Preparation and performances of coated and aluminous entry boards with water-soluble resins for PCB drilling
Authors: Zhou Hu , Yu Bin , Li Ning , Zhou Jie , Luo Xiaoyang , Tang Jialin , Qin Xianzhi 
Published: December 2016

Purpose
This paper aims to provide a new drilling entry board for printed circuit board (PCB) process, superior in heat dissipation, lubrication, water solubility and hole location accuracy, achieving an excellent drilling process.

Design/methodology/approach
Using a mixture of polyethylene glycol (PEG) and water-soluble adhesives as hydrosoluble, endothermic and lubricant resins and aluminum foils as baseplates, a series of coated and aluminous entry boards (CABs) for PCB drilling was successfully prepared. The surface appearance of the entry boards was observed clearly by scanning electron microscopy (SEM). The endothermic and lubricant effects of the resins applied on the CABs was characterized by differential scanning calorimetry (DSC) and their water solubility was tested in the normal-temperature water (25°C). Moreover, the CABs’ good drilling properties were tested when they were used for PCB drilling.

Findings
The SEM analysis showed that the surfaces of the resin layers coated on the CABs whose coating thicknesses were less than 80 μm were smoother and flatter, which could improve hole location accuracy and reduce drill breakage ratio. By virtue of DSC, the endothermic and lubricant effects of the CABs were proven. The fusion of PEG in the resin layers could absorb the heat produced by drilling, restrain the temperature of the drill bit and hole rising and lubricate the drill bit efficiently when a hole was being drilled, which could achieve high-quality holes with good production efficiency. The water-soluble test showed that the prepared CABs had excellent water solubility at normal temperature, enabling the resin left on the hole walls and in the flute of the drill bit to be washed away easily and thereby improving the drilling efficiency and quality. The drilling tests showed that the increase in the thickness of the CABs’ coating could improve the hole location accuracy and alleviate the bit wear. In addition, the suitable coating thickness could ensure the firm adhering of the resin coating the aluminum foil, effectively avoid drill intertwist and prevent the resin debris from blocking the drilled holes on the surface of the entry board, which could hinder chip removal, resulting in poor hole wall quality and drill breakage.

Originality/value
This paper has a remarkably high industrial practicality in the PCB manufacture process.
The tool-wear characteristics of flexible printed circuit board micro-drilling and its influence on micro-hole quality
Authors: Zheng Lijuan , Wang Chengyong , Zhang Xin , Huang Xin , Song Yuexian , Wang Kefeng , Zhang Lunqiang 
Published: December 2016

Purpose
Micro-holes are drilled and plated in flexible printed circuit boards (FPCs) for connecting circuits from different layers. More holes, with diameters smaller than 0.3 mm, are required to be drilled in smaller areas with flexible circuits’ miniaturization. The micro-hole quality of micro-drilling is one of the biggest issues of the flexible circuit manufacturers’ production. However, it is not easy to control the quality of micro-holes. The purpose of this study was to conduct research on the tool wear characteristics of FPC drilling process and its influence on micro-hole quality to improve the micro-hole quality of FPC.

Design/methodology/approach
The tool-wear characteristics of micro-drills after FPC drilling were observed. The influence of spindle speed, feed rate, number of drilled holes and entry board materials on tool-wear was analyzed. The hole qualities of FPC micro-drilling were measured and observed. The relationship between tool-wear and hole quality was analyzed.

Findings
The result showed that the tool-wear characteristics of FPC micro-drilling was similar to the tool-wear characteristics of rigid printed circuit board (RPC) micro-drilling. Abrasive wear occurred on both the main cutting edges and the chisel edges of micro-drills, even though there was no glass fiber reinforcing the cloth inside FPC. Resin adhesion was observed on the chisel edge. The influence of feed and number of drilled holes on tool-wear was significant. Tool-wear significantly influences the hole quality of FPC. Tool-wear will largely decrease the hole position accuracy of FPC micro-holes. Tool-wear will increase the thickness of PI nail heads and the height of exit burrs. Fracture was the main difference between tool wear of FPC and RPC micro-drilling. Resin adhesion of RPC was much more severe than FPC micro-drilling. Increasing the spindle speed properly may improve tool life and hole quality.

Originality/value
The technology and manufacturing of FPC has been little investigated. Research on micro-drilling FPC and research data is lacking so far. The micro-hole quality directly affects the reliability of FPC. Thus, improving the micro-hole quality of FPC is very important.
Non-equidistant GM(1,1) model based on GCHM_WBO and its application in corrosion rate prediction
Authors: Zhi Yuanjie , Fu Dongmei , Wang Hanling 
Published: December 2016

Purpose
The purpose of this paper is to present a new model which combines the non-equidistant GM(1,1) model with GCHM_WBO (generalized contra-harmonic mean (GCHM); weakening buffer operator (WBO)). The authors use the model to solve the deadlock that for a large number of non-equidistant corrosion rate, it is difficult to establish a reasonable prediction model and improve the prediction accuracy.

Design/methodology/approach
This research consists of three parts: non-equidistant GM(1,1) model, GCHM_WBO operator, and the optimization of morphing parameter (contained in GCHM, control the intensity of the weakening operator). The methodology is explained as follows. First, the authors built a non-equidistant GM(1,1) model with GCHM_WBO weakened data, of which morphing parameter was randomly selected. Next, the authors calculated the error between prediction data of model and the real data, and adjusted the morphing parameter according to the error and property of GCHM. Then, the authors generated a new non-equidistant GM(1,1) based on new morphing parameter, and repeated the previous step until the termination condition was satisfied. Finally, the model with appropriate morphing parameter was used to implement the prediction of new data.

Findings
This paper finds a property of GCHM, which is a monotonic increasing function of morphing parameter in some specific conditions. Based on the property and the fixed point axiom of WBO, an algorithm was designed to search an appropriate morphing parameter. The appropriate morphing parameter was implemented for the purpose of improving the accuracy of the model. The model was applied to predict the corrosion rate of six steels at Guangzhou experimental station. The results showed that the proposed method can get more accuracy in prediction capability compared to the models with the original data and AWBO weakened data. The method is applicable to long-term forecasts in case of data scarcity.

Practical implications
Corrosion will cause huge economic loss to a country; therefore, it is important to judge the remaining useful life of a material or equipment; the foundation for judgement of which is the prediction of material corrosion rate. However, the prediction of corrosion rate is very difficult because of corrosion data’s features, such as small sample size, non-equidistant, etc. The proposed method can be used to implement long-term forecast of corrosion data with only one sample and non-equidistant samples.

Originality/value
This paper presented a model which combines the non-equidistant GM(1,1) model with GCHM_WBO to handle the problem of long-term forecasting of corrosion data. In the modelling process, the proposed morphing parameter searched through algorithm can improve the prediction accuracy of the model. Therefore, the model can provide effective and reliable result when data are of a small sample size and non-equidistant.
A literature-based intervention for women prisoners: preliminary findings
Authors: Billington Josie , Longden Eleanor , Robinson Jude 
Published: December 2016

PurposeThe purpose of this paper is to investigate whether Shared Reading (SR), a specific literature-based intervention, is transposable to a prison context and whether mental health benefits identified in other custodial and non-custodial settings were reported by women prisoners.Design/methodology/approachIn all, 35 participants were recruited within an all-female maximum security prison and attended one of two weekly reading groups. Qualitative data were collected through researcher observation of the reading groups; interviews and focus group discussions with participants and prison staff; interviews with the project worker leading the reading groups; and a review of records kept by the latter during group sessions.FindingsAttendance rates were good, with nearly half of the participants voluntarily present at =60 per cent of sessions. Two intrinsic psychological processes associated with the SR experience were provisionally identified, “memory and continuities” and “mentalisation”, both of which have therapeutic implications for the treatment of conditions like depression and personality disorder.Research limitations/implicationsLimitations included the small sample, lack of control for confounding variables, and constraints imposed on data collection by the custodial setting.Originality/valueAlthough more controlled research is required, the findings indicate that women prisoners will voluntarily engage with SR if given appropriate support, and that the intervention has potential to augment psychological processes that are associated with increased well-being.
Islamic banking presence and economic growth in Southeast Asia
Authors: Lebdaoui Hind , Wild Joerg 
Published: December 2016

Purpose
The purpose of this study is to empirically assess the relationship between Islamic banking presence in Southeast Asian countries and the economic growth.

Design/methodology/approach
The presence of Islamic banks is measured by the ratio of Islamic to conventional banking assets as well as the ratio of deposits of Islamic to conventional banking. This study starts by checking the presence of cointegration using Pedroni’s and Westerlund’s specifications; short- and long-run dynamics are further analyzed with the panel autoregressive distributed lag model (ARDL)-based estimators: pooled mean group (PMG), mean group (MG) and dynamic fixed effect (DFE). Furthermore, a two-stage regression [two-stage least squares (2SLS)] was constructed to measure the sensitivity of economic growth to the Islamic banking presence. Quarterly data from Southeast Asian countries cover the period between 2000Q1 and 2012Q4.

Findings
A long-run relationship is evident between economic growth and the Islamic banking presence in the selected region, but not in the short run. Furthermore, the Muslim population share in a given country plays a positive and statistically significant role in fueling the contribution of Islamic banking share in the financial sector on the economic growth.

Social implications
The results of this study show that Sharia-compliant banks succeeded in mobilizing additional resources for the financial sector, which may increase the stability of the banking system and the efficiency of the whole banking sector. The authors believe that the inclusion of Islamic banking products in the financial systems will, along with the diversification effect, stimulate financial deepening and, therefore, improve the financial stability in the countries under investigation in particular, and all countries with significant Muslim population in general.

Originality/value
This study empirically assesses the contribution of Islamic banking presence on the economic growth with a focus on Southeast Asia, as this region encompasses the most developed and experienced institutions in the field of Islamic finance. Error correction-based models such as PMG, MG and DFE lend itself to the analysis of the panel data. This study also uses the instrument-based 2SLS to cope with the endogeneity problem between the real and financial sectors.
Comparison of ethical and conventional portfolios with second-order stochastic dominance efficiency test
Authors: Tas Oktay , Tokmakcioglu Kaya , Ugurlu Umut , Isiker Murat 
Published: December 2016

Purpose
This paper aims to compare two groups of stocks to analyze the efficiency of an ethical portfolio in comparison with a conventional portfolio.

Design/methodology/approach
Efficiency test by second-order stochastic dominance (SSD) approach is applied on two groups, which consist of 12 stocks. Ethical portfolio is chosen from the stocks complying with the participation banking rules. Conventional portfolio is selected from Borsa Istanbul (BIST) with choosing the corresponding stocks for each ethical stock according to the sector and market capitalization. All the stocks of both groups are pairwise SSD compared.

Findings
Both groups of 12 stocks are inefficient portfolios; however, a group of 7 stocks constitute an efficient ethical portfolio with the total weight of 50.82 per cent among the set of 12 ethical stocks. On the other hand, a group of 6 stocks constitute an efficient conventional portfolio, with the total weight of 45.16 per cent among the set of 12 conventional stocks. By pairwise SSD comparison of corresponding stocks from both groups, despite none of the conventional stocks dominate ethical stocks, four ethical stocks dominated the conventional ones.

Originality/value
Back-testing and comparison with benchmark BIST 100 Index have been done for the selected portfolios. According to back-testing results, groups of SSD efficient stocks outperformed the groups, from which they were selected. Furthermore, both SSD efficient portfolios have higher returns than benchmark index, BIST 100.
On the limits of trust
Authors: Tade Oludayo , Adeniyi Oluwatosin 
Published: December 2016

PurposeThis paper aims to investigate automated teller machine (ATM) fraud in southwest Nigeria, as extant studies have not examined the unintended consequences of ATM subscription particularly the effect of the identity of fraudsters and the strategies for defrauding.Design/methodology/approachUsing sequential exploratory strand of mixed method, data were collected from both ATM users and victims of ATM fraud using multi-stage sampling procedure. This involved purposive selection of Lagos and Oyo states.FindingsResults showed that fraudsters were typically lovers, friends, relatives and sometimes children of victims. Strategies for defrauding included card cloning, swapping of cards and physical attacks at ATM galleries.Research limitations/implicationsBecause of the size of the sample which is small, the research results may lack generalizability. More expansive works are needed across Nigeria in this regard.Practical implicationsThe paper includes implications for policy initiative concerning the deployment and use of payment systems such as ATM in Nigeria.Social implicationsThe paper reveals the limits of trust in cashless policy. It raises salient policy issues concerning the need for the governance of trust to engender adoption.Originality/valueThe paper characterizes fraudsters and their strategies for defrauding.
Auditors’ experience with corporate psychopaths
Authors: Klarskov Jeppesen Kim , Leder Christina 
Published: December 2016

PurposeThe purpose of this paper is to analyse auditors’ experience with corporate psychopaths in their client management.Design/methodology/approachThe research was conducted as a survey among Danish state-authorized auditors, to which 179 auditors responded, representing 9 per cent of the total population.FindingsOf the participating auditors, 69 per cent had experienced corporate psychopaths in their client management and 70 per cent of these had experienced more than one case. In addition, 43 per cent of the auditors who had experienced psychopathic managers reported that they had committed fraud. The vast majority of cases were detected in the execution and completion phases of the audit and resulted in increased professional scepticism, the use of more experienced auditors and the requirement for more and better audit evidence.Research limitations/implicationsThe findings confirm that corporate psychopaths actually exist and are a phenomenon worthy of research attention in areas such as accounting, auditing, internal control, fraud investigation, performance management and human resource management.Practical implicationsAs auditors are likely to come across corporate psychopaths from time to time in their careers, awareness of this type of risk needs to be increased and better integrated into the risk assessment in audit planning. Auditing standards relating to fraud also need to be updated according to the latest developments in fraud theory.Originality/valueThis is the first research to address auditors’ experience with corporate psychopaths. It adds value by confirming the relevance of the topic for practice and research.

A dedicated place for volume fraud within the current UK economic crime agenda?
Authors: King Julian , Doig Alan 
Published: December 2016

Purpose
The purpose of this study is to explore how a large UK police force – Greater Manchester Police (GMP) – sought during a period of continuing budget reductions to take a cost-effective approach to certain types of fraud through the establishment of a central Volume Fraud Team (VFT), which in turn would also have wider operational resource benefits across the force. It then explores the decision to merge that team with its existing serious and complex fraud team.

Design/methodology/approach
The research was undertaken over a period of two years by interview and desk review to explain the internal processes which underpinned the approach and the initial outcomes. It discusses why the approach was short lived as a consequence of other factors.

Findings
The paper sets out briefly the context of changes to the policing of fraud since 1979 and describes the GMP decision-making processes that established a centralised response to volume fraud and major (serious and complex) fraud. The paper assesses the available data on the approach and whether the changes facilitated a more effective means of addressing fraud and other internal policing priorities. It then discusses the decision in 2014 to merge the staff resources for volume and major frauds in response to identified policy trends in fraud investigations and changes in fraud reporting.

Research limitations/implications
The single case study is limited in terms of focus and in applicability to the wider law enforcement response to fraud.

Practical implications
The research discusses practitioner issues arising from the complexities of balancing resources and priorities against changing trends and patterns of criminal activity in a specific area of policing.

Originality/value
The research is an original study into the internal and external change agendas, and there are, therefore, wider lessons for the policing of fraud in the UK.
Identity theft reports of adolescents
Authors: Marcum Catherine D. , Higgins George E. , Mackinnon Alexandria 
Published: December 2016

Purpose
The purpose of this paper was to explore the identity theft victimization experiences of high school students, as well as the predictors of it being reported to school counselors.

Design/methodology/approach
In July and August 2014, an online survey was sent to every registered member of the American School Counselor’s Association (ASCA). School counselors were questioned about their experiences in regarding online victimization of their students.

Findings
Results of this analysis revealed extremely interesting predictors of school counselor demographics related to the number of reports filed by students.

Research limitations/implications
There was a small response rate because the survey was sent to all registered members of the ASCA, instead of a specific targeted group (which would have been more appropriate).

Practical implications
The results indicate a need for further resources and training dedicated to school counselors to manage identity theft victimization of students.

Originality/value
As far as the authors are aware, no other study of this kind has previously been performed. In addition, there is little known about identity theft victimization of adolescents.
Fraud detection suicide: the dark side of white-collar crime
Authors: Brody Richard G. , Perri Frank S. 
Published: December 2016

PurposeThe purpose of this paper is to explore the issue of suicide, a violent act against one’s self, as it relates to white- and red-collar crimes. White-collar crime can be described as nonviolent crime committed for financial gain. Red-collar crime describes a situation where a white-collar criminal commits an act of violence, often murder, to silence someone who is in a position to report a fraud they have perpetrated. Previous research has not addressed the issue of suicide, as it relates to white- and red-collar crime.Design/methodology/approachThe analysis is conceptual, focusing on the historical underpinnings of white- and red-collar crime and reviewing the evolution of white-collar criminals. Sources of information consisted of published news media, scholarly articles and articles retrieved from the web.FindingsA suicide may be linked, directly or indirectly, to a financial crime. Law enforcement must be careful not to jump to conclusions, as there is a possibility that a staged suicide has occurred.Originality/valueLaw enforcement individuals may want to consider an additional motive when investigating a suicide, especially when the victim has some type of connection to a known fraud. This type of connection may not be readily apparent and may require a new approach on the part of a law enforcement investigation.
