The development of mobile telecommunication is emerging as a means of payment by replacing cash and credit cards. Information exchange is regarded as the most important communication system in conforming valid users. The most efficient means of securing information applies cryptography, which relies on small size information and demands its strict management. It is crucial to distribute key to cryptographic communication receiver without exposing key to the third party. The suggested protocol takes authentication and key distribution, which allows session key distribution after user authentication through an authentication center. However, the paper suggests an authentication and key distribution protocol which can be available to smartcard-suing personal communication system. This protocol takes ID-based key distribution method by means of Zero-Knowledge authentication proof which does not reveal secret information to the authentication center.

Aldershot and Burlington: Ashgate, 2006, £45.00, $89.95. "The psychic cloud" (to use Arthur Conan Doyle's expression) that rained revelations upon the enraptured sitters in Victorian Spiritualist séances, refuses to be dispelled by the light of skepticism. Spiritualism, sometimes dismissed as a silly fad, has recently been attracting serious scholarly attention. If two decades ago, the excellent studies of the history and cultural significance of Spiritualism by Janet Oppenheim and Alex Owen were exceptions, the simultaneous appearance of books by Marlene Tromp and Sarah A. Willburn signifies a renewed attempt to discover the answer to an intriguing question: why did so many Victorian men and women spent their time listening to ghostly communications and gazing at "materialized" spirits produced by mostly young, nubile, and enterprising mediums? As Tromp cogently argues, Spiritualism was an important strand in the web of Victorian culture and society. She points out that the mediums and their audiences engaged in a complex refashioning of the key concepts of the Victorian zeitgeist: gender, race, and individual identity. Tromp argues that Spiritualist praxis undermined rigid gender roles and created a space of freedom in which women (and men) could negotiate the thorny issues of sexuality and marriage and eventually reconfigure the Victorian codes of behavior, so that "the more innovative aspects of Spiritualism may have found their way into the mainstream" (72). In support of this thesis, she examines the lives of individual materialization mediums and diverse fictional texts, from sensation novels to ghost stories. Hardly anybody would argue with the claim (amply documented by Owen) that mediumship offered unparalleled opportunities for women to break out of the stifling corset of Victorian femininity. It is equally evident that the movement that erased the boundary between material and spiritual, and whose professed goal was to perform states of possession and multiple identity, undermined what Oscar Wilde (no believer in Spiritualism) called in The Picture of Dorian Gray (1891) "the shallow psychology of those who conceive the Ego in a man as a thing simple, permanent, reliable, and of one essence" (The Complete Works of Oscar Wilde [Hamlyn, 1983] 457). The problem, rather, lies in Tromp's deployment of the postmodern theoretical framework of textual analysis to deal with the stubbornly material scene of the séance. For postmodernism, whether of Jacques Derrida, Jean Baudrillard, or Michel Foucault, sidesteps the problem of representational veracity, focusing on the textual construction of reality. But for Spiritualism, the question of veracity—were the spirits real or not—was absolutely crucial. Bracketing this question as Tromp does creates a distorted image of the fiercely controversial (even within Spiritualism itself) practice of spirit materialization. Tromp abjures any attempt to answer the question of "whether or not the phenomena, such as full-scale 'materialization', are real" (13); when it becomes most [End Page 751] pressing, as in the many instances of fraud and exposure of the materialization mediums, she circumvents it by liberal use of quotation marks. But Spiritualism, unlike religion, staked its authority on the empirical proof of the existence of spirits. Spiritualism was not a "faith," as Tromp calls it, but a misbegotten offspring of positivist science, adopting its rhetoric of material verification. Even a cursory glance at Spiritualist writings shows the obsessive insistence on what Spiritualist Samuel Carter Hall called in 1884 "sure and certain and palpable evidence" of the invisible world (qtd. in Janet Oppenheim, The Other World: Spiritualism and Psychical Research in England, 1850–1914 [1985] 63). Spiritualism's emphasis on sensory experience rather than on inner epiphany accounts for many of its peculiar features: its attraction for so many scientists; its strained relationship with Christianity; and its investment in the gross fraud perpetrated by mediums. Had Tromp investigated the cultural effects of Spiritualism as mediated...
A network community is a special sub-network that contains a group of nodes sharing similar linked patterns. A distributed network community mining problem (D-NCMP) is concerned with finding all such communities from a distributed network. A variety of applications in WWW and ad-hoc networks such as P2P and sensor networks can be formulated into DNCMPs, in which both resources and controls are distributed and/or decentralized. The problem is difficult for some existing methods to deal with because of the fact that their required global topological representations of distributed networks are hard to obtain. In this paper, we present an autonomy oriented computing (AOC) approach [15], in which the nodes and links of a distributed network are distributed among a group of autonomous agents that collectively find global communities hidden in the network. In doing so, the agents maintain only their respective local views and update them through a proposed self-organization process. The effectiveness of the AOC based approach has been validated using network examples.
In this correspondence, we show that the exact number of spatial degrees of freedom (DOF) for a two user nondegenerate (full rank channel matrices) multiple-input-multiple-output (MIMO) Gaussian interference channel with M1, M2 antennas at transmitters 1, 2 and N1, N2 antennas at the corresponding receivers, and perfect channel knowledge at all transmitters and receivers, is min{M1 + M2, N1 + M2, max(M1, N2), max(M2, N1)}. A constructive achievability proof shows that zero forcing is sufficient to achieve all the available DOF on the two user MIMO interference channel. We also show through an example of a share-and-transmit scheme how the gains of transmitter cooperation may be entirely offset by the cost of enabling that cooperation so that the available DOF are not increased.
A decade and a half since the Philippines embarked on a major program of decentralization, the authors of this book have undertaken a detailed examination of all aspects of the nation’s regional dynamics and policies. Their analysis extends to comparable experiences in East Asia, particularly China and Indonesia. The lessons of this book are relevant not only for an audience interested in the Philippines – a large developing nation with a population soon to exceed 100 million people – but also for many other developing countries now embarking on decentralization programs. The book therefore has broad international appeal.
We present what is to our knowledge a novel technique for efficient suppression of the zero-order beam inherent in light patterns projected via phase-only computer-generated holograms (CGHs). Encoding a CGH on a spatial light modulator (SLM) with a limited fill factor produces a disturbing zero-order beam at the optical axis. Here, we propose to derive a CGH, which includes holographic information to project a corrective beam that destructively interferes with the zero-order beam. The CGH for projecting arbitrary light patterns plus a corrective beam are derived using the Gerchberg-Saxton algorithm where the iterations impose both amplitude and phase constraints for the target field pattern at the Fourier plane. As proof of principle, we analyze the viability of the technique by simulating the performance when applied on a practical SLM with a limited fill factor, fixed number of phase-shifting pixels, and wavefront distortion associated with the surface roughness of the SLM.
This talk will discuss the main features of social computing (Web 2.0) applications and the resulting tendencies in the design of social learning environments. The main features of Web 2.0 applications are the decentralization of resources, repositories, and control; the autonomy of learners, contributors (authors), and learning organizations; and the need for active participation --the necessary “glue” to make it all work. The power of social computing applications depends on the number of users and active contributors. In a large scale open environment, the autonomy of learners and authors/course developers is a given and nobody can force anyone to use a particular system. Ease of use, power, and respect for the user autonomy are important features in attracting learners and developers of educational software or learning materials.
The need for autonomy powers a move towards service-oriented or agent-based architectures with clear protocols and languages for interaction between services or agents. Such architectures allow for redundancy and dynamic connection of new functionality or people.
The question about ensuring shared meaning is very important. Dictatorial approaches, however, are unlikely to work in an open environment with autonomous participants. To be viable, a standard has to be simple, usable, rich and easily extensible.
User modeling focus shifts from centralized servers to a libraries of decentralized processes carried out by individual agents or services in context, for the purpose at hand and expressed as policies that can be edited by users. Along with modeling learner features relevant to the domain of interest (e.g. knowledge, experience, affective features), modeling trust and reputation becomes very important to allow appropriate selection of services, and protect the integrity and privacy of user data.
Instructional planning focus shifts to the design of incentive mechanisms to stimulate participation. Various such mechanisms have proved successful in attracting participation of desired type --social comparison, visualizing interpersonal relationships, immediate rewards after desirable actions, and even introducing a virtual currency.
I will illustrate all these tendencies with research I have done with my students and colleagues at the University of Saskatchewan.

We present a general construction of a zero-knowledge proof for an NP relation R(x,w) which only makes a black-box use of a secure protocol for a related multi-partyfunctionality f. The latter protocol is only required to be secure against a small number of "honest but curious" players. As an application, we can translate previous results on the efficiency of secure multiparty computation to the domain of zero-knowledge, improving over previous constructions of efficient zero-knowledge proofs. In particular, if verifying R on a witness of length m can be done by a circuit C of size s, and assuming one-way functions exist, we get the following types of zero-knowledge proof protocols.
This study describes how the function of central government and local governments for social welfare finance should be allocated. Two dimensions are considered to design a policy instrument. One is who provides social welfare service. The other is who burdens the social welfare expenditure. The policy goals toward the decentralization of social welfare finance are to design the optimal allocation of social finance between central government and local governments, and to obtain the territorial justice for social welfare among local governments. The policy instruments toward the decentralization of social welfare finance are as follows. The responsibility of central government for social welfare finance should be expanded. The type of subsidizing social welfare service by central government should be bloc grant. Four dimensions should be considered to design the bloc grant for social welfare. They are the method of finance, the scope of bloc, the ratio of matching by local government, and the performance evaluation.

Diverse Approaches in Healthcare and Education Studies

In recent years, Central American countries have been implementing strategies to expand basic health services to remote and poor rural areas. In most cases, health extension services have been carried out by contracting with nongovernmental organizations (NGOs) and other nonpublic entities to manage or deliver health services. However, contracting with non-state providers has not been easily accepted in these countries as it is often seen as arising out of an ideological desire to privatize publicly financed health services or ultimately to limit or end government involvement in health care. This is what is happening in Honduras, where the Ministry of Health is promoting the extension of services with a community based approach within a decentralization strategy framework. The new health services extension models in Honduras rely on organizational and management arrangements that differ from the traditional Ministry of Health (MOH) health facility model. In particular, the facilities are managed by their communities under different legal and institutional arrangements, depending upon their organizational structures. Their staff are not civil servants, and, as a result, their management has considerably more flexibility in hiring and firing workers. In addition, they have multiple sources of financing. Patients contribute to the financing of these arrangements either with co-payments or pre-payments according to level of income (the sliding scale is determined by the community). The purpose of this study is to identify and compare the costs, efficiency, quality and coverage, as well as the institutional arrangements and organizational structure of the alternative models with one another, and with the traditional services delivery approach of the MOH to determine the feasibility of scaling-up these innovative models of extension of health services. To this purpose, we conducted a health facility survey to collect information on (i) Perceived quality, (ii) Technical quality, (iii) Accessibility (with regards to providers), (iv) Accessibility to communities, and (v) Price/out of pocket payments from users. In addition, the cost of providing key elements of the service package is estimated, including: (i) coverage for vaccination, well-baby care, prenatal care and curative consultations for acute respiratory infection and diarrheic disease, (ii) use of iron supplementation among pregnant women, (iii) knowledge and use of oral re-hydration among women, and (iv) use of vaccination cards for infants. Information on outputs produced have been collected based on these components, as well as their inputs over the last 3 months at each of the facilities. The cost of providing selected components of the basic package of health services in each type of facility was calculated. Results from our analysis show that even though the overall cost of service delivery in the new community models is higher, access to basic health services and quality of care, both technical and perceived, are generally better than in the traditional public health care facilities. Findings also indicate that the new models are more cost efficient than the traditional MOH health care centers suggesting the feasibility of either scaling up these new models and/or alternatively reforming certain aspects of the traditional health care facilities.

Philadelphia: The Jewish Publication Society, 2005. Pp. v + 172. On January 5, 2005, the New York Times published its obituary for Will Eisner, one of the most lauded figures in the world of comics and graphic novels, who had died three days earlier in Fort Lauderdale, Florida, after quadruple bypass surgery. On January 6 the Times ran the following correction: "An obituary of the innovative comic-page illustrator Will Eisner yesterday included an imprecise comparison in some copies between his character The Spirit and others, including Batman. Unlike Superman and some other heroes of the comics, Batman relied on intelligence and skill, not supernatural powers."1 One can only imagine the torrent of e-mails from comics fans pointing out this crucial difference and clucking at the writer's obvious lack of knowledge about the recondite world of superhero comics. It is a difference, of course, that makes even more apt the comparison between Bob Kane's dour, night-stalking masked detective and the dapper, night-stalking masked detective who made Eisner famous in the early 1940s. Both characters were the creations of Jewish comics artists, friends in fact, who attended DeWitt Clinton High School together in the Bronx and grew up during the Depression. It was they and their peers, also primarily Jewish, primarily New Yorkers, who made the comic book form. They helped that form, as Michael Chabon writes in The Amazing Adventures of Kavalier and Clay, "articulate a purpose for itself in the marketplace of ten-cent dreams: to [End Page 463] express the lust for power and the gaudy sartorial taste of a race of powerless people with no leave to dress themselves."2 But Batman and The Spirit also share something else in common. Because they were human rather than superhuman heroes they exemplified a different kind of balance between the "archetypal" and the "typical," Umberto Eco's terms for the mythic and the mimetic dimensions of comic book characters.3 Both Batman and The Spirit, even in their earliest incarnations, intimated that comic book protagonists and stories were capable of transcending stereotypes and reflecting temporal progression and psychological depth. This is perhaps one reason why Frank Miller chose Batman as the character with which to remake the image of the comic book superhero in the 1980s. Batman: The Dark Knight Returns presented comic book readers with a fallible hero in a surprisingly self-reflexive formula story. Eisner, on the other hand, retired The Spirit in 1952. In the latter years of The Spirit's twelve-year run Eisner tired of the demands of a formulaic comic strip, and his work evidenced an increasing interest in formal concerns, in applying to his work the visual lessons of Fritz Lang, Orson Welles, and film noir. Eisner's turn to educational and commercial work in the fifties and sixties, though a lucrative and smart career move, was, in a sense, a waiting period—waiting for comic books to catch up to him, waiting for the right opportunity to explore characters and stories in a more innovative manner. That period ended in 1972 when, as he recounted in a 1990 essay in the New York Times Book Review, he attended his first comic-book convention: "I met the new breed of comic cartoonists for the first time. Long-haired, wild-eyed and intense, they spoke the language of comics. It was a language that gave voice to their protest and social ideas. I wanted to be part of the excitement again."4 Inspired by underground and adult comics of the sixties and early seventies, Eisner took up specifically Jewish characters and topics in a new comics form to which he gave the name "graphic novel." As he says in the introduction to Norton's handsome collection of his first three graphic...
Interactive hashing, introduced by Naor, Ostrovsky, Venkatesan, and Yung (J. Cryptol. 11(2):87–108, 1998 ), plays an important role in many cryptographic protocols. In particular, interactive hashing is a major component in all known constructions of statistically hiding commitment schemes and of statistical zero-knowledge arguments based on general one-way permutations/functions. Interactive hashing with respect to a one-way function f is a two-party protocol that enables a sender who knows y = f ( x ) to transfer a random hash z = h ( y ) to a receiver such that the sender is committed to y : the sender cannot come up with x and x ′ such that f ( x )≠ f ( x ′), but h ( f ( x ))= h ( f ( x ′))= z . Specifically, if f is a permutation and h is a two-to-one hash function, then the receiver does not learn which of the two preimages { y , y ′}= h −1 ( z ) is the one the sender can invert with respect to f . This paper reexamines the notion of interactive hashing, and proves the security of a variant of the Naor et al. protocol, which yields a more versatile interactive hashing theorem. When applying our new proof to (an equivalent variant of) the Naor et al. protocol, we get an alternative proof for this protocol that seems simpler and more intuitive than the original one, and achieves better parameters (in terms of how security preserving the reduction is).
Romania's education system is at a cross-road. Important sector reforms initiated after the fall of communism -- including curriculum changes, student assessment, teacher training, finance and governance -- need to continue to improve education outcomes. However, Romania's integration into the European Union (EU) will place new demands on the country's human capital, creating new challenges for the sector. Demand for skilled manpower will increase with the rising share of high-value-added production and services in the economy. These changes will raise the need for a more competitive labor force with new competencies and skills. To meet these demands the Government should (i) increase education efficiency and equity in the context of decentralization by introducing per capita formula financing, optimizing the school network and training education managers; (ii) increase education quality primarily through better management of human resources; (iii) create more opportunities for skills renewal and life long learning; and (iv) increase effectiveness by developing a coherent, strategic plan for reform, planning, administration, and governance of the sector. This note summarizes the findings and conclusions of the World Bank's most recent analytical work on education.
V. S. Naipaul's bookA Way in the World (1994) is perhaps most strikingly about obsession—about historical figures obsessed by an idea: dreams of new worlds, the fulfillment of large schemes, and the universal failure of such visions. In his long chapter “In the Gulf of Desolation: An Unwritten Story,” Naipaul imagines the wasted year that the Venezuelan revolutionary Francisco Miranda spent on the island of Trinidad in 1806, marooned after an abortive insurrection across the gulf on the mainland. Nine years before Miranda's arrival in Port of Spain, Trinidad was part of the Spanish empire, but now it is British. The island is dominated by plantations: “no place for a metropolitan man like Miranda,” writes Naipaul.1 And yet his work turns on the often hidden or forgotten exchanges between metropolitan spaces of empire and subjugated spaces of colonization. At Port of Spain, Miranda is met by General Thomas Hislop, the British governor. “Hislop is a man of jangled nerves,” Naipaul tells readers. And for good reason. The brutal repression of incipient slave revolt—“the hangings and the mutilations”—has raised legal questions back in London. Much of the chapter centers on imagined conversations between Miranda and Hislop. Hislop is deeply troubled by uncertainties, by the shaky foundations of Britain's Trinidad regime and his responsibility for actions, inhumane and possibly illegal, taken to maintain order. Most particularly, he is anxious about the investigation of General Thomas Picton, the island's first British governor, and by Picton's conviction in the court of King's Bench. “Strange,” Hislop observes, “that all the bigger charges of hanging and theft should have been thrown out, and this case of petty theft should have brought Picton down. Signing the order that the very respectable magistrate brought him for the torture of the young mulatto girl.”2 In fact, this glancing reference to an anonymous “young mulatto girl” marks a return, a reworking of themes and characters that Naipaul introduced twenty-five years earlier in The Loss of El Dorado: A History (1969). As he notes, his earlier book “is made up of two forgotten stories,” two moments when his native Trinidad “was touched by ‘history’” or was brought within European historical consciousness.3 The first story marks the final chapter in the search for El Dorado with Sir Walter Raleigh's return to Trinidad in 1617; the second is that of Louisa Calderon, the young mulatto girl whose torture brought Governor Picton to trial and whose case became a cause célèbre. Calderon now appears at the fringes of British history, given a walk-on part in histories of Trinidad.4 Picton is generally remembered not as a colonial governor but for his role in the Peninsular Campaign and as the highest-ranking officer killed at the Battle of Waterloo; his portrait hangs in the National Portrait Gallery, and his heroic death is commemorated by a statue erected in St. Paul's Cathedral.5 In his Nobel Prize lecture for 2001, Naipaul describes growing up without a sense of his own family's historical past: “All children, I suppose, come into the world like that, not knowing who they are. But for the French child, say, that knowledge is waiting. That knowledge will be all around them … In Trinidad, bright boy though I was, I was surrounded by areas of darkness.” Those “areas of darkness … became my subjects,” writes Naipaul, and that darkness sent him “to the documents in the British Museum and elsewhere, to get the true feel of the history of the colony.”6 The “postcolonial” moment has been one of recovery, as well as one for redrawing boundaries and identities. The blurring of cultural and spatial boundaries has led historians, as well as novelists and other writers, to rethink our own work, sending us back to the archives to get “the true feel,” or at least a new sense, of history. As Antoinette Burton explains, “the imperial turn” “is not a turn toward empire so as a return to the between and and the and the of the on to the case of Picton and the cause of Calderon, with new historical questions and of us who work on British have Picton's case legal that an of In my own A Way in the World and it to a to the to the trial the and the the But as historians, our or the documents after the of the and with other and to the story deeply on And Britain's historical is of the of that history, the by Picton's trial In or British about empire, it is on the of empire as a in empire in on the of colonial to the between a of and the of colonial As cause but one in the long and history of colonial one of The and us of the of empire and of the of exchanges between and this the of British in the and metropolitan about the of that by Picton's trial for Louisa Calderon colonial for a the of as observes, metropolitan was on of colonial the of often the between and and the of on was to The Picton's most the of cultural of and that the and of of to be the of and to and The of was The dominated British an of all British in this that the was an and of and not the the of British and French they the most A of in in all the British and of and a was by and the French of with of of and as the Trinidad was of a The island's and the of very with who French the of of and the island to a Spanish Trinidad became an and the slave to was a large of of who The British Trinidad in but after the of was it to the British Trinidad and it the of with the Spanish British in the and French Trinidad a for the of In the of the General Picton in of Trinidad with a he was governor in and to the of Picton and his within the of a thrown into by and the of the the the of or legal to in a by British his of Picton was by a with long that the of the in the of the him or of Picton this to it in of his was the he was brought to after the of on 1806, Picton's case before and a in the court of King's Bench.

While benefiting from the wealth generated by economic reform, China has also faced increasing social and environmental problems. With the restructuring of state enterprises, the previous occupational-based welfare system has been abolished. To decentralize the state's role in social protection while tackling social problems, the Chinese government has tried to experiment with different social measures to diversify welfare financing and provisions. Included in the social experiments are non-governmental organizations and charities. This paper provides a critical analysis of the social context of China since its economic reform, which, we argue, paves the way for the current development of NGOs and charities. This overview of current development of NGOs and charities in China also highlights existing structural problems.
Since the decade of 1939 the mexican governments focussed the health cure of the poor, children and peasants as public health problems. During the decade of 1980 financement, demographic transition, epidemiological transition problems and the prevailing political situation geared to a health services' decentralization. Presently the mexican health system is composed by public organisms, social security services and private health services. This paper examines some of their problems -resources, eficiency, equity, patients' satisfaction and quality- from the social medicine perspective.
The Government of Albania embarked on a comprehensive program to decentralize decision‐making powers with the passage of the Law on Organization and Functioning of Local Governments in 2000. A centerpiece of the policies undertaken to implement that legislation was an unconditional transfer program which, using a formula‐based allocation mechanism, transferred substantial financial resources to the local communes and municipalities beginning in 2002. This paper describes that system and its evolution. It illustrates how the transfer was designed to take into account the transition from a centralized system to a decentralized arrangement for provision of local public services and how the formula has undergone some “fine‐tuning” while retaining its simplicity. Analysis of the outcomes reveals how it has achieved its mandated objective of equalizing resources across local governments; however, it does so while running the risk of substantially discouraging local governments from mobilizing resources of their own.
This paper studies the complexity classes QZK and HVQZK of problems having a quantum computational zero-knowledge proof system and an honest-verifier quantum computational zero-knowledge proof system, respectively. The results proved in this paper include: (a) HVQZK = QZK, (b) any problem in QZK has a public-coin quantum computational zero-knowledge proof system, (c) any problem in QZK has a quantum computational zero-knowledge proof system of perfect completeness, and (d) any problem in QZK has a three-message public-coin quantum computational zero-knowledge proof system of perfect completeness with arbitrarily small constant error in soundness. All the results above are unconditional and do not rely any computational assumptions. For the classes QPZK, HVQPZK, and QSZK of problems having a quantum perfect zero-knowledge proof system, an honest-verifier quantum perfect zero-knowledge proof system, and a quantum statistical zero-knowledge proof system, respectively, the following new properties are proved: (e) HVQPZK = QPZK, (f) any problem in QPZK has a public-coin quantum perfect zero-knowledge proof system, (g) any problem in QSZK has a quantum statistical zero-knowledge proof system of perfect completeness, and (h) any problem in QSZK has a three-message public-coin quantum statistical zero-knowledge proof system of perfect completeness with arbitrarily small constant error in soundness. It is stressed that our proofs are direct and do not use complete promise problems or those equivalents. This gives a unified framework that works well for all of quantum perfect, statistical, and computational zero-knowledge proofs, and enables us to prove properties even on the computational and perfect zero-knowledge proofs for which no complete promise problems are known.
