Selected AbstractsFunctional biodiversity of macroinvertebrate assemblages along major ecological gradients of boreal headwater streamsFRESHWATER BIOLOGY, Issue 9 2005JANI HEINOArticle first published online: 3 AUG 200 Summary 1. Biodiversity,environment relationships are increasingly well-understood in the context of species richness and species composition, whereas other aspects of biodiversity, including variability in functional diversity (FD), have received rather little rigorous attention. For streams, most studies to date have examined either taxonomic assemblage patterns or have experimentally addressed the importance of species richness for ecosystem functioning. 2. I examined the relationships of the functional biodiversity of stream macroinvertebrates to major environmental and spatial gradients across 111 boreal headwater streams in Finland. Functional biodiversity encompassed functional richness (FR , the number of functional groups derived from a combination of functional feeding groups and habit trait groups), FD , the number of functional groups and division of individuals among these groups, and functional evenness (FE , the division of individuals among functional groups). Furthermore, functional structure (FS) comprised the composition and abundance of functional groups at each site. 3. FR increased with increasing pH, with additional variation related to moss cover, total nitrogen, water colour and substratum particle size. FD similarly increased with increasing pH and decreased with increasing canopy cover. FE decreased with increasing canopy cover and water colour. Significant variation in FS was attributable to pH, stream width, moss cover, substratum particle size, nitrogen, water colour with the dominant pattern in FS being related to the increase of shredder-sprawlers and the decrease of scraper-swimmers in acidic conditions. 4. In regression analysis and redundancy analysis, variation in functional biodiversity was not only related to local environmental factors, but a considerable proportion of variability was also attributable to spatial patterning of environmental variables and pure spatial gradients. For FR, 23.4% was related to pure environmental effects, 15.0% to shared environmental and spatial effects and 8.0% to spatial trends. For FD, 13.8% was attributable to environmental effects, 15.2% to shared environmental and spatial effects and 5% to spatial trends. For FE, 9.0% was related to environmental variables, 12.7% to shared effects of environmental and spatial variables and 4.5% to spatial variables. For FS, 13.5% was related to environmental effects, 16.9% to shared environmental and spatial effects and 15.4% to spatial trends. 5. Given that functional biodiversity should portray variability in ecosystem functioning, one might expect to find functionally rather differing ecosystems at the opposite ends of major environmental gradients (e.g. acidity, stream size). However, the degree to which variation in the functional biodiversity of stream macroinvertebrates truly portrays variability in ecosystem functioning is difficult to judge because species traits, such as feeding roles and habit traits, are themselves strongly affected by the habitat template. 6. If functional characteristics show strong responses to natural environmental gradients, they also are likely to do so to anthropogenic environmental changes, including changes in habitat structure, organic inputs and acidifying elements. However, given the considerable degree of spatial structure in functional biodiversity, one should not expect that only the local environment and anthropogenic changes therein are responsible for this variability. Rather, the spatial context, as well as natural variability along environmental gradients, should also be explicitly considered in applied research. [source] Applying Organizational Justice: Questionable Claims and Promising SuggestionsINDUSTRIAL AND ORGANIZATIONAL PSYCHOLOGY, Issue 2 2009JERALD GREENBERG With an eye toward promoting applications of organizational justice, I respond to commentaries on my focal article (Greenberg, 2009a). Specifically, I challenge questionable claims regarding (a) characterization of applied research, (b) why we don't conduct more applied justice research, (c) moral versus instrumental rationales for promoting justice, (d) the validity of intervention studies, and (e) interpretations of Lewin's classic observation about the practical value of theory. I also identify and comment upon two suggestions for promoting applied justice research: (a) promoting cooperation between researchers and practitioners and (b) conducting comprehensive, integrative interventions. [source] Applied Research in Accounting: A Commentary,ACCOUNTING PERSPECTIVES, Issue 2 2004ALAN J. RICHARDSON ABSTRACT The mission of Canadian Accounting Perspectives is to provide a forum for "applied research" in accounting, but this key term is not defined. I identify three forms of applied research: (1) the use of existing knowledge to find solutions to current problems; (2) the use of positivist research methods to conduct critical tests between current alternative accounting methods and to identify empirical regularities that contribute to the development of technologies of practice; and (3) the use of disciplined inquiry and action research to develop mid-range theory and generate empirical results that advance the interests or increase the capabilities of an identified community. This third form of applied research may provide the best approach to bridging the schism between academe and practice. [source] Exploring differential attrition rates among system of care evaluation participantsJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 2 2004Kelly N. Rogers The purpose of the present study is to investigate differential attrition rates in terms of both demographic characteristics and initial levels of child functioning of participants in North Carolina's system of care evaluation. Participants included 303 families (78 dropped out of the study, a 26% attrition rate). Families dropped out of the evaluation for three main reasons: refusal to participate, moving, or inability to contact the family. The majority of families who dropped out of the study did so after completing only the baseline interview. Differential attrition did not exist in terms of demographic characteristics, but there was some support for possible differential attrition indicated by initial levels of child functioning in some cases. Additionally, higher parental education level predicted longer participation in longitudinal evaluation. Recommendations and implications for applied research are offered. © 2004 Wiley Periodicals, Inc. J Comm Psychol 32: 167,176, 2004. [source] Deconstructing consumer behaviour: theory and practiceJOURNAL OF CONSUMER BEHAVIOUR, Issue 1 2001Dr David Marsden Abstract This paper challenges the conventional opposition, or distinction, between consumer behaviour theory and practice. This binary dualism, it is argued, is predicated on a simplistic ,either/or' logic that ignores the effects theory and practice have on each other. Furthermore, it obscures a hierarchical relationship between academic researchers and marketing practitioners in which basic research is more dominant and privileged than applied research. In response to these criticisms, an alternative ,both/and' logic is proposed for exploring the interrelationships between consumer behaviour theory and practice and new social relations among consumer researchers.

[source] From fundamental studies of sporulation to applied spore researchMOLECULAR MICROBIOLOGY, Issue 2 2005Imrich Barák Summary Sporulation in the Gram-positive bacterium, Bacillus subtilis, has been used as an excellent model system to study cell differentiation for almost half a century. This research has given us a detailed picture of the genetic, physiological and biochemical mechanisms that allow bacteria to survive harsh environmental conditions by forming highly robust spores. Although many basic aspects of this process are now understood in great detail, including the crystal and NMR structures of some of the key proteins and their complexes, bacterial sporulation still continues to be a highly attractive model for studying various cell processes at a molecular level. There are several reasons for such scientific interest. First, some of the complex steps in sporulation are not fully understood and/or are only described by ,controversial' models. Second, intensive research on unicellular development of a single microorganism, B. subtilis, left us largely unaware of the multitude of diverse sporulation mechanisms in many other Gram-positive endospore and exospore formers. This diversity would likely be increased if we were to include sporulation processes in the Gram-negative spore formers. Spore formers have great potential in applied research. They have been used for many years as biodosimeters and as natural insecticides, exploited in the industrial production of enzymes, antibiotics, used as probiotics and, more, exploited as possible vectors for drug delivery, vaccine antigens and other immunomodulating molecules. This report describes these and other aspects of current fundamental and applied spore research that were presented at European Spores Conference held in Smolenice Castle, Slovakia, June 2004.

Pershing CPT In this second part of a two-part series, a panel of experts indicated that human performance technology (HPT) research is being adequately conducted but not properly used in practice. They stressed a need for more applied research and more extensive use of case studies. They also provided their perspectives about the influences of other fields on HPT, suggesting the need for HPT to align more closely with other disciplines that address issues of human and organizational performance. [source] An Introduction to a Special Issue on Large-Scale Submerged Aquatic Vegetation Restoration Research in the Chesapeake Bay: 2003,2008RESTORATION ECOLOGY, Issue 4 2010Deborah Shafer The Chesapeake Bay is one of the world's largest estuaries. Dramatic declines in the abundance and distribution of submerged aquatic vegetation (SAV) in the Chesapeake Bay over the last few decades led to a series of management decisions aimed at protecting and restoring SAV populations throughout the bay. In 2003, the Chesapeake Bay Program established a goal of planting 405 ha of SAV by 2008. Realizing that such an ambitious goal would require the development of large-scale approaches to SAV restoration, a comprehensive research effort was organized, involving federal and state agencies, academia, and the private sector. This effort differs from most other SAV restoration programs due to a strong emphasis on the use of seeds rather than plants as planting stock, a decision based on the relatively low labor requirements of seeding. Much of the research has focused on the development of tools and techniques for using seeds in large-scale SAV restoration. Since this research initiative began, an average of 13.4 ha/year of SAV has been planted in the Chesapeake Bay, compared to an average rate of 3.6 ha/year during the previous 21 years (1983,2003). The costs of conducting these plantings are on a downward trend as the understanding of the limiting factors increases and as new advances are made in applied research and technology development. Although this effort was focused in the Chesapeake Bay region, the tools and techniques developed as part of this research should be widely applicable to SAV restoration efforts in other areas.

Specific experience is examined regarding integrated water resource management, capacity enhancement in developing countries and writing textbooks. Key lessons include the manner in which applied research and practice inform and enhance basic research, the role of theoretical and conceptual frameworks in guiding applied research, the need to understand the distinction between multidisciplinary and interdisciplinary models and the importance of facilitating evolution from visions, strategies and plans to action. La gestion des ressources et de l'environnement : établir des liens entre l'université et la pratique Cet article examine les récompenses et défis entourant un programme de recherche fondé sur l'interaction entre des éléments de recherche fondamentale et de recherche appliquée. Des expériences particulières en matière de gestion intégrée des ressources en eau, de renforcement des capacités dans les pays en voie de développement, et de rédaction de manuels sont abordées. Les principales leçons que l'on peut tirer comprennent notamment la manière dont la recherche appliquée et la pratique inspirent et mettent en valeur la recherche fondamentale, comment les cadres théoriques et conceptuels éclairent la recherche appliquée, la nécessité de comprendre les différences entre les modèles multidisciplinaires et interdisciplinaires, et l'importance de faciliter la progression des visions, stratégies et plans vers l'action. [source] Evaluation: Using evaluation research to improve medical educationTHE CLINICAL TEACHER, Issue 3 2010Mohsen Tavakol Summary Background:, Evaluation research is a form of applied research that scrutinises how well a particular programme, practice, procedure or policy is operating. Evaluation researchers use both quantitative and qualitative research data to construct a collective picture of the programme under evaluation. Context:, Medical educators need to provide information about a particular programme using the methods of evaluation research in order to make a decision on the potential adoption, improvements and refinements of the programme. Improving curricula and pedagogical methods using these methods may enhance health care education. Innovation:, We provide an overview of the methods of evaluation research in the context of medical education. We discuss the application, general methodology, methods of collecting data and analysis for each type of evaluation research. Implications:, The methods of evaluation research described in this article enable medical educators to gain a comprehensive understanding of evaluation research in the context of medical education. The use of evaluation research findings helps medical educators to make informed decisions regarding a programme and any future actions related to it.

Masters Abstract Recent military battlefield sites are often recorded by accident during geophysical investigations researching into earlier archaeological landscapes. The First World War (Great War) perhaps left its traces like no other war before or since in Europe. For the first time, a large area, some 16,ha in extent, has been surveyed over a modern conflict landscape. The authors have attempted to combine two remote sensing techniques: analysis of contemporary Great War aerial photographs and geophysical prospection techniques. The combination of two different approaches leads to a more comprehensive understanding of the Great War battlefield and an understanding of the value of remote sensing in this new area of applied research.

LOMBARDI Abstract One-tailed statistical tests are often used in ecology, animal behaviour and in most other fields in the biological and social sciences. Here we review the frequency of their use in the 1989 and 2005 volumes of two journals (Animal Behaviour and Oecologia), their advantages and disadvantages, the extensive erroneous advice on them in both older and modern statistics texts and their utility in certain narrow areas of applied research. Of those articles with data sets susceptible to one-tailed tests, at least 24% in Animal Behaviour and at least 13% in Oecologia used one-tailed tests at least once. They were used 35% more frequently with nonparametric methods than with parametric ones and about twice as often in 1989 as in 2005. Debate in the psychological literature of the 1950s established the logical criterion that one-tailed tests should be restricted to situations where there is interest only in results in one direction. ,Interest' should be defined; however, in terms of collective or societal interest and not by the individual investigator. By this ,collective interest' criterion, all uses of one-tailed tests in the journals surveyed seem invalid. In his book Nonparametric Statistics, S. Siegel unrelentingly suggested the use of one-tailed tests whenever the investigator predicts the direction of a result. That work has been a major proximate source of confusion on this issue, but so are most recent statistics textbooks. The utility of one-tailed tests in research aimed at obtaining regulatory approval of new drugs and new pesticides is briefly described, to exemplify the narrow range of research situations where such tests can be appropriate. These situations are characterized by null hypotheses stating that the difference or effect size does not exceed, or is at least as great as, some ,amount of practical interest'. One-tailed tests rarely should be used for basic or applied research in ecology, animal behaviour or any other science. [source] Time to make up your mind: why choosing is difficultBRITISH JOURNAL OF LEARNING DISABILITIES, Issue 1 2003John Harris Summary For many years, the promotion of choice has been a core objective for virtually every service provider working to support people with learning disability. This is confirmed by the 2001 English White Paper Valuing People, A New Strategy for Learning Disability for the 21st Century, which describes choice as one of four key principles at the heart of the UK Government's proposals, and the 2000 review of learning disability services commissioned by the Scottish Executive, People Like Us, which places a similarly high priority on the creation of choice. The present paper gives an overview of our current understanding of the concept of choice. It concludes that our aspirations to promote choice for people with learning disability are undermined by conceptual confusion about the meaning of choice, inappropriate methods for helping people to make choices and an absence of applied research to guide practice in service settings. This review is designed to establish a conceptual framework for examining choice and empowerment for people with learning disability, and to describe the implications for future research and practice.
