An investigation into blogging as an opportunity for work-integrated learning for journalism students.

Blogging has become a well-established method of online communication and publication, used by individuals and organisations to disseminate news, ideas and information. In their earlier forms, blogs were used as online diaries, but have now evolved into complex digital environments. This paper argues that these online environments with their associated communities, offer journalism students opportunities for work-integrated learning. It argues that blog environments have the potential to enable students in develop journalism-specific skills, and enhance transferable graduate attributes including creativity, sophisticated communication competencies, initiative and problem solving. It suggests that blogging offers a platform for accessing experiential learning, and as such should be considered within a curriculum for work-integrated learning in the journalism and media subject are

Moisture driven convection on Jupiter: A mechanism to produce the equatorial plumes

Possible roles are explored for moist convection in the production of bright plume features in the Jupiter atmosphere. The features have been observed at least since 1881. A one-dimensional model is developed for a Jovian cloud and the conditions necessary for convection to occur on Jupiter are defined. The model is used to predict the vertical velocity and maximum altitude of moist clouds that are convected over a vertical extent of 100, 10 and 1 km. Convection within the ammonia layer would not produce sufficient buoyancy to sublime from the rising air parcel. Water rising from the 5 bar to 1 bar level could carry enough ammonia to the cooler region to form plume anvils in the stable layer above 700 mbar. If unpolluted during the convection, the water could be the source of high altitude haze above the entire equatorial zone

Spectra of solar proton ground level events using neutron monitor and neutron moderated detector recordings

Recordings on relativistic solar flare protons observed at Sanae, Antarctic, show that the percentage increase in counting rates of the neutron moderated detector (4NMD) is larger than the percentage increase in counting rates of the 3NM64 neutron monitor. These relative increases are described by solar proton differential spectra j sub s(P) = AP(beta). The power beta is determined for each event and the hardnesses of the temporal variations of beta, found for the ground level events (GLE) of 7 May, 1978 and 22 November, 1977

Reconsidering Public Relations’ Infatuation with Dialogue: Why Engagement and Reconciliation Can Be More Ethical Than Symmetry and Reciprocity

Advocates of dialogic communication have promoted two-way symmetrical communication as the most effective and ethical model for public relations. This article uses John Durham Peters’s critique of dialogic communication to reconsider this infatuation with dialogue. In this article, we argue that dialogue’s potential for selectivity and tyranny poses moral problems for public relations. Dialogue’s emphasis on reciprocal communication also saddles public relations with ethically questionable quid pro quo relationships. We contend that dissemination can be more just than dialogue because it demands more integrity of the source and recognizes the freedom and individuality of the source. The type of communication, such as dialogue or dissemination, is less important than the mutual discovery of truth. Reconciliation, a new model of public relations, is proposed as an alternative to pure dialogue. Reconciliation recognizes and values individuality and differences, and integrity is no longer sacrificed at the altar of agreement

Electronics systems test laboratory testing of shuttle communications systems

Shuttle communications and tracking systems space to space and space to ground compatibility and performance evaluations are conducted in the NASA Johnson Space Center Electronics Systems Test Laboratory (ESTL). This evaluation is accomplished through systems verification/certification tests using orbiter communications hardware in conjunction with other shuttle communications and tracking external elements to evaluate end to end system compatibility and to verify/certify that overall system performance meets program requirements before manned flight usage. In this role, the ESTL serves as a multielement major ground test facility. The ESTL capability and program concept are discussed. The system test philosophy for the complex communications channels is described in terms of the major phases. Results of space to space and space to ground systems tests are presented. Several examples of the ESTL's unique capabilities to locate and help resolve potential problems are discussed in detail

Interpreting aggregate wage growth

This paper analyzes the relationship between aggregate wages and individual wages when there is time series variation in employment and in the dispersion of wages. A new and easily implementable framework for the empirical analysis of aggregation biases is developed. Aggregate real wages are shown to contain three important bias terms: one associated with the dispersion of individual wages, a second reflecting the distribution of working hours, and a third deriving from compositional changes in the (selected) sample of workers. Noting the importance of these issues for recent experience in Britain, data on real wages and participation for British male workers over the period 1978-1996 are studied. A close correspondence between the estimated biases and the patterns of differences shown by aggregate wages is established. This is shown to have important implications for the interpretation of real wage growth over this period

Capstan drive transport system for motion picture film

The work presented describes the development of a capstan drive system for the transport of motion picture film. From a model description of the plant and computer aided system design analysis, control algorithms are formulated. The work shows how these relativity complex control algorithms are implemented by making use of the parallel processing capabilities of the transputer. A critical investigation of current film transport methods is undertaken leading to the design and testing of a prototype capstan drive mechanism. The capstan drive system is shown to eliminate problems of sprocket drives and their associated mechanisms. A multi-input multi-output controller is presented using state-space methods of design. The developed control strategies are fully tested on a model of the plant before hardware testing. The control outputs of the system are speed and tension. The final control solution is shown to be a combination of full-state feedback, integral control, and a Kalman filter estimator for the elimination of system disturbances. The transputer implementation of the developed control strategies is presented together with a comparison between simulation and experimental results. It is shown that computational times can be reduced by using multiple transputers and placing computation-intensive sections of the control algorithm on separate processors. Transputer configurations and interconnections are shown. The capstan system has been shown to allow faster printing speeds with improved transport accuracy leading to better quality of the final picture print. The system has been shown to be 'robust' to external disturbances and changes in plant parameters
