Published: January 2020

Purpose
Aerospace and defence industries use the materials having better properties at elevated temperatures, and Inconel 718 is one of that. The complexity in realizing complex and intricate shapes necessitate the product realization through additive manufacturing. This paper aims to investigate the wear behaviour of additive manufactured material.

Design/methodology/approach
The wear behaviour of additively manufactured Inconel 718 samples through direct metal laser sintering process at three different build orientations was experimentally investigated using a standard pin-on-disc wear tester.

Findings
Among the varied wear parameters, the load was identified as the most influencing parameter on the wear rate. In addition, the post-failure analysis of the worn surface of the pins under the scanning electron microscopy revealed the presence of various wear mechanisms.

Originality/value
Almost, the industries are now focussed on their production through additive manufacturing owing to its advantages. The present work displays the wear behaviour of the additive manufactured Inconel 718 and its associated wear mechanisms.

Study on the performance of gas foil thrust bearings with stacked bump foils
Authors: Hu Hongyang , Feng Ming , Ren Tianming 
Published: January 2020

Purpose
This paper aims to improve the load capacity of gas foil thrust bearing (GFTB) and to introduce and study a novel bearing with stacked bump foils.

Design/methodology/approach
For the proposed novel GFTB supported by stacked foils, some bump-type gaskets with several partial arches are inserted below the regular bump foil, and the height of each arch can be made differently. These features make the bump foil thickness and height gradually increase, which can bring enhanced support stiffness and convergent film at the trailing edge. Based on a new nonlinear bump stiffness model considering bump rounding and friction force, the finite element and finite difference method were used to solve the coupling Reynolds equation, energy equation and foil deformation equation. Finally, the structural stiffness and static characteristics of the novel GFTB were gained and compared with the traditional bearing.

Findings
The novel GFTB has an additional convergence effect in the parallel section, which improves the static performance of bearing. The bearing capacity, friction moment, power loss and temperature rise of the novel GFTB are all higher than those of the traditional bearing, and the static characteristics are related to the parameters of stacked bump foils.

Originality/value
The stacked bump foils bring a fundamental enhancement on the load capacity of GFTB. The results are expected to be helpful to bearing designers, researchers and academicians concerned.

Dimensions that influence the innovation process in justice organizations
Authors: Castro Marilú Pereira , Guimaraes Tomas Aquino 
Published: January 2020

Purpose
The purpose of this paper is to identify dimensions that can influence the innovation process in justice organizations.

Design/methodology/approach
This study uses a qualitative approach. Data were collected through a semi-structured interview script. In all, 23 in-depth interviews were undertaken with lawyers, public defenders, judges, prosecutors and public officials from the five regions of Brazil. These data were analyzed using content analysis techniques.

Findings
The perceptions of the interviewees show that the process of innovation in justice organizations can be influenced by five dimensions: Institutional Environment (institutional level), Leadership (organizational level), Organizational Resources (organizational level), Cooperative Relations (interorganizational level) and Innovative Behavior (individual level). These dimensions may promote or restrict innovation.

Originality/value
The results indicate that there are growing efforts to introduce innovations designed to improve the performance and service delivery of justice organizations. However, there is resistance to innovation because these organizations are highly institutionalized and consequently seek stability and absence of change.
Fiscal autonomy and stabilization: an empirical analysis of US state governments
Authors: Kim Sungchan 
Published: January 2020

PurposeEven though fiscal autonomy plays a role as one of the prerequisite conditions for fiscal decentralization, there has been little research into why fiscal autonomy is important or how it works for subnational governments. This study aims to examine the effectiveness of fiscal autonomy by using a panel dataset of US state governments from 2001 to 2013.Design/methodology/approachAccording to the results of general method of moments, the author find that fiscal autonomy leads to reducing volatility in total expenditures.FindingsIt indicates that fiscal autonomy is necessary for state governments performing one of the three Musgravian role of government (e.g. stabilization). However, when we look at the more detailed relationship between fiscal autonomy and volatility by applying expenditures from major categories such as capital outlay, general expenditure and public welfare, this study finds no statistically significant results. Interestingly, balanced budget requirement and tax and expenditure limitation indicate different effects on expenditure volatility, even though they belong to the same institutional factors.Originality/valueThis paper is meaningful because it can support the importance of fiscal autonomy on fiscal performance.

Three-way group decisions under hesitant fuzzy linguistic environment for green supplier selection
Authors: Ma Weimin , Lei Wenjing , Sun Bingzhen 
Published: January 2020

Purpose
The purpose of this paper is to propose a three-way group decision-making approach to address the selection of green supplier, by extending decision-theoretic rough set (DTRS) into hesitant fuzzy linguistic (HFL) environment, considering the flexible evaluation expression format of HFL term set (HFLTS) and the idea of minimum expected risk in DTRS.

Design/methodology/approach
Specifically, the authors first present the calculation method of the conditional probability and discuss the loss functions of DTRS with HFL element (HFLE), along with some associated properties being investigated in detail. Further, three-way group decisions rules can be deduced, followed by the cost of every green supplier candidate. Thus, based on these discussions, a novel green supplier selection DTRS model that combines multi-criteria group decision-making (MCGDM) and HFLTS is designed.

Findings
A numerical example of green supplier selection, the comparative analysis and associated discussions are conducted to illustrate the applicability and novelty of the presented model.

Practical implications
The selection of green supplier has played a critically strategic role in sustainable enterprise development due to continuous environmental concerns. This paper offers an insight for companies to select green supplier selection from the perspective of three-way group decisions.

Originality/value
This paper uses three-way decisions to address green supplier selection in the HFL context, which is considered as a MCGDM issue.
Social intra-organizational connection: effects in three relational domains
Authors: Maciel Cristiano de Oliveira 
Published: January 2020

Purpose
The purpose of this paper is to present the construct of social intra-organizational connection (SIC). This construct reflects the extent to which a focal actor believes his alters present behaviors of social inclusion in relation to himself. This assessment compares the ego’s expectations of being included and the behavior of inclusion performed by those alters with whom the actor has more frequent interactions. The effects of this construct are tested in the organizational domain regarding the intention to leave, in the domain of co-workers regarding cooperation and in the family domain regarding work–family conflict.

Design/methodology/approach
The survey data were collected from 380 Brazilian workers.

Findings
The results confirmed the effects of SIC in the relational domain of the organization through the variation in the focal actor’s intention to leave. In the sphere of coworkers, the effects of SIC were found in the variation of the degree of cooperation. In the family sphere, SIC had an influence upon the intensity of the work–family conflict.

Originality/value
The research indicates that the behavior of making direct contacts and more frequent interactions by the focal actor extends to other relational spheres through the transitions of the organizational member between the domains of organization, coworkers and family. This paper draws attention to the need to consider the local networks, both within and beyond the organization, and their effects on each other.

Authors: Abioye Taiwo Ebenezer , Omotehinse Igbekele Samson , Oladele Isiaka Oluwole , Olugbade Temitope Olumide , Ogedengbe Tunde Isaac 
Published: January 2020

PurposeThe purpose of this study is to determine the effects of post-annealing and post-tempering processes on the microstructure, mechanical properties and corrosion resistance of the AISI 304 stainless steel gas metal arc weldment.Design/methodology/approachGas metal arc welding of AISI 304 stainless steel was carried out at an optimized processing condition. Thereafter, post-annealing and post-tempering processes were performed on the weldment. The microstructure, mechanical and electrochemical corrosion properties of the post-weld heat treated samples, as compared with the as-welded, were investigated.FindingsThe as-welded joint was characterized with sub-granular grain structure, martensite formation and Cr-rich carbides precipitates. This made it harder than the post-annealed and post-tempered joints. Because of slower cooling in the furnace, the post-annealed joint contained Cr-rich carbides precipitates. However, the microstructure of the post-tempered joint is more refined and significantly devoid of the carbide precipitates. Post-tempering process improved the elongation (∼23%), tensile (∼10%) and impact (∼31%) strengths of the gas metal arc AISI 304 stainless steel weldment, while post-annealing process improved the elongation (∼20%) and impact strength (∼72%). Owing to the refined grain structure and significant elimination of the Cr-rich carbide precipitates at the joint, the post-tempered joint exhibited better corrosion resistance in 3.5 Wt.% NaCl solution than the post-annealed and the as-welded joints.Originality/valueThe appropriate post-weld heat treatment that enhances microstructural homogeneity and quality of the AISI 304 gas metal arc welded joint was determined.
Novel plant–microbe interactions: Rapid evolution of a legume–rhizobium mutualism in restored prairies
Authors: Magnoli Susan M. , Lau Jennifer A. 
Published: January 2020

Abstract

When plants colonize new habitats, the novel interactions they form with new mutualists or enemies can immediately affect plant performance. These novel interactions also may provoke rapid evolutionary responses and can be ideal scenarios for investigating how species interactions influence plant evolution.

To explore how mutualists influence the evolution of colonizing plant populations, we capitalized on an experiment in which two former agricultural fields were seeded with identical prairie seed mixes in 2010. Six years later, we compared how populations of the legume Chamaecrista fasciculata from these sites and their original (shared) source population responded to nitrogen‐fixing rhizobia from the restoration sites in a greenhouse reciprocal cross‐inoculation experiment.

We found that the two populations differed both from their original source population and from each other in the benefits they derive from rhizobia, and that one population has evolved reduced allocation to rhizobia (i.e. forms fewer rhizobium‐housing nodules).

Synthesis. Our results suggest that these plant populations have evolved different ways of interacting with rhizobia, potentially in response to differences in rhizobium quality between sites. Our study illustrates how microbial mutualists may shape plant evolution in new environments and highlights how variation in microbial mutualists potentially may select for different evolutionary strategies in plant hosts.
Community assembly of the native C. elegans microbiome is influenced by time, substrate and individual bacterial taxa
Authors: Johnke Julia , Dirksen Philipp , Schulenburg Hinrich 
Published: January 2020

SummaryMicrobiome communities are complex assemblages of bacteria. The dissection of their assembly dynamics is challenging because it requires repeated sampling of both host and source communities. We used the nematode Caenorhabditis elegans as a model to study these dynamics. We characterized microbiome variation from natural worm populations and their substrates for two consecutive years using 16S rDNA amplicon sequencing. We found conservation in microbiome composition across time at the genus, but not amplicon sequencing variant (ASV) level. Only three ASVs were consistently present across worm samples (Comamonas ASV10859, Pseudomonas ASV7162 and Cellvibrio ASV9073). ASVs were more diverse in worms from different rather than the same substrates, indicating an influence of the source community on microbiome assembly. Surprisingly, almost 50% of worm‐associated ASVs were absent in corresponding substrates, potentially due to environmental filtering. Ecological network analysis revealed strong effects of bacteria–bacteria interactions on community composition: While a dominant Erwinia strain correlated with decreased alpha‐diversity, predatory bacteria of the Bdellovibrio and like organisms associated with increased alpha‐diversity. High alpha‐diversity was further linked to high worm population growth, especially on species‐poor substrates. Our results highlight that microbiomes are individually shaped and sensitive to dramatic community shifts in response to particular competitive species.

Published: January 2020

AbstractThe interpretation of sharp force fatality dynamics may be difficult in some cases, but a contribution to analysis of the phenomenon may be provided by case studies. Therefore, the purpose of our study is focused on identifying, in observed sharp force fatalities, reliable parameters that can differentiate a homicidal and suicidal manner of death, with particular reference to criminological parameters. Data derived from sharp force fatality cases in Padua and Venice from 1997 to 2019, anonymized and collected in Excel, included personal, circumstantial, clinical, and psychopathological–criminological data, as well as crime scene investigation, necroscopic, and toxicological data. Statistical analyses were performed using chi‐square and Wilcoxon rank‐sum tests. Possible predictors of homicide were analyzed by logistic regression. Six parameters (bloodstains distant from the body, clothing lacerations, hesitation/defense wounds, number of injuries, and potential motives) were significantly different in the two groups (p < 0.05). An independent statistical association between potential motives explaining the crime (p < 0.001; OR 27.533) and homicide on multiple logistic regression analysis was highlighted. The absence of clothing lacerations was inversely related to homicide (p = 0.002, OR 0.092). To the best of our knowledge, this is one of very few Italian studies concerning the differential diagnosis between homicidal and suicidal sharp force fatalities. The dynamics of the event is established in most cases by the integrated evaluation of data from crime scene investigation and the autopsy. Nevertheless, in an atypical scenario, a psychopathological–criminological analysis may provide essential elements, and particular attention should be given to the identification of potential explanatory motives.
A Case of Multiple Self‐Inflicted Stab Wounds of the Neck Captured on Surveillance Video
Authors: Alunni Véronique , Cabusat‐Mailliet Coraline , Quatrehomme Gérald 
Published: January 2020

AbstractMultiple sharp force injuries in a victim make it difficult to distinguish between homicide and suicide. Forensic pathologists also may be unable to determine the total survival time and the survival time with physical activity due to lack of evidence. The authors report here on a case of nineteen stab wounds of the neck, which led to an initial suspicion of homicide. The scene was however captured on surveillance video, which provided a precise description of the wound mechanism and led to the injuries being reclassified as suicidal. No other description of a suicide with such a high number of severe stab wounds has been documented in the literature. The video footage provided additional information concerning survival time. Physical activity was well documented during at least 4 min after the last stab wound and the total survival period was at least 6 min, despite the perforation of both jugular veins and the trachea. Vein injuries are less rapidly lethal than artery injuries. Injuries of the major airways are not immediately lethal and do not lead to immediate incapacitation. The benefit of the video evidence is to highlight wound features that may suggest a suicidal manner and inform forensic pathologists about survival intervals after severe stab wounds to the neck.
