Opioid dependence and intimate partner violence: associations with the current parenting behavior of fathers
Authors: Smith Stover Carla , J. McMahon Thomas 
Published: February 2014

Purpose– Because the concurrent nature of chronic drug abuse (DA) and intimate partner violence (IPV) is frequently ignored in research examining the correlates of the two conditions, the purpose of this paper is designed to document differences in parenting behavior associated with a history of DA vs a history of IPV in fathers.Design/methodology/approach– An ethnically diverse sample of 91 opioid-dependent fathers receiving methadone maintenance treatment and a demographically similar group of 111 fathers living in the same community with no history of alcohol or DA since the birth of their first child were interviewed using a set of standard research measures.Findings– Multivariate analysis of covariance revealed that, after allowance for demographic covariates, a history of either minor or severe IPV, but not a history of DA, was associated with a report of more negative parenting behavior. A history of minor IPV was associated primarily with a lack of warmth and affection in parenting behavior. A history of severe IPV was associated with more aggressive and more neglectful parenting behavior.Originality/value– Within a statistical model that allowed for the extent to which DA and IPV can co-occur during the family career of men, the results of this study suggested that IPV, more so than DA, was associated with parenting behavior representing risk for abuse and neglect of children. Clinical intervention with high-risk fathers need to be grounded in a better understanding of the potential influence of DA and IPV on the parenting behavior of men at risk for child abuse and neglect.
Substance misuse, mental health problems and recurrent child maltreatment
Authors: Laslett Anne-Marie , Room Robin , Dietze Paul 
Published: February 2014

Purpose
– The purpose of this paper is to determine whether the diagnosis of both carers’ mental health problems and substance misuse increase the likelihood of recurrent child maltreatment over and above the individual effects of these factors.

Design/methodology/approach
– Retrospective secondary data analysis of 29,455 children where child maltreatment was confirmed in the Victorian child protection system between 2001 and 2005. Recorded mental health, alcohol misuse and other drug misuse variables were entered into multivariate logistic regression models predicting repeated child maltreatment. Interactions and a range of other child, carer and socio-economic factors were included in these models.

Findings
– Carer alcohol misuse, other drug misuse and mental ill health all independently predicted recurrent child maltreatment. The presence of both other drug misuse and mental ill health increased the likelihood that recurrent child abuse was recorded over the likelihood that mental health alone predicted recurrent child maltreatment, and while alcohol misuse had an effect when there was no mental health condition recorded it did not have an additional effect when there was evidence of mental health problems.

Research limitations/implications
– Children in families where there is both mental health problems and other drug use problems are at greater risk of repeated maltreatment than where there is evidence of mental health problems or other drug use alone. Where there was evidence of carer mental health problems, alcohol misuse did not add to this likelihood. However, the effect of mental health and other drug use was similar in size to the effect of alcohol misuse alone.

Originality/value
– These findings add to understandings of the effects of co-occurring mental health problems and substance misuse on recurrent child maltreatment and differentiate between cases that involve alcohol and other drug misuse.
Maritime City: using serious gaming to deliver child protection training
Authors: Davies Jonathon 
Published: February 2014

Purpose– The purpose of this paper is to discuses the development and application of Maritime City, a developing virtual urban community created by the University of Greenwich to supplement the delivery of child protection training.Design/methodology/approach– Maritime City is a “serious game” developed by the University of Greenwich to deliver child protection training to health and social care professionals working with children and their families. This discussion paper will consider the practice landscape for these professionals and their training needs for working with families where children are at risk of harm. This paper will also consider some of the innovative pedagogical approaches to providing this training through the use of a serious game. Finally, this paper will also share some of the thinking behind the work and several of the learning activities that have been used with students.Findings– Maritime City offers a safe, new medium to explore and reflect upon child protection assessment in a family situation. It offers health and social care professionals, at all stages of their careers, a unique opportunity to evaluate child protection issues. Amongst its advantages, Maritime City gives professionals involved in child protection the opportunity to evaluate and re-evaluate a case without putting children or service users at risk. As the game is in the early stages of use further evaluations are required to discern its effects on practice.Originality/value– Maritime offers a unique opportunity of completing a child protection home visit using a range of tools to help participants draw on their own experiences and those of others to prepare them for working with children and families.

Authors: Rose Lexy , Breen Olivia , Webb Zillah 
Published: February 2014

Purpose– The purpose of this paper is to evaluate the usefulness of a Healthy Living Group (HLG) for individuals with learning disabilities and mental health problems in an inpatient setting.Design/methodology/approach– Seven sessions were developed. Each session focussed on a different aspect of healthy living, and used psychoeducation and practical skill building to enable individuals to create personalized healthy living plans. Quantitative post-intervention measures and a qualitative focus group were used to determine group participants’ learning and enjoyment.Findings– Principles about healthy living were successfully taught in an enjoyable way to individuals with learning disabilities. Factors that enhanced learning and those that created barriers to developing healthy living plans are explored.Practical implications– Individuals with learning disabilities and mental health problems can be supported to develop personalized healthy living plans. Recommendations for further adaptations to the group structure are made, in order to enable others to run successful groups.Originality/value– The HLG is the first of its kind to be developed for individuals with learning disabilities.
Investigating suicide as a career response
Authors: J. Duff Angus , C.A. Chan Chris 
Published: February 2014

Purpose– To empirically consider work and career as potential influences of suicide.Design/methodology/approach– In this qualitative study we conducted in-depth semi-structured interviews with 16 individuals who were survivors (i.e. family members or intimates) of individuals who had committed suicide. Data was analyzed using a grounded theory methodology.Findings– This exploratory study used purposive self-determination as the theoretical framework for analyzing their life histories. Factors of purposive self-determination, including lack of purpose, feeling controlled, experiencing failure, and social exclusion all figured prominently but differentially according to life-stage. Distinct work and career themes for early-career, mid-career and late-career suicides emerged. Early-career suicides were attributed to educational or work-related contexts, leading to a sense of hopelessness. Mid-career suicides emphasized despair based in failure. Finally, an attempt to escape from challenges associated with transitioning roles in retirements emerged as a key theme in late-career suicides.Originality/value– Although suicide has been studied extensively from medical, psychopathological, sociological, anthropological, philosophical and religious perspectives, there is a dearth of research considering why certain individuals choose to end their own lives as a result of work and career related reasons. This study sought to contribute to our understanding of this under-researched phenomenon. Additionally, while extant careers theory and research has considered positive notions of career such as career success or careers as a calling, this work presents an alternate lens, the consideration of career failure and careers as a sentence.
Bridging corporate social responsibility and compassion at work
Authors: Moon Tae-Won , Hur Won-Moo , Ko Sung-Hoon , Kim Jae-Woo , Yoon Sung-Won 
Published: February 2014

Purpose– This study aims to examine how employees' perceptions of organizational actions, such as corporate social responsibility (CSR), affect their compassionate acts in organizations through employee perceptions of organizational justice and affective organizational commitment.Design/methodology/approach– The employees from 87 firms in South Korea were surveyed using a self-administered instrument for data collection. Out of 400 questionnaires, a total of 253 usable questionnaires were obtained after list-wise deletion, for a 63.3 percent response rate. The firms belong to a variety of industries (banking and financial services, manufacturing, hospitals, education, etc.).Findings– The results indicate that employees' perceptions of CSR positively relate to compassion at work through organizational justice perceptions (i.e. perceptions of distributive justice, procedural justice, and interactional justice), and affective organizational commitment, in a sequential manner, in addition to their direct effects on compassion at work.Originality/value– This study sheds new light on both the compassion and the CSR literature due to its attempt to bridge the macro concept of CSR with micro research in compassion. This is, apparently, one of the first pieces of research in the management literature to specifically address compassion as a consequence of employees' CSR perception.
A new modeling method for S-MCSRM driven by three-phase full bridge converter
Authors: Ma Qingqing , Ge Baoming , Bi Daqiang , J.T.E. Ferreira Fernando , T. de Almeida Aníbal 
Published: February 2014

Purpose
– The S-MCSRM is a two-phase excited switched reluctance motor (SRM), with the short flux path and mutual inductance coupling, which is suitable for the oil submersible pump application owing to large torque and three-wire connection with the standard full-bridge power converter. However, there is not literature to disclose its model due to the complicated mutual inductance coupling. The FEM model is a time-consuming method to analyze this motor. For the first time, this paper aims to propose an S-MCSRM model for performance analysis and control method developing. The proposed model would save simulation time and be a theoretical fundamental for further implementing control algorithm.

Design/methodology/approach
– The S-MCSRM's operating principle is analyzed, and the voltage equation and the generated torque are deduced. The FEM is utilized to obtain the five typical magnetization curves that describe the S-MCSRM's magnetic path characteristic. The magnetic co-energy equation, phase torque and total torque equations are obtained. From the basic voltage equation, the S-MCSRM's state space model is built for the dynamic analysis and control purpose. The S-MCSRM is widely analyzed in detail by using the proposed model and comparison with the conventional SRM. JMAG finite element package is used to verify the proposed model.

Findings
– The proposed modeling method is validated by the identical results to those from FEM-based JMAG software. The proposed model just takes second-level time, which is far less than minute-level time consuming of FEM method. The S-MCSRM generates larger torque than the conventional SRM, with three-wire and standard full bridge power converter, and it is confirmed that the S-MCSRM is suitable for the oil submersible pump applications.

Originality/value
– This paper proposes a new modeling method for the S-MCSRM to exactly analyze the motor's operating performances, and also it is a theoretical fundamental for developing control algorithm. The proposed model saves much time in analysis, calculation, and simulation, when compared to the FEM method. The completed analysis including flux linkages, torque, torque-ripple, and torque-speed characteristic discloses the S-MCSRM's steady-state operating performances, which provides the deep insight for this kind of motor's applications.
A new analytical approach to predicting cycle-slipping in charge pump PLLs
Authors: Sadat Sadeghi Vahideh , Miar Naimi Hossein 
Published: February 2014

Purpose
– The linear analysis presented for the charge pump phase locked loops (CPPLLs) becomes inaccurate or incorrect where cycle slipping occurs. In this paper, an analytical approach is proposed, which explains the conditions in which cycle slipping happens. Using the analytical results, one can simply design or redesign a CPPLL to prevent or decrease cycle slipping and hence decreasing the locking time. The paper aims to discuss these issues.

Design/methodology/approach
– To obtain cycle slipping conditions, CPPLL's signals in the time domain are tracked and cycle slipping condition is investigated. Based on the proposed analysis, by comparing a simple function of system's parameters with a threshold, cycle slipping is predicted.

Findings
– The cycle slipping conditions are expressed in terms of system's parameters and the size of the input frequency step. The method is also generalized for a fast CPPLL with an aid-lock BBFC circuit. The good accuracy of the analytical predictions is verified using simulations in Matlab/Simulink.

Originality/value
– A new analytical method for cycle slipping prediction in CPPLLs is presented. A closed form equation in terms of system's parameters and input frequency step has been presented, which can predict the cycle slipping possibility in the system without a need to perform the full time-consuming simulations. This analytical method that uses the LambertW function's properties proposes a threshold to predict cycle slipping in the system. This method not only can be used by designers to predict cycle slipping but can also be used to design the CPPLL in order to remove or decrease cycle slipping. The method is also generalized for fast locking charge pump PLLs and as a case study, cycle slipping prediction in the BBFC-CPPLL is performed.

Design/methodology/approach
– After a theoretical description of the projection methods, the locally conservative projection is analytically tested and compared with the orthogonal method. In the second part, the implementation of the methods is described, and improvements are proposed. An industrial application of the present work, consisting in a magneto-thermal coupled problem, is then presented.

Findings
– The implementation of the conservative method is simpler than the implementation of the orthogonal method while presenting similar behaviour in terms of accuracy and conservation.

Originality/value
– The locally conservative method is extended to curl-conform and div-conform elements. Furthermore, three-dimensional studies are proposed.

Authors: Palanichamy Vimala , Balamurugan N.B. 
Published: February 2014

Purpose
– The purpose of this paper is to present an analytical model and simulation for cylindrical gate all around MOSFTEs including quantum effects.

Design/methodology/approach
– To incorporating the impact of quantum effects, the authors have used variational method for solving the Poisson and Schrodinger equations. The accuracy of the results obtained using this model is verified by comparing them with simulation results.

Findings
– This model is developed to provide an analytical expression for inversion charge distribution function for all regions of device operation. This expression is used to calculate the other important parameters like inversion charge centroid, threshold voltage, inversion charge, gate capacitance and drain current. The calculated expressions for the above parameters are simple and accurate. The validity of this model was checked for the devices with different dimensions and bias voltages.

Practical implications
– Simulation based on the compact physical models reduces the cost of developing a sophisticated fabrication technology and shortens the time-to-market. They may also be utilized to explore innovative device structures.

Originality/value
– This paper presents, for the first time, a compact quantum analytical model for cylindrical surrounding gate MOSFETs which predicts the device characteristics reasonably well over the entire range of device operation (above threshold as well as sub-threshold region).
Detailed and comprehensive mathematical modeling of flying-capacitor stacked multicell multilevel converters
Authors: Dargahi Vahid 
Published: February 2014

Purpose
– This study aims to propose a mathematical model for stacked multicell converters (SMCs), to be exploited in the analytic determination of natural voltage balancing dynamics of the flying-capacitor (FC) stacked multicell multilevel converters, i.e. investigations of the start-up behavior, dynamic response, and natural voltage balancing phenomenon.

Design/methodology/approach
– The crux of the proposed strategy is based on the closed-form analytic solution derivation for the switching functions used in the switching of the SMCs operated under phase disposition (PD) and phase shifted carrier (PSC) pulse width modulation (PD-PSC-PWM) technique. Hence, the suggested approach develops an analytic solution for the Fourier series and associated Fourier coefficients pertinent to the switching functions of the SMCs by obtaining the switching instants of the PD-PSC-PWM modulator in terms of Kapteyn series when the frequency of the triangular carrier waveform (fc) and that of the sinusoidal reference waveform (fr) have an integer ratio, i.e. f

c
· f

r
−1=k, k∈N.

Findings
– This approach results into a model, first order differential equation based model, which can be readily developed for the SMCs with any number of levels expediting the investigation of their performance. Furthermore, by an experimental scrutiny conducted on a 4×2-cell-nine-level topology of an SMC, it is inferred that under PD-PSC-PWM modulation technique, FC voltages balance naturally for higher number of stacks and cells, therefore the natural balancing exist for high-level SMCs.

Research limitations/implications
– Despite the sophistication of the proposed methodology and mathematical model, this study presents an alternative approach with high potential of applicability for derivation of the multilevel converter mathematical model exploiting the Kapteyn (Bessel-Fourier) series.

Practical implications
– Numeric computation results of the proposed analytic model for the SMCs and the simulation results as well as investigational measurements taken from 2×2-cell-five-level and 4×2-cell-nine-level experimental set-ups are presented in order to substantiate the suggested approach, derived model, and verification of natural balancing.

Originality/value
– This article and its innovations are original.
Yet another TOA estimation technique for IR-UWB
Authors: Djeddou Mustapha , Zeher Hichem , Nekachtali Younes 
Published: February 2014

Purpose
– The paper aims to propose a new method for estimating the time of arrival (TOA) of ultra-wideband (UWB) signals under IEEE 802.15.4a multipath channel model.

Design/methodology/approach
– The proposed approach is based on a proportionality test and consists in finding out whether two autoregressive (AR) processes, modeling two frames, are proportional or not. The latter operation uses a distance to measure the proportionality between the two AR processes.

Findings
– The developed technique may be used in two ways, sample-by-sample or block-by-block, according to the required ranging accuracy. It is important to note that the method offers flexibility between the computational load and the needed estimation accuracy. Moreover, the proposed method uses a threshold that is derived analytically according to a preset false alarm probability.

Practical implications
– Simulation experiments are conducted to assess the performance of the new TOA estimation algorithm. Thereby, the comparison is done against the well-known CLEAN algorithm for a sample-by-sample based TOA estimation and against three energy detector based receiver algorithms. The obtained results highlight the effectiveness of the developed approach.

Originality/value
– The developed TOA estimation algorithm is completely different from other techniques in the literature, and it is based on a proportionality test between two sliding frames. These latter are modeled by two AR processes. Then a distance measure is used to check whether or not the power spectral densities are proportional.
Modeling, analysis, and motor drive application of quasi-Z-source indirect matrix converter
Authors: Liu Shuo , Ge Baoming , Jiang Xinjian , Abu-Rub Haitham , Peng Fangzheng 
Published: February 2014

Purpose
– The paper aims to propose a new type of three-phase quasi-Z-source indirect matrix converter (QZSIMC) to extend the voltage gain for application in the induction motor drives.

Design/methodology/approach
– A unique H-shape quasi-Z-source network is connected between the three-phase voltage source and traditional indirect matrix converter to achieve the voltage boost and buck in a single-stage power conversion. The complete space vector modulation (SVM) method is proposed to control the proposed QZSIMC. The output voltage amplitude of quasi-Z-source network can be boosted by the shoot-through of the front-end rectifier, so the whole system's voltage gain is extended. Meanwhile, the QZSIMC modeling and quasi-Z-source impedance parameter design are developed by using the state space averaging method. The design-oriented analysis based on small signal model is used to investigate the quasi-Z-source impedance parameter's impact on the QZSIMC's dynamic performance. A simulated application example employs a 4-kW induction motor drive to verify the proposed QZSIMC, the developed modulation method and parameter design method.

Findings
– The proposed QZSIMC can achieve high voltage gain larger than one and also can fulfill buck function, which widens the induction motor drive's operation range. The simulation results verify the proposed QZSIMC and SVM and also validate the quality performance of the proposed induction motor drive and all theoretical analysis and parameter design method.

Originality/value
– The proposed QZSIMC effectively overcomes the limitation of traditional indirect matrix converter, through extending the voltage gain larger than one. The systematic principle, analysis, parameter design, and simulation verification provide the proposed QZSIMC with a feasible approach in practical induction motor drive applications.
