An evaluation of a frontline led quality improvement initiative
Authors: Flynn Rachel , Hartfield Dawn 
Published: October 2016

Purpose
The Edmonton Zone, one of five Zones in Alberta Health Services (the health system in the province of Alberta, Canada), established a quality management framework (QMF) as a means to improve the delivery of high quality health care in the spring of 2014. The purpose of this research study was to understand the factors that facilitated or hindered the implementation of a quality improvement (QI) initiative for hand hygiene led by a newly formed frontline unit quality council (UQC), a part of the QMF, based out of the pediatric intensive care unit (PICU) at the Stollery Children’s Hospital in the Edmonton Zone. This research will provide an understanding of the newly established QMF in the Edmonton Zone and the factors needed to foster the ongoing development of frontline UQC that do improvement work as part of their daily routine.

Design/methodology/approach
Using a qualitative case study research design data were collected using semi-structured open-ended interviews with six key stakeholders (one registered nurse, one physician, one patient case manager, medical director for QI, clinical QI consultant and director of clinical QI) involved in UQC at the PICU.

Findings
Individual, unit and organizational level factors were identified as influencing the function of the UQC. Leadership and work culture were the key facilitating factors to success and lack of QI training and personnel/dedicated time were perceived barriers to completing the QI initiative.

Originality/value
The findings from this research illustrate that frontline UQC are able to impact positive sustained change early in their establishment as part of a larger QMF. It is important, however, for the system to foster ongoing development of capacity and capability of these frontline UQC to ensure sustained success of the larger systems change.
Growth options, dividend payout ratios and stock returns
Authors: Li George 
Published: October 2016

Purpose
This paper aims to examine the impact of the dividend payout ratio on future stock returns and momentum strategies.

Design/methodology/approach
The author uses the portfolio sorting approach used in the momentum literature to examine this impact.

Findings
First, the author shows that the returns for the winner stocks tend to be the largest if no dividends are paid and then decrease with the dividend payout ratio; the returns for the loser stocks tend to have an inverted U-shaped relationship with the dividend payout ratio, but the zero-dividend loser stocks have the smallest return; and the returns for the stocks between the winners and the losers tend to remain similar, regardless of the dividend payout ratio. Second, the author shows that momentum profit is the largest for the stocks that do not make dividend payment but appear similar for the stocks that pay dividends. The author's empirical findings imply that stock price momentum is a function of the dividend payout ratio, growth stock momentum tends to be much stronger than value stock momentum and no-dividend stock momentum beats dividend stock momentum. In fact, when the dividend payout ratio is considered, momentum profit can be improved by up to 63 per cent.

Originality/value
This paper is the first one to examine the impact of dividend payout ratios on future stock returns and momentum profit, and it obtained many interesting empirical results. In addition, unlike most studies in the momentum literature that use behavioral theory to explain empirical findings, this paper uses the growth option idea to present a rational explanation for the empirical results in this paper.
A review of angel investing research: analysis of data and returns in the US and abroad
Authors: McDonald Michael B. , DeGennaro Ramon P. 
Published: October 2016

PurposeThe purpose of this paper is to examine the literature on angel investors. Research on angel investors is sparse because data are sparse. Most comprehensive studies of angel investors have focused on the USA and UK. In these studies, definitions of angel investors and estimates of returns on angel investments vary dramatically. What can one make of this wide range of reported returns?Design/methodology/approachThe authors examine the literature and find that the calculations of reported results are vague.FindingsMost researchers do not explicitly report if their estimates are equal-weighted or value-weighted, nor do they say whether the results are weighted by the duration of the investment. The authors show that the unit of analysis – investment, project or angel – affects interpretations.Practical implicationsLimitations on the comparability between various studies of angel investing returns leave the current literature incomplete. They also offer opportunities for future study in the area.Originality/valueThe authors are the first to examine the angel investing literature in a comprehensive fashion, comparing between various returns found across all major studies of the subject done to date.
The effects of securitized asset portfolio specialization on bank holding company’s return, and risk
Authors: Tah Kenneth A. , Martinez Oscar 
Published: October 2016

Purpose
The purpose of this paper is to examine the effect of specialization of the securitized assets portfolio on banks’ performance and securitization risk. In doing so, the paper addresses two important issues. First, whether the efficient risk–return trade-off for securitized asset portfolios is consistent with the principles of diversification. Second, whether the relationship between bank-level returns and securitized assets portfolio specialization is non-linear in securitization risk.

Design/methodology/approach
This paper used the fixed-effects panel regression model on US bank holding company data for the period 2001:Q2 to 2014:Q1.

Findings
The results show that securitized assets portfolio specialization increases returns and also reduces securitization default risk; banks’ return and securitized assets specialization are dependent in a non-linear manner on banks’ securitization risk. Additionally, it was also found that lower bank performance leads to higher securitization risk.

Originality/value
This paper is of value by demonstrating that diversification (specialization) of securitized assets portfolio would achieve better bank performance in low-risk (high-risk) scenarios.
How technology can fuel the diversity challenge
Authors: Hipps Charles 
Published: October 2016

Purpose
The purpose of the feature was to examine how technology can help the recruitment industry in overcoming some, if not all, diversity challenges.

Design/methodology/approach
It is a byline paper written by Charles Hipps, CEO of WCN, who touches upon personal knowledge, organisational information and previous industry findings to create the most well-rounded paper possible.

Findings
The paper concludes that for companies who view the diversity challenge as an opportunity, the use of modern technology to enable staff and the analysis of all of the data available has real potential to improve business performance. The challenge is on for organisations to scrutinise the technological software solutions available to them and pull them together to create an overall picture that looks right for itself and its candidates. After all, the war for diverse talent is on, and recruitment and processes of human resources must keep up with the challenge to win hearts and minds – and ultimately business prosperity.

Originality/value
Within the paper, there are personal findings, research conducted by others (which is added as an endnote) and general individual views from a thought-leader. Whenever statistics were used that do not belong to WCN, it was fully stated and attributed accordingly.
The evolving diversity agenda
Authors: Wilson Burns Erin , Ulrich Dave 
Published: October 2016

Purpose
In this paper, the authors share answers to the following questions based on data collected from 183 global companies in the most recent round of Aon Hewitt Top Companies for Leaders®: Does diversity and inclusion matter? What is diversity? What practices build more diverse workforces and more inclusive cultures?

Design/methodology/approach
Much of the research cited in this paper comes from the Aon-Hewitt Top Companies for Leaders® data set. In the latest round of data collection, completed in late 2014, 183 companies participated from around the world. Each completed a detailed online questionnaire of leadership practices. From those submissions, finalists were identified and hundreds of interviews were conducted with senior line and executives of human resources. A panel of expert judges determined the global and regional winners based on their responses to the survey questionnaire and interviews, as well as financial and other publicly available information.

Findings
Whether it is a causal relationship or merely a correlated finding, companies that have diverse, inclusive talent strategies appear to out-perform their peers on both talent and financial outcomes.

Practical implications
This paper highlights the differences between top companies in managing diversity compared to other companies in the research data. It also highlights some best practice methods to build diversity.

Originality/value
This paper documents the evolution of the definitions of diversity and considers diversity as a means to business ends rather than an end in itself.
A machine vision based autonomous navigation system for Lunar rover: the model and key technique
Authors: Li Hui , Zhong Cheng 
Published: October 2016

Purpose
This study aims to find a feasible precise navigation model for the planed Lunar rover. Autonomous navigation is one of the most important missions in the Chinese Lunar exploration project. Machine vision is expected to be a promising option for this mission because of the dramatic development of an image processing technique. However, existing attempts are often subject to low accuracy and errors accumulation.

Design/methodology/approach
In this paper, a novel autonomous navigation model was developed, based on the rigid geometric and photogrammetric theory, including stereo perception, relative positioning and absolute adjustment. The first step was planned to detect accurate three-dimensional (3D) surroundings around the rover by matching stereo-paired images; the second was used to decide the local location and orientation changes of the rover by matching adjacent images; and the third was adopted to find the rover’s location in the whole scene by matching ground image with satellite image. Among them, the SURF algorithm that had been commonly believed as the best algorithm for matching images was adopted to find matched images.

Findings
Experiments indicated that the accurate 3D scene, relative positioning and absolute adjustment were easily generated and illustrated with the matching results. More importantly, the proposed algorithm is able to match images with great differences in illumination, scale and observation angle. All experiments and findings in this study proved that the proposed method could be an alternative navigation model for the planed Lunar rover.

Originality/value
With the matching results, an accurate 3D scene, relative positioning and absolute adjustment of rover can be easily generated. The whole test proves that the proposed method could be a feasible navigation model for the planed Lunar rover.
Development of a combined magnetic encoder
Authors: Feng Tong , Hao Shuanghui , Hao Minghui , Wang Jianli 
Published: October 2016

Purpose
As a type of angular displacement sensor, the Hall-effect magnetic encoder incorporates many advantages. While compared with the photoelectric encoder, the magnetic encoder nevertheless has lower precision and lower resolution. So, the purpose of this essay is to find a way to increase the precision and resolution of the magnetic encoder.

Design/methodology/approach
By combining a single-pole magnetic encoder and a multi-pole AlNiCo magnet, the precision and resolution of this combined magnetic encoder are increased without increasing its volume or complicating its structure. A special algorithm system is developed to ensure faithful encoding and decoding.

Findings
Tests show that the combined magnetic encoder, with a diameter of 67.12 mm (including shaft) and thickness of 6.9 mm, has a precision of ±6′, compared with a 15-bit photoelectric encoder and a static resolution of ±0.6′.

Originality/value
This new kind of magnetic encoder could be used in specialized fields which need high-precision servo-control systems that are small, have ultra-low-speed and high-speed ratios and are non-oil-polluting or shock-resistant.
Communities of practice: A means to support occupational therapists’ continuing professional development. A literature review
Authors: Barry Margot , Kuijer‐Siebelink Wietske , Nieuwenhuis Loek , Scherpbier‐de Haan Nynke 
Published: October 2016

BackgroundThis literature review investigates what research reports about the contribution that communities of practice (CoPs) can make in the continuing professional development (CPD) of qualified occupational therapists.MethodsAcademic databases (CINAHL, MEDLINE and ERIC) were searched and articles were included based on pre‐determined criteria. Five articles were included in the review.ResultsThe CoPs in the reviewed articles provided opportunities for knowledge sharing, knowledge translation, reflection on action and learning through boundary crossing. The presence of professionals with diverse perspectives was an important ingredient that facilitated CPD.ConclusionResearch into the use of CoPs in occupational therapy is sparse. CoPs could provide a CPD forum for occupational therapists whether online or face to face. Practitioners are encouraged to participate in CoPs. Further research into the use of CoPs is recommended.

Published: October 2016

Khoa, a heat‐concentrated milk product, is used as a base material for the manufacture of many popular sweets. The comparison was made between various chemical compositions and characteristics of the khoa prepared from the camel milk with that prepared from the cow and the buffalo milk samples. The khoa prepared from the camel milk had the higher moisture, ash, acidity, soluble nitrogen, free fatty acids and peroxide value, but lower in fat, protein and lactose contents than that prepared from the cow and buffalo milk samples. There was no significant (P > 0.05) difference in 5‐hydroxymethyl furfural between khoa samples prepared from the three milks.

Published: October 2016

ObjectiveTo update amenable mortality in 32 OECD countries at 2013 (or last available year), to describe the time trends during 2000–2013, and to evaluate the association of these trends with various geographic areas.Data SourcesSecondary data from 32 countries during 2000–2013, gathered from the World Health Organization Mortality Database.Study DesignTime trend analysis.Data CollectionUsing Nolte and McKee's list, age‐standardized amenable mortality rates (SDRs) were calculated as the annual number of deaths over the population aged 0–74 years per 100,000 inhabitants. We performed a mixed‐effects polynomial regression analysis on the annual SDRs to determine whether specific geographic areas were associated with different SDR trajectories over time.Principal FindingsThe OECD average annual decrease was 3.6/100,000 (p < .001), but slowed over time (coefficient for the quadratic term = 0.11, p < .001). Eastern and Atlantic European countries had the steepest decline (−6.1 and −4.7, respectively), while Latin American countries had the lowest slope (−1.7). The OECD average annual decline during the 14‐year period was −0.5 (p < .001) for cancers and −2.5 (p < .001) for cardiovascular diseases, with significant differences among countries.ConclusionDeclining trend of amenable SDRs was continuing to 2013 but with steepness change compared with previous periods and with a slowdown.

Published: October 2016

AbstractIntroductionThis study was performed to evaluate the diagnostic performance of multi‐slice CT angiography combined with enterography in determining the cause and location of obstruction as well as intestinal ischaemia in patients with small bowel obstruction (SBO).MethodsThis study retrospectively summarized the image data of 57 SBO patients who received both multi‐slice CT angiography and enterography examination between December 2012 and May 2013. The CT diagnoses of SBO and intestinal ischaemia were correlated with the findings at surgery or digital subtraction angiography, which were set as standard references.ResultsMulti‐slice CT angiography and enterography indicated that the cause of SBO in three patients was misjudged, suggesting a diagnostic accuracy of 94.7%. In one patient the level of obstruction was incorrect, demonstrating a diagnostic accuracy of 98.2%. Based on the results of the receiver operating characteristic (ROC) curve analysis, the diagnostic criterion for ischaemic SBO was at least two of the four CT signs (circumferential bowel wall thickening, reduced enhancement of the intestinal wall, mesenteric oedema and mesenteric vascular engorgement). The criterion yielded a sensitivity of 94.4%, a specificity of 92.3%, a positive predicted value of 85.0% and a negative predicted value of 97.3%, and the area under curve (AUC) was 0.92 (95% CI, 0.85–0.99).ConclusionMulti‐slice CT angiography and enterography have high diagnostic value in identifying the cause and site of SBO. In addition, the suggested diagnostic criterion using CT signs is helpful for diagnosing intestinal ischaemia in SBO patients.

Authors: Ryu Seung Wook , Ho Ken , O'Toole Sandra A , Green Alison , Kim Hae Won 
Published: October 2016

SummaryMale breast cancers (MBC) are rare, accounting for <1% of all breast cancers. The use of magnetic resonance imaging (MRI) for male breast cancer is not generally indicated. We present an unusual case where conventional imaging for a suspected MBC was equivocal and MRI was required to assist in diagnosis.
‘Compromise position’ image alignment to accommodate independent motion of multiple clinical target volumes during radiotherapy: A high risk prostate cancer example
Authors: Rosewall Tara , Yan Jing , Alasti Hamideh , Cerase Carla , Bayley Andrew 
Published: October 2016

AbstractIntroductionInclusion of multiple independently moving clinical target volumes (CTVs) in the irradiated volume causes an image guidance conundrum. The purpose of this research was to use high risk prostate cancer as a clinical example to evaluate a ‘compromise’ image alignment strategy.MethodsThe daily pre‐treatment orthogonal EPI for 14 consecutive patients were included in this analysis. Image matching was performed by aligning to the prostate only, the bony pelvis only and using the ‘compromise’ strategy. Residual CTV surrogate displacements were quantified for each of the alignment strategies.ResultsAnalysis of the 388 daily fractions indicated surrogate displacements were well‐correlated in all directions (r2 = 0.95 (LR), 0.67 (AP) and 0.59 (SI). Differences between the surrogates displacements (95% range) were −0.4 to 1.8 mm (LR), −1.2 to 5.2 mm (SI) and −1.2 to 5.2 mm (AP). The distribution of the residual displacements was significantly smaller using the ‘compromise’ strategy, compared to the other strategies (p 0.005). The ‘compromise’ strategy ensured the CTV was encompassed by the PTV in all fractions, compared to 47 PTV violations when aligned to prostate only.ConclusionsThis study demonstrated the feasibility of a compromise position image guidance strategy to accommodate simultaneous displacements of two independently moving CTVs. Application of this strategy was facilitated by correlation between the CTV displacements and resulted in no geometric excursions of the CTVs beyond standard sized PTVs. This simple image guidance strategy may also be applicable to other disease sites that concurrently irradiate multiple CTVs, such as head and neck, lung and cervix cancer.

Published: October 2016

BackgroundProblem substance use often begins in adolescence. This vulnerability likely stems, at least partially, from relatively rapid increases in sensation seeking occurring in early to mid‐adolescence and more gradual improvements in impulse control occurring through later adolescence. Better understanding how these processes develop in high‐risk youth may lead to enhanced substance use disorder treatment and prevention strategies.MethodsWe characterized trajectories of self‐reported impulsivity and sensation seeking in 305 FH+ youths who at minimum had a father with a history of alcohol or other drug use disorders and 81 youths with no family histories of substance use disorders (FH−). Assessments started at ages 10 to 12 and continued at 6‐month intervals for up to 42 months. In addition, a subset of 58 FH+ youths who began alcohol or other drug use before age 15 (FH+ Users) were compared to 58 FH+ propensity‐matched adolescents who did not initiate substance use before age 15 (FH+ Non‐Users).ResultsCompared to FH− youths at preadolescence, FH+ youths reported higher general impulsivity and higher impulsivity related to poor planning and attention. Over time, there were no differential effects of FH status on changes in impulsivity or sensation seeking across adolescence. FH+ Users had smaller decreases in general impulsivity and impulsivity related to restlessness and fidgeting across adolescence than FH+ Non‐Users. FH+ Users also had greater increases in sensation seeking across adolescence than FH+ Non‐Users.ConclusionsIncreased impulsivity in FH+ youths may make them less able to regulate sensation seeking drives that peak in adolescence, which may contribute to their high risk for developing substance use disorders. Additionally, FH+ adolescents who initiate early use may be at increased risk in part due to increased impulsivity coupled with greater increases in sensation seeking.
