Enhancing brand experience in the online social media network context: a contingency perspective
Authors: Marmat Geeta 
Published: August 2021

PurposeMarketing and branding literature has provided important insights into the context, environment and individual factors that shape customer brand experience. However, a holistic view on context and environmental influence on enhancing brand experience, specifically in the online social media network context, has not been considered. In addition, main focus of the previous research is on antecedent and consequence of brand experience rather strategy for enhancing brand experience. This paper aims to propose a contingency model for enhancing brand experience to provide a more holistic framework in the uncertain and complex nature of online social media network.Design/methodology/approachThe proposed framework is based on previous literature that is identified and integrated to propose effectiveness of the contingent determinants on brand experience in different interactional circumstances.FindingsThe proposed framework implies that brand characteristics and interactive complexities of online social media networks cause contingency to the marketers or brands’ strategic attempt in delivering superior brand experience in online social media network context. These forces are as follows: online social media network characteristic (interactivity); brands’ co-creation characteristics (consumers’ and stakeholders’ participation); brand’s technical and operational competency (brands’ knowledge, ease of interactive platform); internal human resource characteristics (employees’ behaviour, brands culture, brands reputation); and customer interactive characteristics (customer demographic characteristics, customer motivation, customer attitude). These identified forces can be optimized to formulate strategies in the interactive medium for enhancing brand experience.Research limitations/implicationsThis paper proposes a contingency model as well as research propositions that need to be validated and confirmed empirically. While narrowing down the current identified gap in brand experience literature by proposing a novel perspective to the concept, this research broadens and deepens understanding of the concept of brand experiences, how it is linked to the context and contextual factors. This contingency framework elucidates the resources that marketers, practitioners can use to enhance, limit or maintain all the dimensions within brand experience.Originality/valueA holistic view on context and environmental influence on enhancing brand experience, specifically in the online social media network context, has not been considered so far. Although literature demonstrates the positive outcome of brand experience, little attention has been paid to enhancing customer brand experience, specifically in the context of online social media networks with various complex forces acting and influencing the way customers experience a brand.
Animosity leads to boycott and subsequent reluctance to buy: evidence from Sino Indian disputes
Authors: Verma Pranay 
Published: August 2021

Purpose
The purpose of this paper is to investigate if animosity outbreaks against China result in a consumer’s reluctance to buy Chinese goods. It further studies the relationship of consumer animosity upon boycott and reluctance to buy (RTB).

Design/methodology/approach
A descriptive research design was applied by using the self-administered survey method for collecting data from 473 participants, mostly working graduates from the metropolitan city of Delhi in India. Thereafter, the measurement model was checked by confirming the reliability and validity of the constructs followed by checking for the strength and direction of the proposed hypothesis of the structural model (using SPSS 23 and AMOS 20) and to validate the proposed model developed based on the regret theory.

Findings
All the three types of animosity tend to negatively influence the buying behavior. When markets mature, consumers become concerned about their country’s civil status and boycott goods from hostile countries or places. Through this research, it is possible to find consequences of animosity on Chinese goods consumption, which is RTB. Boycott mediates the animosity relationship with RTB. The regret theory implies that individuals hold self-blame for taking an alternative decision. Domestic market players like local retailers, merchandisers, importers avoiding importing products originating from offending countries would be the managerial implications.

Originality/value
Consumer boycott is not unheard of in a Sino Indian context, but it lacks empirical research. This paper addresses perceived hostilities between two emerging super powers by applying the regret theory.
The Impact of Choosing Wisely Interventions on Low‐Value Medical Services: A Systematic Review
Authors: CLIFF BETSY Q. , AVANCEÑA ANTON L.V. , HIRTH RICHARD A. , LEE SHOOU‐YIH DANIEL 
Published: August 2021

Policy Points
Dissemination of Choosing Wisely guidelines alone is unlikely to reduce the use of low‐value health services.
Interventions by health systems to implement Choosing Wisely guidelines can reduce the use of low‐value services.
Multicomponent interventions targeting clinicians are currently the most effective types of interventions.
ContextChoosing Wisely aims to reduce the use of unnecessary, low‐value medical services through development of recommendations related to service utilization. Despite the creation and dissemination of these recommendations, evidence shows low‐value services are still prevalent. This paper synthesizes literature on interventions designed to reduce medical care identified as low value by Choosing Wisely and evaluates which intervention characteristics are most effective.MethodsWe searched peer‐reviewed and gray literature from the inception of Choosing Wisely in 2012 through June 2019 to identify interventions in the United States motivated by or using Choosing Wisely recommendations. We also included studies measuring the impact of Choosing Wisely on its own, without interventions. We developed a coding guide and established coding agreement. We coded all included articles for types of services targeted, components of each intervention, results of the intervention, study type, and, where applicable, study quality. We measured the success rate of interventions, using chi‐squared tests or Wald tests to compare across interventions.FindingsWe reviewed 131 articles. Eighty‐eight percent of interventions focused on clinicians only; 48% included multiple components. Compared with dissemination of Choosing Wisely recommendations only, active interventions were more likely to generate intended results (65% vs 13%, p < 0.001) and, among those, interventions with multiple components were more successful than those with one component (77% vs 47%, p = 0.002). The type of services targeted did not matter for success. Clinician‐based interventions were more effective than consumer‐based, though there is a dearth of studies on consumer‐based interventions. Only 17% of studies included a control arm.ConclusionsInterventions built on the Choosing Wisely recommendations can be effective at changing practice patterns to reduce the use of low‐value care. Interventions are more effective when targeting clinicians and using more than one component. There is a need for high‐quality studies that include active controls.
Kitchen Window Feminism: Sarah Macnaughtan, Wartime Care and the Authority of Experience in the South African and First World Wars
Authors: Soja Taylor 
Published: August 2021

ABSTRACTSarah Macnaughtan, a wealthy novelist, used volunteer care work to claim the legitimacy of her wartime experience in the South African and First World Wars and to assert women's rights in the early twentieth‐century British empire. Macnaughtan framed her caregiving experiences in both inherently domestic terms – ‘from a kitchen window’ – and as a justification for women's suffrage and participation in public life. Her example loosens a persistent binary between trained nurses and untrained wartime volunteers and highlights the importance of precedents set in the British empire to the feminist politics and caring practices of the First World War.
The Joint Influence of Information Push and Value Relevance on Investor Judgments and Market Efficiency

Published: August 2021

ABSTRACTWe use experimental markets to examine how pushing investment information and the value relevance of that information interact to influence investors’ value estimate accuracy and market price efficiency. Developments in technology allow information to be pushed to investors anytime and anywhere. However, in addition to value‐relevant information, pushed information often includes information that is irrelevant for assessing firm value. Drawing on psychology theory, we find that pushing information has divergent effects depending on the value relevance of the information. Pushing only value‐relevant information increases investors’ processing of the information and leads to more accurate value estimates and market prices than when not pushed. In contrast, pushing a mix of value‐relevant and value‐irrelevant information reduces investors’ processing of value‐relevant information, leading to less accurate value estimates and market prices due to poorer acquisition and integration of information than when not pushed or when only value‐relevant information is pushed. Collectively, our results reveal a dark side to push technologies, particularly with the growing presence of value‐irrelevant information.
Social media, socialization, and pursuing legitimation of police violence*
Authors: Cheng Tony 
Published: August 2021

AbstractEvery day, police departments across America are executing stops, summonses, arrests, and increasingly, tweeting. Although scholarship has focused on how social media democratizes news production and information sharing for activist movements, it has yet to explore how police leverage these attributes to advance institutional interests. I argue that, beyond digital surveillance or community engagement, social media provides police with the technological capacity to pursue both daily socialization of online audiences to their worldview and legitimation in the aftermath of contested police violence. I provide evidence by adopting a qualitative approach to “big data” sources analyzing 1) all 3,167 tweets posted by the New York Police Department in 2018; 2) the 778 Twitter replies to their most contested fatal shooting that year; and 3) a sample of 139 news articles covering this shooting over a year afterward. As public scrutiny toward police intensifies, social media represents an independent channel for police to publicize information unfiltered by traditional mass media. These findings have implications for police accountability and the episodes of police violence that do—and do not—elevate into national controversies.
Life lessons: Examining sources of racial and ethnic disparity in federal life without parole sentences*
Authors: Johnson Brian D. , Spohn Cassia , Kimchi Anat 
Published: August 2021

AbstractAlongside capital punishment, sentences to life without the possibility of parole are one of the most distinctive aspects of the American system of criminal punishment. Unlike the death penalty, though, almost no empirical work has examined the decision to impose life imprisonment. The current study analyzes several years of recent federal sentencing data (FY2010–FY2017) to investigate underlying sources of racial disparity in life without parole sentences. The analysis reveals disparities in who receives life imprisonment, but it finds these differences are attributable mostly to indirect mechanisms built into the federal sentencing system, such as the mode of conviction, mandatory minimums, and guidelines departures. Both Black and Hispanic offenders are more likely to be eligible for life sentences under the federal guidelines, but conditional on being eligible, they are not more likely to receive life sentences. Findings are discussed in relation to ongoing debates over racial inequality and the growing role that life imprisonment plays in American exceptionalism in punishment.

Published: August 2021

SummaryIn order to keep pace with the evolution of the objectives and means of the EU's Common Agricultural Policy, evaluation tools also need to adapt. A set of tools that have proved highly effective in other policy fields is economic experiments. These allow the testing of a new policy before its implementation, provide evidence of its specific effects, and identify behavioural dimensions that can influence policy outcomes. We argue that agricultural policy should be subject to economic experiments, providing examples to illustrate how they can inform CAP design. We identify the additional efforts needed to establish further proof‐of‐concept, by running more – and more robust – experiments related to the CAP. This can happen only by integrating experimental evaluation results within the policy cycle and addressing ethical and practical challenges seriously. To do so, researchers would benefit from a concerted European effort to promote the methodology across the EU; organise the replication in time and across Europe of experiments relevant for the CAP; and build a multi‐national panel of farmers willing to participate in experiments. Steps are being taken in this direction by the Research Network of Economics Experiments for CAP evaluation (REECAP).

Published: August 2021

AbstractBackgroundOncology patients carry a substantial risk of developing pleural empyema. Here, we report the preliminary results of our early video‐assisted thoracoscopic surgery (VATS) lavage strategy in cases of empyema occurring in patients undergoing (radio‐) chemotherapy.MethodsThis was a retrospective case–control study comparing early VATS lavage (test group, current therapy since January 2018, n = 46) versus VATS pleurectomy (historical control; before January 2018, n = 46).ResultsFive patients in the control group and one in the test group developed recurrence of empyema within 30 days. Complications were more severe and more frequently observed in the historical control group than in the test group (30/46 vs. 12/46 CI: 5%–95%, p = < 0.05). Early VATS lavage saved operating time, allowed a shorter ICU stay (2.6 days CI: 5%–95% vs. 5.1 days CI: 5%–95%, p = ns) and an earlier hospital discharge (6.1 days CI: 5%–95% vs. 13.5 days CI: 5%–95%, p < 0.05). Moreover, radio and/or chemotherapy could be reinitiated earlier (15 ± 20.5 days CI: 5%–95% vs. 40 ± 12 days CI: 5%–95%, p < 0.05).ConclusionsIn this retrospective cohort study, early VATS lavage was found to have a beneficial effect especially on hospital stay and enabling an earlier restart of radio‐ and/or chemotherapy.
Do xerophytic and mesophytic perennial grasses differ in soil resource capture and allocation? A field 15N experiment
Authors: Reyes Maria Fernanda , Aguiar Martín R. 
Published: August 2021

AbstractIn rangelands, pattern and processes below‐ground are important for a complete understanding of their ecology. Recent studies in grass‐dominated communities in Europe, North America and South America indicate that root systems of several species may overlap their root systems. This may indicate that, in these communities, resource acquisition and allocation strategies could play a relevant role in community assemblage. Resources absorption and allocation may be related to ecological strategies relevant in an arid steppe. Here, we explore if coexisting xerophytic and mesophytic perennial grasses differ in resource absorption and allocation to below‐ and above‐ground portions. We conducted a field labelling experiment to trace 15N (nitrogen) to compare acquisition and relative below‐ and above‐ground nitrogen allocation among four perennial grass species. We worked with two mesophytic (fast‐growing) and two xerophytic (slow‐growing) species. Our hypothesis was that mesophytic species will allocate greater proportions of N and produce a higher amount of biomass than xerophytic species. The four species showed similar 15N concentration, which changed over time in roots, while it remained constant in leaves. On average, all species presented 0.9% 15N atom excess in roots and 1.1% in green leaves. Mesophytic species showed higher reproductive over total tiller ratio than xerophytic species. Bromus pictus reached 60% while Poa ligularis only 20%. In xerophytic species (Pappostipa speciosa and Pappostipa humilis), this ratio was close to 0%. Despite their differences in growth rates, these mesophytic and xerophytic grass species do not differ in the estimated nitrogen acquisition. Nevertheless, there are ecological trade‐offs between allocating resources to above‐ground leaf biomass and reproductive tillers which could be related to species organisation in the community.

SummaryHigh‐flow nasal oxygen used before and during apnoea prolongs time to desaturation at induction of anaesthesia. It is unclear how much oxygenation before apnoea prolongs this time. We randomly allocated 84 participants to 3 minutes of pre‐oxygenation by one of three methods: 15 l.min‐1 by facemask; 50 l.min‐1 by high‐flow nasal cannulae only; or 50 l.min‐1 by high‐flow nasal cannulae plus 15 l.min‐1 by mouthpiece. We then anaesthetised and intubated the trachea of 79 participants and waited for oxygen saturation to fall to 92%. Median (IQR [range]) times to desaturate to 92% after pre‐oxygenation with facemask oxygen, high‐flow nasal oxygen only and high‐flow nasal oxygen with mouthpiece, were: 309 (208‐417 [107‐544]) s; 344 (250‐393 [194‐585]) s; and 386 (328‐498 [182‐852]) s, respectively, p = 0.014. Time to desaturation after facemask pre‐oxygenation was shorter than after combined nasal and mouthpiece pre‐oxygenation, p = 0.006. We could not statistically distinguish high‐flow nasal oxygen without mouthpiece from the other two groups for this outcome. Median (IQR [range]) arterial oxygen partial pressure after 3 minutes of pre‐oxygenation by facemask, nasal cannulae and nasal cannulae plus mouthpiece, was: 49 (36‐61 [24‐66]) kPa; 57 (48‐62 [30‐69]) kPa; and 61 (55‐64 [36‐72]) kPa, respectively, p = 0.003. Oxygen partial pressure after 3 minutes of pre‐oxygenation with nasal and mouthpiece combination was greater than after facemask pre‐oxygenation, p = 0.002, and after high‐flow nasal oxygen alone, p = 0.016. We did not reject the null hypothesis for the pairwise comparison of facemask pre‐oxygenation and high‐flow nasal pre‐oxygenation, p = 0.14.
What lessons can surgeons learn from sport? The reflections of a retired athlete
Authors: Tapper Richard 
Published: August 2021

AbstractSurgery often looks to other domains of high performance such as the airline industry for ideas on how to improve surgical performance however little is written about what surgeons might learn from high performance sport. In this paper I offer some observations and ideas from my experience as an Olympic swimmer which I feel may be applicable to surgery and some thoughts on how these concepts might be introduced.

Published: August 2021

AbstractAimWe aimed at identifying potential roles of vesicular monoamine transporter 2, also known as Solute Carrier protein 18 A2 (SLC18A2) (hereafter, Vmat2), in brain monoamine regulation, their turnover, behaviour and brain development using a novel zebrafish model.MethodsA zebrafish strain lacking functional Vmat2 was generated with the CRISPR/Cas9 system. Larval behaviour and heart rate were monitored. Monoamines and their metabolites were analysed with high‐pressure liquid chromatography. Amine synthesising and degrading enzymes, and genes essential for brain development, were analysed with quantitative PCR, in situ hybridisation and immunocytochemistry.ResultsThe 5‐bp deletion in exon 3 caused an early frameshift and was lethal within 2 weeks post‐fertilisation. Homozygous mutants (hereafter, mutants) displayed normal low locomotor activity during night‐time but aberrant response to illumination changes. In mutants dopamine, noradrenaline, 5‐hydroxytryptamine and histamine levels were reduced, whereas levels of dopamine and 5‐hydroxytryptamine metabolites were increased, implying elevated monoamine turnover. Consistently, there were fewer histamine, 5‐hydroxytryptamine and dopamine immunoreactive cells. Cellular dopamine immunostaining, in wild‐type larvae more prominent in tyrosine hydroxylase 1 (Th1)‐expressing than in Th2‐expressing neurons, was absent in mutants. Despite reduced dopamine levels, mutants presented upregulated dopamine‐synthesising enzymes. Further, in mutants the number of histidine decarboxylase‐expressing neurons was increased, notch1a and pax2a were downregulated in brain proliferative zones.ConclusionLack of Vmat2 increases monoamine turnover and upregulates genes encoding amine‐synthesising enzymes, including histidine decarboxylase. Notch1a and pax2a, genes implicated in stem cell development, are downregulated in mutants. The zebrafish vmat2 mutant strain may be a useful model to study how monoamine transport affects brain development and function, and for use in drug screening.
Utility of progesterone receptor‐ires‐Cre to generate conditional knockout mice for uterine study

Published: August 2021

AbstractIn mice, the conditional knockout strategy using the Cre‐loxP system is useful for various types of research. The Cre mouse line with progesterone receptor promoter (PgrCre) has been widely used to produce specific uterine gene‐deficient mice, but in the Cre line, endogenous Pgr gene is replaced by Cre recombinase gene, which makes the breeding of homozygous mice (PgrCre/Cre) difficult because they are infertile. Yang et al. (2013, https://10.1016/j.cell.2013.04.017) reported the generation of another PgriresCre mouse line that still has endogenous Pgr gene, and they inserted Cre recombinase downstream of the Pgr gene via an internal ribosome entry site (IRES). It is possible that this new PgriresCre line would be useful for uterine research as the mice can be bred as homozygotes (PgriresCre/iresCre). Herein, we confirmed the PgriresCre mice effectively directed recombination in the female reproductive tract and was capable of genetic alteration in the endometrium that enables the studies of its uterine function. Our findings demonstrate that the new PgriresCre mouse line is also useful for the generation of uterine‐specific knockout mice. The findings using PgriresCre mouse will contribute to the understanding of reproductive systems and diseases in humans and domestic animals.
