Emotion and Self‐Cutting: Narratives of Service Users Referred to a Personality Disorder Service
Authors: Morris Charlotte , Simpson Jane , Sampson Mark , Beesley Frank 
Published: October 2013

Theory and existing research suggest that emotion regulation capabilities develop during the formative years. Emotion dysregulation is associated with psychological distress and may contribute towards difficulties such as personality disorder and self‐harm. This study aimed to explore the contexts in which individuals' narratives of emotional experience and self‐harm developed. Eight participants who cut themselves and were seen by a personality disorder service were recruited. Semi‐structured interviews were carried out, and interview transcripts were analysed using a narrative approach.Five temporal themes were generated: ‘Seen and not heard’, ‘A big release … to get rid of all the pain and hurt’, ‘A vicious circle’, ‘A different world’ and ‘Trying to turn my life around’. The findings highlight how early experiences may have led participants to perceive emotions as unacceptable and subsequently suppress emotion in adulthood. Suppression of emotions appeared to be related to appraisals of emotions and to secondary emotional distress. Furthermore, cutting was linked to suppression of emotions as well as negative self‐beliefs formed during childhood and reinforced through subsequent experiences. The study emphasizes the need for therapeutic approaches to focus on emotions when working with individuals who self‐cut. Furthermore, the findings indicate the need for compassionate and validating health services that may help service users develop more optimistic future narratives.

Focusing on emotions in therapy rather than self‐harming behaviour per se may be beneficial for individuals who self‐cut.
Encouraging abstinence from cutting, without first helping clients learn emotion regulation skills, may lead to more serious self‐cutting.
Pride or Embarrassment? Employees’ Emotions and Corporate Social Responsibility
Authors: Onkila Tiina 
Published: October 2013

AbstractThis study explores how the employees of a financial firm use emotional arguments to construct different views of their employer's corporate social responsibility (CSR). It is theoretically based on the recent literature regarding employee perspectives of CSR, and especially on the role of emotions in CSR. Furthermore, the study utilizes rhetorical theory as a framework for data analysis. A qualitative study, based on face‐to‐face interviews, was conducted among 27 employees in a Finnish financial firm. The study identifies six categories of emotional arguments the employees used to construct views of where their employing organization's CSR is derived from. These categories relate positive emotions to satisfaction with the employing organization's CSR and negative emotions to dissatisfaction. The results show that employees also experience external pressures for CSR, but only implicitly, because they do not wish be embarrassed by their employer.

Are Socially Responsible Behaviors Paid Off Equally? A Cross‐cultural Analysis
Authors: del Mar Miras‐Rodríguez María , Carrasco‐Gallego Amalia , Escobar‐Pérez Bernabé 
Published: October 2013

AbstractBased on the strong influence that national culture has on corporate social and responsibility (CSR) actions (institutional theory), it is necessary to study how the financial outcomes of CSR actions could be affected by these cultural characteristics. This fact is particularly interesting for managers whose companies operate in different cultures given that they have to deal with this aspect. The aim of this paper is to analyze the moderator role that national culture could have on the CSR and firm performance (CSR‐FP) relationship through a meta‐analysis, hence helping to clarify the debate existing about this relationship in the literature. The results show that this relationship is greatly affected by national culture. In this sense, countries with a high assertiveness and gender egalitarianism show a very negative relationship. Nevertheless, those with a higher future orientation, institutional collectivism, and a humane orientation reveal a positive correlation which reaches its maximum value in those countries with a high uncertainty avoidance.

A Method for Creating Microporous Carbon Materials with Excellent CO2‐Adsorption Capacity and Selectivity
Authors: Qian Dan , Lei Cheng , Wang En‐Min , Li Wen‐Cui , Lu An‐Hui 
Published: October 2013

AbstractA new synthetic approach for the fabrication of microporous carbon materials (HCMs) by using discrete chelating zinc species as dynamic molecular porogens to create extra micropores that enhance their CO2‐adsorption capacity and selectivity is reported. During the carbonization process, the evaporation of the in situ‐formed Zn species would create additional nanochannels that contribute to the additional micropore volume for CO2 adsorption. The resultant HCMs show an increased number of micropores, with sizes in the range 0.7–1.0 nm and a high CO2‐adsorption capacity of 5.4 mmol g−1 (23.8 wt %) at 273 K and 3.8 mmol g−1 (16.7 wt %) at 298 K and 1 bar, which are superior to those of most carbon‐based adsorbents with N‐doping or high specific surface areas. Dynamic gas‐separation measurements, by using 16 % CO2 in N2 (v/v) as a feedstock, demonstrated that CO2 could be effectively separated from N2 under ambient conditions and shows a high separation factor (S=110) for CO2 over N2, thereby reflecting a strongly competitive CO2‐adsorption capacity. If the feedstock contained water vapor, the dynamic capacity of CO2 was almost identical to that measured under dry conditions, thus indicating that the carbon material had excellent tolerance to humidity. Easy CO2 release could be realized by purging an argon flow through the fixed‐bed adsorber at 298 K, thus indicating good regeneration ability.

Authors: Hong Jindui , Wang Yongsheng , Wang Yabo , Zhang Wei , Xu Rong 
Published: October 2013

AbstractA NiS/C3N4 photocatalyst containing earth‐abundant elements only was constructed by means of a simple hydrothermal method. This photocatalyst shows efficient hydrogen evolution (48.2 μmol h−1) under visible light when using triethanolamine as a sacrificial reagent. The optimal loading of 1.1 wt % NiS on C3N4 as a cocatalyst can enhance the H2 production by about 250 times compared with the native C3N4. The highest apparent quantum efficiency of 1.9 % was recorded at 440 nm.
A sub‐1 V nanopower temperature‐compensated sub‐threshold CMOS voltage reference with 0.065%/V line sensitivity
Authors: Magnelli Luca , Crupi Felice , Corsonello Pasquale , Iannaccone Giuseppe 
Published: October 2013

AbstractWe present the design of a nanopower sub‐threshold CMOS voltage reference and the measurements performed over a set of more than 70 samples fabricated in 0.18 µm CMOS technology. The circuit provides a temperature‐compensated reference voltage of 259 mV with an extremely low line sensitivity of only 0.065% at the price of a less effective temperature compensation. The voltage reference properly works with a supply voltage down to 0.6 V and with a power dissipation of only 22.3 nW. Very similar performance has been obtained with and without the inclusion of the start‐up circuit. Copyright © 2013 John Wiley & Sons, Ltd.
FFT‐based calibration method for 1.5 bit/stage pipelined ADCs
Authors: Lee Shuenn‐Yuh , Liang Ming‐Chun , Hsieh Cheng‐Han 
Published: October 2013

SummaryA fast Fourier transform (FFT)‐based digital calibration method for 1.5 bit/stage pipeline analog‐to‐digital converter (ADC) is proposed in this paper. Capacitor mismatch and finite gain of the operational amplifier (OPAMP) can be overcome by the proposed calibration method. Given that the capacitor mismatch and the finite OPAMP gain cause the radix of all the stages of 1.5 bit/stage pipeline ADC to become unequal to 2, the FFT processor can be adopted to evaluate the actual radixes of all the stages and then generate new digital output to compensate for error caused by these non‐ideal effects. Moreover, as capacitor mismatch and the finite gain of OPAMP can be compensated, low‐gain OPAMP can be used in high‐performance ADC to reduce power dissipation; a small capacitor can then be adopted to save on space. An example of a 10 bit 1.5 bit/stage pipelined ADC with only an 8 bit circuit performance is implemented in 0.18 µm TSMC CMOS process. Circuit measurement result reveals that the signal‐to‐noise‐and‐distortion ratio of 51.03 dB with 11 dB improvement after calibration can be achieved at the sample rate of 1 MHz.

Performance of a Zero Average Dynamics‐controlled buck converter using different pulse‐width modulation schemes
Authors: D'Amico María Belén , Angulo Fabiola 
Published: October 2013

SummaryThe response of a digital Zero Average Dynamics (ZAD)‐controlled buck converter under the variation of its intrinsic parameters as well as the pulse‐width modulation signal is studied in detail. The multiparameter analysis presented here leads to a complete knowledge of the different dynamical scenarios exhibited by the system. Numerical results indicate that the success of the ZAD‐strategy is highly dependent on the parameter and pulse‐width modulation (PWM) combinations. Experiments are included to validate the performance inside the so‐called optimum region. Copyright © 2013 John Wiley & Sons, Ltd.
From “truly naïve” to “exhausted senescent” T cells: When markers predict functionality
Authors: Larbi Anis , Fulop Tamas 
Published: October 2013

AbstractThe study of T cell biology has been accelerated by substantial progress at the technological level, particularly through the continuing advancement of flow cytometry. The conventional approach of observing T cells as either T helper or T cytotoxic is overly simplistic and does not allow investigators to clearly identify immune mechanisms or alterations in physiological processes that impact on clinical outcomes. The complexity of T cell sub‐populations, as we understand them today, combined with the immunological and functional diversity of these subsets represent significant complications for the study of T cell biology. In this article, we review the use of classical markers in delineating T cell sub‐populations, from “truly naïve” T cells (recent thymic emigrants with no proliferative history) to “exhausted senescent” T cells (poorly proliferative cells that display severe functional abnormalities) wherein the different phenotypes of these populations reflect their disparate functionalities. In addition, since persistent infections and chronological aging have been shown to be associated with significant alterations in human T cell distribution and function, we also discuss age‐associated and cytomegalovirus‐driven alterations in the expression of key subset markers. © 2013 International Society for Advancement of Cytometry

AbstractMultiple scientific disciplines require the isolation of specific subsets of blood cells from patient samples for gene expression analysis by microarray or RNA‐sequencing, preserving disease‐ or treatment‐related signatures. However, little is known with respect to the impact of different cell isolation methods on gene expression and the effects of positive selection, negative selection, and fluorescence activated cell sorting (FACS) have not previously been assessed in parallel. To address this knowledge gap, CD4+ T cells, CD8+ T cells, B cells, and monocytes were isolated from blood samples from five independent donors using positive immunomagnetic selection, negative immunomagnetic selection, and FACS. We hypothesized that positive selection and FACS would yield higher purity but may have an impact on gene expression since both methods utilize antibodies that bind surface receptors of the cell type of interest. Moreover, FACS might upregulate stress response genes due to passage of the cells through the sorter. Microarray gene expression data were generated and subjected to unsupervised clustering and differential gene expression analysis. Surprisingly, these analyses revealed that gene expression signatures were more similar between cells isolated by negative selection and FACS compared to cells isolated by positive selection. Moreover, genes that are involved in the response to stress generally had the highest expression in cells isolated by negative or positive selection and not FACS. Thus, FACS is the recommended method for isolation of leukocyte subsets for gene expression studies since this method results in the purest subset populations and does not appear to induce a stress response. © 2013 International Society for Advancement of Cytometry
DNA damage signaling, impairment of cell cycle progression, and apoptosis triggered by 5‐ethynyl‐2′‐deoxyuridine incorporated into DNA
Authors: Zhao Hong , Halicka H. Dorota , Li Jiangwei , Biela Ewa , Berniak Krzysztof , Dobrucki Jurek , Darzynkiewicz Zbigniew 
Published: October 2013

AbstractThe “click chemistry” approach utilizing 5‐ethynyl‐2′‐deoxyuridine (EdU) as a DNA precursor was recently introduced to assess DNA replication and adapted to flow‐ and imaging‐cytometry. In the present study, we observed that EdU, once incorporated into DNA, induces DNA damage signaling (DDS) such as phosphorylation of ATM on Ser1981, of histone H2AX on Ser139, of p53 on Ser15, and of Chk2 on Thr68. It also perturbs progression of cells through the cell cycle and subsequently induces apoptosis. These effects were observed in non‐small cell lung adenocarcinoma A549 as well as in B‐cell human lymphoblastoid TK6 and WTK1 cells, differing in the status of p53 (wt versus mutated). After 1 h EdU pulse‐labeling, the most affected was cells progression through the S phase subsequent to that at which they had incorporated EdU. This indicates that DNA replication using the template containing incorporated EdU is protracted and triggers DDS. Furthermore, progression of cells having DNA pulse‐labeled with EdU led to accumulation of cells in G2, likely by activating G2 checkpoint. Consistent with the latter was activation of p53 and Chk2. Although a correlation was observed in A549 cells between the degree of EdU incorporation and the extent of γH2AX induction, such correlation was weak in TK6 and WTK1 cells. The degree of perturbation of the cell cycle kinetics by the incorporated EdU was different in the wt p53 TK6 cells as compared to their sister WTK1 cell line having mutated p53. The data are thus consistent with the role of p53 in modulating activation of cell cycle checkpoints in response to impaired DNA replication. The confocal microscopy analysis of the 3D images of cells exposed to EdU for 1 h pulse and then grown for 24 or 48 h revealed an increased number of colocalized γH2AX and p53BP1 foci considered to be markers of DNA double‐strand breaks and enlarged nuclei. © 2013 International Society for Advancement of Cytometry

Authors: Saxena Anshul , Shrivastava Akansha , Akashe Shyam 
Published: October 2013

SUMMARYIn the complementary metal oxide semiconductor (CMOS) nanoscale technology ground bounce noise and power consumption are becoming important metric. In presented paper, low leakage Schmitt trigger circuits are proposed for wave shaping or cleaning process with low ground bounce noise. Schmitt trigger play important role in communication electronics. Power‐gating and stacking power‐gating techniques have provided for maintaining the parameter of Schmitt trigger. An ideal approach has been investigated with stacking power‐gating technique. For further reduction in peak of ground bounce noise during sleep to active (power) mode transition, we have performed simulations using cadence specter 45 nm standard CMOS technology at nominal temperature (27°C) with supply voltage Vdd = 0.7 V and input voltage vary from 0.7 V to 1.5 V. The simulation results show that a proposed design provide efficient 6 T and 4 T Schmitt triggers in term of minimum leakage power (8.18 fW), active power (17.80 pW), ground bounce noise (1.65 μV) and propagation delay (1.98 ns), transconductance (4.51 × 10−14 S), voltage gain (29.44 dB), hysteresis width (11.07 V) and efficiency (64.68%).

Multiple access interference and multipath interference analysis of orthogonal complementary code‐based ultra‐wideband systems over multipath channels
Authors: Bai Zhiquan , Zhao Fang , Wang Changhui , Wang Cheng‐Xiang 
Published: October 2013

SUMMARYIn order to alleviate multiple access interference and multipath interference of ultra‐wideband (UWB) system, we propose the orthogonal complementary code (OCC)‐based direct‐sequence UWB system and offset‐stacking (OS)‐UWB system. OCC has perfect partial autocorrelation and cross‐correlation characteristics. With the application of OCC in UWB system, we can obtain better performance in multiple access interference and multipath interference. The proposed OS‐UWB structure can also achieve variable data rate transmission because of its innovative OS spreading technique. Theoretical analysis and simulation results show that the proposed UWB system can achieve excellent performance and outperform the unitary code‐based direct‐sequence UWB system.

Cryptanalysis of a dynamic identity‐based remote user authentication scheme with verifiable password update
Authors: Li Xiong , Niu Jianwei , Liao Junguo , Liang Wei 
Published: October 2013

SUMMARYIn the authentication scheme, it is important to ensure that the user's identity changed dynamically with the different sessions, which can protect the user's privacy information from being tracked. Recently, Chang et al. proposed an untraceable dynamic identity‐based remote user authentication scheme with verifiable password update. However, our analysis show that the property of untraceability can easily be broken by the legal user of the system. Besides, we find the scheme of Chang et al. vulnerable to offline password guessing attack, impersonation attack, stolen smart card attack, and insider attack.

Provable secure identity‐based multi‐proxy signature scheme
Authors: Sahu Rajeev Anand , Padhye Sahadeo 
Published: October 2013

SummaryMulti‐proxy signature is one of the useful primitives of the proxy signature. Till now, only a few schemes of identity‐based multi‐proxy signature (IBMPS) have been proposed using bilinear pairings, but most of the schemes are insecure or lack a formal security proof. Because of the important application of IBMPS scheme in distributed systems, grid computing, and so on, construction of an efficient and provable‐secure IBMPS scheme is desired. In 2005, Li & Chen proposed an IBMPS scheme from bilinear pairings, but their paper lacks a formal model and proof of the security. Further, in 2009, Cao & Cao presented an IBMPS scheme with the first formal security model for it. Unfortunately, their scheme is not secure against the Xiong et al's attack. In this paper, first, we present an IBMPS scheme, then we formalize a security model for the IBMPS schemes and prove that the presented scheme is existential unforgeable against adaptive chosen message and identity attack in the random oracle model under the computational Diffie–Hellman assumption. Also, our scheme is not vulnerable for the Xiong et al's attack. The presented scheme is more efficient in the sense of computation and operation time than the existing IBMPS schemes.

Toward energy‐proportional Internet core networks: an energy‐minimized routing and virtual topology design for Internet protocol layer
Authors: Wu Yuansheng , Guo Bing , Shen Yan , Wang Jihe , Liu Xiaobin 
Published: October 2013

SummaryWith the exponential growth of Internet traffic, the energy consumption issue of core networks is increasingly becoming critical. Today's core networks are highly underutilized most of the time because of the over‐provisioning and redundancy dimensioning, which results in severe energy inefficiency. In previous work, many non‐deterministic polynomial‐time hard mathematics formulation models have been proposed to minimize the energy consumption of core networks. However, effective heuristics are needed to solve these models in medium/large‐size networks. This work studies the energy‐minimized routing and virtual topology design problem of the power‐hungry Internet protocol (IP) layer in core networks, aiming to achieve an energy‐proportional IP layer by exploiting the variation of traffic with hours to reconfigure virtual topology and reroute traffic. We formulate energy‐minimized routing and virtual topology design as an Integer linear programming problem and propose a LR algorithm, a heuristic based on the Lagrangian relaxation, to solve this problem in a polynomial‐time. The simulation results indicate that the LR algorithm outperforms the best previous algorithm and can achieve a near energy‐proportional IP layer with significant power saving. Furthermore, a detailed analysis of simulation results is conducted, which suggests a design principle of network equipment to facilitate the power saving. Copyright © 2013 John Wiley & Sons, Ltd.
An efficient pairing‐free identity‐based authenticated group key agreement protocol
Authors: Tan Zuowen 
Published: October 2013

SummaryAn authenticated group key agreement protocol allows participants to agree on a group key that will be subsequently used to provide secure group communication over an insecure network. In this paper, we give a security analysis on a pairing‐free identity‐based authenticated group key agreement because of Islam et al. We show that the protocol of Islam et al. cannot satisfy the minimal security requirements of the key agreement protocols. We propose an efficient pairing‐free identity‐based authenticated group key agreement for imbalanced mobile network. The proposed protocol can be implemented easily for practical application in mobile networks as it is free from bilinear. Under the difficulty of the InvCDH and CDH we demonstrate that the proposed protocol provides perfect forward secrecy, implicit key authentication and the dynamic functionality. As compared with the group key agreement protocols for imbalanced mobile network, the proposed protocol provides stronger security properties and high efficiency.
