Axiomatizing GSOS with Predicates

Directory of Open Access Journals (Sweden)

Luca Aceto

2011-08-01

Full Text Available In this paper, we introduce an extension of the GSOS rule format with predicates such as termination, convergence and divergence. For this format we generalize the technique proposed by Aceto, Bloom and Vaandrager for the automatic generation of ground-complete axiomatizations of bisimilarity over GSOS systems. Our procedure is implemented in a tool that receives SOS specifications as input and derives the corresponding axiomatizations automatically. This paves the way to checking strong bisimilarity over process terms by means of theorem-proving techniques.

Lexical development of noun and predicate comprehension and production in isiZulu.

Science.gov (United States)

Nicolas, Ramona Kunene; Ahmed, Saaliha

2016-07-28

This study seeks to investigate the development of noun and predicate comprehension and production in isiZulu-speaking children between the ages of 25 and 36 months. It compares lexical comprehension and production in isiZulu, using an Italian developed and validated vocabulary assessment tool: The Picture Naming Game (PiNG) developed by Bello, Giannantoni, Pettenati, Stefanini and Caselli (2012). The PiNG tool includes four subtests, one each for subnoun comprehension (NC), noun production (NP), predicate comprehension (PC), and predicate production (PP). Children are shown these lexical items and then asked to show comprehension and produce certain lexical items. After adaptation into the South African context, the adapted version of PiNG was used to directly assess the lexical development of isiZulu with the three main objectives to (1) test the efficiency of the adaptation of a vocabulary tool to measure isiZulu comprehension and production development, (2) test previous findings done in many cross-linguistic comparisons that have found that both comprehension and production performance increase with age for a lesser-studied language, and (3) present our findings around the comprehension and production of the linguistic categories of nouns and predicates. An analysis of the results reported in this study show an age effect throughout the entire sample. Across all the age groups, the comprehension of the noun and predicate subtests was better performed than the production of noun and predicate subtests. With regard to lexical items, the responses of children showed an influence of various factors, including the late acquisition of items, possible problems with stimuli presented to them, and the possible input received by the children from their home environment.

EXPANSION OF TURBO PROLOGUE PROGRAMMING SYSTEM BY PREDICATES FOR LIST PROCESSING

Directory of Open Access Journals (Sweden)

A. T. Kovalkov

2008-01-01

Full Text Available Lists are considered as a main data structure in logic Turbo Prologue programming language. However the language does not contain in-set predicates (procedures for list processing. In order to facilitate a problem programming process where lists are used it is proposed to apply a Turbo Prologue version that has a set of predicates in the form of recursive rules for executing frequently repeated operations with lists such as unification of lists, italicization and deletion of some list elements, sorting-out, list reversing and many others. The modified version contains a reference to new input predicates. The proposed Turbo Prologue version is easily expanded by new rules. Usage of this version makes programmer’s work easier and promotes development of new programs where it is necessary to work with lists.

Potential Risk Estimation Drowning Index for Children (PREDIC): a pilot study from Matlab, Bangladesh.

Science.gov (United States)

Borse, N N; Hyder, A A; Bishai, D; Baker, T; Arifeen, S E

2011-11-01

Childhood drowning is a major public health problem that has been neglected in many low- and middle-income countries. In Matlab, rural Bangladesh, more than 40% of child deaths aged 1-4 years are due to drowning. The main objective of this paper was to develop and evaluate a childhood drowning risk prediction index. A literature review was carried out to document risk factors identified for childhood drowning in Bangladesh. The Newacheck model for special health care needs for children was adapted and applied to construct a childhood drowning risk index called "Potential Risk Estimation Drowning Index for Children" (PREDIC). Finally, the proposed PREDIC Index was applied to childhood drowning deaths and compared with the comparison group from children living in Matlab, Bangladesh. This pilot study used t-tests and Receiver Operating Characteristic (ROC) curve to analyze the results. The PREDIC index was applied to 302 drowning deaths and 624 children 0-4 years old living in Matlab. The results of t-test indicate that the drowned children had a statistically (t=-8.58, p=0.0001) significant higher mean PREDIC score (6.01) than those in comparison group (5.26). Drowning cases had a PREDIC score of 6 or more for 68% of the children however, the comparison group had 43% of the children with score of 6 or more which was statistically significant (t=-7.36, p<0.001). The area under the curve for the Receiver Operating Characteristic curve was 0.662. Index score construction was scientifically plausible; and the index is relatively complete, fairly accurate, and practical. The risk index can help identify and target high risk children with drowning prevention programs. PREDIC index needs to be further tested for its accuracy, feasibility and effectiveness in drowning risk reduction in Bangladesh and other countries. Copyright © 2011 Elsevier Ltd.

Semantic role labeling for protein transport predicates

Directory of Open Access Journals (Sweden)

Martin James H

2008-06-01

Full Text Available Abstract Background Automatic semantic role labeling (SRL is a natural language processing (NLP technique that maps sentences to semantic representations. This technique has been widely studied in the recent years, but mostly with data in newswire domains. Here, we report on a SRL model for identifying the semantic roles of biomedical predicates describing protein transport in GeneRIFs – manually curated sentences focusing on gene functions. To avoid the computational cost of syntactic parsing, and because the boundaries of our protein transport roles often did not match up with syntactic phrase boundaries, we approached this problem with a word-chunking paradigm and trained support vector machine classifiers to classify words as being at the beginning, inside or outside of a protein transport role. Results We collected a set of 837 GeneRIFs describing movements of proteins between cellular components, whose predicates were annotated for the semantic roles AGENT, PATIENT, ORIGIN and DESTINATION. We trained these models with the features of previous word-chunking models, features adapted from phrase-chunking models, and features derived from an analysis of our data. Our models were able to label protein transport semantic roles with 87.6% precision and 79.0% recall when using manually annotated protein boundaries, and 87.0% precision and 74.5% recall when using automatically identified ones. Conclusion We successfully adapted the word-chunking classification paradigm to semantic role labeling, applying it to a new domain with predicates completely absent from any previous studies. By combining the traditional word and phrasal role labeling features with biomedical features like protein boundaries and MEDPOST part of speech tags, we were able to address the challenges posed by the new domain data and subsequently build robust models that achieved F-measures as high as 83.1. This system for extracting protein transport information from Gene

Cao Huimo

1995-03-01

The commonly adopted deposit model method in mineral resources predication has two main part: one is model data that show up geological mineralization law for deposit, the other is statistics predication method that accords with characters of the data namely pretty regression method. This kind of regression method may be called finding-equal regression, which is made of the linear regression and distribution finding-equal method. Because distribution finding-equal method is a data pretreatment which accords with advanced mathematical precondition for the linear regression namely equal distribution theory, and this kind of data pretreatment is possible of realization. Therefore finding-equal regression not only can overcome nonlinear limitations, that are commonly occurred in traditional linear regression or other regression and always have no solution, but also can distinguish outliers and eliminate its weak influence, which would usually appeared when Robust regression possesses outlier in independent variables. Thus this newly finding-equal regression stands the best status in all kind of regression methods. Finally, two good examples of U resource quantitative predication are provided

Spatial Relation Predicates in Topographic Feature Semantics

Science.gov (United States)

Varanka, Dalia E.; Caro, Holly K.

2013-01-01

Topographic data are designed and widely used for base maps of diverse applications, yet the power of these information sources largely relies on the interpretive skills of map readers and relational database expert users once the data are in map or geographic information system (GIS) form. Advances in geospatial semantic technology offer data model alternatives for explicating concepts and articulating complex data queries and statements. To understand and enrich the vocabulary of topographic feature properties for semantic technology, English language spatial relation predicates were analyzed in three standard topographic feature glossaries. The analytical approach drew from disciplinary concepts in geography, linguistics, and information science. Five major classes of spatial relation predicates were identified from the analysis; representations for most of these are not widely available. The classes are: part-whole (which are commonly modeled throughout semantic and linked-data networks), geometric, processes, human intention, and spatial prepositions. These are commonly found in the ‘real world’ and support the environmental science basis for digital topographical mapping. The spatial relation concepts are based on sets of relation terms presented in this chapter, though these lists are not prescriptive or exhaustive. The results of this study make explicit the concepts forming a broad set of spatial relation expressions, which in turn form the basis for expanding the range of possible queries for topographical data analysis and mapping.

Development and evaluation of a biomedical search engine using a predicate-based vector space model.

Although biomedical information available in articles and patents is increasing exponentially, we continue to rely on the same information retrieval methods and use very few keywords to search millions of documents. We are developing a fundamentally different approach for finding much more precise and complete information with a single query using predicates instead of keywords for both query and document representation. Predicates are triples that are more complex datastructures than keywords and contain more structured information. To make optimal use of them, we developed a new predicate-based vector space model and query-document similarity function with adjusted tf-idf and boost function. Using a test bed of 107,367 PubMed abstracts, we evaluated the first essential function: retrieving information. Cancer researchers provided 20 realistic queries, for which the top 15 abstracts were retrieved using a predicate-based (new) and keyword-based (baseline) approach. Each abstract was evaluated, double-blind, by cancer researchers on a 0-5 point scale to calculate precision (0 versus higher) and relevance (0-5 score). Precision was significantly higher (psearching than keywords, laying the foundation for rich and sophisticated information search. Copyright © 2013 Elsevier Inc. All rights reserved.

PASBio: predicate-argument structures for event extraction in molecular biology

Science.gov (United States)

Wattarujeekrit, Tuangthong; Shah, Parantu K; Collier, Nigel

2004-01-01

Background The exploitation of information extraction (IE), a technology aiming to provide instances of structured representations from free-form text, has been rapidly growing within the molecular biology (MB) research community to keep track of the latest results reported in literature. IE systems have traditionally used shallow syntactic patterns for matching facts in sentences but such approaches appear inadequate to achieve high accuracy in MB event extraction due to complex sentence structure. A consensus in the IE community is emerging on the necessity for exploiting deeper knowledge structures such as through the relations between a verb and its arguments shown by predicate-argument structure (PAS). PAS is of interest as structures typically correspond to events of interest and their participating entities. For this to be realized within IE a key knowledge component is the definition of PAS frames. PAS frames for non-technical domains such as newswire are already being constructed in several projects such as PropBank, VerbNet, and FrameNet. Knowledge from PAS should enable more accurate applications in several areas where sentence understanding is required like machine translation and text summarization. In this article, we explore the need to adapt PAS for the MB domain and specify PAS frames to support IE, as well as outlining the major issues that require consideration in their construction. Results We introduce PASBio by extending a model based on PropBank to the MB domain. The hypothesis we explore is that PAS holds the key for understanding relationships describing the roles of genes and gene products in mediating their biological functions. We chose predicates describing gene expression, molecular interactions and signal transduction events with the aim of covering a number of research areas in MB. Analysis was performed on sentences containing a set of verbal predicates from MEDLINE and full text journals. Results confirm the necessity to analyze

Hospitalization in chronic heart failure patients associated with high mortality and morbidity rate. The 90 days post-discharge period following hospitalization in heart failure patients is known as the vulnerable phase, it carries the high risk of poor outcomes. Identification of high-risk individuals by using prognostic evaluation was intended to do a closer follow up and more intensive to decreasing the morbidity and mortality rate of heart failure.To determine whether PREDICE score could predict mortality within 90 days in patients with heart failure, an observational cohort study in patients with heart failure who were hospitalized due to worsening chronic heart failure. Patients were in following-up for up to 90 days after initial evaluation with the primary endpoint is death.We found a difference of the significantstatistical between PREDICE score in survival and mortality group (p=0.001) of 84% (95% CI: 60.9% - 97.4%).In conclusion, PREDICE score has a good ability to predict mortality within 90 days in patients with heart failure.

Justifying Objective Bayesianism on Predicate Languages

Directory of Open Access Journals (Sweden)

Jürgen Landes

2015-04-01

Full Text Available Objective Bayesianism says that the strengths of one’s beliefs ought to be probabilities, calibrated to physical probabilities insofar as one has evidence of them, and otherwise sufficiently equivocal. These norms of belief are often explicated using the maximum entropy principle. In this paper we investigate the extent to which one can provide a unified justification of the objective Bayesian norms in the case in which the background language is a first-order predicate language, with a view to applying the resulting formalism to inductive logic. We show that the maximum entropy principle can be motivated largely in terms of minimising worst-case expected loss.

Metaphysical Modality, Modality of Predicate and the Theory of "Decisive Necessity”

Directory of Open Access Journals (Sweden)

L. Nabavi

2010-01-01

Full Text Available Aristotle in the Organon (1949: 9,30 a ,15-19 explicitly states that in a categorical syllogism when the minor premise is absolute (without modality operator and the major is necessary, the conclusion will be necessary too. This Aristotle's view has been the source of many conflicts and disputes in the history of logic. The famous logicians and historians of logic in the twentieth century as "Nicholas Rescher" and "Becker" believe that Aristotle's view is justifiable and defensible (at least compared to the first figure only if, the modality of major premise is considered as the property of predicate (modality de re. Today, we know very well that the modality of predicate is closely linked to Metaphysical and philosophical Modality. “Shihab al-Din al- Suhrawardi” in the theory of "Decisive (Battateh Necessity” by accepting this base, explicitly states that, in the beginning, the modality must be mentioned as a part of the predicate and then the modality of relation or copula is summarized and reduced to necessity. The modern formalization of the most important part of this theory is as follows: ("x (àAx É à Bx º ("x □ (àAx É à BxThis paper discusses the historical overview of the metaphysical modality firstly and then shows that the theory of "Decisive Necessity” is true and justified in a model of modal logic with equivalent accessibility relation and homogeneous possible world view (fixed domain.

Predicate Structures, Gesture, and Simultaneity in the Representation of Action in British Sign Language: Evidence From Deaf Children and Adults

Science.gov (United States)

Cormier, Kearsy

2013-01-01

British Sign Language (BSL) signers use a variety of structures, such as constructed action (CA), depicting constructions (DCs), or lexical verbs, to represent action and other verbal meanings. This study examines the use of these verbal predicate structures and their gestural counterparts, both separately and simultaneously, in narratives by deaf children with various levels of exposure to BSL (ages 5;1 to 7;5) and deaf adult native BSL signers. Results reveal that all groups used the same types of predicative structures, including children with minimal BSL exposure. However, adults used CA, DCs, and/or lexical signs simultaneously more frequently than children. These results suggest that simultaneous use of CA with lexical and depicting predicates is more complex than the use of these predicate structures alone and thus may take deaf children more time to master.

A. JALILA

2015-03-01

Full Text Available Formal specification-based testing has been used widely to assess potential faults or prove their absence in a given system at the earliest. This research work has proposed an automated fault-based testing framework to test the specification of the system using Object Constraint Language (OCL. Accordingly, the possible faults in OCL specification of the system has been anticipated by mutating its method based on OCL predicate-based fault classes. Then, test cases are generated using Genetic Algorithm with simulated annealing technique. In this paper, a novel OCL-predicate based fitness function is defined to evaluate the generated test data. Finally, this paper presents the experimental results, which indicate that the proposed methodology provides more test coverage with the reduced test suite and test run. This results in cost-effective software development so as to improve software quality.

It is based on the "State-Law" historical and philosophically founded (Westphalia, Bodin and Hobbes, phenomenologically (Schmitt’s Political Theology and normatively (Hans Kelsen’s Legal Positivism based. The rationale on the Sstate leading role suggests that State power must be complete to achieve its goals, which is given by normativity.

Reminių lietuvių kalbos pagrindinių sakinio dalių perteikimas norvegų kalboje. Norwegian Equivalents to Lithuanian Rhemic Subject and Predicate

Directory of Open Access Journals (Sweden)

Aurelija Griškevičienė

2008-01-01

Full Text Available In Norwegian, like in other analytical languages, the distribution of information in terms of Functional Sentence Perspective (FSP is heavily constrained by the grammatically defined word order, whereas the main means of expression of FSP in written Lithuanian is the word order, which is grammatically unrestricted thus enabling to convey the new information by any sentence part. The aim of this article is to summarise and classify expressions of Norwegian equivalents to the rhemic subject and predicate in the Lithuanian language. The analysis resorts for illustrations to the short story “Gyvenimas po klevu” by Granauskas and its translation into Norwegian.The analysis shows, one of the best ways to shift the rhemic from the usual position at the begin­ning of a sentence in the Norwegian language is by applying the passive voice. The subject can equally be made rhemic by the cleft, presentative construction, the reduplication of a sentence part. The subject rhemisation can happen by replacing it with other sentence parts of the same meaning. To retain the rhemic subject in translation, not only can a word order be reshuffled, but even an extra sentence added to convey new information.In Norwegian, the predicate has a strictly defined second position. Therefore, the rhemic predicate is impossible to indicate by a word order. In Norwegian sentences where new information is presented through the predicate, the position of the predicate is considered rhemic, and no other means to express the rhemic predicated are employed. In translation, the rhemic predicate can be expressed through the nominalization, which facilitates the needed shift. As the empiric material demonstrates, the predicate replacement by any other sentence part is the most frequent way for the rhemisation of the predicate. It is also possible to make verb-for-verb replacement. In certain cases, extra themic elements, helping to shift the focus predicate.The use of lexical means

Jiao, Pengfei; Cai, Fei; Feng, Yiding; Wang, Wenjun

Link predication aims at forecasting the latent or unobserved edges in the complex networks and has a wide range of applications in reality. Almost existing methods and models only take advantage of one class organization of the networks, which always lose important information hidden in other organizations of the network. In this paper, we propose a link predication framework which makes the best of the structure of networks in different level of organizations based on nonnegative matrix factorization, which is called NMF 3 here. We first map the observed network into another space by kernel functions, which could get the different order organizations. Then we combine the adjacency matrix of the network with one of other organizations, which makes us obtain the objective function of our framework for link predication based on the nonnegative matrix factorization. Third, we derive an iterative algorithm to optimize the objective function, which converges to a local optimum, and we propose a fast optimization strategy for large networks. Lastly, we test the proposed framework based on two kernel functions on a series of real world networks under different sizes of training set, and the experimental results show the feasibility, effectiveness, and competitiveness of the proposed framework.

2017-12-01

Full Text Available The purpose of the study is to identify the main reasons of money laundering in Bangladesh among the twenty seven predicate offences of money laundering prescribed by Bangladesh Bank and position of Bangladesh among South Asian Countries regarding anti-money laundering practices. Besides, an anti-money laundering model has been developed to combat against money laundering as 14 percent bankers think that only existing know your customer form and transaction profile of banking sector are not enough to detect money laundering. To conduct the study, 91 bankers have been surveyed to take response through structured questionnaire regarding their opinion about the predicate offences of money laundering and sufficiency of existing KYC form of banking sector to detect money laundering. From the responses, factor analysis, test of hypothesis, correlation and regression analysis have been conducted using SPSS software. The study identifies that predicate offences of money laundering can be minimized mainly through scrutinizing the activities of local criminals with foreign network and strict anti-corruption measures through automation in National Board of Revenue, strict policy adoption of criminal detection and support from foreign experts. Besides, regression model shows that only six predicate offences of money laundering explains 87.2 percent of money laundering that should get more emphasize to combat against money laundering. From the comparative analysis, it has been found that Bangladesh in holding better position just after India among six South Asian Countries according to Basel AML Index score. This study provides a complete understanding of the position of Bangladesh in case of money laundering and anti-money laundering practices. The integration of four domains, i.e. AML model development, factor analysis, econometric analysis and comparative analysis of AML index will provide insights to managers and policy makers about the money laundering

Kill the song—steal the show: what does distinguish predicative metaphors from decomposable idioms?

Science.gov (United States)

Caillies, Stéphanie; Declercq, Christelle

2011-06-01

This study examined the semantic processing difference between decomposable idioms and novel predicative metaphors. It was hypothesized that idiom comprehension results from the retrieval of a figurative meaning stored in memory, that metaphor comprehension requires a sense creation process and that this process difference affects the processing time of idiomatic and metaphoric expressions. In the first experiment, participants read sentences containing decomposable idioms, predicative metaphors or control expressions and performed a lexical decision task on figurative targets presented 0, 350, and 500 ms, or 750 after reading. Results demonstrated that idiomatic expressions were processed sooner than metaphoric ones. In the second experiment, participants were asked to assess the meaningfulness of idiomatic, metaphoric and literal expressions after reading a verb prime that belongs to the target phrase (identity priming). The results showed that verb identity priming was stronger for idiomatic expressions than for metaphor ones, indicating different mental representations.

2015-01-01

In this discussion we will concentrate on the main characteristics of an alternative kind of logic invented by Hans Götzsche: Occurrence Logic, which is not based on truth functionality. Our approach is based on temporal logic developed and elaborated by A. N. Prior. We will focus on characterising...... argumentation based on formal Occurrence Logic concerning events and occurrences, and illustrate the relations between Predicate Logic and Occurrence Logic. The relationships (and dependencies) is conducive to an approach that can analyse the occurrences of ”logical statements based on different logical...... principles” in different moments. We will also conclude that the elaborated Götzsche’s Occurrence Logic could be able to direct us to a truth-functional independent computer-based logic for analysing argumentation based on events and occurrences....

Social Interface Model: Theorizing Ecological Post-Delivery Processes for Intervention Effects.

Science.gov (United States)

Pettigrew, Jonathan; Segrott, Jeremy; Ray, Colter D; Littlecott, Hannah

2018-01-03

Successful prevention programs depend on a complex interplay among aspects of the intervention, the participant, the specific intervention setting, and the broader set of contexts with which a participant interacts. There is a need to theorize what happens as participants bring intervention ideas and behaviors into other life-contexts, and theory has not yet specified how social interactions about interventions may influence outcomes. To address this gap, we use an ecological perspective to develop the social interface model. This paper presents the key components of the model and its potential to aid the design and implementation of prevention interventions. The model is predicated on the idea that intervention message effectiveness depends not only on message aspects but also on the participants' adoption and adaptation of the message vis-à-vis their social ecology. The model depicts processes by which intervention messages are received and enacted by participants through social processes occurring within and between relevant microsystems. Mesosystem interfaces (negligible interface, transference, co-dependence, and interdependence) can facilitate or detract from intervention effects. The social interface model advances prevention science by theorizing that practitioners can create better quality interventions by planning for what occurs after interventions are delivered.

Attribute-Based Signcryption: Signer Privacy, Strong Unforgeability and IND-CCA Security in Adaptive-Predicates Model (Extended Version

Directory of Open Access Journals (Sweden)

Tapas Pandit

2016-08-01

Full Text Available Attribute-Based Signcryption (ABSC is a natural extension of Attribute-Based Encryption (ABE and Attribute-Based Signature (ABS, where one can have the message confidentiality and authenticity together. Since the signer privacy is captured in security of ABS, it is quite natural to expect that the signer privacy will also be preserved in ABSC. In this paper, first we propose an ABSC scheme which is weak existential unforgeable and IND-CCA secure in adaptive-predicates models and, achieves signer privacy. Then, by applying strongly unforgeable one-time signature (OTS, the above scheme is lifted to an ABSC scheme to attain strong existential unforgeability in adaptive-predicates model. Both the ABSC schemes are constructed on common setup, i.e the public parameters and key are same for both the encryption and signature modules. Our first construction is in the flavor of CtE&S paradigm, except one extra component that will be computed using both signature components and ciphertext components. The second proposed construction follows a new paradigm (extension of CtE&S , we call it “Commit then Encrypt and Sign then Sign” (CtE&S . The last signature is generated using a strong OTS scheme. Since, the non-repudiation is achieved by CtE&S paradigm, our systems also achieve the same.

Convex polyhedral abstractions, specialisation and property-based predicate splitting in Horn clause verification

DEFF Research Database (Denmark)

Kafle, Bishoksan; Gallagher, John Patrick

2014-01-01

We present an approach to constrained Horn clause (CHC) verification combining three techniques: abstract interpretation over a domain of convex polyhedra, specialisation of the constraints in CHCs using abstract interpretation of query-answer transformed clauses, and refinement by splitting...... in conjunction with specialisation for propagating constraints it can frequently solve challenging verification problems. This is a contribution in itself, but refinement is needed when it fails, and the question of how to refine convex polyhedral analyses has not been studied much. We present a refinement...... technique based on interpolants derived from a counterexample trace; these are used to drive a property-based specialisation that splits predicates, leading in turn to more precise convex polyhedral analyses. The process of specialisation, analysis and splitting can be repeated, in a manner similar...

Predicate Argument Structure Analysis for Use Case Description Modeling

Science.gov (United States)

Takeuchi, Hironori; Nakamura, Taiga; Yamaguchi, Takahira

In a large software system development project, many documents are prepared and updated frequently. In such a situation, support is needed for looking through these documents easily to identify inconsistencies and to maintain traceability. In this research, we focus on the requirements documents such as use cases and consider how to create models from the use case descriptions in unformatted text. In the model construction, we propose a few semantic constraints based on the features of the use cases and use them for a predicate argument structure analysis to assign semantic labels to actors and actions. With this approach, we show that we can assign semantic labels without enhancing any existing general lexical resources such as case frame dictionaries and design a less language-dependent model construction architecture. By using the constructed model, we consider a system for quality analysis of the use cases and automated test case generation to keep the traceability between document sets. We evaluated the reuse of the existing use cases and generated test case steps automatically with the proposed prototype system from real-world use cases in the development of a system using a packaged application. Based on the evaluation, we show how to construct models with high precision from English and Japanese use case data. Also, we could generate good test cases for about 90% of the real use cases through the manual improvement of the descriptions based on the feedback from the quality analysis system.

An Insider Threat Neutralization Mitigation Model Predicated On Cognitive Dissonance (ITNMCD

Directory of Open Access Journals (Sweden)

Keshnee Padayachee

2015-07-01

Full Text Available The insider threat concern is a complex issue, as the problem domain intersects the social, technical and socio-technical dimensions. Consequently, counteracting the insider threat involves influencing the insider’s perceptions and behaviour in order to ensure compliance. When an individual’s actions and beliefs are incongruent, this induces a phenomenon known as cognitive dissonance. In order to reduce this dissonance, individuals are self-motivated either to change their behaviours or beliefs, or to rationalize their behaviour. Neutralization is a technique used by criminals to rationalize maleficence. In terms of the insider threat, it has been proposed that if the justifications for committing an offence are eliminated, then the insider is less likely to commit the offence. This process is known as neutralization mitigation. The research reported on here proposes that inducing cognitive dissonance may be a means of mitigating the neutralizations that the insider may use to justify maleficence. To integrate these concepts into a pragmatic implementable solution the Insider Threat Neutralization Mitigation model predicated on Cognitive Dissonance (ITNMCD is proposed. A proof-of-concept was developed and the model concept was evaluated using the design science method.

Andreu Carminati

2017-07-01

Full Text Available Worst-case execution time (WCET is a parameter necessary to guarantee timing constraints on real-time systems. The higher the worst-case execution time of tasks, the higher will be the resource demand for the associated system. The goal of this paper is to propose a different way to perform loop unrolling on data-dependent loops using code predication targeting WCET reduction, because existing techniques only consider loops with fixed execution counts. We also combine our technique with existing unrolling approaches. Results showed that this combination can produce aggressive WCET reductions when compared with the original code.

Predication of skin temperature and thermal comfort under two-way transient environments.

Science.gov (United States)

Zhou, Xin; Xiong, Jing; Lian, Zhiwei

2017-12-01

In this study, three transient environmental conditions consisting of one high-temperature phase within two low-temperature phases were developed, thus creating a temperature rise followed by a temperature fall. Twenty-four subjects (including 12 males and 12 females) were recruited and they underwent all three test scenarios. Skin temperature on seven body parts were measured during the whole period of the experiment. Besides, thermal sensation was investigated at specific moments by questionnaires. Thermal sensation models including PMV model, Fiala model and the Chinese model were applied to predict subjects' thermal sensation with comparisons carried out among them. Results show that most predicated thermal sensation by Chinese model lies within the range of 0.5 scale of the observed sensation vote, and it agrees best with the observed thermal sensation in transient thermal environment than PMV and Fiala model. Further studies should be carried out to improve performance of Chinese model for temperature alterations between "very hot" to "hot" environment, for prediction error in the temperature-fall situation of C5 (37-32°C) was over 0.5 scale.

Nichols, Kim; Burgh, Gilbert; Kennedy, Callie

2017-02-01

Developing students' skills to pose and respond to questions and actively engage in inquiry behaviours enables students to problem solve and critically engage with learning and society. The aim of this study was to analyse the impact of providing teachers with an intervention in inquiry pedagogy alongside inquiry science curriculum in comparison to an intervention in non-inquiry pedagogy alongside inquiry science curriculum on student questioning and other inquiry behaviours. Teacher participants in the comparison condition received training in four inquiry-based science units and in collaborative strategic reading. The experimental group, the community of inquiry (COI) condition, received training in facilitating a COI in addition to training in the same four inquiry-based science units. This study involved 227 students and 18 teachers in 9 primary schools across Brisbane, Australia. The teachers were randomly allocated by school to one of the two conditions. The study followed the students across years 6 and 7 and students' discourse during small group activities was recorded, transcribed and coded for verbal inquiry behaviours. In the second year of the study, students in the COI condition demonstrated a significantly higher frequency of procedural and substantive higher-order thinking questions and other inquiry behaviours than those in the comparison condition. Implementing a COI within an inquiry science curriculum develops students' questioning and science inquiry behaviours and allows teachers to foster inquiry skills predicated by the Australian Science Curriculum. Provision of inquiry science curriculum resources alone is not sufficient to promote the questioning and other verbal inquiry behaviours predicated by the Australian Science Curriculum.

La Medicina Basada en la Evidencia: ¿mejoró la medicina que practicamos y enseñamos?

Directory of Open Access Journals (Sweden)

Luis Huicho

2013-07-01

Full Text Available En los últimos años la práctica y la enseñanza médica han incorporado en forma progresiva y creciente el concepto de medicina basada en la evidencia (MBE. La misma se define como la utilización de la mejor evidencia proveniente de la investigación clínica para la toma de decisiones en el manejo del paciente individual. Esta propuesta de cambio en la manera de practicar y enseñar la medicina clínica es, en parte, consecuencia del vertiginoso avance de la investigación científica, particularmente en las últimas décadas, aunque el costo creciente involucrado en la atención de los pacientes ha jugado también un rol importante en su desarrollo y consolidación. La MBE implica la integración de la preparación y experiencia del médico con la mejor evidencia clínica externa accesible, proveniente de la investigación sistemática, proporcionando una visión más crítica en la toma de decisiones clínicas, para ofrecer atención de calidad óptima al paciente, evitando errores en cada una de las diferentes etapas del proceso de diagnóstico y tratamiento. En ausencia de información recolectada sistemáticamente, no es fácil llegar a una conclusión sobre los efectos de la MBE en la práctica y la enseñanza de la medicina en nuestro medio. Sin duda contamos hoy con mayor evidencia científica, incluyendo aquella relacionada a los problemas de salud infantil, y también se ha producido un avance vertiginoso en la tecnología que nos permite acceder a dicha información en tiempo real, a la cabecera del paciente. Sin embargo, si deseamos de veras lograr una mejor medicina, basada en la ciencia y en el respeto a la salud como un derecho que nos asiste a todos, hay necesidad de romper definitivamente con el paradigma predominante de una medicina jerárquica, poco dada a la discusión y a la justificación de las decisiones clínicas, de aprovechar la mejora sustancial ocurrida en el acceso a la evidencia disponible, y de mostrar mayor

It is expected to make use of the knowledge that was extracted by analyzing the mistakes of the past to prevent recurrence of accidents. Currently main analytic style is an analytic style that experts decipher deeply the accident cases, but cross-analysis has come to an end with extracting the common factors in the accident cases. We propose an integrated analyzing method for progress events to analyze among accidents in this study. Our method realized the integration of many accident cases by the integration connecting the common keyword called as 'Subject' or 'Predicate' that are extracted from each progress event in accident cases or near-miss cases. Our method can analyze and visualize the partial risk identification and the frequency to cause accidents and the risk assessment from the data integrated accident cases.

To evaluate the feasibility of clinical application for genetic based dosing algorithm in the predication of warfarin maintenance dose in Chinese population. The clinical data were collected and blood samples harvested from a total of 126 patients undergoing heart valve replacement. The genotypes of VKORC1 and CYP2C9 were determined by melting curve analysis after PCR. They were divided randomly into the study and control groups. In the study group, the first three doses of warfarin were prescribed according to the predicted warfarin maintenance dose while warfarin was initiated at 2.5 mg/d in the control group. The warfarin doses were adjusted according to the measured international normalized ratio (INR) values. And all subjects were followed for 50 days after an initiation of warfarin therapy. At the end of a 50-day follow-up period, the proportions of the patients on a stable dose were 82.4% (42/51) and 62.5% (30/48) for the study and control groups respectively. The mean durations of reaching a stable dose of warfarin were (27.5 ± 1.8) and (34.7 ± 1.8) days and the median durations were (24.0 ± 1.7) and (33.0 ± 4.5) days in the study and control groups respectively. Significant differences existed in the durations of reaching a stable dose between the two groups (P = 0.012). Compared with the control group, the hazard ratio (HR) for the duration of reaching a stable dose was 1.786 in the study group (95%CI 1.088 - 2.875, P = 0.026). The predicted dosing algorithm incorporating genetic and non-genetic factors may shorten the duration of achieving efficiently a stable dose of warfarin. And the present study validates the feasibility of its clinical application.

Las marcas en atletismo se han venido considerando como una muestra de los límites físicos del hombre. Desde los inicios del atletismo moderno se planteó la cuestión de cuáles serían los posibles límites en la evolución de los resultados, y todas las propuestas se vieron rápidamente rebasadas. Sin embargo un estudio en profundidad de las marcas obtenidas en los últimos veinte años, no sólo por el mejor atleta de cada momento, sino por el conjunto de los atletas destacados, sugiere que en el caso de las pruebas masculinas se está llegando a una situación cercana a la estabilidad, cuando no al retroceso en determinadas especialidades. Las pruebas femeninas tienen en muchos casos todavía un largo recorrido, por ser de reciente implantación. En este trabajo se analizan las pruebas olímpicas, tanto masculinas como femeninas, en su evolución desde 1978, y se observa que en casi todos los casos se dibuja claramente una tendencia asintotica hacia unos límites ya cercanos.

This has allowed us to determine which of the previous tests is the best in predicting the behaviour of a real wall. In addition, the tests have also helped in defining a process to evaluate the moisture content of walls in a buildings, which is important for heritage restoration projects.Para un mejor conocimiento del comportamiento de las fábricas antiguas de ladrillo frente a la ascensión capilar de agua, se han realizado en laboratorio ensayos de absorción de agua, de contenido de humedad, de porosidad aparente, de temperatura e imágenes con cámara termográfica sobre muros de fábrica y sus materiales componentes: ladrillo y argamasa. Ello ha permitido inferir cuál es el ensayo realizado a los ladrillos que mejor predice el comportamiento del muro real. También ha permitido definir un procedimiento para evaluar el contenido de humedad de fábricas existentes, importante para los proyectos de restauración del patrimonio construido.

Serían los profesores Giovanni Iafrancesco y Arturo Luna, junto con Darío Galindo Toro, Zoólogo de la Universidad Nacional de Colombia, quienes nos iniciarían en las ciencias naturales y nos abrirían el mundo riguroso y formativo de las publicaciones científicas, dentro de las cuales por supuesto, primaba Caldasia. Recuerdo en particular haber cargado todo un semestre, fotocopiado como correspondía, anotado, manchado y arrugado hasta su destrucción final, el artículo de Henry von Prahl y Gustavo Manjarrés acerca de los “Cangrejos Gecarcínidos de Colombia” (#66 de 1984, fresquito para cuando ejercí de monitor del curso de invertebrados y descubrí que podía comprar cangrejos en las pescaderías del centro de Bogotá para hacer un excelente ejercicio de laboratorio, guiado por el texto clásico de Barnes y lo más reciente del inventario nacional del grupo, reportado en Caldasia. La revista fue la puerta a la Ciencia, con mayúsculas y la que además pondría los nombres de los especialistas colombianos, la mayoría del Instituto de Ciencias Naturales, si no del INDERENA, al alcance de muchas generaciones que no teníamos ni el acceso a las publicaciones indexadas ni la cultura de consultarlas y no encontrábamos en la oferta de otras bibliotecas, salvo escasas excepciones, referentes a la biodiversidad colombiana. En conjunto con la memoria y generosidad del “mono” Hernández, a quien todos conoceríamos en algún momento de nuestras vidas, Caldasia era la biblioteca disponible y el paradigma de la investigación, donde todos aspirábamos publicar alguna vez.

The baseline platelet count (BPC) in patients with acute ST elevation myocardial infarction (STEMI) may reflect the baseline anjiografic finding and may also predic long-term outcomes after primary percutaneous coronary intervention (PPCI). Available data for the value of BPC in patients with STEMI treated with PPCI are still questionable. Therefore, we sought to determine the prognostic value of BPC for baseline angiographic finding and the impact of BPC on clinical outcomes of patients treating with PPCI. Blood sample for BPC was obtained on admission in 140 consecutive patients undergoing PPCI. Patients were divided 2 groups that group-1 (104 patients): TIMI flow-grade 0 and group-2 (36 patients): TIMI flow-grade 1-3. Follow-up was performed at 1-9 months. Baseline demographics were comparable, but, BPC was significantly higher in group-1 comparing 2 (293.7±59.8x10(9)/L vs. 237.7±50.9x10(9)/L, pmeasuring of a BPC on admission may also provide further practical and therapeutic profits.

2016-01-01

Health disparities are seen in many chronic conditions including asthma. Young African American adults represent a population at high risk for poor asthma outcomes due to both their minority status and the difficult transition from adolescence to adulthood. Recruitment and retention has been challenging in this demographic stratum, and traditional asthma education is often not feasible. The objective of this study was to develop and assess the feasibility of an electronic asthma self-management program for young African American adults. A total of 44 African American adults (age 18-30 years) with uncontrolled persistent asthma were enrolled in an asthma self-management program. The 6-week Breathe Michigan program (predicated on the social cognitive theory) was tailored specifically to the concerns and preferences of young African American adults. The entire program was completed electronically, without any specialized human support. At 2 weeks and 3 months after program completion, participants were contacted for follow-up. A total of 89% of enrolled subjects completed the 6-week intervention, and 77% were available for evaluation at 3 months. All subjects completing the 2-week postprogram survey reported that the program was helpful, and 97% would recommend it to others. Asthma control as measured by the Asthma Control Test improved from 16.1 to 19.3 (P young African American adults. Copyright © 2015 American Academy of Allergy, Asthma & Immunology.

Highlights: • Lower heating values of neat biodiesel and its blends were measured experimentally. • Lower heating value prediction models were developed based on the density and viscosity values of the fuel. • The predication models were validated by measured values and previous models. • The prediction models were used to predict the lower heating value of 24 biodiesel feedstock types produced globally. • The effects of lower heating vale on brake specific fuel consumption and thermal efficiency were investigated. - Abstract: The heating value of fuel is one of its most important physical properties, and is used for the design and numerical simulation of combustion processes within internal combustion (IC) engines. Recently, there has been a significant increase in the use of dual fuel and blended fuels in compression ignition (CI) engines. Most of the blended fuels include biodiesel as one of the constituents and hence the objective of this study is to investigate the effect of biodiesel content to lower heating value (LHV) and to develop new LHV prediction models that correlate the LHV with biodiesel fraction, density and viscosity. Furthermore, this study also investigated the effects of the LHV on CI engines performance parameters experimentally. To achieve the above mentioned objectives density, viscosity and LHV of rapeseed oil biodiesel, corn oil biodiesel and waste oil biodiesel at different blend fraction values (B0, B5, B10, B20, B50, B75, and B100, where ‘B5’ denotes a blend of 5% biodiesel and 95% mineral diesel, etc.) were measured as per EN ISO 3675:1998, EN ISO 3104:1996 and DIN 51900 standards. The engine experimental work was conducted on a four-cylinder, four-stroke, direct injection (DI) and turbocharged diesel engine by using rapeseed oil and normal diesel blends. Based on the experimental results, models were developed which have the capability to predict the LHV corresponding to different fractions, densities and viscosities of

Pediatric interventional radiology (PIR) comprises a range of minimally invasive diagnostic and therapeutic procedures that are performed using image guidance. PIR has emerged as an essential adjunct to various surgical and medical conditions. Over the years, technology has undergone dramatic and continuous evolution, making this speciality grow. In this review, the authors will discuss various vascular interventional procedures undertaken in pediatric patients. It is challenging for the interventional radiologist to accomplish a successful interventional procedure. There are many vascular interventional radiology procedures which are being performed and have changed the way the diseases are managed. Some of the procedures are life saving and have become the treatment of choice in those patients. The future is indeed bright for the practice and practitioners of pediatric vascular and non-vascular interventions. As more and more of the procedures that are currently being performed in adults get gradually adapted for use in the pediatric population, it may be possible to perform safe and successful interventions in many of the pediatric vascular lesions that are otherwise being referred for surgery.

Full Text Available Objetivo: Mediante la adaptación a Colombia del modelo realizado por BresMed y previo análisis de transferibilidad, se realizó un análisis de costo-efectividad del tratamiento de denervación renal vs. mejor tratamiento estándar en el control de la hipertensión resistente y los eventos cardiovasculares relacionados. Métodos: Se construyó un modelo de Markov con 32 estados de salud y siete resultados finales: accidente cerebrovascular, infarto del miocardio, enfermedad coronaria, falla cardiaca, enfermedad renal crónica terminal, mortalidad cardiovascular y muerte. Se consideró un horizonte de toda la vida, la perspectiva desde el pagador y una tasa de descuento del 3%. Para el cálculo de las probabilidades de sufrir eventos se utilizaron las ecuaciones de riesgo de Framingham y las efectividades se tomaron del estudio clínico SYMPLICITY HTN-2. Los costos se extrajeron del entorno local y las tasas de mortalidad del Observatorio global de salud de la Organización Mundial de la Salud. Los resultados incluyeron los costos de cada alternativa de tratamiento, así como los años de vida ajustados a calidad ganados. Se realizaron análisis determinístico y probabilístico. Resultados: El tratamiento de denervación renal produjo 12,48 años de vida ajustados a calidad ganados a un costo de US $46.509 vs. 11,68 años de vida ajustados a calidad ganados del mejor tratamiento estándar a un costo de US $41.199, con un costo incremental por años de vida ajustados a calidad ganados de US $6.612. Tanto el análisis de sensibilidad univariado como el probabilístico, mostraron la robustez de los resultados. Conclusiones: El tratamiento de denervación renal, con un costo incremental por años de vida ajustados a calidad ganados de $6.612, muy por debajo de 1 PIB per cápita de Colombia, mostró ser altamente costo-efectivo.

First-generation college students (students for whom neither parent has a 4-year college degree) earn lower grades and worry more about whether they belong in college, compared with continuing-generation students (who have at least 1 parent with a 4-year college degree). We conducted a longitudinal follow-up of participants from a study in which a values-affirmation intervention improved performance in a biology course for first-generation college students, and found that the treatment effect on grades persisted 3 years later. First-generation students in the treatment condition obtained a GPA that was, on average, .18 points higher than first-generation students in the control condition, 3 years after values affirmation was implemented (Study 1A). We explored mechanisms by testing whether the values-affirmation effects were predicated on first-generation students reflecting on interdependent values (thus affirming their values that are consistent with working-class culture) or independent values (thus affirming their values that are consistent with the culture of higher education). We found that when first-generation students wrote about their independence, they obtained higher grades (both in the semester in which values affirmation was implemented and in subsequent semesters) and felt less concerned about their background. In a separate laboratory experiment (Study 2) we manipulated the extent to which participants wrote about independence and found that encouraging first-generation students to write more about their independence improved their performance on a math test. These studies highlight the potential of having FG students focus on their own independence. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Critical point predication device

An operation for predicting a critical point by using a existent reverse multiplication method has been complicated, and an effective multiplication factor could not be plotted directly to degrade the accuracy for the prediction. The present invention comprises a detector counting memory section for memorizing the counting sent from a power detector which monitors the reactor power, a reverse multiplication factor calculation section for calculating the reverse multiplication factor based on initial countings and current countings of the power detector, and a critical point prediction section for predicting the criticality by the reverse multiplication method relative to effective multiplication factors corresponding to the state of the reactor core previously determined depending on the cases. In addition, a reactor core characteristic calculation section is added for analyzing an effective multiplication factor depending on the state of the reactor core. Then, if the margin up to the criticality is reduced to lower than a predetermined value during critical operation, an alarm is generated to stop the critical operation when generation of a period of more than a predetermined value predicted by succeeding critical operation. With such procedures, forecasting for the critical point can be easily predicted upon critical operation to greatly mitigate an operator's burden and improve handling for the operation. (N.H.)

Mindfulness interventions aim to foster greater attention to and awareness of present moment experience. There has been a dramatic increase in randomized controlled trials (RCTs) of mindfulness interventions over the past two decades. This article evaluates the growing evidence of mindfulness intervention RCTs by reviewing and discussing (a) the effects of mindfulness interventions on health, cognitive, affective, and interpersonal outcomes; (b) evidence-based applications of mindfulness interventions to new settings and populations (e.g., the workplace, military, schools); (c) psychological and neurobiological mechanisms of mindfulness interventions; (d) mindfulness intervention dosing considerations; and (e) potential risks of mindfulness interventions. Methodologically rigorous RCTs have demonstrated that mindfulness interventions improve outcomes in multiple domains (e.g., chronic pain, depression relapse, addiction). Discussion focuses on opportunities and challenges for mindfulness intervention research and on community applications.

Las prácticas de enseñanza declaradas de los “mejores profesores” de la Universidad de Vigo. [The declared teaching practices of the “best teachers” at the University of Vigo

Full Text Available The present article intends to identify, make visible, describe, and explain the teaching practices that the best teachers of the University of Vigo declare to carry out. To do so, the authors have developed a process of research that includes qualitative interviews. Before stating the main conclusions of our research, we wish to explain that the concern of this work was not to do an evaluation of the teaching practices, good or bad, of the University of Vigo professors, but to look for models of good teaching practices. The main conclusion is that, even among the best teachers, the majority of current teaching practices could be classified as the traditional model of teaching in which the teacher and content play a central role. This fact shouldn’t be surprising, nor should it cause us to diminish the importance of studying and making visible the teaching practices of good teachers, even if they are less innovative, as this is the best way to stimulate all teachers to improve their teaching practices.El objetivo del presente trabajo consiste en identificar, hacer visibles, describir y explicar las prácticas de enseñanza que declaran realizar los “mejores profesores” de la Universidad de Vigo. Para ello, planteamos un diseño cualitativo a través de la técnica de la entrevista. Antes de hacer mención de las principales conclusiones hemos de hacer constar que nos interesaba buscar referencias de “buenas prácticas”, no hacer una evaluación de las prácticas docentes, buenas o malas, del profesorado de la Universidad de Vigo. La principal conclusión es que incluso entre los “mejores profesores” predominan unas prácticas docentes que podrían encuadrarse, mayoritariamente, en el enfoque “tradicional de la enseñanza”, centrada en el profesor/contenido. No debería sorprender el hecho, ni tampoco llevarnos a relativizar el interés de la visibilización de las “buenas prácticas docentes” aunque estas sean poco

La muestra estaba formada por 43 adolescentes con edades entre 12 y 18 años con diagnóstico de diabetes desde hace más de un año. Como medidas psicosociales se utilizó una Escala de adhesión al tratamiento, una Escala de afrontamiento, una Escala de apoyo social (elaboradas para este trabajo y una Escala de estrés (traducida y adaptada de Kohn y Milrose. El control metabólico se registró a través de la hemoglobina glucolizada. Se recurrió al análisis de regresión múltiple para identificar las variables que mejor explican los resultados de salud. Los resultados indican que la adhesión a la dieta y la monitorización se predicen a partir del afrontamiento emocional y del afrontamiento instrumental; la adhesión al ejercicio es predicha por la edad, por el estrés asociado al futuro personal y por el apoyo social médico; y la adhesión a la insulina es predicha por el afrontamiento emocional. Además, se encontró que el control metabólico se predice a partir de la adhesión al ejercicio físico. Estos resultados sugieren que las intervenciones con adolescentes diabéticos deben considerar algunas variables psicociales de cara a promover mejores resultados en salud.

La tablet para el aprendizaje de vocabulario en segundas lenguas: teclado, lápiz digital u opción múltiple

2017-01-01

Full Text Available Las tecnologías móviles están aumentando su presencia en las aulas. Mientras estas tecnologías ofrecen oportunidades para facilitar el aprendizaje, entre ellas la adquisición de una segunda lengua (L2, su potencial sigue sin aprovecharse plenamente. Aunque las aplicaciones de las tablets permiten la escritura y tareas similares a las que pueden hacerse en papel, siguen ofreciendo mayoritariamente ejercicios de selección múltiple o de relleno de huecos. Este cambio en medio y modalidad de práctica podría significar un impacto en el aprendizaje de una segunda lengua. Basada en la perspectiva de la cognición incorporada, nuestra hipótesis predice que el hecho de escribir se traduce en un mejor proceso de memorización y una mejor ortografía frente a la mecanografía o al uso de ejercicios de opción múltiple. Esta hipótesis ha sido comprobada en un estudio cuasi-experimental basado en el aula: alumnos (N=282 que practicaron vocabulario de francés a través de tres modalidades de práctica: ejercicios de opción múltiple, escritura con un teclado y escritura a mano alzada. Aunque se haya encontrado que las tres modalidades de práctica apoyaron al proceso de aprendizaje, los resultados demostraron que los alumnos que practicaron el vocabulario escribiendo con lápiz o con la tablet obtuvieron puntuaciones más altas en ortografía y dominio de signos diacríticos comparados con los alumnos que realizaron ejercicios de selección múltiple. Pasar más tiempo aprendiendo vocabulario a un nivel más alto de procesamiento conduce a una mayor adquisición de vocabulario.

The obesity epidemic has spread to young adults, and obesity is a significant risk factor for cardiovascular disease. The prominence and increasing functionality of mobile phones may provide an opportunity to deliver longitudinal and scalable weight management interventions in young adults. The aim of this article is to describe the design and development of the intervention tested in the Cell Phone Intervention for You study and to highlight the importance of adaptive intervention design that made it possible. The Cell Phone Intervention for You study was a National Heart, Lung, and Blood Institute-sponsored, controlled, 24-month randomized clinical trial comparing two active interventions to a usual-care control group. Participants were 365 overweight or obese (body mass index≥25 kg/m2) young adults. Both active interventions were designed based on social cognitive theory and incorporated techniques for behavioral self-management and motivational enhancement. Initial intervention development occurred during a 1-year formative phase utilizing focus groups and iterative, participatory design. During the intervention testing, adaptive intervention design, where an intervention is updated or extended throughout a trial while assuring the delivery of exactly the same intervention to each cohort, was employed. The adaptive intervention design strategy distributed technical work and allowed introduction of novel components in phases intended to help promote and sustain participant engagement. Adaptive intervention design was made possible by exploiting the mobile phone's remote data capabilities so that adoption of particular application components could be continuously monitored and components subsequently added or updated remotely. The cell phone intervention was delivered almost entirely via cell phone and was always-present, proactive, and interactive-providing passive and active reminders, frequent opportunities for knowledge dissemination, and multiple tools

Workplaces are a good setting for interventions that aim to support workers in achieving a healthier diet and body weight. However, little is known about the factors that impact on the feasibility and implementation of these interventions, and how these might vary by type of workplace and type of worker. The aim of this study was to explore the views of those involved in commissioning and delivering the Better Health at Work Award, an established and evidence-based workplace health improvement programme. One-to-one semi-structured interviews were conducted with 11 individuals in North East England who had some level of responsibility for delivering workplace dietary interventions. Interviews were transcribed verbatim and analysed using thematic framework analysis. A number of factors were felt to promote the feasibility and implementation of interventions. These included interventions that were cost-neutral (to employee and employer), unstructured, involved colleagues for support, took place at lunchtimes, and were well-advertised and communicated via a variety of media. Offering incentives, not necessarily monetary, was perceived to increase recruitment rates. Factors that militate against feasibility and implementation of interventions included worksites that were large in size and remote, working patterns including shifts and working outside of normal working hours that were not conducive to workers being able to access intervention sessions, workplaces without appropriate provision for healthy food on site, and a lack of support from management. Intervention deliverers perceived that workplace dietary interventions should be equally and easily accessible (in terms of cost and timing of sessions) for all staff, regardless of their job role. Additional effort should be taken to ensure those staff working outside normal working hours, and those working off-site, can easily engage with any intervention, to avoid the risk of intervention-generated inequalities (IGIs).

Syntaxe de l'adverbe de phrase et structure prédicative de la proposition allemande : Eléments pour une description fonctionnelle

2016-07-01

Full Text Available The syntax of higher-order adverbials (modal and argumentative adverbials, among others raises several challenges for the topological model of German sentence structure when it comes to its semantic and/or information structural interpretation. It is often assumed that, when used in post-verbal position, in the so-called middle field of the sentence, or in a subordinate clause, they mark the border between a topical or thematic field (defined as « what the proposition is about » and the comment or rheme (« what is said about the topic/theme ». More specifically, researchers such as FOURQUET and ZEMB have given a predicational reading of this theme-rheme opposition; the placement of higher-order adverbials and/or sentence negation is supposed to be the index of the border between the main predicate (corresponding to the « right middle field » and its domain of validity (« left middle field ». Yet, on the basis of authentic data, it appears that the crucial requirement for this claim, namely that there is one and only one slot for such « phematic » adverbials in each proposition, does not fit with reality. More specifically, higher-order adverbials can be realized inside the allegedly thematic part of the middle field. The article proposes to use a framework derived from DIK's Functional Grammar to solve this problem. According to this approach, the proposition is generated through a succession of predications corresponding to a precise number of representational levels. I argue that constituent order in German exhibits some regularities corresponding to this view. Once this finite series of predications is taken for granted, ZEMB's model can be reformulated in such a way that there is a slot for higher-order adverbials at each predicational level. This claim matches the semantic intuitions of both FOURQUET and ZEMB, and the data observed in corpora. Finally, I propose that higher-order adverbials be treated as commending both the domain

El sistema de Seguridad Social es una responsabilidad compartida y es importante que los trabajadores bajo su protección se comprometan adoptando estilos de vida saludable y aprovechando todas las oportunidades que la sociedad les brinda para mantenerse activos. Es por ello que, además de la promoción de la salud de los trabajadores y de la prevención de los riesgos laborales, un sistema proactivo y preventivo de gestión de las EEPP, implica actuaciones que apoyen si es posible, la reincorporación al trabajo de los trabajadores afectos de estas patologías.

Full Text Available Congenital adrenal hyperplasia (CAH due to 21-hydroxylase deficiency is a disorder which can adopt three clinical expressions: two classical forms -salt-wasting (SW, with residual enzymatic activity (EA La hiperplasia suprarrenal congénita por déficit de 21-hidroxilasa presenta tres formas clínicas: dos clásicas, perdedora de sal, con actividad enzimática (AE < 1% y virilizante simple, con AE 1-2% y una no clásica, con AE 10-60%. Nuestro objetivo es describir las características clínicas y el genotipo de un grupo de pacientes con hiperplasia suprarrenal congénita; este último también se determinó en todos los miembros de la familia. Se estudiaron 9 pacientes diagnosticados en la etapa perinatal y 8 durante la etapa pre y postpuberal. Se analizaron diez mutaciones en el gen CYP21A2 y se evaluó crecimiento y densidad mineral ósea. Once pacientes presentaron la forma clásica: 9 con diagnóstico perinatal y 2 diagnosticados más tardíamente, uno de ellos con agrandamiento testicular por restos adrenales. Todos los pacientes, salvo 1 con una mutación de novo R356W en un alelo, presentaron ambos alelos mutados con un genotipo que predice AE < 2%. Seis pacientes presentaron la forma no clásica, todos con signos clínicos de hiperandrogenismo salvo un familiar asintomático que se diagnosticó por el estudio molecular. Todos, a excepción de uno con un alelo aún no determinado, presentaron la mutación V281L acompañada de otra que predice AE < 2%. Durante la evolución de los pacientes de diagnóstico perinatal se observó talla baja al año con recuperación de la misma en la etapa prepuberal. La densidad mineral ósea fue normal. Podemos concluir que el diagnóstico en la etapa perinatal en pacientes con la forma clásica posibilita un mejor seguimiento y crecimiento. La genotipificación de todos los miembros de una familia permite el diagnóstico de formas asintomáticas. La presencia de mutaciones de novo y de un alelo con una

Verum focus and polar questions

Full Text Available We argue that some word order phenomena in Romanian and Sardinian are the result of a checking operation in the left periphery involving verum focus (i.e. focus on the polarity component of the sentence. In particular, this operation accounts for some word order patterns found in polar questions. In Romanian, polarity fronting is realized as head-movement of (V+T to a higher peripheral head which bears a Focus-probe. This licenses VS orders for predications in which VS is not allowed as a neutral order (i-level predicates, iteratives, generics. In Sardinian, an entire phrase headed by the lexical predicate (verbal non-finite form or non-verbal predicate is fronted before the auxiliary. We argue that this order is obtained by two movement operations, head-raising of Aux to Foc and movement of the predicate phrase to SpecFoc. We also present the semantics of polarity focus, distinguishing several types of focus (informational, emphatic, contrastive.

The Use of Intervention Mapping to Develop a Tailored Web-Based Intervention, Condom-HIM.

Many HIV (human immunodeficiency virus) prevention interventions are currently being implemented and evaluated, with little information published on their development. A framework highlighting the method of development of an intervention can be used by others wanting to replicate interventions or develop similar interventions to suit other contexts and settings. It provides researchers with a comprehensive development process of the intervention. The objective of this paper was to describe how a systematic approach, intervention mapping, was used to develop a tailored Web-based intervention to increase condom use among HIV-positive men who have sex with men. The intervention was developed in consultation with a multidisciplinary team composed of academic researchers, community members, Web designers, and the target population. Intervention mapping involved a systematic process of 6 steps: (1) needs assessment; (2) identification of proximal intervention objectives; (3) selection of theory-based intervention methods and practical strategies; (4) development of intervention components and materials; (5) adoption, implementation, and maintenance; and (6) evaluation planning. The application of intervention mapping resulted in the development of a tailored Web-based intervention for HIV-positive men who have sex with men, called Condom-HIM. Using intervention mapping as a systematic process to develop interventions is a feasible approach that specifically integrates the use of theory and empirical findings. Outlining the process used to develop a particular intervention provides clarification on the conceptual use of experimental interventions in addition to potentially identifying reasons for intervention failures. ©Joyal Miranda, José Côté.

Physical therapist interventions, such as those designed to change physical activity behavior, are often complex and multifaceted. In order to facilitate rigorous evaluation and implementation of these complex interventions into clinical practice, the development process must be comprehensive, systematic, and transparent, with a sound theoretical basis. Intervention Mapping is designed to guide an iterative and problem-focused approach to the development of complex interventions. The purpose of this case report is to demonstrate the application of an Intervention Mapping approach to the development of a complex physical therapist intervention, a remote self-management program aimed at increasing physical activity after acquired brain injury. Intervention Mapping consists of 6 steps to guide the development of complex interventions: (1) needs assessment; (2) identification of outcomes, performance objectives, and change objectives; (3) selection of theory-based intervention methods and practical applications; (4) organization of methods and applications into an intervention program; (5) creation of an implementation plan; and (6) generation of an evaluation plan. The rationale and detailed description of this process are presented using an example of the development of a novel and complex physical therapist intervention, myMoves-a program designed to help individuals with an acquired brain injury to change their physical activity behavior. The Intervention Mapping framework may be useful in the development of complex physical therapist interventions, ensuring the development is comprehensive, systematic, and thorough, with a sound theoretical basis. This process facilitates translation into clinical practice and allows for greater confidence and transparency when the program efficacy is investigated. © 2016 American Physical Therapy Association.

Full Text Available Aunque la educación ha constituido siempre un componente esencial de la profesión médica, su desarrollo explícito y específico sólo se ha iniciado en las últimas décadas. La investigación en educación médica está todavía en una etapa muy inicial de su desarrollo. Las intervenciones educativas son habitualmente complejas y de carácter cualitativo; resulta, por ello, difícil, aunque indispensable, obtener evidencias científicas que avalen tanto los diversos métodos educativos utilizados como los instrumentos de evaluación que se emplean en los diferentes niveles de la formación médica. A partir de la perspectiva y de las estrategias generadas por las metodologías de la medicina basada en la evidencia, ha surgido recientemente la Colaboración EMBE como una red internacional que tiene como objetivo prioritario recoger y promover el despliegue de la mejor evidencia de la cual se pueda disponer sobre el rigor y la calidad de los actuales y de los nuevos métodos educativos y evaluativos en el ámbito de la profesión médica, a fin de optimizar el uso de la extraordinaria inversión que realiza la sociedad en la formación de los profesionales en atención médica.

Malaysia is experiencing a nutrition transition with burgeoning obesity, particularly in women, and a growing prevalence of non-communicable disease. These health burdens have severe implications not only for adult health but also across generations. Pre-conception health promotion could address the intergenerational risk of metabolic disease. This paper describes the development of the "Jom Mama" intervention using Intervention Mapping (IM). The Jom Mama intervention aims to improve the health of young adult couples in Malaysia prior to conception. IM comprises of five steps prior to the last one, which involves the evaluation of the intervention. We used the five steps to develop the Jom Mama intervention. Both the process and evidence is documented providing the rationale to the selection of the key objectives of the intervention: (i) increasing healthy dietary practice; (ii) increasing physical activity levels, (iii) reducing sedentary activity; and (iv) improving social support to offset stressful lifestyles. From the IM process, Jom Mama will be health-system centred approach that uniquely combines both community health promoters and an electronic-health platform to deliver the complex intervention. IM is an iterative process that systematically gathers "best" evidence, selects appropriate theories of behaviour change, and facilitates formative research so as to develop a complex intervention. Though the IM process is time consuming, complex, and costly, it has enriched the Jom Mama intervention with a number of notable advantages: (i) intervention fashioned on formative work with stakeholders and in the target group; (ii) intervention combines research evidence with theory; (iii) intervention acknowledges multiple dynamics of influence; and (iv) intervention is embedded within health service priorities in Malaysia for greater scale-up possibility.

Radiological interventions possess wide utilization in the diagnosis and treatment for pediatric patients. Pediatric interventional radiology is an important branch of interventional radiology and also an important branch of pediatric radiology. Pediatric interventional radiology has grown substantially over the last 30 years, radiologists closely cooperation with surgeons and other physicians providing a new horizon in the management of pediatric diseases in western countries. It includes pediatric cardiac interventional radiology, pediatric neuro-interventional radiology, pediatric vascular interventional radiology, pediatric nonvascular interventional radiology, pediatric tumor interventional radiology and others. In the United States, every children hospital which owns two hundred beds has to have special trained interventional radiologists in radiologic department installing with advanced digital subtraction angiographic equipment. Interventional therapeutic procedures and diagnostic angiography have been proceeding more and more for the congenital and acquired diseases of children. The promising results give use uprising and interventional therapy as an alternative or a replacement or supplement to surgical operation. Pediatric interventional radiology is rather underdeveloped in China with a few special pediatric interventional radiologist, lack of digital subtraction angiography equipment. Pediatric radiologists have no enough field for interventional procedures such as pediatric neuro-interventional radiology and pediatric vascular interventional radiology. In the contrary adult interventional radiologists do have better interventional jobs in China and Pediatric cardiologists also share the same trend. They perform angiocardiography for congenital heart diseases and treat congenital heart disease with interventional procedures including balloon dilation of valves and vessels, coil embolization of collaterals, patent ducts and other arterial fistulae

Persistent new HIV infections and risky behaviors underscore the need for enhanced HIV prevention. Social media interventions may promote safe sexual behaviors, increase HIV testing uptake, and promote safe injection behaviors. This review discusses how social media interventions tap into the wisdom of crowds through crowdsourcing, build peer-mentored communities, and deliver interventions through social networks. Social media HIV prevention interventions are constrained by ethical issues, low social media usage among some key populations, and implementation issues. Comprehensive measurement of social media interventions to prevent HIV is necessary, but requires further development of metrics.

The past decades have witnessed interventional radiology in China to go from a very initial clinical practice to an important medical player in modern medicine. Recently, a friendly collaboration has been successfully established between the Chinese Interventional Radiology Sub-society and the Journal of Interventional Radiology. The Chinese Interventional Radiology Sub-society will take the full responsibility for the academic governance of the Journal of Interventional Radiology and the Journal of Interventional Radiology will formally become the sole interventional academic periodical of the Chinese Interventional Radiology Sub-society in China. This collaboration will surely make Chinese interventional radiology to initiate a new era,promote the further development of interventional radiology at home and enable the Journal of Interventional Radiology to step into the international medical circle.

Dalum, Peter; Schaalma, Herman; Kok, Gerjo

2012-02-01

The objective of this project was to develop a theory- and evidence-based adolescent smoking cessation intervention using both new and existing materials. We used the Intervention Mapping framework for planning health promotion programmes. Based on a needs assessment, we identified important and changeable determinants of cessation behaviour, specified change objectives for the intervention programme, selected theoretical change methods for accomplishing intervention objectives and finally operationalized change methods into practical intervention strategies. We found that guided practice, modelling, self-monitoring, coping planning, consciousness raising, dramatic relief and decisional balance were suitable methods for adolescent smoking cessation. We selected behavioural journalism, guided practice and Motivational Interviewing as strategies in our intervention. Intervention Mapping helped us to develop as systematic adolescent smoking cessation intervention with a clear link between behavioural goals, theoretical methods, practical strategies and materials and with a strong focus on implementation and recruitment. This paper does not present evaluation data.

Web-based interventions in nursing.

Im, Eun-Ok; Chang, Sun Ju

2013-02-01

With recent advances in computer and Internet technologies and high funding priority on technological aspects of nursing research, researchers at the field level began to develop, use, and test various types of Web-based interventions. Despite high potential impacts of Web-based interventions, little is still known about Web-based interventions in nursing. In this article, to identify strengths and weaknesses of Web-based nursing interventions, a literature review was conducted using multiple databases with combined keywords of "online," "Internet" or "Web," "intervention," and "nursing." A total of 95 articles were retrieved through the databases and sorted by research topics. These articles were then analyzed to identify strengths and weaknesses of Web-based interventions in nursing. A strength of the Web-based interventions was their coverage of various content areas. In addition, many of them were theory-driven. They had advantages in their flexibility and comfort. They could provide consistency in interventions and require less cost in the intervention implementation. However, Web-based intervention studies had selected participants. They lacked controllability and had high dropouts. They required technical expertise and high development costs. Based on these findings, directions for future Web-based intervention research were provided.

Application of a Patient Derived Xenograft Model for Predicative Study of Uterine Fibroid Disease.

Directory of Open Access Journals (Sweden)

Martin Fritsch

Full Text Available Human uterine fibroids, benign tumors derived from the smooth muscle layers of the uterus, impose a major health burden to up to 50% of premenopausal women in their daily life. To improve our understanding of this disease, we developed and characterized a patient-derived xenograft model by subcutaneous transplantation of pieces of human uterine fibroid tissue into three different strains of severe combined immunodeficient mice. Engrafted uterine fibroid tissue preserved the classical morphology with interwoven bundles of smooth muscle cells and an abundant deposition of collagenous matrix, similar to uterine fibroids in situ. The grafts expressed both estrogen receptor 1 and progesterone receptor. Additionally, both receptors were up-regulated by estrogen treatment. Growth of the fibroid grafts was dependent on 17β-estradiol and progesterone supplementation at levels similar to women with the disease and was studied for up to 60 days at maximum. Co-treatment with the antiprogestin mifepristone reduced graft growth (four independent donors, p<0.0001 two-sided t-test, as did treatment with the mTOR inhibitor rapamycin (three independent donors, p<0.0001 two-sided t-test. This in vivo animal model preserves the main histological and functional characteristics of human uterine fibroids, is amenable to intervention by pharmacological treatment, and can thus serve as an adequate model for the development of novel therapies.

Analysis of Foreign Exchange Interventions by Intervention Agent with an Artificial Market Approach

Science.gov (United States)

Matsui, Hiroki; Tojo, Satoshi

We propose a multi-agent system which learns intervention policies and evaluates the effect of interventions in an artificial foreign exchange market. Izumi et al. had presented a system called AGEDASI TOF to simulate artificial market, together with a support system for the government to decide foreign exchange policies. However, the system needed to fix the amount of governmental intervention prior to the simulation, and was not realistic. In addition, the interventions in the system did not affect supply and demand of currencies; thus we could not discuss the effect of intervention correctly. First, we improve the system so as to make much of the weights of influential factors. Thereafter, we introduce an intervention agent that has the role of the central bank to stabilize the market. We could show that the agent learned the effective intervention policies through the reinforcement learning, and that the exchange rate converged to a certain extent in the expected range. We could also estimate the amount of intervention, showing the efficacy of signaling. In this model, in order to investigate the aliasing of the perception of the intervention agent, we introduced a pseudo-agent who was supposed to be able to observe all the behaviors of dealer agents; with this super-agent, we discussed the adequate granularity for a market state description.

Intervention-engagement and its role in the effectiveness of stage-matched interventions promoting physical exercise.

Richert, Jana; Lippke, Sonia; Ziegelmann, Jochen P

2011-01-01

Intervention-engagement has received little attention in sports medicine as well as research and promotion of physical exercise. The construct is important, however, in the understanding of why interventions work. This study aimed at shedding more light on the interplay of engagement and the subsequent effectiveness of physical exercise interventions. A three-stage model differentiating among nonintenders, intenders, and actors informed the intervention design in this study. In an Internet-based randomized controlled trial (RCT) with two measurement points, N = 326 participants received a stage-matched, stage-mismatched, or control treatment. Assessed variables were goal setting, planning, behavior, and intervention-engagement. It was found that regarding goal setting, nonintenders in the stage-matched intervention and those who engaged highly in the stage-matched intervention improved significantly over time. Regarding planning, intenders in the matched condition as well as all actors increased their levels over time. Regarding behavior, nonintenders and intenders having engaged highly in the intervention improved more than those having engaged little. In order to help nonintenders progress on their way toward goal behavior, it is necessary that they engage highly in a stage-matched intervention. Implications for exercise promotion are that interventions should also aim at increasing participants' intervention-engagement.

To assess the potential of laughter and humour interventions to increase well-being in a general population of adults aged 60 plus; and to develop a classification to compare approaches and potential benefits of different intervention types. A systematic search of Web of Science, PubMed/MEDLINE, PsychInfo, AMED, and PsychArticles used inclusive terms relating to laughter and humour interventions. A realist synthesis approach enabled heterogeneous interventions to be compared pragmatically. Five laughter interventions, and one humour intervention, using one or more outcome related to well-being, were considered for inclusion after screening 178 primary research papers. The five laughter interventions, representing a sample of 369 participants, were retained. Well-being related outcome measures reported in each intervention informed efficacy; Joanna Briggs Institute tools appraised design; and a realist approach enabled heterogeneous interventions to be measured on their overall potential to provide an evidence base. Well-being related measures demonstrated at least one significant positive effect in all interventions. Confounding factors inherent in the intervention types were observed. Individual participant laughter was not reported. Laughter and humour interventions appear to enhance well-being. There is insufficient evidence for the potential of laughter itself to increase well-being as interventions contained a range of confounding factors and did not measure participant laughter. Interventions that isolate, track, and measure the parameters of individual laughter are recommended to build evidence for these potentially attractive and low-risk interventions. The classification proposed may guide the development of both evidence-oriented and population-appropriate intervention designs. Crown Copyright © 2018. Published by Elsevier Ltd.

Opportunity of interventional radiology: advantages and application of interventional technique in biological target therapy

International Nuclear Information System (INIS)

Teng Gaojun; Lu Qin

2007-01-01

Interventional techniques not only provide opportunity of treatment for many diseases, but also alter the traditional therapeutic pattern. With the new century of wide application of biological therapies, interventional technique also shows extensive roles. The current biological therapy, including gene therapy, cell transplantation therapy, immunobiologic molecule therapy containing cell factors, tumor antibody or vaccine, recombined proteins, radioactive-particles and targeting materials therapy, can be locally administrated by interventional techniques. The combination of targeting biological therapies and high-targeted interventional technique holds advantages of minimal invasion, accurate delivery, vigorous local effect, and less systemic adverse reactions. Authors believe that the biological therapy may arise a great opportunity for interventional radiology, therefore interventional colleagues should grasp firmly and promptly for the development and extension in this field.

Interventional studies in nuclear medicine

Saha, G.B.; Swanson, D.P.; Hladik, W.B. III

Pharmacological interventions in nuclear medicine studies have been in practice for a long time. The triiodothyronine (T/sub 3/) suppression, Thyroid-stimulating hormone (TSH) stimulation, and perchlorate discharge tests are common examples of well-established diagnostic interventional studies. In recent years, pharmacologic and physiologic interventions in other nuclear medicine procedures have drawn considerable attention. The primary purpose of these interventions is to augment, complement or, more often, differentiate the information obtained from conventional nuclear medicine diagnostic studies. Pharmacologic interventions involve the administration of a specific drug before, during, or after the administration of radiopharmaceutical for a given study. The change in information due to intervention of the drug offers clues to differentiating various disease conditions. These changes can be brought about by physiologic interventions also, e.g., exercise in radionuclide ventriculography. In the latter interventions, the physiologic function of an organ is enhanced or decreased by physical maneuvers, and the changes observed can be used to differentiate various disease conditions

2017-10-01

The aim of this study was to maximise the benefits from clinical trials involving technological interventions such as radiation therapy. High compliance to the quality assurance protocols is crucial. We assessed whether the quality of radiation therapy intervention was evaluated in Cochrane systematic reviews. We searched 416 published Cochrane systematic reviews and identified 67 Cochrane systematic reviews that investigated radiation therapy or radiotherapy as an intervention. For each systematic review, either quality assurance or quality control for the intervention was identified by a description of such processes in the published systematic reviews. Of the 67 Cochrane systematic reviews studied, only two mentioned quality assurance or quality control. Our findings revealed that 65 of 67 (97%) Cochrane systematic reviews of radiation therapy interventions failed to consider the quality of the intervention. We suggest that advice about the evaluation of intervention quality be added to author support materials. © 2017 The Royal Australian and New Zealand College of Radiologists.

The workplace is an ideal setting for health promotion. Helping employees to be more physically active can not only improve their physical and mental health, but can also have economic benefits such as reduced sickness absence. The current paper describes the development of a three month theory-based intervention that aims to increase levels of moderate intensity physical activity amongst employees in sedentary occupations. The intervention was developed using an intervention mapping protocol. The intervention was also informed by previous literature, qualitative focus groups, an expert steering group, and feedback from key contacts within a range of organisations. The intervention was designed to target awareness (e.g. provision of information), motivation (e.g. goal setting, social support) and environment (e.g. management support) and to address behavioural (e.g. increasing moderate physical activity in work) and interpersonal outcomes (e.g. encourage colleagues to be more physically active). The intervention can be implemented by local facilitators without the requirement for a large investment of resources. A facilitator manual was developed which listed step by step instructions on how to implement each component along with a suggested timetable. Although time consuming, intervention mapping was found to be a useful tool for developing a theory based intervention. The length of this process has implications for the way in which funding bodies allow for the development of interventions as part of their funding policy. The intervention will be evaluated in a cluster randomised trial involving 1350 employees from 5 different organisations, results available September 2009.

Purpose  Scope and clinical importance of interventional radiology markedly evolved over the last decades. Consequently it was acknowledged as independent subspecialty by the "European Union of Medical Specialists" (UEMS). Based on radiological imaging techniques Interventional Radiology is an integral part of Radiology. Materials und Methods  In 2009 the German Society for Interventional Radiology and minimally-invasive therapy (DeGIR) developed a structured training in Interventional Radiology. In cooperation with the German Society of Neuroradiology (DGNR) this training was extended to also cover Interventional Neuroradiology in 2012. Tailored for this training in Interventional Radiology a structured curriculum was developed, covering the scope of this modular training. Results  The curriculum is based on the DeGIR/DGNR modular training concept in Interventional Radiology. There is also an European Curriculum and Syllabus for Interventional Radiology developed by the "Cardiovascular and Interventional Radiological Society of Europe" (CIRSE). The presented curriculum in Interventional Radiology is designed to provide a uniform base for the training in Interventional Radiology in Germany, based on the competencies obtained during residency. Conclusion  This curriculum can be used as a basis for training in Interventional Radiology by all training sites. Key Points: · Interventional Radiology is an integral part of clinical radiology. · The German Society for Interventional Radiology and minimally-invasive therapy (DeGIR) developed a curriculum in Interventional Radiology. · This curriculum is an integrative basis for the training in interventional.

This article describes the development of the social network-based intervention Powerful Together with Diabetes which aims to improve diabetes self-management (DSM) among patients with type 2 diabetes living in socioeconomically deprived neighborhoods by stimulating social support for DSM and diminishing social influences hindering DSM (e.g., peer pressure and social norms). The intervention was specifically developed for patients with Dutch, Turkish, Moroccan, and Surinamese backgrounds. The intervention was developed according to Intervention Mapping. This article describes the first four steps of Intervention Mapping: (1) the needs assessment; (2) development of performance and change objectives; (3) selection of theory-based methods and strategies; and (4) the translation of these into an organized program. These four steps resulted in Powerful Together with Diabetes , a 10-month group-based intervention consisting of 24 meetings, 6 meetings for significant others, and 2 meetings for participants and their spouses. The IM method resulted in a tailored approach with a specific focus on the social networks of its participants. This article concludes that the IM method helped our planning team to tailor the intervention to the needs of our target population and facilitated our evaluation design. However, in hindsight, the intervention could have been improved by investing more in participatory planning and community involvement.

The prevalence of childhood obesity has increased during the past decades and is now considered an urgent public health problem. Although stabilizing trends in obesity prevalence have been identified in parts of Europe, preventive efforts in children are still needed. Using the socio-ecological approach as the underlying theoretical perspective, the IDEFICS project aimed to develop, implement and evaluate a community-based intervention for the prevention of childhood obesity in eight European countries. The aim of the present manuscript was to describe the content and developmental process of the IDEFICS intervention. The intervention mapping protocol (IMP) was used to develop the community-based intervention for the prevention of childhood obesity in 3 to 10 years old children. It is a theory- and evidence-based tool for the structured planning and development of health promotion programs that requires the completion of six different steps. These steps were elaborated by two coordinating centers and discussed with the other participating centers until agreement was reached. Focus group research was performed in all participating centers to provide an informed basis for intervention development. The application of the IMP resulted in an overall intervention framework with ten intervention modules targeting environmental and personal factors through the family, the school and the community. The summary results of the focus group research were used to inform the development of the overall intervention. The cultural adaptation of the overall intervention was realised by using country specific focus group results. The need for cultural adaptation was considered during the entire process to improve program adoption and implementation. A plan was developed to evaluate program effectiveness and quality of implementation. The IDEFICS project developed a community-based intervention for the prevention of childhood obesity by using to the intervention mapping heuristic. The

Full Text Available La respuesta al tratamiento psicológico para el Trastorno Obsesivo-Compulsivo (TOC es variable, y las tasas de abandono y recaída son preocupantes. Mientras los estudios que analizan la reducción de los síntomas son favorables, los resultados son menos alentadores cuando estos se definen en términos de cambio clínicamente significativo. Existe poco conocimiento de lo que predice el resultado del tratamiento. Este estudio examinó predictores demográficos, sintomáticos y cognitivos de los resultados en 79 participantes en terapia cognitivo-conductual individualizada para el TOC. Después de investigar las diferencias entre los que completaron el tratamiento y no lo finalizaron, se analizó la respuesta al tratamiento según la definición de gravedad post-tratamiento de los síntomas y el cambio clínicamente fiable, así como predictores de la respuesta al tratamiento. Los que completaron el tratamiento eran menos propensos a presentar comorbilidad. Baja intensidad de síntomas en el pre-tratamiento y mayor perfeccionismo/intolerancia a la incertidumbre fueron los mejores predictores de los resultados. Los cambios en las creencias obsesivas se asociaron con el cambio sintomático, aunque sólo perfeccionismo/intolerancia a la incertidumbre fue predictor del cambio posttratamiento.

Full Text Available Abstract Background Frailty is a term commonly used to describe the condition of an older person who has chronic health problems, has lost functional abilities and is likely to deteriorate further. However, despite its common use, only a small number of studies have attempted to define the syndrome of frailty and measure its prevalence. The criteria Fried and colleagues used to define the frailty syndrome will be used in this study (i.e. weight loss, fatigue, decreased grip strength, slow gait speed, and low physical activity. Previous studies have shown that clinical outcomes for frail older people can be improved using multi-factorial interventions such as comprehensive geriatric assessment, and single interventions such as exercise programs or nutritional supplementation, but no interventions have been developed to specifically reverse the syndrome of frailty. We have developed a multidisciplinary intervention that specifically targets frailty as defined by Fried et al. We aim to establish the effects of this intervention on frailty, mobility, hospitalisation and institutionalisation in frail older people. Methods and Design A single centre randomised controlled trial comparing a multidisciplinary intervention with usual care. The intervention will target identified characteristics of frailty, functional limitations, nutritional status, falls risk, psychological issues and management of chronic health conditions. Two hundred and thirty people aged 70 and over who meet the Fried definition of frailty will be recruited from clients of the aged care service of a metropolitan hospital. Participants will be followed for a 12-month period. Discussion This research is an important step in the examination of specifically targeted frailty interventions. This project will assess whether an intervention specifically targeting frailty can be implemented, and whether it is effective when compared to usual care. If successful, the study will establish a

To assess the role of Intervention Mapping (IM) in designing disease prevention interventions worldwide. Systematic search and review of the relevant literature-peer-reviewed and grey-was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Only five of the twenty two included studies reviewed were RCTs that compared intervention using IM protocol with placebo intervention, and provided the outcomes in terms of percentage increase in the uptake of disease-prevention programmes, and only one of the five studies provided an effect measure in the form of relative risk (RR = 1.59, 95% CI = 1.08-2.34, p = 0.02). Of the five RCTs, three were rated as strong evidences, one as a medium evidence and one as a weak evidence, and they all reported statistically significant difference between the two study groups, with disease prevention interventions that have used the intervention mapping approach generally reported significant increases in the uptake of disease-prevention interventions, ranging from 9% to 28.5% (0.0001 ≤ p ≤ 0.02), On the other hand, all the 22 studies have successfully identified the determinants of the uptake of disease prevention interventions that is essential to the success of disease prevention programmes. Intervention Mapping has been successfully used to plan, implement and evaluate interventions that showed significant increase in uptake of disease prevention programmes. This study has provided a good understanding of the role of intervention mapping in designing disease prevention interventions, and a good foundation upon which subsequent reviews can be guided.

Positive Psychological Interventions for Patients with Type 2 Diabetes: Rationale, Theoretical Model, and Intervention Development

Full Text Available Most patients with type 2 diabetes (T2D have suboptimal adherence to recommended diet, physical activity, and/or medication. Current approaches to improve health behaviors in T2D have been variably effective, and successful interventions are often complex and intensive. It is therefore vital to develop interventions that are simple, well-accepted, and applicable to a wide range of patients who suffer from T2D. One approach may be to boost positive psychological states, such as positive affect or optimism, as these constructs have been prospectively and independently linked to improvements in health behaviors. Positive psychology (PP interventions, which utilize systematic exercises to increase optimism, well-being, and positive affect, consistently increase positive states and are easily delivered to patients with chronic illnesses. However, to our knowledge, PP interventions have not been formally tested in T2D. In this paper, we review a theoretical model for the use of PP interventions to target health behaviors in T2D, describe the structure and content of a PP intervention for T2D patients, and describe baseline data from a single-arm proof-of-concept (N=15 intervention study in T2D patients with or without depression. We also discuss how PP interventions could be combined with motivational interviewing (MI interventions to provide a blended psychological-behavioral approach.

Few interventions to promote physical activity (PA) adapt dynamically to changes in individuals' behavior. Interventions targeting determinants of behavior are linked with increased effectiveness and should reflect changes in behavior over time. This article describes the application of two frameworks to assist the development of an adaptive evidence-based smartphone-delivered intervention aimed at influencing PA and sedentary behaviors (SB). Intervention mapping was used to identify the determinants influencing uptake of PA and optimal behavior change techniques (BCTs). Behavioral intervention technology was used to translate and operationalize the BCTs and its modes of delivery. The intervention was based on the integrated behavior change model, focused on nine determinants, consisted of 33 BCTs, and included three main components: (1) automated capture of daily PA and SB via an existing smartphone application, (2) classification of the individual into an activity profile according to their PA and SB, and (3) behavior change content delivery in a dynamic fashion via a proof-of-concept application. This article illustrates how two complementary frameworks can be used to guide the development of a mobile health behavior change program. This approach can guide the development of future mHealth programs.

Cardiovascular diseases are the first cause of death in Spain. The most usual procedures in interventional cardiology are coronariography and PTCA. The first is a diagnostic technique, and the second one is interventional. Our goal has been to study procedures made during the first six months in the Interventional Cardiology Unit of the Juan Ramon Jimenez Hospital (Huelva-Spain), taking into account radiation protection issues. We have studied 178 patients; 145 of them underwent coronariography, and 33 of the patients had PTCA too. Every case was analyzed taking into account technical and dosimetric parameters. We show parameters values gathered: Diagnostic techniques (valvular and non-valvular patients), and interventional techniques (coronariography and PTCA in different or in the same intervention). Higher doses were obtained with valvular patients, although the number of frames was similar. Attending to therapeutic procedures, the highest values were gotten with the 'double' interventions. Interventional procedures exceed in 60% doses gotten in diagnostic studies: this is because of the number of series and number of frames per series. Similar values obtained by other authors have been gotten. (author)

The purpose of this study was to apply the Intervention Mapping approach as a framework in the development of a worksite intervention to improve the work ability of construction workers. Development of an intervention by using the Intervention Mapping approach. Construction worksite. Construction workers aged 45 years and older. According to the principles of Intervention Mapping, evidence from the literature was combined with data collected from stakeholders (e.g., construction workers, managers, providers). The Intervention Mapping approach resulted in an intervention with the following components: (1) two individual visits of a physical therapist to lower the physical workload, (2) a Rest-Break tool to improve the balance between work and recovery, and (3) two empowerment training sessions to increase the range of influence at the worksite. Application of Intervention Mapping in the development of a worksite prevention program was useful in the construction industry to obtain a positive attitude and commitment. Stakeholders could give input regarding the program components as well as provide specific leads for the practical intervention strategy. Moreover, it also gives insight in the current theoretical and empirical knowledge in the field of improving the work ability of older workers in the construction industry.

Family intervention for schizophrenia.

It has been showed that people with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of their emotions. Psychosocial interventions designed to reduce these levels of expressed emotions within families now exist for mental health workers. These interventions are proposed as adjuncts rather than alternatives to drug treatments, and their main purpose is to decrease the stress within the family and also the rate of relapse. To estimate the effects of family psychosocial interventions in community settings for the care of those with schizophrenia or schizophrenia-like conditions compared to standard care. Electronic searches of the Cochrane Library (Issue 2, 1998), the Cochrane Schizophrenia Group's Register (June 1998), EMBASE (1981-1995) and MEDLINE (1966-1995) were undertaken and supplemented with reference searching of the identified literature. Randomised or quasi-randomised studies were selected if they focused on families of people with schizophrenia or schizoaffective disorder and compared community-orientated family-based psychosocial intervention of more than five sessions to standard care. Data were reliably extracted, and, where appropriate and possible, summated. Peto odds ratios (OR), their 95% confidence intervals (CI) and number needed to treat (NNT) were estimated. The reviewers assume that people who died or dropped out had no improvement and tested the sensitivity of the final results to this assumption. Family intervention may decrease the frequency of relapse (one year OR 0.57 CI 0.4-0.8, NNT 6.5 CI 4-14). The trend over time of this main finding is towards the null and some small but negative studies may not have been identified by the search. Family intervention may decrease hospitalisation and encourage compliance with medication but data are few and equivocal. Family intervention does not

Individuals with serious mental illness have high rates of obesity and a need for specialized weight loss intervention programs. This study examines the efficacy of the RENEW weight loss intervention and examines the impact of the intervention setting on outcomes. 136 individuals with serious mental illness from 4 different settings were randomly assigned to receive the RENEW weight loss intervention or a control condition of treatment as usual. The RENEW intervention is a one year program that includes an intensive, maintenance and intermittent supports phase. The intervention group experienced a modest weight loss of 4.8 lbs at 3 months, 4.1 lbs at 6 months and a slight weight gain of 1.5 lbs at 12 months. The control group gained a total of 6.2 lbs at 12 months. However when settings were examined separately the responder sites had a weight loss of 9.4 lbs at 3 months, 10.9 lbs at 6 months and 7 lbs at 12 months. These results suggest that the settings in which individuals receive services may act as a support or hindrance toward response to weight loss interventions. The concept of the obesogenic environment deserves further examination as a factor in the success of weight loss programs. Copyright © 2014 Elsevier B.V. All rights reserved.

Intervention principles: Theory and practice

After the Chernobyl accident, it became clear that some clarification of the basic principles for intervention was necessary as well as more internationally recognised numerical guidance on intervention levels. There was in the former USSR and in Europe much confusion over, and lack of recognition of, the very different origins and purposes of dose limits for controlling deliberate increases in radiation exposure for practices and dose levels at which intervention is prompted to decrease existing radiation exposure. In the latest recommendations from ICRP in its Publication 60, a clear distinction is made between the radiation protection systems for a practice and for intervention. According to ICRP, the protective measures forming a program of intervention, which always have some disadvantages, should each be justified on their own merit in the sense that they should do more good than harm, and their form, scale, and duration should be optimised so as to do the most good. Intervention levels for protective actions can be established for many possible accident scenarios. For planning and preparedness purposes, a generic optimisation based on generic accident scenario calculations, should result in optimised generic intervention levels for each protective measure. The factors entering such an optimisation will on the benefit side include avertable doses and avertable risks as well as reassurance. On the harm side the factors include monetary costs, collective and individual risk for the action itself, social disruption and anxiety. More precise optimisation analyses based on real site and accident specific data can be carried out and result in specific intervention levels. It is desirable that values for easily measurable quantities such as dose rate and surface contamination density be developed as surrogates for intervention levels of avertable dose. However, it is important that these quantities should be used carefully and applied taking account of local

en día en Colombia y cuáles son las perspectivas para una mejor utilización de este instrumento financiero que algunos autores consideran como un símbolo de los mercados financieros modernos.Colombia has to have a financial market that fits the needs of its increasingly internationalized economy. That means that a financial derivate market has to be developed. This includes a very deep options market in which forex options be widely dealt with in order to take advantage of the multiple benefits of this instrument specially for hedging purposes since the currency exchange risk is more and more threatening in a globalized world. Options are not very well known in Colombia and there is little information about them. They are only treaded in the over the counter (OTC market since there not exists an organized one. Of course, it is possible to contract tailor made options in the OTC market, which would not be the case in an organized market, but at the same time this implies more counterpart risk. Since the Colombian economy is getting more and more globalize and after adopting a floating exchange rate, the COP has experienced some appreciation that has risen up to 25%. This means considerable losses to the export sector. And also it should drive towards a culture more active in risk managing to hedge against foreign exchange volatility, which could avoid significant losses to the import/export sectors in the future. However, it has been identified that, in spite of the recent volatility of the peso/dollar exchange rate, there is little advance in developing such a culture. So this article focuses on the investigation done about the reasons why the mayor Colombian import/export companies had not progressed in forex hedging even though there is an increasing risk because of the mentioned volatility. Investigations carried out on those topics above said were complemented with the study of the variables that determine the market price of options allowed to conclude about

Exploring Environment-Intervention Fit: A Study of a Work Environment Intervention Program for the Care Sector

Targeting occupational health and safety interventions to different groups of employees and sectors is important. The aim of this study was to explore the environment-intervention fit of a Danish psychosocial work environment intervention program for the residential and home care sector. Focus group interviews with employees and interviews with mangers were conducted at 12 selected workplaces and a questionnaire survey was conducted with managers at all 115 workplaces. The interventions enhanced the probability of employees experiencing more “good” work days, where they could make a difference to the lives of clients. The interventions may therefore be characterized as culturally compelling and having a good fit with the immediate work environment of employees. The interventions furthermore seemed to fit well with the wider organizational environment and with recent changes in the societal and economic context of workplaces. However, some workplaces had difficulties with involving all employees and adapting the interventions to the organization of work. The findings suggest that flexibility and a variety of strategies to involve all employees are important aspects, if interventions are to fit well with the care sector. The focus on employees' conceptualization of a “good” work day may be useful for intervention research in other sectors. PMID:26380356

Reducing reliance on motorised transport and increasing use of more physically active modes of travel may offer an opportunity to address physical inactivity. This review evaluates the evidence for the effects of behavioural interventions to reduce car use for journeys made by adults and codes intervention development and content. The review follows the procedure stated in the registration protocol published in the PROSPERO database (registration number CRD42011001797). Controlled studies evaluating behavioural interventions to reduce car use compared with no interventions or alternative interventions on outcome measures of transport behaviours taken in adult participants are included in this review. Searches were conducted on all records in Applied Social Sciences Index and Abstracts (ASSIA), Ovid Embase, Ovid Medline, Ovid PsycInfo, Scopus, Sociological Abstracts, Transportation Research Information Service (TRIS), Transportation Research International Documentation (TRID), and Web of Science databases. Peer reviewed publications in English language meeting the inclusion criteria are eligible. Methodological quality is assessed using the Cochrane Risk of Bias Tool. Interventions are categorised in terms of behavioural frameworks, theories and techniques. 15 full text articles are included, representing 13 unique studies, with 4895 participants and 27 intervention arms. Risk of bias across the review is appraised as considerable due to the unclear methodological quality of individual studies. Heterogeneity of included studies is considerable. Meta-analyses reveal no significant effect on reduction of frequency of car use or on increasing the proportion of journeys by alternative, more active modes of transport. There is insufficient data relating to alternative outcomes such as distance and duration which may have important health implications. Interventions were top-down but could not be described as theory-based. Intervention efficacy was associated with the use

Quantifying the UK's incentives for low carbon investment

Wordsworth, Andrew; Grubb, Michael

2003-01-01

The UK climate change programme has introduced a range of instruments to foster investment in low carbon technologies and markets. We estimate the total value of these interventions, in terms of the redirection of financial flows and directly foregone tax income, to be about 1.3 billion pounds per year (Euro or US$: 2 billion per year), as from 2002 to 2003 when the renewable obligation certificates (ROCs) first take effect. About 20% of this consists of direct expenditure, the remaining 80% is in the form of indirect expenditures contained within sectors (ROCs, the energy efficiency commitments), and foregone tax revenues. Most of the energy-efficiency investment is estimated to recoup expenditure within normal life-cycles and may thus be considered profitable; the profitability of the supply-side interventions is predicated mostly upon expected cost reductions associated with the build up of the associated industries

Contextually and culturally congruent interventions are urgently needed to reduce racial, ethnic, and socioeconomic inequities in physical activity and cardiovascular disease. To examine a community-based participatory research (CBPR) process that incorporated storytelling into a physical activity intervention, and consider implications for reducing health inequities. We used a CBPR process to incorporate storytelling in an existing walking group intervention. Stories conveyed social support and problem-solving intervention themes designed to maintain increases in physical activity over time, and were adapted to the walking group context, group dynamics, challenges, and traditions. After describing of the CBPR process used to adapt stories to walking group sites, we discuss challenges and lessons learned regarding the adaptation and implementation of stories to convey key intervention themes. A CBPR approach to incorporating storytelling to convey intervention themes offers an innovative and flexible strategy to promote health toward the elimination of health inequities.

Author shows the weaknesses and difficulties of consequentialistic and deontological justification of humanitarian intervention. He points to the impossibility of a coherent moral theory of humanitarian intervention and argues that the humanitarian interventions of the nineties of the 20th century do not compliance just war. In his opinion, they represent an attempt of the quasi moral masking the real politics which lead the most powerful states in order to protect their national interests. .

Constructing a Theory- and Evidence-Based Treatment Rationale for Complex eHealth Interventions: Development of an Online Alcohol Intervention Using an Intervention Mapping Approach.

Due to limited reporting of intervention rationale, little is known about what distinguishes a good intervention from a poor one. To support improved design, there is a need for comprehensive reports on novel and complex theory-based interventions. Specifically, the emerging trend of just-in-time tailoring of content in response to change in target behavior or emotional state is promising. The objective of this study was to give a systematic and comprehensive description of the treatment rationale of an online alcohol intervention called Balance. We used the intervention mapping protocol to describe the treatment rationale of Balance. The intervention targets at-risk drinking, and it is delivered by email, mobile phone text messaging, and tailored interactive webpages combining text, pictures, and prerecorded audio. The rationale of the current treatment was derived from a self-regulation perspective, and the overarching idea was to support continued self-regulation throughout the behavior change process. Maintaining the change efforts over time and coping adaptively during critical moments (eg, immediately before and after a lapse) are key factors to successful behavior change. Important elements of the treatment rationale to achieving these elements were: (1) emotion regulation as an inoculation strategy against self-regulation failure, (2) avoiding lapses by adaptive coping, and (3) avoiding relapse by resuming the change efforts after a lapse. Two distinct and complementary delivery strategies were used, including a day-to-day tunnel approach in combination with just-in-time therapy. The tunnel strategy was in accordance with the need for continuous self-regulation and it functions as a platform from which just-in-time therapy was launched. Just-in-time therapy was used to support coping during critical moments, and started when the client reports either low self-efficacy or that they were drinking above target levels. The descriptions of the treatment

A coronagraph for operational space weather predication

2017-09-01

Accurate prediction of the arrival of solar wind phenomena, in particular coronal mass ejections (CMEs), at Earth, and possibly elsewhere in the heliosphere, is becoming increasingly important given our ever-increasing reliance on technology. The potentially severe impact on human technological systems of such phenomena is termed space weather. A coronagraph is arguably the instrument that provides the earliest definitive evidence of CME eruption; from a vantage point on or near the Sun-Earth line, a coronagraph can provide near-definitive identification of an Earth-bound CME. Currently, prediction of CME arrival is critically dependent on ageing science coronagraphs whose design and operation were not optimized for space weather services. We describe the early stages of the conceptual design of SCOPE (the Solar Coronagraph for OPErations), optimized to support operational space weather services.

Full Text Available En este trabajo se analiza la relación entre algunos factores de contingencia, el nivel de uso del cuadro de mando integral (CMI y el beneficio percibido gracias a su aplicación. El CMI es una herramienta capaz de ofrecer a los responsables de las organizaciones una visión completa de cómo a través de la integración de medidas financieras y no financieras se ejecuta la estrategia. Del análisis realizado sobre la base de los datos obtenidos de las sedes centrales de 61 empresas españolas de productos y servicios se deduce que el grado de formalización y estandarización en las empresas tiene una influencia directa y positiva en el desarrollo del CMI hacia niveles más integradores y orientados al valor añadido. Sin embargo, en relación con la influencia de otros factores examinados en esta investigación no se ha encontrado asociación significativa con un mayor desarrollo del CMI en las empresas españolas. Estos resultados contribuyen a complementar los presentados en trabajos previos (Braam y Nijssen, 2011; Cavalluzzo e Ittner, 2004. El documento también señala que el nivel de desarrollo del CMI se asocia con una mejor aplicación de los indicadores para evaluar actividades y mejorar el proceso decisorio. Finalmente, se plantean un conjunto de implicaciones relevantes para la gestión de las empresas.

Dental caries in young children is a major public health problem impacting on the child and their family in terms of pain, infection and substantial financial burden on healthcare funders. In the UK, national guidance on the prevention of dental caries advises parents to supervise their child's brushing with fluoride toothpaste until age 7. However, there is a dearth of evidence-based interventions to encourage this practice in parents. The current study used intervention mapping (IM) to develop a home-based parental-supervised toothbrushing intervention to reduce dental caries in young children. The intervention was developed using the six key stages of the IM protocol: (1) needs assessment, including a systematic review, qualitative interviews, and meetings with a multi-disciplinary intervention development group; (2) identification of outcomes and change objectives following identification of the barriers to parental-supervised toothbrushing (PSB), mapped alongside psychological determinants outlined in the Theoretical Domains Framework (TDF); (3) selection of methods and practical strategies; (4) production of a programme plan; (5) adoption and implementation and (6) Evaluation. The comprehensive needs assessment highlighted key barriers to PSB, such as knowledge, skills, self-efficacy, routine setting and behaviour regulation and underlined the importance of individual, social and structural influences. Parenting skills (routine setting and the ability to manage the behaviour of a reluctant child) were emphasised as critical to the success of PSB. The multi-disciplinary intervention development group highlighted the need for both universal and targeted programmes, which could be implemented within current provision. Two intervention pathways were developed: a lower cost universal pathway utilising an existing national programme and an intensive targeted programme delivered via existing parenting programmes. A training manual was created to accompany each

Functional improvement in bipolar and schizophrenic patients is one of the main aims of treatment. Nevertheless, there is no evidence about the effect of socio-occupational intervention within a multimodal intervention (MI) programme. To describe the socio-occupational profile and to evaluate the functional effect of a MI in bipolar I and schizophrenic patients. A prospective, longitudinal, therapeutic-comparative study was performed including 302 subjects (104 schizophrenic and 198 Bipolar Disorder I [BDI] patients), who were randomised into two groups, multimodal (psychiatry, psychology, medicine, occupational therapy, neuropsychology, and family therapy), or traditional intervention (psychiatry and medicine only). Several scales were applied to assess assertiveness, free time management, social abilities, general anxiety, self-care and performance in home, work and community tasks. After performing the longitudinal analysis, it was shown that the multimodal intervention was more effective than traditional intervention in general anxiety scores (P=.026) and development in home tasks (P=.03) in schizophrenic patients. No statistical differences were found in bipolar patients. The other variables showed improvement, however, their effect was similar in both intervention groups. Our study identified functional improvement in home tasks in schizophrenic patients after receiving multimodal intervention. Other variables also showed improvement for both interventions groups. Future studies, applying longer rehabilitation programs and other ecological strategies should be performed to identify the most effective interventions.

Although lifestyle interventions have shown to be effective in reducing the risk for type 2 diabetes mellitus, maintenance of achieved results is difficult, as participants often experience relapse after the intervention has ended. This paper describes the systematic development of a maintenance programme for the extensive SLIMMER intervention, an existing diabetes prevention intervention for high-risk individuals, implemented in a real-life setting in the Netherlands. The maintenance programme was developed using the Intervention Mapping protocol. Programme development was informed by a literature study supplemented by various focus group discussions and feedback from implementers of the extensive SLIMMER intervention. The maintenance programme was designed to sustain a healthy diet and physical activity pattern by targeting knowledge, attitudes, subjective norms and perceived behavioural control of the SLIMMER participants. Practical applications were clustered into nine programme components, including sports clinics at local sports clubs, a concluding meeting with the physiotherapist and dietician, and a return session with the physiotherapist, dietician and physical activity group. Manuals were developed for the implementers and included a detailed time table and step-by-step instructions on how to implement the maintenance programme. The Intervention Mapping protocol provided a useful framework to systematically plan a maintenance programme for the extensive SLIMMER intervention. The study showed that planning a maintenance programme can build on existing implementation structures of the extensive programme. Future research is needed to determine to what extent the maintenance programme contributes to sustained effects in participants of lifestyle interventions.

This paper describes development of Padres Trabajando por la Paz, a violence prevention intervention for Hispanic parents to increase parental monitoring. The intervention was developed using an innovative new program planning process: intervention mapping. Theory and empirical evidence broadly defined performance objectives and determinants of parental monitoring. These objectives were further refined through group and individual interviews with the target parent group. Learning objectives for the intervention guided the content of the intervention that used modeling as the primary method and role model stories as a strategy delivered through newsletters. Stage-matching members of the target population for their readiness to implement the parental monitoring behaviors further refined the social cognitive message design strategies. Intervention mapping provides an explicit theory- and data-driven guide for intervention development that maximizes intervention impact for a specific target population.

Full Text Available Abstract Background In order to increase the chances of success in new interventions in healthcare, it is generally recommended to tailor the intervention to the target setting and the target professionals. Nonetheless, pre-intervention studies are rarely conducted or are very limited in scope. Moreover, little is known about how to integrate the results of a pre-intervention study into an intervention. As part of a project to develop an intervention aimed at improving care for the elderly in France, a pre-intervention study was conducted to systematically gather data on the current practices, issues, and expectations of healthcare professionals and managers in order to determine the defining features of a successful intervention. Methods A qualitative study was carried out from 2004 to 2006 using a grounded theory approach and involving a purposeful sample of 56 healthcare professionals and managers in Paris, France. Four sources of evidence were used: interviews, focus groups, observation, and documentation. Results The stepwise approach comprised three phases, and each provided specific results. In the first step of the pre-intervention study, we gathered data on practices, perceived issues, and expectations of healthcare professionals and managers. The second step involved holding focus groups in order to define the characteristics of a tailor-made intervention. The third step allowed validation of the findings. Using this approach, we were able to design and develop an intervention in elderly care that met the professionals' and managers' expectations. Conclusion This article reports on an in-depth pre-intervention study that led to the design and development of an intervention in partnership with local healthcare professionals and managers. The stepwise approach represents an innovative strategy for developing tailored interventions, particularly in complex domains such as chronic care. It highlights the usefulness of seeking out the

Developing an intervention to overcome procrastination.

The main goal of this study was the development of a reliable intervention to overcome general procrastination orientated to college students, designed to be used in practical clinical work. The workshops involved six meetings based on behavioral and cognitive techniques, paradox intervention, and psychoeducation. 175 students participated voluntarily. Their procrastination levels were measured in a pretest, post-test, and a 3-month follow-up. After the first interview, the participants were randomly divided into three groups (Intervention A, Intervention B, and a control group with no intervention). There was a significant improvement after the intervention. After 3 months, the average score was still significantly lower than in the pretest, whereas the score of the control group remained unchanged. The participants in Workshop A scored significantly lower in the post-test than the ones in Workshop B. After 3 months, the participants in Workshop B scored significantly lower in the follow up. So both interventions resulted to be effective in reducing procrastination sustainably.

This paper describes the intervention planning process for the Home and Online Management and Evaluation of Blood Pressure (HOME BP), a digital intervention to promote hypertension self-management. It illustrates how a Person-Based Approach can be integrated with theory- and evidence-based approaches. The Person-Based Approach to intervention development emphasises the use of qualitative research to ensure that the intervention is acceptable, persuasive, engaging and easy to implement. Our intervention planning process comprised two parallel, integrated work streams, which combined theory-, evidence- and person-based elements. The first work stream involved collating evidence from a mixed methods feasibility study, a systematic review and a synthesis of qualitative research. This evidence was analysed to identify likely barriers and facilitators to uptake and implementation as well as design features that should be incorporated in the HOME BP intervention. The second work stream used three complementary approaches to theoretical modelling: developing brief guiding principles for intervention design, causal modelling to map behaviour change techniques in the intervention onto the Behaviour Change Wheel and Normalisation Process Theory frameworks, and developing a logic model. The different elements of our integrated approach to intervention planning yielded important, complementary insights into how to design the intervention to maximise acceptability and ease of implementation by both patients and health professionals. From the primary and secondary evidence, we identified key barriers to overcome (such as patient and health professional concerns about side effects of escalating medication) and effective intervention ingredients (such as providing in-person support for making healthy behaviour changes). Our guiding principles highlighted unique design features that could address these issues (such as online reassurance and procedures for managing concerns). Causal

Chronic pain is an important comorbidity among individuals with HIV. Behavioral interventions are widely regarded as evidence-based, efficacious non-pharmacologic interventions for chronic pain in the general population. An accepted principle in behavioral science is that theory-based, systematically-developed behavioral interventions tailored to the unique needs of a target population are most likely to be efficacious. Our aim was to use Intervention Mapping to systematically develop a Social Cognitive Theory (SCT)-based intervention for chronic pain tailored to individuals with HIV that will improve pain intensity and pain-related functional impairment. Our Intervention Mapping process was informed by qualitative inquiry of 24 patients and seven providers in an HIV primary care clinic. The resulting intervention includes group and one-on-one sessions and peer and staff interventionists. We also developed a conceptual framework that integrates our qualitative findings with SCT-based theoretical constructs. Using this conceptual framework as a guide, our future work will investigate the intervention's impact on chronic pain outcomes, as well as our hypothesized proximal mediators of the intervention's effect.

Paediatric interventional radiology

McLaren, Clare

2014-01-01

Paediatric interventional radiology (PIR) is a rapidly-growing subspecialty, which offers a wide range of procedures applicable to almost all areas of hospital paediatrics. There are many important differences between paediatric and adult practice in interventional radiology, including disease processes and treatment goals, anatomical considerations, periprocedural patient management, radiation exposure optimisation and legal aspects. The use of retrievable or absorbable interventional devices such as stents will probably become more widespread in PIR practice. Recent advances in the technology of imaging equipment have been accompanied by an increase in the complexity of the work done by the radiographer. These developments present challenges and opportunities related to training and maintenance of skills, staffing arrangements, and the potential for advanced practice. It is likely that specialisation in PIR will become a more common role for radiographers in the future

Latin American foreign exchange intervention - Updated

Da Silva, Sergio; Nunes, Mauricio

2007-01-01

We examine Latin American foreign exchange intervention in a framework where the exchange rate regime is endogenous and there exists an inefficient, equilibrium foreign exchange intervention bias. The model suggests that greater central bank independence is associated with lesser intervention in the foreign exchange market, and also with leaning-against-the-wind intervention. Both results are confirmed by data from 13 Latin American countries.

Study Design. Best evidence synthesis. Objective. To identify, critically appraise, and synthesize literature from 1980 through 2006 on noninvasive interventions for neck pain and its associated disorders. Summary of Background Data. No comprehensive systematic literature reviews have been published on interventions for neck pain and its associated disorders in the past decade. Methods. We systematically searched Medline and screened for relevance literature published from 1980 through 2006 on the use, effectiveness, and safety of noninvasive interventions for neck pain and associated disorders. Consensus decisions were made about the scientific merit of each article; those judged to have adequate internal validity were included in our best evidence synthesis. Results. Of the 359 invasive and noninvasive intervention articles deemed relevant, 170 (47%) were accepted as scientifically admissible, and 139 of these related to noninvasive interventions (including health care utilization, costs, and safety). For whiplash-associated disorders, there is evidence that educational videos, mobilization, and exercises appear more beneficial than usual care or physical modalities. For other neck pain, the evidence suggests that manual and supervised exercise interventions, low-level laser therapy, and perhaps acupuncture are more effective than no treatment, sham, or alternative interventions; however, none of the active treatments was clearly superior to any other in either the short-or long-term. For both whiplash-associated disorders and other neck pain without radicular symptoms, interventions that focused on regaining function as soon as possible are relatively more effective than interventions that do not have such a focus. Conclusion. Our best evidence synthesis suggests that therapies involving manual therapy and exercise are more effective than alternative strategies for patients with neck pain; this was also true of therapies which include educational interventions

Preventing Sexual Violence Through Bystander Intervention: Attitudes, Behaviors, Missed Opportunities, and Barriers to Intervention Among Australian University Students.

Science.gov (United States)

Kania, Rachel; Cale, Jesse

2018-03-01

The concept of bystander intervention is gaining popularity in universities as a mechanism to prevent sexual violence. Prior research has focused on correlates of bystanders' intentions to intervene and intervention behaviors in situations where there is a risk of sexual violence. The current study builds on this literature by exploring the nature of missed opportunities, including perceived barriers to intervention. In all, 380 Australian undergraduate university students completed an online survey. Measures included a rape myth acceptance scale, bystander intentions to intervene, actual intervention behaviors, missed opportunities for intervention, and perceived barriers for missed opportunities. Promisingly, students reported high levels of intentions to intervene in situations where there was a risk of sexual violence and reported relatively few missed opportunities to do so when these situations did occur. Intervention behaviors varied by important demographic characteristics such as gender, age, attitudes toward sexual violence, and the nature of the situation. Younger female students, with lower levels of rape myth acceptance, who had previously engaged in bystander intervention behaviors were more likely to report intentions to intervene in future risky situations, and female international students reported fewer missed opportunities for intervention. The most common barrier to intervention for identified missed opportunities was a failure to recognize situations as having a potential risk for sexual violence, and students were most likely to intervene in situations when the opportunity to help a friend in distress arose. This study provides some preliminary empirical evidence about bystander intervention against sexual violence among Australian university students, and identifies unique contexts for intervention and what current barriers to intervention may be.

The fundamental technique of performing percutaneous cardiovascular (CV) interventions has remained unchanged and requires operators to wear heavy lead aprons to minimize exposure to ionizing radiation. Robotic technology is now being utilized in interventional cardiology partially as a direct result of the increasing appreciation of the long-term occupational hazards of the field. This review was undertaken to report the clinical outcomes of percutaneous robotic coronary and peripheral vascular interventions. Areas covered: A systematic literature review of percutaneous robotic CV interventions was undertaken. The safety and feasibility of percutaneous robotically-assisted CV interventions has been validated in simple to complex coronary disease, and iliofemoral disease. Studies have shown that robotically-assisted PCI significantly reduces operator exposure to harmful ionizing radiation without compromising procedural success or clinical efficacy. In addition to the operator benefits, robotically-assisted intervention has the potential for patient advantages by allowing more accurate lesion length measurement, precise stent placement and lower patient radiation exposure. However, further investigation is required to fully elucidate these potential benefits. Expert commentary: Incremental improvement in robotic technology and telecommunications would enable treatment of an even broader patient population, and potentially provide remote robotic PCI.

Suicide intervention training evaluation: a preliminary report.

To date, very little work has been done on evaluating training in suicide intervention. This study developed and piloted a comprehensive method for evaluating suicide intervention training by applying three studies of immediate training effects on (a) suicide intervention abilities, (b) attitudes to suicide and suicide intervention, and (c) knowledge about suicide. The focus of the evaluation was a broadly used 2-day suicide intervention training program. Changes in suicide intervention abilities were measured by the Suicide Intervention Response Inventory (SIRI) and by performance in simulated suicide intervention situations, scored with the Suicide Intervention Protocol (SIP). Subjects consisted of 19 workshop participants in a pre-post condition and 17 participants in a post-test only condition. Results indicated significant increases in skills in suicide intervention situations. No significant effects were noted on the SIRI. Results from the attitudes and knowledge studies were very preliminary. They are reported here so that others may become aware of the methodology being used and the status of evaluation of the target program. Implications for further research are discussed.

The economics of interventional radiology

International Nuclear Information System (INIS)

Price, G.W.

1988-01-01

At a time when policy makers and regulators are scheming to reduce the costs and utilization of medical services, interventional radiology is poised for growth. Part of this potential for growth is based on wider acceptance of the procedures performed by interventional radiologists. A second factor in the growth potential is the relative value in cost of these procedures compared with alternative therapies. The author presents a discussion of the differences in the relative value of these procedures when performed by physicians of different specialties. This paper reviews the status of the economic climate in the health care delivery system and the role and potential growth of interventional radiology. This includes a review of current data on the utilization of interventional radiology procedures in the Medicare program. This overview includes a discussion of the initiatives of the federal government which directly impact interventional radiology

Tracing Early Interventions on Childhood Overweight

DEFF Research Database (Denmark)

Ditlevsen, Kia

This thesis presents results from a qualitative research project on early interventions to counter childhood obesity in Denmark. Overall, it was found that these interventions in families with preschool children were rarely performed. One barrier to the interventions is the structural setting...... in families with a non-western ethnic minority background and with low socioeconomic status. In families who participated in interventions, other social problems and a sense of insecurity caused by precarious living conditions of different kinds influenced the parents’ readiness to restrict children in order...... in the Danish health care system, which was found to be insufficient to initiate and facilitate early interventions. In addition, cultural stereotypes were found to affect the health care practitioners who are performing early interventions, and this can create reluctance to address overweight problems...

Streamlining interventional radiology admissions: The role of the interventional radiology clinic and physician's assistant

International Nuclear Information System (INIS)

White, R.I. Jr.; Rizer, D.M.; Shuman, K.; White, E.J.; Adams, P.; Doyle, K.; Kinnison, M.

1987-01-01

During a 5-year period (1982-1987), 376 patients were admitted to an interventional radiology service where they were managed by the senior physician and interventional radiology fellows. Sixty-eight percent of patients were admitted for angioplasty and 32% for elective embolotherapy/diagnostic angiography. A one-half-day, twice weekly interventional radiology clinic and employment of a physician's assistant who performed preadmission history and physicals and wrote orders accounted, in part, for a decrease in hospital stay length from 3.74 days (1982-1983) to 2.41 days (1986-1987). The authors conclude that use of the clinic and the physician's assistant streamlines patient flow and the admitting process and is partially responsible for a decreased length of stay for patients admitted to an interventional radiology service

Advances in psychological interventions for lifestyle disorders: overview of interventions in cardiovascular disorder and type 2 diabetes mellitus.

Sudhir, Paulomi M

2017-09-01

The present review examines the recent advances in psychological interventions for two major lifestyle disorders in adults namely, type 2 diabetes mellitus and cardiovascular disorders. The review summarizes findings from studies carried out between the years 2015 and 2017. The effectiveness of psychological interventions in the management of lifestyle disorders has been examined with respect to adaptation, self-care, adherence, negative emotions and improving quality of life. There is an increasing recognition that psychological interventions are important for prevention of lifestyle disorders and promotion of health. Key psychological interventions include self-management and educational interventions based on learning and motivational principles, patient empowerment, cognitive behaviour therapy, behavioural skills and coaching. Recent developments also include the use of information technology to deliver these interventions through internet, mobile applications and text messages. Another significant development is that of mindfulness-based interventions within the third-generation behaviour therapy approaches to reduce distress and increase acceptance. In addition, family and couples interventions have also been emphasised as necessary in maintenance of healthy behaviours. Studies examining psychological interventions in cardiovascular and type 2 diabetes mellitus support the efficacy of these interventions in bringing about changes in biochemical / physiological parameters and in psychological outcomes such as self-efficacy, knowledge, quality of life and a sense of empowerment.

The present study examined the effectiveness of a Growth Mindset intervention based on Dweck et al.'s (1995) theory in the Hungarian educational context. A cluster randomized controlled trial classroom experiment was carried out within the framework of a train-the-trainer intervention among 55 Hungarian 10th grade students with high Grade Point Average (GPA). The results suggest that students' IQ and personality mindset beliefs were more incremental in the intervention group than in the control group 3 weeks after the intervention. Furthermore, compared to both the baseline measure and the control group, students' amotivation decreased. However, no intrinsic and extrinsic motivation change was found. Students with low grit scores reported lower amotivation following the intervention. However, in the second follow-up measurement-the end of the semester-all positive changes disappeared; and students' GPA did not change compared to the previous semester. These results show that mindset beliefs are temporarily malleable and in given circumstances, they can change back to their pre-intervention state. The potential explanation is discussed in the light of previous mindset intervention studies and recent findings on wise social psychological interventions.

Especially for single older adults with chronic diseases, physical inactivity and a poor social network are regarded as serious threats to their health and independence. The Active Plus intervention is an automated computer-tailored eHealth intervention that has been proven effective to promote physical activity (PA) in the general population of adults older than 50 years. The aim of this study was to report on the methods and results of the systematic adaptation of Active Plus to the wishes and needs of the subgroup of single people older than 65 years who have one or more chronic diseases, as this specific target population may encounter specific challenges regarding PA and social network. The Intervention Mapping (IM) protocol was used to systematically adapt the existing intervention to optimally suit this specific target population. A literature study was performed, and quantitative as well as qualitative data were derived from health care professionals (by questionnaires, n=10) and the target population (by focus group interviews, n=14), which were then systematically integrated into the adapted intervention. As the health problems and the targeted behavior are largely the same in the original and adapted intervention, the outcome of the needs assessment was that the performance objectives remained the same. As found in the literature study and in data derived from health professionals and focus groups, the relative importance and operationalization of the relevant psychosocial determinants related to these objectives are different from the original intervention, resulting in a refinement of the change objectives to optimally fit the specific target population. This refinement also resulted in changes in the practical applications, program components, intervention materials, and the evaluation and implementation strategy for the subgroup of single, chronically impaired older adults. This study demonstrates that the adaptation of an existing intervention is an

Peer support is a promising strategy for the reduction of diabetes-related health disparities; however, few studies describe the development of such strategies in enough detail to allow for replication. The objective of this article is to describe the development of a 1-year peer support intervention to improve diabetes self-management among African American adults with diabetes in Alabama's Black Belt. We used principles of intervention mapping, including literature review, interviews with key informants, and a discussion group with community health workers, to guide intervention development. Qualitative data were combined with behavioral constructs and principles of diabetes self-management to create a peer support intervention to be delivered by trained peer advisors. Feedback from a 1-month pilot was used to modify the training and intervention. The resulting intervention includes a 2-day training for peer advisors, who were each paired with 3 to 6 clients. A one-on-one in-person needs assessment begins an intensive intervention phase conducted via telephone for 8 to 12 weeks, followed by a maintenance phase of at least once monthly contacts for the remainder of the intervention period. A peer support network and process measures collected monthly throughout the study supplement formal data collection points at baseline, 6 months, and 12 months. Intervention mapping provided a useful framework for the development of culturally relevant diabetes peer support intervention for African Americans living in Alabama's Black Belt. The process described could be implemented by others in public health to develop or adapt programs suitable for their particular community or context.

The Intervention Mapping (IM) protocol provides a structured framework to develop, implement, and evaluate complex interventions. The main objective of this review was to identify and describe the content of the interventions developed in the field of cancer with the IM protocol. Secondary objectives were to assess their fidelity to the IM protocol and to review their theoretical frameworks. Medline, Web of Science, PsycINFO, PASCAL, FRANCIS, and BDSP databases were searched. All titles and abstracts were reviewed. A standardized extraction form was developed. All included studies were reviewed by 2 reviewers blinded to each other. Sixteen studies were identified, and these reported 15 interventions. The objectives were to increase cancer screening participation (n = 7), early consultation (n = 1), and aftercare/quality of life among cancer survivors (n = 7). Six reported a complete participatory planning group, and 7 described a complete logic model of the problem. Ten studies described a complete logic model of change. The main theoretical frameworks used were the theory of planned behaviour (n = 8), the transtheoretical model (n = 6), the health belief model (n = 6), and the social cognitive theory (n = 6). The environment was rarely integrated in the interventions (n = 4). Five interventions were reported as effective. Culturally relevant interventions were developed with the IM protocol that were effective to increase cancer screening and reduce social disparities, particularly when they were developed through a participative approach and integrated the environment. Stakeholders' involvement and the role of the environment were heterogeneously integrated in the interventions. Copyright © 2017 John Wiley & Sons, Ltd.

Documenting pharmacist interventions on an intranet.

Simonian, Armen I

2003-01-15

The process of developing and implementing an intranet Web site for clinical intervention documentation is described. An inpatient pharmacy department initiated an organizationwide effort to improve documentation of interventions by pharmacists at its seven hospitals to achieve real-time capture of meaningful benchmarking data. Standardization of intervention types would allow the health system to contrast and compare medication use, process improvement, and patient care initiatives among its hospitals. After completing a needs assessment and reviewing current methodologies, a computerized tracking tool was developed in-house and integrated with the organization's intranet. Representatives from all hospitals agreed on content and functionality requirements for the Web site. The site was completed and activated in February 2002. Before this Web site was established, the most documented intervention types were Renal Adjustment and Clarify Dose, with a daily average of four and three, respectively. After site activation, daily averages for Renal Adjustment remained unchanged, but Clarify Dose is now documented nine times per day. Drug Information and i.v.-to-p.o. intervention types, which previously averaged less than one intervention per day, are now documented an average of four times daily. Approximately 91% of staff pharmacists are using this site. Future plans for this site include enhanced accessibility to the site with wireless personal digital assistants. The design and implementation of an intranet Web site to document pharmacists' interventions doubled the rate of intervention documentation and standardized the intervention types among hospitals in the health system.

Purpose: To investigate radiation exposure in computed tomography (CT)-guided interventions, to establish reference levels for exposure, and to discuss strategies for dose reduction. Materials and methods: We analyzed 1576 consecutive CT-guided procedures in 1284 patients performed over 4.5 years, including drainage placements; biopsies of different organs; radiofrequency and microwave ablations (RFA/MWA) of liver, bone, and lung tumors; pain blockages, and vertebroplasties. Data were analyzed with respect to scanner settings, overall radiation doses, and individual doses of planning CT series, CT intervention, and control CT series. Results: Eighy-five percent of the total radiation dose was applied during the pre- and post-interventional CT series, leaving only 15% applied by the CT-guided intervention itself. Single slice acquisition was associated with lower doses than continuous CT-fluoroscopy (37 mGy cm vs. 153 mGy cm, p < 0.001). The third quartile of radiation doses varied considerably for different interventions. The highest doses were observed in complex interventions like RFA/MWA of the liver, followed by vertebroplasty and RFA/MWA of the lung. Conclusions: This paper suggests preliminary reference levels for various intervention types and discusses strategies for dose reduction. A multicenter registry of radiation exposure including a broader spectrum of scanners and intervention types is needed to develop definitive reference levels.

Full Text Available Family interventions have produced benefits on clinical and family outcomes in long standing psychosis. However, little is known about the efficacy of such interventions in the early stages of psychosis. This article reviews published research over the last two decades on family intervention in first-episode psychosis. Electronic databases, such as PubMed, PsycINFO, and ScienceDirect, have been systematically searched. In addition, an exhaustive Internet search was also carried out using Google and Google Scholar to identify the potential studies that evaluated family interventions in first-episode psychosis. We have identified seven reports of five randomized controlled trials (RCTs and five non-randomized and uncontrolled studies of family intervention. Our review on 12 reports of family intervention studies has shown mixed effects on outcomes in first-episode psychosis. Most of the reports showed no added benefits or very short-term benefits on primary clinical or family outcome variables. There is a dearth of family intervention studies in first-episode psychosis. More RCTs are needed to reach reliable conclusions.

Full Text Available Positive interventions have been developed extensively in recent years and they have been tested and applied in very diverse settings. Despite the fact that most of the findings regarding their efficacy can be considered from positive to very positive, the possibility that, in some cases, positive interventions may have unexpected or even iatrogenic effects cannot be discarded. In this article, research from several sources is reviewed in order to inform decisions about what interventions might be inadequate for cases with specific characteristics or vulnerability traits. Finally, the importance of using positive interventions with caution and rigor even when working with individuals who do not have overt problems or psychological disorders is discussed.

Guidelines for radiological interventions

International Nuclear Information System (INIS)

Kauffmann, G.W.

1998-01-01

The German Radiological Society, in cooperation with other German professional bodies, set up draft Guidelines for Radiological Interventions and submitted them to the professional community for discussion. The Guidelines are meant to assess the potential of radiological interventions as treatment alternatives to surgery or aggressive therapy such as chemotherapy. In fact, technical practicability on its own is insufficient to warrant intervention. The Guidelines are systematically compiled notions and recommendations whose aim it is to provide support to physicians and patients in choosing suitable medical care provisions (prevention, diagnosis, therapy, aftertreatment) in specific circumstances. A complete Czech translation of the Guidelines is given. (P.A.)

Endovascular interventions for multiple trauma

2014-01-01

In recent years interventional radiology has significantly changed the management of injured patients with multiple trauma. Currently nearly all vessels can be reached within a reasonably short time with the help of specially preshaped catheters and guide wires to achieve bleeding control of arterial und venous bleeding. Whereas bleeding control formerly required extensive open surgery, current interventional methods allow temporary vessel occlusion (occlusion balloons), permanent embolization and stenting. In injured patients with multiple trauma preinterventional procedural planning is performed with the help of multidetector computed tomography whenever possible. Interventional radiology not only allows minimization of therapeutic trauma but also a considerably shorter treatment time. Interventional bleeding control has developed into a standard method in the management of vascular trauma of the chest and abdomen as well as in vascular injuries of the upper and lower extremities when open surgical access is associated with increased risk. Additionally, pelvic trauma, vascular trauma of the superior thoracic aperture and parenchymal arterial lacerations of organs that can be at least partially preserved are primarily managed by interventional methods. In an interdisciplinary setting interventional radiology provides a safe and efficient means of rapid bleeding control in nearly all vascular territories in addition to open surgical access. (orig.)

College students who violate alcohol policies are often mandated to participate in alcohol-related interventions. This study investigated (i) whether such interventions reduced drinking beyond the sanction alone, (ii) whether a brief motivational intervention (BMI) was more efficacious than two computer-delivered interventions (CDIs) and (iii) whether intervention response differed by gender. Randomized controlled trial with four conditions [brief motivation interventions (BMI), Alcohol 101 Plus™, Alcohol Edu for Sanctions(®), delayed control] and four assessments (baseline, 1, 6 and 12 months). Private residential university in the United States. Students (n = 677; 64% male) who had violated campus alcohol policies and were sanctioned to participate in a risk reduction program. Consumption (drinks per heaviest and typical week, heavy drinking frequency, peak and typical blood alcohol concentration), alcohol problems and recidivism. Piecewise latent growth models characterized short-term (1-month) and longer-term (1-12 months) change. Female but not male students reduced drinking and problems in the control condition. Males reduced drinking and problems after all interventions relative to control, but did not maintain these gains. Females reduced drinking to a greater extent after a BMI than after either CDI, and maintained reductions relative to baseline across the follow-up year. No differences in recidivism were found. Male and female students responded differently to sanctions for alcohol violations and to risk reduction interventions. BMIs optimized outcomes for both genders. Male students improved after all interventions, but female students improved less after CDIs than after BMI. Intervention effects decayed over time, especially for males. © 2010 The Authors, Addiction © 2010 Society for the Study of Addiction.

As survival estimates for cystic fibrosis (CF) steadily increase long-term management has become an important focus for intervention. Psychological interventions are largely concerned with emotional and social adjustments, adherence to treatment and quality of life, however no systematic review of such interventions has been undertaken for this disease. To describe the extent and quality of effectiveness studies utilising psychological interventions for CF and whether these interventions provide significant psychosocial and physical benefits in addition to standard care. Relevant trials were identified from searches of Ovid MEDLINE, the Cochrane trial registers for CF and Depression, Anxiety and Neurosis Groups and PsychINFO; unpublished trials were located through professional networks and Listserves. Most recent search: April 2003. This review included RCTs and quasi-randomised trials. Study participants were children and adults diagnosed with CF, and their immediate family members. Psychological interventions were from a broad range of modalities and outcomes were primarily psychosocial, although physical outcomes and cost effectiveness were also considered. Two reviewers independently selected relevant trials and assessed their methodological quality. For binary and continuous outcomes a pooled estimate of treatment effect was calculated for each outcome. This review is based on the findings of eight studies, representing data from a total of 358 participants. Studies fell into four conceptually similar groups: (1) gene pre-test education counselling for relatives of those with CF (one study); (2) biofeedback, massage and music therapy to assist physiotherapy (three studies); (3) behavioural intervention to improve dietary intake in children up to 12 years (three studies); and (4) self-administration of treatments to improve quality of life in adults (one study). Interventions were largely educational or behavioural, targeted at specific treatment concerns

Proposals for regulating future humanitarian interventions

Raičević Nebojša

2014-01-01

Full Text Available Although the legality of approved humanitarian intervention is undisputable in the positive international law, this legal institute should be further regulated in order to remove certain legal ambiguity and difficulties in its application. The future regulation of humanitarian intervention may be carried out in one of the three ways: by adopting a special international treaty, by entering amendments in the UN Charter, or by embarking on the factual revision of the UN Charter. Due to the limiting effects of Article 103 of the UN Charter as well as the problematic status of UN member states which would not ratify the international agreements on humanitarian intervention, the regulation of future humanitarian intervention seems to be the least likely option. Formal revision of the UN Charter is not a viable option either because, thus far, the major world powers have been against introducing any substantial changes to this treaty. For this reason, the factual revision of the UN Charter is currently the most appropriate way of regulating future humanitarian interventions. When it comes to substantive rules governing humanitarian intervention, it is necessary to focus on the problem of humanitarian intervention decision-making as well as on the conditions and criteria for the approval and carrying out a humanitarian intervention. The UN Security Council must retain the right to decide on approving such an intervention but it is also necessary to establish an independent expert body whose task would be to determine the presence of serious and mass violations of human rights in a specific country and notify the Security Council about such occurrences. The specification of conditions and criteria for undertaking a humanitarian intervention should strengthen its legitimacy and prevent unreasonable disruption of states' territorial integrity and political independence.

Background: While the incidence rate of the colorectal cancer (CRC) has been increasing over the last three decades in Iran, very limited interventions to increase CRC screening have been developed for Iranian population. The purpose of this study was to describe the use of Intervention Mapping (IM) for applying theory and evidence and considering local contexts to develop a CRC screening program among adults in Iran. Materials and Methods: From April 2014 to July 2016 following the IM process, six steps were formulated and implemented. First a need assessment was conducted involving relevant stakeholders and using focus groups discussions (n=10), individual interviews (n=20), and a household survey (n= 480). Then a matrix of change objectives was developed for each behavioral outcome and theoretical methods and their practical applications were identified to guide intervention development and implementation. A multi-component intervention was developed and piloted. Decision on suitable parts of intervention was made based on feedback of pilot study. Finally, evaluation plan including process and outcome evaluation was generated and conducted to inform future scale up. Results: The needs assessment highlighted factors affecting CRC screening including knowledge, self efficacy, social support and perceived benefit and barriers (financial problems, fear of detection of cancer and etc). Results of needs assessment were used to develop next steps IM. The program utilized methods like information delivery, modeling, and persuasion. Practical applications included video presentation, group discussion, role playing and postcards.This program was assessed through a cluster-randomized controlled trial. Results showed that there were significant differences in CRC screening uptake between intervention groups and control (Pintervention addressing CRC screening among Iranian population.

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental trouble which prevents the child from socio-communicative interaction, and learning from his environment. Non-medical early intervention attempts to improve prognosis. We will review the main current hypothesis, intervention models and scientific supports about early intervention. We conducted a search of the literature published on Medline between 2010 and 2015 related to intervention models provided to children with ASD aged less than 3 years. Data were extracted from systematic reviews and recent randomized controlled trials with moderate to high GRADE quality of evidence. Early intervention refers to brain plasticity theory. With the epidemiological studies of infant "at risk" there is an attempt to intervene earlier before full syndrome is present. Interventions tend to follow more on a developmental hierarchy of socio-communicative skills and to focus on the dyadic relation between the child and the caregivers to improve the core autistic symptoms. Over the last 6 years, there's been news and fine-tuned ways about early intervention, and more and more systematic evaluation. However, there are only few interventions which were evaluated in trial with a strong GRADE recommendation and all of them have methodological concerns. It is important to be cautious in recommendations for mental health politic, even if it is important to improve access to services for all children and their families, hence finance and design rigorous project in research.

The term adaptive intervention has been used in behavioral medicine to describe operationalized and individually tailored strategies for prevention and treatment of chronic, relapsing disorders. Control systems engineering offers an attractive means for designing and implementing adaptive behavioral interventions that feature intensive measurement and frequent decision-making over time. This is illustrated in this paper for the case of a low-dose naltrexone treatment intervention for fibromyalgia. System identification methods from engineering are used to estimate dynamical models from daily diary reports completed by participants. These dynamical models then form part of a model predictive control algorithm which systematically decides on treatment dosages based on measurements obtained under real-life conditions involving noise, disturbances, and uncertainty. The effectiveness and implications of this approach for behavioral interventions (in general) and pain treatment (in particular) are demonstrated using informative simulations.

The main goals of the OG21 initiative are to (1) develop new technology and knowledge to increase the value creation of Norwegian oil and gas resources and (2) enhance the export of Norwegian oil and gas technology. The OG21 Cost-effective Drilling and Intervention (CEDI) Technology Target Area (TTA) has identified some key strategic drilling and well intervention needs to help meet the goals of OG21. These key strategic drilling and well intervention needs are based on a review of present and anticipated future offshore-Norway drilling and well intervention conditions and the Norwegian drilling and well intervention industry. A gap analysis has been performed to assess the extent to which current drilling and well intervention research and development and other activities will meet the key strategic needs. Based on the identified strategic drilling and well intervention needs and the current industry res each and development and other activities, the most important technology areas for meeting the OG21 goals are: environment-friendly and low-cost exploration wells; low-cost methods for well intervention/sidetracks; faster and extended-reach drilling; deep water drilling, completion and intervention; offshore automated drilling; subsea and sub-ice drilling; drilling through basalt and tight carbonates; drilling and completion in salt formation. More specific goals for each area: reduce cost of exploration wells by 50%; reduce cost for well intervention/sidetracks by 50%; increase drilling efficiency by 40%; reduce drilling cost in deep water by 40 %; enable offshore automated drilling before 2012; enable automated drilling from seabed in 2020. Particular focus should be placed on developing new technology for low-cost exploration wells to stem the downward trends in the number of exploration wells drilled and the volume of discovered resources. The CEDI TTA has the following additional recommendations: The perceived gaps in addressing the key strategic drilling and

Theory, evidence and Intervention Mapping to improve behavior nutrition and physical activity interventions

Directory of Open Access Journals (Sweden)

Ferreira Isabel

2005-04-01

Full Text Available Abstract Background The present paper intends to contribute to the debate on the usefulness and barriers in applying theories in diet and physical activity behavior-change interventions. Discussion Since behavior theory is a reflection of the compiled evidence of behavior research, theory is the only foothold we have for the development of behavioral nutrition and physical activity interventions. Application of theory should improve the effectiveness of interventions. However, some of the theories we use lack a strong empirical foundation, and the available theories are not always used in the most effective way. Furthermore, many of the commonly-used theories provide at best information on what needs to be changed to promote healthy behavior, but not on how changes can be induced. Finally, many theories explain behavioral intentions or motivation rather well, but are less well-suited to explaining or predicting actual behavior or behavior change. For more effective interventions, behavior change theory needs to be further developed in stronger research designs and such change-theory should especially focus on how to promote action rather than mere motivation. Since voluntary behavior change requires motivation, ability as well as the opportunity to change, further development of behavior change theory should incorporate environmental change strategies. Conclusion Intervention Mapping may help to further improve the application of theories in nutrition and physical activity behavior change.

Pediatric obesity has become increasingly prevalent over recent decades. In view of the psychosocial and physical health risks, and the high likelihood that children with obesity will grow to become adults with obesity, there is a clear need to develop evidence-based interventions that can be delivered in the health care system to optimize the health and well-being of children with obesity and their families. The aim of this paper is to describe the development, implementation, and planned evaluation of a parent-based weight management intervention designed for parents of 8-12 year olds with obesity. The principles of Intervention Mapping (IM) were used to develop an intervention called Parents as Agents of Change (PAC © ). From 2006 to 2009, an environmental scan plus qualitative (individual interviews with parents and children), quantitative (medical record reviews), and literature review data were collected to gain broad insight into family factors related to pediatric obesity and its management. Theoretical frameworks and empirical evidence guided curriculum development, which was founded primarily on the tenets of family systems theory and cognitive behavioral theory. PAC was developed as a manualized, 16-session, group-based, health care professional-led intervention for parents to address individual, family, and environmental factors related to the management of pediatric obesity. The intervention was refined based on feedback from local and international experts, and has been implemented successfully in a multi-disciplinary weight management centre in a children's hospital. IM provided a practical framework to guide the systematic development of a pediatric weight management intervention for parents of children with obesity. This logical, step-by-step process blends theory and practice and is broadly applicable in the context of obesity management intervention development and evaluation. Following intervention development, the PAC intervention was

School-based interventions to address bullying

Peter K. Smith

2016-10-01

Full Text Available Following some background studies on the nature of school bullying, its prevalence, and the negative consequences it can have, this article reviews the history of anti-bullying interventions over the last 30 years. It considers several major programmes in detail, such as the Olweus Bullying Prevention Program, KiVa, Steps to Respect, and Friendly Schools. The nature and evaluation of the interventions is discussed, followed by a review of meta-analyses of the programmes effectiveness. Issues considered are the effect at different ages; components of interventions; work with peers; disciplinary methods, non-punitive and restorative approaches; challenges regarding cyberbullying; the role of parents; the role of teachers and teacher training; set menu versus à la carte approaches; sustainability of interventions and societal context. Conclusions show that interventions have had some success, with traditional bullying. However, further progress is needed in strengthening theoretical underpinnings to interventions, and in tackling cyberbullying.

Positive psychological interventions (PPI) are increasingly employed as a coping strategy with physical and mental conditions, including neurological diseases. Its effectiveness on improving wellbeing in people with epilepsy (PWE) has been shown in a few studies. This study aimed to explore factors related to participants' willingness to engage in psychological interventions from the perspective of patients with epilepsy. Participants answered a needs assessment questionnaire eliciting information about their illness perception (Brief Illness Perception Questionnaire (Brief-IPQ)), emotions (Hospital Anxiety and Depression Scale (HADS)), willingness to participate in psychological interventions, preferences in types of PPI and intervention designs, as well as barriers in seeking mental health services. A total of 154 patients with epilepsy participated, with a mean age of 37.3years (range 16-86years). Most patients had focal epilepsy (68.2%), and drug-resistant (59.1%). Majority (71.4%) of them indicated a strong willingness to participate in PPI. Out of nine types of PPI, character strengths, mindfulness-based and expressive-based interventions were highly preferred. Those with negative illness perception (p=0.001), anxiety (p=0.004), and being unemployed (p=0.048) were more willing to participate in PPI. Most participants preferred group rather than individual session, and a shorter duration (30min) was favored by most. This study captured the self-report willingness to participate in psychological interventions. Findings suggested that psychological interventions delivered in short-group session were highly preferred. Future study is required to determine the feasibility of such design for patients with epilepsy. Copyright © 2017 Elsevier Inc. All rights reserved.

Endovascular interventional magnetic resonance imaging

2003-01-01

Minimally invasive interventional radiological procedures, such as balloon angioplasty, stent placement or coiling of aneurysms, play an increasingly important role in the treatment of patients suffering from vascular disease. The non-destructive nature of magnetic resonance imaging (MRI), its ability to combine the acquisition of high quality anatomical images and functional information, such as blood flow velocities, perfusion and diffusion, together with its inherent three dimensionality and tomographic imaging capacities, have been advocated as advantages of using the MRI technique for guidance of endovascular radiological interventions. Within this light, endovascular interventional MRI has emerged as an interesting and promising new branch of interventional radiology. In this review article, the authors will give an overview of the most important issues related to this field. In this context, we will focus on the prerequisites for endovascular interventional MRI to come to maturity. In particular, the various approaches for device tracking that were proposed will be discussed and categorized. Furthermore, dedicated MRI systems, safety and compatibility issues and promising applications that could become clinical practice in the future will be discussed. (topical review)

Reasons for Testing Mediation in the Absence of an Intervention Effect: A Research Imperative in Prevention and Intervention Research.

Science.gov (United States)

O'Rourke, Holly P; MacKinnon, David P

2018-03-01

Mediation models are used in prevention and intervention research to assess the mechanisms by which interventions influence outcomes. However, researchers may not investigate mediators in the absence of intervention effects on the primary outcome variable. There is emerging evidence that in some situations, tests of mediated effects can be statistically significant when the total intervention effect is not statistically significant. In addition, there are important conceptual and practical reasons for investigating mediation when the intervention effect is nonsignificant. This article discusses the conditions under which mediation may be present when an intervention effect does not have a statistically significant effect and why mediation should always be considered important. Mediation may be present in the following conditions: when the total and mediated effects are equal in value, when the mediated and direct effects have opposing signs, when mediated effects are equal across single and multiple-mediator models, and when specific mediated effects have opposing signs. Mediation should be conducted in every study because it provides the opportunity to test known and replicable mediators, to use mediators as an intervention manipulation check, and to address action and conceptual theory in intervention models. Mediators are central to intervention programs, and mediators should be investigated for the valuable information they provide about the success or failure of interventions.

We describe our experience of using the Medical Research Council framework on complex interventions to guide the development and evaluation of an intervention to prevent obesity by modifying infant feeding behaviours. We reviewed the epidemiological evidence on early life risk factors for obesity and interventions to prevent obesity in this age group. The review suggested prevention of excess weight gain in bottle-fed babies and appropriate weaning as intervention targets; hence we undertook systematic reviews to further our understanding of these behaviours. We chose theory and behaviour change techniques that demonstrated evidence of effectiveness in altering dietary behaviours. We subsequently developed intervention materials and evaluation tools and conducted qualitative studies with mothers (intervention recipients) and healthcare professionals (intervention deliverers) to refine them. We developed a questionnaire to assess maternal attitudes and feeding practices to understand the mechanism of any intervention effects.

Full Text Available Introduction. We describe our experience of using the Medical Research Council framework on complex interventions to guide the development and evaluation of an intervention to prevent obesity by modifying infant feeding behaviours. Methods. We reviewed the epidemiological evidence on early life risk factors for obesity and interventions to prevent obesity in this age group. The review suggested prevention of excess weight gain in bottle-fed babies and appropriate weaning as intervention targets; hence we undertook systematic reviews to further our understanding of these behaviours. We chose theory and behaviour change techniques that demonstrated evidence of effectiveness in altering dietary behaviours. We subsequently developed intervention materials and evaluation tools and conducted qualitative studies with mothers (intervention recipients and healthcare professionals (intervention deliverers to refine them. We developed a questionnaire to assess maternal attitudes and feeding practices to understand the mechanism of any intervention effects. Conclusions. In addition to informing development of our specific intervention and evaluation materials, use of the Medical Research Council framework has helped to build a generalisable evidence base for early life nutritional interventions. However, the process is resource intensive and prolonged, and this should be taken into account by public health research funders. This trial is registered with ISRTCN: 20814693 Baby Milk Trial.

The Internet is now an indispensable part of daily life for the majority of people in many parts of the world. It offers an additional means of effecting changes to behaviour such as smoking. To determine the effectiveness of Internet-based interventions for smoking cessation. We searched the Cochrane Tobacco Addiction Group Specialized Register. There were no restrictions placed on language of publication or publication date. The most recent search was conducted in April 2013. We included randomized and quasi-randomized trials. Participants were people who smoked, with no exclusions based on age, gender, ethnicity, language or health status. Any type of Internet intervention was eligible. The comparison condition could be a no-intervention control, a different Internet intervention, or a non-Internet intervention. Two authors independently assessed and extracted data. Methodological and study quality details were extracted using a standardized form. We extracted smoking cessation outcomes of six months follow-up or more, reporting short-term outcomes where longer-term outcomes were not available. We reported study effects as a risk ratio (RR) with a 95% confidence interval (CI). Clinical and statistical heterogeneity limited our ability to pool studies. This updated review includes a total of 28 studies with over 45,000 participants. Some Internet programmes were intensive and included multiple outreach contacts with participants, whilst others relied on participants to initiate and maintain use.Fifteen trials compared an Internet intervention to a non-Internet-based smoking cessation intervention or to a no-intervention control. Ten of these recruited adults, one recruited young adult university students and two recruited adolescents. Seven of the trials in adults had follow-up at six months or longer and compared an Internet intervention to usual care or printed self help. In a post hoc subgroup analysis, pooled results from three trials that compared

Full Text Available Despite disparities in the conceptualization of work–life balance (WLB and work–life harmony (WLH in the literature, there remains no evidence till date to validate these differences. Furthermore, there are currently no insights that shed light on the relationship between work–life initiatives and key business strategies of contemporary organizations. Hence, the current study investigated the differences between the constructs of WLB and WLH using a cognitive dissonance approach and assessed the impact of work–life interventions, based on these approaches, on individual creativity at work. Hundred participants, age ranging from 18 to 32 years (M = 23.94, SD = 3.87, with at least 6 months of working experience were recruited. Using an online questionnaire, participants were randomly assigned into WLB (n = 55 or WLH (n = 45 conditions. Participants were tasked to complete pre- and post-intervention measures of individual creativity, as well as a manipulation check using a cognitive dissonance scale. Results showed that participants in the WLB condition elicit higher levels of cognitive dissonance compared with participants in the WLH condition. This indicates an implicit difference in the constructs of WLB and harmony. Second, findings also suggest that work–life interventions adopting a WLH approach will have a more positive impact on individuals’ creativity at work compared with interventions targeted at achieving balance. Research, practical, and cultural implications of the findings are discussed in the article.

Vietnam is experiencing an epidemiologic transition with an increased prevalence of non-communicable diseases. Novel, large-scale, effective, and sustainable interventions to control hypertension in Vietnam are needed. We report the results of a cluster-randomized feasibility trial at 3 months follow-up conducted in Hung Yen province, Vietnam, designed to evaluate the feasibility and acceptability of two community-based interventions to improve hypertension control: a "storytelling" intervention, "We Talk about Our Hypertension," and a didactic intervention. The storytelling intervention included stories about strategies for coping with hypertension, with patients speaking in their own words, and didactic content about the importance of healthy lifestyle behaviors including salt reduction and exercise. The didactic intervention included only didactic content. The storytelling intervention was delivered by two DVDs at 3-month intervals; the didactic intervention included only one installment. The trial was conducted in four communes, equally randomized to the two interventions. The mean age of the 160 study patients was 66 years, and 54% were men. Most participants described both interventions as understandable, informative, and motivational. Between baseline and 3 months, mean systolic blood pressure declined by 8.2 mmHg (95% CI 4.1-12.2) in the storytelling group and by 5.5 mmHg (95% CI 1.4-9.5) in the didactic group. The storytelling group also reported a significant increase in hypertension medication adherence. Both interventions were well accepted in several rural communities and were shown to be potentially effective in lowering blood pressure. A large-scale randomized trial is needed to compare the effectiveness of the two interventions in controlling hypertension. ClinicalTrials.gov, NCT02483780.

To determine what interventions are effective in promoting cycling, the size of the effects of interventions, and evidence of any associated benefits on overall physical activity or anthropometric measures. Systematic review. Published and unpublished reports in any language identified by searching 13 electronic databases, websites, reference lists, and existing systematic reviews, and papers identified by experts in the field. Review methods Controlled "before and after" experimental or observational studies of the effect of any type of intervention on cycling behaviour measured at either individual or population level. Twenty five studies (of which two were randomised controlled trials) from seven countries were included. Six studies examined interventions aimed specifically at promoting cycling, of which four (an intensive individual intervention in obese women, high quality improvements to a cycle route network, and two multifaceted cycle promotion initiatives at town or city level) were found to be associated with increases in cycling. Those studies that evaluated interventions at population level reported net increases of up to 3.4 percentage points in the population prevalence of cycling or the proportion of trips made by bicycle. Sixteen studies assessing individualised marketing of "environmentally friendly" modes of transport to interested households reported modest but consistent net effects equating to an average of eight additional cycling trips per person per year in the local population. Other interventions that targeted travel behaviour in general were not associated with a clear increase in cycling. Only two studies assessed effects of interventions on physical activity; one reported a positive shift in the population distribution of overall physical activity during the intervention. Community-wide promotional activities and improving infrastructure for cycling have the potential to increase cycling by modest amounts, but further controlled

Therapeutic interventions in cerebral palsy.

Various therapeutic interventions have been used in the management of children with cerebral palsy. Traditional physiotherapy and occupational therapy are widely used interventions and have been shown to be of benefit in the treatment of cerebral palsy. Evidence in support of the effectiveness of the neurodevelopmental treatment is equivocal at best. There is evidence to support the use and effectiveness of neuromuscular electrical stimulation in children with cerebral palsy. The effectiveness of many other interventions used in the treatment of cerebral palsy has not been clearly established based on well-controlled trials. These include: sensory integration, body-weight support treadmill training, conductive education, constraint-induced therapy, hyperbaric oxygen therapy, and the Vojta method. This article provides an overview of salient aspects of popular interventions used in the management of children with cerebral palsy.

E-health interventions for suicide prevention.

Christensen, Helen; Batterham, Philip J; O'Dea, Bridianne

2014-08-12

Many people at risk of suicide do not seek help before an attempt, and do not remain connected to health services following an attempt. E-health interventions are now being considered as a means to identify at-risk individuals, offer self-help through web interventions or to deliver proactive interventions in response to individuals' posts on social media. In this article, we examine research studies which focus on these three aspects of suicide and the internet: the use of online screening for suicide, the effectiveness of e-health interventions aimed to manage suicidal thoughts, and newer studies which aim to proactively intervene when individuals at risk of suicide are identified by their social media postings. We conclude that online screening may have a role, although there is a need for additional robust controlled research to establish whether suicide screening can effectively reduce suicide-related outcomes, and in what settings online screening might be most effective. The effectiveness of Internet interventions may be increased if these interventions are designed to specifically target suicidal thoughts, rather than associated conditions such as depression. The evidence for the use of intervention practices using social media is possible, although validity, feasibility and implementation remains highly uncertain.

Providing a detailed description of two participants who failed to acquire functional communication skills following a verbal modelling intervention and Picture Exchange Communication System (PECS) training. Single-case research; Independent verbal requests, imitated verbal requests, word approximations and independent picture requests were assessed in a toddler and a pre-schooler with autism before and during two interventions. Although both participants used some vocalizations over the course of the study, experimental control was not demonstrated and the participants did not acquire a functional communication system prior to the cessation of intervention. Future research should include additional, detailed reports that provide insight to why some children with autism do not respond to particular communication interventions and should investigate the pairing of particular child characteristics with targeted interventions.

Community interventions are complex social processes that need to move beyond single interventions and outcomes at individual levels of short-term change. A scientific paradigm is emerging that supports collaborative, multilevel, culturally situated community interventions aimed at creating sustainable community-level impact. This paradigm is rooted in a deep history of ecological and collaborative thinking across public health, psychology, anthropology, and other fields of social science. The new paradigm makes a number of primary assertions that affect conceptualization of health issues, intervention design, and intervention evaluation. To elaborate the paradigm and advance the science of community intervention, we offer suggestions for promoting a scientific agenda, developing collaborations among professionals and communities, and examining the culture of science.

Ramsey, Alex T; Montgomery, Katherine

2014-10-01

Despite concerns around the use of technology-based interventions, they are increasingly being employed by social workers as a direct practice methodology to address the mental health needs of vulnerable clients. Researchers have highlighted the importance of using innovative technologies within social work practice, yet little has been done to summarize the evidence and collectively assess findings. In this systematic review, we describe accounts of technology-based mental health interventions delivered by social workers over the past 10 years. Results highlight the impacts of these tools and summarize advantages and disadvantages to utilizing technologies as a method for delivering or facilitating interventions.

Operational intervention levels (OILs): a tool to overcome differences in intervention levels?

International Nuclear Information System (INIS)

Kirchner, Gerald; Wirth, Erich

2008-01-01

The intervention levels for evacuation, sheltering and iodine blockade still differ in many countries, although international organisation like IAEA, NEA or ICRP aspire to harmonise them on an international level. Even if the dose values of the limits are in agreement, they are not necessarily comparable because the type of dose (projected dose, averted dose), the respected exposure pathways (external dose, inhalation, ingestion) or the integration time might differ significantly. The question is raised, how can harmonisation being achieved? International organisations recommend 'operational intervention levels' (OILs) for promptly assessing the results of environmental monitoring and to decide on protective actions. OILs are measurable values derived from dose limits. Best examples are the derived intervention levels for food and feed in the codex alimentarius or by the EC, which limit the ingestion dose to about 5 mSv/a. This paper discusses the properties and potential use of OILs, identifies and derives useful OILs and addresses their benefit in practise both for early and later countermeasures. Furthermore it is discussed whether OILs might be a useful tool to overcome national differences in intervention levels because an OIL value covers a relative wide range of the projected dose due to the uncertainty of the parameters needed for derivation.

Vaginismus is an involuntary contraction of the vaginal muscles which makes sexual intercourse difficult or impossible. It is one of the more common female psychosexual problems. Various therapeutic strategies for vaginismus, such as sex therapy and desensitisation, have been proposed, and uncontrolled case series appear promising. To assess the effects of different interventions for vaginismus. We searched the Cochrane Depression, Anxiety and Neurosis Group's Specialised Register (CCDANCTR-Studies and CCDANCTR-References) to August 2012. This register contains relevant randomised controlled trials from: The Cochrane Library (all years), EMBASE (1974 to date), MEDLINE (1950 to date) and PsycINFO (1967 to date). We searched reference lists and conference abstracts. We contacted experts in the field regarding unpublished material. Controlled trials comparing treatments for vaginismus with another treatment, a placebo treatment, treatment as usual or waiting list control. The review authors extracted data which we verified with the trial investigator where possible. Five studies were included, of which four with a total of 282 participants provided data. No meta-analysis was possible due to heterogeneity of comparisons within included studies as well as inadequate reporting of data. All studies were considered to be at either moderate or high risk of bias. The results of this systematic review indicate that there is no clinical or statistical difference between systematic desensitisation and any of the control interventions (either waiting list control, systematic desensitisation combined with group therapy or in vitro (with women under instruction by the therapist) desensitisation) for the treatment of vaginismus. The drop-out rates were higher in the waiting list groups. A clinically relevant effect of systematic desensitisation when compared with any of the control interventions cannot be ruled out. None of the included trials compared other behaviour therapies (e

Exploring the discrepancy in sex-ratio among interventional cardiologists by analysing the population of the female interventionalist. Despite an increase number of women who graduate from medical school in France during the last generation today, women represent only 24% of all cardiologists and 3% are interventional cardiologists. To face this international gender-based issue of interventional cardiology, committees were established in US (WIN) and recently within the EAPCI: the Women EAPCI chaired by Drs Mehilli and Mauri. In France, the Intervention'Elles committee emerged in order to participate in this concern. As a first initiative, the Intervention'Elles group launched an e-survey to obtain information on the population of French female interventional cardiologists, focused on demography, work patterns, maternity and radiation exposure. Mean age is 40 years old (±7,4), 68% are working in large volume center, 28% have also structural interventional activity. Only 40% have left arm coverage. Despite 80% of French female interventional cardiologists wear personal dosimeters only 45% of them have a dosimetry feedback. Interestingly, even if 54% of women have children (mean: 1.9±1) 28% of them report that childbearing had interfered with their career plan. This questionnaire identifies for the first time the women population in interventional cardiology in France and highlights some of the issues encountered in more detail. This first descriptive step would help to develop strategies for attaining gender equality in interventional cardiology. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

This study was conducted to survey of radiation safety control and to measure occupational radiation exposure dose of staff in interventional radiology in Korea. Interventioanl radiology requires the operator and assisting personnel to remain close to the patient, and thus close to primary beams of radiation. Therefore exposure doses of these personnel are significant from a radiological protection point of view. We surveyed the status of radiation safety on interventional radiology of 72 hospitals. The result were that 119 radiation equipments are using in interventional radiology and 744 staffs are composed of 307 radiologists, 116 residents of radiology, 5 general physicians, 171 radiologic technologists and 145 nurses. 81.4% and 20.2 % of operating physicians are using neck collar protector and goggle respectively. The average radiation dose was measured 0.46±0.15 mSv/10 hours fluoroscopy inside examination room in radiation protection facilities. Occupational radiation exposure data on the staff were assessed in interventional radiology procedures from 8 interventional radiology equipments of 6 university hospitals. The dose measurements were made by placing a thermoluminesent dosimeter(TLD) on various body surface of operation and assistant staff during actual interventional radiology. The measured points were the corner of the eyes, neck(on the thyroid) , wrists, chest(outside and inside of the protector), and back. Average radiation equivalent dose of the corner of left eye and left wrist of operating physicians were 1.19 mSv(0.11∼4.13 mSv)/100 minutes fluoroscopy and 4.32 mSv(0.16∼11.0 mSv)/100 minutes fluoroscopy respectively. Average exposure dose may vary depending on the type of procedure, personal skills and the quality of equipment. These results will be contributed to prepare the guide line in interventional radiology in Korea

Full Text Available Abstract Background To develop more efficient programmes for promoting dietary and/or physical activity change (in order to prevent type 2 diabetes it is critical to ensure that the intervention components and characteristics most strongly associated with effectiveness are included. The aim of this systematic review of reviews was to identify intervention components that are associated with increased change in diet and/or physical activity in individuals at risk of type 2 diabetes. Methods MEDLINE, EMBASE, CINAHL, PsycInfo, and the Cochrane Library were searched for systematic reviews of interventions targeting diet and/or physical activity in adults at risk of developing type 2 diabetes from 1998 to 2008. Two reviewers independently selected reviews and rated methodological quality. Individual analyses from reviews relating effectiveness to intervention components were extracted, graded for evidence quality and summarised. Results Of 3856 identified articles, 30 met the inclusion criteria and 129 analyses related intervention components to effectiveness. These included causal analyses (based on randomisation of participants to different intervention conditions and associative analyses (e.g. meta-regression. Overall, interventions produced clinically meaningful weight loss (3-5 kg at 12 months; 2-3 kg at 36 months and increased physical activity (30-60 mins/week of moderate activity at 12-18 months. Based on causal analyses, intervention effectiveness was increased by engaging social support, targeting both diet and physical activity, and using well-defined/established behaviour change techniques. Increased effectiveness was also associated with increased contact frequency and using a specific cluster of "self-regulatory" behaviour change techniques (e.g. goal-setting, self-monitoring. No clear relationships were found between effectiveness and intervention setting, delivery mode, study population or delivery provider. Evidence on long

To examine published evidence on the effectiveness of mind-body interventions during pregnancy on perceived stress, mood, and perinatal outcomes. Computerized searches of PubMed, Cinahl, PsycINFO, and the Cochrane Library. Twelve out of 64 published intervention studies between 1980 and February 2007 of healthy, adult pregnant women met criteria for review. Studies were categorized by type of mind-body modality used. Progressive muscle relaxation was the most common intervention. Other studies used a multimodal psychoeducation approach or a yoga and meditation intervention. The research contained methodological problems, primarily absence of a randomized control group or failure to adequately control confounding variables. Nonetheless, there was modest evidence for the efficacy of mind-body modalities during pregnancy. Treatment group outcomes included higher birthweight, shorter length of labor, fewer instrument-assisted births, and reduced perceived stress and anxiety. There is evidence that pregnant women have health benefits from mind-body therapies used in conjunction with conventional prenatal care. Further research is necessary to build on these studies in order to predict characteristics of subgroups that might benefit from mind-body practices and examine cost effectiveness of these interventions on perinatal outcomes.

Cardiovascular and interventional radiology

White, R.I. Jr.

1985-01-01

A symposium of eight short but complete papers giving an overview of interventional radiology is presented. Organized by Dr. William Casarella, this symposium is certainly the most current review of the subject available. This year's cardiovascular section is again heavily weighted toward interventional radiology. Abrams and Doubilet's article on the underutilization of angioplasty is important because it describes the cost effectiveness of this method. Most health planners, right or wrong, have complained about overutilization of diagnostic radiology procedures. In general, the opposite is true for interventional procedures - they are underutilized. If the authors draw the attention of their hospital administrators to these approaches and also produce the data on long-term follow-up for our medical colleagues, interventional radiology may realize its full potential. Articles on cardiac magnetic resonance imaging are beginning to appear and this technique seems to have great potential. An important article, which is the first prospective study comparing lung scintigraphy and pulmonary angiography in the diagnosis of pulmonary embolism, supports the increased use of pulmonary angiography. Finally, an article on complications of percutaneous biliary drainage provokes some discussion of its value for routine preoperative use

The scale of craniofacial intervention lies between the fields of neuro-intervention and peripheral interventional for the main purpose to investigate, diagnose and treat the disease entities originating from or supplied by the external carotid arterial system. Patients are usually refered to the oral and maxillofacial surgery, plastic surgery and otolaryngeal surgery. Craniofacial intervention includes mainly the diagnosis and treatment with adjuvant embolization of high-flow vascular diseases, intra-arterial chemotherapy of malignant tumors, embolization of epistaxis, etc. At present, there is no consensus with regard to the diagnosis and treatment of some craniofacial diseases, therefore further investigation and discussion are needed.

People with a diagnosis of schizophrenia have significant social and functional difficulties. Social cognition was found to influences these outcomes and in recent years interventions targeting this domain were developed. This paper reviews the existing literature on social cognition interventions for people with a diagnosis of schizophrenia focussing on: i) comparing focussed (i.e. targeting only one social cognitive domain) and global interventions and ii) studies methodological quality. Systematic search was conducted on PubMed and PsycInfo. Studies were included if they were randomised control trials, participants had a diagnosis of schizophrenia or schizoaffective disorder, and the intervention targeted at least one out of four social cognition domains (i.e. theory of mind, affect recognition, social perception and attribution bias). All papers were assessed for methodological quality. Information on the intervention, control condition, study methodology and the main findings from each study were extracted and critically summarised. Data from 32 studies fulfilled the inclusion criteria, considering a total of 1440 participants. Taking part in social cognition interventions produced significant improvements in theory of mind and affect recognition compared to both passive and active control conditions. Results were less clear for social perception and attributional bias. Focussed and global interventions had similar results on outcomes. Overall study methodological quality was modest. There was very limited evidence showing that social cognitive intervention result in functional outcome improvement. The evidence considered suggests that social cognition interventions may be a valuable approach for people with a diagnosis of schizophrenia. However, evidence quality is limited by measure heterogeneity, modest study methodology and short follow-up periods. The findings point to a number of recommendations for future research, including measurement standardisation

Interventions to cope with alcohol abuse: integrative review

Fernanda Jorge Guimarães

2015-09-01

Full Text Available Alcohol is the most consumed drug in the world, which could generate social and health problems, affecting users, people living with them and the society in general. The aim was to identify the best evidence of interventions to reduce alcohol abuse. An integrative review of the literature, conducted on LILACS, CINAHL, PUBMED and SCOPUS, through the descriptors “intervention studies” and “alcoholism”. Nineteen articles were selected, most of them classified as two regarding level of evidence. They involved interventions with alcohol users, the most efficient were short interventions, internet-based interventions and counselling. Although cessation of alcohol use was not proved through the interventions, results point to a significant reduction in consumption, increase of the availability to change drinking habit and effective impact of short interventions when compared to usual treatments. Short interventions constitute the best interventions to reduce alcohol abuse.

What drives forex interventions? Evidence from the Brazilian Central Bank interventions on the BRL/USD market

Full Text Available In this paper we study what drives buy-side and sell-side probabilities of intervention by the Brazilian Central Bank (BCB on the USD/BRL spot market between 1999 and 2010. BCB’s forex interventions seem to be related to the exchange rate returns and volatility as well as to the spread between domestic and foreign interest rates. Lagged interventions also appear to have an effect on current interventions. Our findings suggest that the operation of the policymaker in the forex market may serve as a signaling of a possible coordination between BCB’s foreign and monetary policies along with the possibility of an unofficial adoption of an exchange rate band.

Patients are increasingly using online social networks (ie, social media) to connect with other patients and health care professionals—a trend called peer-to-peer health care. Because online social networks provide a means for health care professionals to communicate with patients, and for patients to communicate with each other, an opportunity exists to use social media as a modality to deliver behavioral interventions. Social media-delivered behavioral interventions have the potential to reduce the expense of behavioral interventions by eliminating visits, as well as increase our access to patients by becoming embedded in their social media feeds. Trials of online social network-delivered behavioral interventions have shown promise, but much is unknown about intervention development and methodology. In this paper, we discuss the process by which investigators can translate behavioral interventions for social media delivery. We present a model that describes the steps and decision points in this process, including the necessary training and reporting requirements. We also discuss issues pertinent to social media-delivered interventions, including cost, scalability, and privacy. Finally, we identify areas of research that are needed to optimize this emerging behavioral intervention modality. PMID:26825969

Are all interventions created equal? A multi-threat approach to tailoring stereotype threat interventions.

Shapiro, Jenessa R; Williams, Amy M; Hambarchyan, Mariam

2013-02-01

To date, stereotype threat interventions have been considered interchangeable. Across 4 experiments, the present research demonstrates that stereotype threat interventions need to be tailored to the specific form of experienced stereotype threat to be effective. The Multi-Threat Framework (Shapiro & Neuberg, 2007) distinguishes between group-as-target stereotype threats-concerns that a stereotype-relevant performance will reflect poorly on the abilities of one's group-and self-as-target stereotype threats-concerns that a stereotype-relevant performance will reflect poorly on one's own abilities. The present experiments explored Black college students' performance on diagnostic intelligence tests (Experiments 1 and 3) and women's interest (Experiment 2) and performance (Experiment 4) in science, technology, engineering, and math (STEM). Across the 4 experiments, participants were randomly assigned to experience either a group-as-target or self-as-target stereotype threat. Experiments 1 and 2 revealed that role model interventions were successful at protecting only against group-as-target stereotype threats, and Experiments 3 and 4 revealed that self-affirmation interventions were successful at protecting only against self-as-target stereotype threats. The present research provides an experimental test of the Multi-Threat Framework across different negatively stereotyped groups (Black students, female students), different negatively stereotyped domains (general intelligence, STEM), and different outcomes (test performance, career interest). This research suggests that interventions should address the range of possible stereotype threats to effectively protect individuals against these threats. Through an appreciation of the distinct forms of stereotype threats and the ways in which interventions work to reduce them, this research aims to facilitate a more complete understanding of stereotype threat.

Researchers often struggle with the gap between efficacy and effectiveness in clinical research. To bridge this gap, the Community Healthcare for Asthma Management and Prevention of Symptoms (CHAMPS) study adapted an efficacious, randomized controlled trial that resulted in evidence-based asthma interventions in community health centers. Children (aged 5-12 years; N = 590) with moderate to severe asthma were enrolled from 3 intervention and 3 geographically/capacity-matched control sites in high-risk, low-income communities located in Arizona, Michigan, and Puerto Rico. The asthma intervention was tailored to the participant's allergen sensitivity and exposure, and it comprised 4 visits over the course of 1 year. Study visits were documented and monitored prospectively via electronic data capture. Asthma symptoms and health care utilization were evaluated at baseline, and at 6 and 12 months. A total of 314 intervention children and 276 control children were enrolled in the study. Allergen sensitivity testing (96%) and home environmental assessments (89%) were performed on the majority of intervention children. Overall study activity completion (eg, intervention visits, clinical assessments) was 70%. Overall and individual site participant symptom days in the previous 4 weeks were significantly reduced compared with control findings (control, change of -2.28; intervention, change of -3.27; difference, -0.99; P asthma in these high-need populations.

To develop an intervention procedure for spelling difficulties and to verify the effectiveness of the intervention program in students with lower spelling performance. We developed an intervention program for spelling difficulties, according to the semiology of the errors. The program consisted of three modules totaling 16 sessions. The study included 40 students of the third to fifth grade of public elementary education of the city of Marilia (SP), of both genders, in aged of eight to 12 years old, being distributed in the following groups: GI (20 students with lower spelling performance) and GII (20 students with higher spelling performance). In situation of pre and post-testing, all groups were submitted to the Pro-Orthography. The results statistically analyzed showed that, in general, all groups had average of right that has higher in post-testing, reducing the types of errors second semiologycal classification, mainly related to natural spelling errors. However, the results also showed that the groups submitted to the intervention program showed better performance on spelling tests in relation to not submitted. The intervention program developed was effective once the groups submitted showed better performance on spelling tests in relation to not submitted. Therefore, the intervention program can help professionals in the Health and Education to minimize the problems related to spelling, giving students an intervention that is effective for the development of the spelling knowledge.

Radiological safety for the public during nuclear emergencies: application of intervention levels and derived intervention levels

International Nuclear Information System (INIS)

Thomas, G.; Kumar, K.S.

2006-01-01

Control of radiation exposures to the public following a major nuclear accident can be achieved through intervention by implementing countermeasures such as sheltering, iodine prophylaxis, evacuation, control of foodstuff, etc. Intervention levels (I.L.) are formulated such that exposure to individuals from all exposure pathways is well below the thresholds for deterministic effects, and risk of stochastic health effects to individuals and overall incidence of stochastic effects in the exposed population are minimized. It is also necessary to translate such I.L. into quantities, called derived intervention levels (D.I.L.) that can be measured. The I.L. followed in various countries for the recommended countermeasures cater to the exposure range of 1-50 mSv for sheltering, 10-500 mSv for evacuation, 30- 1000 mSv for iodine prophylaxis and 1-10 mSv for food control. The models used for these are based on conservative estimations assuming maximum dose delivered to the critical group for the pathway assumed. While the concept of upper dose level above which countermeasures is always justified to avoid deterministic effects, the lower range of dose levels have to be optimised based on various parameters as discussed in this paper. While arriving at the I.L., the question to be addressed is: How much (dose) risk should be averted by the intervention planned? Implementation of any countermeasure will result in some inconvenience/ limitation of resource/ disruption and consequently, a positive net benefit will justify the intervention. Sheltering may result in substantially less disruption than evacuation, but if the type of sheltering is not offering enough radiation shielding or ventilation protection, this may not result in significant reduction of exposure. It is to be ensured that deterministic effects are totally avoided and it is possible to define a safe threshold exposure and above which balancing risks and benefits is not applicable. While the dose limit for the

Full Text Available Background: In Uganda, health system challenges limit access to good quality healthcare and contribute to slow progress on malaria control. We developed a complex intervention (PRIME, which was designed to improve quality of care for malaria at public health centres. Objective: Responding to calls for increased transparency, we describe the PRIME intervention's design process, rationale, and final content and reflect on the choices and challenges encountered during the design of this complex intervention. Design: To develop the intervention, we followed a multistep approach, including the following: 1 formative research to identify intervention target areas and objectives; 2 prioritization of intervention components; 3 review of relevant evidence; 4 development of intervention components; 5 piloting and refinement of workshop modules; and 6 consolidation of the PRIME intervention theories of change to articulate why and how the intervention was hypothesized to produce desired outcomes. We aimed to develop an intervention that was evidence-based, grounded in theory, and appropriate for the study context; could be evaluated within a randomized controlled trial; and had the potential to be scaled up sustainably. Results: The process of developing the PRIME intervention package was lengthy and dynamic. The final intervention package consisted of four components: 1 training in fever case management and use of rapid diagnostic tests for malaria (mRDTs; 2 workshops in health centre management; 3 workshops in patient-centred services; and 4 provision of mRDTs and antimalarials when stocks ran low. Conclusions: The slow and iterative process of intervention design contrasted with the continually shifting study context. We highlight the considerations and choices made at each design stage, discussing elements we included and why, as well as those that were ultimately excluded.

Legal Permissibility of Unilateral Humanitarian Interventions

Directory of Open Access Journals (Sweden)

Petra Perisic

2013-03-01

Full Text Available The paper explores the status of unilateral humanitarian interventions in international law. The United Nations Charter prohibits the use of force, except in case of self-defense and the collective action authorized by the Security Council. The question is whether the non-existence of unilateral humanitarian intervention among these exceptions means that they are not in conformity with the Charter and if so, whether the right to such interventions exists as the part of customary law. The issue has become even more controversial after the adoption of the “responsibility to protect” principle. Findings of legal scholars on this issue differ significantly. This paper analyzes and interprets the Charter provisions in order to answer the question of compatibility of humanitarian interventions with the Charter and examines the state practice in order to conclude whether the customary law rule allowing the humanitarian intervention exists. The conclusion of the paper is that there is no evidence to support the contentions that interventions without the Security Council authorization are permissible, although there are elements which point to the possibility of the creation of customary law allowing them.

El año 2009 los peatones fueron involucrados en 27% de los accidentes de tránsito en el Perú. Este es un problema significativo para la salud pública del país, pues tiene repercusiones económicas importantes. En este artículo se revisa la evidencia disponible para algunas intervenciones implementadas en otros países y enfocadas a la prevención de los atropellos, las que podrían funcionar bien en Perú. De manera consistente, la implementación de intervenciones tales como el calmar el tráfico en áreas específicas a través de reductores de velocidad ("rompemuelles", minirotondas ("óvalos", mejor alumbramiento, calles unidireccionales, desvíos y bloqueos de las calles, tiene una fuerte evidencia en reducir las lesiones y fatalidades en los peatones.

Much of the food available from takeaways, pubs and restaurants particularly that sold by independent outlets, is unhealthy and its consumption is increasing. These food outlets are therefore important potential targets for interventions to improve diet and thus prevent diet related chronic diseases. Local authorities in England have been charged with delivering interventions to increase the provision of healthy food choices in independent outlets, but prior research shows that few such interventions have been rigorously developed or evaluated. We aimed to learn from the experiences of professionals delivering interventions in independent food outlets in England to identify the operational challenges and their suggestions for best practice. We used one-to-one semi-structured qualitative interviews to explore the views and experiences of professionals who were either employees of, or contracted by, a local authority to deliver interventions to increase the provision of healthier food choices in independent food outlets. Purposive sampling was used to recruit a sample which included men and women, from a range of professional roles, across different areas of England. Interviews were informed by a topic guide, and proceeded until no new themes emerged. Interviews were recorded, transcribed verbatim and analysed using the Framework method. We conducted 11 individual interviews. Participants focussed on independent takeaways and their unhealthy food offerings, and highlighted the advantages and disadvantages of intervention delivery methods, their evaluation and impact. The main barriers to implementation of interventions in independent takeaways were identified as limited funding and the difficulties of engaging the food outlet owner/manager. Engagement was thought to be facilitated by delivering intensive, interactive and tailored interventions, clear and specific information, and incentives, whilst accounting for practical, primarily financial, constraints of food

Can a Costly Intervention Be Cost-effective?

Foster, E. Michael; Jones, Damon

Objectives To examine the cost-effectiveness of the Fast Track intervention, a multi-year, multi-component intervention designed to reduce violence among at-risk children. A previous report documented the favorable effect of intervention on the highest-risk group of ninth-graders diagnosed with conduct disorder, as well as self-reported delinquency. The current report addressed the cost-effectiveness of the intervention for these measures of program impact. Design Costs of the intervention were estimated using program budgets. Incremental cost-effectiveness ratios were computed to determine the cost per unit of improvement in the 3 outcomes measured in the 10th year of the study. Results Examination of the total sample showed that the intervention was not cost-effective at likely levels of policymakers' willingness to pay for the key outcomes. Subsequent analysis of those most at risk, however, showed that the intervention likely was cost-effective given specified willingness-to-pay criteria. Conclusions Results indicate that the intervention is cost-effective for the children at highest risk. From a policy standpoint, this finding is encouraging because such children are likely to generate higher costs for society over their lifetimes. However, substantial barriers to cost-effectiveness remain, such as the ability to effectively identify and recruit such higher-risk children in future implementations. PMID:17088509

Interventional Cardiology for Congenital Heart Disease.

Congenital heart interventions are now replacing surgical palliation and correction in an evolving number of congenital heart defects. Right ventricular outflow tract and ductus arteriosus stenting have demonstrated favorable outcomes compared to surgical systemic to pulmonary artery shunting, and it is likely surgical pulmonary valve replacement will become an uncommon procedure within the next decade, mirroring current practices in the treatment of atrial septal defects. Challenges remain, including the lack of device design focused on smaller infants and the inevitable consequences of somatic growth. Increasing parental and physician expectancy has inevitably lead to higher risk interventions on smaller infants and appreciation of the consequences of these interventions on departmental outcome data needs to be considered. Registry data evaluating congenital heart interventions remain less robust than surgical registries, leading to a lack of insight into the longer-term consequences of our interventions. Increasing collaboration with surgical colleagues has not been met with necessary development of dedicated equipment for hybrid interventions aimed at minimizing the longer-term consequences of scar to the heart. Therefore, great challenges remain to ensure children and adults with congenital heart disease continue to benefit from an exponential growth in minimally invasive interventions and technology. This can only be achieved through a concerted collaborative approach from physicians, industry, academia and regulatory bodies supporting great innovators to continue the philosophy of thinking beyond the limits that has been the foundation of our specialty for the past 50 years.

Nonpathologizing trauma interventions in abnormal psychology courses.

Hoover, Stephanie M; Luchner, Andrew F; Pickett, Rachel F

2016-01-01

Because abnormal psychology courses presuppose a focus on pathological human functioning, nonpathologizing interventions within these classes are particularly powerful and can reach survivors, bystanders, and perpetrators. Interventions are needed to improve the social response to trauma on college campuses. By applying psychodynamic and feminist multicultural theory, instructors can deliver nonpathologizing interventions about trauma and trauma response within these classes. We recommend class-based interventions with the following aims: (a) intentionally using nonpathologizing language, (b) normalizing trauma responses, (c) subjectively defining trauma, (d) challenging secondary victimization, and (e) questioning the delineation of abnormal and normal. The recommendations promote implications for instructor self-reflection, therapy interventions, and future research.

Based on IAEA SS109 and ICRP63, intervention levels and action levels are derived using cost-benefit approach method. Intervention levels are optimized so that the net benefit from protective measures will be maximized. Evacuation, sheltering, relocation, permanent resettlement, administration of stable iodine and food restriction are included in protective measures. Intervention levels are calculated using site specific parameters in Korea. As a results of calculation, general intervention levels are similar to IAEA recommendation and action levels for food restriction are a little higher than IAEA recommendation and Japan guide. Guide on intervention levels in Korea is also suggested based on the calculated results.

The issue of childhood overweight and obesity has become a global public health crisis. School-based interventions have been developed and implemented to combat this growing concern. The purpose of this review is to compare and contrast U.S. and international school-based obesity prevention interventions and highlight efficacious strategies. A systematic literature review was conducted utilizing five relevant databases. Inclusion criteria were: (1) primary research; (2) overweight or obesity prevention interventions; (3) school-based; (4) studies published between 1 January 2002 through 31 December 2013; (5) published in the English language; (6) child-based interventions, which could include parents; and (7) studies that reported outcome data. A total of 20 interventions met the inclusion criteria. Ten interventions each were implemented in the U.S. and internationally. International interventions only targeted elementary-aged students, were less likely to target low-income populations, and were less likely to be implemented for two or more years in duration. However, they were more likely to integrate an environmental component when compared to U.S. interventions. Interventions implemented in the U.S. and internationally resulted in successful outcomes, including positive changes in student BMI. Yet, varying approaches were used to achieve success, reinforcing the fact that a one-size-fits-all approach is not necessary to impact childhood obesity. However, building on successful interventions, future school-based obesity prevention interventions should integrate culturally specific intervention strategies, aim to incorporate an environmental component, and include parents whenever possible. Consideration should be given to the potential impact of long-term, frequent dosage interventions, and subsequent follow-up should be given attention to determine long-term efficacy.

Abstract Early intervention for potentially serious disorder is a fundamental feature of healthcare across the spectrum of physical illness. It has been a major factor in the reductions in morbidity and mortality that have been achieved in some of the non-communicable diseases, notably cancer and cardiovascular disease. Over the past two decades, an international collaborative effort has been mounted to build the evidence and the capacity for early intervention in the psychotic disorders, notably schizophrenia, where for so long deep pessimism had reigned. The origins and rapid development of early intervention in psychosis are described from a personal and Australian perspective. This uniquely evidence-informed, evidence-building and cost-effective reform provides a blueprint and launch pad to radically change the wider landscape of mental health care and dissolve many of the barriers that have constrained progress for so long.

The extracorporeal shock wave lithotriptor is an excellent example of modern technology that is successfully applied to solve a medical problem. ESWL is rapidly becoming the standard method for treating patients with persistent urinary tract stones. The extracorporeal shock wave lithotriptor represents an enormous advance in the treatment of renal calculi, however, the machine is not infallible. Presently, a slightly more than 5% of the patients require additional interventional radiographic procedures to facilitate passage of their stones. The authors' data indicates that large stones (≥ 2.5 cm) are more likely to need interventional procedures. As more large stones are treated by ESWL, the need for interventional radiographic procedures will increase. This necessity has led to the development of new techniques, such as the lithocenosis catheter and waterpik procedure, to relieve the obstructed urinary tract by removal of the stone fragments

Minimally invasive interventions are rapidly replacing invasive surgical procedures for the most prevalent human disease conditions. X-ray image-guided interventions carried out using the insertion and navigation of catheters through the vasculature are increasing in number and sophistication. In this article, we offer our vision for the future of this dynamic field of endovascular image-guided interventions in the form of predictions about (1) improvements in high-resolution detectors for more accurate guidance, (2) the implementation of high-resolution region of interest computed tomography for evaluation and planning, (3) the implementation of dose tracking systems to control patient radiation risk, (4) the development of increasingly sophisticated interventional devices, (5) the use of quantitative treatment planning with patient-specific computer fluid dynamic simulations, and (6) the new expanding role of the medical physicist. We discuss how we envision our predictions will come to fruition and result in the universal goal of improved patient care.

During the past ten years, an increasing number of controlled studies have assessed the potential rehabilitative effects of music-based interventions, such as music listening, singing, or playing an instrument, in several neurological diseases. Although the number of studies and extent of available evidence is greatest in stroke and dementia, there is also evidence for the effects of music-based interventions on supporting cognition, motor function, or emotional wellbeing in people with Parkinson's disease, epilepsy, or multiple sclerosis. Music-based interventions can affect divergent functions such as motor performance, speech, or cognition in these patient groups. However, the psychological effects and neurobiological mechanisms underlying the effects of music interventions are likely to share common neural systems for reward, arousal, affect regulation, learning, and activity-driven plasticity. Although further controlled studies are needed to establish the efficacy of music in neurological recovery, music-based interventions are emerging as promising rehabilitation strategies.

Supporting Families through Early Intervention

Roy McConkey

Full Text Available Internationally early intervention programmes for infants and preschoolers with disabilities have proved to be remarkably successful. In many countries, they began with teachers for visually impaired or hearing impaired children visiting the family home to teach parents how they could overcome the child's impairments. The logic of early intervention was inequitable. For example, the sooner children with visual impairments learnt to be independently mobile, then the greater their potential to learn and to kad an ordinary life. In time, this philosophy was extended to children with neurological and developmental delays, such as mental retardation, although success could be variable. In part, many different factors contributed to this variability: the form the interventions took, the extent of family involvement in the intervention and the lack of sensitivity of the measures used to assess a child's progress, to name but three. Perhaps the most extensive and intensive Early intervention schemes have been in the United States with their Head Start programmes. They were aimed at promoting the educational potential of preschoolers from deprived socio - economic backgrounds. Although the first phase of programmes had varying success, those in the second phase yielded impressive results which were mainly attributed to a greater focus on parental participation and links forged with the school system. Recently in developing countries, priority has been given to establishing early intervention as a means of creating new styles of family-based and community-based service in these countries in contrast to the hospital or institutional-services that were a legacy from a previous generation. Although formal evaluations are largely lacking, informal reports have been broadly enthusiastic. In sum, early intervention is no longer a new approach to developmental disabilities. It is an approach of proven effectiveness with children who have different impairments

Community interventions for cardiovascular disease.

Review of the community-based CVD intervention programs suggests that a number of components have been successful using varying methods and materials for CVD risk reduction. It should be noted, however, that in multi-intervention programs it is often difficult to determine which components of the intervention were responsible for the overall success of the study. The community-based approach to CVD prevention is generalizable, cost-effective (because of the use of mass communication methods), and has the potential for modifying the environment and influencing health policies. Based on the experiences and successes of a number of community projects, recommendations have been proposed for developing future programs. Although they are not totally comprehensive, it has been suggested that a community-based intervention program should consider the following recommendations: 1) An understanding of the community: the needs and priorities of the community should be assessed, and close collaboration with individuals from the community, including community leaders, opinion leaders, community health care providers, and community organizations from various sectors of the community, should be consulted. Efforts should be focused on underserved and vulnerable populations. 2) Inclusion of community activities: these activities should be integrated within the context of the community environment, including primary health care services, voluntary organizations, grocery stores, restaurants, work sites, schools, and local media. 3) Inclusion mass media messages: the mass media can provide information and reinforcement of the behavior change. 4) Develop cost-effective interventions to assure that the community is exposed to an effective dose of the intervention. 5) Work with community organizations to help change social and physical environments to make them more conducive to health and healthy life-styles changes. 6) Develop a reliable monitoring and evaluation system: monitor the

Psychoneuroimmunology-based interventions are used to attenuated disease progression and/or side effects of pharmacological treatment. This systematic review evaluates the different therapeutic and/or clinical psychoneuroimmunology-based interventions associated to both psychological, neuroendocrine and immunological variables. The review was conducted for all English, Portuguese and Spanish language articles published between 2005 and 2015. Independent investigators analyzed 42 studies concerning human psychoneuroimmunology-based interventions. Decreased levels of cortisol, epinephrine and norepinephrine (stress-related hormones) were associated to interventions like yoga, meditation, tai chi, acupuncture, mindfulness, religious/spiritual practices, cognitive behavior therapy, coping and physical exercises. Moreover, those interventions were also associated to reductions in inflammatory processes and levels of pro-inflammatory cytokines in cancer, HIV, depression, anxiety, wound healing, sleep disorder, cardiovascular diseases and fibromyalgia. Despite the associations between PNI variables and clinical/therapeutic interventions, only one study evidenced significant effects on a disease progression.

The rapidly growing body of research regarding the use of meditation interventions in chronic disease presents an opportunity to compare outcomes based on intervention content. For this review, meditation interventions were described as those interventions delivered to persons with chronic disease where sitting meditation was the main or only content of the intervention with or without the addition of mindful movement. This systematic review identified 45 individual research studies that examined meditations effect on levels of anxiety, depression, and chronic disease symptoms in persons with chronic disease. Individual studies were assessed based on interventional content, the consistency with which interventions were applied, and the research quality. This study identified seven categories of meditation interventions based on the meditation skills and mindful movement practices that were included in the intervention. Overall, half of the interventions had clearly defined and specific meditation interventions (25/45) and half of the studies were conducted using randomized control trials (24/45). © The Author(s) 2015.

Full Text Available Introduction: The world's population is often assailed by crises of various orders. Disasters caused by nature and by humans themselves also impact on people's mental health. Psychological crises, such as suicide attempts, represent a growing problem in mental health. When faced with such scenarios, specific strategies of crisis intervention are both appropriate and necessary. Objective: To conduct a systematic review of the literature dealing with online psychological crisis intervention, describing and discussing their operational design, specific characteristics and applications. Method: A systematic review of literature indexed on the PubMed, PsycINFO, and SciELO databases identified by searches conducted from January to June of 2014. Results: The searches identified 17 empirical studies about online crisis interventions which were reviewed. Three crisis contexts emerged: 1 disasters, 2 risk/prevention of suicide, and 3 trauma. Eleven different intervention programs were described and the predominant treatment approach was cognitive behavioral therapy. The results showed that research into online psychological crisis intervention has been conducted in several different countries, especially the Netherlands and Australia, and that the users of these tools benefit from them. Conclusion: Online crisis interventions have been developed and researched in many countries around the world. In Brazil, there is still a lack of investment and research in this area.

Abduction, ASP and Open Logic Programs

Open logic programs and open entailment have been recently proposed as an abstract framework for the verification of incomplete specifications based upon normal logic programs and the stable model semantics. There are obvious analogies between open predicates and abducible predicates. However, despite superficial similarities, there are features of open programs that have no immediate counterpart in the framework of abduction and viceversa. Similarly, open programs cannot be immediately simul...

Full Text Available Ultrasound (US is often used to guide various interventional procedures in the genitourinary (GU tract because it can provide real-time imaging without any radiation hazard. Moreover, US can clearly visualize the pathway of an aspiration or biopsy needle to ensure the safety of the intervention. US guidance also helps clinicians to access lesions via the transabdominal, transhepatic, transvaginal, transrectal, and transperineal routes. Hence, US-guided procedures are useful for radiologists who wish to perform GU interventions. However, US-guided procedures and interventions are difficult for beginners because they involve a steep initial learning curve. The purpose of this review is to describe the basic principles and techniques of US-guided GU interventions.

Interventional radiology is a relatively new speciality and may be referred to as 'image-guided surgery without a scalpel.' Training and accreditation bodies regard interventional radiology training as being 'different' from general radiology because of the additional need for dexterity and clinical acumen. Due to the multidimensional role of an interventional radiologist, a practitioner in this discipline must have a number of the competencies of anesthetists, surgeons, and radiologists. The attributes required of an interventional radiologist are akin to those required of a surgeon. This paper gives an overview of the skills required to be a competent interventional radiologist along with a succinct introduction to methods of assessment of technical and non-technical skills.

2011-01-01

This paper's objective is to apply Intervention Mapping, a planning process for the systematic development of theory- and evidence-based health promotion interventions, to the development of interventions to promote energy conservation behavior. Intervention Mapping (IM) consists of six steps: needs assessment, program objectives, methods and applications, program development, planning for program implementation, and planning for program evaluation. Examples from the energy conservation field are provided to illustrate the activities associated with these steps. It is concluded that applying IM in the energy conservation field may help the development of effective behavior change interventions, and thus develop a domain specific knowledge-base for effective intervention design. - Highlights: → Intervention Mapping (IM) is a planning process for developing evidence-based interventions.→ IM takes a problem-driven rather than theory-driven approach. → IM can be applied to the promotion of energy-conservation in a multilevel approach. → IM helps identifying determinants of behaviors and environmental conditions. → IM helps selecting appropriate theory-based methods and practical applications.

Obesity prevention is an international public health priority. The prevalence of obesity and overweight is increasing in child populations throughout the world, impacting on short and long-term health. Obesity prevention strategies for children can change behaviour but efficacy in terms of preventing obesity remains poorly understood. To assess the effectiveness of interventions designed to prevent obesity in childhood through diet, physical activity and/or lifestyle and social support. MEDLINE, PsycINFO, EMBASE, CINAHL and CENTRAL were searched from 1990 to February 2005. Non-English language papers were included and experts contacted. Randomised controlled trials and controlled clinical trials with minimum duration twelve weeks. Two reviewers independently extracted data and assessed study quality. Twenty-two studies were included; ten long-term (at least 12 months) and twelve short-term (12 weeks to 12 months). Nineteen were school/preschool-based interventions, one was a community-based intervention targeting low-income families, and two were family-based interventions targeting non-obese children of obese or overweight parents. Six of the ten long-term studies combined dietary education and physical activity interventions; five resulted in no difference in overweight status between groups and one resulted in improvements for girls receiving the intervention, but not boys. Two studies focused on physical activity alone. Of these, a multi-media approach appeared to be effective in preventing obesity. Two studies focused on nutrition education alone, but neither were effective in preventing obesity. Four of the twelve short-term studies focused on interventions to increase physical activity levels, and two of these studies resulted in minor reductions in overweight status in favour of the intervention. The other eight studies combined advice on diet and physical activity, but none had a significant impact. The studies were heterogeneous in terms of study design

Results from clinical trials indicate that Internet-based psychological pain interventions are effective in treating chronic pain. However, little is known about patients' acceptance of these programs and how to positively influence patients' intention to engage in them. Therefore, the present study aimed (1) to assess patients' acceptance of Internet-based interventions, and (2) to examine whether patients' acceptance can be increased by an acceptance facilitating intervention. A total of 104 patients with chronic pain from 2 pain units were randomly allocated to an intervention group (IG) and a no-intervention control group (CG). The IG was shown a short informational video about Internet-based psychological pain interventions before receiving a questionnaire on patients' acceptance of Internet-based psychological pain interventions and predictors of acceptance (performance expectancy, effort expectancy, social influence, facilitating conditions, Internet usage, and Internet anxiety). The CG filled out the questionnaire immediately. Patients' acceptance was measured with a 4-item scale (sum score ranging from 4 to 20). Baseline acceptance of Internet-based interventions was reported as low (sum-score:4-9) by 53.8%, moderate (10 to 15) by 42.3%, and high (16 to 20) by 3.9% of the patients with chronic pain in the CG. The IG showed a significantly higher acceptance (M = 12.17, SD = 4.22) than the CG (M = 8.94, SD = 3.71) with a standardized mean difference of d = 0.81 (95% CI, 0.41, 1.21). All predictor variables were significantly improved in the IG compared with the CG, except for Internet usage. Patients with chronic pain display a relatively low acceptance of Internet-based psychological pain interventions, which can be substantially increased by a short informational video.

Using intervention mapping to deconstruct cognitive work hardening: a return-to-work intervention for people with depression.

Wisenthal, Adeena; Krupa, Terry

2014-12-12

Mental health related work disability leaves are increasing at alarming rates with depression emerging as the most common mental disorder in the workforce. Treatments are available to alleviate depressive symptoms and associated functional impacts; however, they are not specifically aimed at preparing people to return to work. Cognitive work hardening (CWH) is a novel intervention that addresses this gap in the health care system. This paper presents a theoretical analysis of the components and underlying mechanisms of CWH using Intervention Mapping (IM) as a tool to deconstruct its elements. The cognitive sequelae of depression and their relevance to return-to-work (RTW) are examined together with interpersonal skills and other work-related competencies that affect work ability. IM, a tool typically used to create programs, is used to deconstruct an existing program, namely CWH, into its component parts and link them to theories and models in the literature. CWH has been deconstructed into intervention elements which are linked to program performance objectives through underlying theoretical models. In this way, linkages are made between tools and materials of the intervention and the overall program objective of 'successful RTW for people with depression'. An empirical study of the efficacy of CWH is currently underway which should provide added insight and understanding into this intervention. The application of IM to CWH illustrates the theoretical underpinnings of the treatment intervention and assists with better understanding the linkage between intervention elements and intervention objective. Applying IM to deconstruct an existing program (rather than create a program) presents an alternate application of the IM tool which can have implications for other programs in terms of enhancing understanding, grounding in theoretical foundations, communicating program design, and establishing a basis for program evaluation and improvement.

Full Text Available Humanitarian intervention in Kosovo did not happen by any geopolitical interest, but simply by an entirely humanitarian character which is closely connected with democratic principles, human rights, and the lack of moral order. Except for damages, massacres and destruction by fire of very sophisticated military artillery, Serbian army and police have forced with violence more than thousands of Kosovo Albanians to leave their home (Pllana, 2010, 241. With humanitarian intervention, NATO had shown it was ready to defend universal human values as the fundamental principle of humanity (free life.

Music intervention as system: reversing hyper systemising in autism spectrum disorders to the comprehension of music as intervention.

Science.gov (United States)

Jaschke, Artur C

2014-01-01

This paper seeks to combine the notion of the Empathising-Systemising (E-S) theory and the resulting twist from the executive dysfunction theory in autism spectrum conditions (ASC) in light of music intervention as system. To achieve these points it will be important to re-visit, nonetheless briefly, the above mentioned theories and re-define music intervention in the light of these. Furthermore there is the need to adjust the executive dysfunction theory to a theory of dysfunctioning executive functions. These notions will create a different understanding of music intervention in this context, allowing the development of future and existing music intervention programs applied clinically. These applications will evolve around a structuralised approach to music intervention as system, proposing five consecutive systems. It will therefore argue the aspects of expanding existing theories in ASC together with the call for generalised interventions to better assess autism from a theoretical point of view. Theories have to be updated in a time of fast and ever-changing development. Copyright © 2013 Elsevier Ltd. All rights reserved.

Full Text Available Background Since the 70s there was a proliferation of intervention programs for batterers; however the results remain controversial. Objectives This study aims to analyse the literature published between the years of 2000 and 2013 about the effectiveness of the intervention with batterers. Methods A review of papers about intervention with batterers published during this period (2000-2013 was conducted. Social sciences databases were checked. Papers about programs for a specific public or programs with a broad intervention focus, and with female and homosexual offenders were excluded. Results Thirty-six studies that described 37 intervention programs fulfilled the inclusion criteria. In general, the analysed programs adopted a group format (70.3% and a cognitive-behavioural (56.8% or psychoeducational (18.9% intervention model (32.4% assumed to adopt a Duluth model. Concerning the effectiveness, results showed success rates of 39.4%-97%, dropout rates of 10%-58% and recidivism rates of 0%-65.9%. Discussion The effectiveness of intervention with batterers remains controversial, which seems to be due to the different methodologies used in the studies. Despite the inconsistencies, programs for perpetrators are an important way to reduce intimate partner violence recidivism.

The purpose of this study is to evaluate the radiological findings and effectiveness of radiological interventions in patients with iatrogenic vascular injuries. We analyzed 50 patients with iatrogenic vascular injuries treated with radiological intervention. The causes of injuries were surgery (n=20), cardiovascular intervention (n=15), non-cardiovascular radiological intervention (n=14), and endoscopic intervention (n=1). The injury had resulted in hemorrhage in 35 cases. The iliac and/or femoral, hepatic, and renal vessels were commonly injured. Angiography, ultrasonography with Doppler examination, CT, and CT angiography were performed to diagnose vascular injuries and guide the radiological intervention. The mean follow-up period was 23 months and in 16 cases was more than one year. the major radiological findings were extravasation, pseudoaneurysm, arteriovenous shunt, or vascular obstruction. To control these lesions, radiological interventions such as embolization (n=36), local urokinase administration, stent insertion, foreign body removal, ultrasonography-guided compression, or stent-graft insertion were performed. The clinical problems were immediately controlled by the single trials of radiological interventions and did not recur in 40 cases (80%). Radiological examinations and interventions are useful in cases with iatrogenic vascular injuries. (author). 14 refs., 4 figs

The integration of diagnostic and therapeutic procedures by MRI is based on the combination of excellent morphologic and functional imaging. The spectrum of MR-guided interventions includes biopsies, thermal ablation procedures, vascular applications, and intraoperative MRI. In all these applications, different scientific groups have obtained convincing results in basic developments as well as in clinical use. Interventional MRI (iMRI) is expected to attain an important role in interventional radiology, minimal invasive therapy, and monitoring of surgical procedures.

Linsenmaier, U.; Pfeifer, K.J.; Reiser, M.

2002-01-01

Purpose: Development of a save and effective protocol for analgosedation of patients undergoing painful interventional procedures. Material and Methods: In a prospective trial a consecutive series of 72 adult patients underwent analgosedation during painful interventions. A radiologist performed the analgosedation, the patients received a combination of a shortly effective piperidine derivative (Alfentanil [Rapifen trademark ]; 7.5-15 μg/kg body weight) and Benzodiazepine (midazolam [Dormicum trademark ]; 20 μg/kg body weight). After pre-procedure oxygenation patients were continuously monitored. Pain and discomfort were scored using an established visual-analog pain score (0-10). A control group (n=24) had received midazolam, pentazocine or fentanyl according to the study protocol. Results: All procedures could be carried out by an interventional radiologist and a nurse and/or technologist only. In 69/72 cases adequate analgosedation could be achieved. Injection of alfentanil was titrated, with a rapid onset and short acting effect of the analgesia. Patients reported an average pain score of 2.6 vs. 4.5 in the control group. Over 55% experienced no or mild pain (score 0-3), in the control group only 8% reached this level. Conclusion: A combination of shortly effective alfentanil and midazolam allows interventional radiologists to perform major procedures alone under effective analgosedation. This medication scheme is superior to the medication upon demand. (orig.) [de

Motor vehicle crashes are the leading cause of death for U.S. Latinos aged 1 to 35 years. Restraint use is an effective means of prevention of motor vehicle crash injury. Effective interventions to raise restraint use include the following: legislation, law enforcement, education, and equipment distribution. The effects of law enforcement interventions in Latino immigrant communities are understudied. We measured the community-level effect of a combined intervention that included warnings and citations phase enforcement in Latino communities. We designed and implemented in two of three Latino-majority communities a multicomponent intervention consisting of a community awareness campaign, restraint use education with equipment distribution, and a two-staged law enforcement intervention. Restraint use observations were conducted in all three communities at baseline, after the warnings phase and again after the citations phase of the intervention were completed. The combined intervention of community awareness, education, child passenger restraint distribution, and law enforcement focused on educational traffic stops with incentives and warnings was associated with a significant increase in both driver and child passenger restraint use in one intervention community, but only driver restraint increased to a level of significance in the other intervention community; significant increase was also noted among nonintervention drivers. The citations phase of the intervention did not result in a significant increase in restraint use and was complicated by interruptions due to unlicensed drivers. The combined effort of community awareness, education, equipment distribution and law enforcement intervention that included incentives and warnings may be effective at increasing seat belt use in Latino communities without the need for citations.

Combining Compile-Time and Run-Time Parallelization

Directory of Open Access Journals (Sweden)

Sungdo Moon

1999-01-01

Full Text Available This paper demonstrates that significant improvements to automatic parallelization technology require that existing systems be extended in two ways: (1 they must combine high‐quality compile‐time analysis with low‐cost run‐time testing; and (2 they must take control flow into account during analysis. We support this claim with the results of an experiment that measures the safety of parallelization at run time for loops left unparallelized by the Stanford SUIF compiler’s automatic parallelization system. We present results of measurements on programs from two benchmark suites – SPECFP95 and NAS sample benchmarks – which identify inherently parallel loops in these programs that are missed by the compiler. We characterize remaining parallelization opportunities, and find that most of the loops require run‐time testing, analysis of control flow, or some combination of the two. We present a new compile‐time analysis technique that can be used to parallelize most of these remaining loops. This technique is designed to not only improve the results of compile‐time parallelization, but also to produce low‐cost, directed run‐time tests that allow the system to defer binding of parallelization until run‐time when safety cannot be proven statically. We call this approach predicated array data‐flow analysis. We augment array data‐flow analysis, which the compiler uses to identify independent and privatizable arrays, by associating predicates with array data‐flow values. Predicated array data‐flow analysis allows the compiler to derive “optimistic” data‐flow values guarded by predicates; these predicates can be used to derive a run‐time test guaranteeing the safety of parallelization.

The explicit use of theory in research helps expand the knowledge base. Theories and models have been used extensively in HIV-prevention research and in interventions for preventing sexually transmitted infections (STIs). The health behavior field uses many theories or models of change. However, many educational interventions addressing contraception have no explicit theoretical base. To review randomized controlled trials (RCTs) that tested a theoretical approach to inform contraceptive choice and encourage or improve contraceptive use. To 1 November 2016, we searched for trials that tested a theory-based intervention for improving contraceptive use in PubMed, CENTRAL, POPLINE, Web of Science, ClinicalTrials.gov, and ICTRP. For the initial review, we wrote to investigators to find other trials. Included trials tested a theory-based intervention for improving contraceptive use. Interventions addressed the use of one or more methods for contraception. The reports provided evidence that the intervention was based on a specific theory or model. The primary outcomes were pregnancy and contraceptive choice or use. We assessed titles and abstracts identified during the searches. One author extracted and entered the data into Review Manager; a second author verified accuracy. We examined studies for methodological quality.For unadjusted dichotomous outcomes, we calculated the Mantel-Haenszel odds ratio (OR) with 95% confidence interval (CI). Cluster randomized trials used various methods of accounting for the clustering, such as multilevel modeling. Most reports did not provide information to calculate the effective sample size. Therefore, we presented the results as reported by the investigators. We did not conduct meta-analysis due to varied interventions and outcome measures. We included 10 new trials for a total of 25. Five were conducted outside the USA. Fifteen randomly assigned individuals and 10 randomized clusters. This section focuses on nine trials with high or

The aim of the study was to determine whether operant conditioning (OC) or systematic desensitization (SysD) intervention resulted in more improvements in dietary variety/intake, and more reductions in difficult mealtime behaviors. Children 2 to 6 years with autism spectrum disorder or with a nonmedically complex history were recruited. Feeding difficulties were confirmed based on clinical assessment. Participants were randomized to receive 10 OC or SysD sessions (parents could opt for intervention once per week, or intensively within a week). Immersive parent education was delivered across both arms. A 3-month review was provided to measure outcomes postintervention. In total, 68 participants (87%) completed the study. There were no significant differences in outcome measures between the OC and SysD intervention groups from baseline to 3-month review. When the data were combined across both groups, however, significant improvements in primary outcome measures were observed (P education, these 2 intervention approaches are effective. Further research is required in exploring these interventions across other subgroups, and examining outcomes for longer periods.

Linear Model for Optimal Distributed Generation Size Predication

Directory of Open Access Journals (Sweden)

Ahmed Al Ameri

2017-01-01

Full Text Available This article presents a linear model predicting optimal size of Distributed Generation (DG that addresses the minimum power loss. This method is based fundamentally on strong coupling between active power and voltage angle as well as between reactive power and voltage magnitudes. This paper proposes simplified method to calculate the total power losses in electrical grid for different distributed generation sizes and locations. The method has been implemented and tested on several IEEE bus test systems. The results show that the proposed method is capable of predicting approximate optimal size of DG when compared with precision calculations. The method that linearizes a complex model showed a good result, which can actually reduce processing time required. The acceptable accuracy with less time and memory required can help the grid operator to assess power system integrated within large-scale distribution generation.

René García Roche

2016-03-01

Full Text Available Background: aging-associated diseases contribute to morbidity and mortality in the population; therefore, it is necessary to develop intervention strategies to prevent and/or minimize their consequences. Objectives: to evaluate the effectiveness of a cognitive-behavioral intervention aimed at older hypertensive patients treated in primary care in Cardenas and Santiago de Cuba municipalities during 2011-2013. Methods: an intervention study of older adults with hypertension was conducted in two municipalities: Santiago de Cuba and Cárdenas. The intervention group was composed of 399 older patients living in the catchment areas of the Carlos Juan Finlay and Héroes del Moncada polyclinics while the control group included 377 older adults served by the Julian Grimau and Jose Antonio Echeverría polyclinics. The intervention consisted of a systematic strategy to increase knowledge of the disease in order to change lifestyles. Results: in the intervention group, there were more patients with sufficient knowledge of the disease (OR: 1.82, greater control of hypertension (OR: 1.51 and better adherence to treatment (OR: 1.70. By modeling the explanatory variables with hypertension control, being in the intervention group (OR: 0.695 and adhering to treatment (OR: 0.543 were found to be health protective factors. Conclusion: the congnitive-behavioral intervention for older adults treated in primary care of the municipalities studied was effective in improving blood pressure control since it contributed to a greater adherence to treatment.

In defense of prenatal genetic interventions.

Science.gov (United States)

Murphy, Timothy F

2014-09-01

Jürgen Habermas has argued against prenatal genetic interventions used to influence traits on the grounds that only biogenetic contingency in the conception of children preserves the conditions that make the presumption of moral equality possible. This argument fails for a number of reasons. The contingency that Habermas points to as the condition of moral equality is an artifact of evolutionary contingency and not inviolable in itself. Moreover, as a precedent for genetic interventions, parents and society already affect children's traits, which is to say there is moral precedent for influencing the traits of descendants. A veil-of-ignorance methodology can also be used to justify prenatal interventions through its method of advance consent and its preservation of the contingency of human identities in a moral sense. In any case, the selection of children's traits does not undermine the prospects of authoring a life since their future remains just as contingent morally as if no trait had been selected. Ironically, the prospect of preserving human beings as they are--to counteract genetic drift--might even require interventions to preserve the ability to author a life in a moral sense. In light of these analyses, Habermas' concerns about prenatal genetic interventions cannot succeed as objections to their practice as a matter of principle; the merits of these interventions must be evaluated individually. © 2012 John Wiley & Sons Ltd.

Recent advances in pediatric interventional cardiology.

Kim, Seong-Ho

2017-08-01

During the last 10 years, there have been major technological achievements in pediatric interventional cardiology. In addition, there have been several advances in cardiac imaging, especially in 3-dimensional imaging of echocardiography, computed tomography, magnetic resonance imaging, and cineangiography. Therefore, more types of congenital heart diseases can be treated in the cardiac catheter laboratory today than ever before. Furthermore, lesions previously considered resistant to interventional therapies can now be managed with high success rates. The hybrid approach has enabled the overcoming of limitations inherent to percutaneous access, expanding the application of endovascular therapies as adjunct to surgical interventions to improve patient outcomes and minimize invasiveness. Percutaneous pulmonary valve implantation has become a successful alternative therapy. However, most of the current recommendations about pediatric cardiac interventions (including class I recommendations) refer to off-label use of devices, because it is difficult to study the safety and efficacy of catheterization and transcatheter therapy in pediatric cardiac patients. This difficulty arises from the challenge of identifying a control population and the relatively small number of pediatric patients with congenital heart disease. Nevertheless, the pediatric interventional cardiology community has continued to develop less invasive solutions for congenital heart defects to minimize the need for open heart surgery and optimize overall outcomes. In this review, various interventional procedures in patients with congenital heart disease are explored.

Imaging in percutaneous musculoskeletal interventions

Gangi, Afshin; Guth, Stephane; Guermazi, Ali

2009-01-01

This is one of the first books to deal specifically with imaging in percutaneous musculoskeletal interventions. The use of different imaging modalities during these procedures is well described. In the first chapter, the basic procedures and different guidance techniques are presented and discussed. The ensuing chapters describe in exhaustive detail the abilities and uses of imaging in guiding procedures ranging from biopsy and joint injection to management of pain and tumors. These procedures are extensively documented in adults as well as in the pediatric population. The third part of the book describes the different indications for vascular interventions in musculoskeletal lesions. The final chapter focuses on ultrasound-guided interventions, as they are more common and tend to be fashionable. The book is well illustrated with carefully chosen and technically excellent images. Each of the 18 chapters is written by an expert of international repute, making this book the most current and complete treatment of the subject available. It should be of great interest to interventional radiologists and also musculoskeletal and general radiologists. (orig.)

CT-guided interventions in children

In pediatric CT-guided interventions specific features have to be taken into account. Due to a lack of cooperation or limited ability to cooperate, procedures are often performed using analgosedation or general anesthesia. To provide radiation protection, justified indication for CT-guided intervention is necessary and sonography and MRI are to be preferred whenever possible. CT examinations also need to be dose-adapted with sequential scanning and a tube voltage and tube current reduction compared to pediatric diagnostic CT studies must be ensured. Gonad shields are recommended for male patients. Biopsy device selection depends on the assumed tumor entity since histology and also immunohistochemical, molecular pathological and cytogenetical analysis are necessary to differentiate pediatric tumors (small, round, blue cell tumors). In addition to diagnostic procedures, therapeutic interventions (drainage, injection therapies, neurolysis, and radiofrequency ablation) can also be used in children and can provide an alternative to surgery in selected cases. With justified indications and precise performance, CT-guided interventions can be successful in pediatric patients with limited risks. (orig.)

Eliminating mental disability as a legal criterion in deprivation of liberty cases: The impact of the Convention on the Rights of Persons With Disabilities on the insanity defense, civil commitment, and competency law.

Science.gov (United States)

Slobogin, Christopher

2015-01-01

A number of laws that are associated with deprivations of liberty, including the insanity defense, civil commitment, guardianship of the person and numerous competency doctrines in the criminal context, require proof of mental disability as a predicate. The Convention on the Rights of Persons With Disabilities commands signatory states to eliminate that predicate. Summarizing principles set out in my book Minding Justice: Laws That Deprive People With Mental Disability of Life and Liberty, I explain how this seemingly radical stance can be implemented. Specifically, this article proposes adoption of an "integrationist defense" in the criminal context, an "undeterrability requirement" when the state seeks preventive detention outside of the criminal process, and a "basic rationality and self-regard test" for incompetency determinations. None of these proposals requires proof of a mental disorder as a predicate condition. Copyright © 2015 Elsevier Ltd. All rights reserved.

NOx emission was extremely decreased by PREDIC (PREmixed lean DIesel Combustion) in which fuel was injected at very early stage of compression stroke and the combustion started at near the TDC by self ignition. We have considered that NOx reduction is caused the decrease of a region of stoichiometric mixture ratio by means of extremely early injection. Therefore the homogeneity is very important to decrease of NOx. In this study to investigate the effect of mixture homogeneity in the PREDIC, gaseous fuels (DME, CH4) were charged into the intake, by the combination of direct fuel injection, the mixture heterogeneity was positively changed. In addition the mixture formation process is shown in aid of numerical simulation, it is observed that the homogeneous has the advantage of low NOx emission in PREDIC region. 9 refs., 10 figs., 1 tab.

Tobacco use is estimated to kill 7 million people a year. Nicotine is highly addictive, but surveys indicate that almost 70% of US and UK smokers would like to stop smoking. Although many smokers attempt to give up on their own, advice from a health professional increases the chances of quitting. As of 2016 there were 3.5 billion Internet users worldwide, making the Internet a potential platform to help people quit smoking. To determine the effectiveness of Internet-based interventions for smoking cessation, whether intervention effectiveness is altered by tailoring or interactive features, and if there is a difference in effectiveness between adolescents, young adults, and adults. We searched the Cochrane Tobacco Addiction Group Specialised Register, which included searches of MEDLINE, Embase and PsycINFO (through OVID). There were no restrictions placed on language, publication status or publication date. The most recent search was conducted in August 2016. We included randomised controlled trials (RCTs). Participants were people who smoked, with no exclusions based on age, gender, ethnicity, language or health status. Any type of Internet intervention was eligible. The comparison condition could be a no-intervention control, a different Internet intervention, or a non-Internet intervention. To be included, studies must have measured smoking cessation at four weeks or longer. Two review authors independently assessed and extracted data. We extracted and, where appropriate, pooled smoking cessation outcomes of six-month follow-up or more, reporting short-term outcomes narratively where longer-term outcomes were not available. We reported study effects as a risk ratio (RR) with a 95% confidence interval (CI).We grouped studies according to whether they (1) compared an Internet intervention with a non-active control arm (e.g. printed self-help guides), (2) compared an Internet intervention with an active control arm (e.g. face-to-face counselling), (3) evaluated the

Refusal to medical interventions is the not acceptance, voluntary and free, of an indicated medical intervention. What the physician should do in case of refusal? It is understandable that the rejection of a validated medical intervention is difficult to accept by the responsible physician when raises the conflict protection of life versus freedom of choice. Therefore it is important to follow some steps to incorporate the most relevant aspects of the conflict. These steps include: 1) Give complete information to patients, informing on possible alternatives, 2) determine whether the patient can decide (age, competency and level of capacity), 3) to ascertain whether the decision is free, 4) analyze the decision with the patient, 5) to persuade, 6) if the patient kept in the rejection decision, consider conscientious objection, 7) take the decision based on the named criteria, 8) finally, if the rejection is accepted, offer available alternatives.

To evaluate the current status of interventional radiology in Canada. A questionnaire was sent to 28 Canadian interventional radiologists (defined as a physician who performs any type of interventional procedure, including biopsies, but excluding interventional neuroradiology) practising in both tertiary and community hospitals in the major centres in all provinces except Prince Edward Island. Twenty-two (79%) of 28 surveys were completed and returned, providing data about 86 interventional radiologists (IRs). IRs were performing almost all of the following procedures at their institutions: inferior vena cava filter placement, venous angioplasty, dialysis fistula angioplasty, diagnostic and therapeutic pulmonary and bronchial artery procedures, diagnostic and therapeutic procedures of the lower extremity and renal arteries, percutaneous abscess and biliary drainage procedures, percutaneous nephrostomy, and fibroid embolization. A second group of procedures, performed by both IRs and non-radiologists in most institutions, included: all types of central venous catheter placements, pleural drainage, and gastrostomy tube placement. Procedures not being performed by anyone in a number of institutions included: dialysis graft thrombolysis, varicocele embolization, transjugular intrahepatic portosystemic shunts, palliative stenting of the gastrointestinal tract, fallopian tube recannalization, and liver and prostate tumour treatments. The factors most often limiting the respondents' ability to provide a comprehensive interventional service were the interventional radiology inventory budget and the availability of interventional radiology rooms; 50% of respondents indicated the number of available nurses, technologists and IRs was also an important limiting factor. IRs in Canada still play a major role in many of the most commonly performed procedures. However, limited availability of resources and personnel in many institutions may be hampering the ability of IRs to

1984-01-01

The papers published during this past year in the area of interventional vascular radiology presented some useful modifications and further experiences both in the area of thromboembolic therapy and in dilation and thrombolysis, but no new techniques. As an introductory subject, an excellent monograph reviewing the current spectrum of pharmacoangiography was presented in Radiographics. Although the presented material is primarily in diagnostic application of various pharmacologic agents used today to facilitate demonstration of certain diagnostic criteria of various disease processes, both vasodilatory and vasoconstrictive reaction to these agents are widely used in various therapeutic vascular procedures. This monograph should be reviewed by every angiographer whether or not he or she performs interventional procedures, and it would be very convenient to have this table available in the angiography suite. In a related subject, Bookstein and co-workers have written an excellent review concerning pharmacologic manipulations of various blood coagulative parameters during angiography. Understanding the proper method of manipulation of the bloodclotting factors during angiography, and especially during interventional angiography, is extremely important. Particularly, the method of manipulating the coagulation with the use of heparin and protamine and modification of the platelet activity by using aspirin and dipyridamole are succinctly reviewed. The systemic and selective thrombolytic activities of streptokianse are also discussed

There is a lack of knowledge about specific components that make interventions effective in preventing or reducing child maltreatment. The aim of the present meta-analysis was to increase this knowledge by summarizing findings on effects of interventions for child maltreatment and by examining potential moderators of this effect, such as intervention components and study characteristics. Identifying effective components is essential for developing or improving child maltreatment interventions. A literature search yielded 121 independent studies (N = 39,044) examining the effects of interventions for preventing or reducing child maltreatment. From these studies, 352 effect sizes were extracted. The overall effect size was significant and small in magnitude for both preventive interventions (d = 0.26, p child maltreatment. For preventive interventions, larger effect sizes were found for short-term interventions (0-6 months), interventions focusing on increasing self-confidence of parents, and interventions delivered by professionals only. Further, effect sizes of preventive interventions increased as follow-up duration increased, which may indicate a sleeper effect of preventive interventions. For curative interventions, larger effect sizes were found for interventions focusing on improving parenting skills and interventions providing social and/or emotional support. Interventions can be effective in preventing or reducing child maltreatment. Theoretical and practical implications are discussed.

Diagnostic interventions in nuclear medicine

International Nuclear Information System (INIS)

Thrall, J.H.; Swanson, D.P.

1989-01-01

Diagnostic interventions in nuclear medicine may be defined as the coadministration of a nonradioactive drug or application of a physical stimulus or physiologic maneuver to enhance the diagnostic utility of a nuclear medicine test. The rationale for each interventional maneuver follows from the physiology or metabolism of the particular organ or organ system under evaluation. Diagnostic inference is drawn from the pattern of change in the biodistribution of the tracer in response to the intervention-induced change in metabolism or function. In current practice, the most commonly performed interventional maneuvers are aimed at studies of the heart, genitourinary system, hepatobiliary system, and gastrointestinal tract. The single most commonly performed interventional study in the United States is the stress Thallium-201 myocardial perfusion scan aimed at the diagnosis of coronary artery disease. The stress portion of the study is accomplished with dynamic leg exercise on a treadmill and is aimed at increasing myocardial oxygen demands. Areas of myocardium distal to hemodynamically significant lesions in the coronary arteries become ischemic at peak stress due to the inability of the stenotic vessel to respond to the oxygen demand/blood flow needs of the myocardium. Ischemic areas are readily recognized as photopenic defects on scans obtained immediately after exercise, with normalization upon delayed imaging. Diuresis renography is aimed at the differential diagnosis of hydroureteronephrosis. By challenging the urinary tract collecting structures with an augmented urine flow, dilated, unobstructed systems can be differentiated from systems with significant mechanical obstruction. 137 references

The decrease in angiographic procedures as a result of less invasive imaging modalities has been counterbalanced by the rise in interventional radiological techniques. Because the interventional radiologist behaves somewhat like a surgeon, his legal responsibilities also approach those of his surgical colleagues. The basic concerns of negligent malpractice are amplified by the issues of informed consent and vicarious liability. Also, damages resulting from these procedures are costly because of the severity of the injuries. The angiographer must become versed in medicolegal issues of this rapidly evolving specialty

Unintended pregnancy among adolescents represents an important public health challenge in high-income countries, as well as middle- and low-income countries. Numerous prevention strategies such as health education, skills-building and improving accessibility to contraceptives have been employed by countries across the world, in an effort to address this problem. However, there is uncertainty regarding the effects of these interventions, hence the need to review the evidence-base. To assess the effects of primary prevention interventions (school-based, community/home-based, clinic-based, and faith-based) on unintended pregnancies among adolescents. We searched all relevant studies regardless of language or publication status up to November 2015. We searched the Cochrane Fertility Regulation Group Specialised trial register, The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2015 Issue 11), MEDLINE, EMBASE, LILACS, Social Science Citation Index and Science Citation Index, Dissertations Abstracts Online, The Gray Literature Network, HealthStar, PsycINFO, CINAHL and POPLINE and the reference lists of articles. We included both individual and cluster randomised controlled trials (RCTs) evaluating any interventions that aimed to increase knowledge and attitudes relating to risk of unintended pregnancies, promote delay in the initiation of sexual intercourse and encourage consistent use of birth control methods to reduce unintended pregnancies in adolescents aged 10 years to 19 years. Two authors independently assessed trial eligibility and risk of bias, and extracted data. Where appropriate, binary outcomes were pooled using a random-effects model with a 95% confidence interval (Cl). Where appropriate, we combined data in meta-analyses and assessed the quality of the evidence using the GRADE approach. We included 53 RCTs that enrolled 105,368 adolescents. Participants were ethnically diverse. Eighteen studies randomised individuals, 32

RESULTADOS: Chile es el país con mejores indicadores de coberturas crudas y efectivas, seguido por México y Colombia, y existen brechas importantes entre regiones, departamentos o estados. CONCLUSIONES: La métrica de cobertura efectiva es un indicador sensible que relaciona la necesidad de las intervenciones en salud, su utilización y calidad, lo que permite valorar los programas de salud al aportar datos precisos de dónde y a quién deben dirigirse los recursos y esfuerzos nacionales para que los países alcancen los propósitos y metas planteados.OBJECTIVE: To measure effective coverage for ll health interventions in Latin America including the children's, women's and adult health, as part of program evaluation. MATERIAL AND METHODS: Interventions were selected; the definitions and calculation methods were harmonized according to the information available to ensure comparability between countries. RESULTS: Chile has better indicators of crude and effective coverage followed by Mexico and Colombia.There are significant gaps between regions, counties or states. CONCLUSIONS: The health metric on effective coverage is a sensitive indicator that links three important aspects: Coverage of health interventions, use of health services, and access to such services. Effective coverage is a good tool to evaluate health programs performance, and also provides data of where and to whom the system should address national efforts and resources to achieve the purposes and goals set.

2007-10-01

The purpose of this study was to identify the effects of a physical activity-behavior modification combined intervention(PABM-intervention) on metabolic risk factors in overweight and obese elementary school children. Thirty-two participants (BMI>or=85 percentile or relative obesity>or=10) were allocated to the PABM-intervention group and behavior modification only intervention group. The PABM-intervention was composed of exercise intervention consisting of 50 minutes of physical activity(Hip-hop dance & gym-based exercises) twice a week and the behavior modification intervention consisted of 50 minutes of instruction for modifying lifestyle habits(diet & exercise) once a week. Effectiveness of intervention was based on waist circumference, BP, HDL-cholesterol, TG, and fasting glucose before and after the intervention. The proportion of subjects with 1, 2, 3 or more metabolic risk factors were 28.1, 43.8, and 15.6%, respectively. After the 8-week intervention, waist circumference, systolic BP, diastolic BP, and HDL-cholesterol changed significantly(p<.01) in the PABM group. This provides evidence that a PABM-intervention is effective in changing metabolic risk factors such as waist circumference, systolic BP, diastolic BP, and HDL-cholesterol in overweight and obese elementary school children.

Normal Peace: A New Strategic Narrative of Intervention

Directory of Open Access Journals (Sweden)

Nicolas Lemay-Hebert

2017-09-01

Full Text Available International actors have used multiple discursive frameworks for justifying interventions, from human security to the responsibility to protect, and, most recently, resilience-building. We argue that the language of normalization, hidden behind these narratives of interventions, has also contributed to structure the intervention landscape, albeit in less obvious and overt ways than other competing narratives of intervention. This article disentangles the different practices of normalization in order to highlight their ramifications. It introduces the concept of normal peace—a new conceptual reference to understand interventions undertaken by the international community to impose, restore or accept normalcy in turbulent societies. The article argues that the optimization of interventions entails selective responses to govern risk and adapt to the transitional international order. The art of what is politically possible underlines the choice of optimal intervention, be that to impose an external order of normalcy, restore the previous order of normalcy, or accept the existing order of normalcy.

Are All Interventions Created Equal? A Multi-Threat Approach to Tailoring Stereotype Threat Interventions

OpenAIRE

Shapiro, Jenessa R.; Williams, Amy M.; Hambarchyan, Mariam

2012-01-01

To date, stereotype threat interventions have been considered interchangeable. Across 4 experiments, the present research demonstrates that stereotype threat interventions need to be tailored to the specific form of experienced stereotype threat to be effective. The Multi-Threat Framework (Shapiro & Neuberg, 2007) distinguishes between group-as-target stereotype threats—concerns that a stereotype-relevant performance will reflect poorly on the abilities of one’s group—and self-as-target stere...

Staff lens doses in interventional urology. A comparison with interventional radiology, cardiology and vascular surgery values

International Nuclear Information System (INIS)

Vano, E; Fernandez, J M; Sanchez, R M; Resel, L E; Moreno, J

2016-01-01

The purpose of this work is to evaluate radiation doses to the lens of urologists during interventional procedures and to compare them with values measured during interventional radiology, cardiology and vascular surgery. The measurements were carried out in a surgical theatre using a mobile C-arm system and electronic occupational dosimeters (worn over the lead apron). Patient and staff dose measurements were collected in a sample of 34 urology interventions (nephrolithotomies). The same dosimetry system was used in other medical specialties for comparison purposes. Median and 3rd quartile values for urology procedures were: patient doses 30 and 40 Gy cm 2 ; personal dose equivalent Hp(10) over the apron (μSv/procedure): 393 and 848 (for urologists); 21 and 39 (for nurses). Median values of over apron dose per procedure for urologists resulted 18.7 times higher than those measured for radiologists and cardiologists working with proper protection (using ceiling suspended screens) in catheterisation laboratories, and 4.2 times higher than the values measured for vascular surgeons at the same hospital. Comparison with passive dosimeters worn near the eyes suggests that dosimeters worn over the apron could be a reasonable conservative estimate for ocular doses for interventional urology. Authors recommend that at least the main surgeon uses protective eyewear during interventional urology procedures. (paper)

Health behaviour change interventions for couples: A systematic review.

Science.gov (United States)

Arden-Close, Emily; McGrath, Nuala

2017-05-01

Partners are a significant influence on individuals' health, and concordance in health behaviours increases over time in couples. Several theories suggest that couple-focused interventions for health behaviour change may therefore be more effective than individual interventions. A systematic review of health behaviour change interventions for couples was conducted. Systematic search methods identified randomized controlled trials (RCTs) and non-randomized interventions of health behaviour change for couples with at least one member at risk of a chronic physical illness, published from 1990-2014. We identified 14 studies, targeting the following health behaviours: cancer prevention (6), obesity (1), diet (2), smoking in pregnancy (2), physical activity (1) and multiple health behaviours (2). In four out of seven trials couple-focused interventions were more effective than usual care. Of four RCTs comparing a couple-focused intervention to an individual intervention, two found that the couple-focused intervention was more effective. The studies were heterogeneous, and included participants at risk of a variety of illnesses. In many cases the intervention was compared to usual care for an individual or an individual-focused intervention, which meant the impact of the couplebased content could not be isolated. Three arm studies could determine whether any added benefits of couple-focused interventions are due to adding the partner or specific content of couple-focused interventions. Statement of contribution What is already known on this subject? Health behaviours and health behaviour change are more often concordant across couples than between individuals in the general population. Couple-focused interventions for chronic conditions are more effective than individual interventions or usual care (Martire, Schulz, Helgeson, Small, & Saghafi, ). What does this study add? Identified studies targeted a variety of health behaviours, with few studies in any one area. Further

Horvath, Keith J; Bauermeister, José A

2017-02-01

We assessed whether young men who have sex with men's acceptability with the online Get Connected! intervention and subsequent sexual health decision making were influenced by their baseline eHealth literacy (high vs. low competency) and intervention tailoring (tailored or nontailored intervention condition). Compared to the high eHealth literacy/tailored intervention group: (1) those in the low eHealth literacy/tailored intervention condition and participants in the nontailored intervention condition (regardless of eHealth literacy score) reported lower intervention information quality scores; and (2) those in the low eHealth literacy/nontailored intervention group reported lower intervention system quality scores and that the intervention had less influence on their sexual health decision making. Future similar intervention research should consider how eHealth literacy might influence participants' abilities to navigate intervention content and integrate it into their sexual decision making.

Nursing burnout interventions: what is being done?

Science.gov (United States)

Henry, Barbara J

2014-04-01

Many studies have documented high prevalence of burnout and compassion fatigue in oncology nurses. Burnout has detrimental effects on nurses, patients, and healthcare organizations. However, burnout interventions have been shown to improve the physical and mental health of nurses, patient satisfaction, and the organizational bottom line by reducing associated costs of burnout. Although treatment centers may prevent and correct burnout in oncology nurses by providing various interventions, few articles focus on those interventions. This article compiles and describes interventions that will serve as a reference to nurses and healthcare organization leaders interested in implementing similar programs.

Smoking cessation interventions delivered via text messaging on mobile phones may enhance motivations to quit smoking. The goal of this narrative review is to describe the text messaging interventions' theoretical contents, frequency and duration, treatment outcome, and sample characteristics such as age and motivation to quit, to better inform the future development of this mode of intervention. Studies were included if text messaging was primarily used to deliver smoking cessation intervention and published in English in a peer-reviewed journal. All articles were coded by two independent raters to determine eligibility and to extract data. Twenty-two studies described 15 text messaging interventions. About half of the interventions recruited adults (ages 30-40) and the other half targeted young adults (ages 18-29). Fourteen interventions sent text messages during the quit phase, 10 had a preparation phase and eight had a maintenance phase. The number of text messages and the duration of the intervention varied. All used motivational messages grounded in social cognitive behavioral theories, 11 used behavioral change techniques, and 14 used individually tailored messages. Eleven interventions also offered other smoking cessation tools. Three interventions yielded smoking cessation outcomes greater than the control condition. The proliferation of text messaging in recent years suggests that text messaging interventions may have the potential to improve smoking cessation rates. Detailed summary of the interventions suggests areas for future research and clinical application. More rigorous studies are needed to identify components of the interventions that can enhance their acceptability, feasibility and efficacy. Copyright © 2013. Published by Elsevier Ltd.

Decisions to smoke are made within a broad social context. Community interventions use co-ordinated, widespread, multi-component programmes to try and influence behaviour. To determine the effectiveness of community interventions in preventing the uptake of smoking in young people. The Tobacco Addiction group specialised register, Medline and other health, psychology and public policy electronic databases were searched, the bibliographies of identified studies were checked and contact was made with content area specialists. Searches were updated in September 2002. Randomised and non randomised controlled trials that assessed the effectiveness of multi-component community interventions compared to no intervention or to single component or school-based programmes only. Reported outcomes had to include smoking behaviour in young people under the age of 25 years. Information relating to the characteristics and the content of community interventions, participants, outcomes and methods of the study was extracted by one reviewer and checked by a second. Studies were combined using qualitative narrative synthesis. Seventeen studies were included in the review, 46 studies did not meet all of the inclusion criteria. All studies used a controlled trial design, with six using random allocation of schools or communities. Of thirteen studies which compared community interventions to no intervention controls, two, which were part of cardiovascular disease prevention programmes, reported lower smoking prevalence. Of three studies comparing community interventions to school-based programmes only, one found differences in reported smoking prevalence. One study reported a lower rate of increase in prevalence in a community receiving a multi-component intervention compared to a community exposed to a mass media campaign alone. One study reported a significant difference in smoking prevalence between a group receiving a media, school and homework intervention compared to a group

Speech and language intervention in bilinguals

Eliane Ramos

2011-12-01

Full Text Available Increasingly, speech and language pathologists (SLPs around the world are faced with the unique set of issues presented by their bilingual clients. Some professional associations in different countries have presented recommendations when assessing and treating bilingual populations. In children, most of the studies have focused on intervention for language and phonology/ articulation impairments and very few focus on stuttering. In general, studies of language intervention tend to agree that intervention in the first language (L1 either increase performance on L2 or does not hinder it. In bilingual adults, monolingual versus bilingual intervention is especially relevant in cases of aphasia; dysarthria in bilinguals has been barely approached. Most studies of cross-linguistic effects in bilingual aphasics have focused on lexical retrieval training. It has been noted that even though a majority of studies have disclosed a cross-linguistic generalization from one language to the other, some methodological weaknesses are evident. It is concluded that even though speech and language intervention in bilinguals represents a most important clinical area in speech language pathology, much more research using larger samples and controlling for potentially confounding variables is evidently required.

Muñoz San José, A; Oreja-Guevara, C; Cebolla Lorenzo, S; Carrillo Notario, L; Rodríguez Vega, B; Bayón Pérez, C

2016-03-01

Depression or anxiety in multiple sclerosis (MS) has been linked to a more severe course of the disease and higher numbers of relapses, in addition to poorer treatment adherence and exacerbated immune system dysregulation. Recent investigations indicate that psychotherapeutic interventions for stress management, such as mindfulness-based interventions (MBIs), could improve quality of life, depression, anxiety, and fatigue in MS patients. Mindfulness fosters the ability to slow down and observe experiences as they truly are, which improves affect regulation. Mindfulness is acquired through training; its advantage over other psychotherapeutic interventions is that effects may remain over time, since cultivating mindfulness depends on regular practising of abilities learned during training. The objective of this article is to review the current evidence of psychotherapeutic and psychosocial interventions, including MBIs for stress management, and their beneficial effects on MS patients.

AimThe aim of this study was to assess the rates of haemorrhagic and thrombotic complications in patients undergoing interventional tumour ablation with and without peri-interventional low-molecular-weight heparin (LMWH) thrombosis prophylaxis.MethodsPatients presented with primary and secondary neoplastic lesions in the liver, lung, kidney, lymph nodes and other locations. A total of 781 tumour ablations (radiofrequency ablation, n = 112; interstitial brachytherapy, n = 669) were performed in 446 patients over 22 months; 260 were conducted under peri-interventional thrombosis prophylaxis with LMWH (H-group;) and 521 without this (NH-group, in 143 of these, LMWH was given post-interventionally).ResultsSixty-three bleeding events occurred. There were significantly more bleedings in the H-group than in the NH-group (all interventions, 11.66 and 6.26 %, p = 0.0127; liver ablations, 12.73 and 7.1 %, p = 0.0416). The rate of bleeding events Grade ≥ III in all procedures was greater by a factor of >2.6 in the H-group than in the NH-group (4.64 and 1.73 %, p = 0.0243). In liver tumour ablations, the corresponding factor was about 3.3 (5.23 and 1.54 %, p = 0.028). In uni- and multivariate analyses including covariates, the only factor constantly and significantly associated with the rate of haemorrhage events was peri-interventional LMWH prophylaxis. Only one symptomatic lung embolism occurred in the entire cohort (NH-group). The 30- and 90-day mortalities were significantly greater in the H-group than in the NH-group.ConclusionsPeri-interventional LMWH thrombosis prophylaxis should be considered with caution. The rate of clinically relevant thrombotic events was extremely low.

Gómez Puente, Juana María; Martínez-Marcos, Mercedes

To identify the most effective interventions in overweight and obese adults. A narrative review through a search of the literature in databases PubMed, Cochrane, Joanna Briggs Institute, EMBASE, Cuiden y Cinahl with free and controlled language (MeSH terms) using Boolean operators AND and NOT. The research was limited to articles published between 2007 and 2015. Eighteen articles were selected based on the established inclusion and exclusion criteria. Different types of interventions were identified based on the modification of lifestyles, mainly diet, physical activity and behavior. Major differences were found in specific content, degree of intensity of interventions, time tracking and elements evaluated. Most of studies found statistically significant weight loss but this was limited in terms of weight and number of people. Web-based interventions have no uniform effect on weight loss but achieve similar levels to face-to-face interventions in maintaining weight loss. The combination of personalised diet, exercise and cognitive behavioural therapy is the most effective form of intervention in overweight and obesity. There is insufficient data to indicate whether group or individual interventions are more effective. Online intervention allows greater accessibility and lower cost.

Identifying Demand Responses to Illegal Drug Supply Interdictions.

Science.gov (United States)

Cunningham, Scott; Finlay, Keith

2016-10-01

Successful supply-side interdictions into illegal drug markets are predicated on the responsiveness of drug prices to enforcement and the price elasticity of demand for addictive drugs. We present causal estimates that targeted interventions aimed at methamphetamine input markets ('precursor control') can temporarily increase retail street prices, but methamphetamine consumption is weakly responsive to higher drug prices. After the supply interventions, purity-adjusted prices increased then quickly returned to pre-treatment levels within 6-12 months, demonstrating the short-term effects of precursor control. The price elasticity of methamphetamine demand is -0.13 to -0.21 for self-admitted drug treatment admissions and between -0.24 and -0.28 for hospital inpatient admissions. We find some evidence of a positive cross-price effect for cocaine, but we do not find robust evidence that increases in methamphetamine prices increased heroin, alcohol, or marijuana drug use. This study can inform policy discussions regarding other synthesized drugs, including illicit use of pharmaceuticals. Copyright © 2015 John Wiley & Sons, Ltd.

Krass, Ines

2016-06-01

Background In the field of pharmacist intervention research it is often difficult to conform to the rigorous requirements of the "true experimental" models, especially the requirement of randomization. When randomization is not feasible, a practice based researcher can choose from a range of "quasi-experimental designs" i.e., non-randomised and at time non controlled. Objective The aim of this article was to provide an overview of quasi-experimental designs, discuss their strengths and weaknesses and to investigate their application in pharmacist intervention research over the previous decade. Results In the literature quasi experimental studies may be classified into five broad categories: quasi-experimental design without control groups; quasi-experimental design that use control groups with no pre-test; quasi-experimental design that use control groups and pre-tests; interrupted time series and stepped wedge designs. Quasi-experimental study design has consistently featured in the evolution of pharmacist intervention research. The most commonly applied of all quasi experimental designs in the practice based research literature are the one group pre-post-test design and the non-equivalent control group design i.e., (untreated control group with dependent pre-tests and post-tests) and have been used to test the impact of pharmacist interventions in general medications management as well as in specific disease states. Conclusion Quasi experimental studies have a role to play as proof of concept, in the pilot phases of interventions when testing different intervention components, especially in complex interventions. They serve to develop an understanding of possible intervention effects: while in isolation they yield weak evidence of clinical efficacy, taken collectively, they help build a body of evidence in support of the value of pharmacist interventions across different practice settings and countries. However, when a traditional RCT is not feasible for

Psychosocial interventions for premature ejaculation

Directory of Open Access Journals (Sweden)

Tamara Melnik

Full Text Available BACKGROUND: Premature ejaculation (PE is a very common sexual dysfunction among patients, and with varying prevalence estimates ranging from 3% to 20%. Although psychological issues are present in most patients with premature PE, as a cause or as a consequence, research on the effects of psychological approaches for PE has in general not been controlled or randomised and is lacking in long-term follow up. OBJECTIVE: To assess the efficacy of psychosocial interventions for PE. CRITERIA FOR CONSIDERING STUDIES FOR THIS REVIEW: Trials were searched in computerized general and specialized databases, such as: MEDLINE by PubMed (1966 to 2010; PsycINFO (1974 to 2010; EMBASE (1980 to 2010; LILACS (1982 to 2010; the Cochrane Central Register of Controlled Trials (Cochrane Library, 2010; and by checking bibliographies, and contacting manufacturers and researchers. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials evaluating psychosocial interventions compared with different psychosocial interventions, pharmacological interventions, waiting list, or no treatment for PE. DATA COLLECTION AND ANALYSIS: Information on patients, interventions, and outcomes was extracted by at least two independent reviewers using a standard form. The primary outcome measure for comparing the effects of psychosocial interventions to waiting list and standard medications was improvement in IELT (i.e., time from vaginal penetration to ejaculation. The secondary outcome was change in validated PE questionnaires. MAIN RESULTS: In one study behavioral therapy (BT was significantly better than waiting list for duration of intercourse (MD (mean difference 407.90 seconds, 95% CI 302.42 to 513.38, and couples' sexual satisfaction (MD -26.10, CI -50.48 to -1.72. BT was also significantly better for a new functional-sexological treatment (FS (MD 412.00 seconds, 95% CI 305.88 to 518.12, change over time in subjective perception of duration of intercourse (Women: MD 2

Interactivity generates paradox in that the interactive control by one system C of predicates about another system-under-study S may falsify these predicates. An ''interactive logic'' is formulated to resolve this paradox of interactivity. The construction generalizes one, the Galois connection, used by Von Neumann for the similar quantum paradox. The construction is applied to a transition system, a concept that includes general systems, automata, and quantum systems. In some (classical) automata S, the interactive predicates about S show quantumlike complementarity arising from interactivity. The interactive paradox generates the quantum paradox. Some classical S's have noncommutative algebras of interactively observable coordinates similar to the Heisenberg algebra of a quantum system. Such S's are ''hidden variable'' models of quantum theory not covered by the hidden variable studies of Von Neumann, Bohm, Bell, or Kochen and Specker. It is conceivable that some quantum effects in Nature arise from interactivity. (author)

Towards a Categorical Account of Conditional Probability

Directory of Open Access Journals (Sweden)

Robert Furber

2015-11-01

Full Text Available This paper presents a categorical account of conditional probability, covering both the classical and the quantum case. Classical conditional probabilities are expressed as a certain "triangle-fill-in" condition, connecting marginal and joint probabilities, in the Kleisli category of the distribution monad. The conditional probabilities are induced by a map together with a predicate (the condition. The latter is a predicate in the logic of effect modules on this Kleisli category. This same approach can be transferred to the category of C*-algebras (with positive unital maps, whose predicate logic is also expressed in terms of effect modules. Conditional probabilities can again be expressed via a triangle-fill-in property. In the literature, there are several proposals for what quantum conditional probability should be, and also there are extra difficulties not present in the classical case. At this stage, we only describe quantum systems with classical parametrization.

NO{sub x} emission was remarkably reduced by PREDIC (PREmixed lean DIesel Combustion) system in which fuel was injected at very early stage of compression stroke and the major part of the fuel is considered to be burned with self-ignition of premixed charge around TDC. However PREDIC system had some problems, a restriction of a high load operation was one of these problems. In order to investigate the combustion characteristics of PREDIC at the richer operation limit, a test engine was operated with gaseous fuel-air mixture where less heterogeneous mixture can be formed than that of conventional diesel engines. A steep pressure rise or the abrupt increase in NO{sub x} emission determined the richer operation limit. This was at 2 to 2.4 of excess air ratio. Supercharging operation enabled the high load operation more than 2.4 of excess air ratio. (author)

2016-12-01

Full Text Available This piece of work proposes to descriptively investigate the structures of complex verbs in Meiteilon. The categorization of such verbs is based on the nature of semantic and syntactic functions of a lexeme or verbal lexeme. A lexeme or verbal lexeme in Meiteilon may have multifunctional properties in the nature of occurrence. Such lexical items can be co-occurred together in a phrase as single functional word. Specifically, in the co-occurrences of two lexical items, the first component of lexical items has different semantic and syntactic functions in comparison to semantic and syntactic functions of the second component of lexical items. Such co-occurrences of two lexical items are the forms of complex verb that are covered with the term complex predicate in this work. The investigation in constructing complex predicate is thoroughly presenting in this work. Keywords: Structures, complex verb, conjunct verb, compound verb, complex predicate

2004-01-01

The main objective of the 'Computerized Management of Plant Intervention Tasks' is to help the staff of a nuclear or a conventional power plant or of any other complex industrial facility (chemical industries, refineries, and so on) in planning, organizing, and carrying out any (preventive or corrective) maintenance task. This 'Computerized Management of Plant Intervention Tasks' is organized around a data base of all plant components in the facility that might be subjected to maintenance or tagout. It allows to manage, by means of intelligent and configurable 'mail service', the course of the intervention requests as well as various treatments of those requests, in a safe and efficient way, adapted to each particular organization. The concept of 'Computerized Management' of plant intervention tasks was developed by BELGATOM in 1983 for the Belgian nuclear power plants of ELECTRABEL. A first implementation of this concept was made at that time for the Doel NPP under the name POPIT (Programming Of Plant Intervention Tasks). In 1988, it was decided to proceed to a functional upgrade of the application, using advanced software and hardware techniques and products, and to realize a second implementation in the Tihange NPP under the name ACM (Application Consignation Maintenance).

2015-01-01

The anthropological study of human biology, health, and child development provides a model with potential to address the gap in population-wide mental health interventions. Four key concepts from human biology can inform public mental health interventions: life history theory and tradeoffs, redundancy and plurality of pathways, cascades and multiplier effects in biological systems, and proximate feedback systems. A public mental health intervention for former child soldiers in Nepal is used to illustrate the role of these concepts in intervention design and evaluation. Future directions and recommendations for applying human biology theory in pursuit of public mental health interventions are discussed. © 2014 Wiley Periodicals, Inc.

There has been a significant increase in the availability of online programs for alcohol problems. A systematic review of the research evidence underpinning these programs is timely. Our objective was to review the efficacy of online interventions for alcohol misuse. Systematic searches of Medline, PsycINFO, Web of Science, and Scopus were conducted for English abstracts (excluding dissertations) published from 1998 onward. Search terms were: (1) Internet, Web*; (2) online, computer*; (3) alcohol*; and (4) E\\effect*, trial*, random* (where * denotes a wildcard). Forward and backward searches from identified papers were also conducted. Articles were included if (1) the primary intervention was delivered and accessed via the Internet, (2) the intervention focused on moderating or stopping alcohol consumption, and (3) the study was a randomized controlled trial of an alcohol-related screen, assessment, or intervention. The literature search initially yielded 31 randomized controlled trials (RCTs), 17 of which met inclusion criteria. Of these 17 studies, 12 (70.6%) were conducted with university students, and 11 (64.7%) specifically focused on at-risk, heavy, or binge drinkers. Sample sizes ranged from 40 to 3216 (median 261), with 12 (70.6%) studies predominantly involving brief personalized feedback interventions. Using published data, effect sizes could be extracted from 8 of the 17 studies. In relation to alcohol units per week or month and based on 5 RCTs where a measure of alcohol units per week or month could be extracted, differential effect sizes to posttreatment ranged from 0.02 to 0.81 (mean 0.42, median 0.54). Pre-post effect sizes for brief personalized feedback interventions ranged from 0.02 to 0.81, and in 2 multi-session modularized interventions, a pre-post effect size of 0.56 was obtained in both. Pre-post differential effect sizes for peak blood alcohol concentrations (BAC) ranged from 0.22 to 0.88, with a mean effect size of 0.66. The available

2017-12-01

Effective community-based interventions are available to control hypertension. It is important to determine the economics of these interventions. Peer-reviewed studies from January 1995 through December 2015 were screened. Interventions were categorized into educational interventions, self-monitoring interventions, and screening interventions. Incremental cost-effectiveness ratios were summarized by types of interventions. The review was conducted in 2016. Thirty-four articles were included in the review (16 from the U.S., 18 from other countries), including 25 on educational interventions, three on self-monitoring interventions, and six on screening interventions. In the U.S., five (31.3%) studies on educational interventions were cost saving. Among the studies that found the interventions cost effective, the median incremental costs were $62 (range, $40-$114) for 1-mmHg reduction in systolic blood pressure (SBP) and $13,986 (range, $6,683-$58,610) for 1 life-year gained. Outside the U.S., educational interventions cost from $0.62 (China) to $29 (Pakistan) for 1-mmHg reduction in SBP. Self-monitoring interventions, evaluated in the U.S. only, cost $727 for 1-mmHg reduction in SBP and $41,927 for 1 life-year gained. For 1 quality-adjusted life-year, screening interventions cost from $21,734 to $56,750 in the U.S., $613 to $5,637 in Australia, and $7,000 to $18,000 in China. Intervention costs to reduce 1 mmHg blood pressure or 1 quality-adjusted life-year were higher in the U.S. than in other countries. Most studies found that the three types of interventions were either cost effective or cost saving. Quality of economic studies should be improved to confirm the findings.

On acquiring decision making skills for endovascular interventions.

Science.gov (United States)

Lanzer, Peter; Prechelt, Lutz

2008-11-01

To improve interventional training we propose a staged rational approach for decision making and skill acquisition. Education and training for endovascular interventions should start to develop the learners' decision-making skills by learning from explicit representations of master interventionist's tacit decision-making knowledge through implementation of the notions of generic interventional modules, interventional strategic and tactical designs. We hope that these suggestions will encourage action, stimulate dialogue and advance the precision of our learning, procedures, practice and patient care.

What interventions increase commuter cycling? A systematic review.

To identify interventions that will increase commuter cycling. All settings where commuter cycling might take place. Adults (aged 18+) in any country. Individual, group or environmental interventions including policies and infrastructure. A wide range of 'changes in commuter cycling' indicators, including frequency of cycling, change in workforce commuting mode, change in commuting population transport mode, use of infrastructure by defined populations and population modal shift. 12 studies from 6 countries (6 from the UK, 2 from Australia, 1 each from Sweden, Ireland, New Zealand and the USA) met the inclusion criteria. Of those, 2 studies were randomised control trials and the remainder preintervention and postintervention studies. The majority of studies (n=7) evaluated individual-based or group-based interventions and the rest environmental interventions. Individual-based or group-based interventions in 6/7 studies were found to increase commuter cycling of which the effect was significant in only 3/6 studies. Environmental interventions, however, had small but positive effects in much larger but more difficult to define populations. Almost all studies had substantial loss to follow-up. Despite commuter cycling prevalence varying widely between countries, robust evidence of what interventions will increase commuter cycling in low cycling prevalence nations is sparse. Wider environmental interventions that make cycling conducive appear to reach out to hard to define but larger populations. This could mean that environmental interventions, despite their small positive effects, have greater public health significance than individual-based or group-based measures because those interventions encourage a larger number of people to integrate physical activity into their everyday lives.

In patients with bronchial tumors, we frequently consider endoscopic treatment as the first treatment of choice. All computed tomography (CT) must satisfy several conditions necessary to analyze images by Synapse Vincent. To select safer and more precise approaches for patients with bronchial tumors, we determined the indications and efficacy of virtual navigation intervention for the treatment of bronchial tumors. We examined the efficacy of virtual navigation bronchial intervention for the treatment of bronchial tumors located at a variety of sites in the tracheobronchial tree using a high-speed 3-dimensional (3D) image analysis system, Synapse Vincent. Constructed images can be utilized to decide on the simulation and interventional strategy as well as for navigation during interventional manipulation in two cases. Synapse Vincent was used to determine the optimal planning of virtual navigation bronchial intervention. Moreover, this system can detect tumor location and alsodepict surrounding tissues, quickly, accurately, and safely. The feasibility and safety of Synapse Vincent in performing useful preoperative simulation and navigation of surgical procedures can lead to safer, more precise, and less invasion for the patient, and makes it easy to construct an image, depending on the purpose, in 5-10 minutes using Synapse Vincent. Moreover, if the lesion is in the parenchyma or sub-bronchial lumen, it helps to perform simulation with virtual skeletal subtraction to estimate potential lesion movement. By using virtual navigation system for simulation, bronchial intervention was performed with no complications safely and precisely. Preoperative simulation using virtual navigation bronchial intervention reduces the surgeon's stress levels, particularly when highly skilled techniques are needed to operate on lesions. This task, including both preoperative simulation and intraoperative navigation, leads to greater safety and precision. These technological instruments

Poor voice quality due to a voice disorder can lead to a reduced quality of life. In occupations where voice use is substantial it can lead to periods of absence from work. To evaluate the effectiveness of interventions to prevent voice disorders in adults. We searched MEDLINE (PubMed, 1950 to 2006), EMBASE (1974 to 2006), CENTRAL (The Cochrane Library, Issue 2 2006), CINAHL (1983 to 2006), PsychINFO (1967 to 2006), Science Citation Index (1986 to 2006) and the Occupational Health databases OSH-ROM (to 2006). The date of the last search was 05/04/06. Randomised controlled clinical trials (RCTs) of interventions evaluating the effectiveness of treatments to prevent voice disorders in adults. For work-directed interventions interrupted time series and prospective cohort studies were also eligible. Two authors independently extracted data and assessed trial quality. Meta-analysis was performed where appropriate. We identified two randomised controlled trials including a total of 53 participants in intervention groups and 43 controls. One study was conducted with teachers and the other with student teachers. Both trials were poor quality. Interventions were grouped into 1) direct voice training, 2) indirect voice training and 3) direct and indirect voice training combined.1) Direct voice training: One study did not find a significant decrease of the Voice Handicap Index for direct voice training compared to no intervention.2) Indirect voice training: One study did not find a significant decrease of the Voice Handicap Index for indirect voice training when compared to no intervention.3) Direct and indirect voice training combined: One study did not find a decrease of the Voice Handicap Index for direct and indirect voice training combined when compared to no intervention. The same study did however find an improvement in maximum phonation time (Mean Difference -3.18 sec; 95 % CI -4.43 to -1.93) for direct and indirect voice training combined when compared to no

Impairments in attention and memory are common sequelae following paediatric acquired brain injury (ABI). While it has been established that such impairments are long-term and, therefore, affect quality-of-life, there is a scarcity of evidence-based interventions to treat these difficulties. The current study aimed to pilot the efficacy of the Amsterdam Memory and Attention Training for Children (Amat-c: English version) using both neuropsychological and ecologically sensitive measures. It was expected that children with attention and memory difficulties post-ABI would show improved performance post-intervention on cognitive and ecological measures, with maintenance at 6 months post-intervention. Ten children with an ABI, between the ages of 8-13 years at the time of recruitment were identified through audits of presentations to a metropolitan paediatric hospital. Each child underwent screening, the 18 week intervention programme, pre-intervention, immediate and 6 month post-intervention assessments. Findings supported the hypothesis that children would show post-intervention (immediate and 6 month) improvement in areas of attention and memory, with generalization to everyday life. Preliminary results provide support for the efficacy of the Amat-c post-childhood ABI. A larger study is needed to confirm these findings, as a reduction in attention and memory difficulties will enhance everyday functioning.

Mobile technology is opening new avenues for healthcare providers to create and implement tailored and personalized health education programs. We estimate and compare the cost of developing an i-Pad based tailored interactive multimedia intervention (TIMI) and a print based (Photonovella) intervention to increase human papillomavirus (HPV) immunization. The development costs of the interventions were calculated using a societal perspective. Direct cost included the cost of planning the study, conducting focus groups, and developing the intervention materials by the research staff. Costs also included the amount paid to the vendors who produced the TIMI and Photonovella. Micro cost data on the staff time and materials were recorded in logs for tracking personnel time, meeting time, supplies and software purchases. The costs were adjusted for inflation and reported in 2015 USD. The total cost of developing the Photonovella was $66,468 and the cost of developing the TIMI was $135,978. The amortized annual cost for the interventions calculated at a 3% discount rate and over a 7-year period was $10,669 per year for the Photonovella and $21,825 per year for the TIMI intervention. The results would inform decision makers when planning and investing in the development of interactive multimedia health interventions. Copyright © 2017 Elsevier Ltd. All rights reserved.

We recognized that the complexity and surgical nature of many interventional radiology procedures dictate essential radiologic involvement into traditional anesthesiologic areas. They reviewed our experience with a variety of interventional procedures to document complications and problems related to anesthetic use (or misuse) and compile recommendations for rational monitoring and control for these procedures. In particular, the authors have studied complications of drug therapies and the treatment of these complications; use of complex anesthesia procedures (e.g., epidural anesthesia, succinylcholine blockage); reasons for choice of drugs (e.g., fentanyl vs meperidine vs morphine); and medico-legal aspects of radiologist performing traditional anesthesiology-type procedures

Development of a pediatric interventional radiology clinic is a necessary component of providing a pediatric interventional radiology service. Patient satisfaction is important when providing efficient, high-quality care. To analyze the care provided by a pediatric interventional radiology clinic from the perspective of efficiency and parent satisfaction, so as to identify areas for improvement. The prospective study was both quantitative and qualitative. The quantitative component measured clinic efficiency (waiting times, duration of clinic visit, nurse/physician time allocation and assessments performed; n = 91). The qualitative component assessed parental satisfaction with their experience with the pediatric interventional radiology clinic, using a questionnaire (5-point Likert scale) and optional free text section for feedback (n = 80). Questions explored the family's perception of relevance of information provided, consent process and overall satisfaction with their pediatric interventional radiology clinic experience. Families waited a mean of 11 and 10 min to meet the physician and nurse, respectively. Nurses and physicians spent a mean of 28 and 21 min with the families, respectively. The average duration of the pediatric interventional radiology clinic consultation was 56 min. Of 80 survey participants, 83% were satisfied with their experience and 94% said they believed providing consent before the day of the procedure was helpful. Only 5% of respondents were not satisfied with the time-efficiency of the interventional radiology clinic. Results show the majority of patients/parents are very satisfied with the pediatric interventional radiology clinic visit. The efficiency of the pediatric interventional radiology clinic is satisfactory; however, adherence to stricter scheduling can be improved. (orig.)

Visualizing value for money in public health interventions.

Leigh-Hunt, Nicholas; Cooper, Duncan; Furber, Andrew; Bevan, Gwyn; Gray, Muir

2018-01-23

The Socio-Technical Allocation of Resources (STAR) has been developed for value for money analysis of health services through stakeholder workshops. This article reports on its application for prioritization of interventions within public health programmes. The STAR tool was used by identifying costs and service activity for interventions within commissioned public health programmes, with benefits estimated from the literature on economic evaluations in terms of costs per Quality-Adjusted Life Years (QALYs); consensus on how these QALY values applied to local services was obtained with local commissioners. Local cost-effectiveness estimates could be made for some interventions. Methodological issues arose from gaps in the evidence base for other interventions, inability to closely match some performance monitoring data with interventions, and disparate time horizons of published QALY data. Practical adjustment for these issues included using population prevalences and utility states where intervention specific evidence was lacking, and subdivision of large contracts into specific intervention costs using staffing ratios. The STAR approach proved useful in informing commissioning decisions and understanding the relative value of local public health interventions. Further work is needed to improve robustness of the process and develop a visualization tool for use by public health departments. © The Author(s) 2018.

Modified crisis intervention for personality disorder.

Science.gov (United States)

Rudnick, A

1998-01-01

This study proposes that the goal of crisis intervention for persons with personality disorders should be to return them to their pre-crisis level of functioning, even though this is maladaptive. This is contrasted with standard crisis intervention, which aims to return normal or neurotic persons to their pre-crisis normal or neurotic functioning, usually by means of few and short-term therapeutic encounters. The modification proposed costs more time and resources in persons with personality disorders in crisis and fits the intervention to the personality type. This is illustrated by the case of Eve, a patient in crisis, whose pre-crisis functioning was maladaptive because of a dependent personality disorder. The goal of (modified) crisis intervention in this case was to return the patient to her dependent lifestyle, by means of pharmacotherapy combined with intensive supportive psychotherapy during 3-4 months of partial (day) hospitalization. The special nature of crisis in personality disorders is discussed.

The rapid proliferation of community-based health education programs has out-paced the knowledge base of behavior change strategies that are appropriate and effective for public health interventions. However, experiences from a variety of large-scale studies suggest that principles and techniques of social marketing may help bridge this gap. This article discusses eight essential aspects of the social marketing process: the use of a consumer orientation to develop and market intervention techniques, exchange theory as a model from which to conceptualize service delivery and program participation, audience analysis and segmentation strategies, the use of formative research in program design and pretesting of intervention materials, channel analysis for devising distribution systems and promotional campaigns, employment of the "marketing mix" concept in intervention planning and implementation, development of a process tracking system, and a management process of problem analysis, planning, implementation, feedback and control functions. Attention to such variables could result in more cost-effective programs that reach larger numbers of the target audience.

Interventional radiology has lot of advantages in dealing with various emergencies. The technique is minimally-invasive, highly-effective and immediately-efficient, moreover, it integrates the diagnosis with the therapy perfectly. Besides, the interventional techniques applied in emergency medicine include not only the vascular interventions,such as embolization, embolectomy, etc, but also the nonvascular interventions, such as tracheal s tent implantation, percutaneous vertebroplasty and so forth. However, importance has not been attached to the clinical use of interventional therapy in emergency medicine so far. It is imperative for us to promote the acceptance of interventional therapy in emergency medicine as well as to popularize the technique in clinical practice. (authors)

Full Text Available ABSTRACT Objective: to test the effects of behavioral and educational intervention by telephone on adherence of women with inappropriate periodicity to colpocytological examination. Method: quasi-experimental study with a sample of 524 women, selected with the following inclusion criteria: be aged between 25 and 64 years, have initiated sexual activity, have inappropriate periodicity of examination and have mobile or landline phone. The women were divided into two groups for application of behavioral and educational intervention by telephone. It was used an intervention script according to the principles of Motivational Interviewing. Results: on comparing the results before and after the behavioral and educational interventions, it was found that there was a statistically significant change (p = 0.0283 with increase of knowledge of women who participated in the educational intervention. There was no change in the attitude of women of any of the groups and there was an increase of adherence to colpocytological examination in both groups (p < 0.0001, with greater adherence of women participating in the behavioral group (66.8%. Conclusion: the behavioral and educational interventions by phone were effective in the adherence of women to colpocytological examination, representing important strategies for permanent health education and promotion of care for the prevention of cervical cancer.

To assess the effectiveness of workplace interventions in improving physical activity. EBSCO research database (and all subdatabases). Articles were published from 2000 to 2010 in English, had appropriate designs, and measured employees' physical activity, energy consumption, and/or body mass index (BMI) as primary outcomes. Articles that did not meet the inclusion criteria were excluded. Data extracted included study design, study population, duration, intervention activities, outcomes, and results. Data were synthesized into one table. Results of each relevant outcome including p values were combined. Twelve (60%) of 20 selected interventions reported an improvement in physical activity level, steps, or BMI, and there was one slowed step reduction in the intervention group. Among these, 10 were less than 6 months in duration; 9 used pedometers; 6 applied Internet-based approaches; and 5 included activities targeting social and environmental levels. Seven of 8 interventions with pre-posttest and quasi-experimental controlled design showed improvement on at least one outcome. However, 7 of 12 randomized controlled trials (RCTs) did not prove effective in any outcome. Interventions that had less rigorous research designs, used pedometers, applied Internet-based approaches, and included activities at social and environmental levels were more likely to report being effective than those without these characteristics.

Several potential problems have been detected in the safety aspects for the practice of interventional radiology procedures: a) An important increase in the number cases and their complexity and the corresponding increase of installations and specialists involved; b) New X ray systems more sophisticated, with advanced operational possibilities, requiring special skills in the operators to obtain the expected benefits;c) New medical specialists arriving to the interventional arena to profit the benefits of the interventional techniques without previous experience in radiation protection. For that reason, education and training is one of the basic areas in any optimisation programme in radiation protection (RP). the medical field and especially interventional radiology requires actions to promote and to profit the benefit of the new emerging technologies for training (Internet, electronic books, etc). The EC has recently sponsored the MARTIR programme (Multimedia and Audio-visual Radiation Protection Training in Interventional Radiology) with the production of two videos on basic aspects of RP and quality control and one interactive CD-ROM to allow tailored individual training programmes. those educational tools are being distributed cost free in the main European languages. To go ahead with these actions, the EC has decided to promote during 2002, a forum with the main Medical European Societies involved in these interventional procedures. (Author)

Performing an interventional procedure imposes a commitment on interventional radiologists to conduct the initial patient assessment, determine the best course of therapy, and provide long-term care. Patient care before and after an interventional procedure, identification, and management of early and delayed complications of various procedures are equal in importance to the procedure itself. In this second part, we complete the comprehensive, methodical review of pre-procedural care and patient preparation before vascular and interventional radiology procedures.

Development of the World Health Organization's International Classification of Health Interventions (ICHI) is currently underway. Once finalised, ICHI will provide a standard basis for collecting, aggregating, analysing, and comparing data on health interventions across all sectors of the health system. In this paper, we introduce the classification, describing its underlying tri-axial structure, organisation and content. We then discuss the potential value of ICHI for capturing information on met and unmet need for health interventions relevant to people with a disability, with a particular focus on interventions to support functioning and health promotion interventions. Early experiences of use of the Swedish National Classification of Social Care Interventions and Activities, which is based closely on ICHI, illustrate the value of a standard classification to support practice and collect statistical data. Testing of the ICHI beta version in a wide range of countries and contexts is now needed so that improvements can be made before it is finalised. Input from those with an interest in the health of people with disabilities and health promotion more broadly is welcomed.

Lifestyle-related health issues affect the economic position of organizations and contribute to reduced productivity, increased absenteeism and health care costs. To summarize the effectiveness of different workplace health interventions for promoting healthy lifestyle, preventing diseases and reducing health care costs. We searched MEDLINE via Pubmed, EMBASE, Cochrane Library, NelH, HighWire Press and Google Scholar in March 2012. Systematic reviews and meta-analyses of workplace interventions aimed at promoting physical activity, healthy weight and good nutrition were included. Three authors assessed the quality of the reviews and extracted data on methods, interventions, outcomes, results and effect sizes. We identified 15 publications covering a total of 379 original studies. Three systematic reviews found beneficial effects of workplace nutrition interventions on employees' dietary behaviour. Three reviews found multi-component physical activity interventions to be effective in increasing employees' physical activity and fitness. The other activity promotion interventions were less effective regarding physical activity and weight-related outcomes. In terms of weight management, our findings favour multi-component interventions that focus on both physical activity and nutrition over single dietary programmes. Workplace health promotion interventions may improve physical activity, dietary behaviour and healthy weight. There is no evidence of increased efficacy associated with specific intervention types. Workplace health promotion should focus on either physical activity or weight or nutrition behaviour to maximize effectiveness. Best evidence is available for multi-component interventions.

Given a large body of research indicating links between child attachment and later mental health outcomes, interventions that promote children's secure attachment to their caregivers have the potential to contribute to prevention of psychopathology and promotion of well-being. A number of attachment-based interventions have been developed to support parents, enhance caregiving quality, and promote children's attachment security with the aim of improving children's mental health. There is now a growing evidence base to support the efficacy of a number of these interventions. The present literature review and introduction to the special issue on attachment-based interventions for families with young children describes key aspects of attachment theory and research that form the theoretical and empirical background for attachment-based interventions, and introduces seven case studies illustrating five different attachment-based interventions. The case studies represent a variety of attachment-based models, including both group and individual treatments, and show applications across a range of caregiver contexts. © 2018 Wiley Periodicals, Inc.
