Managing Customer Expectations and Priorities in Service Systems
Authors: Yu Qiuping , Allon Gad , Bassamboo Achal , Iravani Seyed 
Published: August 2017

We study how to use delay announcements to manage customer expectations while allowing a firm to prioritize among customers with different sensitivities to time and value. We examine this problem by developing a framework that characterizes the strategic interaction between the firm and heterogeneous customers. When the firm has information about the state of the system, yet lacks information on customer types, delay announcements play a dual role: they inform customers about the state of the system, while they also have the potential to elicit information on customer types based on their response to the announcements. The tension between these two goals has implications for the type of information that can be shared credibly. To explore the value of the information on customer types, we also study a model where the firm can observe customer types. We show that having information on the customer type may improve or hurt the credibility of the firm. While the creation of credibility increases the firm’s profit, the loss of credibility does not necessarily hurt its profit. This paper was accepted by Noah Gans, stochastic models and simulation.

Published: August 2017

Background: Predictive genetic testing is important for risk stratification in inherited cardiac conditions, yet may cause psychological distress. The aim of this study was to determine the healthcare needs of young adults undergoing predictive testing for inherited cardiomyopathies. Method: In this qualitative study, 11 young adults (aged 16–25 years) were interviewed; data was analysed inductively using thematic analysis. Results: Interviewees had a reasonable understanding of inheritance but there was often confusion between cardiac imaging and genetic testing results. Young adults who described a traumatic experience following a family member's diagnosis showed more anxiety than those who had known about their risk since birth. Participants expressed anxiety regarding their future health, reproductive plans and career choices. Conclusion: Confusion, reliance on parents and limited communication with others may be especially applicable to young adults having predictive testing. Implications: Tailored counselling is needed, with appropriate transitional arrangements to enable young adults to assume responsibility for their health care.
Involvement in midwifery education: Experiences from a service user and carer partnership
Authors: Warren Angela , Hughes Mel , Fry Jane , Cescutti-Butler Luisa 
Published: August 2017

This article provides a critical reflection on the experiences of the Bournemouth University Public Involvement in Education and Research (PIER) partnership in developing approaches to involving service users and user groups within midwifery programmes of education; an NMC requirement since 2009. Specific models and activities are explored, including using social media to consult with expectant and new parents; organising direct conversations between women, their families, academics and students to explore experiences such as grief and loss and the use of support networks during pregnancy; and developing digital resources to create real, in depth and meaningful case studies. Three key benefits to having meaningful and well supported involvement are identified: emotional impact and the opportunity to develop insight and resilience; knowledge impact and the opportunity to better understand the application of theory; and practical impact, which can lead to tangible changes to students' subsequent practice.

Published: August 2017

Aims After the initial correction of congenital talipes equinovarus (CTEV) using the Ponseti method, a subsequent dynamic deformity is often managed by transfer of the tendon of tibialis anterior (TATT) to the lateral cuneiform. Many surgeons believe the lateral cuneiform should be ossified before surgery is undertaken. This study quantifies the ossification process of the lateral cuneiform in children with CTEV between one and three years of age. Patients and Methods The length, width and height of the lateral cuneiform were measured in 43 consecutive patients with unilateral CTEV who had been treated using the Ponseti method. Measurements were taken by two independent observers on standardised anteroposterior and lateral radiographs of both feet taken at one, two and three years of age. Results All dimensions of the lateral cuneiform on the affected side increased annually but remained smaller than the corresponding dimensions of the unaffected foot (p < 0.01). The lateral cuneiform resembled a 9 mm cube at two years and an 11 mm cube at three years. Conclusion At one and two years, the ossification centre of the lateral cuneiform may not be large enough to accommodate a drill hole for tendon transfer. However, by three years, it has undergone sufficient ossification to do so. Cite this article: Bone Joint J 2017;99-B:1109–14.
Factors affecting the rate of surgical site infection in patients after hemiarthroplasty of the hip following a fracture of the neck of the femur

Published: August 2017

Aims Surgical site infection can be a devastating complication of hemiarthroplasty of the hip, when performed in elderly patients with a displaced fracture of the femoral neck. It results in a prolonged stay in hospital, a poor outcome and increased costs. Many studies have identified risk and prognostic factors for deep infection. However, most have combined the rates of infection following total hip arthroplasty and internal fixation as well as hemiarthroplasty, despite the fact that they are different entities. The aim of this study was to clarify the risk and prognostic factors causing deep infection after hemiarthroplasty alone. Patients and Methods Data were extracted from a prospective hip fracture database and completed by retrospective review of the hospital records. A total of 916 patients undergoing a hemiarthroplasty in two level II trauma teaching hospitals between 01 January 2011 and 01 May 2016 were included. We analysed the potential peri-operative risk factors with univariable and multivariable logistic regression analysis. Results A total of 92 patients (10%) had a surgical site infection, and 44 (4.9%) developed a deep infection. After univariable analyses, the multivariable model showed that the level of experience of the surgeon measured by the number of hemiarthroplasties performed per year was a significant prognostic factor (odds ratio (OR) 0.93, p = 0.042) for the development of an infection. Secondly, the development of a haematoma (OR 9.6, p < 0.001), a re-operation (OR 4.7, p = 0.004) and an operating time of < 45 mins (OR 5.1, p = 0.002) or > 90 mins (OR 2.7, p = 0.034) were also significant factors. Conclusion There was a significant association between the experience of the surgeon and the rate of deep infection. Secondly, a haematoma, a re-operation and both shorter and longer operating times were associated with an increased risk of deep infection after hemiarthroplasty. No association was found between deep infection and the anatomical approach, the time when surgery was undertaken and the use of a drain. Cite this article: Bone Joint J 2017;99-B:1088–94.
The validity and reproducibility of cross table radiographs compared with CT scans for the measurement of anteversion of the acetabular component after total hip arthroplasty

Published: August 2017

Aims The aim of this study was to assess the reproducibility and validity of cross table radiographs for measuring the anteversion of the acetabular component after total hip arthroplasty (THA) and to compare it with measurements using CT scans. Patients and Methods A total of 29 patients who underwent THA between June 2010 and January 2016 were included. There were 17 men and 12 women. Their mean age was 43 years (26 to 65). Seven patients underwent a bilateral procedure. Thus, 36 THAs were included in the study. Lateral radiographs and CT scans were obtained post-operatively and radiographs repeated three weeks later. The anteversion of the acetabular component was measured using the method described by Woo and Morrey and the ischiolateral method described by Pulos et al and these were compared with the results obtained from CT scans. Results The mean anteversion was 18.35° (3° to 38°) using Woo and Morrey’s method, 51.45° (30° to 85°) using the ischiolateral method and 21.22° (2° to 48°) using CT scans. The Pearson correlation coefficient was 0.754 for Woo and Morrey’s method and 0.925 for the ischiolateral method. There was a linear correlation between the measurements using the ischiolateral method and those using CT scans. We derived a simple linear equation between the value of the CT scan and that of ischiolateral method to deduce the CT scan value from that of ischiolateral method and vice versa. Conclusion The anteversion of the acetabular component measured using both plain radiographic methods was consistently valid with good interobserver reproducibility, but the ischiolateral method which is independent of pelvic tilt was more accurate. As CT is costly, associated with a high dose of radiation and not readily available, the ischiolateral method can be used for assessing the anteversion of the acetabular component.

Published: August 2017

Aims It is well established that there is a strong association between Perthes’ disease and worsening socioeconomic deprivation. It has been suggested that the primary determinant driving this association is exposure to tobacco smoke. This study aimed to examine this hypothesis. Patients and Methods A hospital case-control study (n = 149/146) examined the association between tobacco smoke exposure and Perthes’ disease, adjusting for area-level socioeconomic deprivation. Tobacco smoke exposure was assessed by parental questionnaire of smoking habits during pregnancy, and by quantitative assay of current exposure using the urinary cotinine-creatinine ratio, which is a widely used and validated measure of tobacco smoke exposure. Results The odds of Perthes’ disease significantly increased with reported in utero exposure after adjustment for socioeconomic deprivation (maternal smoking odds ratio (OR) 2.06, 95% confidence interval (CI) 1.17 to 3.63; paternal smoking OR 2.09, 95% CI 1.26 to 3.46). The cotinine-creatinine ratio was significantly greater in cases, OR 1.63 (95% CI 1.09 to 2.43), suggesting a greater ‘dose’ of current tobacco exposure. Conclusion An association exists between tobacco smoke exposure and Perthes’ disease but we remain unable to disentangle the association with socioeconomic deprivation.

Published: August 2017

AimsCeramic-on-ceramic (CoC) bearings in total hip arthroplasty (THA) are commonly used, but concerns exist regarding ceramic fracture. This study aims to report the risk of revision for fracture of modern CoC bearings and identify factors that might influence this risk, using data from the National Joint Registry (NJR) for England, Wales, Northern Ireland and the Isle of Man.Patients and MethodsWe analysed data on 223 362 bearings from 111 681 primary CoC THAs and 182 linked revisions for bearing fracture recorded in the NJR. We used implant codes to identify ceramic bearing composition and generated Kaplan-Meier estimates for implant survivorship. Logistic regression analyses were performed for implant size and patient specific variables to determine any associated risks for revision.ResultsA total of 222 852 bearings (99.8%) were CeramTec Biolox products. Revisions for fracture were linked to seven of 79 442 (0.009%) Biolox Delta heads, 38 of 31 982 (0.119%) Biolox Forte heads, 101 of 80 170 (0.126%) Biolox Delta liners and 35 of 31 258 (0.112%) Biolox Forte liners. Regression analysis of implant size revealed smaller heads had significantly higher odds of fracture (chi-squared 68.0, p < 0.001). The highest fracture risk was observed in the 28 mm Biolox Forte subgroup (0.382%). There were no fractures in the 40 mm head group for either ceramic type. Liner thickness was not predictive of fracture (p = 0.67). Body mass index (BMI) was independently associated with revision for both head fractures (odds ratio (OR) 1.09 per unit increase, p = 0.031) and liner fractures (OR 1.06 per unit increase, p = 0.006).ConclusionsWe report the largest independent study of CoC bearing fractures to date. The risk of revision for CoC bearing fracture is very low but previous studies have underestimated this risk. There is good evidence that the latest generation of ceramic has greatly reduced the odds of head fracture but not of liner fracture. Small head size and high patient BMI are associated with an increased risk of ceramic bearing fracture. Cite this article: Bone Joint J 2017;99-B:1012–19.

Published: August 2017

The writings that discuss the practice of forced marriage signifies that the forced marriage is still massively implemented in the community. The phenomenon of forced marriage is right using religious arguments. Forced marriages in fiqh known as ijbār rights. Forced marriage can be a manifestation of the right ijba̅r if the requirements are met in determining ijba̅r, and if it is not in accordance with these concepts then a forced marriage positioned as ikrah. This paper specifically discusses the forced marriage in perspective of Kiai Krapyak. The view of Kiai Krapyak toward forced marriage with opposing views literally. But essentially the view of Kiai Krapyak tend to be similar. They agree that forced marriages should as much as possible to be avoided, though, in the law of Islam , the practice of forced marriages are a valid contract. Islamic law does not condone a forced marriage which connotes as ikrah, although the majority of schools of fiqh agree for the ijbār rights. The majority of schools of fiqh agree that they have their rights with a different perspective of the school of one sect to another. Positive law mentions the consent of both couples as a necessity, then automatically there is no compromise on the permissibility of execution of forced marriage.[Tulisan-tulisan yang membahas tentang kawin paksa menandakan bahwa praktek atau pelaksanaan perkawinan paksa masih masif di kalangan masyarakat. Fenomena kawin paksa menjadi ritus dengan menggunakan hujah agama. Kawin paksa dalam fiqh dikenal dengan istilah hak ijbār. Kawin paksa bisa jadi manifestasi dari hak ijba̅r apabila terpenuhi syarat-syarat dalam menentukan ijba̅r, dan apabila tidak sesuai dengan konsep tersebut maka kawin paksa diposisikan sebagai ikrah. Tulisan ini khusus membahas tentang kawin paksa dalam perspektif Kiai Krapyak. Pandangan Kiai-kiai Krapyak terhadap kawin paksa mempunyai pandangan yang berbeda secara literal. Akan tetapi secara esensial pandangan para Kiai Krapyak cenderung sama. Mereka sepakat bahwa kawin paksa sebisa mungkin untuk dihindari, meskipun dalam prakteknya kawin paksa merupakan akad yang sah. Hukum Islam tidak membenarkan adanya kawin paksa yang berkonotasi ikrah, kendatipun mayoritas mazhab fiqh sepakat adanya hak ijbār. Mayoritas mazhab fiqh sepakat adanya hak tersebut dengan perspektif yang berbeda antara mazhab satu dengan mazhab yang lain. Hukum positif menyebutkan persetujuan kedua pasangan sebagai suatu keharusan, maka secara otomatis tidak ada kompromi terhadap kebolehan pelaksanaan kawin paksa.]

Published: August 2017

Abstract
Degradation of material caused by impacts of a solid particle (erodent) suspended in a liquid is called slurry erosion and is a major problem in the hydropower and maritime industry. Slurry erosion depends on many factors, e.g. liquid and erodent velocity, size, shape, angle of impact, hardness and number of erodents, and strength of a target material. The various types of test devices have been designed to investigate an effect of mentioned parameters on material resistance. In the paper are described main types of the test apparatus showing their main advantages and disadvantages. Some results of slurry erosion resistance of few groups of materials are also presented.
A Simple Fix for a Complex Problem? Comments on Morgan Ricks, The Money Problem: Rethinking Financial Regulation
Authors: Blair Margaret M. 
Published: August 2017

Abstract
The financial crisis of 2007–2009 left scholars and policy analysts scrambling to explain what went wrong. While a variety of stories have been told, none have seemed like they could account for the magnitude of the collapse in securities values, or the devastation the collapse caused to the performance of whole economies around the globe, nor could they offer a clear path to reform. Legislation passed to reform the financial system in the U.S. is extraordinarily complex, and still very controversial. Now, however, Morgan Ricks’ new book, The Money Problem: Rethinking Financial Regulation, cuts through the complexity to offer a relatively simple but compelling explanation – the crisis was a consequence of an old-fashioned run on the “bank”, which, in this case, was the shadow banking system rather than regular banks. The solution is the same as the solution that prevented major financial crises in the U.S. from the 1930s to 2007 – government insurance of “money claims” and stricter regulation of firms that are allowed to issue money-like claims.
Unconfined laminar nanofluid flow and heat transfer around a rotating circular cylinder in the steady regime

Published: August 2017

AbstractIn this work, steady flow-field and heat transfer through a copper- water nanofluid around a rotating circular cylinder with a constant nondimensional rotation rate α varying from 0 to 5 was investigated for Reynolds numbers of 5–40. Furthermore, the range of nanoparticle volume fractions considered is 0–5%. The effect of volume fraction of nanoparticles on the fluid flow and heat transfer characteristics are carried out by using a finite-volume method based commercial computational fluid dynamics solver. The variation of the local and the average Nusselt numbers with Reynolds number, volume fractions, and rotation rate are presented for the range of conditions. The average Nusselt number is found to decrease with increasing value of the rotation rate for the fixed value of the Reynolds number and volume fraction of nanoparticles. In addition, rotation can be used as a drag reduction technique.
On wave propagation in a random micropolar generalized thermoelastic medium
Authors: Mitra Manindra , Bhattacharyya Rabindra Kumar 
Published: August 2017

AbstractThis paper endeavours to study aspects of wave propagation in a random generalized-thermal micropolar elastic medium. The smooth perturbation technique conformable to stochastic differential equations has been employed. Six different types of waves propagate in the random medium. The dispersion equations have been derived. The effects due to random variations of micropolar elastic and generalized thermal parameters have been computed. Randomness causes change of phase speed and attenuation of waves. Attenuation coefficients for high frequency waves have been computed. Second moment properties have been briefly discussed with application to wave propagation in the random micropolar elastic medium. Integrals involving correlation functions have been transformed to radial forms. A special type of generalized thermo-mechanical auto-correlation functions has been used to approximately compute effects of random variations of parameters. Uncoupled problem has been briefly outlined.
Conformity Preferences and Information Gathering Effort in Collective Decision Making
Authors: Ding Huihui 
Published: August 2017

AbstractOur study concerns a collective decision-making model for the collection of information from two voters. Both voters, who tend to make the same voting choices because of their conformity preferences, collect information about the consequences of a project and then vote on the project. We focus on an informative equilibrium in which voters vote informatively using pure strategies. This is a symmetric Nash equilibrium. Our result is interesting as it shows that nonconformist voters exert less effort from a social perspective because of a positive externality that results in the free-rider problem, while conformity preferences can help to improve the sum of the voters’ expected payoffs from the social perspective. This is because conformity preferences may alleviate the free-rider problem associated with coordination (making the same vote). Specifically, conformity preferences give special importance to the correlation between voters’ signals, even if this correlation is unrelated to the accuracy of the signals. Furthermore, we present the exact conformity preference level which helps voters to exert an optimal effort level that maximizes the sum of the voters’ expected payoffs compared to the nonconformist case. In addition, we graphically illustrate comparative statics on effort levels in informative equilibria.
