Published: July 2022

ABSTRACTIn order to maintain global food security, it will be necessary to increase yields of the cereal crops that provide most of the calories and protein for the world’s population, which includes common wheat (Triticum aestivum L.). An important factor contributing to wheat yield is the number of grain-holding spikelets which form on the spike during inflorescence development. Characterizing the gene regulatory networks controlling the timing and rate of inflorescence development will facilitate the selection of natural and induced gene variants that contribute to increased spikelet number and yield.In the current study, co-expression and gene regulatory networks were assembled from a temporal wheat spike transcriptome dataset, revealing the dynamic expression profiles associated with the progression from vegetative meristem to terminal spikelet formation. Consensus co-expression networks revealed enrichment of several transcription factor families at specific developmental stages including the sequential activation of different classes of MIKC-MADS box genes. This gene regulatory network highlighted interactions among a small number of regulatory hub genes active during terminal spikelet formation. Finally, the CLAVATA and WUSCHEL gene families were investigated, revealing potential roles for TaCLE13, TaWOX2, and TaWOX7 in wheat meristem development. The hypotheses generated from these datasets and networks further our understanding of wheat inflorescence development.
Somatostatin interneurons in auditory cortex regulate sensory representations and contribute to auditory perception

Published: July 2022

AbstractAs a major class of inhibitory neurons in the mammalian neocortex, somatostatin (SOM)-expressing GABAergic interneurons receive diverse inputs and target multiple types of local cortical neurons, representing a critical circuit component. Yet, the precise contribution of SOM interneurons to cortical circuit function and behavioral performance remains unclear. Here we address this using cell-type specific imaging and perturbation during an auditory perceptual decision task. Two-photon calcium imaging reveals that SOM interneurons exhibit task enhanced responses and stimulus category selectivity. Simultaneous optogenetic inactivation and two-photon imaging show that SOM interneurons exert divergent effects of either sharpening the sensory tuning or scaling down the tuning peak on different proportions of auditory cortical neurons. At behavioral level, inactivation of SOM interneurons reveals a specific contribution to perceptual discriminability. Our data delineate the role of SOM interneurons in cortical processing and auditory perception, linking cell-type specific cortical circuit computations with perceptual functions.
Making memories last: The peripheral effect of direct current stimulation on strengthening memories
Authors: Luckey Alison M. , McLeod S. Lauren , Huang Yuefeng , Mohan Anusha , Vanneste Sven 
Published: July 2022

AbstractMost memories that are formed are forgotten, while others are retained longer and are subject to memory stabilization. We show that non-invasive transcutaneous electrical stimulation of the greater occipital nerve (NITESGON) using direct current during learning elicited a long-term memory effect. However, it did not trigger an immediate effect on learning. A neurobiological model of long-term memory proposes a mechanism by which memories that are initially unstable can be strengthened through subsequent novel experiences. In a series of studies, we demonstrate NITESGON’s capability to boost the retention of memories when applied shortly before, during or shortly after the time of learning by enhancing memory consolidation via activation and communication in and between the locus coeruleus pathway and hippocampus by modulating dopaminergic input. These findings may have a significant impact for neurocognitive disorders that inhibit memory consolidation such as Alzheimer’s disease.

Purpose
While there is increasing interest in implementing drug checking within overdose prevention, we must also consider how to scale-up these responses so that they have significant reach and impact for people navigating the unpredictable and increasingly complex drug supplies linked to overdose. The purpose of this paper is to present a distributed model of community drug checking that addresses multiple barriers to increasing the reach of drug checking as a response to the illicit drug overdose crisis.

Design/methodology/approach
A detailed description of the key components of a distributed model of community drug checking is provided. This includes an integrated software platform that links a multi-instrument, multi-site service design with online service options, a foundational database that provides storage and reporting functions and a community of practice to facilitate engagement and capacity building.

Findings
The distributed model diminishes the need for technicians at multiple sites while still providing point-of-care results with local harm reduction engagement and access to confirmatory testing online and in localized reporting. It also reduces the need for training in the technical components of drug checking (e.g. interpreting spectra) for harm reduction workers. Moreover, its real-time reporting capability keeps communities informed about the crisis. Sites are additionally supported by a community of practice.

Originality/value
This paper presents innovations in drug checking technologies and service design that attempt to overcome current financial and technical barriers towards scaling-up services to a more equitable and impactful level and effectively linking multiple urban and rural communities to report concentration levels for substances most linked to overdose.

What makes a product vintage? Investigating relationships between “consumer pastness,” scarcity and purchase intentions toward vintage products
Authors: Schibik Aaron , Strutton David , Thompson Kenneth Neil 
Published: July 2022

Purpose
This purpose of this study is to develop actionable marketing insights regarding why consumers might elect to purchase vintage products. A concept called consumer pastness is introduced, developed and defined to achieve this end. Consumer pastness demonstrably affected consumers’ perceptions of vintage products’ scarcity and consumers’ propensity to purchase vintage items. When applied inside marketing contexts, consumer pastness may also explain how and why consumers distinguish vintage products that are “of the past” from new and second-hand products. The data suggest that when consumers perceive products are characterized by higher consumer pastness the products will be perceived as scarcer, more desirable and more valuable than new or second-hand versions of the same item.

Design/methodology/approach
A scale was developed to capture three dimensions that comprise consumer pastness and then a pilot study and two experiments were conducted to test the research propositions.

Findings
Study propositions were confirmed. Consumers perceive vintage products as scarcer and more desirable than other types of products.

Originality/value
A novel and useful concept is introduced to the marketing literature inside this study. To the best of the authors’ knowledge, this study is the first to investigate and develop theoretical insights regarding how and why consumers perceive vintage products differently from new and second-hand products. The investigations reported below are also the first to develop practical insights regarding how management might respond to these insights about the role consumer pastness plays.

Authors: Aaltonen Kirsi , Turkulainen Virpi 
Published: July 2022

PurposeIn this study, we develop further understanding of how institutional change is created within a mature and local industry. In this pursuit, we examine how a collaborative large project governance model was institutionalized at an industrial sector-level through both industry-level activities and “institutional projects”.Design/methodology/approachThis study builds on the foundations of institutional fields and institutional change, suggesting that projects are not only shaped by their contexts but also produce institutional change themselves. We conducted extensive fieldwork on the institutionalization of a collaborative project governance model in Finland.FindingsThe findings illustrate how institutional change in governance of large and complex inter-organizational projects is created at the institutional field level. The institutionalized collaborative project governance model includes aspects of both relational and contractual governance. The change was facilitated by temporal links between the institutional projects as well as vertical links between the institutional projects and the field-level development programs.Originality/valueThis is one of the first studies to address how a collaborative large project governance model becomes the norm at the institutional field level beyond the boundaries of an individual project or organization.

Green in-store operations and sustainability performance: the moderating role of organization size
Authors: Qazi Sharfah Ahmad , Moazzam Muhammad , Ahmed Waqas , Raziq Muhammad Mustafa 
Published: July 2022

PurposeBusinesses are increasingly striving to become sustainable in terms of economic, environmental and social aspects. However, in the fresh food retail supply chains (SCs), achieving environmental objectives can be challenging because of the unique characteristics of products such as perishability, bulkiness, short product lifecycle and the requirement for cold chain infrastructure. The retail industry is the face of a SC. Therefore, its role in achieving sustainable objectives is pivotal. This study examines the effect of green in-store operations on sustainability performance indicators of fresh food retail and examines the moderating role of organization size in this context.Design/methodology/approachData are collected through surveys using self-administered questionnaires from 70 retail stores with 188 completed responses. Data are analyzed using structural equation modeling.FindingsResults show a positive relationship between green in-store operation with environmental social and economic performance. Furthermore, these relationships are moderated by the organization size such that the positive green in-store operation and performance relationships are stronger in the case of environmental and social performance only and for larger retail stores. No moderation is seen for economic performance.Originality/valueThe study broadens the understanding of green SC management’s effect on sustainability performance in the retail industry. It shows how the positive implications of a green SC are contingent on organization size and have prominence for environmental and social performance.
The social construction of executive pay: governance processes and institutional isomorphism
Authors: Perkins Stephen J. , Shortland Susan 
Published: July 2022

PurposeThe purpose of this paper is to explore the social construction of executive pay in the UK via an examination of narratives drawn from the social actors on the front-line of Key Management Personnel (KMP) pay determination.Design/methodology/approachThe authors' qualitative research draws upon in-depth interviews with non-executive directors (NEDs) serving on remuneration committees, institutional investors, and independent pay consultants.FindingsRegulation, market pricing and risk mitigation together with the social processes inherent within discharging corporate governance responsibilities create a status-quo-preserving isomorphic effect, restricting context-sensitive approaches to KMP pay determination.Practical implicationsThe paper informs action by company directors, investors and policy makers to address KMP pay controversies, building shared accountability amongst decision-makers focussed on more strategic context-aligned processes and outcomes.Originality/valueThe authors' analysis illustrates how institutional isomorphism can be applied to analyse social actors' interpretations within KMP pay decision-making. The authors show that normative, coercive and mimetic isomorphic forces must be applied in dynamic interaction to extend the explanatory power of institutional isomorphism through the creation of a “No-Come-In” effect in respect of contemporary KMP pay determination settings.

Published: July 2022

Abstract

The frequency, duration and magnitude of drought are projected to increase in the next few decades, with consequences for community composition and nutrient utilization of plants. Nutrient resorption, a process facilitating plant nutrient conservation, is a crucial driver for ecosystem nutrient cycling. It remains unknown how would extreme drought affect nutrient resorption of plant communities through changing community composition.

We examined the contributions of different processes (richness and identity effect of species losses and species gains, as well as the context dependent effect) related with community compositional changes to the alterations of community‐level nutrient resorption efficiency after 4‐year treatments of chronic drought (66% rainfall reduction from May to August) and intense drought (100% rainfall reduction in June and July) in a temperate steppe in Hulun Buir, Inner Mongolia, China.

Both chronic and intense drought significantly reduced nutrient resorption efficiency in most of the common species, but did not affect that at the community level. Drought‐induced losses of species made positive contribution to the community‐level nutrient resorption, as they generally had lower nutrient resorption efficiency. Such positive contribution balanced the negative effect of drought on the nutrient resorption of the common species.

Our results indicate that drought‐induced changes in community composition, especially those species being lost, were important in mediating the community‐level responses of nutrient resorption to extreme drought in grasslands.

Abstract

Riparian vegetation supports high biodiversity providing many services and is, therefore, an important landscape element. Riparian ecosystems are subject to numerous pressures leading to population decline and genetic erosion of riparian plants. This may have cascading effects at various ecosystem levels, including decreasing ecosystem services, so identifying the current status of genetic diversity of riparian tree species is vital to improve the effectiveness of restoration efforts.

We aimed to elicit expert views on the status and importance of genetic diversity of tree species, and conservation needs across European riparian ecosystems. Sharing of such information among researchers, managers and policymakers has the potential to enhance ecological restoration and management of riparian ecosystems.

We identified experts in riparian genetic resources conservation and management across Europe. These included stakeholders with different perspectives, ranging from researchers to practitioners. We designed a set of questionnaires where our identified experts were asked to answer questions related to the status and conservation of genetic diversity of riparian tree species in their respective countries. Specifically, we asked about societal awareness, legislative tools, good practices and conservation or restoration projects accounting for intraspecific genetic diversity and differentiation of tree species in riparian ecosystems. Questionnaire responses were analysed and discussed in light of the scientific literature to define needs and priorities related to the management and conservation of genetic diversity of riparian tree species.

The experts recognized that a combination of in situ and ex situ measures and/or integrative conservation of riparian ecosystems is the most appropriate option for conserving the genetic diversity of riparian tree species. Simultaneous application of conservation measures at the level of priority species, identified by experts, and protection of riparian areas are required.

Synthesis and applications. This study revealed the importance of recognizing the ecological processes that shape the genetic diversity of riparian tree species in hydrographic networks (dendritic spatial configuration, specific patterns of gene flow among riparian populations, fragmentation of river by dams) but also the need to overcome socio‐economic barriers, such as lack of policy priority, deficiency in funding and weak legislation framework.
