AbstractHaplodiploidy and paternal genome elimination (HD/PGE) are common in invertebrates, having evolved at least two dozen times, all from male heterogamety (i.e., systems with X chromosomes). However, why X chromosomes are important for the evolution of HD/PGE remains debated. The Haploid Viability Hypothesis posits that X-linked genes promote the evolution of male haploidy by facilitating purging recessive deleterious mutations. The Intragenomic Conflict Hypothesis holds that conflict between genes drives genetic system turnover; under this model, X-linked genes could promote the evolution of male haploidy due to conflicts with autosomes over sex ratios and genetic transmission. We studied lineages where we can distinguish these hypotheses: species with germline PGE that retain an XX/X0 sex determination system (gPGE+X). Because evolving PGE in these cases involves changes in transmission without increases in male hemizygosity, a high degree of X linkage in these systems is predicted by the Intragenomic Conflict Hypothesis but not the Haploid Viability Hypothesis. To quantify the degree of X linkage, we sequenced and compared 7 gPGE+X species’ genomes with 11 related species with typical XX/XY or XX/X0 genetic systems, representing three transitions to gPGE. We find highly increased X linkage in both modern and ancestral genomes of gPGE+X species compared to non-gPGE relatives, and recover a significant positive correlation between percent X linkage and the evolution of gPGE. These are among the first empirical results suggesting a role for intragenomic conflict in the evolution of novel genetic systems like HD/PGE.Significance StatementSex determination systems such as haplodiploidy, in which males’ gene transmission is haploid, are surprisingly common, however, the evolutionary paths to these systems are poorly understood. X chromosomes may play a particularly important role, either by increasing survival of males with only maternal genomes, or due to conflicts between X-chromosomal and autosomal genes. We studied X-chromosome gene richness in three arthropod lineages in which males are diploid as adults but only transmit their maternally-inherited haploid genome. We find that species with such atypical systems have far more X chromosomal genes than related diploid species. These results suggest that conflict between genetic elements within the genome drives the evolution of unusual sex determination systems.

AbstractA validated method for B vitamin separation and quantification from lentil seeds using ultra-performance liquid chromatography-selected reaction monitoring mass spectrometry (UPLC-SRM MS) was reported. The use of three enzymes (acid phosphatase, β-glucosidase, and rat serum) with a 4 h incubation was sufficient to convert bound B vitamins into their free forms. Twenty B vitamers were selected and a 5-min UPLC-SRM MS method was optimized for rapid analysis. This method was applied to quantify B vitamin concentration during lentil seed germination over a 5-day period. Total B vitamins increased up to 1.5-fold on day 5 (from 39.2 µg/g to 60.6 µg/g of dry weight) comparing with dry seeds. Vitamin B5 (pantothenic acid) was the most abundant B vitamin in both dry seeds (34.2%) and in germinated seeds (17.7%-24.5% of total B vitamins); B8 (biotin) and B12 (cyanocobalamin) were not detected in lentil samples.
Food networks and urban informality in Mumbai, India
Authors: Kotval-K Zeenat 
Published: October 2020

PurposeTraditionally, urban informality has been discussed in terms of housing and markets, usually along the periphery of urban areas where there is disinvestment and decline. This article looks at urban informality through the lens of informal fresh food retail throughout the city of Mumbai, India. In India, fresh produce has traditionally been sold in informal street markets comprising vendors that operate through carts and make-shift stalls set-up on the streets. This article aims to assess the conditions surrounding fresh produce retail that fuel its informality.Design/methodology/approachThis study uses a mixed methods approach by spatially analyzing the location of informal fresh food vendors in ArcGIS, developing a qualitative analysis of the level of proliferation of this network through interviews conducted with vendors and conducting surveys of residents' access patterns and purchasing habits for fresh produce in the city.FindingsResults from this study indicate that the role of density, transportation systems, domestic/household structure, cultural traditions and a bureaucratic system rife with its own challenges have resulted in a distinct infrastructure of food retail networks that has harvested forms of inequalities and injustices that inherently fuel this informal economy.Originality/valueThere is no published study to date that has been done to spatially assess the informal food network in any dense city in India, let alone Mumbai to date. Urban informality, by its nature, is hard to capture, and yet this study takes a holistic view of the food systems in Mumbai, by addressing the location, supply (through vendor interviews) and demand factors (through resident surveys).
Organizational change as tension management: a grounded theory
Authors: Ghiringhelli Cristiano , Virili Francesco 
Published: October 2020

PurposeImplementing automatic sorting operations in the parcel delivery industry can dramatically improve both capacity and service quality but demands radical and complex organizational change. The present in-depth grounded theory study examined a change process of this kind within one of the few global companies in the parcel delivery sector, focusing on three European hubs where automatic sorting had recently been introduced.Design/methodology/approachGrounded theory methodology, which facilitates the gradual emergence and dialogical interpretation of empirically grounded theoretical concepts, was particularly suited to the current project's open-ended research design and the hybrid (prescriptive but also constructive) nature of the change process under study. The investigation comprised iterative cycles of data collection, open coding, selective coding and theoretical coding over a three-year period.FindingsIn keeping with the dual nature of the change underway, a set of tensions were identified between pairs of opposite poles: manual vs automated, planned vs emergent and corporate vs site. The management of these tensions, which leveraged both prescriptive and sensemaking approaches, was found to trigger knowledge production, facilitating a gradual transition from high to low uncertainty and, consequently, progressive movement along the continuum between each pair of competing poles. Within this process, the industrial engineering function acted as an agent of change with a key orchestrating role.Originality/valueAs one of the first in-depth grounded theory analyses of tension management, this study contributes to the relatively recent debate on the recognition, analysis and handling of tensions and paradoxes in organizational change, suggesting innovative criteria for successful change management and identifying promising new avenues for research. From a managerial perspective, the study outcomes suggest that explicit recognition of uncertainty and tensions in organizational change can pave the way for solutions based on agility and continuous organizational learning.
A modified Arrhenius model for as-quenched Al-Mg-Si alloy considering the effect of cooling rate
Authors: Guo Ruichao , Wu Jianjun , Ren Yinxiang 
Published: October 2020

Purpose
Accurate prediction of residual stress requires precise knowledge of the constitutive behavior of as-quenched material. This study aims to model the flow stress behavior for as-quenched Al-Mg-Si alloy.

Design Methodology Approach
In the present work, the flow behavior of as-quenched Al-Mg-Si alloy is studied by the hot compression tests at various temperatures (573–723 K), strain rates (0.1–1 s−1) and cooling rates (1–10 K/s). Flow stress behavior is then experimentally observed, and an Arrhenius model is used to predict the flow behavior. However, due to the fact that materials parameters and activation energy do not remain constant, the Arrhenius model has an unsatisfied prediction for the flow behavior. Considering the effects of temperatures, strain rates and cooling rates on constitutive behavior, a revised Arrhenius model is developed to describe the flow stress behavior.

Findings
The experimental results show that the flow stress increases by the increasing cooling rate, increasing strain state and decreasing temperature. In comparison to the experimental data, the revised Arrhenius model has an excellent prediction for as-quenched Al-Mg-Si alloy.

Originality Value
With the revised Arrhenius model, the flow behaviors at different quenching conditions can be obtained, which is an essential step to the residual stress prediction when the model is implemented in a finite element code, e.g. ABAQUS, in the future.
Numerical simulation of methane spreading in porous media after leaking from an underground pipe
Authors: Wang Ji , Yan Yuting , Li Junming 
Published: October 2020

Purpose
Natural gas leak from underground pipelines could lead to serious damage and global warming, whose spreading in soil should be systematically investigated. This paper aims to propose a three-dimensional numerical model to analyze the methane–air transportation in soil. The results could help understand the diffusion process of natural gas in soil, which is essential for locating leak source and reducing damage after leak accident.

Design/methodology/approach
A numerical model using finite element method is proposed to simulate the methane spreading process in porous media after leaking from an underground pipe. Physical models, including fluids transportation in porous media, water evaporation and heat transfer, are taken into account. The numerical results are compared with experimental data to validate the reliability of the simulation model. The effects of methane leaking direction, non-uniform soil porosity, leaking pressure and convective mass transfer coefficient on ground surface are analyzed.

Findings
The methane mole fraction distribution in soil is significantly affected by the leaking direction. Horizontally and vertically non-uniform soil porosity has a stronger effect. Increasing leaking pressure causes increasing methane mole flux and flow rate on the ground surface.

Originality/value
Most existing gas diffusion models in porous media are for one- or two-dimensional simulation, which is not enough for predicting three-dimensional diffusion process after natural gas leak in soil. The heat transfer between gas and soil was also neglected by most researchers, which is very important for predicting the gas-spreading process affected by the soil moisture variation because of water evaporation. In this paper, a three-dimensional numerical model is proposed to further analyze the methane–air transportation in soil using finite element method, with the presence of water evaporation and heat transfer in soil.

Published: October 2020

Purpose
The purpose of this study is to examine the prevalence and association among school refusal behavior, self-esteem, parental school involvement and aggression in punctual and truant school-going adolescents.

Design/methodology/approach
A purposive sampling technique and cross-sectional design were used in the current study. Participants comprised three heterogeneous sub-groups: school truant students, park truant students and punctual students.

Findings
This study’s findings indicated that father and mother’s school involvement was related to more elevated level of self-esteem for school truant students. Results also indicated that male truant students had more significant probability to school refusal behavior and physical aggression as compared to female truant students. Moreover, results revealed that physical aggression fully mediated among mother’s school involvement, academic self and school refusal behavior in punctual students and school truant students.

Originality/value
There is more need to develop indigenous school-based preventions and interventions aimed at decreasing school truancy in Pakistani context by tackling the predisposing vulnerable factors and supporting and encouraging the protective family and internal factors.

Lecturers could give the students the opportunity to think systematically by beginning by criticizing the interesting contextual problems and ending with meaningful reflection with adequate learning resources.

Originality/value
3CM learning model is a model that is proven to be effective in helping the students in shaping the thinking schemata well and able to improve the creative thinking ability of the students.
Artificial intelligence and the future of work – lessons from the sociology of expectations
Authors: Vicsek Lilla 
Published: October 2020

PurposeWhat is the future of work going to look like? The aim of this paper is to show how the sociology of expectations (SE) – which deals with the power of visions – can make important contributions in terms of thinking about this issue by critically evaluating the dominant expert positions related to the future-of-employment- and artificial intelligence (AI) debate.Design/methodology/approachAfter providing a literature review regarding SE, an approach based on the latter is applied to interpret the dominant ideal-type expert positions in the future of work debate to illustrate the value of this perspective.FindingsDominant future scripts can be characterized by a focus on the effects of AI technology that give agency to technology and to the future, involve the hype of expectations with polarized frames, and obscure uncertainty. It is argued that these expectations can have significant consequences. They contribute to the closing off of alternative pathways to the future by making some conversations possible, while hindering others. In order to advance understanding, more sophisticated theorizing is needed which goes beyond these positions and which takes uncertainty and the mutual shaping of technology and society into account – including the role expectations play.Research limitations/implicationsThe study asserts that the dominant positions contain problematic assumptions. It makes suggestions for helping move beyond these current framings of the debate theoretically. It also argues that scenario building and backcasting are two tools that could help move forward thinking about the future of work – especially if this is done in a way so as to build strongly on SE.Practical implicationsThe arguments presented herein enhance sense-making in relation to the future-of-work debate, and can contribute to policy development.Originality/valueThere is a lack of adequate exploration of the role of visions related to AI and their consequences. This paper attempts to address this gap by applying an SE approach and emphasizing the performative force of visions.

Authors: Pu Xiaodie , Wang Zhengxu , Chan Felix T.S. 
Published: October 2020

PurposeBased on structural embeddedness theory and resource dependence theory, this research aims to examine the mediation role of information sharing in the relationship between deendency structures and electronic supply chain management system (eSCM) adoption and a firm's intention to adopt eSCMs.Design/methodology/approachA survey questionnaire was undertaken from 212 companies based in Mainland China. Three-stage least squares (3SLS) regression was employed to test the research model.FindingsThe results from 3SLS regressions showed that the effect of interdependence on eSCM adoption intention is fully mediated through information sharing when relationship duration is either below or about the mean. Interdependence and dependence disadvantage was shown to have significant positive effects on eSCM adoption while the effect of dependence advantage was statistically insignificant. Relationship duration was found to negatively moderate the relationship between information sharing and adoption intention.Originality/valueThrough investigating factors of inter-organizational relationships, this study fills the knowledge gap in the traditional paradigms which ignore the collaborative nature of eSCM and analyse related problems based on a single firm's point of view.

Findings
The English Government approach to controlling the progress of COVID-19 has been characterised by long-standing tenets of New Public Management that have undermined rather than created trust in their actions.

Originality/value
Originality can be found in the application of existing understandings to the novel situation of seeking to control the COVID-19 pandemic in England.
How gratitude improves relationship marketing outcomes for young consumers
Authors: Fazal-e-Hasan Syed , Mortimer Gary , Lings Ian , Kaur Gurjeet 
Published: October 2020

PurposeRelationship marketing is about developing, maintaining and sustaining mutually beneficial customer–organisation relationships as measured by economic gains. Yet, a purely economic focus does not fully offer a psychological explanation of relationship marketing outcomes. In this regard, this paper has considered gratitude as a significant component of personal relationships, which offers insights into a customer–organisation relationships. Accordingly, this study aims to examine gratitude as a mechanism to predict relationship marketing outcomes, such as overall satisfaction, trust and commitment.Design/methodology/approachData were collected from 1,093 millennial consumers across three university campuses.FindingsResults indicate that gratitude is a mediating mechanism that can explain the relationship between young consumers’ perceptions of relationship marketing investments and overall satisfaction, trust and commitment. Perceived benevolence strengthens the relationship between perceived relationship marketing investments and customer gratitude.Originality/valueThe gratitude model contributes an alternative understanding of how young consumers’ perceptions of an organisation’s marketing investments are important in achieving a high degree of relationship marketing outcomes. This paper further incorporates the moderating roles of customer cynicism and perceptions of benevolence, key individual and relational characteristics, that influence the level of gratitude individuals to experience in response to the investments made by organisations.
