The Neglect of Power in Recent Framing Research

Abstract: This article provides a critique of recent developments in research examining media frames and their influence. We contend that a number of trends in framing research have neglected the relationship between media frames and broader issues of political and social power. This neglect is a product of a number of factors, including conceptual problems in the definition of frames, the inattention to frames sponsorship, the failure to examine framing contests within wider political and social contexts, and the reduction of framing to a form of media effects. We conclude that framing research needs to be linked to the political and social questions regarding power central to the media hegemony thesis, and illustrate this focus by exploring how framing research can contribute to an understanding of the interaction between social movements and the news media. Examinations of the production, character, and influence of news stories represent an enduring focus of media scholarship. A variety of approaches, including gatekeeping, agenda setting, organizational studies of news work, and analyses of news bias, have explored either the gathering of news or journalism’s political role. In recent decades, a rapidly expanding research literature on news frames has sought to provide a comprehensive perspective on the production, reception, and influence of news texts. This article provides a critique of recent developments in research examining media frames and their influence. We contend that a number of trends in framing research have neglected the relationship between media frames and broader issues of political and social power. This neglect is a product of conceptual problems in the definition of frames, the inattention to frame sponsorship, the failure to examine framing contests within wider political and social contexts, and the reduction of framing to a form of media effects. In keeping with early sociological research on framing (Gitlin, 1980; Tuchman, 1978), we suggest that framing processes need to be examined within the contexts of the distribution of political and social power. We, therefore, call for the integration of framing research with the

Project-Based Organizations, Embeddedness and Repositories of Knowledge: Editorial

Abstract: Project-based organizations refer to a variety of organizational forms that involve the creation of temporary systems for the performance of project tasks (Lundin and Soderholm 1995; DeFillippi 2002). Project-based organizations have received increasing attention in recent years as an emerging organizational form to integrate diverse and specialized intellectual resources and expertise (DeFillippi and Arthur 1998; Hobday 2000; Gann and Salter 2000; Keegan and Turner 2002; Lindkvist 2004). Recent interest in the emerging knowledge economy has reinforced the view that project organizations in their many varieties are a fast and flexible mode of organizing knowledge resources. Project-based organizations can circumvent traditional barriers to organizational change and innovation, since each project is presented as a temporary, relatively short-lived, phenomenon. As such, it does not pose the same threat to vested interests as would the creation of a permanent new department or division. Moreover, project-based organizations allow for low-cost experiments. Because of their limited duration, project-based organizations do not constitute irreversible resource commitments of fixed costs. Hence, companies and other types of organization may launch a variety of ventures through project-based organizations and may terminate unsuccessful ventures at low cost and little disturbance to the organizational sponsor (DeFillippi 2002). Project-based organizations are found in a wide range of industries. These include consulting and professional services (e.g. accounting, advertising, architectural design, law, management consulting, public relations), cultural industries (e.g. fashion, film-making, video games, publishing), high technology (e.g. software, computer hardware, multimedia), and complex products and systems (e.g. construction, transportation, telecommunications, infrastructure). For many of these industries, project-based organizations are employed to meet the highly differentiated and customized nature of demand, where clients frequently negotiate and interact with project organizers over the ofteninnovative design of products and services (Hobday 1998). However, firms in all types of industries are undertaking projects as a growing part of their operations even while their primary ‘productive’ activity might be volume-based or operations-oriented (e.g. Midler 1995; Keegan and Turner 2002). Hobday (2000) refers to these as project-led organizations and Organization Studies 25(9): 1475–1489 ISSN 0170–8406 Copyright © 2004 SAGE Publications (London, Thousand Oaks, CA & New Delhi) 1475 Authors name

Linking emotional intelligence abilities and transformational leadership styles

Abstract: Today's business environment is changing tremendously due to economic forces that result in the redesign of systems to decrease cost, the need to speed up product development and the focused attention on satisfying customers. These conditions have caused organizations to utilize project management to implement strategic initiatives through projects. By utilizing a “big picture” systems approach to analyze how the system components interact, decisions can be made which are in the “best interest” of the overall project. Project management is ideally matched to this business environment. The study addressed 24 project managers and their associated projects in six organizations from varied industries. The results of the study found that a project manager's transformational leadership style has a positive impact on actual project performance, that emotional intelligence ability contributes to a project manager's transformational leadership style and subsequent actual project performance.

A non‐invasive stress assay based upon measurement of free cortisol released into the water by rainbow trout

Abstract: A procedure previously used for sex steroids was adapted to extract free cortisol and cortisone from water samples taken from rainbow trout Oncorhynchus mykiss tanks. Both corticosteroids could be readily detected by radioimmunoassay (RIA), with cortisol being predominant. All stages of the sampling, extraction and RIA procedure were validated for cortisol. An intermittent problem with poor replication was traced to the use of diethyl ether during the extraction procedure, and was overcome by the use of ethyl acetate. Other modifications were also introduced to speed up the procedure. The concentration and time course of release of both corticosteroids were shown to be related to the degree of stress that the fish had been subjected to. It was confirmed that cortisol concentrations in water and estimated cortisol release rates increased in response to handling stress, and that both were correlated with plasma cortisol concentrations. The potential for using water cortisol concentration and release rates to assess the primary stress response of fishes as a non-invasive alternative to blood sampling is discussed.

Nanoelectromechanics of piezoresponse force microscopy

Abstract: To achieve quantitative interpretation of piezoresponse force microscopy (PFM), including resolution limits, tip bias- and strain-induced phenomena and spectroscopy, analytical representations for tip-induced electroelastic fields inside the material are derived for the cases of weak and strong indentation. In the weak indentation case, electrostatic field distribution is calculated using an image charge model. In the strong indentation case, the solution of the coupled electroelastic problem for piezoelectric indentation is used to obtain the electric field and strain distribution in the ferroelectric material. This establishes a complete continuum mechanics description of the PFM contact mechanics and imaging mechanism. The electroelastic field distribution allows signal generation volume in PFM to be determined. These rigorous solutions are compared with the electrostatic point-charge and sphere-plane models, and the applicability limits for asymptotic point-charge and point-force models are established. The implications of these results for ferroelectric polarization switching processes are analyzed.

Radio over fiber for mobile communications

Abstract: Radio over fiber is becoming an increasingly important technology for the in-building wireless market. The dynamic range requirements and optimum choice of laser are identified for this application. Furthermore, a novel architecture based on switched radio over fiber is proposed, which gives important benefits in terms of design, installation and operation of the systems used.

Narcissistic Features in Young Adolescents: Relations to Aggression and Internalizing Symptoms

Abstract: Recent research and theory suggest narcissistic features contribute to aggression in adults. The present study examined the association of narcissistic features with aggression and internalizing symptoms in 233 students of 5th‐8th grade at three inner-city schools. A factor analysis of the Narcissistic Personality Inventory in this sample revealed three factors: Adaptive Narcissism, Exploitativeness, and Exhibitionism. Regression analyses were used to predict the association of these three narcissistic features with self-, teacher-, and peer-reported aggression and self-reported internalizing symptoms. Results indicate narcissistic exploitativeness positively predicted self-reported proactive aggression, and narcissistic exhibitionism positively predicted internalizing symptoms. Narcissism and self-esteem interacted to predict teacher-reported aggression and self-reported internalizing symptoms. Results are discussed in the context of existing theories of narcissism, threatened egotism, and self-perception bias.

Effects of ionising radiation exposure on plants, fish and mammals: relevant data for environmental radiation protection

Abstract: In order to develop a framework for the assessment of the environmental impact of radiation, it is necessary to establish the relationship between exposure (dose rate, accumulated dose) and the effects that may be induced in plants and animals. With this purpose in mind, the data available on effects induced by ionising radiation in various wildlife groups have been reviewed as part of the FASSET project. This paper has highlighted that the available information on the effects of low dose rate, continuous irradiation ( 10(3) microGy h(-1) sustained for a large fraction of the lifespan.

Effectiveness of collaborative problem solving in affectively dysregulated children with oppositional-defiant disorder: initial findings.

Abstract: Oppositional-defiant disorder (ODD) refers to a recurrent pattern of negativistic, defiant, disobedient, and hostile behavior toward authority figures. Research has shown that children with ODD and comorbid mood disorders may be at particular risk for long-term adverse outcomes, including conduct disorder. In this study, the authors examined the effectiveness of a cognitive–behavioral model of intervention—called collaborative problem solving (CPS)—in comparison with parent training (PT) in 47 affectively dysregulated children with ODD. Results indicate that CPS produced significant improvements across multiple domains of functioning at posttreatment and at 4-month follow-up. These improvements were in all instances equivalent, and in many instances superior, to the improvements produced by PT. Implications of these findings for further research on and treatment selection in children with ODD are discussed.

Career communities: a preliminary exploration of member-defined career support structures

Abstract: This paper explores the concept of career communities: social structures that provide career support and frequently transcend the boundaries of any single organization. The theoretical background notes the convergence of a number of different perspectives from both career development and organization studies, pertaining to the social contextualization of careers. The methodology involved eliciting expressions of the (individual) subjective career from the members of three potential career communities, and then exploring (communal) inter-subjective interpretations in focus groups. Our results suggest that career communities typically involve a hybrid of types rather than any one pure type. Preliminary support is found for the view that career communities facilitate career support, sensemaking and learning. The results invite further research into career communities and have implications for organizational behavior and human resource management, suggesting greater appreciation of the extra-organizational as well as intra-organizational communities in which careers develop.

Monitoring red squirrels Sciurus vulgaris and grey squirrels Sciurus carolinensis in Britain

Abstract: 1. In Britain, five indirect methods have been used to survey for the presence of red Sciurus vulgaris and grey squirrels S. carolinensis and to monitor population trends through time. These are: visual counts along line transects, the use of hair tubes, counts of dreys, cone line feeding transects in conifer forests and feeding signs on whole maize bait at feeding stations. 2. Drey counts and cone feeding transects cannot differentiate between red and grey squirrels and are not suitable for areas where both species may be present. Hair tubes require expertise and facilities to identify hairs to species, and the relationship between tube visits and animal density in different habitats is only known for red squirrels in Sitka spruce Picea sitchensis dominated plantations. Visual counts along line transects are the simplest method to do and require little equipment. However, in general, few squirrels are seen in a single count which leads to difficulties in estimating densities. 3. In this paper we present data from several studies carried out in Britain to illustrate the type of data that may be collected, and to evaluate their accuracy and precision with which they could detect population change. Hair tube lines and drey counts required the fewest number of samples to detect population change. When effort was also considered, visual transects and drey counts were more economical. However, none of the monitoring methods discussed is very precise and it may be best to monitor squirrels only in terms of relative changes in numbers or indices of numbers through time. 4. Our results for red and grey squirrels also illustrated that the number of samples required to detect population change is likely to differ according to the size of the survey area. Monitoring programmes should therefore be carefully planned in relation to spatial scale in order to be able to detect real population changes. Species-specific, quantitative thresholds to determine the significance of detected declines may need to be established for threatened UK mammals and assessed in relation to what would constitute a significant decline and whether it requires management intervention.

Impacts of migratory behaviour on population structure in North Sea plaice

Abstract: Summary 1. Migration is widespread among marine fishes, yet little is known about variation in the migration of individuals within localities, and the consequences for spatial population structure. We tested the hypothesis that variation in the migratory behaviour among plaice ( Pleuronectes platessa L.) in the North Sea could be explained by largescale differences in the speed and directions of the tidal streams, which the fish use as a transport mechanism. 2. We released 752 mature female plaice tagged with electronic data storage tags at eight locations with contrasting tidal flow properties between December 1993 and September 1999. 3. The experiment yielded 20 403 days of data from 145 plaice. Individual tags recorded depth and temperature for up to 512 days. The position of each fish was determined at intervals throughout the liberty period using the tidal location method. 4. The results show that the fish were segregated into three discrete feeding aggregations during the summer non-breeding season. Two clusters were in warm, thermally mixed water in the eastern and western North Sea, respectively, and one was in deeper, cold, thermally stratified water to the north. 5. In the winter spawning period, fish from all three aggregations mixed together in the southern North Sea, and fish from the eastern and northern subunits spawned in the south-eastern North Sea. The only fish that left the North Sea were western subunit plaice that visited spawning grounds in the eastern English Channel. 6. Our results re-affirmed the major role of the tidal streams in the southern North Sea in structuring plaice dispersion, both by providing transport and guidance and by delimiting the extent of distribution due to thermal stratification during the summer. However, plaice from the northern North Sea did not use tidal stream transport. 7. These results confirm the prediction that large-scale variation in migration behaviour can be explained in part by the tidal guidance and transport mechanisms available. They have also revealed features of spatial dynamics not observed previously from a century of conventional tagging experiments and illustrate how the study of individual fish can successfully define the migratory characteristics of populations.

Are we underestimating diabetes-related lower-extremity amputation rates? Results and benefits of the first prospective study.

Abstract: OBJECTIVE —The objective of this study was to accurately determine the incidence of lower-extremity amputation using prospective data collection and to compare the results with those obtained by retrospective methods. RESEARCH DESIGN AND METHODS —The study was carried out over a 3-year period in a large district general hospital covering a clearly defined and relatively static population. All diabetic inpatients with foot problems were identified and followed-up until discharge or death. The demographic and admission details, medical history, investigations, procedures, and history and etiology of the foot lesion were collected twice weekly by a specialist nurse and podiatrist from all relevant wards. Thus, all subjects who underwent amputation could be identified. For comparison, retrospective data were collected from the hospital coding activities database, operating theater log books, anesthetic database, and limb-fitting records. RESULTS —The total population of the region in 2000 was 337,859, of which 9,183 were known to have diabetes. The total number of amputations during the 3-year survey period was 79, of which 45 were major and 34 minor. In our local population, the mean incidence during the survey period (1997–2000) equates to 7.8/100,000 general population and 2.85/1,000 diabetic population for all amputations, 4.5/100,000 general population and 1.62/1,000 diabetic population for major amputations, and 3.3/100,000 general population and 1.23/1,000 diabetic population for minor amputations. The prospective survey detected all lower-extremity amputations identified by the various retrospective methods; however, for the reverse, this was not the case. All of the retrospective methods, including the most commonly used (ICD-9 and OPCS-4 coding), failed to detect all of the cases revealed by the prospective survey (error rate ranging from 4.2 to 90.6%), and between 4.5 and 17.4% of amputations were misclassified. CONCLUSIONS —This study demonstrates the advantages of prospective data collection as a means of determining the incidence of lower-extremity amputations and highlights the limitations of retrospective data collection methods, which underestimate the incidence. In particular, the operating theater records, which have been the gold standard for many surveys, were found to be unreliable. Moreover, we have shown a 47% reduction in the major amputations during the survey period. Thus, we recommend that a prospective audit be incorporated into the activities of the specialist foot care team as a means of assessing and improving clinical care.

Developing and refining a joint management procedure for the multispecies South African pelagic fishery

Abstract: Pilchard (sardine) and anchovy are the main targets of South Africa’s pelagic fishery. This fishery is the country’s second most valuable in monetary terms, and produces the highest annual yield in terms of landed mass (in recent years, a combined catch of the order of 400 000 t). It is the most dynamic of South Africa’s main commercial fisheries, because the species targeted are relatively short-lived, often occur in mixed shoals, and experience large fluctuations in abundance. Mixed shoaling causes operational problems for the fishery, because of the inevitability of juvenile pilchard bycatch (of more value as adults for canning) in the anchovy-directed fishery. This operational interaction implies a trade-off between allowable catches for the two species, and hence necessitates that they are managed together. The development of a joint ‘‘management procedure’’ (sensu IWC) for the two species is described. This provides a framework for quantifying this trade-off, subject to the constraint that acceptable levels of risk of ‘‘collapse’’ are not exceeded for either resource. Important new features incorporated in a revision of the procedure implemented in 2002, which have made appreciably enhanced catches from the resources possible, are described.

Assessing computer skills in Tanzanian medical students: an elective experience.

Abstract: One estimate suggests that by 2010 more than 30% of a physician's time will be spent using information technology tools. The aim of this study is to assess the information and communication technologies (ICT) skills of medical students in Tanzania. We also report a pilot intervention of peer mentoring training in ICT by medical students from the UK tutoring students in Tanzania. Design: Cross sectional study and pilot intervention study. Participants: Fourth year medical students (n = 92) attending Muhimbili University College of Health Sciences, Dar es Salaam, Tanzania. Main outcome measures: Self-reported assessment of competence on ICT-related topics and ability to perform specific ICT tasks. Further information related to frequency of computer use (hours per week), years of computer use, reasons for use and access to computers. Skills at specific tasks were reassessed for 12 students following 4 to 6 hours of peer mentoring training. The highest levels of competence in generic ICT areas were for email, Internet and file management. For other skills such as word processing most respondents reported low levels of competence. The abilities to perform specific ICT skills were low – less than 60% of the participants were able to perform the core specific skills assessed. A period of approximately 5 hours of peer mentoring training produced an approximate doubling of competence scores for these skills. Our study has found a low level of ability to use ICT facilities among medical students in a leading university in sub-Saharan Africa. A pilot scheme utilising UK elective students to tutor basic skills showed potential. Attention is required to develop interventions that can improve ICT skills, as well as computer access, in order to bridge the digital divide.

Drawbacks of endoscopic thoracic sympathectomy

Abstract: Background: Endoscopic thoracic sympathectomy (ETS) has come into widespread use for palmar hyperhidrosis and other complaints of the upper limb and of the head and neck, but there are concerns about its safety. This review highlights the operative complications and long-term side-effects that may occur. Methods: A Medline search was carried out using the terms ‘thoracoscopic sympathectomy’, ‘endoscopic thoracic sympathectomy’ and ‘complications’. References from identified articles were handsearched for further relevant articles. The senior author’s experience and personal communications were also taken into account. Results and conclusion: No death following ETS has ever been reported in the literature, but nine anecdotal fatalities are known, five resulting from major intrathoracic bleeding and three from anaesthetic mishap. Significant intrathoracic bleeding may occur in up to 5 per cent of patients but only a minority require thoracotomy; pneumothorax occurs in 2 per cent of patients and two instances of brain damage are known. In the longer term compensatory hyperhidrosis is extremely common and 1–2 per cent of patients regret having had surgery because of its severity. Horner’s syndrome, on the other hand, is rare. Improvements in instrumentation, adequate training and careful patient selection may help reduce the drawbacks of ETS.

Gender and culture differences in touching behavior.

Abstract: The authors used gender and culture to examine the theory that touching behavior is an expression of dominance. Participants were 120 men and women from Italy, the Czech Republic, and the United States. The authors examined both hand touches and nonhand touches. For hand touches, there was a significant gender-by-culture interaction in that Czech men as a group touched more than any of the other groups. For nonhand touches, Czech and Italian women and Italian men as groups touched significantly more than any of the other groups. Taken in cultural context, these results seem to support the dominance theory for touches with the hand but not for nonhand touches. The authors discussed implications and future directions.

A Comparison of Pimp- and Non-Pimp-Controlled Women

Abstract: A study of 50 incarcerated urban prostitutes finds that 40% have been under the control of a pimp. Pimp-controlled prostitutes are more likely to be single, to have failed to complete high school, to be non-White, to have never held a legitimate job, and to come from exceptionally dysfunctional families. Pimp-controlled prostitutes were younger when they had their first sexual experience, first used illegal drugs, and first engaged in prostitution. Pimp-controlled prostitutes are also more likely to be the victims of violence from customers, suggesting that the pressure to make extra money to support the pimp exposes these women to additional risk. Because of these accumulated adverse experiences, this group may require additional, long-term interventions.

Effectiveness of Different Precipitated Phosphates as Phosphorus Sources for Plants

Abstract: Eleven precipitated phosphates were evaluated as sources of phosphorus (P) for plant growth by comparing their effectiveness with that of monocalcium phosphate, a source of water-soluble P that is generally considered to be fully plant available. The precipitated phosphates comprised struvites recovered from waste water discharges (mainly magnesium ammonium phosphate), laboratory synthesised struvites, a synthetic iron phosphate and a recovered calcium phosphate. Precipitating phosphates in these forms could be a way for removing P from waste water before it is discharged to rivers, so reducing the risk of eutrophication. Application to agricultural land would be one potential use for such phosphates. Evaluation was by pot experiments with a sandy loam soil and with a sandy clay loam soil using perennial ryegrass as the test crop. The soils differed in pH (6.6 and 7.1) and in Olsen P (28 and 11 mg L -1 ). Measured variables were grass dry-matter (DM) yield and grass P concentration which were used to calculate offtake of P in the harvested grass. DM yields of ryegrass and P offtakes given by the synthetic and recovered struvites were not significantly different statistically either between themselves or to MCP applied at the same rate. On this basis these struvites could be used to recycle P to similar soils and the effect of the P on crop yield should be similar to that of MCP

Criteria for the Interpretation of Cocaine Levels in Human Biological Samples and Their Relation to the Cause of Death

Abstract: The determination that cocaine is directly responsible for the immediate cause of death should be considered only when there is a reasonably complete understanding of the circumstances or facts surrounding the death. Another, more obvious and immediate cause of death must be absent, or, at least cocaine must be shown to be a significant contributing factor in the chain of medical findings that lead directly to the immediate cause of death. Not all death investigation requires the sequential steps described in this paper, but these steps must be considered early on in the investigation whenever there is scene, investigational, medical or a historical basis to believe that cocaine is directly related to the cause of death. A relatively high profile death when cocaine is known to be involved, or a death involving unusual behavior on the part of the deceased with police involvement are examples where these considerations may well apply. Information needs to be obtained as soon as possible to have the highest chance of successfully documenting the toxicologic basis for the diagnosis. These facts would include, but would not necessarily be limited to, a scene investigation (whenever possible), a careful review of the investigative reports from all involved agencies, the initial core temperature of the body as well as that of the environment at the time of the collapse or death, the past medical history of the individual, and the results of a complete forensic autopsy and toxicologic studies. Knowledge of and an understanding of the current relevant forensic literature on this subject should be available to the reviewer prior to any interpretation of the significance of cocaine upon a specific death.

Metal effects on soil invertebrate feeding: measurements using the bait lamina method.

Abstract: Heightened concerns regarding the protection of terrestrial ecosystems at a national level has increased the need to develop a suite of indicators capable of assessing the quality, integrity and fertility of soils. Of the assays currently available, tests that measure aspects of soil function and associated parameters are among the most promising, since these integrate effects on soil quality at the highest level of organisation. In this study we describe results of the deployment of an indicator of soil functional integrity (the bait lamina test) that is designed to measure the feeding activity of soil invertebrates. Bait lamina was used at six grassland sites located along a transect from a smelter at Avonmouth (South–West England) used in the EU funded BIOPRINT II project. Results indicated highest bait removal (feeding) at sites furthest from the factory, intermediate feeding activity at intervening sites and extremely low activities at the two sites closest to the smelter. The strong decline in activity for the group of sites closest to the smelter corresponded with increasing metal concentrations suggesting a clear impact of metals on detritivorous invertebrate feeding. Comparisons of the results of the bait lamina study to previous invertebrate survey work suggested that the differences in observed bait removal can be attributed to direct effects of metals on the abundance and biodiversity of key decomposer groups such as earthworms, isopods, molluscs, myriapods, springtails and mites.

The Global Fund to fight AIDS, Tuberculosis and Malaria (GFATM).

Abstract: Most diseases can be controlled. With adequate investment short-term success can almost always be guaranteed in any setting. In the poorest countries however such success will be limited unless the more fundamental causes of poverty and inequity are also addressed. This requires that the world’s poorest be freed from the cycle of debt unfair trade restrictions and undemocratic international policymaking that protects the wealthy at the expense of the poor. The GFATM was created in 2002 in response to growing international concerns about the global impact of these diseases. It is a new financial instrument not an implementing agency. “Its purpose is to attract manage and disburse additional resources through a new private/public initiative that will make a sustainable and significant contribution to the reduction of infections illness and death from these diseases thereby contributing to poverty reduction as part of the Millennium Development Goals.” It is intended to target people and countries in greatest need and supports programmes that have been designed collaboratively involving government donors the private sector and civil society. To date it has disbursed over US$113 million to programmes in 53 countries and committed $1.5 billion over 2 years to 154 programmes in 93 countries. (authors)
