Selected AbstractsIs It Time for a New Category of Nursing Diagnosis?INTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 2 2007Geralyn A. Meyer PhD Professional vigilance, the art of "watching out," is the essence of nursing. Vigilance is the mental process that makes the informed nursing actions of assessment, diagnosis, intervention, and evaluation possible and meaningful. Nursing vigilance must be described in our nursing terminology or it risks remaining invisible to others. We propose that the current definition of nursing diagnosis be expanded to include surveillance diagnoses for which the nurse has the responsibility for problem identification and ongoing monitoring. Inclusion of surveillance diagnoses in the NANDA International taxonomy will better reflect the breadth and depth of nursing practice. [source] ECONOMETRIC MODELS OF ASYMMETRIC PRICE TRANSMISSIONJOURNAL OF ECONOMIC SURVEYS, Issue 2 2007Giliola Frey Abstract In this paper, we review the existing empirical literature on price asymmetries in commodities, providing a way to classify and compare different studies that are highly heterogeneous in terms of econometric models, type of asymmetries and empirical findings. Relative to the previous literature, this paper is novel in several respects. First, it presents a detailed and updated survey of the existing empirical contributions on price asymmetries in the transmission mechanism linking input prices to output prices. Second, this paper presents an extension of the traditional distinction between long-run and short-run asymmetries to new categories of asymmetries, such as: contemporaneous impact, distributed lag effect, cumulated impact, reaction time, equilibrium and momentum equilibrium adjustment path, regime effect, regime equilibrium adjustment path. Each empirical study is then critically discussed in the light of this new classification of asymmetries. Third, this paper evaluates the relative merits of the most popular econometric models for price asymmetries, namely autoregressive distributed lags, partial adjustments, error correction models, regime switching and vector autoregressive models. Finally, we use the meta-regression analysis to investigate whether the results of asymmetry tests are not model-invariant and find which additional factors systematically influence the rejection of the null hypothesis of symmetric price adjustment. The main results of our survey can be summarized as follows: (i) each econometric model is specialized to capture a subset of asymmetries; (ii) each asymmetry is better investigated by a subset of econometric models; (iii) the general significance of the F test for asymmetric price transmission depends mainly on characteristics of the data, dynamic specification of the econometric model, and market characteristics. Overall, our empirical findings confirm that asymmetry, in all its forms, is very likely to occur in a wide range of markets and econometric models. [source] Looking through the Lens of Gender: A Postmodern Critique of a Modern Housing ParadigmJOURNAL OF INTERIOR DESIGN, Issue 2 2002Lucinda Kaukas Havenband M.A., M.Phil. ABSTRACT The shift from a modern to postmodern paradigm has dramatically impacted the nature and content of academic inquiry and has opened new categories and methods for research. Interior design has been traditionally critiqued on the basis of aesthetics, formal qualities, function, health and safety, and social/behavioral factors. A postmodern critique expands that criteria to include analysis of how designs may be inscribed with particular ideologies and meanings and consideration of how these meanings may empower or disempower certain groups, or philosophies. In a feminist critique, that analysis considers specifically the ideology of gender. This paper will demonstrate the use of the postmodern deconstructive method of "close reading" in a feminist critique of the Case Study program, a paradigm for modern housing in postwar America. A close reading makes the assumption that the text is not neutral and attempts to discover its biases by thoroughly examining how information has been edited, framed, explained, and constructed. Through this method every aspect of the design process as it has been documented will be scrutinized as texts to examine ideas about roles for women that are constructed through this method; it will not only demonstrate how ideological issues, specifically in this case about gender, can be inscribed within our designs for built spaces, but also provide a greater awareness of our ability as designers to perpetuate, create, or eliminate stereotypes. [source] Two new cases of rank reversals when the AHP and some of its additive variants are used that do not occur with the multiplicative AHPJOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 1 2001Evangelos Triantaphyllou Abstract Many researchers have long observed some cases in which certain ranking irregularities can occur when the original analytic hierarchy process (AHP), or some of its variants, are used. This paper presents two new categories of ranking irregularities which defy common intuition. These ranking irregularities occur when one decomposes a decision problem into a set of smaller problems each defined on two alternatives and the same criteria as the original problem. These irregularities are possible when the original AHP, or some of its additive variants, are used. Computational experiments on random test problems and an examination of some real-life case studies suggest that these ranking irregularities are dramatically likely to occur. This paper also proves that these ranking irregularities are not possible when a multiplicative variant of the AHP is used. Copyright © 2001 John Wiley & Sons, Ltd. [source] The Political Strategies of Winning and Losing Coalitions: Agricultural and Environmental Groups in the Debate over Hypoxia1POLITICS & POLICY, Issue 4 2007Mary Hallock Morris In any debate over a particular policy issue, one must be curious about what will happen when conflicting viewpoints emerge. How do winning and losing coalitions react to potential changes in the status quo? What political strategies are used by the opposing sides of the debate? This article presents a new typology that can be used to assess the political strategies used by winners and losers, ranging from mobilization to venue shifts and issue framing. The typology takes into account the "threat" factor, creating new categories for potential winners and losers. The debate over the dead zone in the Gulf of Mexico is used to illustrate the typology. [source] Concept Shifting and the Radical Product Development ProcessTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 6 2007Victor P. Seidel Radical product development projects, which are undertaken to create new categories of products, present significant challenges to development teams. In such settings existing formal processes may be limited or inappropriate, and objectives may be ambiguous and changing. The generation of a novel product concept early in the process can play an important role in guiding development teams, but the process by which teams later change concepts, as may be required within radical contexts, has merited further research. This study investigated how teams change novel product concepts after initial generation, employing an inductive case-study method drawing from 51 interviews with members of six radical development projects. The empirical results found that concepts were described in terms of concept components,elemental descriptive forms that included verbal stories, verbal metaphors, and physical prototypes. When changes were required to concepts due to new technical or market information, rather than reconsider the overall concept through iteration to earlier product definition stages, teams shifted individual concept components, with a new component replacing a component of similar descriptive form. Over half of concept components observed across cases came after the initial generation of concepts in later elaboration and shifting. Contrary to expectations, development teams maintained reference not only to the revised concept but also to the deferred original concept. The case of a novel electronic book development project is used to illustrate the process, along with evidence of concept shifting across cases. The detailed findings expand our understanding of how formal processes may be augmented in radical innovation settings and how concepts are actually used by development teams in changing circumstances. [source] Structural dynamics and robustness of food websECOLOGY LETTERS, Issue 7 2010Phillip P. A. Staniczenko Ecology Letters (2010) 13: 891,899 Abstract Food web structure plays an important role when determining robustness to cascading secondary extinctions. However, existing food web models do not take into account likely changes in trophic interactions (,rewiring') following species loss. We investigated structural dynamics in 12 empirically documented food webs by simulating primary species loss using three realistic removal criteria, and measured robustness in terms of subsequent secondary extinctions. In our model, novel trophic interactions can be established between predators and food items not previously consumed following the loss of competing predator species. By considering the increase in robustness conferred through rewiring, we identify a new category of species , overlap species , which promote robustness as shown by comparing simulations incorporating structural dynamics to those with static topologies. The fraction of overlap species in a food web is highly correlated with this increase in robustness; whereas species richness and connectance are uncorrelated with increased robustness. Our findings underline the importance of compensatory mechanisms that may buffer ecosystems against environmental change, and highlight the likely role of particular species that are expected to facilitate this buffering. [source] Implementing a national treatment service for dependant smokers: initial challenges and solutionsADDICTION, Issue 2005Tim Coleman ABSTRACT Background Before 1999, few treatment services for nicotine-addicted smokers existed in England. When national treatment services were introduced, those responsible for setting them up liaised closely with primary care health services. Setting up an entirely new national service, treating a new category of patient (smokers motivated to stop) was an ambitious aim and this paper documents the problems encountered in the early stages of this process. Objectives To describe the principal challenges encountered and solutions employed by those setting up the services during the initial period of smoking cessation service implementation. Methods Qualitative, semistructured interviews with 50 smoking cessation staff in two former English health regions conducted in autumn 2001. Findings Two principal factors which slowed the initial development of smoking cessation services were: (i) the lack of a work-force with experience in smoking cessation methods and (ii) the fact that services were set up outside existing primary and secondary care health services in England. As few training courses in smoking cessation were available, many services provided their own in-house training for staff appointed as smoking cessation advisers. Consequently, senior service staff devoted a lot of effort to training new staff which meant that they had less time to spend on other important tasks which were necessary for service implementation. Smoking cessation services needed to develop relationships with primary care health services in order to generate referrals and find venues for the delivery of smoking cessation interventions. Liaising with primary care physicians was time-consuming, however, and some primary care physicians were opposed to the ideas that service staff had for the interface between primary care and smoking cessation services. As new smoking cessation services were not set up within existing primary or secondary health care services, service staff had to spend large amounts of time on this process of negotiation and overcoming scepticism from some primary health care physicians. Conclusions If smoking cessation services are set up in other countries, rapid implementation would be facilitated by ensuring that adequate numbers of health professionals trained in smoking cessation methods are available to staff services. Additionally, locating new smoking cessation services within existing health providers' services may speed up service implementation, but this option may not suit all health systems. [source] Ab initio conformational study of the P6 potential surface: Evidence for a low-lying one-electron-bonded isomerHETEROATOM CHEMISTRY, Issue 2 2007Philippe C. Hiberty The low-lying isomers of the P6 species are investigated at various levels of calculations, ranging from MP2/6-31G(d) to CCSD(T) in triple-zeta basis set involving polarization functions up to f. In addition to the five possible normal-valent isomers, which obey the octet rules, several other conformations are found to be stationary points on the potential energy surface. Among the five normal-valent isomers, the benzvalene structure is found to be the most stable one, in agreement with former studies. The benzene-like D6h planar hexagon is the least stable one, lying 32.3 kcal/mol over benzvalene, and spontaneously distorts to a less symmetrical, nonplanar six-membered ring. Above the benzvalene structure, and lying, respectively, 5.8 and 15.8 kcal/mol higher, the two lowest lying isomers are the prismane and the chair-like forms. This latter conformation, which does not obey the octet rule, exhibits two one-electron PP hemibonds and can be considered as a generic model for a new category of heterobenzene analogs, among which is the recently discovered dimer of diphosphirenyl radical. © 2007 Wiley Periodicals, Inc.

Goldstein Two studies illustrate the functional significance of a new category of prelinguistic vocalizing,object-directed vocalizations (ODVs),and show that these sounds are connected to learning about words and objects. Experiment 1 tested 12-month-old infants' perceptual learning of objects that elicited ODVs. Fourteen infants' vocalizations were recorded as they explored novel objects. Infants learned visual features of objects that elicited the most ODVs but not of objects that elicited the fewest vocalizations. Experiment 2 assessed the role of ODVs in learning word,object associations. Forty infants aged 11.5 months played with a novel object and received a label either contingently on an ODV or on a look alone. Only infants who received labels in response to an ODV learned the association. Taken together, the findings suggest that infants' ODVs signal a state of attention that facilitates learning. [source] Technology options for new nutritional conceptsINTERNATIONAL JOURNAL OF DAIRY TECHNOLOGY, Issue 2 2002Hannu Korhonen Recent advances in the food and nutrition sciences support the concept that the diet has a significant role in the modulation of various functions in the body. The diet and/or its components may contribute to an improved state of well-being, a reduction of risks related to certain diseases and even an improvement in the quality of life. These new concepts have led to the introduction of a new category of health-promoting foodstuffs, i.e. functional foods. The concern about health embraces a number of driving issues, needs and opportunities which may be approached by designing specific diets from various food raw materials. These tailor-made products provide physiological benefits that are targeted at particular consumer groups. The functionality of functional foods is based on bioactive components, which may be contained naturally in the product but usually require formulation by appropriate technologies in order to optimise the desired beneficial properties. To this end, it is often necessary to develop and apply novel technologies, e.g. membrane separation, high hydrostatic pressure and supercritical fluid extraction techniques. Also the minimal processing concept could be employed in this context. This review discusses the current technological options available and the future challenges faced in the area. Particular attention is paid to the exploitation of bovine colostrum and milk-derived bioactive compounds for the development of functional foods. [source] Perceptions and experience of workplace bullying in five different working populationsAGGRESSIVE BEHAVIOR, Issue 6 2003Dawn Jennifer Abstract Whilst aggression in the workplace has been systematically studied in recent years, research into workplace bullying per se still remains quite limited. In this article, we report the findings from an investigation into employees' perceptions of social and organizational work conditions and experiences of bullying at work. Six-hundred-seventy-seven employees from five different working populations (managers, teachers, technicians, call centre operators, and engineers) completed the Workplace Relationships Questionnaire (WRQ). This paper presents the results of the analysis, linking the experiences of bullying and perceptions of social and organizational work conditions. The present findings predictably identify victims and non-bullied participants, and also indicate the existence of a new category of employee affected by the problem of bullying; bullied/non-victims. Bullied/non-victims may provide crucial insights into the ways that company practices and policies impact negatively on the whole workforce. Aggr. Behav. 29:489,496, 2003. © 2003 Wiley-Liss, Inc. [source] INFLUENCE OF OSMOTIC DEHYDRATION ON THE VOLATILE PROFILE OF GUAVA FRUITSJOURNAL OF FOOD QUALITY, Issue 3 2008JORGE A. PINO ABSTRACT The effect of osmotic dehydration (OD) on the volatile compounds of guava fruits was studied. Osmotic treatments were carried out at atmospheric pressure, at continuous vacuum and by applying a vacuum pulse (5 min under vacuum and the remaining time at atmospheric pressure) at different temperatures (30, 40 and 50C) and times (1, 2 and 3 h). The volatile compounds of fresh and dehydrated samples were obtained by simultaneous distillation,extraction, and were analyzed by gas chromatography/mass spectrometry. In general, OD caused changes in the concentration of volatiles, depending on the process conditions. The use of lower temperatures and shorter treatment times can diminish the loss of volatiles with respect to the fresh samples. The greatest damage to volatiles loss is produced at 50C for up to 2 h under both pulsed and continuous vacuum. The lowest total volatiles loss occurred at 30 and 40C for up to 3 h under pulsed vacuum or atmospheric pressure. PRACTICAL APPLICATIONS Consumer demand for high-quality products with freshlike characteristics has promoted the development of a new category, minimally processed fruits and vegetables. Although these products present, as distinguishing features, simplicity in use and convenience, they generally perish more quickly than the original raw material because of tissue damage caused by mechanical operations. The use of osmotic dehydration process has been presented as a tool for the development of minimally processed fruits. The slight water activity reduction promoted by the process may provide stable products with good nutritional and sensorial quality and with characteristics similar to those of the fresh products. The application of minimal processing to tropical fruits can represent an interesting world market. Fruit flavor is an important quality factor that influences consumer acceptability, and for this reason, its study is relevant in the minimally processed food product. [source] The Public Response to Controversial Supreme Court Decisions: The Insular CasesJOURNAL OF SUPREME COURT HISTORY, Issue 3 2005BARTHOLOMEW H. SPARROW In the Insular Cases, the Supreme Court established a new category of areas and persons coming under the sovereignty of the United States. Added to (1) the member states of the Union and (2) the existing territories (and states to be), was (3) territory "belonging to" the United States, but not a part of it. Justice Edward White proposed this doctrine,that territories were of two types, "incorporated" territories, those fit to be states, and non-incorporated territories, to be the property of the United States,in his concurring opinion in Downes v. Bidwell.1 Congress could govern these latter territories as it wished, subject to "fundamental" protections under the Constitution, those protecting individual liberties rather than those granting political participation. [source] TEXTURAL AND MICROSTRUCTURAL PROPERTIES OF BURFI MADE WITH VARIOUS SWEETENERSJOURNAL OF TEXTURE STUDIES, Issue 6 2007S. ARORA ABSTRACT High-intensity low-calorie sweeteners saccharin, acesulfame-K, sucralose and aspartame were used as a replacement for sucrose in the manufacture of burfi. Burfi sweetened with low-calorie sweeteners ranked lower (P < 0.05) but was still acceptable in various textural attributes at all periods of storage in comparison to the control with sucrose. The low hardness, adhesiveness, springiness and accordingly, gumminess and chewiness in burfi samples sweetened with low-calorie sweeteners were because of the lack of compactness. It was evident from the scanning electron microscopy that the compactness of the network in burfi decreased with the use of low-calorie sweeteners. The results of the sensory evaluation have shown the successful use of low-calorie sweeteners in the preparation of burfi with a slight difference in its overall acceptability, thus providing an alternate variety to the health-conscious consumers. PRACTICAL APPLICATIONS The consumption of sweets is an integral part of the Indian dietary system. An estimated 54% of India's milk production is converted into products, both traditional and western, with 50% share of traditional products. But in recent years, the manufacturers are diversifying the production to include the specialty items that cater to specific targeted populations. Diabetic-friendly traditional sweet is a new category for such products, the production of which is being contemplated by many enterprising manufacturers. The results have shown the possibility of using low-calorie sweeteners in the preparation of indigenous dairy products, i.e., burfi. The manufacture of indigenous dairy products with low-calorie sweeteners will provide a successful outlet for traditional milk products, and this will provide an alternate variety to the health-conscious consumers. [source] Under the Law: Legal Consciousness and Radical Environmental ActivismLAW & SOCIAL INQUIRY, Issue 4 2009Erik D. Fritsvold A growing body of sociolegal scholarship focuses the study of law away from formal texts and legal institutions and toward the experiences and perceptions of "everyday" citizens. This study introduces seventeen "radical" environmentalists who engage a repertoire of tactics that includes some actions that involve relatively severe forms of illegality. This research seeks to investigate the role of civil disobedience and lawbreaking within the radical environmental movement and the corresponding legal consciousness of movement actors. Utilizing ethnographic fieldwork and content analysis, this analysis suggests that Ewick and Silbey's (1998) three-tiered model of legal consciousness is an operative starting point, but could be enhanced through theoretical expansion. This study proposes a new category of legal consciousness,Under the Law,that views the law as the protector and defender of a social order that is fundamentally illegitimate. Under the Law is qualitatively different from existing conceptualizations of legal consciousness and reaffirms the mutually constitutive nature of law and society. [source] Reorganizing the Lexicon by Learning a New Word: Japanese Children's Interpretation of the Meaning of a New Word for a Familiar ArtifactCHILD DEVELOPMENT, Issue 5 2002Etsuko Haryu This research investigated how children interpret the meaning of a new word associated with a familiar artifact. The existing literature has shown that syntactic form,class information plays an important role in making this kind of inference. However, this information is not available to Japanese children, because Japanese language does not have a grammatical distinction between count nouns and mass nouns, proper nouns and common nouns, or singular and plural. In Study 1, 12 three,year,old monolingual Japanese children were tested to examine whether they interpreted a new noun associated with a familiar artifact to be a material name or a new label for the object. They interpreted the new word as a new category label for the object, rather than as a name for the material. How children related the new category to the old familiar one was then examined in Studies 2 and 3. The results of Study 2, in which 24 three,year,olds participated, showed that children could flexibly shift between two interpretations using shape information. When the named object had a typical shape for the familiar category, they mapped the new word to a subordinate category. In contrast, when the shape of the named object was atypical, they mapped the new word to a new category that was mutually exclusive to the familiar category by excluding the named object from the familiar category. In Study 3, 12 three,year,olds were tested to examine relative importance of shape and functional information in this inference process. The results of the three studies suggest that children flexibly recruit clues from multiple sources, but the clues are weighed in hierarchical order so that they can determine the single most plausible solution in a given situation when different clues suggest different solutions.
