Abstract
Purpose
In this research project, electrical conductive yarns were knitted together with 100 per cent cotton yarns to create knitted fabrics that would be used as electromagnetic (EM) shielding materials. The paper aims to discuss these issues.
Design/methodology/approach
1×1 plain fabrics knitted on double-bed hand knitting machines of five and seven gauges. Several strands of the cotton yarns were used together in order to knit samples with good handling properties. The electrical conductive yarn has six plies and each ply has 29 filaments with Naño-coating of silver and having an electrical resistance of 4 Ohms per 100 mm and a count of 96 Tex. The knitted fabrics have similar texture but vary in term of specific weight, fabric density, loop length, Tex, tightness factor, thickness and electrical conductivity. These variations affected the properties of the fabrics, determining factors of a good shielding or not. A special designed Faraday cage was built to measure the EMSE of each knitted fabrics. The EM waves were sent through the signal generator at different frequencies as from 400 to 1,100 MHz and with three different power inputs of 10, 20 and 30 dBm. EMSE measurements were also carried out after the knitted samples were rotated clockwise.
Findings
Good EMSE shielding results were achieved with the knitted samples, however in this study it was found that different knitted fabrics shielded better at specific frequencies and power inputs.
Practical implications
Knitted fabrics can be used to develop comfortable garments that can be used to shield EM waves and protect the wearer.
Originality/value
The choice of using the conductive yarns is exclusive. In addition the EMSE were measured with fabrics knitted in the same structure but on different knitting machine gauge. Three different power inputs were considered and EMSE measurements were taken using frequencies as from 400 to 1,100 MHz. A new method for measuring the electrical resistance on the knitted fabrics and the method used for measuring the EMSE for each knitted fabric were considered.

Abstract
This paper investigates the international market research activities of 96 successful small and medium‐sized exporters. The research focuses upon the types of information considered most important for decision making and the various sources that these enterprises use to obtain the information. The empirical work suggests successful firms put much greater emphasis on the information required for long‐term strategic planning rather than the day to day operations of the business. The vast majority of the firms used internal sources for this information. Strong statistical evidence is presented to suggest that the firms under investigation actively use the information they collect for decision making, rather than simply paying lip service to the concept of market research. This work makes an important contribution to the literature, because it represents one of very few empirical studies which provide support for the widely held belief that collection and subsequent use of market information is an important feature of successful exporters’ behaviour.

Abstract
Purpose
Previous studies suggest that the presence of medical evidence is rare in child sexual assault (CSA) cases, and if present at all, such evidence is unlikely to identify a specific assailant. This study aims to examine the role medical evidence plays in criminal cases of CSA. Specifically, the prevalence of medical evidence in CSA cases, its impact on decisions to prosecute CSA cases, as well as its effect on conviction rates are examined.
Design/methodology/approach
A systematic literature review was conducted on the impact of medical evidence in criminal child sexual abuse (CSA) cases.
Findings
The results of the review suggest medical evidence increases the likelihood of prosecution; however the impact of medical evidence on conviction rate is equivocal.
Research limitations/implications
The implications of these findings for legal and psychological practice, government policy and future areas for academic research are discussed.
Originality/value
To the authors' knowledge, no other review has systematically examined the role of medical evidence on the prosecution and conviction of CSA cases.

Abstract
In early 2017 I was watching YouTube, and being bounced around by its algorithmic recommendations. One suggestion appearing down the side bar column of jpegs was MARROW, from Anohni’s 2016 album Hopelessness. It figures a black background and foregrounds an ageing, smiling, bejewelled woman lip-syncing to the song. She is the American artist Lorraine O’Grady. Watching it felt odd, as if something was `out of place’.
Anohni speaks through her, using ventriloquist tactics to displace her own body and O’Grady’s voice. This interested me. It was the first time I had been presented with the body of an ageing woman without knowing what she looked like in youth (unlike Madonna or Aretha Franklin for example). And it was the first time I had seen lip syncing done in such an eerie fashion. The tactic is used on other music videos for tracks taken from the album where ageing women and women of colour are centre stage.
Using the idea of a place that it is ‘out of time’, in that the music videos are set in a blank space and the lip- syncing upsets the idea of a single sutured speaking author, the chapter explores the idea of `queer temporality’ by using Judith Halberstam’s 2005 work. It suggests that the music videos are potentially transgressive in their presentation of a non-normative and fractured bodies. It uses work from ageing studies (Baars, 2012) and trans-ageing (Moglen, 2008) to suggest the transgressive potential of Anonhi’s music videos in how they position transgendered voices and ageing bodies.

Abstract
This study analyzes trends in analyst forecast properties from 1987 through 1998 in the United States and seven Pacific Rim countries: Australia, New Zealand, Taiwan, Hong Kong, Japan, South Korea, and Thailand. Analyst forecast properties in the United States have become less dispersed, more accurate, and less optimistic during the sample period. Similar trends exist in Australia and New Zealand, but not in the other sample countries. In contrast, the forecast property trends of most Asian countries are the exact opposite. For example, in Japan and Korea, forecast dispersion, forecast error, and optimism all significantly increase over the sample period. The results suggest that Asian firms do not play the U.S.‐style earnings game in which managers guide analysts toward a certain target number and then report earnings that beat the target.

Abstract
Purpose
This paper aims to explore the effects of formal police organizational structure on child sexual abuse case attrition.
Design/methodology/approach
Data from two surveys were merged for this analysis: a 1988 survey of child abuse enforcement in US police departments, and the 1987 Law Enforcement Management and Administrative Statistics (LEMAS) database produced by the Bureau of Justice Statistics. Based on the structure‐performance link that is rooted in structural contingency theory, this study examines the effects of both global and specific structural features on two case disposition ratios. Because structure is more easily malleable than other factors that may affect performance, such as environment and context, it is important to know whether certain structural arrangements produce more desirable outcomes than others.
Findings
The results indicate that the global structural variables included in this analysis play a small role in child sexual abuse case attrition. None of the variables included in the model influence the rate at which cases are designated as “founded”. The size and height of police agencies and the rate at which they designate cases as founded both influence their arrest rates for child sexual abuse cases.
Research limitations/implications
The small sample size made it difficult to estimate the models. Future research should test the findings reported here using larger samples.
Originality/value
To the author's knowledge this is the first study to compare the effects of global and specific structures on police outputs.

Abstract
Purpose
The objective of this work is to develop a model that can be used for simulation of different parameters including price, subjected to different control strategies.
Design/methodology/approach
The entire supply chain can be modelled by combining the transfer function into a closed loop system. The transfer function of each entity in the supply chain can be obtained by using the control theory tools. The model can be approximated as a linear discrete system with various operating constants, like lead time, price, order policy and supply.
Findings
The continuous replenishment ordering policy for a distribution node in a supply chain was analyzed using the z-transform. Characteristic equations of the closed loop transfer function are obtained. The bullwhip (BW) effect is analyzed. Study proves that the BW effect is in evitable if the standard heuristic ordering policy is employed with demand forecasting; also the paper analysed price supply trade-off for dynamic demand and supply. Simulation results show that BW is less in PI and simple p-only with cascade control. Robust control and PD, PID control results are not shown in this literature, and it is subject to further research.
Originality/value
Research is original, it can be applicable in today's dynamic world, due to globalization, it is necessary to have a automated machine that can handle most of supply chain decision.

Abstract
Many scholars and practitioners consider development to be as much an institutional and organizational phenomenon as it is an economic one. Among other elements, civil society is a key determinant of a country’s level of social capital. Important links appear to exist between a robust associational milieu and the effective operation of democracy. However, the role of civil society organizations in human development has only recently gained attention.
