Valuing change: differential measurement of workplace culture shift
Authors: Coutts Daniel Stewart 
Published: May 2021

PurposeMeasuring the efficacy of workplace culture-shift efforts presented a substantial challenge in the author's research exploring how culture shifts during deliberate change initiatives. In response to this challenge this conceptual article proposes that the relative value participants attribute to desired culture outcomes can function as a proxy for measuring culture shift over time, providing applied researchers and practitioners with a simple way to measure efficacy of change initiatives.Design/methodology/approachThis conceptual article reviews the difficulties of defining and measuring workplace culture using widely known, contemporary models and instruments. It then builds an argument for using differential measurement of the relative value attributed to culture shift outcomes (valuing) as a proxy for workplace culture shift, followed by discussion of how to conduct measurement.FindingsThis article deductively demonstrates that parsimonious measurement of culture shift is not only simple and feasible, but that practitioners and researchers alike can use a valuing approach to determine the efficacy of efforts to shift workplace culture.Originality/valueUsed to complement existing methods and instruments, or on its own, this approach to measurement can build deeper insights into what is going on during deliberate change initiatives, while answering the reflexive questions “are we doing the right things,” and “are we doing those things the right way?”

PurposeEnvironmental regulation policy and cleaner production technology innovation are the key links to achieve sustainable economic development. This paper tests the impact of Two Control Zone (TCZ) environmental regulation policy on cleaner production technology innovation and explains the heterogeneity effect between them from the perspective of regional pollution intensity and R&D investment scale.Design/methodology/approachThis paper takes TCZ policy as an environmental regulation policy and collects the patent data related to coal desulfurization cleaner production technology innovation in prefecture-level cities from 1994 to 2002 in China. This paper also tests the relationship between TCZ environmental regulation policy and cleaner production technology innovation based on difference in difference (DID) model. Take regional R&D investment scale and pollution intensity as category variables and analyze the heterogeneity effect of TCZ environmental regulation policy on cleaner production technology innovation based on difference-in-difference-in-difference (DDD) model.FindingsTCZ environmental regulation policy effectively promotes China's cleaner production technology innovation, but it is more conducive to cleaner production technology innovation in heavy pollution areas. With the increasing of R&D investment scale, the positive effect of TCZ environmental regulation policy on cleaner production technology innovation is stronger.Research limitations/implicationsOn the basis of this study, the authors should further explore the regulatory factors of the relationship between TCZ environmental regulation policy and cleaner production technology innovation and further expand the research object, so as to make the research conclusions more practical and instructive.Originality/valueThis paper tests the impact of TCZ environmental regulation policy on cleaner production technology innovation based on the prefecture city level data and DID model, and it handles the endogenous problem caused by the missing variables and provides the accurate conclusions. Moreover, this paper examines the heterogeneity effect of TCZ environmental regulation policy on cleaner production innovation from regional R&D investment scale and pollution intensity two hands and expands the existing theoretical research.

PurposeThe purpose of this study was to provide comprehensive overview, and exposure of the correlation between entrepreneurial orientation dimension (EOD) and business innovation environment (BIE) on small and medium enterprises (SMEs) financial performance in the Ghanaian manufacturing SMEs sector that enhances knowledge and contextualization in marketing and entrepreneurship literature.Design/methodology/approachAnchored on resource-based view theory, 520 manufacturing SMEs companies were conveniently drawn from Association of Ghana Industry, through National Board for Small Scale Industries, using structural equation modelling techniques to analyse the hypotheses.FindingsThis study revealed that three entrepreneurial orientation dimensions EOD: risk-taking, innovations and pro-activeness have positive significant impact on financial performance manufacturing of SMEs. BIE also has positive impact on financial performance of manufacturing of SMEs and BIE moderates SMEs financial performance.Research limitations/implicationsThis is a country-specific manufacturing SMEs sector, which means that the findings cannot be used to justify other SMEs in Ghana and SMEs in different country. However, the study was limited to only three EODs: risk-taking, innovations, pro-activeness and Ghanaian manufacturing BIE of SMEs. More countries and other SMEs are needed to expand the field of research in EODs and BIE.Practical implicationsIt provides an insight into BIE which is important for marketers, entrepreneurs, regulatory bodies, SMEs owners-managers, directors, government and NGO to strengthening and reshaping their BIE in manufacturing SMEs sector policies, conducts and laws.Originality/valueThis paper fills knowledge and contextual gap in entrepreneurship and marketing literature by presenting comprehensive overview of BIE and EOD research that enhances the on-going discussion in the marketing and entrepreneurship manufacturing SMEs context and proposing priorities for future research streams within an emerging economy.
Sequential joint inversion of gravity and magnetic data via the cross‐gradient constraint
Authors: Tavakoli Mojtaba , Nejati Kalateh Ali , Rezaie Mohammad , Gross Lutz , Fedi Maurizio 
Published: May 2021

ABSTRACTDifferent geophysical methods use different model parameterizations and inversion algorithms. Thus, combining these different inversion systems and yet adding the nonlinear cross‐gradient constraint in a joint inversion framework might be a big challenge, for instance, as explained further by Moorkamp et al. in 2011, there is a complex interaction between the data misfit terms, regularization and cross‐gradient terms and an imperfect fit to the data is expected. In this paper, we use a sequential algorithm for a two‐dimensional joint inversion of gravity and magnetic data, which tries to avoid these issues by decoupling the gravity inversion, the magnetic inversion and the cross‐gradient minimization processes. The efficiency of the algorithm and developed code is demonstrated by the joint inversion of noisy synthetic data. The results show a significant improvement in the respective models obtained by introducing the cross‐gradient joint inversion over the models obtained by separate inversions for synthetic data and then for field data targeting potash ore source in the AjiChai salt deposit in north‐western Iran.In this application case, the lower density of salt minerals such as potash, compared to its surrounding sedimentary sequences, motivates a gravity study. Furthermore, the relative lower susceptibility of these salt minerals, alongside their diamagnetic effect, makes them a suitable target for magnetic surveys. Separate gravity and magnetic studies had been performed over the deposit; however, a constitutive relationship between density and magnetization within the area of interest supporting a joint inversion had not been established. In this paper, we apply the sequential cross‐gradient approach to perform the first full joint inversion for the AjiChai salt deposit. The magnetic inversion here is performed to recover the magnetization amplitudes rather than the magnetization vector. In fact, we assume there is no remanent magnetization and, therefore, that the magnetization vector is constant and parallel to the geomagnetic field direction. The constructed density and magnetization models are of high concordance with available geological information and previous studies including drilling results. In addition, unlike previous separate inversion models, the models are structurally and geometrically similar.
Financial inclusion and entrepreneurship willingness of youth: Evidence from Mali
Authors: Koloma Yaya 
Published: May 2021

AbstractThis study examines the determinants of youth financial inclusion and its impacts on their willingness to become entrepreneurs in Mali. The World Bank's Global Findex database is used to perform Logit estimations and propensity score matching. We find that the financial inclusion of youth seems to be more determined by the attainment of a high level of education, employment status, living in a wealthy family, and having at least one family member with a bank account. Three factors appear as barriers to better financial inclusion of youth: the cost of financial services, the lack of money, and the perception that financial services, savings in particular, are not a necessity. The study also shows that savings and loans have a statistically significant impact on the willingness to engage in entrepreneurial activity, even in the agricultural sector. Particularly for young people, providing them with loan services seems to have more impact than other financial services on the desire to undertake agri‐entrepreneurial activity. The study recommends the strengthening of public policies aimed at expanding credit to youth because of its high impact on their willingness to engage in entrepreneurship in general and in agri‐preneurship in particular in Mali.
Alternative Finance after Natural Disasters
Authors: Baltas Konstantinos , Fiordelisi Franco , Mare Davide S. 
Published: May 2021

AbstractIn this paper, we show that alternative finance (e.g. private equity, crowdfunding and venture capital) is a key source of funding for firms that are affected by natural disasters. Using data on a large sample of US companies from 2010 to 2019, we provide robust empirical evidence that private funding increases within 3 months after the occurrence of a natural disaster. Panel data analysis at state level shows that extreme events cause at least an average increase of funding from alternative finance by 47% relative to firms in non‐affected states. We also find that size, reliance on physical assets and age improve access to alternative finance after adverse natural events. Our empirical evidence highlights the key role of private lenders in providing financial resources to affected firms after extreme exogenous events.
TheFantasticschool: Catherine Malabou and an ontological basis in defence of the school
Authors: Oral Sevket Benhur 
Published: May 2021

AbstractIn their defence of the school Jan Masschelein and Maarten Simons define it as a source of ‘free time.’ Drawing on Catherine Malabou's compelling reading of Heidegger in her The Heidegger Change, I aim to provide a strong ontological justification for the claims made on behalf of the school concerning free time, common goods, and renewing (changing) the world: the school provides free time; it transforms knowledge and skills into common goods; and it has the potential to give everyone the time and space to renew the world. The paper enquires into what ‘free time as non-productive time,’ ‘common goods,’ and ‘changing the world’ mean on an ontological register, and why therefore the school is so precious and warrants our utmost care in the face of its conservative and progressive critics alike. I discern a single underlying notion, the notion of essence as mutability, constituting the link connecting free time, common goods, and renewal of the world.

In total, 26 076 women reported doing the medical abortion, of whom 1.5% reported an ongoing pregnancy, 10.2% a surgical intervention and 0.6% a blood transfusion. Acceptability of the service was 99%, and 59.2% of the users reported previous knowledge of medical abortion. We found a significant increase in complete abortions in 2019 (odds ratio 1.92; 95% CI 1.59–2.31) and decrease in surgical interventions (odds ratio 0.49; 95% CI 0.40–0.60) compared with 2009.ConclusionLow follow‐up rates present a limitation in analysing trends in telemedical abortion usage. However, our findings suggest that it is a highly acceptable method around the world and that there has been an increase in complete abortions by telemedical abortions and a decrease in surgical interventions in the last 10 years.Tweetable abstractIn the last 10 years, there has been an increase in complete abortions and decrease in surgical interventions of telemedical abortion.
Two dehydroecdysone reductases act as fat body‐specific 20E catalyzers in Bombyx mori

Published: May 2021

AbstractPeriodic post‐embryonic changes in insects, including growth, development and metamorphosis, are strictly controlled by many compounds, including steroid hormones. The biosynthesis and clearance of 20‐hydroxyecdysone (20E), the major active form of the insect steroid hormone ecdysone, result in titer fluctuations that help control insect development. The inactivation of 20E in the silkworm Bombyx mori is highly tissue‐specific, with CYP18A1 and ecdysone oxidase controlling 20E inactivation specifically in the mid‐silk gland and midgut, respectively. Here, we characterized silkworm 3‐dehydroecdysone 3α reductase (Bm3DE3α) and 3‐dehydroecdysone 3β reductase (Bm3DE3β), two enzymes involved predominantly in the C‐3‐mediated catalysis of 20E in fat bodies. The ubiquitous and silk gland‐specific overexpression of Bm3DE3α decreased the 20E titer, resulting in larval lethality and larval–pupal transition failure, respectively. In contrast, the ubiquitous and mid‐silk gland‐specific overexpression of Bm3DE3β increased the 20E titer, resulting in larval growth delays and lethality at the mid‐fifth larval stage, respectively. Thus, Bm3DE3α and Bm3DE3β mediate fat body‐specific steroid hormone metabolism in B. mori, indicating that highly diversified 20E metabolism‐related mechanisms exist in different insect species.

Published: May 2021

AbstractHydraulic conductivity (K) is a key hydrologic parameter widely recognized to be difficult to estimate and constrain, with little consistent assessment in disturbed, urbanized soils. To estimate K, it is either measured, or simulated by pedotransfer functions, which relate K to easily measured soil properties. We measured K in urbanized soils by double‐ring infiltrometer (Kdring), near‐saturated tension infiltrometry (Kminidisk), and constant head borehole permeametry (Kborehole), along with other soil properties across the major soil orders in 12 United States cities. We compared measured K with that predicted from the pedotransfer function, ROSETTA. We found that regardless of soil texture, Kdring was consistently larger than Kminidisk; with the latter having slightly less sample variance. Kborehole was dependent upon specific subsurface conditions, and contrary to common expectations, did not always decrease with depth. Based on either soil textural class, or percent textural separates (sand, silt clay), ROSETTA did not accurately predict measured K for surface nor subsurface soils. We go on to discuss how K varies in urban landscapes, the role of measurement methods and artifacts in the perception of this metric, and implications for hydrologic modeling. Overall, we aim to inspire consistency and coherence when addressing K‐related challenges in sustainable urban water management.
Assessment of Aquifer Storage and Recovery Feasibility Using Numerical Modeling and Geospatial Analysis: Application in Louisiana

Published: May 2021

AbstractAquifer storage and recovery (ASR) is a solution for regions experiencing groundwater shortages, but is unexplored in wet regions such as Louisiana, which is experiencing aquifer overdrafting at alarming rates. Surface storage reservoirs are infeasible in these low‐gradient environments, so ASR can provide an alternative to alleviate groundwater stress and prevent subsidence and saltwater intrusion. The purpose of this study was to assess the feasibility of ASR in the Chicot Aquifer in Southwest Louisiana. The study is based on a regional groundwater model combined with a geospatial analysis of the quantity and quality of surface water and groundwater resources and land use. A statistical distribution was used to rate each criterion and combine them into a suitability index (SI) that defines each watershed’s feasibility considering combinations of criteria determined by the user’s purpose for ASR and the availability of data. The SI was formulated as a hybrid additive‐multiplicative function to provide flexibility in specifying criteria that are deemed most constraining for ASR feasibility. The analysis identified the east‐central zone of the Chicot Aquifer, which is experiencing substantial groundwater stress from agricultural irrigation, as most suited for ASR operations. Besides the criteria on water availability and aquifer characteristics, the quality of the surface water and land‐use considerations were key factors in constraining the feasible watersheds.

AbstractBackgroundA systematic review showed limited associations between pregnancy diet and offspring allergy. We developed a maternal diet index during pregnancy that was associated with offspring allergy outcomes.MethodsData came from Healthy Start, a Colorado pre‐birth cohort of mother/offspring dyads. Food propensity questionnaires were completed during pregnancy. Offspring allergic rhinitis, atopic dermatitis, asthma, wheeze, and food allergy diagnosis up to age four were verified from electronic medical records. Data were randomized into test and replication sets. The index included the weighted combination of variables that best predicted a combined outcome of any allergy in the test set. Index utility was verified in the replication set. Separate adjusted and unadjusted logistic models estimated associations between the index and each offspring allergy diagnosis in the full sample.ResultsThe index included weighted measures of intake of vegetables, yogurt, fried potatoes, rice/grains, red meats, pure fruit juice, and cold cereals. Vegetables and yogurt were associated with the prevention of any allergy, while other components were associated with increased disease. In adjusted models, a one‐unit increase in the index was significantly associated with reduced odds of offspring allergic rhinitis (odds ratio (CI) 0.82 [0.72–0.94]), atopic dermatitis (0.77 [0.69–0.86]), asthma (0.84 [0.74–0.96]), and wheeze (0.80 [0.71–0.90]), but not food allergy (0.84 [0.66–1.08]).ConclusionsThis is the first study that has shown associations between an index of maternal dietary intake during pregnancy and multiple offspring allergic diseases. The results give hope for prevention of allergic diseases in utero.
