Effect of annealing at room temperature on the surface resistivity of elastomer/multiwalled carbon nanotube nanocomposites
Authors: Lee Sang‐Young , Kim Gue‐Hyun 
Published: February 2016

In this study, thermoplastic polyurethane (TPU) and ethylene propylene diene terpolymer (EPDM) were melt‐mixed with multi walled carbon nanotube (MWCNT), respectively. The change in the surface resistivity of the nanocomposites during annealing at room temperature was examined. The surface resistivity of TPU/MWCNT nanocomposites with 3 and 5 phr MWCNT and uncrosslinked EPDM/MWCNT nanocomposites with 4 and 6 phr MWCNT significantly increases with increasing annealing time at room temperature. To delay the increase of surface resistivity during annealing at room temperature, silica was added to the TPU/MWCNT and EPDM/MWCNT nanocomposites. The rate of increase in the surface resistivity during annealing at room temperature was much slower with addition of silica to the nanocomposites. POLYM.

Psychological intervention targeting distress for cancer patients: a meta‐analytic study investigating uptake and adherence
Authors: Brebach Rachel , Sharpe Louise , Costa Daniel S. J. , Rhodes Paul , Butow Phyllis 
Published: February 2016

AbstractObjectiveAlthough cancer care guidelines recommend screening for distress among cancer patients and offering psychological support when indicated, many patients decline offers of such support. This study aimed to quantify uptake and adherence to psychological support and to identify predictors of each.MethodsSearches were conducted in Embase, Medline, PsychInfo and Scopus to identify studies reporting uptake or adherence rates for individual psychological interventions targeting distress, anxiety or depression for cancer patients or survivors.ResultsAcross the 53 included studies reporting uptake and/or adherence rates for 12 323 cancer patients, the uptake and adherence rates were 60.1% and 90.4%, respectively. Patients screened and identified as distressed were less likely to accept intervention than unselected patients (50.3% compared with 66.3%, Q(1) = 4.66, P = 0.031). Uptake of therapy was higher for interventions delivered by telephone rather than face‐to‐face (71.2% compared with 53.8%, Q(1) = 4.91, P = 0.027) and when therapy was offered prior to medical treatment compared with later (72.9% compared with 56.8%, Q(1) = 5.60, P = 0.018). Patients were more likely to accept intervention from nurses than other allied health professionals (68.3% compared with 50.5%, Q(1) = 5.76, P = 0.016).ConclusionsPatients appeared more receptive to interventions offered near diagnosis, over the telephone and by nurses. Although this suggests higher acceptability of such interventions, evidence of their greater efficacy is lacking, and this merits further investigation. Research is needed to understand barriers to acceptance of psychological support, particularly because uptake rates were lower for distressed patients. Copyright © 2016 John Wiley & Sons, Ltd.
On the application of generic CCA‐secure transformations to proxy re‐encryption
Authors: Nuñez David , Agudo Isaac , Lopez Javier 
Published: February 2016

AbstractSeveral generic methods exist for achieving chosen‐ciphertext attack (CCA)‐secure public‐key encryption schemes from weakly secure cryptosystems, such as the Fujisaki–Okamoto and REACT transformations. In the context of proxy re‐encryption (PRE), it would be desirable to count on analogous constructions that allow PRE schemes to achieve better security notions. In this paper, we study the adaptation of these transformations to proxy re‐encryption and find both negative and positive results. On the one hand, we show why it is not possible to directly integrate these transformations with weakly secure PRE schemes because of general obstacles coming from both the constructions themselves and the security models, and we identify 12 PRE schemes that exhibit these problems. On the other hand, we propose an extension of the Fujisaki–Okamoto transformation for PRE, which achieves a weak form of CCA security in the random oracle model, and we describe the sufficient conditions for applying it.

A multiple imputation approach for MNAR mechanisms compatible with Heckman's model
Authors: Galimard Jacques‐Emmanuel , Chevret Sylvie , Protopopescu Camelia , Resche‐Rigon Matthieu 
Published: February 2016

Standard implementations of multiple imputation (MI) approaches provide unbiased inferences based on an assumption of underlying missing at random (MAR) mechanisms. However, in the presence of missing data generated by missing not at random (MNAR) mechanisms, MI is not satisfactory. Originating in an econometric statistical context, Heckman's model, also called the sample selection method, deals with selected samples using two joined linear equations, termed the selection equation and the outcome equation. It has been successfully applied to MNAR outcomes. Nevertheless, such a method only addresses missing outcomes, and this is a strong limitation in clinical epidemiology settings, where covariates are also often missing.We propose to extend the validity of MI to some MNAR mechanisms through the use of the Heckman's model as imputation model and a two‐step estimation process. This approach will provide a solution that can be used in an MI by chained equation framework to impute missing (either outcomes or covariates) data resulting either from a MAR or an MNAR mechanism when the MNAR mechanism is compatible with a Heckman's model. The approach is illustrated on a real dataset from a randomised trial in patients with seasonal influenza. Copyright © 2016 John Wiley & Sons, Ltd.
The Impact of Origins of Reverse Technology Transfer on MNC Home‐Country Product Development
Authors: Hsu Sean T. , Iriyama Akie 
Published: February 2016

AbstractReverse technology transfer (the transferring of multinational corporation [MNC] subsidiaries’ technological knowledge to their home country) deserves more executive attention since the source of competitive advantage of MNCs resides in their capabilities to leverage knowledge from different units across borders. This article examines three salient “origins” of reverse technology transfer—headquarters, local constituents, and subsidiary research and development (R&D) activity—and their impact on MNCs’ home‐country product development. We argue that reverse technology transfer from subsidiary R&D activity is more likely to have a positive impact on MNC home‐country product development than the other two origins because reverse transfer from local constituents requires high integration cost, and transfer from headquarters adds little technological novelty. We also develop two contingency hypotheses for the latter two origins to increase their likelihood of positive impacts on home‐country product development. Using a data set of 1,331 Taiwanese MNCs, our empirical evidence provides two important messages to managers: (1) a subsidiary whose technology mainly relies on its R&D would be an ideal target for reverse transfer; and (2) reverse transfer from local constituents and headquarters can be effective when they fit with an appropriate organizational mechanism, such as governance mode and absorptive capacity. © 2016 Wiley Periodicals, Inc.

The rise of the starlet sea anemone Nematostella vectensis as a model system to investigate development and regeneration
Authors: Layden Michael J. , Rentzsch Fabian , Röttinger Eric 
Published: February 2016

Reverse genetics and next‐generation sequencing unlocked a new era in biology. It is now possible to identify an animal(s) with the unique biology most relevant to a particular question and rapidly generate tools to functionally dissect that biology. This review highlights the rise of one such novel model system, the starlet sea anemone Nematostella vectensis. Nematostella is a cnidarian (corals, jellyfish, hydras, sea anemones, etc.) animal that was originally targeted by EvoDevo researchers looking to identify a cnidarian animal to which the development of bilaterians (insects, worms, echinoderms, vertebrates, mollusks, etc.) could be compared. Studies in Nematostella have accomplished this goal and informed our understanding of the evolution of key bilaterian features. However, Nematostella is now going beyond its intended utility with potential as a model to better understand other areas such as regenerative biology, EcoDevo, or stress response. This review intends to highlight key EvoDevo insights from Nematostella that guide our understanding about the evolution of axial patterning mechanisms, mesoderm, and nervous systems in bilaterians, as well as to discuss briefly the potential of Nematostella as a model to better understand the relationship between development and regeneration. Lastly, the sum of research to date in Nematostella has generated a variety of tools that aided the rise of Nematostella to a viable model system. We provide a catalogue of current resources and techniques available to facilitate investigators interested in incorporating Nematostella into their research.

The potential influence of sustainability criteria on the European Union pellets market—the example of Sweden
Authors: Hansson Julia , Hackl Roman 
Published: February 2016

The introduction of sustainability criteria for solid biomass/biofuels on the European Union (EU) or global level may influence the EU pellets market, e.g., by limiting the eligible biomass supply potential or specific pellet chains. This assessment focuses on greenhouse gas (GHG) emission reductions and the issue of sustainable forest management (SFM) for pellets potentially used in Sweden (for residential and/or industrial use). The paper includes (1) a literature review of recent studies addressing the impact of sustainability requirements (for solid biomass and/or liquid biofuels) on the bioenergy market, (2) a characterization of SFM conditions in potential pellets export countries and their capacity to enforce respective legislation, and (3) an assessment of GHG emissions for heat and electricity for the Swedish market from selected potential wood pellet chains (including torrefaction) and related GHG emissions reduction compared to fossil fuels using a life cycle assessment perspective. Most of the assessed wood pellet value chains will most likely be able to meet stringent sustainability requirements from a GHG perspective. Thus, the impact of near‐term GHG emission reduction demands on the Swedish pellets market is limited. More specifically, we find that torrefaction may be advantageous for pellets imported over long distances (i.e., over approximately 18,500 km). We conclude that demand for SFM related to solid biofuels will not have a significant or long‐lasting effect on the market for Swedish pellets. The real impacts of sustainability requirements will however depend on levels of ambition as well as the methodologies and systems boundaries applied in future systems.

First known satellite collaring of a viverrid species: preliminary performance and implications of GPS tracking Malay civets (Viverra tangalunga)
Authors: Evans Meaghan N. , Guerrero‐Sanchez Sergio , Bakar Mohd Soffian Abu , Kille Peter , Goossens Benoit 
Published: February 2016

AbstractThe application of advanced technologies to the study of little‐known species is a necessary step in generating effective conservation strategies. Despite the biological importance of the small carnivore guild, a paucity of data exists in terms of the spatial ecology of these species, largely due to logistical constraints of large and bulky collar units. This study reports the first known satellite collaring of a viverrid, the Malay civet (Viverra tangalunga), in Sabah, Malaysian Borneo. Stationary tests of two generations of 65–70 g e‐obs GmbH ‘Collar 1A’ units recorded high fix success rates and good accuracy and precision under semi‐open canopy. From October 2013–August 2015, nine adult V. tangalunga were fit with e‐obs collars recording hourly nocturnal GPS locations. Collars were successfully deployed for 27–187 days. Field GPS fix success varied from 22 to 88.3 %, with the study documenting a total GPS success of 58.1 % across all individuals. Despite this large in‐field performance range, the quality and quantity of data collected by these units surpass that of previous VHF studies on Asian viverrids, collecting on average a 16‐fold increase in locations per collaring day. The successful application of satellite technology to these little‐known carnivores carries significant biological and conservation implications, and it is recommended that satellite collars are a viable technology to conduct detailed and well‐designed ecological studies of Viverridae species.
Semantic communication in birds: evidence from field research over the past two decades
Authors: Suzuki Toshitaka N. 
Published: February 2016

AbstractWhat do animal signals mean? This is a central question in studies on animal communication. Research into the semantics of animal signals began in 1980, with evidence that alarm calls of a non‐human primate designated predators as external referents. These studies have challenged the historical assumption that such referential signaling is a unique feature of human language and produced a paradigm shift in animal communication research. Over the past two decades, an increasing number of field studies have revealed similar complexity in anti‐predator communication of birds. The acoustic structures of avian alarm calls show a high degree of variation in pitch, duration, shape, and repetition rate. In addition to such distinct and graded variations, several birds combine discrete types of notes or calls into higher complex sequences. These variations in alarm calls are typically associated with the predator's attributes, such as predator type and distance, and receivers respond to them with appropriate anti‐predator behaviors. Although alarm calls of several bird species, as well as those of monkeys, appear to denote predator attributes, almost nothing is known about the cognitive processes that underlie the production and perception of these signals. In this review, I explore the existing evidence for referential signaling in birds and highlight the importance of the cognitive approach to animal communication research. I hope this review will promote further investigations of alarm‐calling behavior in birds and will help enhance our understanding of the ecology and evolution of semantic communication.
Normal values and standardization of parameters in nuclear cardiology: Japanese Society of Nuclear Medicine working group database

Published: February 2016

Abstract
As a 2-year project of the Japanese Society of Nuclear Medicine working group activity, normal myocardial imaging databases were accumulated and summarized. Stress-rest with gated and non-gated image sets were accumulated for myocardial perfusion imaging and could be used for perfusion defect scoring and normal left ventricular (LV) function analysis. For single-photon emission computed tomography (SPECT) with multi-focal collimator design, databases of supine and prone positions and computed tomography (CT)-based attenuation correction were created. The CT-based correction provided similar perfusion patterns between genders. In phase analysis of gated myocardial perfusion SPECT, a new approach for analyzing dyssynchrony, normal ranges of parameters for phase bandwidth, standard deviation and entropy were determined in four software programs. Although the results were not interchangeable, dependency on gender, ejection fraction and volumes were common characteristics of these parameters. Standardization of 123I-MIBG sympathetic imaging was performed regarding heart-to-mediastinum ratio (HMR) using a calibration phantom method. The HMRs from any collimator types could be converted to the value with medium-energy comparable collimators. Appropriate quantification based on common normal databases and standard technology could play a pivotal role for clinical practice and researches.
First Successful Pregnancy After Pre-implantation Genetic Diagnosis by FISH for an Inversion Together with a Cryptic Translocation in India

AbstractThe technique of pre-implantation genetic diagnosis (PGD) by fluorescence in situ hybridization (FISH) in cases of repeated miscarriages due to parental balanced inversions and translocations is relatively new in India. In a couple with a history of recurrent miscarriages and implantation failures, karyotyping done in three laboratories showed that the husband had an insertion or inversion of chromosome 12. Hence, they were referred to us for PGD. The anomaly turned out to be more complex. A pre-PGD workup using a series of FISH probes on metaphases accompanied by reflex FISH was required to characterize the anomaly. For subsequent PGD, single blastomeres were biopsied from seven embryos obtained by intracytoplasmic sperm injection. FISH analysis had to be carried out using ten probes in four rounds. On pre-PGD workup for inversion 12 by FISH, an additional anomaly of a cryptic translocation between 9qter and 12qter was detected in the husband. His complex karyotype according to the detailed ISCN nomenclature was therefore 46,XY,t(9;12)(9pter→9q34.1::12q24.2→12qter),der(12)inv(12)(12pter→12p11.2::12q24.2→12p11.2::9q34.1→9qter). After PGD, the normal and balanced embryos transferred, resulted in the birth of healthy twins conceived in the first cycle itself. Therefore, a pre-PGD workup is important and needs reflex FISH in the event of an unexpected cytogenetic anomaly. PGD will need the analysis of additional chromosomes on the same cell by FISH in such cases. An experienced in vitro fertilization and Genetics team is essential for success. This is the first report of PGD by FISH for an inversion coupled with a cryptic translocation from India.
Which proportion of SR investments is enough? A survey-based approach
Authors: Dorfleitner Gregor , Nguyen Mai 
Published: February 2016

AbstractThis article examines the determinants of the optimal percentage that private investors seek to invest in a socially responsible (SR) way when forming their portfolio. By conducting a global online survey in English, German and French, we find indications that it is sufficient for the majority of investors to have a certain amount of their budget invested sustainably. Accordingly, the optimal proportion tends to be lower the higher the available investment volume is. In addition, the non-financial utility derived from SR investments appears to be independent of the form of financing the investor provides. Moreover, the results show that well-educated women and slightly younger persons seek to invest a higher percentage of their portfolio socially responsibly.

AbstractIn Taiwan, the number of new cases of human immunodeficiency virus (HIV) infection via drug injection has been increasing since 2003. Due to HIV and hepatitis B virus (HBV) having similar transmission routes, HBV and HIV infections among injecting drug users (IDUs) has become an important public health issue. The aim of this study was explore the prevalence of HBV infection among IDUs with and without HIV infection, and examine whether HIV infection is associated with HBV infection among IDUs in Southern Taiwan. We enrolled 566 IDUs, including 87 anti‐HBV positive IDUs and 479 anti‐HBV negative IDUs, and also analyzed the results of liver function tests, HBV DNA, anti‐HIV, HIV RNA, and CD4 cell count. The results showed that the prevalence of HBV infection among IDUs was 15.4%. The prevalence of hepatitis B surface antigen (HBsAg) was higher among individuals born before 1985 (15.9% vs. 4.0%), but this was not significant. Anti‐HIV seropositivity was related to HBsAg seropositivity [odds ratio (OR) = 2.47, 95% confidence interval = 1.26–4.82, p = 0.008). Anti‐HCV and anti‐HIV were risk factors for abnormal alanine aminotransferase (ALT; OR = 2.11, 95% confidence interval = 1.005–4.42, p = 0.048 and OR = 1.47, 95% confidence interval = 1.02–2.10, p = 0.04, respectively), and HBsAg was not a factor related to abnormal ALT. In conclusion, the prevalence of HBV infection was similar in the general population and in IDUs, and due to anti‐HIV seropositivity being significantly related to HBsAg seropositivity, HBV infection among IDUs is still important. We suggest that for IDUs, HBsAg should be monitored closely.
