Hydronephrosis Presenting 6 Months After Sacral Colpopexy: Case Report and Literature Review
Authors: Weber LeBrun Emily , Santamaria Estefania , Moy Louis 
Published: February 2017

Objectives
The aim of this study was to describe a case of uterovaginal prolapse managed with robotic-assisted sacral colpopexy complicated by severe right-sided hydronephrosis despite normal intraoperative cystoscopy.

Methods
A 68-year-old woman presented with a worsening vaginal bulge over the past 2 years. Tricompartment stage 2 uterovaginal prolapse, with dominant cystocele and skin erosion at the posterior fourchette from prolapse friction, was identified on physical examination, and the patient underwent pelvic reconstructive surgery, including sacral colpopexy.

Results
The patient was discharged on postoperative day 4 after being treated for a urinary tract infection. At her 6-week postoperative visit, the patient demonstrated normal vaginal support. She presented 6 months postoperatively with right-sided hydronephrosis with an almost imperceptible stricture where the right iliac vessels cross the pelvic brim, demonstrating a delayed manifestation of ureteral injury. She underwent open ureteroscopy, ureteroneocystostomy with vesicopsoas hitch, and ureteral stent placement. Ureteroscopy demonstrated a very mild narrowed caliber of the ureter just above the sacroiliac joint without overt obstruction. Follow-up intravenous pyelogram demonstrated no evidence of damage or obstruction. At nearly 1-year follow-up, the patient remained asymptomatic and had normal renal function.

Conclusion
This case demonstrates the challenges of an uncommon, but highly morbid, complication of pelvic reconstructive surgery. Even when adequate visualization of the ureters and delicate ureteral dissection is achieved throughout surgery, occult injuries can still occur. Surgeons should maintain a high index of suspicion of ureteral injury when evaluating patients for late presentations of postoperative complications.

Published: February 2017

PurposeThe purpose of this study is to explore the configuration of network ties that would have a positive impact on performance outcomes and test the presumed impact of multilevel strategic alliances on innovation and firm performance in a specific industry.Design/methodology/approachThis study comprises part of a larger project on the network relations of yacht-building firms operating in Turkey. Data of the study was collected through face-to-face interviews and questionnaires with 143 yacht-building firms operating in major yacht-building regions of the country.FindingsThe findings of the study indicated the presence of meaningful relationship between total number of (strong) network relations perceived as strategic alliance and overall innovation performance. The generally presumed positive relationship between innovation performance and firm performance was supported. The type of innovation performance that was found to be related to the total number of network ties perceived as strategic alliance at national and global levels was product innovation performance.Practical implicationsA possible contribution of this study for industry members would be the implications of the finding that indicates positive impact of strategic alliances with different actors of the industry.Originality/valueThis study contributes to the exploration of network configurations that have a positive impact on innovation and firm performance, by dealing with the impact of the size, strength and geographical level of network relations in one single study. The yacht-building industry as the empirical setting represents a specific category of industry that rests on customized individual or small-batch manufacturing requiring considerable interaction with customers and suppliers. Because no study exists on this topic, findings can inspire similar industries.
Formalizing in business networks as a tool for industrial policy
Authors: Guercini Simone , Tunisini Annalisa 
Published: February 2017

PurposeThe purpose of this paper is to examine the issue of “formalization” in business networks as an instrument of industrial policy. Formalization in business networks is not a debated topic but it can affect organizational and inter-organizational dynamics considerably. The aim of the paper is to understand if the introduction of a normative tool that enhances formalized networks can be effective to promote network aggregations among SMEs. Second, the aim is to understand if this formalization supports good-working networks, i.e., capable to introduce new products or to enter new markets/customers.Design/methodology/approachThe paper refers to a review of the literature and mainly to an empirical research on formalized network contracts (NCs) that have been conducted in the latest two years. This research has used both secondary data, collected accessing to databases and reports given by institutions and the government, and primary data, collected in specific direct interviews. These interviews have been concerned both institutions such as Chamber of Commerce, Confindustria and the Ministry of Economic Development and the Small Business Association, and 15 cases of NCs in Italy.FindingsThe formalization has consequences both internally and externally to the NC. Internally it can act as an element to reduce ambiguity and building elements of “fragile trust,” in the absence of basic elements of “resilient trust” and in the presence of changes in the competitive environment. Externally, the formalization through the NC allows the policy maker to identify more clearly companies’ aggregations in order to let them being destination of specific industrial policies. However even if the formalization has in some cases enhanced new networks’ creation, in many cases formalization has generated positive results when companies had already experienced networking outside the frame of the NC.Research limitations/implicationsFurther research on formalization in networks should be developed following the “history” of formalized networks over time in order to understand how much formalization should be used as a long-term tool for industrial policy.Practical implicationsThe paper can be useful both for companies that want to sign a NC and for the institutions developing industrial policies devoted to support companies’ aggregations in the form of NC.Originality/valueThe paper presents a new legal tool – the “NC” – introduced in 2009 by the Italian Government to enhance firms’ aggregation; second, the paper debates the topic of formalization in networks that is not much debated in literature; and finally, the paper also adopts an industrial economic approach and is among the few attempts to integrate industrial policies and industrial marketing and purchasing thinking.
Overall equipment effectiveness of tyre curing press: a case study
Authors: Saleem Faizan , Nisar Salman , Khan Muhammad Ali , Khan Sohaib Zia , Sheikh Mohammad Aslam 
Published: February 2017

Purpose
The purpose of this paper is to formulate a benchmark to increase the tyre curing press production rate while minimizing tyre curing press downtime and maintenance cost with the help of a maintenance management technique based on overall equipment effectiveness (OEE).

Design/methodology/approach
The methodology is based on determining the OEE of tyre curing press before and after rectifying the causes of failures. The failure mode and effect analysis (FMEA) technique is used to find out the root causes of repetitive failures in tyre curing press by using the risk priority number.

Findings
A significant change in the value of OEE is observed after rectifying the repetitive failures, which were determined using the FMEA technique. Thus, it is concluded that the OEE and FMEA assist in improving the industrial performance and competitiveness of the production equipment studied.

Research limitations/implications
This study is limited to determining the OEE of single equipment only, not the whole production system. Manufacturing facilities are dependent on the operating environment; therefore a comparison of two different manufacturing plants based on the OEE value would not be justified.

Practical implications
This study can be applied in any tyre manufacturing industry in order to take competitive benefits, such as reduction in equipment downtime, increased production and reduction in maintenance cost.

Originality/value
The angle from which the paper approaches the bottleneck problem in a tyre production line is original for the studied company and shows positives results. It allows the company to apply the same approach in its other production equipment, lines and factories to achieve improvement in industrial performance and competitiveness.

Authors: Kusumawardhani Mayang , Gundersen Ståle , Tore Markeset 
Published: February 2017

Purpose
The purpose of this paper is to study the current research approaches in asset management (AM), to evaluate some of the prevalent research methods in AM studies and to summarize the result into a building-block research that may provide design guidelines in AM studies.

Design/methodology/approach
AM publications were selected for this study using by online search engines and the publications were classified based on the appropriate research approaches. The results will be discussed and a suitable building-block research for AM studies will be constructed based on the identified research approaches.

Findings
The paper identifies, analyses and validates the research approaches found in a sample of online AM publications. The research-approaches and their associated methods will be discussed to develop understanding of the context of these approaches in AM research.

Research limitations/implications
The paper limits the study in publications within the AM field in the petroleum industry. However, the research methods that are presented covers the most common research methods found in publications. Thus, although the sample of publications may not represent the entire population, the same approach and result can be used in similar topics and conditions.

Originality/value
Researchers or practitioners can benefit from the building blocks of research to develop a research design for AM studies. Moreover, the paper also provides information on common research methods and data gathering techniques that can be used for similar studies.
Effects of Re‐heating Tissue Samples to Core Body Temperature on High‐Velocity Ballistic Projectile–tissue Interactions
Authors: Humphrey Caitlin , Henneberg Maciej , Wachsberger Christian , Maiden Nicholas , Kumaratilake Jaliya 
Published: February 2017

AbstractDamage produced by high‐speed projectiles on organic tissue will depend on the physical properties of the tissues. Conditioning organic tissue samples to human core body temperature (37°C) prior to conducting ballistic experiments enables their behavior to closely mimic that of living tissues. To minimize autolytic changes after death, the tissues are refrigerated soon after their removal from the body and re‐heated to 37°C prior to testing. This research investigates whether heating 50‐mm‐cube samples of porcine liver, kidney, and heart to 37°C for varying durations (maximum 7 h) can affect the penetration response of a high‐speed, steel sphere projectile. Longer conditioning times for heart and liver resulted in a slight loss of velocity/energy of the projectile, but the reverse effect occurred for the kidney. Possible reasons for these trends include autolytic changes causing softening (heart and liver) and dehydration causing an increase in density (kidney).
The state and food security discourses of Indonesia: feeding the bangsa
Authors: Neilson Jeff , Wright Josephine 
Published: February 2017

AbstractThis paper examines the ways in which discourses of food security and food sovereignty are articulated in Indonesia, exploring their emergence within particular historical episodes and considering how this change has informed their current deployment by state‐based actors. Looking first to the wider global discourses that encompass perspectives on food security and food sovereignty, this paper attempts to map a specifically Indonesian perspective on ‘food security’ (ketahanan pangan), and its relationship with ‘food sovereignty’ (kedaulatan pangan). Kedaulatan pangan emerges as a fundamentally endogenous political construct in Indonesia; that is, only marginally related to the broader global discourses of food sovereignty as espoused by organisations such as La Via Campesina. As presented by the Indonesian state, kedaulatan pangan is not oppositional to ketahanan pangan, as sometimes is portrayed elsewhere, but should instead be understood primarily as a rhetorical device to strengthen the role and function of the state and to reinforce existing associations between food security, state control, and national scale food self‐sufficiency. The Indonesian notion of kedaulatan pangan responds primarily to the scalar notion of feeding the bangsa, the abstract Indonesian word for ‘the nation’. The dominant discourse has been embraced and projected by political actors to further vested interests and also appears to be contributing to policy interventions with negative food security outcomes for some of Indonesia's most vulnerable individuals.
A powerful and efficient algorithm for breaking the links between aliased effects in asymmetric designs
Authors: Elsawah A. M. 
Published: February 2017

SummaryFractional factorial (FF) designs are no doubt the most widely used designs in experimental investigations due to their efficient use of experimental runs. One price we pay for using FF designs is, clearly, our inability to obtain estimates of some important effects (main effects or second order interactions) that are separate from estimates of other effects (usually higher order interactions). When the estimate of an effect also includes the influence of one or more other effects the effects are said to be aliased. Folding over an FF design is a method for breaking the links between aliased effects in a design. The question is, how do we define the foldover structure for asymmetric FF designs, whether regular or nonregular? How do we choose the optimal foldover plan? How do we use optimal foldover plans to construct combined designs which have better capability of estimating lower order effects? The main objective of the present paper is to provide answers to these questions. Using the new results in this paper as benchmarks, we can implement a powerful and efficient algorithm for finding optimal foldover plans which can be used to break links between aliased effects.
The development and correlates of gender role attitudes in African American youth
Authors: Lam Chun Bun , Stanik Christine , McHale Susan M. 
Published: February 2017

This research examined the longitudinal trajectories and family correlates of gender role attitudes in African American youth in a sample of 166 sibling pairs residing with their mothers and fathers. Multilevel modelling revealed that (1) girls and boys exhibited significant declines in gender attitude traditionality from ages 9 to 15 that levelled off through age 18, (2) mothers’ (but not fathers’) gender role attitude traditionality was positively related to youth's attitude traditionality, and (3) within‐person variation in mothers’ (but not fathers’) racial discrimination experiences was negatively related to within‐person variation in youth's gender role attitude traditionality. The utility of applying a cultural ecological framework within an ethnic homogenous, accelerated longitudinal design to understand African American family processes, in conjunction with the intersectionality between race and gender, is the focus of the discussion.
Statement of contribution

What is already known on this subject?

Gender role attitude traditionality declined for girls, but not for boys, in European and Mexican American families.

Little is known about the roles of African American parents in shaping their children's gender development.

What does this study add?

For African American girls and boys, gender role attitude traditionality declined from ages 9 to 15 and then levelled off through age 18.

At the between‐person level, African American mothers’, but not fathers’, attitude traditionality was positively linked to that of their children.

At the within‐person level, African American mothers’, but not fathers’, experiences of racial discrimination were negatively linked to their children's attitude traditionality.
Building a Large Database of Facial Movements for Deformation Model‐Based 3D Face Tracking
Authors: Sibbing Dominik , Kobbelt Leif 
Published: February 2017

AbstractWe introduce a new markerless 3D face tracking approach for 2D videos captured by a single consumer grade camera. Our approach takes detected 2D facial features as input and matches them with projections of 3D features of a deformable model to determine its pose and shape. To make the tracking and reconstruction more robust we add a smoothness prior for pose and deformation changes of the faces. Our major contribution lies in the formulation of the deformation prior which we derive from a large database of facial animations showing different (dynamic) facial expressions of a fairly large number of subjects. We split these animation sequences into snippets of fixed length which we use to predict the facial motion based on previous frames. In order to keep the deformation model compact and independent from the individual physiognomy, we represent it by deformation gradients (instead of vertex positions) and apply a principal component analysis in deformation gradient space to extract the major modes of facial deformation. Since the facial deformation is optimized during tracking, it is particularly easy to apply them to other physiognomies and thereby re‐target the facial expressions. We demonstrate the effectiveness of our technique on a number of examples.
Synchrony in population counts predicts butterfly movement frequencies
Authors: OLIVER TOM H. , POWNEY GARY D. , BAGUETTE MICHEL , SCHTICKZELLE NICOLAS 
Published: February 2017

1. Measuring functional connectivity, the ability of species to move between resource patches, is essential for conservation in fragmented landscapes. However, current methods are highly time consuming and expensive.2. Population synchrony‐ the correlation in time series of counts between two long‐term population monitoring sites, has been suggested as a possible proxy measure of functional connectivity. To date, population synchrony has been shown to correlate with proxies for movement frequency such as the coverage of suitable habitat types in intervening landscapes, and also least cost distances around hostile land cover types.3. This provides tentative evidence that synchrony is directly driven by movements of the focal species, but an alternative explanation is that these land cover types affect the movement of interacting species (e.g. natural enemies of the focal species) which can also drive synchronous population dynamics. Therefore, what is needed is a test directly relating population synchrony to movement frequencies of a focal species.4. Here we use data from a 21 year mark‐release‐recapture study and show that population synchrony does indeed predict movements of a focal butterfly speciesBoloria eunomia(Esper).5. There is growing evidence that population synchrony can be a useful conservation tool to measure functional connectivity.

SummaryObjectivesCarisbamate (CRS) is a novel monocarbamate compound that possesses antiseizure and neuroprotective properties. However, the mechanisms underlying these actions remain unclear. Here, we tested both direct and indirect effects of CRS on several cellular systems that regulate intracellular calcium concentration [Ca2+]i.MethodsWe used a combination of cellular electrophysiologic techniques, as well as cell viability, Store Overload‐Induced Calcium Release (SOICR), and mitochondrial functional assays to determine whether CRS might affect [Ca2+]i levels through actions on the endoplasmic reticulum (ER), mitochondria, and/or T‐type voltage‐gated Ca2+ channels.ResultsIn CA3 pyramidal neurons, kainic acid induced significant elevations in [Ca2+]i and long‐lasting neuronal hyperexcitability, both of which were reversed in a dose‐dependent manner by CRS. Similarly, CRS suppressed spontaneous rhythmic epileptiform activity in hippocampal slices exposed to zero‐Mg2+ or 4‐aminopyridine. Treatment with CRS also protected murine hippocampal HT‐22 cells against excitotoxic injury with glutamate, and this was accompanied by a reduction in [Ca2+]i. Neither kainic acid nor CRS alone altered the mitochondrial membrane potential (ΔΨ) in intact, acutely isolated mitochondria. In addition, CRS did not affect mitochondrial respiratory chain activity, Ca2+‐induced mitochondrial permeability transition, and Ca2+ release from the ER. However, CRS significantly decreased Ca2+ flux in human embryonic kidney tsA‐201 cells transfected with Cav3.1 (voltage‐dependent T‐type Ca2+) channels.SignificanceOur data indicate that the neuroprotective and antiseizure activity of CRS likely results in part from decreased [Ca2+]i accumulation through blockade of T‐type Ca2+ channels.
Managerial Discretion in Accruals and Informational Efficiency
Authors: Perotti Pietro , Windisch David 
Published: February 2017

AbstractIn this paper, we examine the relation between managerial discretion in accruals and informational efficiency. We measure managerial discretion in accruals by the absolute value of abnormal accruals. Assuming that efficient prices follow a random walk, we measure informational efficiency by using stock return variance ratios. We find that the absolute value of abnormal accruals is negatively associated with the price deviation from a random walk pattern, estimated in the 12‐month period subsequent to the accrual reporting; hence, future informational efficiency increases with the extent to which managers exercise discretion over accruals. The results are consistent with the view that discretionary accruals, on average, convey useful information to investors and facilitate the price convergence to its fundamental value. Our findings are robust to a battery of tests, including tests to validate both our measures of informational efficiency and our measure of managerial discretion in accruals.
