Flickr: A case study of Web2.0
The “photosharing” site Flickr is one of the most commonly cited examples used to define Web2.0. This paper explores where Flickr’s real novelty lies, examining its functionality and its place in the world of amateur photography. The paper draws on a wide range of sources including published interviews with its developers, user opinions expressed in forums, telephone interviews and content analysis of user profiles and activity. Flickr’s development path passes from an innovative social game to a relatively familiar model of a website, itself developed through intense user participation but later stabilising with the reassertion of a commercial relationship to the membership. The broader context of the impact of Flickr is examined by looking at the institutions of amateur photography and particularly the code of pictorialism promoted by the clubs and industry during the C20th. The nature of Flickr as a benign space is premised on the way the democratic potential of photography is controlled by such institutions. Several optimistic views of the impact of Flickr such as its facilitation of citizen journalism, “vernacular creativity” and in learning as an “affinity space” are evaluated. The limits of these claims are identified in the way that the system is designed to satisfy commercial purposes, continuing digital divides in access and the low interactivity and criticality on Flickr. Flickr is an interesting source of change, but can only to be understood in the perspective of long term development of the hobby and wider social processes
Putting away childish things: incidents of recovery in Tolkien and Haddon
The article discusses the philosophy of author J.R.R. Tolkien. Borrowing concepts from Gerard Manley Hopkins and John Duns Scotus, Tolkien developed the concept of recovery, in which a person is able to interact with the world as though they have never done so before. Using Mark Haddon's novel "The Curious Incident of the Dog in the Night-Time" the article details how recovery can lead people to seeing things differently rather than just glancing at them and accepting it for what it is. The author also uses examples from Tolkien's "Lord of the Rings" series to prove his point
Beyond information: factors in participation in networks of practice, a case study of web management in UK Higher Education
Purpose
To explore the pattern and significance of cross-organizational ties in an emergent professional field, web production in UK Higher Education.
Methodology/Approach
The research is based on in-depth interviews with 21 practitioners and analysis of activity in cross-organizational spaces, such as an online community and a series of annual practitioner conferences on the web in HE (1997-).
Findings
The cross organizational spaces have support and symbolic roles as well as informational ones. They have overlapping but different membership and agendas. Key factors that govern individual participation and so the shape of cross-organizational spaces are differential involvement in technical innovation, degree of organizational embedding or marginality, differences in organizational position and role, orientation towards centralisation or decentralisation and orientation towards marketing or IT. There is some sense of occupational community among web managers, but within that also diversity and a significant fracture line between marketing and IT perspectives on the role. This may explain the lack of formal professionalization. As a more natural boundary practice between organizations than marketing, IT has more public visibility, possibly influencing the course jurisdictional struggles over who should control the web.
Research limitations/implications
As a heavily contextualised study, its detail reflects particular features of HE in the UK at one period as well as specific aspects of the web as a technology. Nevertheless, underlying factors which seem to influence participation and non-participation in cross-organizational networks may be generalisable to many occupations, particularly where knowledge is rapidly changing.
Practical implications
Some suggestions about how cross-organizational knowledge sharing is most effectively supported can be derived from the analysis. IT is a natural focus for cooperation, but there is a risk of this masking the importance of other professional practices. Efforts at formal professionalization may be devisive because people have different professional ambitions and there are individual and organizational benefits in not professionalizing the role formally. New practitioners may be the most active in using extra-organizational networks to assist them to become more embedded locally. Old hands, though they have high prestige and centrality, may increasingly take their own path away from the community. Aspects of local roles such as involvement in innovation or decentralist strategies favour participation in cross-organizational networks.
Originality/value of paper
Most studies of knowledge sharing have focussed on the factors which influence it within an organization, yet cross-organizational sharing is also of importance, even for established professions as the boundaries of organizations become more open. For new occupations cross-organizational ties may be a critical resource, and not only for sharing information or support, but for making sense of what the job is about at the deepest level. The research is also original in analysing a relatively little researched occupational group, those producing web sites for a living. It will be relevant to those interested in online and people centred information seeking, in professionalization and occupational identity
The well-being of British expatriate retirees in southern Europe
This article examines the personal outcomes of overseas residence in later life, by analysing some findings from the first large-scale, comparative study of the retirement of British citizens to southern Europe. Four study areas are compared: Tuscany in Italy, Malta, the Costa del Sol of Spain, and the Algarve region of Portugal. The analysis focuses on the expressed reasons for moving to and residing in the areas, the reported advantages and disadvantages, and the respondents' predictions of whether they would stay or leave in response to adverse and beneficial events.
Overall the subjects give very positive reports, but there are considerable differences among the four areas. The associations of individual variation in well-being with both a person's ‘temporal commitment’ to the area and to facets of their social integration are analysed. The onset of severe incapacity, sufficient to prevent the continued running of a home, is the event most likely to cause people to leave their adopted areas of residence
Understanding the formation of twinned dendrites (‘feather’ grains)
The phenomenon of feather grain growth is interesting from both a theoretical and commercial point of view. Here we report the results of phase-field simulations aimed at understanding the formation of twinned dendrites. We show that, while a competition between oppositely directed capillary and kinetic anisotropies with a simple four-fold symmetry can produce low anisotropy structures such as dendritic seaweed, there is no indication that this can give rise to twinned dendrites. In contrast, adding small components of an anisotropy, with higher order harmonics, can produce features reminiscent of twinned dendrites and may also be able to stabilise the grooved tip morphology
Symmetry-breaking instabilities of convection in squares
Convection in an infinite fluid layer is often modelled by considering a finite box with periodic boundary conditions in the two horizontal directions. The translational invariance of the problem implies that any solution can be translated horizontally by an arbitrary amount. Some solutions travel, but those solutions that are invariant under reflections in both horizontal directions cannot travel, since motion in any horizontal direction is balanced by an equal and opposite motion elsewhere. Equivariant bifurcation theory allows us to understand the steady and time-dependent ways in which a pattern can travel when a mirror symmetry of the pattern is broken in a bifurcation. Here we study symmetry-breaking instabilities of convection with a square planform. A pitchfork bifurcation leads to squares that travel uniformly, while a Hopf bifurcation leads to a new class of oscillations in which squares drift to and fro but with no net motion of the pattern. Two types of travelling squares are possible after a pitchfork bifurcation, and three or more oscillatory solutions are created in a Hopf bifurcation. One of the three oscillations, alternating pulsating waves, has been observed in recent numerical simulations of convection in the presence of a magnetic field. We also present a low-order model of three-dimensional compressible convection that contains these symmetry-breaking instabilities. Our analysis clarifies the relationship between several types of time-dependent patterns that have been observed in numerical simulations of convection
International migration: a panel data analysis of the determinants of bilateral flows
In this paper I empirically investigate the determinants of migration inflows into
fourteen OECD countries by country of origin, between 1980 and 1995. I analyze the
effect on migration of average income and income dispersion in destination and
origin countries. I also examine the impact of geographical, cultural, and
demographic factors as well as the role played by changes in destination countries’
migration policies. My analysis both delivers estimates consistent with the
predictions of the international migration model and generates empirical puzzles
English funding of the Scottish armies in England and Ireland 1640-1648
The rebellion against Charles I's authority that began in Edinburgh in 1637 involved the Scots in successive invasions of England and armed intervention in Ireland. Historians have almost universally taken a negative view of Scottish involvement in these wars, because it has been assumed that the Scottish political leadership sacrificed all other considerations in order to pursue an unrealistic religious crusade. This article suggests that aspects of the Anglo-Scottish relationship need to be reappraised. Using estimates of English payments to the Scots during the 1640s, it will be argued that the Scottish leadership made pragmatic political decisions based on a practical appreciation of the country's military and fiscal capacity. Substantial payouts from the English parliament enabled the Scottish parliamentary regime to engage in military and diplomatic activities that the country could not otherwise have afforded. The 1643 treaty that brought the Scots into the English Civil War on the side of parliament contrasts favourably with the 1647 Engagement in support of the king. It will be shown that, although the English parliament did not honour all of its obligations to the Scots, it does not automatically follow that the alliance was a failure in financial terms

Menstrual cycle patterns of college students in Gorgan-Northeast of Iran: Identify its association with sociodemographic factors
Purpose: The menstrual cycle is used as a sign of women's health. Objective of study is determining the current menstrual patterns of students in Gorgan-Northeast of Iran, and evaluation of affecting factors on the cycle. Material and Methods: The study participants included 106 college student, females aged 18-30 that filled a questionnaire to detect the menstrual pattern, affecting factors on menstrual cycle. Main outcomes of variables compared using ANOVA. Logistic regression was used to model factors for menstrual regularity. Results: The mean ± SD age, menstruation lengths, age at menarche in student girls were 20.58±2.13, 28.02±1.88 and 13.53±1.30, respectively. 59.2% of girls had age 20-25 and 39.8% of these students had normal cycle. Also of 53.4 % of students with normal cycle, 31.8% of students had body mass index 20-24.99. Age at menarche of 56.8% of all participants was 13-14 years. Comparison of regression coefficients between factors and reported menstrual patterns shows similar results for students of all categories of menstrual cycle. Conclusion: This study provides a look at negative correlation of menstrual cycle's length with factors in college students of Gorgan - Northeast of Iran and points to importance of racial differences
