Hysteresis settling technique for CMOS comparators based on substrate voltage
Authors: Rodrigues C.R. , Muller C. , Neto D.J. Monteiro 
Published: January 2013

A hysteresis is a widely employed solution to mitigate the effect of noise on comparators. Presented is a very simple technique, applicable to any topology of MOS differential comparator. It consists of imposing different bulk‐source voltage to the input MOS differential pair. Depending on the polarity of the input signal, one substrate is connected to the rail voltage and the other to a reference control voltage. So, when the slope inverts the connections are switched through pMOS switches. Simulation results show that the hysteresis up to 302,6 mV can be linearly controlled for bulk voltages ranging from 0 to 500 mV, for XFAB 0.35XH technology. Finally, an aproximation for the control rule is proposed.

Authors: Dadashi F. , Millet G.P. , Aminian K. 
Published: January 2013

Presented is an accurate swimming velocity estimation method using an inertial measurement unit (IMU) by employing a simple biomechanical constraint of motion along with Gaussian process regression to deal with sensor inherent errors. Experimental validation shows a velocity RMS error of 9.0 cm/s and high linear correlation when compared with a commercial tethered reference system. The results confirm the practicality of the presented method to estimate swimming velocity using a single low‐cost, body‐worn IMU.

Authors: Yun D. , Yun K.‐S. 
Published: January 2013

The energy harvester is an attractive power source for wireless portable electronics, especially in applications for handheld and wearable electronic devices. Proposed is a woven piezoelectric structure for possible application as a wearable energy harvester. The proposed device consists of polymer column threads and a piezoelectric film weaving them into stitches in the row. Polymer patches are alternately patterned on the upper and bottom sides of the piezoelectric film, where the charges are generated when subjected to a stretching and contraction motion. A maximum peak power density of 0.63 mW/cm2 was obtained from repeated stretching and contraction motion at an operation frequency of 8 Hz.

Authors: Pagano Maria E. , White William L. , Kelly John F. , Stout Robert L. , Tonigan J. Scott 
Published: January 2013

This study investigates the 10-year course and impact of Alcoholics Anonymous (AA)-related helping (AAH), step-work, and meeting attendance on long-term outcomes. Data were derived from 226 treatment-seeking alcoholics recruited from an outpatient site in Project MATCH and followed for 10 years post treatment. Alcohol consumption, AA participation, and other-oriented behavior were assessed at baseline, end of the 3-month treatment period, and 1, 3, and 10 years post treatment. Controlling for explanatory baseline and time-varying variables, results showed significant direct effects of AAH and meeting attendance on reduced alcohol outcomes and a direct effect of AAH on improved other-oriented interest.
Olanzapine Abuse
Authors: Kumsar Neslihan Akkişi , Erol Atila 
Published: January 2013

Olanzapine is a thienobenzodiazepine that blocks especially the serontonin (5-hydroxytryptamine [5-HT]) 5-HT2A and the dopamine D2 receptors as well as muscarinic (M1), histamine (H1), 5-HT2C, 5-HT3 to 5-HT6, adrenergic (αl), and D4 receptors. This case report presents an olanzapine abuse. A 48-year-old, primary school graduate, married woman applied to psychiatry clinic with tachycardia, insomnia, and anxiety complaints. In psychiatric evaluations, it was determined that these complaints have been continuing for 15 years at intervals and that she has been using citalopram 40 mg/day and olanzapine 50 mg/day for the last 3 years. As diabetes mellitus was diagnosed in follow-ups, interruption of olanzapine treatment was planned. The patient stated that she started taking the medicine again upon discomfort, increase in anxiety, dysphoria, insomnia, and nervousness, which started just after olanzapine was interrupted. She said that she was feeling dense stress when she did not take the medicine, and she thought that this situation would recover only by taking that medicine and hence she could not discontinue the medicine. In addition to medications with obvious abuse potential such as benzodiazepines and methylphenidate, and other stimulants, abuse of a number of commonly prescribed psychiatric medications has been reported. There are only 2 cases of olanzapine abuse in literature.
Sparsely correlated hidden Markov models with application to genome-wide location studies
Authors: Choi Hyungwon , Fermin Damian , Nesvizhskii Alexey I. , Ghosh Debashis , Qin Zhaohui S. 
Published: January 2013

AbstractMotivation: Multiply correlated datasets have become increasingly common in genome-wide location analysis of regulatory proteins and epigenetic modifications. Their correlation can be directly incorporated into a statistical model to capture underlying biological interactions, but such modeling quickly becomes computationally intractable.Results: We present sparsely correlated hidden Markov models (scHMM), a novel method for performing simultaneous hidden Markov model (HMM) inference for multiple genomic datasets. In scHMM, a single HMM is assumed for each series, but the transition probability in each series depends on not only its own hidden states but also the hidden states of other related series. For each series, scHMM uses penalized regression to select a subset of the other data series and estimate their effects on the odds of each transition in the given series. Following this, hidden states are inferred using a standard forward–backward algorithm, with the transition probabilities adjusted by the model at each position, which helps retain the order of computation close to fitting independent HMMs (iHMM). Hence, scHMM is a collection of inter-dependent non-homogeneous HMMs, capable of giving a close approximation to a fully multivariate HMM fit. A simulation study shows that scHMM achieves comparable sensitivity to the multivariate HMM fit at a much lower computational cost. The method was demonstrated in the joint analysis of 39 histone modifications, CTCF and RNA polymerase II in human CD4+ T cells. scHMM reported fewer high-confidence regions than iHMM in this dataset, but scHMM could recover previously characterized histone modifications in relevant genomic regions better than iHMM. In addition, the resulting combinatorial patterns from scHMM could be better mapped to the 51 states reported by the multivariate HMM method of Ernst and Kellis.Availability: The scHMM package can be freely downloaded from http://sourceforge.net/p/schmm/ and is recommended for use in a linux environment.Contact: ghoshd@psu.edu or zhaohui.qin@emory.eduSupplementary information: Supplementary data are available at Bioinformatics online.
The food system, climate change and CSR: from business to government case
Authors: Sodano Valeria , Hingley Martin 
Published: January 2013

PurposeThis theoretical research article aims to take an economics approach to set out the role of the food system and its importance in control of greenhouse gases (GHG) and contribution to climate change. The article seeks to challenge the weak position of public policy aimed at tackling this major issue and the shortcomings of reliance on food corporations' voluntary and sporadic approach based on corporate social responsibility (CSR).Design/methodology/approachA review of literature and analysis of the legal and economic theories of the firm show how both public and private intervention tends to be ineffective in facing the many problems raised by climate change within the food sector. This article proposes a “government case” for CSR.FindingsIt is argued that interventions to tackle climate change are political rather than economic and depend on power relationships among different actors, such as states and large corporations, involved in their implementation. The main conclusion of the article is that a renovated agenda to tackle climate change ought to be based on the two pillars of soft regulation‐voluntary CSR and binding state regulation. In this new scenario corporate and antitrust laws should be used to correct the growing imbalance between corporate rights and corporate responsibility, with binding regulations supporting voluntary CSR.Originality/valueApplication of CSR has been left to corporations which have pursued their own piecemeal agenda; and the predominant creed of neoliberalism has been ineffectual in governance. This article questions its effectiveness and proposes an original and potentially sustainable alternative.
Impact of corporate social responsibility claims on consumer food choice
Authors: Mueller Loose Simone , Remaud Hervé 
Published: January 2013

PurposeThe study seeks to assess the impact of two different corporate social responsibility (CSR) claims, relating to social and environmental dimensions, on consumers' wine choice across international markets. It analyses how point of purchase CSR claims compete with other food claims and their awareness, penetration and consumers' trust are examined.Design/methodology/approachA discrete choice experiment with a visual shelf simulation was used to elicit consumer preferences and to estimate marginal willingness to pay for CSR and other food claims across the UK, France, Germany, the US East Coast, the US Midwest, and Anglophone and Francophone Canada.FindingsCSR claims relating to social and environmental responsibility have a similar awareness, penetration and consumer trust, but differ in their impact on consumer choice, where environmental corporate responsibility claims benefit from a higher marginal willingness to pay. Consumer valuation of CSR claims significantly differs across international markets, but is consistently lower than for organic claims.Originality/valueThis is the first cross‐national study that analyses the impact of CSR claims on consumer food choice relative to other food claims using large representative consumer samples. The strength of the paper also pertains to the utilisation of innovative choice experiments covering a large range of choice relevant product attributes.
Building commitment through reflective practice: an inside‐out approach
Authors: Yeo Roland K. 
Published: January 2013

PurposeThe purpose of this paper is to (re)introduce the concept of Community of Commitment and Practice (CoCP) and to discuss the types of learning that occur in the process. It describes the differences between CoCP and the commonly‐known Community of Practice (CoP), emphasizing the power of commitment as crucial for organizational development.Design/methodology/approachA Singapore case study was used as a basis for identifying the conceptual and practical relevance of CoCP to organizational practice. A literature review based on relevant concepts provides the theoretical perspective for understanding the occurrence of learning in organizational contexts.FindingsCoCP promotes reflective action learning and reflective action taking driven by an inside‐out approach. Intrinsic learning is largely influenced by the intent and motivation of individuals rather than a top‐down (outside‐in) approach.Practical implicationsThe reflective inquiry and collaborative learning process of CoCP help build individuals as agents of change as they not only seek to do things differently but also influence others to make the organization a better workplace. In turn, they become reflective practitioners as they view constraints as opportunities for further learning to achieve specific outcomes.Originality/valueThe usefulness of CoCP is supported by relevant research and its impact on organizations is wide ranging. The paper elucidates an integrative perspective of the CoCP processes, providing a roadmap for developing the learning organization.

Published: January 2013

PurposeThe purpose of this paper is to design and develop a business dynamics model in entrepreneurial orientation for employees (EOE).Design/methodology/approachThe mental model uses the casual loops, stock and flow diagrams in the business dynamics model. Hiring rate, Quit rate, Skill rate, Skill growth rate, EOE skill inventory rate, Performance rate etc. were defined and used with EOE metrics governing the model. VENSIM software package was used to simulate and validate the model using sensitivity analysis. The case study method was used to experiment a pre/post EOE training intervention with employees in an ITES organisation in India. Using a validated EOE questionnaire, data were captured from employees in an ITES organisation in Chennai, for validation of business dynamics model.FindingsThe time frame for imparting initial EOE training and retraining time after EOE training were simulated and results were summarised.Research limitations/implicationsFuture researchers can extend this work and apply in other industries and geographies also. Any organisation can customise and utilise the business dynamics EOE model as per their requirementsPractical implicationsThe model facilitates the measurement of both individual employee performance as well as organisational performance. The EOE business dynamics model contributes to the development of two indices namely entrepreneurial orientation for employees index (EOEI) and organisational performance index (OPI). The policy planners, human resource strategists, management consultants can utilise the business dynamics EOE model for effective decision making, budgetary allocations towards training initiatives and so on.Originality/valueThe model is a novel and first of its kind using business dynamics in entrepreneurial orientation for employees. The human resource planners can use this model for forecasting the man power needs as well as skill development, employee empowerment and organisational development.

The study and comparison includes thermal infrared sensors used by snakes, echolocation used by bats and dolphins, and navigation methods used by birds. Countermeasures used by prey to avoid capture are also considered.FindingsSome animals have remote sensing and navigation capabilities that are considerably more efficient than those provided by the human body or designed by man.Practical implicationsSensor designers may be encouraged to use the biometic approach in the design of new sensors.Social implicationsThe paper provides a better understanding of animal behaviour, especially their unique abilities to remotely sense, echolocate and navigate with high accuracy over considerable distances.Originality/valueThe paper presents a comparison of remote sensors used by animals with those developed by humans. Remote sensor designers can learn to improve their sensor designs by studying animal sensors within a biomimetic framework.
The comparison of expressed satisfaction and expectations of potential real estate buyers in Slovenia and Japan
Authors: Grum Bojan , Temeljotov Salaj Alenka 
Published: January 2013

PurposeThe purpose of this paper is to present partial results of a survey conducted in Slovenia and Japan. Its aim is to determine factors, which have a decisive influence on potential acquirers of real estate rights when deciding to purchase real estate. Discussed is the role of personal expectations and the role of satisfaction of potential acquirers of real estate rights regarding factors related to the real estate in which participants live and according to their different cultural identity.Design/methodology/approachThe authors follow the hypothesis that differences in personal expectations and expressed satisfaction of potential acquirers of real estate rights regarding real estate factors according to different cultural identity are statistically significant. The main instrument for measuring the participants' expectations is a questionnaire in which 1,270 participants took part.FindingsBy analysing the results of statistical analyses, the hypothesis is confirmed. Results show that Slovene participants compared to Japanese participants express a higher satisfaction level with the current real estate in which they live and at the same time lower expectations regarding practically all real estate factors. The article explains the difference of the higher expressed satisfaction with the difference in the level of residential estate ownership, which is higher in Slovenia. Also explained is the lower expectations of Slovene participants, with the conclusion that less than one‐third of Slovene participants are willing to give up certain key factors in case of a lower real estate price.Research limitations/implicationsThere are potential risks of error arising from the use of assumptions, limited samples size and data from the secondary resources.Originality/valueThe major contribution of this paper is showing that expressed participants' high satisfaction with residential status does not necessarily generate high expectations regarding real estate factors.
Principal contractor involvement in post‐occupancy evaluation in the UK construction industry
Authors: Williams Tristan , Bouchlaghem Dino , Loveday Dennis , Law Charlie 
Published: January 2013

PurposeClient satisfaction is a key element of repeat business and for securing future work in the construction industry. There are areas still in need of improvement for contractors; these areas include the handover process to clients and the subsequent aftercare and organisational learning. Post‐occupancy evaluation (POE) offers an opportunity for a holistic perspective towards continual improvement in construction. While the challenges of POE have been well documented in the design phase, the role of the principal contractor in this area has been under‐researched. The purpose of this paper is to investigate the role of the contractor in the POE process and to identify good practice in improving the building environment for the end users.Design/methodology/approachThe research comprised a comprehensive review of current literature with a focus on existing practices. The review highlighted a need for further research into contractor involvement in POE in the UK construction industry. An electronic questionnaire survey was produced and distributed to the United Kingdom Contractors Group. Subsequent semi‐structured interviews were conducted with willing participants from the survey, to further investigate the responses to the survey.FindingsThe key findings from the research highlighted the lack of contractor involvement in POE and insufficient knowledge on how or when to conduct POE on a project. Many of the barriers to POE identified by previous research are not applicable to contractor involvement in POE. The majority of construction professionals believe that POE is time intensive and that there is difficulty in interpreting the information collected from POE. Dissemination of information internally and externally has the potential to offer significant value to organisational and individual development of all stakeholders involved in the process.Practical implicationsThe findings are likely to be of interest to designer's facilities management professionals and those involved in construction. Contractors should view POE as a business opportunity to improve the end output for the client and end‐users and not as another expensive problem.Originality/valueThis paper addresses the perceptions of POE within the major UK contractor group. It identifies relevant barriers to POE in the construction process and highlights the lack of POE penetration into the wider construction industry. The research has highlighted that POE has the potential to improve contractor performance and add value to end users of new projects. It has identified that previous research has focused on consultant‐led research as opposed to contractor‐led.

Published: January 2013

PurposeThe purpose of this paper is to establish the influences of the colours red and blue on perceived well being, social cohesion and productivity in complex real life work conditions during regular meetings.Design/methodology/approachIn total, seven regular government teams held seven regular meetings in red, blue and reference meeting rooms. In literature it is often mentioned that red is a warm and blue a cool colour. To be able to test the warmth and coldness effects the authors have amplified the warm and cold qualities with light colour and colour of the table top desk. The employees were asked to complete questionnaires concerning perceived well being, social cohesion and productivity. In total, 52 subjects completed three questionnaires, at the start, the end and two or three days after the meeting. Data were analysed with SPSS 16.FindingsThe findings did not show any effects of the red and blue environment on perceived well being, social cohesion and productivity. The authors assume the processes in real life work situations are too complex to measure influences.Research limitations/implicationsThe research focuses on individual perceptions and did not measure actual well being, social cohesion and productivity.Practical implicationsPractical implications are that statements frequently mentioned in literature concerning influences of red and blue might be not valid in real life meeting settings. New ways of testing the impact of colours should be reconsidered. Because lab situations are too simplified and artificial, the authors suggest testing influences of colour in an isolated setting in relation to art.Originality/valueThe originality of this research concerns testing colour influences in complex real life work settings, such as meetings.
