When and where do you want to hide? Recommendation of location privacy preferences with local differential privacy
In recent years, it has become easy to obtain location information quite
precisely. However, the acquisition of such information has risks such as
individual identification and leakage of sensitive information, so it is
necessary to protect the privacy of location information. For this purpose,
people should know their location privacy preferences, that is, whether or not
he/she can release location information at each place and time. However, it is
not easy for each user to make such decisions and it is troublesome to set the
privacy preference at each time. Therefore, we propose a method to recommend
location privacy preferences for decision making. Comparing to existing method,
our method can improve the accuracy of recommendation by using matrix
factorization and preserve privacy strictly by local differential privacy,
whereas the existing method does not achieve formal privacy guarantee. In
addition, we found the best granularity of a location privacy preference, that
is, how to express the information in location privacy protection. To evaluate
and verify the utility of our method, we have integrated two existing datasets
to create a rich information in term of user number. From the results of the
evaluation using this dataset, we confirmed that our method can predict
location privacy preferences accurately and that it provides a suitable method
to define the location privacy preference
Simple Vortex States in Films of Type-I Ginzburg-Landau Superconductor
Sufficiently thin films of type-I superconductor in a perpendicular magnetic
field exhibit a triangular vortex lattice, while thick films develop an
intermediate state. To elucidate what happens between these two regimes,
precise numerical calculations have been made within Ginzburg-Landau theory at
and 0.25 for a variety of vortex lattice structures with one flux
quantum per unit cell. The phase diagram in the space of mean induction and
film thickness includes a narrow wedge in which a square lattice is stable,
surrounded by the domain of stability of the triangular lattice at thinner
films/lower fields and, on the other side, rectangular lattices with
continuously varying aspect ratio. The vortex lattice has an anomalously small
shear modulus within and close to the square lattice phase.Comment: 21 pages, 6 figure

Multiple paternity and female sperm usage along egg-case strings of the knobbed whelk, Busycon carica (Mollusca; Melongenidae)
We used genotypic data from three highly polymorphic microsatellite loci (two autosomal and one sex-linked) to examine micro-spatial and temporal arrangements of genetic paternity for more than 1,500 embryos housed along 12 egg-case strings of the knobbed whelk, Busycon carica. Multiple paternity proved to be the norm in these single-dam families, with genetic contributions of several sires (at least 3.5 on average) being represented among embryos within individual egg capsules as well as along the string. Two strings were studied in much greater detail; five and seven fathers were identified, none of which was among the several males found in consort with the female at her time of egg-laying. Each deduced sire had fathered roughly constant proportions of embryos along most of the string, but those proportions differed consistently among fathers. A few significant paternity shifts at specifiable positions along an egg-case string were also observed. Although the precise physical mechanisms inside a female whelk's reproductive tract remain unknown, our genetic findings indicate that successive fertilization events (and/or depositions of zygotes into egg capsules) normally occur as near-random draws from a well-but-not-perfectly blended pool of gametes (or zygotes) stemming from stored ejaculates, perhaps in different titers, of a dam's several mates. © 2006 Springer-Verlag
Implementing social health insurance in Ireland: Report of a meeting and workshop held in Dublin, on December 6th 2010
We considered two basic questions, 'Is it possible to implement Social Health Insurance in Ireland?', and 'How can this be done?'.
Can Social Health Insurance be implemented in Ireland? Our answer is a very definite yes. Furthermore, there would be many opportunities, while working towards this end, to improve the performance of our health care system.
How can it be implemented? This process will need to be actively managed. There are many difficulties in the Irish health services, but also many opportunities. The greatest strengths are the talented, well-trained and very committed staff. Getting and keeping the support of these staff, for the necessary changes in service delivery, will be critical. Ireland has the capacity to make these changes, but without high quality management, a detailed focussed plan for change, and political support, little will happen. Each step in the change needs to be planned to maintain services, improve service delivery, improve service accountability, and improve service governance. Each sector of the service will need someone to lead the change, and mind that service during the change.
Primary care remains under-developed. The HSE plan to develop primary care teams (PCT) has not succeeded. There are several established PCTs which work well. In other areas there are informal arrangements for collaboration, which work well. Overall, there are many useful lessons to learn from the experience so far. Future developments will need to place general practice at the centre of primary care. The mechanisms for doing this will vary from place to place, but need to be developed urgently.
Acute hospitals face a crisis of governance. Maurice Hayes' (1) recent report on Tallaght hospital gives an idea of the scale of the changes needed. Tallaght is, we believe, not atypical, and is reputed to be by no means the worst governed hospital in the system. This, alone, should provide a pressing motive for change. Redesigning Irish hospitals to a new mission of supporting primary care, of supporting care in the community where possible can, and must, be done.
Long-term care for older people is also a challenge. We advise moving to an integrated needs based system with smooth transitions between different degrees of support at home, and different degrees of support in specialized housing facilities including nursing homes. A similar model should apply to other forms of long-term care, for example for people with a substantial disability.
Information systems and management processes both need a major overhaul. The health service remains strikingly under-managed, and fixing this will need a substantial culture change within the services. Wide use of standardized formal project management processes will be vital. There is a separate plan being developed to improve health service IT systems, and implementing this needs to be a high priority.
We have not considered other key sectors, for example mental health, disability services, and social services. This does not mean that these are unimportant, merely that we had limited time, and a great deal to cover

Remobilisation features and structural control on ore grade distribution at the Konkola stratiform Cu-Co ore deposit, Zambia
The Konkola deposit is a high grade stratiform CuâCo ore deposit in the Central African Copperbelt in Zambia. Economic mineralisation is confined to the Ore Shale formation, part of the Neoproterozoic metasedimentary rocks of the Katanga Supergroup. Petrographic study reveals that the copperâcobalt ore minerals are disseminated within the host rock, sometimes concentrated along bedding planes, often associated with dolomitic bands or clustered in cemented lenses and in layer-parallel and irregular veins. The hypogene sulphide mineralogy consists predominantly of chalcopyrite, bornite and chalcocite. Based upon relationships with metamorphic biotite, vein sulphides and most of the sulphides in cemented lenses were precipitated during or after biotite zone greenschist facies metamorphism. New ÎŽ34S values of sulphides from the Konkola deposit are presented. The sulphur isotope values range from â8.7â° to +1.4â° V-CDT for chalcopyrite from all mineralising phases and from â4.4â° to +2.0â° V-CDT for secondary chalcocite. Similarities in ÎŽ34S for sulphides from different vein generations, earlier sulphides and secondary chalcocite can be explained by (re)mobilisation of S from earlier formed sulphide phases, an interpretation strongly supported by the petrographic evidence. Deep supergene enrichment and leaching occurs up to a km in depth, predominantly in the form of secondary chalcocite, goethite and malachite and is often associated with zones of high permeability. Detailed distribution maps of total copper and total cobalt contents of the Ore Shale formation show a close relationship between structural features and higher copper and lower cobalt contents, relative to other areas of the mine. Structural features include the Kirilabombwe anticline and fault zones along the axial plane and two fault zones in the southern limb of the anticline. Cobalt and copper behave differently in relation to these structural features. These structures are interpreted to have played a significant role in (re)mobilisation and concentration of the metals, in agreement with observations made elsewhere in the Zambian Copperbelt

Firm location, interaction, and local characteristics: A case study for Madridâs electronics sector
We use geo-referenced establishment data to estimate parameters of a Gibbs model. The statistical model is used to decompose the conditional intensity of the spatial point process into trend and interaction components. The trend captures covariates related to firmsâ costs, accessibility to public transport infrastructures, to technical universities and to cultural and recreational facilities. The ability to specify a Geyer interaction component captures the existence of additional spillovers providing a deeper insight into inter-establishment spatial dynamics. The results challenge some of the outcomes of the inter-urban industrial location literature, confirming that spatial aggregation compromises results in studies of business location. Firmsâ location decisions are dominated by site costs, with transportation costs being much less of a consideration; universities geographical knowledge spillovers are confirmed for large establishments; and amenities are unlikely to be important location factors
