Dynamic pricing of perishable food as a sustainable business model
Authors: Scholz Michael , Kulko Roman-David 
Published: September 2021

PurposeThe purpose of this paper is to (1) investigate the effect of freshness on consumers' willingness to pay, (2) derive static and dynamic pricing strategies and (3) compare the effect of these pricing strategies on a retailer's revenue and food waste. This investigation helps to reveal the potentials of dynamic pricing strategies for building more sustainable business models.Design/methodology/approachThe authors conduct an online experiment to measure consumers' willingness to pay for fresh and three-days’ old strawberries. The impact of freshness on willingness to pay is analysed using univariate tests and regression analysis. Pricing strategies are compared using a Monte Carlo simulation.FindingsThe results of this study show that freshness largely determines consumers' willingness to pay and price sensitivity. This renders dynamic pricing a promising strategy from an economic point of view. The results of the simulation study show that food waste can be reduced by up to 53.6% with a dynamic pricing instead of a static pricing strategy in the case that there are as many consumers as strawberry packages in the inventory. Revenue can be increased by up to 10% compared to a static pricing strategy based on fresh strawberries.Practical implicationsThis study suggests that food retailers can improve their revenue when switching from static to dynamic pricing. Furthermore, in most cases, food retailers can reduce food waste with a dynamic instead of a static-pricing strategy, which might help to improve their image through a more sustainable business model and attract additional consumers.Originality/valueThis study is the first to analyse the possibility of using food freshness to design a dynamic pricing strategy and to analyse the impact of such a pricing strategy on both, a retailer's revenue and a retailer's food waste.
Financial analysts' reaction to voluntary integrated reporting: cross-sectional variation in institutional enforcement contexts
Authors: Rossignoli Francesca , Stacchezzini Riccardo , Lai Alessandro 
Published: September 2021

PurposeEuropean countries are likely to increasingly adopt integrated reporting (IR) voluntarily, after the 2014/95/EU Directive is revised and other initiatives are implemented. Therefore, the present study provides insights on the relevance of IR in voluntary contexts by exploring analysts' reactions to the release of integrated reports in diverse institutional settings.Design/methodology/approachDrawing on voluntary disclosure theory, a quantitative empirical research method is used to explore the moderating role of country-level institutional characteristics on the associations between voluntary IR release and analyst forecast accuracy and dispersion.FindingsIR informativeness is not uniform in the voluntary context and institutional settings play a moderating role. IR release is associated with increased consensus among analyst forecasts. However, in countries with weak institutional enforcement, a reverse association is detected, indicating that analysts rely largely on IR where the institutional setting strongly protects investors. Although a strong institutional setting boosts the IR release usefulness in terms of accuracy, it creates noise in analyst consensus.Research limitations/implicationsAcademics can appreciate the usefulness of voluntary IR across the institutional enforcement contexts.Practical implicationsManagers can use these findings to understand opportunities offered by IR voluntary release. The study recommends that policymakers, standard setters and regulators strengthen the institutional enforcement of sustainability disclosure.Originality/valueThis study is a unique contribution to recent calls for research on the effects of nonfinancial disclosure regulation and on IR “impacts”. It shows on the international scale that IR usefulness for analysts is moderated by institutional patterns, not country-level institutional characteristics.

Published: September 2021

PurposeThe purpose of this research was to develop a conceptualization and measure of workplace coachability.Design/methodology/approachUsing four independent samples of employed adults, we developed a short and long version of the Coachability Scale. We followed standard scale development practices, presenting evidence of the scales’ factor structure, reliability and validity.FindingsWith the first two samples, we derived an initial three-dimensional version of the Coachability Scale and provided evidence of convergent validity. With Samples 3 and 4, we expanded the scale with additional dimensions related to coaching feedback processes and accumulated additional evidence of the scale's validity, and provided evidence of convergence between the two versions of the Coachability Scale.Research limitations/implicationsWe encourage continued research on the Coachability Scale, as well as research on coachability in formal coaching relationships and with more diverse populations and cultures. It is also important to examine how coachability relates to specific coachee behaviors and outcomes. Although common method bias may be a limitation, we used temporally separated measurements to minimize method bias in Sample 4.Practical implicationsKnowledge about coachability can inform coaching practice decisions and help tailor the coaching engagement to better fit the coachee's needs.Social implicationsMeasuring how individuals respond to coaching and coaching relationships has important implications for managerial behavior and the quality of work life.Originality/valueThis is one of the first studies to develop valid scales for assessing workplace coachability.

AbstractBdallophytum oxylepis is a rare and endemic species belonging to the Cytinaceae family, a root holoparasitic plant in which most resources are allocated to attracting pollinators. This species is gynomonoecious with intraindividual variation in flower size and sex. Moreover, the flowers exhibit sapromyophilous traits, as do other species of Bdallophytum. Firstly, this study aimed to determine whether all floral morphs can form seeds and be pollen donors (in the case of bisexual flowers). Secondly, as this species has floral traits hypothesized to adapt to particular types of pollen vectors (carrion flies), we also studied the pollination of B. oxylepis to confirm whether the syndromes correspond to what occurs in nature. Through pollination treatments, we determined that all floral morphs are functional. By monitoring the inflorescences, we found that pollination is specialized in the studied population. Stingless bees performed pollination, as they have a high visitation rate, frequency, and constancy, and they are unique visitors that deposit pollen on the stigmas. Thus, they appear to be effective pollinators rather than carrion flies, as predicted by the syndrome. As shown here, animal–plant interaction studies can help establish a basis for conserving rare species such as holoparasites. Moreover, knowledge about the reproductive aspects of B. oxylepis reveals essential clues about its life cycle and role in maintaining native pollinators with economic and cultural value, such as stingless bees.

SummaryGlaciers represent important biomes of Earth and are recognized as key species pools for downstream aquatic environments. Worldwide, rapidly receding glaciers are driving shifts in hydrology, species distributions and threatening microbial diversity in glacier‐fed aquatic ecosystems. However, the impact of glacier surface snow‐originating taxa on the microbial diversity in downstream aquatic environments has been little explored. To elucidate the contribution of glacier surface snow‐originating taxa to bacterial diversity in downstream aquatic environments, we collected samples from glacier surface snows, downstream streams and lakes along three glacier‐fed hydrologic continuums on the Tibetan Plateau. Our results showed that glacier stream acts as recipients and vectors of bacteria originating from the glacier environments. The contributions of glacier surface snow‐originating taxa to downstream bacterial communities decrease from the streams to lakes, which was consistently observed in three geographically separated glacier‐fed ecosystems. Our results also revealed that some rare snow‐originating bacteria can thrive along the hydrologic continuums and become dominant in downstream habitats. Finally, our results indicated that the dispersal patterns of bacterial communities are largely determined by mass effects and increasingly subjected to local sorting of species along the glacier‐fed hydrologic continuums. Collectively, this study provides insights into the fate of bacterial assemblages in glacier surface snow following snow melt and how bacterial communities in aquatic environments are affected by the influx of glacier snow‐originating bacteria.

AbstractOur aim was to evaluate biochemical markers in plasma (NGAL, CysC) and urine (NGAL, KIM‐1) in children's early onset of acute kidney injury after congenital heart defect surgery using cardiopulmonary bypass. This study prospectively included 100 children with congenital heart defects who developed AKI. Patients with acute kidney injury had significantly higher CysC levels 6 and 12 h after cardiac surgery and plasma NGAL levels 2 and 6 h after cardiac surgery. The best predictive properties for the development of acute kidney injury are the combination (+CysCpl or +NGALu) after 12 h and a combination (+CysCpl and +NGALu) 6 and 24 h after cardiac surgery. We showed that plasma CysC and urinary NGAL could reliably predict the development of acute kidney injury. Measurement of early biochemical markers in plasma and urine, individually and combination, may predict the development of cardiac surgery‐associated acute kidney injury in children.

AbstractThis study compared endodontic access cavities prepared by operators of different experience levels (students, general‐practitioners and specialists), guided by periapical radiographs, cone‐beam computed tomography (CBCT) or 3D CBCT‐based planning software, with regards to tooth substance loss and preparation errors. Operators (n = 34) prepared endodontic access cavities in 306 three‐dimensionally printed copies of human teeth with standardised anatomies. Access cavities were volumetrically assessed post‐operative using digital scans, while preparation errors were evaluated with CBCT. Tooth substance loss was significantly influenced by the operator’s experience, being highest with students’, followed by general‐practitioners and specialists (P < 0.05), with no significant association with the employed imaging/planning modality. Pulp chamber floor, iatrogenic perforations and incomplete pulpal roof removal were insignificant between operator groups or imaging/planning modalities. It can be concluded that irrespective of advancement in imaging/planning modalities the practitioner’s experience level remains to be the decisive factor significantly influencing tooth substance loss during endodontic access cavity preparations.

AbstractThe brain is the most essential part of the central nervous system which regulates and coordinates all body activities. Based on its phylogenetic development from the neural tube, the brain is divided into rhombencephalon (hindbrain), mesencephalon (midbrain) and prosencephalon (forebrain). The present study is achieved to describe the morphological characteristics of the normal forebrain in the donkey using the matched magnetic resonance imaging (MRI) and cross‐sectional anatomy. Ten cadaveric heads of healthy adult donkeys of both sexes were used. Two heads were examined using a 1.5 Tesla MRI scanner, and the brains of the other heads were gently extracted; six brains were sectioned into transverse, dorsal and sagittal slices, and two brains were grossly inspected. MR images were selected in correlation to their closely corresponding gross sections. Both cross‐sectional anatomy and MRI scans showed extensive gyration of the neocortex. The forebrain structures appeared with variable intensities on three sequences, Flair, T1‐weighted and T2‐weighted MRI, enabling comprehensive evaluation of the relevant neuroanatomical structures. The present study provided a precise neuroanatomical atlas of the forebrain in the donkey which could help in the quick and efficient interpretation of clinical diseases of the forebrain, localization of the forebrain functions and evolutionary neurobiology.

Published: September 2021

SummaryMental health after bariatric surgery during adolescence has been little explored. This is a sensitive period in terms of self‐image on which bariatric surgery could have negative effects because of the rapid and significant changes in morphology it induces. Previous studies have explored mental effects using questionnaires and only related to psychopathological disorders. The objective of our study was to complement these studies by exploring, via in‐depth interviews, the adolescents' views on changes after bariatric surgery at psychological as well as socio‐emotional levels. Fourteen adolescents with obesity were recruited in a French hospital 6–43 months after surgery. They participated in one‐on‐one interviews lasting an average of 45 minutes. A lexical analysis (using ALCESTE software©) of their speech highlighted the most positive effects, particularly in terms of social relationships, physical activities, self‐esteem and reduced stigma, along with less positive effects in terms of eating behaviour and skin. In terms of clinical implications, this study confirmed the value of bariatric surgery for adolescents at psychological and social levels and its contribution to their mental health. However, it also highlighted the importance of pre‐ and post‐operative support.

Published: September 2021

AbstractAn organic multifunctional sensor based on a composite of nickel phthalocyanine colourant, multi‐walled carbon nanotubes and rubber is investigated in this work. The whole surface‐type device was fabricated over rubber substrate with rubbing‐in technology, including multi‐walled carbon nanotubes‐based electrodes. The proposed shockproof and flexible sensor is investigated in terms of its electric parameters, that is, its resistance and impedance, while varying the humidity (42%‐90% relative humidity), frequency (0.1‐200 kHz) and temperature (30‐68°C). The effect of each parameter is explained in depth to enhance the physics behind each outcome. The results demonstrate that impedance and resistance decrease with increases in temperature and humidity, while the sensitivity of the device decreases with an increase in frequency. These types of devices can be utilised by the medical industry for monitoring the humidity and temperature of patients while undergoing physiotherapy treatment.
On allowing for transient variation in end‐member δ13C values in partitioning soil C fluxes from net ecosystem respiration
Authors: McCloskey Christopher S. , Otten Wilfred , Paterson Eric , Kirk Guy J. D. 
Published: September 2021

AbstractThe use of stable isotope analysis to resolve ecosystem respiration into its plant and soil components rests on how well the end‐member isotope signatures (δ13C) are characterised. In general, it is assumed that end‐member values are constant over time. However, there are necessarily diurnal and other transient variations in end‐members with environmental conditions. We analyse diurnal and seasonal patterns of ecosystem respiration and its δ13C in a C4 grass growing in a C3 soil using fixed and diurnally varying plant and soil δ13C end‐members. We measure the end‐members independently, and we assess the effects of expected variation in values. We show that variation in end‐members within realistic ranges, particularly diurnal changes in the plant end‐member, can cause partitioning errors of 40% during periods of high plant growth. The effect depends on how close the end‐member is to the measured net respiration δ13C, that is, the proportion of the respiration due to that end‐member. We show light‐driven variation in plant end‐members can cause substantial distortion of partitioned soil organic matter (SOM) flux patterns on a diurnal scale and cause underestimation of daily to annual SOM turnover of approximately 25%. We conclude that, while it is not practicable to independently measure the full temporal variation in end‐member values over a growing season, this error may be adjusted for by using a diurnally varying δ13Cplant.Highlights
End‐member δ13C values used to partition ecosystem respiration vary diurnally and seasonally
Patterns of ecosystem respiration and its δ13C in a C4 grass growing in a C3 soil were analysed.
Ignoring temporal changes in end‐member δ13C values can cause large errors in partitioning
Long‐term data sets with sufficient temporal resolution can be used to correct for this
Distance factors and establishment mode choice of emerging‐market multinationals: The moderating effect of administrative distance
Authors: Rienda Laura , Quer Diego , Andreu Rosario 
Published: September 2021

AbstractRegulations, governance quality, and political structure are important factors that may alter the cost and difficulties associated with doing business in foreign markets. Emerging‐market multinationals (EMNEs), with an imperative motivation to go abroad and to be competitive in a global landscape, should consider the impact of administrative distance, namely, the regulatory institutional differences between home and host countries. We suggest that the study of administrative distance is particularly important when addressing investment flows from emerging economies to developed ones, because of the differences between them. Drawing on transaction cost theory and institutional perspective, we analyze the moderating effect of administrative distance on the relationship between other cross‐national distance factors—cultural, geographic and economic—and establishment mode choice of EMNEs. From a sample of 357 outward foreign direct investments carried out by Indian firms, our results show that administrative distance moderates the relationship between cultural, geographic and economic distance, and establishment mode decisions.
How does responsible leadership emerge? An emergentist perspective
Authors: Meliou Elina , Ozbilgin Mustafa , Edwards Tim 
Published: September 2021

AbstractIncreasing academic and practitioner conversations regarding corporate responsibility, have led some leadership scholars to question the possibilities to accomplish responsible leadership. Drawing on an emergentist perspective, through an empirical study in three organizations, the article develops the responsible leadership literature by offering a critical analysis of the emergence of responsible leadership. Our key finding is that responsible leadership emerges as participants' “shared concerns,” namely: ‘environmental and communal concerns,” “professional concerns,” “employment concerns,” and “commercial concerns,” which constitute social arrangements that give meaning to what is responsible and possible. The theoretical perspective we develop highlights the conditioning role of shared and nested concerns of the study participants and unpack how the social context variously shapes responsible leadership.
