The dynamics of oil prices, uncertainty measures and unemployment: a time and frequency approach
Authors: Adeosun Opeoluwa Adeniyi , Olayeni Richard O. , Tabash Mosab I. , Anagreh Suhaib 
Published: January 2023

PurposeThis study investigates the nexus between the returns on oil prices (OP) and unemployment (UR) while taking into account the influences of two of the most representative measures of uncertainty, the Baker et al. (2016) and Caldara and Iacovello (2021) indexes of economic policy uncertainty (EP) and geopolitical risks (GP), in the relationship.Design/methodology/approachThe authors use data on the US, Canada, France, Italy, Germany and Japan from January 2000 to February 2022 and the UK from January 2000 to December 2021. The authors then apply the continuous wavelet transform (CWT), wavelet coherence (WC), partial wavelet coherence (PWC) and multiple wavelet coherence (MWC) to examine the returns within a time and frequency framework.FindingsThe CWT tracks the movement and evolution of individual return series with evidence of high variances and heterogenous tendencies across frequencies that also align with critical events such as the GFC and COVID-19 pandemic. The WC reveals the presence of a bidirectional relationship between OP and UR across economies, showing that the two variables affect each other. The authors’ findings establish the predictive influence of oil price on unemployment in line with theory and also show that the variation in UR can impact the economy and alter the dynamics of OP. The authors employ the PWC and MWC to capture the impact of uncertainty indexes in the co-movement of oil price and unemployment in line with the theory of “investment under uncertainty”. Taking into account the common effects of EP and GP, PWC finds that uncertainty measures significantly drive the co-movement of oil prices and unemployment. This result is robust when the authors control for the influence of economic activity (proxied by the GDP) in the co-movement. Furthermore, the MWC reveals the combined intensity, strength and significance of both oil prices and the uncertainty measures in predicting unemployment across countries.Originality/valueThis study investigates the relationship between oil prices, uncertainty measures and unemployment under a time and frequency approach.HighlightsWavelet approaches are used to examine the relationship between oil prices and unemployment in the G7.We account for uncertainty measures in the dynamics of oil prices and unemployment.We observe a bidirectional relationship between oil prices and unemployment.Uncertainty measures significantly drive oil prices and unemployment co-movement.Both oil prices and uncertainty measures significantly drive unemployment.
Worker resistance strategies and union action in platform work: the case of Uber in Spain
Authors: Riesgo Gómez Víctor 
Published: January 2023

PurposeThe author analyses the strategies developed by workers and unions to obtain representation and the successes and limitations of the strategies, in a context of platform work such as Spanish dominated by labour relations of employee workers.Design/methodology/approachThe empirical material is the result of a series of in-depth interviews conducted between August 2020 and September 2021 with 41 workers, 15 of them union delegates, in addition to 4 union members and a labour lawyer. From these interviews, the author obtains a detailed account of the working conditions and the different phases that unionism has gone through in its objective of obtaining representation in a completely new sector.FindingsThe author found that employment in the relationship does not solve all the problems of platform work, especially those related to algorithmic control, but employment in the relationship provides advantages such as the right to representation. Workers play an important role in union strategies.Originality/valueThis study is the first in Spain, where platform work in passenger transport includes the employment relationship as a legal contracting mechanism.
Antecedents and job outcomes from a self-efficacy perspective while working from home among professionals during the COVID-19 pandemic
Authors: Lathabhavan Remya , Griffiths Mark D. 
Published: January 2023

PurposeWorking from home (WFH) was one of the major changes that occurred in many organizations during the COVID-19 pandemic. This also led to online training being conducted during this WFH period. The present study investigated the role of technology, manager support and peer support on self-efficacy and job outcomes (i.e. training transfer, work engagement and job satisfaction) of employees while WFH.Design/methodology/approachThe study framework incorporated Bandura's self-efficacy theory. Data were collected from 852 employees in India, and structural equation modeling was used to analyze the data.FindingsThe study found positive relationships between ease of technology use, manager support and peer support on self-efficacy and a negative relationship between self-efficacy and technostress. The study also found significant positive relationships between self-efficacy and training transfer, work engagement and job satisfaction. Moreover, the study also identified the moderating effects of WFH and technical issues in the relationships of self-efficacy with training transfer, work engagement and job satisfaction.Originality/valueThe study is novel in that it extended self-efficacy theory regarding the WFH context with influencers such as technology, managers and peers as organizational factors. It also demonstrated the effectiveness of remote working and online training considering the potential antecedents while WFH. Moreover, the study highlighted the simultaneous role of technology and people (managers and peers) in enhancing job outcomes by increasing self-efficacy among employees.
Alternative certification system for supply chain sustainability: how stakeholder alignment affects institutionalization
Authors: Liu Chia-Yi 
Published: January 2023

PurposeThis study expands the isomorphic logic on the participatory guarantee system (PGS) alternative certification method, which aims to level the supply chain sustainability field to determine how the alignment of disadvantaged agrifood stakeholders (e.g. small/applicant farmers, local organizations, consumers and volunteer auditors) might neutralize the negative effects of stakeholder heterogeneity (SH) on PGS recognition.Design/methodology/approachThe sample comprised 113 multilateral matching questionnaires collected from disadvantaged agrifood stakeholders participating in the PGS activities of the Green Conservation Label managed by Taiwan's Tse-Xin Organic Agriculture Foundation (TOAF). This study adopted hierarchical regression to test the hypotheses.FindingsStakeholder alignment, external community (EC) constructs, similar backgrounds (SBs) and value congruence (VC) diminish the negative effects of SH on PGS recognition.Social implicationsPGS is an agrifood supply chain social movement designed to allow underprivileged actors to enact solutions collectively to address social inequities and ecological problems through fair procedures, collective assignments and collaborative intentionality. PGS members who leverage VC, SB and EC will have a greater chance of successfully overcoming their institutional disadvantages.Originality/valueBased on the PGS activities initiated by disadvantaged agrifood stakeholders, this study transformed isomorphic logics, including coercive, mimetic and normative isomorphisms, into a mechanism with which individuals can build a governance structure that helps disadvantaged agrifood stakeholders develop alternative institutions by pooling their resources.
Compliance issues in arbitration proceedings – bribery, money laundering and other abuses
Authors: Teichmann Fabian , Boticiu Sonia Ruxandra , Sergi Bruno S. 
Published: January 2023

Purpose
The purpose of this study is to provide a firsthand perspective on the challenges and risks that can arise in arbitration proceedings.

Design/methodology/approach
To investigate the concrete methods money launderers use, a qualitative study was conducted with 10 alleged money launderers and 18 prevention experts. The results were then tested quantitatively, and it was concluded that among money launderers, the highly regulated financial sector is less popular than other sectors.

Findings
Money launderers relocate to unregulated sectors or offshore banks to avoid being questioned by compliance officers. Therefore, it is necessary for arbitrators involved in commercial or investor–state arbitration to have the expertise to readily identify the issues raised by these criminal law concepts and provide answers.

Originality/value
This paper examines the intersection between the areas of international commercial arbitration and money laundering, bribery, as well as embezzlement. At the same time, it draws attention to the need to analyze compliance issues in arbitration proceedings.

Published: January 2023

PurposeFollowing a bibliometric approach, this study examines research on brand and branding in family businesses (FBs) to identify influential sources and main areas of knowledge, proposes an integrative framework that provides a holistic perspective of this field with an interdisciplinary cross-fertilization view and explores new avenues for future research and practice.Design/methodology/approachBased on 449 bibliographic references retrieved from the Web of Science database through a systematic process, the authors employed bibliographic coupling analysis to visualize the relationships among key works in the field and subsequently performed a literature review to deepen the analysis.FindingsThe bibliographic coupling analysis structured the existing research into six thematic clusters. Four of them follow an internal perspective and focus on FB identity and its influence on the construction of corporate brand identity, whereas the other two follow an external perspective that explores how FB brands are communicated and perceived by stakeholders and the influence of corporate brands and branding on FB image and reputation. Drawing from an in-depth review of the literature, this study offers a novel integrative framework, together with a set of proposals with managerial and theoretical implications.Practical implicationsThe proposed framework aims to clarify the relationship between internal identity and management to build and communicate a FB brand. The study also shows the symbiosis that exists among family values, corporate reputation, brand equity and awareness in FBs. The existing interconnection between the family and business generates unique associations that are difficult to imitate.Originality/valueThis study is the first documented attempt at a bibliometric analysis of brands and branding in FBs, which serves to clarify the linkages between different research streams and connecting marketing, organization and FB literature to guide future research. Moreover, the integrative framework provides researchers and practitioners with a better understanding of its scope, highlighting the importance of corporate brand strategies beyond the boundaries of marketing departments.
Sandy seeds: Armour or invisibility cloak? Mucilage‐bound sand physically protects seeds from rodents and invertebrates

Published: January 2023

Abstract

Seeds represent a stage of a plant's life cycle that is extremely vulnerable to predation, which unlike most vegetative herbivory, is fatal to the individual. As such, understanding the distribution and abundance of plants may rely on understanding seed defences: characteristics that make seeds more difficult for granivores to locate, less beneficial for granivores to consume or both.

Seeds that produce mucilage are widespread, found across many families and species. Although short‐term (single day) studies indicate that mucilage may be a fundamental seed defence found throughout the plant kingdom, it is not clear to what extent mucilage provides long‐term benefits to seeds by reducing granivory. Moreover, it is not clear whether this long‐term defence occurs because mucilage reduces seed apparency as substrate‐coated seeds are more difficult to detect, whether substrate‐coated seeds are less valuable or both.

In the first field experiment, we factorially manipulated sand coatings, background sand colour and granivore community using feeding depots to test the mechanistic basis of mucilage‐bound sand as a seed defence against diverse granivores. We found that the sand coating significantly extended chances of seeds remaining over the 101‐day trial, during which rodents were the primary granivores, and our coloration manipulation suggests that the effect was almost entirely physical. We found that whether a seed's sand coating matched its background did not greatly affect chance of removal, leaving the crypsis mechanism unsupported.

We conducted a follow‐up field experiment to test the background‐matching hypothesis in more detail, using 20 sand colours and two colours of flax seeds. We again found no support for crypsis, corroborating the finding that mucilage‐bound sand provides a primarily physical defensive benefit.

Synthesis. The totality of the results from this and previous studies across granivore taxa and plant species suggests that seed mucilage is a widespread and highly effective physical defence employed by many plants against diverse granivores in many environments
Effects of hydrological change in fire‐prone wetland vegetation: An empirical simulation
Authors: Mason Tanya J. , Popovic Gordana C. , McGillycuddy Maeve , Keith David A. 
Published: January 2023

Abstract

Upland swamps are peat‐accumulating, groundwater‐dependent and fire‐prone wetland ecosystems. Drying caused by anthropogenic processes such as underground mining, ditching and climate change may disrupt surface and groundwater flows and result in bottom‐up controls on wetland expression. Fire is an endogenous, recurring disturbance that drives a top‐down consumptive force in many upland swamp systems. When compounded with drying, fire may facilitate permanent community transitions. A dearth of ecological data and temporal lags have hampered our ability to predict risks associated with multiple disturbances in wetland plant communities.

We collected intact wetland mesocosms from valley floors and lower slopes of four undisturbed swamp sites. We transferred the mesocosms to a glasshouse and established three different soil moisture availability levels to simulate wetland drainage. After 20 months of the hydrological treatment, we simulated a fire event by sequentially applying biomass removal (clipping), heat and smoke to half of the mesocosms. We monitored species biomass, richness and composition over a 3.5‐year time frame.

We found evidence of a temporal lag in biomass response to low water availability and synergistic hydrological and fire effects on species richness. In unburnt conditions, richness declined with low water availability but was maintained under high and medium water availability. After simulated fire under medium water availability, however, richness also declined and converged with depauperate low‐water mesocosm richness. Representation by many obligate swamp species declined in low compared with high water availability mesocosms over time, an effect that was amplified by the fire treatment.

Synthesis. Our evidence of lagged effects of hydrological change on wetland vegetation and compounding effects of fire should be considered in impact assessments, monitoring programs and ecosystem management to avoid irreversible wetland change in drying environments.
The differences between actions and desires: The role of religious congregations in national crises and disasters
Authors: Lundgren Linnea , Fransson Sara 
Published: January 2023

AbstractDuring the last few decades in the handling of ongoing crises and preparing for future crises, governments and other public authorities increasingly emphasize the important role religious organizations can play in crises and disaster management. Considering this development, it is appropriate to ask whether the expectations by policymakers are mirrored by the religious organizations themselves? This article aims to answers this question by studying both the organizations' desired role in time of national crises and disasters and the actual role taken by local congregations in Sweden during the Covid‐19 pandemic. It also aims to study whether this differs in relation to organizational differences and religious affiliation. The study clearly shows that 8 out of 10 congregations believe they have an important role to play in the event of a disaster or crisis. However, despite the high level of willingness, the role congregations take may not always mirror the governments expectations. In terms of differences between congregations, although cross‐religious differences are noted, the size of the organization is the critical factor. The article concludes by discussing the disparity between policymakers' expectations and the willingness of organizations as well as the complexity of policymakers assuming that non‐profit organizations will help unequivocally.
Uterine‐preserving treatments or hysterectomy reintervention after myomectomy or uterine artery embolisation: A retrospective cohort study of long‐term outcomes
Authors: Amoah Alison , Quinn Stephen D. 
Published: January 2023

AbstractObjectiveTo assess comparative rates of further uterine‐preserving procedures (UPP) or hysterectomy reintervention, after myomectomy or uterine artery embolisation (UAE).DesignPopulation‐based, retrospective cohort study.SettingEngland.PopulationWomen who underwent myomectomy or UAE between 2010 and 2015 under the NHS.MethodsData was abstracted from NHS Health Episode Statistics datasets. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using Cox proportional‐hazards regression.Main Outcomes Measures30‐day readmission, UPP and hysterectomy reintervention rates.Results9443 and 6224 women underwent elective myomectomy or UAE, respectively. After 118 136 total person‐years of follow‐up, the rate of hysterectomy was 8.34 and 20.98 per 1000 patient years for myomectomy or UAE, respectively. There was a 2.4‐fold increased risk of undergoing hysterectomy after UAE when compared with myomectomy in adjusted models (HR 2.38 [95% CI 2.10–2.66]) [adjusted for age, ethnicity, multiple deprivation index, geographical region and comorbidities]. The HR for undergoing a UPP reintervention was 1.44 (95% CI 1.29–1.60) in favour of myomectomy. The rate of hysterectomy was increased 22% following UAE compared with laparoscopic myomectomy (0.97–1.52). Age may influence reintervention rates, and there was variation in hysterectomy risk when stratified by geographical region.ConclusionsAfter a median of 7 years of follow‐up, there is a 2.4‐fold increased rate of hysterectomy and 44% increased risk of UPPs as reintervention after UAE, relative to myomectomy. These findings will aid pre‐procedure counselling for women with fibroids. Future work should investigate the effect of other outcome modifiers, such as fertility intentions and fibroid anatomical characteristics.
Effects of rice protein, soy isolate protein, and whey concentrate protein on the digestibility and physicochemical properties of extruded rice starch

AbstractProtein, as the second major component in starchy foods, is crucial for its influence on the physicochemical properties and digestibility of starch. However, the effect of different sources of protein on starch digestibility is still unclear. In this paper, the effects of different sources of proteins (rice protein: RP, soybean isolate protein: SPI, and whey concentrate protein: WPC) on structural features, digestibility, and enzyme activity of extruded rice starch were investigated. The addition of all three proteins reduced the starch digestibility of extrudates. Native SPI and WPC suppressed amyloglucosidase activity, and all three proteins exhibited stronger amyloglucosidase inhibition when hydrolyzed. The rheological properties and Fourier transform infrared spectroscopy results revealed the exogenous proteins and starch interacted through non‐covalent bonds and improved the ordered structures in the extrudates. The extrusion process also facilitated the formation of a V‐type structure. The sum of SDS and RS content of extrudates was negatively correlated with the content of leached amylose and positively correlated with the ratio of 1047/1022 cm−1. These findings suggest that the inclusion of exogenous proteins during extrusion can affect starch digestibility through mechanisms such as the interaction with starch molecules, as well as the inhibition of amylase activity.Practical ApplicationThis result indicated that the addition of protein during extrusion not only increased the nutritional value of the extrudate, but also decreased the starch digestibility. Extrusion technology can efficiently produce extruded products with protein, expanding further applications of protein in food and providing new healthy staple food options for special populations, such as diabetic and overweight people.

Published: January 2023

AbstractRNA sequencing (RNA‐Seq) is popular for measuring gene expression in non‐model organisms, including wild populations. While RNA‐Seq can detect gene expression variation among wild‐caught individuals and yield important insights into biological function, sampling methods can also affect gene expression estimates. We examined the influence of multiple technical variables on estimated gene expression in a non‐model fish, the westslope cutthroat trout (Oncorhynchus clarkii lewisi), using two RNA‐Seq library types: 3′ RNA‐Seq (QuantSeq) and whole mRNA‐Seq (NEB). We evaluated effects of dip netting versus electrofishing, and of harvesting tissue immediately versus 5 min after euthanasia on estimated gene expression in blood, gill, and muscle. We found no significant differences in gene expression between sampling methods or tissue collection times with either library type. When library types were compared using the same blood samples, 58% of genes detected by both NEB and QuantSeq showed significantly different expression between library types, and NEB detected 31% more genes than QuantSeq. Although the two library types recovered different numbers of genes and expression levels, results with NEB and QuantSeq were consistent in that neither library type showed differences in gene expression between sampling methods and tissue harvesting times. Our study suggests that researchers can safely rely on different fish sampling strategies in the field. In addition, while QuantSeq is more cost effective, NEB detects more expressed genes. Therefore, when it is crucial to detect as many genes as possible (especially low expressed genes), when alternative splicing is of interest, or when working with an organism lacking good genomic resources, whole mRNA‐Seq is more powerful.
