RDAP12 summit: Challenges and opportunities for data management
Authors: Wickett Karen M. , Hu Xiao , Thomer Andrea 
Published: June 2012

AbstractEditor's SummaryLibrarians, data managers and educators convened at ASIS&T's third annual Research Data Access and Preservation Summit in March 2012 to discuss the complex issues involved in managing research data. Major topics included the sociocultural landscape of data management, education and training for data managers, and data citation practices. Among the many questions without answers were the issues of revenue sources and whether science data curation services are better handled by institutions or scientific communities. Financial and technical sustainability are critical, together with human sustainability, including data managers' training and education. While the relative importance of data management theory and technical skills was a matter of debate, all supported the need for continuing education in data curation. There was agreement that current data citation practices are inconsistent and that citation metadata standards and unique and persistent identifiers for datasets are necessary.
Data citation initiatives and issues
Authors: Mayernik Matthew S. 
Published: June 2012

AbstractEditor's SummaryThe importance of formally citing scientific research data has been recognized for decades but is only recently gaining momentum. Several federal government agencies urge data citation by researchers, DataCite and its digital object identifier registration services promote the practice of citing data, international citation guidelines are in development and a panel at the 2012 ASIS&T Research Data Access and Preservation Summit focused on data citation. Despite strong reasons to support data citation, the lack of individual user incentives and a pervasive cultural inertia in research communities slow progress toward broad acceptance. But the growing demand for data transparency and linked data along with pressure from a variety of stakeholders combine to fuel effective data citation. Efforts promoting data citation must come from recognized institutions, appreciate the special characteristics of data sets and initially emphasize simplicity and manageability.
The changed and changing ADI/ASIS/ASIS&T after 75 years
Authors: Williams Robert V. 
Published: June 2012

AbstractEditor's SummaryA review of the history and growth of ASIS&T since its origin as the American Documentation Institute (ADI) reflects the development of the concept of information science. Spearheaded by Watson Davis in 1937, the ADI focused on micro‐photographic techniques and bibliography and on documentation principles and practices. Despite a shaky start and meager funding, the ADI adapted to new technologies, terminology and subject analysis methods, and started the journal American Documentation in 1950. Growth in science research in the '50s and '60s sparked an explosion of technical reports, prompting coordination with the Special Libraries Association and other groups and leading to a demand for more specialized professional skills, which was met in the '60s and '70s by expansion and focus on education in information science. The membership shifted to a majority in academia and shrinking minority in industry, and debate continued over the geographic scope and name of the organization, which added “and Technology” to its name in 2000. American Documentation transitioned in stages into the Journal of the American Society for Information and Technology, while the Bulletin and Annual Review were added, and annual conferences provided another educational resource. The publications became the basis of an arrangement with the publisher Wiley that would stabilize finances. Over 75 years, from ADI to ASIS to ASIS&T, the organization has met the evolving needs of the information science and technology community.
The cost‐effectiveness of the dangerous and severe personality disorder programme
Authors: Barrett Barbara , Tyrer Peter 
Published: June 2012

ABSTRACTBackgroundMuch resource (c £500M) has been spent in setting up the programme of treatment for those deemed to be suffering from dangerous and severe personality disorder (DSPD). It has now begun to contract, and it is an appropriate time to evaluate its cost‐effectiveness.AimsThe aim of the study was to review all published and known unpublished material, examining the cost, cost function and cost‐effectiveness of the DSPD programme since its introduction in 1999.MethodsNarrative review of studies was used.ResultsFour studies, one unpublished, were identified. The costs of treating people in the DSPD programme are considerably higher than those in other parts of the prison service. This could be justified if the gains justified this increased investment, but the evidence suggests that the outcomes in the short term are not good, and the monetary value of reductions in serious offences is very small compared with the extent of the higher costs incurred. There is a dearth of randomised trials that would allow an adequate assessment of cost‐effectiveness.Implications for practiceFuture plans for expansion or development of DSPD and similar services need to have cost‐effectiveness of agreed outcomes assessed as a central element.

Correlating DFT‐Calculated Energy Barriers to Experiments in Nonheme Octahedral FeIVO Species
Authors: Cho Kyung‐Bin , Kim Eun Jeong , Seo Mi Sook , Shaik Sason , Nam Wonwoo 
Published: June 2012

AbstractThe experimentally measured bimolecular reaction rate constant, k2, should in principle correlate with the theoretically calculated rate‐limiting free energy barrier, ΔG≠, through the Eyring equation, but it fails quite often to do so due to the inability of current computational methods to account in a precise manner for all the factors contributing to ΔG≠. This is further aggravated by the exponential sensitivity of the Eyring equation to these factors. We have taken herein a pragmatic approach for CH activation reactions of 1,4‐cyclohexadiene with a variety of octahedral nonheme FeIVO complexes. The approach consists of empirically determining two constants that would aid in predicting experimental k2 values uniformly from theoretically calculated electronic energy (ΔE≠) values. Shown in this study is the predictive power as well as insights into energy relationships in FeIVO CH activation reactions. We also find that the difference between ΔG≠ and ΔE≠ converges at slow reactions, in a manner suggestive of changes in the importance of the triplet spin state weight in the overall reaction.

AbstractPhthalocyanine compounds of novel type based on a bridged bis‐ligand, denoted “intracavity” complexes, have been prepared. Complexation of clamshell ligand 1,1′‐[benzene‐1,2‐diylbis(methanediyloxy)]bis[9(10),16(17),23(24)‐tri‐tert‐butylphthalocyanine] (clam,tBuPc2H4, 1) with lanthanide(III) salts [Ln(acac)3]⋅n H2O (Ln=Eu, Dy, Lu; acetylacetonate) led to formation of double‐deckers clam,tBuPc2Ln (2 a–c). Formation of high molecular weight oligophthalocyanine complexes was demonstrated as well. The presence of an intramolecular covalent bridge affecting the relative arrangement of macrocycles was shown to result in specific physicochemical properties. A combination of UV/Vis/NIR and NMR spectroscopy, MALDI‐TOF mass‐spectrometry, cyclic voltammetry, and spectroelectrochemistry provided unambiguous characterization of the freshly prepared bis‐phthalocyanines, and also revealed intrinsic peculiarities in the structure–property relationship, which were supported by theoretical calculations. Unexpected NMR activity of the paramagnetic dysprosium complex 2 b in the neutral π‐radical form was observed and examined as well.
A General and High‐Yield Galvanic Displacement Approach to AuM (M=Au, Pd, and Pt) Core–Shell Nanostructures with Porous Shells and Enhanced Electrocatalytic Performances
Authors: Kuai Long , Geng Baoyou , Wang Shaozhen , Sang Yan 
Published: June 2012

AbstractIn this work, we utilize the galvanic displacement synthesis and make it a general and efficient method for the preparation of AuM (M=Au, Pd, and Pt) core–shell nanostructures with porous shells, which consist of multilayer nanoparticles. The method is generally applicable to the preparation of AuAu, AuPd, and AuPt core–shell nanostructures with typical porous shells. Moreover, the AuAu isomeric core–shell nanostructure is reported for the first time. The lower oxidation states of AuI, PdII, and PtII are supposed to contribute to the formation of porous core–shell nanostructures instead of yolk‐shell nanostructures. The electrocatalytic ethanol oxidation and oxygen reduction reaction (ORR) performance of porous AuPd core–shell nanostructures are assessed as a typical example for the investigation of the advantages of the obtained core–shell nanostructures. As expected, the AuPd core–shell nanostructure indeed exhibits a significantly reduced overpotential (the peak potential is shifted in the positive direction by 44 mV and 32 mV), a much improved CO tolerance (If/Ib is 3.6 and 1.63 times higher), and an enhanced catalytic stability in comparison with Pd nanoparticles and Pt/C catalysts. Thus, porous AuM (M=Au, Pd, and Pt) core–shell nanostructures may provide many opportunities in the fields of organic catalysis, direct alcohol fuel cells, surface‐enhanced Raman scattering, and so forth.

Published: June 2012

AbstractMesenchymal stem cells (MSCs) are capable of self‐renewal and multilineage differentiation. A periodic acid–Schiff (PAS) stain‐based assay was developed to screen for small‐molecule inducers of hepatic differentiation of bone marrow MSCs. 2‐(4‐Bromophenyl)‐N‐(4‐fluorophenyl)‐3‐propyl‐3H‐imidazo[4,5‐b]pyridin‐5‐amine (SJA710‐6) was identified as a novel small molecule able to induce the differentiation of rat MSCs (rMSCs) toward hepatocyte‐like cells in vitro, where rMSCs treated with SJA710‐6 have typical morphological and functional characteristics of hepatic cells, including glycogen storage, urea secretion, uptake of low density lipoprotein (LDL) and expression of hepatocyte‐specific genes and proteins. Expression of FoxH1 (FAST1/2) induces the differentiation of rMSCs towards hepatocyte‐like cells, suggesting that this gene plays an important role in the hepatic fate specification of rMSCs.

AbstractDye‐sensitized photoelectrosynthesis cells (DSPECs) represent a promising approach to solar fuels with solar‐energy storage in chemical bonds. The targets are water splitting and carbon dioxide reduction by water to CO, other oxygenates, or hydrocarbons. DSPECs are based on dye‐sensitized solar cells (DSSCs) but with photoexcitation driving physically separated solar fuel half reactions. A systematic basis for DSPECs is available based on a modular approach with light absorption/excited‐state electron injection, and catalyst activation assembled in integrated structures. Progress has been made on catalysts for water oxidation and CO2 reduction, dynamics of electron injection, back electron transfer, and photostability under conditions appropriate for water splitting. With added reductive scavengers, as surrogates for water oxidation, DSPECs have been investigated for hydrogen generation based on transient absorption and photocurrent measurements. Detailed insights are emerging which define kinetic and thermodynamic requirements for the individual processes underlying DSPEC performance.
Human amygdala development in the absence of species‐expected caregiving
Authors: Tottenham Nim 
Published: June 2012

AbstractIn altricial species, like the human, caregiver presence is necessary for typical emotional development. Children who have been raised in institutional care early in life experience caregiver deprivation and are at significantly elevated risk for emotional difficulties. The current manuscript examines the non‐human and human literatures on amygdala development following caregiver deprivation and presents an argument that in the absence of the species‐expected caregiver presence, human amygdala development exhibits rapid development and perhaps premature engagement that results in some of the emotional phenotypes observed following early institutional care. © 2012 Wiley Periodicals,Inc.

Sensorless sinusoidal wave drive for control of power factor of PM motor by detection of inverter bus current
Authors: Matsushita Motoshi , Kameyama Hiroyuki , Ikeboh Yasuhiro , Morimoto Shigeo 
Published: June 2012

AbstractPermanent‐magnet synchronous motors (PMSMs) with sinusoidal back EMF are widely used in domestic appliances for the reduction of acoustic noise and energy consumption. PMSMs are generally controlled with a sinusoidal waveform current. Typically, PMSMs are controlled by vector‐controlled sinusoidal drives, which require substantial computational resources. Hence, simpler sinusoidal wave drives such as V/f drives, which control the phase difference between the voltage and the current (the power factor of the PM motor), have been proposed for controlling PMSMs, This paper presents a new method that does not require current sensors but can be used to estimate the phase difference by sampling the voltage of the shunt resistor, which is used to detect the overcurrent supplied to the inverter. This method allows for detection of the current and accurate estimation and appropriate control of the phase difference. Using this method, we were able to control the phase difference and achieve high efficiency, cost reduction, and high reliability. © 2012 Wiley Periodicals, Inc.

Dependence of internal pressure rise due to arc on current waveform and ignition position
Authors: Tanaka Shin‐Ichi , Miyagi Tsukasa , Iwata Mikimasa , Amakawa Tadashi 
Published: June 2012

AbstractThis paper describes an experimental study concerning the pressure rise due to high current arcs in a closed chamber. In this study, the arcs were ignited in certain chambers of varying size under the same conditions, namely, an arc current of 12.5 kA and an arc duration of 0.1 s. Moreover, the pressure rises in the chambers were measured while varying the current waveform, namely, the frequency of the AC power source and the DC component of the current, and the ignition position. Based on each measured waveform, not only the maximum value $\Delta {P_{{\rm{max}}}}$ but also the middle value $\Delta {P_{{\rm{mid}}}}$, which was the midpoint of the amplitude around the time point of $\Delta {P_{{\rm{max}}}}$, were extracted. As a result of the evaluation using both $\Delta {P_{{\rm{max}}}}$ and $\Delta {P_{{\rm{mid}}}}$, it was shown that $\Delta {P_{{\rm{max}}}}/\Delta {P_{{\rm{mid}}}}$ varied with both the current waveform and the ignition position, whereas $\Delta {P_{{\rm{mid}}}}$ was independent of them. Through FFT analysis of both the pressure rise and the arc power waveforms, it was verified that this experimental result was related to the resonance effect between the pressure rise and the arc power oscillations. © 2012 Wiley Periodicals, Inc.

Insensitive Nitrogen‐Rich Energetic Compounds Based on the 5,5′‐Dinitro‐3,3′‐bi‐1,2,4‐triazol‐2‐ide Anion
Authors: Dippold Alexander A. , Klapötke Thomas M. , Winter Nils 
Published: June 2012

AbstractIn this contribution the improvements achieved in the synthesis of the thermally stable energetic heterocycle 5,5′‐dinitro‐2H,2′H‐3,3′‐bi‐1,2,4‐triazole (DNBT) are described. The main goal was the synthesis of at least equally stable but more powerful energetic compounds based on the DNBT2– anion in combination with nitrogen‐rich cations. A complete structural and spectroscopic characterization, including IR, Raman, and multinuclear NMR analyses of the uncharged compound is presented. In addition, X‐ray crystallographic measurements on DNBT revealed a very high density of 1.903 g cm–3. To increase both performance and stability, highly nitrogen‐rich salts of DNBT formed from ammonium, hydroxyammonium, hydrazinium, guanidinium, aminoguanidinium and triaminoguanidinium cations were prepared and fully characterized by vibrational and multinuclear NMR spectroscopy, DSC, and X‐ray diffraction measurements. The standard enthalpies of formation were calculated for selected compounds at the CBS‐4M level of theory and the detonation parameters were calculated by using the EXPLO5.5 program. In addition, the impact as well as friction sensitivities and sensitivity against electrostatic discharge were determined.
Planar rocking response and stability analysis of an array of free‐standing columns capped with a freely supported rigid beam
Authors: Makris Nicos , Vassiliou Michalis F. 
Published: June 2012

SUMMARYThis paper investigates the planar rocking response of an array of free‐standing columns capped with a freely supported rigid beam in an effort to explain the appreciable seismic stability of ancient free‐standing columns that support heavy epistyles together with the even heavier frieze atop. Following a variational formulation, the paper concludes to the remarkable result that the dynamic rocking response of an array of free‐standing columns capped with a rigid beam is identical to the rocking response of a single free‐standing column with the same slenderness yet with larger size, that is a more stable configuration. Most importantly, the study shows that the heavier the freely supported cap beam is (epistyles with frieze atop), the more stable is the rocking frame regardless of the rise of the center of gravity of the cap beam, concluding that top‐heavy rocking frames are more stable than when they are top light. This ‘counter intuitive’ finding renders rocking isolation a most attractive alternative for the seismic protection of bridges with tall piers, whereas its potential implementation shall remove several of the concerns associated with the seismic connections of prefabricated bridges.

AbstractBackgroundPercutaneous endoscopic gastrostomy (PEG) is a relatively safe procedure and is an important supportive treatment for patients with advanced head and neck cancer. Although tumor seeding has been reported in various sites, seeding at the PEG exit site is a rare complication.Methods and ResultsWe describe a clinical case in which squamous cell carcinoma of the hypopharynx implanted at the site of PEG insertion and was successfully removed by surgery. PEG was previously placed by the “pull” technique. A review of the literature, discussion of the mechanism of spread, and recommendations to avoid this complication are discussed.ConclusionsTo avoid this rare and poor prognostic complication, the “pull” technique should be avoided for PEG placement in any patient with head and neck squamous cell carcinoma. An alternative method such as the “push” technique should be preferred. © 2012 Wiley Periodicals, Inc. Head Neck, 2013
Targeted therapy: The new lease on life for acute promyelocytic leukemia, and beyond
Authors: Chen Sai‐Juan , Zhou Guang‐Biao 
Published: June 2012

AbstractLeukemia, a group of hematological malignancies characterized by abnormal proliferation, decreased apoptosis, and blocked differentiation of hematopoietic stem/progenitor cells, is a disease involving dynamic change in the genome. Chromosomal translocation and point mutation are the major mechanisms in leukemia, which lead to production of oncogenes with dominant gain of function and tumor suppressor genes with recessive loss of function. Targeted therapy refers to treatment strategies perturbing the molecules critical for leukemia pathogenesis. The t(15;17) which generates PML‐RARα, t(8;21) that produces AML1‐ETO, and t(9;22) which generates BCR‐ABL are the three most frequently seen chromosomal translocations in myeloid leukemia. The past two to three decades have witnessed tremendous success in development of targeted therapies for acute and chronic myeloid leukemia caused by the three fusion proteins. Here, we review the therapeutic efficacies and the mechanisms of action of targeted therapies for myeloid leukemia and show how this strategy significantly improve the clinical outcome of patients and even turn acute promyelocytic leukemia from highly fatal to highly curable. © 2012 IUBMB IUBMB Life, 64(8): 671–675, 2012
DO INTERNATIONAL NON‐GOVERNMENTAL ORGANIZATIONS WALK THE TALK? RECONCILING THE ‘TWO PARTICIPATIONS’ IN INTERNATIONAL DEVELOPMENT
Authors: Brunt Carol , McCourt Willy 
Published: June 2012

AbstractInternational non‐governmental organizations (INGOs) espouse principles of participation and empowerment, for the most part applied to INGOs' beneficiaries rather than their staff. Evidence from a study of seven INGOs operating in Kenya indicates that beneficiaries participate much less, and staff somewhat more, than INGO rhetoric would suggest. Although participation of both groups was limited, beneficiary involvement was episodic at best, whereas staff had continuous, albeit constrained access to regular meetings and other fora. The need to be accountable to donors was a major limiting factor. However, all stakeholders, including donors, share an interest in achieving long‐term results, and the evidence from the literature and our own empirical findings is that participation facilitates achieving those results. Thus, our study suggests that the ‘two participations’ can be reconciled through a focus on the long‐term interests of INGOs' intended beneficiaries. Copyright © 2012 John Wiley & Sons, Ltd.
The Effects of Coding Bias on Estimates of Behavioural Similarity in Crime Linking Research of Homicides
Authors: Pakkanen Tom , Zappalà Angelo , Grönroos Caroline , Santtila Pekka 
Published: June 2012

AbstractThis study explored whether a coding bias due to knowledge of which crimes have been committed by the same offender exists when behavioural variables are coded in serial murder cases. The study used an experimental approach where the information given to the participants (N = 60) concerning correct linkages between a number of murder series was manipulated. The participants were divided into three different groups (n = 20 in each). These three groups received correct, incorrect, or no information about the linked series prior to the coding. The results showed that there is no clear evidence to support the hypothesis of a bias in the coding. The risk of expectancy effects and suggestions on how to minimise them in behavioural crime linking research were discussed, and suggestions on how to improve the validity of possible future replications of the experiment were given. The practical implications of expectancy effects on behavioural crime linking decisions for the justice system were also discussed. Copyright © 2012 John Wiley & Sons, Ltd.
