A new triple molybdate, Rb2Ag1+3x
In1–x
(MoO4)3 (0 ≤ x ≤ 0.02), was found in the course of a study of the system Rb2MoO4–Ag2MoO4–In2(MoO4)3 and was synthesized as both powders and single crystals by solid-state reactions and spontaneous crystallization from melts. The structure of Rb2Ag1+3x
In1–x
(MoO4)3 (x ≈ 0.004) is of a new type crystallizing in the centrosymmetric space group R\overline{3}c [a = 10.3982 (9), c = 38.858 (4) Å, Z = 12 and R = 0.0225] and contains (In,Ag)O6 octahedra and distorted Ag1O6 trigonal prisms linked by common faces to form [Ag(In,Ag)O9] dimers connected to each other via MoO4 tetrahedra into an open three-dimensional (3D) framework. Between two adjacent [Ag(In,Ag)O9] dimers along the c axis, an extra Ag2O6 trigonal prism with about 1% occupancy was found. The Ag1O6 and Ag2O6 prisms are located at levels of z ≈ 1/12, 1/4, 5/12, 7/12, 3/4 and 11/12, and can facilitate two-dimensional ionic conductivity. The 12-coordinate Rb atoms are in the framework cavities. The structure of Rb2AgIn(MoO4)3 is a member of the series of rhombohedral 3D framework molybdate structure types with a ≈ 9–10 Å and long c axes, which contain rods of face-shared filled and empty coordination polyhedra around threefold axes. Electrical conductivity of ceramics is measured by impedance spectroscopy. Rb2AgIn(MoO4)3 undergoes a `blurred' first-order phase transition at 535 K with increasing electrical conductivity up to 1.1 × 10−2 S cm−1 at 720 K. Thus, the compound may be of interest for developing new materials with high ionic conductivity at elevated temperatures.
Increasing diversity, awareness, and inclusion in corporate culture: investigating communities of practice and resource groups among employees
Authors: Dutton Kelly 
Published: November 2018

Purpose
This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

Design/methodology/approach
This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

Findings
Diversity is increasing and there are huge benefits to organizations in supporting this, both for their employees and their customer base. A means of providing support to employees is the creation of employee resource groups (ERGs) which provide a safe community to discuss issues, have a voice, increase visibility, and receive learning and development opportunities, both formally and informally. ERGs can raise awareness throughout the organization to non-members and business leaders alike, reducing stereotypical thinking and increasing integration. This has wider benefits in terms of reducing employee turnover and creating an inclusive, productive workforce.

Practical implications
The paper provides strategic insights and practical thinking that have influenced some of the world's leading organizations.

Originality/value
The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information, and presenting it in a condensed and easy-to-digest format.
Managing mining project documentation using human language technology
Authors: Tomašević Aleksandra , Stanković Ranka , Utvić Miloš , Obradović Ivan , Kolonja Božo 
Published: November 2018

Purpose
This paper aims to develop a system, which would enable efficient management and exploitation of documentation in electronic form, related to mining projects, with information retrieval and information extraction (IE) features, using various language resources and natural language processing.

Design/methodology/approach
The system is designed to integrate textual, lexical, semantic and terminological resources, enabling advanced document search and extraction of information. These resources are integrated with a set of Web services and applications, for different user profiles and use-cases.

Findings
The use of the system is illustrated by examples demonstrating keyword search supported by Web query expansion services, search based on regular expressions, corpus search based on local grammars, followed by extraction of information based on this search and finally, search with lexical masks using domain and semantic markers.

Originality/value
The presented system is the first software solution for implementation of human language technology in management of documentation from the mining engineering domain, but it is also applicable to other engineering and non-engineering domains. The system is independent of the type of alphabet (Cyrillic and Latin), which makes it applicable to other languages of the Balkan region related to Serbian, and its support for morphological dictionaries can be applied in most morphologically complex languages, such as Slavic languages. Significant search improvements and the efficiency of IE are based on semantic networks and terminology dictionaries, with the support of local grammars.
Fred Harvey and the Harvey girls
Authors: Ford Robert C. , Van Fleet David D. 
Published: November 2018

Purpose
The purpose of this paper is to examine the management innovations developed and implemented by the Harvey House restaurants with specific attention to those human resource policies and procedures that were created to use what many believe to be the first large-scale use of single women working away from home, the famous Harvey Girls. A second purpose of this paper is to use bricolage theory to frame the innovations that Harvey pioneered to illustrate how the theory pertains to this entrepreneur who civilized dining in the “Wild West.”

Design/methodology/approach
This paper relies on secondary and archival sources to inform its points and rationale.

Findings
Fred Harvey applied his experience-gained knowledge to invent a system that would provide meals to railroad travelers along the Atchison, Topeka and Santa Fe railroad that were not only consistently excellent and reasonably priced but also could be served within the tight time limits of train stops for fuel and water. The precision of his service standards was innovative and required trained and disciplined servers. To deliver the quality of service for which his company became known across the “Wild West.” Harvey invented his famous Harvey Girls.

Originality/value
Fred Harvey’s invention of the Harvey Girls represents the first large-scale employment of women and required the invention of human resource management policies, procedures and processes. This is the story of how this management innovator successfully applied entrepreneurial bricolage to bring civilized dining to the “Wild West.”
Place–brand stereotypes: does stereotype-consistent messaging matter?
Authors: Bauer Brittney C. , Johnson Clark D. , Singh Nitish 
Published: November 2018

PurposeThe purpose of this paper is to address an overarching question: Does matching consumer place–brand associations with stereotype-consistent messaging affect consumer perceptions of an advertisement?Design/methodology/approachThis paper presents two experiments that examine participants’ differing evaluations of advertisements under various experimental conditions. Study 1 examines the match of place–brand warmth versus competence stereotypes and the use of symbolic versus utilitarian advertising messaging for both new foreign and domestic brands. Study 2 examines this match for global brands.FindingsThe paper reveals that stereotype-consistent messaging increases the perceived fit between the advertisement and the brand for new foreign brands but not for new domestic or global brands. Furthermore, in a post-hoc analysis, this congruence is found to improve attitude towards the brand, purchase intentions and brand response, through the mediating effect of attitude towards the ad.Originality/valuePlace–brand stereotypes impact consumer attitudes and opinions regarding brands from different countries. This paper applies two universal social judgment dimensions from social psychology—warmth and competence—to the novel context of advertising messaging to examine previously unexplored facets of the place–brand image.
A corpus of debunked and verified user-generated videos
Authors: Papadopoulou Olga , Zampoglou Markos , Papadopoulos Symeon , Kompatsiaris Ioannis 
Published: November 2018

Purpose
As user-generated content (UGC) is entering the news cycle alongside content captured by news professionals, it is important to detect misleading content as early as possible and avoid disseminating it. The purpose of this paper is to present an annotated dataset of 380 user-generated videos (UGVs), 200 debunked and 180 verified, along with 5,195 near-duplicate reposted versions of them, and a set of automatic verification experiments aimed to serve as a baseline for future comparisons.

Design/methodology/approach
The dataset was formed using a systematic process combining text search and near-duplicate video retrieval, followed by manual annotation using a set of journalism-inspired guidelines. Following the formation of the dataset, the automatic verification step was carried out using machine learning over a set of well-established features.

Findings
Analysis of the dataset shows distinctive patterns in the spread of verified vs debunked videos, and the application of state-of-the-art machine learning models shows that the dataset poses a particularly challenging problem to automatic methods.

Research limitations/implications
Practical limitations constrained the current collection to three platforms: YouTube, Facebook and Twitter. Furthermore, there exists a wealth of information that can be drawn from the dataset analysis, which goes beyond the constraints of a single paper. Extension to other platforms and further analysis will be the object of subsequent research.

Practical implications
The dataset analysis indicates directions for future automatic video verification algorithms, and the dataset itself provides a challenging benchmark.

Social implications
Having a carefully collected and labelled dataset of debunked and verified videos is an important resource both for developing effective disinformation-countering tools and for supporting media literacy activities.

Originality/value
Besides its importance as a unique benchmark for research in automatic verification, the analysis also allows a glimpse into the dissemination patterns of UGC, and possible telltale differences between fake and real content.
What empowers Egyptian women: resources versus social constrains?
Authors: Nazier Hanan , Ramadan Racha 
Published: November 2018

Purpose
This paper aims to tackle an important question related to women’s economic empowerment in highly patriarchal societies like Egypt. The paper discusses individual, household, wealth and location factors determining women empowerment, as measured by two dimensions: decision-making power and mobility.

Design/methodology/approach
Using the “Egypt Labor Market Panel Survey” (ELMPS) 2012, a Multiple Indicators Multiple Causes (MIMIC) model was estimated to study the main economic resources and social constraints that determine women empowerment as measured by the power of women over household decisions and her freedom of movement in Egypt.

Findings
Three key messages could be delivered. First, women’s own economic resources as captured by her employment status are an important source of her empowerment. Second, contrary to theoretical prediction education is not playing its expected role in developing awareness and transforming ideas concerning gender roles in Egypt. Third, the importance of social local context is fundamental for Egyptian women empowerment.

Originality/value
This study is an attempt to address some of the gaps in the literature for the Egyptian case, where there is a lack in rigorous studies measuring women empowerment and examining its determinates. This is done by first, tackling multiple dimension of women’s empowerment, decision-making inside households and freedom of mobility. Second, using MIMIC model, which is a modeling approach that allows for studying the relations between several causes of a given latent variable, such as “Empowerment” in our case, and a number of its possible indicators, without a directly observable measure of the latent variable. Third, using the most recent set of data; the ELMPS 2012 which has a special focus on women’s resources and agency that permits greater content validity of the multidimensional setup. Forth, the macro level differences in women’s status are tackled through using location dummy variables. Finally, given the important correlation between wealth level and women empowerment, the paper is considered a first attempt to analyze such impact by including a variable that captures the wealth level of the woman’s household as one determinant of empowerment.
Intra‐survey reservoir fluctuations – implications for quantitative 4D seismic analysis
Authors: Omofoma Veronica , MacBeth Colin , Amini Hamed 
Published: November 2018

ABSTRACTDuring the time taken for seismic data to be acquired, reservoir pressure may fluctuate as a consequence of field production and operational procedures and fluid fronts may move significantly. These variations prevent accurate quantitative measurement of the reservoir change using 4D seismic data. Modelling studies on the Norne field simulation model using acquisition data from ocean‐bottom seismometer and towed streamer systems indicate that the pre‐stack intra‐survey reservoir fluctuations are important and cannot be neglected. Similarly, the time‐lapse seismic image in the post‐stack domain does not represent a difference between two states of the reservoir at a unique base and monitor time, but is a mixed version of reality that depends on the sequence and timing of seismic shooting. The outcome is a lack of accuracy in the measurement of reservoir changes using the resulting processed and stacked 4D seismic data. Even for perfect spatial repeatability between surveys, a spatially variant noise floor is still anticipated to remain. For our particular North Sea acquisition data, we find that towed streamer data are more affected than the ocean‐bottom seismometer data. We think that this may be typical for towed streamers due to their restricted aperture compared to ocean‐bottom seismometer acquisitions, even for a favourable time sequence of shooting and spatial repeatability. Importantly, the pressure signals on the near and far offset stacks commonly used in quantitative 4D seismic inversion are found to be inconsistent due to the acquisition timestamp. Saturation changes at the boundaries of fluid fronts appear to show a similar inconsistency across sub‐stacks. We recommend that 4D data are shot in a consistent manner to optimize aerial time coverage, and that additionally, the timestamp of the acquisition should be used to optimize pre‐stack quantitative reservoir analysis.
Fencing for wildlife disease control
Authors: Mysterud Atle , Rolandsen Christer M. 
Published: November 2018

Abstract

Fencing is a contentious issue due to its impact on conservation. The Danish government aims to establish a 70 km fence towards the border of Germany and the agricultural ministry of Bulgaria erected 133 km fences along the border with Romania to prevent the spread of African swine fever by wild boar. The Norwegian government recently erected 24 km of fencing as part of combating chronic wasting disease among reindeer. Europe therefore faces a new situation: fencing to limit emerging wildlife diseases. There is, however, surprisingly little scientific literature available on the efficacy of fencing for controlling wildlife disease.

Fencing to combat disease include (a) “perimeter fencing” aiming for containment and reducing likelihood of geographic spread, and (b) “hot spot fencing” aiming to lower transmission rates within endemic disease areas. Critical limitations of perimeter fencing include: numerous practical and construction details, differences in animal behaviour relative to fences, animal contact along fences, placement relative to natural barriers, human infrastructure that disrupt continuous fencing, and mode of disease transmission including human‐aided disease spread.

Hot spot fencing is a potentially important way of reducing transmission of diseases once endemic but materials and construction of fences need to be well thought through. A single fence breach does not have the same consequences as for perimeter fencing.

Synthesis and applications. Fencing as a tactic to mitigate the spread of disease appears appealing to politicians, but implementation uncertainty is considerable. We fear efforts may be futile unless more attention is paid to both practical and biological detail. There is also an urgent need to build a more evidence‐based approach using experience from other sectors.
Seed moisture content as a primary trait regulating the lethal temperature thresholds of seeds
Authors: Tangney Ryan , Merritt David J. , Fontaine Joseph B. , Miller Ben P. 
Published: November 2018

Abstract

Fire has long shaped biological responses of plants and plant communities in many ecosystems; yet, uncontrolled wildfire frequently puts people and infrastructure at risk. Fuel or hazard reduction burning outside of the historic fire season is a common and widespread practice aimed at reducing the risk of high‐severity fires, which ideally also considers biodiversity values. Within fire‐prone systems, seed banks are critical for plant species’ regeneration, and seeds are typically adapted to survive the passage of fire and to regenerate in response to cues associated with historic fire regimes. However, species‐specific tolerances to the heat from fire exist; likely influenced by a range of physical, physiological, and morphological seed traits, which may differ between seasons. The identification of these tolerances and associated seed traits may inform fire and species management.

We determined the lethal temperatures for seeds in relation to their moisture content, and other key traits that we hypothesised may be associated with survival. Seeds from 14 native species and 4 species non‐native to fire‐prone Mediterranean climate Banksia woodlands of south‐west Western Australia were exposed to temperatures between 50 and 180°C for 3 min at three different moisture contents. The temperature at which half the seeds were killed (T50) was estimated using nonlinear modelling. Seed mass, seed shape, embryo type, plant resprouting ability, seed storage syndrome, and native/non‐native status were quantified and modelled for their relationship with T50.

Increased moisture content was a significant predictor of elevated seed mortality. Seeds with higher moisture (95% relative humidity [RH]) content perished at much lower temperatures. Seeds with low moisture content (15% or 50% RH) were able to survive significantly higher temperatures (median increase of 38 and 31°C higher respectively). Seeds with basal embryos showed significantly lower T50 than other embryo types.

Synthesis. Seeds with elevated moisture contents have lower lethal temperature thresholds, leading to increased seed mortality during fire events when seeds (and soils) are moist. Thermal tolerance varied among coexisting species within this fire‐prone system. These data suggest potential concern for the impacts of aseasonal burning practices (i.e., cool/wet season burning), and highlight the importance of taking seed moisture content into account when planning and implementing prescribed burning.
Class and status: on the misconstrual of the conceptual distinction and a neo‐Bourdieusian alternative
Authors: Paalgard Flemmen Magne , Jarness Vegard , Rosenlund Lennart 
Published: November 2018

AbstractIn this article, we address the classical debate about the relationship between the economic and cultural aspects of social stratification, typically cast in terms of Weber’s distinction between class and status. We discuss in particular Chan and Goldthorpe’s influential, yet largely unchallenged, attempt to reinstate a strict version of the class‐status distinction, mounted as an attack on ‘Bourdieusian’ accounts. We argue that this is unconvincing in two respects: There are fundamental problems with their conceptualization of status, producing a peculiar account where one expression of status honour explains the other; in addition, their portrayal of the Bourdieusian approach as one‐dimensional is highly questionable. In contradiction of a reading of Bourdieu as discarding the class‐status distinction, we develop an alternative, neo‐Bourdieusian account that recognizes class and status as distinct aspects of stratification, thereby allowing for a subtle analysis of their empirical entwinement. The fruitfulness of this approach is demonstrated by analysing the homology between the space of lifestyles and the social space through Multiple Correspondence Analysis of unusually rich data about lifestyles. Importantly, we highlight the relative autonomy of these spaces: Although they exhibit a similar structure, they do not overlap completely.

Published: November 2018

ProblemThe influence of fetal sex on immune responses in multifetal pregnancies remains incompletely elucidated. The a2 isoform of vacuolar adenosine triphosphatase (a2V) is expressed on the cell membrane of maternal lymphoid cells and contributes to down‐regulation of pro‐inflammatory immune responses during gestation. The association between fetal sex and a2V expression on peripheral blood mononuclear cells (PBMCs) from mothers with twin gestations was assessed.Method of studyPatients in this prospective study were 93 women with twin pregnancies in their mid‐second or early third trimester—27 with two male, 30 with two female and 36 with one male and one female fetus. PBMCs were isolated and a2V was measured by ELISA in cell lysates. Demographic and clinical data were subsequently obtained and correlations between a2V and fetal sex, birthweight and pregnancy outcome were assessed by the Mann‐Whitney and Spearman rank correlation tests.ResultsThe mean a2V level was highest when both fetuses were male (2.0 ng/mL) and lowest when both were female (1.5 ng/mL; P = 0.0184). Only when both fetuses were female did the a2V concentration negatively correlate with birthweight of the 1st (P = 0.0011) and 2nd (P = 0.0044) born fetus and with gestational age at delivery (P = 0.0018). There were no associations between a2V and these outcomes in male only or mixed twin pregnancies.ConclusionWe conclude that the a2V‐mediated regulation of maternal immunity during twin pregnancies is influenced by fetal sex.
