Does officer self-legitimacy mediate the linkage between internal and external procedural justice? Evidence from Taiwanese police officers
Authors: Chen Fei-Lin , Sun Ivan , Wu Yuning , Wang Shun-Yung Kevin 
Published: June 2021

PurposeThis paper aims to assess whether internal procedural justice is directly and indirectly through self-legitimacy connected to external procedural justice among Taiwanese police officers.Design/methodology/approachSurvey data used in this study were collected from 316 Taiwanese police officers in 2019. Structural equation modeling was performed to examine the direct and indirect relationships between internal and external procedural justice.FindingsSupervisors' internal procedural justice is directly related to the external procedural justice rendered to the public by police officers. Internal procedural justice also directly enhances officers' perceptions of internal legitimacy and external legitimacy. Greater senses of internal legitimacy are then accompanied by higher external procedural justice.Research limitations/implicationsSurvey data collected from a non-random sample of officers limit the study findings' generalizability. Organizational justice in the form of supervisory justice is instrumental in promoting officers' perception of self-legitimacy and their delivery of fair treatment to the public.Originality/valueThe present study represents a first attempt to link two important veins of studies in recent policing literature, organizational justice and officer self-legitimacy. This study provides needed evidence to support the value of supervisory justice in policing in a non-Western democracy.
Ownership concentration, foreign ownership and tunneling in Indonesia
Authors: Wulandari Trisninik Ratih , Setiawan Doddy 
Published: June 2021

PurposeThis study aims to examine the effect of ownership concentration and foreign ownership on tunneling activities in Indonesia.Design/methodology/approachThe population in this study were manufacturing companies listed on the Indonesian Stock Exchange from 2014 to 2018. The total observations used in this study were 557 observations. This study used three measurements to assess tunneling activities in a company, namely, related party receivables (TUL1), related party payables (TUL2) and related party receivables-payables (TUL3).FindingsThe results of this study indicated that ownership concentration and foreign ownership had a negative effect on tunneling activity of TUL1. Meanwhile, the effect of ownership concentration and foreign ownership on TUL2 and TUL3 showed a positive effect. This indicated that manufacturing companies in Indonesia preferred to carry out tunneling activities through related party payables compared with related party receivables. Foreign ownership was also effective in controlling the company’s tunneling activities when the company conducted tunneling transactions of related party receivables. Small companies and companies with positive return on assets were more susceptible to tunneling activities carried out by the companies.Practical implicationsThe results of this study can be used as a consideration for investors in making decisions by looking at tunneling activities carried out by companies in Indonesia.Originality/valueTo the best of the authors’ knowledge, no previous study in the tunneling literature has compared the results of the effect of the concentration of foreign ownership and ownership on tunneling using three measurements at once. This is useful to see the company’s behavior of tunneling activities from a different perspective.
Characteristics of supplier performance measurement systems in collaborative innovation projects: the role of the purchasing department
Authors: Patrucco Andrea , Frattini Federico , Di Benedetto Anthony 
Published: June 2021

Purpose
In the wake of the growing popularity of the open innovation approach, leveraging suppliers as external sources of innovation has attracted increasing interest from scholars and practitioners. Successful supplier involvement largely depends on an effective performance measurement process, but both supply chain management and innovation management literature have paid limited attention to this aspect. This paper aims to fill this gap by illustrating how companies measure the performance of the suppliers involved in their innovation projects and what role is played by the purchasing department.

Design/methodology/approach
This study interviews project stakeholders from nine different organizations acting as focal companies in the supply chains of various industries. This paper complements this on-field information with a vast amount of data collected from secondary project documents. Structured data coding and analysis allow us to discuss how companies redesign their performance measurement systems to ease the collaboration with suppliers in innovation and what factors underly these decisions.

Findings
The findings show that, in many cases, supplier performance measurement systems deviate from their typical characteristics to support collaboration in innovation projects. They integrate quantitative and qualitative measures, include contributions from different project stakeholders and are oriented toward high visibility and transparency with suppliers. A more substantial redesign of these systems is favored when purchasing is assigned to strategic project responsibilities and possesses higher absorptive capacity.

Originality/value
The results complement the knowledge for the supply chain management field, where supplier performance measurement systems have been discussed in the context of traditional buyer-supplier relationships, but not comprehensively in innovation projects and not considering the role of purchasing. Findings also contribute to the innovation management literature, which has mostly focused on what aspects need to be measured for innovation partners, rather than how to manage the performance measurement process in practice.
Do third-party assurance and mandatory CSR reporting matter to philanthropic and financial performance nexus? Evidence from India
Authors: Oware Kofi Mintah , Valacherry Arunima Kambikkanon , Mallikarjunappa Thathaiah 
Published: June 2021

Purpose
The purpose of this study is to focus on examining whether third-party assurance (TPA) and mandatory corporate social responsibility reporting (MCSR) matter in the association between philanthropic giving (PHG) and listed firms’ financial performance.

Design/methodology/approach
Using the Indian stock market as a testing ground, the study used interactive regression and panel regression to analyse 80 sustainability-reporting firms with 800 firm-year observations between 2010 and 2019.

Findings
The first findings show a positive association between PHG and financial performance (return on assets, ROA and stock price returns, SPR). Also, the study shows that the interactive variable of MCSR and PHG has a mixed association with financial performance. The second findings show a positive and statistically significant association between TPA and SPR. Also, the interactive effect of TPA and PHG has a negative association with return on equity (ROE) and a positive association with SPR. The third findings show a negative association between MCSR and financial performance (ROA and ROE) and a positive association with SPR. However, when a firm combines MCSR and TPA, the outcome is a negative association with ROE. The fourth findings show that MCSR has a positive association with TPA. The study control for any form of heteroscedasticity, serial correlation and endogeneity effects.

Practical implications
Managers, if given a choice, must opt for TPA over MCSR because the βcoefficient is higher in TPA than MCSR in PHG-financial performance nexus.

Originality/value
The study addresses the information asymmetry problem from the application of TPA and MCSR, which is new to an emerging economy context.
13C‐chloromethane incubations provide evidence for novel bacterial chloromethane degraders in a living tree fern

Published: June 2021

SummaryChloromethane (CH3Cl) is the most abundant halogenated volatile organic compound in the atmosphere and contributes to stratospheric ozone depletion. CH3Cl has mainly natural sources such as emissions from vegetation. In particular, ferns have been recognized as strong emitters. Mitigation of CH3Cl to the atmosphere by methylotrophic bacteria, a global sink for this compound, is likely underestimated and remains poorly characterized. We identified and characterized CH3Cl‐degrading bacteria associated with intact and living tree fern plants of the species Cyathea australis by stable isotope probing (SIP) with 13C‐labelled CH3Cl combined with metagenomics. Metagenome‐assembled genomes (MAGs) related to Methylobacterium and Friedmanniella were identified as being involved in the degradation of CH3Cl in the phyllosphere, i.e., the aerial parts of the tree fern, while a MAG related to Sorangium was linked to CH3Cl degradation in the fern rhizosphere. The only known metabolic pathway for CH3Cl degradation, via a methyltransferase system including the gene cmuA, was not detected in metagenomes or MAGs identified by SIP. Hence, a yet uncharacterized methylotrophic cmuA‐independent pathway may drive CH3Cl degradation in the investigated tree ferns.
Growth promotion of a deep‐sea bacterium by sensing infrared light through a bacteriophytochrome photoreceptor
Authors: Liu Ge , Shan Yeqi , Zheng Rikuan , Liu Rui , Sun Chaomin 
Published: June 2021

SummaryPhotoreceptors are found in all kingdoms of life and bacteriophytochromes (Bphps) are the most abundant photo‐sensing receptors in bacteria. Interestingly, BphPs have been linked to some bacterial physiological responses, yet most of the biological processes they regulate are still elusive, especially in non‐photosynthetic bacteria. Here, we show that a bacteriophytochrome (CmoBphp) from a deep‐sea bacterium Croceicoccus marinus OT19 perceives infrared light (wavelength at 940 nm) and transduces photo‐sensing signals to a downstream intracellular transduction cascade for better growth. We discover that the infrared light‐mediated growth promotion of C. marinus OT19 is attributed partly to the enhancement of pyruvate and propanoate metabolism. Further study suggests that CmoBphp plays a crucial role in integrating infrared light with intracellular signalling to control the bacterial growth and metabolism. This is the first report that deep‐sea non‐photosynthetic bacteria can sense infrared light to control growth through a bacteriophytochrome photoreceptor, thus providing new understandings towards light energy utilization by microorganisms.
The landscape of lysogeny across microbial community density, diversity and energetics
Authors: Silveira Cynthia B. , Luque Antoni , Rohwer Forest 
Published: June 2021

SummaryLysogens are common at high bacterial densities, an observation that contrasts with the prevailing view of lysogeny as a low‐density refugium strategy. Here, we review the mechanisms regulating lysogeny in complex communities and show that the additive effects of coinfections, diversity and host energic status yield a bimodal distribution of lysogeny as a function of microbial densities. At high cell densities (above 106 cells ml−1 or g−1) and low diversity, coinfections by two or more phages are frequent and excess energy availability stimulates inefficient metabolism. Both mechanisms favour phage integration and characterize the Piggyback‐the‐Winner dynamic. At low densities (below 105 cells ml−1 or g−1), starvation represses lytic genes and extends the time window for lysogenic commitment, resulting in a higher frequency of coinfections that cause integration. This pattern follows the predictions of the refugium hypothesis. At intermediary densities (between 105 and 106 cells ml−1 or g−1), encounter rates and efficient energy metabolism favour lysis. This may involve Kill‐the‐Winner lytic dynamics and induction. Based on these three regimes, we propose a framework wherein phage integration occurs more frequently at both ends of the host density gradient, with distinct underlying molecular mechanisms (coinfections and host metabolism) dominating at each extreme.
Biochemistry of methanol‐dependent acetogenesis in Eubacterium callanderi KIST612
Authors: Dietrich Helge M. , Kremp Florian , Öppinger Christian , Ribaric Luna , Müller Volker 
Published: June 2021

SummaryMethanol is the simplest of all alcohols, is universally distributed in anoxic sediments as a result of plant material decomposition and is constantly attracting attention as an interesting substrate for anaerobes like acetogens that can convert bio‐renewable methanol into value‐added chemicals. A major drawback in the development of environmentally friendly but economically attractive biotechnological processes is the present lack of information on biochemistry and bioenergetics during methanol conversion in these bacteria. The mesophilic acetogen Eubacterium callanderi KIST612 is naturally able to consume methanol and produce acetate as well as butyrate. To grasp the full potential of methanol‐based production of chemicals, we analysed the genes and enzymes involved in methanol conversion to acetate and identified the redox carriers involved. We will display a complete model for methanol‐derived acetogenesis and butyrogenesis in Eubacterium callanderi KIST612, tracing the electron transfer routes and shed light on the bioenergetics during the process.

Published: June 2021

RésuméL'objectif de ce papier est d'analyser l'effet des dépenses de santé et de l'état de santé sur la croissance économique en Afrique Subsaharienne (ASS). A cet effet, un modèle de panel dynamique a été utilisé pour un échantillon de 32 pays d'Afrique Subsaharienne couvrant la période 2005 à 2014 d'une part et pour une analyse approfondie concernant les régions de l'Est et de l'Ouest d'autre part. A cet effet, l'approche par la méthode des moments généralisés (GMM) a été utilisée pour obtenir les résultats dans le contexte africain. Cependant, l'estimateur des moindres carrés des variables muettes corrigé (LSDVC) a été utilisé pour les résultats concernant les deux régions d'Afrique (Est et Ouest). Les résultats issus des estimations montrent que le produit intérieur brut est principalement influencé positivement par les indicateurs de santé notamment l'espérance de vie et le taux de mortalité infanto‐juvénile, les dépenses de santé (publiques et privées) et la proportion des femmes dans la population active. L'implication politique qui découle de ce papier est que le revenu par habitant peut être augmenté par des politiques visant l'amélioration de l'état de santé de la population et de l'autonomisation des femmes.
Obedient Men and Obsessive Women: Donor Insemination, Gender and Psychology in Belgium
Authors: Claes Tinne 
Published: June 2021

AbstractDrawing on contemporary studies and oral history interviews, this article analyses psychiatric evaluations of heterosexual couples requesting donor insemination in Belgium in the 1970s. It contains two interrelated arguments. First, it reassesses the reason why mental health professionals were incorporated into fertility clinics. In response to negative assumptions about the mental stability of candidates seeking donor insemination, they had to act as gatekeepers. This finding contradicts earlier research, which linked the integration of mental health professionals in reproductive medicine to the growing awareness of the emotional consequences of infertility and to the exclusivity of in vitro fertilisation. Second, this article shows that psychiatric evaluations were influenced by both traditional gender roles and newer models of equality. As the mirror of a society that was changing at different speeds, they reflected both the transformation of traditional ideals of family, sex and marriage and the discomfort sparked by these changes.
A Struggle for Competence: National Security, Surveillance and the Scope of EU Law at the Court of Justice of European Union
Authors: Zalnieriute Monika 
Published: June 2021

AbstractIn Privacy International and Quadrature Du Net, the Grand Chamber of the CJEU ruled that the e‐Privacy Directive generally prevents bulk retention and transmission of traffic and location data, unless Member States can prove serious threats to national security. In such cases, bulk data can be retained during a strictly necessary period, subject to review by a court or independent administrative body. The judgments will impact other data retention and sharing arrangements, such as the PNR, proposed e‐Privacy Regulation and e‐Evidence package, and adequacy decisions under GDPR, including for post‐Brexit UK. The rulings suggest the CJEU's significance in national security, which has been outside of European integration, but has become a ground for political struggle between EU institutions and Member States. While Privacy International unequivocally asserts CJEU's authority in national security and is a victory for data protection, Quadrature Du Net does not oppose indiscriminate data retention in principle and is an ambivalent response to political pressure.
An overview of research of essential oils by self‐organizing maps: A novel approach for meta‐analysis study
Authors: Galvan Diego , Effting Luciane , Torres Neto Luiz , Conte‐Junior Carlos Adam 
Published: June 2021

AbstractEssential oils (EOs) are commercially important products, sources of compounds with antioxidant and antimicrobial activities considered indispensable for several fields, such as the food industry, cosmetics, perfumes, pharmaceuticals, sanitary and agricultural industries. In this context, this systematic review and meta‐analysis, a novel approach will be presented using chemometric tools to verify and recognize patterns of antioxidant, antibacterial, and antifungal activities of EOs according to their geographic, botanical, chemical, and microbiological distribution. Scientific papers were selected following the Preferred Reporting Items for Systematic Review and Meta‐Analyses statement flow diagram, and the data were evaluated by the self‐organizing map and hierarchical cluster analysis. Overall, this novel approach allowed us to draw an overview of antioxidants and antimicrobials activities of EOs reported in 2019, through 585 articles evaluated, obtaining a dataset with more than 10,000 data, distributed in more than 80 countries, 290 plant genera, 150 chemical compounds, 30 genera of bacteria, and 10 genera of fungi. The networks for geographic, botanical, chemical, and microbiological distribution indicated that Brazil, Asia, the botanical genus Thymus, species Thymus vulgaris L. “thyme,” the Lamiaceae family, limonene, and the oxygenated monoterpene class were the most representative in the dataset, while the species Escherichia coli and Candida albicans were the most used to assess the antimicrobial activity of EOs. This work can be seen as a guide for the processing of metadata using a novel approach with non‐conventional statistical methods. However, this preliminary approach with EOs can be extended to other sources or areas of food science.
Involvement of non‐coding RNAs during infection of rice by Acidovorax oryzae

Published: June 2021

SummaryThe expression of non‐coding RNAs (ncRNAs) has been observed in a variety of bacteria. However, the function of ncRNAs and their regulatory targets are largely unknown, and few ncRNAs are found to be associated with bacterial virulence. The bacterial brown stripe pathogen Acidovorax oryzae (Ao) RS‐1 shows a high level of condition‐dependent differential expression of ncRNA, which we identified in a genome wide screen. We experimentally validated 66 differentially expressed ncRNAs using an integrative analysis of conservative genome sequences and transcriptomic data during in vivo interaction of the bacterial pathogen with the rice plant. To test the relevance of the differentially expressed ncRNAs, we chose four with different positions within the genome, and with different secondary structures and promoter activities. The results show that the overexpression of the four ncRNAs caused a significant change in virulence‐related phenotypes, resistance to various environmental stresses, expression of secretion systems and effector proteins, while changing the expression of ncRNA putative target genes. We conclude that these ncRNAs are examples for the inherent regulatory roles for many of the observed ncRNAs in response to changing conditions such as host interaction or environmental adaption.

Published: June 2021

AbstractThe apically extruded debris caused by TruNatomy System (TRN), RACE EVO system (RE) and VDW Rotate (VR) systems in mandibular anterior teeth with ribbon‐shaped root canals were compared. The root canals (n = 20 in each group) were irrigated with NaOCl 2.5%, and the extruded debris was collected at pre‐weighted Eppendorf tubes. The amount of apically extruded debris (mg) and the treatment time (s) were recorded. Tukey pairwise comparisons were performed to compare groups with a 95% confidence level. VR had significantly less debris extrusion values and treatment time than RE and TRN (P < 0.05). Although no difference was observed between RE and TRN in terms of apically extruded debris (P > 0.05), a significant difference in favour of RE was observed in terms of treatment time (P < 0.05). All the instruments extruded debris at varying weights.

AbstractObjectiveTo explore physical activity changes and participation among physically active older adults living in retirement villages during the coronavirus (COVID‐19) pandemic.MethodsSemi‐structured interviews were conducted over the telephone. The interviews were recorded and transcribed verbatim. Reflexive thematic analysis was conducted.ResultsSeventeen older adults were interviewed, and they engaged in many types of physical activity before the COVID‐19 lockdown. During the COVID‐19 lockdown, the most common physical activity that older adults participated in was walking. Mental well‐being and socialisation were affected during the lockdown, with older adults employing several strategies to help them cope.ConclusionsDuring the COVID‐19 pandemic, physically active residents of retirement villages maintained their physical activity, but with reduced intensity and variety. In some cases, this impacted their mental and physical health. Physical activity resources aimed at facilitating diverse and sufficiently intense physical activity may benefit this group, and others.
