Ebooks vs. print books: Readers' choices and preferences across contexts
Authors: Zhang Yin , Kudva Sonali 
Published: May 2014

AbstractWith electronic book (ebook) sales and readership rising, are ebooks positioned to replace print books? This study examines the preference for ebooks and print books in the contexts of reading purpose, reading situation, and contextual variables such as age, gender, education level, race/ethnicity, income, community type, and Internet use. Additionally, this study aims to identify factors that contribute to ebook adoption. The results of this study support the notion that ebooks have firmly established a place in people's lives, but are not yet positioned to take over all the roles of print books. Both print books and ebooks have unique attributes and serve irreplaceable functions in meeting people's reading needs, which may vary by individual demographic, contextual, and situational factors.
Agricultural information and empire building in the late 19th century: National information policy, the people, and the USDA
Authors: D'Arpa Christine 
Published: May 2014

AbstractThe information work of the United States Department of Agriculture in its first years as an independent federal agency—1862 to 1888—was exceptional and contested. It engaged the public to collect information relevant to farming, markets, and trade. Through a close historical analysis of the Department's annual reports and supplementary materials, I examine that information work and situate it within the context of the emergence of the modern state, American empire, and industrializing capitalism using Marxist historiography and the political economy of information as my conceptual framework.

Authors: Yan Jasy Liew Suet , Hassman Katie DeVries , Zhang Ping 
Published: May 2014

AbstractThe interdisciplinary nature of the information field (iField) calls for a greater understanding of how iSchool scholars engage with information technology in their research. The purpose of this article is to study how much emphasis iSchool scholars put into studying technology, and how they conceptualize technology in their research. Using content analysis as our method of investigation, we coded journal articles published by tenure track faculty members between 2008 and 2010 from five iSchools (Drexel, Michigan, Pittsburgh, Syracuse, and Washington). We report preliminary empirical evidence showing a microscopic view on the diversity in how iSchool scholars engage with technology, one of the fundamental components in the iField.
Automatically infer subject terms and documents associations through text mining
Authors: Lu Kun , Mao Jin 
Published: May 2014

AbstractSubject indexing is an intellectual intensive process that bears many inherent uncertainties. Existing subject index systems generally produce binary outcomes on whether assigning an indexing term or not, which does not sufficiently reflect to which extent the indexing terms are associated with documents. On the other hand, probabilistic models have seen great success in capturing the uncertainties in the automatic indexing process. One hurdle to achieving weighted indexing in manual subject indexing process is the practical burden that could be added to the already intensive indexing process. In this study, we propose a method to automatically infer the associations between subject terms and documents through text mining. By uncovering the connections between MeSH terms and document text, we are able to derive the weights of MeSH terms in documents. Our initial results suggest that the new method is feasible and promising. The study has practical implications for improving subject indexing practice.
Citation functions in social sciences and humanities: Preliminary results from a citation context analysis of Taiwan's history research journals
Authors: Lin Chi‐Shiou , Chen Yi‐Fan , Chang Chieh‐Yu 
Published: May 2014

AbstractThis ongoing study employs citation context analysis to examine the citation functions in social sciences and humanities (SS&H) disciplines. The analyses focus on the uses of organic/perfunctory citations and confirmative/negational citations. In this poster, we will present the preliminary findings from the completed analysis on Chinese history research papers. Chinese history authors used a large amount of perfunctory citations. The percentage of negational citations was also high, and many papers have negated a previous research. It has seriously challenged the citation analysis assumptions that citations are of equal contribution and that citation means author endorsement of previous literatures. We will continue to complete the analyses for the other chosen SS&H disciplines, and we encourage other researchers to extend the analysis to other subject areas and in other countries or languages so as to better understand researchers' citation behavior and to better assess the applicability of citation analysis in different domains.
Comparing the use of semantic relations between tags versus latent semantic analysis for generic speech summarization
Authors: Kim Hyun Hee 
Published: May 2014

AbstractWe proposed an advanced tag method in which original tags are expanded and the semantic relations between original or expanded tags are used to extract key sentences from lecture speech transcripts. Then, to evaluate our proposed method, we compared it with two other methods, a tag method of using only original tags and a latent semantic analysis (LSA) method. As a result, the F measure mean (0.31) of the advanced tag method is higher than that (0.29) of LSA method and it is also higher than that (0.27) of the tag method, although there is no significant difference between them respectively.

The survey assesses the value of the program to graduates, career placement, and continuing education needs. Preliminary findings and trends are reported to inform the evolution of data curation education in library and information science (LIS) programs.
Information needs of adults living with type 2 diabetes: When cookbooks are more than just recipes
Authors: Whetstone Melinda 
Published: May 2014

AbstractAdults managing life with Type 2 diabetes may receive material about diabetes and management, or they may seek health information. They may also keep information items in the home for subsequent use. Currently, health technology is striving to push topically relevant information items, but successful technology would deliver unique, but relevant information. Thus, a holistic view of kept information items, item uses, and information needs are required. Research of information needs, seeking, and use (INSU) often views information needs as explicit statements, but latent information needs may also exist. Kept and used information items may serve to project these implicit information needs. This exploratory study aimed to identify both explicit and implicit information needs of adults living with Type 2 diabetes. Semi‐structured interviews conducted in 21 participant's homes focused on kept and used items (n = 300). Resulting rich narratives provided insight of context, item acquisition, and item usage. The results indicate that the majority of items kept and used to manage life with diabetes are paper based and pertain to nutritional management. However, items and their abundance also projected information needs. These findings and their implications contribute to discussions of diabetes‐related collections development and health information technology tools.
The impact of operational decisions on the design of salesforce incentives
Authors: Saghafian Soroush , Chao Xiuli 
Published: May 2014

AbstractWhen facing high levels of overstock inventories, firms often push their salesforce to work harder than usual to attract more demand, and one way to achieve that is to offer attractive incentives. However, most research on the optimal design of salesforce incentives ignores this dependency and assumes that operational decisions of production/inventory management are separable from design of salesforce incentives. We investigate this dependency in the problem of joint salesforce incentive design and inventory/production control. We develop a dynamic Principal‐Agent model with both Moral Hazard and Adverse Selection in which the principal is strategic and risk‐neutral but the agent is myopic and risk‐averse. We find the optimal joint incentive design and inventory control strategy, and demonstrate the impact of operational decisions on the design of a compensation package. The optimal strategy is characterized by a menu of inventory‐dependent salesforce compensation contracts. We show that the optimal compensation package depends highly on the operational decisions; when inventory levels are high, (a) the firm offers a more attractive contract and (b) the contract is effective in inducing the salesforce to work harder than usual. In contrast, when inventory levels are low, the firm can offer a less attractive compensation package, but still expect the salesforce to work hard enough. In addition, we show that although the inventory/production management and the design of salesforce compensation package are highly correlated, information acquisition through contract design allows the firm to implement traditional inventory control policies: a market‐based state‐dependent policy (with a constant base‐stock level when the inventory is low) that makes use of the extracted market condition from the agent is optimal. This work appears to be the first article on operations that addresses the important interplay between inventory/production control and salesforce compensation decisions in a dynamic setting. Our findings shed light on the effective integration of these two significant aspects for the successful operation of a firm. © 2014 Wiley Periodicals, Inc. Naval Research Logistics 61: 320–340, 2014
MicroRNA‐101 suppresses liver fibrosis by targeting the TGFβ signalling pathway

Published: May 2014

AbstractTransforming growth factor‐β (TGFβ) is crucial for liver fibrogenesis and the blunting of TGFβ signalling in hepatic stellate cells (HSCs) or hepatocytes can effectively inhibit liver fibrosis. microRNAs (miRNAs) have emerged as key regulators in modulating TGFβ signalling and liver fibrogenesis. However, the regulation of TGFβ receptor I (TβRI) production by miRNA remains poorly understood. Here we demonstrate that the miR‐101 family members act as suppressors of TGFβ signalling by targeting TβRI and its transcriptional activator Kruppel‐like factor 6 (KLF6) during liver fibrogenesis. Using a mouse model of carbon tetrachloride (CCl4)‐induced liver fibrosis, we conducted a time‐course experiment and observed significant down‐regulation of miR‐101 in the fibrotic liver as well as in the activated HSCs and injured hepatocytes in the process of liver fibrosis. Meanwhile, up‐regulation of TβRI/KLF6 was observed in the fibrotic liver. Subsequent investigations validated that TβRI and KLF6 were direct targets of miR‐101. Lentivirus‐mediated ectopic expression of miR‐101 in liver greatly reduced CCl4‐induced liver fibrosis, whereas intravenous administration of antisense miR‐101 oligonucleotides aggravated hepatic fibrogenesis. Mechanistic studies revealed that miR‐101 inhibited profibrogenic TGFβ signalling by suppressing TβRI expression in both HSCs and hepatocytes. Additionally, miR‐101 promoted the reversal of activated HSCs to a quiescent state, as indicated by suppression of proliferation and migration, loss of activation markers and gain of quiescent HSC‐specific markers. In hepatocytes, miR‐101 attenuated profibrogenic TGFβ signalling and suppressed the consequent up‐regulation of profibrogenic cytokines, as well as TGFβ‐induced hepatocyte apoptosis and the inhibition of cell proliferation. The pleiotropic roles of miR‐101 in hepatic fibrogenesis suggest that it could be a potential therapeutic target for liver fibrosis.

Abstract
The role of erythropoietin (Epo) in myocardial repair after infarction remains inconclusive. We observed high Epo receptor (EPOR) expression in cardiac progenitor cells (CPCs). Therefore, we aimed to characterize these cells and elucidate their contribution to myocardial regeneration on Epo stimulation. High EPOR expression was detected during murine embryonic heart development followed by a marked decrease until adulthood. EPOR-positive cells in the adult heart were identified in a CPC-enriched cell population and showed coexpression of stem, mesenchymal, endothelial, and cardiomyogenic cell markers. We focused on the population coexpressing early (TBX5, NKX2.5) and definitive (myosin heavy chain [MHC], cardiac Troponin T [cTNT]) cardiomyocyte markers. Epo increased their proliferation and thus were designated as Epo-responsive MHC expressing cells (EMCs). In vitro, EMCs proliferated and partially differentiated toward cardiomyocyte-like cells. Repetitive Epo administration in mice with myocardial infarction (cumulative dose 4 IU/g) resulted in an increase in cardiac EMCs and cTNT-positive cells in the infarcted area. This was further accompanied by a significant preservation of cardiac function when compared with control mice. Our study characterized an EPO-responsive MHC-expressing cell population in the adult heart. Repetitive, moderate-dose Epo treatment enhanced the proliferation of EMCs resulting in preservation of post-ischemic cardiac function. Stem Cells 2014;32:2480–2491

Abstract
Adult neurogenesis is a multistep process regulated by several extrinsic factors, including neurotrophins. Among them, little is known about the role of nerve growth factor (NGF) in the neurogenic niches of the mouse. Here we analyzed the biology of adult neural stem cells (NSCs) from the subventricular zone (SVZ) of AD11 anti-NGF transgenic mice, in which the expression of the recombinant antibody aD11 leads to a chronic postnatal neutralization of endogenous NGF. We showed that AD11-NSCs proliferate 10-fold less, with respect to their control counterparts, and display a significant impairment in their ability to differentiate into β-tubulin positive neurons. We found a considerable reduction in the number of SVZ progenitors and neuroblasts also in vivo, which correlates with a lower number of newborn neurons in the olfactory bulbs of AD11 mice and a severe deficit in the ability of these mice to discriminate between different odors. We also demonstrated that, in AD11 mice, the morphology of both SVZ-resident and neurosphere-derived astrocytes is significantly altered. We were able to reproduce the AD11 phenotype in vitro, by acutely treating wild type NSCs with the anti-NGF antibody, further demonstrating that both the proliferation and the differentiation defects are due to the NGF deprivation. Consistently, the proliferative impairment of AD11 progenitors, as well as the atrophic morphology of AD11 astrocytes, can be partly rescued in vitro and in vivo by exogenous NGF addition. Altogether, our results demonstrate a causal link between NGF signaling and proper proliferation and differentiation of neural stem cells from the SVZ. Stem Cells 2014;32:2516–2528
Evaluation of models for estimating concrete strains due to drying shrinkage
Authors: Theiner Yvonne , Andreatta Andreas , Hofstetter Günter 
Published: May 2014

AbstractThe present contribution focuses on a comparative study of shrinkage prediction models according to the European Standard Eurocode 2 (EC2), the recommendation by ACI committee 209 and fib Model Code for Concrete Structures 2010. The estimated ultimate drying shrinkage strains and the predicted evolution of drying shrinkage strains are compared with respective shrinkage strains measured on normal‐strength concrete specimens of different sizes. For all prediction models, the estimated ultimate values are found to agree quite well with the ultimate drying shrinkage strains measured on thin concrete slices. Whereas the evolution of drying shrinkage strains measured on small concrete prisms agree quite well with the predicted values, substantial differences between code values and experimental data are encountered for larger specimen sizes.
Challenges for concrete in tall buildings
Authors: Clark Gordon 
Published: May 2014

AbstractTall buildings present unique challenges in terms of both design and construction. The definition of tall is always a matter for debate and actually is related to the proportions of the building, although the actual physical height does also result in other influences such as extreme lateral loading.Concrete features prominently in providing the structural material for most cores and framing options, thus ensuring stability of the structure. The core of a tall building is important structurally as well as for forming the spine for vertical transportation and services. There can be a wide choice of size and shape, which is dictated in part by the geometry of the building and the site.This paper focuses on some of the issues for concrete, which is a key material in tall building construction, and is based on some of the work of an fib task group that has been formed to bring together important guidance based on experience of design and construction.
Aspects of imposed deformation in concrete structures – a condensed overview
Authors: Reinhardt Hans‐Wolf 
Published: May 2014

AbstractImposed deformation is a special case of loading that gets much less attention than mechanical loading due to external forces. However, imposed deformation can impair the serviceability of structures such as tightness and durability. Imposed deformations are due to shrinkage of concrete and temperature variations. The boundary conditions play an important role when analysing stresses due to imposed deformation. This paper provides an overview.

Who Gets Custody Now? Dramatic Changes in Children’s Living Arrangements After Divorce

Published: May 2014

Abstract
This article reexamines the living arrangements of children following their parents’ divorce, using Wisconsin Court Records, updating an analysis that showed relatively small but significant increases in shared custody in the late 1980s and early 1990s. These changes have accelerated markedly in the intervening years: between 1988 and 2008, the proportion of mothers granted sole physical custody fell substantially, the proportion of parents sharing custody increased dramatically, and father–sole custody remained relatively stable. We explore changes in the correlates of alternative custody outcomes, showing that some results from the earlier analysis still hold (for example, cases with higher total family income are more likely to have shared custody), but other differences have lessened (shared-custody cases have become less distinctive as they have become more common). Despite the considerable changes in marriage and divorce patterns over this period, we do not find strong evidence that the changes in custody are related to changes in the characteristics of families experiencing a divorce; rather, changes in custody may be the result of changes in social norms and the process by which custody is determined.
Mother–adolescent monitoring dynamics and the legitimacy of parental authority
Authors: Keijsers Loes , Laird Robert D. 
Published: May 2014

ABSTRACTThis multi‐informant longitudinal study aimed to understand whether the family dynamics that underlie adolescent voluntary disclosure regarding their leisure time behavior differs when adolescents strongly or weakly endorse the legitimacy of parental authority. Longitudinal linkages between parental monitoring behaviors and adolescents' secrecy and disclosure were tested among youths with strong and weak legitimacy beliefs. The sample included 197 adolescents (51% female, M age 12 years) and their mothers. Mothers reported on several of their own monitoring efforts (i.e., solicitation, active involvement, observing and listening, and obtaining information from spouses, siblings, and others). Adolescents reported their disclosure, secrecy, and legitimacy beliefs. Only among youths reporting strong legitimacy beliefs, more mother engagement and supervision (indexed by mother‐reported active involvement and observing and listening) predicted more adolescent disclosure and less secrecy over time, and more mother solicitation predicted less secrecy.
