Sourcing the news: Teaching journalism students different approaches to sourcing practices

The experiences of a group of Australian university journalism students from diverse backgrounds are explored as they become involved in producing five editions of a new newspaper for the isolated community of Blackall in the Queensland Outback, 1500km north-west of Sydney. During this learning experience, non-traditional journalistic sourcing methods were trialled. This paper documents the exercise, compares the alternative methods with existing practices identified in the literature, and examines the effects and consequences of the exercise.

Positioning terrorism in management and marketing: Research propositions

Terrorism poses both direct and indirect threats to the operations of the firm. It represents a market imperfection that increases transaction costs and creates barriers to the free flow of goods, affecting potential gains that would occur in the presence of unhindered exchange. Terrorism reflects the risk or actual encounter of violent acts, whose goal is to engender fear, coercion, or intimidation. We investigate terrorism and its association with marketing strategy and operations. Key concepts on terrorism are reviewed and a collection of propositions is offered. We highlight the pivotal roles of sourcing, production, distribution, pricing, communications, and general business strategy as functions influenced by, or capable of influencing, terrorism. Lastly, we offer managerial implications, as well as directions and guidelines for future research.

Manipulating avocado fruit ripening with 1-methylcyclopropene

Previous investigations with 1-methylcyclopropene (1-MCP) on avocado (Persea americana Mill.) fruit have focussed mainly on improving storage life by reducing the severity of disorders causing discolouration of the flesh. Development of 1-MCP and ethylene treatments, which also help control the time to reach the eating ripe stage, may confer additional practical benefits. In this context, the current study investigated the potential of 1-MCP to accurately manipulate ripening of non-stored 'Hass' avocado fruit by treatment before or after ethylene and at different times during ripening. To investigate this, 500 nL L-1 1-MCP was applied within 1 day after harvest, followed by ethylene 0-14 days after 1-MCP. In addition, fruit were treated with ethylene, then 1-MCP 0-8 days after ethylene. Treatment of fruit with 500 nL L-1 1-MCP for 18 h at 20 degreesC provided the maximum effect by increasing the days from harvest to ripe (DTR) from 8 (with no 1-MCP) to 20. Fruit treated with 500 nL L-1 1-MCP for 18 h at 20 degreesC remained insensitive to 100 muL L-1 ethylene applied between 0 and 14 days after 1-MCP for 24 h at 20 degreesC. Ripening of fruit exposed to 100 muL L-1 ethylene for 24 h at 20 degreesC could be delayed by up to 3.3 days by applying 500 nL L-1 1-MCP for 18 h at 20 degreesC up to 2 days after ethylene treatment. However, once the fruit started to soften (sprung) there was little effect of 1-MCP on DTR, compared with no 1-MCP. 1-MCP treatment was associated with increased severity of body rots (caused mainly by Colletotrichum spp.) and stem-end rots (caused mainly by Dothiorella spp.), which was likely due to the increased DTR in these treatments. Significant differences in disease severity were found between orchards (replications), with replicates with low disease severity being less affected by 1-MCP treatment. These results indicate that 1-MCP can delay ripening, but careful sourcing of fruit is required to reduce the risk of diseases in ripe fruit. There is some capacity to delay ripening using 1-MCP after ethylene. There is little potential to control ripening using ethylene after treatment with 500 nL L-1 1-1-MCP, but lower concentrations may be more effective. (C) 2004 Elsevier B.V. All rights reserved.

Business communication in interactions between mainland Chinese and western firms through Hong Kong Chinese intermediaries

Purpose-The paper aims to analyse the nature of business communication and its influence on relationships development between Hong Kong Chinese intermediaries sourcing from Mainland Chinese sellers involved in manufacturing for sale to Western buyer firms. Design/methodology/approach-A case study-driven methodology with purposeful sampling is applied to yield maximum variation in the sampling to elicit underlying tendencies and generative mechanisms that exist within and across the multiple cases of relationships. Findings-The paper finds that Mainland Chinese sellers and Hong Kong Chinese intermediaries tend not to have the close ties that might be expected. Mainland Chinese sellers constrained their use of social information, requiring Hong Kong Chinese intermediaries to use commercial information transfers to evaluate the trustworthiness of their Mainland Chinese partners. An ingroup/outgroup bias exacerbates the modesty bias of the Mainland Chinese and also hinders learning through the transfer of technical information within these Chinese interactions. On the other hand, Western buyers tend not to prefer social information interactions with their Hong Kong Chinese intermediaries, requiring these intermediaries to emphasise commercial information interactions to evaluate the trustworthiness of their Western buyers. Research limitations/implications-This research uses a restricted sample of case study respondents. Representative sampling across multiple contexts will assist in testing the generality of the findings. Practical implications-For the West to source increasingly attractive manufactures from Mainland China, Hong Kong intermediaries will remain fundamentally important even though this creates further interactions. The aggregate of these multiple exchange arrangements is less problematic than would be the case if Western business were to deal directly with the Mainland Chinese. Originality/value-This article sheds light on the nature of business communication interactions in a group of relationships between Hong Kong Chinese intermediaries and Mainland sellers, and buyers from the West. Implications for relationships development among the Chinese and Western actors are identified with propositions framed to guide further investigation.

High resolution provenancing of long travelled dust deposited on the Southern Alps, New Zealand

On 7 February 2000 an atypical orange discolouration of snowfields in the central Southern Alps, New Zealand occurred following the passage of a cold front. Analysis of snow samples identified fine orangey-brown dust mixed with much coarser grey dust. Air parcel forward trajectories from dust sources in southern and central Australia, where dust storms were reported on 4 February 2000, were computed to identify the deposits source. Geochemical analyses of the dust deposit using 26 trace elements, unaffected by regional air pollution and gravitational sorting, indicate that 20% of the dust was sourced from western New South Wales, with 45% from the eastern Eyre Peninsula of South Australia and the remaining 35% was local New Zealand dust. This provenancing approach provides a spatial resolution of long travelled dust sourcing not previously achieved. (c) 2005 Elsevier B.V. All rights reserved.

Reduced genetic diversity and significant genetic differentiation after translocation: Comparison of the remnant and translocated populations of bridled nailtail wallabies (Onychogalea fraenata)

Loss of genetic diversity and increased population differentiation from source populations are common problems associated with translocation programmes established from captive-bred stock or a small number of founders. The bridled nailtail wallaby is one of the most endangered macropods in Australia, having been reduced to a single remnant population in the last 100 years. A translocated population of bridled nailtail wallabies was established using animals sourced directly from the remnant population (wild-released) as well as the progeny of animals collected for a captive breeding programme (captive-bred). The aims of this study were to compare genetic diversity among released animals and their wild-born progeny to genetic diversity observed in the remnant population, and to monitor changes in genetic diversity over time as more animals were released into the population. Heterozygosity did not differ between the translocated and remnant population; however, allelic diversity was significantly reduced across all released animals and their wild-born progeny. Animals bred in captivity and their wild-born progeny were also significantly differentiated from the source population after just four generations. Wild-released animals, however, were representative of the source population and several alleles were unique to this group. Both heterozygosity and allelic diversity among translocated animals decreased over time with the additional release of captive-bred animals, as no new genetic stock was added to the population. Captive breeding programmes can provide large numbers of animals for release, but this study highlights the importance of sourcing animals directly from remnant populations in order to maintain genetic diversity and minimise genetic drift.
