Low milk supply and the pediatrician
Authors: Riddle Sarah W. , Nommsen-Rivers Laurie A. 
Published: March 2017

Purpose of review
Human milk is the optimal food for human infants, and provides many diverse and well described benefits for both mother and infant. Low milk supply, whether perceived or actual, is one of the most common reasons why mothers stop breastfeeding. Breastfeeding mothers often seek out the guidance and support of their pediatrician in evaluating and resolving milk production concerns.

Recent findings
Recent evidence supports the importance of breastfeeding for maternal and child health in both developing and developed countries. Lack of knowledge regarding optimal breastfeeding management accounts for the large majority of low milk supply concerns, but there is emerging evidence that impaired glucose tolerance may contribute to intrinsic low milk supply.

Summary
Breastfeeding mother–infant dyads should be followed closely until lactation is well established and the infant is gaining well. Further research is needed to understand the physiologic contributors to low milk supply and to guide evidence-based interventions to optimize maternal success in reaching breastfeeding goals, particularly for women of poorer metabolic health.

Fetal growth assessment is important to identify fetuses with abnormal fetal growth that are at increased risk of perinatal morbidity and mortality. Serial measurement of symphysis-fundal height (SFH) is the recommended, inexpensive, and first-level screening tool in both low- and high-risk pregnancies.
Modelling turbulent boundary layer flow over fractal-like multiscale terrain using large-eddy simulations and analytical tools
Authors: Yang X. I. A. , Meneveau C. 
Published: March 2017

In recent years, there has been growing interest in large-eddy simulation (LES) modelling of atmospheric boundary layers interacting with arrays of wind turbines on complex terrain. However, such terrain typically contains geometric features and roughness elements reaching down to small scales that typically cannot be resolved numerically. Thus subgrid-scale models for the unresolved features of the bottom roughness are needed for LES. Such knowledge is also required to model the effects of the ground surface ‘underneath’ a wind farm. Here we adapt a dynamic approach to determine subgrid-scale roughness parametrizations and apply it for the case of rough surfaces composed of cuboidal elements with broad size distributions, containing many scales. We first investigate the flow response to ground roughness of a few scales. LES with the dynamic roughness model which accounts for the drag of unresolved roughness is shown to provide resolution-independent results for the mean velocity distribution. Moreover, we develop an analytical roughness model that accounts for the sheltering effects of large-scale on small-scale roughness elements. Taking into account the shading effect, constraints from fundamental conservation laws, and assumptions of geometric self-similarity, the analytical roughness model is shown to provide analytical predictions that agree well with roughness parameters determined from LES.

Dipolar extracellular potentials generated by axonal projections
Authors: McColgan Thomas , Liu Ji , Kuokkanen Paula T , Carr Catherine E , Wagner Hermann , Kempter Richard 
Published: March 2017

AbstractExtracellular field potentials (EFPs) are an important source of information in neuroscience, but their physiological basis is in many cases still a matter of debate. Axonal sources are typically discounted in modeling and data analysis because their contributions are assumed to be negligible. Here, we show experimentally and theoretically that contributions of axons to EFPs can be significant. Modeling action potentials propagating along axons, we showed that EFPs were prominent in the presence of a terminal zone where axons branch and terminate in close succession, as found in many brain regions. Our models predicted a dipolar far field and a polarity reversal at the center of the terminal zone. We confirmed these predictions using EFPs from the barn owl auditory brainstem where we recorded in nucleus laminaris using a multielectrode array. These results demonstrate that axonal terminal zones produce EFPs with considerable amplitude and spatial reach.

Published: March 2017

PurposeThe purpose of this paper is to reformulate the governing equations incorporating major variables and parameters for the design a Micro Air Vehicle (MAV), to meet the desired mission and design requirements.Design/methodology/approachMathematical models for various spherical and cylindrical Coandă MAV configurations were rederived from first principles, and the performance measures were defined. To verify the theoretical prediction to a certain extent, a computational fluid dynamic (CFD) simulation for a Coandă MAV generic models was performed.FindingsThe major variables and parameters of Coandă MAV have been formulated into practical guidelines, which relate the lift (or thrust) produced for certain input variables, particularly the Coandă MAV jet momentum coefficient. The influences of the geometrical parameters are elaborated.Research limitations/implicationsThe present analysis on Coandă jet-configured MAV is focused on the lift generation due to the Coandă jet effect through a meticulous analysis. The effects of viscosity, the Coandă jet thickness, the radius of curvature of the surface and the stability of Coandă jet are not considered and will be the subject of the following work.Practical implicationsThe results obtained can be used for sizing in the preliminary design of Coandă MAVs.Originality/valuePhysical and mathematical models were developed which can describe the physical phenomena of the flow field near the Coandă MAV surfaces influenced by Coandă jet sheets and for obtaining a relationship between relevant variables and parameters to the lift of practical interest.
Experimental facilities for modal testing
Authors: de Barros Everaldo , Juliani Fernando , de Camargo Leandro Ribeiro 
Published: March 2017

Purpose
The experimental modal analysis requires good knowledge of various engineering fields, such as mechanical vibrations, transducers used in vibration measurement, transducers and system calibration methods, data acquisition systems, digital signal processing and system identification. Test facilities constitute a key factor for improving the quality of the estimated modal model. This paper aims to describe the experimental facilities at the Institute of Aeronautics and Space (IAE) Modal Testing Laboratory in terms of associated instrumentation and data acquisition system, metrological aspects and computational resources. The discussion is completed with a practical application showing a ground vibration testing (GVT) of an unmanned aerial vehicle (UAV).

Design/methodology/approach
The experimental facilities were evaluated in a typical GVT, using three shakers in both vertical and horizontal excitations and 88 response measurement points. The global excitation method was used to excite all desired modes. The reliability of the experimental modal model was validated by an auto modal assurance criterion matrix for the measured modes of the structure.

Findings
The experimental facilities were successfully used for validating the dynamical characteristics of the UAV under testing.

Originality/value
The modal test facilities of the Modal Testing Laboratory at the IAE, the main research center of the Brazilian Air Force, are described in this paper.
Imperfect maintenance model for estimating aircraft fleet availability
Authors: Knezevic Aleksandar , Vasov Ljubisa , Vlacic Slavisa , Kostic Cedomir 
Published: March 2017

Purpose
The purpose of this paper is to define conditions under which improved availability of fleet of G-4 jet trainers is obtained, and optimization of intermediate-level maintenance through imperfect maintenance model application. This research has been conducted based on available knowledge, and experience gained by performing intermediate-level maintenance of Serbian Air Force aircrafts.

Design/methodology/approach
Analysis of the data collected from daily maintenance reports, and the analysis of maintenance technology and organization, was performed. Based on research results, a reliability study was performed. Implementation of imperfect maintenance with its models of maintenance policies (especially a quasi-renewal process and its treating of reliability and optimal maintenance) was proposed to define new maintenance parameters so that the greater level of availability could be achieved.

Findings
The proposed methodology can potentially be applied as a simple tool to estimate the present maintenance parameters and to quickly point out some deficiencies in the analyzed maintenance organization. Validation of this process was done by conducting a reliability case study of G-4 jet trainer fleet, and numerical computations of optimal maintenance policy.

Research limitations/implications
The methodology of the availability estimation when reliability parameters were not tracked by the maintenance organization, and optimization of intermediate-level maintenance, has so far been applied on G-4 jet trainers. Moreover, it can be potentially applied to other aircraft types.

Originality/value
Availability estimation and proposed optimization of intermediate maintenance is based on a survey of data for three years of aircraft fleet maintenance. It enables greater operational readiness (due to a military rationale) with possible cost reduction as a consequence but not as a goal.
“Don’t judge me”: narratives of living with FGM
Authors: Recchia Natasha , McGarry Julie 
Published: March 2017

Purpose
The purpose of this paper is to facilitate a participant led arts-based workshop for survivors of female genital mutilation (FGM) in order to explore their experiences and impact of FGM on health and wellbeing, and to use the artefacts to inform development of an e-learning resource.

Design/methodology/approach
The study utilised a creative narrative approach which included the sharing of personal stories, the creation of pottery models and the sharing of artefacts. A narrative approach was chosen as the methodology for the study as narratives are now well established within qualitative research as a meaningful way in which the voices of participants take precedence over those of the researcher. Six women who are living with FGM agreed to take part.

Findings
The composition of the workshop essentially encompassed two main strands: the creation of a persona and sharing artefacts. These are described in detail with supplementary images included wherever appropriate. The authors have not attempted to present the findings of the workshop from the perspective of the researcher but have rather enabled the findings to speak for themselves.

Research limitations/implications
There is a paucity of studies which have explored women’s experiences of living with FGM and the impact on health and well-being. The findings suggest that there is further scope for research and practice development which examines the impact of education on professional’s approaches to FGM.

Originality/value
This study and the wider focus towards the impact of FGM beyond the physical or procedural aspects of FGM offer a contribution to the evolving evidence base in this field.
Information and reformation in KM systems: big data and strategic decision-making
Authors: Intezari Ali , Gressel Simone 
Published: March 2017

PurposeThe purpose of this paper is to provide a theoretical framework of how knowledge management (KM) systems can facilitate the incorporation of big data into strategic decisions. Advanced analytics are becoming increasingly critical in making strategic decisions in any organization from the private to public sectors and from for-profit companies to not-for-profit organizations. Despite the growing importance of capturing, sharing and implementing people’s knowledge in organizations, it is still unclear how big data and the need for advanced analytics can inform and, if necessary, reform the design and implementation of KM systems.Design/methodology/approachTo address this gap, a combined approach has been applied. The KM and data analysis systems implemented by companies were analyzed, and the analysis was complemented by a review of the extant literature.FindingsFour types of data-based decisions and a set of ground rules are identified toward enabling KM systems to handle big data and advanced analytics.Practical implicationsThe paper proposes a practical framework that takes into account the diverse combinations of data-based decisions. Suggestions are provided about how KM systems can be reformed to facilitate the incorporation of big data and advanced analytics into organizations’ strategic decision-making.Originality/valueThis is the first typology of data-based decision-making considering advanced analytics.

Authors: Holzmann Patrick , Breitenecker Robert J. , Soomro Aqeel A. , Schwarz Erich J. 
Published: March 2017

Purpose
3D printing possesses certain characteristics that are beneficial for user entrepreneurship. The purpose of this paper is to investigate the business models of user entrepreneurs in the 3D printing industry. In addition, various business opportunities in 3D printing open to user entrepreneurs are classified according to their attractiveness.

Design/methodology/approach
The authors review the literatures on user entrepreneurship and on business models. Data from eight user entrepreneurs in Europe and North America are analyzed, applying qualitative content analysis. Multiple correspondence analysis is used to analyze their respective business models.

Findings
User entrepreneurs in the 3D printing utilize a number of different business models, which show similarities in particular business model components. User entrepreneurs focus primarily on the combination of low opportunity exploitation cost and a large number of potential customers.

Research limitations/implications
Online business seems to be beneficial for user entrepreneurship in 3D printing. Policy makers can foster user entrepreneurship by expanding entrepreneurship education and lowering administrative barriers of business foundation. The results of this study are based on a small European and North American sample. Thus, they might not be applicable to other markets.

Originality/value
This is the first study of user entrepreneur business models in 3D printing and, thus, contributes to the literature on business models and on user entrepreneurship. In view of the novelty of the field, the business models identified in the study could serve as blueprints for prospective user entrepreneurs in 3D printing.
Detrimental effects of post-IPO corporate governance changes
Authors: Atinc Guclu , Kroll Mark , Walters Bruce 
Published: March 2017

PurposeThe authors contend that immediately following the initial public offering (IPO), the new owners that replace the original ones are likely to request changes in two corporate governance mechanisms, board of directors and top management teams (TMTs). Following these alterations, the purpose of this paper is to propose that such changes will be detrimental for the performance of young entrepreneurial firms.Design/methodology/approachThis study examines the post-IPO governance changes in young entrepreneurial firms. The sample consists of 185 companies that went public between 2001 and 2005. A hierarchical linear regression approach with the appropriate control variables is adopted to test the proposed hypotheses.FindingsThe results revealed that, following the changes in ownership structure post-IPO, changes are observed in one of the corporate governance mechanisms the authors considered, boards of directors, but not TMTs. Consistent with the general theme of this study, the authors also observed a negative impact of changes in boards of directors on subsequent firm performance; this was not the case with TMTs.Research limitations/implicationsContrary to the fundamental contentions of agency theory, the results highlight the need for adopting a different approach for young entrepreneurial firms.Practical implicationsThe findings highlight the importance of preserving the entrepreneurial efficacy of young entrepreneurial firms.Originality/valueThis paper challenges the fundamental contentions of agency theory in the case of young entrepreneurial firms. The results demonstrate that post-IPO shareholders’ interference with the governance mechanisms results in lower performance.
Returns to acquirers of listed and unlisted targets: an empirical study of Australian bidders
Authors: Nguyen Pascal , Rahman Nahid , Zhao Ruoyun 
Published: March 2017

Purpose
This paper aims to evaluate the robustness of the listing effect in Australia, that is whether acquisitions of private firms create more value to the bidding firm’s shareholders than acquisitions of publicly listed firms.

Design/methodology/approach
The authors analyze the market reaction to the announcement of takeover bids initiated by Australian public firms on private and public targets over the period 1990-2011. The analysis controls for a wide range of bidder, deal and target country characteristics that are likely to correlate with the target’s listing status and acquirer abnormal returns. The authors also use a selection model to address the endogenous choice of the target’s listing status.

Findings
The results indicate that bidders experience significantly higher abnormal returns of about 1.7 per cent in the 11-day event window when the target is a private firm. The authors show that this result is broad-based and persistent. It does not appear to depend on whether the target is small or large; whether it is related or unrelated to the bidder’s industry; whether it is in the resources sector; and whether the transaction is domestic or cross-border. They find some evidence that bidder returns might be stronger for larger acquisitions, for unrelated targets, and in poor market conditions such as in the wake of the recent global financial crisis.

Research limitations/implications
The research would benefit from the inclusion of the bidding firm’s ownership and governance characteristics.

Practical implications
The results support the view that market frictions contribute to make private firms attractive targets.

Originality/value
The analysis confirms the pervasiveness of the listing effect in a market characterized by a lesser degree of competition, higher search costs and the significance of the natural resources sector.

Published: March 2017

AbstractAimThe 2012 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for polymyalgia rheumatica (PMR) were published in 2012. The present study aimed to assess the 2012 EULAR/ACR classification criteria for PMR in Japanese patients diagnosed with PMR using Bird's criteria.MethodsThe study included 75 patients diagnosed using Bird's criteria. The patients were divided into fulfilled and not‐fulfilled groups according to whether they met the 2012 EULAR/ACR classification criteria for PMR. The factors in the new criteria were morning stiffness duration > 45 min, hip pain or limited range of motion, absence of rheumatoid factor or anti‐citrullinated protein antibody, and absence of other joint involvement.ResultsThirty‐two of the patients diagnosed with PMR using Bird's criteria met the new EULAR/ACR classification criteria, while the remaining 43 patients did not meet the new criteria. Among the factors, only morning stiffness duration > 45 min was an independent predictive factor.ConclusionsA morning stiffness duration > 45 min is the only independent predictive factor for differentiating patients diagnosed according to the new 2012 EULAR/ACR classification criteria for PMR.
Characteristics of symptomatic men with testicular microlithiasis – A Danish cross‐sectional questionnaire study
Authors: Pedersen M. R. , Møller H. , Rafaelsen S. R. , Jørgensen M. M. B. , Osther P. J. , Vedsted P. 
Published: March 2017

SummaryTesticular microlithiasis (TML) is an incidental finding at ultrasonography of the scrotum. A link between testicular microlithiasis and testicular cancer has been suggested. However, the majority of studies are retrospective using ultrasonography with minor data on health status and life style characteristics. Our objective was to investigate if lifestyle and health are associated with TML. In 2014, we conducted a self‐administered questionnaire survey including 1538 men, who all due to testicular/scrotal symptoms had an ultrasound investigation of the scrotum during 2004–2013. The men were divided into men with TML and men without. The 23‐items questionnaire included items on age, height, weight, lifestyle (alcohol consumptions, smoking habits, workload, exercise and food), previous diseases in the testicles, pain and consumption of analgesics. The prevalence of TML was 12.8%. Overall, lifestyle factors did not vary between men with or without TML. However, men with TML did consume more crisp than men without. Development of TML was not associated to classic life style factors such as alcohol consumption, smoking habits, or mothers smoking during pregnancy. Also, age and height could not be linked to presence of TML. We did find, however, that men with TML experienced less physical activity and consumed more crisp than men without TML. Since ingestion of crisps has potential carcinogenic effect (acrylamide), this finding needs confirmation in a separate study.
