie basin. Now, key questions revolve around the ability to reach the 40% reduction, required management changes, and resources to support these changes. This presentation will highlight interdisciplinary research to compare the amount and types of practices needed for this reduction to the current and projected levels of adoption. Economic resources to support these management changes are also compared with the financial support from the general public to improve Lake Erie water quality. Multiple models of the Maumee watershed identified management plans and adoption rates needed to reach the reduction targets. For example, one successful scenario estimated necessary adoption rates of 50% for subsurface application of fertilizer on row crops, 58% for cover crops, and 78% for buffer strips. Current adoption is below these levels, but future projections based on farmer surveys shows these levels are possible. Public support is necessary to generate the funding to support cost sharing and other programs aimed at increasing adoption of recommended practices. Comparing results from willingness-to-pay surveys of the general public with the estimated need for these management plans shows a gap in resources to support these levels of adoption. In general, these results show that accelerated adoption of management plans is needed compared to past adoption rates, but that these rates are possible based on likely adoption rates. Projected support from the general public indicates it will be challenging to fund these rates of adoption, especially during climate changes that may require even greater adoption. To partially address this challenge, accelerated rates of adoption may be achieved through voluntary means by increasing the perceived efficacy of the practices.

Why sub-Saharan Africa lags in electronic health record adoption and possible strategies to increase its adoption in this region

Poor health information system has been identified as a major challenge in the health-care system in many developing countries including sub-Saharan African countries. Electronic health record (EHR) has been shown as an important tool to improve access to patient information with attendance improved quality of care. However, EHR has not been widely implemented/adopted in sub-Saharan Africa. This study sought to identify factors that affect the adoption of an EHR in sub-Saharan Africa and strategies to improve its adoption in this region. A comprehensive literature search was conducted on three electronic databases: PubMed, Medline, and Google Scholar. Articles of interest were those published in English that contained information on factors that limit the adoption of an EHR as well as strategies that improve its adoption in sub-Saharan African countries. The available evidence indicated that there were many factors that hindered the widespread adoption of an EHR in sub-Saharan Africa. These were high costs of procurement and maintenance of the EHR system, lack of financial incentives and priorities, poor electricity supply and internet connectivity, and primary user’s limited computer skills. However, strategies such as implementation planning, financial supports, appropriate EHR system selection, training of primary users, and the adoption of the phased implementation process have been identified to facilitate the use of an EHR. Wide adoption of an EHR in sub-Saharan Africa region requires a lot more effort than what is assumed because of the current poor level of technological development, lack of required computer skills, and limited resources.

Shared environmental influences on personality: A combined twin and adoption approach

Matteson, Lindsay K.; McGue, Matt; Iacono, William G.

2013-01-01

In the past, shared environmental influences on personality traits have been found to be negligible in behavior genetic studies (e.g., Bouchard & McGue, 2003). However, most studies have been based on biometrical modeling of twins only. Failure to meet key assumptions of the classical twin design could lead to biased estimates of shared environmental effects. Alternative approaches to the etiology of personality are needed. In the current study we estimated the impact of shared environmental factors on adolescent personality by simultaneously modeling both twin and adoption data. We found evidence for significant shared environmental influences on Multidimensional Personality Questionnaire (MPQ) Absorption (15% variance explained), Alienation (10%), Harm Avoidance (14%), and Traditionalism (26%) scales. Additionally, we found that in most cases biometrical models constraining parameter estimates to be equal across study type (twins versus adoptees) fit no worse than models allowing these parameters to vary; this suggests that results converge across study design despite the potential (sometimes opposite) biases of twin and adoption studies. Thus, we can be more confident that our findings represent the true contribution of shared environmental variance to personality development. PMID:24065564

2008-01-01

The article provides a review and considers how the diffusion of innovations Research paradigm has changed, and offers suggestions for the further development of this theory of social change. Main emphases of diffusion Research studies are compared over time, with special attention to applications of diffusion theory-based concepts as types of dissemination science. A considerable degree of paradigmatic evolution is observed. The classical diffusion model focused on adopter innovativeness, individuals as the locus of decision, communication channels, and adoption as the primary outcome measures in post hoc observational study designs. The diffusion systems in question were centralized, with fidelity of implementation often assumed. Current dissemination Research and practice is better characterized by tests of interventions that operationalize one or more diffusion theory-based concepts and concepts from other change approaches, involve complex organizations as the units of adoption, and focus on implementation issues. Foment characterizes dissemination and implementation Research, Reflecting both its interdisciplinary Roots and the imperative of spreading evidence-based innovations as a basis for a new paradigm of translational studies of dissemination science.

Melanoma is the most aggressive skin cancer and its incidence is gradually increasing worldwide. Patients with metastatic melanoma have a very poor prognosis (estimated 5-year survival rate of <16%). In the last few years, several drugs have been approved for malignant melanoma, such as tyrosine kinase inhibitors and immune checkpoint blockades. Although new therapeutic agents have improved progression-free and overall survival, their use is limited by drug resistance and drug-related toxicity. At the same time, adoptive cell therapy of metastatic melanoma with tumor-infiltrating lymphocytes has shown promising results in preclinical and clinical studies. In this review, we summarize the currently available drugs for treatment of malignant melanoma. In addition, we suggest cytokine-induced killer (CIK) cells as another candidate approach for adoptive cell therapy of melanoma. Our preclinical study and several previous studies have shown that CIK cells have potent anti-tumor activity against melanomas in vitro and in an in vivo human tumor xenograft model without any toxicity.

Atypical EEG power correlates with indiscriminately friendly behavior in internationally adopted children.

Tarullo, Amanda R; Garvin, Melissa C; Gunnar, Megan R

2011-03-01

While effects of institutional care on behavioral development have been studied extensively, effects on neural systems underlying these socioemotional and attention deficits are only beginning to be examined. The current study assessed electroencephalogram (EEG) power in 18-month-old internationally adopted, postinstitutionalized children (n = 37) and comparison groups of nonadopted children (n = 47) and children internationally adopted from foster care (n = 39). For their age, postinstitutionalized children had an atypical EEG power distribution, with relative power concentrated in lower frequency bands compared with nonadopted children. Both internationally adopted groups had lower absolute alpha power than nonadopted children. EEG power was not related to growth at adoption or to global cognitive ability. Atypical EEG power distribution at 18 months predicted indiscriminate friendliness and poorer inhibitory control at 36 months. Both postinstitutionalized and foster care children were more likely than nonadopted children to exhibit indiscriminate friendliness. Results are consistent with a cortical hypoactivation model of the effects of early deprivation on neural development and provide initial evidence associating this atypical EEG pattern with indiscriminate friendliness. Outcomes observed in the foster care children raise questions about the specificity of institutional rearing as a risk factor and emphasize the need for broader consideration of the effects of early deprivation and disruptions in care.

Has molecular imaging delivered to drug development?

NASA Astrophysics Data System (ADS)

Murphy, Philip S.; Patel, Neel; McCarthy, Timothy J.

2017-10-01

Pharmaceutical research and development requires a systematic interrogation of a candidate molecule through clinical studies. To ensure resources are spent on only the most promising molecules, early clinical studies must understand fundamental attributes of the drug candidate, including exposure at the target site, target binding and pharmacological response in disease. Molecular imaging has the potential to quantitatively characterize these properties in small, efficient clinical studies. Specific benefits of molecular imaging in this setting (compared to blood and tissue sampling) include non-invasiveness and the ability to survey the whole body temporally. These methods have been adopted primarily for neuroscience drug development, catalysed by the inability to access the brain compartment by other means. If we believe molecular imaging is a technology platform able to underpin clinical drug development, why is it not adopted further to enable earlier decisions? This article considers current drug development needs, progress towards integration of molecular imaging into studies, current impediments and proposed models to broaden use and increase impact. This article is part of the themed issue 'Challenges for chemistry in molecular imaging'.

Augmentation of anti-tumor immunity by adoptive T-cell transfer after allogeneic hematopoietic stem cell transplantation

PubMed Central

Bleakley, Marie; Turtle, Cameron J; Riddell, Stanley R

2012-01-01

Allogeneic hematopoietic stem cell transplantation (HCT) is currently the standard of care for most patients with high-risk acute leukemias and some other hematologic malignancies. Although HCT can be curative, many patients who undergo allogeneic HCT will later relapse. There is, therefore, a critical need for the development of novel post-HCT therapies for patients who are at high risk for disease recurrence following HCT. One potentially efficacious approach is adoptive T-cell immunotherapy, which is currently undergoing a renaissance that has been inspired by scientific insight into the key issues that impeded its previous clinical application. Translation of the next generation of adoptive T-cell therapies to the allogeneic HCT setting, using donor T cells of defined specificity and function, presents a unique set of challenges and opportunities.

Malaysia considers the construction industry as one of the main contributors to its Gross Domestic Product (GDP). However, there are some unresolved issues arising from the ongoing and widespread adoption of the conventional method of construction such as the resultant fragmentation of the industry itself; delays in production and delivery time of unnecessary wastages and lack of sustainability practice. Malaysian Government has been continuously encouraging the industry to use, partly or if not wholly, the Industrialized Building System (IBS), which is considered to be an important part of sustainable construction initiative. IBS was introduced to Malaysia as the solution to issues related to dependencies of foreign workers, raising demand for affordable accommodations and improving image, quality and productivity of construction industry. However, the IBS adoption in Malaysia remains low. This paper presents the review of the current issues and barriers of IBS adoption in Malaysian construction industry.

2017-01-01

On July 6 and 7, 2016 the Fourth Artificial Pancreas Workshop: Testing and Adoption of Current and Emerging Technologies was held on the National Institutes of Health (NIH) Campus at the Lister Hill Auditorium. The meeting was sponsored by a group of governmental organizations and NGOs, listed in Appendix A. This was a very timely meeting as the artificial pancreas appears to be growing from academic studies to commercial projects. The first artificial pancreas may be marketed within 12 months and a few may be approved within 24 months. The NIH, the FDA, the JDRF, Helmsley Trust, Diabetes Technology Society, and other agencies, funders, and organizations have been strongly supportive of advancing artificial pancreas technology and usability, and thus the proceedings from this conference should be of exceptional interest to the diabetes technology community.

To refine public health policy amidst a changing landscape of tobacco products in the United States, it is first necessary to describe fully the nature of smokers' alternative product use. Little research addresses smokers' snus use, and most studies are limited by small samples, cross-sectional designs, and crude outcome measurement. This study sample includes 626 adult US smokers who denied intention to quit in the next month and were randomized to receive free snus during a 6-week sampling period, after which no snus was provided. Participants were then followed for one year. Outcome data were collected via phone. Participants (mean age: 48.7years) were predominately female, White non-Hispanic. Eighty-four percent reported trial of snus. Eleven percent reported purchase (i.e., adoption). Current use declined from 47.1% at the end of the sampling period to 6.5% at the end of follow-up. Frequency and quantity of snus use among current users was low. Among snus users, 79.3% said it functioned as an alternative to smoking and 58.4% said it provided a means of coping with smoking restrictions; options not mutually exclusive. In logistic regressions, men were more likely to report trial (odds ratio [OR]=2.33, p<0.01) and adoption (OR=1.84, p<0.05) than women. Baseline expectations about the nature of snus use also predicted snus outcomes (OR=1.28-1.78, p<0.05). Smokers showed willingness to try snus, but product interest waned over time. Snus as currently marketed is unlikely to play a prominent role in US tobacco control efforts. Copyright © 2016 Elsevier Ltd. All rights reserved.

The war at home: affective economics and transnationally adoptive families in the United States.

PubMed

Stryker, Rachael

2011-01-01

The question of how to best conduct post-placement interventions for transnationally adoptive families at risk of dissolution (legal annulment) is an emerging issue in the United States. The current popular trend for adoptive families to pursue biomedical post-placement interventions, despite a lack of proof that such interventions actually work to keep the adoptive family intact, suggests the need for a more phenomenological approach to understanding both adoptive parents’ and transnational adoptees’ post-placement experiences. This study examines the empirical experiences of adoptive families at risk of dissolution in the United States who attempt to define and navigate the path toward family stability after adopting. From the coding of this data set emerge some routes through and by which emotions circulate between adoptive parents and transnational adoptees through the family body and the family social. Particularly, it investigates one post-placement “affective economy” at work in which adoptive parents attempt, through the expression of particular forms of parental love, to align adoptees as subjects of the private, nuclear American family, while adoptees more often attempt to create space for more heterogeneous forms of family, ones that include birth parents and other kin-like relations in their countries of origin. Ultimately, it illuminates some vastly different and sometimes contradictory ways that adoptive parents and adoptees can interpret family through emotional lenses, ones that can prevent a smooth post-placement transition for adoption actors. An understanding of these differences and how they shape, and are shaped by, the post-placement affective economy within families at risk of dissolution may aid in locating indicators for adoption dissolution, and possibly, designing more effective post-placement interventions for families struggling in the aftermath of adoption. It may also help scholars begin to think about the construction and impact of affective economies in the realm of adoption more generally.

Performance of the AOAC use-dilution method with targeted modifications: collaborative study.

Tomasino, Stephen F; Parker, Albert E; Hamilton, Martin A; Hamilton, Gordon C

2012-01-01

The U.S. Environmental Protection Agency (EPA), in collaboration with an industry work group, spearheaded a collaborative study designed to further enhance the AOAC use-dilution method (UDM). Based on feedback from laboratories that routinely conduct the UDM, improvements to the test culture preparation steps were prioritized. A set of modifications, largely based on culturing the test microbes on agar as specified in the AOAC hard surface carrier test method, were evaluated in a five-laboratory trial. The modifications targeted the preparation of the Pseudomonas aeruginosa test culture due to the difficulty in separating the pellicle from the broth in the current UDM. The proposed modifications (i.e., the modified UDM) were compared to the current UDM methodology for P. aeruginosa and Staphylococcus aureus. Salmonella choleraesuis was not included in the study. The goal was to determine if the modifications reduced method variability. Three efficacy response variables were statistically analyzed: the number of positive carriers, the log reduction, and the pass/fail outcome. The scope of the collaborative study was limited to testing one liquid disinfectant (an EPA-registered quaternary ammonium product) at two levels of presumed product efficacies, high and low. Test conditions included use of 400 ppm hard water as the product diluent and a 5% organic soil load (horse serum) added to the inoculum. Unfortunately, the study failed to support the adoption of the major modification (use of an agar-based approach to grow the test cultures) based on an analysis of method's variability. The repeatability and reproducibility standard deviations for the modified method were equal to or greater than those for the current method across the various test variables. However, the authors propose retaining the frozen stock preparation step of the modified method, and based on the statistical equivalency of the control log densities, support its adoption as a procedural change to the current UDM. The current UDM displayed acceptable responsiveness to changes in product efficacy; acceptable repeatability across multiple tests in each laboratory for the control counts and log reductions; and acceptable reproducibility across multiple laboratories for the control log density values and log reductions. Although the data do not support the adoption of all modifications, the UDM collaborative study data are valuable for assessing sources of method variability and a reassessment of the performance standard for the UDM.

Current State of Agile User-Centered Design: A Survey

NASA Astrophysics Data System (ADS)

Hussain, Zahid; Slany, Wolfgang; Holzinger, Andreas

Agile software development methods are quite popular nowadays and are being adopted at an increasing rate in the industry every year. However, these methods are still lacking usability awareness in their development lifecycle, and the integration of usability/User-Centered Design (UCD) into agile methods is not adequately addressed. This paper presents the preliminary results of a recently conducted online survey regarding the current state of the integration of agile methods and usability/UCD. A world wide response of 92 practitioners was received. The results show that the majority of practitioners perceive that the integration of agile methods with usability/UCD has added value to their adopted processes and to their teams; has resulted in the improvement of usability and quality of the product developed; and has increased the satisfaction of the end-users of the product developed. The top most used HCI techniques are low-fidelity prototyping, conceptual designs, observational studies of users, usability expert evaluations, field studies, personas, rapid iterative testing, and laboratory usability testing.

Cloud computing is a new paradigm shift in information technology. Most of the studies in the cloud are business related while the studies in cloud based e-learning are few. The field is still in its infancy and researchers have used several adoption theories to discover the dimensions of this field. The purpose of this paper is to review and integrate the literature to understand the current situation of the cloud based e-learning adoption. A total of 312 articles were extracted from Science direct, emerald, and IEEE. Screening processes were applied to select only the articles that are related to the cloud based e-learning. A total of 231 removed because they are related to business organization. Next, a total of 63 articles were removed because they are technical articles. A total of 18 articles were included in this paper. A frequency analysis was conducted on the paper to identify the most frequent factors, theories, statistical software, respondents, and countries of the studies. The findings showed that usefulness and ease of use are the most frequent factors. TAM is the most prevalent adoption theories in the literature. The mean of the respondents in the reviewed studies is 377 and Malaysia is the most researched countries in terms of cloud based e-learning. Studies of cloud based e-learning are few and more empirical studies are needed.

2018-01-01

An empirical expression describing the electroplastic deformation behavior is suggested based on the Johnson-Cook (JC) model by adding several functions to consider both thermal and athermal electric current effects. Tensile deformation behaviors are carried out for an AZ31 magnesium alloy and an Al-Mg-Si alloy under pulsed electric current at various current densities with a fixed duration of electric current. To describe the flow curves under electric current, a modified JC model is proposed to take the electric current effect into account. Phenomenological descriptions of the adopted parameters in the equation are made. The modified JC model suggested in the present study is capable of describing the tensile deformation behaviors under pulsed electric current reasonably well.

Carrying out a comparative analysis of Andean and Caribbean health systems contributing towards the general panorama of Andean and Caribbean region health care system experience. This study was aimed at carrying out a comparative analysis of health systems in Bolivia, Colombia, Ecuador, Peru, Venezuela, the Dominican Republic and Cuba between 1990 and 2004. Documentary information from secondary sources was used. Reform and changes during the aforementioned period were compared, as well as the systems' current configurations. Described typologies were used for studying the health systems. Different organisational designs were found for the systems: a national health system (NHS), segmented systems and systems based on mandatory insurance. The trend of reforms introduced in the 1990s and current proposals in almost all systems are directed towards adopting mandatory insurance via a basic packet of services and strengthening competition in providing services through a public and private mix. The organisation and structure of most systems studied have introduced and continue to introduce changes in line with international guidelines. The generality of these structures means that efforts must still be made to adopt designs strengthening them as instruments improving populations' quality of life. Comparative analysis is a tool leading to studying health systems and producing information which can nourish debate regarding current sector reform. This work took shape during the first approach to a comparative study of Andean region and Caribbean health systems.

Developing a framework to guide the de-adoption of low-value clinical practices in acute care medicine: a study protocol.

2017-01-19

Healthcare systems have difficulty incorporating scientific evidence into clinical practice, especially when science suggests that existing clinical practices are of low-value (e.g. ineffective or harmful to patients). While a number of lists outlining low-value practices in acute care medicine currently exist, less is known about how best to initiate and sustain the removal of low-value clinical practices (i.e. de-adoption). This study will develop a comprehensive list of barriers and facilitators to the de-adoption of low-value clinical practices in acute care facilities to inform the development of a framework to guide the de-adoption process. The proposed project is a multi-stage mixed methods study to develop a framework to guide the de-adoption of low-value clinical practices in acute care medicine that will be tested in a representative sample of acute care settings in Alberta, Canada. Specifically, we will: 1) conduct a systematic review of the de-adoption literature to identify published barriers and facilitators to the de-adoption of low-value clinical practices in acute care medicine and any associated interventions proposed (Phase one); 2) conduct focus groups with acute care stakeholders to identify important themes not published in the literature and obtain a comprehensive appreciation of stakeholder perspectives (Phase two); 3) extend the generalizability of focus group findings by conducting individual stakeholder surveys with a representative sample of acute care providers throughout the province to determine which barriers and facilitators identified in Phases one and two are most relevant in their clinical setting (Phase three). Identified barriers and facilitators will be catalogued and integrated with targeted interventions in a framework to guide the process of de-adoption in each of four targeted areas of acute care medicine (Emergency Medicine, Cardiovascular Health and Stroke, Surgery and Critical Care Medicine). Analyses will be descriptive using a combination of qualitative and quantitative analyses. There is a growing body of literature suggesting that the de-adoption of ineffective or harmful practices from patient care is integral to the delivery of high quality care and healthcare sustainability. The framework developed in this study will map barriers and facilitators to de-adoption to the most appropriate interventions, allowing stakeholders to effectively initiate, execute and sustain this process in an evidence-based manner.

The Aircraft Electric Taxi System: A Qualitative Multi Case Study

NASA Astrophysics Data System (ADS)

Johnson, Thomas Frank

The problem this research addresses is the airline industry, and the seemingly unwillingness attitude towards adopting ways to taxi aircraft without utilizing thrust from the main engines. The purpose of the study was to get a better understanding of the decision-making process of airline executives, in respect to investing in cost saving technology. A qualitative research method is used from personal interviews with 24 airline executives from two major U.S. airlines, related industry journal articles, and aircraft performance data. The following three research questions are addressed. RQ1. Does the cost of jet fuel influence airline executives' decision of adopting the aircraft electric taxi system technology? RQ2 Does the measurable payback period for a return on investment influence airline executives' decision of adopting ETS technology? RQ3. Does the amount of government assistance influence airline executives' decision of adopting ETS technology? A multi case research study design is used with a triangulation technique. The participant perceptions indicate the need to reduce operating costs, they have concerns about investment risk, and they are in favor of future government sponsored performance improvement projects. Based on the framework, findings and implications of this study, a future research paper could focus on the positive environmental effects of the ETS application. A study could be conducted on current airport area air quality and the effects that aircraft main engine thrust taxiing has on the surrounding air quality.

The therapeutic outcome for those with malignant glioma is poor, even though diverse therapeutic modalities have been developed. Immunotherapy has emerged as a therapeutic approach for malignant gliomas, making it possible to selectively treat tumors while sparing normal tissue. Here, we review clinical trials of adoptive immunotherapy approaches for malignant gliomas. We also describe a clinical trial that examined the efficacy and safety of autologous cytokine-induced killer (CIK) cells along with concomitant chemoradiotherapy for newly diagnosed glioblastoma. These CIK cells identify and kill autologous tumor cells. This review focuses on the use of adoptive immunotherapy for malignant gliomas and reviews the current literature on the concept of antitumor activity mediated by CIK cells.

Toxic prefibrillar α-synuclein amyloid oligomers adopt a distinctive antiparallel β-sheet structure.

2012-05-01

Parkinson's disease is an age-related movement disorder characterized by the presence in the mid-brain of amyloid deposits of the 140-amino-acid protein AS (α-synuclein). AS fibrillation follows a nucleation polymerization pathway involving diverse transient prefibrillar species varying in size and morphology. Similar to other neurodegenerative diseases, cytotoxicity is currently attributed to these prefibrillar species rather than to the insoluble aggregates. Nevertheless, the underlying molecular mechanisms responsible for cytotoxicity remain elusive and structural studies may contribute to the understanding of both the amyloid aggregation mechanism and oligomer-induced toxicity. It is already recognized that soluble oligomeric AS species adopt β-sheet structures that differ from those characterizing the fibrillar structure. In the present study we used ATR (attenuated total reflection)-FTIR (Fourier-transform infrared) spectroscopy, a technique especially sensitive to β-sheet structure, to get a deeper insight into the β-sheet organization within oligomers and fibrils. Careful spectral analysis revealed that AS oligomers adopt an antiparallel β-sheet structure, whereas fibrils adopt a parallel arrangement. The results are discussed in terms of regions of the protein involved in the early β-sheet interactions and the implications of such conformational arrangement for the pathogenicity associated with AS oligomers.

Can Smoke-Free Policies Reduce Tobacco Use Disparities of Sexual and Gender Minorities in Missouri?

2017-11-01

The purpose of this study is to explore the associations between smoke-free policies, current and former smoking status, personal smoking restrictions, and intention to quit among sexual and gender minority (SGM) and non-SGM individuals in Missouri. The current analysis derives from the Out, Proud and Healthy project. Chi-squares examined differences between SGM (N = 2210) and non-SGM (N = 586) respondents and former (N = 836) and current (N = 1960) smokers on smoking-related variables. Odds ratios and 95% confidence intervals from logistic regression identified variables associated with former (vs. current) smoking. SGM current smokers (25%) were significantly more likely than SGM former smokers (19%) to live in a community without a smoke-free policy. Among SGM current smokers, significantly greater intention to quit was seen in those living in a smoke-free community with a smoke-free policy of two or more years (94%) compared with those living in a community without a smoke-free policy (76%). Living in an area with smoke-free policies is related to greater intention to quit among SGM current smokers, greater support for smoke-free policies, and lower smoking prevalence for this community. The SGM community may collectively accrue greater public health benefits from the adoption of smoke-free policies than the non-SGM community. Prior to this study, no data are available regarding current and former smoking status among SGM individuals following the implementation of a local smoke-free policy. The purpose of this study was to explore the relationship between smoke-free policies, current and former smoking status, and intention to quit among SGM and non-SGM individuals in Missouri. This study finds evidence of lower current smoking prevalence and greater intentions to quit among SGM current smokers who live in communities with smoke-free policies. The SGM community may collectively accrue greater public health benefits from the adoption of smoke-free policies than the non-SGM community. © The Author 2017.

Abell, Cathy H; Keaster, Ric

2012-01-01

The purpose of this descriptive correlational research study was twofold: to examine the adoption of simulators in the nursing classroom and the relationship between adoption and nurse educators' perceptions of established change strategies as followed by program administrators. The use of simulators in education is important and requires many nurse educators to change their current teaching strategies. Data were collected from a purposive population using a demographic questionnaire, the nursing practice questionnaire (NPQ), and the change process survey. The overall diffusion score, as measured by the NPQ, was 2.6. A statistically significant correlation was noted between level of use and the perception of established change strategies being followed (r = .340, p < .01). Findings indicate that nurse educators adopt simulators sometimes when appropriate. Administrators of nursing programs can enhance this change by using established change strategies.

Innovation Adoption as Facilitated by a Change-Oriented Workplace

Becan, Jennifer Edwards; Knight, Danica K.; Flynn, Patrick M.

2011-01-01

One of the unique contributions of the current study is a glimpse into the process by which counselors decide to try new innovations in their clinical work. Data were collected from 421 counseling staff from 71 outpatient treatment programs in 4 US regions. Using hierarchical linear modeling, results reveal that the propensity to adopt workshop-based interventions is facilitated by two important mechanisms (1) an innovative organization with creative leadership and (2) change-oriented staff attributes (i.e., seeking professional growth, efficacy, adaptability, and influence on others). Innovative leaders and a climate receptive to change also bolster the development of these change-oriented attributes. One implication of these findings is the cascading effect of leaders’ support of innovative thinking and action resulting in employees strengthening their own adaptive skills and carrying this innovative thinking into individual adoption.

Data standards for clinical research data collection forms: current status and challenges.

PubMed

Richesson, Rachel L; Nadkarni, Prakash

2011-05-01

Case report forms (CRFs) are used for structured-data collection in clinical research studies. Existing CRF-related standards encompass structural features of forms and data items, content standards, and specifications for using terminologies. This paper reviews existing standards and discusses their current limitations. Because clinical research is highly protocol-specific, forms-development processes are more easily standardized than is CRF content. Tools that support retrieval and reuse of existing items will enable standards adoption in clinical research applications. Such tools will depend upon formal relationships between items and terminological standards. Future standards adoption will depend upon standardized approaches for bridging generic structural standards and domain-specific content standards. Clinical research informatics can help define tools requirements in terms of workflow support for research activities, reconcile the perspectives of varied clinical research stakeholders, and coordinate standards efforts toward interoperability across healthcare and research data collection.

Acetaminophen toxicity is common in clinical practice. In recent years, several European countries have lowered the treatment threshold, which has resulted in increased number of patients being treated at a questionable clinical benefit. The primary objective of this study is to estimate the cost and associated burden to the United States (U.S.) healthcare system, if such a change were adopted in the U.S. This study is a retrospective review of all patients age 14 years or older who were admitted to one of eight different hospitals located throughout the U.S. with acetaminophen exposures during a five and a half year span, encompassing from 1 January 2008 to 30 June 2013. Those patients who would be treated with the revised nomogram, but not the current nomogram were included. The cost of such treatment was extrapolated to a national level. 139 subjects were identified who would be treated with the revised nomogram, but not the current nomogram. Extrapolating these numbers nationally, an additional 4507 (95%CI 3641-8751) Americans would be treated annually for acetaminophen toxicity. The cost of lowering the treatment threshold is estimated to be $45 million (95%CI 36,400,000-87,500,000) annually. Adopting the revised treatment threshold in the U.S. would result in a significant cost, yet provide an unclear clinical benefit.

Negative Emotionality and Externalizing Problems in Toddlerhood: Overreactive Parenting as a Moderator of Genetic Influences

2011-01-01

The current study examined the interplay between parental overreactivity and children’s genetic backgrounds as inferred from birth parent characteristics on the development of negative emotionality during infancy, and in turn, to individual differences in externalizing problems in toddlerhood. The sample included 361 families linked through adoption (birth parents and adoptive families). Data were collected when the children were 9-, 18-, and 27-months old. Results indicated links between individual levels and changes in negative emotionality during infancy and toddlerhood to externalizing problems early in the third year of life. Findings also revealed an interaction between birth mother negative affect and adoptive mother overreactive parenting on children’s negative emotionality. This genotype × environment interaction predicted externalizing problems indirectly through its association with negative emotionality and revealed stronger effects of genetic risk for children with less overreactive parenting from their mothers. Limitations of this study and directions for future research are discussed. PMID:22293002

The objective of this mixed methods study was to examine current sexual risk behaviors, acceptability and potential adoption of pre-exposure prophylaxis (PrEP) for HIV prevention, and sexual behavior intentions with PrEP adoption among HIV-negative gay and bisexual men (GBM) in HIV serodiscordant relationships. A multiracial/ethnic sample of 25 HIV-negative GBM in serodiscordant relationships completed a qualitative interview and a brief interviewer-administered survey. A modified grounded theory approach was used to identify key themes relating to acceptability and future adoption of PrEP. Participants reported engaging in sexual risk behaviors that place them at risk for HIV infection. Participants also reported a high level of acceptability for PrEP and willingness to adopt PrEP for HIV prevention. Qualitative themes explaining future PrEP adoption included: (1) the opportunity to engage in sex using a noncondom HIV prevention method, (2) protection from HIV infection, and (3) less anxiety when engaging in sex with an HIV-positive partner. Associated with the future adoption of PrEP, a majority (64%) of participants indicated the likelihood for an increase in sexual risk behaviors and a majority (60%) of participants also indicated the likelihood for a decrease or abandonment of condom use, both of which are in contrast to the findings from the large iPrEx study. These findings suggest that the use of PrEP by HIV-negative GBM in serodiscordant relationships carries with it the potential for risk compensation. The findings suggest that PrEP only be offered as part of a comprehensive HIV prevention strategy that includes ongoing risk reduction counseling in the delivery of PrEP to help moderate risk compensation.

Communication for the development of pastoralism.

Communication is vital for the socio-economic and cultural development of pastoralists. If used constructively, communication can help to create a favourable environment for change and modernisation. This paper tries to uncover trends in communication as part of pastoral development, emphasising both indigenous and current methods of communication and prevailing constraints. This study reveals that pastoral development interventions in the past have often failed to achieve their goals, due to the centralised, 'top-down' approaches adopted and to reliance on external strategies and channels which ignored the indigenous knowledge and communications systems of pastoralists. Pastoralists have their own well-established communications systems for sharing information on climatic conditions and ecology, as well as economic, social and political issues. Modern communication technologies, especially radio and mobile telephones, are increasingly being used by pastoralists to access current regional information. However, pastoral development in the communications area is currently constrained by the failure of various development agencies and stakeholders to use participatory approaches, and by poor infrastructure and weak capacity. The authors therefore call for the adoption of more participatory and integrated approaches towards communication, the expansion of infrastructure and building of capacity.

State of offsite construction in India-Drivers and barriers

Arif, M.; Bendi, D.; Sawhney, A.; Iyer, K. C.

2012-05-01

The rapid growth of the construction industry in India has influenced key players in the industry to adopt alternative technologies addressing time, cost and quality. The rising demand in housing, infrastructure and other facilities have further highlighted the need for the construction industry to look at adopting alternate building technologies. Offsite construction has evolved as a panacea to dealing with the under-supply and poor quality in the current age construction industry. Several offsite techniques have been adopted by the construction sector. Although, different forms of offsite techniques have been around for a while but their uptake has been low in the Indian context. This paper presents the perceptions about offsite construction in India and highlights some of the barriers and drivers facing the Indian construction industry. The data was gathered through a survey of 17 high level managers from some of the largest stakeholder organizations of the construction sector in India. The influence of time and cost has been highlighted as a major factor fuelling the adoption of offsite construction. However, the influence of current planning systems and the need for a paradigm shift are some of the prominent barriers towards the adoption of offsite techniques.

Quantifying variety-specific heat resistance and the potential for adaptation to climate change.

The impact of climate change on crop yields has become widely measured; however, the linkages for winter wheat are less studied due to dramatic weather changes during the long growing season that are difficult to model. Recent research suggests significant reductions under warming. A potential adaptation strategy involves the development of heat resistant varieties by breeders, combined with alternative variety selection by producers. However, the impact of heat on specific wheat varieties remains relatively unstudied due to limited data and the complex genetic basis of heat tolerance. Here, we provide a novel econometric approach that combines field-trial data with a genetic cluster mapping to group wheat varieties and estimate a separate extreme heat impact (temperatures over 34 °C) across 24 clusters spanning 197 varieties. We find a wide range of heterogeneous heat resistance and a trade-off between average yield and resistance. Results suggest that recently released varieties are less heat resistant than older varieties, a pattern that also holds for on-farm varieties. Currently released - but not yet adopted - varieties do not offer improved resistance relative to varieties currently grown on farm. Our findings suggest that warming impacts could be significantly reduced through advances in wheat breeding and/or adoption decisions by producers. However, current adaptation-through-adoption potential is limited under a 1 °C warming scenario as increased heat resistance cannot be achieved without a reduction in average yields. © 2015 John Wiley & Sons Ltd.

Review of the current state of whole slide imaging in pathology

Whole slide imaging (WSI), or “virtual” microscopy, involves the scanning (digitization) of glass slides to produce “digital slides”. WSI has been advocated for diagnostic, educational and research purposes. When used for remote frozen section diagnosis, WSI requires a thorough implementation period coupled with trained support personnel. Adoption of WSI for rendering pathologic diagnoses on a routine basis has been shown to be successful in only a few “niche” applications. Wider adoption will most likely require full integration with the laboratory information system, continuous automated scanning, high-bandwidth connectivity, massive storage capacity, and more intuitive user interfaces. Nevertheless, WSI has been reported to enhance specific pathology practices, such as scanning slides received in consultation or of legal cases, of slides to be used for patient care conferences, for quality assurance purposes, to retain records of slides to be sent out or destroyed by ancillary testing, and for performing digital image analysis. In addition to technical issues, regulatory and validation requirements related to WSI have yet to be adequately addressed. Although limited validation studies have been published using WSI there are currently no standard guidelines for validating WSI for diagnostic use in the clinical laboratory. This review addresses the current status of WSI in pathology related to regulation and validation, the provision of remote and routine pathologic diagnoses, educational uses, implementation issues, and the cost-benefit analysis of adopting WSI in routine clinical practice.

Smoking cessation treatment practices described by the 5 A's (ask, advise, assess, assist, arrange) are not well applied at cardiology wards because of various reasons, such as a lack of time and appropriate skills of the nursing staff. Therefore, a simplified guideline proposing an ask-advise-refer (AAR) strategy was introduced in Dutch cardiac wards. This study aimed to identify factors that determine the intentions of cardiac ward heads in adopting the simplified AAR guideline, as ward heads are key decision makers in the adoption of new guidelines. Ward heads' perceptions of current smoking cessation practices at the cardiac ward were also investigated. A cross-sectional survey with written questionnaires was conducted among heads of cardiology wards throughout the Netherlands, of whom 117 (64%) responded. According to the heads of cardiac wards, smoking cessation practices by cardiologists and nurses were mostly limited to brief practices that are easy to conduct. Only a minority offered intensive counseling or arranged follow-up contact. Heads with strong intentions of adopting the AAR guideline differed significantly on motivational and organizational attributes and perceived more smoking cessation assistance by other health professionals than did heads with weak intentions of adopting. Positive attitudes, social support toward adoption, and perception of much assistance at the ward were significantly associated with increased intentions to adopt the AAR guideline. Brief smoking cessation practices are adequately performed at cardiac wards, but the most effective practices, offering assistance and arranging for follow-up, are less than optimal. The AAR guideline offers a more feasible approach for busy cardiology wards. To ensure successful adoption of this guideline, the heads of cardiac wards should be convinced of its advantages and be encouraged by a supportive work environment. Policies may also facilitate the adoption of the AAR guideline.

Little research has explored parental engagement in schools in the context of adoptive parent families or same-sex parent families. The current cross-sectional study explored predictors of parents’ self-reported school involvement, relationships with teachers, and school satisfaction, in a sample of 103 female same-sex, male same-sex, and heterosexual adoptive parent couples (196 parents) of kindergarten-age children. Parents who reported more contact by teachers about positive or neutral topics (e.g., their child’s good grades) reported more involvement and greater satisfaction with schools, regardless of family type. Parents who reported more contact by teachers about negative topics (e.g., their child’s behavior problems) reported better relationships with teachers but lower school satisfaction, regardless of family type. Regarding the broader school context, across all family types, parents who felt more accepted by other parents reported more involvement and better parent–teacher relationships; socializing with other parents was related to greater involvement. Regarding the adoption-specific variables, parents who perceived their children’s schools as more culturally sensitive were more involved and satisfied with the school, regardless of family type. Perceived cultural sensitivity mattered more for heterosexual adoptive parents’ relationships with their teachers than it did for same-sex adoptive parents. Finally, heterosexual adoptive parents who perceived high levels of adoption stigma in their children’s schools were less involved than those who perceived low levels of stigma, whereas same-sex adoptive parents who perceived high levels of stigma were more involved than those who perceived low levels of stigma. Our findings have implications for school professionals, such as school psychologists, who work with diverse families. PMID:25267169

Essentials for Successful and Widespread LED Lighting Adoption

NASA Astrophysics Data System (ADS)

Khan, Nisa

2011-03-01

Solid-state lighting (SSL), with light-emitting diodes (LEDs) as the light source, is a growing and essential field, particularly in regard to the heightened need for global energy efficiency. In recent years, SSL has experienced remarkable advances in efficiency, light output magnitude and quality. Thus such diverse applications as signage, message centers, displays, and special lighting are now adopting LEDs, taking 2010's market to 9.1 billion - 68% growth from the previous year! While this is promising, future growth in both display and lighting applications will rely upon unveiling deeper understanding and key innovations in LED lighting science and technologies. In this presentation, some LED lighting fundamentals, engineering challenges and novel solutions will be discussed to address reduction in efficiency (a.k.a. droop) at high currents, and to obtain uniform light distribution for overcoming LEDs' directional nature. The droop phenomenon has been a subject of much controversy in the industry and despite several studies and claims, a widely-accepted explanation still lacks because of counter arguments and experiments. Recently several research studies have identified that the droop behavior in nitride-based LEDs beyond certain current density ranges can only be comprehensively explained if the current leaking beyond the LED active region is included. Although such studies have identified a few useful current leakage mechanisms outside the active region, no one has included current leakage, due to non-ideal, 3-D device structures that create undesirable current distribution inside and outside the active region. This talk will address achieving desirable current distributions from optimized 3-D device structures that should reduce current leakage and hence the droop behavior. In addition to novel LED design solutions for droop reduction and uniform light distribution, the talk will address cost and yield concerns as they pertain to core material scarcity. Such solutions are expected to make LED lights more energy efficient, pleasant in appearance, longer-lasting, affordable, and thus suitable for green living.

Software Engineering Technology Infusion Within NASA

Zelkowitz, Marvin V.

1996-01-01

Abstract technology transfer is of crucial concern to both government and industry today. In this paper, several software engineering technologies used within NASA are studied, and the mechanisms, schedules, and efforts at transferring these technologies are investigated. The goals of this study are: 1) to understand the difference between technology transfer (the adoption of a new method by large segments of an industry) as an industry-wide phenomenon and the adoption of a new technology by an individual organization (called technology infusion); and 2) to see if software engineering technology transfer differs from other engineering disciplines. While there is great interest today in developing technology transfer models for industry, it is the technology infusion process that actually causes changes in the current state of the practice.

Problem behaviors of children adopted from the former Soviet Union.

McGuinness, Teena M; Pallansch, Leona

2007-01-01

Although current meta-analyses of problem behavior of internationally adopted children exist, few children adopted from the former Soviet Union have been included in these reports. A significant concern is that 13 children adopted from the former Soviet Union have died at the hands of their American adoptive parents since 1996. A cohort of 105 children adopted from the former Soviet Union has been assessed at two points in time by telephone and postal surveys to measure the impact of risk and protective factors on problem behavior. Pre-adoptive risk factors have declined in importance (except for birth weight) and protective factors (operationalized as aspects of family environment) have increased in influence over time. Problem behavior scores declined slightly at Time 2, despite the children having entered adolescence. Families play a significant role in the behavior of children adopted from the former Soviet Union. Nurses should counsel families to shape the child's environment during the transition from orphanage to homes in the United States, especially for children who are low birth weight.

The current state of electronic health record (EHR) use in Oklahoma.

2013-02-01

There is ample evidence of the positive impact of electronic health records (EHR) on operational efficiencies and quality of care. Yet, growth in the adoption of EHR and sharing of information among providers has been slow. The Health Information Technology for Economic and Clinical Health (HITECH) Act of 2009 provides financial incentives for eligible providers to adopt and implement EHR. Until now, little information was available regarding the use of EHR in Oklahoma. Sponsored by the Oklahoma Health Information Exchange Trust (OHIET), this study reveals that the frequency of use of EHR among Oklahoma providers is near the national average. Although a large number of Oklahoma physicians have received Medicaid incentive payments for planned adoption, implementation, or upgrade of EHR systems, relatively few eligible providers in Oklahoma have been certified to receive Medicare incentive payments through the Centers for Medicare and Medicaid Services (CMS) and even fewer have actually received these incentive payments.

Stages of Adoption Concern and Technology Acceptance in a Critical Care Nursing Unit.

Berg, Gina M; LoCurto, Jamie; Lippoldt, Diana

2017-09-01

The aim of this study is to examine the stages of concern (self, task, and impact) and usability (trust, perceived usefulness, and ease of use) shifts experienced by nurses adopting new technology. Patient care processes in critical care units can be disrupted with the incorporation of information technology. New users of technology typically transition through stages of concern and experience shifts in acceptance during assimilation. Critical care nurses (N = 41) were surveyed twice: (1) pre, immediately after training, and (2) post, 3 months after implementation of technology. From presurvey to postsurvey, self-concerns decreased 14%, whereas impact concerns increased 22%. Furthermore, there was a 30% increase in trust and a 17% increase in perceived usefulness, even with a 27% decrease in ease of use. Adoption of new technology requires critical care nurses to adapt current practices, which may improve trust and perceived usefulness yet decrease perceptions of ease of use.

Little work has examined parenting stress in adoptive parents, particularly lesbian and gay adoptive parents. The current longitudinal study examined parent-reported child characteristics (measured postplacement) and parent and family characteristics (measured preplacement) as predictors of postplacement parenting stress and change in parenting stress across three time points during the first 2 years of adoptive parenthood, among 148 couples (50 lesbian, 40 gay, and 58 heterosexual) who were first-time parents. Children in the sample were, on average, 5.61 months (SD = 10.26) when placed, and 2.49 years (SD = .85) at the 2 year postplacement follow-up. Findings revealed that parents who had been placed with older children and parents who perceived severe emotional/behavioral problems in their children reported more postplacement stress. In addition, parents who reported fewer depressive symptoms, more love for their partners, and more family and friend support during the preplacement period had less postplacement stress. Parenting stress decreased for parents who perceived severe emotional/behavioral problems in their children, but it increased somewhat for those who reported developmental problems in their children. Findings highlight vulnerabilities and resources that may shape adoptive parents' experiences of stress in early parenthood, and have implications for both researchers and professionals who wish to support adoptive family adjustment.

The incorporation of web-based learning into the dental curriculum has been consistently recommended in the literature on reform in dental education. There has been growing support for web-based learning in dental and dental hygiene education as demonstrated by deans’ identifying this as a planned curricular innovation. The purpose of our study was to explore characteristics of e-courses that may serve to increase adoption among dental and dental hygiene faculty members. Eight ninety-minute focus groups (three dental; five dental hygiene) were conducted with dental (n=27) and dental hygiene (n=23) faculty members from six academic institutions. The resulting data were analyzed to identify two overarching themes and associated subthemes with regard to benefits and barriers influencing adoption of e-courses. A working conceptual framework, based on the Diffusion of Innovations, was developed from these themes to understand the characteristics that may influence the rate of adoption of e-courses among dental and dental hygiene faculty members. Analysis of the data revealed four main adoption barriers: 1) low perceived relative advantage to faculty members; 2) low compatibility with current curriculum; 3) high perceived time commitment; and 4) complexity of e-course development. This exploratory assessment identifies leverage points for facilitating the adoption and sustainability of e-courses in dental and dental hygiene education. PMID:21546592

Gargiulo, J I; Eastwood, C R; Garcia, S C; Lyons, N A

2018-06-01

An increase in the average herd size on Australian dairy farms has also increased the labor and animal management pressure on farmers, thus potentially encouraging the adoption of precision technologies for enhanced management control. A survey was undertaken in 2015 in Australia to identify the relationship between herd size, current precision technology adoption, and perception of the future of precision technologies. Additionally, differences between farmers and service providers in relation to perception of future precision technology adoption were also investigated. Responses from 199 dairy farmers, and 102 service providers, were collected between May and August 2015 via an anonymous Internet-based questionnaire. Of the 199 dairy farmer responses, 10.4% corresponded to farms that had fewer than 150 cows, 37.7% had 151 to 300 cows, 35.5% had 301 to 500 cows; 6.0% had 501 to 700 cows, and 10.4% had more than 701 cows. The results showed that farmers with more than 500 cows adopted between 2 and 5 times more specific precision technologies, such as automatic cup removers, automatic milk plant wash systems, electronic cow identification systems and herd management software, when compared with smaller farms. Only minor differences were detected in perception of the future of precision technologies between either herd size or farmers and service providers. In particular, service providers expected a higher adoption of automatic milking and walk over weighing systems than farmers. Currently, the adoption of precision technology has mostly been of the type that reduces labor needs; however, respondents indicated that by 2025 adoption of data capturing technology for monitoring farm system parameters would be increased.

The present study sought to compare 4 groups of age- and gender-matched children-(a) those reared in institutions for children without parental care in Russia; (b) those raised by their biological parents in Russia; (c) those adopted to the United States from Russian institutions; and (d) those born in the United States and raised by their biological parents-on indicators of cognition, language, and early learning. In addition, we aimed to compare the effects of the length of time spent in an institution, the age of initial placement in an institution, the age at adoption, and pre-institutional risk factors (i.e., prenatal substance exposure and prematurity and low birth weight) on the above-mentioned outcomes in the 2 groups of children with institutionalization experiences. Our results confirm previous reports demonstrating negative consequences of institutionalization and substantial ameliorating effects of adoption. They also underscore the complexity of the effects of institutionalization and adoption, showing that they are intertwined with the effects of pre-institutional risk factors.

Bull, Tyler Preston; Malvey, Donna M; Szalma, James Leo

2016-01-01

Background While much is known about factors that facilitate telehealth adoption, less is known about why adoption does or does not occur in specific populations, such as students. Objective This study aims to examine the perceptions of telehealth systems within a large student sample. Methods Undergraduate students (N=315) participated in a survey of the perceived advantages and disadvantages of telehealth technologies. The responses to the survey were analyzed using thematic analysis. Results We found that students were likely to adopt telehealth systems for the following reasons: (1) the system worked efficiently, (2) the convenience of telehealth, and (3) to gain access to health services. Students also perceived several disadvantages to telehealth systems, such as issues of trust (ie, security, privacy), the impersonal nature of telehealth systems, and they were concerned about the potential for major system errors. Conclusion By understanding the current barriers to telehealth adoption in a cohort of students, we can not only better anticipate the future needs of this group, but also incorporate such needs into the design of future telehealth systems.

Studies examining the application of information technology to the delivery of health-care services often highlight the anticipated benefits. In consequence, the benefits of health-care information technology adoption, often referred to as 'e-health', are widely reported yet there is limited empirical evidence as to how such benefits can be realized. Design and implementation guidelines have been considered from a socio-technical perspective and there is support for the successful application of these principles. There are also some global surveys on the topic, but these often report only statistical data and lack richness of content. This study draws on existing literature to examine whether the principles of health-care information technology adoption are currently applied in practice. The paper presents a timely international analysis of the drivers, critical enablers and successful deployment strategies for e-health from the perspective of leading practitioners. The study considers the adoption of e-health in 15 countries. A qualitative research design was used and semistructured interviews were conducted with 38 thought leaders with expertise in health-care information systems and technology. The study presents a comparative analysis of the lessons learned from implementing, integrating and embedding e-health in practice, and presents a four-phase approach from the perspective of practitioners for the accelerated deployment of e-health systems: (i) develop a strategic approach, (ii) engage the workforce, (iii) capitalize on information technology and (iv) partner with the patient/citizen.

Objective The purpose of this study is to identify barriers that early-adopting dentists perceive as common and challenging when implementing recommendations from evidence-based (EB) clinical guidelines. Method This is a cross-sectional study. Dentists who attended the 2008 Evidence-based Dentistry Champion Conference were eligible for inclusion. Forty-three dentists (34%) responded to a 22-item questionnaire administered online. Two investigators independently coded and categorized responses to open-ended items. Descriptive statistics were computed to assess the frequency of barriers and perceived challenges. Results The most common barriers to implementation are difficulty in changing current practice model, resistance and criticism from colleagues, and lack of trust in evidence or research. Barriers perceived as serious problems have to do with lack of up-to-date evidence, lack of clear answers to clinical questions, and contradictory information in the scientific literature. Conclusions Knowledge of barriers will help improve translation of biomedical research for dentists. Information in guidelines needs to be current, clear, and simplified for use at chairside; dentists’ fears need to be addressed. PMID:21093800

Minimally invasive techniques are used more and more frequently. Since conventional laparoscopic approach has been the gold standard, surgeons in their effort to further reduce the invasiveness of conventional laparoscopic cholecystectomy have adopted Single Incision approach. The widespread adoption of robotics has led to the inevitable hybridization of robotic technology with laparoendoscopic single-site surgery (LESS). As a result, employment of the da Vinci surgical system may allow greater surgical maneuverability, improving ergonomics. A review of the English literature was conducted to evaluate all robotic single port cholecystectomy performed till today. Demographic data, operative parameters, postoperative outcomes and materials used for the operation were collected and assessed. A total of 12 studies, including 501 patients were analyzed. Demographics and clinical characteristics of the patients was heterogeneous, but in most studies a mean BMI <30 was recorded. Intraoperative metrics like operative time, estimated blood loss and conversion rate were comparable with those in multiport conventional laparoscopy. Robotic single port cholecystectomy is a safe and feasible alternative to conventional multiport laparoscopic or manual robotic approach. However, current data do not suggest a superiority of robotic SILC over other established methods.

Construction industrialization (CI) has been adopted worldwide because of its potential benefits. However, current research shows the incentives for adopting CI may differ in different regions. While the promotion of CI in China is still at the initial stage, a systematical analysis of the driving factors would help decision makers get a comprehensive understanding of CI development and select proper strategies to promote CI. This research combines qualitative and quantitative methods to explore the construction industrialization driving factors (CIDFs) in China. The grounded theory method (GTM) was employed to explore CI concepts among 182 CI-related articles published in 10 top-tier journals from 2000 to 2017. A total of 15 CIDFs were identified, including one suggested by professionals during a pre-test questionnaire survey. The analysis showed that the development of CI in China is pushed by macrodevelopment and pulled by the government and is also a self-driven process. The major driving factors for CI adoption in China are the transformation and upgrade of the conventional construction industry and the solution of development dilemmas. Our study also suggests that pilot programs are, currently, the most effective method to promote CI in China and to accumulate experience so to gain recognition by the society. This research is also of value for CI promotion in other developing countries.

2011-01-01

Objective To better understand barriers associated with the adoption and use of electronic prescribing of controlled substances (EPCS), a practice recently established by US Drug Enforcement Administration regulation. Materials and methods Prescribers of controlled substances affiliated with a regional health system were surveyed regarding current electronic prescribing (e-prescribing) activities, current prescribing of controlled substances, and expectations and barriers to the adoption of EPCS. Results 246 prescribers (response rate of 64%) represented a range of medical specialties, with 43.1% of these prescribers current users of e-prescribing for non-controlled substances. Reported issues with controlled substances included errors, pharmacy call-backs, and diversion; most prescribers expected EPCS to address many of these problems, specifically reduce medical errors, improve work flow and efficiency of practice, help identify prescription diversion or misuse, and improve patient treatment management. Prescribers expected, however, that it would be disruptive to practice, and over one-third of respondents reported that carrying a security authentication token at all times would be so burdensome as to discourage adoption. Discussion Although adoption of e-prescribing has been shown to dramatically reduce medication errors, challenges to efficient processes and errors still persist from the perspective of the prescriber, that may interfere with the adoption of EPCS. Most prescribers regarded EPCS security measures as a small or moderate inconvenience (other than carrying a security token), with advantages outweighing the burden. Conclusion Prescribers are optimistic about the potential for EPCS to improve practice, but view certain security measures as a burden and potential barrier. PMID:21946239

The future of health IT innovation and informatics: a report from AMIA's 2010 policy meeting

While much attention has been paid to the short-term impact that widespread adoption of health information technology (health IT) will have on the healthcare system, there is a corresponding need to look at the long-term effects that extant policies may have on health IT system resilience, innovation, and related ethical, social/legal issues. The American Medical Informatics Association's 2010 Health Policy Conference was convened to further the national discourse on the issues surrounding these longer-term considerations. Conference participants self-selected into three broad categories: resilience in healthcare and health IT; ethical, legal, and social challenges; and innovation, adoption, and sustainability. The discussions about problem areas lead to findings focusing on the lack of encouragement for long-term IT innovation that may result from current health IT policies; the potential impact of uneven adoption of health IT based on the exclusions of the current financial incentives; the weaknesses of contingency and risk mitigation planning that threaten system resilience; and evolving standards developed in response to challenges relating to the security, integrity, and availability of electronic health information. This paper discusses these findings and also offers recommendations that address the interwoven topics of innovation, resilience, and adoption. The goal of this paper is to encourage public and private sector organizations that have a role in shaping health information policy to increase attention to developing a national strategy that assures that health IT innovation and resilience are not impeded by shorter-term efforts to implement current approaches emphasizing adoption and meaningful use of electronic health records.

Denmark is widely regarded as a leading country in terms of eHealth integration and healthcare delivery services. The push for eHealth adoption over that past 20 years in the Danish health sector has led to the deployment of multiple eHealth technologies. However, in reality the Danish healthcare suffers from eHealth system fragmentation which has led to eHealth's inability to reach full potential in delivering quality healthcare service. This paper will presents a case study of the current state of eHealth in the Danish healthcare system and discuss the current challenges the country is facing today.

A strategic gaming model for health information exchange markets.

2018-03-01

Current market conditions create incentives for some providers to exercise control over patient data in ways that unreasonably limit its availability and use. Here we develop a game theoretic model for estimating the willingness of healthcare organizations to join a health information exchange (HIE) network and demonstrate its use in HIE policy design. We formulated the model as a bi-level integer program. A quasi-Newton method is proposed to obtain a strategy Nash equilibrium. We applied our modeling and solution technique to 1,093,177 encounters for exchanging information over a 7.5-year period in 9 hospitals located within a three-county region in Florida. Under a set of assumptions, we found that a proposed federal penalty of up to $2,000,000 has a higher impact on increasing HIE adoption than current federal monetary incentives. Medium-sized hospitals were more reticent to adopt HIE than large-sized hospitals. In the presence of collusion among multiple hospitals to not adopt HIE, neither federal incentives nor proposed penalties increase hospitals' willingness to adopt. Hospitals' apathy toward HIE adoption may threaten the value of inter-connectivity even with federal incentives in place. Competition among hospitals, coupled with volume-based payment systems, creates no incentives for smaller hospitals to exchange data with competitors. Medium-sized hospitals need targeted actions (e.g., outside technological assistance, group purchasing arrangements) to mitigate market incentives to not adopt HIE. Strategic game theoretic models help to clarify HIE adoption decisions under market conditions at play in an extremely complex technology environment.

2018-02-01

With the aging population and increase in chronic disease conditions, innovation to transform treatment pathways and service delivery will be necessary. The innovation adoption process however, can take 15 years before widespread adoption occurs in most healthcare systems. Current UK government policies to increase the facilitation of innovation adoption are under way. The aim of this study is to explore perceptions of tri-sectoral collaborations in the healthcare sector. The data in the study are drawn from a cross-sectional survey conducted in 2015 of professionals in academia, industry and the healthcare sectors in England, focusing on Diabetes care. Academia and healthcare respondents had the least work experience outside of their sectors compared to the industry respondents. Healthcare and academia respondents rated the industry sector less trustworthy, unethical, having different goals and less understanding of the other sectors. Industry respondents had a more positive perspective towards potential collaborators. The results from the study demonstrate greater potential challenges to tri-sectoral collaborations and the government's knowledge translation policy, due to pre-conceived notions and lack of understanding of other sectors. The purely structural approach of establishing government mandated translational networks may be insufficient without active attempts to improve collaborative relationships. Mechanisms to facilitate trust building and collaboration are proposed. Crown Copyright © 2017. Published by Elsevier B.V. All rights reserved.

Environmental market factors associated with electronic health record adoption among cancer hospitals.

Tarver, Will L; Menachemi, Nir

2017-02-22

Although recent literature has explored the relationship between various environmental market characteristics and the adoption of electronic health records (EHRs) among general, acute care hospitals, no such research currently exists for specialty hospitals, including those providing cancer care. The aim of the study was to examine the relationship between market characteristics and the adoption of EHRs among Commission on Cancer (CoC)-accredited hospitals. Secondary data on EHR adoption combined with hospital and environmental market characteristics were analyzed using logistic regression. Using the resource dependence theory, we examined how measures of munificence, complexity, and dynamism are related to the adoption of EHRs among CoC-accredited hospitals and, separately, hospitals not CoC-accredited. In a sample of 2,670 hospitals, 141 (0.05%) were academic-based CoC-accredited hospitals and 562 (21%) were community-based CoC-accredited hospitals. Measures of munificence such as cancer incidence rates (OR = 0.99, CI [0.99, 1.00], p = .020) and percentage population aged 65+ (OR = 0.99, CI [0.99, 1.00], p = .001) were negatively associated with basic EHR adoption, whereas urban location was positively associated with comprehensive EHR adoption (OR = 3.07, CI [0.89, 10.61], p = .076) for community-based CoC-accredited hospitals. Measures of complexity such as hospitals in areas with less competition were less likely to adopt a basic EHR (OR = 0.33, CI [0.19, 0.96], p = .005), whereas Medicare Managed Care penetration was positively associated with comprehensive EHR adoption (OR = 1.02, CI [1.00, 1.05], p = .070) among community-based CoC-accredited hospitals. Lastly, dynamism, measured as population change, was negatively associated with the adoption of comprehensive EHRs (OR = 0.99, CI [0.99, 1.00], p = .070) among academic-based CoC-accredited hospitals. A greater understanding of the environment's relationship to health information technology adoption in cancer hospitals will help stakeholders in these institutions make informed strategic decisions about information technology investments guided by their facilities' respective environmental factors. The results of this study may also be useful to hospital chief information officers and chief executive officers seeking to either improve their quality of care or achieve and maintain accreditation in providing cancer care.

Background. Given sparse knowledge on dissemination, this study sought to explore key benefits, barriers and contextual factors that are perceived to be important to the adoption and implementation of the ‘Community Guide's’ evidence-based physical activity recommendations. Design. We conducted case studies in two states where extensive adoption and implementation of the Guide's recommendations have occurred and in two states where widespread dissemination has lagged. Interviews (n = 76) were semi-structured and included both quantitative and qualitative methods. Participant perceptions from the following areas were examined: (i) priority of physical activity, (ii) awareness of and ability to define the term ‘evidence-based approaches’ and (iii) awareness, adoption, facilitators, benefits, challenges and barriers to Guide adoption. Results. Key enabling factors among high capacity states included: funds and direction from the Centers for Disease Control and Prevention; leadership support; capable staff; and successful partnerships and collaborations. Restraining forces among low capacity states included: the Guide recommendations being too new; participants being too new to current job; lack of time and training on how to use the Guide recommendations; limited funds and other resources and lack of leadership. Conclusion. To be effective, we must gain an understanding of contextual factors when designing for dissemination. PMID:20156839

Electronic prescribing for Schedule II through V controlled substances was legalized in the United States by the Drug Enforcement Administration in June 2010. However, little information exists about adoption and use of the electronic prescribing of controlled substances (EPCS) at the national level. Therefore, the objective of this study is to present the first information about national trends surrounding the adoption and use of the newly allowed EPCS by providers and pharmacies in the United States. Trends of EPCS adoption and use were examined for the number of EPCS, number of pharmacies enabled to accept EPCS, and the number of providers prescribing controlled substances electronically. Using nationally representative transactional Surescripts data from July 2012 to December 2013, we examined EPCS trends. During the study period, the total number of EPCS increased from 1535 to 52,423, and the number and percentage of all pharmacies enabled for EPCS increased from 8768 (13%) to 20,498 pharmacies (30%). The proportion of all providers prescribing controlled substances electronically is currently 1%, but increasing steadily each month. There is a positive national growth for EPCS in pharmacy preparedness to accept EPCS, the number of EPCS prescriptions sent each month, and the number of providers with the ability to send EPCS.

A research study was conducted (1) to examine the practices employed by US manufacturers to achieve productivity goals and (2) to understand what level of intelligent maintenance technologies and strategies are being incorporated into these practices. This study found that the effectiveness and choice of maintenance strategy were strongly correlated to the size of the manufacturing enterprise; there were large differences in adoption of advanced maintenance practices and diagnostics and prognostics technologies between small and medium-sized enterprises (SMEs). Despite their greater adoption of maintenance practices and technologies, large manufacturing organizations have had only modest success with respect to diagnostics and prognostics and preventive maintenance projects. The varying degrees of success with respect to preventative maintenance programs highlight the opportunity for larger manufacturers to improve their maintenance practices and use of advanced prognostics and health management (PHM) technology. The future outlook for manufacturing PHM technology among the manufacturing organizations considered in this study was overwhelmingly positive; many manufacturing organizations have current and planned projects in this area. Given the current modest state of implementation and positive outlook for this technology, gaps, future trends, and roadmaps for manufacturing PHM and maintenance strategy are presented.

Gunawan, B.; Neary, V. S.; Colby, J.

2012-12-01

A comprehensive tidal energy site characterization is performed using ADV measurements of instantaneous horizontal current magnitude and direction at the planned hub centerline of a tidal turbine over a two month period, and contributes to the growing data base of tidal energy site hydrodynamic conditions. The temporal variation, mean current statistics, and turbulence of the key tidal hydrodynamic parameters are examined in detail, and compared to estimates from two tidal energy sites in Puget Sound. Tidal hydrodynamic conditions, including mean annual current (at hub height), the speed of extreme gusts (instantaneous horizontal currents acting normal to the rotor plane), and turbulence intensity (as proposed here, relative to a mean current of 2 m s-1) can vary greatly among tidal energy sites. Comparison of hydrodynamic conditions measured in the East River tidal straight in New York City with those reported for two tidal energy sites in Puget Sound indicate differences of mean annual current speeds, difference in the instantaneous current speeds of extreme gusts, and differences in turbulence intensities. Significant differences in these parameters among the tidal energy sites, and with the tidal resource assessment map, highlight the importance of conducting site resource characterization with ADV measurements at the machine scale. As with the wind industry, which adopted an International Electrotechnical Commission (IEC) wind class standard to aid in the selection of wind turbines for a particular site, it is recommended that the tidal energy industry adopt an appropriate standard for tidal current classes. Such a standard requires a comprehensive field campaign at multiple tidal energy sites that can identify the key hydrodynamic parameters for tidal current site classification, select a list of tidal energy sites that exhibit the range of hydrodynamic conditions that will be encountered, and adopt consistent measurement practices (standards) for site classification.

Electronic medical records for otolaryngology office-based practice.

Chernobilsky, Boris; Boruk, Marina

2008-02-01

Pressure is mounting on physicians to adopt electronic medical records. The field of health information technology is evolving rapidly with innovations and policies often outpacing science. We sought to review research and discussions about electronic medical records from the past year to keep abreast of these changes. Original scientific research, especially from otolaryngologists, is lacking in this field. Adoption rates are slowly increasing, but more of the burden is shouldered by physicians despite policy efforts and the clear benefits to third-party payers. Scientific research from the past year suggests lack of improvements and even decreasing quality of healthcare with electronic medical record adoption in the ambulatory care setting. The increasing prevalence and standardization of electronic medical record systems results in a new set of problems including rising costs, audits, difficulties in transition and public concerns about security of information. As major players in healthcare continue to push for adoption, increased effort must be made to demonstrate actual improvements in patient care in the ambulatory care setting. More scientific studies are needed to demonstrate what features of electronic medical records actually improve patient care. Otolaryngologists should help each other by disseminating research about improvement in patient outcomes with their systems since current adoption and outcomes policies do not apply to specialists.

Adoption Factors of the Electronic Health Record: A Systematic Review

PubMed Central

2016-01-01

Background The Health Information Technology for Economic and Clinical Health (HITECH) was a significant piece of legislation in America that served as a catalyst for the adoption of health information technology. Following implementation of the HITECH Act, Health Information Technology (HIT) experienced broad adoption of Electronic Health Records (EHR), despite skepticism exhibited by many providers for the transition to an electronic system. A thorough review of EHR adoption facilitator and barriers provides ongoing support for the continuation of EHR implementation across various health care structures, possibly leading to a reduction in associated economic expenditures. Objective The purpose of this review is to compile a current and comprehensive list of facilitators and barriers to the adoption of the EHR in the United States. Methods Authors searched Cumulative Index of Nursing and Allied Health Literature (CINAHL) and MEDLINE, 01/01/2012–09/01/2015, core clinical/academic journals, MEDLINE full text, and evaluated only articles germane to our research objective. Team members selected a final list of articles through consensus meetings (n=31). Multiple research team members thoroughly read each article to confirm applicability and study conclusions, thereby increasing validity. Results Group members identified common facilitators and barriers associated with the EHR adoption process. In total, 25 adoption facilitators were identified in the literature occurring 109 times; the majority of which were efficiency, hospital size, quality, access to data, perceived value, and ability to transfer information. A total of 23 barriers to adoption were identified in the literature, appearing 95 times; the majority of which were cost, time consuming, perception of uselessness, transition of data, facility location, and implementation issues. Conclusions The 25 facilitators and 23 barriers to the adoption of the EHR continue to reveal a preoccupation on cost, despite incentives in the HITECH Act. Limited financial backing and outdated technology were also common barriers frequently mentioned during data review. Future public policy should include incentives commensurate with those in the HITECH Act to maintain strong adoption rates. PMID:27251559

To understand the evolving market of commercial off-the-shelf Computerized Physician Order Entry (CPOE) and Computerized Decision Support (CDS) applications and its effects on their uptake and implementation in English hospitals. Although CPOE and CDS vendors have been quick to enter the English market, uptake has been slow and uneven. To investigate this, the authors undertook qualitative ethnography of vendors and adopters of hospital CPOE/CDS systems in England. The authors collected data from semi-structured interviews with 11 individuals from 4 vendors, including the 2 most entrenched suppliers, and 6 adopter hospitals, and 21 h of ethnographic observation of 2 user groups, and 1 vendor event. The research and analysis was informed by insights from studies of the evolution of technology fields and the emergence of generic COTS enterprise solutions. Four key themes emerged: (1) adoption of systems that had been developed outside of England, (2) vendors' configuration and customization strategies, (3) localized adopter practices vs generic systems, and (4) unrealistic adopter demands. Evidence for our over-arching finding concerning the current immaturity of the market was derived from vendors' strategies, adopters' reactions to the technology, and policy makers' incomplete insights. The CPOE/CDS market in England is still in an emergent phase. The rapid entrance of diverse products, triggered by federal policy initiatives, has resulted in premature adoption of systems that do not yet adequately meet the needs of hospitals. Vendors and adopters lacked understanding of how to design and implement generic solutions to meet diverse user needs. © The Author 2015.

2016-06-01

[This paper is part of the Focused Collection on Preparing and Supporting University Physics Educators.] The physics education research community has produced a wealth of knowledge about effective teaching and learning of college level physics. Based on this knowledge, many research-proven instructional strategies and teaching materials have been developed and are currently available to instructors. Unfortunately, these intensive research and development activities have failed to influence the teaching practices of many physics instructors. This paper describes interim results of a larger study to develop a model of designing materials for successful propagation. The larger study includes three phases, the first two of which are reported here. The goal of the first phase was to characterize typical propagation practices of education developers, using data from a survey of 1284 National Science Foundation (NSF) principal investigators and focus group data from eight disciplinary groups of NSF program directors. The goal of the second phase was to develop an understanding of successful practice by studying three instructional strategies that have been well propagated. The result of the first two phases is a tentative model of designing for successful propagation, which will be further validated in the third phase through purposeful sampling of additional well-propagated instructional strategies along with typical education development projects. We found that interaction with potential adopters was one of the key missing ingredients in typical education development activities. Education developers often develop a polished product before getting feedback, rely on mass-market communication channels for dissemination, and do not plan for supporting adopters during implementation. The tentative model resulting from this study identifies three key propagation activities: interactive development, interactive dissemination, and support of adopters. Interactive development uses significant feedback from potential adopters to develop a strong product suitable for use in many settings. Interactive dissemination uses personal interactions to reach and motivate potential users. Support of adopters is missing from typical propagation practice and is important to reduce the burden of implementation and increases the likelihood of successful adoption.

The National Health Insurance Scheme (NHIS) in Nigeria was launched in 2005 as part of efforts by the federal government to achieve universal coverage using financial risk protection mechanisms. However, only 4% of the population, and mainly federal government employees, are currently covered by health insurance and this is primarily through the Formal Sector Social Health Insurance Programme (FSSHIP) of the NHIS. This study aimed to understand why different state (sub-national) governments decided whether or not to adopt the FSSHIP for their employees. This study used a comparative case study approach. Data were collected through document reviews and 48 in-depth interviews with policy makers, programme managers, health providers, and civil servant leaders. Although the programme's benefits seemed acceptable to state policy makers and the intended beneficiaries (employees), the feasibility of employer contributions, concerns about transparency in the NHIS and the role of states in the FSSHIP, the roles of policy champions such as state governors and resistance by employees to making contributions, all influenced the decision of state governments on adoption. Overall, the power of state governments over state-level health reforms, attributed to the prevailing system of government that allows states to deliberate on certain national-level policies, enhanced by the NHIS legislation that made adoption voluntary, enabled states to adopt or not to adopt the program. The study demonstrates and supports observations that even when the content of a programme is generally acceptable, context, actor roles, and the wider implications of programme design on actor interests can explain decision on policy adoption. Policy implementers involved in scaling-up the NHIS programme need to consider the prevailing contextual factors, and effectively engage policy champions to overcome known challenges in order to encourage adoption by sub-national governments. Policy makers and implementers in countries scaling-up health insurance coverage should, early enough, develop strategies to overcome political challenges inherent in the path to scaling-up, to avoid delay or stunting of the process. They should also consider the potential pitfalls of reforms that first focus on civil servants, especially when the use of public funds potentially compromises coverage for other citizens.

The current exploratory, qualitative study discovered and clarified implementation factors that led to technology adoption in long-term care (LTC). The Integrated Technology Implementation model guided the study of an electronic health record used in three LTC settings. Thirty key stakeholders (i.e., directors of nursing, nurses, and certified nurse aides) participated in focus groups or interviews. Findings indicated experiences were more similar than different among groups and facilities. Five major implementation themes supported by a variety of minor themes were identified. Implications for nursing include that leaders must be knowledgeable and committed to the change and engage staff throughout the implementation process. In addition, various communication and education strategies are required. [Journal of Gerontological Nursing, 43(10), 21-26.]. Copyright 2017, SLACK Incorporated.

We studied postinstitutionalized adopted Chinese girls to determine whether those with different variants of the MAOA gene promoter region (MAOA-VNTR) differed in their internalizing and externalizing behavior problems and whether the MAOA genotype moderated the relation between preadoption adversity and current behavior problems. MAOA genotyping was obtained for 94 girls (mean age: 9.2 years) and the number of 4-repeat (4R) alleles was determined (zero, one, or two). The adoptive mothers rated several indicators of preadoption adversity shortly after adoption (mean age at adoption 15.8 months) and completed the Child Behavior Checklist when the children were 8.1 years on average. No main effects were found for preadoption adversity. However, the MAOA genotype had a nominally significant effect (P<0.05) on internalizing problems. Regression analyses controlling for age, household income, authoritarian parenting, and family problems showed that among children with no physical signs of preadoption adversity, those carrying a greater number of 4R alleles scored significantly lower (P<0.01) on internalizing problems than those with fewer 4R alleles. Differences in internalizing scores related to the MAOA genotype were not observed for children who showed one or more physical signs of adversity at the time of adoption. A similar pattern was found for externalizing problems, although the results did not reach conventional levels of significance. Our results suggest that higher MAOA activity may be protective with respect to internalizing problems in internationally adopted Chinese girls, but that this protective effect decreases at higher levels of preadoption adversity. A similar pattern may exist for externalizing problems.

Background Home smoking bans significantly reduce the likelihood of secondhand smoke exposure among children and non-smoking adults. The purpose of this study was to examine national trends in a) the adoption of home smoking bans; b) discrepancies in parental smoking ban reports; and c) household and parental correlates of home smoking bans among households with underage children from 1995 to 2007. Methods We used data from the 1995/1996, 1998/1999, 2001/2002, 2003 and 2006/2007 Tobacco Use Supplement of the U.S. Current Population Survey to estimate prevalence rates and logistic regression models of parental smoking ban reports by survey period. Results Overall, the prevalence of a complete home smoking bans increased from 58.1% to 83.8% (p<0.01), while discrepancies in parental reports decreased from 12.5% to 4.6% (p<0.01) from 1995 to 2007. Households with single parent, low income, one or two current smokers, parents with less than a college education, or without infants were consistently less likely to report a home smoking ban over this period (p<0.05). Conclusion Despite general improvements in the adoption of home smoking bans and a reduction on parental discrepancies, disparities in the level of protection from secondhand smoke have persisted over time. Children living in households with single parents, low income, current smoker parents, less educated parents, or without infants are less likely to be protected by a home smoking ban. These groups are in need of interventions promoting the adoption of home smoking bans to reduce disparities in tobacco-related diseases. PMID:21813487

The dramaturgical perspective in relation to self and culture.

2014-11-01

Social scientists have studied human behavior from the dramaturgical perspective (DP), through which society is viewed as an elaborate play or game in which individuals enact different roles. The DP is more than a theoretical construct; members of individualist, secular societies occasionally adopt the DP with relation to their own lives. The current research examined the consequences of adopting the DP for evaluations of the self and conceptions of reality at large. Study 1 examined the attitudinal correlates of DP endorsement to test our claim that the DP is situated in an ideological context of individualism and secular modernism. Supporting our claim that the DP invalidates external information about the self's value, in Studies 2A and 2B individuals endorsed the DP to a greater extent after a self-esteem threat, and Studies 2C and 3 showed that exposure to the DP (but not a direct system threat) buffered self-esteem threats. Examining moderators of the DP's influence on self-esteem, Study 4 showed that taking the DP with regard to the ultimate value (vs. concrete experience) of a social role decreased self-esteem and investment in that role. Studies 5A and 5B examined the DP's consequences for perceived moral objectivism. Adopting the DP decreased moral objectivism and moralization of various behaviors but not when the intrinsic self was dispositionally or situationally salient. The latter finding suggests that although contemporary individuals can and occasionally do adopt a reflective stance toward their place within social reality, they nevertheless continue to believe in a true, core self that transcends that precarious drama.

Effects of electrode gap and electric current on chlorine generation of electrolyzed deep ocean water.

Electrolyzed water is a sustainable disinfectant, which can comply with food safety regulations and is environmental friendly. A two-factor central composite design was adopted for studying the effects of electrode gap and electric current on chlorine generation efficiency of electrolyzed deep ocean water. Deep ocean water was electrolyzed in a glass electrolyzing cell equipped with platinum-plated titanium anode and cathode in a constant-current operation mode. Results showed that current density, chlorine concentration, and electrolyte temperature increased with electric current, while electric efficiency decreased with electric current and electrode gap. An electrode gap of less than 11.7 mm, and a low electric current appeared to be a more energy efficient design and operation condition for the electrolysis system. Copyright © 2017.

2011-09-01

In this essay we develop and argue for the adoption of a more comprehensive model of research ethics than is included within current conceptions of responsible conduct of research (RCR). We argue that our model, which we label the ethical dimensions of scientific research (EDSR), is a more comprehensive approach to encouraging ethically responsible scientific research compared to the currently typically adopted approach in RCR training. This essay focuses on developing a pedagogical approach that enables scientists to better understand and appreciate one important component of this model, what we call intrinsic ethics. Intrinsic ethical issues arise when values and ethical assumptions are embedded within scientific findings and analytical methods. Through a close examination of a case study and its application in teaching, namely, evaluation of climate change integrated assessment models, this paper develops a method and case for including intrinsic ethics within research ethics training to provide scientists with a comprehensive understanding and appreciation of the critical role of values and ethical choices in the production of research outcomes.

A comparison of different powder compaction processes adopted for synthesis of lead-free piezoelectric ceramics

2016-04-01

Barium zirconium titanate, Ba(Zr0.15Ti0.85)O3 nano-crystalline powders were synthesized using high energy ball milling. The calcined powders were compacted adopting two different approaches viz. the conventional uniaxial pressing and cold-isostatic pressing (CIP) and the compacts were sintered at 1350 °C. A single phase perovskite structure was observed in both cases. BZT ceramics compacted using CIP technique exhibited enhanced dielectric and ferroelectric properties compared to ceramics compacted by uniaxial pressing. The polarization current peaks have been used in this paper as an experimental evidence to prove the existence of ferroelectricity in the BZT ceramics under study. The peak polarization current was found to be ~700% higher in case of cold iso-statically compacted ceramics. Similarly electric field induces strain showed a maximum strain ( S max) of 0.08% at an electric field of 28 kV/cm. The dielectric and ferroelectric properties observed are comparable to single crystals of the same material.

Distributed generation capabilities of the national energy modeling system

LaCommare, Kristina Hamachi; Edwards, Jennifer L.; Marnay, Chris

2003-01-01

This report describes Berkeley Lab's exploration of how the National Energy Modeling System (NEMS) models distributed generation (DG) and presents possible approaches for improving how DG is modeled. The on-site electric generation capability has been available since the AEO2000 version of NEMS. Berkeley Lab has previously completed research on distributed energy resources (DER) adoption at individual sites and has developed a DER Customer Adoption Model called DER-CAM. Given interest in this area, Berkeley Lab set out to understand how NEMS models small-scale on-site generation to assess how adequately DG is treated in NEMS, and to propose improvements or alternatives. Themore » goal is to determine how well NEMS models the factors influencing DG adoption and to consider alternatives to the current approach. Most small-scale DG adoption takes place in the residential and commercial modules of NEMS. Investment in DG ultimately offsets purchases of electricity, which also eliminates the losses associated with transmission and distribution (T&D). If the DG technology that is chosen is photovoltaics (PV), NEMS assumes renewable energy consumption replaces the energy input to electric generators. If the DG technology is fuel consuming, consumption of fuel in the electric utility sector is replaced by residential or commercial fuel consumption. The waste heat generated from thermal technologies can be used to offset the water heating and space heating energy uses, but there is no thermally activated cooling capability. This study consists of a review of model documentation and a paper by EIA staff, a series of sensitivity runs performed by Berkeley Lab that exercise selected DG parameters in the AEO2002 version of NEMS, and a scoping effort of possible enhancements and alternatives to NEMS current DG capabilities. In general, the treatment of DG in NEMS is rudimentary. The penetration of DG is determined by an economic cash-flow analysis that determines adoption based on the n umber of years to a positive cash flow. Some important technologies, e.g. thermally activated cooling, are absent, and ceilings on DG adoption are determined by some what arbitrary caps on the number of buildings that can adopt DG. These caps are particularly severe for existing buildings, where the maximum penetration for any one technology is 0.25 percent. On the other hand, competition among technologies is not fully considered, and this may result in double-counting for certain applications. A series of sensitivity runs show greater penetration with net metering enhancements and aggressive tax credits and a more limited response to lowered DG technology costs. Discussion of alternatives to the current code is presented in Section 4. Alternatives or improvements to how DG is modeled in NEMS cover three basic areas: expanding on the existing total market for DG both by changing existing parameters in NEMS and by adding new capabilities, such as for missing technologies; enhancing the cash flow analysis but incorporating aspects of DG economics that are not currently represented, e.g. complex tariffs; and using an external geographic information system (GIS) driven analysis that can better and more intuitively identify niche markets.« less

Di Marcantonio, P.; Baldini, V.; Calderone, G.; Cirami, R.; Coretti, I.; Cristiani, S.

Starting a few years ago, ESO initiated a number of projects aiming to explore the possible adoption of industrial standards and commercial off-the-shelf components (COTS) for the control of future VLT and E-ELT instrumentations. In this context, ESPRESSO, the next generation high-stability spectrograph for the VLT and to a certain extent, a precursor of HiRes, has adopted since the preliminary design phase those solutions. Based on the ESPRESSO experience and taking into account the requirements inferred from the preliminary Hi-Res studies in terms of both high-level operations as well as low-level control, I will present in this paper the current proposal for the HiRes hardware architecture.

Chicaybam, Leonardo; Bonamino, Martin Hernan

2014-10-01

Adoptive cell transfer (ACT) is emerging as a powerful modality of cancer treatment. While ACT has proved able to induce massive clinical responses, genetic modification of T lymphocytes further improved clinical responses obtained. One of the major current limitations of ACT is the inability to discern healthy from malignant cells, leading to on target/off tumor responses that can limit its application. We here discuss some of the approaches currently under development and potential solutions to circumvent these limitations and extend this potentially curative therapy to different tumors by targeting a variety of antigens.

Adoptive cell therapy for sarcoma

2015-01-01

Current therapy for sarcomas, though effective in treating local disease, is often ineffective for patients with recurrent or metastatic disease. To improve outcomes, novel approaches are needed and cell therapy has the potential to meet this need since it does not rely on the cytotoxic mechanisms of conventional therapies. The recent successes of T-cell therapies for hematological malignancies have led to renewed interest in exploring cell therapies for solid tumors such as sarcomas. In this review, we will discuss current cell therapies for sarcoma with special emphasis on genetic approaches to improve the effector function of adoptively transferred cells. PMID:25572477

A Systematic Review of Wearable Patient Monitoring Systems - Current Challenges and Opportunities for Clinical Adoption.

PubMed

Baig, Mirza Mansoor; GholamHosseini, Hamid; Moqeem, Aasia A; Mirza, Farhaan; Lindén, Maria

2017-07-01

The aim of this review is to investigate barriers and challenges of wearable patient monitoring (WPM) solutions adopted by clinicians in acute, as well as in community, care settings. Currently, healthcare providers are coping with ever-growing healthcare challenges including an ageing population, chronic diseases, the cost of hospitalization, and the risk of medical errors. WPM systems are a potential solution for addressing some of these challenges by enabling advanced sensors, wearable technology, and secure and effective communication platforms between the clinicians and patients. A total of 791 articles were screened and 20 were selected for this review. The most common publication venue was conference proceedings (13, 54%). This review only considered recent studies published between 2015 and 2017. The identified studies involved chronic conditions (6, 30%), rehabilitation (7, 35%), cardiovascular diseases (4, 20%), falls (2, 10%) and mental health (1, 5%). Most studies focussed on the system aspects of WPM solutions including advanced sensors, wireless data collection, communication platform and clinical usability based on a specific area or disease. The current studies are progressing with localized sensor-software integration to solve a specific use-case/health area using non-scalable and 'silo' solutions. There is further work required regarding interoperability and clinical acceptance challenges. The advancement of wearable technology and possibilities of using machine learning and artificial intelligence in healthcare is a concept that has been investigated by many studies. We believe future patient monitoring and medical treatments will build upon efficient and affordable solutions of wearable technology.

Healthcare organizations including residential care facilities (RCFs) are diversifying their services to meet market demands. Service innovations have been linked to the changes in the way that healthcare organizations organize their work. The objective of this study is to explore the relationship between organizational service innovations and Electronic Health Record (EHR) adoption in the RCFs. We used the data from the 2010 National Survey of Residential Care Facilities conducted by the Centers for Disease Control and Prevention. The outcome was whether an RCF adopted EHR or not, and the predictors were the organizational service innovations including provision of skilled nursing care and medication review. We also added facility characteristics as control variables. Weighted multivariate logistic regressions were used to estimate the relationship between service innovation factors and EHR adoption in the RCFs. In 2010, about 17.4% of the RCFs were estimated to use EHR. Multivariate analysis showed that RCFs employing service innovations were more likely to adopt EHR. The residential care facilities that provide skilled nursing services to their residents are more likely (OR: 1.42; 95% CI: 1.09-1.87) to adopt EHR. Similarly, RCFs with a provision of medication review were also more likely to adopt EHR (OR: 1.40; 95% CI: 1.00-1.95). Among the control variables, facility size, chain affiliation, ownership type, and Medicaid certification were significantly associated with EHR adoption. Our findings suggest that service innovations may drive EHR adoption in the RCFs in the United States. This can be viewed as a strategic attempt by RCFs to engage in a new business arrangement with hospitals and other health care organizations, where quality of care and interoperability of patients' records might play a vital role under the current healthcare reform. Future research could examine the relationship between service innovations and use of different EHR functionality in RCFs. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Rate of electronic health record adoption in South Korea: A nation-wide survey.

The adoption rate of electronic health record (EHR) systems in South Korea has continuously increased. However, in contrast to the situation in the United States (US), where there has been a national effort to improve and standardize EHR interoperability, no consensus has been established in South Korea. The goal of this study was to determine the current status of EHR adoption in South Korean hospitals compared to that in the US. All general and tertiary teaching hospitals in South Korea were surveyed regarding their EHR status in 2015 with the same questionnaire as used previously. The survey form estimated the level of adoption of EHR systems according to 24 core functions in four categories (clinical documentation, result view, computerized provider order entry, and decision supports). The adoption level was classified into comprehensive and basic EHR systems according to their functionalities. EHRs and computerized physician order entry systems were used in 58.1% and 86.0% of South Korean hospitals, respectively. Decision support systems and problem list documentation were the functions most frequently missing from comprehensive and basic EHR systems. The main barriers cited to adoption of EHR systems were the cost of purchasing (48%) and the ongoing cost of maintenance (11%). The EHR adoption rate in Korean hospitals (37.2%) was higher than that in US hospitals in 2010 (15.1%), but this trend was reversed in 2015 (58.1% vs. 75.2%). The evidence suggests that these trends were influenced by the level of financial and political support provided to US hospitals after the HITECH Act was passed in 2009. The EHR adoption rate in Korea has increased, albeit more slowly than in the US. It is logical to suggest that increased funding and support tied to the HITECH Act in the US partly explains the difference in the adoption rates of EHRs in both countries.

Implications of life-history strategies for obesity

PubMed Central

Maner, Jon K.; Dittmann, Andrea; Meltzer, Andrea L.; McNulty, James K.

2017-01-01

The association between low socioeconomic status (SES) and obesity is well documented. In the current research, a life history theory (LHT) framework provided an explanation for this association. Derived from evolutionary behavioral science, LHT emphasizes how variability in exposure to unpredictability during childhood gives rise to individual differences in a range of social psychological processes across the life course. Consistent with previous LHT research, the current findings suggest that exposure to unpredictability during childhood (a characteristic common to low SES environments) is associated with the adoption of a fast life-history strategy, one marked by impulsivity and a focus on short-term goals. We demonstrate that a fast life-history strategy, in turn, was associated with dysregulated weight-management behaviors (i.e., eating even in the absence of hunger), which were predictive of having a high body mass index (BMI) and being obese. In both studies, findings held while controlling for participants’ current socioeconomic status, suggesting that obesity is rooted in childhood experiences. A serial mediation model in study 2 confirmed that effects of childhood SES on adult BMI and obesity can be explained in part by exposure to unpredictability, the adoption of a fast life-history strategy, and dysregulated-eating behaviors. These findings suggest that weight problems in adulthood may be rooted partially in early childhood exposure to unpredictable events and environments. LHT provides a valuable explanatory framework for understanding the root causes of obesity. PMID:28739939

The current study is the first to investigate the school selection considerations and school-related experiences of sexual-minority parents with young children. The sample consisted of 210 parents in 105 couples, including 35 lesbian couples, 30 gay male couples, and 40 heterosexual couples, all of whom had adopted a child three years earlier. We found that parents with less income were more likely to consider cost in choosing a preschool, and parents with less education were more likely to consider location. More educated parents tended to emphasize racial diversity and the presence of adoptive families, and, among sexual-minority parents, the presence of other lesbian/gay parents. Sexual-minority parents were more likely to consider racial diversity than heterosexual parents. In reporting on their experiences with schools, heterosexual parents were more likely to perceive mistreatment due to their adoptive status than sexual-minority parents, and sexual-minority parents living in less gay-friendly communities were more likely to perceive mistreatment due to their sexual orientation than sexual-minority parents living in more gay-friendly communities. Our findings have implications for early childhood educators and administrators seeking to create an inclusive learning community for all types of families. PMID:27110062

A decade after promulgation of treatment guidelines by the Brain Trauma Foundation (BTF), few studies exist that examine the application of these guidelines for severe traumatic brain injury (TBI) patients. These studies have reported both cost savings and reduced mortality. We projected the results of previous studies of BTF guideline adoption to estimate the impact of widespread adoption across the United States. We used surveillance systems and national surveys to estimate the number of severely injured TBI patients and compared the lifetime costs of BTF adoption to the current state of treatment. After examining the health outcomes and costs, we estimated that a substantial savings in annual medical costs ($262 million), annual rehabilitation costs ($43 million) and lifetime societal costs ($3.84 billion) would be achieved if treatment guidelines were used more routinely. Implementation costs were estimated to be $61 million. The net savings were primarily because of better health outcomes and a decreased burden on lifetime social support systems. We also estimate that mortality would be reduced by 3,607 lives if the guidelines were followed. Widespread adoption of the BTF guidelines for the treatment of severe TBI would result in substantial savings in costs and lives. The majority of cost savings are societal costs. Further validation work to identify the most effective aspects of the BTF guidelines is warranted.

Creativity is an ability that plays a major role in the modern economy and society. It should represent an important component of the medical syllabus. However, it is often overlooked by the formal courses at universities. The current study aimed at evaluating whether the interactive educational models, recently adopted by the Faculty of Medicine and Surgery, at the University of Genoa, Italy, would favor the adoption of critical thinking, attitudes to changes, cultural diversity acceptance, and the adoption of relational soft skills versus traditional and frontal didactic teaching. Thirty students, who attended the last year of health care professional course at the Faculty of Medicine, volunteered to take part in the study and were randomly allocated to two groups: one group receiving an innovative, interactive excellence course and the other group receiving a more traditional approach. Ethnopsychiatry was chosen as the topic since it was hypothesized that it would have contributed to generation of a new approach toward diseases and patients. The first group of students, exposed to interactive lectures with the aim of promoting the adoption of critical thinking, were more satisfied than the second group. Participants who were involved in an active manner and had to work in small groups, actively finding their own solutions to solve the problems, perceived the utilized teaching method and experience more stimulating, involving, and effective. Implications for education policy makers are also envisaged. PMID:28496378

2016-01-01

Summary Objectives To help manage the risk of falls in home care, this study aimed to (i) identify home care clinicians’ information needs and how they manage missing or inaccurate data, (ii) identify problems that impact effectiveness and efficiency associated with retaining, exchanging, or processing information about fall risks in existing workflows and currently adopted health information technology (IT) solutions, and (iii) offer informatics-based recommendations to improve fall risk management interventions. Methods A case study was carried out in a single not-for-profit suburban Medicare-certified home health agency with three branches. Qualitative data were collected over a six month period through observations, semi-structured interviews, and focus groups. The Framework method was used for analysis. Maximum variation sampling was adopted to recruit a diverse sample of clinicians. Results Overall, the information needs for fall risk management were categorized into physiological, care delivery, educational, social, environmental, and administrative domains. Examples include a brief fall-related patient history, weight-bearing status, medications that affect balance, availability of caregivers at home, and the influence of patients’ cultures on fall management interventions. The unavailability and inaccuracy of critical information related to fall risks can delay necessary therapeutic services aimed at reducing patients’ risk for falling and thereby jeopardizing their safety. Currently adopted IT solutions did not adequately accommodate data related to fall risk management. Conclusion The results highlight the essential information for fall risk management in home care. Home care workflows and health IT solutions must effectively and efficiently retain, exchange, and process information necessary for fall risk management. Interoperability and integration of the various health IT solutions to make data sharing accessible to all clinicians is critical for fall risk management. Findings from this study can help home health agencies better understand their information needs to manage fall risks. PMID:27437035

[The new German general threshold limit value for dust--pro and contra the adoption in Austria].

2004-01-01

Since it has been realised that inhalation of inert dust is one of the important confounding variables for the development of chronic bronchitis, the threshold values for occupational exposure to these dusts needs to be further decreased. The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (MAK-Commission) has set a new threshold (MAK-Value) for inert dusts (4 mg/m3 for inhalable dust, 1.5 mg/m3 for respirable dust) in 1997. This value is much lower than the threshold values currently used world-wide. The aim of the present article is to assess the scientific plausibility of the methodology (databases and statistics) used to set these new German MAK-Values, regarding their adoption in Austria. Although we believe that it is substantial to lower the MAK-Value for inert dust in order to prevent the development of chronic bronchitis as a consequence of occupational exposure to inert dusts, the applied methodology used by the German MAK-Commission in 1997 to set the new MAK-Values does not justify the reduction of the threshold limit value. A carefully designed study to establish an appropriate scientific basis for setting a new threshold value for inert dusts in the workplace should be carried out. Meanwhile, at least the currently internationally applied threshold values should be adopted in Austria.

Current accounts of spatial cyberinfrastructure development tend to overemphasize technologies to the neglect of critical social and cultural issues on which adoption depends. Spatial cyberinfrastructures will have a higher chance of success if users of many types, including nonprofessionals, are made central to the development process. Recent studies in the history of infrastructures reveal key turning points and issues that should be considered in the development of spatial cyberinfrastructure projects. These studies highlight the importance of adopting qualitative research methods to learn how users work with data and digital tools, and how user communities form. The author's empirical research on data sharing networks in the Pacific Northwest salmon crisis at the turn of the 21st century demonstrates that ordinary citizens can contribute critical local knowledge to global databases and should be considered in the design and construction of spatial cyberinfrastructures.

The cellular and molecular principles that furnish the foundation for ACT of melanoma and their implications for further clinical research are reviewed. The parallel advances in basic immunology, preclinical animal studies, and clinical trials over the last two decades have been integrated successfully with improvements in technology to produce an effective ACT strategy for patients with melanoma. From the initial observation that tumors could be treated effectively by the transfer of immune cells to current strategies using preconditioning with myeloablative therapy before adoptive transfer of native or genetically altered T cells, the role of preclinical animal models is discussed. The importance of the pmel transgenic mouse model in the determination of the mechanisms of lymphodepletion, the ongoing work to identify the optimal T cells for adoptive immunotherapy, and the early impact of the emerging discipline of synthetic biology are highlighted.

Impaired ability of identifying mental states is a characteristic of schizophrenia spectrum disorders. In particular, people suffering from this illness tend to fail at attributing a belief to another, which has been linked to difficulties in changing interpersonal perspective. Following the view of Relational Frame Theory on perspective-taking skills, the current study aimed at examining the involvement of social anhedonia, one of the frequent features of schizophrenia, in the development of deficits in reversing the I-YOU relation (i.e., adopting the perspective of another). A task consisting of attributing a belief to another or to the self was employed with 30 non-clinical participants with a high level of social anhedonia and with 15 patients diagnosed with schizophrenia. In comparison to two control groups, both experimental groups showed significant poorer performance when adopting the perspective of another. These results constitute important indications to target specific relational repertoires when attempting to remediate impairments in mental states attribution linked to schizophrenia.

Emerging Trends in Healthcare Adoption of Wireless Body Area Networks.

2016-01-01

Real-time personal health monitoring is gaining new ground with advances in wireless communications. Wireless body area networks (WBANs) provide a means for low-powered sensors, affixed either on the human body or in vivo, to communicate with each other and with external telecommunication networks. The healthcare benefits of WBANs include continuous monitoring of patient vitals, measuring postacute rehabilitation time, and improving quality of medical care provided in medical emergencies. This study sought to examine emerging trends in WBAN adoption in healthcare. To that end, a systematic literature survey was undertaken against the PubMed database. The search criteria focused on peer-reviewed articles that contained the keywords "wireless body area network" and "healthcare" or "wireless body area network" and "health care." A comprehensive review of these articles was performed to identify adoption dimensions, including underlying technology framework, healthcare subdomain, and applicable lessons-learned. This article benefits healthcare technology professionals by identifying gaps in implementation of current technology and highlighting opportunities for improving products and services.

The current study examined two family process predictors of parent-reported child sleep problems at 4.5 years in an adoption sample: marital hostility and hostile parenting. Participants were 361 linked triads of birth parents, adoptive parents, and adopted children. We examined direct and indirect pathways from marital hostility to child sleep problems via hostile parenting. Mothers' marital hostility at 9 months was associated with child sleep problems at 4.5 years. Fathers' marital hostility at 9 months evidenced an indirect effect on child sleep problems at 4.5 years via fathers' hostile parenting at 27 months. Findings were significant even after controlling for genetic influences on child sleep (i.e., birth parent internalizing disorders). The findings suggest targets for prevention and intervention programs that are potentially modifiable (e.g., hostile parenting, marital hostility), and inform theory by demonstrating that relations among marital hostility, hostile parenting, and child sleep problems are significant after accounting for genetic influences.

To determine the current eyecare behaviour of dentists and compare this against published standards concerning frequency of sight test intervals and eye protection. Four hundred dentists were selected at random for inclusion in the study from the UK 2004 Dentists Register. They were invited to complete a questionnaire that ascertained their gender and age, current eyesight status and method of correction, elapsed time interval since their last eyesight test and reason for attendance. In addition, the use and power of magnification was sought along with the adoption of protective eyewear. Responses were coded and placed in a relational database to facilitate interrogation and subsequent statistical analysis. The questionnaire return rate was 63% (247 and allowing for the seven questionnaires returned marked unknown at this address). Of these 158 were males and 81 female. The majority worked in general dental practice. Those with known eyesight deficiencies were statistically more likely (p < 0.01) to attend for routine eye examination. Sixteen percent of respondents failed to attend for routine eye examination at least every two years. The mean age of those who had detected a change in their eyesight and sought examination was 43.59 (SD = 10.57) for males and 39.07 years (SD = 9.41) for females. This mirrored closely the mean age when the use of magnification was adopted (males = 42.39 (10.30), females = 40.33 (10.55)). The use of magnification was not universally adopted. Eye protection compliance was a low as 57% when using laboratory cutting equipment. Although compliance with accepted recommendations for biannual eyesight testing was higher than that for the general population, not all dentists complied. The adoption of protective eyewear was patchy and exposed dentists to unnecessary risk.

The purpose of this manuscript is to discuss the need for use of evidence based practice (EBP) in LTC, the current use of evidence in long term care facilities and what we know about adoption of the use of EBP in LTC. Literature review and reporting of findings from the M-TRAIN study that was a quasi-experimental design to test the effectiveness of an intervention to increase the use of EBPs for urinary incontinence and pain in 48 LTC facilities. Barriers to adopting EBPs include lack of available time, lack of access to current research literature, limited critical appraisal skills, excessive literature to review, non-receptive organizational culture, limited resources, and limited decision-making authority of staff to implement change. Strategies to promote adoption of EBP include the commitment of management; the culture of the home; leadership; staff knowledge, time, and reward; and facility size, complexity, the extent that members are involved outside the facility, NH chain membership, and high level of private pay residents. Findings from the M-TRAIN add, stability of nurse leader and congruency between the leaders perception of their leadership and the staff's perception of the leadership. There is clear evidence of the need and the benefits to residents of LTC and to the health care system yet adoption of EBP continues to be slow and sporadic. There is also evidence for the process of establishing best evidence and many resources to find the available EBPs. The urgent need now is finding ways to best get the EBPs implemented in LTC. There is growing evidence about best methods to do this but continued research is needed. Clearly, residents in LTC deserve the best care possible and EBPs represent an important vehicle by which to do this.

A variety of health-related genetic testing is currently advertized directly to consumers. This article provides a timely overview of direct-to-consumer genetic testing (DTC GT) and salient ethical issues, as well as an analysis of the impact of the recently adopted regulation on in vitro diagnostic medical devices on DTC GT. DTC GT companies currently employ new testing approaches, report on a wide spectrum of conditions and target new groups of consumers. Such activities raise ethical issues including the questionable analytic and clinical validity of tests, the adequacy of informed consent, potentially misleading advertizing, testing in children, research uses and commercialization of genomic data. The recently adopted regulation on in vitro diagnostic medical devices may limit the offers of predisposition DTC GT in the EU market.

Consumer research reveals considerable interest in the use of Personal Health Records (PHRs), yet adoption remains relatively low. Both adopters and nonadopters represent important perspectives from which to understand this paradox. This study focuses on direct feedback from adopters obtained using the American Customer Satisfaction Index (ACSI) survey on the My HealtheVet PHR portal (http://www.myhealth.va.gov) of the Veterans Health Administration (VHA). The results represent a source of direct feedback with which to better understand veterans' needs and preferences. The ACSI Survey was implemented in October 2007 to measure satisfaction and elicit information about characteristics and preferences of My HealtheVet PHR adopters. The data represent a continuous random sample of site visitors who have navigated at least four pages on the site. A total of 100 617 surveys were completed (17.2%). Satisfaction with My HealtheVet is high (8.3/10.0), and users are highly likely to return to the site (8.6/10.0) and recommend the site to other veterans (9.1/10.0). The majority of system adopters are male (91%), between the ages of 51 and 70 (68%), and served in the Vietnam War (60%). Most veterans currently visit the site to utilize pharmacy-related features. VHA has used the ACSI to monitor satisfaction, and to better understand the characteristics, needs, and preferences of early adopters. The data provide an important source of direct feedback to inform program development. Future research will include monitoring the impact of enhancements and new features on satisfaction, and conducting additional research with nonadopters to identify barriers to adoption and use.

Influence of perceived motivational climate on achievement goals in physical education: a structural equation mixture modeling analysis.

PubMed

Wang, J C; Liu, W C; Chatzisarantis, N L; Lim, C B

2010-06-01

The purpose of the current study was to examine the influence of perceived motivational climate on achievement goals in physical education using a structural equation mixture modeling (SEMM) analysis. Within one analysis, we identified groups of students with homogenous profiles in perceptions of motivational climate and examined the relationships between motivational climate, 2 x 2 achievement goals, and affect, concurrently. The findings of the current study showed that there were at least two distinct groups of students with differing perceptions of motivational climate: one group of students had much higher perceptions in both climates compared with the other group. Regardless of their grouping, the relationships between motivational climate, achievement goals, and enjoyment seemed to be invariant. Mastery climate predicted the adoption of mastery-approach and mastery-avoidance goals; performance climate was related to performance-approach and performance-avoidance goals. Mastery-approach goal had a strong positive effect while performance-avoidance had a small negative effect on enjoyment. Overall, it was concluded that only perception of a mastery motivational climate in physical education may foster intrinsic interest in physical education through adoption of mastery-approach goals.

A Korean fusion energy development promotion law (FEDPL) was enacted in 2007. As a following step, a conceptual design study for a steady-state Korean fusion demonstration reactor (K-DEMO) was initiated in 2012. After the thorough 0D system analysis, the parameters of the main machine characterized by the major and minor radii of 6.8 and 2.1 m, respectively, were chosen for further study. The analyses of heating and current drives were performed for the development of the plasma operation scenarios. Preliminary results on lower hybrid and neutral beam current drive are included herein. A high performance Nb3Sn-based superconducting conductor is adopted, providing a peak magnetic field approaching 16 T with the magnetic field at the plasma centre above 7 T. Pressurized water is the prominent choice for the main coolant of K-DEMO when the balance of plant development details is considered. The blanket system adopts a ceramic pebble type breeder. Considering plasma performance, a double-null divertor is the reference configuration choice of K-DEMO. For a high availability operation, K-DEMO incorporates a design with vertical maintenance. A design concept for K-DEMO is presented together with the preliminary design parameters.

Current National Approach to Healthcare ICT Standardization: Focus on Progress in New Zealand.

PubMed

Park, Young-Taek; Atalag, Koray

2015-07-01

Many countries try to efficiently deliver high quality healthcare services at lower and manageable costs where healthcare information and communication technologies (ICT) standardisation may play an important role. New Zealand provides a good model of healthcare ICT standardisation. The purpose of this study was to review the current healthcare ICT standardisation and progress in New Zealand. This study reviewed the reports regarding the healthcare ICT standardisation in New Zealand. We also investigated relevant websites related with the healthcare ICT standards, most of which were run by the government. Then, we summarised the governance structure, standardisation processes, and their output regarding the current healthcare ICT standards status of New Zealand. New Zealand government bodies have established a set of healthcare ICT standards and clear guidelines and procedures for healthcare ICT standardisation. Government has actively participated in various enactments of healthcare ICT standards from the inception of ideas to their eventual retirement. Great achievements in eHealth have already been realized, and various standards are currently utilised at all levels of healthcare regionally and nationally. Standard clinical terminologies, such as International Classification of Diseases (ICD) and Systematized Nomenclature of Medicine - Clinical Terms (SNOMED-CT) have been adopted and Health Level Seven (HL7) standards are actively used in health information exchanges. The government to New Zealand has well organised ICT institutions, guidelines, and regulations, as well as various programs, such as e-Medications and integrated care services. Local district health boards directly running hospitals have effectively adopted various new ICT standards. They might already be benefiting from improved efficiency resulting from healthcare ICT standardisation.

On the advantage of an external focus of attention: a benefit to learning or performance?

PubMed

Lohse, Keith R; Sherwood, David E; Healy, Alice F

2014-02-01

Although there is general agreement in the sport science community that the focus of attention (FOA) has significant effects on performance, there is some debate about whether or not the FOA adopted during training affects learning. A large number of studies on the focus of attention have shown that subjects who train with an external FOA perform better on subsequent retention and transfer tests. However, the FOA in these studies was not experimentally controlled during testing. Therefore, the current study used a dart-throwing paradigm in which the FOA was experimentally manipulated at both acquisition and testing over very short and long training times. Performance at test, in terms of accuracy and precision, was improved by adopting an external focus at test regardless of the focus instructed during acquisition, in both Experiment 1 and 2. Although an effect of acquisition focus during testing in Experiment 2 provides some evidence that FOA affects learning, the current data demonstrate a much stronger effect for performance than learning, and stronger effects of attention on precision than accuracy. Theoretical implications of these results are discussed, but in general these data provide a more nuanced understanding of how attentional focus instructions influence motor learning and performance.

2016-10-01

Interventions targeting children's dietary behavior often include strategies that target parents as implementation agents of change, though parent involvement on intervention effectiveness is unclear. The present study systematically assessed (1) reporting of reach, effectiveness, adoption, implementation and maintenance (RE-AIM) of child dietary intervention studies with parents as change agents and (2) evaluated within these studies the comparative effectiveness of interventions with and without a parent component. The search was conducted in PubMed, PsycINFO, and Cochrane Library. Eligible studies were required to include a condition with a parental component, a comparison/control group, and target a child dietary behavior outcome. Forty-nine articles met criteria. Raters extracted RE-AIM and parent implementation information for each study. Effectiveness (72.5%) was the highest reported RE-AIM element, followed by reach (27.5%), adoption (12.5%), implementation (10%), and maintenance (2.5%). Median reporting of parent implementation was highest for adoption and enactment (20%), followed by receipt (7.5%), and maintenance (2.5%). Six studies tested comparative effectiveness of parental involvement on child dietary outcomes. Current RE-AIM reporting among children's dietary interventions is inchoate. The contribution of parental involvement on intervention effectiveness remains unclear. Increased focus should be placed on reporting of external validity information, to enable better translation of research to practical applications. Copyright © 2016. Published by Elsevier Inc.

Beliefs, intentions, and beyond: A qualitative study on the adoption of sustainable gastrointestinal nematode control practices in Flanders' dairy industry.

PubMed

Vande Velde, F; Charlier, J; Hudders, L; Cauberghe, V; Claerebout, E

2018-05-01

Emerging anthelmintic resistance emphasizes the need for sustainable control approaches against gastrointestinal nematode (GIN) infections in cattle. The uptake of diagnostic methods for sustainable control could enable more informed treatments and reduce excessive anthelmintic use. Unfortunately, the adoption of such methods remains relatively poor. A better understanding of farmers' motivations and behaviour would help to develop applicable advises and communication strategies for sustainable worm control strategies. A previous study created a general model for adoption intention of GIN diagnostics on dairy farms and measured the most important factors driving this intention (Vande Velde et al., 2015). The current research aimed to dig deeper into this model for the beliefs underlying these factors, and to identify additional factors impelling this specific behaviour. Data were collected through 22 semi-structured interviews with dairy farmers. Using analytic induction analysis, data were moved between deduction and induction. Results show that the adoption process of diagnostic methods for GIN occurs through three different phases: adoption intention, actual adoption and maintenance. Low infection awareness and low priority ('top of mind') of the disease are important barriers for adopting sustainable GIN control. Secondly, farmer behaviour is guided by two important social norms: the opinion of their veterinarian and their fellow farmers. However, farmers hold an incongruent relationship with both norms throughout different stages of behaviour: they do not value other farmers' opinions as a positive reference (intention phase), but follow and mimic their behaviour as a group (action phase). The veterinarian is seen as the most important positive reference, but also the responsible actor for GIN control. As such, the farmers do not hold themselves responsible for implementing sustainable control strategies. Thirdly, different types of motivations influence different sorts of behaviours. Sustainable behaviour such as use of diagnostics will be influenced by moral motives, while management behaviour such as treatment is raised by more economic motives. Finally, not only performing, but also maintaining behaviour is important to fully address the adoption of sustainable control. As such, to maintain the adoption on farm, planning could be an important contribution. These insights can be used by animal health organizations and industry by exploiting motivations, social norms and planning to encourage the uptake of diagnostic approaches in GIN control.

2017-12-01

In the present work, pulsed current microplasma arc welding is carried out on AISI 321 austenitic stainless steel of 0.3 mm thickness. Peak current, Base current, Pulse rate and Pulse width are chosen as the input variables, whereas grain size and hardness are considered as output responses. Response surface method is adopted by using Box-Behnken Design, and in total 27 experiments are performed. Empirical relation between input and output response is developed using statistical software and analysis of variance (ANOVA) at 95% confidence level to check the adequacy. The main effect and interaction effect of input variables on output response are also studied.

McColl, K. G.

1994-02-01

The scope of regulations in the battery industry is extensive and also complex. In the future, regulations will become more demanding and will encompass issues not currently considered. Increased focus on environmental issues by government bodies, environmental groups, local communities will result in more strict compliance standards. The USA is currently leading the world's battery industries in the scope and compliance level of regulations. By studying trends in the USA, the rest of the battery industry can prepare itself for the future operating environment. This paper reviews the most critical areas of air pollution, blood-lead levels and recycling. The paper concludes that the battery industry must adopt a culture of exceeding current compliance standards.

The importance of patient engagement and the use of Social Media marketing in healthcare.

The present research aims to identify the application of social media for marketing or communication purposes in healthcare. We studied the opinion of healthcare professionals, organizations and health consumers, trying to identify the current status, trends and beliefs. The research reveals that healthcare organizations have to move forward and engage with their customers. The health consumers are more mature than the health providers. The descriptive characteristics of the sample's responses collected during the survey are presented. The current research tries to identify the application of social media for marketing or communication purposes in healthcare in Greece. The scope of the paper is to investigate the status in Greece and compare it with other countries. We studied the opinion of healthcare professionals, organizations and health consumers, trying to identify the current status, trends and beliefs. We formed adequate questionnaires which were distributed to the different target groups, while for statistical analysis we performed tests (in order to investigate the dependence between certain respondents' categories) as well as one-way ANOVA analysis for inference purposes. In this context, the results can depict the (average) behavior, as well as the homogeneity of the corresponding general population. The research conducted took into account the individualities of the Greek environment and revealed that both physicians and healthcare organizations have to move forward in order to engage with their customers. There is also a clear need to measure the effectiveness of any such media marketing effort. Most adopters are not yet-taking maximum advantage of the technology. Social networks are prevalent and several paradigms support their adoption for marketing purposes in the sensitive healthcare domain. Even though the expectations are ambitious, there is a lot of work to do in Greece in order to achieve the desired outcome. An important finding is that patients' attitudes are, in general, differentiated from those of healthcare professionals. Even though the results of the present paper can be generalized, according to the statistical analysis performed, further research would be warranted to cover all possible participants in the healthcare chain. It is clear that both physicians and healthcare organizations have to adopt social media marketing in their daily practice in order to meet the needs of their customers. The present paper advances the current state of knowledge, as there is not any prior study on this field in Greece.

2018-06-01

This study aims to investigate the longitudinal mode evolution of a InGaN green laser diode. A spectrometer with a 3-pm resolution was employed to obtain the emission spectra of a green laser diode, at a wavelength of around 520 nm, as a function of applied current and temperature. The spectral behavior of the laser modes with applied current was investigated. Right above the lasing threshold, the green diode laser emitted single longitudinal mode output. With increasing applied current, the number of the longitudinal modes increased. Up to ten lasing modes oscillated within the entire gain profile when the applied currents were tuned to 2.2Ith. Subsequently, a multi-Lorentzian profile model was adopted to analyze the spectra and observe how the modes evolved with temperature and applied current.

A qualitative study assessing the acceptability and adoption of implementing a results based financing intervention to improve maternal and neonatal health in Malawi.

Wilhelm, Danielle J; Brenner, Stephan; Muula, Adamson S; De Allegri, Manuela

2016-08-17

Results Based Financing (RBF) interventions have recently gained significant momentum, especially in sub-Saharan Africa. However, most of the research has focused on the evaluation of the impacts of this approach, providing little insight into how the contextual circumstances surrounding the implementation have contributed to its success or failure. This study aims to fill a void in the current literature on RBF by focusing explicitly on the process of implementing a RBF intervention rather than on its impact. Specifically, this study focuses on the acceptability and adoption of the RBF intervention's implementation among local and international key stakeholders with the aim to inform further implementation. The Results Based Financing for Maternal and Neonatal Health (RBF4MNH) Initiative is currently being implemented in Malawi. Our study employed an exploratory cross-sectional qualitative design to explore the factors affecting the acceptability and adoption of the intervention's implementation. Purposeful sampling techniques were used to identify each key stakeholder who participated in all or parts of the implementation process. In-depth interviews were conducted and analyzed using a deductive open coding approach. The final interpretation of the findings emerged through active discussion among the co-authors. Despite encountering several challenges, such as delay in procurement of equipment and difficulties in arranging local bank accounts, all stakeholders responded positively to the RBF4MNH Initiative. Stakeholders' acceptance of the RBF4MNH Initiative grew stronger over time as understanding of the intervention improved and was supported by early inclusion during the design and implementation process. In addition, stakeholders took on functions not directly incentivized by the intervention, suggesting that they turned adoption into actual ownership. All stakeholders raised concerns that the intervention may not be sustainable after its initial program phase would end, which contributed to hesitancy in fully accepting the intervention. Based on the results of this study, we recommend the inclusion of local stakeholders into the intervention's implementation process at the earliest stages. We also recommend setting up continuous feedback mechanisms to tackle challenges encountered during the implementation process. The sustainability of the intervention and its incorporation into national budgets should be addressed from the earliest stages.

Human embryonic stem cell-derived neurons adopt and regulate the activity of an established neural network

PubMed Central

Weick, Jason P.; Liu, Yan; Zhang, Su-Chun

2011-01-01

Whether hESC-derived neurons can fully integrate with and functionally regulate an existing neural network remains unknown. Here, we demonstrate that hESC-derived neurons receive unitary postsynaptic currents both in vitro and in vivo and adopt the rhythmic firing behavior of mouse cortical networks via synaptic integration. Optical stimulation of hESC-derived neurons expressing Channelrhodopsin-2 elicited both inhibitory and excitatory postsynaptic currents and triggered network bursting in mouse neurons. Furthermore, light stimulation of hESC-derived neurons transplanted to the hippocampus of adult mice triggered postsynaptic currents in host pyramidal neurons in acute slice preparations. Thus, hESC-derived neurons can participate in and modulate neural network activity through functional synaptic integration, suggesting they are capable of contributing to neural network information processing both in vitro and in vivo.

A high-voltage supply used on miniaturized RLG

NASA Astrophysics Data System (ADS)

Miao, Zhifei; Fan, Mingming; Wang, Yuepeng; Yin, Yan; Wang, Dongmei

2016-01-01

A high voltage power supply used in laser gyro is proposed in this paper. The power supply which uses a single DC 15v input and fly-back topology is adopted in the main circuit. The output of the power supply achieve high to 3.3kv voltage in order to light the RLG. The PFM control method is adopted to realize the rapid switching between the high voltage state and the maintain state. The resonant chip L6565 is used to achieve the zero voltage switching(ZVS), so the consumption is reduced and the power efficiency is improved more than 80%. A special circuit is presented in the control portion to ensure symmetry of the two RLG's arms current. The measured current accuracy is higher than 5‰ and the current symmetry of the two RLG's arms up to 99.2%.

The purpose of this study is to explore the current status of eHealth in Saudi Arabia from the perspective of health informatics professionals. We used a case study approach and analyzed participant data using thematic analysis. The study took place between July and August 2013. Data collection included interviews with nine senior health information professionals in Saudi Arabia. The findings describe participant views on current eHealth trends in Saudi Arabia and show differences among Saudi healthcare organizations in terms of eHealth adoption. Participants also describe the challenges relating to organizational and cultural issues, end user attitudes towards eHealth projects, and the lack of specialized human resources to implement eHealth systems. Two main recommendations made by the participants were to form a new national body for eHealth and to develop a unified plan for the implementation of Saudi eHealth initiatives.

Manufacture of tumor- and virus-specific T lymphocytes for adoptive cell therapies

2015-01-01

Adoptive transfer of tumor-infiltrating lymphocytes (TILs) and genetically engineered T lymphocytes expressing chimeric antigen receptors (CARs) or conventional alpha/beta T-cell receptors (TCRs), collectively termed adoptive cell therapy (ACT), is an emerging novel strategy to treat cancer patients. Application of ACT has been constrained by the ability to isolate and expand functional tumor-reactive T cells. The transition of ACT from a promising experimental regimen to an established standard of care treatment relies largely on the establishment of safe, efficient, robust and cost-effective cell manufacturing protocols. The manufacture of cellular products under current good manufacturing practices (cGMPs) has a critical role in the process. Herein, we review current manufacturing methods for the large-scale production of clinical-grade TILs, virus-specific and genetically modified CAR or TCR transduced T cells in the context of phase I/II clinical trials as well as the regulatory pathway to get these complex personalized cellular products to the clinic.

El Emam, Khaled

2006-01-01

Background Personal digital assistants (PDAs) find many uses in health care. Knowing rates of collective PDA use among health care providers is an important guiding step to further understanding those health care contexts that are most suited to PDA use and whether PDAs provide improved health outcomes. Objectives The objectives of this study were to estimate current and future PDA use among health care providers and to discuss possible implications of that use on choice of technology in clinical practice and research. Methods This study was a systematic review of PDA usage surveys. Surveys were identified as part of an ongoing systematic review on the use of handheld devices. Reports from eight databases covering both biomedical sciences and engineering (1993-2006) were screened against distinct eligibility criteria. Data from included surveys were extracted and verified in a standardized way and were assessed descriptively. Results We identified 23 relevant surveys, 15 of which were derived from peer-reviewed journals. This cohort of surveys was published between 2000 and 2005. Overall, since 1999, there is clear evidence of an increasing trend in PDA use. The current overall adoption rate for individual professional use ranges between 45% and 85%, indicating high but somewhat variable adoption, primarily among physicians. Conclusions Younger physicians and residents and those working in large and hospital-based practices are more likely to use a PDA. The adoption rate is now at its highest rate of increase according to a commonly accepted diffusion of innovations model. A common problem with the evaluation of information technology is that use frequently precedes research. This is the case here, in which PDA adoption rates are already high and projections are for rapid growth in the short term. In general, it appears that professional PDA use in health care settings involves more administrative and organizational tasks than those related to patient care, perhaps signaling where the growth in adoption is most likely to occur. We conclude that physicians are likely accustomed to using a PDA, and, therefore, technology expertise will probably not be a barrier to implementing PDA applications. However, there is an urgent need to evaluate the effectiveness and efficiency of specific tasks using handheld technology to inform those developing and those using PDA applications. PMID:16867970

Endoscopic submucosal dissection (ESD) is a well-established, minimally invasive treatment for superficial neoplasms of the gastrointestinal tract. The universal adoption of ESD has been limited by its slow learning curve, long procedure times, and high risk of complications. One technical challenge is the lack of a second hand that can provide traction, as in conventional surgery. Reliable tissue retraction that exposes the submucosal plane of dissection would allow for safer and more efficient dissection. Magnetic anchor guided endoscopic submucosal dissection (MAG-ESD) has potential benefits compared to other current traction methods. MAG-ESD offers dynamic tissue retraction independent of the endoscope mimicking a surgeon’s “second hand”. Two types of magnets can be used: electromagnets and permanent magnets. In this article we review the MAG-ESD technology, published work and studies of magnets in ESD. We also review the use of magnetic anchor guidance systems in natural orifice transluminal endoscopic surgery and the idea of magnetic non-contact retraction using surface ferromagentization. We discuss the current limitations, the future potential of MAG-ESD and the developments needed for adoption of this technology. PMID:28522906

A negative hydrogen (H{sup −}) ion source with hot cathode arc discharge was designed and fabricated as a primary injector for a 10 MeV PET cyclotron at IMP. 1 mA dc H{sup −} beam with ε {sub N,} {sub RMS} = 0.08 π mm mrad was extracted at 25 kV. Halbach hexapole was adopted to confine the plasma. The state of arc discharge, the parameters including filament current, arc current, gas pressure, plasma electrode bias, and the ratio of I{sub e{sup −}}/I{sub H{sup −}} were experimentally studied. The discussion on the result, and opinions to improve the source were given.

Phage therapy.

Housby, John N; Mann, Nicholas H

2009-06-01

There is a renaissance of interest in the antimicrobial potential of phages as more pathogens become multiply antibiotic resistant. Phage therapy is not a new concept, and it is important to ask why it is not part of the current repertoire of western medicine despite the fact that it has been continuously and extensively used in Eastern Europe for almost a century. Answering this question successfully will, largely, determine whether phage therapy can gain the credibility needed to overcome the scientific, financial and regulatory hurdles facing its adoption in mainstream clinical practice. Despite a paucity of such information from human studies, pharmacokinetic data and clinical outcomes from animal studies are currently providing convincing evidence for the safety and efficacy of phage therapy.

Cloud computing is the most promising current implementation of utility computing in the business world, because it provides some key features over classic utility computing, such as elasticity to allow clients dynamically scale-up and scale-down the resources in execution time. Nevertheless, cloud computing is still in its premature stage and experiences lack of standardization. The security issues are the main challenges to cloud computing adoption. Thus, critical industries such as government organizations (ministries) are reluctant to trust cloud computing due to the fear of losing their sensitive data, as it resides on the cloud with no knowledge of data location and lack of transparency of Cloud Service Providers (CSPs) mechanisms used to secure their data and applications which have created a barrier against adopting this agile computing paradigm. This study aims to review and classify the issues that surround the implementation of cloud computing which a hot area that needs to be addressed by future research.

In this study, the Dean Romanticism Scale and the Bachman Self-esteem Scale were administered to 121 teenagers between the ages of 12 and 19 in Southern California to investigate their degree of romanticism and self-esteem. The study also explored whether there was any relationship between the dependent variables of romanticism and self-esteem and ten independent variables--age, race, place of residence during pregnancy, age when first sexual intercourse occurred, age when pregnancy occurred, incidence of sexual abuse, incidence of abortion, adoption considerations, whether the subject was currently sexually active, and whether the teenager planned to have a child with the father of the baby. The results indicated that two variables were significantly related to feelings of romanticism--adoption considerations and whether the adolescent planned to have a child with the baby's father. In addition, two variables were significantly related to self-esteem--the incidence of sexual abuse and the incidence of abortion.

Healthcare stakeholders have a great interest in the adoption and use of electronic personal health records (ePHRs) because of the potential benefits associated with them. Little is known, however, about the level of adoption of ePHRs in Canada and there is limited evidence concerning their benefits and implications for the healthcare system. This study aimed to describe the current situation of ePHRs in Canada and explore stakeholder perceptions regarding barriers and facilitators to their adoption. Using a qualitative descriptive study design, we conducted semi-structured phone interviews between October 2013 and February 2014 with 35 individuals from seven Canadian provinces. The participants represented six stakeholder groups (patients, ePHR administrators, healthcare professionals, organizations interested in health technology development, government agencies, and researchers). A detailed summary of each interview was created and thematic analysis was conducted. We observed that there was no consensual definition of ePHR in Canada. Factors that could influence ePHR adoption were related to knowledge (confusion with other electronic medical records [EMRs] and lack of awareness), system design (usability and relevance), user capacities and attitudes (patient health literacy, education and interest, support for professionals), environmental factors (government commitment, targeted populations) and legal and ethical issues (information control and custody, confidentiality, privacy and security). ePHRs are slowly entering the Canadian healthcare landscape but provinces do not seem well-prepared for the implementation of this type of record. Guidance is needed on critical issues regarding ePHRs, such as ePHR definition, data ownership, access to information and interoperability with other electronic health records (EHRs). Better guidance on these issues would provide a greater awareness of ePHRs and inform stakeholders including clinicians, decision-makers, patients and the public. In turn, it may facilitate their adoption in the country. © 2016 by Kerman University of Medical Sciences

Background Numerous mental health apps have been developed and made available to users on the current app market. Users may find it difficult and overwhelming to select apps from the hundreds of choices that are available in the app marketplace. Clarifying what information cues may impact a user’s selection and adoption of mental health apps is now a critical and pressing issue. Objective The aim of this study was to investigate the impact of information cues on users’ adoption of anxiety apps using observational data from the Android app market. Methods A systematic search of anxiety apps was conducted on the Android app store by using keywords search. The title and metadata information of a total of 274 apps that met our criteria were collected and analyzed. Three trained researchers recorded the app rankings from the search results page on different dates and Web browsers. Results Our results show that ratings (r=.56, P<.001) and reviews (r=.39, P<.001) have significant positive correlations with the number of installs, and app prices have significant negative correlations with installs (r=−.36). The results also reveal that lower-priced apps have higher ratings (r=−.23, P<.001) and a greater number of app permission requests (r=.18, P=.002) from the device. For app titles, we found that apps with titles related to symptoms have significantly lower installs than apps with titles that are not related to symptoms (P<.001). Conclusions This study revealed a relationship between information cues and users’ adoption of mental health apps by analyzing observational data. As the first of its kind, we found impactful indicators for mental health app adoptions. We also discovered a labeling effect of app titles that could hinder mental health app adoptions and which may provide insight for future designs of mental health apps and their search mechanisms.

Rajamani, Sripriya; Roche, Erin; Soderberg, Karen; Bieringer, Aaron

2014-01-01

Background: Immunization information systems (IIS) operate in an evolving health care landscape with technology changes driven by initiatives such as the Centers for Medicare and Medicaid Services EHR incentive program, promoting adoption and use of electronic health record (EHR) systems, including standards-based public health reporting. There is flux in organizational affiliations to support models such as accountable care organizations (ACO). These impact institutional structure of how reporting of immunizations occurs and the methods adopted. Objectives: To evaluate the technical and organizational characteristics of healthcare provider reporting of immunizations to public health in Minnesota and to assess the adoption of standardized codes, formats and transport. Methods: Data on organizations and reporting status was obtained from Minnesota IIS (Minnesota Immunization Information Connection: MIIC) by collating information from existing lists, specialized queries and review of annual reports. EHR adoption data of clinics was obtained in collaboration with informatics office supporting the Minnesota e-Health Initiative. These data from various sources were merged, checked for quality to create a current state assessment of immunization reporting and results validated with subject matter experts. Results: Standards-based reporting of immunizations to MIIC increased to 708 sites over the last 3 years. A growth in automated real-time reporting occurred in 2013 with 143 new sites adopting the method. Though the uptake of message standards (HL7) has increased, the adoption of current version of HL7 and web services transport remains low. The EHR landscape is dominated by a single vendor (used by 40% of clinics) in the state. There is trend towards centralized reporting of immunizations with an organizational unit reporting for many sites ranging from 4 to 140 sites. Conclusion: High EHR adoption in Minnesota, predominance of a vendor in the market, and centralized reporting models present opportunities for better interoperability and also adaptation of strategies to fit this landscape. It is essential for IIS managers to have a good understanding of their constituent landscape for technical assistance and program planning purposes. PMID:25598866

Current trends in feminist nursing research.

Im, Eun-Ok

2010-01-01

Despite an increasing number of feminist studies in nursing, few reviews on current trends in feminist nursing research have been published. This article aims to explore the current trends in feminist nursing research and provide recommendations for future feminist studies in nursing. In multiple database searches, 207 articles were retrieved. These were reviewed based on 5 criteria: (1) epistemological background, (2) research questions, (3) research participants, (4) research methods, and (5) implications for changes. The review indicated that feminist nurse researchers with diverse epistemological backgrounds adopted new research methods to ask new questions; expanded their focus to include differences in ethnicity, class, sexual preference, and disability; and incorporated these diversities among women in a global context in their research. Based on these findings, recommendations for future feminist research in nursing are outlined. Copyright 2010 Mosby, Inc. All rights reserved.

Ethical Design of Intelligent Assistive Technologies for Dementia: A Descriptive Review.

2017-09-22

The use of Intelligent Assistive Technology (IAT) in dementia care opens the prospects of reducing the global burden of dementia and enabling novel opportunities to improve the lives of dementia patients. However, with current adoption rates being reportedly low, the potential of IATs might remain under-expressed as long as the reasons for suboptimal adoption remain unaddressed. Among these, ethical and social considerations are critical. This article reviews the spectrum of IATs for dementia and investigates the prevalence of ethical considerations in the design of current IATs. Our screening shows that a significant portion of current IATs is designed in the absence of explicit ethical considerations. These results suggest that the lack of ethical consideration might be a codeterminant of current structural limitations in the translation of IATs from designing labs to bedside. Based on these data, we call for a coordinated effort to proactively incorporate ethical considerations early in the design and development of new products.

Individual differences and workload effects on strategy adoption in a dynamic task.

The current study investigated the effects of individual differences and workload on strategy adaptivity in a complex, dynamic task called the Space Fortress game (Donchin, 1989). Participants learned to use a strategy of flying a ship in circles around the fortress in a standard game environment. Once they mastered the strategy, they were assigned to different workload conditions and transferred to a nonstandard environment in which a strong wind was introduced that made it more difficult to achieve a circular orbit. About half of the participants continued with their prior circular strategy while the rest adopted a novel strategy that achieved comparable performance with less effort. With this novel strategy, rather than trying to complete orbits they flew into the wind and then allowed the wind to blow them back to achieve a pendulum-like path. Participants without a working-memory load were more likely to adopt the new strategy. Participants were also more likely to adopt the new strategy if their pattern of behavior exposed them more often to the potential of drifting with the wind. The results indicate that spontaneous changes in strategy occur when people are exposed to the potential of a new strategy and have the cognitive resources to understand its potential.

Adoptive T cell immunotherapy is a promising approach to cancer treatment that currently has limited clinical applications. DNA methyltransferase inhibitors (DNAMTi) have known potential to affect the immune system through multiple mechanisms that could enhance the cytotoxic T cell responses, including: upregulation of tumor antigen expression, increased MHC class I expression, and blunting of myeloid derived suppressor cells (MDSCs) expansion. In this study, we have investigated the effect of combining the DNAMTi, decitabine, with adoptive T cell immunotherapy in the murine 4T1 mammary carcinoma model. We found that expression of neu, MHC class I molecules, and several murine cancer testis antigens (CTA) was increased by decitabine treatment of 4T1 cells in vitro. Decitabine also increased expression of multiple CTA in two human breast cancer cell lines. Decitabine-treated 4T1 cells stimulated greater IFN-gamma release from tumor-sensitized lymphocytes, implying increased immunogenicity. Expansion of CD11b + Gr1 + MDSC in 4T1 tumor-bearing mice was significantly diminished by decitabine treatment. Decitabine treatment improved the efficacy of adoptive T cell immunotherapy in mice with established 4T1 tumors, with greater inhibition of tumor growth and an increased cure rate. Decitabine may have a role in combination with existing and emerging immunotherapies for breast cancer.

The electronic health record is a key component of healthcare information systems. Currently, numerous hospitals have adopted electronic health records to replace paper-based records to document care processes and improve care quality. Integrating healthcare information system into traditional nursing daily operations requires time and effort for nurses to become familiarized with this new technology. In the stages of electronic health record implementation, smooth adoption can streamline clinical nursing activities. In order to explore the adoption process, a descriptive qualitative study design and focus group interviews were conducted 3 months after and 2 years after electronic health record system implementation (system aborted 1 year in between) in one hospital located in southern Taiwan. Content analysis was performed to analyze the interview data, and six main themes were derived, in the first stage: (1) liability, work stress, and anticipation for electronic health record; (2) slow network speed, user-unfriendly design for learning process; (3) insufficient information technology/organization support; on the second stage: (4) getting used to electronic health record and further system requirements, (5) benefits of electronic health record in time saving and documentation, (6) unrealistic information technology competence expectation and future use. It concluded that user-friendly design and support by informatics technology and manpower backup would facilitate this adoption process as well.

Associations between early life adversity and executive function in children adopted internationally from orphanages

Executive function (EF) abilities are increasingly recognized as an important protective factor for children experiencing adversity, promoting better stress and emotion regulation as well as social and academic adjustment. We provide evidence that early life adversity is associated with significant reductions in EF performance on a developmentally sensitive battery of laboratory EF tasks that measured cognitive flexibility, working memory, and inhibitory control. Animal models also suggest that early adversity has a negative impact on the development of prefrontal cortex-based cognitive functions. In this study, we report EF performance 1 y after adoption in 2.5- to 4-y-old children who had experienced institutional care in orphanages overseas compared with a group of age-matched nonadopted children. To our knowledge, this is the youngest age and the soonest after adoption that reduced EF performance has been shown using laboratory measures in this population. EF reductions in performance were significant above and beyond differences in intelligence quotient. Within the adopted sample, current EF was associated with measures of early deprivation after controlling for intelligence quotient, with less time spent in the birth family before placement in an institution and lower quality of physical/social care in institutions predicting poorer performance on the EF battery.

What Provisions Do Orthopaedic Programs Make for Maternity, Paternity, and Adoption Leave?

The process of choosing medical specialty and residency programs is multifaceted. Today's generation of medical students may have an increased interest in work-life balance and time with their families. In considering this factor, medical students may be influenced by policy regarding maternity, paternity, and adoption leave during residency and fellowship training. Current policy among orthopaedic programs regarding maternity, paternity, and adoption leave is not well described. To understand the influence these policies may have on the choices that medical students make in choosing their specialty, the policies must first be better understood. (1) What proportion of orthopaedic programs have formal or unwritten policies regarding maternity, paternity, and adoptive leave? (2) What are the provisions for time away, allotment of time, and makeup options for trainees who take leave? (3) What proportion of orthopaedic programs report utilization of leave, and what proportions of leave are for maternity, paternity, or adoptive reasons? Accredited programs in orthopaedic surgery were identified through the Council of Orthopedic Residency Directors within the American Orthopaedic Association. Current program directors of these accredited programs were surveyed. The survey was emailed to 144 program directors, of which 141 emails were delivered. Responses were received from 45 program directors, representing 31% of programs. The survey focused on maternity, paternity, and adoptive leave, and it consisted of questions designed to explore program policies (formal, unwritten, no policy, or in development), time considerations (amount allowed, allocation of time away, and makeup requirements), and utilization (trainees who took leave and type of leave used). Most respondents have maternity leave policy (formal: 36 of 45 [80%]; unwritten: 17 of 45 [38%]). Sixteen programs (16 of 45 [36%]) reported having both a formal and an unwritten maternity leave policy. Less than half of the programs have paternity leave policy (formal: 22 of 45 [49%]; unwritten: 19 of 45 [42%]), and fewer programs have adoption leave policy (formal: eight of 45 [18%]; unwritten: 11 of 45 [24%]). For programs that have formal or unwritten policies, most programs allow 4 to 6 weeks off (26 of 43 [60%]) with nearly half of programs allocating leave as paid time off (15 of 37 programs [41%]) and nearly half of programs requiring makeup time (17 of 37 [46%]). Many programs reported no utilization of leave by trainees (23 of 36 [61%]); many programs reported utilization by three or fewer residents (11 of 13 [85%]); and among residents who took leave, maternity was the most common reason (maternity: 22 of 36 [61%]; paternity: 11 of 36 [31%]; adoption: three of 36 [8%]). This study highlights the lack of uniformity among orthopaedic surgery residency and training programs regarding approach to maternity, paternity, and adoption leave. Discussion among program directors, perhaps facilitated by the Council of Orthopedic Residency Directors within the American Orthopaedic Association, to align the programs' policy in this arena may provide more transparent and uniform policy for trainees in orthopaedic surgery.

NOAA scientists and students in South Africa and the USA performed oceanographic experiments by deploying two surface drifting buoys in the Agulhas Current east of South Africa with the intent to determine the direction and path of each drifter's movement. The drifters were provided by the Global Drifter Program and the education component supported by the NOAA Adopt A Drifter Program (ADP). In a "surface dispersion" experiment, students in the classes that co-adopted the pair of surface drifters developed hypotheses about the drifters' paths, including whether they might drift into the Atlantic, Indian, Southern, or Pacific Oceans. They hypothesized why, when, and where the two drifters would separate. As part of the ADP, the collaborating schools tracked the drifters together via the internet. Several months after the drifters were deployed, a NOAA researcher discussed the surprising results with the collaborating students and teachers, including K-12 school children in George, Western Cape and Mossel Bay, South Africa and Bethesda, Maryland USA. One drifter pair had an interesting path. Although deployed in the center of the Agulhas Current, the pair became entrained in a submesoscale cyclonic vortex that formed as the jet flowed across the continental shelf break. The submesoscale vortex (with the drifter pair) then separated from the jet and leaked into the Atlantic Ocean. The eddy was visible in high-resolution satellite images of the sea surface temperature, but was not resolved in satellite altimetry fields. As discussed in a paper led by University of Cape Town graduate student Neil Malan currently under review, this implies that estimates of Agulhas leakage may be underestimated as they do not include this new pathway provided by submesoscale cyclonic vortices. Data from the adopted drifting buoys contribute to the Global Drifter Program, a component of the Global Ocean Observing System, and can be viewed from the NOAA Adopt a Drifter Program tracking page.

A wide range of assistive technologies have been developed to support the elderly population with the goal of promoting independent living. The adoption of these technology based solutions is, however, critical to their overarching success. In our previous research we addressed the significance of modelling user adoption to reminding technologies based on a range of physical, environmental and social factors. In our current work we build upon our initial modeling through considering a wider range of computational approaches and identify a reduced set of relevant features that can aid the medical professionals to make an informed choice of whether to recommend the technology or not. The adoption models produced were evaluated on a multi-criterion basis: in terms of prediction performance, robustness and bias in relation to two types of errors. The effects of data imbalance on prediction performance was also considered. With handling the imbalance in the dataset, a 16 feature-subset was evaluated consisting of 173 instances, resulting in the ability to differentiate between adopters and non-adopters with an overall accuracy of 99.42 %.

To gather information on the (a) types of wearable sensors, particularly personal activity monitors, currently used by occupational safety and health (OSH) professionals; (b) potential benefits of using such technologies in the workplace; and (c) perceived barriers preventing the widespread adoption of wearable sensors in industry. Wearable sensors are increasingly being promoted as a means to improve employee health and well-being, and there is mounting evidence supporting their use as exposure assessment and personal health tools. Despite this, many workplaces have been hesitant to adopt these technologies. An electronic survey was emailed to 28,428 registered members of the American Society of Safety Engineers (ASSE) and 1,302 professionals certified by the Board of Certification in Professional Ergonomics (BCPE). A total of 952 valid responses were returned. Over half of respondents described being in favor of using wearable sensors to track OSH-related risk factors and relevant exposure metrics at their respective workplaces. However, barriers including concerns regarding employee privacy/confidentiality of collected data, employee compliance, sensor durability, the cost/benefit ratio of using wearables, and good manufacturing practice requirements were described as challenges precluding adoption. The broad adoption of wearable technologies appears to depend largely on the scientific community's ability to successfully address the identified barriers. Investigators may use the information provided to develop research studies that better address OSH practitioner concerns and help technology developers operationalize wearable sensors to improve employee health and well-being.

Farmer Participation in U.S. Farm Bill Conservation Programs

Conservation policy in agricultural systems in the United States relies primarily on voluntary action by farmers. Federal conservation programs, including the Environmental Quality Incentives Program, offer incentives, both financial and technical, to farmers in exchange for adoption of conservation practices. Understanding motivations for (as well as barriers to) participation in voluntary programs is important for the design of future policy and effective outreach. While a significant literature has explored motivations and barriers to conservation practice adoption and participation in single programs, few studies in the U.S. context have explored general participation by farmers in one place and time. A mixed-methods research approach was utilized to explore farmer participation in all U.S. Farm Bill programs in Indiana. Current and past program engagement was high, with nearly half of survey respondents reporting participation in at least one program. Most participants had experience with the Conservation Reserve Program, with much lower participation rates in other programs. Most interview participants who had experience in programs were motivated by the environmental benefits of practices, with incentives primarily serving to reduce the financial and technical barriers to practice adoption. The current policy arrangement, which offers multiple policy approaches to conservation, offers farmers with different needs and motivations a menu of options. However, evidence suggests that the complexity of the system may be a barrier that prevents participation by farmers with scarce time or resources. Outreach efforts should focus on increasing awareness of program options, while future policy must balance flexibility of programs with complexity.

The Early Diffusion of Smart Meters in the US Electric Power Industry

NASA Astrophysics Data System (ADS)

Strong, Derek Ryan

The impact of new technologies within and across industries is only felt through their widespread diffusion, yet studies of technology diffusion are scarce compared to other aspects of the innovation process. The electric power industry is one industry that is currently undergoing substantial change as a result of both technological and institutional innovations. In this dissertation I examine the economic rationale for the adoption of smart meters by electric power utilities and the relationship between smart meters and the evolving electric power industry. I contribute to empirical research on technology diffusion by studying the early diffusion of smart meters in the US electric power industry. Using a panel dataset and econometric models, I analyze the determinants of both the interfirm and intrafirm diffusion of smart meters in the United States. The empirical findings suggest multiple drivers of smart meter diffusion. Policy and regulatory support have had a significant, positive impact on adoption but have not been the only relevant determinants. The findings also suggest that utility characteristics and some combination of learning, cost reductions, and technology standards have been important determinants affecting smart meter diffusion. I also explore the policy implications resulting from this analysis for enhancing the diffusion of smart meters. The costs and benefits of adopting smart meters have been more uncertain than initially thought, suggesting that some policy support for adoption was premature. The coordination of policies is also necessary to achieve the full benefits of using smart meters.

Homing to solid cancers: a vascular checkpoint in adoptive cell therapy using CAR T-cells.

The success of adoptive T-cell therapies for the treatment of cancer patients depends on transferred T-lymphocytes finding and infiltrating cancerous tissues. For intravenously transferred T-cells, this means leaving the bloodstream (extravasation) from tumour blood vessels. In inflamed tissues, a key event in extravasation is the capture, rolling and arrest of T-cells inside blood vessels which precedes transmigration across the vessel wall and entry into tissues. This depends on co-ordinated signalling of selectins, integrins and chemokine receptors on T-cells by their respective ligands which are up-regulated on inflamed blood vessels. Clinical data and experimental studies in mice suggest that tumour blood vessels are anergic to inflammatory stimuli and the recruitment of cytotoxic CD8(+)T-lymphocytes is not very efficient. Interestingly, and somewhat counter-intuitively, anti-angiogenic therapy can promote CD8(+)T-cell infiltration of tumours and increase the efficacy of adoptive CD8(+)T-cell therapy. Rather than inhibit tumour angiogenesis, anti-angiogenic therapy 'normalizes' (matures) tumour blood vessels by promoting pericyte recruitment, increasing tumour blood vessel perfusion and sensitizing tumour blood vessels to inflammatory stimuli. A number of different approaches are currently being explored to increase recruitment by manipulating the expression of homing-associated molecules on T-cells and tumour blood vessels. Future studies should address whether these approaches improve the efficacy of adoptive T-cell therapies for solid, vascularized cancers in patients. © 2016 Authors; published by Portland Press Limited.

This study examined the role of prospective payment systems in the adoption of new medical technologies across different countries. A literature review was conducted to provide background for the study and guide development of a survey instrument. The survey was disseminated to hospital payment systems experts in 15 jurisdictions. Fifty-one surveys were disseminated, with 34 returned. The surveys returned covered 14 of the 15 jurisdictions invited to participate. The majority (71%) of countries update the patient classification system and/or payment tariffs on an annual basis to try to account for new technologies. Use of short-term separate or supplementary payments for new technologies occurs in 79% of countries to ensure adequate funding and facilitate adoption. A minority (43%) of countries use evidence of therapeutic benefit and/or costs to determine or update payment tariffs, although it is somewhat more common in establishing short-term payments. The main barrier to using evidence is uncertain or unavailable clinical evidence. Almost three-fourths of respondents believed diagnosis-related group systems incentivize or deter technology adoption, depending on the particular circumstances. Improvements are needed, such as enhanced strategies for evidence generation and linking evidence of value to payments, national and international collaboration and training to improve existing practice, and flexible timelines for short-term payments. Importantly, additional research is needed to understand how different payment policies impact technology uptake as well as quality of care and costs.

Adoptive immunotherapy for hematological malignancies using T cells gene-modified to express tumor antigen-specific receptors.

PubMed

Fujiwara, Hiroshi

2014-12-15

Accumulating clinical evidence suggests that adoptive T-cell immunotherapy could be a promising option for control of cancer; evident examples include the graft-vs-leukemia effect mediated by donor lymphocyte infusion (DLI) and therapeutic infusion of ex vivo-expanded tumor-infiltrating lymphocytes (TIL) for melanoma. Currently, along with advances in synthetic immunology, gene-modified T cells retargeted to defined tumor antigens have been introduced as "cellular drugs". As the functional properties of the adoptive immune response mediated by T lymphocytes are decisively regulated by their T-cell receptors (TCRs), transfer of genes encoding target antigen-specific receptors should enable polyclonal T cells to be uniformly redirected toward cancer cells. Clinically, anticancer adoptive immunotherapy using genetically engineered T cells has an impressive track record. Notable examples include the dramatic benefit of chimeric antigen receptor (CAR) gene-modified T cells redirected towards CD19 in patients with B-cell malignancy, and the encouraging results obtained with TCR gene-modified T cells redirected towards NY-ESO-1, a cancer-testis antigen, in patients with advanced melanoma and synovial cell sarcoma. This article overviews the current status of this treatment option, and discusses challenging issues that still restrain the full effectiveness of this strategy, especially in the context of hematological malignancy.

Over the last two decades, many states have adopted several of the 20 laws that aim to control youth access to and possession of alcohol and prevent underage drinking in the United States. However, many of these laws have not been evaluated since their adoption. The objective of this study was to determine which minimum legal drinking age 21 (MLDA-21) laws currently have an effect on underage drinking-and-driving fatal crashes. We updated the effective dates of the 20 MLDA-21 laws examined in this study and used scores of each law's strengths and weaknesses. Our structural equation model included the 20 MLDA-21 laws, impaired driving laws, seat belt safety laws, economic strength, driving exposure, beer consumption, and fatal crash ratios of drinking-to-nondrinking drivers under age 21. Nine MLDA-21 laws were associated with significant decreases in fatal crash ratios of underage drinking drivers: possession of alcohol (-7.7%), purchase of alcohol (-4.2%), use alcohol and lose your license (-7.9%), zero tolerance .02 blood alcohol concentration limit for underage drivers (-2.9%), age of bartender ≥21 (-4.1%), state responsible beverage service program (-3.8%), fake identification support provisions for retailers (-11.9%), dram shop liability (-2.5%), and social host civil liability (-1.7%). Two laws were associated with significant increases in the fatal crash ratios of underage drinking drivers: prohibition of furnishing alcohol to minors (+7.2%) and registration of beer kegs (+9.6%). The nine effective MLDA-21 laws are estimated to be currently saving approximately 1,135 lives annually, yet only five states have enacted all nine laws. If all states adopted these nine effective MLDA-21 laws, it is estimated that an additional 210 lives could be saved every year.

The 2014 International Pressure Ulcer Prevention (PUP) Clinical Practice Guidelines (CPG) provides the most current evidence based strategies to prevent Pressure Ulcer (PU). The evidence upon which these guidelines have been developed has predominantly been generated from research conducted in developed countries. Some of these guidelines may not be feasible in developing countries due to structural and resource issues; therefore there is a need to adapt these guidelines to the context thus making it culturally acceptable. To present a protocol detailing the tailoring of international PUPCPG into a care bundle for the Nigerian context. Guided by the Knowledge to Action (KTA) framework, a two phased study will be undertaken. In Phase 1, the Delphi technique with stakeholder leaders will be used to review the current PUPCPG, identifying core strategies that are feasible to be adopted in Nigeria. These core strategies will become components of a PUP care bundle. In Phase 2, key stakeholder interviews will be used to identify the barriers, facilitators and potential implementation strategies to promote uptake of the PUP care bundle. A PUP care bundle, with three to eight components is expected to be developed from Phase 1. Implementation strategies to promote adoption of the PUP care bundle into clinical practice in selected Nigerian hospitals, is expected to result from Phase 2. Engagement of key stakeholders and consumers in the project should promote successful implementation and translate into better patient care. Using KTA, a knowledge translation framework, to guide the implementation of PUPCPG will enhance the likelihood of successful adoption in clinical practice. In implementing a PUP care bundle, developing countries face a number of challenges such as the feasibility of its components and the required resources.

Clinical information systems have long been used in intensive care units but reports on their adoption and benefits are limited. This study evaluated a Critical Care Information System implementation. A case study summative evaluation was conducted, employing observation, interview, and document analysis in operating theatres and 16-bed adult intensive care units in a 400-bed Malaysian tertiary referral centre from the perspectives of users (nurses and physicians), management, and information technology staff. System implementation, factors influencing adoption, fit between these factors, and the impact of the Critical Care Information System were evaluated after eight months of operation. Positive influences on system adoption were associated with technical factors, including system ease of use, usefulness, and information relevancy; human factors, particularly user attitude; and organisational factors, namely clinical process-technology alignment and champions. Organisational factors such as planning, project management, training, technology support, turnover rate, clinical workload, and communication were barriers to system implementation and use. Recommendations to improve the current system problems were discussed. Most nursing staff positively perceived the system's reduction of documentation and data access time, giving them more time with patients. System acceptance varied among doctors. System use also had positive impacts on timesaving, data quality, and clinical workflow. Critical Care Information Systems is crucial and has great potentials in enhancing and delivering critical care. However, the case study findings showed that the system faced complex challenges and was underutilised despite its potential. The role of socio-technical factors and their fit in realizing the potential of Critical Care Information Systems requires continuous, in-depth evaluation and stakeholder understanding and acknowledgement. The comprehensive and specific evaluation measures of the Human-Organisation-Technology Fit framework can flexibly evaluate Critical Care Information Systems. Copyright © 2015 Elsevier Ireland Ltd.

Summary Objective Does computerized provider order entry (CPOE) improve clinical, cost, and efficiency outcomes as quantified in shortened hospital length of stay (LOS)? Most prior studies were done in university settings with home-grown electronic records, and are now 20 years old. This study asked whether CPOE exerts a downward force on LOS in the current era of HITECH incentives, using a vendor product in a community hospital. Methods The methodology retrospectively evaluated correlation between CPOE and LOS on a perpatient, per-visit basis over 22 consecutive quarters, organized by discipline. All orders from all areas were eligible, except verbals, and medication orders in the emergency department which were not available via CPOE. These results were compared with quarterly case mix indices organized by discipline. Correlational and regression analyses were cross-checked to ensure validity of R-square coefficients, and data were smoothed for ease of display. Standard models were used to calculate the inflection point. Results Gains in CPOE adoption occurred iteratively house-wide, and in each discipline. LOS decreased in a sigmoid shaped curve. The inflection point shows that once CPOE adoption approaches 60%, further lowering of LOS accelerates. Overall there was a 20.2% reduction in LOS correlated with adoption of CPOE. Case mix index increased during the study period showing that reductions in LOS occurred despite increased patient complexity and resource utilization. Conclusions There was a 20.2% reduction in LOS correlated with rising adoption of CPOE. CPOE contributes to improved clinical, cost, and efficiency outcomes as quantified in reduced LOS, over and above other processes introduced to lower LOS. CPOE enabled a reduction in LOS despite an increase in the case mix index during the time frame of this study. PMID:25298809

The current study examined interactions among genetic influences and children's early environments on the development of externalizing behaviors from 18 months to 6 years of age. Participants included 233 families linked through adoption (birth parents and adoptive families). Genetic influences were assessed by birth parent temperamental regulation. Early environments included both family (overreactive parenting) and out-of-home factors (center-based Early Care and Education; ECE). Overreactive parenting predicted more child externalizing behaviors. Attending center-based ECE was associated with increasing externalizing behaviors only for children with genetic liability for dysregulation. Additionally, children who were at risk for externalizing behaviors due to both genetic variability and exposure to center-based ECE were more sensitive to the effects of overreactive parenting on externalizing behavior than other children.

Strategies aimed at stimulating the immune system against cancer have signaled a new era for designing new effective therapies for patients. Recent breakthroughs in adoptive cellular therapy and in using checkpoint inhibitors for some patients have renewed much enthusiasm in this field. However, it has become apparent that tumors can use a multitude of inhibitory networks to effectively reduce antitumor immunity. This review discusses our current knowledge of these immune suppressive mechanisms used by tumors and describes potential new strategies that may counteract this problem resulting in significantly increasing therapeutic outcomes of adoptive immunotherapy in a higher proportion of patients.

Educating women about congenital cytomegalovirus: assessment of health education materials through a web-based survey.

Congenital cytomegalovirus (CMV) is the most common congenital infection in the U.S. and can result in permanent disabilities, such as hearing and vision loss, intellectual disability, and psychomotor and language impairments. Women can adopt prevention behaviors in an attempt to reduce their exposure to CMV. Currently, few women are familiar with CMV. To increase awareness of CMV, the Centers for Disease Control and Prevention (CDC) developed draft health education materials. The purpose of this study was to pilot test two health education materials to gauge their appeal and to determine if they increase knowledge about CMV and motivate audiences to seek additional information on CMV and adopt CMV prevention behaviors. African-American (n = 404) and Caucasian women (n = 405), who had a young child and were either pregnant or planning a pregnancy, were recruited to participate in a 15-minute web survey. Participants were randomly assigned to view one of two CMV health education materials, either a factsheet or video. Pre and post survey measures were used to assess changes in knowledge of CMV and motivation to adopt prevention behaviors. We also examined audience preferences regarding materials and motivation. CMV knowledge score increased significantly after presentation of either the video or factsheet (from 3.7 out of 10 to 9.1 out of 10, p <0.001). The average materials appeal score was high, with a mean of 3.6 on a four-point scale, indicating women responded very positively to both materials. Regression analyses indicated that appeal, message involvement (e.g., information seeking, discussing with others), post materials knowledge score, and viewing the video (vs. factsheet) were significantly positively associated with increased support for CMV prevention behaviors. Overall, we found that the health education materials improved women's knowledge of CMV and encouraged them to adopt prevention behaviors. Given the low awareness levels among women currently, these findings suggest that appropriate education materials have the potential to greatly increase knowledge of CMV. As women become more knowledgeable about CMV and transmission routes, we expect they will be more likely to adopt prevention behaviors, thereby reducing their risk of CMV infection.

Health and fitness applications (apps) are one of the major app categories in the current mobile app market. Few studies have examined this area from the users' perspective. This study adopted the Extended Unified Theory of Acceptance and Use of Technology (UTAUT2) Model to examine the predictors of the users' intention to adopt health and fitness apps. A survey (n=317) was conducted with college-aged smartphone users at a Midwestern university in the United States. Performance expectancy, hedonic motivations, price value, and habit were significant predictors of users' intention of continued usage of health and fitness apps. However, effort expectancy, social influence, and facilitating conditions were not found to predict users' intention of continued usage of health and fitness apps. This study extends the UTATU2 Model to the mobile apps domain and provides health professions, app designers, and marketers with the insights of user experience in terms of continuously using health and fitness apps.

The Subsonic Fixed Wing Project of NASA's Fundamental Aeronautics Program has adopted a noise reduction goal for new, subsonic, single-aisle, civil aircraft expected to replace current 737 and A320 airplanes. These so-called 'N+1' aircraft - designated in NASA vernacular as such since they will follow the current, in-service, 'N' airplanes - are hoped to achieve certification noise goal levels of 32 cumulative EPNdB under current Stage 4 noise regulations. A notional, N+1, single-aisle, twinjet transport with ultrahigh bypass ratio turbofan engines is analyzed in this study using NASA software and methods. Several advanced noise-reduction technologies are analytically applied to the propulsion system and airframe. Certification noise levels are predicted and compared with the NASA goal.

On the dual equivalence of the self-dual and topologically massive /B∧F models coupled to dynamical fermionic matter

We study the equivalence between the /B∧F self-dual (SDB∧F) and the /B∧F topologically massive (TMB∧F) models including the coupling to dynamical, U(1) charged fermionic matter. This is done through an iterative procedure of gauge embedding that produces the dual mapping. In the interactive cases, the minimal coupling adopted for both vector and tensor fields in the self-dual representation is transformed into a non-minimal magnetic like coupling in the topologically massive representation but with the currents swapped. It is known that to establish this equivalence a current-current interaction term is needed to render the matter sector unchanged. We show that both terms arise naturally from the embedding procedure.

Previous research has demonstrated that trainees can be taught (via explicit verbal instruction) to adopt the gaze strategies of expert laparoscopic surgeons. The current study examined a software template designed to guide trainees to adopt expert gaze control strategies passively, without being provided with explicit instructions. We examined 27 novices (who had no laparoscopic training) performing 50 learning trials of a laparoscopic training task in either a discovery-learning (DL) group or a gaze-training (GT) group while wearing an eye tracker to assess gaze control. The GT group performed trials using a surgery-training template (STT); software that is designed to guide expert-like gaze strategies by highlighting the key locations on the monitor screen. The DL group had a normal, unrestricted view of the scene on the monitor screen. Both groups then took part in a nondelayed retention test (to assess learning) and a stress test (under social evaluative threat) with a normal view of the scene. The STT was successful in guiding the GT group to adopt an expert-like gaze strategy (displaying more target-locking fixations). Adopting expert gaze strategies led to an improvement in performance for the GT group, which outperformed the DL group in both retention and stress tests (faster completion time and fewer errors). The STT is a practical and cost-effective training interface that automatically promotes an optimal gaze strategy. Trainees who are trained to adopt the efficient target-locking gaze strategy of experts gain a performance advantage over trainees left to discover their own strategies for task completion.

To better understand the relationship between perceived risk of falling and awareness and adoption of four specific precautions that older adults have taken to reduce this risk. Cross-sectional. Data were collected in in-person interviews conducted in the homes of study participants. Interviews conducted between March 2011 and September 2013 and lasted an average of 60-90 minutes. A stratified sampling strategy designed to enroll an equal number of homebound and nonhomebound participants was used. All participants (N = 164) were recruited from central North Carolina. Participants were asked about 1-year fall history, perceived risk of falling, restriction of activities because of fear of falling, awareness of four recommended fall prevention behaviors (exercise, annual medication review, bathroom grab bars, safe footwear), and current practice of these behaviors. In bivariate analyses, individuals who were aware of two behaviors recommended to reduce the risk of falling (exercise, use of safe footwear) and had adopted these behaviors perceived their risk of falling as lower than individuals who were aware of the recommended behaviors but had not adopted them. Moreover, in multivariate analyses, individuals who did not know that exercise is recommended to reduce the risk of falling perceived their risk of falling as lower than those who were aware of this recommendation and had adopted it. Individuals were least likely to be aware that medication reviews and exercise are recommended to reduce fall risk. Awareness of behaviors recommended to reduce fall risk appears necessary for adoption of these behaviors to reduce perceived risk. Fall-prevention campaigns should emphasize behaviors where awareness is low. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Background Personal health records (PHRs) offer a tremendous opportunity to generate consumer support in pursing the triple aim of reducing costs, increasing access, and improving care quality. Moreover, surveys in the United States indicate that consumers want Web-based access to their medical records. However, concerns that consumers’ low health information literacy levels and physicians’ resistance to sharing notes will limit PHRs’ utility to a relatively small portion of the population have reduced both the product innovation and policy imperatives. Objective The purpose of our study was 3-fold: first, to report on US consumers’ current level of PHR activity; second, to describe the roles of imitation and innovation influence factors in determining PHR adoption rates; and third, to forecast future PHR diffusion uptake among US consumers under 3 scenarios. Methods We used secondary data from the Health Information National Trends Survey (HINTS) of US citizens for the survey years 2008, 2011, and 2013. Applying technology diffusion theory and Bass modeling, we evaluated 3 future PHR adoption scenarios by varying the introduction dates. Results All models displayed the characteristic diffusion S-curve indicating that the PHR technology is likely to achieve significant market penetration ahead of meaningful use goals. The best-performing model indicates that PHR adoption will exceed 75% by 2020. Therefore, the meaningful use program targets for PHR adoption are below the rates likely to occur without an intervention. Conclusions The promise of improved care quality and cost savings through better consumer engagement prompted the US Institute of Medicine to call for universal PHR adoption in 1999. The PHR products available as of 2014 are likely to meet and exceed meaningful use stage 3 targets before 2020 without any incentive. Therefore, more ambitious uptake and functionality availability should be incorporated into future goals. PMID:27030105

Adoption of molecular-based water quality tests has been limited despite their advantage over traditional culture-based tests. A better understanding of the factors affecting adoption of these tests is needed for effective implementation. The Consolidated Framework for Implementation Research (CFIR) was used to analyze interviews with policy makers, watershed managers and laboratory managers in British Columbia (BC), Canada about their perceptions of molecular water tests currently under development in order to assess readiness for adoption and identify factors that may impact implementation. Many of the CFIR constructs were addressed by study participants, thus confirming their validity in the water-testing context. Other constructs were not mentioned, which suggests that awareness about these constructs need to be increased to ensure that they are incorporated into implementation strategies. In general, there was much enthusiasm for the new tests, which were seen to provide valuable information that could enable improved management of watersheds and treatment of source water. However, prior to adopting the tests, stakeholders would require evidence supporting the tests' validity and reliability, would need to assess the complexity of introducing the tests into laboratories and water sampling processes, and would require support interpreting the test results. Even if all the aforementioned issues are satisfactorily addressed, the tests may not be adopted unless regulations and policies were changed to allow the use of these test results to inform decision making. The results support that implementation of new technologies, such as these water quality tests, need to address potential barriers that could hinder uptake despite the advantages of the new product.

With the rising concern about climate change, there has been an increased public awareness that has resulted in new government policies to support scientific research for mitigating these problems. Malaysia is among the major energy-intense countries and is under an excessive burden to advance its energy efficiency and to also work towards the reduction of its carbon emission. Plug-in hybrid electric vehicles (PHEVs) have the potential to lessen the carbon emission and gasoline consumption in order to alleviate environmental problems. Most of the energy problems linked to the increasing transportation pollution are now being reduced with the solution of the adoption of PHEVs. PHEVs are seen as a solution to cut carbon emission, which prevents environmental damages. Furthermore, PHEVs' driving range and performance can be comparable to the other hybrid vehicles as well as the conventional IC engines that have gasoline and diesel tanks. Thus, many efforts are being initiated to promote the use of PHEVs as an innovative and affordable transportation system. In order to achieve making the consumers aware of the adoption of PHEVs, we used a model which is based on the extended theory of planned behavior (TPB). This review is based on the factors affecting the adoption of PHEVs among Malaysian consumers. The model takes into account the ten key features that influence the adoption of PHEVs, such as environmental concern, personal norm, attitude, vehicle ownership costs, driving range, charging time, intention, subjective norm, perceived behavioral control, and personal norm. All these constructs are drivers towards the adoption of PHEVs. These factors affect the relationship between the adoption of PHEVs and how consumers intend to protect the environment. This review is based on improving how the "attitude-action" gap is understood as it is an important element for further studies on PHEVs. The aim of the research is to come up with a framework that examines how to modify the consumer's environmental concerns in acquiring PHEVs. This will pave the way for more academic research and future works that can emphasize how to obtain empirical results. The authors' recommendation is that, before a consumer's behavior is assessed and considered, an observation of the current technology is needed with methods and knowledge of the existing technology adoption aspect.

Estimating the cost of compensating victims of medical negligence.

PubMed Central

Fenn, P.; Hermans, D.; Dingwall, R.

1994-01-01

The current system in Britain for compensating victims of medical injury depends on an assessment of negligence. Despite the sporadic pressure on the government to adopt a "no fault" approach, such as exists in Sweden, the negligence system will probably remain for the immediate future. The cost of this system was estimated to be 52.3m pounds for England 1990-1. The problem for the future, however, is one of forecasting accuracy at provider level: too high a guess and current patient care will suffer; too low a guess and future patient care will suffer. The introduction of a mutual insurance scheme may not resolve these difficulties, as someone will have to set the rates. Moreover, the figures indicate that if a no fault scheme was introduced the cost might be four times that of the current system, depending on the type of scheme adopted. PMID:8081145

Accounting for biodiversity in the dairy industry.

PubMed

Sizemore, Grant C

2015-05-15

Biodiversity is an essential part of properly functioning ecosystems, yet the loss of biodiversity currently occurs at rates unparalleled in the modern era. One of the major causes of this phenomenon is habitat loss and modification as a result of intensified agricultural practices. This paper provides a starting point for considering biodiversity within dairy production, and, although focusing primarily on the United States, findings are applicable broadly. Biodiversity definitions and assessments (e.g., indicators, tools) are proposed and reviewed. Although no single indicator or tool currently meets all the needs of comprehensive assessment, many sustainable practices are readily adoptable as ways to conserve and promote biodiversity. These practices, as well as potential funding opportunities are identified. Given the state of uncertainty in addressing the complex nature of biodiversity assessments, the adoption of generally sustainable environmental practices may be the best currently available option for protecting biodiversity on dairy lands.

We derive structure functions for the quasielastic production of octet baryons in νn and νp interactions and study the polarization of τ leptons produced in the ΔY=0 reactions. Possible impact of the charged second-class currents is investigated by adopting a simple phenomenological parametrization for the nonstandard scalar and tensor nucleon form factors. Our choice of the unknown parameters is made to satisfy the limits obtained in the (anti)neutrino scattering experiments and rigid restrictions derived from the nuclear structure studies.

The implementation of problem-based learning: changing pedagogy in nurse education.

PubMed

Creedy, D; Hand, B

1994-10-01

Problem-based learning (PBL) employs approaches to teaching and learning in nurse education that develop meaningful links between theory and practice. The adoption of such approaches, however, may require changes in pedagogical beliefs and practices which reflect a student-centred approach to teaching and learning. This paper focuses on a group of volunteer nurse educators (n = 14) who attended a 7-month professional development programme centred on introducing pedagogical changes when adopting PBL. From this group, three nurse educators participated in an in-depth study which aimed to examine the processes of conceptual change associated with adopting PBL as part of alternative teaching strategies. These three participants held common concerns about the changes required to their current teaching practices when moving to a new pedagogical approach. On completion of the programme, varying degrees of change in existing instructional practices were evident. This change was found to result from engaging educators in reflection about practice, providing opportunities to implement the new approaches on a trial basis, and providing feedback and support throughout the change process.

[Revision of the TNM Stage Grouping in the Forthcoming Eighth Edition of the TNM Classification for Lung Cancer].

Ye, Bo; Zhao, Heng

2016-06-20

The currently adopted staging system for lung cancer is the seventh edition of the TNM staging edited by Union for International Cancer Control (UICC) in January, 2009. In recent years, with the advances of techniques in lung cancer diagnosis and the treatment trends towards precision treatment modalities such as individualized therapy and molecular targeted therapy, the survival and prognosis of lung cancer has been significantly improved. The old staging standard is difficult to satisfy the currentrapidly developing clinical needs. Therefore, the International Lung Cancer Research Society (International Association for the Study of Lung Cancer, IASLC) updated the stage of lung cancer in 2015, and the forthcoming eighth edition of the TNM Classification for Lung Cancer, which will be formally adopted in Jan. 2017, has been published in Journal of Thoracic Oncology. The new staging system has adopted 35 databases from 16 countries, including 94,708 cases treated between 1999 and 2010. The advantages of the new staging lies in its higher prognosis prediction and clinical guidance value.

Diffusion of innovation theory for clinical change.

PubMed

Sanson-Fisher, Robert W

2004-03-15

Maximising the adoption of evidence-based practice has been argued to be a major factor in determining healthcare outcomes. However, there are gaps between evidence-based recommendations and current care. Bridging the evidence gap will not be achieved simply by informing clinicians about the evidence. One theoretical approach to understanding how change may be achieved is Rogers' diffusion model. He argues that certain characteristics of the innovation itself may facilitate its adoption. Other factors influencing acceptance include promotion by influential role models, the degree of complexity of the change, compatibility with existing values and needs, and the ability to test and modify the new procedure before adopting it. The diffusion model may provide valuable insights into why some practices change and others do not, as well as guiding those who try to effect adoption of best-evidence practice.

Trans-disciplinary community groups: an initiative for improving healthcare.

PubMed

Sideras, James Demetri

2016-01-01

In the context of budget constraints and the current quality crisis facing UK healthcare, the purpose of this paper is to examine the use of trans-disciplinary community groups (TCG)--an innovative and inexpensive initiative for improving patient care. Using an action research study, TCG was implemented within a private healthcare firm for vulnerable adults. Qualitative data were gathered over 12 months from 33 participants using depth interviews and focus groups. TCG led to improved patient activities and increased patient decision-making and confidence in self-advocacy. Key prerequisites were top management commitment, democratic leadership and employee empowerment. However, staff nurses resisted TCG because they were inclined to using managerial control and their own independent clinical judgements. Whilst the findings from this study should not be generalized across all healthcare sectors, its results could be replicated in contexts where there is wide commitment to TCG and where managers adopt a democratic style of leadership. Researchers could take this study further by exploring the applicability of TCG in public healthcare organizations or other multi-disciplinary service contexts. The findings of this research paper provide policy makers and healthcare managers with practical insights on TCG and the factors that are likely to obstruct and facilitate its implementation. Adopting TCG could enable healthcare managers to ameliorate their services with little or no extra cost, which is especially important in a budget constraint context and the current quality crisis facing UK healthcare.

Therapeutic Use of Prebiotics, Probiotics, and Postbiotics to Prevent Necrotizing Enterocolitis: What is the Current Evidence?

Patel, Ravi Mangal; Denning, Patricia Wei

2013-01-01

Synopsis Necrotizing enterocolitis (NEC) is a leading cause of neonatal morbidity and mortality and preventative therapies that are both effective and safe are urgently needed. Current evidence from therapeutic trials suggests that probiotics are effective in decreasing NEC in preterm infants and probiotics are currently the most promising therapy on the horizon for this devastating disease. However, concerns regarding safety and optimal dosing have limited the widespread adoption of routine clinical use of probiotics in preterm infants. In addition, prebiotics and postbiotics may be potential alternatives or adjunctive therapies to the administration of live microorganisms, although studies demonstrating their clinical efficacy in preventing NEC are lacking. This review summarizes the current evidence regarding the use of probiotics, prebiotics and postbiotics in the preterm infant, including its therapeutic role in preventing NEC. PMID:23415261

2016-04-01

In many families, siblings play important roles in shaping each other's outcomes and experiences across development. In adoptive families, siblings may affect adoptees' feelings about adoption and birth family contact. Among "target adoptees" (i.e., 1 participating adopted individual within adoptive families) with siblings who may have also been adopted or the biological children of the adoptive parents, we examined how adoption experiences and individual adjustment from adolescence into emerging adulthood were associated with sibling relationship dynamics. We present 3 studies using longitudinal, mixed method data within the same overarching sample of adoptive families. Study 1 was a follow-up to Berge et al.'s (2006) study of adolescent adoptees and their adopted siblings with birth family contact; we found evidence of changes in the status of contact collectively experienced by 26 adopted sibling pairs when target adoptees were emerging adults. In Study 2, we found that target adoptees (n = 91) with siblings (adopted or not) who were more involved with target adoptees' birth family contact demonstrated more favorable behavioral outcomes than target adoptees who had uninvolved siblings. Finally in Study 3, for target adoptees with siblings who were also adopted (n = 51), results showed that target adoptees felt more positively about their own adoption when siblings expressed similar positive feelings about individual adoption experiences. Implications of our findings are discussed in terms of the enduring contributions of sibling relationships from childhood into adulthood and the unique ways in which adoptive siblings are important in shaping one another's experiences of adoption.

Estimates of associated outdoor particulate matter health risk and costs reductions from alternative building, ventilation and filtration scenarios.

PubMed

Sultan, Zuraimi M

2007-05-01

Although many studies have reported calculations of outdoor particulate matter (PM) associated externalities using ambient data, there is little information on the role buildings, their ventilation and filtration play. This study provides the framework to evaluate the health risk and cost reduction of building, ventilation and filtration strategies from outdoor PM pollution on a nationwide level and applied it to a case study in Singapore. Combining Indoor Air Quality (IAQ) and time weighted exposure models, with established concentration-response functions and monetary valuation methods, mortality and morbidity effects of outdoor PM on the population of Singapore under different building, ventilation and filtration strategies were estimated. Different interventions were made to compare the effects from the current building conditions. The findings demonstrate that building protection effect reduced approximately half the attributable health cases amounting to US$17.7 billion due to PM pollution when compared to levels computed using outdoor data alone. For residential buildings, nationwide adoption of natural ventilation from current state is associated with 28% higher cases of mortality and 13 to 38% higher cases for different morbidities, amounting to US$6.7 billion. The incurred cost is negligible compared to energy costs of air-conditioning. However, nationwide adoption of closed residence and air-conditioning are associated with outcomes including fewer mortality (10 and 6% respectively), fewer morbidities (8 and 4% respectively) and economic savings of US$1.5 and 0.9 billion respectively. The related savings were about a factor of 9 the energy cost for air-conditioning. Nationwide adoption of mechanical ventilation and filtration from current natural ventilation in schools is associated with fewer asthma hospital admissions and exacerbations; although the economic impact is not substantial. Enhanced workplace filtration reduces the mortality and morbidity cases by 14 and 13% respectively amounting to savings of up to US$2.4 billion. The huge costs savings are comparable to the average worker salary and insignificant to energy, installation and rental cost. Despite uncertainty about accurate benefits, this study shows that health and economic gain via different building, ventilation and filtration designs in minimizing ingress of outdoor PM applied to a nationwide scale can be very large. Importantly, the results suggest that PM associated externalities and legislative efforts should not only focus on ambient PM reduction policies but also include building-informed decisions.

To characterize early adoption of a novel multitarget stool DNA (MT-sDNA) screening test for colorectal cancer (CRC) screening and to test the hypothesis that adoption differs by demographic characteristics and prior CRC screening behavior and proceeds predictably over time. We used the Rochester Epidemiology Project research infrastructure to assess the use of the MT-sDNA screening test in adults aged 50 to 75 years living in Olmsted County, Minnesota, in 2014 and identified 27,147 individuals eligible or due for screening colonoscopy from November 1, 2014, through November 30, 2015. We used electronic Current Procedure Terminology and Health Care Common Procedure codes to evaluate early adoption of the MT-sDNA screening test in this population and to test whether early adoption varies by age, sex, race, and prior CRC screening behavior. Overall, 2193 (8.1%) and 974 (3.6%) individuals were screened by colonoscopy and MT-sDNA, respectively. Age, sex, race, and prior CRC screening behavior were significantly and independently associated with MT-sDNA screening use compared with colonoscopy use after adjustment for all other variables (P<.05 for all). The rates of adoption of MT-sDNA screening increased over time and were highest in those aged 50 to 54 years, women, whites, and those who had a history of screening. The use of the MT-sDNA screening test varied predictably by insurance coverage. The rates of colonoscopy decreased over time, whereas overall CRC screening rates remained steady. The results of the present study are generally consistent with predictions derived from prior research and the diffusion of innovation framework, pointing to increasing use of the new screening test over time and early adoption by younger patients, women, whites, and those with prior CRC screening.

2017-05-01

The first aim of the current study was to examine the latent structure of attachment states of mind as assessed by the Adult Attachment Interview (AAI) among three groups of parents of children at risk for insecure attachments: parents who adopted internationally (N = 147), foster parents (N = 300), and parents living in poverty and involved with Child Protective Services (CPS; N = 284). Confirmatory factor analysis indicated the state of mind rating scales loaded on two factors reflecting adults' preoccupied and dismissing states of mind. Taxometric analyses indicated the variation in adults' preoccupied states of mind was more consistent with a dimensional than a categorical model, whereas results for dismissing states of mind were indeterminate. The second aim was to examine the degree to which the attachment states of mind of internationally adoptive and foster parents differ from those of poverty/CPS-referred parents and low-risk parents. After controlling for parental age, sex, ethnicity, and socioeconomic status, (a) internationally adoptive parents had lower scores on the dismissing dimension than the sample of community parents described by Haltigan, Leerkes, Supple, and Calkins (2014); (b) foster parents did not differ from community parents on either the dismissing or the preoccupied AAI dimension; and (c) both internationally adoptive and foster parents had lower scores on the preoccupied dimension than poverty/CPS-referred parents. Analyses using the traditional AAI categories provided convergent evidence that (a) internationally adoptive parents were more likely to be classified as having an autonomous state of mind than low-risk North American mothers based on Bakermans-Kranenburg and van IJzendoorn's (2009) meta-analytic estimates, (b) the rates of autonomous states of mind did not differ between foster and low-risk parents, and (c) both internationally adoptive and foster parents were less likely to be classified as having a preoccupied state of mind than poverty/CPS-referred parents.

CMV-Specific CD8 T Cell Differentiation and Localization: Implications for Adoptive Therapies.

PubMed

Smith, Corinne J; Quinn, Michael; Snyder, Christopher M

2016-01-01

Human cytomegalovirus (HCMV) is a ubiquitous virus that causes chronic infection and, thus, is one of the most common infectious complications of immune suppression. Adoptive transfer of HCMV-specific T cells has emerged as an effective method to reduce the risk for HCMV infection and/or reactivation by restoring immunity in transplant recipients. However, the CMV-specific CD8 + T cell response is comprised of a heterogenous mixture of subsets with distinct functions and localization, and it is not clear if current adoptive immunotherapy protocols can reconstitute the full spectrum of CD8 + T cell immunity. The aim of this review is to briefly summarize the role of these T cell subsets in CMV immunity and to describe how current adoptive immunotherapy practices might affect their reconstitution in patients. The bulk of the CMV-specific CD8 + T cell population is made up of terminally differentiated effector T cells with immediate effector function and a short life span. Self-renewing memory T cells within the CMV-specific population retain the capacity to expand and differentiate upon challenge and are important for the long-term persistence of the CD8 + T cell response. Finally, mucosal organs, which are frequent sites of CMV reactivation, are primarily inhabited by tissue-resident memory T cells, which do not recirculate. Future work on adoptive transfer strategies may need to focus on striking a balance between the formation of these subsets to ensure the development of long lasting and protective immune responses that can access the organs affected by CMV disease.

What contact arrangements are established between providers and recipients of embryos using Snowflakes® Embryo Adoption Program? Contact arrangements varied considerably and were generally positively described, although some challenges were acknowledged. Reproductive technologies create new and diverse family forms, and the ways in which families created by embryo adoption are negotiated in practice have not been extensively investigated. This exploratory, mixed-methods study had two phases: (i) an online survey (open May-September 2013) and (ii) qualitative semi-structured interviews by email (conducted between 2014 and 2015), exploring participants' experiences of contact with their embryo provider or recipient. Phase I included 17 providers (14 women and 3 men) and 28 recipients (27 women and 1 man). Phase II included 8 providers (5 women and 3 men) and 12 recipients (10 women and 2 men). All participants, except one, were located in the US. This study illustrates how embryo adoption in the US, as a form of conditional donation, can operate and how the participants define and negotiate these emerging relationships. All families were open with their children about how they were conceived and early contact between recipients and providers (frequently before birth) was valued. On the whole, participants were happy with the amount and type of contact they had, and where the current contact did not involve the children, it was seen as a way of keeping the channels open for future contact when the children were older. Participants often portrayed the opportunities for contact as being in the best interests of the child. The study participants are a particular group who had chosen to either receive or give their embryos via a conditional embryo adoption agency in the US and had established contact. Therefore, this is not a representative sample of those who provide or receive embryos for family building. This embryo adoption model clearly fulfils a need; some people want to use a conditional embryo donation programme such as Snowflakes®. Some form of 'ongoing support mechanism' such as counselling could be useful for those negotiating the complex sets of new kinship patterns and balancing these relationships with their children's welfare. The authors have no conflict of interest to declare. Snowflakes is a commercial adoption agency and the authors have no relation to the organization, other than requesting that they participate in this research project. N/A. © The Author 2017.

1998-07-01

A uniformly adopted color standards infrastructure has a dramatic impact on any color imaging industry and technology. This presentation begins by framing the current color standards situation in a historical context. A series of similar appearing infrastructure adoptions in color publishing during the last fifty years are reviewed and compared to the current events. This historical review is followed by brief technical, business and marketing reviews of two of the more popular recent color standards proposals, sRGB and ICC, along with their operating system implementations in the Microsoft and Apple operating systems. The paper concludes with a summary of Hewlett- Packard Company's and Microsoft's proposed future direction.

One of the main goals of brain-machine interface (BMI) research is to restore function to people with paralysis. Currently, multiple BMI design features are being investigated, based on various input modalities (externally applied and surgically implantable sensors) and output modalities (e.g. control of computer systems, prosthetic arms, and functional electrical stimulation systems). While these technologies may eventually provide some level of benefit, they each carry associated burdens for end-users. We sought to assess the attitudes of people with paralysis toward using various technologies to achieve particular benefits, given the burdens currently associated with the use of each system. We designed and distributed a technology survey to determine the level of benefit necessary for people with tetraplegia due to spinal cord injury to consider using different technologies, given the burdens currently associated with them. The survey queried user preferences for 8 BMI technologies including electroencephalography, electrocorticography, and intracortical microelectrode arrays, as well as a commercially available eye tracking system for comparison. Participants used a 5-point scale to rate their likelihood to adopt these technologies for 13 potential control capabilities. Survey respondents were most likely to adopt BMI technology to restore some of their natural upper extremity function, including restoration of hand grasp and/or some degree of natural arm movement. High speed typing and control of a fast robot arm were also of interest to this population. Surgically implanted wireless technologies were twice as 'likely' to be adopted as their wired equivalents. Assessing end-user preferences is an essential prerequisite to the design and implementation of any assistive technology. The results of this survey suggest that people with tetraplegia would adopt an unobtrusive, autonomous BMI system for both restoration of upper extremity function and control of external devices such as communication interfaces.

Design and Experimental Study of a Current Transformer with a Stacked PCB Based on B-Dot.

An electronic current transformer with a B-dot sensor is proposed in this study. The B-dot sensor can realize the current measurement of the transmission line in a non-contact way in accordance with the principle of magnetic field coupling. The multiple electrodes series-opposing structure is applied together with differential input structures and active integrating circuits, which can allow the sensor to operate in differential mode. Maxwell software is adopted to model and simulate the sensor. Optimization of the sensor structural parameters is conducted through finite-element simulation. A test platform is built to conduct the steady-state characteristic, on-off operation, and linearity tests for the designed current transformer under the power-frequency current. As shown by the test results, in contrast with traditional electromagnetic CT, the designed current transformer can achieve high accuracy and good phase-frequency; its linearity is also very good at different distances from the wire. The proposed current transformer provides a new method for electricity larceny prevention and on-line monitoring of the power grid in an electric system, thereby satisfying the development demands of the smart power grid.

The effect of adopting new storage methods for extending product validity periods on manufacturers expected inventory costs.

PubMed

Chen, Po-Yu

2014-01-01

The validness of the expiration dates (validity period) that manufacturers provide on food product labels is a crucial food safety problem. Governments must study how to use their authority by implementing fair awards and punishments to prompt manufacturers into adopting rigorous considerations, such as the effect of adopting new storage methods for extending product validity periods on expected costs. Assuming that a manufacturer sells fresh food or drugs, this manufacturer must respond to current stochastic demands at each unit of time to determine the purchase amount of products for sale. If this decision maker is capable and an opportunity arises, new packaging methods (e.g., aluminum foil packaging, vacuum packaging, high-temperature sterilization after glass packaging, or packaging with various degrees of dryness) or storage methods (i.e., adding desiccants or various antioxidants) can be chosen to extend the validity periods of products. To minimize expected costs, this decision maker must be aware of the processing costs of new storage methods, inventory standards, inventory cycle lengths, and changes in relationships between factors such as stochastic demand functions in a cycle. Based on these changes in relationships, this study established a mathematical model as a basis for discussing the aforementioned topics.

This research focused on accelerating solar photovoltaic (PV) diffusion by collecting new market data and developing predictive modeling frameworks to test and refine understandings of household level motivations for adopting solar. Three different household-level surveys were fielded: one for households who had installed PV on their current home or had signed a contract to do so (the Adopter survey), one for households that had seriously considered PV but had not installed it (the Considerer survey), and one for the general population who did not have PV on their current home (the general population survey or GPS). Survey respondents were from four U.S. states: New Jersey, New York, Arizona, and California. Details of recruiting and sampling are documented below. Research projects on residential PV adoption often collect data only from PV adopters or from the general population. One of the innovations of this project was the three-pronged household survey data collection. By collecting similar data from three fairly different "statuses" with respect to adoption, the surveys provide a basis for understanding how those who do not have rooftop PV differ from those who have, for how and why people do (or don't) transition from not having to having rooftop PV on their home, and for understanding the characteristics and viewpoints of households who have scarcely, or not at all, entered the "PV consideration" track. All three surveys covered single-family owner-occupied households in each of the four target states used in the project -- Arizona, California, New Jersey, and New York - allowing a comparative approach to understanding how the factors that affect PV adoption vary by geography and policy conditions. The General Population and Considerer surveys provide a basis for understanding opinions about and interest in solar, and how these relate to household demographics and other conditions. Paired with the Adopter survey, they also provide data for understanding how those who do not have rooftop PV differ from those who have, and for how and why people do (or don't) transition from not having to having rooftop PV on their home. The Adopter survey questions were designed to capture a broad range of information on what motivates and impedes households to install rooftop PV, as well as the details and timing of the decision and installation. Survey instrument development drew from existing PV adoption survey instruments, PV adoption literature, and research team experience, as well as from past work on household interest in energy efficiency, environmental attitudes, purchasing tendencies, and related knowledge. Early interviews and discussions with installers and others in the PV industry were also taken into consideration.

Phytosanitary irradiation of fresh tropical commodities in Hawaii: Generic treatments, commercial adoption, and current issues

Follett, Peter A.; Weinert, Eric D.

2012-08-01

Hawaii is a pioneer in the use of phytosanitary irradiation. The commercial X-ray irradiation facility, Hawaii Pride LLC, has been shipping papaya and other tropical fruits and vegetables to the United States mainland using irradiation for 11 years. Irradiation is an approved treatment to control quarantine pests in 17 fruits and 7 vegetables for export from Hawaii to the US mainland. Hawaiian purple sweet potato is the highest volume product with annual exports of more than 12 million lbs (5500 t). The advent of generic radiation treatments for tephritid fruit flies (150 Gy) and other insects (400 Gy) will accelerate commodity export approvals and facilitate worldwide adoption. Lowering doses for specific pests and commodities can lower treatment costs and increase capacity owing to shorter treatment times, and will minimize any quality problems. Current impediments to wider adoption include the 1 kGy limit for fresh horticultural products, the labeling requirement, and non-acceptance of phytosanitary irradiation in Japan, the European Union, and elsewhere. Irradiation has potential as a treatment for unregulated imports to prevent new pest incursions.

To better understand the nature of sibling relationships among children in foster or adoptive placement and the challenges and processes involved in maintaining these relationships, we conducted an exploratory analysis of data collected from semi-structured interviews with caregivers of 14 foster and adopted children in San Diego County. We identified three patterns of placement histories and living situations which appeared to impact the degree of contact maintained with siblings: (1) children who had never lived together and were not currently placed together; (2) children who at some point lived with or were placed together with their siblings, but were now separated from them; and (3) children who had lived with their siblings all their life and were placed together with at least some of their siblings at the time of the interview. Children's current living situations and placement histories, caregivers' experiences and perceptions of feasibility and desirability of sibling contact, and the sibling relationship itself are primary determinants in the development and maintenance of contact between siblings. Implications for child welfare policy and practice are discussed.

What’s in a Name? Effect of Breed Perceptions & Labeling on Attractiveness, Adoptions & Length of Stay for Pit-Bull-Type Dogs

2016-01-01

Previous research has indicated that certain breeds of dogs stay longer in shelters than others. However, exactly how breed perception and identification influences potential adopters' decisions remains unclear. Current dog breed identification practices in animal shelters are often based upon information supplied by the relinquishing owner, or staff determination based on the dog's phenotype. However, discrepancies have been found between breed identification as typically assessed by welfare agencies and the outcome of DNA analysis. In Study 1, the perceived behavioral and adoptability characteristics of a pit-bull-type dog were compared with those of a Labrador Retriever and Border Collie. How the addition of a human handler influenced those perceptions was also assessed. In Study 2, lengths of stay and perceived attractiveness of dogs that were labeled as pit bull breeds were compared to dogs that were phenotypically similar but were labeled as another breed at an animal shelter. The latter dogs were called "lookalikes." In Study 3, we compared perceived attractiveness in video recordings of pit-bull-type dogs and lookalikes with and without breed labels. Lastly, data from an animal shelter that ceased applying breed labeling on kennels were analyzed, and lengths of stay and outcomes for all dog breeds, including pit bulls, before and after the change in labeling practice were compared. In total, these findings suggest that breed labeling influences potential adopters' perceptions and decision-making. Given the inherent complexity of breed assignment based on morphology coupled with negative breed perceptions, removing breed labels is a relatively low-cost strategy that will likely improve outcomes for dogs in animal shelters.

Laboratory animal science in China: current status and potential for adoption of Three R alternatives.

PubMed

Kong, Qi; Qin, Chuan

2010-03-01

This paper aims to describe the development of laboratory animal science in China on the basis of historical evidence and recent national survey data, and to identify the problems facing the adoption of Three R alternatives. The authors undertook a national survey in 2006, by means of a questionnaire sent to 31 provinces, municipalities and autonomous regions, and also compared data from a variety of sources, including several national surveys and published papers. Laboratory animal science in China has developed rapidly over the past 30 years, as a result of a combination of economic, governmental and societal forces. More than 100,000 people work in the field of laboratory animal science, in 2,000 laboratory animal centres, institutes, universities, organisations, and companies. During the year of our survey, more than 19 million laboratory animals were produced from 320 licensed production facilities. Approximately 16 million laboratory animals were used in animal experiments, in 1530 facilities licensed for their use. The scale of the market for the supply and use of laboratory animals is huge, and thus it is very important to improve the level of adoption of these alternatives, in education, research and testing. For China, this presents a significant economic and technological opportunity in the field of biosciences research. The concept of the Three Rs first appeared in China in the 1980s, when the scale of laboratory animal sciences was starting to increase. In the 1990s, the Three Rs concept became commonly accepted among laboratory animal scientists, and began to appear in government documents. In the first decade of the 21st century, the Three Rs principles have become increasingly applied in our day-to-day work. But further time is still needed to achieve the full application of the Three Rs principles, especially the adoption of Three R alternatives. This paper describes the achievements in China relating to laboratory animal science, the use of Three R alternatives, and animal welfare, and shows that there is currently great potential for the adoption of alternatives. The information will help scientists and organisations around the world to gain better insight into the current state of laboratory animal science in China, and hopefully, will enable them to give advice on how we can improve the adoption of Three R alternatives in our country. 2010 FRAME.

The electrode of a vanadium redox flow battery generally is a carbon fibre-based porous medium, in which important physicochemical processes occur. In this work, pore-scale simulations are performed to study complex multiphase flow and reactive transport in the electrode by using the lattice Boltzmann method (LBM). Four hundred fibrous electrodes with different fibre diameters and porosities are reconstructed. Both the permeability and diffusivity of the reconstructed electrodes are predicted and compared with empirical relationships in the literature. Reactive surface area of the electrodes is also evaluated and it is found that existing empirical relationship overestimates the reactive surface under lowermore » porosities. Further, a pore-scale electrochemical reaction model is developed to study the effects of fibre diameter and porosity on electrolyte flow, V II/V III transport, and electrochemical reaction at the electrolyte-fibre surface. Finally, evolution of bubble cluster generated by the side reaction is studied by adopting a LB multiphase flow model. Effects of porosity, fibre diameter, gas saturation and solid surface wettability on average bubble diameter and reduction of reactive surface area due to coverage of bubbles on solid surface are investigated in detail. It is found that gas coverage ratio is always lower than that adopted in the continuum model in the literature. Furthermore, the current pore-scale studies successfully reveal the complex multiphase flow and reactive transport processes in the electrode, and the simulation results can be further upscaled to improve the accuracy of the current continuum-scale models.« less

Pleural effusion is a common clinical manifestation with various causes. Current diagnostic and therapeutic methods have exhibited numerous limitations. By involving the analysis of dynamic changes in low molecular weight catabolites, metabolomics has been widely applied in various types of disease and have provided platforms to distinguish many novel biomarkers. However, to the best of our knowledge, there are few studies regarding the metabolic profiling for pleural effusion. In the current study, 58 pleural effusion samples were collected, among which 20 were malignant pleural effusions, 20 were tuberculous pleural effusions and 18 were transudative pleural effusions. The small molecule metabolite spectrums were obtained by adopting 1H nuclear magnetic resonance technology, and pattern-recognition multi-variable statistical analysis was used to screen out different metabolites. One-way analysis of variance, and Student-Newman-Keuls and the Kruskal-Wallis test were adopted for statistical analysis. Over 400 metabolites were identified in the untargeted metabolomic analysis and 26 metabolites were identified as significantly different among tuberculous, malignant and transudative pleural effusions. These metabolites were predominantly involved in the metabolic pathways of amino acids metabolism, glycometabolism and lipid metabolism. Statistical analysis revealed that eight metabolites contributed to the distinction between the three groups: Tuberculous, malignant and transudative pleural effusion. In the current study, the feasibility of identifying small molecule biochemical profiles in different types of pleural effusion were investigated reveal novel biological insights into the underlying mechanisms. The results provide specific insights into the biology of tubercular, malignant and transudative pleural effusion and may offer novel strategies for the diagnosis and therapy of associated diseases, including tuberculosis, advanced lung cancer and congestive heart failure.

Wagstaff, G

2011-10-01

The physiology and consequences of refeeding syndrome have long been recognised, although its management continues to be debated, despite the recommendations made by The National Institute for Health and Clinical Excellence (NICE) in their guideline 'Nutrition Support in Adults' (2006). The present study aims to assess current dietetic opinion and practice in this area, as well as whether the NICE recommendations have been adopted. An anonymous, self-completed Internet survey was designed investigating current practice and opinions on the NICE (2006) guidance on this subject. A link to the questionnaire was distributed with a covering letter via e-mail to the heads of department of National Health Service Trusts in the London region, UK, requesting that it be disseminated to all dietitians working with adults. After the closing date, all responses were collated and analysed. The survey elicited a 30.8% response rate. Some 89.8% of respondents have read the NICE guidance on Nutrition Support in Adults (2006) and 66.9% have changed their practice regarding refeeding syndrome management as a result. Sixty-two percent do not wait for biochemistry to normalise before commencing nutrition. Ninety-two percent of respondents completed the mini case studies indicating that current practice is inconsistent among dietitians. Neither NICE criteria for recognising patients at risk of refeeding, nor the recommended starting rates are universally followed. Seventy-five percent continue to supplement electrolytes reactively. Although limited by a small sample size, the findings of the present study suggest that dietetic practice regarding refeeding syndrome management remains inconsistent with the recommendations made by NICE, although some aspects have been adopted. © 2011 The Author.

Investigating the current, intended and potential reach of two effective smoking prevention programs in Dutch vocational schools and identifying determinants of school directors' intention to adopt these programs. Cross-sectional survey. Two questionnaires were developed based on the Diffusion of Innovation theory and the I-Change model, focussing on either the 'Healthy School and Stimulants program' (HSS program) or the 'Out-of-school Computer Tailoring program' (CT program). The questionnaires were distributed amongst all Dutch vocational school directors (n = 452) of which 34% completed the questionnaire. The potential reach of the HSS program was 29% whereas the potential reach of the CT program was 5%. Regression analyses revealed that being female, perceiving a higher percentage of smoking students in school, having a personality more open towards change, perceiving a low need for a smoking prevention program, fewer disadvantages of the program, a higher level of self-efficacy towards adopting the program and a more positive social norm towards adopting a smoking prevention program from other school directors resulted in a positive intention towards adopting either program. The present study showed that the reach of effective smoking prevention programs is fairly low. School-based smoking prevention efforts are likely to improve if schools choose to use programs that are proven to be effective, which can be encouraged by adapting existing and newly designed programs to school directors' characteristics and providing easy access to reliable information regarding available programs.

Purpose: To standardize the tube calibration for Elekta XVI cone beam CT (CBCT) systems in order to provide a meaningful estimate of the daily imaging dose and reduce the variation between units in a large centre with multiple treatment units. Methods: Initial measurements of the output from the CBCT systems were made using a Farmer chamber and standard CTDI phantom. The correlation between the measured CTDI and the tube current was confirmed using an Unfors Xi detector which was then used to perform a tube current calibration on each unit. Results: Initial measurements showed measured tube current variations of upmore » to 25% between units for scans with the same image settings. In order to reasonably estimate the imaging dose, a systematic approach to x-ray generator calibration was adopted to ensure that the imaging dose was consistent across all units at the centre and was adopted as part of the routine quality assurance program. Subsequent measurements show that the variation in measured dose across nine units is on the order of 5%. Conclusion: Increasingly, patients receiving radiation therapy have extended life expectancies and therefore the cumulative dose from daily imaging should not be ignored. In theory, an estimate of imaging dose can be made from the imaging parameters. However, measurements have shown that there are large differences in the x-ray generator calibration as installed at the clinic. Current protocols recommend routine checks of dose to ensure constancy. The present study suggests that in addition to constancy checks on a single machine, a tube current calibration should be performed on every unit to ensure agreement across multiple machines. This is crucial at a large centre with multiple units in order to provide physicians with a meaningful estimate of the daily imaging dose.« less

Adoption studies were intended to separate genetic from environmental "causal" factors. In earlier adoption studies, psychiatric diagnostic labels for the adoptive parents were used as a proxy for the multiple dimensions of the family rearing environment. In the Finnish Adoption Study, research design provided the opportunity to study directly the adoptive family rearing environment. For this purpose 33 sub-scales were selected creating what we call Oulu Family Rating Scale (OPAS, Oulun PerheArviointiSkaala). In this paper, the manual for scoring of these sub-scales is presented.

Early Inherited Risk for Anxiety Moderates the Association between Fathers’ Child-Centered Parenting and Early Social Inhibition

Studies of the role of the early environment in shaping children’s risk for anxiety problems have produced mixed results. It is possible that inconsistencies in previous findings result from a lack of consideration of a putative role for inherited influences moderators on the impact of early experiences. Early inherited influences not only contribute to vulnerabilities for anxiety problems throughout the lifespan, but can also modulate the ways that the early environment impacts child outcomes. In the current study, we tested the effects of child-centered parenting behaviors on putative anxiety risk in young children who differed in levels of inherited vulnerability. We tested this using a parent-offspring adoption design and a sample in which risk for anxiety problems and parenting behaviors were assessed in both mothers and fathers. Inherited influences on anxiety problems were assessed as anxiety symptoms in biological parents. Child-centered parenting was observed in adoptive mothers and fathers when children were 9 months old. Social inhibition, an early temperament marker of anxiety risk, was observed at child ages 9 and 18 months. Inherited influences on anxiety problems moderated the link between paternal child-centered parenting during infancy and social inhibition in toddlerhood. For children whose birth parents reported high levels of anxiety symptoms, greater child-centered parenting in adoptive fathers was related to greater social inhibition 9 months later. For children whose birth parents reported low levels of anxiety symptoms, greater child-centered parenting in adoptive fathers was related to less social inhibition across the same period.

Studies of the role of the early environment in shaping children's risk for anxiety problems have produced mixed results. It is possible that inconsistencies in previous findings result from a lack of consideration of a putative role for inherited influences moderators on the impact of early experiences. Early inherited influences not only contribute to vulnerabilities for anxiety problems throughout the lifespan, but can also modulate the ways that the early environment impacts child outcomes. In the current study, we tested the effects of child-centered parenting behaviors on putative anxiety risk in young children who differed in levels of inherited vulnerability. We tested this using a parent-offspring adoption design and a sample in which risk for anxiety problems and parenting behaviors were assessed in both mothers and fathers.

Implantable wireless sensors have been used for real-time monitoring of chemicals and physical conditions of bones, tendons and muscles to diagnose and study orthopedic diseases and injuries. Due to the importance of these sensors in orthopedic care, a critical review, which not only analyzes the underlying technologies but also their clinical implementations and challenges, will provide a landscape view on their current state and their future clinical role. Areas covered: By conducting an extensive literature search and following the leaders of orthopedic implantable wireless sensors, this review covers the battery-powered and battery-free wireless implantable sensor technologies, and describes their implementation for hips, knees, spine, and shoulder stress/strain monitoring. Their advantages, limitations, and clinical challenges are also described. Expert commentary: Currently, implantable wireless sensors are mostly limited for scientific investigations and demonstrative experiments. Although rapid advancement in sensors and wireless technologies will push the reliability and practicality of these sensors for clinical realization, regulatory constraints and financial viability in medical device industry may curtail their continuous adoption for clinical orthopedic applications. In the next five years, these sensors are expected to gain increased interest from researchers, but wide clinical adoption is still unlikely.

Current instructional reforms in undergraduate science, technology, engineering, and mathematics (STEM) courses have focused on enhancing adoption of evidence-based instructional practices among STEM faculty members. These practices have been empirically demonstrated to enhance student learning and attitudes. However, research indicates that instructors often adapt rather than adopt practices, unknowingly compromising their effectiveness. Thus, there is a need to raise awareness of the research-based implementation of these practices, develop fidelity of implementation protocols to understand adaptations being made, and ultimately characterize the true impact of reform efforts based on these practices. Peer instruction (PI) is an example of an evidence-based instructional practice that consists of asking students conceptual questions during class time and collecting their answers via clickers or response cards. Extensive research has been conducted by physics and biology education researchers to evaluate the effectiveness of this practice and to better understand the intricacies of its implementation. PI has also been investigated in other disciplines, such as chemistry and computer science. This article reviews and summarizes these various bodies of research and provides instructors and researchers with a research-based model for the effective implementation of PI. Limitations of current studies and recommendations for future empirical inquiries are also provided. PMID:25713095

The visual efficiency scale currently adopted to determine the legal grade of visual disability associated with visual field loss in Japan is not appropriate for the evaluation of disability regarding daily living activities. We investigated whether Esterman disability score (EDS) is suitable for the assessment of mobility difficulty in patients with visual field loss. The correlation between the EDS calculated from Goldmann's kinetic visual field and the degree of subjective mobility difficulty determined by a questionnaire was investigated in 164 patients with visual field loss. The correlation between the EDS determined using a program built into the Humphrey field analyzer and that calculated from Goldmann's kinetic visual field was also investigated. The EDS based on the kinetic visual field was correlated well with the degree of subjective mobility difficulty, and the EDS measured using the Humphrey field analyzer could be estimated from the kinetic visual field-based EDS. Instead of the currently adopted visual efficiency scale, EDS should be employed for the assessment of mobility difficulty in patients with visual field loss, also to establish new judgment criteria concerning the visual field.

[Policies encouraging price competition in the generic drug market: Lessons from the European experience].

To describe alternative policies aimed at encouraging price competition in generic drug markets in countries with strict price regulation, and to present some case studies drawn from the European experience. Systematic literature review of articles and technical reports published after 1999. The shortcomings in consumer price competition observed in some European generic markets, including Spain, may be reduced through three types of public reimbursement or financing reforms: policies aimed at improving the design of current maximum reimbursement level policies; policies aimed at monitoring competitive prices in order to reimburse real acquisition cost to pharmacies; and, more radical and market-oriented policies such as competitive tendering of public drug purchases. The experience of recent reforms adopted in Germany, Belgium, Holland, Norway, and Sweden offers a useful guide for highly price-regulated European countries, such as Spain, currently characterized by limited consumer price competition and the high discounts offered to pharmacy purchases. Direct price regulation and/or the generic reference pricing systems used to reduce generic drug prices in many European countries can be successfully reformed by adopting measures more closely aimed at encouraging consumer price competition in generic drug markets.

Information system research has stressed the importance of theory in understanding how user perceptions can motivate the use and adoption of technology such as web-based continuing professional development programs for interprofessional education (WCPD-IPE). A systematic review was conducted to provide an information system perspective on the current state of WCPD-IPE program evaluation and how current evaluations capture essential theoretical constructs in promoting technology adoption. Six databases were searched to identify studies evaluating WCPD-IPE. Three investigators determined eligibility of the articles. Evaluation items extracted from the studies were assessed using the Kirkpatrick-Barr framework and mapped to the Benefits Evaluation Framework. Thirty-seven eligible studies yielded 362 evaluation items for analysis. Most items (n = 252) were assessed as Kirkpatrick-Barr level 1 (reaction) and were mainly focused on the quality (information, service, and quality) and satisfaction dimensions of the Benefits Evaluation. System quality was the least evaluated quality dimension, accounting for 26 items across 13 studies. WCPD-IPE use was reported in 17 studies and its antecedent factors were evaluated in varying degrees of comprehensiveness. Although user reactions were commonly evaluated, greater focus on user perceptions of system quality (ie, functionality and performance), usefulness, and usability of the web-based platform is required. Surprisingly, WCPD-IPE use was reported in less than half of the studies. This is problematic as use is a prerequisite to realizing any individual, organizational, or societal benefit of WCPD-IPE. This review proposes an integrated framework which accounts for these factors and provides a theoretically grounded guide for future evaluations.

The Subsonic Fixed Wing Project of NASA s Fundamental Aeronautics Program has adopted a noise reduction goal for new, subsonic, single-aisle, civil aircraft expected to replace current 737 and A320 airplanes. These so-called "N+1" aircraft--designated in NASA vernacular as such since they will follow the current, in-service, "N" airplanes--are hoped to achieve certification noise goal levels of 32 cumulative EPNdB under current Stage 4 noise regulations. A notional, N+1, single-aisle, twinjet transport with ultrahigh bypass ratio turbofan engines is analyzed in this study using NASA software and methods. Several advanced noise-reduction technologies are empirically applied to the propulsion system and airframe. Certification noise levels are predicted and compared with the NASA goal.

On the Consideration of Adoption and Implementation of The Next Generation Science Standards in a Local-Control Context: Supporting the Epistemology of Science through Education Policy

On the Consideration of Adoption and Implementation of The Next Generation Science Standards in a Local-Control Context: Supporting the Epistemology of Science through Education Policy. Christopher C Lazzaro. The primary purpose of this research is to understand how and why members at each of the three levels of the education system within a local-control state made the decisions they did in supporting or hindering the adoption and implementation of the Next Generation Science Standards. This research concentrates on three levels of the education system in a local-control state; 1) the state level, 2) the district level, and 3) the school/teacher level, while investigating the following questions: 1. To what extent, and in what ways, do members in each of the three levels of the state education system advocate for adoption and implementation of the Next Generation Science Standards? 2. Are the members in each of the three levels motivated or compelled to consider adoption and implementation of the Next Generation Science Standards, why or why not? 3. To what extent, and in what ways, do the members in each of the three levels take into account science epistemology in their overall consideration of adoption/implementation of the NGSS? The data drew from a series of interviews from a prior study, "Challenges of Implementing the Next Generation Science Standards in Local-Control States in the U.S." (Sevian, Foster, & Scheff, 2012). After these data were coded and analyzed around the three research questions, this phenomenographic research study identified four key findings: Key Finding 1 - As the District Coordinators are uniquely situated within the state education system to be able to see both the on-the-ground practical implications and the high-level policy pressures of adopting and implementing the NGSS, they reflect the deepest level of awareness of how to best advocate for adoption and implementation of the NGSS. Key Finding 2 - Motivation to adopt and implement the NGSS is highly nuanced. The most significant factor influencing motivation to adopt or implement the NGSS at each level is related to assessment. The reasons assessment affects motivation is different at each level. Key Finding 3 - Each interviewee at each level demonstrated awareness that the NGSS are significantly different from prior standards in some way. While teachers and SSCs sometimes cited the science practices as the critical difference, they were not able to meaningfully elaborate on what "science practices" are. Conversely, the District Coordinators demonstrated a deeper level of awareness and were able to comment more specifically on the practices and how they would affect science education in their state. Key Finding 4 - Regardless of level, the better a participant reflected an awareness of epistemology, the more likely they were to advocate for adoption and implementation of the NGSS. Similarly, the better a participant reflected an awareness of epistemology, the more likely they were motivated to consider adoption and implementation of the NGSS. The implications of the findings in this current study can; inform the supplemental materials and dissemination of information by standards writers, help policy makers engage stakeholders appropriately at each level by illustrating how national reform efforts play out in local-control states, and aid school based employees by identifying how and where they can participate in state level policy discussion and where their input could be valuable.

Spatial-altitudinal and temporal variation of Degree Day Factors (DDFs) in the Upper Indus Basin

Melt contribution from snow and ice in the Hindukush-Karakoram-Himalayan (HKH) region could account for more than 80% of annual river flows in the Upper Indus Basin (UIB). Increase or decrease in precipitation, energy input and glacier reserves can significantly affect water resources of this region. Therefore improved hydrological modelling and accurate future water resources prediction are vital for food production and hydro-power generation for millions of people living downstream, and are intensively needed. In mountain regions Degree Day Factors (DDFs) significantly vary on spatial and altitudinal basis, and are primary inputs of temperature-based hydrological modelling. However previous studies have used different DDFs as calibration parameters without due attention to the physical meaning of the values employed, and these estimates possess significant variability and uncertainty. This study provides estimates of DDFs for various altitudinal zones in the UIB at sub-basin level. Snow, clean ice and ice with debris cover bear different melt rates (or DDFs), therefore areally-averaged DDFs based on snow, clean and debris-covered ice classes in various altitudinal zones have been estimated for all sub-basins of the UIB. Zonal estimates of DDFs in the current study are significantly different from earlier adopted DDFs, hence suggest a revisit of previous hydrological modelling studies. DDFs presented in current study have been validated by using Snowmelt Runoff Model (SRM) in various sub-basins with good Nash Sutcliffe coefficients (R2 > 0.85) and low volumetric errors (Dv<10%). DDFs and methods provided in the current study can be used in future improved hydrological modelling and to provide accurate predictions of future river flows changes. The methodology used for estimation of DDFs is robust, and can be adopted to produce such estimates in other regions of the, particularly in the nearby other HKH basins.

Methods based on the magnetic-acoustic effect are of great significance in studying the electrical imaging properties of biological tissues and currents. The continuous wave method, which is commonly used, can only detect the current amplitude without the sound source position. Although the pulse mode adopted in magneto-acoustic imaging can locate the sonic source, the low measuring accuracy and low SNR has limited its application. In this study, a vector method was used to solve and analyze the magnetic-acoustic signal based on the continuous sine wave mode. This study includes theory modeling of the vector method, simulations to the line model, and experiments with wire samples to analyze magneto-acoustic (MA) signal characteristics. The results showed that the amplitude and phase of the MA signal contained the location information of the sonic source. The amplitude and phase obeyed the vector theory in the complex plane. This study sets a foundation for a new technique to locate sonic sources for biomedical imaging of tissue conductivity. It also aids in studying biological current detecting and reconstruction based on the magneto-acoustic effect.

This study investigates how multiple forcing factors such as rivers, surface marine circulation and winds affect hydrology and biogeochemical processes in the Gulf of Manfredonia and the seas around the Gargano peninsula, in the south-western Adriatic Sea. The study adopted an integrated approach, using in situ and remote sensing data, as well as the output of current models. The data reveal variability in the area's hydrography induced by local freshwater sources, the Western Adriatic Current (WAC) flowing from the north along the Italian coast, and the current patterns under different wind regimes. Specifically, exchange with offshore waters in the gulf induces variability in salinity and biogeochemical content, even within the same season, i.e. winter, in our case. This strong dependence on physical and biogeochemical factors makes the Manfredonia-Gargano ecosystem vulnerable to climate change, which could compromise its important role as a nursery area for the Adriatic Sea.

As a new type of submarine pipeline, the piggyback pipeline has been gradually adopted in engineering practice to enhance the performance and safety of submarine pipelines. However, limited simulation work and few experimental studies have been published on the scour around the piggyback pipeline under steady current. This study numerically and experimentally investigates the local scour of the piggyback pipe under steady current. The influence of prominent factors such as pipe diameter, inflow Reynolds number, and gap between the main and small pipes, on the maximum scour depth have been examined and discussed in detail. Furthermore, one formula to predict the maximum scour depth under the piggyback pipeline has been derived based on the theoretical analysis of scour equilibrium. The feasibility of the proposed formula has been effectively calibrated by both experimental data and numerical results. The findings drawn from this study are instructive in the future design and application of the piggyback pipeline.
