Deux Collections De Sentences Coptes Inédites : Paroles D’Instruction D’Athanase ET Paroles Anonymes
Authors: Crégheur Eric 
Published: July 2019

Abstract
This essay presents an edition and translation of two hitherto unedited Coptic collections of sayings preserved in the Royal Ontario Museum (Toronto, Canada), Words of Instruction attributed to Athanasius of Alexandria and a group of anonymous Sayings, once wrongly attributed to Evagrius. After a description of the manuscript (characteristics, provenance, context of its acquisition) and of its contents (texts, language, previous research), I present in greater detail the two previously unedited collections of sayings found in it (characteristics of the sayings, original language, milieu of composition, attribution, dating, etc.). Finally, I offer brief comments on their place among similar collections. The edition and French translation of the two collections follow, each accompanied by notes.
Contracting on Credit Ratings: Adding Value to Public Information
Authors: Parlour Christine A , Rajan Uday 
Published: July 2019

Abstract
We consider the role of credit ratings when contracts between investors and portfolio managers are incomplete. In our model, a credit rating and a price on a risky bond both provide verifiable signals about a non-contractible state. We allow the investor to both impose ex ante restrictions on the manager’s action and provide outcome-based compensation. The optimal contract is a prohibitive one when the rating and price indicate a high likelihood of a low state, and relies on wages when the low state is less likely. We provide some observable implications of our contracting approach to ratings. (JEL G24, D86)
One Central Bank to Rule Them All*
Authors: Brusa Francesca , Savor Pavel , Wilson Mungo 
Published: July 2019

Abstract
While global stock markets enjoy high returns on days surrounding Federal Open Market Committee (FOMC) meetings, there is no comparable result for other central banks either internationally or, more surprisingly, domestically. Neither announcement surprises nor currency moves drive these findings, which hold even for stocks with a domestic focus. The difference in announcement premia is not explained by economy size, exposure to multinationals, or policy activism. We conclude that the Fed exerts a unique impact on global equities. Consistent with this hypothesis, uncertainty drops across global markets following FOMC announcements but not those of other central banks. Furthermore, the Fed is generally the leader among central banks in setting monetary policy.

Abstract
Interventional cardiology procedures can involve relatively high radiation doses compared to general radiography. During coronary angiography (CAG) and percutaneous transluminal coronary intervention (PCI), the same area is exposed to radiation for a long period. In this study, radiation exposure data of 1071 examinations in Korean hospitals were collected, and the achievable dose (AD) and diagnostic reference levels (DRLs) in actual medical practice for two types of interventional cardiology procedures in Korea were established. In CAG, 75th percentile DRLs and AD of the total kerma-area product were 47.0 and 33.1 Gy·cm 2, respectively. In PCI, those values were 171.3 and 102.6 Gy·cm2, respectively. This is the first study to introduce the DRLs for cardiovascular interventional procedures in Korea. These results will help optimise the interventional cardiology procedures for Korean cardiac centres.
Energy efficient synaptic plasticity
Authors: Li Ho Ling , van Rossum Mark C. W. 
Published: July 2019

AbstractMany aspects of the brain’s design can be understood as the result of evolutionary drive towards efficient use of metabolic energy. In addition to the energetic costs of neural computation and transmission, experimental evidence indicates that synaptic plasticity is metabolically demanding as well. As synaptic plasticity is crucial for learning, we examine how these metabolic costs enter in learning. We find that when synaptic plasticity rules are naively implemented, training neural networks requires extremely large amounts of energy when storing many patterns. We propose that this is avoided by precisely balancing labile forms of synaptic plasticity with more stable forms. This algorithm, termed synaptic caching, boosts energy efficiency manifold. Our results yield a novel interpretation of the multiple forms of neural synaptic plasticity observed experimentally, including synaptic tagging and capture phenomena. Furthermore our results are relevant for energy efficient neuromorphic designs.
Quantitative analysis ofin vivomethionine oxidation of the human proteome

Published: July 2019

ABSTRACTThe oxidation of methionine is an important posttranslational modification of proteins with numerous roles in physiology and pathology. However, the quantitative analysis of methionine oxidation on a proteome-wide scale has been hampered by technical limitations. Methionine is readily oxidizedin vitroduring sample preparation and analysis. In addition, there is a lack of enrichment protocols for peptides that contain an oxidized methionine residue; making the accurate quantification of methionine oxidation difficult to achieve on a global scale. Herein, we report a methodology to circumvent these issues by isotopically labeling unoxidized methionines with18O labeled hydrogen peroxide and quantifying the relative ratios of18O and16O oxidized methionines. We validate our methodology using artificially oxidized proteomes made to mimic varying degrees of methionine oxidation. Using this method, we identify and quantify a number of novel sites ofin vivomethionine oxidation in an unstressed human cell line.

AbstractFunctional injectisomes of the type-3 secretion system assemble into highly defined and stoichiometric bacterial molecular machines essential for infecting human and other eukaryotic cells. However, the mechanism that governs the regulated step-wise assembly process from the nucleation-phase, to ring-assembly, and the filamentous phase into a membrane embedded needle complex is unclear. We here report that the formation of a megadalton-sized needle complexes fromSalmonella entericaserovar Typhimurium (SPI-1,Salmonellapathogenicity island-1) with proper stoichiometries is highly structurally controlled competing against the self-assembly propensity of injectisome components, leading to a highly unusual structurally-pleiotropic phenotype. The structure of the entire needle complex from pathogenic injectisomes was solved by cryo electron microscopy, focused refinements (2.5-4 Å) and co-variation analysis revealing an overall asymmetric arrangement containing cyclic, helical, and asymmetric sub-structures. The centrally located export apparatus assembles into a conical, pseudo-helical structure and provides a structural template that guides the formation of a 24-mer cyclic, surrounding ring, which then serves as a docking interface comprising three different conformations for sixteen N-terminal InvG subunits of the outer secretin ring. Unexpectedly, the secretin ring excludes the 16thprotein chain at the C-terminal outer ring, resulting in a pleiotropic 16/15-mer ring and consequently to an overall 24:16/15 basal body structure. Finally, we report how the transition from the pseudo-helical export apparatus into the helical filament is structurally resolved to generate the protein secretion channel, which provides the structural basis to restrict access of unfolded effector substrates. These results highlight the diverse molecular signatures required for a highly coordinated assembly process and provide the molecular basis for understanding triggering and transport of unfolded proteins through injectisomes.

ABSTRACTAberrant mucin type O-linked glycosylation is a common occurrence in cancer. This type of O-linked glycosylation is not limited to mucins but can occur on many cell surface glycoproteins where only a small number of sites may be present. Upon EGF ligation, EGFR induces a signaling cascade but can also translocate to the nucleus where it can directly regulate gene transcription. Here we show that upon EGF binding, human breast cancer cells carrying different O-linked glycans respond by transcribing different gene expression signatures. This is not a result of changes in signal transduction but due to the differential nuclear translocation of EGFR in the two glyco-phenotypes. This is regulated by the formation of an EGFR/galectin-3/MUC1/β-catenin complex at the cell surface that is present in cells carrying short core-1-based O-glycans characteristic of tumour cells but absent in core-2-carrying cells.
An asymptotic analysis for detailed mathematical modeling of counter-flow non-premixed multi-zone laminar flames fueled by lycopodium particles
Authors: Bidabadi Mehdi , Sadeghi Sadegh , Panahifar Pedram , Toghraie Davood , Rahbari Alireza 
Published: July 2019

Purpose
This study aims to present a basic mathematical model for investigating the structure of counter-flow non-premixed laminar flames propagating through uniformly-distributed organic fuel particles considering preheat, drying, vaporization, reaction and oxidizer zones.

Design/methodology/approach
Lycopodium particles and air are taken as biofuel and oxidizer, respectively. Dimensionalized and non-dimensionalized forms of mass and energy conservation equations are derived for each zone taking into account proper boundary and jump conditions. Subsequently, to solve the governing equations, an asymptotic method is used. For validation purpose, results achieved from the present analysis are compared with reliable data reported in the literature under certain conditions.

Findings
With regard to the comparisons, although different complex non-homogeneous differential equations are solved in this paper, acceptable agreements are observed. Finally, the impacts of significant parameters including fuel and oxidizer Lewis numbers, equivalence ratio, mass particle concentration, fuel and oxidizer mass fractions and lycopodium initial temperature on the flame temperature, flame front position and flow strain rate are elaborately explained.

Originality/value
An asymptotic method for mathematical modeling of counter-flow non-premixed multi-zone laminar flames propagating through lycopodium particles.
Numerical study of unsteady boundary layer flow and heat transmission of a nano-fluid past a continuously stretching sheet immersed in porous media
Authors: Haider Sajjad , Syed Muhammad Imran , Li Yun-Zhang , Butt Adnan Saeed 
Published: July 2019

Purpose
This paper aims to incorporate a numerical investigation of unsteady flow of nano-fluid near the boundary wall and heat transmission over a flat sheet in porous media under the assumption that sheet is continuously stretching. A comprehensive study is accomplished to probe the impacts of different physical parameters on heat transmission and fluid flow.

Design/methodology/approach
The problem is designed mathematically by using Navier–Stokes equations and corresponding equations are transmuted into non-dimensional form, which are reduced to local non-similarity equations. Implicit finite difference scheme is used to attain a non-similar solution for values of similarity variable ranging in [0,1]

Findings
The reduced Nusselt number is a decreasing function of each dimensionless number, while the reduced Sherwood number is an increasing function of each considered value of parameters Pr, Sc, Nb and Nt.

Originality value
Motivated by the industrial, technological and scientific importance, the objective of this study is to discuss the unsteady flow generated by linear stretching of the surface in Nano-fluid in a porous medium. However, the investigation of unsteady boundary layer flow and heat transfer of a Nano-fluid past a stretching surface immersed in a porous medium has not been discussed yet. Furthermore, finite difference scheme is used to solve the problem, and authenticate results are achieved which are in good agreement with published work.
Lesson study with music: a new way to expand the dialogic space of learning and teaching
Authors: Gruber Hubert 
Published: July 2019

PurposeThe purpose of this paper is to show that lesson study by including elements from music and music education can sustainably expand and improve the dialogical space for teaching and learning in higher education, especially for primary and secondary teacher education students.Design/methodology/approachFor the first time under the topic “Lesson Study: Music in Dialogue,” corresponding study programs were prepared at the University College of Teacher Education, Lower Austria. The data material from which answers to research questions can be generated are the “Didactic Design Pattern” and classical research lesson planning, observation and discussion instruments. Moreover, discussion protocols of the reflection meetings offered insights the participants gained through sharing their experience of a series of lesson study cycles including focussed collaboration between mentors, teachers, teacher education students and primary school pupils.FindingsWithin the lesson study groups, the space for cooperation and dialogue widened considerably and the interest in the work and expertise of each other increased. Based on the principles of a “community of practice,” this study shows the positive effects of professional collaboration on primary and secondary teacher education students and a lasting impact on their pupils’ learning. Thereby, the dialogical principle was found to play a central and important role. In connection with music- and art-related processes, previous limitations in teaching and learning with music can be exceeded for pupils, teacher education students and teachers.Research limitations/implicationsThis study, therefore, provides new insights into questions of organization and implementation, as well as scientific and didactic support in professional learning communities.Originality/valueSo far, there has been little practitioner research through lesson study in the field of music education. In particular, lesson study enhancing the cooperation between music education and other subject areas through dialogical-integrative work has brought about knowledge and insights of great importance for the further development of an appropriate didactic approach in dialogic music education.
Cues for shaping purchase of local retail apparel clothing brands in an emerging economy
Authors: Zebal Mostaque A. , Jackson Faye Hall 
Published: July 2019

Purpose
The purpose of this paper is to explore and identify the cues that shape the purchase of local retail apparel clothing brands in an emerging economy. The study further develops a conceptual framework for the cues that shape the purchase of local retail apparel clothing brands.

Design/methodology/approach
A focus group methodology is used for data collection from the local retail clothing consumers in Bangladesh. Data collected for this study were coded and categorized using inductive reasoning methods and similar responses were identified from a prepared data matrix. The results were presented in narrative while preserving the authenticity of participant response.

Findings
Three cues were identified that shape the purchase of local retail apparel clothing brands in Bangladesh. First, consumers buy local retail apparel clothing brands due to the product authenticity (product quality, product uniqueness, apparel fittings, apparel durability, color combination, attractive design, comfortability and reasonable price). Second, consumer cosmopolitanism (urbanization of people, migration and overseas travel, and access to cable television and international channels) positively related to the purchase of local retail apparel brands in Bangladesh. Third, consumer ethnocentrism (superiority of local made brands over imported foreign brands, moral obligation for purchasing local products and patriotism) is a contributory cue responsible for the success of local retail apparel clothing brands in Bangladesh.

Originality/value
This study is a first of its kind to significantly enrich the consumer behavior literature related to local retail apparel branded companies and their implications.
Glocalising university websites: culturally formatted Arab sentiments
Authors: Vadakepat Vanaja Menon , Menon Devaki Vadakepat 
Published: July 2019

Purpose
Many researchers have addressed students as consumers and considered their online searches to choose a university as typical buying behaviour. The myriad features of digital information enable universities to conveniently and quickly reach educational markets at a relatively low cost. Consumers’ market choices can usefully be interpreted in terms of their cultural perceptions. To encourage Web viewers to make repeat visits to, and remain longer on, their websites, it is critical for international universities to understand local and regional viewers’ perceptions and preferences regarding non-text Web messages through the lens of culture. The purpose of the current study is to address the need for, and the challenge presented by, glocalising the text and non-text aspects of university websites by investigating Arab consumers’ perceptions of these websites.

Design/methodology/approach
The sampling frame comprised 200 residents from the Emirate of Abu Dhabi, including 100 high school students and 100 stakeholders, with equal proportions of Arabs and non-Arabs. Illustrations and images were used in the questionnaire to collect respondents’ perceptions about university websites from a cultural perspective.

Findings
This study identifies a need to glocalise the non-text and website messages of international universities that are aiming to penetrate educational markets in the Emirates.

Research limitations/implications
This study clearly identifies the segment that is most receptive to a “glocalised” website communication strategy of international universities: Arab students, aged 16 or above, and educated stakeholders, expect to view academic information on websites, as do viewers everywhere, but prefer this information to reflect the values and traditions of Arab culture.

Originality/value
The increasing inflow of students from the Gulf region to the United Arab Emirates, instead of their usual choice of European or Western educational destinations, has motivated international universities to envisage the Emirates as a location for their campus expansions. An understanding of the approaches of Arab viewers to the websites of international universities through the lens of culture is essential for bridging the literature gaps that currently persist in the area of digital promotion and social marketing.
Breadth and frequency of marketing metric reporting and firm performance in the Middle East
Authors: Sailors John J. 
Published: July 2019

Purpose
The purpose of this paper is to explore a host of issues related to the use of marketing metrics and firm performance in the context of the Middle East. Specifically, it seeks to explore which marketing metrics relate to perceived performance, to understand how frequency of metric reporting impacts perceived performance, to identify the impact that marketing dashboards have on perceived firm performance and to analyze how measurement ability relates to perceived performance.

Design/methodology/approach
This paper used an online survey administered to marketing managers at firms located in the Middle East. A total of 55 participants provided usable data. Participants provided the frequency at which 71 different marketing metrics are reported by their firms and their assessments of the firm’s performance with respect to sales growth, market share growth, and profitability. In addition, they indicated whether or not a marketing dashboard was used to report these metrics, and if so, how long ago the dashboard had been implemented. They also assessed their firm’s holistic ability to measure and use metrics compared to their competition.

Findings
As expected, marketers in the Middle East found the marketing metrics examined to vary in their usefulness as judged by their relationship to perceived performance. For those metrics that were perceived to be useful, their utility tended to peak at a moderate level of reporting frequency. These findings also varied by the type of performance considered. The use a marketing metric dashboard did not relate to perceived performance, but the frequency with which the dashboards were reported was found to have a negative linear relationship to perceived performance. Overall, the more capable respondents judged their firms to be with respect to measuring and reporting metrics, the higher their perceived performance.

Practical implications
This paper offers new insights into the usefulness of a wide variety of marketing metrics to marketers in the Middle East. It also provides guidance on the ideal reporting frequency for those metrics. The findings suggest that marketers in the Middle East should focus on reporting key metrics at an appropriate frequency, regardless of whether or not a dashboard format is used. If a dashboard is used, the results of this paper suggest that care should be taken that it not be reported too frequently.

Originality/value
This paper contributes to our understanding of how marketing metrics relate to performance. As the first such study undertaken in the context of Middle Eastern marketers, it represents an important replication and extension of previous findings in other contexts.
