Authors: Khan Ambreen A. , Naeem S. , Ellahi R. , Sait Sadiq M. , Vafai K. 
Published: January 2020

Purpose
This study aims to investigate the effect of two-dimensional Darcy-Forchheimer flow over second-grade fluid with linear stretching. Heat transfer through convective boundary conditions is taken into account.

Design/methodology/approach
Nonlinear coupled governing equations are tackled with a homotopy algorithm, while for numerical computation the computer software package BVPh 2.0 is used. The convergence analysis is also presented for the validation of analytical and numerical results.

Findings
Valuation for the impact of key parameters such as variable thermal conductivity, Dufour and Soret effects and variable magnetic field in an electrically conducted fluid on the velocity, concentration and temperature profiles are graphically illustrated. It is observed from the results that temperature distribution rises by Dufour number whereas concentration distribution rises by Soret number. The Forchheimer number and porosity parameter raise the skin friction coefficient. The permeable medium has a vital impact and can help in reining the rate of heat transfer.

Practical implications
The permeable medium has a vital impact and can help in reining the rate of heat transfer.

Originality/value
To the best of the authors’ knowledge, this study is reported for the first time.
Preemptive scheduling with transportation delays between machines
Authors: Badaoui Ryma Zineb , Boudhar Mourad , Dahane Mohammed 
Published: January 2020

PurposeThis paper studies the preemptive scheduling problem of independent jobs on identical machines. The purpose of this paper is to minimize the makespan under the imposed constraints, namely, the ones that relate the transportation delays which are required to transport a preempted job from one machine to another. This study considers the case when the transportation delays are variable.Design/methodology/approachThe contribution is twofold. First, this study proposes a new linear programming formulation in real and binary decision variables. Then, this study proposes and implements a solution strategy, which consists of two stages. The goal of the first stage is to obtain the best machines order using a local search strategy. For the second stage, the objective is to determine the best possible sequence of jobs. To solve the preemptive scheduling problem with transportation delays, this study proposes a heuristic and two metaheuristics (simulated annealing and variable neighborhood search), each with two modes of evaluation.FindingsComputational experiments are presented and discussed on randomly generated instances.Practical implicationsThe study has implications in various industrial environments when the preemption of jobs is allowed.Originality/valueThis study proposes a new linear programming formulation for the problem with variable transportation delays as well as a corresponding heuristic and metaheuristics.
Teaching business as business
Authors: Lusoli Alberto 
Published: January 2020

Purpose
This paper aims to explore the early days of business education with the aim of understanding how the Harvard Business School (HBS) contributed to the constitution of “management” as a science-based profession. The research focuses on HBS signature pedagogy, the case method and its role in the institutionalization of managerial knowledge.

Design/methodology/approach
The research is based on a qualitative content analysis of HBS Annals published between 1908 and 1930. Through a manual coding of the Annals, the paper traces the diffusion of the case method in the curriculum and connects it with the institutional transformations that took place between 1908 and 1930.

Findings
The data show how HBS curriculum transitioned from lectures to case teaching in the aftermath of First World War. This pedagogy allowed HBS to demonstrate the possibility of systematically investigate management problems and to deliver business education at scale. The discussion argues that the case method, acting as a boundary object between business praxis and management theories, constituted management as a science-based profession.

Originality/value
Recent debates have emerged about case method’s ability to critically question socio-economic structures within which business is conducted. This paper contributes to the debate arguing that the historical and institutional factors leading to the affirmation of this pedagogical approach had a substantive role in the type of knowledge produced through its application. The findings challenge the idea that the affirmation of the case method is attributable to its epistemological primacy in investigating business problems.
The agency dilemma in anti-money laundering regulation
Authors: Naheem Mohammed Ahmad 
Published: January 2020

PurposeThe purpose of this paper is to provide a comprehensive theoretical framework that can be applied to the application of anti-money laundering (AML) regulation within the banking sector.Design/methodology/approachThe paper is linked to a PhD study to be published in Winter 2015/Spring 2016 that looks at trade-based money laundering and risk assessment using an agent–principal relationship to explain the underlying relationships affected by regulation in a ML context.FindingsThe paper finds that imposing regulation and assuming that the banking sector is simply an arm of law enforcement is not an effective approach and could actually contribute toward developing ML schemes that are too complex to be easily detected.Practical implicationsThe paper has implications for the banking, regulatory and law enforcement areas involved in ML and its detection.Originality/valueThe paper offers originality in providing a comprehensive multi-agency framework that is cognisant of all factors affected by AML regulation. It extends beyond existing work that has offered agency insights into various sectors of AML and ML partners.
Global knowledge management of suspicious transaction reporting system in Japan
Authors: Yasaka Noriaki 
Published: January 2020

Purpose
The purpose of this study is to make clear the structure of suspicious transaction reporting system in Japan from perspective of knowledge management. Because of the institutionalization of law, suspicious transaction reports in Japan have increased, but most of these reports are from financial institutions. Moreover, it cannot be said that the effect is used completely. It is important to increase the accuracy of the data mining method and incorporate the concept of knowledge management. Furthermore, it is desirable to use suspicious transactions from a global “knowledge management” perspective.

Design/methodology/approach
Based on the case of the Japanese transaction reporting system, Global knowledge management of suspicious transaction reporting system would be considered.

Findings
It is effective for money laundering countermeasures to deepen knowledge management of data → information → knowledge → wisdom. This brings the refinement of typology at the transaction unit to the upper level. This repetition has become more advanced and generalized knowledge. Knowledge transferred from national stage to international stage is organized as further information → knowledge → wisdom by collecting data based on that knowledge. By repeating this systematization in the process of knowledge management, global prevention measures against money laundering would be disseminated. As the result of these efforts, effective counter measures against money laundering could be sharper than before.

Originality/value
This is the first study about the analysis of suspicious transaction reporting system in Japan linked to the global knowledge management.
Detecting money laundering transactions with machine learning
Authors: Jullum Martin , Løland Anders , Huseby Ragnar Bang , Ånonsen Geir , Lorentzen Johannes 
Published: January 2020

Purpose
The purpose of this paper is to develop, describe and validate a machine learning model for prioritising which financial transactions should be manually investigated for potential money laundering. The model is applied to a large data set from Norway’s largest bank, DNB.

Design/methodology/approach
A supervised machine learning model is trained by using three types of historic data: “normal” legal transactions; those flagged as suspicious by the bank’s internal alert system; and potential money laundering cases reported to the authorities. The model is trained to predict the probability that a new transaction should be reported, using information such as background information about the sender/receiver, their earlier behaviour and their transaction history.

Findings
The paper demonstrates that the common approach of not using non-reported alerts (i.e. transactions that are investigated but not reported) in the training of the model can lead to sub-optimal results. The same applies to the use of normal (un-investigated) transactions. Our developed method outperforms the bank’s current approach in terms of a fair measure of performance.

Originality/value
This research study is one of very few published anti-money laundering (AML) models for suspicious transactions that have been applied to a realistically sized data set. The paper also presents a new performance measure specifically tailored to compare the proposed method to the bank’s existing AML system.
A Liberal Marxism? Mutual Care, Global Humanity and Minimum Utopia
Authors: Pitts Frederick Harry 
Published: January 2020

AbstractThis article surveys The Norman Geras Reader: ‘What’s There is There’, a recent collection of the work of Norman Geras, edited by Eve Garrard and Ben Cohen. The article explores the relevance of Geras’s attempted reconciliation between liberalism and Marxism to some of the key issues confronting the contemporary left: foreign policy and the failures of humanitarian intervention and non‐intervention; internationalism and the necessity for solidarity across borders in an age of nationalist populism; left approaches to totalitarianism and antisemitism; the possibilities and limitations of alternatives to and critiques of liberal capitalism; and the reinvigoration of utopian imaginaries and the futures they promise. It suggests that important lessons for the left can be unpicked from the contested legacy of the ‘decent leftism’ Geras represents, where reapplied in the wake of new political and diplomatic challenges.
The materials of indigeneity: slate and cement in a Taiwanese indigenous (Paiwan) mountain settlement
Authors: Gowlland Geoffrey 
Published: January 2020

AbstractThis article considers the implications of the adoption of cement and concrete as building materials in a mountain settlement of the Paiwan, one of the indigenous peoples of Taiwan. The presence of these materials in an indigenous settlement might at first glance be interpreted as a sign of cultural assimilation. This article suggests rather that, by paying close attention to the ways in which locals engage with the changing properties of imported materials in work and daily life, a more complex understanding can be gained of the negotiated relations of power between indigenous people, the state, and market forces, as well as the role of materials in these negotiations. For the Paiwan, creative engagements with foreign materials and their changing properties have, at various moments, represented ways of adapting to the pressures to assimilate, or, conversely, resulted in expressions of cultural resilience.

Authors: Baxter Megan , Denny Kerina J , Keijzers Gerben 
Published: January 2020

AbstractObjectiveTo describe the current practice of prophylactic antibiotic prescribing for patients presenting to the ED with a dog bite, and compare management against existing guidelines.MethodsWe performed a descriptive retrospective study on all consecutive patients who presented to one tertiary teaching hospital and one regional district hospital in Southeast Queensland between 1 July 2017 and 30 June 2018 with a presentation of a dog bite. Data on demographics and management were collected from the electronic medical record using a standardised data collection tool. Risk factors supporting prophylaxis were taken from the electronic Therapeutic Guidelines.ResultsOf the 336 patients included for analysis, 299 received antibiotics, of which 23 were for established infection. A total of 276 (82% of overall cohort) received a prescription for prophylactic antibiotics, either in hospital (ED or admitting ward) and/or on discharge. Of the 178 patients who received prophylactic antibiotics in hospital, 91 (51.1%) received intravenous antibiotics. Of the patients who presented to ED without a previously established infection 271 (86.6%) received prophylactic antibiotics on discharge. Over one quarter (27.5%) of patients who were given prophylactic antibiotics did not meet any high‐risk factors as outlined in guidelines.ConclusionProphylactic antibiotics are extensively used for patients with dog bites. There is scope to rationalise antibiotic use and route of antibiotic administration in patients with dog bites.

Published: January 2020

AbstractA continuous terrestrial succession was recovered from the Songke‐2 (SK‐2) borehole in the Songliao Basin, Northeastern China. This borehole provides a unique material for further research on the continental paleoclimate during Cretaceous greenhouse period, following a series of achievements of the Songke‐1 (SK‐1) core. In this study, thorium (Th) logging data were chosen as a paleoclimate proxy to conduct a detailed cyclostratigraphic analysis. The Th series varies quasi‐periodically; power spectra and evolutionary fast Fourier transformation (FFT) analysis reveal significant cycles in the Quantou (K2q), Qingshankou (K2qn), Yaojia (Ky and Nenjiang (K2n) formations. The ratio of cycle wavelengths in these stratigraphic units is approximately 20:5:2:1, corresponding to long orbital eccentricity (405 kyr), short orbital eccentricity (100 kyr), obliquity (37 kyr), and precession cycles (22.5 kyr and 18.4 kyr). The durations of the K2n, K2y, K2qn and K2q are estimated as 6.97, 1.83, 5.30 and 4.52 Myr, respectively, based on the constructed ∼18.62 Myr “floating” astronomical time scale (ATS). Comparison of the durations between the SK‐1 s and SK‐2 boreholes exhibits a slight difference of 0.06 Myr and 0.459 Myr for K2qn and K2y. Nevertheless, our ATS of K2n supports the chronostratigraphic frame constructed by the CA‐ID‐TIMS data of the SK‐1s borehole. This new “floating” ATS provides precise numerical ages for stratigraphic boundaries, biozones and geological events in the Songliao Basin, and can serve as a basis for correlation of strata and events between marine and terrestrial systems.
Destruction of the Northern Margin of the North China Craton in Mid‐Late Triassic: Evidence from Asthenosphere‐derived Mafic Enclaves in the Jiefangyingzi Granitic Pluton from the Chifeng Area, Southern Inner Mongolia

Published: January 2020

AbstractThe petrology, geochronology and geochemistry of the mafic enclaves in the Mid‐Late Triassic Jiefangyingzi pluton from Chifeng area, southern Inner Mongolia, in China are studied to reveal their petrogenetic relationship with the host pluton. Furthermore, the coeval magmatic assemblage and its petrogenesis on the northern margin of the North China craton (NCC) are studied synthetically to elucidate their tectonic setting and the implications for the destruction of the NCC. Zircon U‐Pb dating reveals that the mafic enclaves formed at 230.4 ± 2.2 Ma, which is similar to the age of the host pluton. The most basic mafic enclaves belong to weak alkaline rocks, and they display rare earth element (REE) and trace element normalized patterns and trace element compositions similar to those of ocean island basalt (OIB). In addition, they have positive ∊Nd(t) values (+3.84 to +4.94) similar to those of the Cenozoic basalts on the northern margin of the NCC. All of these geochemical characteristics suggest that the basic mafic rocks originated from the asthenosphere. Petrological and geochemical studies suggest that the Jiefangyingzi pluton and the intermediate mafic enclaves were formed by the mixing of the asthenosphere‐derived and crust‐derived magmas in different degrees. The Mid‐Late Triassic magmatic rocks on the northern margin of the NCC could be classified into three assemblages according to their geochemical compositions: alkaline series, weak alkaline–sub‐alkaline series and sub‐alkaline series rocks. Petrogenetic analyses suggest that the upwelling of the asthenosphere played an important role in the formation of these Mid‐Late Triassic magmatic rocks. Basing on an analysis of regional geological data, we suggest that the northern margin of the NCC underwent destruction due to the upwelling of the asthenosphere during the Mid‐Late Triassic, which was induced by the delamination of the root of the collisional orogeny between Sino‐Korean and Siberian paleoplates in Late Permian.
Development of Sulfuric Acid Speleogenetic Deposits within Cavernous Middle Eocene Beds: Inference on Hydrocarbon Gas Seepages, Giza Pyramids Plateau, Egypt
Authors: BADAWY Hanan S. 
Published: January 2020

AbstractDevelopment of sulfuric acid speleogenetic mineral deposits within cavernous middle Eocene beds of the Pyramids plateau is linked to hydrocarbon gas seepages. The work carried out field observations, binocular, polarizing, scanning and transmitted electron microscopy investigation, X‐ray diffraction and X‐ray fluorescence analyses. The morphological and petrographic features and chemical composition of the studied mineral deposits reveal a hypogene sulfuric acid speleogenesis. A model comprised of the following stages can be used to explain the presence of these features. (1) Ascent of hydrogen sulfide (H2S) gas associated with hydrocarbon seepages from the Cretaceous reservoirs under reducing conditions followed by oxidation to sulfuric acid (H2SO4), (2) descent of carbonic acid (H2CO3)‐rich solution generated from surface sources, (3) reaction of H2SO4 and H2CO3 with the calcareous and argillaceous host rocks, (4) formation of H2SO4 speleogenetic by‐products represented by natroalunite, aluminium‐phosphate‐sulfate, hydrated halloysite and Fe/Mn oxides within the replacive gypsum, and (5) subsequent stresses due to the formation of nearby stratiform cavities gave rise to the development of fractures/veinlets filled with displacive fibrous satinspar gypsum. The study sets the paleokarst features of the Giza Pyramids plateau within a hypogene sulfuric acid karst system developed by the action of groundwater containing H2S, H2SO4 and H2CO3.

Published: January 2020

AbstractBackgroundBreast cancer (BC) is a common cancer in women worldwide. Emerging evidence has indicated that circular RNA hsa‐circ_0007255 (circ_0007255) is a prognostic mediator in BC progression. However, the functional role of circ_0007255 needs to be determined.MethodsThe expression of circ_0007255, microRNA (miR)‐335‐5p, and SIX Homeobox 2 (SIX2) was evaluated using quantitative real‐time polymerase chain reaction (qRT‐PCR) or western blot assay. Actinomycin D and RNase R treatment was performed to analyze the stability of circ_0007255. Additionally, Seahorse extracellular flux, colony formation and transwell analyses were carried out to detect oxygen consumption ratio (OCR), colony formation and cell mobility, respectively. The interaction between miR‐335‐5p and circ_0007255 or SIX2 was confirmed via dual‐luciferase reporter assay. A xenograft tumor model was established to explore the role of circ_0007255 in vivo.ResultsCirc_0007255 and SIX2 were overexpressed, but miR‐335‐5p was diminished in BC tissues and cells. Circ_0007255 absence inhibited oxygen consumption, colony formation, cell migration and invasion, and these effects were particularly abrogated via miR‐335‐5p upregulation in BC cells. Moreover, SIX2 deficiency eliminated the promotion effects of miR‐335‐5p inhibitor on oxygen consumption, colony formation, and cell mobility in BC cells. Importantly, circ_0007255 inhibited tumor growth in vivo. Mechanically, circ_0007255 was a sponge of miR‐335‐5p to regulate SIX2 expression in BC progression.ConclusionCirc_0007255 functioned as a novel oncogene in the progression of BC by regulating miR‐335‐5p/SIX2 axis, and might be a promising biomarker for BC treatment.Key pointsSignificant findings of the study: Levels of circ_0007255 and SIX2 were upregulated, but miR‐335‐5p was diminished in BC tissues and cells. Circ_0007255 was an oncogene in BC development and exerted its function via miR‐335‐5p/SIX2 axis in BC. Tumor growth was reduced by circ_0007255 absence.What this study adds: Circ_0007255 functioned as a novel oncogene in the progression of BC by regulating miR‐335‐5p/SIX2 axis, and might be a promising biomarker for BC treatment.
Practical insight into upright breech birth from birth videos: A structured analysis
Authors: Reitter Anke , Halliday Alexandra , Walker Shawn 
Published: January 2020

AbstractBackgroundWe aimed to identify common features of upright vaginal breech births with good outcomes to refine a physiological approach to teaching breech birth.MethodsWe performed a structured analysis of 42 videos of successful upright breech births (eg, kneeling, hand/knees), facilitated by obstetricians (n = 34) and midwives (n = 8) in nine different countries. Precise timings and relevant clinical details were recorded on an Excel spreadsheet. Each video was analyzed twice by at least two members of the research team. Time‐to‐event intervals, frequencies of interventions, and descriptive statistics were calculated using SPSS.ResultsA completely spontaneous (labor mechanisms and maternal effort only) birth occurred in 14/42 (33%) cases. The median time between the birth of the fetal pelvis and the head in all births was 1:52 (IQR 1:05,2:46; min:sec). Lack of spontaneous rotation to a sacro‐anterior position by the time the fetus had emerged to the nipple line was strongly associated with fetal arm entrapment. The following maneuvers were used: shoulder press to flex the aftercoming head in midpelvis or outlet (n = 24), sweeping down arm/s (n = 12), buttock lift to assist shoulder press (n = 6), modified Mauriceau (n = 6), rotational maneuvers to release an entrapped arm (n = 6), elevate and rotate fetal head to assist engagement (n = 2), and conversion into supine maternal position (n = 2).ConclusionsMost upright breech births occur within 3 minutes of the birth of the fetal pelvis. Upright breech birth attendants use variations of traditional maneuvers. We introduce a physiological breech algorithm as an initial timekeeping framework for teaching, research, and practice.
