How store managers’ employee climate perceptions affect frontline employee, customer and store performance outcomes: an examination in the small-store setting
Authors: Deitz George , Hansen John D. , DeCarlo Tom , Babakus Emin 
Published: June 2021

PurposeThe purpose of this paper is to examine the effects of store managers’ employee climate perceptions on frontline employee (FLE), customer and store performance outcomes in the small-store setting.Design/methodology/approachThis study derives the findings from a multi-source data set acquired in partnership with a North American-based retailer that includes survey responses from 1,133 store managers, 5,591 FLEs and 16,488 customers. This paper matches survey responses to corporate records and store sales and operations data.FindingsThis study finds that store managers’ employee climate perceptions affect FLEs both directly and indirectly, through store manager social support behaviors. This paper tests the boundary conditions for these findings by examining the moderating effects of store-level FLE tenure heterogeneity and competitive intensity. Study results provide partial support for the hypothesized relationships with regard to FLE tenure heterogeneity, but not competitive intensity.Research limitations/implicationsThis research is subject to many of the limitations common to a survey-based study. While the use of one retailer provided opportunities to examine store-level performance data, future research would benefit by using a more expansive data set spanning several companies and industries. Moreover, as the current study was set in the small-store setting, future research should explore how store managers’ influence fluctuates depending on store size and the mechanisms through which organizational priorities flow through other management levels (e.g. department managers) in large retailers.Practical implicationsStudy results provide managerial guidance regarding the implementation of an employee climate for the delivery of an enhanced customer experience and superior financial performance.Originality/valueAlthough researchers have paid considerable attention to employees’ psychological and organizational climate perceptions, this study makes a unique contribution by examining the effects of store managers’ employee climate perceptions on FLE, customer and store-level outcomes.

Land and clean energy trade-off: estimating India’s future land requirement to fulfil INDC commitment
Authors: Rej Soumen , Nag Barnali 
Published: June 2021

Purpose
For India, with its low agricultural productivity and huge population, land acquisition has always been a serious policy challenge in the installation of land-intensive power projects. India has experienced a large number of projects getting stalled because of land conflict. Yet, there is a paucity of literature pertinent to India that tries to estimate future land requirements taking into consideration of land occupation metric.

Design/methodology/approach
In the present study, the dynamic land transformation and land occupation metrics of nine energy sources, both conventional and renewable, are estimated to further determine the magnitude of land requirement that India needs to prepare itself to fulfil its Intended Nationally Determined Contribution (INDC) commitments. This is illustrated through two different scenarios of energy requirement growth rates, namely, conservative and advanced.

Findings
This analysis suggests that, while nuclear energy entails the lowest dynamic land transformation when land occupation metric is taken into account, waste to energy source possesses least land requirement, followed by coal-fired source. Hydro energy source has highest requirement both in terms of dynamic land transformation and land occupation. It is also seen that land requirement will be 96% and 120% more in INDC scenario than business as usual (i.e. if India continues with its current share of renewables in its energy portfolio in 2030) considering a conservative and an advanced growth rate, respectively.

Research limitations/implications
Some policy recommendations are provided that may aid policymakers to better address the trade-off between clean energy and land and incorporate it into policy planning. This study has not been able to consider future technical efficiency improvement possibilities for all energy sources, which can be incorporated in the proposed framework for further insight.

Originality/value
This paper provides a framework for estimation of future land requirement to fulfil India’s INDC energy plans which is not available in existing literature. The authors confirm that this manuscript is an original work.
The effect of lean on performance: a longitudinal study of US Hospitals
Authors: Zhang Huilan 
Published: June 2021

PurposeThere has been little empirical research focused on the effect of lean on hospital performance in the form of a consolidated methodology. This paper aims to apply a more sophisticated approach to examine whether hospitals’ decision for lean implementation is endogenous and test the effects of lean on hospital performance.Design/methodology/approachThis study uses a publicly available data set of hospitals across the USA from 2002 to 2019 and performs two-stage least squares (2SLS) analysis. In the first stage, a probit model is used to estimate hospitals’ decision to implement lean. The fitted probability values from the first stage are used in the second stage to test the relationship between lean and hospital performance. Ordinary least squares (OLS) regression results are compared with those of the 2SLS approach.FindingsThe decision to implement lean is significantly associated with hospital-specific characteristics (the complexity of care, size and cost-to-charge ratio), indicating hospitals’ decision for lean implementation is endogenous. Moreover, there is strong evidence that lean implementation is positively associated with hospital financial and operational performance. The Hausman F-tests confirm the presence of endogeneity and this, in turn, suggests that OLS regressions result in unreliable estimates.Practical implicationsThe findings of this study can help hospital managers benchmark performance and explore opportunities for profit and efficiency improvement. The findings are also relevant to policymakers who strive to lower health-care spending.Originality/valueThis study is motivated by the challenges facing the health-care industry. This study is among the first to investigate endogeneity in lean implementation and the association between lean and hospital performance using large-scale archival panel data. The use of the 2SLS approach provides more confidence in statistical findings.
Does corporate political party ideology matter? Evidence from bank loan contracts
Authors: Na HyunJun 
Published: June 2021

Purpose
This paper aims to examine how a firm’s political party orientation (Republican or Democratic), which is measured as the composite index based on the political party leanings of top managers, affects bank loan contracts. This study also investigates how the political culture of local states has a significant impact on loan contracts.

Design/methodology/approach
This research uses various databases including the Loan Pricing Corporation’s DealScan database, financial covenant violation indicators based on the Securities and Exchange Commission (SEC) filings, firm bankruptcy filings and political culture index data to examine the impact of political orientation on the cost of debt. This paper also includes the state level of gun ownership and bachelor’s degrees to investigate how local political culture affects the loan contract. To control endogenous concerns, this paper uses an instrumental variable analysis.

Findings
Firms that have Republican-oriented political identities pay lower yield spreads for the main costs of debt including all-in-spread-drawn and all-in-spread-undrawn. This pattern is consistent with other fees of bank loans. This paper finds that an increase in conservative political policies toward Republican orientations is negatively associated with the cost of debt. The main findings also show that the political culture in the state where the headquarters of the borrowing firm are located plays an important role in bank loan contracts.

Originality/value
The findings in this paper provide evidence that a firm’s political party orientation significantly affects the loan contract terms in both pricing and non-pricing terms. To the best of the author’s knowledge, this is the first study that shows the importance of political party identification on loan contracts by separating the sample into Republican, neutral and Democratic.

Authors: Yılmaz Mustafa Safa , Özer Gökhan , Öter Zafer Çağatay , Ertuğrul Onur 
Published: June 2021

Purpose
This paper aims to investigate the effects of various heat treatments on microstructure, hardness, porosity and corrosion properties of the parts.

Design/methodology/approach
Hot isostatic pressing (HIP) process, various heat treatments and their combinations were applied to the AlSi10Mg parts produced by direct laser metal sintering (DMLS).

Findings
It has been found that the HIP process, which is a post-processing process, reduces the amount of porosity in DMLS-AlSi10Mg material, thus improves corrosion resistance significantly.

Originality/value
In this study, the HIP process and subsequent T6 heat treatments were applied to AlSi10Mg parts produced by the DMLS technique. The study aims to increase the corrosion resistance of AlSi10Mg parts by reducing porosity with the HIP process and by altering the microstructure with the T6 process.

Abstract

Free‐air carbon dioxide enrichment (FACE) experiments in terrestrial ecosystems have demonstrated ecological responses of key ecosystem processes to rising atmospheric carbon dioxide (CO2). However, CO2 fertilization responses in field conditions have seldom included methane (CH4) and nitrous oxide (N2O), particularly in natural and mature forests, which are expected to have an important role in climate change mitigation.

Herein, we aimed to capture the effect of elevated CO2 (eCO2; ambient vs. +150 ppm) on long‐term temporal dynamics of CH4 and N2O fluxes, followed by identification of climo‐edaphic factors explaining feedback responses. To achieve this, continuous monitoring of greenhouse gas (GHG) fluxes using a manual chamber technique, over a 3‐year period was implemented in a mature dryland Eucalypt forest FACE (EucFACE) facility in Australia. The relationship between CH4 and N2O fluxes with rainfall indices and soil properties was also explored since they directly impact the microbial communities in the soil responsible for CH4 and N2O net emissions.

Our results showed that in 3 years of eCO2 treatment, the amount and frequency of rainfall predicted GHG emissions in this native forest. We also found a significant reduction in CH4 sink (15%–25%) for some of the years as well as an overall treatment effect index reduction in N2O emissions under eCO2. Higher frequency of rain events with lower intensity led to highest CH4 sink followed by lowest N2O emissions due to fewer wet–dry cycles. Of all the environmental variables included, soil moisture, rainfall and pH were the main predictors of net CH4 and N2O emissions. Methane flux was also strongly influenced by soil texture.

Our findings highlight the need to account for reduced forest CH4 sink under eCO2 in dryland ecosystems, which has implications for GHG budget predictions under future climate conditions.

Sweet tooth: DNA profiling of a cranium from an isolated retained root fragment
Authors: Chierto Elena , Cena Greta , Mann Robert W. , Mattutino Grazia , Nuzzolese Emilio , Robino Carlo 
Published: June 2021

AbstractSampling of healthy multi‐rooted teeth is recommended for the genetic identification of human skeletal remains. However, this may not always be possible, as in the reported case consisting of an isolated human cranium found in an aggregate crushing and processing plant in Piedmont, Northwest Italy. The cranium displayed significant weathering, suggesting a post‐mortem interval of several years, and was edentulous with the exception of the apical root fragment of the upper left canine, consequence of an antemortem horizontal fracture. Prolonged decalcification of the root fragment followed by powder‐free DNA extraction from ~10 mg of root tip tissue led to the recovery of >10 ng of high molecular weight human DNA, in comparison with ~0.01 ng of DNA per mg of bone powder obtained from the petrous portion of the temporal bone. Quantity and quality of DNA isolated from apical tooth tissue enabled multiple genotyping, including a reportable female STR profile, mitochondrial DNA analysis, and ancestry‐informative insertion/deletion polymorphisms. Although the cranium remained unidentified after DNA comparisons, our findings confirm that apical tooth tissue is a promising source of DNA, easily obtained through a powder‐free extraction protocol. Results also indicate that root tips should not be overlooked in challenging identification cases, even in the presence of compromised tooth specimens.
Opening a next‐generation black box: Ecological trends for hundreds of species‐like taxa uncovered within a single bacterial >99% 16S rRNA operational taxonomic unit
Authors: Hahn Martin W. , Huemer Andrea , Pitt Alexandra , Hoetzinger Matthias 
Published: June 2021

AbstractCurrent knowledge on environmental distribution and taxon richness of free‐living bacteria is mainly based on cultivation‐independent investigations employing 16S rRNA gene sequencing methods. Yet, 16S rRNA genes are evolutionarily rather conserved, resulting in limited taxonomic and ecological resolutions provided by this marker. The faster evolving protein‐encoding gene priB was used to reveal ecological patterns hidden within a single operational taxonomic unit (OTU) defined by >99% 16S rRNA sequence similarity. The studied subcluster PnecC of the genus Polynucleobacter represents a ubiquitous group of abundant freshwater bacteria with cosmopolitan distribution, which is very frequently detected by diversity surveys of freshwater systems. Based on genome taxonomy and a large set of genome sequences, a sequence similarity threshold for delineation of species‐like taxa could be established. In total, 600 species‐like taxa were detected in 99 freshwater habitats scattered across three regions representing a latitudinal range of 3,400 km (42°N to 71°N) and a pH gradient of 4.2 to 8.6. In addition to the unexpectedly high richness, the increased taxonomic resolution revealed structuring of Polynucleobacter communities by a couple of macroecological trends, which was previously only demonstrated for phylogenetically much broader groups of bacteria. An unexpected pattern was the almost complete compositional separation of Polynucleobacter communities of Ca2+‐rich and Ca2+‐poor habitats. This compositional pattern strongly resembled the vicariance of plant species on silicate and limestone soils. The new cultivation‐independent approach presented opened a window to an incredible, previously unseen diversity, and enables investigations aiming on deeper understanding of how environmental conditions shape bacterial communities and drive evolution of free‐living bacteria.

Published: June 2021

SummaryThe objectives of this study were to provide the buffalo research community with an updated SNP map for the Axiom Buffalo Genotyping (ABG) array with genomic positions for SNP currently unmapped and to map all cattle QTL from the CattleQTLdb onto the buffalo reference assembly. To update the ABG array map, all SNP probe sequences from the ABG array were re‐aligned against the UOA_WB_1 assembly. With the new map, the number of mapped markers increased by approximately 10% and went from 106 778 to 116 708, which reduced the average marker spacing by approximately 2 kb. A comparison of results between signatures of autozygosity study using the ABG and the new map showed that, when the additional markers were used there was an increase in the autozygosity peaks and additional peaks in BBU5 and BBU11 could be identified. After sequence alignment and quality control, 64 650 (UMD3.1) and 76 530 (ARS_UCD1.2) cattle QTL were mapped onto the buffalo genome. The mapping of the bovine QTL database onto the buffalo genome should be useful for genome‐wide association studies in buffalo and, given the high homology between the two species, the positions of cattle QTL on the buffalo genome can serve as a stepping stone towards a water buffalo QTL database.

Published: June 2021

AbstractBackground/ObjectivesIn recent years, there is a growing incidence of granulomatous lobular mastitis (GLM), but studies about the coexistence of erythema nodosum (EN) and GLM are rare. In this study, we assess the clinical characteristics and predictive factors of EN in GLM.MethodsA total of 303 patients diagnosed with GLM were enrolled from January 2012 to October 2018 at the second affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, including 78 patients with EN. Follow‐up data included: lesion site, lesion size, therapy approaches, course of GLM, course of EN, the recurrence of disease, possible causes. All patients had pathologic confirmation of GLM based on core needle biopsy (CNB) or surgical excision.ResultFever in the EN group was significantly more common compared to the non‐EN group (44.87% vs 12.89%, P < 0.001). The proportion of lesion range >2 quadrants in the EN group was significantly higher than that in the non‐EN group (42.31% vs 16.00%, P < 0.001). The course of the disease was longer in the EN group compared to the non‐EN group (10.32 moths vs 8.74 moths, P < 0.001). Patients with EN had a trend towards a higher risk of recurrence (5.13% vs 1.33%, P = 0.055).ConclusionEN is more likely to be found in GLM patients with breast lesion range >2 quadrants. The presence of EN in GLM indicates that the condition becomes more severe and the course of GLM also becomes longer.
Miliaria crystallina induced by idarubicin and all‐trans‐retinoic acid: Two case reports
Authors: Valenzuela‐Ubiña Sandra , Villegas‐Romero Isabel , Jiménez‐Gallo David , Arjona‐Aguilera Cintia , Linares‐Barrios Mario 
Published: June 2021

AbstractMiliaria crystallina is a benign, self‐limiting disorder of the eccrine sweat glands characterized by the obstruction of the sweat ducts, which leads to secondary sweat retention into stratum corneum. We present two patients with MC during treatment with idarubicin and all‐trans‐retinoic acid (ATRA) for acute promyelocytic leukaemia (APL). Anthracyclines can be excreted through sweat and induce MC through exfoliation. The use of idarubicin in combination with ATRA would favour the process of producing a peeling effect. Reports of MC associated with idarubicin and ATRA are scarce. Recognizing this benign entity and its triggers will help to differentiate it from other skin reactions, improving the management of patients by avoiding unnecessary studies and treatments.
