Purpose Society may be on the verge of a revolutionary phase of mobile device use in higher education generally and in libraries in particular. This paper seeks to address this issue. Design/methodology/approach Through an examination of trends and technological developments in the area of mobile devices and a review of the potential of mobile devices, the paper analyzes the potential of mobile devices in academic libraries. Findings Most college students own cell phones and laptops and the capabilities of these and other devices are expanding. Research limitations/implications Libraries have the opportunity to extend new types of services to users of mobile devices and to develop, license, or otherwise make available scholarly content that is configured for mobile devices. Ideally, libraries will become part of an institutional planning process for the development of services for mobile devices. Practical implications The more pervasive use by students of smartphones, the uptake of e‐book readers, and the increasing use of mobile devices in some areas of the curriculum all have implications for libraries. Social implications Some writers in this area believe that the increased capabilities of mobile devices could lead to new forms of engagement with student learning; this possibility can be embraced by academic libraries that seek to be strong partners in the teaching and learning process of their institution. Originality/value The paper synthesizes developments and provides suggestions for the future.

ABSTRACT Information Commons are popular with millennial (also called net generation) students, who often work in groups, use technology avidly, and combine their academic and social lives. Enhancing the configuration of services for the Information Commons can assist in leveraging the value of the available content, hardware, software, and physical setting to support learning and academic programs. Understanding millennial students’ lifestyle is key to developing a robust service program to engage and support them.

Although many libraries already offer some type of reference service geared toward people who use mobile devices, they generally focus on the reference transaction and not on some of the broader aspects of service, including availability of content for mobile devices and relationship of the library's services to mobile initiatives on campus. Asking the right questions during the planning process can assist librarians in clarifying their goals for the service, identifying units to work with on campus, and determining whether the service is successful. This is a rapidly developing area and flexibility is key.

The lower critical solution temperature (LCST) of poly-N-isopropylacrylamide (p-NIPAM) diminishes when a small volume of acetone is added to the aqueous polymer solution, and then increases for further additions, producing a minimum at a certain acetone concentration. Here this behavior is observed through the variation of the hydrodynamic radius RH of p-NIPAM microgels with temperature, measured by dynamic light scattering (DLS), when adding increasing amounts of acetone in the molar fraction range of 0.00 to 0.25. This size trend of microgels with temperature is well captured by all-atom molecular dynamic simulations, which are implemented for a single 30-mer, at similar solvent and temperature conditions. Both DLS measurements and simulations indicate that the shrunken state continuously augments its size with increasing acetone content. This, in turn, leads to a minimum of the globule-to-coil transition temperature, which should correspond to the minimum of the LCST. Furthermore, density profiles, as obtained by considering a membrane arrangement of oligomers, reveal a preferential interaction of the polymer with acetone to the detriment of water. We observe how the membrane loses water content as the temperature is increased while keeping a similar amount of acetone in its interior. This competition between water and acetone for the polymer surface plays a major role in the enthalpy driven dependence of the critical temperature with acetone concentration.

Outlines the traditional issues surrounding authentication and authorization before charting the changing nature of the requirements for these services, as a fully networked information environment becomes a reality. Highlights some of the technical, organizational and policy issues which need to be addressed to create appropriate standards and infrastructure.

The panel will discuss various aspects of the ongoing Object Re-Use and Exchange (ORE) effort of the Open Archives Initiative (OAI). OAI-ORE is funded by the Andrew W. Mellon Foundation and is a result of the "Augmenting Interoperability across Scholarly Repositories" meeting that took place in April 2006 at the Mellon Foundation. A panel at JCDL 2006 reported on this meeting. The goal of OAI-ORE is to develop, identify, and profile extensible standards and protocols that allow repositories, agents, and services to interoperate in the context of use and reuse of compound digital objects beyond the boundaries of the holding repositories.

O presente trabalho tem por objetivo apresentar e avaliar a evolucao das politicas publicas de promocao e apoio as Pequenas e Medias Empresas (PMEs) no Brasil. A intencao e indicar as principais alteracoes ocorridas no marco institucional e na agenda de politicas publicas para PMEs desde os anos 1960, bem como seus impactos para as PMEs brasileiras, sempre considerado a compreensao do quadro macroeconomico e a conformacao da politica industrial e tecnologica em cada momento. O intuito mais especifico do estudo e assinalar a trajetoria recente de mudancas no aparato institucional, nas politicas e nos instrumentos de apoio as PMEs, e destacar o redirecionamento das acoes para grupos de PMEs e para a articulacao das empresas. No processo recente de reestruturacao produtiva mundial, conforme ha varios trabalhos empiricos produzidos nos ultimos anos, observa-se a formacao de diversos tipos de articulacao de empresas, por vezes em decorrencia da externalizacao de atividades de grandes empresas, e o reforco da insercao de PMEs em aglomeracoes produtivas. Essas configuracoes de estrutura produtiva que unem empresas em torno a um determinado espaco geografico e propiciam novos modos de insercao competitiva para pequenas e medias empresas acabaram sendo genericamente identificadas pelo termo Arranjo Produtivo Local (APL).

The surface structure of Few-Layer Graphene (FLG) epitaxially grown on the C-face of SiC has been investigated by TM-AFM in ambient air and upon interaction with dilute aqueous solutions of bio-organic molecules (l-methionine and dimethyl sulfoxide, DMSO). Before interaction with molecular solutions, we observe nicely ordered, three-fold oriented rippled domains, with a 4.7 ± 0.2 nm periodicity (small periodicity, SP) and a peak-to-valley distance in the range 0.1-0.2 nm. Upon mild interaction with the molecular solution, the ripple periodicity "relaxes" to 6.2 ± 0.2 nm (large periodicity, LP), while the peak-to-valley height increases to 0.2-0.3 nm. When additional energy is transferred to the system through sonication in solution, graphene planes are peeled off, as shown by quantitative analysis of Raman spectroscopy and X-ray photoelectron spectroscopy which indicate a neat reduction of thickness. Upon exfoliation rippled domains are no longer observed. In comparative experiments on cleaved HOPG, we could not observe ripples on pristine samples in ambient air, while LP ripples develop upon interaction with the molecular solutions. Recent literature on similar systems is not univocal regarding the interpretation of rippling. The ensemble of our comparative observations on FLG and HOPG can be hardly rationalized solely on the basis of the surface assembly of molecules, either organic molecules coming from the solution or adventitious species. We propose to consider rippling as the manifestation of the free-energy minimization of quasi-2D layers, eventually affected by factors such as interplanar stacking, and interactions with molecules and/or with the AFM tip.

This presentation will take a very broad view of the emergence of literary corpora as objects of computation, with a particular focus on the various literatures and genres that form the scholarly record. The developments and implications here that I will explore include: the evolution of the scholarly literature into a semi-structured network of information used by both human readers and computational agents through the introduction of markup technologies; the interpenetration and interweaving of data and evidence with the literature; and the creation of an invisible infrastructure of names, taxonomies and ontologies, and the challenges this presents.

Abstract This paper shows how a shorter fecundity horizon for females (a biological constraint) leads to age and educational disparities between husbands and wives. Empirical support is based on data from a natural experiment commencing before and ending after China’s 1980 one-child law. The results indicate that fertility in China declined by about 1.2–1.4 births per woman as a result of China’s anti-natalist policies. Concomitantly spousal age and educational differences narrowed by approximately 0.5–1.0 and 1.0–1.6 years, respectively. These decreases in the typical husband’s age and educational advantages are important in explaining the division of labor in the home, often given as a cause for the gender wage gap. Indeed, as fertility declined, which has been the historical trend in most developed countries, husband-wife age and educational differences diminished leading to less division of labor in the home and a smaller gender wage disparity. Unlike other models of division of labor in the home which rely on innately endogenous factors, this paper’s theory is based on an exogenous biological constraint.

Purpose The purpose of this paper is to look back on the last 30 years of technology development for libraries. Design/methodology/approach The paper presents an interview that took place at the American Library Association Annual Meeting in Anaheim, California. Findings The paper reveals that many of the developments are slow. There are very few really sudden revolutions in social‐scale technologies. They do not switch on quickly and cannot be sudden because the installed base is too thin. Originality/value The paper reveals that there should be some renewed conversation about how libraries can help the public. In the early days of the internet libraries played an enormous uncredited role in teaching the adult population about the internet. There are some opportunities like that now, and one place where we are starting to see signs of it is digital preservation, not as libraries doing it for the cultural record, but helping individuals to do it for their own content.

Cases of pulmonary embolism and pulmonary artery hypertension caused by choriocarcinoma represent a rare clinical emergency. We report a case of a 25-year-old woman who presented with pulmonary embolism and hypertension and died soon after complete pulmonary embolectomy. A related literature review revealed that almost all of these patients had previously experienced a spontaneous abortion (average, 6 months) and were not pregnant.

Automatic speech recognition (ASR) plays a vital role in human-machine interaction across a variety of applications, including conversational agents, industrial robotics, call center automation, and automated subtitling. However, building high-performing ASR models remains challenging, especially for low-resource languages like Arabic, due to the limited availability of large, labeled speech datasets, which are expensive and time-consuming to create. In this work, we utilize weakly supervised learning to train an Arabic ASR model based on the Conformer architecture. Our model is trained from scratch on 15,000 hours of weakly annotated speech data, encompassing both Modern Standard Arabic (MSA) and Dialectal Arabic (DA), thereby removing the dependency on costly manual transcriptions. Despite lacking human-verified labels, our method achieves state-of-the-art (SOTA) performance in Arabic ASR, outperforming both open and closed-source models on standard benchmarks. This demonstrates the potential of weak supervision as a scalable and cost-effective alternative to traditional supervised learning, paving the way for enhanced ASR systems in low-resource environments.

The employment of 2D materials, as growth substrates or buffer layers, enables the epitaxial growth of layered materials with different crystalline symmetries with a preferential crystalline orientation and the synthesis of heterostructures with a large lattice constant mismatch.

In 2006 the American Council of Learned Societies (ACLS) released Our Cultural Commonwealth, the final report of the Commission on Cyberinfrastructure for the Humanities and Social Sciences. The report, based on a study funded by the Mellon Foundation, explored how research environments might be created for the humanities and social sciences to complement those being developed to support scientific research. The report includes key recommendations addressed to universities, funding agencies, scholarly societies, academic libraries, publishers, Congress, state legislatures, and others. Implementation of the recommendations could potentially transform scholarship and exponentially increase access to resources and new scholarship in the humanities and social sciences. But the report has not been universally embraced. How will humanities scholarship be advanced by new technologies and research practices, and how will the academic community recognize new forms of scholarship? How will funding agencies respond to the challenges and issues raised? What does cyberinfrastructure mean for different domains within the humanities? These questions will be addressed by panelists and discussed by participants.

The 96 genotypes of Trigonella foenum-graecum L. (Fenugreek) were estimated by using Sodium Dodecyl Sulphate Poly Acrylamide Gel Electrophoresis (SDS-PAGE). The accessions were maintained from diverse ecological areas of the world. Total seed storage proteins were electrophoresis on 12.5% polyacrylamide gels. A total of 17 protein bands were detected, of which seven were highly polymorphic and six were moderate polymorphic and four were low polymorphic with molecular weight extending from of ~15 to ~180 kDa. The dendrogram based on similarity matrix using Unweighted Pair Group Method with Arithmetic Mean (UPGMA) divided all the genotypes into four major clusters i.e., I, II, III and IV comprising 51, 24, 10 and 11 accessions, respectively. Although limited genetic diversity was detected amongst known germplasm but the presence/absence of polymorphic bands revealed a significant variances among different Trigonella genotypes. The differences exposed in this project work should be oppressed for the future breeding prospective of Trigonella genotypes by using other advanced molecular techniques. The SDS-PAGE per se seems inadequate tool for such kind of analysis, and may be integrated with other genetic and sequence based approaches for more precise estimation of the genetic variability within closely related accessions. Our results provide baseline for obtaining locally adapted and improved cultivars of fenugreek in Pakistan.
