Impact of organic pig production systems on CO2 emission, C sequestration and nitrate pollution
Organic rules for grazing and access to outdoor area in pig production may be met in different ways, which express compromises between considerations for animal welfare, feed self-reliance and negative environmental impact such as greeehouse gas emissions and nitrate pollution. This article compares environmental impact of the main organic pig systems in Denmark. Normally sows are kept in huts on grassland and finishing pigs are being raised in stables with access to an outdoor run. One alternative practised is rearing also the fattening pigs on grassland all year round. The third method investigated was a one-unit pen system mainly consisting of a deep litter area under a climate tent and with restricted access to a grazing area. Using life cycle assessment (LCA) methodology, the emissions of greenhouse gasses of the all free range system was estimated to be 3.3 kg CO2-equivalents kg-1 liveweight pig, which was significantly higher than the indoor fattening system and the tent system yeilding 2.9 and 2.8 kg CO2-eq. kg-1 pig respectively. This was 7-22% higher compared with Danish conventional pig production but, due to the integration of grass-clover in the organic crop rotations these had an estimated net soil carbon sequestration. When carbon sequestration was included in the LCA then the organic systems had lower green house gas emissions compared with the conventional pig production. Eutrophication in nitrate equivalents per kg pig was 21-65% higher in the organic pig systems and acidification was 35-45% higher per kg organic pig compared with the conventional system. We conclude that even though the all free range system theoretically has agro-ecological advantages over the indoor fattening system and the tent system due to a larger grass-clover area this potential is difficult to implement in practice due to problems with leaching on sandy soil. Only if forage can contribute a larger proportion of the pigfeed-uptake may the free range system be economically and environmentally competitive. Improvement of nitrogen cycling and efficiency is the most important factor for reducing the overall environmental load from organic pig meat. Presently a system with pig fattening in stables and concrete covered outdoor runs seems to be the best solution from an environmental point of view
Journal Self-Citation IX: The Power of the Unspoken in Journal Referencing
Publication of articles in so called “reputed” journals and achieving high citation counts for the publications are becoming increasingly important in establishing the scientific achievements of individual scholars and institutions. Given that a journal’s reputation is based predominantly on the extent to which its articles are cited, some editors, reviewers, and journal publishers tend to overtly request references to their articles or journals. This is justifiably found unethical by many of us. However, we shall argue that such explicit requests for referencing is only the tip of the iceberg. There is a widespread, covert understanding among potential authors that unless they cite work of editors and/or have references to the journal where one is submitting a manuscript, the probability of getting the paper accepted for publication may suffer. This consideration is a much more powerful influence than the overt requests some may have experienced as authors. Overt, as well as covert, activities aimed at bumping up individual and journal citations is a dysfunctional result of an increasingly competitive scholarly environment, where the value of success is high, and failure is a very unpleasant option. In the short run, making the community aware of dysfunctional behaviors with respect to citations might help counteract the most blatant exertion of power. However, addressing the more covert use of power requires a more in depth look at ourselves and the way we conduct and assess scholarship. In the long run, the IS field may even need to seriously assess the extent to which our research efforts serve standards primarily internal to our field (similar to rites of other tribes) rather than delivering value to society
Exporting e-Customs to Developing Countries: a Semiotic Perspective
This paper reports on an ongoing study of an initiative to build e-Customs capabilities in eastern Africa. The EU’s customs capability building unit is trying to “export” e-Customs solutions to developing countries in order to strengthen the competiveness of companies based in these countries. Following the international development, e- Customs (with the improved control and traceability possibilities from producer to end consumer) will soon be a prerequisite for participation in international trade. The study is based on a semiotic framework for e-Customs implementations. Previous research has shown how interdependencies between the syntactic, semantic, and pragmatic levels cause problems already within the EU. This research we are now expanding to the introduction of so called Authorized Economic Operators (AEOs) in the East African Community. Since this project has just recently started we have only limited empirical material to load our framework, but initial data shows that the African initiative is trying to implement only parts of the e-Customs solutions that are developed to fit into a different semiotic structure. We can conclude that significant challenges lay ahead in adjusting also the rest of the structure if the initiative is to be successful
The Limits of an Ostrich Policy for Resolving Dialectical Conflicts
In this paper, we analyze the introduction of the Australian Integrated Cargo System (ICS) in order to improve our understanding of eCustoms innovations in Europe, primarily Single Window services. We combine the case study with a theorization based on socially constructed change in networks. The development and diffusion of eCustoms solutions takes place within an elaborate network of businesses, government agencies, and technology providers. We focus on the ongoing dialectics during change in such a network. This means we zoom in on the constant confrontations and conflicts of both interests and understandings of contents, processes, and outcomes of change. These conflicts potential shift change in unintended and unwanted directions, resulting in perceived failure. We critically reflect on the practical lessons that surfaced from the Australian ICS-Import case, where we observed a tendency to avoid facing conflicts, ignoring them, or dismissing them as not important. Our analysis demonstrates that using a dialectic approach can provide substantial insights in eCustoms innovation. We offer a characterization of conflicts and we contribute to the discussion of eCustoms in Europe
Future Strategies for a Click-and-Mortar Bank: A Case Study of the Nordea Group
The case study describes one of the most ambitious and successful attempts of creating a Nordic based large international financial service company, capable of spearheading the transition to the digital economy. Nordea is in the midst of various transformation processes across the organisation due to several years of multiple cross boarder mergers and acquisitions, new composition of the group executive management, increasing thrives towards automation of business processes to reduce costs, and different innovations involving a change of the roles of value network partners. The focus of the study is on the future e-business challenges to the Nordea Group internally, in its collaboration with network partners, in its utilization of the largest number of on-line customers of any bank (3,1 million in 2002), and the implications for the value proposition of the Nordea Group customers
VERDENS BEDSTE STORBYFILM
Når talen falder på storbyfilm, bliver nogle bestemte værker ofte nævnt. Det er film
som Metropolis (1927) af Fritz Lang, Asfaltjunglen (1950) af John Huston, Manhattan
(1979) af Woody Allen og Blade Runner (1982) af Ridley Scott. Fælles for filmene er
for det første, at de tilhører den filmhistoriske kanon i vores del af verden, og for det
andet, at de drager tilskuerens blik til sig med spektakulære billeder af storbyen.
 
Generating Value from Open Government Data
A driving force for change in society is the trend towards Open Government Data (OGD). While the value generated by OGD has been widely discussed by public bodies and other stakeholders, little attention has been paid to this phenomenon in the academic literature. Hence, we developed a conceptual model portraying how data as a resource can be transformed to value. We show the causal relationships between four contextual, enabling factors, four types of value generation mechanisms and value. We use empirical data from 61 countries to test these relationships, using the PLS method. The results mostly support the hypothesized relationships. Our conclusion is that if openness is complemented with resource governance, capabilities in society and technical connectivity, use of OGD will stimulate the generation of economic and social value through four different archetypical mechanisms: Efficiency, Innovation, Transparency and Participation
Benefits and Barriers of University Industry Collaborations from a Researcher\u27s Perspective - Development of Formative Scales and Cluster Analysis
This article extends previous empirical research on the benefits and barriers for researchers in the field of Information Systems (IS) to engage in University-Industry Collaboration (UIC), a term that is used to describe the active engagement of a company or government agency in a joint research project with academics. The objectives and motivations of UIC have been discussed widely and controversially in the literature. We were particularly interested in the perceived benefits and barriers that influence an individual researcher to engage (or not engage) in a joint research project. An in-depth literature analysis showed that a very small number of research articles contain empirical data and that there are serious methodological issues. In order to address these issues, we collected primary data from 328 IS researchers with experience in UIC and conducted an explorative study. We developed parsimonious formative measures for the benefits and barriers of UIC and we found that academic and economic benefits positively influence the intention to conduct UIC in the future, while economic barriers negatively influence the intention to engage in UIC. A cluster analysis found five clusters (groups of researchers) that differ in their perception of benefits and barriers and the future intention to conduct UIC. However, the majority of the researchers have a very high intention to conduct UIC in the future
How IT will challenge existing organizational forms and create Ambient organizations
IT1 is likely to be as important to the way companies will organize
in the future as electricity was to the industrial revolution. IT will
revolutionize entire industries and markets. IT will create new
types of organizations that will surpass and outsmart traditional
organizations. This has been predicted for more than a decade.
But now it is happening especially in the music, newspaper and
publishing industries, and shall see it even more pronounced in
these sectors in the future. But it will not be limited to these
industries; it will influence all types of industry and government
organizations.
Already today, we see many examples of innovative
organizational designs, enhancing organizational effectiveness
and competitiveness.
The paper will briefly discuss the potential of future IT
developments, and will proceed to give a short theoretical
background for why we see a growth in IT-facilitated new
organizational forms. A couple of interesting organizational
design will be mentioned, before we proceed to making the
argument that any business process in principle may be
reengineered, centralized or outsourced in one way or other.
Interesting examples will be presented.
We suggest that future IT will have such a profound impact on
organizational structure going far beyond the traditional ‘virtual
organization’ that it calls for a new organizational concept, which
we have chosen to label the “Ambient Organization’
