Most strategies for analyzing GMOs in plants and derived food and feed products, are based on the polymerase chain reaction (PCR) technique. In conventional PCR methods, a 'known' sequence between two specific primers is amplified. To the contrary, with the 'anchor PCR' technique, unknown sequences adjacent to a known sequence, can be amplified. Because T-DNA/plant border sequences are being amplified, anchor PCR is the perfect tool for unique identification of transgenes, including non-authorized GMOs. In this work, anchor PCR was applied to characterize the 'transgene locus' and to clarify the complete molecular structure of at least six different commercial transgenic plants. Based on sequences of T-DNA/plant border junctions, obtained by anchor PCR, event specific primers were developed. The junction fragments, together with endogeneous reference gene targets, were cloned in plasmids. The latter were then used as event specific calibrators in real-time PCR, a new technique for the accurate relative quantification of GMOs. We demonstrate here the importance of anchor PCR for identification and the usefulness of plasmid DNA calibrators in quantification strategies for GMOs, throughout the agro-food sector.

Due to the involvement of scientific, industrial, commercial and public sectors of society, the complexity of the issues concerning the safety of genetically modified organisms (GMOs) for the environment, agriculture, and human and animal health calls for a wide coverage of information. Accordingly, development of the field of biotechnology, along with concerns related to the fate of released GMOs, has led to a rapid development of tools for disseminating such information. As a result, there is a growing number of databases aimed at collecting and storing information related to GMOs. Most of the sites deal with information on environmental releases, field trials, transgenes and related sequences, regulations and legislation, risk assessment documents, and literature. Databases are mainly established and managed by scientific, national or international authorities, and are addressed towards scientists, government officials, policy makers, consumers, farmers, environmental groups and civil society representatives. This complexity can lead to an overlapping of information. The purpose of the present review is to analyse the relevant databases currently available on the web, providing comments on their vastly different information and on the structure of the sites pertaining to different users. A preliminary overview on the development of these sites during the last decade, at both the national and international level, is also provided.

Current GMO detection systems have limited abilities to detect unauthorized genetically modified organisms (GMOs). Here, we propose a new workflow, based on next-generation sequencing (NGS) technology, to overcome this problem. In providing information about DNA sequences, this high-throughput workflow can distinguish authorized and unauthorized GMOs by strengthening the tools commonly used by enforcement laboratories with the help of NGS technology. In addition, thanks to its massive sequencing capacity, this workflow could be used to monitor GMOs present in the food and feed chain. In view of its potential implementation by enforcement laboratories, we discuss this innovative approach, its current limitations, and its sustainability of use over time.

The use of GMOs (genetically modified organisms): agricultural biotechnology or agricultural biopolitics?

Science.gov (United States)

Nuti, Marco; Felici, Cristiana; Agnolucci, Monica

2007-01-01

Agricultural biotechnologies embrace a large array of conventional and modern technologies, spanning from composting organic by-products of agriculture to innovative improvement of quality traits of about twenty out of the mostly cultivated plants. In EU a rather restrictive legislative framework has been installed for GMOs, requiring a risk assessment disproportionate with respect to conventional agriculture and organic farming products. The latter are far from being proved safe for human and animal health, and for the environment. Biotechnology of GMOs has been overtaken by biopolitics. On one side there are biotechnological challenges to be tackled, on another side there is plenty of ground for biopolitical decisions about GMOs. Perhaps the era of harsh confrontation could be fruitfully replaced by sensible cooperation, in order to get a sustainable agricultural development.

gmos: Rapid Detection of Genome Mosaicism over Short Evolutionary Distances.

2016-01-01

Prokaryotic and viral genomes are often altered by recombination and horizontal gene transfer. The existing methods for detecting recombination are primarily aimed at viral genomes or sets of loci, since the expensive computation of underlying statistical models often hinders the comparison of complete prokaryotic genomes. As an alternative, alignment-free solutions are more efficient, but cannot map (align) a query to subject genomes. To address this problem, we have developed gmos (Genome MOsaic Structure), a new program that determines the mosaic structure of query genomes when compared to a set of closely related subject genomes. The program first computes local alignments between query and subject genomes and then reconstructs the query mosaic structure by choosing the best local alignment for each query region. To accomplish the analysis quickly, the program mostly relies on pairwise alignments and constructs multiple sequence alignments over short overlapping subject regions only when necessary. This fine-tuned implementation achieves an efficiency comparable to an alignment-free tool. The program performs well for simulated and real data sets of closely related genomes and can be used for fast recombination detection; for instance, when a new prokaryotic pathogen is discovered. As an example, gmos was used to detect genome mosaicism in a pathogenic Enterococcus faecium strain compared to seven closely related genomes. The analysis took less than two minutes on a single 2.1 GHz processor. The output is available in fasta format and can be visualized using an accessory program, gmosDraw (freely available with gmos).

de Vendômois, Joël Spiroux; Cellier, Dominique; Vélot, Christian; Clair, Emilie; Mesnage, Robin; Séralini, Gilles-Eric

2010-10-05

We summarize the major points of international debate on health risk studies for the main commercialized edible GMOs. These GMOs are soy, maize and oilseed rape designed to contain new pesticide residues since they have been modified to be herbicide-tolerant (mostly to Roundup) or to produce mutated Bt toxins. The debated alimentary chronic risks may come from unpredictable insertional mutagenesis effects, metabolic effects, or from the new pesticide residues. The most detailed regulatory tests on the GMOs are three-month long feeding trials of laboratory rats, which are biochemically assessed. The tests are not compulsory, and are not independently conducted. The test data and the corresponding results are kept in secret by the companies. Our previous analyses of regulatory raw data at these levels, taking the representative examples of three GM maize NK 603, MON 810, and MON 863 led us to conclude that hepatorenal toxicities were possible, and that longer testing was necessary. Our study was criticized by the company developing the GMOs in question and the regulatory bodies, mainly on the divergent biological interpretations of statistically significant biochemical and physiological effects. We present the scientific reasons for the crucially different biological interpretations and also highlight the shortcomings in the experimental protocols designed by the company. The debate implies an enormous responsibility towards public health and is essential due to nonexistent traceability or epidemiological studies in the GMO-producing countries.

Molecular profiling--a tool for addressing emerging gaps in the comparative risk assessment of GMOs.

Heinemann, Jack A; Kurenbach, Brigitta; Quist, David

2011-10-01

Assessing the risks of genetically modified organisms (GMOs) is required by both international agreement and domestic legislation. Many view the use of the "omics" tools for profiling classes of molecules as useful in risk assessment, but no consensus has formed on the need or value of these techniques for assessing the risks of all GMOs. In this and many other cases, experts support case-by-case use of molecular profiling techniques for risk assessment. We review the latest research on the applicability and usefulness of molecular profiling techniques for GMO risk assessment. As more and more kinds of GMOs and traits are developed, broader use of molecular profiling in a risk assessment may be required to supplement the comparative approach to risk assessment. The literature-based discussions on the use of profiling appear to have settled on two findings: 1. profiling techniques are reliable and relevant, at least no less so than other techniques used in risk assessment; and 2. although not required routinely, regulators should be aware of when they are needed. The dismissal of routine molecular profiling may be confusing to regulators who then lack guidance on when molecular profiling might be worthwhile. Molecular profiling is an important way to increase confidence in risk assessments if the profiles are properly designed to address relevant risks and are applied at the correct stage of the assessment.

The Precautionary principle: its misunderstandings and misuses in relation to "GMOs".

Science.gov (United States)

Tagliabue, Giovanni

2016-06-25

References to the Precautionary principle (PP) in relation to "GMOs" are commonplace. Those who oppose the DNA recombinant approach to create new agricultural products either have not read the PP (misunderstanding), or they want to exploit the PP for their propaganda while forcing it (misuse). Proponents of a stricter approach to the regulation of biotechnologies must forge a new expression, since the PP is something else - historically and theoretically. In any case, a legitimate very circumspect attitude, to be coherent, must be applied to each and every biotechnology, not only to "GMOs". Copyright © 2016 Elsevier B.V. All rights reserved.

Novel organisms: comparing invasive species, GMOs, and emerging pathogens.

Jeschke, Jonathan M; Keesing, Felicia; Ostfeld, Richard S

2013-09-01

Invasive species, range-expanding species, genetically modified organisms (GMOs), synthetic organisms, and emerging pathogens increasingly affect the human environment. We propose a framework that allows comparison of consecutive stages that such novel organisms go through. The framework provides a common terminology for novel organisms, facilitating knowledge exchange among researchers, managers, and policy makers that work on, or have to make effective decisions about, novel organisms. The framework also indicates that knowledge about the causes and consequences of stage transitions for the better studied novel organisms, such as invasive species, can be transferred to more poorly studied ones, such as GMOs and emerging pathogens. Finally, the framework advances understanding of how climate change can affect the establishment, spread, and impacts of novel organisms, and how biodiversity affects, and is affected by, novel organisms.

2005-05-01

Unknown genetically modified organisms (GMOs) have not undergone a risk evaluation, and hence might pose a danger to health and environment. There are, today, no methods for detecting unknown GMOs. In this paper we propose a novel method intended as a first step in an approach for detecting unknown genetically modified (GM) material in a single plant. A model is designed where biological and combinatorial reduction rules are applied to a set of DNA chip probes containing all possible sequences of uniform length n, creating probes capable of detecting unknown GMOs. The model is theoretically tested for Arabidopsis thaliana Columbia, and the probabilities for detecting inserts and receiving false positives are assessed for various parameters for this organism. From a theoretical standpoint, the model looks very promising but should be tested further in the laboratory. The model and algorithms will be available upon request to the corresponding author.

Mannelli, Ilaria; Minunni, Maria; Tombelli, Sara; Mascini, Marco

2003-03-01

A DNA piezoelectric sensor has been developed for the detection of genetically modified organisms (GMOs). Single stranded DNA (ssDNA) probes were immobilised on the sensor surface of a quartz crystal microbalance (QCM) device and the hybridisation between the immobilised probe and the target complementary sequence in solution was monitored. The probe sequences were internal to the sequence of the 35S promoter (P) and Nos terminator (T), which are inserted sequences in the genome of GMOs regulating the transgene expression. Two different probe immobilisation procedures were applied: (a) a thiol-dextran procedure and (b) a thiol-derivatised probe and blocking thiol procedure. The system has been optimised using synthetic oligonucleotides, which were then applied to samples of plasmidic and genomic DNA isolated from the pBI121 plasmid, certified reference materials (CRM), and real samples amplified by the polymerase chain reaction (PCR). The analytical parameters of the sensor have been investigated (sensitivity, reproducibility, lifetime etc.). The results obtained showed that both immobilisation procedures enabled sensitive and specific detection of GMOs, providing a useful tool for screening analysis in food samples.

An innovative and integrated approach based on DNA walking to identify unauthorised GMOs.

2014-03-15

In the coming years, the frequency of unauthorised genetically modified organisms (GMOs) being present in the European food and feed chain will increase significantly. Therefore, we have developed a strategy to identify unauthorised GMOs containing a pCAMBIA family vector, frequently present in transgenic plants. This integrated approach is performed in two successive steps on Bt rice grains. First, the potential presence of unauthorised GMOs is assessed by the qPCR SYBR®Green technology targeting the terminator 35S pCAMBIA element. Second, its presence is confirmed via the characterisation of the junction between the transgenic cassette and the rice genome. To this end, a DNA walking strategy is applied using a first reverse primer followed by two semi-nested PCR rounds using primers that are each time nested to the previous reverse primer. This approach allows to rapidly identify the transgene flanking region and can easily be implemented by the enforcement laboratories. Copyright © 2013 The Authors. Published by Elsevier Ltd..

Nowadays most animal feed products imported into Europe have a GMO (genetically modified organism) label. This means that they contain European Union (EU)-authorized GMOs. For enforcement of these labeling requirements, it is necessary, with the rising number of EU-authorized GMOs, to perform an increasing number of analyses. In addition to this, it is necessary to test products for the potential presence of EU-unauthorized GMOs. Analysis for EU-authorized and -unauthorized GMOs in animal feed has thus become laborious and expensive. Initial screening steps may reduce the number of GMO identification methods that need to be applied, but with the increasing diversity also screening with GMO elements has become more complex. For the present study, the application of an informative detailed 24-element screening and subsequent identification strategy was applied in 50 animal feed samples. Almost all feed samples were labeled as containing GMO-derived materials. The main goal of the study was therefore to investigate if a detailed screening strategy would reduce the number of subsequent identification analyses. An additional goal was to test the samples in this way for the potential presence of EU-unauthorized GMOs. Finally, to test the robustness of the approach, eight of the samples were tested in a concise interlaboratory study. No significant differences were found between the results of the two laboratories.

A covert authentication and security solution for GMOs.

Science.gov (United States)

Mueller, Siguna; Jafari, Farhad; Roth, Don

2016-09-21

Proliferation and expansion of security risks necessitates new measures to ensure authenticity and validation of GMOs. Watermarking and other cryptographic methods are available which conceal and recover the original signature, but in the process reveal the authentication information. In many scenarios watermarking and standard cryptographic methods are necessary but not sufficient and new, more advanced, cryptographic protocols are necessary. Herein, we present a new crypto protocol, that is applicable in broader settings, and embeds the authentication string indistinguishably from a random element in the signature space and the string is verified or denied without disclosing the actual signature. Results show that in a nucleotide string of 1000, the algorithm gives a correlation of 0.98 or higher between the distribution of the codon and that of E. coli, making the signature virtually invisible. This algorithm may be used to securely authenticate and validate GMOs without disclosing the actual signature. While this protocol uses watermarking, its novelty is in use of more complex cryptographic techniques based on zero knowledge proofs to encode information.

In most countries, systems are in place to analyse food products for the potential presence of genetically modified organisms (GMOs), to enforce labelling requirements and to screen for the potential presence of unauthorised GMOs. With the growing number of GMOs on the world market, a larger diversity of methods is required for informative analyses. In this paper, the specificity of an extended screening set consisting of 32 screening methods to identify different crop species (endogenous genes) and GMO elements was verified against 59 different GMO reference materials. In addition, a cost- and time-efficient strategy for DNA isolation, screening and identification is presented. A module for semiautomated analysis of the screening results and planning of subsequent event-specific tests for identification has been developed. The Excel-based module contains information on the experimentally verified specificity of the element methods and of the EU authorisation status of the GMO events. If a detected GMO element cannot be explained by any of the events as identified in the same sample, this may indicate the presence of an unknown unauthorised GMO that may not yet have been assessed for its safety for humans, animals or the environment.

It’s argued that while initially new GMOs add to the global stock of biodiversity, in the long-term they result in a decline in biodiversity. Various mechanisms that bring about this decline in genetic diversity are identified. It is suggested that due to evolutionary forces, the desirable genetic properties of some GMO may be eroded in the long-term. They are unlikely to be sustained i...

The Ethics of Introducing GMOs into sub-Saharan Africa: Considerations from the sub-Saharan African Theory of Ubuntu.

Science.gov (United States)

Komparic, Ana

2015-11-01

A growing number of countries in sub-Saharan Africa are considering legalizing the growth of genetically modified organisms (GMOs). Furthermore, several projects are underway to develop transgenic crops tailored to the region. Given the contentious nature of GMOs and prevalent anti-GMO sentiments in Africa, a robust ethical analysis examining the concerns arising from the development, adoption, and regulation of GMOs in sub-Saharan Africa is warranted. To date, ethical analyses of GMOs in the global context have drawn predominantly on Western philosophy, dealing with Africa primarily on a material level. Yet, a growing number of scholars are articulating and engaging with ethical theories that draw upon sub-Saharan African value systems. One such theory, Ubuntu, is a well-studied sub-Saharan African communitarian morality. I propose that a robust ethical analysis of Africa's agricultural future necessitates engaging with African moral theory. I articulate how Ubuntu may lead to a novel and constructive understanding of the ethical considerations for introducing GMOs into sub-Saharan Africa. However, rather than reaching a definitive prescription, which would require significant engagement with local communities, I consider some of Ubuntu's broader implications for conceptualizing risk and engaging with local communities when evaluating GMOs. I conclude by reflecting on the implications of using local moral theory in bioethics by considering how one might negotiate between universalism and particularism in the global context. Rather than advocating for a form of ethical relativism, I suggest that local moral theories shed light on salient ethical considerations that are otherwise overlooked. © 2015 John Wiley & Sons Ltd.

We present the complete optical transmission spectrum of the hot Jupiter WASP-4b from 440 to 940 nm at R  ∼ 400–1500 obtained with the Gemini Multi-Object Spectrometers (GMOS); this is the first result from a comparative exoplanetology survey program of close-in gas giants conducted with GMOS. WASP-4b has an equilibrium temperature of 1700 K and is favorable to study in transmission due to its large scale height (370 km). We derive the transmission spectrum of WASP-4b using four transits observed with the MOS technique. We demonstrate repeatable results across multiple epochs with GMOS, and derive a combined transmission spectrum at a precision about twice above photon noise, which is roughly equal to one atmospheric scale height. The transmission spectrum is well fitted with a uniform opacity as a function of wavelength. The uniform opacity and absence of a Rayleigh slope from molecular hydrogen suggest that the atmosphere is dominated by clouds with condensate grain sizes of ∼1  μ m. This result is consistent with previous observations of hot Jupiters since clouds have been seen in planets with similar equilibrium temperatures to WASP-4b. We describe a custom pipeline that we have written to reduce GMOS time-series data of exoplanet transits, and present a thorough analysis of the dominant noise sources in GMOS, which primarily consist of wavelength- and time-dependent displacements of the spectra on the detector, mainly due to a lack of atmospheric dispersion correction.

Here, we developed a loop-mediated isothermal amplification (LAMP) assay for 11 common transgenic target DNA in GMOs. Six sets of LAMP primer candidates for each target were designed and their specificity, sensitivity, and reproductivity were evaluated. With the optimized LAMP primers, this LAMP assay was simply run within 45-60 min to detect all these targets in GMOs tested. The sensitivity, specificity, and reproductivity of the LAMP assay were further analyzed in comparison with those of Real-Time PCR. In consistent with real-time PCR, detection of 0.5% GMOs in equivalent background DNA was possible using this LAMP assay for all targets. In comparison with real-time PCR, the LAMP assay showed the same results with simple instruments. Hence, the LAMP assay developed can provide a rapid and simple approach for routine screening as well as specific events detection of many GMOs.

In order to provide a system fully integrated with qPCR screening, usually used in GMO routine analysis, as well as being able to detect, characterize and identify a broad spectrum of GMOs in food/feed matrices, two bidirectional DNA walking methods targeting p35S or tNOS, the most common transgenic elements found in GM crops, were developed. These newly developed DNA walking methods are completing the previously implemented DNA walking method targeting the t35S pCAMBIA element. Food/feed matrices containing transgenic crops (Bt rice or MON863 maize) were analysed using the integrated DNA walking system. First, the newly developed DNA walking methods, anchored on the sequences used for the p35S or tNOS qPCR screening, were tested on Bt rice that contains these two transgenic elements. Second, the methods were assessed on a maize sample containing a low amount of the GM MON863 event, representing a more complex matrix in terms of genome size and sensitivity. Finally, to illustrate its applicability in GMO routine analysis by enforcement laboratories, the entire workflow of the integrated strategy, including qPCR screening to detect the potential presence of GMOs and the subsequent DNA walking methods to characterize and identify the detected GMOs, was applied on a GeMMA Scheme Proficiency Test matrix. Via the characterization of the transgene flanking region between the transgenic cassette and the plant genome as well as of a part of the transgenic cassette, the presence of GMOs was properly confirmed or infirmed in all tested samples. Due to their simple procedure and their short time-frame to get results, the developed DNA walking methods proposed here can be easily implemented in GMO routine analysis by the enforcement laboratories. In providing crucial information about the transgene flanking regions and/or the transgenic cassettes, this DNA walking strategy is a key molecular tool to prove the presence of GMOs in any given food/feed matrix.

Full Text Available La majorité du public manifeste une réticence voire une opposition face aux produits génétiquement modifiés. Quant aux arguments avancés à ce propos, la santé occupe la place centrale. En ce sens, ces produits sont considérés comme des entités pathogènes qui nuisent à la santé du consommateur, menacent sa vie et celle des futures générations. Ce qui nourrit le sentiment de peur des OGM (ou organismes génétiquement modifiés, c'est aussi leur caractère « maléfique », global et irréversible. Car ces produits, en affectant la faune et la flore, portent atteinte à l'équilibre de l'écosystème et à la matrice de la vie. Outre ces risques sur la santé et sur l'équilibre de l'écosystème, les OGM sont représentés comme une atteinte à l'intégrité du pays. En ce sens, ils engendrent la dépossession de ses richesses et de ses spécificités culturelles, par conséquent sa misère et sa subordination aux puissances étrangères et aux multinationales détentrices des OGM. Toutes ces considérations font des OGM le synonyme d'un désordre naturel et social. Certains vont jusqu'à les qualifier de « mal total » ou de « véritable désastre ». L'une des conclusions de l'étude est que le discours populaire relatif aux OGM serait la transposition d'un vécu social contesté et le reflet d'un rapport conflictuel à la société moderne.Most people are reticent, even opposed to Genetically Modified products. Among reasons against GMOs we find that health occupies the most important place: such products are considered as harmful entities for consumers' health, a threat to their life and to future generations. What also feeds the feeling of fear towards GMOs is their “evil”, global, irreversible and evolutionary nature since these products, by affecting fauna and flora, can unbalance the ecosystem equilibrium and the core of life. Apart from the danger they represent for the ecosystem, GMOs are perceived as being a

Genetically modified organisms (GMOs) and derived food and feed products are subject to a risk analysis and regulatory approval before they can enter the market in the European Union (EU). In this risk analysis process, the role of the European Food Safety Authority (EFSA), which was created in 2002 in response to multiple food crises, is to independently assess and provide scientific advice to risk managers on any possible risks that the use of GMOs may pose to human and animal health and the environment. EFSA's scientific advice is elaborated by its GMO Panel with the scientific support of several working groups and EFSA's GMO Unit. This review presents EFSA's scientific activities and highlights its achievements on the risk assessment of GMOs for the first 10 years of its existence. Since 2002, EFSA has issued 69 scientific opinions on genetically modified (GM) plant market registration applications, of which 62 for import and processing for food and feed uses, six for cultivation and one for the use of pollen (as or in food), and 19 scientific opinions on applications for marketing products made with GM microorganisms. Several guidelines for the risk assessment of GM plants, GM microorganisms and GM animals, as well as on specific issues such as post-market environmental monitoring (PMEM) were elaborated. EFSA also provided scientific advice upon request of the European Commission on safeguard clause and emergency measures invoked by EU Member States, annual PMEM reports, the potential risks of new biotechnology-based plant breeding techniques, evaluations of previously assessed GMOs in the light of new scientific publications, and the use of antibiotic resistance marker genes in GM plants. Future challenges relevant to the risk assessment of GMOs are discussed. EFSA's risk assessments of GMO applications ensure that data are analysed and presented in a way that facilitates scientifically sound decisions that protect human and animal health and the environment.

Recently, we developed a DNA walking system for the detection and characterization of a broad spectrum of GMOs in routine analysis of food/feed matrices. Here, we present a new version with improved throughput and sensitivity by coupling the DNA walking system to Pacific Bioscience® Next-generation sequencing technology. The performance of the new strategy was thoroughly assessed through several assays. First, we tested its detection and identification capability on grains with high or low GMO content. Second, the potential impacts of food processing were investigated using rice noodle samples. Finally, GMO mixtures and a real-life sample were analyzed to illustrate the applicability of the proposed strategy in routine GMO analysis. In all tested samples, the presence of multiple GMOs was unambiguously proven by the characterization of transgene flanking regions and the combinations of elements that are typical for transgene constructs.

2003-01-01

In Europe, there seems to be widespread, morally based scepticism about the use of GMOs in food production. In response to this scepticism, the revised EU directive 2001/18/EC on the deliberate release into the environment of genetically modified organisms stresses the importance of respecting...... assessment and approval of GMOs outlined in the directive. An environmental risk assessment views the world through a "risk window" that only makes visible that which has been predefined as a relevant risk. The importance of the value judgements that define the risk window consists in limiting...

Current PCR Methods for the Detection, Identification and Quantification of Genetically Modified Organisms(GMOs: a Brief Review

Gadani F

2014-12-01

Full Text Available Analytical methods based on the polymerase chain reaction (PCR technology are increasingly used for the detection of deoxyribonucleic acid (DNA sequences associated with genetically modified organisms (GMOs. In the European Union and Switzerland, mandatory labeling of novel foods and food ingredients consisting of, or containing GMOs is required according to food regulations and is triggered by the presence of newly introduced foreign DNA sequences, or newly expressed proteins. In order to meet regulatory and consumer demand, numerous PCR-based methods have been developed which can detect, identify and quantify GMOs in agricultural crops, food and feed. Moreover, the determination of genetic identity allows for segregation and traceability (identity preservation throughout the supply chain of GM crops that have been enhanced with value-added quality traits. Prerequisites for GMO detection include a minimum amount of the target gene and prior knowledge of the type of genetic modification, such as virus or insect resistance traits, including controlling elements (promoters and terminators. Moreover, DNA extraction and purification is a critical step for the preparation of PCR-quality samples, particularly for processed agricultural crops such as tobacco. This paper reviews the state-of-the-art of PCR-based method development for the qualitative and quantitative determination and identification of GMOs, and includes a short summary of official and validated GMO detection methods.

Atmospheric mercury concentrations observed at ground-based monitoring sites globally distributed in the framework of the GMOS network

Full Text Available Long-term monitoring of data of ambient mercury (Hg on a global scale to assess its emission, transport, atmospheric chemistry, and deposition processes is vital to understanding the impact of Hg pollution on the environment. The Global Mercury Observation System (GMOS project was funded by the European Commission (http://www.gmos.eu and started in November 2010 with the overall goal to develop a coordinated global observing system to monitor Hg on a global scale, including a large network of ground-based monitoring stations, ad hoc periodic oceanographic cruises and measurement flights in the lower and upper troposphere as well as in the lower stratosphere. To date, more than 40 ground-based monitoring sites constitute the global network covering many regions where little to no observational data were available before GMOS. This work presents atmospheric Hg concentrations recorded worldwide in the framework of the GMOS project (2010–2015, analyzing Hg measurement results in terms of temporal trends, seasonality and comparability within the network. Major findings highlighted in this paper include a clear gradient of Hg concentrations between the Northern and Southern hemispheres, confirming that the gradient observed is mostly driven by local and regional sources, which can be anthropogenic, natural or a combination of both.

Limits of the current EU regulatory framework on GMOs: risk of not authorized GM event-traces in imports

Directory of Open Access Journals (Sweden)

Roïz Julie

2014-11-01

Full Text Available Since their first commercialization in the 1990’s, the number of genetically modified organisms (GMOs cultivated around the world has steadily increased. This development has been accompanied by the development of regulatory and policy environments which vary from one country to another. Today, the European food and feed sectors are faced with the increasing risk of finding traces of not authorized GMOs in imports. Under the EU zero tolerance for unapproved GMOs, this situation may lead to trade disruptions with important cost implications. A regulatory environment which minimizes the risk of such disruption is therefore indispensable. To address this issue, the EU has adopted the “technical solution” but this remains insufficient to provide the necessary legal certainty which is needed to operate in such context. More comprehensive approaches are considered globally through low level presence policies.

The atmospheric deposition of mercury (Hg) occurs via several mechanisms, including dry and wet scavenging by precipitation events. In an effort to understand the atmospheric cycling and seasonal depositional characteristics of Hg, wet deposition samples were collected for approximately 5 years at 17 selected GMOS monitoring sites located in the Northern and Southern hemispheres in the framework of the Global Mercury Observation System (GMOS) project. Total mercury (THg) exhibited annual and seasonal patterns in Hg wet deposition samples. Interannual differences in total wet deposition are mostly linked with precipitation volume, with the greatest deposition flux occurring in the wettest years. This data set provides a new insight into baseline concentrations of THg concentrations in precipitation worldwide, particularly in regions such as the Southern Hemisphere and tropical areas where wet deposition as well as atmospheric Hg species were not investigated before, opening the way for future and additional simultaneous measurements across the GMOS network as well as new findings in future modeling studies.

Chronic health effects are increasing in the world such as cancers, hormonal, reproductive, nervous, or immune diseases, even in young people. During regulatory toxicological subchronic tests to prevent these on mammalian health, prior commercialization of chemicals, including pesticides and drugs, or GMOs, some statistically significant findings may be revealed. This discussion is about the need to investigate the relevant criteria to consider those as biologically significant. The sex differences and the non linear dose or time related effects should be considered in contrast to the claims of a Monsanto-supported expert panel about a GMO, the MON 863 Bt maize, but also for pesticides or drugs, in particular to reveal hormone-dependent diseases and first signs of toxicities.

Full Text Available Abstract Background To maintain EU GMO regulations, producers of new GM crop varieties need to supply an event-specific method for the new variety. As a result methods are nowadays available for EU-authorised genetically modified organisms (GMOs, but only to a limited extent for EU-non-authorised GMOs (NAGs. In the last decade the diversity of genetically modified (GM ingredients in food and feed has increased significantly. As a result of this increase GMO laboratories currently need to apply many different methods to establish to potential presence of NAGs in raw materials and complex derived products. Results In this paper we present an innovative method for detecting (approved GMOs as well as the potential presence of NAGs in complex DNA samples containing different crop species. An optimised protocol has been developed for padlock probe ligation in combination with microarray detection (PPLMD that can easily be scaled up. Linear padlock probes targeted against GMO-events, -elements and -species have been developed that can hybridise to their genomic target DNA and are visualised using microarray hybridisation. In a tenplex PPLMD experiment, different genomic targets in Roundup-Ready soya, MON1445 cotton and Bt176 maize were detected down to at least 1%. In single experiments, the targets were detected down to 0.1%, i.e. comparable to standard qPCR. Conclusion Compared to currently available methods this is a significant step forward towards multiplex detection in complex raw materials and derived products. It is shown that the PPLMD approach is suitable for large-scale detection of GMOs in real-life samples and provides the possibility to detect and/or identify NAGs that would otherwise remain undetected.

Sprovieri F.

2013-04-01

Full Text Available Consistent, high-quality measurements of atmospheric mercury (Hg are necessary in order to better understand Hg emissions, transport, and deposition on a global scale. Although the number of atmospheric Hg monitoring stations has increased in recent years, the available measurement database is limited and there are many regions of the world where measurements have not been extensively performed. Long-term atmospheric Hg monitoring and additional ground-based monitoring sites are needed in order to generate datasets that will offer new insight and information about the global scale trends of atmospheric Hg emissions and deposition. In the framework of the Global Mercury Observation System (GMOS project, a coordinated global observational network for atmospheric Hg is being established. The overall research strategy of GMOS is to develop a state-of-the-art observation system able to provide information on the concentration of Hg species in ambient air and precipitation on the global scale. This network is being developed by integrating previously established ground-based atmospheric Hg monitoring stations with newly established GMOS sites that are located both at high altitude and sea level locations, as well as in climatically diverse regions. Through the collection of consistent, high-quality atmospheric Hg measurement data, we seek to create a comprehensive assessment of atmospheric Hg concentrations and their dependence on meteorology, long-range atmospheric transport and atmospheric emissions.

Biosafety of genetically modified organisms (GMOs) and their derivatives is still a major topic in the agenda of government and societies worldwide. The aim of this review is to bring into light that data that supported the decision taken back in 1998 as an exercise to stimulate criticism from the scientific community for upcoming discussions and to avoid emotional and senseless arguments that could jeopardize future development in the field. It must be emphasized that Roundup Ready soybean is just one example of how biotechnology can bring in significant advances for society, not only through increased productivity, but also with beneficial environmental impact, thereby allowing more rational use of agricultural pesticides for improvement of the soil conditions. The adoption of agricultural practices with higher yield will also allow better distribution of income among small farmers. New species of genetically modified plants will soon be available and society should be capable of making decisions in an objective and well-informed manner, through collegiate bodies that are qualified in all aspects of biosafety and environmental impact.

Risk Management And Liability For EnvironmentalL Harm Caused By GMOS – The South African Regulatory Framework

Directory of Open Access Journals (Sweden)

L Feris

2006-05-01

Full Text Available Biotechnology is still relatively new and as with any new technology, it carries some level of risk. This necessitates appropriate risk assessments and appropriate risk management. One element of risk management however, is taking into account that during the production, development, transport or release of a GMO it may cause injury to person, property or the environment, regardless of risk management procedures. This calls for the existence of a liability regime that will place some legal responsibility on the party responsible for the harm. This paper assesses the South African regulatory framework of relevance to GMOs, which is composed of a fragmented set of laws that deals with risk assessment, risk management and liability for damage to the environment. It discusses the GMO Act as the principle legislation regulation GMOs and also the recent amendment thereof and also consider other legislation such as the ECA, NEMA and NEMA Biodiversity Act in an attempt to determine whether the regulatory framework addresses risk management and liability in an effective and adequate manner. It comes to the conclusion that South Africa does not as yet have a satisfactory legal regime that provides for risk management and liability in the context of GMOs.

The issue of GMOs arouses constantly strong emotions in public discourse. At the same time opinions of people particularly interested in this issues such as researchers, or potential users of this technology (e.g. farmers) are rarely subjected to analysis. Moreover, lack of knowledge about the flow of information "from the laboratory to the consumer" hinders implementation of any changes in this field. By using triangulation (combining quantitative and qualitative research and the use of various research tools) we explored the attitudes of Polish scientists, agricultural advisers and farmers (large scale agricultural producers) to the use of GMOs in the economy. On the basis of the performed research we diagnosed the effectiveness of information flow among these groups about transgenic organisms. Copyright © 2013 Elsevier B.V. All rights reserved.

Need for an "integrated safety assessment" of GMOs, linking food safety and environmental considerations.

Science.gov (United States)

Haslberger, Alexander G

2006-05-03

Evidence for substantial environmental influences on health and food safety comes from work with environmental health indicators which show that agroenvironmental practices have direct and indirect effects on human health, concluding that "the quality of the environment influences the quality and safety of foods" [Fennema, O. Environ. Health Perspect. 1990, 86, 229-232). In the field of genetically modified organisms (GMOs), Codex principles have been established for the assessment of GM food safety and the Cartagena Protocol on Biosafety outlines international principles for an environmental assessment of living modified organisms. Both concepts also contain starting points for an assessment of health/food safety effects of GMOs in cases when the environment is involved in the chain of events that could lead to hazards. The environment can act as a route of unintentional entry of GMOs into the food supply, such as in the case of gene flow via pollen or seeds from GM crops, but the environment can also be involved in changes of GMO-induced agricultural practices with relevance for health/food safety. Examples for this include potential regional changes of pesticide uses and reduction in pesticide poisonings resulting from the use of Bt crops or influences on immune responses via cross-reactivity. Clearly, modern methods of biotechnology in breeding are involved in the reasons behind the rapid reduction of local varieties in agrodiversity, which constitute an identified hazard for food safety and food security. The health/food safety assessment of GM foods in cases when the environment is involved needs to be informed by data from environmental assessment. Such data might be especially important for hazard identification and exposure assessment. International organizations working in these areas will very likely be needed to initiate and enable cooperation between those institutions responsible for the different assessments, as well as for exchange and analysis of

Detection of GMO material in crop and food samples is the primary step in GMO monitoring and regulation, with the increasing number of GM events in the world market requiring detection solutions with high multiplexing capacity. In this study, we test the suitability of a high-density oligonucleotide microarray platform for direct, quantitative detection of GMOs found in the Turkish feed market. We tested 1830 different 60nt probes designed to cover the GM cassettes from 12 different GM cultivars (3 soya, 9 maize), as well as plant species-specific and contamination controls, and developed a data analysis method aiming to provide maximum throughput and sensitivity. The system was able specifically to identify each cultivar, and in 10/12 cases was sensitive enough to detect GMO DNA at concentrations of ⩽1%. These GMOs could also be quantified using the microarray, as their fluorescence signals increased linearly with GMO concentration. Copyright © 2015 Elsevier Ltd. All rights reserved.

Food and feed samples were randomly collected from different sources, including local and imported materials from the Syrian local market. These included maize, barley, soybean, fresh food samples and raw material. GMO detection was conducted by PCR and nested PCR-based techniques using specific primers for the most used foreign DNA commonly used in genetic transformation procedures, i.e., 35S promoter, T-nos, epsps, cryIA(b) gene and nptII gene. The results revealed for the first time in Syria the presence of GM foods and feeds with glyphosate-resistant trait of P35S promoter and NOS terminator in the imported soybean samples with high frequency (5 out of the 6 imported soybean samples). While, tests showed negative results for the local samples. Also, tests revealed existence of GMOs in two imported maize samples detecting the presence of 35S promoter and nos terminator. Nested PCR results using two sets of primers confirmed our data. The methods applied in the brief data are based on DNA analysis by Polymerase Chain Reaction (PCR). This technique is specific, practical, reproducible and sensitive enough to detect up to 0.1% GMO in food and/or feedstuffs. Furthermore, all of the techniques mentioned are economic and can be applied in Syria and other developing countries. For all these reasons, the DNA-based analysis methods were chosen and preferred over protein-based analysis.

Within the Global Mercury Observation System (GMOS) project, long-term continuous measurements of total gaseous mercury (TGM) were carried out by a monitoring station located at Celestun, Yucatan, Mexico, a coastal site along the Gulf of Mexico. The measurements covered the period from January 28th to October 17th, 2012. TGM data, at the Celestun site, were obtained using a high-resolution mercury vapor analyzer. TGM data show values from 0.50 to 2.82 ng/m(3) with an annual average concentration of 1.047 ± 0.271 ng/m(3). Multivariate analyses of TGM and meteorological variables suggest that TGM is correlated with the vertical air mass distribution in the atmosphere, which is influenced by diurnal variations in temperature and relative humidity. Diurnal variation is characterized by higher nighttime mercury concentrations, which might be influenced by convection currents between sea and land. The back trajectory analysis confirmed that local sources do not significantly influence TGM variations. This study shows that TGM monitoring at the Celestun site fulfills GMOS goals for a background site.

For years, an increasing number and diversity of genetically modified plants has been grown on a commercial scale. The need for detection and identification of these genetically modified organisms (GMOs) calls for broad and at the same time flexible high throughput testing methods. Here we describe the development and validation of a hexaplex real-time polymerase chain reaction (PCR) screening assay covering more than 100 approved GMOs containing at least one of the GMO targets of the assay. The assay comprises detection systems for Cauliflower Mosaic Virus 35S promoter, Agrobacterium tumefaciens NOS terminator, Figwort Mosaic Virus 34S promoter and two construct-specific sequences present in novel genetically modified soybean and maize that lack common screening elements. Additionally a detection system for an internal positive control (IPC) indicating the presence or absence of PCR inhibiting substances was included. The six real-time PCR systems were allocated to five detection channels showing no significant crosstalk between the detection channels. As part of an extensive validation, a limit of detection (LOD(abs)) GMOs in processed and unprocessed food, feed and seed samples with high efficiency.

The majority of feed products in industrialised countries contains materials derived from genetically modified organisms (GMOs). In parallel, the number of reports of unauthorised GMOs (UGMOs) is gradually increasing. There is a lack of specific detection methods for UGMOs, due to the absence of detailed sequence information and reference materials. In this research, an adapted genome walking approach was developed, called ALF: Amplification of Linearly-enriched Fragments. Coupling of ALF to NGS aims for simultaneous detection and identification of all GMOs, including UGMOs, in one sample, in a single analysis. The ALF approach was assessed on a mixture made of DNA extracts from four reference materials, in an uneven distribution, mimicking a real life situation. The complete insert and genomic flanking regions were known for three of the included GMO events, while for MON15985 only partial sequence information was available. Combined with a known organisation of elements, this GMO served as a model for a UGMO. We successfully identified sequences matching with this organisation of elements serving as proof of principle for ALF as new UGMO detection strategy. Additionally, this study provides a first outline of an automated, web-based analysis pipeline for identification of UGMOs containing known GM elements.

main objective the analyses of different researches on the perception of consumers, farmers and citizens in general in relation to the use of Genetically Modified Organisms (GMOs in food production and consumption. We established a comparative perspective between the researches developed in Brazil, in Europe, in Asia and in the United States. The researches themselves, with their results, had become a central part on the debates about GMOs risks, both among the sectors that emphasized them as well as in the sectors that denied them. One of our key arguments is that in Brazil there is a lack of researches in the subject on public perception of risk. This situation can be considered as an evidence of the lack of interest in the public participation in the debates about GMOs. These had been mainly controlled by organized social actors, without any or with only partial representation. Also the limited number of researches in Brazil showed the limits of the marketing area (that had assumed these work in other countries, still assuming a positivistic perspective on the consumers. And finally, we argue that the in the Brazilian academic field there is a no problematization of conflicts or consensus between lay and expert people in the debate about GMOs risks. In the first part of the article we focused in the analysis of the types of researches that had taken place in Brazil, choosing the ones that had been used as supporting different arguments in relation to GMOs by the social actors involved in the debate. In the second part we considered the researches developed in other parts of the world. And in the third part, we analyse the constrains and opportunities that different researches here selected as the most interesting can present for the understanding of the global debate on GMOs and also showing one interesting road for future researches in Brazil on public perception, not only of GMOs, but also of science.

Both cisgenesis and transgenesis are plant breeding techniques that can be used to introduce new genes into plant genomes. However, transgenesis uses gene(s) from a non-plant organism or from a donor plant that is sexually incompatible with the recipient plant while cisgenesis involves the introduction of gene(s) from a crossable--sexually compatible--plant. Traditional breeding techniques could possibly achieve the same results as those from cisgenesis, but would require a much larger timeframe. Cisgenesis allows plant breeders to enhance an existing cultivar more quickly and with little to no genetic drag. The current regulation in the European Union (EU) on genetically modified organisms (GMOs) treats cisgenic plants the same as transgenic plants and both are mandatorily labeled as GMOs. This study estimates European consumers' willingness-to-pay (WTP) for rice labeled as GM, cisgenic, with environmental benefits (which cisgenesis could provide), or any combination of these three attributes. Data were collected from 3,002 participants through an online survey administered in Belgium, France, the Netherlands, Spain and the United Kingdom in 2013. Censored regression models were used to model consumers' WTP in each country. Model estimates highlight significant differences in WTP across countries. In all five countries, consumers are willing-to-pay a premium to avoid purchasing rice labeled as GM. In all countries except Spain, consumers have a significantly higher WTP to avoid consuming rice labeled as GM compared to rice labeled as cisgenic, suggesting that inserting genes from the plant's own gene pool is more acceptable to consumers. Additionally, French consumers are willing-to-pay a premium for rice labeled as having environmental benefits compared to conventional rice. These findings suggest that not all GMOs are the same in consumers' eyes and thus, from a consumer preference perspective, the differences between transgenic and cisgenic products are

The polymerase chain reaction (PCR) is the current state of the art technique for DNA-based detection of Genetically Modified Organisms (GMOs). A typical control strategy starts by analyzing a sample for the presence of target sequences (GM-elements) known to be present in many GMOs. Positive findings from this "screening" are then confirmed with GM (event) specific test methods. A reliable knowledge of which GMOs are detected by combinations of GM-detection methods is thus crucial to minimize the verification efforts. In this article, we describe a novel platform that links the information of two unique databases built and maintained by the European Union Reference Laboratory for Genetically Modified Food and Feed (EU-RL GMFF) at the Joint Research Centre (JRC) of the European Commission, one containing the sequence information of known GM-events and the other validated PCR-based detection and identification methods. The new platform compiles in silico determinations of the detection of a wide range of GMOs by the available detection methods using existing scripts that simulate PCR amplification and, when present, probe binding. The correctness of the information has been verified by comparing the in silico conclusions to experimental results for a subset of forty-nine GM events and six methods. The JRC GMO-Matrix is unique for its reliance on DNA sequence data and its flexibility in integrating novel GMOs and new detection methods. Users can mine the database using a set of web interfaces that thus provide a valuable support to GMO control laboratories in planning and evaluating their GMO screening strategies. The platform is accessible at http://gmo-crl.jrc.ec.europa.eu/jrcgmomatrix/ .

This is the first step of a long-term Brazilian–Argentinian collaboration for the study of GC systems in early-type galaxies. In the context of this collaboration, we obtained deep NIR photometric data in two different bands (J and K s, which were later combined with high quality optical Gemini + GMOS photometry previously obtained by the Argentinian team. This allowed us to obtain different color indices, less sensitive to the effect of horizontal branch (HB stars for several hundreds of GC candidates, and to make an initial assessment of the presence or absence of multiple GC populations in colors in NGC 1395.

Nationwide people with disabilities are self-directing their long-term care supports through individual budgets. Because these individuals may rely on a "support broker" to assist them in making and executing decisions regarding their budgets, the interactions between the participant and the support broker can influence participant autonomy. Massachusetts piloted a program for 14 participants to receive individual budgets for home and community-based services. Central to this pilot were the participant-designated support brokers, including home care case managers and peer advocates. Analysis of data on participants and support brokers indicated that the support brokers struggled with when, how, and how much to assist participants to self-direct. Case managers or other providers assuming the support broker's role will need proper training if they are to respond skillfully to challenging situations self-direction may bring.

The objective of this study was to investigate knowledge, opinions, and attitudes toward, as well as readiness to accept genetically modified organisms (GMOs) among prospective primary and secondary Slovene teachers. Our findings are that prospective teachers want to take an active role in rejecting or supporting individual GMOs and are aware of the importance of education about genetically modified organism (GMO) items and their potential significance for society. Through cluster analysis, we recognized four clusters of GMOs, separated by degree of genetically modified acceptability. GM plants and microorganisms which are recognized as useful are accepted. They are undecided about organisms used in research or medicine and reject organisms used for food consumption and for fun. There are only weak correlations between knowledge and attitudes and knowledge and acceptance of GMOs, and a strong correlation between attitudes and acceptance. The appropriate strategies and actions for improving university courses in biotechnology are discussed. Copyright © 2010 International Union of Biochemistry and Molecular Biology, Inc.

Identification of the support needs of individuals with severe mental illness using the Supports Intensity Scale

Full Text Available OBJECTIVE: to characterize the intensity of the support needs of individuals with severe mental illness. METHODS: quantitative and descriptive study that applied the Supports Intensity Scale to a sample comprising 182 individuals. RESULTS: the supports intensity profile identifies groups, individuals, and areas with different needs of support relative to the domains of home living, health, community living, learning, employment, and social living. As a whole, the intensity level of support needs found was low, and the domains with greater needs were employment and social. CONCLUSIONS: identification of the intensity of support needs is helpful in planning integral care and detecting professional training needs. The support provision-centered approach, associated with the person-related outcomes perspective, has been sparsely applied to individuals with mental illness, and this represents the main contribution of the present study. In addition, this study introduces novel approaches to assessment that are both concordant and an innovation in nursing because they might provide a tool for understanding other disabilities.

The potential of technology to enhance delivery and outcomes of Individual Placement and Support (IPS) supported employment. IPS supported employment has demonstrated robust success for improving rates of competitive employment among individuals with psychiatric disabilities. Still, a majority of those with serious mental illnesses are not employed (Bond, Drake, & Becker, 2012). The need to promote awareness of IPS and expand services is urgent. In this study, we describe ways that technologies may enhance delivery of IPS supported employment across the care continuum and stakeholder groups. Directions for research are highlighted. published literature, clinical observations, IPS learning collaborative. Technology has the potential to enhance direct service as well as workflow in the IPS supported employment process, which may lead to improved fidelity and client outcomes. Mobile and cloud technologies open opportunities for collaboration, self-directed care, and ongoing support to help clients obtain and maintain meaningful employment. Research is needed to evaluate efficacy of technology-based approaches for promoting client employment outcomes, to identify provider and organization barriers to using technology for IPS delivery, and to determine effective strategies for implementing technology with IPS in different settings and with diverse client audiences.

Revealing the nebular properties and Wolf-Rayet population of IC10 with Gemini/GMOS

2017-12-01

We present a deep imaging and spectroscopic survey of the Local Group irregular galaxy IC10 using Gemini North and GMOS to unveil its global Wolf-Rayet (WR) population. We obtain a star formation rate (SFR) of 0.045 ± 0.023 M⊙ yr-1, for IC10 from the nebular H α luminosity, which is comparable to the Small Magellanic Cloud. We also present a revised nebular oxygen abundance of log(O/H) + 12 = 8.40 ± 0.04, comparable to the LMC. It has previously been suggested that for IC10 to follow the WR subtype-metallicity dependance seen in other Local Group galaxies, a large WN population awaits discovery. Our search revealed three new WN stars, and six candidates awaiting confirmation, providing little evidence to support this claim. The new global WR star total of 29 stars is consistent with the Large Magellanic Cloud population when scaled to the reduced SFR of IC10. For spectroscopically confirmed WR stars, the WC/WN ratio is lowered to 1.0; however, including all potential candidates, and assuming those unconfirmed to be WN stars, would reduce the ratio to ∼0.7. We attribute the high WC/WN ratio to the high star formation surface density of IC10 relative to the Magellanic Clouds, which enhances the frequency of high-mass stars capable of producing WC stars.

Individual Placement and Support is a vocational rehabilitation programme for people with severe mental illness, which was implemented during the period 2003-2005 at four locations in the Netherlands. To investigate the degree of compliance with the Individual Placement and Support programme, the factors that hindered or facilitated its implementation, and the results. The degree of compliance was assessed using the Individual Placement and Support fidelity scale. Data regarding the factors that hindered or facilitated the implementation were collected via interviews and monitoring. In addition, data were collected on patient characteristics, the support provided and the jobs found. None of the locations achieved the highest level of compliance, although two locations came close. Eighteen per cent of the 316 patients were helped to find a regular job. The most important obstacles to implementation were loss of vocational team members, project leaders' lack of time, lack of finance, and insufficient cooperation between the organisations involved. The most important facilitating factors were the skills and commitment of the vocational team member(s) and the integration of the vocational teammember(s) and the mental health team. It is not easy to implement Individual Placement and Support. However, if more attention is given to good project management, Individual Placement and Support can succeed in the Netherlands.

We present results from the first comprehensive survey program dedicated to probing transiting exoplanet atmospheres using transmission spectroscopy with a multi-object spectrograph (MOS). Our four-years survey focussed on ten close-in giant planets for which the wavelength dependent transit depths in the visible were measured with Gemini/GMOS. We present the complete analysis of all the targets observed (50 transits, 300 hours), and the challenges to overcome to achieve the best spectrophotometric precision (200-500 ppm / 10 nm). We also present the main results and conclusions from this survey. We show that the precision achieved by this survey permits to distinguish hazy atmospheres from cloud-free ones. We discuss the challenges faced by such an experiment, and the lessons learnt for future MOS survey. We lay out the challenges facing future ground based MOS transit surveys aiming for the atmospheric characterization of habitable worlds, and utilizing the next generation of multi-object spectrographs mounted on extremely large ground based telescopes (ELT, TMT).

Agriculture based on genetically modified organisms plays an increasingly important role in feeding the world population, which is evidenced by a considerable growth in the size of land under genetically modified crops (GM). Uncertainty and controversy around GM products are mainly due to the lack of accurate and reliable information, and lack of knowledge concerning the essence of genetic modifications, and the effect of GM food on the human organism, and consequently, a negative emotional attitude towards what is unknown. The objective of the presented study was to discover to what extent knowledge and the emotional attitude of adolescents towards genetically modified organisms is related with acceptance of growing genetically modified plants or breeding GM animals on own farm or allotment garden, and the purchase and consumption of GM food, as well as the use of GMOs in medicine. The study was conducted by the method of a diagnostic survey using a questionnaire designed by the author, which covered a group of 500 adolescents completing secondary school on the level of maturity examination. The collected material was subjected to statistical analysis. Research hypotheses were verified using chi-square test (χ 2 ), t-Student test, and stepwise regression analysis. Stepwise regression analysis showed that the readiness of adolescents to use genetically modified organisms as food or for the production of pharmaceuticals, the production of GM plants or animals on own farm, depends on an emotional-evaluative attitude towards GMOs, and the level of knowledge concerning the essence of genetic modifications.

The number of commercially available genetically modified organisms (GMOs) and therefore the diversity of possible target sequences for molecular detection techniques are constantly increasing. As a result, GMO laboratories and the food production industry currently are forced to apply many different methods to reliably test raw material and complex processed food products. Screening methods have become more and more relevant to minimize the analytical effort and to make a preselection for further analysis (e.g., specific identification or quantification of the GMO). A multiplex real-time PCR kit was developed to detect the 35S promoter of the cauliflower mosaic virus, the terminator of the nopaline synthase gene of Agrobacterium tumefaciens, the 35S promoter from the figwort mosaic virus, and the bar gene of the soil bacterium Streptomyces hygroscopicus as the most widely used sequences in GMOs. The kit contains a second assay for the detection of plant-derived DNA to control the quality of the often processed and refined sample material. Additionally, the plant-specific assay comprises a homologous internal amplification control for inhibition control. The determined limits of detection for the five assays were 10 target copies/reaction. No amplification products were observed with DNAs of 26 bacterial species, 25 yeasts, 13 molds, and 41 not genetically modified plants. The specificity of the assays was further demonstrated to be 100% by the specific amplification of DNA derived from reference material from 22 genetically modified crops. The applicability of the kit in routine laboratory use was verified by testing of 50 spiked and unspiked food products. The herein described kit represents a simple and sensitive GMO screening method for the reliable detection of multiple GMO-specific target sequences in a multiplex real-time PCR reaction.

Individual Placement and Support is the most defined and evidence-based approach to supported employment for severe mental illness, including recent-onset psychosis. However, there is limited evidence or detailed guidelines informing the management of mental illness disclosure to educators or employers when delivering individual placement and support. In this paper, we describe the initial disclosure preferences of young people with recent-onset psychosis enrolled in individual placement and support and provide guidance for managing disclosure when delivering Individual Placement and Support with this population. Drawing from sites in Melbourne, Australia and Los Angeles, USA, clients' initial disclosure preferences were examined. We describe approaches to providing individual placement and support when no disclosure is permitted compared with when disclosure is permitted, including two illustrative case vignettes. No disclosure of mental illness or disability was requested by 54-59% of clients; 41-46% of clients permitted partial or complete disclosure. The 'no disclosure' scenario required the individual placement and support worker to provide support 'behind the scenes', whereas when disclosure was permitted, the individual placement and support worker could have contact with instructors/employers and work 'on the front lines'. The case vignettes illustrate how both approaches can lead to successful vocational outcomes. We found that Individual Placement and Support can be provided in an educative, flexible, creative and collaborative manner according to client disclosure preferences. We suggest that disclosure preferences do not prevent successful vocational outcomes, although this supposition requires empirical investigation. © 2013 Wiley Publishing Asia Pty Ltd.

NGC 3393, a nearby Seyfert 2 galaxy with nuclear radio jets, large-scale and nuclear bars, and a posited secondary super massive black hole, provides an interesting laboratory to test the physics of inflows and outflows. Here we present and analyse the molecular gas (ALMA observations of CO J:2-1 emission over a field of view (FOV) of 45" × 45", at 0."56 (143 pc) spatial and 5 km/s spectral resolution), ionised gas and stars (GEMINI-GMOS/IFU; over a FOV of 4" × 5", at 0."62 (159 pc) spatial and 23 km/s spectral resolution) in NGC 3393. The ionised gas emission, detected over the complete GEMINI-GMOS FOV, has three identifiable kinematic components. A narrow (σ 115 km/s) redshifted component, detected near the NE and SW radio lobes; which we interpret as a radio jet driven outflow. And a broad (σ > 115 km/s) blueshifted component that shows high velocities in a region perpendicular to the radio jet axis; we interpret this as an equatorial outflow. The CO J:2-1 emission is detected in spiral arms on 5" - 20" scales, and in two disturbed circumnuclear regions. The molecular kinematics in the spiral arms can be explained by rotation. The highly disturbed kinematics of the inner region can be explained by perturbations induced by the nuclear bar and interactions with the large scale bar. We find no evidence for, but cannot strongly rule out, the presence of the posited secondary black hole.

Abstract Direct support professionals (DSPs) and frontline supervisors (FLSs) play an integral role in the lives of people with intellectual and developmental disabilities (IDD) and are often the individuals directly responsible for assisting people with IDD to live and fully participate in their communities. These two groups of workers have typically been employed at lower wages with limited access to fringe benefits, contributing to high rates of turnover compared to a similarly skilled worker in the United States. This article summarizes findings and is the first investigation in several years to systematically examine the wages, fringe benefits, and stability of the DSP and FLS workforces supporting individuals with IDD. Findings suggest that a typical DSP may expect to earn about $11.25 per hour, while FLSs may expect wages of about $15.45 hourly. Of concern, however, is that fringe benefit provision was quite limited in this sample. Implications, including relation to past reports of DSP workforce development, are discussed.

Full Text Available Biosafety of genetically modified organisms (GMOs and their derivatives is still a major topic in the agenda of government and societies worldwide. The aim of this review is to bring into light that data that supported the decision taken back in 1998 as an exercise to stimulate criticism from the scientific community for upcoming discussions and to avoid emotional and senseless arguments that could jeopardize future development in the field. It must be emphasized that Roundup Ready® soybean is just one example of how biotechnology can bring in significant advances for society, not only through increased productivity, but also with beneficial environmental impact, thereby allowing more rational use of agricultural pesticides for improvement of the soil conditions. The adoption of agricultural practices with higher yield will also allow better distribution of income among small farmers. New species of genetically modified plants will soon be available and society should be capable of making decisions in an objective and well-informed manner, through collegiate bodies that are qualified in all aspects of biosafety and environmental impact.A biosegurança dos organismos geneticamente modificados e seus derivados é um dos principais tópicos na agenda de discussões de governos e sociedades. O objetivo desta revisão é reviver os dados científicos que fundamentaram a decisão de liberação comercial da soja transgênica resistente ao Glifosate com o intuito de estimular uma posição crítica da comunidade científica para as próximas discussões no tema. A soja em questão é apenas um exemplo de como a biotecnologia pode contribuir para avanços na produtividade e na preservação do meio ambiente, com ganho de produtividade e lucratividade para agricultores em todas as escalas. Novas variedades trangênicas estarão na pauta de discussões que deverão estar fundamentadas em dados científicos objetivos, evitando argumentos emocionais que

Social support has been noted to improve health outcomes for individuals with HIV. Understanding how neighborhoods contribute to feelings of social support is beneficial to create environments where populations with HIV can be supported. This study assessed the relationship between neighborhood perceptions and social support with HIV management. A total of 201 individuals were recruited; individuals with HIV, 18 years or older, who were eligible to participate in the 2-hour interview. Psychiatric diagnostic interviews were conducted alongside assessments of social support and neighborhood perceptions; biomedical markers were abstracted from medical records. Correlations and linear regression analyses were performed to assess relationships between social support and neighborhood perceptions with HIV management biomarkers. The majority of the sample was male (68.8%) and African American (72.3%), with a mean age of 43.1 years. Overall, 78% were receiving combination antiretroviral therapy (cART) prescriptions, with 69% being virally suppressed. Fear of neighborhood activities was independently associated with receiving current cART. Reports of social support and neighborhood perceptions were highly correlated. Findings suggest that supportive home environments likely would improve perceptions of social support.

Organizations and nurse leaders do not always effectively support nurses' ethical competence. More information is needed about nurses' perceptions of this support and relevant factors to improve it. The aim of the study was to examine relationships between nurses' perceived organizational and individual support, ethical competence, ethical safety, and work satisfaction. A cross-sectional questionnaire survey was conducted. Questionnaires were distributed to nurses (n = 298) working in specialized, primary, or private health care in Finland. Descriptive statistics, multifactor analysis of variance, and linear regression analysis were used to test the relationships. The nurses reported low organizational and individual support for their ethical competence, whereas perceptions of their ethical competence, ethical safety, and work satisfaction were moderate. There were statistically significant positive correlations between both perceived individual and organizational support, and ethical competence, nurses' work satisfaction, and nurses' ethical safety. Organizational and individual support for nurses' ethical competence should be strengthened, at least in Finland, by providing more ethics education and addressing ethical problems in multiprofessional discussions. Findings confirm that organizational level support for ethical competence improves nurses' work satisfaction. They also show that individual level support improves nurses' sense of ethical safety, and both organizational and individual support strengthen nurses' ethical competence. These findings should assist nurse leaders to implement effective support practices to strengthen nurses' ethical competence, ethical safety, and work satisfaction.

Despite the prevalence of Internet support groups for individuals with mental illnesses little is known about the potential benefits, or harm, of participating in such groups. Therefore, this randomized controlled trial sought to determine the impact of unmoderated, unstructured Internet peer support, similar to what is naturally occurring on the Internet, on the well-being of individuals with psychiatric disabilities. Three hundred individuals resident in the USA diagnosed with a Schizophrenia Spectrum or an Affective Disorder were randomized into one of three conditions: experimental Internet peer support via a listserv, experimental Internet peer support via a bulletin board, or a control condition. Three measurement time points, baseline, 4- and 12 months post-baseline, assessed well-being by examining measures of recovery, quality of life, empowerment, social support, and distress. Time × group interactions in the repeated measures ANOVA showed no differences between conditions on the main outcomes. Post-hoc repeated measures ANOVAs found that those individuals who participated more in Internet peer support reported higher levels of distress than those with less or no participation (p = 0.03). Those who reported more positive experiences with the Internet peer support group also reported higher levels of psychological distress than those reporting less positive experiences (p = 0.01). Study results therefore do not support the hypothesis that participation in an unmoderated, unstructured Internet listserv or bulletin board peer support group for individuals with psychiatric disabilities enhances well-being. Counterintuitive findings demonstrating those who report more positive experiences also experienced higher levels of distress are discussed but we also point to the need for additional research. Future research should explore the various structures, formats, and interventions of Internet support, as well as the content and quality of interactions

Full Text Available Abstract Background Debates persist around the world over the development and use of genetically modified organisms (GMO. News media has been shown to both reflect and influence public perceptions of health and science related debates, as well as policy development. To better understand the news coverage of GMOs in China, we analyzed the content of articles in two Chinese newspapers that relate to the development and promotion of genetically modified technologies and GMOs. Methods Searching in the Chinese National Knowledge Infrastructure Core Newspaper Database (CNKI-CND, we collected 77 articles, including news reports, comments and notes, published between January 2002 and August 2011 in two of the major Chinese newspapers: People’s Daily and Guangming Daily. We examined articles for perspectives that were discussed and/or mentioned regarding GMOs, the risks and benefits of GMOs, and the tone of news articles. Results The newspaper articles reported on 29 different kinds of GMOs. Compared with the possible risks, the benefits of GMOs were much more frequently discussed in the articles. 48.1% of articles were largely supportive of the GM technology research and development programs and the adoption of GM cottons, while 51.9% of articles were neutral on the subject of GMOs. Risks associated with GMOs were mentioned in the newspaper articles, but none of the articles expressed negative tones in regards to GMOs. Conclusion This study demonstrates that the Chinese print media is largely supportive of GMOs. It also indicates that the print media describes the Chinese government as actively pursuing national GMO research and development programs and the promotion of GM cotton usage. So far, discussion of the risks associated with GMOs is minimal in the news reports. The media, scientists, and the government should work together to ensure that science communication is accurate and balanced.

Nurses' ethical competence has been identified as a significant factor governing high quality of care. However, nurses lack support in dealing with ethical problems, and therefore managerial support for nurses' ethical competence is needed. This study aimed to analyse, from the perspective of nurse and nurse leaders, the level of nurses' and nurse leaders' ethical competence, perceptions of support for nurses' ethical competence at the organisational and individual levels and background factors associated with this support. A descriptive, cross-sectional study design was employed. The Ethical Competence and Ethical Competence Support questionnaires were used to measure the main components. Descriptive statistics and multifactor analysis of variance were used for data analysis. The participants were 298 nurses and 193 nurse leaders working in specialised (48%/52%), primary (43%/36%) or private healthcare (5%/7%) in Finland. Ethical considerations: Ethical approval was obtained from the university ethics committee. Nurses estimated their own ethical competence to be at an average level, whereas nurse leaders estimated their own competence at a high level. Nurses' and nurse leaders' perceptions of provided support for nurses' ethical competence was not at a high level. The positive agreement percentage related to organisational support was 44% among nurses and 51% among nurse leaders. The positive agreement percentage related to individual support was lower, that is, 38% among nurses and 61% among nurse leaders. University education had a positive association with some items of individual support. Despite the findings that ethical competence was estimated at a high level among nurse leaders, perceptions of support for nurses' ethical competence were not at a satisfactory level. At the organisational level, nurse leaders need to inform of ethical procedures and practices in orientation; encourage multidisciplinary ethics discussions and collaboration; and support

Currently, the detection methods with lower cost and higher throughput are the major trend in screening genetically modified (GM) food or feed before specific identification. In this study, we developed a quadruplex degenerate PCR screening approach for more than 90 approved GMO events. This assay is consisted of four PCR systems targeting on nine DNA sequences from eight trait genes widely introduced into GMOs, such as CP4-EPSPS derived from Acetobacterium tumefaciens sp. strain CP4, phosphinothricin acetyltransferase gene derived from Streptomyceshygroscopicus (bar) and Streptomyces viridochromogenes (pat), and Cry1Ab, Cry1Ac, Cry1A(b/c), mCry3A, and Cry3Bb1 derived from Bacillus thuringiensis. The quadruplex degenerate PCR assay offers high specificity and sensitivity with the absolute limit of detection (LOD) of approximate 80targetcopies. Furthermore, the applicability of the quadruplex PCR assay was confirmed by screening either several artificially prepared samples or samples of Grain Inspection, Packers and Stockyards Administration (GIPSA) proficiency program.

Full Text Available Provided with the contributions of the linguistic turn, our perspective conceives political theorizing as an intervention of the researcher in an intersubjective context in which a public issue is debated. We focus on those contexts in which the exercise and claim for rights against the consequences of agribusiness is thematized: diseases and deaths, siteclearances and evictions of indigenous and peasant communities, omission or complicit actions of the state institutions among other issues. We consider these diverse and sustained over time practices as struggles for recognition that put in tension the complacent “consensus of the commodities”, its concepts, practices, institutions and effects. We present the struggles against the pillars of agribusiness in Argentina: GMOs, pesticides and the National Commission on Agricultural Biotechnology (CONABIA. As a result of our research there are contributions that uncover the web of relationships impacted by agribusiness, the public problems generated and currently generates the technological innovation in this field, and the limits and possibilities for resolution. Also we offer glimpse into the structure, criteria and operation, also made invisible: the body of the official political system with responsibilities in this case in our country, the National Commission for Agricultural Technology (CONABIA.

To understand the relationship of individual characteristics, perceived worksite support and perceived personal creativity to clinical nurses' innovative outcome (receiving the Nursing Innovation Award). Since the idea of applying creativity and innovation to clinical nursing practice and management was first advocated in the Nursing Administration Quarterly in 1982, the topic of nursing innovation has gained worldwide attention. To increase the prevalence of nursing innovation, it is important to identify and understand the related factors that influence nurses' innovative outcome. This study used a cross-sectional descriptive survey design. A self-administered questionnaire was completed by 32 award winners and 506 nonawarded clinical nurses in Taiwan. The level of creativity perceived by all participants was moderate-to-high. Individual characteristics (r = 0·61) and worksite support (r = 0·27) were both correlated with perceived creativity. Individual characteristics and worksite support showed some correlation as well (r = 0·21). Individual characteristics and worksite support could predict perceived creativity after controlling for demographic variables, but only individual characteristics had an effect on innovative outcome. Perceived creativity did not have mediation effects either between individual characteristics and innovative outcome or between worksite support and innovative outcome. Clinical nurses' individual characteristics had a direct relationship to innovative outcome, whereas neither worksite support nor creativity was correlated with innovative outcome. Although worksite support did not show effects on innovative outcome, it was related to both perceived creativity and individual characteristics. As suggested by other scholars, there might be other related factors between creativity and innovative outcome. Although worksite support did not have effect on clinical nurses' innovative outcome, it was related to individual characteristics

Of particular interest is a combination of traditional and computer-aided tutor support for individualized learning approaches based on the specific means of mapping.A tutor is an intermediary between a student (pupil and a teacher or between a student and a knowledge source in case of self-learning to orient the educational process to the student's personal goals and implement the L.

Thus, the tutor faces a task to identify the personal learning goals, disclose the learning prospects and its supports, but the student plays a role of a decision-maker. One of the nuclear problems of tutorage is making an individual educational or didactic path, which expects making a kind of distinctive cognition route.An application of cognitive visualization as a tutor's tools, is aimed, primarily, at a comprehensive representation of subjective educational student's space. A student has to be oriented inside this space to reach the denoted goals. In this context it is possible to formulate the navigation problem, which may be solved it in the most rational way by educational space mapping and navigating in it at any moment of the educational process. All three basic qualities of maps (the presence of different spatial objects in the corresponding metric, vector and scale can be usefully applied to support an individualized learning process.The paper shows that personality-resource maps can be used for describing the learning situation and building an individual study program in graphical form when the specifics of direct individualized learning is taken into account.

Supervisor emotional support is a strong determinant of job satisfaction. There is no study examining the effect of supervisor emotional support at the group level on job satisfaction. Multilevel statistical techniques can help disentangle the effects of subjective assessments from those of group factors. The study's aim was to examine the moderating role of supervisor emotional support (group-level variable) on the relationship between work engagement and job satisfaction (individual-level variables). A cross-sectional study was performed in 39units from three Belgian hospitals. A total of 323 nurses completed a self-reported questionnaire. We carried out a multilevel analysis by using Hierarchical Linear Modeling. The results showed that the cross-level interaction was significant. Hence, at individual-level, the nurses with high levels of work engagement showed high levels of job satisfaction and this relationship was stronger when supervisor emotional support at group-level was high. Contextual differences among groups had an impact on the form of the work engagement-job satisfaction relationship. This relationship between work engagement and job satisfaction is an individual and group level phenomenon. Ways to enhance emotional supervisor support include training supervisors in providing support and enhancing communication between nurses and supervisors. Copyright © 2016 Elsevier Inc.

2016-10-01

Full Text Available Background Divorce is a transition period in which divorcing individuals face restructuring of the family system and adjustment to changes. The psychological well-being of divorcees can serve as an important indicator of the adjustment process. The achievement of well-being does not come easily for many reasons, one of which is the experience related to a sense of loss associated with the marriage break-up. Social support is a major relational resource for overcoming the crisis and successfully adjusting to post-divorce life. Participants and procedure The sample consisted of 157 individuals after divorce: 120 women and 37 men (mean age = 41.29. Instruments employed in the study included the Sense of Loss Scale (DS, the Interpersonal Support Evaluation List (ISEL, the Oxford Happiness Questionnaire (OHQ-23, and sociodemographic data. Results Our results show that perceived social support is a partial mediator of the relationship between the sense of loss associated with divorce and the psychological well-being of individuals after divorce. For the vast majority of the respondents their parents, friends and acquaintances were the major source of support. About one third of the participants were given support by their siblings and their own children. Conclusions The study confirms the mediating role of support in building well-being after experiencing loss related to dissolution of marriage. This means that for divorced women and men perceived social support is one of the key resources that have a significant impact on achieving psychological well-being after divorce, since it is related to mitigating the negative impact of the sense of loss associated with marriage break-up.

[Resilience in Individuals with Gender Dysphoria: Association with Perceived Social Support and Discrimination].

Psychological distress associated with discrimination is proposed to have an indirect effect on the development of mental disorders, through its negative influence on individual's cognitive, affective and social coping strategies. The aim of this study was to investigate the association between resilience, perceived social support, and perceived discrimination in individuals with gender dysphoria. Individuals with gender dysphoria were assessed with Turkish validated forms of Resilience Scale for Adults (RSA), Multidimensional Scale of Perceived Social Support (MSPSS), Perceived Discrimination Scale (PDS), and Beck Depression Inventory (BDI). Diagnoses of mental disorders, history of suicide attempt and non-suicidal self injury were assessed with clinical interviews. Self-report forms were used to obtain demographic information and gender transition related features. Participants' (n=116, 88 trans men) median age was 25. Significantly low RSA scores, indicating poor resilience, were obtained in participants with lifetime (59.5 %) and present (27.6 %) diagnosis of any mental disorder, history of suicide attempt (23.3 %). There was significant direct correlation between RSA and MSPSS scores, inverse correlation with BDI and personal PDS scores, but not with group PDS. Regression analysis revealed that only friends domain score in MSPSS predicted better resilience, whereas personal perceived discrimination score predicted poor resilience. Findings support the association between poor resilience and vulnerability to mental and behavioral problems in individuals with gender dysphoria. The associations reveal the significance of addressing discrimination and assisting individuals with gender dysphoria in developing strategies to obtain peer support in providing mental health services.

The individual placement and support (IPS) model of supported employment was first developed in community mental health centres for adults with severe mental illness. While IPS is an established evidence-based practice in this broad population, evidence on its effectiveness focused specifically on young adults has been limited. The current study aimed to address this gap. To investigate the effects of IPS on young adults, the authors conducted a secondary analysis on a pooled sample of 109 unemployed young adults (under age 30) from four randomized controlled trials employing a common research protocol that included a standardized measurement battery and rigorous fidelity monitoring. Researchers assessed these participants over 18 months on nine competitive employment outcome measures. On all measures, the IPS group had significantly better employment outcomes. Overall, 40 (82%) of IPS participants obtained employment during follow-up compared with 25 (42%) of control participants, χ(2) = 17.9, P < .001. IPS participants averaged 25.0 weeks of employment, compared with 7.0 weeks for control participants, t = 4.50, P < .001. The current analysis supports a small number of previous studies in showing that IPS is highly effective in helping young adults with severe mental illness to attain competitive employment. When young adults acquire competitive jobs and initiate a path towards normal adult roles, they may avoid the cycle of disability and psychiatric patient roles that are demeaning and demoralizing. © 2014 Wiley Publishing Asia Pty Ltd.

Longitudinal relationships between individual and class norms supporting dating violence and perpetration of dating violence.

2015-03-01

Dating violence is commonly perpetrated in adolescence, making it imperative to understand risk factors in order to inform prevention efforts. Although individual norms supporting dating violence are strongly related to its perpetration, few studies have examined their longitudinal impact. Moreover, the influence of class norms (i.e., norms for students in the same grade, cohort, and school) supporting dating violence on perpetration has rarely been studied. The current study examined longitudinal relationships between individual and class norms supporting dating violence and perpetration of physical and psychological dating violence. Participants were two cohorts of sixth graders from 37 schools who were in dating relationships at Wave 1 and 6 months later at Wave 2 (N = 2,022; 43% female; 52% African American, 21% Latino/a, 20% White, and 7% other). The analyses used a multilevel approach, with students represented at Level 1 and classes (n = 74) at Level 2. The models tested direct effects of Wave 1 individual and class norms supporting dating violence on subsequent changes in perpetration of dating violence at Wave 2 and the extent to which gender moderated these relationships. The findings indicated that greater individual norms supporting male dating violence predicted greater change in perpetration of physical and psychological dating violence and greater individual norms supporting female dating violence predicted greater change in perpetration of psychological dating violence. Greater class norms supporting male dating violence predicted greater change in perpetration of physical dating violence; whereas greater class norms supporting female dating violence predicted less change in perpetration of physical dating violence. These findings highlight the need to address norms in early adolescence.

Full Text Available Introduction: Psychological hardiness is a personal factor and social support is regarded as an environmental factor that can facilitate adjustment to disease. This study aimed to investigate the relationship between adaptation with psychological hardiness and social support in individuals with Multiple sclerosis (MS. Methods: Seventy two females with MS and 25 males with MSwere selected through randomized sampling from two MS centers. Main variables of the study including adaptation, psychological hardiness, and social supportwere assessed respectively by Adaptation Inventory, Personal Attitudes Survey, and Social Support Questionnaire. Results: Spearman correlation coefficients revealed that there are significant relationships between adaptation and psychological hardiness (p<0.0001, as well as between adaptation and social support (p<0.0001. In addition, Multiple linear Regression showed that psychological hardiness (β= -0.483 and social support (β= -0.240 can explain 35/1% of adaptation variance in individuals with MS. Psychological hardinessproved to have a more important role in adaptation of individuals with MS. Conclusion: The study data demonstrated that personal factors like psychological hardiness and environmental factors such as social support can predict adjustment in individuals with MS. In order to clarify mechanisms of these factors on adaptation in individuals with MS, morelongitudinal and experimental studiesare required. These results are alsoapplicable in designing therapeutic programs for individuals with MS.

Full Text Available The paper focuses on the issues of social support of individuals with disabilities and describes its role in the development and maintenance of subjective well-being of persons in situations of disability. A special external resource for overcoming unfavorable developmental conditions, social support is interlocked in a continuous relationship with psychological resources of personality. One of its distinctive features is that it implies the subject's activity aimed at overcoming difficult life situation on his/her own. When the person's bodily resources are insufficient (as it happens in situations of physical disabilities, the role of macro- and microsocial resources in supporting his/her well-being naturally increases. However, when both social and bodily resources are scarce, it is the individual's personality that stands in the gap. The research described in the paper explored the relationship between microsocial resources (support of family and friends, satisfaction with this support and psychological resources of resistance and self-regulation of personality. The sample consisted of 210 subjects (48 students with disabilities, 162 healthy subjects. The outcomes revealed certain differences between the subsamples with low and high rates of social support which suggest that the subjects' perceptions and evaluations of the support contribute to their psychological resources of coping and self-regulation, activating and/or reinforcing the existing potential of their personalities.

Individuals with mental health problems have many support needs that are often inadequately met; however, perceptions of who should be responsible for meeting these needs have been largely unexplored. Varying perceptions may influence whether, how, and to what extent relevant stakeholders support individuals with mental health problems. To critically evaluate the literature to determine who different stakeholders believe should be responsible for supporting individuals with mental health problems, what factors shape these perceptions, and how they relate to one another. A critical literature review was undertaken. Following an extensive literature search, the conceptual contributions of relevant works were critically evaluated. A concept map was created to build a conceptual framework of the topic. Views of individual versus societal responsibility for need provision and health; the morality of caring; and attributions of responsibility for mental illness offered valuable understandings of the review questions. Creating a concept map revealed that various interrelated factors may influence perceptions of responsibility. Varying perceptions of who should be responsible for supporting individuals with mental health problems may contribute to unmet support needs among this group. Our critical review helps build a much-needed conceptual framework of factors influencing perceptions of responsibility. Such a framework is essential as these views iteratively shape and reflect the complex divisions of mental healthcare roles and responsibilities. Understanding these perceptions can help define relevant stakeholders' roles more clearly, which can improve mental health services and strengthen stakeholder accountability.

Loughery, Joanne; Woodgate, Roberta L

2015-01-01

Regardless of geographic location, the cancer journey is an extremely difficult experience for both patients and their families. The aim of this literature review is to explore the impact of rural or remote residence on the supportive care needs of individuals living with cancer. This review included ten qualitative, seven quantitative, and six mixed design studies. Data collection, analysis, and evaluation were guided using a multi-domain supportive care framework based on seven domains: physical, emotional, informational, psychological, spiritual, social, and practical (Fitch, 2009). This review will suggest that there are distinct experiences that present both challenges and benefits to individuals living with cancer in rural areas. These findings will be detailed with recommendations, and grounding for future research outlined.

In this paper, DNA extraction methods have been evaluated to detect the presence of genetically modified organisms (GMOs) in maize food and feed products commercialised in Turkey. All the extraction methods tested performed well for the majority of maize foods and feed products analysed. However, the highest DNA content was achieved by the Wizard, Genespin or the CTAB method, all of which produced optimal DNA yield and purity for different maize food and feed products. The samples were then screened for the presence of GM elements, along with certified reference materials. Of the food and feed samples, 8 % tested positive for the presence of one GM element (NOS terminator), of which half (4 % of the total) also contained a second element (the Cauliflower Mosaic Virus 35S promoter). The results obtained herein clearly demonstrate the presence of GM maize in the Turkish market, and that the Foodproof GMO Screening Kit provides reliable screening of maize food and feed products.

We present an observational study of the impacts of interactions on the stellar population in a sample of galaxy pairs. Long-slit spectra in the wavelength range 3440-7300 Å obtained with the Gemini Multi-Object Spectrograph (GMOS) at Gemini South for 15 galaxies in nine close pairs were used. The spatial distributions of the stellar population contributions were obtained using the stellar population synthesis code starlight. Taking into account the different contributions to the emitted light, we found that most of the galaxies in our sample are dominated by young/intermediate stellar populations. This result differs from the one derived for isolated galaxies, where the old stellar population dominates the disc surface brightness. We interpreted such different behaviour as being due to the effect of gas inflows along the discs of interacting galaxies on the star formation over a time-scale of the order of about 2 Gyr. We also found that, in general, the secondary galaxy of a pair has a higher contribution from the young stellar population than the primary one. We compared the estimated values of stellar and nebular extinction derived from the synthesis method and the Hα/Hβ emission-line ratio, finding that nebular extinctions are systematically higher than stellar ones by about a factor of 2. We did not find any correlation between nebular and stellar metallicities. Neither did we find a correlation between stellar metallicities and ages, while a positive correlation between nebular metallicities and stellar ages was obtained, with older regions being the most metal-rich.

The Emergence of Family-specific Support Constructs: Cross-level Effects of Family-supportive Supervision and Family-Supportive Organization Perceptions on Individual Outcomes.

Hill, Rachel T; Matthews, Russell A; Walsh, Benjamin M

2016-12-01

Implicit to the definitions of both family-supportive supervision (FSS) and family-supportive organization perceptions (FSOP) is the argument that these constructs may manifest at a higher (e.g. group or organizational) level. In line with these conceptualizations, grounded in tenants of conservation of resources theory, we argue that FSS and FSOP, as universal resources, are emergent constructs at the organizational level, which have cross-level effects on work-family conflict and turnover intentions. To test our theoretically derived hypotheses, a multilevel model was examined in which FSS and FSOP at the unit level predict individual work-to-family conflict, which in turn predicts turnover intentions. Our hypothesized model was generally supported. Collectively, our results point to FSOP serving as an explanatory mechanism of the effects that mutual perceptions of FSS have on individual experiences of work-to-family conflict and turnover intentions. Lagged (i.e. overtime) cross-level effects of the model were also confirmed in supplementary analyses. Our results extend our theoretical understanding of FSS and FSOP by demonstrating the utility of conceptualizing them as universal resources, opening up a variety of avenues for future research.

The Three-Dimensional Structure of HH 32 from GMOS IFU Spectroscopy

Beck, Tracy L.; Riera, A.; Raga, A. C.; Aspin, C.

2004-01-01

We present new high-resolution spectroscopic observations of the Herbig-Haro object HH 32 from system verification observations made with the GMOS IFU at Gemini North Observatory. The three-dimensional spectral data cover a 8.7"×5.85" spatial field and 4820-7040 Å spectral region centered on the HH 32 A knot complex. We show the position-dependent line profiles and radial velocity channel maps of the Hα line, as well as line ratio velocity channel maps of [O III] λ5007/Hα, [O I] λ6300/Hα, [N II] λ6583/Hα, [S II] λλ(6716+6730)/Hα, and [S II] λ6716/λ6730. We find that the line emission and the line ratios vary significantly on spatial scales of ~1" and over velocities of ~50 km s-1. A ``3/2-dimensional'' bow shock model is qualitatively successful at reproducing the general features of the radial velocity channel maps, but it does not show the same complexity as the data, and it fails to reproduce the line ratios in our high spatial resolution maps. The observations of HH 32 A show two or three superposed bow shocks with separations of ~3", which we interpret as evidence of a line-of-sight superposition of two or three working surfaces located along the redshifted body of the HH 32 outflow.

Can trust in politicians explain individuals' support for climate policy? The case of CO2 tax

International Nuclear Information System (INIS)

Hammar, Henrik; Jagers, Sverker C.

2006-01-01

This article provides an analysis of the support for public policies from a trust perspective. The empirical focus is on the use of a tax on carbon dioxide (CO 2 ), a policy tool aimed at coordinating national emissions targets in Sweden. Among economists and experts in the field of climate policy, a CO 2 tax is viewed as a cost-effective policy. The policy problem is that public support for CO 2 taxes is very low, leaving policy makers with high-cost options. Apart from traditional explanatory variables such as demographic factors, level of education, ideology and self-interest, what can explain this public opposition? Using individual level data, we analyse whether support for increases in the CO 2 tax on gasoline can be explained by citizens' generalized trust in other individuals (who they do not necessarily know) or by their trust in politicians. We find that only the latter measure gains support in a regression analysis. Moreover, when splitting the sample into high-trusting and low-trusting individuals, we find that high-trusting individuals who have access to a car (compared with those without access) are statistically no more likely to resist increases in CO 2 taxes than people without access to a car. Rather, it is individuals with access to a car and who do not trust their politicians who are likely to resist CO 2 taxes. (Author)

A model of individualized canonical microcircuits supporting cognitive operations.

Directory of Open Access Journals (Sweden)

Tim Kunze

Full Text Available Major cognitive functions such as language, memory, and decision-making are thought to rely on distributed networks of a large number of basic elements, called canonical microcircuits. In this theoretical study we propose a novel canonical microcircuit model and find that it supports two basic computational operations: a gating mechanism and working memory. By means of bifurcation analysis we systematically investigate the dynamical behavior of the canonical microcircuit with respect to parameters that govern the local network balance, that is, the relationship between excitation and inhibition, and key intrinsic feedback architectures of canonical microcircuits. We relate the local behavior of the canonical microcircuit to cognitive processing and demonstrate how a network of interacting canonical microcircuits enables the establishment of spatiotemporal sequences in the context of syntax parsing during sentence comprehension. This study provides a framework for using individualized canonical microcircuits for the construction of biologically realistic networks supporting cognitive operations.

To evaluate the impact of a community-based peer support program for individuals and their family members following traumatic brain injury (TBI). Community-based sample of family members and individuals with traumatic brain injury. Twenty individuals who had participated in the peer support program (11 individuals with TBI and 9 family members). Quantitative and qualitative approaches were used: a retrospective structured interview assessing self-reported impacts of peer support on empowerment, quality of life, mood, skills and knowledge, and social supports; an in-depth qualitative interview with a subgroup of family members focused on the specific benefits/limitations of the peer support program. Participants in the peer support program reported positive impacts of peer support on increasing their knowledge of TBI, enhancing their overall quality of life, improving their general outlook, and enhancing their ability to cope with depression post TBI. The peer support program was reported to have had a minimal impact on enhancing social support from families, friends, and the community, with varying impacts noted on levels of happiness, coping with anger and anxiety, communication with professionals, and control over one's life. Qualitative analysis suggests the merits of this type of community-based support and areas of improvement for the peer support program itself. Preliminary data suggest that peer support is a promising approach to enhancing coping for both individuals and their family members after TBI.

To identify unauthorised GMOs in food and feed matrices, an integrated approach has recently been developed targeting pCAMBIA family vectors, highly present in transgenic plants. Their presence is first assessed by qPCR screening and is subsequently confirmed by characterising the transgene flanking regions, using DNA walking. Here, the DNA walking performance has been thoroughly tested for the first time, regarding the targeted DNA quality and quantity. Several assays, on model food matrices mimicking common rice products, have allowed to determine the limit of detection as well as the potential effects of food mixture and processing. This detection system allows the identification of transgenic insertions as low as 10 HGEs and was not affected by the presence of untargeted DNA. Moreover, despite the clear impact of food processing on DNA quality, this method was able to cope with degraded DNA. Given its specificity, sensitivity, reliability, applicability and practicability, the proposed approach is a key detection tool, easily implementable in enforcement laboratories.

Increasingly, people with diverse health conditions turn to social media to share their illness experiences or seek advice from others with similar health concerns. This unstructured medium may represent a platform on which individuals with severe mental illness naturally provide and receive peer support. Peer support includes a system of mutual giving and receiving where individuals with severe mental illness can offer hope, companionship, and encouragement to others facing similar challenges. In this study we explore the phenomenon of individuals with severe mental illness uploading videos to YouTube, and posting and responding to comments as a form of naturally occurring peer support. We also consider the potential risks and benefits of self-disclosure and interacting with others on YouTube. To address these questions, we used qualitative inquiry informed by emerging techniques in online ethnography. We analyzed n = 3,044 comments posted to 19 videos uploaded by individuals who self-identified as having schizophrenia, schizoaffective disorder, or bipolar disorder. We found peer support across four themes: minimizing a sense of isolation and providing hope; finding support through peer exchange and reciprocity; sharing strategies for coping with day-to-day challenges of severe mental illness; and learning from shared experiences of medication use and seeking mental health care. These broad themes are consistent with accepted notions of peer support in severe mental illness as a voluntary process aimed at inclusion and mutual advancement through shared experience and developing a sense of community. Our data suggest that the lack of anonymity and associated risks of being identified as an individual with severe mental illness on YouTube seem to be overlooked by those who posted comments or uploaded videos. Whether or not this platform can provide benefits for a wider community of individuals with severe mental illness remains uncertain. PMID:25333470

Full Text Available This study aims to investigate clients’ satisfaction with Individual Placement and Support (IPS at the University Hospital for Psychiatry Zurich (PUK. Furthermore this study aims to investigate if clients feel the approach of IPS as a useful approach to fulfill their needs. 125 people were recruited from one of the three IPS services of PUK and were asked to complete a structured questionnaire. The following IPS services were available: i randomized controlled trial ZHEPP (www.zhepp.ch, ii randomized controlled trial ZInEP (www.zinep.ch and iii us clinical SE service of PUK (IPS-PUK. The clients mostly indicated that the IPS was generally useful and fitted their needs. Overall satisfaction of the participants with the IPS services of PUK was very high. Furthermore, this study confirms that client satisfaction and symptom severity are associated. In conclusion, participants of the IPS services received the support they were looking for. This means that the approach of IPS fits the needs of different patient groups and can be used without any modifications. The most important limitation is the unequal group sizes. Therefore, the obtained results need to be strengthen by future research.

Seeing GMOs from a Systems Perspective: The Need for Comparative Cartographies of Agri/Cultures for Sustainability Assessment

Directory of Open Access Journals (Sweden)

Amaranta Herrero

2015-08-01

Full Text Available Over the past twenty years, agricultural biotechnologies have generated chronically unresolved political controversies. The standard tool of risk assessment has proven to be highly limited in its ability to address the panoply of concerns that exist about these hybrid techno/organisms. It has also failed to account for both the conceptual and material networks of relations agricultural biotechnologies require, create and/or perform. This paper takes as a starting point that agricultural biotechnologies cannot be usefully assessed as isolated technological entities but need to be evaluated within the context of the broader socio-ecological system that they embody and engender. The paper then explores, compares and contrasts some of the methodological tools available for advancing this systems-based perspective. The article concludes by outlining a new synthesis approach of comparative cartographies of agri/cultures generated through multi-sited ethnographic case-studies, which is proposed as a way to generate system maps and enable the comparison of genetically modified (GM food with both conventional and alternative agri-food networks for sustainability assessment. The paper aims to make a unique theoretical and methodological contribution by advancing a systems-based approach to conceptualising and assessing genetically modified organisms (GMOs and proposing a synthesised methodology for mapping networks of relations across different agri/cultures.

The aim of this study was to investigate the relationship between the average HIV infection duration and the level of quantitatively rated post-traumatic stress disorder (PTSD) symptoms and social support dimensions in a sample of 562 Polish HIV+ adults. Possible moderating effects of social support on the relationship between the average HIV infection duration and the level of PTSD symptoms were also analysed. The results of this study suggest that the average HIV infection duration may intensify PTSD symptoms and deteriorate the perceived availability of social support in HIV+ individuals. However, a positive relationship between HIV infection duration and the level of trauma symptoms was observed only in the group of HIV+ individuals with low perceived available social support, but not in the group of HIV-infected individuals with high perceived available social support. This research provided some new insight into the psychological and social aspects of living with HIV. In particular, our results suggest that although HIV infection duration may intensify trauma symptoms and deteriorate social support, perceived available social support may act as a buffer against HIV-related trauma symptoms.

The Value of Caregiver Time: Costs of Support and Care for Individuals Living with Autism Spectrum Disorder

Directory of Open Access Journals (Sweden)

Carolyn Dudley

2014-01-01

Full Text Available When a child is diagnosed with autism spectrum disorder, the significance of the impact that diagnosis can have on his or her family’s life is incalculable, except in one respect: cost. If that child is severely impacted and requires constant and lifelong supports, then the value of caregiver time required to support that individual is approximately $5.5 million higher than that for someone without autism. An autism diagnosis of a high-needs child at age two represents the equivalent of telling the family that they must make an immediate lump-sum investment on that day of $1.6 million, invested at a five-per-cent return, to pay for the lifetime costs of care and support their loved one will require. And that amount does not even account for added professional services, such as speech therapists, psychologists, and occupational therapists, or additional out-of-pocket expenses that may be required, such as special equipment or diets. Autism is the most common neurological condition diagnosed in children and it is now estimated that one in 88 children will be diagnosed with autism spectrum disorders. Yet, across Canada, there are significant gaps in the publicly provided support system, leaving the cost burden to be picked up by families. In the case of those individuals requiring constant support, 24 hours a day, every day, the cost of hiring caregivers alone would require an annual income of $200,000 — before a family even begins to pay for shelter, clothing, groceries and other basic necessities. Already families with severe high-needs children are more likely to experience lower income than they might otherwise, due to the extra care commitment their loved one requires. Only a very few families will have the means to afford to pay for total care. So, in most cases, the responsibility for care falls largely, if not entirely, on the family, or in a worst-case scenario, the autistic individual is left with inadequate care. Autism is an

The velocity distribution of galaxies in clusters is not universal; rather, galaxies are segregated according to their spectral type and relative luminosity. We examine the velocity distributions of different populations of galaxies within 89 Sunyaev Zel’dovich (SZ) selected galaxy clusters spanning 0.28GMOS spectroscopic survey, supplemented by additional published spectroscopy, resulting in a final spectroscopic sample of 4148 galaxy spectra—2868 cluster members. The velocity dispersion of star-forming cluster galaxies is 17 ± 4% greater than that of passive cluster galaxies, and the velocity dispersion of bright (m< {m}* -0.5) cluster galaxies is 11 ± 4% lower than the velocity dispersion of our total member population. We find good agreement with simulations regarding the shape of the relationship between the measured velocity dispersion and the fraction of passive versus star-forming galaxies used to measure it, but we find a small offset between this relationship as measured in data and simulations, which suggests that our dispersions are systematically low by as much as 3% relative to simulations. We argue that this offset could be interpreted as a measurement of the effective velocity bias that describes the ratio of our observed velocity dispersions and the intrinsic velocity dispersion of dark matter particles in a published simulation result. Measuring velocity bias in this way suggests that large spectroscopic surveys can improve dispersion-based mass-observable scaling relations for cosmology even in the face of velocity biases, by quantifying and ultimately calibrating them out.

When cooperation begets cooperation: the role of key individuals in galvanizing support.

Life abounds with examples of conspecifics actively cooperating to a common end, despite conflicts of interest being expected concerning how much each individual should contribute. Mathematical models typically find that such conflict can be resolved by partial-response strategies, leading investors to contribute relatively equitably. Using a case study approach, we show that such model expectations can be contradicted in at least four disparate contexts: (i) bi-parental care; (ii) cooperative breeding; (iii) cooperative hunting; and (iv) human cooperation. We highlight that: (a) marked variation in contributions is commonplace; and (b) individuals can often respond positively rather than negatively to the contributions of others. Existing models have surprisingly limited power in explaining these phenomena. Here, we propose that, although among-individual variation in cooperative contributions will be influenced by differential costs and benefits, there is likely to be a strong genetic or epigenetic component. We then suggest that selection can maintain high investors (key individuals) when their contributions promote support by increasing the benefits and/or reducing the costs for others. Our intentions are to raise awareness in--and provide testable hypotheses of--two of the most poorly understood, yet integral, questions regarding cooperative ventures: why do individuals vary in their contributions and when does cooperation beget cooperation? © 2015 The Author(s).

Food insecurity, depression, and social support in HIV-infected Hispanic individuals.

Kapulsky, Leonid; Tang, Alice M; Forrester, Janet E

2015-04-01

Previous research has identified an association between food insecurity and depression in a variety of world regions in both healthy and HIV-infected individuals. We examined this association in 183 HIV-infected Hispanic adults from the greater Boston area. We measured depression with the Burnam depression screen and food insecurity with the Radimer/Cornell Questionnaire. Dietary intake was assessed with an adapted version of the Block Food Frequency Questionnaire. Logistic regression models were created with depression as the outcome variable and food insecurity as the main predictor. In bivariate analyses, food insecurity was significantly associated with depression [odds ratio (OR) 2.5; 95% confidence interval (CI) 1.1, 5.5; p = 0.03]. When we accounted for social support, food insecurity was no longer significant. We found no differences in the quality or quantity of dietary intake between the food insecure and food secure groups. Our findings highlight the importance of social support in the association between food insecurity and depression. Food insecurity may reflect social support more than actual dietary intake in this population.

Cognitive Remediation for Individuals with Psychosis in a Supported Education Setting: A Pilot Study

Directory of Open Access Journals (Sweden)

Sean A. Kidd

2012-01-01

Full Text Available Cognitive remediation (CR is a treatment approach that is being increasingly examined as a means through which the cognitive impacts of schizophrenia might be ameliorated. While CR has demonstrated good outcomes when paired with supported employment, little is known regarding how it might be integrated within supported education contexts. In this study CR was examined in a supported education context with 16 individuals with psychosis. The findings indicated that CR aligned well with the academic curriculum with very low attrition, was found useful by students, and showed similar pre-post differences on cognitive measures as those found in previous work.

Müller, Eve; Schuler, Adriana; Yates, Gregory B

2008-03-01

The study describes the perspectives of individuals with Asperger syndrome and other autism spectrum disabilities (ASDs) regarding social challenges and supports. Eighteen adults with ASDs were individually interviewed. They were asked to describe their experiences navigating their social worlds, and recommend effective social supports and strategies for improving social connectedness. Qualitative analyses of the interview transcripts revealed a number of common experiences including a profound sense of isolation, difficulty initiating social interactions, challenges relating to communication, longing for greater intimacy, desire to contribute to one's community, and effort to develop greater social/self-awareness. Commonly recommended social supports included external supports (e.g. activities based on shared interests, highly structured or scripted social activities, and small groups or dyads); communication supports (e.g. alternative modes of communication, explicit communication, and instruction in interpreting and using social cues); and self-initiated strategies for handling social anxiety (e.g. creative/improvisational outlets, physical activity, spiritual practice/organized religion, and time spent alone).

2013-09-01

Across several research studies comparing the individual placement and support (IPS) approach to traditional vocational services, the approach has achieved employment outcomes superior to comparison conditions. However, to understand the efficacy of IPS, it is equally important to consider what is more or less effective as viewed by the IPS participants. To investigate participants' experiences of IPS participation and their experiences of receiving support from an employment specialist (ES). Interviews were conducted with 17 persons with severe mental illness. The interviews were subjected to qualitative content analysis. The principles of informed consent and the voluntary nature of participation were included as ethical considerations. Participation in IPS was associated with hope, meaning and an individualized support provided by the ES. The skills of the ES facilitated the relationship with the participant and the contact with the labour market. However, to make a change happen, everybody involved in IPS had to contribute. These findings have endorsed the guiding principles of IPS and emphasized the ES's role and skills during IPS as well as the participant's motivation. © 2012 The Authors.

Proper selection of endogenous reference genes and their real-time PCR assays is quite important in genetically modified organisms (GMOs) detection. To find a suitable endogenous reference gene and its real-time PCR assay for common wheat (Triticum aestivum L.) DNA content or copy number quantification, four previously reported wheat endogenous reference genes and their real-time PCR assays were comprehensively evaluated for the target gene sequence variation and their real-time PCR performance among 37 common wheat lines. Three SNPs were observed in the PKABA1 and ALMT1 genes, and these SNPs significantly decreased the efficiency of real-time PCR amplification. GeNorm analysis of the real-time PCR performance of each gene among common wheat lines showed that the Waxy-D1 assay had the lowest M values with the best stability among all tested lines. All results indicated that the Waxy-D1 gene and its real-time PCR assay were most suitable to be used as an endogenous reference gene for common wheat DNA content quantification. The validated Waxy-D1 gene assay will be useful in establishing accurate and creditable qualitative and quantitative PCR analysis of GM wheat.

Can trust in politicians explain individuals' support for climate policy? The case of CO{sub 2} tax

Hammar, Henrik [Goeteborg Univ., Dept. of Economics, Goeteborg (Sweden); National Inst. of Economic Research (NIER), Stockholm (Sweden); Jagers, Sverker C. [Goeteborg Univ., Dept. of Polital Science, Goeteborg (Sweden)

This article provides an analysis of the support for public policies from a trust perspective. The empirical focus is on the use of a tax on carbon dioxide (CO{sub 2}), a policy tool aimed at coordinating national emissions targets in Sweden. Among economists and experts in the field of climate policy, a CO{sub 2} tax is viewed as a cost-effective policy. The policy problem is that public support for CO{sub 2} taxes is very low, leaving policy makers with high-cost options. Apart from traditional explanatory variables such as demographic factors, level of education, ideology and self-interest, what can explain this public opposition? Using individual level data, we analyse whether support for increases in the CO{sub 2} tax on gasoline can be explained by citizens' generalized trust in other individuals (who they do not necessarily know) or by their trust in politicians. We find that only the latter measure gains support in a regression analysis. Moreover, when splitting the sample into high-trusting and low-trusting individuals, we find that high-trusting individuals who have access to a car (compared with those without access) are statistically no more likely to resist increases in CO{sub 2} taxes than people without access to a car. Rather, it is individuals with access to a car and who do not trust their politicians who are likely to resist CO{sub 2} taxes. (Author)

Genetically modified organisms (GMOs), are gaining importance in agriculture as well as the production of food and feed. Along with the development of GMOs, health and food safety concerns have been raised. These concerns for these new GMOs make it necessary to set up strict system on food safety assessment of GMOs. The food safety assessment of GMOs, current development status of safety and precise transgenic technologies and GMOs detection have been discussed in this review. The recent patents about GMOs and their detection methods are also reviewed. This review can provide elementary introduction on how to assess and detect GMOs.

Support staff working with individuals with intellectual disability (ID) and challenging behaviour experience high levels of work-related stress. Preliminary theoretical and experimental research has highlighted the potential suitability of acceptance and mindfulness approaches for addressing support staff stress. This study examines the effectiveness of an acceptance and mindfulness-based stress management workshop on the levels of psychological distress and well-being of support staff working with individuals with ID and challenging behaviour. Support staff (n=120) were randomly assigned to a workshop intervention condition (n=66) or to a waiting list control condition (n=54). Measurements were completed at three time points (pre-, post and 6 week follow-up) for: psychological distress, well-being, perceived work stressors, thought suppression, and emotional avoidance/psychological inflexibility. The intervention led to significantly greater reductions in distress in the intervention group than in the control group. This was largely maintained at 6 week follow-up. This effect was more pronounced amongst a subsample that had shown higher levels of psychological distress at baseline. Thought suppression was found to reduce significantly in the intervention group between post intervention and follow-up, although no significant change was found in well-being or experiential avoidance/psychological inflexibility. Overall, results demonstrated support for the effectiveness of an acceptance and mindfulness-based intervention in reducing distress. Copyright © 2014 Elsevier Ltd. All rights reserved.

Modern Biotechnology—Potential Contribution and Challenges for Sustainable Food Production in Sub-Saharan Africa

Directory of Open Access Journals (Sweden)

E. Jane Morris

2011-06-01

Full Text Available Modern biotechnology, including the application of transgenic techniques to produce Genetically Modified Organisms (GMOs, can play a significant role in increasing agricultural production in a sustainable way, but its products need to be tailored for the developing world. In sub-Saharan Africa, the capacity to develop GMOs and ensure they meet stringent regulatory requirements is somewhat limited. Most African governments contribute little to science and technology either financially or through strong policies. This leaves the determination of research and development priorities in the hands of international funding agencies. Whereas funding from the United States is generally supportive of GM technology, the opposite is true of funding from European sources. African countries are thus pulled in two different directions. One alternative to this dilemma might be for countries in the sub-Saharan Africa region to develop stronger South-South collaborations, but these need to be supported with adequate funding. African governments as well as external funding agencies are urged to consider the important role that biotechnology, including GM technology, can play in contributing to sustainable development in Africa, and to provide adequate support to the development of capacity to research, develop and commercialize GMOs in the region.

Who is a survivor? Perceptions from individuals who experienced pediatric cancer and their primary support persons.

Molinaro, Monica L; Fletcher, Paula C

2018-04-01

The purpose of this research was to examine the lived experiences of individuals who had cancer as children, as well as lived experiences of their current primary support persons. Based on van Manen's "new" interpretive phenomenology, interviews were conducted with ten pediatric cancer survivors and nine of their support persons to gain a more holistic understanding of the pediatric cancer experiences of children and their families. Four themes emerged from the data; however, only the topic of the use of the term "survivor" and identification with the term will be discussed. All participants in the study described their personal definition of the term survivor and what it meant to be a survivor. Additionally, all individuals in the study discussed the concept of being a survivor and if they would consider themselves, or their loved ones, to be "survivors." The results of this study provide health care professionals, family members, and individuals fundraising or advocating for cancer causes with insights on how the term survivor may be interpreted. This study may provide insight to individuals who had cancer as children, in showing that their personal perspective shapes their identity; although "survivor" is common cancer vernacular, individuals can choose not to identify with their illness experiences.

The EU legislation on "GMOs" between nonsense and protectionism: An ongoing Schumpeterian chain of public choices.

Science.gov (United States)

Tagliabue, Giovanni

2017-01-02

The EU regulation of agricultural biotechnology is botched and convoluted: the pseudo-concept of "Genetically Modified Organisms" has no coherent semantic or scientific content. The reasons of the paradox by which the cultivation of "GMOs" is substantially banned in Europe, while enormous quantities of recombinant-DNA cereals and legumes are imported to be used as feedstuff, are explained. The Directive 2015/412, giving Member states the choice to refuse the cultivation of genetically engineered crops at a national or local level, paves the way for a mosaic-like, Harlequinesque form of protectionism: nothing resembling a well-regulated free market. In the meantime, importation of "GMO" feed goes on at full speed all over Europe. A proposal by the Commission to adjust the rules on importation according to those for cultivation has been rejected by the Parliament.This dynamics may be seen as an ongoing "Schumpeterian" chain of public choices: the calculus of consent drives politicians more than a science-based approach to law-making.  The EU should restart from scratch with the right concept, i.e. the careful examination of the pros and cons, the costs and benefits of each new agricultural product ("GMO" or otherwise), freely cultivated and/or imported, assessed case by case, at last acknowledging that the biotech processes used to create new varieties are of no practical or legal relevance. In doing so, the EU would pursue its stated "better regulation" approach, cancelling any sectoral and sectarian regulation.

This paper presents findings from a retrospective observational records review study that compares the outcomes associated with implementation of supported employment (SE) with and without prior Project SEARCH with ASD Supports (PS-ASD) on wages earned, time spent in intervention, and job retention. Results suggest that SE resulted in competitive employment for 45 adults with ASD. Twenty-five individuals received prior intervention through PS-ASD while the other 20 individuals received SE only. Individuals in this sample who received PS-ASD required fewer hours of intervention. Additionally, individuals in the PS-ASD group achieved a mean higher wage and had higher retention rates than their peers who received SE only. Further research with a larger sample is needed to confirm these findings.

Full Text Available This study evaluated the effect of implant-supported oral rehabilitation in the mandible on the electromyographic activity during mastication and swallowing in edentulous elderly individuals. Fifteen patients aged more than 60 years were evaluated, being 10 females and 5 males. All patients were edentulous, wore removable complete dentures on both dental arches, and had the mandibular dentures replaced by implant-supported prostheses. All patients were submitted to electromyographic evaluation of the masseter, superior orbicularis oris muscles, and the submental muscles, before surgery and 3, 6 and 18 months postoperatively, using foods of different textures. The results obtained at the different periods were analyzed statistically by Kruskal-Wallis non-parametric test. Statistical analysis showed that only the masseter muscle had a significant loss in electromyographic activity (p<0.001, with a tendency of similar response for the submental muscles. Moreover, there was an increase in the activity of the orbicularis oris muscle during rubber chewing after treatment, yet without statistically significant difference. Mandibular fixed implant-supported prostheses in elderly individuals revealed a decrease in electromyographic amplitude for the masseter muscles during swallowing, which may indicate adaptation to new conditions of stability provided by fixation of the complete denture in the mandibular arch.

Mandatory smoke-free policies in subsidized, multiunit housing (MUH) may decrease secondhand smoke exposure in households with the highest rates of exposure. Ideally, policies should be based on a strong understanding of factors affecting support for smoke-free policies in the target population to maximize effectiveness. A face-to-face survey was conducted from August to October 2011 using a stratified random sample of private subsidized housing units in Columbus, OH, without an existing smoke-free policy (n = 301, 64% response rate). Lease holders were asked to report individual, social, and environmental factors hypothesized to be related to support for smoke-free policies. Multiple logistic regression models were used to identify factors independently associated with policy support. Most tenants supported smoke-free policies in common areas (82.7%), half supported policies inside units (54.5%), and one third supported a ban outside the building (36.3%). Support for smoke-free policies in units and outdoors was more common among nonsmokers than smokers (71.5% vs. 35.7%, p social, but no environmental, factors were independently associated with policy support. Smokers who intended to quit within 6 months or less were more likely than other smokers to support in-unit policies (45.3% vs. 21.1%; p = .003). More than half of subsidized MUH tenants supported smoke-free policies inside their units. Strategies to address individual- and social-level barriers to behavior change should be implemented in parallel with smoke-free policies. Policies should be evaluated with objective measures to determine their effectiveness.

2009-01-01

Visual supports are widely used and generally regarded as an effective resource for intervention with individuals who function on the autism spectrum. More cross-contextual research into their efficacy is required. In this article, we selectively review the research literature around visual supports based on an original conceptual model that highlights their contribution in the interpersonal social and communicative milieu of classrooms, homes and other daily living contexts. Attention is drawn to a range of practical and research issues and challenges in the use of visual supports as well as evidence of their effectiveness in enhancing participation, learning and social membership in this population. Areas for further research relating to the introduction and use of visual supports with the autism spectrum disorder population are identified.

It can be challenging for support providers to facilitate effective social support interactions even when they have the best intentions. In the current article, we examine some reasons for this difficulty, with a focus on support recipients' self-esteem as a crucial variable. We predicted that recipients' receptiveness to support would be influenced by both support strategy and recipient self-esteem and that receptiveness in turn would impact providers' perceived caregiving efficacy and relationship quality. Study 1 (hypothetical scenarios), Study 2 (confederate interaction), and Study 3 (reports of recently received support) showed that individuals with low self-esteem (LSEs) are less receptive than are individuals with high self-esteem (HSEs) to support that positively reframes their experience but are equally receptive to support that validates their negative feelings. In Study 4, providers demonstrated some knowledge that positive reframing would be less helpful to LSEs than to HSEs but indicated equal intention to give such support. Study 5 showed that, in a real interaction, friends were indeed equally likely to offer positive reframing to both LSEs and HSEs but were less likely to offer validation to LSEs. LSEs were less accepting of such support, and in turn providers felt worse about the interaction, about themselves, and about their friendship more broadly. Study 6 confirmed that recipients' receptivity to support directly influenced providers' experience of a support interaction as well as their self- and relationship evaluations. The findings illustrate how well-meaning support attempts that do not match recipients' particular preferences may be detrimental to both members of the dyad.

A growing body of literature demonstrates that high-fidelity implementation of the individual placement and support (IPS) model of supported employment increases the chances of achieving desired outcomes. This study examined the relationship between IPS fidelity, as self-reported by program sites, and employment outcomes and determined whether this relationship was maintained over time. A total of 78 outpatient programs in New York State provided data on self-reported IPS fidelity and employment outcomes. Pearson correlations were used to determine the relationship between fidelity scores and competitive employment rates. A mixed-effects model examined the relationship between repeated fidelity and employment measures over time. A significant positive relationship was found between better self-reported IPS fidelity and greater employment. The relationship between IPS fidelity and employment was sustained over time (up to one year). Higher-fidelity implementation of the IPS model, as self-assessed by program sites, was associated with higher employment rates, which were sustained over time.

Depression is a mental illness affecting 121 million people. The Substance Abuse and Mental Health Services Administration recently launched a national, bilingual (English and Spanish) campaign to motivate young adults to support friends with mental illness. This article highlights and assesses the usefulness of two theoretically derived variables for increasing the social support received by all depressed individuals: (a) affect and (b) social support outcome expectations. In accord with the Substance Abuse and Mental Health Services Administration's bilingual campaign, the authors conducted two studies using intercepts at 2 swap meets in the U.S. Southwest. One study sample consisted of Spanish-dominant Hispanics, the other non-Hispanics. For both samples, results indicate that affect, social support outcome expectations, and their interaction accounted for more than 50% of the variance of social support intentions (67% in the Hispanic sample when familism was considered). Affect is commonplace in the helping behavior literature; results indicate social support outcome expectations deserve equal consideration. Moreover, an unexpected finding emerged: Perceiving a lack of willpower, need for attention, and lack of moral character to be the cause of depression resulted in increased sympathy among the Hispanic sample but increased anger among non-Hispanics.

This article explores how rebalancing efforts can support the needs of individuals aging with a lifelong disability. The National Balancing Indicator project examined the overall long-term supports and services system (LTSS) progress in five indicators within the Sustainability, Coordination and Transparency, and Prevention principles toward a balanced LTSS system for those aging with a lifelong disability. In assessing state efforts to create a balanced participant-directed LTSS system with the National Balancing Indicators, the findings suggest states are better equipping the system to handle a burgeoning population of individuals aging with a lifelong disability, but more progress is still needed. Overall, states need to continue to create a seamless system that allows individuals with lifelong disabilities to transition smoothly through the life course.

The purpose of this study was to examine the association between perceived family support, either positive or negative, and adherence to antiretroviral medication regimens among HIV-positive individuals in the Kathmandu Valley, Nepal. We measured past 3-month antiretroviral adherence among 233 HIV-positive individuals, in relation to perceived family support, both positive (in terms of emotional and instrumental support) and negative (in the form of negative interactions), using the 10-item Nepali Family Support and Difficulty Scale. Medium and high levels of perceived emotional support from family were associated with reduced risk of antiretroviral nonadherence, compared with low levels of perceived emotional support (adjusted odds ratio [AOR]  = 0.37, 95% confidence interval [CI] [0.16, 0.88], and AOR  = 0.23, 95% CI [0.08, 0.64], respectively). Conversely, higher levels of felt emotional distance (AOR  = 1.46, 95% CI [1.00, 2.14]) and experienced physical harm (AOR  = 2.04, 95% CI [1.07, 3.91]) were associated with increased risk of nonadherence. The results support the recommendation that service providers need to be aware of the significant role of family support in shaping antiretroviral adherence and to consider ways to strengthen positive family support while minimizing negative family interactions to increase adherence rates. © The Author(s) 2015.

An individual-oriented model on the emergence of support in fights, its reciprocation and exchange.

Directory of Open Access Journals (Sweden)

Charlotte K Hemelrijk

Full Text Available Complex social behaviour of primates has usually been attributed to the operation of complex cognition. Recently, models have shown that constraints imposed by the socio-spatial structuring of individuals in a group may result in an unexpectedly high number of patterns of complex social behaviour, resembling the dominance styles of egalitarian and despotic species of macaques and the differences between them. This includes affiliative patterns, such as reciprocation of grooming, grooming up the hierarchy, and reconciliation. In the present study, we show that the distribution of support in fights, which is the social behaviour that is potentially most sophisticated in terms of cognitive processes, may emerge in the same way. The model represents the spatial grouping of individuals and their social behaviour, such as their avoidance of risks during attacks, the self-reinforcing effects of winning and losing their fights, their tendency to join in fights of others that are close by (social facilitation, their tendency to groom when they are anxious, the reduction of their anxiety by grooming, and the increase of anxiety when involved in aggression. Further, we represent the difference in intensity of aggression apparent in egalitarian and despotic macaques. The model reproduces many aspects of support in fights, such as its different types, namely, conservative, bridging and revolutionary, patterns of choice of coalition partners attributed to triadic awareness, those of reciprocation of support and 'spiteful acts' and of exchange between support and grooming. This work is important because it suggests that behaviour that seems to result from sophisticated cognition may be a side-effect of spatial structure and dominance interactions and it shows that partial correlations fail to completely omit these effects of spatial structure. Further, the model is falsifiable, since it results in many patterns that can easily be tested in real primates by

Although an extensive body of literature highlights the important role of social support for individuals with psychiatric disabilities, definitions of support tend to be restricted-focusing on intimate relationships such as friend and family networks and ignoring the role of casual relationships existing naturally in the community. This mixed-methods study of 300 consumers of mental health services in the Southeastern US aims to better understand the impact of community supports, termed distal supports, on community integration and recovery from mental illness. Qualitative content analysis, tests of group mean differences, and hierarchical linear regression analyses revealed the following: (1) participants primarily reported receiving tangible support (e.g., free medication/discounted goods) from distal supports rather than emotional support (e.g., displays of warmth/affection) or informational support (e.g., provision of advice); (2) women and older participants reported more distal supports than men or younger participants; and (3) distal supports played a unique role in predicting community integration and recovery even after accounting for the influence of traditional support networks. Results highlight the importance of considering diverse types of social support in naturally occurring settings when designing treatment plans and interventions aimed at encouraging community participation and adaptive functioning for individuals with psychiatric disabilities.

Aims: Carbon-enhanced metal-poor (CEMP) stars represent a sizeable fraction of all known metal-poor stars in the Galaxy. Their formation and composition remains a significant topic of investigation within the stellar astrophysics community. Methods: We analysed a sample of low-resolution spectra of 30 dwarf stars, obtained using the visual and near UV FOcal Reducer and low dispersion Spectrograph for the Very Large Telescope (FORS/VLT) of the European Southern Observatory (ESO) and the Gemini Multi-Object Spectrographs (GMOS) at the GEMINI telescope, to derive their metallicity and carbon abundance. Results: We derived C and Ca from all spectra, and Fe and Ba from the majority of the stars. Conclusions: We have extended the population statistics of CEMP stars and have confirmed that in general, stars with a high C abundance belonging to the high C band show a high Ba-content (CEMP-s or -r/s), while stars with a normal C abundance or that are C-rich, but belong to the low C band, are normal in Ba (CEMP-no).

Individual behavioural support for smoking cessation is effective but little is known about the 'active ingredients'. As a first step to establishing this, it is essential to have a consistent terminology for specifying intervention content. This study aimed to develop for the first time a reliable taxonomy of behaviour change techniques (BCTs) used within individual behavioural support for smoking cessation. Two source documents describing recommended practice were identified and analysed by two coders into component BCTs. The resulting taxonomy of BCTs was applied to 43 treatment manuals obtained from the English Stop Smoking Services (SSSs). In the first 28 of these, pairs of coders applied the taxonomy independently and inter-coder reliability was assessed. The BCTs were also categorised by two coders according to their main function and inter-coder reliability for this was assessed. Forty-three BCTs were identified which could be classified into four functions: 1) directly addressing motivation e.g. providing rewards contingent on abstinence, 2) maximising self-regulatory capacity or skills e.g. facilitating barrier identification and problem solving, 3) promoting adjuvant activities e.g. advising on stop-smoking medication, and 4) supporting other BCTs e.g. building general rapport. Percentage agreement in identifying BCTs and of categorising BCTs into their functions ranged from 86% to 95% and discrepancies were readily resolved through discussion. It is possible to develop a reliable taxonomy of BCTs used in behavioural support for smoking cessation which can provide a starting point for investigating the association between intervention content and outcome and can form a basis for determining competences required to undertake the role of stop smoking specialist.

This report summarizes the work performed under contract DOE-FCO2-84ER45162. During the past ten years, our study of electron emission from laser-illuminated field emission tips has taken on a broader scope by addressing problems of direct interest to those concerned with the unique physical and chemical properties of nanometer-size clusters. The work performed has demonstrated that much needed data can be obtained on individual nanometer-size clusters supported on a wide-variety of different substrates. The work was performed in collaboration with R.P. Andres in the School of Chemical Engineering at Purdue University. The Multiple Expansion Cluster Source developed by Andres and his students was essential for producing the nanometer-size clusters studied. The following report features a discussion of these results. This report provides a motivation for studying the properties of nanometer-size clusters and summarizes the results obtained

The psychology of suicide terrorism involves more than simply the psychology of suicide. Individual differences in social dominance orientation (SDO) interact with the socio-structural, political context to produce support for group-based dominance among members of both dominant and subordinate groups. This may help explain why, in one specific context, some people commit and endorse terrorism, whereas others do not.

The burgeoning role of technology in society has provided opportunities for the development of new means of communication for individuals with Autism Spectrum Disorders (ASD). This paper offers an organizational framework for describing traditional and emerging augmentative and alternative communication (AAC) technology, and highlights how tools within this framework can support a visual approach to everyday communication and improve language instruction. The growing adoption of handheld media devices along with applications acquired via a consumer-oriented delivery model suggests a potential paradigm shift in AAC for people with ASD.

We identified the commercial releases of genetically modified organisms (GMOs) in Brazil, their characteristics, the types of genetic transformation used, and the companies responsible for the development of these GMOs, classifying them into two categories: private companies, subdivided into multinational and national, and public institutions. The data came from the data bank of the national registration of cultivars and the service of national protection of cultivars of the Ministry of Agriculture, Fishing and Supply (MAPA). This survey was carried out from 1998 to February 12, 2011. Until this date, 27 GMOs had been approved, including five for soybean, 15 for maize and seven for cotton cultivars. These GMOs have been used for the development of 766 cultivars, of which, 305 are soybean, 445 are maize, and 13 are cotton cultivars. The Monsato Company controls 73.2% of the transgenic cultivars certified by the MAPA; a partnership between Dow AgroSciences and DuPont accounts for 21.4%, and Syngenta controls 4.96%. Seed supply by these companies is almost a monopoly supported by law, giving no choice for producers and leading to the fast replacement of conventional cultivars by transgenic cultivars, which are expensive and exclude small producers from the market, since seeds cannot be kept for later use. This situation concentrates production in the hands of a few large national agribusiness entrepreneurs.

Hypothetical link between infertility and genetically modified food.

It is speculated that genetically modified food (GMF)/genetically modified organism (GMO) is responsible for infertility development. The risk linked with a wide use of GMFs/GMOs offers the basic elements for social criticism. However, to date, it has not been justified whether the bad effects are directly resulted from products of genetic modifications or trans-genesis process. Extensive experience with the risk assessment of whole foods has been applied recently on the safety and nutritional testing of GMFs/GMOs. Investigations have tested the safety of GMFs including sub-acute, chronic, reproductive, multi-generation and carcinogenicity studies. We extrapolated the potential risks associated with GMFs/GMOs on reproduction, and analyzed the multi-aspect linked between infertility and GMFs/GMOs. It could be conjectured that GMFs/GMOs could be potential hazard on reproduction, linking to the development of infertility through influencing the endocrine metabolism, endometriosis. However, little evidence shows the impaction on embryo or reproductive related tumor due to the limited literatures, and needs further research. The article presents some related patents on GMFs/GMOs, and some methods for tracking GMOs.

Research on the well-being of lesbian, gay, and bisexual (LGB) people has predominately focused on Western (-ized) societies where individualism, and not collectivism, is emphasized. In the present study, we utilized a mediator model via Structural Equation Modeling (SEM) to examine the relationships between self-compassion (i.e., self-kindness, common humanity, and mindfulness), perceived social support (i.e., family, friends, and significant others), and subjective well-being (i.e., life satisfaction, positive affect, and negative affect) in a sample of LGB-identified individuals living in Turkey, a traditionally collectivistic culture (Hofstede, 2001). A sample of 291 LGB individuals (67 lesbian, 128 gay, and 96 bisexual) completed an online survey including the Positive and Negative Affect Schedule, Satisfaction with Life Scale, Multidimensional Scale of Perceived Social Support Scale, and Self-kindness, Common Humanity, and Mindfulness subscales of the Self-Compassion Scale. The results of SEM for the hypothesized mediator model revealed that self-compassion mediated the relationships between perceived social support from family and significant others and subjective well-being, explaining the 77% of the variance in subjective well-being. Implications for the literature base on LGB well-being are discussed, with a focus on the cross-cultural applications. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

The DNA target sequence is the key element in designing detection methods for genetically modified organisms (GMOs). Unfortunately this information is frequently lacking, especially for unauthorized GMOs. In addition, patent sequences are generally poorly annotated, buried in complex and extensive documentation and hard to link to the corresponding GM event. Here, we present the JRC GMO-Amplicons, a database of amplicons collected by screening public nucleotide sequence databanks by in silico determination of PCR amplification with reference methods for GMO analysis. The European Union Reference Laboratory for Genetically Modified Food and Feed (EU-RL GMFF) provides these methods in the GMOMETHODS database to support enforcement of EU legislation and GM food/feed control. The JRC GMO-Amplicons database is composed of more than 240 000 amplicons, which can be easily accessed and screened through a web interface. To our knowledge, this is the first attempt at pooling and collecting publicly available sequences related to GMOs in food and feed. The JRC GMO-Amplicons supports control laboratories in the design and assessment of GMO methods, providing inter-alia in silico prediction of primers specificity and GM targets coverage. The new tool can assist the laboratories in the analysis of complex issues, such as the detection and identification of unauthorized GMOs. Notably, the JRC GMO-Amplicons database allows the retrieval and characterization of GMO-related sequences included in patents documentation. Finally, it can help annotating poorly described GM sequences and identifying new relevant GMO-related sequences in public databases. The JRC GMO-Amplicons is freely accessible through a web-based portal that is hosted on the EU-RL GMFF website. Database URL: http://gmo-crl.jrc.ec.europa.eu/jrcgmoamplicons/. © The Author(s) 2015.

To explore health care professionals' perspective of hospice at home service that has different components, individually tailored to meet the needs of patients. Over 50% of adults diagnosed with a terminal illness and the majority of people who have cancer, prefer to be cared for and to die in their own home. Despite this, most deaths occur in hospital. Increasing the options available for patients, including their place of care and death is central to current UK policy initiatives. Hospice at home services aim to support patients to remain at home, yet there are wide variations in the design of services and delivery. A hospice at home service was developed to provide various components (accompanied transfer home, crisis intervention and hospice aides) that could be tailored to meet the individual needs of patients. An evaluation study. Data were collected from 75 health care professionals. District nurses participated in one focus group (13) and 31 completed an electronic survey. Palliative care specialist nurses participated in a focus group (9). One hospital discharge co-ordinator and two general practitioners participated in semi-structured interviews and a further 19 general practitioners completed the electronic survey. Health care professionals reported the impact and value of each of the components of the service, as helping to support patients to remain at home, by individually tailoring care. They also positively reported that support for family carers appeared to enable them to continue coping, rapid access to the service was suggested to contribute to faster hospital discharges and the crisis intervention service was identified as helping patients remain in their own home, where they wanted to be. Health care professionals perceived that the additional individualised support provided by this service contributed to enabling patients to continue be cared for and to die at home in their place of choice. This service offers various components of a hospice

A wide range of research has accumulated detailing the positive associations of perceived organizational support (POS) with desirable workplace outcomes (e.g., high performance, high commitment, low deviance). In the process, there has been an implicit assumption that these relationships are linear, with ever-increasing POS resulting in ever-increasing positive outcomes. However, there are theoretical and practical reasons to question whether these relationships may be nonlinear rather than linear. Our results offer support for the notion that the relationships between POS and key individual outcomes rated by the supervisor may best be represented as nonlinear. We conclude by highlighting the implications for both theory and practice.

Increasing support for contraception as HIV prevention: stakeholder mapping to identify influential individuals and their perceptions.

Directory of Open Access Journals (Sweden)

Tricia Petruney

Full Text Available BACKGROUND: Voluntary contraceptive use by HIV-positive women currently prevents more HIV-positive births, at a lower cost, than anti-retroviral drug (ARV regimens. Despite this evidence, most prevention of mother-to-child transmission (PMTCT programs focus solely on providing ARV prophylaxis to pregnant women and rarely include the prevention of unintended pregnancies among HIV-positive women. METHODOLOGY/PRINCIPAL FINDINGS: To strengthen support for family planning as HIV prevention, we systematically identified key individuals in the field of international HIV/AIDS-those who could potentially influence the issue-and sought to determine their perceptions of barriers to and facilitators for implementing this PMTCT strategy. We used a criteria-based approach to determine which HIV/AIDS stakeholders have the most significant impact on HIV/AIDS research, programs, funding and policy and stratified purposive sampling to conduct interviews with a subset of these individuals. The interview findings pointed to obstacles to strengthening linkages between family planning and HIV/AIDS, including the need for: resources to integrate family planning and HIV services, infrastructure or capacity to provide integrated services at the facility level, national leadership and coordination, and targeted advocacy to key decision-makers. CONCLUSIONS/SIGNIFICANCE: The individuals we identified as having regional or international influence in the field of HIV/AIDS have the ability to leverage an increasingly conducive funding environment and a growing evidence base to address the policy, programmatic and operational challenges to integrating family planning with HIV/AIDS. Fostering greater support for implementing contraception for HIV prevention will require the dedication, collaboration and coordination of many such actors. Our findings can inform a targeted advocacy campaign.

Hughes, Jan N; Im, Myung Hee; Wehrly, Sarah E

2014-06-01

This longitudinal study examined the prospective relations between 713 elementary students' individual peer teacher support reputation (PTSR) and a measure of the classroom-wide dispersion of peer nominations of teacher support (Centralization of Teacher Support) on students' peer relatedness (i.e., peer acceptance and peer academic reputation) and academic motivation (i.e., academic self-efficacy and teacher-rated behavioral engagement). PTSR was measured as the proportion of classmates who nominated a given student on a descriptor of teacher-student support. Centralization of Teacher Support was assessed using social network analysis to identify the degree to which peer nominations of teacher support in a classroom centered on a few students. PTSR predicted changes in all student outcomes, above academic achievement and relevant covariates. Centralization of Teacher Support predicted changes in students' peer academic reputation, net the effect of PTSR and covariates. Students' academic achievement moderated effects of PTSR and Centralization of Teacher Support on some outcomes. Findings highlight the importance of peers' perceptions of teacher support and of the structure of those perceptions for children's social and academic outcomes. Implications for practice are discussed. Copyright © 2014 Society for the Study of School Psychology. Published by Elsevier Ltd. All rights reserved.

Who Should We Target? The Impact of Individual and Family Characteristics on the Expressed Need for Community-Based Treatment Support in HIV Patients in South Africa.

Directory of Open Access Journals (Sweden)

Edwin Wouters

Full Text Available Reviews of impact evaluations of community-based health workers and peer support groups highlight the considerable variability in the effectiveness of such support in improving antiretroviral treatment (ART outcomes. Evidence indicates that community-based support interventions targeting patients known to be at risk will probably display better results than generic interventions aimed at the entire population of people living with HIV. It is however difficult to identify these at-risk populations, rendering knowledge on the characteristics of patients groups who are in need of community-based support a clear research priority. The current study aims to address the knowledge gap by exploring the predictors of the willingness to (1 receive the support from a community-based health worker or (2 to participate in a support group in public sector ART programme of the Free State Province of South Africa. Based on the Individual-Family-Community framework for HIV research, the study employs a comprehensive approach by not only testing classical individual-level but also family-level predictors of the willingness to receive community-based support. In addition to individual-level predictors-such as age, health status and coping styles-our analysis demonstrated the importance of family characteristics. The results indicated that discrepancies in the family's changeability level were an important predictor of the demand for community-based support services. Conversely, the findings indicated that patients living in a family more flexible than deemed ideal are more likely to require the support of a community health worker. The current study expands theory by indicating the need to acknowledge all social ecological levels in the study of chronic HIV care. The detection of both individual level and family level determinants of the expressed need for community-based support can inform health policy to devise strategies to target scarce resources to those

Full Text Available Abstract Background Different strategies have been used to improve the initiation and duration of breastfeeding. Peer counsellors are reported to improve exclusive breastfeeding levels, but few studies have assessed the satisfaction of women with the support given, especially in Africa. In this paper we describe women's experiences of peer counselling for exclusive breastfeeding in an East African setting. Methods In the Ugandan site of PROMISE-EBF, a multi-centre community randomised trial to evaluate the effect of peer counselling for exclusive breastfeeding on infant health, 370 women in the intervention arm participated in a study exit interview. Individual peer counselling was offered to women in 12 of the 24 study clusters, scheduled as five visits: before childbirth and during weeks 1, 4, 7 and 10 after childbirth. During the visits, the women were given information and skills to help them breastfeed exclusively. After the 10-week visit, they were interviewed about their feelings and experiences related to the peer counselling. Results Overall, more than 95% of the women expressed satisfaction with the various aspects of peer counselling offered. Those who had received five or more visits were more likely to give positive responses about their experience with peer counselling than those who had received fewer visits. They explained their satisfaction with time spent with the peer counsellor in terms of how much she discussed with them. Most women felt their knowledge needs about breastfeeding were covered by the peer counsellors, while others expressed a desire to learn about complementary feeding and family planning. Attributes of the peer counsellors included their friendliness, being women and giving support in a familiar and relaxed way. Women were positive about the acquisition of knowledge and the benefit to their babies from the peer counselling. They preferred a peer counsellor to a health worker for support of exclusive

The success of treatment for substance use issues varies with personal and social factors, including the composition and structure of the individual's personal support network. This paper describes the personal support networks and social capital of a sample of Italian adults after long-term residential therapeutic treatment for substance use issues, and analyses network correlates of post-treatment substance use (relapse). Using a social network analysis approach, data were obtained from structured interviews (90-120 min long) with 80 former clients of a large non-governmental therapeutic treatment agency in Italy providing voluntary residential treatments and rehabilitation services for substance use issues. Participants had concluded the program at least six months prior. Data were collected on socio-demographic variables, addiction history, current drug use status (drug-free or relapsed), and the composition and structure of personal support networks. Factors related to risk of relapse were assessed using bivariate and multivariate logistic regression models. A main goal of this study was to identify differences between the support network profiles of drug free and relapsed participants. Drug free participants had larger, less dense, more heterogeneous and reciprocal support networks, and more brokerage social capital than relapsed participants. Additionally, a lower risk of relapse was associated with higher socio-economic status, being married/cohabiting, and having network members with higher socio-economic status, who have greater occupational heterogeneity, and reciprocate support. Post-treatment relapse was found to be negatively associated with the socioeconomic status and occupational heterogeneity of ego's support network, reciprocity in the ties between ego and network members, and a support network in which the members are relatively loosely connected with one another (i.e., ego possesses "brokerage social capital"). These findings suggest the

As the worldwide commercialization of genetically modified organisms (GMOs) increases and consumers concern the safety of GMOs, many countries and regions are issuing labeling regulations on GMOs and their products. Analytical methods and their standardization for GM ingredients in foods and feed are essential for the implementation of labeling regulations. To date, the GMO testing methods are mainly based on the inserted DNA sequences and newly produced proteins in GMOs. This paper presents an overview of GMO testing methods as well as their standardization. © 2011 Institute of Botany, Chinese Academy of Sciences.

Examining the psychological sense of community for individuals with serious mental illness residing in supported housing environments.

The psychological sense of community is an important aspect of community life; yet, it remains largely unexamined among individuals with serious mental illness (SMI). Sense of community represents the strength of bonding among community members; and this social phenomenon likely impacts the process by which individuals with SMI integrate into community life. The current study examined sense of community (SOC) for individuals with SMI by assessing the relationships between neighborhood experiences, unique factors related to SMI (e.g., mental illness diagnosis), and sense of community in the neighborhood. Participants were 402 residents of supported housing programs who used mental health services in South Carolina. Hierarchical linear regression was utilized to determine which components of community life helped to explain variability in sense of community. In total, 214 participants reported that it is very important for them to feel a sense of community in their neighborhoods. Neighbor relations, neighborhood safety, neighborhood satisfaction, neighborhood tolerance for mental illness, and housing site type emerged as significant explanatory variables of sense of community. These findings have implications for interventions aimed at enhancing SOC and community integration for individuals with SMI.

To investigate the effects of gait training with body weight support (BWS) on a treadmill versus overground in individuals with chronic stroke. Randomized controlled trial. University research laboratory. Individuals (N=28) with chronic stroke (>6mo from the stroke event). Participants were randomly assigned to receive gait training with BWS on a treadmill (n=14) or overground (n=14) 3 times a week for 6 weeks. Gait speed measured using the 10-meter walk test, endurance measured using the 6-minute walk test, functional independence measured using the motor domain of the FIM, lower limb recovery measured using the lower extremity domain of the Fugl-Meyer assessment, step length, step length symmetry ratio, and single-limb support duration. Measurements were obtained at baseline, immediately after the training session, and 6 weeks after the training session. At 1 week after the last training session, both groups improved in all outcome measures except paretic step length and step length symmetry ratio, which were improved only in the overground group (P=.01 and P=.01, respectively). At 6 weeks after the last training session, all improvements remained and the treadmill group also improved paretic step length (P.05). Individuals with chronic stroke equally improve gait speed and other gait parameters after 18 sessions of BWS gait training on either a treadmill or overground. Only the overground group improved step length symmetry ratio, suggesting a role of integrating overground walking into BWS interventions poststroke.

Introduction of social commerce websites has bought shift in consumers׳ buying decision, i.e. from individual to social shopping. This study aims to identify factors that influence an individual׳s decision to use social commerce websites in an Indian Context. A conceptual model was developed based on extensive literature review. Wherein total six factors that influence an individual׳s intention to use social commerce were identified and were divided into three broad categories: social factors (informational support and community commitment, trust (towards members and community and website quality (ease of use and service quality. Research model was empirically examined using structural equation modeling. The findings of this study demonstrated positive relationship between all six factors and an individual׳s intention to use social commerce website. Additionally, study identified informational support as the most significant factor that influences an individual׳s intention to use social commerce website followed by trust towards members, service equality, trust towards community, ease of navigation, and community commitment.

We used a Support Vector Machine (SVM) classifier to assess hemispheric pattern of language dominance of 47 individuals categorized as non-typical for language from their hemispheric functional laterality index (HFLI) measured on a sentence minus word-list production fMRI-BOLD contrast map. The SVM classifier was trained at discriminating between Dominant and Non-Dominant hemispheric language production activation pattern on a group of 250 participants previously identified as Typicals (HFLI strongly leftward). Then, SVM was applied to each hemispheric language activation pattern of 47 non-typical individuals. The results showed that at least one hemisphere (left or right) was found to be Dominant in every, except 3 individuals, indicating that the "dominant" type of functional organization is the most frequent in non-typicals. Specifically, left hemisphere dominance was predicted in all non-typical right-handers (RH) and in 57.4% of non-typical left-handers (LH). When both hemisphere classifications were jointly considered, four types of brain patterns were observed. The most often predicted pattern (51%) was left-dominant (Dominant left-hemisphere and Non-Dominant right-hemisphere), followed by right-dominant (23%, Dominant right-hemisphere and Non-Dominant left-hemisphere) and co-dominant (19%, 2 Dominant hemispheres) patterns. Co-non-dominant was rare (6%, 2 Non-Dominant hemispheres), but was normal variants of hemispheric specialization. In RH, only left-dominant (72%) and co-dominant patterns were detected, while for LH, all types were found, although with different occurrences. Among the 10 LH with a strong rightward HFLI, 8 had a right-dominant brain pattern. Whole-brain analysis of the right-dominant pattern group confirmed that it exhibited a functional organization strictly mirroring that of left-dominant pattern group.

Body weight support (BWS) systems on treadmill have been proposed as a strategy for gait training of subjects with stroke. Considering that ground level is the most common locomotion surface and that there is little information about individuals with stroke walking with BWS on ground level, it is important to investigate the use of BWS on ground level in these individuals as a possible alternative strategy for gait training. Thirteen individuals with chronic stroke (four women and nine men; mean age 54.46 years) were videotaped walking on ground level in three experimental conditions: with no harness, with harness bearing full body weight, and with harness bearing 30% of full body weight. Measurements were recorded for mean walking speed, cadence, stride length, stride speed, durations of initial and terminal double stance, single limb support, swing period, and range of motion of ankle, knee, and hip joints; and foot, shank, thigh, and trunk segments. The use of BWS system leads to changes in stride length and speed, but not in stance and swing period duration. Only the hip joint was influenced by the BWS system in the 30% BWS condition. Shank and thigh segments presented less range of motion in the 30% BWS condition than in the other conditions, and the trunk was held straighter in the 30% BWS condition than in the other conditions. Individuals with stroke using BWS system on ground level walked slower and with shorter stride length than with no harness. BWS also led to reduction of hip, shank, and thigh range of motion. However, this system did not change walking temporal organization and body side asymmetry of individuals with stroke. On the other hand, the BWS system enabled individuals with chronic stroke to walk safely and without physical assistance. In interventions, the physical therapist can watch and correct gait pattern in patients' performance without the need to provide physical assistance.

Genetically modified organisms (GMOs) have been available for commercial purchase since the 1990s, allowing producers to increase crop yields through bioengineering that creates herbicide-resistant and insect-resistant varieties. However, consumer knowledge about GMOs has not increased at the same rate as the adoption of GMO crops. Consumers worldwide are displaying limited understanding, misconceptions, and even unfamiliarity with GMO food products. Many consumers report that they receive information about GMO food products from the media, Internet, and other news sources. These sources may be less reliable than scientific experts whom consumers trust more to present the facts. Although many in the United States support mandatory GMO labeling (similar to current European standards), consumer awareness of current GMO labeling is low. A distinction must also be made between GMO familiarity and scientific understanding, because those who are more familiar with it tend to be more resistant to bioengineering, whereas those with higher scientific knowledge scores tend to have less negative attitudes toward GMOs. This brings to question the relation between scientific literacy, sources of information, and overall consumer knowledge and perception of GMO foods. © 2015 American Society for Nutrition.

Not all people with severe mental illness who attend Individual Placement and Support (IPS) gain and keep their jobs or work full time. Research has indicated a relationship between social disabilities and work performance in this group, and that support provided is often directed towards the social work environment. However, relationships between social skills performed in an authentic work setting and vocational outcomes have not been explored. To explore relationships between social communication and interaction skills and vocational outcomes among IPS service users in a Swedish context. Twenty-nine participants were appraised with the Assessment of Communication and Interaction Skills (ACIS-S) instrument, and their vocational data were registered. Correlations were estimated using Spearman's rho test with Bonferroni corrections at item level. Better communication and interaction skills were significantly correlated with increased working hours (rs = 0.64) and higher income (rs = 0.45). Increased working hours were related to assuming postures, asking questions, sharing information, and sustaining conversation in an appropriate manner. The results indicate that occupational therapists need to focus on social skills and accommodation of the social work environment in order to promote sustainable working careers among people with severe mental illness.

Objective Although Australia's service and policy context differs from that of the US, studies have highlighted potential for individual placement and support (IPS) to support competitive employment outcomes for people with severe and persistent mental illness. The aim of the present study was to explore why the model is not yet widely available. Methods A document analysis was conducted to discern reasons for challenges in implementation of IPS practice principles within the Australian service context. Results The document analysis illustrated that although policy acknowledges the importance of increasing employment rates for people with severe and persistent mental illness, consistent measures, change indicators, direction and time frames are lacking in policy and strategy documentation. Further, IPS principles are not consistently evident in guiding operational documentation that government-funded Disability Employment Services (DES) programs are mandated to adhere to. Conclusions For IPS to be readily implemented, it is necessary for government to offer support to agencies to partner and formal endorsement of the model as a preferred approach in tendering processes. Obligations and processes must be reviewed to ensure that model fidelity is achievable within the Australian Commonwealth policy and service context for programs to achieve competitive employment rates comparable to the most successful international programs. What is known about the topic? The IPS model has been established as the most efficacious approach to support people with severe and persistent mental ill health to gain and sustain employment internationally, yet little is known as to why this model has had very limited uptake in the Australian adult mental health service and policy context. What does this paper add? This paper provides an investigation into the achievability of IPS within DES philosophical and contractual arrangements. What are the implications for practitioners?

Full Text Available The Global Mercury Observation System (GMOS Project includes a specific Work Package aimed at developing tools (i.e. databases, catalogs, services to collect GMOS datasets, harvest mercury databases, and offer services like search, view, and download spatial datasets from the GMOS portal (www.gmos.eu. The system will be developed under the framework of the Infrastructure for Spatial Information in the European Community (INSPIRE Directive and the Directive 2003/4/EC on public access to environmental information, which both aim to make relevant, harmonized, high-quality geographic information available to support the formulation, implementation, monitoring, and evaluation of policies and activities that have a direct or indirect impact on the environment. Three databases have been proposed (on emissions, field data and model results, and each will be equipped with state-of-the-art, open-source software to allow for the highest performance possible. Web-based user-interfaces and prototype applications will be developed to demonstrate the potential of blending different datasets from different servers for environmental assessment studies. Several services (i.e. catalog browsers, WMS and WCS services, web GIS services will be developed to facilitate data integration, data re-use, and data exchange within and beyond the GMOS project. Different types of measurement and model datasets provided by project partners and other sources will be integrated into PostgreSQL-PostGIS, harmonized by creating INSPIRE-compliant metadata and made available to a larger community of stakeholders, policy makers, scientists, and NGOs (as well as to other public and private institutions, as dictated by the Directive 2003/4/EC.

Youth living with HIV (YLH) experience multiple disease-related stresses along with the same structural and developmental challenges faced by their uninfected peers; alcohol use among YLH represents a risk behavior by virtue of potential effects on youth health and increased likelihood of engaging in unprotected sex while drinking alcohol. Research aimed at better understanding the interplay of individual- and neighborhood-level influences on alcohol use for YLH is needed to inform interventions. This study examined whether socioeconomic disadvantage (SED) and social support influence, independently and through interaction, alcohol use in YLH. Data from the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) consisted of YLH across 538 neighborhoods in the United States who acquired HIV behaviorally. Neighborhood-specific data were compiled from the 2010 U.S. Census Bureau and matched with individual-level data from the ATN (N = 1,357) to examine effects that contribute to variation in frequency of alcohol use. Other drug use, being male, being non-Black, and older age were associated with greater alcohol use. Higher social support was negatively associated with alcohol use frequency. A cross-level interaction indicated that the association found between decreasing social support and increasing alcohol use frequency was weakened in areas with lower SED. Implications are discussed. © Society for Community Research and Action 2018.

See what you eat--broad GMO screening with microarrays.

von Götz, Franz

2010-03-01

Despite the controversy of whether genetically modified organisms (GMOs) are beneficial or harmful for humans, animals, and/or ecosystems, the number of cultivated GMOs is increasing every year. Many countries and federations have implemented safety and surveillance systems for GMOs. Potent testing technologies need to be developed and implemented to monitor the increasing number of GMOs. First, these GMO tests need to be comprehensive, i.e., should detect all, or at least the most important, GMOs on the market. This type of GMO screening requires a high degree of parallel tests or multiplexing. To date, DNA microarrays have the highest number of multiplexing capabilities when nucleic acids are analyzed. This trend article focuses on the evolution of DNA microarrays for GMO testing. Over the last 7 years, combinations of multiplex PCR detection and microarray detection have been developed to qualitatively assess the presence of GMOs. One example is the commercially available DualChip GMO (Eppendorf, Germany; http://www.eppendorf-biochip.com), which is the only GMO screening system successfully validated in a multicenter study. With use of innovative amplification techniques, promising steps have recently been taken to make GMO detection with microarrays quantitative.

This paper describes the background, principles, concepts and methods of framing the technical regulation for edible safety requirement and assessment of agricultural genetically modified organisms (agri-GMOs) for Shenzhen Special Economic Zone in the People's Republic of China. It provides a set of systematic criteria for edible safety requirements and the assessment process for agri-GMOs. First, focusing on the degree of risk and impact of different agri-GMOs, we developed hazard grades for toxicity, allergenicity, anti-nutrition effects, and unintended effects and standards for the impact type of genetic manipulation. Second, for assessing edible safety, we developed indexes and standards for different hazard grades of recipient organisms, for the influence of types of genetic manipulation and hazard grades of agri-GMOs. To evaluate the applicability of these criteria and their congruency with other safety assessment systems for GMOs applied by related organizations all over the world, we selected some agri-GMOs (soybean, maize, potato, capsicum and yeast) as cases to put through our new assessment system, and compared our results with the previous assessments. It turned out that the result of each of the cases was congruent with the original assessment.

We present two-dimensional stellar and gaseous kinematics of the inner 0.7 × 1.2 kpc2 of the Seyfert 1.5 galaxy ESO 362-G18, derived from optical (4092-7338 Å) spectra obtained with the GMOS integral field spectrograph on the Gemini South telescope at a spatial resolution of ≈170 pc and spectral resolution of 36 km s-1. ESO 362-G18 is a strongly perturbed galaxy of morphological type Sa or S0/a, with a minor merger approaching along the NE direction. Previous studies have shown that the [O III] emission shows a fan-shaped extension of ≈10'' to the SE. We detect the [O III] doublet, [N II] and Hα emission lines throughout our field of view. The stellar kinematics is dominated by circular motions in the galaxy plane, with a kinematic position angle of ≈137° and is centred approximately on the continuum peak. The gas kinematics is also dominated by rotation, with kinematic position angles ranging from 122° to 139°, projected velocity amplitudes of the order of 100 km s-1, and a mean velocity dispersion of 100 km s-1. A double-Gaussian fit to the [O III]λ5007 and Hα lines, which have the highest signal to noise ratios of the emission lines, reveal two kinematic components: (1) a component at lower radial velocities which we interpret as gas rotating in the galactic disk; and (2) a component with line of sight velocities 100-250 km s-1 higher than the systemic velocity, interpreted as originating in the outflowing gas within the AGN ionization cone. We estimate a mass outflow rate of 7.4 × 10-2 M⊙ yr-1 in the SE ionization cone (this rate doubles if we assume a biconical configuration), and a mass accretion rate on the supermassive black hole (SMBH) of 2.2 × 10-2 M⊙ yr-1. The total ionized gas mass within 84 pc of the nucleus is 3.3 × 105 M⊙; infall velocities of 34 km s-1 in this gas would be required to feed both the outflow and SMBH accretion.

To assess the effectiveness of an individual placement and support (IPS) strategy in people with severe mental disorders in Tenerife Island (Spain). Patients of Community Mental Health Services with severe mental disorders were randomly assigned to two groups. One of them received IPS (n=124), and the control group (n=75) was advised in the usual job search. Patients were followed up for an average of 3.4 years and an analysis was made of how many patients worked at least one day, working hours, wages, the number of contracts and the number of hospital admissions. Non-parametric methods were used to compare the results (Mann-Whitney U test). The percentage of patients who worked at least one day was 99% in the IPS group compared with 75% in the control group; they worked on average 30.1 weeks per year vs 7.4; the monthly salary was € 777.9 vs € 599.9; the number of contracts per person was 3.89 vs 4.85, and hospital admissions were 0.19 vs 2.1. The IPS strategy is effective for the labour integration of people with severe mental illness getting them to work longer, have higher wages and fewer hospital admissions. Copyright © 2017 SESPAS.

We present Gemini Multi-Object Spectrograph (GMOS) Integral field Unit (IFU), Very Large Array (VLA), and Hubble Space Telescope (HST) observations of the OH megamaser (OHM) galaxy IRAS F23199+0123. Our observations show that this system is an interacting pair, with two OHM sources associated with the eastern (IRAS 23199E) member. The two members of the pair present somewhat extended radio emission at 3 and 20 cm, with flux peaks at each nucleus. The GMOS-IFU observations cover the inner ˜6 kpc of IRAS 23199E at a spatial resolution of 2.3 kpc. The GMOS-IFU flux distributions in Hα and [N II] λ6583 are similar to that of an HST [N II]+Hα narrow-band image, being more extended along the north-east-south-west direction, as also observed in the continuum HST F814W image. The GMOS-IFU Hα flux map of IRAS 23199E shows three extranuclear knots attributed to star-forming complexes. We have discovered a Seyfert 1 nucleus in this galaxy, as its nuclear spectrum shows an unresolved broad (full width at half-maximum ≈2170 km s-1) double-peaked Hα component, from which we derive a black hole mass of M_{BH} = 3.8^{+0.3}_{-0.2}× 106 M⊙. The gas kinematics shows low velocity dispersions (σ) and low [N II]/Hα ratios for the star-forming complexes and higher σ and [N II]/Hα surrounding the radio emission region, supporting interaction between the radio plasma and ambient gas. The two OH masers detected in IRAS F23199E are observed in the vicinity of these enhanced σ regions, supporting their association with the active nucleus and its interaction with the surrounding gas. The gas velocity field can be partially reproduced by rotation in a disc, with residuals along the north-south direction being tentatively attributed to emission from the front walls of a bipolar outflow.

How individual traces and interactive timelines could support outage execution - Toward an outage historian concept

International Nuclear Information System (INIS)

Parfouru, S.; De-Beler, N.

2012-01-01

In the context of a project that is designing innovative ICT-based solutions for the organizational concept of outage management, we focus on the informational process of the OCR (Outage Control Room) underlying the execution of the outages. Informational process are based on structured and unstructured documents that have a key role in the collaborative processes and management of the outage. We especially track the structured and unstructured documents, electronically or not, from creation to sharing. Our analysis allows us to consider that the individual traces produced by an individual participant with a specific role could be multi-purpose and support sharing between participants without creating duplication of work. The ultimate goal is to be able to generate an outage historian, that is not just focused on highly structured information, which could be useful to improve the continuity of information between participants. We study the implementation of this approach through web technologies and social media tools to address this issue. We also investigate the issue of data access through interactive visualization timelines coupled with other modality's to assist users in the navigation and exploration of the proposed historian.

2005-01-01

With the development of biotechnology, more and more genetically modified organisms (GMOs) have entered commercial market. Because of the safety concerns, detection and characterization of GMOs have attracted much attention recently. Electrochemiluminescence (ECL) method is a chemiluminescent (CL) reaction of species generated electrochemically on an electrode surface. It is a highly efficient and accurate detection method. In this paper, ECL polymerase chain reaction (PCR) combined with two types of nucleic acid probes hybridization was applied to detect GMOs for the first time. Whether the organisms contain GM components was discriminated by detecting the cauliflower mosaic virus 35S (CaMV35S) promoter and nopaline synthase (NOS) terminator. The experiment results show that the detection limit is 100 fmol of PCR products. The promoter and the terminator can be clearly detected in GMOs. The method may provide a new means for the detection of GMOs due to its simplicity and high efficiency

In this work, ultrasmall core-shell Fe 3 O 4 @Au magnetic nanoparticles (MNPs) were used as the platform for the immobilization of event-specific Roundup Ready (RR) soybean and taxon-specific DNA sequences. Firstly, monodisperse Fe 3 O 4 MNPs were synthesized by thermal decomposition and subsequently coated with a gold shell through reduction of Au(III) precursor on the surface of the MNPs in the presence of an organic capping agent. This nanosupport exhibited high colloidal stability, average particle size of 10.2 ± 1.3 nm, and spherical shape. The covalent immobilization of ssDNA probe onto the Au shell of the Fe 3 O 4 @Au MNPs was achieved through a self-assembled monolayer (SAM) created from mixtures of alkane thiols (6-mercapto-1-hexanol and mercaptohexanoic acid). The influence of the thiols ratio on the electrochemical performance of the resulting electrochemical genoassays was studied, and remarkably, the best analytical performance was achieved for a pure mercaptohexanoic acid SAM. Two quantification assays were designed; one targeting an RR sequence and a second targeting a reference soybean gene, both with a sandwich format for hybridization, signaling probes labelled with fluorescein isothiocyanate (FITC), enzymatic amplification and chronoamperometric detection at screen-printed carbon electrodes (SPCE). The magnetogenoassays exhibited linear ranges from 0.1 to 10.0 nM and from 0.1 to 5.0 nM with similar detection limits of 0.02 nM and 0.05 nM for the event-specific (RR) and the taxon-specific (lectin) targets, respectively. The usefulness of the approach was demonstrated by its application to detect genetically modified organisms (GMOs) in feed and food. Copyright © 2018 Elsevier B.V. All rights reserved.

Purpose Breastfeeding has been linked to a host of positive health effects for women and children. However, disparities in breastfeeding initiation and duration prevent many low-income and African-American women from realizing these benefits. Existing breastfeeding promotion efforts often do not reach women who need support the most. In response, the Westside Healthy Start program (WHS), located in Chicago, Illinois, developed an ongoing multilevel approach to breastfeeding promotion. Description Key elements of our WHS breastfeeding model include individual education and counseling from pregnancy to 6 months postpartum and partnership with a local safety-net hospital to implement the Baby-Friendly Hospital Initiative and provide lactation support to delivering patients. Assessment In the year our model was implemented, 44.6% (49/110) of prenatal WHS participants reported that they planned to breastfeed, and 67.0% (183/273) of delivered participants initiated. Among participants reaching 6 months postpartum, 10.5% (9/86) were breastfeeding. WHS also had 2667 encounters with women delivering at our partner hospital during breastfeeding rounds, with 65.1% of contacts initiating. Community data was not available to assess the efficacy of our model at the local level. However, WHS participants fared better than all delivering patients at our partner hospital, where 65.0% initiated in 2015. Conclusion Healthy Start programs are a promising vehicle to improve breastfeeding initiation at the individual and community level. Additional evaluation is necessary to understand barriers to duration and services needed for this population.

Stroke patients conventionally undergo a substantial part of their rehabilitation in hospital. Services have been developed that offer patients early discharge from hospital with rehabilitation at home (early supported discharge [ESD]). We have assessed the effects and costs of such services. We did a meta-analysis of data from individual patients who took part in randomised trials that recruited patients with stroke in hospital to receive either conventional care or any ESD service intervention that provided rehabilitation and support in a community setting with the aim of shortening the duration of hospital care. The primary outcome was death or dependency at the end of scheduled follow-up. Outcome data were available for 11 trials (1597 patients). ESD services were mostly provided by specialist multidisciplinary teams to a selected group (median 41%) of stroke patients admitted to hospital. There was a reduced risk of death or dependency equivalent to six (95% CI one to ten) fewer adverse outcomes for every 100 patients receiving an ESD service (p=0.02). The hospital stay was 8 days shorter for patients assigned ESD services than for those assigned conventional care (pstroke patients with mild to moderate disability. Appropriately resourced ESD services provided for a selected group of stroke patients can reduce long-term dependency and admission to institutional care as well as shortening hospital stays.

Full Text Available The identification of individuals at high risk of developing psychosis is entirely based on clinical assessment, associated with limited predictive potential. There is therefore increasing interest in the development of biological markers that could be used in clinical practice for this purpose. We studied 25 individuals with an At Risk Mental State for psychosis and 25 healthy controls using structural MRI, and functional MRI in conjunction with a verbal memory task. Data were analysed using a standard univariate analysis, and with Support Vector Machine (SVM, a multivariate pattern recognition technique that enables statistical inferences to be made at the level of the individual, yielding results with high translational potential. The application of SVM to structural MRI data permitted the identification of individuals at high risk of psychosis with a sensitivity of 68% and a specificity of 76%, resulting in an accuracy of 72% (p<0.001. Univariate volumetric between-group differences did not reach statistical significance. In contrast, the univariate fMRI analysis identified between-group differences (p<0.05 corrected while the application of SVM to the same data did not. Since SVM is well suited at identifying the pattern of abnormality that distinguishes two groups, whereas univariate methods are more likely to identify regions that individually are most different between two groups, our results suggest the presence of focal functional abnormalities in the context of a diffuse pattern of structural abnormalities in individuals at high clinical risk of psychosis.

Full Text Available Abstract Background The objective of the present study was to evaluate the short- and long-term intervention and mediation effects of a 3-month individualized need-supportive physical activity (PA counseling intervention on employees’ PA and sedentary behavior. Methods Insufficiently active employees (n = 300; mean age 42 ± 9 years; 78% female were recruited from a large pharmaceutical company in Flanders, Belgium. A quasi-experimental design was used in which the intervention group (N = 246 was recruited separately from the reference group (N = 54. Intervention group participants received a 3-month behavioral support intervention, which consisted of two one-hour face-to-face counseling sessions and three follow-up counseling contacts by e-mail or telephone at weeks three, six and nine. PA counseling, delivered by qualified PA counselors, aimed to satisfy participants’ basic psychological needs for autonomy, competence, and relatedness. Reference group participants did not receive individualized PA counseling. Outcome measures included objectively assessed and self-reported PA and sedentary time and psychological need satisfaction. Assessments were held at baseline, immediately after the intervention (short-term and 6 months post-intervention (long-term. Mixed model analyses and bootstrapping analyses were used to determine intervention and mediation effects, respectively. Results The intervention group increased weekday daily steps both in the short- and long-term, while the reference group showed reductions in daily step count (ES = .65 and ES = .48 in the short- and long-term, respectively. In the short-term, weekday moderate-to-vigorous PA increased more pronouncedly in the intervention group compared to the reference group (ES = .34. Moreover, the intervention group demonstrated reductions in self-reported sitting time during weekends both in the short- and long-term, whereas the reference group reported

Free-living amoebae (FLA) are common components of microbial communities in drinking water distribution systems (DWDS). FLA are of clinical importance both as pathogens and as reservoirs for bacterial pathogens, so identifying the conditions promoting amoebae colonisation of DWDSs is an important public health concern for water utilities. We used high-throughput amplicon sequencing to compare eukaryotic and bacterial communities associated with DWDS biofilms supporting distinct FLA species (Naegleria fowleri, N. lovaniensis or Vermamoeba sp.) at sites with similar physical/chemical conditions. Eukaryote and bacterial communities were characteristics of different FLA species presence, and biofilms supporting Naegleria growth had higher bacterial richness and higher abundance of Proteobacteria, Bacteroidetes (bacteria), Nematoda and Rotifera (eukaryota). The eukaryotic community in the biofilms had the greatest difference in relation to the presence of N. fowleri, while the bacterial community identified individual bacterial families associated with the presence of different Naegleria species. Our results demonstrate that ecogenomics data provide a powerful tool for studying the microbial and meiobiotal content of biofilms, and, in these samples can effectively discriminate biofilm communities supporting pathogenic N. fowleri. The identification of microbial species associated with N. fowleri could further be used in the management and control of N. fowleri in DWDS. © FEMS 2017. All rights reserved.

Using individual two-posterior short implants with two-anterior standard implants in mandibular implant-supported-overdenture to enhance the patient satisfaction: A clinical report

Directory of Open Access Journals (Sweden)

Mehran Bahrami

2017-01-01

Full Text Available Introduction: Many clinical cases and the literature review have revealed implant-supported-overdentures’ (ISOs treatment success and predictability in elderly patients. According to the previous studies, all the mandibular ISOs used 2–4 implants anterior to mental foramen to retain the denture. Case Report: In this clinical report, two individual anterior standard implants and two individual posterior short implants were used to support the mandibular ISO, as well as to prevent further posterior bone resorption. This treatment option permits the patient to insert more implants in the future, and could be upgraded to implant-supported-fixed prosthesis. Discussion: The patient was completely satisfied about the final result, especially for upgrading the mastication efficiency. The patient was followed-up for more than 2 years without complication. The panoramic X-ray showed the preserved bone in the posterior region. This technique could be considered to be innovative, and more clinical cases are required to be documented as a predictable modality.

This report summarizes the work performed under contract DOE-FCO2-84ER45162. During the past ten years, our study of electron emission from laser-illuminated field emission tips has taken on a broader scope by addressing problems of direct interest to those concerned with the unique physical and chemical properties of nanometer-size clusters. The work performed has demonstrated that much needed data can be obtained on individual nanometer-size clusters supported on a wide-variety of different substrates. The work was performed in collaboration with R.P. Andres in the School of Chemical Engineering at Purdue University. The Multiple Expansion Cluster Source developed by Andres and his students was essential for producing the nanometer-size clusters studied. The following report features a discussion of these results. This report provides a motivation for studying the properties of nanometer-size clusters and summarizes the results obtained.

Full Text Available Abstract The controversies surrounding transgenic crops, often called Genetically Modified Organisms (GMOs, call for a need to raise the level of public awareness of Genetic Modification (GM technology in Africa. This should be accomplished by educating the public about the potential benefits and risks that may be associated with this new technology. In the last 15 years, GM crop producing countries have benefited from adoption of this new technology in the form of improved crop productivity, food security, and quality of life. The increased income to resource-poor farmers is a key benefit at the individual level especially as most countries using this technology are in the developing world, including three African countries (South Africa, Burkina Faso and Egypt. Despite clear benefits to countries and farmers who grow GMOs, many people are concerned about suspected potential risks associated with GMOs. This sparks debate as to whether GM technology should be adopted or not. Given the concerns regarding the safety of GMO products, thorough scientific investigation of safe application of GMOs is required. The objective of this paper is to respond to the issues of GM agriculture in Africa and some of the issues surrounding the adoption of GM crops between developed and developing countries.

Das, Smita; Prochaska, Judith J

2017-10-01

Tobacco remains the leading preventable cause of death in the US, accounting for over 520,000 deaths annually. While the smoking prevalence has declined over the past 50 years, those with mental illness and addictive disorders continue to smoke at high levels and with significant tobacco-related health problems. Areas covered: This review highlights the epidemiology, contributing factors, and evidence-base for intervening upon tobacco use in those with mental illness and addictive disorders. Historically underprioritized, a growing body of literature supports treating tobacco within mental health and addiction treatment settings. Critically, treating tobacco use appears to support, and not harm, mental health recovery and sobriety. This review also summarizes novel, emerging approaches to mitigate the harms of cigarette smoking. Expert commentary: People with mental illness and addictive disorders have a high prevalence of tobacco use with serious health harms. Treating tobacco use is essential. Evidence-based strategies include individual treatments that are stage-matched to readiness to quit and combine cessation medications with behavioral therapies, supported by smoke-free policies in treatment settings and residential environments. Emerging approaches, with a focus on harm reduction, are electronic nicotine delivery systems and tobacco regulatory efforts to reduce the nicotine content in cigarettes, thereby reducing their addiction potential.

Full Text Available BACKGROUND: To determine The Medical Technology Vocational Training School (MTVTS students’ the knowledge about the effects of GMO on human health and environment and to evaluate their attitude and behavior has been aimed. METHODS: All of the second class students of the year 2006-2007 of MTVTS were included (N=161 in the study, response rate was 92%. The survey questionare included questions on knowledge, the risk perception and attitute about GMOs. The legal framework in Turkey about GMOs, the rationale for GMO production, the labeling for GMO and the students’ perception of their knowledge was evaluated through 14 items with Likert scale. After the questionaire, the students received an informative brochure on GMOs. RESULTS: The open-ended question asking to define GMOs was answered by 59,2% of the students among which 35,6% defined as “additive”, 34,5% as “food with hormones”. The risk perceived for GMOs was the forth following cigarette smoking, stres, and environmental pollution in the ranking according to the risk score means. Sex has been the only determinant effecting this scoring for GMOs where girls perceived the risk greater. If family was one of the information sources about GMOs, the perceived risk was increased (p=0,000. Among the students 81,6% thought that GMO should not be grown in Turkey, 77,7% think that GMO was sold however. The leading topic of ambivalence is the state of self knowledge on GMO. The low income group are less concerned about consuming GMO for themselves or for their children (respectively p==0.003 ve p=0,012. CONCLUSION: Health workers are assigned with an important role to inform the public for healthy eating. However although the the risk perception of the study group for GMOs is high, their knowledge is low. Training activities to supply this deficiency should be implemented.

This paper examines the literature on the use of functional communication training (FCT) as a treatment for problem behavior displayed by individuals with intellectual disabilities (ID). Criteria for empirically supported treatments developed by Divisions 12 and 16 of the American Psychological Association (Kratochwill & Stoiber, 2002; Task Force, 1995) and adapted by Jennett and Hagopian (2008) for evaluation of single-case research studies were used to examine the support for FCT. Results indicated that FCT far exceeds criteria to be designated as a well-established treatment for problem behavior exhibited by children with ID and children with autism spectrum disorder, and can be characterized as probably efficacious with adults.

To examine the relevance of social skills and their different dimensions (ie, expressivity, sensitivity, control) in relation to social support, depression, participation, and quality of life (QOL) in individuals with spinal cord injury (SCI). Cross-sectional data collection within the Swiss Spinal Cord Injury Cohort. Community-based. Individuals with SCI (N=503). Not applicable. Depression, participation, and QOL were measured using the Hospital Anxiety and Depression Scale, the Utrecht Scale for Evaluation of Rehabilitation-Participation, and 5 selected items of the World Health Organization Quality of Life Scale. The Social Skills Inventory and the Social Support Questionnaire were used to assess social skills (expressivity, sensitivity, control) and social support, respectively. Structural equation modeling was conducted. In model 1 (χ(2)=27.81; df=19; P=.087; root mean square error of approximation=.033; 90% confidence interval=.000-.052), social skills as a latent variable was related to social support (β=.31; R(2)=.10), depression (β=-.31; total R(2)=.42), and QOL (β=.46; R(2)=.25). Social support partially mediated the effect of social skills on QOL (indirect effect: β=.04; P=.02) but not on depression or participation. In model 2 (χ(2)=27.96; df=19; P=.084; root mean square error of approximation=.031; 90% confidence interval=.000-.053), the social skills dimension expressivity showed a path coefficient of β=.20 to social support and β=.18 to QOL. Sensitivity showed a negative path coefficient to QOL (β=-.15) and control a path coefficient of β=-.15 to depression and β=.24 to QOL. Social skills are a resource related to more social support, lower depression scores, and higher QOL. Copyright © 2015 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Human breath analysis may support the existence of individual metabolic phenotypes.

Directory of Open Access Journals (Sweden)

Pablo Martinez-Lozano Sinues

Full Text Available The metabolic phenotype varies widely due to external factors such as diet and gut microbiome composition, among others. Despite these temporal fluctuations, urine metabolite profiling studies have suggested that there are highly individual phenotypes that persist over extended periods of time. This hypothesis was tested by analyzing the exhaled breath of a group of subjects during nine days by mass spectrometry. Consistent with previous metabolomic studies based on urine, we conclude that individual signatures of breath composition exist. The confirmation of the existence of stable and specific breathprints may contribute to strengthen the inclusion of breath as a biofluid of choice in metabolomic studies. In addition, the fact that the method is rapid and totally non-invasive, yet individualized profiles can be tracked, makes it an appealing approach.

Supporting the Support System: How Assessment and Communication Can Help Patients and Their Support Systems.

Science.gov (United States)

Harkey, Jane; Young, Jared; Carter, Jolynne Jo; Demoratz, Michael

The benefits of having a support system, such as social relationships with close friends and family, have been well documented for patients with serious health issues. As scientific evidence has shown, individuals who have the lowest level of involvement in social relationships face a greater mortality risk. Support systems, however, are not infallible. Relationship stress can have a negative impact on people-patient and caregiver alike-behaviorally, psychosocially, and physiologically. The purpose of this article is to encourage case managers who take a patient-centered approach to also consider the existence and extent of the support system, as well as any stresses or tensions that are observable within the support system. Although the case manager is ethically obliged to advocate for the individual receiving case management services, that advocacy can be extended to the support system for the good of all. This discussion applies to numerous case management practices and work settings including (but not limited to) hospital-based case management, home health, geriatrics, catastrophic case management, mental health, palliative care, and end of life/hospice. As part of the assessment phase of the case management process, case managers determine the extent of the patient's support system or social support network such as family and close friends. Although their advocacy is primarily for the patient receiving case management services, case managers also become aware of the needs of the support system members as they face their loved one's serious illness, severe injury, geriatric care demands, or end of life. Case managers can use their communication skills, especially motivational interviewing, with patients and their support systems to identify stresses and issues that can impact the pursuit of health goals. In addition, case managers ensure that individuals and their support systems are kept informed such as about the health condition, stage of disease, plan of

Spiritual care means helping an individual protect, maintain and gain all the dimensions of his/her existence. Elderly care technicians face numerous cases or crisis situations in which elderly individuals from different backgrounds question the meaning and value of life. Elderly care technicians must acknowledge that the spirituality is an important element in the way an elderly individual receives healthcare and they must be equipped for this matter. This study was conducted in order to examine the influence of "Skill Development Training Program for Spiritual Care of Elderly Individual," which was carried out with students from elderly care program, on the perception of spirituality support in a pretest-posttest quasi-experimental study design with control group. As the data collection form, "Spiritual Support Perception" (SSP) scale was used. The mean scores of the intervention group after the training and after one month are 50.39 ± 5.34 and 51.13 ± 4.98, respectively, and those of the control group are 43.16 ± 4.83 and 42.72 ± 4.48. A statistically significant difference was found between the mean scores of the intervention group from the pretest and the posttests immediately after the training and one month after the training (f = 94.247, p = 0.001). In the control group, however, there was no significant change in the SSP mean scores (f = 0.269, p = 0.77). As a result, this study pointed out the necessity of such training programs for healthcare professionals to make a distinction between their professional duties and their own personalities in order to offer spiritual care to the elderly individual.

Additional Interventions to Enhance the Effectiveness of Individual Placement and Support: A Rapid Evidence Assessment

Naomi Boycott

2012-01-01

Full Text Available Topic. Additional interventions used to enhance the effectiveness of individual placement and support (IPS. Aim. To establish whether additional interventions improve the vocational outcomes of IPS alone for people with severe mental illness. Method. A rapid evidence assessment of the literature was conducted for studies where behavioural or psychological interventions have been used to supplement standard IPS. Published and unpublished empirical studies of IPS with additional interventions were considered for inclusion. Conclusions. Six published studies were found which compared IPS alone to IPS plus a supplementary intervention. Of these, three used skills training and three used cognitive remediation. The contribution of each discrete intervention is difficult to establish. Some evidence suggests that work-related social skills and cognitive training are effective adjuncts, but this is an area where large RCTs are required to yield conclusive evidence.

Full Text Available The safety of genetically modified organisms (GMOs has attracted much attention recently. Polymerase chain reaction (PCR amplification is a common method used in the identification of GMOs. However, a major disadvantage of PCR is the potential amplification of non-target DNA, causing false-positive identification. Thus, there remains a need for a simple, reliable and ultrasensitive method to identify and quantify GMO in crops. This report is to introduce a magnetic bead-based PCR-free method for rapid detection of GMOs using dual-color fluorescence cross-correlation spectroscopy (FCCS. The cauliflower mosaic virus 35S (CaMV35S promoter commonly used in transgenic products was targeted. CaMV35S target was captured by a biotin-labeled nucleic acid probe and then purified using streptavidin-coated magnetic beads through biotin-streptavidin linkage. The purified target DNA fragment was hybridized with two nucleic acid probes labeled respectively by Rhodamine Green and Cy5 dyes. Finally, FCCS was used to detect and quantify the target DNA fragment through simultaneously detecting the fluorescence emissions from the two dyes. In our study, GMOs in genetically engineered soybeans and tomatoes were detected, using the magnetic bead-based PCR-free FCCS method. A detection limit of 50 pM GMOs target was achieved and PCR-free detection of GMOs from 5 microg genomic DNA with magnetic capture technology was accomplished. Also, the accuracy of GMO determination by the FCCS method is verified by spectrophotometry at 260 nm using PCR amplified target DNA fragment from GM tomato. The new method is rapid and effective as demonstrated in our experiments and can be easily extended to high-throughput and automatic screening format. We believe that the new magnetic bead-assisted FCCS detection technique will be a useful tool for PCR-free GMOs identification and other specific nucleic acids.

Successful competitive employment has been found to be related to enhanced self-esteem, higher quality of life and reduced mental health service use for individuals living with serious mental illnesses (SMIs) including schizophrenia, bipolar disorder and major depression. The effectiveness of the individual placement and support model has been demonstrated in multiple randomised controlled trials in many countries. The management of stress, depression and anxiety in the workplace may be effectively enhanced through digital mental health interventions. The WorkingWell mobile support tool ('app') is specifically designed to meet the need for illness management support for individuals with SMI in the workplace, as an adjunct to professional treatment. The WorkingWell app, grounded in evidence-based supported employment, is informed by user experience design. It will be tested in a pre-post design, mixed-methods pilot study to explore issues of feasibility, acceptability and usefulness, and to provide preliminary data on the impact of use. Putative mediators of improved job tenure and psychological well-being, including postintervention changes in social support, self-efficacy and work-related motivation, will be investigated. Forty individuals at least 18 years of age, meeting the eligibility requirements for supported employment services (ie, diagnosed with a mental illness meeting the criteria for severity, duration and treatment), working a minimum of 10 hours per week at study enrolment, and speaking, reading and writing in English will be recruited for the pilot study. Research staff will recruit individuals at community-based mental health agencies; provide orientation to the study, the study smartphones and the WorkingWell app; conduct research interviews including standardised measures as well as semistructured items; and provide technical assistance in telephone calls and inperson meetings. A sample of 10 agency staff will be recruited to obtain further

Tuning the electronic properties and Schottky barrier height of the vertical graphene/MoS2 heterostructure by an electric gating

2018-04-01

In this paper, the electronic properties and Schottky contact in graphene/MoS2 (G/MoS2) heterostructure under an applied electric field are investigated by means of the density functional theory. It can be seen that the electronic properties of the G/MoS2 heterostructure are preserved upon contacting owing to the weak van der Waals interaction. We found that the n-type Schottky contact is formed in the G/MoS2 heterostructure with the Schottky barrier height of 0.49 eV. Furthermore, both Schottky contact and Schottky barrier height in the G/MoS2 heterostructure could be controlled by the applied electric field. If a positive electric field of 4 V/nm is applied to the system, a transformation from the n-type Schottky contact to the p-type one was observed, whereas the system keeps an n-type Schottky contact when a negative electric field is applied. Our results may provide helpful information to design, fabricate, and understand the physics mechanism in the graphene-based two-dimensional van der Waals heterostructures like as G/MoS2 heterostructure.

Genetically modified organisms (GMOs) are increasingly deployed at large scales and in open environments. Genetic biocontainment strategies are needed to prevent unintended proliferation of GMOs in natural ecosystems. Existing biocontainment methods are insufficient because they impose evolutionary pressure on the organism to eject the safeguard by spontaneous mutagenesis or horizontal gene transfer, or because they can be circumvented by environmentally available compounds. Here we computationally redesign essential enzymes in the first organism possessing an altered genetic code (Escherichia coli strain C321.ΔA) to confer metabolic dependence on non-standard amino acids for survival. The resulting GMOs cannot metabolically bypass their biocontainment mechanisms using known environmental compounds, and they exhibit unprecedented resistance to evolutionary escape through mutagenesis and horizontal gene transfer. This work provides a foundation for safer GMOs that are isolated from natural ecosystems by a reliance on synthetic metabolites.

To determine the effects of a 24-month program of Individual Placement and Support (IPS) supported employment (SE) on employment outcomes for veterans with spinal cord injury (SCI). Longitudinal, observational multisite study of a single-arm, nonrandomized cohort. SCI centers in the Veterans Health Administration (n=7). Veterans with SCI (N=213) enrolled during an episode of either inpatient hospital care (24.4%) or outpatient care (75.6%). More than half the sample (59.2%) had a history of traumatic brain injury (TBI). IPS SE for 24 months. Competitive employment. Over the 24-month period, 92 of 213 IPS participants obtained competitive jobs for an overall employment rate of 43.2%. For the subsample of participants without TBI enrolled as outpatients (n=69), 36 obtained competitive jobs for an overall employment rate of 52.2%. Overall, employed participants averaged 38.2±29.7 weeks of employment, with an average time to first employment of 348.3±220.0 days. Nearly 25% of first jobs occurred within 4 to 6 months of beginning the program. Similar employment characteristics were observed in the subsample without TBI history enrolled as outpatients. Almost half of the veterans with SCI participating in the 24-month IPS program as part of their ongoing SCI care achieved competitive employment, consistent with their expressed preferences at the start of the study. Among a subsample of veterans without TBI history enrolled as outpatients, employment rates were >50%. Time to first employment was highly variable, but quite long in many instances. These findings support offering continued IPS services as part of ongoing SCI care to achieve positive employment outcomes. Copyright © 2017 American Congress of Rehabilitation Medicine.

2009-01-01

We present Integral Field Unit GMOS-IFU data of the compact H II galaxy UM 408, obtained at the Gemini South telescope, in order to derive the spatial distribution of emission lines and line ratios, kinematics, plasma parameters, and oxygen abundances as well the integrated properties over an area of 3''x4.''4 equivalent with ∼750 pc x 1100 pc located in the central part of the galaxy. The starburst in this area is resolved into two giant regions of about 1.''5 and 1'' (∼375 and ∼250 pc) diameter, respectively and separated 1.5-2'' (∼500 pc). The extinction distribution concentrate its highest values close but not coincident with the maxima of Hα emission around each one of the detected regions. This indicates that the dust has been displaced from the exciting clusters by the action of their stellar winds. The ages of these two regions, estimated using Hβ equivalent widths, suggest that they are coeval events of ∼5 Myr with stellar masses of ∼10 4 M sun . We have also used [O III]/Hβ and [S II]/Hα ratio maps to explore the excitation mechanisms in this galaxy. Comparing the data points with theoretical diagnostic models, we found that all of them are consistent with excitation by photoionization by massive stars. The Hα emission line was used to measure the radial velocity and velocity dispersion. The heliocentric radial velocity shows an apparent systemic motion where the east part of the galaxy is blueshifted, while the west part is redshifted, with a relative motion of ∼10 km s -1 . The velocity dispersion map shows supersonic values typical for extragalactic H II regions. We derived an integrated oxygen abundance of 12+log(O/H) = 7.87 summing over all spaxels in our field of view. An average value of 12+log(O/H) = 7.77 and a difference of Δ(O/H) = 0.47 between the minimum and maximum values (7.58 ± 0.06-8.05 ± 0.04) were found, considering all data points where the oxygen abundance was measured. The spatial distribution of oxygen abundance

Genetically modified organisms (GMOs) provide modern agriculture with improvements in efficiency and the benefits of enhanced food production; however, the potential impact of GMOs on human health has not yet been clarified. To investigate the allergenicity of isopentenyltransferase (ipt)-transformed broccoli compared with non-GM broccoli. Sera from allergic individuals were used to identify the allergenicity of GM and non-GM broccoli. Immunoglobulin (Ig) binding of different lines of GM and non-GM broccoli was identified using immunoblotting, enzyme-linked immunosorbent assay, and the histamin release assay. Positive reactions to broccoli (Brassica Oleracea) were observed in 7.02% of individuals. Specific IgE to broccoli and total IgE fro allergic individuals were well correlated. The different tests performed showed no significant differences in the allergenicity of conventionally raised and GM broccoli, indicating the absence of unexpected effects on allergenicity in ipt-transformed plants. Using Western blot analysis we detected heterogeneous IgE-reactive allergenic components in broccoli-allergic sera, but no significant differences between GM an non-GM broccoli were observed in serum from the same patients. Our study demonstrates that there are no differences between GM (ipt-transformed) broccoli and non-GM broccoli, as determined by specific IgE in sera from broccoli-allergic patients. This indicates that there were no unexpected effects on allergenicity in this GM broccoli.

The target of every company is to satisfy customer demands. Especially the clothing industry has to serve individual customer requirements. Textile products always have been and still are the defining attributes of people’s appearance. Consumer’s demands towards commercial clothing companies have been changing rapidly during the recent years. Two global megatrends have supported this change: Individualization and digitalization. Individualization created demand for frequent collection changes, while still keeping availability high. Digitalization supported the quick distribution of new trends and forced a higher amount of request during peak periods. This paper outlines how a highly individual and customizable fashion product can be produced in a store environment. It focuses on the conceptual design, taking into account the interdisciplinary approach combining production technology with IT-systems, but also addresses the economical challenge with help of a value stream analysis.

Quantitative analysis of food and feed samples with droplet digital PCR.

Full Text Available In this study, the applicability of droplet digital PCR (ddPCR for routine analysis in food and feed samples was demonstrated with the quantification of genetically modified organisms (GMOs. Real-time quantitative polymerase chain reaction (qPCR is currently used for quantitative molecular analysis of the presence of GMOs in products. However, its use is limited for detecting and quantifying very small numbers of DNA targets, as in some complex food and feed matrices. Using ddPCR duplex assay, we have measured the absolute numbers of MON810 transgene and hmg maize reference gene copies in DNA samples. Key performance parameters of the assay were determined. The ddPCR system is shown to offer precise absolute and relative quantification of targets, without the need for calibration curves. The sensitivity (five target DNA copies of the ddPCR assay compares well with those of individual qPCR assays and of the chamber digital PCR (cdPCR approach. It offers a dynamic range over four orders of magnitude, greater than that of cdPCR. Moreover, when compared to qPCR, the ddPCR assay showed better repeatability at low target concentrations and a greater tolerance to inhibitors. Finally, ddPCR throughput and cost are advantageous relative to those of qPCR for routine GMO quantification. It is thus concluded that ddPCR technology can be applied for routine quantification of GMOs, or any other domain where quantitative analysis of food and feed samples is needed.

We use integral field spectroscopic (IFS) observations from the Gemini Multi-Object Spectrograph North (GMOS-N) to study the central H II region in a nearby blue compact dwarf (BCD) galaxy NGC 4449. The IFS data enable us to explore the variation of physical and chemical conditions of the star-forming region and the surrounding gas on spatial scales as small as 5.5 pc. Our kinematical analysis shows possible signatures of shock ionization and shell structures in the surroundings of the star-forming region. The metallicity maps of the region, created using direct Te and indirect strong line methods (R23, O3N2 and N2), do not show any chemical variation. From the integrated spectrum of the central H II region, we find a metallicity of 12 + log(O/H) = 7.88 ± 0.14 ({˜ }0.15^{+0.06}_{-0.04} Z⊙) using the direct method. Comparing the central H II region metallicity derived here with those of H II regions throughout this galaxy from previous studies, we find evidence of increasing metallicity with distance from the central nucleus. Such chemical inhomogeneities can be due to several mechanisms, including gas loss via supernova blowout, galactic winds or metal-poor gas accretion. However, we find that the localized area of decreased metallicity aligns spatially with the peak of star-forming activity in the galaxy, suggesting that gas accretion may be at play here. Spatially resolved IFS data for the entire galaxy are required to confirm the metallicity inhomogeneity found in this study and determine its possible cause.

The Greater Yellowstone Ecosystem (GYE) supports the southernmost of the 2 largest remaining grizzly bear (Ursus arctos) populations in the contiguous United States. Since the mid-1980s, this population has increased in numbers and expanded in range. However, concerns for its long-term genetic health remain because of its presumed continued isolation. To test the power of genetic methods for detecting immigrants, we generated 16-locus microsatellite genotypes for 424 individual grizzly bears sampled in the GYE during 1983–2007. Genotyping success was high (90%) and varied by sample type, with poorest success (40%) for hair collected from mortalities found ≥1 day after death. Years of storage did not affect genotyping success. Observed heterozygosity was 0.60, with a mean of 5.2 alleles/marker. We used factorial correspondence analysis (Program GENETIX) and Bayesian clustering (Program STRUCTURE) to compare 424 GYE genotypes with 601 existing genotypes from grizzly bears sampled in the Northern Continental Divide Ecosystem (NCDE) (FST  =  0.096 between GYE and NCDE). These methods correctly classified all sampled individuals to their population of origin, providing no evidence of natural movement between the GYE and NCDE. Analysis of 500 simulated first-generation crosses suggested that over 95% of such bears would also be detectable using our 16-locus data set. Our approach provides a practical method for detecting immigration in the GYE grizzly population. We discuss estimates for the proportion of the GYE population sampled and prospects for natural immigration into the GYE.

To determine the prevalence and the factors related to sick leave and job loss among individuals suffering from chronic pain (CP), and to analyse specifically the effect of family and social support on the individual's employment. Observational cross-sectional study. Data were collected using structured computer-assisted telephone interviews between February and June 2011. A nationwide study of 1543 Spanish adults of working age (families, and their satisfaction with the family and social support. To identify factors associated with sick leave and job loss among those suffering CP, 2 logistic regression models were generated. The prevalence of sick leave due to CP in the general Spanish population was 4.21% (95% CI 3.2% to 5.2%). Sick leave were more likely for individuals who considered their family were affected by their pain (OR=2.18), needed help to dressing and grooming (OR=2.98), taking medication (OR=2.18), had a shorter pain duration (OR=0.99) and higher educational level. The prevalence of job loss due to CP was 1.8% (95% CI 1.1% to 2.5%). It was related to feelings of sadness (OR=4.25), being unsatisfied with the care provided by health professionals (OR=2.60) and consulting a doctor more often due to CP (OR=1.09). CP is negatively associated with an individual's employment. This detrimental effect could be ameliorated if the factors related to sick leave and job loss provoked by CP are identified, especially those related to the effect of CP on the family and social environment.

Virtual environments (VEs) facilitate interaction and support among individuals with chronic illness, yet the characteristics of these VE interactions remain unknown. The objective of this study was to describe social interaction and support among individuals with type 2 diabetes (T2D) who interacted in a VE. Data included VE-mediated synchronous conversations and text-chat and asynchronous emails and discussion board posts from a study that facilitated interaction among individuals with T2D and diabetes educators (N=24) in 2 types of sessions: education and support. VE interactions consisted of communication techniques (how individuals interact in the VE), expressions of self-management (T2D-related topics), depth (personalization of topics), and breadth (number of topics discussed). Individuals exchanged support more often in the education (723/1170, 61.79%) than in the support (406/1170, 34.70%) sessions or outside session time (41/1170, 3.50%). Of all support exchanges, 535/1170 (45.73%) were informational, 377/1170 (32.22%) were emotional, 217/1170 (18.55%) were appraisal, and 41/1170 (3.50%) were instrumental. When comparing session types, education sessions predominately provided informational support (357/723, 49.4%), and the support sessions predominately provided emotional (159/406, 39.2%) and informational (159/406, 39.2%) support. VE-mediated interactions resemble those in face-to-face environments, as individuals in VEs engage in bidirectional exchanges with others to obtain self-management education and support. Similar to face-to-face environments, individuals in the VE revealed personal information, sought information, and exchanged support during the moderated education sessions and unstructured support sessions. With this versatility, VEs are able to contribute substantially to support for those with diabetes and, very likely, other chronic diseases. ©Allison A Lewinski, Ruth A Anderson, Allison A Vorderstrasse, Edwin B Fisher, Wei Pan, Constance

Full Text Available The assessment and risk management of GMOs are inherited from the paradigm of molecular biology born in the 1960s and from theories of evolutionary biology dominant in the years that saw the onset of GMOs. But these paradigms have been greatly challenged by recent advances in these disciplines : the dissolution of the concept of gene, the identification of epigenetic phenomena transmitted hereditarily, the discovery of the new continent of microRNAs, the metapopulation theory, the ability to trace gene flow over long distances, imply otherwise consider the properties of a genetically modified organism, whether or not dedicated to the dispersion in the environment. A symposium organized last february in Paris, in the framework of the ANR GMOs was designed to take the measure of these transformations of the paradigms of biology and to let clear how these results force to rethink the impacts of GMOs in the light of the new biology.

Supplementing supported employment with workplace skills training.

Science.gov (United States)

Wallace, Charles J; Tauber, Robert

2004-05-01

Introduction by the column editors: Supported employment, as designed for persons with serious and persistent mental illness, has been termed individual placement and support. In two randomized controlled trials (1,2), clients who received individual placement and support services were more likely to obtain at least one job in the competitive sector, to work more hours, and to have a higher total income than their counterparts who received more traditional types of vocational rehabilitation. However, individual placement and support did not improve the length of time the employed participants kept their jobs. An adjunctive or additional element of individual placement and support, aimed at improving the job tenure of individuals with mental illness, would be a constructive contribution to the vocational rehabilitation for this population. In a previous Rehab Rounds column, Wallace and colleagues (3) described the development of the workplace fundamental skills module, a highly structured and user-friendly curriculum designed to teach workers with mental illness the social and workplace skills needed to keep their jobs. The workplace fundamental skills module supplements individual placement and support by conveying specific skills that enable workers to learn the requirements of their jobs, anticipate the stressors associated with their jobs, and cope with stressors by using a problem-solving process. The earlier report described the production and validation of the module's content. The purpose of this month's column is to present the preliminary results of a randomized comparison of the module's effects on job retention, symptoms, and community functioning when coupled with individual placement and support. To enable wide generalization of the findings of the study, the program was conducted in a typical community mental health center.

The bacterial reverse mutation test, commonly called Ames test, is used worldwide. In Japan, the genetically modified organisms (GMOs) are regulated under the Cartagena Domestic Law, and organisms obtained by self-cloning and/or natural occurrence would be exempted from the law case by case. The strains of Salmonella typhimurium and Escherichia coli recommended for use in the bacterial reverse mutation test (OECD guideline 471), have been considered as non-GMOs because they can be constructed by self-cloning or naturally occurring bacterial strains, or do not disturb the biological diversity. The present article explains the reasons why these tester strains should be classified as non-GMOs.

Nesse trabalho é apresentado um estudo do conteúdo de massa do aglomerado de galáxias A586 (z = 0.171) bem como sua distribuição espacial. Isso foi feito a partir de dados de espectroscopia multi-objeto e imageamento obtidos com o instrumento GMOS acoplado ao telescópio Gemini-Norte. A massa desse aglomerado foi estudada a partir da posição dos seus arcos gravitacionais (lentes fortes), da medida estatística da distorção na forma das galáxias de fundo (lentes fracas) e através da dispersão de velocidades de uma amostra de cerca de 30 galáxias pertencentes ao aglomerado (teorema do virial). Os dois primeiros métodos não dependem do estado dinâmico do aglomerado, enquanto que o terceiro sim. Desse modo, comparando seus resultados pode-se estimar o grau de relaxamento desse sistema. Dados de raios X presentes na literatura também serão incluídos nessa análise. Nossos resultados preliminares a partir das técnicas de lentes fracas, mostram que, supondo que a distribuição de massa desse aglomerado seja a de uma esfera isotérmica, espera-se que ele apresente uma dispersão de velocidades de 1330+/-78 km s-1, em contradicao com medidas similares feitas por Dahle et al. 2002 que encontram valores tão altos quanto 1680 km s-1. Já o estudo dinâmico resultou numa dispersão de velocidades de ~950 km s-1.

Ferreira, Ronél; Ebersöhn, Liesel

The article describes the pilot phase of a participatory reflection and action (PRA) study. The longitudinal investigation explores teachers' ability to provide psychosocial support within the context of HIV/AIDS following an asset-based intervention. The study ensued from our desire to understand and contribute to knowledge about the changed roles of teachers due to adversity in the community, specifically in relation to HIV/AIDS and education. The supportive teachers, assets and resilience (STAR) intervention was facilitated from November 2003 to October 2005 and consisted of the research team undertaking nine field visits and facilitating 20 intervention sessions (2-3 hours each), and 12 post-intervention research visits have been conducted to date. Ten female teachers were selected for participation through random purposeful sampling at a primary school in an informal settlement outside Port Elizabeth, South Africa. Data-generation included PRA activities, observation, informal interactive interviews, and focus group discussions. The data were analysed by means of inductive thematic analysis. We found that the teachers did not view vulnerability as being related to children or HIV/AIDS in isolation, but rather that their psychosocial support to children and the school community was inclusive across a spectrum of vulnerabilities and services. We argue that teachers who are inclined to provide such support will fulfil this role irrespective of understanding policy or receiving training. We contend that teachers are well-positioned to manage school-based psychosocial support in order to create relevant and caring spaces for vulnerable individuals in the school community.

Socioeconomic status of mothers, family economic pressure, and mothers' exposure to stress were measured. Special attention was given to the perceived availability of social support as one of protective factors potentially buffering the negative impact of risks of child abuse. The community sample included 746 mothers (Mage = 42.85; SDage = 5.319). The results showed that the risk of child abuse is higher for mothers with lower education, those who perceive themselves as suffering greater family economic hardship, those who have experienced a higher number of stressful events, and those with lower social support. When the mothers perceive a lower availability of social support, the effects of exposure to cumulative risk, namely the combination of socioeconomic status, economic pressure, and exposure to stress, are stronger. Since social support proved to be one of the key protective factors in the relationship between adverse life circumstances and parenting, the development of effective and non-stigmatized interventions aiming to increase social support, positive social relationships, and adequate parenting practices for parents facing economic hardship is an important direction for future family policy measures.

Creative art has been found to be beneficial to some patients with chronic illness. Little is understood about how creative art can benefit individuals living with multiple sclerosis (MS). The purpose of the pilot study was to determine if there was a difference in self-esteem, hope, perceived social support, and self-efficacy in individuals with MS after a 4-week creative art program. A one-group, pretest/posttest design was used. The convenience sample of 14 individuals was recruited from MS Centers and the National MS Society. They ranged in age from 29 to 70 years (M = 51.3 years, SD = 12.5 years). Participants included 14 women. The creative art program included week 1-watercolor, week 2-collage making, week 3-beading, and week 4-knitting. Each of the four weekly sessions was facilitated by a registered nurse with expertise in MS and lasted 2 hours. Creative artists instructed participants and provided a hands-on experience for each of the creative projects. Participants were free to share thoughts, experiences, and words of support and encouragement during each session. The variables were measured before starting the creative art program and after the final session. The instruments included the Rosenberg Self-Esteem Scale, the Herth Hope Index, the Modified Social Support Survey, the MS Self-Efficacy Scale, and a sociodemographic questionnaire. The Statistical Package for the Social Sciences Version 16.0 was used to analyze the data. There was a significant increase in all variables after the creative art program as follows: self-esteem (t = -3.05, p = 009), hope (t = -3.96, p = .002), social support (t = -2.21, p = .046), self-efficacy to function with MS (t = -2.68, p = .019), and self-efficacy to control MS (t = 3.22, p = .007). The power analysis revealed a large effect size for hope (d = 1.06), self-esteem (d = 0.82), and self-efficacy (control; d = 0.86). A medium effect size was found for self-efficacy (function; d = 0.72) and social support (d = 0

Individual differences in behavioural plasticities.

Stamps, Judy A

2016-05-01

Interest in individual differences in animal behavioural plasticities has surged in recent years, but research in this area has been hampered by semantic confusion as different investigators use the same terms (e.g. plasticity, flexibility, responsiveness) to refer to different phenomena. The first goal of this review is to suggest a framework for categorizing the many different types of behavioural plasticities, describe examples of each, and indicate why using reversibility as a criterion for categorizing behavioural plasticities is problematic. This framework is then used to address a number of timely questions about individual differences in behavioural plasticities. One set of questions concerns the experimental designs that can be used to study individual differences in various types of behavioural plasticities. Although within-individual designs are the default option for empirical studies of many types of behavioural plasticities, in some situations (e.g. when experience at an early age affects the behaviour expressed at subsequent ages), 'replicate individual' designs can provide useful insights into individual differences in behavioural plasticities. To date, researchers using within-individual and replicate individual designs have documented individual differences in all of the major categories of behavioural plasticities described herein. Another important question is whether and how different types of behavioural plasticities are related to one another. Currently there is empirical evidence that many behavioural plasticities [e.g. contextual plasticity, learning rates, IIV (intra-individual variability), endogenous plasticities, ontogenetic plasticities) can themselves vary as a function of experiences earlier in life, that is, many types of behavioural plasticity are themselves developmentally plastic. These findings support the assumption that differences among individuals in prior experiences may contribute to individual differences in behavioural

The overall goal of the on-going Global Mercury Observation System (GMOS) project is to develop a coordinated global monitoring network for mercury, including ground-based, high altitude and sea level stations. In order to ensure data reliability and comparability, a significant effort has been made to implement a centralized system, which is designed to quality assure and quality control atmospheric mercury datasets. This system, GMOS-Data Quality Management (G-DQM), uses a web-based approach with real-time adaptive monitoring procedures aimed at preventing the production of poor-quality data. G-DQM is plugged on a cyberinfrastructure and deployed as a service. Atmospheric mercury datasets, produced during the first-three years of the GMOS project, are used as the input to demonstrate the application of the G-DQM and how it identifies a number of key issues concerning data quality. The major issues influencing data quality are presented and discussed for the GMOS stations under study. Atmospheric mercury data collected at the Longobucco (Italy) station is used as a detailed case study.

Full Text Available This paper aims to understand how certain different but interrelated variables such as background, motivation, and social support could lead to an explanation of student attitudes towards math and to an understanding of the defining characteristics of these attitudes in the school environment. Participants consisted of 1719 Portuguese students, from fifth-to-twelfth grade. The study utilizes an adaptation of the “Intrinsic Motivation Inventory” assessing main determinants of intrinsic motivation. One section of the questionnaire—“In my Math Class”—also assesses student perceptions of teacher and peer support as well as student attitudes. The results revealed that, in general, students held positive attitudes towards mathematics and also highlighted the main effects of grade and math achievement on these attitudes. No gender effect was identified although the girls showed a continuous decline in attitudes the further they progressed in school. A hierarchical analysis using structural equation modeling showed that motivation-related variables are the main predictors of attitudes towards mathematics and that teachers and the social support of peers are also highly significant in understanding these attitudes.

Recommendations from a meeting on health implications of genetically modified organism (GMO).

The Ghana Public Health Association organized a scientific seminar to examine the introduction of genetically modified organisms into public use and the health consequences. The seminar was driven by current public debate on the subject. The seminar identified some of the advantages of GMOs and also the health concerns. It is clear that there is the need to enhance local capacity to research the introduction and use of GMOs; to put in place appropriate regulatory mechanisms including particularly the labeling of GMO products and post-marketing surveillance for possible negative health consequences in the long term. Furthermore the appropriate state agency should put in place advocacy strategies to keep the public informed about GMOs.

When applying risk assessment and the broader process of risk analysis to decisions regarding the dissemination of genetically modified organisms (GMOs), the process has a tendency to become remarkably complex. Further, as greater numbers of countries consider authorising the large-scale dissemination of GMOs, and as GMOs with more complex traits reach late stages of development, there has been increasing concern about the burden posed by the complexity of risk analysis. We present here an improved approach for GMO risk analysis that gives a central role to problem formulation. Further, the risk analysis strategy has been clarified and simplified in order to make rigorously scientific risk assessment and risk analysis more broadly accessible to diverse stakeholder groups.

What risk assessments of genetically modified organisms can learn from institutional analyses of public health risks.

The risks of genetically modified organisms (GMOs) are evaluated traditionally by combining hazard identification and exposure estimates to provide decision support for regulatory agencies. We question the utility of the classical risk paradigm and discuss its evolution in GMO risk assessment. First, we consider the problem of uncertainty, by comparing risk assessment for environmental toxins in the public health domain with genetically modified organisms in the environment; we use the specific comparison of an insecticide to a transgenic, insecticidal food crop. Next, we examine normal accident theory (NAT) as a heuristic to consider runaway effects of GMOs, such as negative community level consequences of gene flow from transgenic, insecticidal crops. These examples illustrate how risk assessments are made more complex and contentious by both their inherent uncertainty and the inevitability of failure beyond expectation in complex systems. We emphasize the value of conducting decision-support research, embracing uncertainty, increasing transparency, and building interdisciplinary institutions that can address the complex interactions between ecosystems and society. In particular, we argue against black boxing risk analysis, and for a program to educate policy makers about uncertainty and complexity, so that eventually, decision making is not the burden that falls upon scientists but is assumed by the public at large.

Análise dos aspectos institucionais da regulação de OGMs no Brasil: boas práticas de governança ambiental?

Full Text Available The release for the planting of Genetically Modified Organisms (GMOs is a controversial issue and requires care because it involves the country’s food security, the sovereignty of producers about seed use and the long-term potential environmental risks. Thus, it is important to analyze how the decision-making structures, both formal and informal, are established to address these issues, i.e. environmental governance of GMOs in Brazil, which is the purpose of this article. Among the good governance practices to be analyzed, we will be using the following parameters: popular participation in decision-making, and access to information and environmental justice. The following results were obtained: from the standpoint of public participation, there are flaws, as decision-makers have little social permeability, therefore CTNBio holds public hearings only by its own decision or by court order, which limits access to participation in the deliberation on GMOs. Regarding access to information, we also pointed out problems, as the Biosafety Information System has not been implemented. Environmental justice is inefficient since many cases of contamination of organic and conventional varieties by GMOs economically harm farmers, especially the first ones, who are at risk of losing their organic certification. Moreover, the decision on conducting environmental impact studies is determined by CTNBio, injuring principles that give this task to the organs of SISNAMA. We conclude therefore that the regulation of GMOs in Brazil does not have good environmental governance.

Commercialization of several genetically modified crops has been approved worldwide to date. Uniplex polymerase chain reaction (PCR)-based methods to identify these different insertion events have been developed, but their use in the analysis of all commercially available genetically modified organisms (GMOs) is becoming progressively insufficient. These methods require a large number of assays to detect all possible GMOs present in the sample and thereby the development of multiplex PCR systems using combined probes and primers targeted to sequences specific to various GMOs is needed for detection of this increasing number of GMOs. Here we report on the development of a multiplex real-time PCR suitable for multiple GMO identification, based on the intercalating dye SYBR Green I and the analysis of the melting curves of the amplified products. Using this method, different amplification products specific for Maximizer 176, Bt11, MON810, and GA21 maize and for GTS 40-3-2 soybean were obtained and identified by their specific Tm. We have combined amplification of these products in a number of multiplex reactions and show the suitability of the methods for identification of GMOs with a sensitivity of 0.1% in duplex reactions. The described methods offer an economic and simple alternative to real-time PCR systems based on sequence-specific probes (i.e., TaqMan chemistry). These methods can be used as selection tests and further optimized for uniplex GMO quantification.

Transboundary Movements of Genetically Modified Organisms and the Cartagena Protocol: Key Issues and Concerns

Directory of Open Access Journals (Sweden)

Odile J Lim Tung

2014-12-01

Full Text Available Biotechnology or the engineering of the genetic material of species can give way to avenues of possibilities for the benefit of people, fauna and flora but also has the potential of posing untold and undiscovered threats to human beings and other living organisms. One of the first attempts to legislate on international rules on biotechnology can be traced back to article 19 of the Convention on Biological Diversity (CBD in 1992. The CBD is indeed the first international legal instrument apart from the then European Community’s relevant directives to suggest that biotechnology is a matter of concern for the international community while providing a basis upon which more detailed procedures would be elaborated in the field of biosafety. While the CBD includes international rules on access to genetic resources, access to and the transfer of technology, the handling of biotechnology and the distribution of its benefits, it does not include a detailed regulation on genetically modified organisms (GMOs and their possible adverse effects on the environment, human and animal health. It was only with the coming into existence of the Cartagena Protocol on Biosafety (Cartagena Protocol to the CBD in 2000 that the safe transfer, handling and use of living modified organisms (LMOs such as genetically engineered plants, animals, and microbes were at last being catered for, albeit leaving aside the broader categories of GMOs. Due to the need for the negotiators of this protocol to make compromises, there were still key issues on the international biosafety framework pertaining mainly to the scope of the GMOs to be covered by this protocol and by the Advanced Informed Agreement procedure; identification and traceability issues; and liability and redress issues. Nine years after the entry into force of the Cartagena Protocol the transboundary movements of GMOs have clearly increased with new categories of GMOs and genetically modified products to regulate.

HIV stigma plays a major role in the etiology of psychological distress among persons living with HIV, but may be ameliorated by social support. This cross-sectional study examined whether social support mediates or moderates the relationship between HIV stigma and psychological symptoms. We recruited a convenience sample of 210 individuals living with HIV in three peri-urban communities in the Western Cape, South Africa. People living with HIV and AIDS (PLWHA) completed self-report questionnaires that assessed HIV-related stigma, social support, post-traumatic stress disorder (PTSD) and depression. Product-term regression analyses showed that social support played a mediating role in the relationship between HIV-related stigma and symptoms of PTSD (not depression). Social support did not, however, moderate the relationship between HIV-related stigma and PTSD or depression. The results indicate that perceived HIV-related stigma may decrease PLWHA's perceived level of social support, which in turn may increase PTSD symptoms. Moreover, these findings suggest that despite the protective role of social support, there are other factors that affect the relationship between HIV-related stigma and mental health that hinder the buffering role of social support in this relationship. These findings may have implications for designing and implementing interventions that increase perceived social support and decrease perceived HIV-related stigma, which in turn may decrease symptoms of PTSD among PLWHA.

2016-05-09

The public discourse on the acceptability of genetically modified organisms (GMOs) is not only controversial, but also infused with highly emotional and moralizing rhetoric. Although the assessment of risks and benefits of GMOs must be a scientific exercise, many debates on this issue seem to remain impervious to scientific evidence. In many cases, the moral psychology attributes of the general public create incentives for both GMO opponents and proponents to pursue misleading public campaigns, which impede the comprehensive assessment of the full spectrum of the risks and benefits of GMOs. The ordonomic approach to economic ethics introduced in this research note is helpful for disentangling the socio-economic and moral components of the GMO debate by re- and deconstructing moral claims.

To investigate whether Pi (Spleen) qi-deficiency affected psychological and neural responses in relevance to cognitive control. Pi qi-deficient and balanced participants were asked to perform the Stroop task, a classical cognitive control paradigm. In this paradigm, participants had to judge the color of the prompted word. The word's meaning indicated the color (the consistent condition) or not (the inconsistent condition), or were unrelated to the color (the neutral condition). Electroencephalograph (EEG) was recorded during the task. Event-related potential (ERP) results showed that Pi qi-deficient individuals failed to exhibit a normal Stroop effect as Balanced individuals did, such as the accuracy differences between the consistent and the inconsistent conditions as well as the N450 effect (P>0.05). Meanwhile, Pi qi-deficient individuals displayed larger P2 and P3 amplitudes than balanced individuals did during performing the cognitive control task (Pcognitive control aspect.

With the growing number of GMOs introduced to the market, testing laboratories have seen their workload increase significantly. Ready-to-use multi-target PCR-based detection systems, such as pre-spotted plates (PSP), reduce analysis time while increasing capacity. This paper describes the development and applicability to GMO testing of a screening strategy involving a PSP and its associated web-based Decision Support System. The screening PSP was developed to detect all GMOs authorized in the EU in one single PCR experiment, through the combination of 16 validated assays. The screening strategy was successfully challenged in a wide inter-laboratory study on real-life food/feed samples. The positive outcome of this study could result in the adoption of a PSP screening strategy across the EU; a step that would increase harmonization and quality of GMO testing in the EU. Furthermore, this system could represent a model for other official control areas where high-throughput DNA-based detection systems are needed. Copyright © 2016 The Authors.

The images and spectra that are the basis of this study were recorded with Gemini Multi-Object Spectrograph (GMOS) on Gemini South as part of program GS-2014A-Q-84 (PI: Davidge). GMOS is the facility visible-light imager and spectrograph. The detector was (the CCDs that make up the GMOS detector have since been replaced) a mosaic of three 2048*4068 EEV CCDs. Each 13.5μm square pixel subtended 0.073arcsec on the sky. The three CCDs covered an area that is larger than that illuminated by the sky so that spectra could be dispersed outside of the sky field. The images and spectra were both recorded with 2*2 pixel binning. The g' (FWHM=0.55) and i' (FWHM=0.45) images of Haffner 16 were recorded on the night of 2013 December 31. The GMOS spectra were recorded during five nights in 2014 March (Mar 19, Mar 27, and Mar 30) and April (Apr 2, and Apr 3). The spectra were dispersed with the R400 grating (λblaze=7640Å, 400lines/mm). (1 data file).

Testing connections between exo-atmospheres and their host stars. GEMINI-N/GMOS ground-based transmission spectrum of Qatar-1b

Till date, only a handful exo-atmospheres have been well characterized, mostly by means of the transit method. Some classic examples are HD 209458b, HD 189733b, GJ-436b, and GJ-1214b. Data show exoplanet atmospheres to be diverse. However, this is based on a small number of cases. Here we focus our study on the exo-atmosphere of Qatar-1b, an exoplanet that looks much like HD 189733b regarding its host star's activity level, their surface gravity, scale height, equilibrium temperature and transit parameters. Thus, our motivation relied on carrying out a comparative study of their atmospheres, and assess if these are regulated by their environment. In this work we present one primary transit of Qatar-1b obtained during September, 2014, using the 8.1 m GEMINI North telescope. The observations were performed using the GMOS-N instrument in multi-object spectroscopic mode. We collected fluxes of Qatar-1 and six more reference stars, covering the wavelength range between 460 and 746 nm. The achieved photometric precision of 0.18 parts-per-thousand in the white light curve, at a cadence of 165 s, makes this one of the most precise datasets obtained from the ground. We created 12 chromatic transit light curves that we computed by integrating fluxes in wavelength bins of different sizes, ranging between 3.5 and 20 nm. Although the data are of excellent quality, the wavelength coverage and the precision of the transmission spectrum are not sufficient to neither rule out or to favor classic atmospheric models. Nonetheless, simple statistical analysis favors the clear atmosphere scenario. A larger wavelength coverage or space-based data is required to characterize the constituents of Qatar-1b's atmosphere and to compare it to the well known HD 189733b. On top of the similarities of the orbital and physical parameters of both exoplanets, from a long Hα photometric follow-up of Qatar-1, presented in this work, we find Qatar-1 to be as active as HD 189733.

The Hippocratic need for adequate supports while merging programs: at first do no harm

Science.gov (United States)

Sipple, John W.

2017-03-01

In response to a paper calling for the re-engagement of agricultural education with the sciences and science education, this essay is supportive but argues to proceed with caution: one that at first does no harm. I offer a supplementary lens and story of change at Cornell University as a cautionary and motivational tale. I concur with the authors who want to redirect faculty, departments, and societies of agricultural educators to become more tightly aligned with the sciences. The need for and ability to better contribute to the critical discussions on contemporary agriculture issues (e.g., urban farming, GMOs, sustainability, local economies) is timely and important. The trick, however, is to do this without weakening the agricultural education community to the point of extinction. Drawing on Institutional Theory, I offer an enhanced perspective highlighting the importance of resource, conformity, and legitimacy. I explore the nature of competing pressures: the strong and restrictive ties to isolated communities and the pressure to reengage a community with a more socially and intellectually central world. I want to emphasize how these strong ties are typically beneficial to the organizations of interest, despite what it may look like to others outside that sector. It is argued that agricultural education will become increasingly "vulnerable and isolated" should it not cross the street and at least partially connect with contemporary science, social science, and new policy and ethical concerns.

New trends in bioanalytical tools for the detection of genetically modified organisms: an update.

Despite the controversies surrounding genetically modified organisms (GMOs), the production of GM crops is increasing, especially in developing countries. Thanks to new technologies involving genetic engineering and unprecedented access to genomic resources, the next decade will certainly see exponential growth in GMO production. Indeed, EU regulations based on the precautionary principle require any food containing more than 0.9% GM content to be labeled as such. The implementation of these regulations necessitates sampling protocols, the availability of certified reference materials and analytical methodologies that allow the accurate determination of the content of GMOs. In order to qualify for the validation process, a method should fulfil some criteria, defined as "acceptance criteria" by the European Network of GMO Laboratories (ENGL). Several methods have recently been developed for GMO detection and quantitation, mostly based on polymerase chain reaction (PCR) technology. PCR (including its different formats, e.g., double competitive PCR and real-time PCR) remains the technique of choice, thanks to its ability to detect even small amounts of transgenes in raw materials and processed foods. Other approaches relying on DNA detection are based on quartz crystal microbalance piezoelectric biosensors, dry reagent dipstick-type sensors and surface plasmon resonance sensors. The application of visible/near-infrared (vis/NIR) spectroscopy or mass spectrometry combined with chemometrics techniques has also been envisaged as a powerful GMO detection tool. Furthermore, in order to cope with the multiplicity of GMOs released onto the market, the new challenge is the development of routine detection systems for the simultaneous detection of numerous GMOs, including unknown GMOs.

To examine support for local policies encouraging physical activity and perceived neighborhood environment characteristics by physical activity and weight status of respondents across U.S. counties. We used a random-digit-dial, computer-assisted telephone interview (CATI) to conduct a cross-sectional telephone questionnaire in selected U.S. counties in 2011. Counties with high prevalences of obesity and sedentary behavior (HH; n = 884) and counties with low prevalences of obesity and sedentary behavior (LL; n = 171) were selected nationally. Adult respondents from HH (n = 642) and LL (n = 566) counties. Questions were asked of respondents, pertaining to support for physical activity policies in various settings, neighborhood features, time spent in physical activity and sedentary behaviors, self-reported weight and height, and personal demographic information. Means and frequencies were calculated; bivariable and multivariable linear and logistic regression models, developed. Models were adjusted for individual characteristics and county HH/LL status. Respondents in LL counties perceived their neighborhood and work environments to be more supportive of healthy behaviors and were more supportive of local physical activity policies than respondents in HH counties (p physical activity, and decreased sedentary behavior. Policy support and neighborhood environments are associated with behaviors. Results can inform targeting policy agendas to facilitate the improvement of environments (community, work, and school) to be more supportive of physical activity.

Advances in understanding the control mechanisms governing the behavior of cells in adherent mammalian tissue culture models are becoming increasingly dependent on modes of single-cell analysis. Methods which deliver composite data reflecting the mean values of biomarkers from cell populations risk losing subpopulation dynamics that reflect the heterogeneity of the studied biological system. In keeping with this, traditional approaches are being replaced by, or supported with, more sophisticated forms of cellular assay developed to allow assessment by high-content microscopy. These assays potentially generate large numbers of images of fluorescent biomarkers, which enabled by accompanying proprietary software packages, allows for multi-parametric measurements per cell. However, the relatively high capital costs and overspecialization of many of these devices have prevented their accessibility to many investigators. Described here is a universally applicable workflow for the quantification of multiple fluorescent marker intensities from specific subcellular regions of individual cells suitable for use with images from most fluorescent microscopes. Key to this workflow is the implementation of the freely available Cell Profiler software(1) to distinguish individual cells in these images, segment them into defined subcellular regions and deliver fluorescence marker intensity values specific to these regions. The extraction of individual cell intensity values from image data is the central purpose of this workflow and will be illustrated with the analysis of control data from a siRNA screen for G1 checkpoint regulators in adherent human cells. However, the workflow presented here can be applied to analysis of data from other means of cell perturbation (e.g., compound screens) and other forms of fluorescence based cellular markers and thus should be useful for a wide range of laboratories.

High-stress individuals may benefit from social support, although their support providers may be adversely affected via stress crossover effects. Individual and crossover effects of perceived stress within medical student marriages (n = 30) were investigated. Perceived spousal support was positively associated with individuals' own marital and emotional adjustment, attenuating stress effects. With regard to crossover effects, medical students' perceived stress was significantly associated with their spouses' emotional adjustment. Further, medical students' own emotional adjustment fully mediated this crossover effect. Results suggest that the contagion of negative affect may serve as a key mechanism through which stress crossover effects operate in marriage.

Social Withdrawal Among Individuals Receiving Psychiatric Care: Derivation of a Scale Using Routine Clinical Assessment Data to Support Screening and Outcome Measurement.

Social withdrawal is a symptom experienced by individuals with an array of mental health conditions, particularly those with schizophrenia and mood disorders. Assessments of social withdrawal are often lengthy and may not be routinely integrated within the comprehensive clinical assessment of the individual. This study utilized item response and classical test theory methods to derive a Social Withdrawal Scale (SWS) using items embedded within a routine clinical assessment, the RAI-Mental Health (RAI-MH). Using data from 60,571 inpatients in Ontario, Canada, a common factor analysis identified seven items from the RAI-MH that measure social withdrawal. A graded response model found that six items had acceptable discrimination parameters: lack of motivation, reduced interaction, decreased energy, flat affect, anhedonia, and loss of interest. Summing these items, the SWS was found to have strong internal consistency (Cronbach's alpha = 0.82) and showed a medium to large effect size (d = 0.77) from admission to discharge. Fewer individuals with high SWS scores participated in social activity or reported having a confidant compared to those with lower scores. Since the RAI-MH is available across clinical subgroups in several jurisdictions, the SWS is a useful tool for screening, clinical decision support, and evaluation.

We selected four intermediate-luminosity ETGs from the ACS Virgo Cluster Survey (ACSVCS; Cote et al. 2004, J/ApJS/153/223), a homogeneous Hubble Space Telescope survey of 100 ETGs in the nearby Virgo cluster of galaxies using the Advanced Camera for Surveys (ACS; Ford et al. 1998SPIE.3356..234F). We observed these galaxies with the Gemini Multi-Object Spectrographs (GMOS, Hook et al. 2004PASP..116..425H), twin instruments on the Gemini North and Gemini South telescopes. Our target galaxies have sizes (Re~10-18") that fit well within the GMOS field of view (5.5 arcmin2), providing coverage out to 10-16Re. Each galaxy contained ~50 targetable GCs with VGMOS-South, whereas data for VCC 685 was taken with GMOS-North. (3 data files).

HIV/AIDS, a chronic burden in Ghana, poses social and health outcome concerns to those infected. Examining the Medical Outcome Study Social Support Survey (MOS-SSS) instrument among 300 Ghanaians from a cross-sectional design, Principal Component Analysis yielded four factors (positive interaction, trust building, information giving, and essential support), which accounted for 85.73% of the total variance in the MOS-SSS. A logistic regression analysis showed that essential support was the strongest predictor of the length of time an individual stayed in the support group, whereas positive interaction indicated negative association. The study's implications for policy, research, and practice were discussed.

To investigate the impact of rehabilitation measures on work ability and return to work (RTW), specifically the association between workplace rehabilitation/supportive conditions at work and work ability and RTW over time, among women on long-term sick leave. Questionnaire data were collected (baseline, 6 and 12 months) from a cohort of women (n = 324). Linear mixed models were used for longitudinal analysis of the repeated measurements of work ability index (WAI), work ability score and working degree. These analyses were performed with different models; the explanatory variables for each model were workplace rehabilitation, supportive conditions at work and time. The individuals provided with workplace rehabilitation and supportive conditions (e.g. influence at work, possibilities for development, degree of freedom at work, meaning of work, quality of leadership, social support, sense of community and work satisfaction) had significantly increased WAI and work ability score over time. These individuals scored higher work ability compared to those individuals having workplace rehabilitation without supportive conditions, or neither. Additionally, among the individuals provided with workplace rehabilitation and supportive conditions, working degree increased significantly more over time compared to those individuals with no workplace rehabilitation and no supportive conditions. The results highlight the importance of integrating workplace rehabilitation with supportive conditions at work in order to increase work ability and improve the RTW process for women on long-term sick leave.

A key aspect of the optimal support of students with special needs is co-ordination and co-operation between school, home and specialized agencies. Communication between these entities is of prime importance and can be facilitated through the use of a support system implementing ICF guidelines as outlined. This communication system can be considered to be a preventative rather than allopathic support.

Spirituality and religion among HIV-infected individuals.

Szaflarski, Magdalena

2013-12-01

Spirituality and religion are important to many people living with HIV (PLWH). Recent research has focused on special populations (ethnic-minorities, women, and youth), spirituality/religion measurement, mediating/moderating mechanisms, and individual and community-level interventions. Spirituality/religion in PLWH has been refined as a multidimensional phenomenon, which improves health/quality of life directly and through mediating factors (healthy behaviors, optimism, social support). Spirituality/religion helps people to cope with stressors, especially stigma/discrimination. Spiritual interventions utilizing the power of prayer and meditation and addressing spiritual struggle are under way. Faith-based community interventions have focused on stigma and could improve individual outcomes through access to spiritual/social support and care/treatment for PLWA. Community engagement is necessary to design/implement effective and sustainable programs. Future efforts should focus on vulnerable populations; utilize state-of-the-art methods (randomized clinical trials, community-based participatory research); and, address population-specific interventions at individual and community levels. Clinical and policy implications across geographic settings also need attention.

Deficits in metacognition, or the ability to form complex ideas about self and others, may be a root cause of dysfunction in schizophrenia. Accordingly, forms of psychotherapy have been proposed to address metacognitive deficits. This study explored whether metacognitively focused individual psychotherapy can affect self-experience by conducting narrative interviews of patients with a schizophrenia spectrum disorder enrolled in either metacognitively oriented psychotherapy (n = 12) or supportive psychotherapy (n = 13) in a naturalistic setting. Participants in both groups completed a narrative interview consisting of questions that focused on perceptions and process of psychotherapy and its impact on outcomes. Interviews were audiotaped, transcribed, and coded using an inductive process informed by grounded theory. Qualitative analyses revealed all participants reported psychotherapy led to improvements in self-esteem and the ability to think more clearly and set meaningful goals. The group receiving metacognitively oriented therapy, in contrast to those receiving supportive therapy, reported being able to integrate their current experiences into the larger narratives of their lives and an increased experience of sense of agency and the ability to understand and manage pain. Results provide evidence that metacognitively oriented psychotherapy may promote subjective forms of recovery.

Providers and Patients Caught Between Standardization and Individualization: Individualized Standardization as a Solution

Science.gov (United States)

Ansmann, Lena; Pfaff, Holger

2018-01-01

In their 2017 article, Mannion and Exworthy provide a thoughtful and theory-based analysis of two parallel trends in modern healthcare systems and their competing and conflicting logics: standardization and customization. This commentary further discusses the challenge of treatment decision-making in times of evidence-based medicine (EBM), shared decision-making and personalized medicine. From the perspective of systems theory, we propose the concept of individualized standardization as a solution to the problem. According to this concept, standardization is conceptualized as a guiding framework leaving room for individualization in the patient physician interaction. The theoretical background is the concept of context management according to systems theory. Moreover, the comment suggests multidisciplinary teams as a possible solution for the integration of standardization and individualization, using the example of multidisciplinary tumor conferences and highlighting its limitations. The comment also supports the authors’ statement of the patient as co-producer and introduces the idea that the competing logics of standardization and individualization are a matter of perspective on macro, meso and micro levels.

Complexity in Individual Trajectories toward Online Extremism

2018-01-01

Full Text Available Society faces a fundamental global problem of understanding which individuals are currently developing strong support for some extremist entity such as ISIS (Islamic State, even if they never end up doing anything in the real world. The importance of online connectivity in developing intent has been confirmed by recent case studies of already convicted terrorists. Here we use ideas from Complexity to identify dynamical patterns in the online trajectories that individuals take toward developing a high level of extremist support, specifically, for ISIS. Strong memory effects emerge among individuals whose transition is fastest and hence may become “out of the blue” threats in the real world. A generalization of diagrammatic expansion theory helps quantify these characteristics, including the impact of changes in geographical location, and can facilitate prediction of future risks. By quantifying the trajectories that individuals follow on their journey toward expressing high levels of pro-ISIS support—irrespective of whether they then carry out a real-world attack or not—our findings can help move safety debates beyond reliance on static watch-list identifiers such as ethnic background or immigration status and/or postfact interviews with already convicted individuals. Given the broad commonality of social media platforms, our results likely apply quite generally; for example, even on Telegram where (like Twitter there is no built-in group feature as in our study, individuals tend to collectively build and pass through the so-called super-group accounts.

Full Text Available Work is important for one’s self-esteem, social standing and ability to participate in the community as well as for the material advantages it brings to individuals and their families. The evidence suggests that the benefits of employment outweigh the risks of work and are greater than the risks of long-term unemployment or sickness absence. Individuals may be born with physical or intellectual disadvantages (e.g., cerebral palsy, or they may be acquired during childhood or adult life. Some progressive conditions may present in childhood or adolescence (e.g., some muscular dystrophies and these need to be distinguished from those presenting later in life (e.g., trauma, stroke. Vocational rehabilitation (VR thus takes three forms: preparing those with a disability, health or mental health condition for the world of work, job retention for those in work and assisting those out of work into new work. Important components of VR consist of the attributes of the individual, the skills/knowledge of their health professionals, the knowledge and attitudes of actual or potential employers and the assistance that is provided by the state or other insurance facility. Charities are playing an increasing role.

Reciprocity of agonistic support in ravens.

Cooperative behaviour through reciprocation or interchange of valuable services in primates has received considerable attention, especially regarding the timeframe of reciprocation and its ensuing cognitive implications. Much less, however, is known about reciprocity in other animals, particularly birds. We investigated patterns of agonistic support (defined as a third party intervening in an ongoing conflict to attack one of the conflict participants, thus supporting the other) in a group of 13 captive ravens, Corvus corax. We found support for long-term, but not short-term, reciprocation of agonistic support. Ravens were more likely to support individuals who preened them, kin and dominant group members. These results suggest that ravens do not reciprocate on a calculated tit-for-tat basis, but aid individuals from whom reciprocated support would be most useful and those with whom they share a good relationship. Additionally, dyadic levels of agonistic support and consolation (postconflict affiliation from a bystander to the victim) correlated strongly with each other, but we found no evidence to suggest that receiving agonistic support influences the victim's likelihood of receiving support (consolation) after the conflict ends. Our findings are consistent with an emotionally mediated form of reciprocity in ravens and provide additional support for convergent cognitive evolution in birds and mammals.

Application of Polymerase Chain Reaction for High Sensitivity Detection of Roundup Ready™ Soybean Seeds and Grains in Varietal Mixtures

Directory of Open Access Journals (Sweden)

Ashok Pandey

2011-01-01

Full Text Available Strong increase in the production of genetically modified organisms (GMOs observed over the years has led to a consolidation of transgenic seed industries worldwide. The dichotomy between the evaluated risk and the perceived risk of transgenic use has defined their level of acceptability among different global societies. GMOs have been widely applied to agricultural commodities, among them the Roundup Ready™ (RR™ soybean line GTS 40-3-2 has become the most prevalent transgenic crop in the world. This variety was developed to confer plant tolerance against glyphosate-based agricultural herbicide Roundup Ready™. Issues related to detection and traceability of GMOs have gained worldwide interest due to their increasing global diffusion and the related socioeconomic and health implications. Also, due to the widespread use of GMOs in food production, labelling regulations have been established in some countries to protect the right of consumers and producers. Besides regulatory demand, consumer concern issues have resulted in the development of several methods of detecting and quantifying foods derived from genetically engineered crops and their raw materials. Polymerase chain reaction (PCR has been proven to be the method of choice to detect the presence or absence of the introduced genes of GMOs at DNA level. The present paper aims to verify whether the PCR technique can detect RR™ soybean seeds among conventional ones to further certification as non-GM soybean seeds and grains. This analysis could be accomplished through the development of new methodology called 'intentional contamination' of soybean conventional seeds or grains with the respective RR™ soybeans. The results show that the PCR method can be applied with high sensitivity in order to certify conventional soybean seeds and grains.

Quantification of genetically modified organisms (GMOs) in food and feed products is often required for their labelling or for tolerance thresholds. Standard-curve-based simplex quantitative polymerase chain reaction (qPCR) is the prevailing technology, which is often combined with screening analysis. With the rapidly growing number of GMOs on the world market, qPCR analysis becomes laborious and expensive. Innovative cost-effective approaches are therefore urgently needed. Here, we report the development and inter-laboratory assessment of multiplex assays to quantify GMO soybean using droplet digital PCR (ddPCR). The assays were developed to facilitate testing of foods and feed for compliance with current GMO regulations in the European Union (EU). Within the EU, the threshold for labelling is 0.9% for authorised GMOs per ingredient. Furthermore, the EU has set a technical zero tolerance limit of 0.1% for certain unauthorised GMOs. The novel multiplex ddPCR assays developed target 11 GMO soybean lines that are currently authorised, and four that are tolerated, pending authorisation in the EU. Potential significant improvements in cost efficiency are demonstrated. Performance was assessed for the critical parameters, including limits of detection and quantification, and trueness, repeatability, and robustness. Inter-laboratory performance was also determined on a number of proficiency programme and real-life samples.

Since more than one hundred events of genetically modified organisms (GMOs) have been developed and approved for commercialization in global area, the GMO analysis methods are essential for the enforcement of GMO labelling regulations. Protein and nucleic acid-based detection techniques have been developed and utilized for GMOs identification and quantification. However, the information for harmonization and standardization of GMO analysis methods at global level is needed. GMO Detection method Database (GMDD) has collected almost all the previous developed and reported GMOs detection methods, which have been grouped by different strategies (screen-, gene-, construct-, and event-specific), and also provide a user-friendly search service of the detection methods by GMO event name, exogenous gene, or protein information, etc. In this database, users can obtain the sequences of exogenous integration, which will facilitate PCR primers and probes design. Also the information on endogenous genes, certified reference materials, reference molecules, and the validation status of developed methods is included in this database. Furthermore, registered users can also submit new detection methods and sequences to this database, and the newly submitted information will be released soon after being checked. GMDD contains comprehensive information of GMO detection methods. The database will make the GMOs analysis much easier.

Cultivation and marketing of genetically modified organisms (GMOs) have been unevenly adopted worldwide. To facilitate international trade and to provide information to consumers, labelling requirements have been set up in many countries. Quantitative real-time polymerase chain reaction (qPCR) is currently the method of choice for detection, identification and quantification of GMOs. This has been critically assessed and the requirements for the method performance have been set. Nevertheless, there are challenges that should still be highlighted, such as measuring the quantity and quality of DNA, and determining the qPCR efficiency, possible sequence mismatches, characteristics of taxon-specific genes and appropriate units of measurement, as these remain potential sources of measurement uncertainty. To overcome these problems and to cope with the continuous increase in the number and variety of GMOs, new approaches are needed. Statistical strategies of quantification have already been proposed and expanded with the development of digital PCR. The first attempts have been made to use new generation sequencing also for quantitative purposes, although accurate quantification of the contents of GMOs using this technology is still a challenge for the future, and especially for mixed samples. New approaches are needed also for the quantification of stacks, and for potential quantification of organisms produced by new plant breeding techniques.

Since the introduction of genetically modified organisms (GMOs), there has been on-going and continuous concern and debates on the commercialization of products derived from GMOs. There is an urgent need for development of highly efficient analytical methods for rapid and high throughput screening of GMOs components, as required for appropriate labeling of GMO-derived foods, as well as for on-site inspection and import/export quarantine. In this study, we describe, for the first time, a multi-labeling based electrochemical biosensor for simultaneous detection of multiple DNA components of GMO products on the same sensing interface. Two-round signal amplification was applied by using both an exonuclease enzyme catalytic reaction and gold nanoparticle-based bio-barcode related strategies, respectively. Simultaneous multiple detections of different DNA components of GMOs were successfully achieved with satisfied sensitivity using this electrochemical biosensor. Furthermore, the robustness and effectiveness of the proposed approach was successfully demonstrated by application to various GMO products, including locally obtained and confirmed commercial GMO seeds and transgenetic plants. The proposed electrochemical biosensor demonstrated unique merits that promise to gain more interest in its use for rapid and on-site simultaneous multiple screening of different components of GMO products.

Detection of nonauthorized genetically modified organisms (GMOs) has always presented an analytical challenge because the complete sequence data needed to detect them are generally unavailable although sequence similarity to known GMOs can be expected. A new approach, differential quantitative polymerase chain reaction (PCR), for detection of nonauthorized GMOs is presented here. This method is based on the presence of several common elements (e.g., promoter, genes of interest) in different GMOs. A statistical model was developed to study the difference between the number of molecules of such a common sequence and the number of molecules identifying the approved GMO (as determined by border-fragment-based PCR) and the donor organism of the common sequence. When this difference differs statistically from zero, the presence of a nonauthorized GMO can be inferred. The interest and scope of such an approach were tested on a case study of different proportions of genetically modified maize events, with the P35S promoter as the Cauliflower Mosaic Virus common sequence. The presence of a nonauthorized GMO was successfully detected in the mixtures analyzed and in the presence of (donor organism of P35S promoter). This method could be easily transposed to other common GMO sequences and other species and is applicable to other detection areas such as microbiology.

While perceived social support has received considerable research as a protective factor for suicide ideation, little attention has been given to the mechanisms that mediate its effects. We integrated two theoretical models, Joiner's (2005) interpersonal theory of suicide and Leary's (Leary, Tambor, Terdal, & Downs, 1995) sociometer theory of self-esteem to investigate two hypothesized mechanisms, utilization of social support and self-esteem. Specifically, we hypothesized that individuals must utilize the social support they perceive that would result in increased self-esteem, which in turn buffers them from suicide ideation. Participants were 172 college students who completed measures of social support, self-esteem, and suicide ideation. Tests of simple mediation indicate that utilization of social support and self-esteem may each individually help to mediate the perceived social support/suicide ideation relationship. Additionally, a test of multiple mediators using bootstrapping supported the hypothesized multiple-mediator model. The use of a cross-sectional design limited our ability to find true cause-and-effect relationships. Results suggested that utilized social support and self-esteem both operate as individual moderators in the social support/self-esteem relationship. Results further suggested, in a comprehensive model, that perceived social support buffers suicide ideation through utilization of social support and increases in self-esteem.

The department for the measurements of individual doses makes regular dose controls by means of film badges for approximately 14000 individuals. The operation is facilitated by a Honeywell Bull Mini 6 Mod 43 computer. The computer language is COBOL applied to registering of in-data such as delivery of badges, film development, calibration, invoices, recording of individual doses and customers. The print-out consists of customers, badge codes, dosimeter lists, development specifications, dose statements, addresses, bills, dose statistics and the register of individuals. As a consequence of charges the activity is financially self-supporting. (G.B.)

Little research has examined the characteristics of peer support. Pertinent to such examination may be characteristics such as the distinction between nondirective support (accepting recipients' feelings and cooperative with their plans) and directive (prescribing "correct" choices and feelings). In a peer support program for individuals with diabetes, this study examined (a) whether the distinction between nondirective and directive support was reflected in participants' ratings of support provided by peer supporters and (b) how nondirective and directive support were related to depressive symptoms, diabetes distress, and Hemoglobin A1c (HbA1c). Three hundred fourteen participants with type 2 diabetes provided data on depressive symptoms, diabetes distress, and HbA1c before and after a diabetes management intervention delivered by peer supporters. At post-intervention, participants reported how the support provided by peer supporters was nondirective or directive. Confirmatory factor analysis (CFA), correlation analyses, and structural equation modeling examined the relationships among reports of nondirective and directive support, depressive symptoms, diabetes distress, and measured HbA1c. CFA confirmed the factor structure distinguishing between nondirective and directive support in participants' reports of support delivered by peer supporters. Controlling for demographic factors, baseline clinical values, and site, structural equation models indicated that at post-intervention, participants' reports of nondirective support were significantly associated with lower, while reports of directive support were significantly associated with greater depressive symptoms, altogether (with control variables) accounting for 51% of the variance in depressive symptoms. Peer supporters' nondirective support was associated with lower, but directive support was associated with greater depressive symptoms.

current theoretical references. Each informant brought an average of 10.37 individuals into the network. Among the 3 types of social support, there was a predominance of informational support given by health professionals. The importance of reciprocity in providing/receiving social support was also noted, as well as the participation of health professionals and the family functioning as social support. The conclusion reached was that the network of the elderly with pneumopathies is not cohesive, being restricted to the personal network of each individual, and that even so, the informants recognize and are satisfied with the social support it provides.

The objectives of this study were to investigate the effects of knee brace (KB) and kinesiotaping (KT) on functional performance and self-reported function in individuals six months post-ACLR who desired to return to their pre-injury activity levels but felt unable to do so due to kinesiophobia. This was a cross-sectional study involving 30 individuals six months post-ACLR with Tampa Kinesiophobia Scores >37. Individuals were tested under three conditions: no intervention, KB and KT in a randomized order. Isokinetic concentric quadriceps and hamstring strength tests, one leg hop test, star excursion balance test and global rating scale were assessed under the three conditions. The involved side showed that KT and KB significantly increased the hop distance (P=0.01, P=0.04) and improved balance (P=0.01, P=0.04), respectively, but only KB was found to increase the quadriceps and hamstring peak torques compared to no intervention (P<0.05). Individuals reported having better knee function with KB when compared to no intervention (P<0.001) and KT (P=0.03). Both KB and KT have positive effects in individuals post-ACLR which may assist in reducing kinesiophobia when returning to their pre-injury activity levels, with the KB appearing to offer the participants better knee function compared to KT.

2015-06-01

Being engaged in daily activities is a strong indicator of quality of life for individuals with intellectual disability (ID) who live in small community group homes. This study aimed to identify individual and organisational factors that predict high levels of engagement. Individuals with ID (n = 78), direct support professionals (DSPs; n = 174) and supervisors (n = 21) from 21 US group homes participated in the study. For each individual with ID, we conducted 80 min of observation at the person's residence. Information was also gathered regarding demographic characteristics, DSP competence, supervisor years of experience and management practices. Data were analysed using multilevel modelling. On average, individuals were engaged in social activities 12% of observed time and non-social activities 35% of the time. Individuals with greater adaptive skills who were supported by more competent staff showed significantly higher levels of social engagement. Individuals with less severe deficits in adaptive behaviours and less challenging behaviour showed higher levels of non-social engagement. Although none of the factors related to group homes were significant, 24% of the variance in non-social engagement existed among group homes. These results suggested that engagement is a dynamic construct. The extent to which an individual with ID is engaged in daily life is a result of interplay between the individual's characteristics and the group home environment. Future research is needed to investigate the influence of variables specific to the group home on the engagement level of individuals with disabilities. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Data from 147 individuals with schizophrenia were used to examine whether actively paranoid and non-paranoid indiv...

Group affiliation in self-management: support or threat to identity?

Bossy, Dagmara; Knutsen, Ingrid Ruud; Rogers, Anne; Foss, Christina

2017-02-01

Self-management is considered important in chronic illness, and contemporary health policy recommends participation in support groups for individuals with chronic conditions. Although withdrawal from or non-participation in support groups is an important problem, there is limited knowledge about individuals' own motivation for participation in or withdrawal from self-management support groups. To investigate how individuals with type 2 diabetes perceive participation in group-based self-management support. This is a qualitative focus group study using a semi-structured interview guide. Sixteen participants diagnosed with type 2 diabetes were included in the study. Individuals with and without group affiliations were mixed in three focus groups to trigger discussions. In the analysis, reoccurring themes of engagement and discussions between participants were focused within a theoretical frame of institutional logic. The focus groups are seen as social spaces where participants construct identity. Both participation and non-participation in group-based self-management support are associated with dealing with the stigma of having type 2 diabetes. Negotiations contribute to constructing an illness dignity as a response to the logic of moral responsibility for the disease. Contemporary policy contributes to societal understandings of individuals with type 2 diabetes as morally inadequate. Our study shows that group-based self-management support may counteract blame and contribute in negotiations of identity for individuals with type 2 diabetes. This mechanism makes participation in groups beneficial for some but stigma inducing for others. © 2016 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

Peer Support for the Hardly Reached: A Systematic Review.

Science.gov (United States)

Sokol, Rebeccah; Fisher, Edwin

2016-07-01

Health disparities are aggravated when prevention and care initiatives fail to reach those they are intended to help. Groups can be classified as hardly reached according to a variety of circumstances that fall into 3 domains: individual (e.g., psychological factors), demographic (e.g., socioeconomic status), and cultural-environmental (e.g., social network). Several reports have indicated that peer support is an effective means of reaching hardly reached individuals. However, no review has explored peer support effectiveness in relation to the circumstances associated with being hardly reached or across diverse health problems. To conduct a systematic review assessing the reach and effectiveness of peer support among hardly reached individuals, as well as peer support strategies used. Three systematic searches conducted in PubMed identified studies that evaluated peer support programs among hardly reached individuals. In aggregate, the searches covered articles published from 2000 to 2015. Eligible interventions provided ongoing support for complex health behaviors, including prioritization of hardly reached populations, assistance in applying behavior change plans, and social-emotional support directed toward disease management or quality of life. Studies were excluded if they addressed temporally isolated behaviors, were limited to protocol group classes, included peer support as the dependent variable, did not include statistical tests of significance, or incorporated comparison conditions that provided appreciable social support. We abstracted data regarding the primary health topic, categorizations of hardly reached groups, program reach, outcomes, and strategies employed. We conducted a 2-sample t test to determine whether reported strategies were related to reach. Forty-seven studies met our inclusion criteria, and these studies represented each of the 3 domains of circumstances assessed (individual, demographic, and cultural-environmental). Interventions

Social support and employee well-being: the conditioning effect of perceived patterns of supportive exchange.

Nahum-Shani, Inbal; Bamberger, Peter A; Bacharach, Samuel B

2011-03-01

Seeking to explain divergent empirical findings regarding the direct effect of social support on well-being, the authors posit that the pattern of supportive exchange (i.e., reciprocal, under-, or over-reciprocating) determines the impact of receiving support on well-being. Findings generated on the basis of longitudinal data collected from a sample of older blue-collar workers support the authors' predictions, indicating that receiving emotional support is associated with enhanced well-being when the pattern of supportive exchange is perceived by an individual as being reciprocal (support received equals support given), with this association being weaker when the exchange of support is perceived as being under-reciprocating (support given exceeds support received). Moreover, receiving support was found to adversely affect well-being when the pattern of exchange was perceived as being over-reciprocating (support received exceeds support given). Theoretical and practical implications of these findings are discussed.

Does Controversial Science Call For Public Participation? The Case Of Gmo Skepticism

Directory of Open Access Journals (Sweden)

Andreas Christiansen

2017-12-01

Full Text Available Many instances of new and emerging science and technology are controversial. Although a number of people, including scientific experts, welcome these developments, a considerable skepticism exists among members of the public. The use of genetically modified organisms (GMOs is a case in point. In science policy and in science communication, it is widely assumed that such controversial science and technology require public participation in the policy-making process. We examine this view, which we call the Public Participation Paradigm, using the case of GMOs as an example. We suggest that a prominent reason behind the call for public participation is the belief that such participation is required for democratic legitimacy. We then show that the most prominent accounts of democratic legitimacy do not, in fact, entail that public participation is required in cases of controversial science in general, or in the case of GMOs in particular.

A comparative evaluation of the regulation of GM crops or products containing dsRNA and suggested improvements to risk assessments.

Changing the nature, kind and quantity of particular regulatory-RNA molecules through genetic engineering can create biosafety risks. While some genetically modified organisms (GMOs) are intended to produce new regulatory-RNA molecules, these may also arise in other GMOs not intended to express them. To characterise, assess and then mitigate the potential adverse effects arising from changes to RNA requires changing current approaches to food or environmental risk assessments of GMOs. We document risk assessment advice offered to government regulators in Australia, New Zealand and Brazil during official risk evaluations of GM plants for use as human food or for release into the environment (whether for field trials or commercial release), how the regulator considered those risks, and what that experience teaches us about the GMO risk assessment framework. We also suggest improvements to the process. Copyright © 2013 Elsevier Ltd. All rights reserved.

The Impact of Social Support and Attachment Style on Quality of Life and Readiness to Change in a Sample of Individuals Receiving Medication-Assisted Treatment for Opioid Dependence.

Cavaiola, Alan A; Fulmer, Barbara A; Stout, David

2015-01-01

A basic principle within the addictions treatment field is that social support is a vital ingredient in the recovery process. This study examines the nature of social support in a sample of opioid-dependent men and women who are currently being treated in a medication-assisted treatment program (methadone). This research examines the types of social support behaviors that the opioid-dependent individuals consider helpful and explores whether attachment style (i.e., secure, ambivalent, or anxious attachment) was a determining factor in whether social support was perceived as helpful. The dependent variables included readiness to change addictive behaviors and abstinence from other mood-altering drugs. Participants (N = 159) completed a demographic questionnaire, the Significant Others Scale, the Experiences in Close Relationships Scale, the Multidimensional Scale of Perceived Social Support Assessment, the Readiness to Change Scale, and an Attachment Style Questionnaire. The demographic questionnaire included subjective ratings of self-improvement. Social support predicted perceived improvement in all of the areas examined (e.g., health, family/social relationships) and abstinence; however, attachment style did not predict improvement or with readiness to change. Social support is an important factor in one's recovery from substance use disorders. Yet attachment style (i.e., anxious, avoidant, or secure) did not predict abstinence or overall improvement in functioning.

Health care proxies make important end-of-life decisions for individuals with dementia. A cross-sectional survey was conducted to examine the role of advance care planning in proxy decision making for 141 individuals with cognitive impairment, Alzheimer's disease, or other types of dementia. Proxies who did not know the preferences of individuals with dementia for life support treatments reported greater understanding of their values. Proxies of individuals with dementia who did not want life support treatments anticipated receiving less support and were more uncertain in decision making. The greater knowledge proxies had about dementia trajectory, family support, and trust of physicians, the more informed, clearer, and less uncertain they were in decision making. In addition to advance care planning, multiple factors influence proxy decision making, which should be considered in developing interventions and future research to support informed decision making for individuals with dementia and their families.

Antarctic skuas recognize individual humans.

2016-07-01

Recent findings report that wild animals can recognize individual humans. To explain how the animals distinguish humans, two hypotheses are proposed. The high cognitive abilities hypothesis implies that pre-existing high intelligence enabled animals to acquire such abilities. The pre-exposure to stimuli hypothesis suggests that frequent encounters with humans promote the acquisition of discriminatory abilities in these species. Here, we examine individual human recognition abilities in a wild Antarctic species, the brown skua (Stercorarius antarcticus), which lives away from typical human settlements and was only recently exposed to humans due to activities at Antarctic stations. We found that, as nest visits were repeated, the skua parents responded at further distances and were more likely to attack the nest intruder. Also, we demonstrated that seven out of seven breeding pairs of skuas selectively responded to a human nest intruder with aggression and ignored a neutral human who had not previously approached the nest. The results indicate that Antarctic skuas, a species that typically inhabited in human-free areas, are able to recognize individual humans who disturbed their nests. Our findings generally support the high cognitive abilities hypothesis, but this ability can be acquired during a relatively short period in the life of an individual as a result of interactions between individual birds and humans.

The purpose of this study was to investigate the moderating role of social support in the relationship between adaptability and life satisfaction. Data were collected from 99 undergraduate freshmen in a Chinese university using a lagged design with a 1-month interval. Results demonstrated that social support moderated the relation between adaptability and life satisfaction, such that the positive relation between adaptability and life satisfaction was stronger for individuals with higher levels of social support than for individuals with lower levels of social support. The theoretical and practical implications of this result are discussed.

2014-01-01

HIV is transmitted through dyadic exchanges of individuals linked in transitory or permanent networks of varying sizes. To optimize prevention efficacy, a complementary theoretical perspective that bridges key individual level elements with important network elements can be a foundation for developing and implementing HIV interventions with outcomes that are more sustainable over time and have greater dissemination potential. Toward that end, we introduce a Network-Individual-Resource (NIR) model for HIV prevention that recognizes how exchanges of resources between individuals and their networks underlies and sustains HIV-risk behaviors. Individual behavior change for HIV prevention, then, may be dependent on increasing the supportiveness of that individual's relevant networks for such change. Among other implications, an NIR model predicts that the success of prevention efforts depends on whether the prevention efforts (1) prompt behavior changes that can be sustained by the resources the individual or their networks possess; (2) meet individual and network needs and are consistent with the individual's current situation/developmental stage; (3) are trusted and valued; and (4) target high HIV-prevalence networks.

Full Text Available The need for functional risk assessment bodies in general, and in the biosafety field in particular, demands continued efforts and commitment from regulatory agencies, if results that are sustainable in time are to be achieved. The lack of formal processes that ensure continuity in the application of state of the art scientific criteria, the high rotation in some cases or the lack of experienced professionals, in others, is a challenge to be addressed. Capacity building initiatives with different approaches and degrees of success have been implemented in many countries over the years, supported by diverse governmental and non-governmental organizations. This document summarizes some capacity building experiences in developing countries and concludes that risk assessors taking ownership and regulatory authorities fully committed to developing and retaining highly qualified bodies are a sine qua non to achieve sustainable systems. To this end, it is essential to implement “in-house” continuing education mechanisms supported by external experts and organizations, and inter-institutional cooperation. It has to be noted that these recommendations could only be realized if policy makers understand and appreciate the value of professional, independent regulatory bodies.

Agricultural GMOs—What We Know and Where Scientists Disagree

David Zilberman

2018-05-01

Full Text Available Population growth, climate change, and increasing human impact on land and aquatic systems all pose significant challenges for current agricultural practices. Genetic engineering is a tool to speed up breeding for new varieties, which can help farmers and agricultural systems adapt to rapidly changing physical growing conditions, technology, and global markets. We review the current scientific literature and present the potential of genetically modified organisms (GMOs from the perspectives of various stakeholders. GMOs increase yields, lower costs, and reduce the land and environmental footprint of agriculture. The benefits of this technology are shared among innovators, farmers, and consumers. Developing countries and poor farmers gain substantially from GMOs. Agricultural biotechnology is diverse, with many applications having different potential impacts. Its regulation needs to balance benefits and risks for each application. Excessive precaution prevents significant benefits. Increasing access to the technology and avoidance of excessive regulation will allow it to reach its potential.

Individual and social determinants of obesity in strategic health messages: Interaction with political ideology.

Science.gov (United States)

Young, Rachel; Hinnant, Amanda; Leshner, Glenn

2016-07-01

Antiobesity health communication campaigns often target individual behavior, but these ads might inflate the role of individual responsibility at the expense of other health determinants. In a 2 × 2 full-factorial, randomized, online experiment, 162 American adults viewed antiobesity advertisements that varied in emphasizing social or individual causation for obesity through text and images. Locus for attribution of responsibility for obesity causes and solutions was measured, as was how these responses were moderated by political ideology. Participants who viewed text emphasizing individual responsibility were less likely to agree that genetic factors caused obesity. Conservative participants who viewed images of overweight individuals were less likely than liberal participants to agree that social factors were responsible for causing obesity. In addition, among conservative participants who viewed images of fast food versus images of overweight individuals, agreement that the food industry bore some responsibility mediated support for policy solutions to obesity. These findings, among others, demonstrate that awareness of multilevel determinants of health outcomes can be a precursor of support for policy solutions to obesity among those not politically inclined to support antiobesity policy. In addition, stigmatizing images of overweight individuals in antiobesity campaigns might overemphasize the role of individual behavior in obesity at the expense of other factors.

Male mating strategy and the introgression of a growth hormone transgene.

Valosaari, Kata-Riina; Aikio, Sami; Kaitala, Veijo

2008-11-01

Escaped transgenic organisms (GMO's) may threaten the populations of their wild relatives if able to hybridize with each other. The introgression of a growth enhancement transgene into a wild Atlantic salmon population may be affected by the transgene's effects not only on fitness parameters, but also on mating behaviour. Large anadromous GMO males are most preferred in mating, but a transgene can also give the large sneakers a reproductive advantage over the smaller wild individuals. With a simulation model, we studied whether the increase in the proportion and mating success of sneakers in transgenic and hybrid genotypes could facilitate the introgression of a transgene into wild population after the release of GMOs. The model combines population dynamics and Mendelian inheritance of a transgenic trait. We found that the introgression of the transgene is strongly affected by the greater mating preference of large GMO males. Furthermore, the difference in reproductive success between the anadromous versus sneaker strategy defines how much GMO's have to be preferred to be able to invade. These results emphasize the importance of detailed knowledge of reproductive systems and the effect of a transgene on the phenotype and behaviour of GMOs when assessing the consequences of their release or escape to the wild.

Supporting Multiple Cognitive Processing Styles Using Tailored Support Systems

International Nuclear Information System (INIS)

Tuan Q. Tran; Karen M. Feigh; Amy R. Pritchett

2007-01-01

According to theories of cognitive processing style or cognitive control mode, human performance is more effective when an individual's cognitive state (e.g., intuition/scramble vs. deliberate/strategic) matches his/her ecological constraints or context (e.g., utilize intuition to strive for a 'good-enough' response instead of deliberating for the 'best' response under high time pressure). Ill-mapping between cognitive state and ecological constraints are believed to lead to degraded task performance. Consequently, incorporating support systems which are designed to specifically address multiple cognitive and functional states e.g., high workload, stress, boredom, and initiate appropriate mitigation strategies (e.g., reduce information load) is essential to reduce plant risk. Utilizing the concept of Cognitive Control Models, this paper will discuss the importance of tailoring support systems to match an operator's cognitive state, and will further discuss the importance of these ecological constraints in selecting and implementing mitigation strategies for safe and effective system performance. An example from the nuclear power plant industry illustrating how a support system might be tailored to support different cognitive states is included

We explored the role that social support plays in the lives of women who have undergone bariatric surgery. We conducted in-depth interviews with 13 women who had had bariatric surgery (M age = 53.0 years) and analyzed the data using constant comparison processes. We found that individuals in participants' lives offered support by acting as role models and providing information, offering empathy and expressions of concern and caring, assisting with everyday responsibilities, and serving as companions. In turn, these forms of support guided participants' behavior, calmed their concerns, enhanced their self-esteem, relieved them of daily responsibilities, and offered them companionship in their bariatric journeys. Consistent with the existing theory, differently situated individuals specialized in offering particular types of support. Although participants appreciated the support received, many indicated a desire for more or "better" support, pointing to a need for resources guiding supporters in how to best offer support to bariatric patients. © The Author(s) 2015.

HIV is a major public health problem in the world, especially in sub-Saharan Africa. It often leads to loss of productive labour and disruption of existing social support system which results in deterioration of population health. This poses a great challenge to infected people in meeting their essential goods and services. This paper examines health and social support services provided by employers to HIV/AIDS infected employees in Tanzania. This was a cross-sectional study, which employed qualitative and quantitative methods in data collection and analysis. Structured questionnaires and in-depth interviews were used to assess the health and social support services provision at employers and employees perspectives. The study participants were employees and employers from public and private organizations. A total of 181 employees and 23 employers from 23 workplaces aged between 18-68 years were involved. The results show that 23.8% (i.e., 20.4% males and 27.3% females) of the employees had at least one member of the family or close relatives living with HIV at the time of the study. Fifty six percent of the infected employees reported to have been receiving health or social support from their employers. Employees' responses were consistent with those reported by their employers. A total of 12(52.2%) and 11(47.8%) employers reported to have been providing health and social supports respectively. Female employees (58.3%) from the private sector (60.0%) were more likely to receive supports than male employees (52.6%) and than those from the public sector (46.2%). The most common health and social support received by the employees were treatment, and nutritional support and reduction of workload, respectively. HIV/AIDS infected employees named treatment and nutritional support, and soft loans and reduced workload respectively, as the most important health and social supports they needed from their employers. This study provides baseline information for further studies

Risk analysis has become important to assess conditions and take decisions on control procedures. In this context it is considered a prerequisite in the evaluation of GM food. Many consumers worldwide worry that food derived from genetically modified organisms (GMOs) may be unhealthy and hence regulations on GMO authorisations and labelling have become more stringent. Nowadays there is a higher demand for non-GM products and these products could be differentiated from GM products using the identity preservation system (IP) that could apply throughout the grain processing system. IP is the creation of a transparent communication system that encompasses HACCP, traceability and related systems in the supply chain. This process guarantees that certain characteristics of the lots of food (non-GM origin) are maintained "from farm to fork". This article examines the steps taken by the Hellenic Food Safety Authority to examine the presence of GMOs in foods. The whole integrated European legislation framework currently in place still needs to be implemented in Greece. Penalties should be enforced to those who import, process GMOs without special licence and do not label those products. Similar penalties should be enforced to those companies that issue false certificates beyond the liabilities taken by the food enterprises for farmers' compensation. We argue that Greece has no serious reasons to choose the use of GMOs due to the fact that the structural and pedologic characteristics of the Greek agriculture favour the biological and integrated cultivation more. Greece is not in favour of the politics behind coexistence of conventional and GM plants and objects to the use of GMOs in the food and the environment because the processor has a big burden in terms of money, time and will suffer a great deal in order to prove that their products are GMO free or that any contamination is adventitious or technically unavoidable. Moreover, Greece owns a large variety of genetic

Stroke is an important causal factor of deficiency and functional dependence worldwide. To determine the immediate effects of visual and auditory biofeedback, combined with partial body weight supported (PBWS) treadmill training on the gait of individuals with chronic hemiparesis. Randomized controlled trial. Outpatient rehabilitation hospital. Thirty subjects with chronic hemiparesis and ability to walk with some help. Participants were randomized to a control group that underwent only PBWS treadmill training; or experimental I group with visual biofeedback from the display monitor, in the form of symbolic feet as the subject took a step; or experimental group II with auditory biofeedback associated display, using a metronome at 115% of the individual's preferred cadence. They trained for 20 minutes and were evaluated before and after training. Spatio-temporal and angular gait variables were obtained by kinematics from the Qualisys Motion Analysis system. Increases in speed and stride length were observed for all groups over time (speed: F=25.63; Phemiparesis, in short term. Additional studies are needed to determine whether, in long term, the biofeedback will promote additional benefit to the PBWS treadmill training. The findings of this study indicate that visual and auditory biofeedback does not bring immediate benefits on PBWS treadmill training of individuals with chronic hemiparesis. This suggest that, for additional benefits are achieved with biofeedback, effects should be investigated after long-term training, which may determine if some kind of biofeedback is superior to another to improve the hemiparetic gait.

Agricultural biotechnology--GMOs--has a huge positive impact on farming and farmers but remains controversial among the skeptical public. Curious but anxious consumers, driven by scare stories and pseudo-science provided by anti-GMO activists, seek accurate and authoritative answers to their questions. Here, I address a sample of such queries directed to me from the public, including the ubiquitous "Is it safe?" and also discuss some of the shameful tactics used by anti-GM activists in the public debate to garner support at the cost of inciting unnecessary anxiety among the public.

The methods applied in the brief data are based on DNA analysis by Polymerase Chain Reaction (PCR. This technique is specific, practical, reproducible and sensitive enough to detect up to 0.1% GMO in food and/or feedstuffs. Furthermore, all of the techniques mentioned are economic and can be applied in Syria and other developing countries. For all these reasons, the DNA-based analysis methods were chosen and preferred over protein-based analysis.

In contrast to previous research, we were interested not only in specific pain coping but also in more general stress coping strategies and their potential influence on pain outcomes. Analyses were performed using correlation and regression analyses. “Praying and hoping” turned out to be an independent predictor of higher pain intensity and higher anxiety levels, whereas both “coping self-instructions” and “diverting attention” were associated with higher well-being, less feelings of helplessness, and less depression and anxiety. We further found a link between “focusing on and venting emotions” and “worse pain adjustment”. No significant relationship between dyadic coping and social support with any of our pain outcomes could be observed. Overall, our results indicate that individual coping strategies outweigh the effects of social support and dyadic coping on pain-related outcomes and pain adjustment. However, results need to be interpreted with caution given the small sample size. Keywords: individual coping, dyadic coping, social support, chronic pain

The aim of the authors of the present study was to investigate gender differences in the levels of posttraumatic stress symptoms (PTSS) and social support in a Polish sample of HIV+ men (n = 613) and women (n = 230). This was an anonymous cross-sectional study, and participation was voluntary. The research questionnaires were distributed in paper form among patients of Warsaw's Hospital for Infectious Diseases from January to October 2015. The level of PTSS was assessed using the PTSD Factorial Version Inventory. Social support was assessed using the Berlin Social Support Scales. HIV+ women scored higher on all PTSS dimensions compared to HIV+ men. HIV+ women were characterized by a higher need for support and more support actually received compared to HIV+ men. We observed a positive association between HIV infection duration and AIDS phase and the global trauma score only among HIV+ men. The moderation analysis also revealed a positive relationship between actual received support and the global trauma score among HIV+ women only. Increased clinician awareness is needed about the role of PTSS and social support among people living with HIV, especially taking gender differences into account.

The purpose of this study was to investigate the moderating role of social support in the relationship between adaptability and life satisfaction. Data were collected from 99 undergraduate freshmen in a Chinese university using a lagged design with a 1-month interval. Results demonstrated that social support moderated the relation between adaptability and life satisfaction, such that the positive relation between adaptability and life satisfaction was stronger for individuals with higher levels of social support than for individuals with lower levels of social support. The theoretical and practical implications of this result are discussed. PMID:27516753

Paranoia is a common symptom of schizophrenia that may be related to how individuals process and respond to social stimuli. Previous investigations support a link between increased paranoia and greater social cognitive impairments, but these studies have been limited to single domains of social cognition, and no studies have examined how paranoia may influence functional outcome. Data from 147 individuals with schizophrenia were used to examine whether actively paranoid and non-paranoid individuals with schizophrenia differ in social cognition and functional outcomes. On measures assessing social cognitive bias, paranoid individuals endorsed more hostile and blaming attributions and identified more faces as untrustworthy; however, paranoid and non-paranoid individuals did not differ on emotion recognition and theory of mind tasks assessing social cognitive ability. Likewise, paranoid individuals showed greater impairments in real-world interpersonal relationships and social acceptability as compared to non-paranoid patients, but these differences did not extend to performance based tasks assessing functional capacity and social competence. These findings isolate specific social cognitive disparities between paranoid and non-paranoid subgroups and suggest that paranoia may exacerbate the social dysfunction that is commonly experienced by individuals with schizophrenia.

Body weight supported treadmill training (BWSTT) is a task-specific intervention that promotes functional locomotion. There is no research evaluating the effect of backward walking (BW) using BWSTT in individuals with spinal cord injury (SCI). The purpose of this single subject design was to examine the differences between forward walking (FW) and BW training using BWSTT in an individual with quadriparesis. The participant was a 57-year-old male with incomplete C3-C6 SCI. An ABABAB design (A = BW; B = FW; each phase = 3 weeks of biweekly sessions) was utilized. Outcome measures included: gait parameters; a timed 4-meter walk; the 5-repetition sit-to-stand test (STST); tandem stance time; and 6-minute walk test (6MWT). Data was analyzed with split level method of trend estimation. Improvements in gait parameters, on the timed 4-meter walk, 6MWT, tandem balance and aerobic endurance were similar with FW and BW training. The only difference between FW and BW training was that BW training resulted in greater improvements in the STST. The results of this study suggest that in this individual backward walking training was advantageous, resulting in improved ability to perform the 5-repetition STST. It is suspected that these changes can be attributed to the differences in muscle activation and task difficulty between FW and BW.

2016-01-01

Objectives This study examines whether belief in the food addiction construct is associated with support for obesity-related policies (e.g., restrictions on foods served in schools and workplace cafeterias, subsidies on fruits and vegetables), while simultaneously examining other factors associated with policy support (e.g., political party affiliation). Design Cross-sectional. Setting Online Community. Participants 200 individuals were recruited through Amazon Mechanical Turk. Measurements Participants (n = 193) responded to three questions about belief in food addiction and a measure evaluating support for 13 obesity-related policy initiatives. Individuals also completed the modified Yale Food Addiction Scale (mYFAS), self-reported height and weight, and provided demographic information (age, gender, race, political party affiliation). Results Belief in food addiction was significantly associated with greater support for obesity-related initiatives, even when accounting for the significant associations of age, gender, and political party. Belief in food addiction and political party both had moderate effect sizes for predicting support for obesity-related policy. There was an interaction between age and belief in food addiction, with significant associations with policy support for both younger and older individuals, though the effect was larger for younger participants. Conclusion The current study provides evidence that belief in food addiction is associated with increased obesity-related policy support, comparable to the influence of one’s political party. Growing evidence for the role of an addictive process in obesity may have important implications for public support of obesity-related policy initiatives. PMID:26808427

Many individuals with traumatic brain injury (TBI) are young and could have many years of productivity ahead of them. However, cognitive impairments may hinder individuals' ability to perform daily tasks. Assistive technology for cognition (ATC) can be effective in helping compensate for cognitive impairments. This study examined the current state of the research on using ATCs to support daily activities for individuals with cognitive disabilities that are due to TBI. A comprehensive systematic literature search was performed to identify peer-reviewed articles published between 2000 and 2015. To evaluate the nature of the research, qualitative data were extracted pertaining to recruitment, participant characteristics, intervention design, type of ATCs and their functions, matching individuals with ATCs, training for using the ATC, and outcomes. Research examining the effectiveness of ATCs as everyday compensatory tools for cognitive impairments that are due to TBI is limited. The majority of studies were case studies or quasi-experimental studies with small sample sizes. Studies showed positive associations between use of ATCs and individuals' abilities to perform tasks regardless of age, TBI severity, and time since injury. Future research should assess the match between the individual and the technology, study the impact of training on using ATCs, and analyze the usability of ATCs.

Full Text Available Genetic engineering has made possible the creation of Genetic Modified Organisms (GMOs, or transgenic crops. The growth around the world of transgenic crops areas for commercial purposes, such as soybean, maize, canola and cotton is being amazing: from 1.7 million hectares in 1996 to 52.6 million in 2001. Historically, not many technologies have reached, in such a short period of time, such a higher adoption. The use of these technologies, nevertheless their well-known benefits, has brought some worries related with biosafety. In Colombia the Colombian Institute for Agriculture and Cattle (ICA, its Spanish acronym in order to introduce GMOs to the country and prevent or minimize the potential risk for agriculture generated by this kind of organisms, has established two instruments: the Agreement 013/98, creating the National Technical Biosafety Committee (CTN, its Spanish acronym, intersectorial adviser organism; and the Resolution 3492/98, establishing procedures for introduction, production, reléase and marketing of GMOs for agricultural purposes. Under this regulations, ICA has approved five different requests involving eight events with GMOs: carnation for commercial multiplicación purposes; cotton and rice for evaluation genotype in field at a small scale; cassava, brachiaria, stylozantes, coffee and sugar cane for research in genetic improvement throughout genetic engineering techniques in confined handling. Based on the accomplished experience, the future will make improve the legal and institutional instruments, as well as technical and scientific capacity of the country in biosafety.

Although the study of delinquency has previously focused on identifying individual, family, peer, and social risk and protective factors, little empirical research has studied cultural factors and their relations to delinquency. In a large community sample of 329 Chinese, Cambodian, Laotian/Mien, and Vietnamese youths, individualism was positively related to, and collectivism negatively related to, self-reported delinquency, with partial mediation through peer delinquency (PD). Although the percentage of variance in delinquency attributable to individualism-collectivism was small compared to PD, it cannot be discounted as trivial. The results also supported the measurement and structural invariance of these associations across the 4 ethnic groups.

2017-06-01

Most people with profound intellectual and multiple disabilities (PIMD) have limited social contact and it is unclear what is done to maintain or increase these contacts. Individual support planning (ISP) can be used in the systematic enhancement of social contacts. This study analyses the content of ISPs with respect to the social contacts of people with PIMD. ISPs for 60 persons with PIMD in the Netherlands were inductively coded and illustrated with quotations. It turned out that every ISP contained information about social contacts. Of all the quotations extracted, 71.2% were about current conditions, 6.2% were about the future and less than 1% concerned actual goals. The social contacts of people with PIMD are mentioned in their ISPs, but this is rarely translated into goals. The results of the current study suggest that attention should be paid to ensuring that professionals understand the importance of social contacts and their application in practice.

She's supporting them; who's supporting her? Preschool center-level social-emotional supports and teacher well-being.

2016-12-01

Preschool teachers across the country have been charged to prepare children socially and emotionally for kindergarten. Teachers working in preschool centers are supporting children's social and emotional learning (SEL) within a rich ecology of emotion and social relationships and the present study considers how the supports implemented for children's SEL at the center-level are associated with teachers' psychological health and workplace experiences. Hierarchical linear models were constructed using data from the Head Start Family and Child Experiences Survey 2009 cohort. Results indicate that although teachers work in individual classrooms, they share common perceptions at the center-level of their workplace climate, access to support, and, although to a lesser extent, experience commonalities in psychological health and job satisfaction. Furthermore, in centers that had implemented more supports for children's SEL (including access to mental health consultants, classroom curriculum, and training and resources for teachers) teachers were less depressed, more satisfied with their jobs, felt more supported in managing challenging behavior, and viewed the workplace climate of their center as more positive. Findings are discussed in light of the national efforts to increase and retain a high-quality early childhood workforce. Copyright © 2016 Society for the Study of School Psychology.

This study evaluated the interactive association between individualism and drinking identity predicting alcohol use and problems. Seven hundred and ten undergraduates (Mean age =22.84, SD = 5.31, 83.1% female) completed study materials. We expected that drinking identity and individualism would positively correlate with drinking variables. We further expected that individualism would moderate the association between drinking identity and drinking such that the relationship between drinking identity and alcohol outcomes would be positively associated, particularly among those high in individualism. Our findings supported our hypotheses. These findings better explain the relationship between drinking identity, individualism, and alcohol use. Furthermore, this research encourages the consideration of individual factors and personality characteristics in order to develop culturally tailored materials to maximize intervention efficacy across cultures.

Crying in Context: Understanding Associations With Interpersonal Dependency and Social Support

Directory of Open Access Journals (Sweden)

Katherine L. Fiori

2013-06-01

Full Text Available This study examines the associations among interpersonal dependency, social support, and crying proneness, since crying is a behavior that is particularly relevant to the affiliative interpersonal goals characterizing maladaptive forms of dependency (Keltner & Kring, 1998. Data were collected from 305 first-year university students (M age = 18 years. A series of hierarchical linear regressions, controlling for gender, commuting status, romantic relationship status, stress, loneliness, and depressive symptoms, partially supported our hypotheses. That is, we found that a measure of maladaptive dependency (destructive overdependence, or DO and crying proneness were positively correlated, and that DO moderated the associations between social support and crying proneness. Specifically, we found that social support and crying were more closely positively associated among individuals high on DO compared to individuals low on DO. Our findings imply that interpersonal dependency may be an important factor in understanding individual differences in crying, and in determining whether crying is a successful elicitor of social support.

2014-05-01

Peer support and peer-led family psychoeducation represent two distinct and complementary recovery-oriented models to support individuals who live with schizophrenia and their families, respectively. The goals of these models focus on improving knowledge, coping, self-care, social support, and self-management strategies. These models represent important capacity-building strategies for people who live with the illness and the people who love them. This brief article is intended to provide the practicing clinician, person living with schizophrenia, and policy maker with a working knowledge of the current state of the literature in these two related fields. Practitioners should consider these resources and integrate them into their care. A person living with schizophrenia could use this review to advocate for appropriate resources and to identify career opportunities. Policy makers could benefit from an understanding of the literature to mitigate financial and cultural barriers to adopting these practices. The last 5 years have seen a dramatic expansion of the application of randomized controlled trials (RCTs) to give evidence to match the experience of people in these programs. The field has seen Wellness Recovery Action Plan (WRAP) named as evidence-based practice by the National Registry of Evidence-Based Practices. A RCT was also conducted for another peer-developed and led program called Building Recovery of Individual Dreams & Goals through Education & Support. Family to Family, the largest peer-led family psychoeducation course, was also found to have significant impact after the study and also 6 months later in RCT. Family to Family has also been named as an evidence-based practice. The field of people who are living well with schizophrenia working as resources and supports to others living with the illness is an idea that is growing momentum. This momentum has been matched by the RCT evidence. Peer support as a professional role has an emerging literature

The aim of this study was to investigate the relationship between major recent life events that occurred during the last 5 years, social and personal resources, and subjective quality of life (QoL). A total of 1801 participants from the general population (CoLaus/PsyCoLaus study) completed the Life Events Questionnaire, the Social Support Questionnaire, the NEO Five-Factor Inventory Revised, and the Manchester Short Assessment of Quality of Life. Major life events were modestly associated with the QoL (about 5 % of the explained variance). However, QoL was significantly related to perceived social support and personality traits (about 37 % of the explained variance). Particularly, perceived social support, extraversion and conscientiousness personality dimensions were positively linked to life satisfaction, whereas a high level of neuroticism was negatively associated with QoL. This study highlights the negative but temporary association between critical events and QoL. However, a combination of high conscientiousness and extraversion, and positive social support may explain better variances for a high-perceived QoL.

: Providing medical management updates and long-term support to families with hereditary cancer syndromes in rural areas is a challenge. To address this, we designed a one-day retreat for BRCA1/2 carriers in our region. The retreat included educational updates about medical management, genetic privacy and discrimination, and addressed psychological and family issues. Evaluations completed at the conclusion of the retreat were overwhelmingly positive with requests for a similar event in the future. The impact of this retreat on a variety of health behaviors was assessed. Eligible participants completed questionnaires before and 6 months after the retreat. Questionnaires focused on lifestyle, cancer screening and prevention practices, psychological history and distress, decision-making regarding genetic testing, and family communication issues. For individuals who completed both the pre and post retreat questionnaires, one-half made lifestyle changes and nearly two-thirds increased cancer screening, initiated chemoprevention, completed or planned to complete preventative surgery in the future. We conclude that this type of forum provides a valuable opportunity for BRCA carriers and their families to receive updated medical information, share personal experiences, provide and receive support, as well as change health behaviors.

Obesity Prevention for Individuals with Spina Bifida.

Science.gov (United States)

Polfuss, Michele; Bandini, Linda G; Sawin, Kathleen J

2017-06-01

Obesity is a common comorbidity in individuals with spina bifida. Carrying excess weight exacerbates the inherent health challenges associated with spina bifida, impedes the individual's ability to self-manage their condition, and creates further challenges for family members and caregivers. This manuscript provides a narrative review of key issues for understanding and prevention of obesity in persons with spina bifida within the context of the social ecological model. Specific variables related to obesity and spina bifida include individual factors (i.e., body composition and measurement issues, energy needs, eating patterns, physical activity, and sedentary activity) family factors (i.e., parenting/family, peers), community factors (i.e., culture, built environment, healthcare and healthcare providers, and school), and societal factors (i.e., policy issues). Due to the complex etiology of obesity and its increased prevalence in individuals with spina bifida, it is critical to initiate prevention efforts early with a multifactorial approach for this at-risk population. Increased research is warranted to support these efforts.

Elements for the Design of a Decision-making Information System for activities related to genetically modified organisms: Contributions from a case study

International Nuclear Information System (INIS)

Benavides Molineros, Julia; Aguirre Ramirez, Nestor

2012-01-01

In Colombia, decisions related to genetically modified organisms (GMOs) must be supported by assessment of the risk to biodiversity, human health and agricultural production. Based on this assessment, authorities can make decisions involving authorization or denial of the requested activities. The rationality of the decision-making process is very well established with respect to human health, particularly toxicity and allergenicity, but that is not the case for biodiversity issues. One of the biggest problems in this area is the lack of definition of a decision-making methodology, which leads to decisions made in an intuitive and non-systematic manner. Authorities in the field have recognized the need for a decision-making information system to help solve this situation. A proposal for the basic structure of a decision-making information system oriented to authorities involved in the process is presented. The proposal was developed based on a review of the main existing methodologies for GMO risk assessment and on a case study of the gene flow from GMOs to wild relatives. The structure is presented as a broad entity-relationship model from which the detailed design of the system can be developed. The proposal emphasizes the documentation of the decision protocols and the rationality of use of the information inputs.

Transgender individuals experience discrimination in all domains of their personal and social life. Discrimination is believed to be associated with worse quality of life (QoL). To investigate the relation between QoL and perceived levels of discrimination and social support in individuals with gender dysphoria (GD). Individuals with GD who attended a psychiatry clinic from January 2012 through December 2014 were recruited. Demographic, social, and medical transition features were collected with standardized forms. Self-report measurements of QoL (Turkish version of the World Health Organization's Quality of Life-BREF) that included physical, psychological, social, and environmental domains, perceived discrimination with personal and group subscales (Perceived Discrimination Scale [PDS]), and social support (Multidimensional Scale of Perceived Social Support) were completed. Ninety-four participants (76.6% trans men) adequately completed the study measurements. Regression models with each QoL domain score as a dependent variable indicated a significant predictor value of personal PDS in social and environmental QoL. Social support from family was associated with better QoL in psychological QoL, whereas perceived support from friends significantly predicted all other domains of QoL. There was a tendency for group PDS to be rated higher than personal PDS, suggesting personal vs group discrimination discrepancy. However, group PDS was not found to be a predictor of QoL in the multivariate model. Perceived personal discrimination and social support from different sources predicted domains of QoL with a non-uniform pattern in individuals with GD. Social support and discrimination were found to have opposing contributions to QoL in GD. The present findings emphasize the necessity of addressing discrimination and social support in clinical work with GD. Moreover, strategies to improve and strengthen friend and family support for individuals with GD should be explored by

Duty or dream? Edwin G. Conklin's critique of eugenics and support for American individualism.

Science.gov (United States)

Cooke, Kathy J

2002-01-01

This paper assesses ideas about moral and reproductive duty in American eugenics during the early twentieth century. While extreme eugenicists, including Charles Davenport and Paul Popenoe, argued that social leaders and biologists must work to prevent individuals who were "unfit" from reproducing, moderates, especially Edwin G. Conklin, presented a different view. Although he was sympathetic to eugenic goals and participated in eugenic organizations throughout his life, Conklin realized that eugenic ideas rarely could meet strict hereditary measures. Relying on his experience as an embryologist, Conklin instead attempted to balance more extreme eugenic claims - that emphasized the absolute limits posed by heredity - with his own view of "the possibilities of development." Through his critique he argued that most human beings never even begin to approach their hereditary potential; he moderated his own eugenic rhetoric so that it preserved individual opportunity and responsibility, or what has often been labeled the American Dream.

Gustafsson, Christine; Fagerberg, Ingegerd; Asp, Margareta

2010-10-01

The aim of the present study was to examine the support night nurses' give to staff in community night nursing. Studies have shown that support given to staff is one of night registered nurses' (RNs') experiences of the meaning of caring. This support, that community RNs display for staff in night-time care, is sparsely described. All community night-duty nurses in a medium-sized municipal in Sweden participated in the present study. Thematic content analysis was used to analyse data from observations. The support given by RNs to staff is described using three themes: (1) a conditional supporting stance, (2) preparing propitious conditions for caring and (3) confidence in the abilities of individual staff members and adaptation to their individual needs. The results reveal that RNs consider support to staff in terms of nursing leadership. Out of 'concern for the staff' the RNs try to be there for them, which corresponds to nursing leadership. Such concern also arises from the RNs' awareness that by giving support to staff this affects the staffs' caring for older people. The current municipal social care organization of community nursing of older people in which RNs have extensive responsibilities with insufficient control, is a working condition with a risk for decreased quality of care and a high risk for work-related stress syndrome. © 2010 The Authors.

OBJECTIVE To analyze the prevalence of individuals at risk of dependence and its associated factors. METHODS The study was based on data from the Catalan Health Survey, Spain conducted in 2010 and 2011. Logistic regression models from a random sample of 3,842 individuals aged ≥ 15 years were used to classify individuals according to the state of their personal autonomy. Predictive models were proposed to identify indicators that helped distinguish dependent individuals from those at risk of dependence. Variables on health status, social support, and lifestyles were considered. RESULTS We found that 18.6% of the population presented a risk of dependence, especially after age 65. Compared with this group, individuals who reported dependence (11.0%) had difficulties performing activities of daily living and had to receive support to perform them. Habits such as smoking, excessive alcohol consumption, and being sedentary were associated with a higher probability of dependence, particularly for women. CONCLUSIONS Difficulties in carrying out activities of daily living precede the onset of dependence. Preserving personal autonomy and function without receiving support appear to be a preventive factor. Adopting an active and healthy lifestyle helps reduce the risk of dependence.

Supporting Success for All Students

The geoscience student population in the United States today does not reflect the diversity of the US population. Not only does this challenge our ability to educate sufficient numbers of students in the geosciences, it also challenges our ability to address issues of environmental justice, to bring geoscience expertise to diverse communities, and to pursue a research agenda reflecting the needs and interests of our nation as a whole. Programs that are successful in supporting students from underrepresented groups attend to the whole student (Jolly et al, 2004) as they develop not only knowledge and skills, but a sense of belonging and a drive to succeed in geoscience. The whole student approach provides a framework for supporting the success of all students, be they members of underrepresented groups or not. Important aspects of support include mentoring and advising, academic support, an inclusive learning community, and opportunities to learn about the profession and to develop geoscience and professional skills. To successfully provide support for the full range of students, it is critical to consider not only what opportunities are available but the barriers different types of students face in accessing these opportunities. Barriers may arise from gaps in academic experiences, crossing into a new and unfamiliar culture, lack of confidence, stereotype threat, implicit bias and other sources. Isolation of geoscience learning from its application and social context may preferentially discourage some groups. Action can be taken to increase support for all students within an individual course, a department or an institution. The InTeGrate STEP Center for the Geosciences, the Supporting and Advancing Geoscience Education at Two-Year Colleges program and the On the Cutting Edge Professional Development for Geoscience Faculty program all provide resources for individuals and departments including on line information, program descriptions, and workshop opportunities.

This paper describes the pipe support program at Pickering. The program addresses the highest priority in operating nuclear generating stations, safety. We present the need: safety, the process: managed and strategic, and the result: assurance of critical piping integrity. In the past, surveillance programs periodically inspected some systems, equipment, and individual components. This comprehensive program is based on a managed process that assesses risk to identify critical piping systems and supports and to develop a strategy for surveillance and maintenance. The strategy addresses all critical piping supports. Successful implementation of the program has provided assurance of critical piping and support integrity and has contributed to decreasing probability of pipe failure, reducing risk to worker and public safety, improving configuration management, and reducing probability of production losses.

2018-03-01

The "out of the blue" nature of recent terror attacks and the diversity of apparent motives highlight the importance of understanding the online trajectories that individuals follow prior to developing high levels of extremist support. Here we show that the physics of stochastic walks, with and without temporal correlation, provides a unifying description of these online trajectories. Our unique data set comprising all users of a global social media site reveals universal characteristics in individuals' online lifetimes. Our accompanying theory generates analytical and numerical solutions that describe the characteristics shown by individuals that go on to develop high levels of extremist support and those that do not. Going forward, it is conceivable that a deeper understanding of these temporal and many-body correlations may eventually contribute to the important task of better countering the spread of radical propaganda online.

Dobnik, David; Morisset, Dany; Gruden, Kristina

2010-03-01

In the field of genetically modified organism (GMO) diagnostics, real-time PCR has been the method of choice for target detection and quantification in most laboratories. Despite its numerous advantages, however, the lack of a true multiplexing option may render real-time PCR less practical in the face of future GMO detection challenges such as the multiplicity and increasing complexity of new transgenic events, as well as the repeated occurrence of unauthorized GMOs on the market. In this context, we recently reported the development of a novel multiplex quantitative DNA-based target amplification method, named NASBA implemented microarray analysis (NAIMA), which is suitable for sensitive, specific and quantitative detection of GMOs on a microarray. In this article, the performance of NAIMA is compared with that of real-time PCR, the focus being their performances in view of the upcoming challenge to detect/quantify an increasing number of possible GMOs at a sustainable cost and affordable staff effort. Finally, we present our conclusions concerning the applicability of NAIMA for future use in GMO diagnostics.

Risk analysis of bioprocesses based on genetically modified bacteria. Pathway and exposure modeling

Energy Technology Data Exchange (ETDEWEB)

Rein, A.; Bittens, M. [Tuebingen Univ. (Germany). Zentrum fuer Angewandte Geowissenschaften

2003-07-01

For soils contaminated with polychlorinated biphenyls (PCBs), a plant-microorganism system for in situ - bioremediation has been developed. It consists of genetically modified microorganisms (GMOs) in conjunction with plant roots. The GMOs are Pseudomonas fluorescens strains which are genetically engineered to degrade PCB congeners in situ. Their metabolism requires root exudates and is therefore tightly coupled to plant rhizospheres. Compared to wild type organisms, the genetically modified bacteria develop a specificity to PCB as a substrate and therefore foster biodegradation in a more efficient way. To evaluate the efficiency and impact of this bioremediation system for potential field application, lysimeter tests are carried out. The lysimeters are filled with contaminated soil from a PCB release site in Denmark and planted with GMO inoculated plants. On the basis of these experiments, a detailed risk analysis is carried out to obtain conclusions to field-conditions (potential deliberate GMO-release). A qualitative and quantitative assessment of actual or potential effects is performed, addressing transport, fate and exposure of PCBs, GMOs and specific degradation products in different environmental compartments.

The Value of Caregiver Time: Costs of Support and Care for Individuals Living with Autism Spectrum Disorder

Carolyn Dudley

2016-01-01

Full Text Available WHY IS THIS AN IMPORTANT ISSUE? An estimated 1 in 86 children are diagnosed with Autism Spectrum Disorder (ASD1 making it the most commonly diagnosed childhood neurological condition in Canada.2 The true costs of lifelong support for people living with ASD3 are often underestimated and fail to acknowledge the value of caregiver time over the lifespan. Significant gaps in publically provided support systems leave the cost burden to be picked up by families. Relying on continued family supports where community services are fragmented or unavailable is not a sustainable approach. WHAT DOES THE RESEARCH TELL US? A continuum of supports are needed Most people living with ASD need supports that range from occasional assistance with higher level tasks, like organizing appointments or banking, to those who need continuous help with daily living.4 Areas where supportive care may be needed can be categorized broadly to include: self care, home living, service co-ordination, personal organization, health and safety management, adult day opportunities/employment, transportation, advocacy and social skills. These supports are most successful when they address the individual’s uniqueness in terms of communication, social, sensory, behavioural needs and physical and/or mental health conditions. Currently there are a lack of available supports, limiting opportunities for socialization, employment and residential living resulting in reduced independence for adults with ASD.

Arguments for such a statement are found primarily in the potential issues that intentional breeding of GMOs might inflict upon the human health and environment.

Body weight-supported treadmill training (BWSTT) has produced mixed results compared with other therapeutic techniques. The purpose of this study was to determine whether an intensive intervention (intensive mobility training) including BWSTT provides superior gait, balance, and mobility outcomes compared with a similar intervention with overground gait training in place of BWSTT. Forty-three individuals with chronic stroke (mean [SD] age, 61.5 [13.5] years; mean [SD] time since stroke, 3.3 [3.8] years), were randomized to a treatment (BWSTT, n = 23) or control (overground gait training, n = 20) group. Treatment consisted of 1 hour of gait training; 1 hour of balance activities; and 1 hour of strength, range of motion, and coordination for 10 consecutive weekdays (30 hours). Assessments (step length differential, self-selected and fast walking speed, 6-minute walk test, Berg Balance Scale [BBS], Dynamic Gait Index [DGI], Activities-specific Balance Confidence [ABC] scale, single limb stance, Timed Up and Go [TUG], Fugl-Meyer [FM], and perceived recovery [PR]) were conducted before, immediately after, and 3 months after intervention. No significant differences (α = 0.05) were found between groups after training or at follow-up; therefore, groups were combined for remaining analyses. Significant differences (α = 0.05) were found pretest to posttest for fast walking speed, BBS, DGI, ABC, TUG, FM, and PR. DGI, ABC, TUG, and PR results remained significant at follow-up. Effect sizes were small to moderate in the direction of improvement. Future studies should investigate the effectiveness of intensive interventions of durations greater than 10 days for improving gait, balance, and mobility in individuals with chronic stroke.

Despite the importance of tending to older individuals who are vulnerable to suicide, little is known about suicidal ideation in the portion of this population receiving home-care services in Asian countries. The objective of this cross-sectional study was to examine predictors of suicidal ideation in older individuals using home-care service. Participants were randomly selected from the individuals 50 years old and over using home-care services across Jeollabuk-do Province, Korea. A total of 697 subjects participated in this study. Each participant completed the short version of the Geriatric Depression Scale, the Scale for Suicidal Ideation, the Multidimensional Scale of Perceived Social Support, and the World Health Organization Disability Assessment Schedule II. Hierarchical regression analyses revealed that depression, perceived social support, and disability were significant predictors of suicidal ideation, whereas the roles of subjective health status and fish consumption remained ambiguous in this regard. In terms of social support, we also found that less perceived social support from family members was related to higher levels of suicidal ideation. The associations between various categories of disability and suicidal ideation disappeared after controlling for depression. Our investigation of the mediating effect of depression on the relationship between disability and suicidal ideation revealed that depression was either a complete (disability related to cognition, self-care, getting along with others, and life activities) or partial (disability related to participation) mediator. Preventive strategies focusing on depression, social support, and disability should be emphasized during encounters with older people receiving home-care services.

To examine the feasibility and potential benefits of early peer support to improve the health and quality of life of individuals with early inflammatory arthritis (EIA). Feasibility study using the 2008 Medical Research Council framework as a theoretical basis. A literature review, environmental scan, and interviews with patients, families and healthcare providers guided the development of peer mentor training sessions and a peer-to-peer mentoring programme. Peer mentors were trained and paired with a mentee to receive (face-to-face or telephone) support over 12 weeks. Two academic teaching hospitals in Toronto, Ontario, Canada. Nine pairs consisting of one peer mentor and one mentee were matched based on factors such as age and work status. Mentee outcomes of disease modifying antirheumatic drugs (DMARDs)/biological treatment use, self-efficacy, self-management, health-related quality of life, anxiety, coping efficacy, social support and disease activity were measured using validated tools. Descriptive statistics and effect sizes were calculated to determine clinically important (>0.3) changes. Peer mentor self-efficacy was assessed using a self-efficacy scale. Interviews conducted with participants examined acceptability and feasibility of procedures and outcome measures, as well as perspectives on the value of peer support for individuals with EIA. Themes were identified through constant comparison. Mentees experienced improvements in the overall arthritis impact on life, coping efficacy and social support (effect size >0.3). Mentees also perceived emotional, informational, appraisal and instrumental support. Mentors also reported benefits and learnt from mentees' fortitude and self-management skills. The training was well received by mentors. Their self-efficacy increased significantly after training completion. Participants' experience of peer support was informed by the unique relationship with their peer. All participants were unequivocal about the need for

[The sick individual as a concept].

Science.gov (United States)

Tejerizo López, Luis Carlos

2011-01-01

, this paper supports the philosophical idea of the creation of a new concept: We have to create the concept of the sick with a philosophical basis, we must establish the idea that the sick individual lives, since the very moment he starts being sick, in a new and different time. The sick individual lives in a different time and, if we identify--with a certain boldness, just as Esquirol points out--"time" and "life", then we shall be bold enough to create a new entity, the sick individual, whose circumstances and new supports turn him into a new concept, they turn him into an idea--which shall be well defined and better shaped--after which we can think and act according to the belief of the sick individual as a concept, which is radically different from the healthy individual as a concept. The sick individual has nothing to do, if we can say so with a certain emphasis, with the healthy individual. They live in different times, although those times are not entirely unknown for each other. Every individual has the ability of thought. I think that the doctor, now become philosopher, must integrate the creation in its routine in order to be a better professional. He must create the concept of the sick individual, whose time has more different connotations than those found in the healthy individual. Accordingly, we want to think that the fabricated reality of the time of the healthy individual is not useful anymore, because the sick individual is an entity "in the distance", in which the course of time is fragmented as soon as he assimilates the crisis brought by the sickness. We have to properly shape and define that crisis and use it to philosophically establish the concept of the sick individual. Our plan is to produce a book after this conference.

Social Anxiety and Social Support in Romantic Relationships.

Porter, Eliora; Chambless, Dianne L

Little is known about the quality of socially anxious individuals' romantic relationships. In the present study, we examine associations between social anxiety and social support in such relationships. In Study 1, we collected self-report data on social anxiety symptoms and received, provided, and perceived social support from 343 undergraduates and their romantic partners. One year later couples were contacted to determine whether they were still in this relationship. Results indicated that men's social anxiety at Time 1 predicted higher rates of breakup at Time 2. Men's and women's perceived support, as well as men's provided support, were also significantly predictive of breakup. Social anxiety did not interact with any of the support variables to predict breakup. In Study 2, a subset of undergraduate couples with a partner high (n=27) or low (n=27) in social anxiety completed two 10-minute, lab-based, video-recorded social support tasks. Both partners rated their received or provided social support following the interaction, and trained observers also coded for support behaviors. Results showed that socially anxious individuals received less support from their partners during the interaction according to participant but not observer report. High and lower social anxiety couples did not differ in terms of the target's provision of support. Taken together, results suggest that social anxiety is associated with difficulties even in the context of established romantic relationships. Clinical implications are discussed. Copyright © 2016.

2017-01-01

The aspiration of biology education is to give students tools to apply knowledge learned in the classroom to everyday life. Genetic modification is a real-world biological concept that relies on an in-depth understanding of the molecular behavior of DNA and proteins. This study investigated undergraduate biology students' conceptions of genetically modified organisms (GMOs) when probed with real-world, molecular and cellular, and essentialist cues, and how those conceptions compared across biology expertise. We developed a novel written assessment tool and administered it to 120 non-biology majors, 154 entering biology majors, 120 advanced biology majors (ABM), and nine biology faculty. Results indicated that undergraduate biology majors rarely included molecular and cellular rationales in their initial explanations of GMOs. Despite ABM demonstrating that they have much of the biology knowledge necessary to understand genetic modification, they did not appear to apply this knowledge to explaining GMOs. Further, this study showed that all undergraduate student populations exhibited evidence of essentialist thinking while explaining GMOs, regardless of their level of biology training. Finally, our results suggest an association between scientifically accurate ideas and the application of molecular and cellular rationales, as well as an association between misconceptions and essentialist rationales. © 2017 L.

Background Permanent supportive housing (PSH) is the leading intervention to end chronic homelessness. Little is known, however, about gender differences, including potential disparities in physical and mental health and social support, that might inform services available through PSH. Methods 421 homeless adults, at least 39 years old, English- or Spanish-speaking, who were moving into PSH through 26 different agencies in the Los Angeles area participated. Results Compared to men entering PSH, homeless women (28% of the sample) were younger (phomeless adults moving into PSH. PSH cannot be a one-size-fits-all approach. Supportive services within housing should be tailored based on gender and other individual needs. PMID:28153741

Values of dose and individual of a individual thermoluminescent dosimeter submitted to x and gamma radiations

The individual monitoring provides information for the control of exposures, and estimates the dose received by individuals. This is an essential tool in personal dosimetry. It's based on a radiation protection concept, allowing an individual exposure control, besides guaranteeing that the dose restrictions will not be exceeded. Usually, the dose monitoring is performed by using an individual dosemeter placed on a representative position of the most exposed point on the thoracic surface. The dosemeter, which is analyzed in the present work, is made of three CaSO 4 -Dy thermoluminescent detectors, plastic filters, copper and copper-lead, mounted in an acrylic support. The dose received by on each detector, which forms the dosemeter, is related according to their energetic curve dependence. The dose amount is calculated from these curves by using an algorithm, and it was taken in to consideration the detector calibration and thermoluminescent responses, due to the x and g radiation exposure. That algorithm has the capacity to determine the energies that were irradiated the detector. Therefore, to aid the service in the moment of evaluate the dose received by the individual and where it is coming from. The algorithm has provided individual dose value H x , defined as operational quantity for photons adopted in the Brazilian Metric System. The algorithm can determine two dose values and such values have been analyzed according to the kind of irradiated energy on the dosimeter and it has shown that both values are within established limits by Instituto de Radioprotecao e Dosimetria (IRD).

The effect of Individual Placement and Support (IPS) on return to work or education among people with mood or anxiety disorders is unclear, while IPS increases return to work for people with severe mental illness. We examined the effect of IPS modified for people with mood and anxiety disorders (IPS-MA) on return to work and education compared with services as usual (SAU). In a randomised clinical superiority trial, 326 participants with mood and anxiety disorders were centrally randomised to IPS-MA, consisting of individual mentor support and career counselling (n=162) or SAU (n=164). The primary outcome was competitive employment or education at 24 months, while weeks of competitive employment or education, illness symptoms and level of functioning, and well-being were secondary outcomes. After 24 months, 44.4% (72/162) of the participants receiving IPS-MA had returned to work or education compared with 37.8% (62/164) following SAU (OR=1.34, 95% CI: 0.86 to 2.10, p=0.20). We found no difference in mean number of weeks in employment or education (IPS-MA 32.4 weeks vs SAU 26.7 weeks, p=0.14), level of depression (Hamilton Depression 6-Item Scale score IPS-MA 5.7 points vs SAU 5.0 points, p=0.12), level of anxiety (Hamilton Anxiety 6-Item Scale score IPS-MA 5.8 points vs SAU 5.1 points, p=0.17), level of functioning (Global Assessment of Functioning IPS-MA 59.1 points vs SAU 59.5 points, p=0.81) or well-being measured by WHO-Five Well-being Index (IPS-MA 49.6 points vs SAU 48.5 points, p=0.83) at 24 months. The modified version of IPS, IPS-MA, was not superior to SAU in supporting people with mood or anxiety disorders in return to work at 24 months.

A 41-year-old man with a history of C6 American Spinal Injury Association (ASIA) Impairment Scale (AIS) C spinal cord injury (SCI), enrolled in an Institutional Review Board (IRB)-approved, robotic-assisted body weight-supported treadmill training (BWSTT), and aquatic exercise research protocol developed asymptomatic autonomic dysreflexia (AD) during training. Little information is available regarding the relationship of robotic-assisted BWSTT and AD. After successfully completing 36 sessions of aquatic exercise, he reported exertional fatigue during his 10th Lokomat intervention and exhibited asymptomatic or silent AD during this and the three subsequent BWSTT sessions. Standard facilitators of AD were assessed and no obvious irritant identified other than the actual physical exertion and positioning required during robotic-assisted BWSTT. Increased awareness of potential silent AD presenting during robotic assisted BWSTT training for individuals with motor incomplete SCI is required as in this case AD clinical signs were not concurrent with occurrence. Frequent vital sign assessment before, during, and at conclusion of each BWSTT session is strongly recommended.

Recent World Health Organization HIV treatment guideline expansion may facilitate timely antiretroviral therapy (ART) initiation. However, large-scale success of universal treatment strategies requires a more comprehensive understanding of known barriers to early ART initiation. This work aims to advance a more comprehensive understanding of interrelationships among three known barriers to ART initiation: psychological distress, HIV-related stigma, and low social support. We analyzed cross-sectional interview data on 1175 adults initiating ART at six HIV treatment clinics in Ethiopia. Experience of each form of HIV-related stigma assessed (e.g., anticipatory, internalized, and enacted) was associated with increased odds of psychological distress. However, among those who reported enacted HIV-related stigma, there was no significant association between social support and psychological distress. Interventions to improve mental health among people living with HIV should consider incorporating components to address stigma, focusing on strategies to prevent or reduce the internalization of stigma, given the magnitude of the relationship between high internalized stigma and psychological distress. Interventions to increase social support may be insufficient to improve the mental health of people living with HIV who experienced enacted HIV-related stigma. Future research should examine alternative strategies to manage the mental health consequences of enacted HIV-related stigma, including coping skills training.

Background People in the early stages of dementia adjust to the illness through stages of awareness, coping, and evaluation. Studies have found that hope, social support, and self-esteem facilitate coping, adjustment, and adaptation in chronic illness. Objective The purpose of this descriptive study was to examine the relationships between hope, social support, and self-esteem in individuals with early stage dementia. Methods Data were obtained from 53 individuals with early stage dementia. The scores on the Herth Hope Index, Social Support Questionnaire Short-Form, and the State Self-Esteem Scale were analyzed using linear regression. Results Hope was moderately associated with self-esteem ( r = .49, p self-esteem and was a key component in predicting self-esteem. No significant relationship was found between social support and self-esteem. Conclusion Findings suggest that hope may be an important factor to help individuals manage potential threats to self-esteem in the experience of early stage dementia. Strategies to inspire hope and then enhance self-esteem are promising for individuals living with early stage dementia.

Political economy. On the endogeneity of political preferences: evidence from individual experience with democracy.

Fuchs-Schündeln, Nicola; Schündeln, Matthias

2015-03-06

Democracies depend on the support of the general population, but little is known about the determinants of this support. We investigated whether support for democracy increases with the length of time spent under the system and whether preferences are thus affected by the political system. Relying on 380,000 individual-level observations from 104 countries over the years 1994 to 2013, and exploiting individual-level variation within a country and a given year in the length of time spent under democracy, we find evidence that political preferences are endogenous. For new democracies, our findings imply that popular support needs time to develop. For example, the effect of around 8.5 more years of democratic experience corresponds to the difference in support for democracy between primary and secondary education.

Beckner, Victoria; Howard, Isa; Vella, Lea; Mohr, David C

2010-02-01

Depression is common in individuals with multiple sclerosis (MS). While psychotherapy is an effective treatment for depression, not all individuals benefit. We examined whether baseline social support might differentially affect treatment outcome in 127 participants with MS and depression randomized to either Telephone-administered Cognitive-Behavioral Therapy (T-CBT) or Telephone-administered Emotion-Focused Therapy (T-EFT). We predicted that those with low social support would improve more in T-EFT, since this approach emphasizes the therapeutic relationship, while participants with strong social networks and presumably more emotional resources might fare better in the more structured and demanding T-CBT. We found that both level of received support and satisfaction with that support at baseline did moderate treatment outcome. Individuals with high social support showed a greater reduction in depressive symptoms in the T-CBT as predicted, but participants with low social support showed a similar reduction in both treatments. This suggests that for participants with high social support, CBT may be a more beneficial treatment for depression compared with EFT.

South African student nurses experience emotional discomfort that might influence their adjustment and coping while working with mentally challenged individuals. Adjustment and coping might impact on their mental health and support needed while working in this challenging context. Student nurses working with mentally challenged individuals experience emotional discomfort that may result in work-related stress. The experiences of student nurses working with mentally challenged individuals were explored and described as it may influence their adjustment, coping and result in work-related stress, impacting on their mental health. The study used a qualitative, explorative, descriptive, contextual research design with a case study as strategy. Thirteen student nurses from a specific higher educational institution in Gauteng, South Africa, participated in the focus group interviews. The researcher utilized reflective journals, a reflective letter, naïve sketches, drawings and field notes to collect data. Data analysis was done according to Tesch's descriptive method of open coding and theme analysis. A central storyline emerged where student nurses described working with mentally challenged individuals as a process of personal transformation that was initiated by an engagement on a deeper emotional level with these individuals. The process of personal transformation started a journey towards the discovery of meaning for the self, as student nurses. Student nurses working in challenging environments during their training may experience emotional discomfort and need additional support in coping and adjustment within this context. The nurse educator plays an important role in providing this support to manage work-related stress as well as in creating learning opportunities for the student nurses working in challenging contexts. © 2012 Blackwell Publishing.

Full Text Available Learning is one of the most important aspects of children's behaviour. A new theory that emerged from evolutionary principles and information-processing models assumes learning to be run by two basic mechanisms: variability and selection. The theory is based on the underlying assumption that intra-individual variability of strategies that children use to solve a problem, is a core mechanism of learning change. This assumption was tested in the case of multiple classification (MC task. 30 6-year-old children were tested for intelligence, short-term memory, and MC. Procedure followed classical pre-test/learning/post-test scheme. Amount of learning was measured through percentage of correct answers before and after learning sessions, whereas intra-individual variability was assessed through children's explanations of their answers on MC problems. The results yielded intra-individual variability to explain learning changes beyond inter-individual differences in intelligence or short-term memory. Although the results rose some new questions to be considered in further research, the data supported the hypothesis of intra-individual variability as predictor of learning change.
