The Data Processing Pipeline for the Herschel-HIFI Instrument
The HIFI data processing pipeline was developed to systematically process
diagnostic, calibration and astronomical observations taken with the HIFI
science instrumentas part of the Herschel mission. The HIFI pipeline processed
data from all HIFI observing modes within the Herschel automated processing
environment, as well as, within an interactive environment. A common software
framework was developed to best support the use cases required by the
instrument teams and by the general astronomers. The HIFI pipeline was built on
top of that and was designed with a high degree of modularity. This modular
design provided the necessary flexibility and extensibility to deal with the
complexity of batch-processing eighteen different observing modes, to support
the astronomers in the interactive analysis and to cope with adjustments
necessary to improve the pipeline and the quality of the end-products. This
approach to the software development and data processing effort was arrived at
by coalescing the lessons learned from similar research based projects with the
understanding that a degree of foresight was required given the overall length
of the project. In this article, both the successes and challenges of the HIFI
software development process are presented. To support future similar projects
and retain experience gained lessons learned are extracted.Comment: 18 pages, 5 figure
Rethinking Workers' Education in Africa
The employment patterns and trends as well as technological
changes have been the most important factors in broadening
the need to rethink workers' education in Africa. Workers'
education more than before, now has a particularly critical
role to play in the various Africa rapidly changing societies
by providing knowledge and information that the working
class people need in order to cope with the changing
conditions. Obviously, the role of workers' education in Africa
assumes greater and greater importance. Wide ranges of
capabilities are required nowadays to deal with emerging
technological challenges.
This shift of emphasis involved in looking at 'wider
education' or 'development education' for increased sociooolitical
and economic roles rather than 'education for
industry' or 'technical utilitarian education', immediately
makes it clear that the task is vast and challenging, requiring
a new perspective.
It is on this basis, that this paper therefore attempts the
possibility of rethinking workers' education as constituting
the most important form of human capital formation in African
countries. Thus a rejuvenated, complicated, comprehensive
and highly integrated facet of workers' education is seen as a
key factor in creating an African labour force that will be
able to play an effective role in the development of the various
African nations
Issues, Challenges and Policy Implications of Social Security Provisions for the Aged in Nigeria
The demographic characteristics of the Nigerian population have shown that the
population of the country is ageing. Interestingly; while the population of these aged
(majority of who are rural dwellers and women) is increasing, the population of the
proportion under age I 5 is decreasing. And by rough estimate, it is expected that the
size of the elderly in Nigeria will growfi·om 6 million in year 2000 to I 6 million by the
year2005.
This has grave consequence for the economic, socio-cultural and medical activities,
which invariably raise the concern to develop a national action plan on how to
manage resources in order to provide social safety-nets for the protection of the aged,
particularly when the traditional family support systems are declining and weakened.
In the light of the above, this paper focuses on the d(fferent problems of the aged in
Nigeria; the provision and availability of social security services; and the
examination of the possibility of having a better social security system that will
enhance the quality of life of eve1y individual regardless of sex and age. On this basis,
the paper therefore, recommends necessary policies/programmes that the Nigerian
government (as well as other national governments in Africa) need to initiate in order
to ensure better safety nets, not only for the aged butfor other categories oft he poor
The demographics of decarbonizing transport: the influence of gender, education, occupation, age, and household size on electric mobility preferences in the Nordic region
Many researchers, policymakers and other stakeholders have explored and supported efforts to transition towards more sustainable forms of low-carbon mobility. Often, discussion will flow from a narrow view of consumer perceptions surrounding passenger vehicles—presuming that they act in rationalist, instrumental, and predictable patterns. In this paper, we hold that a better understanding of the social and demographic perceptions of electric vehicles (compared to other forms of mobility, including conventional cars) is needed. We provide a comparative and mixed methods assessment of the demographics of electric mobility and stated preferences for electric vehicles, drawing primarily on a survey distributed to more than 5,000 respondents across Denmark, Finland, Iceland, Norway and Sweden. We examine how gender influences preferences; how experience in the form of education and occupation shape preferences; and how aging and household size impact preferences. In doing so we hope to reveal the more complex social dynamics behind how potential adopters consider and calculate various aspects of conventional mobility, electric mobility, and vehicle-to-grid systems. In particular, our results suggest that predominantly men, those with higher levels of education in full time employment, especially with occupations in civil society or academia, and below middle age (30 to 45), are the most likely to buy them. However, our analysis also reveals other market segments where electric vehicles may take root, e.g. among higher income females and retirees/pensioners. Moreover, few respondents were orientated towards V2G, independent of their demographic attributes. Our empirical results can inform ongoing discussions about energy and transport policy, the drivers of environmental change, and deliberations over sustainability transitions
Rethinking the spatiality of Nordic electric vehicles and their popularity in urban environments: moving beyond the city?
With a global transition to electric vehicles (EVs) slowly gaining traction, it is expedient to move the debate to issues connected to geography, space, and place. One of these emerging issues is the uptake of EVs in rural areas. This paper provides a spatial state of affairs in the Nordic region and it explores how EVs are perceived and argued to fit within rural-suburban-urban categories by users and potential adopters. To do so, it draws on a mix of original and secondary data: (1) a randomized survey among 4322 respondents, (2) 227 expert interviews, (3) eight focus groups conducted across Iceland, Denmark, Sweden, Finland and Norway, and (4) geographically mapped municipal level vehicle registrations across Norway and Sweden. This data shows that while the uptake primarily takes place in (sub)urban regions, EVs are used in rural environments, partly for self-sufficiency reasons. After acknowledging that individual choices and circumstances dictate final purchase decisions, the paper concludes that planners and researchers should be aware off and, if possible, prevent that a skewed urbanized popularity keeps people elsewhere from looking at EVs as a viable option
Promoting Vehicle to Grid (V2G) in the Nordic region: expert advice on policy mechanisms for accelerated diffusion
Vehicle to Grid (V2G) holds the promise of cheap, flexible, and fast-responding storage through the use of electric vehicle batteries. Unfortunately, infrastructure, battery degradation and consumer awareness are only some of the challenges to a faster development of this technology. This paper offers a qualitative comparative analysis that draws on a subsample of 227 semi-structured interviews on electric vehicles with both transportation and electricity experts from 201 institutions and 17 cities within the Nordic region to discuss the reasoning and arguments behind V2G incentives and policy mechanisms. A frequency analysis of the most coded V2G responses favoured an update of the electricity market regulation – in particular in relation to electricity taxation and aggregator markets – and support for pilot projects. However, the analysis overall implies that V2G, in contrast to EVs, is a technology for the market and by the market. One that will develop on its own over time. More in-depth, our analysis shows the debates around V2G and how its perspective differs per country, pending available frequency capacity and flexible production (hydro power). The paper calls for a further development of flexible electricity markets, support for pilot projects, and attention to information and planning

Reviewing Nordic transport challenges and climate policy priorities: expert perceptions of decarbonisation in Denmark, Finland, Iceland, Norway, Sweden
The five Nordic countries of Denmark, Finland, Iceland, Norway and Sweden have aggressive climate and energy policies in place and are largely on track in their decarbonisation of electricity, heat, and buildings. Transportation and mobility, however, remains a pressing challenge. This study asks: what are the greatest national and regional transport challenges facing Nordic countries? To provide an answer, the authors conducted 227 semi-structured interviews with participants from 201 institutions across seventeen cities within the Nordic region. Those interviewed represent a diverse array of stakeholders involved with transport technology, policy and practice. Although respondents identified 44 distinct transport challenges, the fossil fuel intensity of transport was by far the most frequently mentioned by than two-fifths (42%) of the expert sample. Five other challenges were also mentioned the most frequently by respondents: long travel distances (17%), the state of public transport infrastructure (16%), congestion (15%), population density (10%), and electrification of transport (10%). Interestingly, items such as costs and affordability, energy or transport efficiency, consumer knowledge and awareness, and automobile accidents were mentioned by only 3% (or less). The article concludes by what this heterogeneity and prioritization of challenges means for future Nordic research and policy

Expert perceptions of low-carbon transitions: investigating the challenges of electricity decarbonisation in the Nordic region
The five Nordic countries of Denmark, Finland, Iceland, Norway and Sweden have perhaps the most aggressive and progressive climate, energy, and electricity policies in the world. This study asks: what are the greatest challenges to achieving the region’s low-carbon goals in the domain of electricity? To provide an answer, the authors conducted 227 semi-structured interviews with 257 participants from 201 institutions across seventeen cities within the Nordic region. Those interviewed represent a diverse array of stakeholders involved with electricity technology, policy and practice. Although respondents identified 40 distinct electricity challenges, the integration of renewables was by far the most frequently mentioned (14.5%) of the expert sample. Five other challenges were also mentioned the most frequently by respondents: electrification of transport and other sectors (10.6%), managing intermittency (8.8%), carbon intensity (8.4%), supporting local grids (8.4%), and adequate capacity (8.4%). Interestingly, items such as energy efficiency, consumer awareness, industry, energy security, and public opposition were mentioned by only 1.8% (or less). The article concludes by what this heterogeneity and prioritization of challenges means for future Nordic research and policy
