description: A measurement of the expansion rate of the Universe (that is the Hubble constant, H0) is derived here using the gamma-ray attenuation observed in the spectra of gamma-ray sources produced by the interaction of extragalactic gamma-ray photons with the photons of the extragalactic background light (EBL). The Hubble constant that is determined with our technique, for a Lambda CDM cosmology, is H0=71.8_{-5.6}^{+4.6}(stat)_{-13.8}^{+7.2}(syst) km s^{-1} Mpc^{-1}. This value is compatible with present-day measurements using well established methods such as local distance ladders and cosmological probes. The recent detection of the cosmic gamma-ray horizon (CGRH) from multiwavelength observation of blazars, together with the advances in the knowledge of the EBL, allow us to measure the expansion rate of the Universe. This estimate of the Hubble constant shows that gamma-ray astronomy has reached a mature enough state to provide cosmological measurements, which may become more competitive in the future with the construction of the Cherenkov Telescope Array. We find that the maximum dependence of the CGRH on the Hubble constant is approximately between redshifts 0.04 and 0.1, thus this is a smoking gun for planning future observational efforts. Other cosmological parameters, such as the total dark matter density Omega_m and the dark energy equation of state w, are explored as well.

Two-tank indirect thermal storage designs for solar parabolic trough power plants
Creators: name: Kopp, Joseph E.
Publisher: name: University of Nevada, Las Vegas
Year: 2009

description: The performance of a solar thermal parabolic trough plant with thermal storage is dependent upon the arrangement of the heat exchangers that ultimately transfer energy from the sun into steam. The steam is utilized in a traditional Rankine cycle power plant. The most commercially accepted thermal storage design is an indirect two-tank molten salt storage system where molten salt interacts with the solar field heat transfer fluid (HTF) through a heat exchanger. The molten salt remains in a closed loop with the HTF and the HTF is the heat source for steam generation. An alternate indirect two tank molten salt storage system was proposed where the molten salt was utilized as the heat source for steam generation. A quasi-steady state simulation code was written to analyze the key environmental inputs and operational parameters: solar radiation, solar field size, thermal storage system, heat exchangers, and power block. A base case with no thermal storage was modeled using design parameters from the SEGS VI plant and the effects of solar field size were analyzed. The two differing indirect two-tank molten salt storage designs were modeled and their solar field size and thermal storage capacity were treated as parameters. Results present three days of distinct weather conditions for Las Vegas, Nevada. Annual and monthly electricity generation was analyzed and the results favor the thermal storage case with the solar field HTF interacting with steam. Additionally, the economic trade offs for the three arrangements and speculation of operating strategies that may favor the alternate storage design is discussed.

description: We illustrate the formation of a thin-long structure of heavy nuclei by three-nucleus simultaneous collisions within time-dependent density functional theory. The impact parameter dependence for such formation is systematically demonstrated through clarifications of the difference between binary and ternary collision events. A new method for producing thin-long heavy nuclei in the laboratory is suggested, as well as the possible formation of the thin-long structure in hot dense matter such as that encountered in core collapse supernovae.

description: In this paper, using Hamilton-Jacobi method, we address the tunnelling of fermions in a 4-dimensional Schwarzschild spacetime. Base on the generalized uncertainty principle, we introduce the influence of quantum gravity. After solving the equation of motion of the spin 1/2 field, we derive the corrected Hawking temperature. It turns out that the correction depends not only on the black hole's mass but also on the mass (energy) of emitted fermions. It is of interest that, in our calculation, the quantum gravity correction decelerates the temperature increase during the radiation explicitly. This observation then naturally leads to the remnants in black hole evaporation. Our calculation shows that the residue mass is $\gtrsim M_p/β_0$, where $M_p$ is the Planck mass and $β_0$ is a dimensionless parameter accounting for quantum gravity effects. The evaporation singularity is then avoided.

description: We report a new extraction of nucleon resonance couplings using pi- photoproduction cross sections on the neutron. The world database for the process gn-->pi-p above 1 GeV has quadrupled with the addition of new differential cross sections from the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab in Hall B. Differential cross sections from CLAS have been improved with a new final-state interaction determination using a diagrammatic technique taking into account the SAID phenomenological NN and piN final-state interaction amplitudes. Resonance couplings have been extracted and compared to previous determinations. With the addition of these new cross sections, significant changes are seen in the high-energy behavior of the SAID cross sections and amplitudes.

Implications of a Froissart bound saturation of $γ^*$-$p$ deep inelastic scattering. Part I. Quark distributions at ultra small $x$

description: We argue that the deep inelastic structure function $F_2^{γp}(x, Q^2)$, regarded as a cross section for virtual $γ^*p$ scattering, is hadronic in nature. This implies that its growth is limited by the Froissart bound at high hadronic energies, giving a $\ln^2 (1/x)$ bound on $F_2^{γp}$ as Bjorken $x\rightarrow 0$. The same bound holds for the individual quark distributions. In earlier work, we obtained a very accurate global fit to the combined HERA data on $F_2^{γp}$ using a fit function which respects the Froissart bound at small $x$, and is equivalent in its $x$ dependence to the function used successfully to describe all high energy hadronic cross sections, including $γp$ scattering. We extrapolate that fit by a factor of $\lesssim$3 beyond the HERA region in the natural variable $\ln(1/x)$ to the values of $x$ down to $x=10^{-14}$ and use the results to derive the quark distributions needed for the reliable calculation of neutrino cross sections at energies up to $E_ν=10^{17}$ GeV. These distributions do not satisfy the Feynman "wee parton" assumption, that they all converge toward a common distribution $xq(x,Q^2)$ at small $x$ and large $Q^2$. This was used in some past calculations to express the dominant neutrino structure function $F_2^{ν(\barν)}$ directly in terms of $F_2^{γp}$. We show that the correct distributions nevertheless give results for $F_2^{ν(\barν)}$ which differ only slightly from those obtained assuming that the wee parton limit holds. In two Appendices, we develop simple analytic results for the effects of QCD evolution and operator-product corrections on the distribution functions at small $x$, and show that these effects amount mainly to shifting the values of $\ln(1/x)$ in the initial distributions.

description: Publicly shared numerous types of personal data further increase the possibilities for misuses, especially sensitive data, such as health or biometric data. Our focus is on the phenomenon when people publicly share their or others' personal data related to directed blood donation in order to find donors on the Internet without any protection, which can be the source of identity theft or fake fundraising crimes. To solve this problem and help people to protect their data in this relation, we designed and implemented a possible solution called Shesmu DBDsys, which applies AES-256-GCM encryption to protect and QR code to share data. Shesmu does not store any personal data and ensures that potential donors can only access personal information related to the recipient if they perform a successful donation. We also carried out experimental software analyses to validate the correctness of our implementation and to give proposals, such as the appropriate size of the QR code.

description: There are diverse mechanisms driving the evolution of social networks. A key open question dealing with understanding their evolution is: How various preferential linking mechanisms produce networks with different features? In this paper we first empirically study preferential linking phenomena in an evolving online social network, find and validate the linear preference. We propose an analyzable model which captures the real growth process of the network and reveals the underlying mechanism dominating its evolution. Furthermore based on preferential linking we propose a generalized model reproducing the evolution of online social networks, present unified analytical results describing network characteristics for 27 preference scenarios, and explore the relation between preferential linking mechanism and network features. We find that within the framework of preferential linking analytical degree distributions can only be the combinations of finite kinds of functions which are related to rational, logarithmic and inverse tangent functions, and extremely complex network structure will emerge even for very simple sublinear preferential linking. This work not only provides a verifiable origin for the emergence of various network characteristics in social networks, but bridges the micro individuals' behaviors and the global organization of social networks.

description: In Part I (in this journal) we argued that the structure function $F_2^{γp}(x,Q^2)$ in deep inelastic $ep$ scattering, regarded as a cross section for virtual $γ^*p$ scattering, has a saturated Froissart-bounded form behaving as $\ln^2 (1/x)$ at small $x$. This form provides an excellent fit to the low $x$ HERA data, including the very low $Q^2$ regions, and can be extrapolated reliably to small $x$ using the natural variable $\ln(1/x)$. We used our fit to derive quark distributions for values of $x$ down to $x=10^{-14}$. We use those distributions here to evaluate ultra-high energy (UHE) cross sections for neutrino scattering on an isoscalar nucleon, $N=(n+p)/2$, up to laboratory neutrino energies $E_ν\sim 10^{16}$-$10^{17}$ GeV where there are now limits on neutrino fluxes. We estimate that these cross sections are accurate to $\sim$2% at the highest energies considered, with the major uncertainty coming from the errors in the parameters that were needed to fit $F_2^{γp}(x,Q^2)$. We compare our results to recently published neutrino cross sections derived from NLO parton distribution functions, which become much larger at high energies because of the use of power-law extrapolations of quark distributions to small $x$. We argue that our calculation of the UHE $νN$ cross sections is the best one can make based the existing experimental deep inelastic scattering data. Further, we show that the strong interaction Froissart bound of $\ln^2 (1/x)$ on $F_2^{γp}$ translates to an exact bound of $\ln^3E_ν$ for leading-order-weak $νN$ scattering. The energy dependence of $νN$ total cross section measurements consequently has important implications for hadronic interactions at enormous cms (center-of-mass) energies not otherwise accessible.

description: We demonstrate the modelling of opportunistic networks using the process algebra stochastic HYPE. Network traffic is modelled as continuous flows, contact between nodes in the network is modelled stochastically, and instantaneous decisions are modelled as discrete events. Our model describes a network of stationary video sensors with a mobile ferry which collects data from the sensors and delivers it to the base station. We consider different mobility models and different buffer sizes for the ferries. This case study illustrates the flexibility and expressive power of stochastic HYPE. We also discuss the software that enables us to describe stochastic HYPE models and simulate them.

description: Bundling has become an important operational tool for online retail platforms to attract consumers. Nevertheless, published empirical results on consumer behavior show that a bundle discount negatively influences the consumers’ perceived value of individual component products. We investigate how valuation discounts like these influence the online retail platforms’ decision optimization in bundling. Optimization models for mixed-joint and mixed-leader bundling are developed to analyze this effect. Based on the benchmark model of no-bundling, insightful implications are provided by comparing these three models. It is found that, in specified conditions, mixed-leader bundling outperforms mixed-joint bundling due to the negative effects of valuation discounts. Moreover, when the potential consumer pools of individual components are both large, mixed-joint bundling, which common knowledge considers the most profitable strategy, performs worse than the no-bundling strategy when valuation discounts are taken into account.

description: Исследуется реакция наиболее авторитетных итальянских критиков, писателей и публицистов на присуждение Нобелевской премии по литературе писателям из СССР: в 1958 году Б.Л.Пастернаку, в 1965 году — М.А.Шолохову. Заслуживает особого внимания тот факт, что ключевые романы советской литературы ХХ века «Доктор Живаго» Пастернака и «Тихий Дон» М.А. Шолохова вышли в Италии одновременно, что дало повод к их сравнению в критической литературе. Более того, оба писателя не раз были в числе номинантов на премию: в частности, в 1958 году они оказались невольными соперниками в борьбе за внимание Нобелевского комитета. Тон противопоставлению Пастернака Шолохову задала партийная критика в лице члена Компартии Италии К.Салинари. Суждения критики о художественных достоинствах романа Пастернака не отличались единодушием. Однако в своем большинстве итальянская критика поддержала мнение Нобелевского комитета, присудившего премию Пастернаку «за значительные достижения в современной лирической поэзии, а также за продолжение традиций великого русского эпического романа», отметив, что эта премия в лице Пастернака присуждена всей великой русской поэзии ХХ века.

description: In this paper we consider a family of dynamical systems that we call "arabesques", defined as closed chains of 2-element negative circuits. An $n$-dimensional arabesque system has $n$ 2-element circuits, but in addition, it displays by construction, two $n$-element circuits which are both positive vs one positive and one negative, depending on the parity (even or odd) of the dimension $n$. In view of the absence of diagonal terms in their Jacobian matrices, all these dynamical systems are conservative and consequently, they can not possess any attractor. First, we analyze a linear variant of them which we call "arabesque 0" or for short "A0". For increasing dimensions, the trajectories are increasingly complex open tori. Next, we inserted a single cubic nonlinearity that does not affect the signs of its circuits (that we call "arabesque 1" or for short "A1"). These systems have three steady states, whatever the dimension is, in agreement with the order of the nonlinearity. All three are unstable, as there can not be any attractor in their state-space. The 3D variant (that we call for short "A1\_3D") has been analyzed in some detail and found to display a complex mixed set of quasi-periodic and chaotic trajectories. Inserting $n$ cubic nonlinearities (one per equation) in the same way as above, we generate systems "A2\_$n$D". A2\_3D behaves essentially as A1\_3D, in agreement with the fact that the signs of the circuits remain identical. A2\_4D, as well as other arabesque systems with even dimension, has two positive $n$-circuits and nine steady states. Finally, we investigate and compare the complex dynamics of this family of systems in terms of their symmetries.

description: In this paper, we consider the infinite-dimensional integration problem on weighted reproducing kernel Hilbert spaces with norms induced by an underlying function space decomposition of ANOVA-type. The weights model the relative importance of different groups of variables. We present new randomized multilevel algorithms to tackle this integration problem and prove upper bounds for their randomized error. Furthermore, we provide in this setting the first non-trivial lower error bounds for general randomized algorithms, which, in particular, may be adaptive or non-linear. These lower bounds show that our multilevel algorithms are optimal. Our analysis refines and extends the analysis provided in [F. J. Hickernell, T. Müller-Gronbach, B. Niu, K. Ritter, J. Complexity 26 (2010), 229-254], and our error bounds improve substantially on the error bounds presented there. As an illustrative example, we discuss the unanchored Sobolev space and employ randomized quasi-Monte Carlo multilevel algorithms based on scrambled polynomial lattice rules.

description: We have carried out a new direct search for the CP violating decay KS -> 3pi0 with 1.7 fb^-1 of e+e- collisions collected by the KLOE detector at the phi-factory DAFNE. We have searched for this decay in a sample of about 5.9 x 10^8 KS KL events tagging the KS by means of the KL interaction in the calorimeter and requiring six prompt photons. With respect to our previous search, the analysis has been improved by increasing of a factor four the tagged sample and by a more effective background rejection of fake KS tags and spurious clusters. We find no candidates in data and simulated background samples, while we expect 0.12 standard model events. Normalizing to the number of KS -> 2pi0 events in the same sample, we set the upper limit on BR(KS -> 3pi0 < 2.6 x 10^-8 at 90% C.L., five times lower than the previous limit. We also set the upper limit on the eta_000 parameter, |eta_000 | < 0.0088 at 90% C.L., improving by a factor two the latest direct measurement.

description: There are frequent suggestions that parents of children with Special Educational Needs (SEN) and educational practitioners (practitioners) experience adversarial home-school relationships. Yet there was scope to explore the influence of the perceived nature of children's SENs on socio-emotional issues implicated in these relationships, namely blame and its closely related concept of stigma, in addition to partnership and empathy. Previous literature in this specific area had predominantly focused on parents who had children with the label of Behavioural, Emotional and Social Difficulties (BESD). This provided opportunity to also give voice to parents of children with other SENs in further depth, as well as practitioners. This study therefore investigated socio-emotional aspects of home-school relationships with parents of children with SEN and practitioners. in accordance with a conceptual framework involving blame, stigma. partnership and empathy. Weiner's (1980) attributional model regarding the perceived controllability of stigmas was used as a theoretical lens. Based on an Interpretative Phenomenological Analysis approach, semi-structured interviews were conducted with 22 parents of children with SEN (both with and without the label of BESD), and 15 practitioners. Findings identified how the perceived nature of children's SENs influenced perceptions of controllability, which impacted on experiences of blame, guilt and stigma. These experiences framed interest in 'labels' of SEN for children. With regards to partnership and empathy. the following factors were influential: practitioner approachability and trustworthiness, elements implicated in social class, head teacher approaches to SEN, and whether practitioners had children with SEN themselves. This thesis highlights the importance of eliciting the experiences of parents of children with varying labels of SEN, who had very different stories to tell, whilst also recognising the need to give voice to both parents and professionals when considering socio-emotional aspects of home-school relationships. The need for wider practitioner investment in, and socio-emotional understanding of, the 'experiences of parents is also considered.
Diversity issues in recruitment and retention of clients for parenting classes
Creators: name: Davis, Rachel Elizabeth
Publisher: name: University of Nevada, Las Vegas

description: Parenting skills classes are an effective means of preventing and remediating juvenile delinquency, youth violence, and child maltreatment. In particular, juvenile delinquency and child maltreatment disproportionately affect low-income African American families. Unfortunately, data from most parenting classes suggest dismal attendance and participation rates for racial- and ethnic-minorities from low-income backgrounds. The lack of effective recruitment may be due, in part, to the level of cultural competency inherent in the design, content, and implementation of existing parenting classes. Using semi-structured interviews and the qualitative methodology of grounded theory, this study explored the self-reported parenting beliefs, values, and struggles of a sample of low-income African American mothers whose children are at high risk for juvenile delinquency, youth violence, and child maltreatment and explicated a theory that connects such beliefs to parenting skills classes. These data may be useful in guiding parenting program design to increase the relevancy and effectiveness of parenting skills classes for this population.

description: A novel 1:1 supramolecular dye inclusion complex between inverted cucurbit[7]uril (iQ[7]) and Thioflavin T (THT) has been successfully constructed on the basis of host–guest recognition. The obtained results revealed that THT exhibited obvious iQ[7]-induced fluorescence enhancement in this inclusion complex system, and the N-dimethyl and benzene ring moiety of the guest THT were located inside the cavity of iQ[7], whereas the other section of THT remained outside the portal. And THT@iQ[7] was highly stimuli-responsive to competing guests. These results provided a possibility for application in the molecular recognition area.
Performance evaluation of network-on-chip interconnect architectures
Creators: name: Zhou, Xinan
Publisher: name: University of Nevada, Las Vegas

description: With a communication design style, Network-on-Chips (NoCs) have been proposed as a new Multi-Processor System-on-Chip paradigm. Simulation and functional validation are essential to assess the correctness and performance of the NoC design. In this thesis, a cycle-accurate NoC simulation system in Verilog HDL is developed to evaluate the performance of various NoC architectures. First, a library of NoC components is developed based on an existing design. Each NoC architecture to be evaluated is constructed from the library according to the topology description which specifies the network topology, network size, and routing algorithm. The network performance of four NoC architectures under uniform and three non-uniform traffic patterns is tested on ModelSim 6.4. The developed NoC simulation system provides useful resources for the future development of the FPGA-based NoC emulation system.

description: A novel approach to account for hard-body interactions in (overdamped) Brownian dynamics simulations is proposed for systems with non-vanishing force fields. The scheme exploits the analytically known transition probability for a Brownian particle on a one-dimensional half-line. The motion of a Brownian particle is decomposed into a component that is affected by hard-body interactions and into components that are unaffected. The hard-body interactions are incorporated by replacing the affected component of motion by the evolution on a half-line. It is discussed under which circumstances this approach is justified. In particular, the algorithm is developed and formulated for systems with space-fixed obstacles and for systems comprising spherical particles. The validity and justification of the algorithm is investigated numerically by looking at exemplary model systems of soft matter, namely at colloids in flow fields and at protein interactions. Furthermore, a thorough discussion of properties of other heuristic algorithms is carried out.

description: Diversity initiatives have evolved from a focus on compliance-oriented training to a systematic approach which integrates the many dimensions of diversity in all aspects of business to enhance performance through the practice of organization development (OD) (Bendick, Egan, & Lofhjelm, 2001). Many organizations have implemented short term solutions to address the demographic changes in the workforce, but have had minimal results. When diversity interventions are conceptually grounded in organization development practices the results are much more substantial for both the employees and the organization (2001).

The purpose of this qualitative case study was to explore the perceived influential factors of effective organizational change for instituting diversity initiatives and to investigate the process of implementing diversity initiatives successfully in one hospitality organization. Key findings indicate that OHI utilized the following concepts and strategies while instituting change relating to their diversity efforts: Leadership Commitment, Corporate Values, Education, Communication, Accountability, and Organizational Infrastructure. The findings from this study can assist in highlighting key strategies for implementing diversity interventions that are perceived to be successful for improving future diversity initiatives. It can assist organization development (OD) consultants; workplace learning and performance (WLP) practitioners and human resource (HR) managers develop a better understanding using a systems approach for addressing diversity.
Passive Learning with Target Risk

description: In this paper we consider learning in passive setting but with a slight modification. We assume that the target expected loss, also referred to as target risk, is provided in advance for learner as prior knowledge. Unlike most studies in the learning theory that only incorporate the prior knowledge into the generalization bounds, we are able to explicitly utilize the target risk in the learning process. Our analysis reveals a surprising result on the sample complexity of learning: by exploiting the target risk in the learning algorithm, we show that when the loss function is both strongly convex and smooth, the sample complexity reduces to $Ø(\log (\frac{1}ε))$, an exponential improvement compared to the sample complexity $Ø(\frac{1}ε)$ for learning with strongly convex loss functions. Furthermore, our proof is constructive and is based on a computationally efficient stochastic optimization algorithm for such settings which demonstrate that the proposed algorithm is practically useful.

description: Статья посвящена истории отношений М.Горького с одним из сотрудников издательства «Всемирная литература», приват-доцентом Петербургского университета, германистом и специалистом по скандинавским литературам Б.П.Сильверсваном, который входил в Редакционную коллегию экспертов издательства по отделу скандинавских литератур. Известность Сильверсван получил после публикации его письма к А.В.Амфитеатрову 1931 года, ставшим ключевым свидетельством в вопросе о причастности Н.С.Гумилева к Таганцевскому заговору. В данной публикации используется другая часть этого письма Сильверсвана, где он рассказывает о содержании своего разговора с Горьким, состоявшегося осенью 1921 года, накануне бегства Сильверсвана из России вместе с Евдокией Петровной Струковой, секретарем издательства «Всемирная литература» и хорошей знакомой Горького. В этом разговоре Горький не только поддержал их намерение эмигрировать, но и сделал целый ряд признаний, касающихся его отношения к большевистским властям и В.И.Ленину. Письма Сильверсвана Горькому публикуются впервые по автографам из Архива А.М.Горького Института мировой литературы им. А.М.Горького Российской академии наук. Они свидетельствуют о том, что писатель продолжал поддерживать отношения с Сильверсваном в период эмиграции и откликался по мере возможностей на его просьбы и ходатайства.

description: River Ganga, one of the largest perennial rivers, conserves the cultural heritage of the Indian sub-continent, supporting as the nectar of life to millions residing on the banks of the river basin. With unlimited use, the river also receives a large amount of untreated wastewater discharged from different industrial, commercial and residential complexes, unbalancing the nutrient concentration at many points along the stretch. The current study assesses water samples collected from 20 monitoring locations and the Ganga River System in the Himalayan region, evaluating the potential risk of heavy metal pollution. The concentration of Zn, Pb, Mn, Fe, Cu, Al, Ni, Cd, Mg and Co is determined by atomic absorption spectrophotometer (AAS). Fe, Cd and Mg’s observed values exceeded various standards (WHO, BIS and USEPA) for drinking water. The pollution assessment index (heavy metal pollution index: HPI) and multivariate analysis (principal component analysis: PCA and cluster analysis: CA) were implemented to identify the intensity of pollution and its sources. The seasonal values of HPI were found 88.69, 90.32, 88.53 and 84.96 in winter, summer, monsoon and post-monsoon seasons. The index value on all monitoring locations varied between the range of PCA outcomes for three factors and explained 72.1% of the variance, indicating natural and man-made activities as responsible metal abundance factors in the river system. The hazard quotient (HQ) and hazard index (HI) are used to assess non-cancer health risks to humans. The seasonal evaluation recorded HQ < 1 for all the metals and HI > 1 was found for the entire study period. This study contributes to various conservation initiatives for the River Ganga System with factual datasets and characterization of various sampling locations using heavy metal indexing while sharing common masses’ findings for people participation at the regional level.

description: Geoscience field trip guidebooks are indexed by GeoRef/AGI and are an important source of local geologic information that is often not found elsewhere. More and more field trip guides are found online for a short duration, in and around the time the trip was hosted. In the past, field trip guides were published or offered in print and many libraries tried to collect, or purchase them as they became available. As many field trip guides are now solely available online, purchasing print copies is not always possible. Many online guidebooks are not archived elsewhere and once the conference or trip is over, are left to languish and are often at risk for being lost as people leave the institution that hosted the trip. The Geologic Field Trip Guidebooks Web Archive seeks to create a web archive that will preserve online geologic field trip guidebooks that are not archived online elsewhere. This online collection would be free and available for researchers and scholars to use, and would be made available through the Internet Archive (https://archive.org/). The first phase will be to archive the online guidebooks cataloged in the Geologic Guidebooks of North America Database (GGNAD) that are not already preserved elsewhere. The web archive would be a full text archive that would complement the GGNAD. This project is currently in development and has been funded through the Ivy Plus Web Collecting Program.
