Stimulus-specific enhancement of responses in mouse primary visual cortex mediated by GABA release from VIP cells
Authors: Kaneko Megumi , Hoseini Mahmood S. , Waschek James A , Stryker Michael P. 
Published: June 2023

ABSTRACTWhen adult mice are repeatedly exposed to a particular visual stimulus for as little as one hour per day for several days while their visual cortex (V1) is in the high-gain state produced by locomotion, that specific stimulus elicits much stronger responses in V1 neurons for the following several weeks, even when measured in anesthetized animals. Such stimulus-specific enhancement (SSE) is not seen if locomotion is prevented. The effect of locomotion on cortical responses is mediated by vasoactive intestinal peptide (VIP) positive interneurons, which can release both the peptide and the inhibitory neurotransmitter GABA. Here we used genetic ablation to determine which of those molecules secreted by VIP-ergic neurons is responsible for SSE. SSE was not impaired by VIP deletion but was prevented by compromising release of GABA from VIP cells. This finding suggests that SSE may result from Hebbian mechanisms that remain present in adult V1.SIGNIFICANCEMany neurons package and release a peptide along with a conventional neurotransmitter. The conventional view is that such peptides exert late, slow effects on plasticity. We studied a form of cortical plasticity that depends on the activity of neurons that express both vasoactive intestinal peptide (VIP) and the inhibitory neurotransmitter GABA. GABA release accounted for their action on plasticity, with no effect of deleting the peptide on this phenomenon.

AbstractExploration-exploitation decision-making is a feature of daily life that is altered in a number of neuropsychiatric conditions. Humans display a range of exploration and exploitation behaviors, which can be affected by apathy and anxiety. It remains unknown how factors underlying decision-making generate the spectrum of observed exploration-exploitation behavior and how they relate to states of anxiety and apathy. Here, we report a latent structure underlying sequential exploration and exploitation decisions that explains variation in anxiety and apathy. 1001 participants in a gender-balanced sample completed a three-armed restless bandit task along with psychiatric symptom surveys. Using dimensionality reduction methods, we found that decision sequences reduced to a low-dimensional manifold. The axes of this manifold explained individual differences in thebalancebetween states of exploration and exploitation and thestabilityof those states, as determined by a statistical mechanics model of decision-making. Position along the balance axis was correlated with opposing symptoms of behavioral apathy and anxiety, while position along the stability axis correlated with the level of emotional apathy. This result resolves a paradox over how these symptoms can be correlated in samples but have opposite effects on behavior. Furthermore, this work provides a basis for using behavioral manifolds to reveal relationships between behavioral dynamics and affective states, with important implications for behavioral measurement approaches to neuropsychiatric conditions.

AbstractThe plasticity and growth of plant cell walls (CWs) remain poorly understood at the molecular level. In this work, we used atomic force microscopy (AFM) to observe elastic responses of the root transition zone of 4-day-oldArabidopsis thalianawild type andalmt1mutant seedlings grown under Fe or Al stresses. The elastic parameters were deduced from force-distance measurements by AFM using the trimechanic-3PCS framework. In all metal stresses tested, the presence of single metal species Fe2+or Al3+at 10 µM exerts no noticeable effect on the root growth compared with the control conditions. On the contrary, a mix of both the metal ions produced a strong root extension arrest concomitant with significant increase of CW stiffness. This was not found for thealmt1mutant which substantially abolishes the ability to exude malate. By raising the concentration of either Fe2+or Al3+to 20 µM, no root extension arrest was observed; nevertheless, a rise of root stiffness occurred. Our results indicate that the combination of Fe2+and Al3+with exuded malate is crucial for both CW stiffening and root extension arrest. However, stiffness increase induced by single Fe or Al metal is not sufficient for arresting root growth.Summary statementWe record the change in stiffness of the external primary cell wall of livingArabidopsis thalianaseedlings in presence of metallic stress using atomic force microscopy. Results reveals for the first time the uncoupling between mechanical response (CW stiffening) and root extension arrest.

Published: June 2023

SummaryIn early neurodevelopment, the central nervous system is established through the coordination of various neural organizers directing tissue patterning and cell differentiation. Better recapitulation of morphogen gradient production and signaling will be crucial for establishing improved developmental models of the brainin vitro. Here, we developed a method by assembling polydimethylsiloxane (PDMS) devices capable of generating a sustained chemical gradient to produce patterned brain organoids, which we termedMorphogen-gradientInducedBrainOrganoids (MIBOs). At 3.5 weeks, MIBOs replicated Dorsal-Ventral patterning observed in the Ganglionic Eminence (GE). Analysis of matured MIBOs through single-cell RNA sequencing revealed distinct Dorsal GE derived CALB2+ interneurons (INs), Medium Spiny Neurons (MSNs), and MGE derived cell types. Finally, we demonstrate long term culturing capabilities with MIBOs maintaining stable neural activity in cultures grown up to 5.5 months. MIBOs demonstrate a versatile approach for generating spatially patterned brain organoids for embryonic development and disease modeling.MotivationThe use of small molecules for the guided differentiation of brain organoids has proven to be a useful tool for modeling various aspects of early neurodevelopment. Still, the embryonic brain is patterned through a combination of morphogen gradients stemming from organizer regions. To address this inconsistency, we designed a device capable of mimicking neural organizers by maintaining a steady morphogen gradient. We used this device to expose forebrain organoids to multiple gradient conditions and cataloged the diversity of cell types produced.
Whether corporate social responsibility is used to suppress earnings management practices and could corporate governance mechanisms prevent them? An empirical study
Authors: Dissanayake Sulochana , Ajward Roshan , Dissanayake Dilini 
Published: June 2023

PurposeThis study examines whether managers adopt corporate social responsibility (CSR) disclosures to suppress earnings management practices and whether corporate governance mechanisms could limit such practices.Design/methodology/approachA quantitative approach was followed, in which secondary data from listed firms from 2014 to 2019 were gathered. Descriptive statistics and inferential techniques were performed, which included correlation, ordered logistic regression and 2SLS panel regression analyses.FindingsThe findings indicate that firms use CSR disclosure to conceal managers' opportunistic behaviour via earnings management as an entrenchment strategy and that corporate governance mechanisms could significantly constrain such behaviour.Research limitations/implicationsThis study goes beyond the conventional agency theory by incorporating additional theoretical perspectives from stakeholder and legitimacy theories, resulting in a multi-theoretical perspective in conceptualizing the study.Practical implicationsThe findings are expected to have significant policy implications, especially in limiting the opportunistic use of CSR disclosures and reducing earnings management practices to safeguard stakeholders' interests and ensure the sustainability of business entities.Originality/valueThe levels of CSR and board governance practices are captured using comprehensive indices. Moreover, earnings management was operationalized using both accrual-based and real earnings management proxies. Furthermore, while addressing an empirical dearth noted, the findings provide significant policy implications for limiting managers' opportunistic and unethical use of CSR disclosures with corporate governance mechanisms.
Magneto-bioconvection flow in a porous annulus between circular cylinders containing oxytactic microorganisms and NEPCM
Authors: Alsedais Noura , Al-Hanaya Amal , Aly Abdelraheem M. 
Published: June 2023

Purpose
This paper aims to investigate magnetic impacts on bioconvection flow within a porous annulus between an outer cylinder and five inner cylinders. The annulus is filled by oxytactic microorganisms and nano-encapsulated phase change materials.

Design/methodology/approach
The modified ISPH method based on the time-fractional derivative is applied to solve the regulating equations in Lagrangian dimensionless forms. The pertinent factors are bioconvection Rayleigh number Rab (1–100), circular cylinder’s radius Rc (0.1–0.3), fractional time derivative α (0.95–1), Darcy parameter Da (10−5–10−2), nanoparticle parameter ϕ (0–0.1), Hartmann number Ha (0–50), Lewis number Le (1–20), Peclet number Pe (0.1–0.75), s (0.1–0.9), number of cylinders NCylinders (1–4), Rayleigh number Ra (103–106) and fusion temperature θf (0.005–0.9).

Findings
The simulations revealed that there is a strong enhancement in the velocity field according to an increase in Rab. The intensity and location of the phase zone change in response to changes in θf. The time-fractional derivative a acting on a nanofluid velocity and flow characteristics in an annulus. The number of embedded cylinders NCylinders is playing a significant role in the cooling processes and as NCylinders increases from 1 to 4, the velocity field’s maximum reduces by almost 33.3%.

Originality/value
The novelty of this study is examining the impacts of the magnetic field and the presence of several numbers of embedded cylinders on bioconvection flow within a porous annulus between an outer cylinder and five inner cylinders.
Vulnerable customers' perception of corporate social responsibility in the banking sector in a post-crisis context
Authors: Monferrer Tirado Diego , Vidal-Meliá Lidia , Cardiff John , Quille Keith 
Published: June 2023

PurposeThis research aims to determine to what extent corporate social responsibility (CSR) actions developed by bank entities in Spain improve the vulnerable customers' emotions and quality perception of the banking service. Consequently, this increases the quality of their relationship regarding satisfaction, trust and engagement.Design/methodology/approachData from 734 vulnerable banking customers were analyzed through structural equations modeling (EQS 6.2) to test the relationships of the proposed variables.FindingsVulnerable customers' emotional disposition exerts a strong influence on their perceived service quality. The antecedent effect is concentrated primarily on the CSR towards the client, with a residual secondary weight on the CSR towards society. These positive service emotions are determinants of the outcome quality perceived by vulnerable customers, directly in terms of higher satisfaction and trust and indirectly through engagement.Practical implicationsThis research contributes to understanding how financial service providers should adapt to the specific characteristics and needs of vulnerable clients by adopting a strategy of approach, personalization and humanization of the service that seems to move away from the actions implemented by the banking industry in recent years.Originality/valueThis study has adopted a theoretical and empirical perspective on the impact of CSR on service emotions and outcome quality of vulnerable banking customers. Moreover, banks can adopt a dual conception of CSR: a macro and external scope toward society and a micro and internal scope toward customers.
Seize the favorable impression: how hosts should manage positive online reviews
Authors: Wang Bo , Jia Ting 
Published: June 2023

Purpose
Positive reviews can enrich the favorable impression of peer-to-peer accommodation products, and seizing this impression is vital for hosts. This study aims to focus on hosts’ response strategies to positive reviews and their effects.

Design/methodology/approach
This study categorizes hosts’ response strategies to positive reviews into cordial and tailoring responses. This study empirically analyzes the influence of these response strategies on subsequent review volumes using 1,283 valid listings and zero-inflation negative binomial regression models.

Findings
While hosts use cordial responses more, tailoring responses are more likely to drive subsequent reviews. In addition, when the host chooses entirely shared accommodation or sets a high price, the facilitating effect of the two response strategies on subsequent reviews weakens.

Research limitations/implications
This study enriches the knowledge system on managerial responses by proposing two specific response strategies to positive reviews that can be adopted by peer-to-peer accommodation hosts and by finding the promoting impact of these strategies on subsequent review volumes.

Practical implications
This study recommends that peer-to-peer accommodation hosts adopt cordial and tailoring responses to encourage subsequent consumer reviewing behavior.

Originality/value
As an early attempt to explore hosts’ responses to positive reviews and their impacts on subsequent review volumes, this study provides valuable insights into further research on positive review response strategies in the digital space.
The bright and dark sides of ESG during the COVID-19 pandemic: evidence from China hospitality industry
Authors: Lin Yongjia , Lu Zhenye , Fan Di , Zheng Zhen 
Published: June 2023

Purpose
This study aims to investigate the bright and dark sides of environmental, social and governance (ESG) during the COVID-19 pandemic, including both the outbreak and recovery periods, for the Chinese hospitality industry.

Design/methodology/approach
Using panel data of 564 firm-quarter observations from 2018 to 2020, the authors adopt fixed-effects regression estimation with standard errors clustered at the firm level. To address potential endogeneity concerns, the authors also use the two-stage least squares estimator with instrumental variables.

Findings
The results suggest that ESG plays different roles in market- and accounting-based performance during the COVID-19 outbreak and recovery periods. Specifically, ESG practices show a bright side as a reputation builder to mitigate the negative pandemic impact on market-based performance, whereas the dark side of ESG practices consumes firm resources to aggravate the negative pandemic impact on accounting-based performance during the coronavirus outbreak. These results also suggest hospitality companies benefit bountifully from ESG practices during the COVID-19 recovery.

Practical implications
ESG plays a vital role for hospitality firms by providing insurance-like protection during and after the COVID-19 outbreak. Additionally, hospitality firms should evaluate their capability to adapt resource-consuming ESG practices.

Originality/value
Existing hospitality COVID-19 studies have investigated the effect of ESG on firm performance within a short period with mixed results. This study extends the literature by showing the different effects of ESG practices on market- and accounting-based performance during the COVID-19 outbreak and recovery periods.
Deciphering factors that make a narcissistically loved salon brand
Authors: Sarkar Abhigyan , Gahlot Sarkar Juhi , Jain Kokil , Sharma Isha 
Published: June 2023

PurposeThis research is conducted in the context of beauty salons in India, to investigate how enhanced perceived acceptance in interpersonal relationships through consuming beauty salon services can generate narcissistic brand love among consumers via the mediation of brand happiness. It also investigates the moderating impact of consumer's anxious interpersonal attachment style and cynicism on the relationship between perceived salon brand-interpersonal acceptance goal congruence and salon brand happiness.Design/methodology/approachTo test the hypothesized relationships, a survey was conducted among 225 regular consumers of beauty salon brands. The data were analyzed using Hayes' (2017) process macro in SPSS.FindingsThe results suggest that perceived goal congruence between beauty salon brand-interpersonal acceptance positively influences brand happiness, which in turn predicts consumer's narcissistic brand love. Consumer's anxious interpersonal attachment style positively moderates the effect of brand-interpersonal acceptance goal congruence on brand happiness, while cynicism negatively moderates the path.Originality/valueValue of the study lies in extending interpersonal acceptance and rejection (IPAR) theory to the domain of consumer–salon brand relationship, to posit that if salon brands satisfy consumers' interpersonal acceptance goals, there is a potential for such happy consumers to love the salon brand, albeit narcissistically.
Prison to desistance: (re)integration and aftercare for those released from prison
Authors: Youssef Carollyne 
Published: June 2023

Purpose
Most prisoners are eventually returned to their communities, making their transition into the community and aftercare a fundamental aspect of successful re-entry. This paper aims to explore the stages of someone’s reintegration from pre-release, through to reintegration and desistance and consider the factors relevant to the re-entry process for those who have offended and how to enhance this process. The aim of this paper was twofold; first to highlight the various factors and issues involved in the re-entry and reintegration process, particularly for those who are released after imprisonment and, second, to consider the significance of aftercare services in facilitating this process.

Design/methodology/approach
This paper opted for a brief review of the literature regarding incarceration and reintegration and some of the gaps in the literature. This paper will commence with a discussion of the effects of imprisonment on those who are incarcerated, then a consideration of the re-entry process, followed by a discussion of the reintegration process and desistance. Following will be reflections regarding the implications for practice. A case study is used to illustrate these points.

Findings
The current paper proposes a framework by which organisations and service providers working with those who are released from prison can use or incorporate into their practice to enhance aftercare support. The case study is used as an example to further illustrate this.

Practical implications
Implications for practice are also considered as well as recommendations to aid the re-entry and aftercare process. Suggestions are also offered to those agencies that are responsible for the provision of aftercare services for those released from prison.

Originality/value
This paper offers some considerations regarding the importance of the preparing and planning for release with a specific focus on aftercare services and their role in the re-entry and reintegration process.
The effective measurement of shared leadership: a multi-scale comparison
Authors: Spedding Jason , Brough Paula , Hawkes Amy Jane , Chan Xi Wen 
Published: June 2023

PurposeDue to the proliferation of measures (and conceptualisations) employed to assess shared leadership behaviours, it is unclear to researchers and practitioners which specific team behaviours should be encouraged and which measures should be included in research to enhance team effectiveness outcomes. To address this issue, this research tests 11 shared leadership scales to identify which measures and behaviours exhibit the strongest relationship with team effectiveness.Design/methodology/approachThis research utilises survey methods (n = 328) to test the measurement of shared leadership using 11 previously validated scales. This novel approach uses structural equation modelling techniques (SEM) to compare and contrast multiple measures targeting a single underlying construct.FindingsAcross the 11 measures tested (drawn from three theoretical perspectives), no single scale demonstrated a superior ability to assess shared leadership (based on model-fit and effect size exhibited). Nevertheless, the results indicated that measures assessing shared transformational leadership were most highly related to team effectiveness; whilst the shared leadership density measure (using social network techniques) exhibited the weakest relationship.Research limitations/implicationsLimitations of this research include the use of a student sample (although participants were screened based on their current employment in a team environment), and the individual assessment of shared leadership rather than team assessment. These findings indicate that shared transformational leadership behaviours are highly related to perceptions of team effectiveness. It is recommended future research define and delineate between constructs of interest, including general forms shared leadership (i.e. shared leadership broadly defined) and more specific forms of shared leadership (e.g. shared transformational leadership [narrowly defined]).Practical implicationsIt is recommended that interventions and/or training designed to enhance team shared leadership outcomes should specifically target shared transformational leadership behaviours; especially when aiming to increase beneficial team outcomes such as effectiveness or potency.Originality/valueThis research is novel in both advancing our understanding of the shared leadership behaviours needed to enhance team effectiveness; and in methodological approaches comparing and contrasting multiple measures of a single latent construct.
